Description

Technical Field

[0001] The invention relates to the field of zipper manufacturing equipment, and more specifically to an automatic feeding device for zipper heads. Background Art

[0002] The zipper head mainly includes a slider body and a pull tab, wherein the slider body includes an upper wing, a lower wing and a chain column, the upper wing and the lower wing are connected by the chain column to form a Y-shaped channel for the chain teeth to pass through, and a connection hole is provided at the bottom of the pull tab to be connected to the top of the upper wing. After the slider body is assembled with the pull tab, horse hook or spring, some manufacturers, in order to meet customer needs, for example, inject rubber or silicone on the rear end of the pull tab of the alloy YG head, which can increase the friction between the pull tab and the consumer and facilitate the consumer's pulling and closing; on the other hand, it can be customized according to consumer needs to improve the aesthetics of the zipper head.

[0003] The traditional production process of this type of glue-injected zipper head is as follows: first, manually place the zipper heads to be injected with glue one by one into the core of the injection mold; then push the injection mold to the bottom of the injection molding machine head for injection; then pull out the injection mold after injection, and manually demold the multiple glue-injected zipper heads bonded to the same central glue stick. During demolding, the glue-injected zipper heads need to be separated from the core of the injection mold one by one; finally, manually cut each glue-injected zipper head from the central glue stick. Among them, manually placing the zipper heads with pull tabs one by one into the core of the injection mold not only requires a large workload, but also has extremely low efficiency, which is difficult to meet the needs of mass production of glue-injected pull heads. To this end, we provide an automatic feeding device for zipper heads. Summary of the invention

[0004] The invention provides an automatic feeding device for zipper heads, so as to solve the shortcomings of the existing method of manually placing zipper heads with pull tabs one by one into a mold core of an injection lower mold, which results in large workload, extremely low efficiency and difficulty in meeting the needs of mass production of injection-molded pull heads.

[0005] The present invention adopts the following technical solution:

[0006] The zipper head automatic feeding device comprises a zipper head feeding track, a zipper head supporting platform, an elastic material stopping mechanism, a zipper head clamping mechanism and a radial moving mechanism, wherein the zipper head feeding track is inclined, the zipper head supporting platform is supported by the inclined end of the zipper head feeding track, a zipper head guide groove is provided on the top surface of the zipper head supporting platform, and the two side walls of the zipper head guide groove are symmetrically provided with an elastic material stopping mechanism supported on the side surface of the front end of the slider, and the zipper head clamping mechanism for clamping the zipper head from both sides of the wing plate on the zipper head is provided above the slider guide groove corresponding to the elastic material stopping mechanism, and the radial moving mechanism is connected to the zipper head clamping mechanism to drive the zipper head clamping mechanism to clamp the zipper head and move it to the corresponding zipper head core mold.

[0007] Specifically, the radial moving mechanism includes a radial moving track, a radial moving slider and a radial driving cylinder. The radial moving track is fixed on a bracket arranged beside the zipper head unloading track. The radial moving track is parallel to the central axis of the slider guide groove. The radial moving slider can be slidably arranged on the radial moving track. The radial driving cylinder is fixed to the rear end of the radial moving track and is connected to the radial moving slider.

[0008] Preferably, the zipper head clamping mechanism is a pneumatic clamping jaw, and the pneumatic clamping jaw is fixedly connected to the radially movable slider via a connecting plate.

[0009] Furthermore, each of the elastic material blocking mechanisms includes a material blocking plate, a compression spring and a connecting screw. The zipper head supporting platform is provided with a material blocking plate slide groove that is vertically connected to the zipper head guide groove. The material blocking plate can be slidably arranged on the material blocking plate slide groove. One end of the material blocking plate protrudes from the side wall of the zipper head guide groove, and the other end is provided with a downwardly extending connecting portion, which has a screw connecting hole that is connected to the side wall of the zipper head supporting platform. The connecting screw passes through the screw connecting hole and is spirally connected to the side wall of the zipper head supporting platform, and the compression spring is sleeved on the connecting screw outside the screw connecting hole.

[0010] Furthermore, an arc-shaped guide portion is provided at one end of the material blocking plate protruding from the side wall of the zipper head guide groove.

[0011] Furthermore, the top surfaces of the two side walls of the zipper head guide groove are lower than the top surface of the upper wing of the zipper head, so that the upper wing of the zipper head has enough longitudinal height to be clamped by the zipper head clamping mechanism.

[0012] Furthermore, the width of the zipper head guide groove is slightly greater than the maximum width of the zipper head lower wing.

[0013] From the above description of the structure of the present invention, it can be seen that compared with the prior art, the present invention has the following advantages:

[0014] 1. The automatic feeding device of the present invention comprises a zipper head feeding track, a zipper head supporting platform, an elastic material blocking mechanism, a zipper head clamping mechanism and a radial moving mechanism. The zipper head slides from the zipper head feeding track to the zipper head supporting platform, and both sides of the front end of the slider body are blocked by the elastic material blocking mechanism, and then clamped by the zipper head clamping mechanism. Finally, the zipper head clamping mechanism is pushed by the radial moving mechanism to overcome the elastic force of the elastic material blocking mechanism and push it to the corresponding slider core mold. The loading is completed when the zipper head clamping mechanism is released. The present invention is extremely suitable for the feeding of zipper heads with pull tabs fixed in parallel to the slider body. The feeding efficiency is greatly improved, which can meet the mass production needs of zipper heads.

[0015] 2. The automatic feeding device of the present invention has elastic material blocking mechanisms symmetrically arranged on both sides of the zipper head guide groove of the zipper head supporting platform. The two elastic material blocking mechanisms not only play a role in dividing the materials, but also play a role in correcting and guiding the zipper head, thereby preventing the zipper head from deviating and affecting the clamping of the zipper head clamping mechanism, thereby ensuring the accuracy of the zipper head clamping and feeding.

[0023] Reference Figure 2 The width of the zipper head guide groove 200 is slightly larger than the maximum width of the lower wing of the zipper head, and the top surfaces of the two side walls of the zipper head guide groove 200 are lower than the top surface of the upper wing of the zipper head, so that the upper wing of the zipper head has sufficient longitudinal height for the zipper head clamping mechanism 40 to clamp.

[0024] Reference Figure 2 The radial moving mechanism 50 includes a radial moving track 51, a radial moving slider 52 and a radial driving cylinder 53. The radial moving track 51 is fixed on a bracket 11 arranged beside the zipper head unloading track 10. The radial moving track 51 is parallel to the central axis of the slider guide groove 200.
