Detailed Description

In order that the present invention may be more readily and clearly understood, a more particular description of the invention briefly described above will be rendered by reference to specific embodiments that are illustrated in the appended drawings.

In the field of current textile processing, large batches of cloth often need to be printed and dyed. The printing work is generally performed by a printing machine. The existing dyeing machine is provided with a plurality of moving parts, a power source is required to be arranged for each moving part, the structure of the dyeing machine is complex, independent operation is performed between the moving parts, linkage is lacked, and the control of the dyeing machine is complicated.

In view of this, referring to fig. 1 to 6 and 8, a first embodiment of the present invention provides a printing and dyeing apparatus for polyester filament fabric, which includes a feeding mechanism, a printing and dyeing mechanism and a printing and dyeing body 8 driving mechanism, wherein a rotating motor 3 in the feeding mechanism is used to cooperate with a linkage component to provide a power source for the printing and dyeing driving mechanism, so that the number and installation structure of driving devices are reduced, and the cost is reduced; meanwhile, the feeding mechanism and the printing and dyeing mechanism are linked, so that the starting and stopping of the whole device are controlled more conveniently.

Specifically, the feeding mechanism comprises a material conveying roller 1 and a driving device for driving the material conveying roller 1 to rotate. The drive means comprises a first driving pulley 2, a first driven pulley 4 and a rotating electrical machine 3 driving the first driving pulley 2. The first driven wheel 4 is coaxially and fixedly arranged at the end part of the material conveying roller 1, and the first driving wheel 2 is matched with the first driven wheel 4. The first driving wheel 2 is provided with a toothed part 5 and a toothless part 6, the toothed part 5 of the first driving wheel 2 can be meshed with the latch of the first driven wheel 4, and at the moment, the first driving wheel 2 can drive the first driven wheel 4 to rotate; when the toothed part 5 of the first driving wheel 2 is disengaged from the latch of the first driven wheel 4, the first driving wheel 2 cannot rotate to drive the first driven wheel 4 to rotate, so that the first driven wheel 4 can obtain intermittent motion.

The first driven wheel 4 has two types of latch, one type is a normal latch engaged with the first driving wheel 2, the other type is a locking latch 19, and the locking latch 19 is located on two sides of the normal latch section. The end of the locking latch 19 is arc-shaped and the arc shape matches the end shape of the toothless part 6 of the first driving wheel 2. The toothed part 5 of the first driving wheel 2 is meshed with the normal latch of the first driven wheel 4 to drive the first driven wheel 4 to rotate; after the toothed part 5 of the first driving wheel 2 is disengaged from the normal latch of the first driven wheel 4, the end part of the locking latch 19 is attached to the end surface of the toothless part 6 of the first driving wheel 2, and at this time, the toothless part 6 of the first driving wheel 2 can apply a limiting force to the end part of the locking latch 19, so that the first driven wheel 4 cannot rotate continuously under the action of inertia.

The printing mechanism includes a printing table 7 and a printing body 8 mounted on the printing table 7. The two sides of the printing and dyeing platform 7 are symmetrically provided with supporting columns 15, and one opposite side of the two supporting columns 15 is correspondingly provided with a sliding groove 16 along the vertical direction. Both sides of the printing body 8 are slidably mounted in the sliding grooves 16, so that the printing body 8 can slide up and down along the sliding grooves 16. The lower end surface of the printing body 8 is set as a printing surface 9, and the printing body 8 can move downwards until the printing body is pressed on the cloth on the printing table 7 to print and dye the cloth.

The printing body 8 driving mechanism is in transmission connection with the printing body 8. Specifically, the driving mechanism of the printing and dyeing body 8 comprises a second driving wheel 10, a second driven wheel 11 and a transmission rod 12. The second driving wheel 10 is connected with the second driven wheel 11 through a driving wheel 13, and the second driving wheel 10, the driving wheel 13 and the second driven wheel 11 are rotatably arranged on the inner side of the supporting upright post 15. When the second driving wheel 10 rotates in any direction, the driving wheel 13 is engaged with the driving wheel 13 to drive the driving wheel 13 to rotate in the opposite direction, and the driving wheel 13 is engaged with the second driven wheel 11 to enable the second driven wheel 11 and the second driving wheel 10 to rotate in the same direction, and the synchronous linkage is realized, that is, when the second driving wheel 10 rotates, the second driven wheel 11 rotates along with the second driving wheel.

Wherein, fan-shaped gears 14 are coaxially and fixedly arranged on the second driving wheel 10 and the second driven wheel 11, and the shapes of the two fan-shaped gears 14 are matched with the shape of the clamping teeth arranged on the two fan-shaped gears. The transmission rod 12 and the two sector gears 14 are located in the same plane, the transmission rod 12 is located between the two sector gears 14, and clamping teeth matched with the sector gears 14 are arranged on two sides of the transmission rod 12. When the second driving wheel 10 and the second driven wheel 11 rotate synchronously, the two sector gears 14 are alternately meshed with the latch on the transmission rod 12 to drive the transmission rod 12 to reciprocate in the vertical direction. The lower end of the transmission rod 12 is connected with the printing and dyeing body 8, and then the printing and dyeing body 8 can be driven to lift through the lifting of the transmission rod 12, so that the printing and dyeing work of the cloth is completed.

It should be noted that the above-mentioned driving mechanisms for the printing and dyeing body 8 are installed on the inner sides of the two supporting columns 15, that is, both sides of the printing and dyeing body 8 are driven by the driving rod 12, so that the forces on both sides of the printing and dyeing body 8 are balanced during the process of up-and-down movement of the printing and dyeing body 8, and the printing and dyeing effect is prevented from being affected by the inclination of the printing and dyeing body 8 during the process of up-and-down movement.

It should also be noted that, a limiting shaft sleeve 17 for limiting the moving direction of the transmission rod 12 is disposed on the inner side of the support column 15, a limiting hole 18 along the vertical direction is formed in the limiting shaft sleeve 17, the size of the limiting hole 18 is slightly larger than the size of the end face of the transmission rod 12, and the transmission rod 12 passes through the limiting hole 18. The limiting shaft sleeve 17 has a horizontal limiting effect on the transmission rod 12, so that the transmission rod 12 can only move in the vertical direction.

Wherein, the second driving wheel 10 is connected with the first driven wheel 4 through a transmission belt in a transmission way. Namely, when the first driven wheel 4 rotates, the first driven wheel 4 drives the second driving wheel 10 to rotate through the transmission belt, so that the second driving wheel 10 and the first driven wheel 4 have synchronous linkage, and the whole printing and dyeing equipment has linkage by combining the synchronous linkage between the second driving wheel 10 and the second driven wheel 11 and between the sector gear 14 and the transmission rod 12.

When first action wheel 2 drives first from the rotatory time of driving wheel 4, it is rotatory that first from driving wheel 4 drives defeated material roller 1, simultaneously, first from driving wheel 4 drives second action wheel 10 rotation through driving belt, and second action wheel 10 drives the second again through drive wheel 13 and follows driving wheel 11 rotation, second action wheel 10 and second drive sector gear 14 rotation respectively from driving wheel 11, two sector gear 14 drive transfer line 12 along vertical direction reciprocating motion again jointly to drive printing and dyeing body 8 and go up and down, accomplish the printing and dyeing to the surface fabric.

Wherein, because the first driving wheel 2 comprises the toothed part 5 and the toothless part 6, when the toothed part 5 is meshed with the latch of the first driven wheel 4, the first driving wheel 2 can drive the first driven wheel 4 to rotate, and the printing and dyeing body 8 moves while the material conveying roller 1 rotates to convey material; when the toothless part 6 of the first driving wheel 2 is matched with the first driven wheel 4, the material conveying roller 1 stops feeding, so that the cloth on the printing and dyeing platform 7 is fixed, and the printing and dyeing body 8 can be pressed on the cloth to print and dye the cloth, thereby realizing intermittent feeding and printing and dyeing.

It should be noted that, certain conditions are required to be satisfied between three variables, namely, the time for completing one-time meshing between the toothed part 5 on the first driving wheel 2 and the first driven wheel 4, the width of the printing and dyeing body 8 and the time for completing one-time lifting of the printing and dyeing body 8, that is, after the toothed part 5 on the first driving wheel 2 and the first driven wheel 4 complete one-time meshing, the first driven wheel 4 drives the material conveying roller 1 to rotate and complete one-time material conveying, and the moving distance of the cloth in the material conveying is equal to the printing and dyeing width of the printing and dyeing body 8; in addition, the time for finishing one-time material conveying is equal to the time for finishing one-time lifting of the printing and dyeing body 8, and the two parts are linked, namely, when the cloth starts to move after finishing one-time printing and dyeing, the printing and dyeing body 8 starts to lift, and when the cloth finishes moving, the printing and dyeing body 8 finishes one-time lifting, and at the moment, the printing and dyeing body 8 is pressed on the surface of the cloth again. Through the control of the variables, the printing and dyeing on one section of cloth are continuous, and the phenomenon that the printing and dyeing body 8 is pressed on the cloth to block the movement of the cloth when the cloth moves can not occur.

Therefore, the invention can provide power source for all power parts by one rotating motor 3, reduce the number of driving devices and the installation structure, and ensure the printing and dyeing work circulation and consistency and the printing and dyeing work efficiency.

Referring to fig. 2 to 10, a second embodiment is provided for the printing and dyeing equipment for the polyester filament fabric, which is different from the first embodiment: in this embodiment, the feeding mechanism further comprises guide rollers, the guide rollers comprise a first guide roller 20 and a second guide roller 21, the first guide roller 20 and the second guide roller 21 are tangent, and the printing table 7 is located on the same plane as the common tangent plane of the first guide roller 20 and the second guide roller 21. The cloth delivered by the delivery roller 1 is guided by the guide roller, so that the cloth enters the printing and dyeing platform 7 along the horizontal direction, and meanwhile, the guide roller can keep the cloth tensioned, thereby avoiding printing and dyeing of the cloth in a wrinkle state.

Specifically, the main body of the apparatus includes a feeding mechanism, a printing mechanism, and a printing body 8 driving mechanism. The rotary motor 3 in the feeding mechanism is matched with the linkage part to provide a power source for the printing and dyeing driving mechanism, so that the number and the installation structure of the driving devices are reduced, and the cost is reduced; meanwhile, the feeding mechanism and the printing and dyeing mechanism are linked, so that the starting and stopping of the whole device are controlled more conveniently.

Wherein, feeding mechanism includes defeated material roller 1, drive defeated material roller 1 pivoted drive arrangement and guide roll. The drive means comprises a first driving pulley 2, a first driven pulley 4 and a rotating electrical machine 3 driving the first driving pulley 2. The first driven wheel 4 is coaxially and fixedly arranged at the end part of the material conveying roller 1, and the first driving wheel 2 is matched with the first driven wheel 4. The first driving wheel 2 is provided with a toothed part 5 and a toothless part 6, the toothed part 5 of the first driving wheel 2 can be meshed with the latch of the first driven wheel 4, and at the moment, the first driving wheel 2 can drive the first driven wheel 4 to rotate; when the toothed part 5 of the first driving wheel 2 is disengaged from the latch of the first driven wheel 4, the first driving wheel 2 cannot rotate to drive the first driven wheel 4 to rotate, so that the first driven wheel 4 can obtain intermittent motion.

The first driven wheel 4 has two types of latch, one type is a normal latch engaged with the first driving wheel 2, the other type is a locking latch 19, and the locking latch 19 is located on two sides of the normal latch section. The end of the locking latch 19 is arc-shaped and the arc shape matches the end shape of the toothless part 6 of the first driving wheel 2. The toothed part 5 of the first driving wheel 2 is meshed with the normal latch of the first driven wheel 4 to drive the first driven wheel 4 to rotate; after the toothed part 5 of the first driving wheel 2 is disengaged from the normal latch of the first driven wheel 4, the end part of the locking latch 19 is attached to the end surface of the toothless part 6 of the first driving wheel 2, and at this time, the toothless part 6 of the first driving wheel 2 can apply a limiting force to the end part of the locking latch 19, so that the first driven wheel 4 cannot rotate continuously under the action of inertia.

The guide rollers comprise a first guide roller 20 and a second guide roller 21, the first guide roller 20 and the second guide roller 21 are tangent, and the printing table 7 is positioned on the same plane with the tangent plane of the first guide roller 20 and the second guide roller 21.

The first driven wheel 4 can drive the first guide roller 20 to rotate, so that the first driven wheel 4 and the first guide roller 20 are kept synchronous, namely when the material conveying roller 1 rotates to feed materials, the first guide roller 20 rotates to feed materials; when the material delivery roller 1 stops feeding, the first guide roller 20 stops rotating along with the material delivery roller. Meanwhile, the first guide roller 20 drives the third driven wheel 23 through the third rotating wheel so as to drive the second guide roller 21 to rotate, so that the second guide roller 21 rotates along with the first guide roller 20, and the rotating directions of the first guide roller 20 and the second guide roller 21 are opposite, thereby ensuring smooth feeding of the guide rollers.

The lower end surface of the printing body 8 is set as a printing surface 9, and the printing body 8 can move downwards until the printing body is pressed on the cloth on the printing table 7 to print and dye the cloth.

The printing body 8 driving mechanism is in transmission connection with the printing body 8. Specifically, the driving mechanism of the printing and dyeing body 8 comprises a second driving wheel 10, a second driven wheel 11 and a transmission rod 12. The second driving wheel 10 is connected with the second driven wheel 11 through a driving wheel 13, and the second driving wheel 10, the driving wheel 13 and the second driven wheel 11 are rotatably arranged on the inner side of the supporting upright post 15. When the second driving wheel 10 rotates in any direction, the driving wheel 13 is engaged with the driving wheel 13 to drive the driving wheel 13 to rotate in the opposite direction, and the driving wheel 13 is engaged with the second driven wheel 11 to enable the second driven wheel 11 and the second driving wheel 10 to rotate in the same direction, and the synchronous linkage is realized, that is, when the second driving wheel 10 rotates, the second driven wheel 11 rotates along with the second driving wheel.

Wherein, fan-shaped gears 14 are coaxially and fixedly arranged on the second driving wheel 10 and the second driven wheel 11, and the shapes of the two fan-shaped gears 14 are matched with the shape of the clamping teeth arranged on the two fan-shaped gears. The transmission rod 12 and the two sector gears 14 are located in the same plane, the transmission rod 12 is located between the two sector gears 14, and clamping teeth matched with the sector gears 14 are arranged on two sides of the transmission rod 12. When the second driving wheel 10 and the second driven wheel 11 rotate synchronously, the two sector gears 14 are alternately meshed with the latch on the transmission rod 12 to drive the transmission rod 12 to reciprocate in the vertical direction. The lower end of the transmission rod 12 is connected with the printing and dyeing body 8, and then the printing and dyeing body 8 can be driven to lift through the lifting of the transmission rod 12, so that the printing and dyeing work of the cloth is completed.

It should be noted that the above-mentioned driving mechanisms for the printing and dyeing body 8 are installed on the inner sides of the two supporting columns 15, that is, both sides of the printing and dyeing body 8 are driven by the driving rod 12, so that the forces on both sides of the printing and dyeing body 8 are balanced during the process of up-and-down movement of the printing and dyeing body 8, and the printing and dyeing effect is prevented from being affected by the inclination of the printing and dyeing body 8 during the process of up-and-down movement.

It should also be noted that, a limiting shaft sleeve 17 for limiting the moving direction of the transmission rod 12 is disposed on the inner side of the support column 15, a limiting hole 18 along the vertical direction is formed in the limiting shaft sleeve 17, the size of the limiting hole 18 is slightly larger than the size of the end face of the transmission rod 12, and the transmission rod 12 passes through the limiting hole 18. The limiting shaft sleeve 17 has a horizontal limiting effect on the transmission rod 12, so that the transmission rod 12 can only move in the vertical direction.

Wherein, the second driving wheel 10 is connected with the first driven wheel 4 through a transmission belt in a transmission way. Namely, when the first driven wheel 4 rotates, the first driven wheel 4 drives the second driving wheel 10 to rotate through the transmission belt, so that the second driving wheel 10 and the first driven wheel 4 have synchronous linkage, and the whole printing and dyeing equipment has linkage by combining the synchronous linkage between the second driving wheel 10 and the second driven wheel 11 and between the sector gear 14 and the transmission rod 12.

When first action wheel 2 drives first from the rotatory time of driving wheel 4, it is rotatory that first from driving wheel 4 drives defeated material roller 1, simultaneously, first from driving wheel 4 drives second action wheel 10 rotation through driving belt, and second action wheel 10 drives the second again through drive wheel 13 and follows driving wheel 11 rotation, second action wheel 10 and second drive sector gear 14 rotation respectively from driving wheel 11, two sector gear 14 drive transfer line 12 along vertical direction reciprocating motion again jointly to drive printing and dyeing body 8 and go up and down, accomplish the printing and dyeing to the surface fabric.

In addition to the above embodiments, the present invention may have other embodiments; all technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope of the claims of the present invention.
