The working principle of the multifunctional automatic packaging all-in-one machine for the cross-border e-commerce online store provided by this embodiment is that when a sealed carton is bundled, the first motor is started in the forward direction, so that the strapping tape advances along the extrusion conveying channel formed by the upper conveying wheel 15 and the lower conveying wheel 16, at this time, the power provided by the upper conveying wheel 15 and the lower conveying wheel 16 to the strapping tape is large, so that the strapping tape generates a pulling force, which is much larger than the sum of the gravity of the rod body 802 and the roller 803, so that the rod body 802 moves upward, that is, moves toward the inner side of the pipe body 801, at this time, the length of the pressing mechanism 8 is continuously shortened until reaching a short limit state, at this time, the gravity of the rod body 802 and the roller 803 still generates a downward pressure on the advancing strapping tape, when the pulling force on the strapping tape is suddenly reduced to be smaller than the gravity of the rod body 802 and the roller 803 or when the pulling force suddenly disappears, under the action of the self gravity of the rod body 802 and the roller 803, the strapping tape can be immediately tensioned, so that the looseness is prevented; when the strapping tape returns, the tension on the strapping tape disappears, the strapping tape is in a loose state instantly, and at the moment, the strapping tape moves downwards along the inner cavity of the pipe body 801 under the action of the self gravity of the rod body 802 and the roller 803, so that the strapping tape in the loose state is tensioned, and the strapping tape is prevented from being twisted and bent. Among the prior art, when returning unnecessary length's strapping, because the strapping has backward power, along with returning the increase of length, cause the loose of strapping very easily, moreover, the strapping that returns is direct loose falls into the temporary storage space that is formed by a cavity, when the length of the strapping that returns is longer, loose strapping is piled up in the temporary storage space, the condition that each section orientation differs appears easily, when moving forward with the strapping is taut again, cause the torsional bending of strapping very easily to cause the phenomenon of card area. Compared with the prior art, the invention has the main innovation point that the pressure applying mechanism 8 is added, so that the strapping tape can be always kept in a tensioned state on the premise of meeting the original function, and the condition of tape clamping is ensured not to occur.

In this embodiment, by providing the pressing mechanism 8, when the strapping tape is conveyed by the upper conveying wheel 15 and the lower conveying wheel 16, the advancing strapping tape presses the roller 803, so that the rod body 802 moves towards the inner side of the pipe body 801 until the strapping tape moves to the short limit state, and the strapping tape is in a tensioned state, and the roller 803 has a pressing force on the advancing strapping tape due to the sliding connection of the rod body 802 and the inner cavity of the pipe body 801, so that the strapping tape can be prevented from being loosened; when the strapping tape returns, the pressure of the strapping tape on the roller 803 disappears, the rod body 802 moves towards the outer side of the pipe body 801, and the roller 803 extrudes the strapping tape to tension the strapping tape until the returned strapping tape is completely in a tension state.

In this embodiment, the pipe body 801 is a square body or a polygonal body as the rod body 802, and the limitation on the rod body 802 can be realized, so that the rod body 802 can only reciprocate along the inner cavity of the pipe body 801 without rotating, and the roller 803 does not rotate, thereby improving the stability of the pressing mechanism 8.

In this embodiment, the pipe 801 may be vertically disposed or may be disposed to be inclined from left to right, and the inclination angle is not greater than 30 °.

In the present embodiment, the apparatus further includes a pressurizing mechanism 7 for increasing the moving resistance of the binding tape, the pressurizing mechanism 7 is located upstream of the pressurizing mechanism 8, and the frictional force between the pressurizing mechanism 7 and the binding tape is larger than the pressure of the roller 803 against the binding tape in the retracted state of the binding tape. The pressurizing mechanism 7 is used for pressurizing the strapping tape so as to increase the moving resistance of the strapping tape, namely the friction force between the pressurizing mechanism 7 and the strapping tape, the resistance value is far smaller than the pulling force generated when the strapping tape advances, but is larger than the pressure of the roller 803 on the strapping tape in the return state of the strapping tape, namely, is larger than the sum of the gravity of the rod body 802 and the gravity of the roller 803, the resistance force is mainly used in the return state of the strapping tape, when the roller 803 presses and tensions the loose strapping tape downwards, the upstream end of the strapping tape is fixed by the pressurizing mechanism 7 and cannot be pulled, and the squeezed and tensioned strapping tape is all in the return part, so that the pressurizing mechanism 8 can efficiently realize the aim of keeping tension on the returned long strapping tape; at the same time, the pressurizing mechanism 7 ensures that the returned strapping tape generates 'backflow', so that the strapping tape is loosened, and the limiting of the strapping tape is completed.

In the present embodiment, the pressing mechanism 8 and the pressurizing mechanism 7 are connected to the bundling mechanism 2 through the housing 3, both the pressing mechanism 8 and the pressurizing mechanism 7 are disposed in the housing 3, the housing 3 is disposed outside the bundling mechanism 2, and the housing 3 is provided with the transparent protective door 5. Can conveniently install the operation to the strapping tape through setting up casing 3 in the outside of strapping mechanism 2, utilize transparent guard gate 5 can make things convenient for whether the strapping tape operation of staff in the work of outside direct observation is normal moreover to can open guard gate 5 when installing the strapping tape, make the operation more convenient.

In order to prevent the strapping tape from contacting and rubbing with the inner wall of the through hole, a first protection wheel 6 is fixedly installed on the side plate of the shell 3, the first protection wheel 6 is positioned right below the through hole, and the strapping tape is attached to and wound around the first protection wheel 6, so that the strapping tape cannot contact with the inner wall of the through hole.

In a preferred embodiment, the booster mechanism 7 comprises an upper balance 701 and a lower pulley 702 arranged one above the other, the upper balance 701 and the lower pulley 702 being pressed against each other. The strapping tape passes through between the upper balance wheel 701 and the lower rotary wheel 702, and the strapping tape generates friction force between the strapping tape and the upper balance wheel 701 and the lower rotary wheel 702 by utilizing the pressing force between the upper balance wheel 701 and the lower rotary wheel 702, so that the limiting and fixing of the pressurizing mechanism 7 on the retracted strapping tape are realized.

Further, the upper balance wheel 701 is connected with the shell 3 in a swinging mode through a connecting plate, the upper portion of the connecting plate is connected with the inner wall of the shell 3 in a swinging mode through a torsion spring, and the lower portion of the connecting plate is connected with the upper balance wheel 701 in a rotating mode through a transverse shaft. When the frictional force between the pressurizing mechanism 7 and the binding tape is larger than the pressure of the roller 803 against the binding tape in the retracted state of the binding tape, the frictional force between the pressurizing mechanism 7 and the binding tape in the advancing state of the binding tape can be appropriately reduced, and the smoothness of the advancing of the binding tape can be improved. Therefore, with the oscillating design of the upper balance wheel 701 and the rotating design of the upper balance wheel 701, when the binding tape travels, the upper balance wheel 701 oscillates in the traveling direction, so that the pressing force applied to the binding tape is reduced, and the upper balance wheel 701 rotates to further reduce the friction force.

Still further, the lower runner 702 is connected with the inner wall of the housing 3 through a cross shaft, one end face of the cross shaft is fixedly connected with the housing 3, and the lower runner 702 is rotatably sleeved on the cross shaft, so that when the strapping tape advances, the lower runner 702 also rotates along with the strapping tape, and the friction force between the strapping tape and the pressurizing mechanism 7 can be further reduced.

When the carton is less, the length of the strapping that is returned can be longer, in order to satisfy the effective tensioning to longer strapping, in this embodiment, mechanism 8 and booster mechanism 7 all can set up a plurality ofly, a plurality of mechanisms 8 all set up regulating wheel 12 between two liang and a plurality of booster mechanisms 7 of exerting pressure, regulating wheel 12 rotates and sets up in casing 3, regulating wheel 12 and strapping butt, when the strapping removes, can drive regulating wheel 12 and rotate, regulating wheel 12 is used for adjusting the direction of strapping. The plurality of pressure applying mechanisms 8 are arranged in parallel left and right, and the height of the adjusting wheel 12 arranged between every two pressure applying mechanisms 8 is larger than that of the roller 803 on each pressure applying mechanism 8, so that the moving strapping tape can respectively have upward tension on each roller 803; the plurality of pressurizing mechanisms 7 may be arranged in parallel or may be arranged vertically offset, so long as the height of the adjusting wheel 12 installed between every two pressurizing mechanisms 7 is lower than the height of the pressurizing mechanisms 7 (so that the moving strapping tape has a downward tension to each lower runner 702, but not an upward tension to the upper balance wheel 701, and the stability during the movement of the strapping tape is ensured), and the height of the pressurizing mechanisms 7 is higher than the height of the roller 803 (so that the roller 803 on the pressing mechanism 8 close to the pressurizing mechanisms 7 can receive an upward tension to the moving strapping tape).

The length of the tightening treatment of the strapping tape can be effectively increased by the cooperation of the plurality of pressing mechanisms 8, so that the tightening of the returned longer strapping tape is satisfied; the pressure of the roller 803 on the returning strapping tape is increased by the cooperation of the plurality of pressure applying mechanisms 8, and the corresponding utilization of the plurality of pressure applying mechanisms 7 ensures effective fixation of the upstream end of the strapping tape and prevents the upstream end of the strapping tape from moving.

Further, a ring-shaped groove (not shown) for guiding the binding tape is provided on the roller 803, and the total length of the rod body 802 and the roller 803 is greater than the length from the bottom of the pipe body 801 to the bottom of the housing 3. Because the total length of the rod 802 and the roller 803 is greater than the length from the bottom of the pipe 801 to the bottom of the housing 3, when the roller 803 moves down to contact with the bottom of the housing 3, the rod 802 still cannot completely slide out of the pipe 801, the stability of the pressing mechanism can be ensured, and the strapping tape passes through the annular groove on the roller 803, the depth of the annular groove is greater than the thickness of the strapping tape, so that when the roller 803 contacts with the bottom of the housing 3, the strapping tape cannot be pressed by the roller, and the tensioning operation of the strapping tape by other pressing mechanisms 8 is not affected.

In order to further increase the length of the strapping tape in a limited space, as shown in fig. 4, the adjusting wheel 12 between each two of the plurality of pressing mechanisms 8 is an inverted pressing mechanism 8 (i.e. the roller 803 is located above), the rod body 802 of the inverted pressing mechanism 8 is in dynamic sealing connection with the inner cavity of the pipe body 801 through the piston 9, the pipe body 801 is communicated with the pressure distribution pipe 10, and the inner cavity of the pressure distribution pipe 10 is provided with the gravity block 11 in dynamic sealing. The gravity of the gravity block 11 is greater than the sum of the gravity of the rod body 802 and the roller 803, but is far less than the tension value of the strapping tape in the advancing state, when the strapping tape returns, under the action of the gravity block 11, the gravity block 11 moves downwards along the inner cavity of the pressure distribution pipe 10, and pushes the piston 9 to move upwards, the piston 9 drives the rod body 802 and the roller 803 to move upwards together, so that the roller 803 extrudes the strapping tape upwards, the processing length of the strapping tape is increased, the volume of the shell 3 is not additionally increased, and the purpose of further increasing the processing length of the strapping tape in a limited space is achieved. When the strap is advanced again, the strap will press down on roller 803, causing roller 803 to return to the short limit condition.

The diameter of the inscribed circle of the inner cavity of the pressure distribution pipe 10 is larger than that of the inscribed circle of the inner cavity of the pipe body 801, so that the length of the pressure distribution pipe 10 is reduced, the space can be saved, and the position can be placed conveniently.

Further, the inner cavity of the pressure distribution pipe 10 is filled with lubricating oil, and the friction between the piston 9 and the pipe body 801 and the friction between the gravity block 11 and the pressure distribution pipe 10 can be reduced by using the lubricating oil.

Furthermore, one of the pressurizing mechanisms 7 is attached to the inner wall of the housing 3, so that if the strapping tape moves back, the strapping tape drives the upper balance wheel 701 to swing back under the action of friction force, and at the moment, the upper balance wheel 701 extrudes the inner wall of the housing 3, so that the upper balance wheel 701 simultaneously receives swinging and rotating resistance to prevent the upper balance wheel 701 from swinging and rotating, and therefore, the friction force of the pressurizing mechanisms 7 on the strapping tape is not reduced, the limiting on the strapping tape is completed, and the strapping tape on the strapping disc 4 cannot be loosened due to the fact that the strapping tape flows back outwards from the inside of the housing 3; and the pressurizing mechanism 7 is positioned to correspond to the through hole so that the lower runner 702 is engaged with the first protection wheel 6 to ensure that the binding band does not contact the inner wall of the through hole in the housing 3.

Under the natural action of the elastic connecting piece 26, the two first baffles 2102 are abutted or nearly abutted with each other, the vertical distance between the two second baffles 2103 is smaller than the width of the strapping tape, and the strapping tape cannot pass through the two second baffles 2103 when moving in the travelling track 2101, so that the guiding effect of the strapping tape is realized; when the binding tape is retracted, the two second stoppers 2103 are momentarily pressed against the connecting device 26 to the outside by the tensile force applied to the binding tape by the upper feed wheel 15 and the lower feed wheel 16, and the two second stoppers 2103 move in opposite directions to increase the distance therebetween, so that the binding tape passes through between the two second stoppers 2103. The design mode can lead the strapping tape to smoothly complete the movement of the designated route, and simultaneously can be easily separated from the travelling track 2101 without other electronic drive, such as an air cylinder or a motor, thereby saving electric energy and equipment cost.

The travelling track 2101 has two ports, an inlet end 24 and an outlet end 25, respectively, and a strapping tape is passed into the travelling track 2101 from the inlet end 24 and then out from the outlet end 25, wherein the inlet end 24 has a height higher than that of the outlet end 25, so that the strapping tape passed out from the outlet end 25 is positioned on the upper portion of the strapping tape which is not passed into the travelling track 2101, thereby facilitating the later hot-ironing and bonding of the strapping tape;

meanwhile, the width of the inlet end 24 is larger than that of the outlet end 25, and the inlet end 24 is wider, so that the strapping tapes can be ensured to enter the travelling track 2101 smoothly;

each corner of the first shutter 2102 and the second shutter 2103 is curved to ensure that the strap can smoothly move in the travel rail 2101.

The actuator 201 comprises a supporting shell 23 and a power mechanism 22 which play a supporting role, the shell 3 is fixedly connected with the supporting shell 23, the supporting shell 23 is fixedly connected with the two mounting plates 2001 on the outer shell 2003 through bolts, the two mounting plates 2001 are positioned on the top surface of the supporting shell 23, so that the guide rail mechanism 202 is fixedly connected with the actuator 201, and the guide rail mechanism 202 and the actuator 201 can be conveniently detached through the connection mode of the bolts. The top surface of the supporting shell 23 is provided with an insertion hole, which allows the bottom of the rail mechanism 202 to be just inserted, so that the bottom of the traveling rail 2101 is located inside the supporting shell 23, and thus, when the carton is bundled by the bundling belt, one-turn winding of the carton can be realized.

Wherein, the through holes 2209 for the strapping tapes to penetrate are arranged on the first vertical plate 2201 and the abutting plate 2202, the through holes 2209 on the first vertical plate 2201 are correspondingly connected with one end of the guide pipe 14, the heights of the through holes 2209 on the first vertical plate 2201 and the abutting plate 2202 are consistent in a natural state (when the second motor 2216 is not operated, the second lifting plate 2207 and the first lifting plate 2214 are in an initial state), so that the strapping tapes penetrating out of the guide pipe 14 can smoothly enter the two through holes 2209 in sequence, and in the natural state, the top height of the knife 2203, the top height of the second vertical plate 2204, the top height of the third vertical plate 2208 and the bottom height of the through holes 2209 are consistent and higher than the top height of the ironing head 2206 (preventing the strapping tapes in progress from being ironed), and the top height of the third vertical plate 2208 is not lower than the bottom height of the inlet end 24 and lower than the top height of the inlet end 24, with this height setting, the strapping tape passed through the through-hole 2209 can fall directly to the tops of the shear knife 2203, the second vertical plate 2204, and the third vertical plate 2208, thereby smoothly entering from the inlet end 24 into the travel rail 2101.

Further, a notch is formed in the top of the third vertical plate 2208, a paving plate 2205 is hinged in the notch through a torsion spring, in an initial state, the paving plate 2205 is in a horizontal state and located above the ironing head 2206, when the ironing head 2206 ascends, the ironing head 2206 rotates and jacks the paving plate 2205, and after the ironing head 2206 descends to an initial position, the paving plate 2205 can be restored to the initial position under the action of the torsion spring. And in the initial state, the top height of the plank 2205 is consistent with that of the third vertical plate 2208, so that the top height of the plank 2205 and the top height of the third vertical plate 2208 play a role of a bridge between the second vertical plate 2204 and the third vertical plate 2208, and the running strapping can be prevented from being clamped between the second vertical plate 2204 and the third vertical plate 2208.
