A zipper head forming device

Abstract

This utility model relates to the technical field of zipper head processing equipment, and discloses a zipper head forming device, including a box body. A support frame is welded to the outside of the box body, and a servo motor is fixedly installed in the middle of the upper end of the support frame. A transmission rod is installed at the output end of the servo motor. A mesh cylinder is provided in the inner cavity of the box body, and the transmission rod is movably connected to the middle of the inner cavity of the mesh cylinder. This utility model's technical solution allows the fixed rod on the mesh cylinder to be inserted into a through hole in a first fixed plate. The transmission rod drives the first fixed plate to rotate, which in turn drives the mesh cylinder to rotate. This causes the zipper head inside the mesh cylinder to rotate within the coating liquid in the box body, thus ensuring sufficient adhesion of the coating liquid to the zipper head. Simultaneously, during the rotation of the mesh cylinder, the fixed plate on the mesh cylinder also rotates, causing the fixed plate to agitate the coating liquid within the box body, creating a turbulent flow state in the coating liquid, further improving the coating adhesion effect of the zipper head.

Description

Technical Field

[0001] This utility model relates to the technical field of zipper head processing equipment, specifically a zipper head forming device. Background Technology

[0002] A zipper consists of teeth, a zipper pull, and top and bottom stops (front and back stops) or locking mechanisms. The teeth are the key component, directly determining the zipper's lateral tensile strength. Generally, a zipper has two straps, each with a row of teeth, arranged alternately. The zipper pull grips the teeth on both sides, and by sliding along the pull tabs, the teeth can engage or disengage. Existing zippers are mainly made of nylon, resin, or metal. An essential step in the manufacturing process of the zipper pull is surface coating, such as painting.

[0003] A search revealed a high-strength plastic zipper head forming device (CN114833021A), comprising: a fixed chamber, a rotating shaft, rotating plates, and movable blocks; the fixed chamber is rotatably connected to the rotating shaft; the rotating plates are evenly distributed around the inner circumference of the fixed chamber; the rotating plates are evenly distributed with through holes; the bottom of the fixed chamber is arc-shaped; an intermediate seat is fixedly installed on the outside of the fixed chamber at one end near the rotating shaft; the intermediate seat is rotatably connected to an intermediate shaft; transmission seats are symmetrically fixedly installed on both sides of the intermediate seat; each transmission seat is rotatably connected to a transmission shaft; a turntable is fixedly installed on the intermediate shaft; and a grooved wheel is fixedly installed on the intermediate shaft.

[0004] The technical solution has at least the following drawbacks: While the invention can rotate the zipper head, thereby increasing the coating speed, the zipper heads are piled up, leading to residue of the coating solution. Furthermore, it is inconvenient to agitate the coating solution to improve the coating efficiency of the zipper head, necessitating improvement. Therefore, we propose a device for forming zipper heads. Utility Model Content

[0005] The purpose of this invention is to provide a zipper head forming device, which solves the problem mentioned in the background art that, because the zipper heads are piled up together, there will be residue of coating liquid, and it is inconvenient to stir the coating liquid to improve the coating efficiency of the zipper head.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a zipper head forming device, comprising a box body, a support frame welded to the outer side of the box body, a servo motor fixedly installed at the upper middle part of the support frame, a transmission rod installed at the output end of the servo motor, a mesh cylinder provided in the inner cavity of the box body, the transmission rod being movably connected to the middle part of the inner cavity of the mesh cylinder, a first fixing plate and a second fixing plate fixedly installed at the lower and upper ends of the transmission rod respectively, through holes being provided on the left and right sides of the first fixing plate and the second fixing plate, fixing rods being fixedly installed on both sides of the lower end of the mesh cylinder, receiving grooves being provided on both sides of the upper end of the fixing rods, limit blocks being provided in the inner cavity of the receiving grooves, and multiple fixing pieces being fixedly installed on the outer side of the lower end of the mesh cylinder, the fixing pieces being distributed in a ring on the outer side of the mesh cylinder.

[0007] By adopting the above technical solution, the fixing rod on the mesh cylinder can be inserted into the through hole on the first fixing plate. Then, the servo motor is turned on, and the servo motor drives the transmission rod to rotate. The transmission rod drives the first fixing plate to rotate, which in turn drives the mesh cylinder to rotate. This causes the zipper head inside the mesh cylinder to rotate in the coating solution inside the box, thus ensuring sufficient adhesion of the coating solution to the zipper head. At the same time, during the rotation of the mesh cylinder, the fixing plate on the mesh cylinder will also rotate, causing the fixing plate to agitate the coating solution inside the box, creating a turbulent state in the coating solution, which further improves the coating adhesion effect of the zipper head. Alternatively, the upper end of the fixing rod can be inserted into the through hole on the second fixing plate, thus separating the mesh cylinder from the coating solution surface inside the box. Then, the servo motor is controlled to rotate, which causes the zipper head inside the mesh cylinder to generate centrifugal force to throw out the accumulated residual coating solution, thus facilitating the removal of the coated zipper head.

[0008] Optionally, the size of the limiting block is adapted to the size of the receiving groove, and the limiting block is movably connected to the receiving groove.

[0009] By adopting the above technical solution and setting the limiting block, the position of the net cylinder can be limited.

[0010] Optionally, lifting rods are fixedly installed on both sides of the net cylinder, and the lifting rods are arranged symmetrically.

[0011] By adopting the above technical solution and setting up the lifting rod, it is convenient to lift the net cylinder.

[0012] Optionally, the size of the fixing rod is adapted to the size of the through hole, and the fixing rod is movably connected to the through hole.

[0013] By adopting the above technical solution and setting through holes, it is convenient to insert the fixing rod into the through holes, thereby achieving the limitation of different positions of the mesh cylinder.

[0014] Optionally, a spring is fixedly installed in the inner cavity of the receiving groove, and the other end of the spring is fixedly connected to the limiting block.

[0015] By adopting the above technical solution and using the spring, the limit block can be easily ejected.

[0016] Optionally, the lower end of the transmission rod is rotatably connected to the lower middle part of the inner cavity of the housing via a bearing.

[0017] By adopting the above technical solution, it is easy to ensure the stability of the transmission rod rotation.

[0018] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0019] This technical solution, through the design of a box, support frame, mesh cylinder, first fixed plate, second fixed plate, fixed rod, limiting block, and fixing plate, allows the fixing rod on the mesh cylinder to be inserted into the through hole on the first fixed plate. Then, the servo motor is activated, driving the transmission rod to rotate, which in turn drives the first fixed plate to rotate, causing the mesh cylinder to rotate as well. This causes the zipper head inside the mesh cylinder to rotate within the coating solution in the box, ensuring sufficient adhesion of the coating solution to the zipper head. Simultaneously, during the rotation of the mesh cylinder, the fixing plate on the mesh cylinder rotates as well, agitating the coating solution within the box and creating a turbulent flow, further improving the coating adhesion effect on the zipper head. Furthermore, the upper end of the fixing rod can be inserted into the through hole on the second fixed plate, separating the mesh cylinder from the coating solution surface inside the box. Then, the servo motor is controlled to rotate, causing the zipper head inside the mesh cylinder to generate centrifugal force, throwing out any accumulated residual coating solution, thus facilitating the removal of the coated zipper head.

[0025] Please see Figure 1-3 This utility model provides a technical solution: a zipper head forming device, including a box body 1, a support frame 11 welded to the outside of the box body 1, a servo motor 12 fixedly installed at the upper middle of the support frame 11, a transmission rod 13 installed at the output end of the servo motor 12, a mesh cylinder 2 provided in the inner cavity of the box body 1, the transmission rod 13 being movably connected to the middle of the inner cavity of the mesh cylinder 2, a first fixing plate 22 and a second fixing plate 23 fixedly installed at the lower and upper ends of the transmission rod 13 respectively, through holes 24 being opened on both the left and right sides of the first fixing plate 22 and the second fixing plate 23, a fixing rod 3 fixedly installed on both sides of the lower end of the mesh cylinder 2, and a receiving groove 4 being opened on both sides of the upper end of the fixing rod 3. The inner cavity is provided with a limiting block 5. Multiple fixing plates 7 are fixedly installed on the lower outer side of the mesh cylinder 2, and the fixing plates 7 are distributed in a ring on the outer side of the mesh cylinder 2. The size of the fixing rod 3 is adapted to the size of the through hole 24, and the fixing rod 3 is movably connected to the through hole 24. The setting of the through hole 24 makes it easy for the fixing rod 3 to be inserted into the through hole 24, thereby limiting the different positions of the mesh cylinder 2. The inner cavity of the receiving groove 4 is fixedly installed with a spring 6, and the other end of the spring 6 is fixedly connected to the limiting block 5. The setting of the spring 6 makes it easy to drive the limiting block 5 to pop out. The lower end of the transmission rod 13 is rotatably connected to the middle of the lower end of the inner cavity of the box 1 through a bearing, which makes it easy to ensure the stability of the rotation of the transmission rod 13.

[0026] The size of the limiting block 5 is adapted to the size of the receiving groove 4, and the limiting block 5 is movably connected to the receiving groove 4. By setting the limiting block 5, the position of the mesh cylinder 2 can be limited.

[0027] Lifting rods 21 are fixedly installed on both sides of the net cylinder 2, and the lifting rods 21 are symmetrically arranged. The lifting rods 21 facilitate the lifting of the net cylinder 2.

[0028] During the molding process, the zipper head to be coated is first poured into the mesh cylinder 2. Then, the mesh cylinder 2 is moved downwards, so that the fixing rod 3 on the mesh cylinder 2 is inserted into the through hole 24 on the first fixing plate 22. Then, the servo motor 12 is turned on, and the servo motor 12 drives the transmission rod 13 to rotate. The transmission rod 13 drives the first fixing plate 22 to rotate, which in turn drives the mesh cylinder 2 to rotate. This causes the zipper head in the mesh cylinder 2 to rotate in the coating liquid in the box 1, thus ensuring the full adhesion of the coating liquid to the zipper head. At the same time, during the rotation of the mesh cylinder 2, the fixing rod 3 on the mesh cylinder 2... The fixed plate 7 will rotate, causing it to agitate the coating solution inside the box 1, creating a turbulent flow and further improving the coating adhesion effect of the zipper head. After the coating is completed, the lifting rod 21 is pulled upwards, causing the upper end of the fixed rod 3 to engage with the through hole 24 on the second fixed plate 23, thereby separating the mesh cylinder 2 from the coating solution surface inside the box 1. Then, the servo motor 12 is controlled to rotate, thereby driving the zipper head inside the mesh cylinder 2 to generate centrifugal force to throw out the accumulated residual coating solution, thus facilitating the removal of the coated zipper head.
