[0021] Figure 6 This is a schematic diagram of the zipper pull packaging principle. Detailed Implementation

[0022] like Figure 1 As shown, this zipper head sealing machine includes a base 1, a film feeding station 15, and a sealing station. The film feeding station 15 provides a plastic film M, which then enters the sealing station, as shown... Figure 6 As shown, the zipper head L is automatically packaged at the packaging station.

[0023] To achieve automated packaging, two sprockets 2 are installed on the base 1 of the packaging station, such as... Figure 4As shown, two sprockets 2 are wound with chains 3, and several equally spaced hanging pieces 5 are connected to the chains 3. Each hanging piece 5 has a hanging opening 50 for hanging the zipper head (the head L1 of the zipper head L is hung in the hanging opening 50 of the hanging piece 5). The chains 3 are provided with pads 6 and clamps 7 located below the hanging pieces 5. Each hanging piece 5 corresponds to one pad 6 and one clamp 7. The clamp 7 is rotatably set and its upper end abuts against the pad 6 under the action of an elastic element (the elastic element can be a torsion spring or a spring). Once the zipper head L1 is hooked onto the hanging piece 5, the clamping block 7, under the action of the elastic element, acts on the zipper piece L2 of the zipper head L1. This clamping block 7, together with the pad block 6, clamps the zipper piece L2 of the zipper head L, thus ensuring a more stable sealing. Of course, along the feeding direction on the outside of the chain 3, there are sequentially arranged a loading station 10, a film cutting station, and a unloading station 11. The loading station 10 is equipped with a loading opening mechanism that opens the clamping block 7, allowing the zipper head L to be normally mounted onto the hanging piece 5 at the loading station 10. Similarly, the unloading station 11 is equipped with an unloading opening mechanism that opens the clamping block 7, allowing the sealed zipper head L to be removed. Additionally, the film cutting station is equipped with a film cutting mechanism, such as... Figure 1 As shown, the film cutting mechanism includes a film cutting component 8 and a film cutting power source 9 that drives the film cutting component 8 to perform film cutting action.

[0024] The specific working principle of this zipper head sealing machine is as follows: Taking the movement of one of the hanging pieces 5 as an example, the entire sealing process of the zipper head L is explained. First, the hanging piece 5 is at the feeding station 10, and its corresponding clamping block 7 is opened by the feeding part, so the zipper head L can be normally hung on the hanging piece 5. The plastic film M from the film supply station 15 also enters from the feeding station 10. The clamping block 7 in front of the feeding station 10 can clamp the plastic film M with the pad block 6 and move forward with the chain 3. After the zipper head L is hung on the hanging piece 5, it continues to move forward. Since it is no longer affected by the feeding part, the clamping block 7 clamps the zipper piece L2 of the zipper head L due to the elasticity of the elastic element, so the plastic film M is firmly sealed. The zipper piece L2 firmly encloses the zipper head L, and the zipper piece L2 will not wobble. As the chain 3 continues to move, the hanging piece 5 and the zipper head L arrive at the film cutting station. The film cutting component 8 at the film cutting station moves between the pads 6 under the drive of the film cutting power source 9, thus cutting the plastic film M. Then, as the chain 3 continues to move, the hanging piece 5 and the zipper head L arrive at the unloading station 11. At the unloading station 11, the unloading opening component opens the clamping block 7, so that the sealed zipper head L can be removed, thus completing one sealing cycle.

[0025] As described above, at the loading station 10, the clamping block 7 needs to be opened using the loading opening device, and at the unloading station 11, the clamping block 7 needs to be opened using the unloading opening device. The loading opening device can be a cylinder (or hydraulic cylinder). The extension rod of the cylinder, when pressed against the lower end of the clamping block 7, can open the upper end of the clamping block 7. Similarly, the unloading opening device can also be a cylinder (or hydraulic cylinder). The extension rod of the cylinder, when pressed against the lower end of the clamping block 7, can open the upper end of the clamping block 7. Both of these fall within the scope of protection of this invention.

[0026] However, using a cylinder (or hydraulic cylinder) for opening has several problems, such as requiring very precise application and timing, and the high-frequency operation of the cylinder (or hydraulic cylinder) makes it prone to malfunction. Therefore, this invention provides a better solution: such as... Figure 2-5 As shown, the loading opening component is the loading support guide plate 13, and the lower end of the clamping block 7 moves inward under the guidance of the loading support guide plate 13. Figure 5 As shown, since the feeding guide plate 13 can push the lower end of the clamping block 7 inward, the upper end of the clamping block 7 can be opened. This plate-shaped guide structure is more stable and has a lower cost.

[0027] When the guide plate 13 is opened by feeding material, in order to allow the clamping block 7 to close slowly (gradually closing to prevent the upper end of the clamping block 7 from directly hitting the zipper head L), as follows: Figure 5 As shown, the present invention has a feeding closing guide plate 14 in front of the feeding opening guide plate 13. Under the action of the elastic element, the lower end of the clamping block 7 gradually moves outward along the feeding closing guide plate 14. In this way, the upper end of the clamping block 7 gradually moves towards the zipper head L and acts gently on the zipper head L, protecting the zipper head L and the plastic film M.

[0028] Similarly, the unloading opening mechanism also uses the unloading guide plate 12, and the lower end of the clamping block 7 gradually moves inward under the guidance of the unloading guide plate 12. In this way, the upper end of the clamping block 7 gradually opens, and the zipper head L can be removed normally. Likewise, this plate-shaped guiding structure is more stable and has a lower cost.

[0029] The clamping block 7 at the unloading station 11 is in the open state, and the clamping block 7 at the loading station 10 also needs to be in the open state. To maintain the open state of the clamping block 7 from the unloading station 11 to the loading station 10, as follows... Figure 3 and Figure 5 As shown, the loading guide plate 13 of the present invention is located between the loading closing guide plate 14 and the unloading guide plate 12. In this way, the frequency of opening and closing of the clamping block 7 can be minimized, thereby simplifying manufacturing difficulty, reducing manufacturing costs, and extending the life of the elastic element.

[0030] At the loading station 10, to facilitate the loading of the zipper head, the present invention provides a downwardly inclined loading chute 16, with the unloading end of the loading chute 16 close to the hanging piece 5 at the loading station 10. The zipper head L can be placed on the loading chute 16 manually or by other means, and the loading chute 16 will allow the zipper head L to slide down automatically and fall onto the hanging piece 5 at the loading station 10.

[0031] The zipper pull L can be fed manually or mechanically. To achieve automation, such as… Figure 1 As shown, the present invention has a vibrating feeder 17 installed on the base 1, which is connected to the feeding chute 16 for conveying. Through the vibration of the vibrating feeder 17, the zipper head automatically moves upward and enters the feeding chute 16, which allows the zipper head to automatically slide down and fall onto the hanging piece 5 at the feeding station 10.

[0032] To facilitate the installation of mounting plate 5, such as Figure 4 As shown, the present invention has an upper chain seat 41 on the chain 3, and a hanging plate seat 4 is connected to the upper chain seat 41. The hanging plate 5 is connected to the hanging plate seat 4 (when different sizes of zipper heads need to be packaged, only the hanging plate 5 needs to be replaced). Of course, the hanging plate 5 can also be directly connected to the chain axle 30 of the chain 3 or the upper chain seat 41.

[0033] To facilitate the installation of the pad 6, the chain 3 of this invention has a lower chain seat 31. The lower end of the pad 6 is connected to the lower chain seat 31, and the upper end of the pad 6 is connected to the upper chain seat 41. In other words, the upper part of the pad 6 is connected to the upper chain seat 41, while the lower part of the pad 6 is connected to the lower chain seat 31. Due to the connection at both the upper and lower parts, the pad 6 is installed very firmly.

[0034] To facilitate the installation of the clamping block 7, a support 60 is provided on the pad 6, and the middle part of the clamping block 7 is rotatably connected to the support 60 via a pivot. In this way, the clamping block 7 can rotate.

[0035] In order to automatically remove the packaged zipper head, the present invention provides a feeding mechanism 18 at the feeding station 11. The feeding mechanism 18 includes a feeding brush and a feeding power source for driving the feeding brush to move. Driven by the feeding power source, the feeding brush can brush off the packaged zipper head.

[0036] Finally, it's worth mentioning that the film-laying station 15 provides plastic film M. This plastic film M can be folded in half to form a V-shaped sealing film, or it can be formed by laminating two plastic films from two film rolls. Therefore, there can be one or two film-laying stations 15. The plastic film M can be adhesive or non-adhesive. When using non-adhesive plastic film, a heat-sealing station is provided between the loading station 10 and the film-cutting station to ensure better adhesion between the front and back of the plastic film. This heat-sealing station has a heat-sealing mechanism, which includes a heat-sealing head and a heat-sealing power source to drive the heat-sealing head. Before cutting the plastic film M, the heat-sealing head is driven by the heat-sealing power source to heat-seal the plastic film M. After heat-sealing, the plastic film M is cut by the film-cutting component. Therefore, the film-cutting component can be a regular cutter (suitable for pre-heat sealing) or a heating wire (suitable for direct cutting while simultaneously melting and bonding the cut edges of the plastic film).
