Description

Technical Field

[0001] This utility model relates to the field of waste metal resource recycling and environmental protection equipment, specifically to a waste recycling equipment for zipper processing. Background Technology

[0002] With the rapid development of the apparel, bag, and fashion accessory industries, consumers' demand for personalized and high-quality products is constantly increasing. As a crucial accessory for clothing and bags, zippers are widely favored for their diverse designs and excellent practicality. However, most zippers on the market currently use copper teeth, generating a large amount of waste during processing and disassembly. If efficient recycling is not achieved, it not only wastes valuable copper resources but may also have adverse environmental impacts. Therefore, recycling technology for zipper waste, especially metal teeth, is receiving increasing attention, providing a broad market opportunity for the research and development of related equipment.

[0003] In existing technologies, waste zipper recycling production lines mainly employ a primary crushing and secondary airflow separation method. A powerful airflow forces the crushed waste material into a vacuum decompression device, separating the metal zipper teeth from the nylon fabric. Environmentally friendly zipper crushing and separating machines typically incorporate a dust recovery system during the separation process, ensuring no dust leakage and preventing the generation of toxic substances. Furthermore, the separated metal zipper teeth are of good quality and can be directly reused. However, current production often relies on manual feeding. Traditional crushing equipment uses an open-structure design for the feed hopper, which allows zippers to easily fly out of the hopper during crushing due to collisions or airflow, posing a safety hazard.

[0004] Therefore, there is an urgent need to design a waste recycling device for zipper processing to meet current production needs and promote the recycling of copper resources for zipper teeth and the sustainable development of the industry. Utility Model Content

[0005] The purpose of this utility model is to provide a waste recycling equipment for zipper processing. This equipment can process waste zipper waste in each stage of feeding, crushing and sorting, and realize the recycling of metal chain teeth in waste zippers.

Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0020] Example:

[0021] See Figure 1 - Figure 4 This embodiment relates to a waste recycling device for zipper processing, specifically used for efficient crushing and sorting of waste zipper materials, thereby achieving effective separation and recycling of metal zipper teeth and nylon fabric. Specifically, it includes: a machine body 11, which integrates a crushing unit 12 and a sorting unit 13. The crushing unit 12 includes a crushing chamber 14, on which a feed hopper 15 is provided. Two sets of interlocking crushing cylinders 16 are rotatably disposed within the crushing chamber 14, and each crushing cylinder 16 is equipped with a drive unit 17 for driving its rotation.

[0022] Specifically, in this embodiment, a frame 21 is also provided below the machine body 11 to support the crushing unit 12 and the sorting unit 13, ensuring the overall stability of the equipment during operation. The crushing unit 12 includes a sealed crushing chamber 14, and a feeding hopper 15 is provided above the crushing chamber 14. The operator puts the waste zipper material into the feeding hopper 15, and the two sets of interlocking crushing cylinders 16 rotate under the drive of the drive unit 17 to crush the waste material, so that the metal chain teeth disengage from the nylon fabric chain belt. The feeding hopper 15 includes, from top to bottom, a feeding section 22, a tightening section 23, and a connecting section 24.

[0023] The cross-section of the feeding section 22 gradually narrows from top to bottom, allowing the waste zipper to slide in smoothly under the action of gravity. At the same time, the large opening of the feeding section 22 facilitates the dumping of materials.

[0024] The cross-section of the connecting section 24 gradually expands from top to bottom and is connected and fixed to the crushing chamber 14. This not only ensures that the material enters the crushing chamber 14 smoothly, but also allows the material that is knocked away by the rotation of the crushing cylinder 16 to collide with its oblique inner wall, effectively preventing the material from flying out of the crushing chamber 14 and causing injury to personnel (especially when the amount of material fed is small and not continuously fed, the subsequent material cannot effectively fill the feed hopper 15).

[0025] The tightening section 23, located between the feeding section 22 and the connecting section 24, serves as a transitional connection. Specifically, in this embodiment, the tightening section 23 also has a slidably mounted baffle 25, with a handle 26 at one end. The handle 26 drives the baffle 25 to slide, isolating the feeding section 22 and the connecting section 24 from each other. It should be noted that this operation is generally performed when the equipment needs to be stopped due to insufficient material or shift changes.

[0026] The crushed material enters the sorting unit 13 for separation of the metal chain teeth and nylon fabric. Specifically, the sorting unit 13 includes a blower 31 and two sets of discharge hoppers 32. The air outlet pipe 33 of the blower 31 is connected to the crushing chamber 14. The two sets of discharge hoppers 32 are arranged sequentially below the crushing chamber 14 along the direction of the air outlet pipe 33, and a screen 34 is obliquely arranged inside the discharge hopper 32 near the blower 31. In this embodiment, the size of the screen holes of the screen 34 needs to be designed according to the size of the metal chain teeth. The screen holes are circular, and their diameter is not less than the length of the metal chain teeth, so that the metal chain teeth can fall into the discharge hopper 32 through the screen 34. In this embodiment, one end of the screen 34 is connected and fixed to the upper edge near the other set of discharge hoppers 32, and the other end is inclined downward and fixed to the inner wall of the discharge hopper 32. The broken nylon fabric is small in mass and large in volume, and cannot pass through the screen 34. It is blown into another set of discharge hoppers 32 by airflow along the upper surface of the screen 34 to achieve the separation of the metal chain teeth and the nylon fabric.

[0027] In this embodiment, the cross-section of the discharge hopper 32 gradually narrows from top to bottom, facilitating subsequent collection. The crushing cylinder 16 includes a main shaft 41, on which several sets of crushing discs 42 are evenly spaced. A spacer disc 43 is provided between each adjacent set of crushing discs 42. The spacer discs 43 have the same thickness as the crushing discs 42 and are all fixed to the main shaft 41 by a flat key 44. The crushing discs 42 are detachably connected to crushing teeth 45 at equal intervals around their circumference. Compared to the traditional integrated design where a single crushing tooth 45 needs to be replaced entirely after damage, this embodiment uses a detachable connection structure, allowing the crushing teeth 45 to be replaced one by one after wear, facilitating replacement and effectively reducing maintenance costs. Specifically, the crushing teeth 45 are connected to the crushing discs 42 by bolts 46. The crushing discs 42 are circumferentially provided with mounting seats 47, which have threaded holes 48. The crushing teeth 45 have through holes 49, and the bolts 46 pass through the through holes 49 and are screwed into the threaded holes 48 for fixation. During installation, the crushing teeth 45 can be installed on the mounting base 47 of each set of crushing discs 42 first, and then the crushing discs 42 and the spacer discs 43 can be installed on the main shaft 41 in sequence.

[0028] In this embodiment, the drive unit 17 adopts a drive motor 51, which is connected to a set of crushing cylinders 16. The drive motor 51 is connected to the input end of the reducer 52, and the output end of the reducer 52 is connected to the main shaft 41 of the crushing cylinder 16 through a coupling 53. The two sets of crushing cylinders 16 are connected by gear 54 to achieve rotation of the two sets of crushing cylinders 16.

[0029] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
