Description

Technical Field

[0001] This utility model relates to the field of zipper production feeding technology, specifically to a feeding device for zipper production. Background Technology

[0002] Zippers are widely used accessories in the manufacturing industries of clothing, bags, and footwear. In the assembly line production of zippers, the feeding device is a key piece of equipment to ensure the accurate delivery of materials. Its performance directly affects the production efficiency and quality of zippers. With the development of automated production, the demand for intelligent and efficient zipper production lines is gradually increasing. This requires the feeding device to deliver various raw materials required for zipper production, such as zipper teeth, zipper belts, and zipper heads, more accurately, stably, and efficiently.

[0003] Traditional feeding devices in processes such as zipper injection molding can usually only transport and position two separate zipper belts, which can easily introduce positioning deviations in the zipper belts and make it difficult to guarantee the subsequent processing accuracy of the transported materials.

[0004] In existing zipper production feeding devices, each of the two conveyor rollers is equipped with a drive motor. When a temporary jam occurs, the chain can be suddenly tightened due to the delay in the motor's opening and closing, causing the chain to break. This interrupts the feeding process. Furthermore, when the chain is wound around the take-up roller, it is easy for the chain to fail to fully unfold. Ultimately, during feeding, the chain is not fully unfolded, resulting in defects in the finished product. Utility Model Content

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0017] The present invention will be further described below with reference to the embodiments.

[0018] Example 1: Reference Figure 1-3This first embodiment of the present invention discloses a feeding device for zipper production, comprising: a rectangular loading block 1 and a protective frame 2. The protective frame 2 is fixedly installed on the vertical surface of the rectangular loading block 1. A round rod 3 is provided through the vertical surface of the rectangular loading block 1. A gear sleeve 4 is provided through the rod body of the round rod 3. A pair of symmetrical rotating rods 5 are rotatably connected to the vertical surface of the rectangular loading block 1. A first gear column 6 that is penetrated is fixedly connected to the rod body of the pair of rotating rods 5. The pair of first gear columns 6 are both meshed with the same gear sleeve 4. The pair of rotating rods 5 are both fixedly connected to the same positioning plate 7. A conveying sleeve is installed on the rod body of the pair of rotating rods 5.

[0019] A pair of first gear spurs 6 are meshed with a second gear spur 8. A loading rod is rotatably connected to the vertical surface of a rectangular loading block 1. The second gear spur 8, which is penetrated, is fixedly installed on the loading rod.

[0020] A conveying frame 9 is installed on each of the two loading rods. An arc-shaped positioning block 10 is provided on each of the two loading rods. A positioning rod 11 is also provided through the vertical surface of the arc-shaped positioning block 10. The end of the positioning rod 11 away from the arc-shaped positioning block 10 is connected to the vertical surface of the rectangular loading block 1.

[0021] When the device is in use, the drive motor is connected to the end of the round rod 3 away from the gear sleeve 4. When the drive motor is in use, the round rod 3 will rotate. Since the gear sleeve 4 and the pair of first gear columns 6 are meshed, when the gear sleeve 4 rotates, the pair of first gear columns 6 will rotate in the same direction. Since the pair of first gear columns 6 are meshed with the second gear column 8, the loading rod is rotatably connected to the vertical surface of the rectangular loading block 1. The second gear column 8 that is penetrated is fixedly installed on the body of the loading rod, and the loading rod is rotatably connected to the arc-shaped positioning block 10. Therefore, when the pair of first gear columns 6 rotate, the pair of second gear columns 8 will rotate in the direction of the first gear column 6. The rotating rod 5 and the loading rod are respectively equipped with the conveyor sleeve and the conveyor frame 9, thereby realizing the conveying of the chain belt through the pair of rotating rods 5 and the pair of loading rods.

[0022] Example 2: Reference Figure 1 , 4 5 is the second embodiment of this utility model. The difference between this embodiment and the first embodiment is that: a rectangular mounting plate is provided on the lower surface of the protective frame 2, a rectangular outer shell 12 is provided through the upper surface of the rectangular mounting plate, and a pair of mounting frames 13 are provided on the vertical surface inside the rectangular outer shell 12. Both of the mounting frames 13 are connected to the same arc-shaped base plate 14.

[0023] A pair of symmetrical Z-shaped mounting plates are installed on the vertical surface of the arc-shaped base plate 14. An arc-shaped block 15 is fixedly installed on the end of the pair of Z-shaped mounting plates away from the mounting frame 13. An expansion rod 16 is provided on the lower surface of the arc-shaped block 15.

[0024] An arc-shaped outer frame 17 is provided on the upper surface of the arc-shaped block 15. A heating resistance wire 18 is also provided inside the arc-shaped outer frame 17. A pressing block 19 is provided on the upper surface of the arc-shaped outer frame 17. A pair of symmetrical rectangular strips are provided on the upper surface of the pressing block 19. Arc-shaped mounting rods 20 are provided through the vertical surfaces of the rectangular strips. The pair of arc-shaped mounting rods 20 are rotatably connected to the same pressing roller 21.

[0025] The electric heating resistance wire 18 is a resistive element that uses the thermal effect of electric current to convert electrical energy into heat energy. It is widely used in heating equipment, industrial production, household appliances and other fields. The core principle of the electric heating resistance wire is the Joule-Lenz law: when an electric current passes through a conductor, the conductor generates heat due to the existence of resistance. The heat formula is Q=I2Rt (where Q is heat, I is current, R is resistance and t is time).

[0026] When the device is in use, the chain will first pass through the expanding rod 16, and the arc-shaped surface of the arc block 15 will contact the chain. At this time, the chain is being pulled. When the chain is pulled, the originally wound chain will be gradually unwound due to the arc-shaped surface of the arc block 15. The chain will then pass through the arc-shaped outer frame 17. Because the arc-shaped outer frame 17 is equipped with a heating resistance wire 18, and because the arc-shaped outer frame 17 itself is made of a heat-conducting material, the chain will be heated when it passes through the arc-shaped outer frame 17. The heated chain will then contact the pressing block 19 with a gradually expanding cross-section. A pair of symmetrical rectangular bars are provided on the upper surface of the pressing block 19. Arc-shaped mounting rods 20 are provided through the vertical surfaces of the rectangular bars. The pair of arc-shaped mounting rods 20 are rotatably connected to the same pressing roller 21. When the chain passes through the pressing roller 21, the pressing roller 21 will also play a shaping role for the chain.

[0027] The remaining structure is the same as that in Example 1.

[0028] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
