Description

Technical Field

[0001] The utility model relates to the technical field of polyamide fiber production, in particular to a waste recovery device for polyamide fiber materials. Background Art

[0002] Nylon, also known as nylon, is a polyamide fiber. It is a general term for thermoplastic resins containing repeated amide groups on the main chain of the molecule. It is the first synthetic fiber in the world and can be made into long or short fibers. Its outstanding advantage is that it has higher wear resistance than other fibers. Nylon waste materials refer to waste materials replaced after use. In order to improve the utilization efficiency of nylon, nylon waste materials need to be recycled.

[0003] For example, the Chinese patent application number: 202321632489.5 discloses a waste recycling device for polyamide fiber materials, including a box body, the top of which is fixedly connected to a feed port. The threaded rod is driven to rotate by a second motor, thereby driving the push plate on the outer edge of the threaded rod to move, thereby pushing the waste on the platform to the direction of the second crushing wheel below, and the second crushing wheel on the outer edge of the second rotating shaft is driven to rotate by the rotation of the third motor. The waste can be quickly crushed in the state where the two second crushing wheels turn in opposite directions to achieve secondary crushing. The setting of this structure can effectively crush and collect the waste multiple times to achieve the problem of waste utilization.

[0004] Although the above patent can crush the waste for multiple times, due to the lack of filtering structure to filter and screen the crushed waste in the above patent, in the waste after the initial crushing, the waste that meets the crushing requirements and does not meet the crushing requirements are crushed again, affecting the subsequent crushing effect and efficiency of the waste that does not meet the requirements, and it is impossible to repeatedly crush the waste that does not meet the requirements after crushing. In actual use, the waste that has been crushed for multiple times may still be mixed with a small amount of waste that does not meet the crushing requirements, thereby affecting the crushing effect of the waste. In view of this, we propose a waste recovery device for polyamide fiber materials. Utility Model Content
