Description

Technical Field

[0001] This invention relates to the field of nylon filament recycling technology, and in particular to a green recycling device for nylon filament. Background Technology

[0002] Nylon 6 filament is a fiber made of polycaprolactam. It has good abrasion resistance and softness, as well as high strength and easy cleaning. Therefore, it is often used to produce textiles such as clothing, socks, carpets, and curtains, and has a large demand in daily life. However, due to its abrasion resistance and high strength, nylon 6 products are not easy to decompose naturally. Therefore, for the sake of environmental protection and resource conservation, nylon 6 products can be recycled through relevant physical or chemical methods.

[0003] Chemical recycling mainly involves first crushing and screening nylon 6 into pieces of a certain size, then feeding them into a dissolving device. Acidic or alkaline agents are added to dissolve the nylon 6 products. After the polymer chains of nylon 6 are decomposed into low molecular weight monomers or short-chain polymers, residual agents and impurities are removed through filtration and washing. Then, the relatively pure nylon 6 monomers or short-chain polymers undergo a polymerization reaction to reform high molecular weight polymers, which can then be used again as raw materials for fiber product production.

[0004] However, due to the inherent characteristics of dissolved nylon 6 products, large fragments remain after crushing. When using existing screening devices for screening, the screen plates are mostly fixed, causing these large fragments to block in front of or above the screen plates and unable to be discharged in time, affecting screening efficiency and thus reducing recycling efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a green recycling device for nylon filament, which solves the above-mentioned technical problems, facilitates the timely discharge of unqualified materials, and has high screening efficiency.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a green recycling device for nylon filament, comprising a recycling cylinder, wherein a feeding hopper is provided at the top left end of the recycling cylinder and a discharge port is provided at the right end, and a crushing component is provided in the feeding hopper for crushing nylon filament;

[0007] The screening assembly includes a rotating shaft disposed inside a recycling cylinder, a screening plate fixedly connected to the right end of the rotating shaft, a circular groove provided on the inner wall of the right end of the recycling cylinder, the screening plate being rotatably connected in the circular groove and having screen holes evenly provided, transverse grooves provided on both sides inside the recycling cylinder, and sliders symmetrically provided on the screening plate, the sliders being slidably connected to the transverse grooves;

[0008] Air separation unit is used to blow nylon filaments entering from the feed hopper toward the screen plate;

[0009] A temporary windbreak assembly is used to temporarily block the wind blowing towards the screening plate when impurities are discharged. The bottom of the recovery cylinder is provided with an arc-shaped impurity outlet, which is located between the temporary windbreak assembly and the screening plate.

[0010] A drive assembly is used to intermittently drive the rotating shaft to move left and right and to rotate back and forth. The recycling cylinder has a mounting cavity on one side, and the drive assembly is located in the mounting cavity.

[0011] By adopting the above technical solution, during the screening process, the crushing component in the feed hopper crushes the nylon filaments and automatically drops them into the recovery cylinder. The air separation component blows the fragments to the screening plate for screening. Qualified fragments pass through the screen holes and fall into the subsequent processing tank. The drive component rotates the shaft when the screening plate is in the circular chute, causing the screening plate to rotate 180°. This rotational screening avoids large fragments from sticking to the screen plate and clogging the screen holes, thus improving screening efficiency. Subsequently, the drive component moves the shaft, causing the screening plate to move to the left... As the screen moves, large pieces of material on the screening plate also move to the left. The temporary windbreak component blocks the screening air, causing the large pieces of material to automatically fall into the arc-shaped discharge port for secondary crushing. Then, the windbreak component is released, and the drive component moves the screen plate to the right and reverses 180° to reset the screen plate. When the screen plate moves to the right, it can also push the qualified material on the right side of the screen plate to the processing tank. While rotating the screen, it scrapes out the large pieces of material that need to be crushed again. The screen plate has a high utilization rate and can discharge large pieces of material in a timely manner, thus improving the screening efficiency.

[0012] A further configuration of the present invention is as follows: the driving assembly includes a guide cylinder rotatably disposed within the mounting cavity; the guide cylinder has an inner groove inside and an X-shaped groove on one side of its outer wall; a slide bar is provided on the outer wall of the rotating shaft, and the slide bar is slidably connected within the inner groove; a movable plate is fixedly disposed within the mounting cavity; a fixing ring is fixedly disposed at one end of the movable plate and an arc-shaped groove is fixedly disposed at the other end; the rotating shaft passes through the guide cylinder and is rotatably connected within the fixing ring; a cylindrical pin is slidably connected within the arc-shaped groove; a crank mechanism is disposed within the mounting cavity; the crank mechanism is fixedly connected to the cylindrical pin for driving the movable plate to move left and right; a second rotating rod is rotatably disposed within the mounting cavity; two sliding rods and two steering rods are evenly fixedly disposed at one end of the second rotating rod near the rotating shaft; the rotating rods and sliding rods are arranged alternately; the steering rods are slidably connected within the X-shaped groove for driving the guide cylinder to rotate and reset.

[0013] By adopting the above technical solution, a crank mechanism is set up to drive the cylindrical pin to rotate. During the process of the cylindrical pin rotating from the bottom to the left to the top, it drives the moving plate to move to the left and then to the right to reset, driving the rotating shaft and the screening plate to move left and right. Then, during the process of the cylindrical pin rotating from the top to the right to the bottom, the cylindrical pin only slides in the arc-shaped slide groove and does not drive the moving plate to move. The screening plate is located in the circular slide groove. During this process, the rotating rod rotates, driving the sliding rod and the steering rod to rotate. One steering rod is slidably connected in one side of the X-shaped slide groove, driving the guide cylinder to rotate 180°, realizing that the screening plate rotates 180° in the circular slide groove. Then, the cylindrical pin rotates from the bottom to the left to the top, and the moving plate moves back and forth left and right until the cylindrical pin rotates from the top to the right to the bottom again. At this time, the other steering rod moves to the other side of the X-shaped slide groove, driving the guide cylinder to reset in the opposite direction. Thus, the 180-degree rotation and automatic reset of the screening plate are completed sequentially, and two reciprocating movements of the screening plate constitute one cycle, realizing automatic impurity discharge and the rotation of the screening plate.

[0014] A further configuration of the present invention is as follows: the crank mechanism includes a rotating rod 1 rotatably connected in the mounting cavity and a screening motor; one end of the rotating rod 1 is fixedly connected to a pulley 1, and the other end is vertically fixed to a connecting rod; a cylindrical pin is vertically fixed to the end of the connecting rod away from the rotating rod 1; one end of the rotating rod 2 is fixedly provided with a pulley 2; the pulley 1 and the pulley 2 are connected by a belt; and the screening motor is used to drive the pulley 1 to rotate.

[0015] By adopting the above technical solution, the screening motor drives the rotating rod to rotate, which in turn drives the pulley, connecting rod, and cylindrical pin to rotate, thereby causing the pulley to rotate and driving the rotating rod to rotate. Only one screening motor is needed to realize the periodic rotation of the shaft and screening plate, which is convenient and has high processing efficiency.

[0016] A further feature of the present invention is that: arc-shaped baffles are fixed at the ends of the two sliding rods, and circular plates are fixed at the left and right ends of the guide cylinder. U-shaped through grooves are symmetrically provided on the left and right sides of the circular plates. When the arc-shaped baffles rotate to the position of the U-shaped through grooves, they are slidably connected with the U-shaped through grooves.

[0017] By adopting the above technical solution, when the cylindrical pin rotates from the bottom to the left to the top, the arc-shaped baffle is located in the upper and lower U-shaped through grooves and is slidably connected to the U-shaped through grooves, which can limit the guide cylinder and prevent the guide cylinder from rotating.

[0018] A further feature of the present invention is that the guide cylinder rotates at an angle of 180 degrees.

[0019] A further configuration of the present invention is as follows: the temporary windbreak assembly includes two elastic balls arranged symmetrically in front of the wind separator assembly; a sealing cylinder is fixedly mounted on the top of the outer side of the recovery cylinder; a piston is provided inside the sealing cylinder; an L-shaped push rod is fixedly mounted on the right end of the piston; the L-shaped push rod slides through the recovery cylinder and a short rod is vertically fixed at its bottom; the short rod is rotatably connected to the center of the screening plate; an air inlet valve and an air outlet valve are provided on the elastic balls; the sealing cylinder is connected to the air inlet valve; and a controller is also included, which is connected to the air outlet valve.

[0020] By adopting the above technical solution, when the L-shaped push rod moves to the left along the recovery cylinder with the rotating shaft, it pushes the piston to the left, inflating the elastic ball. The volume of the elastic ball increases, blocking the wind from the air separation component. At this time, the wind force blowing towards the screening plate is minimal, and large pieces of debris automatically fall into the impurity outlet. When the L-shaped push rod moves to the right along the recovery cylinder with the rotating shaft, it pushes the piston to the right. At this time, the controller controls the air outlet valve to open and release the air. The air separation component continues to feed material towards the screening plate to complete the screening, which facilitates the discharge of impurities and further improves the recovery efficiency of nylon filament.

[0021] A further feature of the present invention is that the air separation component includes two centrifugal fans arranged symmetrically in a vertical position, and the centrifugal fans are mounted on a partition plate.

[0022] By adopting the above technical solution, a centrifugal fan is set up to blow the crushed material to the direction of the screening plate for screening. Qualified material is blown away from the recovery cylinder, and unqualified material is on the left side of the screening plate.

[0023] A further feature of the present invention is that the crushing assembly includes two crushing rollers symmetrically arranged on the left and right sides and rotatably connected to the bottom of the feed hopper, and also includes a drive motor, the output end of which is fixedly connected to the crushing rollers for driving the crushing rollers to rotate.

[0024] By adopting the above technical solution, a drive motor is set up to drive two crushing rollers to rotate, thereby crushing nylon filaments.

[0025] A further feature of the present invention is that a partition is provided on one side of the mounting cavity to separate the mounting cavity from the recovery cylinder, and the rotating shaft passes through the partition.

[0026] By adopting the above technical solution, a partition is set to divide the installation cavity, which serves to protect the drive components.

[0027] The beneficial effects of this invention are:

[0028] 1. During the screening process, the crushing component breaks down the nylon filaments and automatically drops them into the recovery cylinder. The air separation component blows the fragments to the screening plate for screening. When the screening plate is located in the circular chute, the drive component drives the rotating shaft to rotate, causing the screening plate to rotate 180°. Screening occurs while rotating, which avoids large pieces of material sticking to the screen plate and clogging the screen holes, thereby improving screening efficiency. Subsequently, the drive component drives the rotating shaft to move, causing the screening plate to move to the left. Large pieces of material on the screening plate also move to the left. The temporary windbreak component blocks part of the screening air, causing large pieces of material to automatically fall into the arc-shaped discharge port for secondary crushing. Then, the drive component drives the screening plate to move to the right to reset, while simultaneously releasing the windbreak component. The screening plate reverses 180° to reset, allowing large pieces of material to be discharged in time. Screening occurs while removing impurities, further improving screening efficiency.

[0029] 2. This application sets up a crank mechanism to drive the cylindrical pin to rotate. During the process of the cylindrical pin rotating from the bottom to the left to the top, it drives the moving plate, rotating shaft, and screening plate to move to the left and then to the right to reset. Then, during the process of the cylindrical pin rotating from the top to the right to the bottom, the cylindrical pin only slides in the arc-shaped slide groove and does not drive the moving plate to move. The screening plate is located in the circular slide groove. During this process, the rotating rod rotates, driving the sliding rod and the steering rod to rotate. One steering rod is slidably connected in one side of the X-shaped slide groove, driving the guide cylinder to rotate 180°, so that the screening plate can rotate 180° in the circular slide groove. Then, the cylindrical pin rotates from the bottom to the left to the top, and the moving plate moves back and forth left and right until the cylindrical pin rotates from the top to the right to the bottom again. At this time, the other steering rod moves to the other side of the X-shaped slide groove, driving the guide cylinder to reset in the opposite direction. Thus, the 180-degree rotation and automatic reset of the screening plate and the two reciprocating movements of the screening plate constitute one cycle, realizing the reciprocating rotation and left and right movement of the screening plate, which facilitates the discharge of impurities.

[0030] 3. When the L-shaped pusher moves to the left along the recovery cylinder with the rotating shaft, it pushes the piston to the left, inflating the elastic ball. The volume of the elastic ball increases, blocking the wind from the air separation component. At this time, the wind force blowing towards the screening plate is very small, and large pieces of broken material automatically fall into the impurity outlet. When the L-shaped pusher moves to the right along the recovery cylinder with the rotating shaft, it pushes the piston to the right. At this time, the controller controls the air outlet valve to open and release air. The air separation component continues to feed material towards the screening plate to complete the screening, which facilitates the discharge of impurities and further improves the recovery efficiency of nylon filament.

[0041] The air separation component 6 is used to blow the nylon filaments entering from the feed hopper 2 toward the screen plate;

[0042] The temporary windbreak assembly 7 is used to temporarily block the wind blowing towards the screening plate 51 when impurities are discharged. The bottom of the recovery cylinder 1 is provided with an arc-shaped impurity discharge port 9, which is located between the temporary windbreak assembly 7 and the screening plate 51.

[0043] The drive assembly 8 is used to intermittently drive the rotating shaft 50 to move left and right and to rotate back and forth. The recycling cylinder 1 has an installation cavity on one side, and the drive assembly 8 is located in the installation cavity.

[0044] Specifically, such as Figure 2 , Figure 4 As shown, the drive assembly 8 includes a guide cylinder 800 rotatably disposed within the mounting cavity. The guide cylinder 800 has an inner groove 8001 inside and an X-shaped groove 8002 on one side of its outer wall. A sliding strip 801 is provided on the outer wall of the rotating shaft 50, and the sliding strip 801 is slidably connected within the inner groove 8001. A movable plate 802 is fixedly disposed within the mounting cavity. A fixing ring 803 is fixedly disposed at one end of the movable plate 802, and an arc-shaped groove 804 is fixedly disposed at the other end. The rotating shaft 50 passes through the guide cylinder 800 and is rotatably connected within the fixing ring 803. The mounting cavity is provided with… There is a crank mechanism 809, and a cylindrical pin 805 is provided at the end of the crank mechanism 809. The cylindrical pin 805 is slidably connected in the arc-shaped slide groove 804 to drive the moving plate 802 to move left and right. A rotating rod 806 is rotatably provided in the mounting cavity. Two sliding rods 807 and two steering rods 808 are evenly fixed at one end of the rotating rod 806 near the rotating shaft 50. The rotating rod and the sliding rod 807 are arranged alternately. The steering rod 808 is slidably connected in the X-shaped slide groove 8002 to drive the guide cylinder 800 to rotate and reset.

[0045] Specifically, such as Figure 2 , Figure 4 As shown, the crank mechanism 809 includes a rotating rod 8090 rotatably connected in the mounting cavity and a screening motor 8092. One end of the rotating rod 8090 is fixedly connected to a pulley 8091, and the other end is vertically fixed to a connecting rod 8093. A cylindrical pin 805 vertically fixes the end of the connecting rod 8093 away from the rotating rod 8090. One end of the rotating rod 806 is fixedly provided with a pulley 810. The pulley 8091 and the pulley 810 are connected by a belt. The screening motor 8092 is used to drive the pulley 8091 to rotate.

[0046] Specifically, such as Figure 4 As shown, the ends of the two sliding rods 807 are fixed with arc-shaped baffles 811, and the left and right ends of the guide cylinder 800 are fixed with circular plates 812. The circular plates 812 are symmetrically provided with U-shaped through grooves 813 on the left and right sides. When the arc-shaped baffles 811 rotate to the position of the U-shaped through grooves 813, they are slidably connected with the U-shaped through grooves 813.

[0047] Specifically, such as Figure 2 As shown, the temporary windbreak assembly 7 includes two elastic balls 70 arranged symmetrically in front of the wind separator assembly 6. A sealing cylinder 71 is fixed at the top of the outer side of the recovery cylinder 1. A piston is provided inside the sealing cylinder 71. An L-shaped push rod 72 is fixed at the right end of the piston. The L-shaped push rod 72 slides through the recovery cylinder 1 and a short rod 73 is fixed vertically at the bottom. The short rod 73 is rotatably connected to the center of the screening plate 51. An air inlet valve 74 and an air outlet valve 75 are provided on the elastic ball 70. The sealing cylinder 71 is connected to the air inlet valve 74. The assembly also includes a controller, which is connected to the air outlet valve 75.

[0048] Specifically, such as Figure 2 As shown, the air separation component 6 includes two centrifugal fans 60 arranged symmetrically at different heights, and the centrifugal fans 60 are mounted on the partition plate 61.

[0049] Specifically, such as Figure 2 , Figure 3 As shown, the crushing assembly 4 includes two crushing rollers 40 symmetrically arranged on the left and right sides and rotatably connected to the bottom of the feed hopper 2. The ends of the crushing rollers 40 are provided with pulleys, and the two pulleys are connected by a belt. It also includes a drive motor 41, the output end of which is fixedly connected to the crushing rollers 40 for driving the crushing rollers 40 to rotate.

[0050] Specifically, such as Figure 2 As shown, a partition 61 is provided on one side of the installation cavity to separate the installation cavity from the recovery cylinder 1, and the rotating shaft 50 passes through the partition 61.

[0051] Its working principle is as follows: First, the drive motor 41 and centrifugal fan 60 are turned on. The drive motor 41 drives the crushing roller 40 to rotate, thereby crushing the nylon filaments entering the feed hopper 2 into fragments. The centrifugal fan 60 blows the fragments to the direction of the screening plate 51 for screening. Qualified fragments fall into the subsequent processing tank through the screen holes 53 of the screening plate 51, while unqualified fragments remain at the left end of the screening plate 51. The screening motor 8092 is started to drive the rotating rod to rotate. The rotating rod drives the connecting rod 8093 and the cylindrical pin 805 to rotate. When the cylindrical pin 805 rotates from the bottom to the left to the top, it drives the moving plate 802 to move to the left and then to the right to reset, thereby driving the rotating shaft 50 and the screening plate 51 to move left and right. During this process, the arc-shaped baffle 811 slides up and down along the U-shaped groove, and the rotating shaft 50 does not rotate. When the cylindrical pin 805 is at the top, the screening plate 51 is located in the circular sliding groove. During the process of rotating the cylindrical pin 805 from the top to the right to the bottom, the cylindrical pin 805 only slides within the arc-shaped slide groove 804 and does not drive the moving plate 802 to move. During this process, the rotating rod 806 rotates, driving the steering rod 808 to rotate. One steering rod 808 is slidably connected to one side of the X-shaped slide groove 8002, driving the guide cylinder 800 and the screening plate 51 to rotate 180°. Then, the cylindrical pin 805 rotates from the bottom to the left to the top, and the moving plate 802 moves back and forth left and right until the cylindrical pin 805 rotates from the top to the right to the bottom again. At this time, the other steering rod 808 moves to the other side of the X-shaped slide groove 8002, driving the guide cylinder 800 to reverse and reset. Thus, the 180-degree rotation and automatic reset of the screening plate 51 and the two reciprocating movements of the screening plate 51 are completed as one cycle, realizing automatic impurity discharge and the rotation screening of the screening plate 51.

[0052] When the screening plate 51 moves to the left, the L-shaped push rod 72 moves to the left along the recovery cylinder 1 with the rotating shaft 50, pushing the piston to the left. At this time, air is injected into the elastic ball 70, and the volume of the elastic ball 70 increases, blocking the wind from the air separation component 6. At this time, the wind force blowing towards the screening plate 51 is extremely small, and large pieces of broken material automatically fall into the impurity outlet. When the L-shaped push rod 72 moves to the right along the recovery cylinder 1 with the rotating shaft 50, it pushes the piston to the right. At this time, the controller controls the air outlet valve 75 to open and release air. The air separation component 6 continues to feed material towards the screening plate 51 to complete the screening, which facilitates the discharge of impurities and further improves the recycling efficiency of nylon filament.
