[0002] From the beginning of the recognition of recycled fiber yarn to the increasing application of recycled raw materials in various types of textiles, the recycling of fibers has now developed on a large scale. In the past, the recycling of natural fibers was only associated with the production of low-quality fabrics, but the situation is very different today. With the continuous popularization and development of global resource recycling awareness, more and more waste fiber resources are recycled into recycled fibers. The use of recycled fibers has effectively improved the resource sustainability of textiles and effectively improved the efficiency of resource utilization. The enthusiasm of global consumers for recycled fibers has an important impact on the sustainable development of resources. Shoppers are paying more and more attention to the importance of this recycled fiber to global resource recycling. With the introduction of the GRS global recycling standard for international recycled fibers, recycled fibers have become one of the important ways to protect the environment and build a resource-saving society.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in combination with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Refer to the attached Figure 1 A crushing device for recycling nylon waste silk comprises a frame 1 and a cutting disc 10, a first conveying roller 5 and a second conveying roller 6 installed on the frame 1. A belt conveyor 2 is also installed on the frame 1. A fixed block 3 and a fixed plate 4 are arranged at intervals on the discharge side of the belt conveyor 2. Both ends of the fixed block 3 and the fixed plate 4 are fixed on the frame 1. The first conveying roller 5 and the second conveying roller 6 are respectively abutted against the top of the fixed block 3 and the fixed plate 4. The first conveying roller 5 and the second conveying roller 6 are driven by a roller motor 12 to rotate and convey the waste silk toward the cutting disc 10. The conveying speed of the first conveying roller 5 and the second conveying roller 6 is the same, and the rotating shafts at both ends of the first conveying roller 5 and the second conveying roller 6 are They are all installed on the pressure regulating mechanism 7, and the pressure regulating mechanism 7 is fixedly installed on the frame 1, wherein the pressure regulating mechanism 7 applies downward pressure to the first conveying roller 5 and the second conveying roller 6 to compress the waste silk, and the cutting disk 10 is arranged on the discharge side of the second conveying roller 6, and the cutting disk 10 cooperates with the fixed plate 4 for cutting the waste silk, and a longitudinal fixing plate 8 is arranged between the fixed block 3 and the fixed plate 4, and an opening is arranged in the middle of the longitudinal fixing plate 8, and the longitudinal fixing plate 8 is fixedly installed on the frame 1, and a screwing mechanism 9 is installed on the longitudinal fixing plate 8; wherein, the belt conveyor 2, the fixed block 3 and the top surface of the fixed plate 4 are flush, and the top surface of the fixed block 3 corresponds to the position of the square opening 911; so as to facilitate the horizontal transportation of the waste silk.

[0028] As mentioned above, the outer surfaces of the first conveying roller 5 and the second conveying roller 6 are wrapped with a rubber layer; the provision of the rubber layer can increase the friction between the roller and the waste silk, which is beneficial to the conveyance of the waste silk.

[0029] Among them, the distance from the intersection of the second conveying roller 6 and the fixed plate 4 to the end of the discharge side of the fixed plate 4 is 2-3 cm, so as to prevent the waste wire from being too far away from the cutting disk 10, and the twisted waste wire is easy to spread, which is not conducive to the crushing of the waste wire.

[0030] When in use, the waste silk strands are placed on the top of the belt conveyor 2, and the belt conveyor 2 conveys the waste silk toward the first conveying pressure roller 5. The first conveying pressure roller 5 presses the waste silk and conveys it to the twisting mechanism 9. The twisting mechanism 9 twists the waste silk into a strand. Some broken wires in the waste silk will also be wrapped in the stranded waste silk during the twisting process, which is beneficial to the traction of the waste silk (if the waste silk is disconnected, the subsequent waste silk cannot be pulled, and the disconnected waste silk can be twisted into a strand to achieve the connection of the broken wires and the traction of the waste silk). In addition, the rigidity of the twisted strand of waste silk will be enhanced, which is better for cutting than small strands or single wires (monofilament is softer and not convenient for cutting). The twisted strand of waste silk is conveyed to the cutting disk 10 via the second conveying pressure roller 6, and the cutting disk 10 rotates to cut and crush the stranded waste silk.

[0031] See attached Figure 1 As shown, further, the feed side of the fixed plate 4 is in an arc shape that is inclined downward; wherein, the feed side of the fixed plate 4 is inclined downward, which can play a guiding role, guiding the waste silk to the platform of the fixed plate 4, and this arrangement can effectively prevent the waste silk from being scratched and broken by the corners of the fixed plate 4.

[0032] See attached Figure 4-5 As shown, the screwing mechanism 9 includes a gear plate 91, a motor 96, a transmission gear 97 and a waste wire clamping mechanism. The gear plate 91 is rotatably connected to the side wall of the longitudinal fixed plate 8. A square opening 911 is provided in the middle of the gear plate 91. The square opening 911 corresponds to the opening position in the middle of the longitudinal fixed plate 8. The size of the square opening 911 is smaller than the size of the opening in the middle of the longitudinal fixed plate 8 to avoid interference of the middle opening of the fixed plate 8 with the waste wire traction during the waste wire traction process. A waste wire clamping mechanism is installed in the square opening 911, wherein the waste wire clamping mechanism applies pressure to the waste wire to clamp the waste wire. The motor 96 is fixedly installed on the longitudinal fixed plate 8. A transmission gear 97 is installed on the output shaft of the motor 96, and the transmission gear 97 is meshed with the gear plate 91. During the screwing process, the waste wire passes through the waste wire clamping mechanism in the square opening 911, and the motor 96 drives the gear plate 91 to rotate through the transmission gear 97. The gear plate 91 rotates to screw the waste wire into one strand.

[0033] See attached Figure 4-5As shown, the waste wire clamping mechanism includes a sliding plate 92, a pressure plate 93, a pressure spring 94 and a pressure adjusting bolt 95. Longitudinal slide rails 98 are arranged on the opposite side walls of the square opening 911. Two sets of sliding plates 92 are slidably connected to the longitudinal slide rails 98 on both sides. Two sets of pressure plates 93 are arranged between the two sets of sliding plates 92. The pressure plates 93 are all slidably connected to the longitudinal slide rails 98. Adjacent sliding plates 92 and pressure plates 93 are provided with pressure springs 94. The two ends of the pressure spring 94 are fixedly connected to the sliding plates 92 and the pressure plates 93 respectively. Two screw threads are connected to the side wall of the gear plate 91. The ends of the two groups of pressure adjusting bolts 95 are rotatably connected to the sliding plates 92 on both sides respectively; when in use, the waste wire passes through the two pressure plates 93, and the pressure spring 94 applies a clamping force to the waste wire through the pressure plates 93. When the clamping force needs to be adjusted, the pressure adjusting bolts 95 on both sides can be rotated. The rotation of the pressure adjusting bolts 95 will drive the sliding plate 92 to slide up and down along the slide rail 98, thereby adjusting the elastic force of the pressure spring 94; the two groups of sliding plates 92 can also be driven to rise and fall through the pressure adjusting bolts 95 on both sides, thereby realizing the adjustment of the clamping position of the waste wire.

[0034] See attached Figure 2-3 As shown, the pressure regulating mechanism 7 includes a frame 71, a slide rail 72, a lifting plate 73, a slider 74, a spring 75 and an adjusting bolt 76. The two side walls of the frame 71 are provided with slide rails 72. The slider 74 and the lifting plate 73 are slidably connected to the slide rails 72, and the lifting plate 73 is located above the slider 74. A spring 75 is fixedly connected between the lifting plate 73 and the slider 74. The top of the frame 71 is threadedly connected with an adjusting bolt 76. The lower end of the adjusting bolt 76 is rotatably connected to the lifting plate 73. The rotating shafts of the first conveying roller 5 and the second conveying roller 6 are both rotatably connected to the slider 74. By screwing the adjusting bolt 76, the lifting plate 73 can be driven to rise and fall, thereby adjusting the elastic force of the spring 75, thereby adjusting the pressure of the first conveying roller 5 and the second conveying roller 6. The setting of the pressure regulating mechanism 7 enables the first conveying roller 5 and the second conveying roller 6 to be lifted upward by a certain distance when conveying waste silk, and exerts pressure on the waste silk to make the waste silk pass through, thereby playing a role of avoidance.

[0035] The roller motor 12, which is used to drive the first conveying roller 5 and the second conveying roller 6 to rotate, is fixedly installed on the slider 74 of the pressure adjustment mechanism 7 on one side through the fixing frame 11; that is, when the first conveying roller 5 and the second conveying roller 6 move longitudinally, the roller motor 12 will also move longitudinally synchronously, ensuring the transmission of power.

[0036] See attached Figure 6As shown, the cutting disc 10 includes two groups of discs 101 arranged opposite to each other, and a connecting plate 102 is arranged along the circumference between the two groups of discs 101. The two ends of the connecting plate 102 are welded and fixedly connected to the discs 101 on both sides. The connecting plate 102 is detachably connected with a strip cutter 103, and the strip cutter 103 and the edge of the fixed plate 4 are transitionally matched, so as to achieve the cutting and crushing of the waste silk. A rotating shaft is arranged in the middle of the discs 101 on both sides, and the discs 101 on both sides are rotatably connected to the frame 1 through the rotating shaft. A driving motor (not shown in the drawings) for driving the discs 101 to rotate is installed on the outer wall of the frame 1, and the output shaft of the driving motor is connected to the rotating shaft of the disc 101. During cutting and crushing, the driving motor drives the disc 101 and the connecting plates 102 installed on the discs 101 on both sides and the strip cutter 103 to rotate. The strip cutter 103 rotates and cooperates with the fixed plate 4 to cut and crush the waste silk twisted into a strand delivered by the second conveying roller 6.

[0037] Furthermore, the strip cutter 103 is fixedly mounted on the connecting plate 102 by means of bolts and nuts. This arrangement facilitates the subsequent disassembly and replacement of the strip cutter 103 .
