Description

Technical Field

[0001] The invention relates to the technical field of fiber production and recycling, and specifically to a multi-process intelligent production line for recycling polyester fibers. Background Art

[0002] Polyester fiber is a material with advantages such as high modulus, high strength, high elasticity, good shape retention and heat resistance. It has become the most widely used and consumed fiber variety. Because it has a large market, the amount of polyester fiber scraps and waste generated each year is huge. At this time, in order to ensure the reusability of resources, it is necessary to process and use the discarded polyester fiber waste.

[0003] The existing Chinese patent application with publication number CN110791824A discloses a production line for recycling waste PET polyester products, including a pelletizer 2, a conveyor 3, a silo 4, a feeder 5, a drying-free screw extruder 6, a primary filter 8, a liquid-phase viscosity-increasing reactor 9, a melt pump 14 and a secondary filter 13 arranged in sequence, the drying-free screw extruder 6 is connected to a vacuum pump A7, and the liquid-phase viscosity-increasing reactor 9 is connected to a vacuum pump B11; this invention can directly manufacture a variety of PET polyester products by melt-extruding the recycled polyester melt after viscosity-increasing filtration, thereby realizing the recycling of waste materials.

[0004] However, the polyester fiber production line has the following defects when used:

[0005] 1. When the existing polyester fiber production lines process and recycle polyester fiber waste, they generally use the method of melting and extruding to make polyester fiber into smaller polyester fiber particles, so as to facilitate the subsequent production and processing of various polyester fiber products. At the same time, in order to ensure the effect of melting the polyester fiber waste, it is generally necessary to grind and crush the various polyester fiber wastes. However, the traditional method has poor grinding and crushing effect on the polyester fiber waste, which can easily lead to the transmission of unqualified polyester fibers to the inside of the melting and extrusion equipment, affecting the effect and efficiency of melting and extruding the polyester fiber waste, and easily causing blockage problems inside the melting and extrusion equipment;

[0006] 2. When the existing polyester fiber production line processes polyester fiber waste, it needs multiple sets of driving parts (such as motors, etc.) to operate to complete operations such as crushing, grinding, melting and extrusion. At this time, the design of multiple sets of driving parts is relatively costly for the production line, and the vibration and noise generated by the multiple sets of driving parts during operation will also be greater, affecting the effect of reproducing and utilizing the waste polyester fiber.

[0076] See also Figure 1-Figure 13 The multi-process intelligent production line for recycling polyester fiber includes a base 10, a fusing extrusion box 20, a crushing box 30, a circulating crushing mechanism 40 and a fusing extrusion assembly 50. The top support of the base 10 is fixed with the fusing extrusion box 20. The crushing box 30 is installed on the top of the fusing extrusion box 20. The crushing box 30 is connected to the crushing box 30 through a guide pipe 300. The top of the crushing box 30 is installed with a circulating crushing mechanism 40. The circulating crushing mechanism 40 grinds and crushes the fiber waste and extends to the outside of the crushing box 30. The bottom of the circulating crushing mechanism 40 is connected with the fusing extrusion assembly 50. The fusing extrusion assembly 50 extends to the inside of the fusing extrusion box 20 and is rotatably connected to the fusing extrusion box 20.

The differential transmission assembly 100 is located on the other side of the gear drive assembly 70, and the bottom is connected to the fusing extrusion assembly 50.

[0077] The above working principle: when the discarded polyester fiber is recycled, the polyester fiber waste can be poured into the crushing box 30, and the gear drive assembly 70 is started to operate, driving the crushing and scraping assembly 80 installed at the bottom center to operate, and the poured polyester fiber waste is continuously crushed and ground for multiple times to reduce the size of the polyester fiber waste. At the same time, when the crushing and scraping assembly 80 is in operation, it will synchronously drive the circulating feeding assembly 90 connected to one side to operate, and feed the polyester fiber waste that has not completed the grinding requirements, so that it can be moved to the top of the crushing and scraping assembly 80 for multiple grinding and crushing operations, ensuring that when the polyester fiber waste is subsequently ground and crushed, the larger polyester fibers will not affect the melting and extrusion effect of the melting and extrusion assembly 50. In addition, when the crushing and scraping assembly 80 is in operation, it will also drive the melting and extrusion assembly 50 to operate, automatically fusing and extruding the crushed polyester fiber particles, effectively reducing the cost and noise of producing and recycling polyester fibers.
