Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The embodiment of the application provides a material shearing mechanism and a feeding machine, which can solve the problems that in the related art, the shearing track and the speed are difficult to control, so that the material drop forming quality is uneven and the efficiency is low.

In one aspect, referring to fig. 1, 2, 3, 8, 12 and 13, the material shearing mechanism comprises:

a trimming arm assembly comprising a first trimming arm 14 and a second trimming arm 15;

scissors arm axle subassembly 12, scissors arm axle subassembly 12 includes first scissors arm axle 111 and second scissors arm axle 112, second scissors arm axle 112 interval sets up among first scissors arm axle 111, just the center pin coincidence of first scissors arm axle 111 and second scissors arm axle 112, first scissors arm axle 111 with first material shearing arm 14 fixed connection, second scissors arm axle 112 with second material shearing arm 15 fixed connection, first scissors arm axle 111 accessible rotation drives first material shearing arm 14 moves, second scissors arm axle 112 accessible rotation drives second material shearing arm 15 moves.

Two motors 11, all be equipped with drive mechanism 13 on every motor 11, two motors 11 pass through respectively drive mechanism 13 first scissors arm axle 111 rotates with second scissors arm axle 112.

Specifically, the movement of the first scissor arm 14 and the second scissor arm 15 means a movement (opening) that overlaps with or separates from each other with the central axis of the first scissor arm shaft 111 and the second scissor arm shaft 112 as an axis. The opening and the coincidence of the two scissors are controlled similarly to the movement track of the daily scissors.

It should be noted that, since the first material shearing arm 14 and the second material shearing arm 15 of the material shearing arm assembly are driven by different motors 11, the shearing frequency and the shearing position can be precisely changed to achieve high yield by adjusting the rotation speed and the rotation time of each motor, respectively, or the time for which the first material shearing arm 14 and the second material shearing arm 15 stay in the open state is changed to sufficiently cool the shearing blade to prolong the service life. The shearing position can be changed by adjusting the rotating speed of the motor 11, so that the overlapped position of the first shearing arm 14 and the second shearing arm 15 can be changed.

In some embodiments, referring to fig. 8, a height adjustment device 16 is disposed on the first scissor-arm shaft 111, and the height adjustment device 16 includes an adjustment screw 161 connected to the first scissor-arm shaft 111 and a locking bolt 162 disposed at a side of the first scissor-arm shaft 111. The adjusting screw 161 is connected to the first scissor arm shaft 111 through the bracket 163, the height of the first scissor arm 14 can be adjusted by adjusting the height of the first scissor arm shaft 111, and the bracket 163 and the first scissor arm shaft 111 are locked by the locking bolt 162 arranged on the bracket 163 to prevent the first scissor arm shaft 111 from moving, so that the heights of the first scissor arm shaft 111 and the first scissor arm 14 fixedly connected thereto are fixed. The height of the second scissor arm shaft 112 can be adjusted to change the size of the upper gap and the lower gap of the scissor blades on the two scissor arms when the scissor blades are overlapped, the size of the gap is not too large or too small, and the adjustment is complex. The height adjusting device 16 is added to facilitate on-site debugging. That is, the adjusting screw 161 is connected to the bracket 163, the first scissor-arm shaft 111 is connected to one side of the bracket 163, and the adjusting screw 161 is indirectly connected to the first scissor-arm shaft 111. But not directly connected to the first scissor-arm shaft 111 due to the height adjustment means 16. Which via the connecting bracket 163 drives the above-mentioned series of components connected to the bracket 163, including the motor 11, the cylinder 2 and the trimming arm assembly and the subsequent additional components. Thus, when the height is adjusted, the components connected with the height can be raised or lowered along with the adjustment.

It is worth to say that, the feeder also includes the cylinder 2, and it is connected with two motors 11 are fixed, cylinder 2 can be through stretching out and drawing back and forth drive motor 11 and last drive mechanism 13 back-and-forth movement. Forward in this context is directed towards the position when the first and second scissor arms 14, 15 are coincident and backward is directed away from the position when the first and second scissor arms 14, 15 are coincident. The left and right are determined relative to the front and back, and the transverse direction passing through the material shearing mechanism 1 is the left and right direction.

It can be understood that, as shown in fig. 8, the cylinder 2 can be connected and fixed with the motors 11 and the transmission mechanism 13 on each motor 11 through a mounting bracket, and the mounting bracket is sleeved on the upper and lower parallel cylindrical shafts 21. The mounting frame can move back and forth along the parallel cylindrical shaft 21 under the pushing of the cylinder 2. Forward is close to the cutting position and backward is far from the cutting position.

Preferably, the transmission mechanism 13 includes a connecting rod 131 and a connecting block 132 connected to the motor 11. The motor 11 drives the link 131 to move, and the link 131 drives the connecting block 132 to move so as to drive the scissor arm shaft assembly 12 to move.

Specifically, as shown in fig. 8, the material shearing mechanism 1 further includes: the supporting block 9 is arranged between the cylinder 2 and the scissor arm shaft assembly 12, the supporting block 9 is generally trapezoidal, two ends of the supporting block 9 are inclined planes, and the middle of the supporting block is protruded in the direction away from the scissor arm shaft assembly 12; the positive and negative tooth screw rod 6 is arranged between the supporting block 9 and the cylinder 2 at intervals, and the positive and negative tooth screw rod 6 transversely penetrates through the whole material shearing mechanism 1 from left to right; two sliders 5, it wears to establish on positive and negative tooth lead screw 6, just slider 5 can follow positive and negative tooth lead screw 6 horizontal slip, every slider 5 with the face that the supporting shoe 9 is relative all be equipped with can with the binding face of laminating mutually on the inclined plane of supporting shoe 9. Here, the surface of the support block 9 on the side close to the cylinder 2 includes: the inclined surfaces on both sides and the plane surface of the middle bulge, so that the whole body is approximately in a trapezoid shape. This also causes the cylinder 2 to be more protruded when the two sliders 5 are moved toward both sides of the supporting block 9, respectively, and the protruded amount of the cylinder 2 becomes smaller when the two sliders 5 are moved toward the vicinity of the center line of the supporting block 9. The supporting blocks 9 are symmetrically arranged at two sides, so that the central lines of the supporting blocks are always positioned at the left middle position and the right middle position of the material shearing mechanism. When the positive and negative teeth screw rod 6 is adjusted manually, the positive and negative teeth screw rod 6 is arranged transversely, so the two slide blocks 5 can be separated from each other towards two sides on the positive and negative teeth screw rod 6 or approach each other towards the central line of the supporting block 9 under the control of the positive and negative teeth screw rod 6.

It should be understood that the support block 9 is not limited to a trapezoidal shape as long as it is constructed in a symmetrical arrangement and a middle protrusion, etc., which meet the above requirements in terms of structural shape.

When the cylinder 2 works, the positive and negative tooth screw rods 6 only play a role in adjusting the extension amount of the cylinder 2. When the cylinder 2 is not yet extended, the cylinder 2 cannot press the slider 5 through the mounting. The two sliders 5 are now separated from the support block 9. When the cylinder 2 extends out, forward pressure is applied to the two sliders 5, so that the binding surfaces of the two sliders 5 and the inclined surface of the supporting block 9 are in a binding state, and the screw rod 6 with the positive and negative teeth can play a role in adjustment. The subsequent regulation is divided into two regulation cases:

case 1: when the positive and negative teeth screw rod 6 is adjusted to move the slide block 5 to the directions of both sides of the supporting block 9, the cylinder 2 increases the extension amount thereof and drives the two motors 11 and the respective transmission mechanisms 13 to move forwards. Because the motor 11 drives the scissor arm shaft assembly 12 to rotate through the driving connecting rod 131 and the connecting block 132 so as to open or overlap the scissor arms. Once motor 11 and transmission 13 move forward, the range of rearward movement of connecting block 132 is reduced, and the range of rotation of scissor arm shaft assembly 12 is correspondingly changed. The maximum value at which the two shearing arms can be driven to open is reduced.

Case 2: on the contrary, if the two sliders 5 are moved back to be close to each other to the vicinity of the center line of the supporting block 9, and the sliders 5 are partially moved to the position where the supporting block 9 protrudes to displace the sliders 5 backward, the extending amount of the cylinder 2 under the action of the sliders 5 is reduced and the motor 11 and other components are driven to displace backward, which increases the maximum opening amount of the shearing arm. Of course, the active control cylinder 2 reduces the extension amount and even retracts, and the maximum opening amount of the material shearing arm can be increased, and the principle is the same.

Preferably, as shown in fig. 8, the first and second trimming arms 14 and 15 are provided with front arms of scissors. Each scissors forearm is provided with a scissors blade and is provided with a kidney-shaped groove. The waist-shaped groove can be adjusted to assist the positive and negative teeth screw rod 6 to adjust the centering and overlapping amount of the shear blade of the material shearing arm (the overlapping amount is generally controlled to be 1.6-2.1 mm).

It is worth mentioning that the cylinder 2 can also function as a power-off protection. When the motor 11 is powered off emergently, the air cylinder can retract automatically. The first material shearing arm 14 and the second material shearing arm 15 are retracted by the cylinder 2 to drive the connecting rod 131 of the transmission mechanism 13 to retract a sufficient distance, so that the connecting block 132 pulls the first material shearing arm 14 and the second material shearing arm 15 back to the opened positions, thereby achieving the purpose of emergency protection.

In some embodiments, referring to fig. 8 and 10, the scissor blades may be arranged in one or two groups, each group including two scissor blades disposed on the first and second scissor arms 14 and 15, respectively. Fig. 8 is a schematic view of the scissors equipped with two sets of blades. If only one pair of scissors blades is assembled, only one pair of scissors blades which are oppositely arranged needs to be reduced.

Preferably, a material supporting assembly is arranged below the material shearing arm assembly, and comprises a fixing plate 17, wherein the fixing plate 17 is generally arranged below the second material shearing arm 15 for convenient adjustment, but may be arranged below the first material shearing arm 14 in some embodiments. A group of striker plates 18 are arranged on the inner sides of the fixing plates 17. The inner side refers to the side close to the superposition of the two cut materials. The material supporting component is used for supporting material drops, so that the shearing of the scissors component is facilitated. The material supporting component is mainly used for supporting the dropping materials below the material supporting component during shearing so as to facilitate shearing.

It should be noted that when two groups of shear blades are assembled (two shear blades are provided on one side of two shear arms, and the shear blades are provided corresponding to the shear blades of the other shear arm), the fixing plate 17 is also provided with two corresponding shear blades. Each fixed plate 17 has the same structure and is provided with a material baffle 18, but each fixed plate 17 corresponds to one group of shear blades.

Preferably, as shown in fig. 8 and 9, the first material shearing arm 14 and the second material shearing arm 15 are provided with a shearing blade for shearing the sheared materials, and a water spraying assembly is arranged below the opening position of the shearing blade. The water spray assembly includes: a connecting plate connected with the iron pan 43, and a water spraying device 19 arranged below the shear blade, wherein the water spraying device 19 sprays cooling liquid to the shear blade with high temperature, and the cooling liquid is saponification water or diluted cooling liquid.

The material refining mechanism 3, the frame component 4, the material punching mechanism 8 and the hanger assembly 7. The material mixing mechanism 3 is used for shaking the dripped materials uniformly, the material punching mechanism 8 is used for punching the shaken dripped materials, and finally the dripped materials fall to a material shearing area of the material shearing mechanism 1 through a dripping bowl under the action of gravity and are sheared into proper dripped materials.

The material shearing mechanism 1 comprises any one of the schemes described above.

Referring to fig. 4, the feeding machine middle frame assembly 4 provided by the present application includes a transportation frame assembly 41 and a feeding channel 42 vertically arranged on the transportation frame assembly 41, an iron pan 43 is arranged on the side surface of the feeding channel 42, a through hole communicated with the iron pan 43 is formed in the upper and lower parts of the iron pan 43, and a bowl supporting plate 44 for supporting a bowl is arranged at the through hole of the iron pan 43. The transportation frame assembly 41 is used for supporting the refining mechanism 3 and the shearing mechanism 1, and the feeding channel 42 is arranged at the top end of the transportation frame assembly 41. The material punching mechanism 8 and the material bowl dropping are both carried out in the iron pan 43 to prevent the material from dropping to other places. Therefore, the iron pan 43 and other related equipment are made of refractory materials, and the refractory materials need to be replaced regularly, so that the normal operation of the equipment is ensured.

Specifically, as shown in fig. 7, the refining mechanism 3 of the feeder machine includes an arch assembly 31, the arch assembly 31, a refining device 33 and a cartridge, and one side of the arch assembly 31 is fixedly connected with the feeding channel 42.

The center of curvature of the arcuate assembly 31 is provided with a refining device 33, the refining device 33 being connected to the barrel and being rotatable to maintain the material in the barrel uniform.

It is worth mentioning that, referring to fig. 5 and 6, the material punching mechanism 8 comprises a mounting bracket 81, a material punching arm 82 and a punch 83, the punch 83 is arranged in the iron pan 43 and can squeeze the material drop in the material bowl under control, so that the material drop is left in the air of the material bowl and falls into the shearing range of the material shearing mechanism 1 under the action of self gravity. The root of the punch 83 is provided with a driving component which can drive the punch 83 to move up and down so as to achieve the purpose of material pressing.

Preferably, referring to fig. 11, the feeder provided by the present application further comprises: the hanger assembly 7 includes a support frame 71, and the support frame 71 is supported on the supply passage 42. The support frame 71 is provided with a balance weight arm 72 on one side and a suspender component 73 driven by a motor on the other side, wherein the suspender component can be driven by the motor to rise and fall, so that the suspender component can be used for transporting and drilling passports during component replacement and maintenance, and the balance weight block can be arranged on the balance weight arm 72, so that the stress of the refining mechanism 3 is more reasonable, and the stable operation of the refining mechanism 3 is ensured.

When the glass liquid feeding device works specifically, when a cold machine is started, the machine has a period of preheating time, after the temperature reaches a proper temperature, formal production can be realized, the glass liquid flows into the charging barrel through the material channel, the charging barrel starts to rotate at a constant speed to enable material drops to be uniform and soft, the charging barrel is driven by the lifting device 32 to be lifted and kept at a certain height, and the glass liquid is fed into the material bowl from top to bottom and slowly flows out from the material flowing hole of the material bowl. At this time, the punch 83 moves downwards with acceleration to extrude molten glass, so that more molten glass flows out of the material hole to form the upper part of the material drop; immediately stopping the downward movement of the punch 83 and starting the upward movement, wherein the molten glass at the material flowing hole is elongated and reduced in diameter under the action of gravity, and is cut into a gob by the shear blade; the punch is accelerated upwards to lift the glass flowing out of the material flowing hole into the material flowing hole; the punch 83 is downward at a constant speed, the molten glass flows out from the material flowing hole under the action of gravity, and at the moment, the shearing mechanism 1 is driven by the two motors 11 to perform superposition action on each pair of shearing blades so as to shear the gob. Cycling this process can shear out successive gobs.

In summary, the shearing mechanism and the feeder provided by the embodiment of the application directly control the shearing mechanism by using the motor, and the opening and closing speed of the shear arm is controlled by the rotating speed of the motor, so that the shearing speed is higher than that of the shearing mechanism and the feeder driven by the cylinder. The bottle poking device is driven by the motor to be more stable in operation. Each motor independently controls one shear arm, so that the shearing track and the shearing pause time of the shearing mechanism are controllable, and the shearing quality is improved. Compared with single motor driving, the adjustment is more convenient. The feeder is provided with a cooling device, so that the shearing mechanism is conveniently cooled and the service life of the shearing mechanism is prolonged. In addition, the cylinder 2 is used as a regulating device and an emergency protection device, so that a larger regulating space and a better safety protection function are provided for the feeding machine and the material shearing mechanism 1.
