Description

Technical Field

[0001] This invention belongs to the field of spandex filament recycling, specifically a method for shearing and dissolving regenerated spandex filaments. Device. Background Technology

[0002] Spandex (also known as elastic fiber or spandex) is a highly elastic synthetic fiber, usually made of polyurethane. Spandex is often used to make close-fitting clothing, such as sportswear, underwear and swimwear, to improve wearing comfort. In actual production, waste spandex needs to be recycled and regenerated. The collected waste spandex is cut, washed, dried, dissolved and shaped to regenerate the spandex. This requires a regenerated spandex cutting and dissolving device.

[0003] A patent application with publication number CN113308766A discloses an integrated production system and processing method for efficient regeneration of spandex filaments based on waste spandex filaments. The system includes a shearing device, a washing tank, a drying device, and a stirring device, which work together to recycle and regenerate waste spandex filaments.

[0004] The above-mentioned solution still has some problems in practical application. The clamping device is too cumbersome. In actual production, the cutting efficiency cannot be guaranteed when cutting waste spandex filaments. When dissolving waste spandex filaments, they are not mixed evenly, and the waste spandex filaments are prone to clumping, which affects the quality of subsequent recycled spandex filaments.

[0005] Therefore, the present invention provides a device for cutting and dissolving recycled spandex filaments. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A recycled spandex filament shearing and dissolving device of this invention includes a base, a trimming box fixedly installed above the base, a slot on the inner wall of the trimming box, a trimming device disposed above the interior of the trimming box, a feed inlet fixedly installed above the trimming box, a discharge outlet slidably installed below the trimming box, a dissolving tank fixedly installed on the base, the dissolving tank located on one side of the trimming box, a support plate fixedly installed above the dissolving tank, a motor fixedly installed above the support plate, a rotating shaft fixedly connected to the output end of the motor, the rotating shaft penetrating into the interior of the dissolving tank, a stirring rod fixedly installed on the rotating shaft, a roller fixedly installed above the rotating shaft, a slant plate sleeved on the rotating shaft, the slant plate contacting the roller, a spring fixedly installed below the slant plate, the other end of the spring fixedly connected to the top of the dissolving tank, a lifting rod fixedly installed at the lower end of the slant plate, the lifting rod penetrating into the interior of the dissolving tank, and a mixing block fixedly installed at the end of the lifting rod. A first feed pipe is fixedly installed on the upper part of one side of the dissolving tank, and a second feed pipe is fixedly installed on the upper part of the other side of the dissolving tank. A discharge pipe is fixedly installed at the lower end of the dissolving tank. The trimming device includes a fixing plate, which is fixedly installed on the inner wall of the trimming box. A first electric push rod is fixedly installed on one side of the fixing plate, and a blade is fixedly installed at the end of the first electric push rod. The trimming device also includes a second electric push rod, which is fixedly installed on the upper rear side of the trimming device. A T-shaped fixing rod is fixedly installed at the end of the second electric push rod. The T-shaped fixing rod passes through a slot on the trimming box. A first sliding block is fixedly installed at the lower end of the T-shaped fixing rod. A second sliding block is slidably installed on the first sliding block. The second sliding block is slidably installed inside the fixing block. Two second sliding blocks are symmetrically arranged. The fixing block 34 is fixedly installed on the inner wall of the trimming box. Clamping blocks are fixedly installed at the lower ends of the two second sliding blocks. Baffles are fixedly installed at the lower ends of the clamping blocks away from the blades.The collected waste spandex filaments enter the trimming box through the feed inlet. Initially, the second electric push rod is in the extended state. Activating the second electric push rod causes the T-shaped fixing rod to move away from the base. The T-shaped fixing rod then moves the first sliding block away from the base. The first sliding block causes the two second sliding blocks to move towards each other on the fixing block, thereby causing the two clamping blocks to move towards each other, ultimately clamping the waste spandex filaments. Activating the first electric push rod then moves the blade towards the baffle, cutting off the clamped waste spandex filaments. The waste spandex filaments are then removed through the discharge outlet, washed, dried, and enter the dissolving tank through the first feed pipe. Appropriate amounts of water and dissolving solution are added through the second feed pipe. Activating the motor causes the rotating shaft to rotate, which in turn drives the stirring rod. The spandex filament solution is stirred and mixed in the dissolving tank. A rotating shaft drives a second fixed block in a circular motion, which in turn drives a roller plate in a circular motion. The roller plate drives a roller to move in a circular motion on a swashplate. When the roller moves to a higher position on the swashplate, it presses the swashplate downwards, causing the swashplate to move downwards along with a lifting rod, compressing the spring. When the roller moves to a lower position on the swashplate, the spring extends, causing the swashplate to move upwards, which in turn drives the lifting rod upwards. During the circular motion of the roller on the swashplate, the lifting rod reciprocates within the dissolving tank, causing the mixing block to reciprocate. This, in conjunction with the stirring rod, performs compound stirring, ensuring the solution is thoroughly mixed within the dissolving tank and preventing clumping. After stirring, the solution is discharged through a discharge pipe for the next process.

[0008] Preferably, the size of the feed inlet is configured to match the trimming device, the discharge outlet is drawer-shaped, and a pull rod is provided on the discharge outlet; the combination of the feed inlet and the trimming device ensures that the waste spandex filaments are clamped by the clamping block during the falling process to prevent them from falling off, thus ensuring the trimming quality, and the pull rod allows for easy removal of the trimmed waste spandex filaments from the discharge outlet.

[0009] Preferably, the baffle is installed at a height that matches the fixed plate, and the size of the baffle is larger than the size of the blade. The first electric push rod is located at the center of the fixed plate. By installing the baffle at a height that matches the fixed plate and setting the size of the baffle, it is ensured that the blade can accurately cut the waste spandex filaments during movement.

[0010] Preferably, the second sliding block has a groove inside, and the first sliding block is slidably connected to the second sliding block through the groove inside the second sliding block. The fixed block has a groove inside, and the second sliding block is slidably connected to the fixed block through the groove inside the fixed block. By setting grooves in the second sliding block and the fixed block, the movement of the first sliding block and the second sliding block is more stable, and it can also play a limiting role.

[0011] Preferably, the top of the dissolving tank is provided with several through holes, through which the rotating shaft and the lifting rod pass; the rotating shaft and the lifting rod enter the interior of the dissolving tank through the through holes.

[0012] Preferably, the swashplate has a hole in its center, and the rotating shaft passes through the hole in the swashplate without contacting the swashplate. The rotating shaft passes through the central hole in the swashplate, so that the swashplate moves up and down evenly when the rollers are making circular motion, ensuring more stable operation. The fact that the rotating shaft does not contact the swashplate prevents friction from affecting work efficiency.

[0013] Preferably, the inlet, the first inlet pipe, the second inlet pipe and the outlet pipe are all equipped with solenoid valves; the inlet and outlet of materials are controlled by the solenoid valves.

[0014] Preferably, there are several stirring rods, all of which are arranged inside the dissolving tank and are distributed equidistantly around the circumference; the equidistant distribution of several stirring rods around the circumference can make the stirring process more comprehensive and stable.

[0015] Preferably, the lifting rods are symmetrically arranged below the swashplate, and the mixing block and the stirring rod are not in contact; the mixing block and the stirring rod are not in contact to prevent them from colliding and causing friction that would affect the mixing efficiency.

[0016] Preferably, a second fixing block is fixedly installed on the rotating shaft, and a roller plate is fixedly mounted on the lower end of the second fixing block. A roller is rotatably installed on the roller plate. The roller is connected to the second fixing block and the roller plate to make the roller run more stably.

[0017] The beneficial effects of this invention are as follows: 1. The regenerated spandex yarn shearing and dissolving device of the present invention reduces tedious shearing steps by using a trimming device and a blade in combination, thereby improving work efficiency while ensuring the completion of the work.

[0018] 2. The regenerated spandex yarn shearing and dissolving device of the present invention, by setting a lifting device in the dissolving tank, ensures that the solution in the dissolving tank is fully mixed, prevents clumping from affecting subsequent work, and improves product quality.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figure 1-5 As shown in the embodiment of the present invention, a regenerated spandex filament shearing and dissolving device includes a base 1, a trimming box 2 fixedly installed above the base 1, a slot on the inner wall of the trimming box 2, a trimming device 3 disposed above the interior of the trimming box 2, a feed inlet 4 fixedly installed above the trimming box 2, a discharge outlet 5 slidably installed below the trimming box 2, a dissolving tank 7 fixedly installed on the base 1, the dissolving tank 7 being located on one side of the trimming box 2, a support plate 15 fixedly installed above the dissolving tank 7, a motor 11 fixedly installed above the support plate 15, and a rotating shaft 12 fixedly connected to the output end of the motor 11, the rotating shaft 12 penetrating into the interior of the dissolving tank 7. A stirring rod 22 is fixedly installed on the rotating shaft 12. A roller 13 is fixedly installed above the rotating shaft 12. A slant plate 14 is sleeved on the rotating shaft 12 and contacts the roller 13. A spring 16 is fixedly installed below the slant plate 14. The other end of the spring 16 is fixedly connected to the top of the dissolving tank 7. A lifting rod 20 is fixedly installed at the lower end of the slant plate 14 and penetrates into the interior of the dissolving tank 7. A mixing block 21 is fixedly installed at the end of the lifting rod 20. A first feed pipe 8 is fixedly installed above one side of the outside of the dissolving tank 7. A second feed pipe 9 is fixedly installed above the other side of the outside of the dissolving tank 7. A discharge pipe 10 is fixedly installed at the lower end of the dissolving tank 7. The trimming device 3 includes a fixing plate 37, which is fixedly installed on the inner wall of the trimming box 2. A first electric push rod 38 is fixedly installed on one side of the fixing plate 37, and a blade 39 is fixedly installed at the end of the first electric push rod 38. The trimming device 3 also includes a second electric push rod 17, which is fixedly installed on the upper rear side of the trimming device 3. A T-shaped fixing rod 31 is fixedly installed at the end of the second electric push rod 17. The T-shaped fixing rod 31 passes through a slot on the trimming box 2. A first sliding block 32 is fixedly installed at the lower end of the T-shaped fixing rod 31. A second sliding block 33 is slidably installed on the first sliding block 32. The second sliding block 33 is slidably installed inside the fixing block 34. Two second sliding blocks 33 are symmetrically arranged. The fixing block 34 is fixedly installed on the inner wall of the trimming box 2. Clamping blocks 35 are fixedly installed at the lower ends of the two second sliding blocks 33. Baffles 36 are fixedly installed at the lower ends of the clamping blocks 35 away from the blade 39.

[0023] Specifically, the collected waste spandex filaments enter the trimming box 2 through the feed inlet 4. Initially, the second electric push rod 17 is in the extended state. Activating the second electric push rod 17 causes the T-shaped fixing rod 31 to move away from the base 1. The T-shaped fixing rod 31 then causes the first sliding block 32 to move away from the base 1. The first sliding block 32 causes two second sliding blocks 33 to move towards each other on the fixing block 34, thereby causing the two clamping blocks 35 to move towards each other, ultimately clamping the waste spandex filaments. Activating the first electric push rod 38 causes the blade 39 to move towards the baffle 36, cutting off the clamped waste spandex filaments. The waste spandex filaments are then removed through the discharge port 5, washed, dried, and enter the dissolving tank 7 through the first feed pipe 8. Appropriate amounts of water and dissolving solution are added through the second feed pipe 9. Activating the motor 11 causes the rotating shaft 12 to rotate, which in turn drives the stirring rod 22 to dissolve the waste spandex filaments. The spandex filament solution is stirred and mixed inside the dissolving tank 7. The rotating shaft 12 drives the second fixed block 18 to move in a circular motion. The second fixed block 18 drives the roller plate 19 to move in a circular motion. The roller plate 19 drives the roller 13 to move in a circular motion on the slant plate 14. When the roller 13 moves to a higher position on the slant plate 14, the roller 13 presses the slant plate 14 downward. The slant plate 14 moves downward with the lifting rod 20, and the spring 16 is compressed. When the roller 13 moves to a lower position on the slant plate 14, the spring 16 extends and drives the slant plate 14 to move upward. The slant plate 14 drives the lifting rod 20 to move upward. During the circular motion of the roller 13 on the slant plate 14, the lifting rod 20 moves back and forth in the dissolving tank 7, thereby causing the mixing block 21 to move back and forth. This, in conjunction with the stirring rod 22, performs compound stirring, ensuring that the solution is fully stirred in the dissolving tank 7 and preventing clumping. After stirring, the solution is discharged through the discharge pipe 10 for the next process.

[0024] The size of the feed inlet 4 is matched with that of the trimming device 3, the discharge outlet 5 is drawer-shaped, and a pull rod 6 is provided on the discharge outlet 5.

[0025] Specifically, the feed inlet 4 is designed in conjunction with the trimming device 3 so that the waste spandex filaments can be clamped by the clamping block 35 during the falling process to prevent them from falling off and to ensure the trimming quality. The pull rod 6 can easily remove the trimmed waste spandex filaments from the discharge port 5.

[0026] The baffle 36 is installed in conjunction with the fixed plate 37, and the size of the baffle 36 is larger than the size of the blade 39. The first electric push rod 38 is located at the center of the fixed plate 37.

[0027] Specifically, by matching the height of the baffle 36 with that of the fixed plate 37 and setting the size of the baffle 36, it is ensured that the blade 39 can accurately cut the waste spandex filaments during movement.

[0028] The second sliding block 33 has a sliding groove inside, and the first sliding block 32 is slidably connected to the second sliding block 33 through the sliding groove inside the second sliding block 33. The fixed block 34 has a sliding groove inside, and the second sliding block 33 is slidably connected to the fixed block 34 through the sliding groove inside the fixed block 34.

[0029] Specifically, by setting grooves in the second sliding block 33 and the fixed block 34, the movement of the first sliding block 32 and the second sliding block 33 becomes more stable, and it can also play a limiting role.

[0030] The top of the dissolving tank 7 is provided with several through holes, through which the rotating shaft 12 and the lifting rod 20 pass.

[0031] Specifically, the rotating shaft 12 and the lifting rod 20 enter the interior of the dissolving tank 7 through the through hole.

[0032] The swashplate 14 has a hole in the center, and the shaft 12 passes through the hole in the swashplate 14 without contacting the swashplate 14.

[0033] Specifically, the rotating shaft 12 passes through the central hole on the swashplate 14, so that the swashplate 14 moves up and down evenly when the roller 13 is in circular motion, ensuring more stable operation. The rotating shaft 12 and the swashplate 14 do not contact each other to prevent friction from affecting work efficiency.

[0034] Solenoid valves are installed inside the feed inlet 4, the first feed pipe 8, the second feed pipe 9, and the discharge pipe 10.

[0035] Specifically, the inflow and outflow of materials are controlled by solenoid valves.

[0036] Several stirring rods 22 are provided, and all of the stirring rods 22 are arranged inside the dissolving tank 7 and are distributed in a circumferentially equidistant manner.

[0037] Specifically, the fact that several stirring rods 22 are distributed equidistantly in a circle can make the stirring process more comprehensive and stable.

[0038] The lifting rod 20 is symmetrically arranged below the swashplate 14, and the mixing block 21 is not in contact with the stirring rod 22.

[0039] Specifically, the mixing block 21 and the stirring rod 22 do not come into contact to prevent them from colliding and causing friction that would affect the mixing efficiency.

[0040] A second fixing block 18 is fixedly installed on the rotating shaft 12, and a roller plate 19 is fixedly mounted on the lower end of the second fixing block 18. A roller 13 is rotatably installed on the roller plate 19.

[0041] Specifically, the roller 13 is connected to the roller plate 19 via the second fixing block 18 to make the roller 13 run more stably.

[0042] Working principle: The collected waste spandex filaments enter the trimming box 2 through the feed inlet 4. Initially, the second electric push rod 17 is in the extended state. Activating the second electric push rod 17 causes the T-shaped fixing rod 31 to move away from the base 1. The T-shaped fixing rod 31 then causes the first sliding block 32 to move away from the base 1. The first sliding block 32 causes two second sliding blocks 33 to move towards each other on the fixing block 34, thereby causing the two clamping blocks 35 to move towards each other, ultimately clamping the waste spandex filaments. Activating the first electric push rod 38 causes the blade 39 to move towards the baffle 36, cutting off the clamped waste spandex filaments. Pulling the pull rod 6 allows the waste spandex filaments to be removed through the discharge port 5 for cleaning and drying. After cleaning and drying, the filaments enter the dissolving tank 7 through the first feed pipe 8. Appropriate amounts of water and dissolving solution are added through the second feed pipe 9. Activating the motor 11 causes the rotating shaft 12 to rotate, which in turn drives the stirring rod 2. 2. The spandex filament solution is stirred and mixed in the dissolving tank 7. The rotating shaft 12 drives the second fixed block 18 to move in a circular motion. The second fixed block 18 drives the roller plate 19 to move in a circular motion. The roller plate 19 drives the roller 13 to move in a circular motion on the sloping plate 14. When the roller 13 moves to a higher position on the sloping plate 14, the roller 13 presses the sloping plate 14 downward. The sloping plate 14 carries the lifting rod 20 downward. The spring 16 is compressed. When the roller 13 moves to a lower position on the sloping plate 14, the spring 16 extends and drives the sloping plate 14 to move upward. The sloping plate 14 drives the lifting rod 20 to move upward. During the circular motion of the roller 13 on the sloping plate 14, the lifting rod 20 moves back and forth in the dissolving tank 7, thereby causing the mixing block 21 to move back and forth. This, in conjunction with the stirring rod 22, performs compound stirring, ensuring that the solution is fully stirred in the dissolving tank 7 and preventing clumping. After stirring, the solution is discharged through the discharge pipe 10 for the next process.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
