[0001] This utility model relates to the field of spandex filament cutting and shredding technology, and more specifically, to a spandex filament cutting and shredding device. Background Technology

[0002] Spandex is an elastic fiber with high elasticity, capable of being stretched 6-7 times its original size and quickly returning to its initial state after the tension is released. Spandex, scientifically known as polyurethane elastic fiber, possesses excellent weather resistance, flexural strength, and abrasion resistance. Spandex spinning methods mainly include dry spinning, wet spinning, melt spinning, and chemical reaction spinning. Waste spandex fibers can be used as raw materials for spinning. By recycling waste spandex fibers, undergoing secondary melting, and adding various auxiliary materials, they can be re-spun, effectively reducing production costs. Before melting, waste spandex fibers need to be cut and shredded; therefore, a cutting and shredding device is proposed for this purpose.

[0003] Existing spandex filament cutting and shredding devices typically use a ventilation mechanism to extract and collect the spandex filament powder after cutting and shredding it. However, using a ventilation method can easily cause the spandex filament powder to be stirred up, making the collection of spandex filaments quite troublesome. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a spandex filament cutting and shredding device. The technical problem to be solved is that the spandex filament powder is easily stirred up when the exhaust mechanism is used, which makes it difficult to collect the spandex filament powder.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spandex filament cutting and shredding device, comprising a shredding box:

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art of spandex filament cutting and shredding without creative effort are within the scope of protection of the present utility model.

[0026] like Figure 1 , 2As shown in Figure 3, this utility model provides a spandex filament cutting and shredding device, including a shredding box 1: a rotating motor 13 is fixedly installed on one side of the shredding box 1, the output end of the rotating motor 13 passes through one side of the shredding box 1, a rotating roller 14 is fixedly installed on the output end of the rotating motor 13, one end of the rotating roller 14 passes through the other side of the shredding box 1, a plurality of cutting blades 12 are fixedly installed on the outer surface of the rotating roller 14, a flip cover 4 is movably installed on the upper end of the shredding box 1 via a hinge, a feed inlet 5 is connected to one side of the flip cover 4, two handles 6 are fixedly installed on one side of the flip cover 4, two hinge seats 7 are fixedly installed on one side of the flip cover 4 respectively, a rotating rod 8 is hinged inside the hinge seat 7, a limiting block 9 is fixedly installed on one side of the shredding box 1, the rotating rod 8 is adapted to the internal groove of the limiting block 9, a threaded cap 10 is threadedly connected to the outer surface of one end of the rotating rod 8, the threaded cap 10 is located at the lower end of the limiting block 9, and a controller 11 is fixedly installed on one side of the shredding box 1.

[0027] In order to reduce the use of the exhaust mechanism, avoid the problem of spandex powder being blown up, and make the collection effect better, the lower end of the crushing box 1 is equipped with a crushed material discharge device 2 that can collect spandex powder, which is used to collect the cut and crushed spandex powder and discharge it.

[0028] like Figure 4 As shown, the crushed material discharge device 2 includes a collection trough 21, which is located at the lower end of the inner wall of the crushing box 1. A rotating rod 23 is movably installed inside the collection trough 21, with both ends of the rotating rod 23 penetrating through both sides of the inner wall of the collection trough 21. An auger blade 24 is fixedly installed on the outer surface of the rotating rod 23. A slow-motion motor 22 is fixedly installed on one side of the crushing box 1, with its output end penetrating through one side of the crushing box 1. The output end of the slow-motion motor 22 is fixedly connected to one end of the rotating rod 23. A [missing information - likely a typo or missing word] is located on one side of the crushing box 1. The discharge port 25 is located on one side of the collection tank 21. Through the collection tank 21, the cut and crushed spandex powder can fall into the collection tank 21. Then, by starting the slow motor 22, the slow motor 22 drives the rotating rod 23 and the auger blade 24 to rotate, thereby moving the spandex powder in the collection tank 21. The moving spandex powder will be discharged from the discharge port 25. The use of the exhaust mechanism is reduced, the problem of spandex powder being blown up is avoided, and the collection effect is better.

[0029] Furthermore, in order to close the upper end of the collection trough 21 and prevent the spandex filaments from falling into the collection trough 21 during the cutting and crushing process, the crushing box 1 is equipped with a discharge sealing device 3 that can block the collection trough 21, which is used to close the upper end of the collection trough 21 when the spandex filaments are cut and crushed.

One end of the sliding rod 35 is fixedly connected to one side of the baffle 32. The baffle 32 is moved in the moving trough 31 by the electric push rod 33, thereby closing the upper end of the collection trough 21. This prevents the spandex filaments from falling into the collection trough 21 during the cutting and crushing process. After the spandex filaments are cut and crushed, the baffle 32 is pulled by the electric push rod 33 to make the spandex filament powder fall into the collection trough 21.

[0031] The working principle is as follows: When using this utility model, pull the handle 6 and rotate the flip cover 4 to press it onto the upper end of the utility model. Using the hinge seat 7, rotating rod 8, threaded cap 10 and limiting block 9, the flip cover 4 can be fixed to the upper end of the utility model.
