Description

Technical Field

[0001] The present invention relates to the technical field of fiber production and reuse, and specifically to an intelligent production line for multi-process recycling of 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 now become the fiber variety with the widest use and the largest consumption. Because of its large market, the amount of polyester fiber scraps and waste generated each year is huge. At this time, in order to ensure the recyclability of resources, it is necessary to process and use the waste polyester fiber scraps.

[0003] The existing Chinese patent application with the publication number CN110791824A discloses a waste PET polyester recycling product production line, which includes a pelletizer 2, a conveyor 3, a silo 4, a feeder 5, a non-drying 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 non-drying 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. In this invention, the recycled polyester melt after melting, extrusion, and viscosity increase can be directly used to manufacture various PET polyester products, realizing the reuse of waste materials.

[0004] However, the polyester fiber production line has the following defects in specific use:

[0005] 1. When the existing polyester fiber production line reuses polyester fiber scraps in production and processing, it generally uses a fusing and extrusion method to make the polyester fibers into smaller polyester fiber particles to facilitate subsequent production and processing operations of various polyester fiber products. At the same time, in order to ensure the effect of fusing the polyester fiber scraps, it is generally necessary to grind and crush various polyester fiber scraps. However, in the traditional method of grinding and crushing polyester fiber scraps, the grinding and crushing effect on the polyester fiber scraps is poor, which easily leads to polyester fibers that do not meet the requirements being transmitted to the inside of the fusing and extrusion equipment, affecting the effect and efficiency of fusing and extruding the polyester fiber scraps, and easily causing blockage problems inside the fusing and extrusion equipment.

[0006] 2. When the existing polyester fiber production line processes polyester fiber scraps, multiple sets of driving components (such as motors, etc.) need to operate to complete operations such as crushing, grinding, and fusing and extrusion. At this time, the design of multiple sets of driving components results in a higher cost for the production line, and the vibration and noise generated during the operation of multiple sets of driving components are also greater, affecting the effect of recycling waste polyester fibers.

At the same time, when the first gear rotates, it will also drive the first transmission belt and the feeding auger connected by the side gear on its outer side to operate, automatically feed the polyester fiber waste (not meeting the standard after grinding and crushing) moved to the side of the feeding auger, and facilitate moving the non-standard polyester fiber waste back to the side of the grinding wheel for multiple grinding and crushing operations, ensuring that no blockage or other problems occur inside the fusing and extruding box during subsequent fusing and extrusion of the polyester fiber;

[0050] 3. In the multi-process intelligent production line for recycling polyester fibers, when grinding and crushing polyester fiber fertilizer, the rotation of a set of rotating shafts can, on the one hand, drive the grinding disc installed on the outside to rotate, and the centrifugal force of the rotation drives the polyester fiber to move outward (on the side of the grinding wheel), thereby improving the grinding effect of the polyester fiber. On the other hand, it can drive the outside through the triangular bracket, the connecting rod and the epicyclic gear (on the inside of the internal tooth ring) to rotate, so that the installed grinding wheel can rotate to automatically complete the rotary grinding operation of the polyester fiber, thereby improving the grinding and crushing effect of the polyester fiber.

[0051] 4. In the multi-process intelligent production line for recycled polyester fibers, after grinding and pulverizing, the ground polyester fibers are poured into the melt extrusion box through the diversion pipe, automatically completing the polyester fiber unloading operation. At the same time, as the rotating shaft grinds the next batch of polyester fibers, its rotational force also drives the sweeping blade to rotate, sweeping away the polyester fibers adhering to the inner wall of the diversion pipe, effectively preventing problems such as blockage in the diversion pipe.

[0075] In order to enable those skilled in the art to better understand the solution of this application, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0076] Please refer to Figures 1-13 , The circular recycling polyester fiber multi-process intelligent production line includes a base 10, a melting and extrusion box 20, a crushing box 30, a circular crushing mechanism 40 and a melting and extrusion assembly 50. The melting and extrusion box 20 is supported and fixed on the top of the base 10. A crushing box 30 is installed on the top of the melting and extrusion box 20. The crushing box 30 is connected to the crushing box 30 through a diversion pipeline 300. A circular crushing mechanism 40 is installed on the top of the crushing box 30. The circular crushing mechanism 40 grinds and crushes fiber waste and extends to the outside of the crushing box 30. The bottom of the circular crushing mechanism 40 is connected to a melting and extrusion assembly 50. The melting and extrusion assembly 50 extends into the melting and extrusion box 20 and is rotatably connected to the melting and extrusion box 20. Among them, the circular crushing mechanism 40 includes a gear drive assembly 70. The gear drive assembly 70 is installed at the center of the top of the crushing box 30, and a crushing and scraping assembly 80 is connected to the center of the bottom.

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

[0077] The above working principle: When reusing waste polyester fibers, the waste polyester fibers can be poured into the interior of the crushing box 30, and the gear drive assembly 70 is activated to operate, driving the crushing and scraping assembly 80 installed at the center of its bottom to operate, performing multiple continuous crushing and grinding operations on the poured waste polyester fibers to reduce the size of the waste polyester fibers. At the same time, when the crushing and scraping assembly 80 is operating, it will synchronously drive the circulating feeding assembly 90 connected to one side thereof to operate, feeding the waste polyester fibers that do not meet the grinding requirements, so that they can be moved back to the top of the crushing and scraping assembly 80 for multiple grinding and crushing operations, ensuring that when the waste polyester fibers are subsequently ground and crushed, the fusing and extrusion assembly 50 will not be affected by the larger polyester fibers in terms of its fusing and extrusion effect. And when the crushing and scraping assembly 80 is operating, it will also drive the fusing and extrusion assembly 50 to operate, automatically fusing and extruding the crushed polyester fiber particles, effectively reducing the cost and noise of producing and reusing polyester fibers.
