Description

Technical Field

[0001] This utility model belongs to the field of glue spraying technology for back-end gluing machines, specifically, it relates to a glue spraying mechanism for back-end gluing machines. Background Technology

[0002] Currently, in the shoe production process, one step is to attach the upper. After the upper is attached, the surrounding shoe surface needs to be rolled up and squeezed to make it stick firmly to the upper. The heel counter is widely used in shoe manufacturing workshops due to its high efficiency and reliability. During the use of the heel counter, it is generally necessary to apply glue to the sole surface through a glue coating mechanism.

[0003] When applying glue, the glue applicator typically moves the glue nozzle continuously along the outer side of the shoe upper to ensure even application of glue. However, this method has a significant drawback: after application, some glue continues to flow out of the glue tube. This not only wastes glue but also causes it to drip onto the frame, affecting its subsequent performance.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies.

[0005] Therefore, in order to solve the above problems, this utility model provides a glue spraying mechanism for a back-end gluing machine. Utility Model Content

[0006] To overcome the aforementioned technical problems, the purpose of this utility model is to provide a glue spraying mechanism for a backstrap machine. The sliding seat on the guide rail drives the glue spraying head to move. Glue is injected into the spraying head through a glue delivery tube and then sprayed onto the shoe. When the spraying head reaches its maximum right end, the first and fourth clamping blocks work together to clamp the glue delivery tube, thus blocking it and preventing further glue flow. When the spraying head reaches its maximum left end, the second and third clamping blocks work together to clamp the glue delivery tube, again blocking it and preventing further glue flow.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] A gluing mechanism for a finishing machine includes a finishing machine body. Two sets of symmetrically distributed guide rails are mounted on the finishing machine body. A sliding seat is slidably connected to each guide rail. A first electric telescopic rod is mounted at the bottom end of each sliding seat. A connecting seat is mounted at the output end of the first electric telescopic rod. A gluing head is mounted at the bottom end of the connecting seat. A glue delivery pipe is connected to one side of the gluing head. A first clamping block and a second clamping block are fixedly mounted on one side of the connecting seat. Two sets of symmetrically distributed first vertical plates and second vertical plates are fixedly mounted on the finishing machine body. A third clamping block is fixedly mounted on one side of each first vertical plate. A fourth clamping block is fixedly installed on one side of the second vertical plate. The sliding seat moves the glue spraying head by sliding on the guide rail. Glue is injected into the glue spraying head through the glue delivery tube and then sprayed onto the shoe. When the glue spraying head moves to the maximum value at the right end, the glue delivery tube can be clamped by the cooperation of the first and fourth clamping blocks, thereby blocking the glue delivery tube and preventing the glue from flowing out. When the glue spraying head moves to the maximum value at the left end, the glue delivery tube can be clamped by the cooperation of the second and third clamping blocks, thereby blocking the glue delivery tube and preventing the glue from flowing out.

[0009] Furthermore, the rear end of the machine is equipped with a shoe holder.

[0010] Furthermore, the two sets of sliding seats are connected by a connecting rod, and a telescopic cylinder is also installed on the back-end machine body, with the output end of the telescopic cylinder connected to the connecting rod.

[0011] Furthermore, a glue box is installed at the top of the backing machine body, and a second electric telescopic rod is installed at the top of the inside of the glue box. A piston plate is installed at the output end of the second electric telescopic rod, and the piston plate is slidably connected to the inside of the glue box.

[0012] Furthermore, the glue delivery tube is connected to the glue box.

[0013] Furthermore, the first clamping block and the second clamping block are staggered in the vertical direction on one side of the connecting seat.

[0014] Furthermore, the third clamping block and the second clamping block are arranged at the same height.

[0015] Furthermore, the first clamping block and the fourth clamping block are arranged at the same height.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In this invention, shoes are placed on a base, and then the first electric telescopic rod is activated to adjust the height of the glue nozzle so that its outlet matches the shoe. Then, the second electric telescopic rod is activated, causing the piston plate to descend and pressurize the glue in the glue tank, allowing the glue to be output through the glue delivery pipe and sprayed onto the shoe from the nozzle. A telescopic cylinder moves a connecting rod, which in turn moves a sliding seat, which in turn moves the glue nozzle. When the nozzle reaches its maximum right position, the glue spraying on one set of shoes is complete. At this point, the first and fourth clamping blocks clamp the glue delivery pipe, blocking it and preventing further glue flow. Then, another set of shoes is placed on the base, and the telescopic cylinder retracts, causing the sliding seat to move back and the glue nozzle to move back. When the nozzle reaches its maximum left position, the second and third clamping blocks clamp the glue delivery pipe, blocking it and preventing further glue flow. Attached Figure Description

[0025] The utility model will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0026] Please see Figure 1-4 According to an embodiment of the present invention, a back-end gluing mechanism includes a back-end gluing machine body 1. Two sets of symmetrically distributed guide rails 3 are mounted on the back-end gluing machine body 1. A sliding seat 4 is slidably connected to the guide rails 3. A first electric telescopic rod 7 is mounted at the bottom end of the sliding seat 4. A connecting seat 8 is mounted at the output end of the first electric telescopic rod 7. A glue-spraying head 9 is mounted at the bottom end of the connecting seat 8. A glue-feeding pipe 13 is connected to one side of the glue-spraying head 9. A first clamping block 14 and a second clamping block 15 are fixedly mounted on one side of the connecting seat 8. Two sets of symmetrically distributed first vertical plates 16 and second vertical plates 18 are fixedly mounted on the back-end gluing machine body 1. A third clamping block 17 is fixedly mounted on one side of the first vertical plate 16. A fourth clamping block 19 is fixedly installed on one side of the plate 18. The sliding seat 4 moves the glue spraying head 9 by sliding on the guide rail 3. Glue is injected into the glue spraying head 9 through the glue delivery tube 13 and then sprayed onto the shoe. When the glue spraying head 9 moves to the maximum value at the right end, the glue delivery tube 13 is clamped by the cooperation of the first clamping block 14 and the fourth clamping block 19, thereby blocking the glue delivery tube 13 and preventing the glue from flowing out. When the glue spraying head 9 moves to the maximum value at the left end, the glue delivery tube 13 is clamped by the cooperation of the second clamping block 15 and the third clamping block 17, thereby blocking the glue delivery tube 13 and preventing the glue from flowing out.

[0027] The rear body 1 is equipped with a shoe holder 2 for placing shoes.

[0028] The two sets of sliding seats 4 are connected by a connecting rod 5. A telescopic cylinder 6 is also installed on the back machine body 1, and the output end of the telescopic cylinder 6 is connected to the connecting rod 5.

[0029] A glue box 10 is installed at the top of the backing machine body 1. A second electric telescopic rod 11 is installed at the top inside the glue box 10. A piston plate 12 is installed at the output end of the second electric telescopic rod 11. The piston plate 12 is slidably connected to the inside of the glue box 10.

[0030] The glue delivery tube 13 is connected to the glue box 10.

[0031] The first clamping block 14 and the second clamping block 15 are staggered in the vertical direction on one side of the connecting seat 8.

[0032] The third clamping block 17 and the second clamping block 15 are arranged at the same height.

[0033] The first clamping block 14 and the fourth clamping block 19 are arranged at the same height.

[0034] The working principle of the glue spraying mechanism of the backstrap machine of this utility model patent is as follows: The shoe is placed on the placement seat 2, and then the first electric telescopic rod 7 is activated. The height of the glue spraying head 9 is adjusted by the first electric telescopic rod 7 so that its outlet matches the shoe. Then the second electric telescopic rod 11 is activated. The second electric telescopic rod 11 drives the piston plate 12 to descend. The piston plate 12 pressurizes the glue in the glue tank 10, so that the glue can be output through the glue delivery pipe 13 and sprayed from the glue spraying head 9 onto the shoe. The telescopic cylinder 6 drives the connecting rod 5 to move, and the connecting rod 5 drives the sliding seat 4 to move. The movement of the sliding seat 4 drives the glue spraying. When the spray nozzle 9 moves to its maximum value on the right, the glue spraying on one set of shoes ends. At this time, the first clamping block 14 and the fourth clamping block 19 work together to clamp the glue delivery tube 13, thus blocking the glue delivery tube 13 and preventing the glue from flowing out. Then, another set of shoes is placed on the placement seat 2. The telescopic cylinder 6 retracts, causing the sliding seat 4 to move back, and the spray nozzle 9 moves back. When the spray nozzle 9 moves to its maximum value on the left, the second clamping block 15 and the third clamping block 17 work together to clamp the glue delivery tube 13, thus blocking the glue delivery tube 13 and preventing the glue from flowing out.

[0035] It should be noted that the back-mounted machine body 1, the telescopic cylinder 6, the first electric telescopic rod 7, and the second electric telescopic rod 11 are existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition, and principle are clear to those skilled in the art, so they will not be described in detail here.
