Description

Technical Field

[0001] The invention relates to the technical field of non-woven fabric recycling, and in particular to a non-woven fabric waste recycling device and a processing method. Background Art

[0002] Non-woven fabrics are made of polyester fiber and polyester fiber and are made through a needle-punching process. They can be made into different thicknesses, feels, hardness, etc. They are moisture-proof, lightweight, flame-retardant, non-toxic and odorless, inexpensive, and recyclable. They are widely used in sound insulation, electric heaters, masks, and clothing industries. In order to improve the recycling rate of non-woven fabrics, non-woven fabrics that can be recycled are generally screened out, pre-treated, and then put into production. Commonly used pretreatment methods include cleaning, disinfection, and crushing.

[0003] However, when the non-woven fabric is shredded, in order to ensure that the non-woven fabric can be completely shredded and not incompletely shredded due to large-area folding, a whole piece of non-woven fabric waste is generally cut into thin strips by manual cutting before shredding. However, this manual cutting method is relatively traditional. On the one hand, it requires more manpower. On the other hand, the cutting and shredding cannot be carried out in parallel. The two processes are not consistent enough, which greatly reduces the shredding efficiency.

[0015] The present invention also provides a method for processing recycled nonwoven waste, comprising the following steps:

[0016] S1. Fix the non-woven waste: first start the motor five in the forward direction, and its output shaft drives the one-way screw three to rotate, so that the mold frame two moves toward the mold frame one, until the distance between the two is adjusted to a shorter distance, first take out the whole piece of non-woven fabric, put one side of it on the multiple fixed strips corresponding to the mold frame one, and then put the other side on the multiple fixed strips corresponding to the mold frame two, start the two motors one in the forward direction, and the output shafts of the two motors one drive the corresponding one-way screw one to rotate, so that the pressure strip and the movable strip are lowered, and finally the non-woven fabric is clamped, and then the motor five is started in the reverse direction to straighten the non-woven fabric;

[0017] S2, cutting the non-woven fabric waste into thin strips: first lift up the movable lever to bring it out of the corresponding limit hole, then horizontally move the inverted U-shaped frame, and according to the actual length of the non-woven fabric waste, move the movable lever to the specified position and then release it, so that it can be directly inserted into the specified limit hole to form a movable limit for the slide, and then start the motor three, the saw blade starts to rotate, and then start the output shaft of the cylinder to extend, so that the saw blade contacts the straightened non-woven fabric and cuts the part, after cutting, start the motor two in the forward direction, its output shaft drives the one-way screw two to rotate, the saw blade starts to move horizontally, and finally the original whole piece of non-woven fabric is transformed into thin strips;

[0018] S3. Crush the thin strips of non-woven fabric: first turn on motor four, and the two crushing rollers rotate relative to each other. Then, turn off motor three, stop the saw blade, and then start the output shaft of the cylinder to retract, bring the saw blade back to its original height, and then reversely start motor two to bring the saw blade back to its original position. Subsequently, reversely start the two motors one to loosen the non-woven fabric. The loosened non-woven fabric loses its limit and falls directly from the fixed bar under the action of gravity and falls into the crushing box. Under the crushing of the crushing roller, the thin strips of non-woven fabric are directly crushed and fall directly into the corresponding receiving vehicle through the guide channel steel.

[0038] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0039] First Embodiment:

[0040] Please refer to Figure 1-Figure 10 , in the first embodiment of the present invention, the non-woven waste recycling equipment includes: a workbench 1 and a gantry 2 fixed on the top of the workbench 1. Above the workbench 1, there are a C-shaped frame one 3 and a C-shaped frame two 4. Among them, the C-shaped frame one 3 is fixedly connected to the inner wall of one side of the gantry 2, and on the sides of the C-shaped frame one 3 and the C-shaped frame two 4 that are close to each other, there are fixed connection plates 5. On the sides of the two connection plates 5 that are close to each other, there are fixed a plurality of fixed bars 6. Inside the C-shaped frame one 3 and the C-shaped frame two 4, there are rotatably installed one-way screws one 7. On the two one-way screws one 7, there are threadedly installed pressing bars 8. And in order to ensure that the pressing bars 8 can perform stable linear lifting, there are fixed vertical rods inside the C-shaped frame one 3 and the C-shaped frame two 4. The two vertical rods penetrate through the corresponding pressing bars 8 and are slidably connected to the corresponding pressing bars 8. The sides of the two pressing bars 8 that are close to each other respectively extend outside the two connection plates 5, and on the two connection plates 5, there are opened sliding grooves. The top end surfaces of the fixed bars 6 are on the same horizontal plane as the bottom inner walls of the sliding grooves. And the two pressing bars 8 pass through the corresponding sliding grooves and are in contact with the inner walls of the sliding grooves. At the bottoms of the two pressing bars 8, there are fixed a plurality of movable bars 9. The plurality of movable bars 9 are respectively adapted to the plurality of fixed bars 6. Through the descent of the movable bars 9, the fixed bars 6 can finally be clamped. Inside the gantry 2, there is rotatably installed a one-way screw two 10. On it, there is threadedly installed a sliding plate 11. And at the bottom of the sliding plate 11, there is fixed a frame 12. Inside the frame 12, there is fixed a cylinder 13. Its output shaft is movably connected to the bottom of the frame 12. And on the output shaft of the cylinder 13, there is fixed a concave seat one 14. And at the bottom of the frame 12, there are slidably installed two limiting rods. The bottom ends of the two limiting rods are fixedly connected to the concave seat one 14 to prevent the output shaft of the cylinder 13 from rotating. And inside the concave seat one 14, there is rotatably installed a rotating shaft 15. On it, there is fixedly sleeved a plurality of saw blades 16. The plurality of saw blades 16 are staggered with the plurality of fixed bars 6 and the plurality of movable bars 9. In this way, when the saw blades 16 descend, they can pass through the spaces between two adjacent fixed bars 6 and between two adjacent movable bars 9, so as to realize the cutting of the non-woven waste. On the workbench 1, there is opened a blanking port 18. And below the workbench 1, there is a crushing mechanism for crushing the non-woven waste. And the provided blanking port 18 is located above the crushing mechanism, so that the cut non-woven fabric can be directly introduced into the crushing mechanism for crushing. And on one side of the gantry 2, there is a pushing mechanism to drive the C-shaped frame two 4 to perform linear horizontal movement, so as to be able to adjust the distance between the C-shaped frame two 4 and the C-shaped frame one 3, and to be able to straighten the fixed non-woven fabric, which is convenient for sawing.

[0041] In the above - mentioned manner, a first motor is fixed to the top of each of the U - shaped frame one 3 and the U - shaped frame two 4. The output shafts of the two first motors are respectively fixedly connected to the tops of the two one - way screws one 7. And a second motor is fixed to the outer wall of one side of the gantry 2, and its output shaft is fixedly connected to one end of the one - way screw two 10. A third motor is fixed to the outer wall of one side of the concave - shaped seat one 14, and its output shaft is fixedly connected to one end of the rotating shaft 15, so as to provide power rotation drive for each shaft - type part that needs to rotate.

[0042] In the above - mentioned crushing mechanism, there is a crushing box 17 with an open top. The crushing box 17 is fixed to the bottom of the workbench 1, and its top opening corresponds to the material - falling opening 18 up and down. Two connecting rods 19 are rotatably installed in the crushing box 17. The same - direction ends of the two connecting rods 19 extend outside the crushing box 17, and crushing rollers 20 located in the crushing box 17 are fixedly sleeved on the two connecting rods 19. The two crushing rollers 20 are meshed with each other, so as to achieve a good crushing effect. A fourth motor is fixed to the outer wall of one side of the crushing box 17, and its output shaft is fixedly connected to one end of one of the connecting rods 19. In order to drive the two connecting rods 19 to rotate simultaneously, gears are fixedly sleeved on the two connecting rods 19, and the two gears are meshed with each other. The bottom of the crushing box 17 is provided with a discharge port for discharging the crushed non - woven fabric.

[0043] In the above - mentioned pushing mechanism, there is a U - shaped frame three 21. The U - shaped frame three 21 is fixed to the outer wall of one side of the gantry 2. A one - way screw three 22 is rotatably installed therein. A fifth motor is fixed to the outer wall of one side of the U - shaped frame three 21, and its output shaft is fixedly connected to one end of the one - way screw three 22. A sliding plate 23 is threadedly installed on the one - way screw three 22. In order to ensure the stable linear horizontal movement of the sliding plate 23, a cross - bar is fixed in the U - shaped frame three 21. The cross - bar penetrates through the sliding plate 23 and is slidably connected to it. And a push rod 24 is fixed to the side of the sliding plate 23 close to the gantry 2. One end of it extends into the gantry 2 and is fixedly connected to the U - shaped frame two 4. And the push rod 24 is slidably connected to the gantry 2. In this way, when the one - way screw three 22 rotates, it can push the U - shaped frame two 4 to move horizontally.

[0044] The gantry 2 has a plurality of limit holes 29 formed on the top of the gantry 2, and a square rod 26 is fixed on the top of the gantry 2. A slider 27 is slidably mounted on the square rod 26. An inverted U-shaped frame 28 is fixed to the bottom of the slider 27. A movable lever 30 is slidably mounted in the inverted U-shaped frame 28. The bottom end of the movable lever 30 extends into the corresponding limit hole 29. By plugging the movable lever 30 into the limit hole 29, a horizontal upper limit can be provided for the slider 11, providing a limit function for the final position during movement, thereby preventing the saw blade 16 from colliding with the gantry 2.

[0045] In the present method, when a material receiving trolley is full, in order not to interrupt the material receiving process, a concave seat 2 31 can be provided under the crushing box 17, in which a central shaft 32 is rotatably installed, and a rocking seat 33 is fixedly sleeved on the central shaft 32, and a guide channel steel 34 is fixed on the top of the rocking seat 33, and the guide channel steel 34 is located below the discharge port of the crushing box 17, and a motor 6 is fixed on the outer wall of one side of the concave seat 2 31, and its output shaft is fixedly connected to one end of the central shaft 32. Before processing the non-woven waste, the material receiving trolleys are placed on the left and right sides of the concave seat 2 31, and in the initial state, the guide channel steel 34 is tilted to one side and is located above one of the material receiving trolleys. The tilt direction of the guide channel steel 34 can be adjusted by the forward and reverse rotation of the central shaft 32, thereby changing the material receiving position, so that the two material receiving trolleys can be used alternately.

[0046] In this embodiment:

[0047] When the non-woven waste is crushed, the motor five is first started in the positive direction, and its output shaft drives the one-way screw three 22 to rotate, so that the sliding plate 23 moves horizontally. At this time, through the push of the top rod 24, the type frame two 4 moves in the direction of the type frame one 3 until the distance between the two is short. Then, the whole piece of non-woven fabric can be taken out first, and then one side of it is placed on the multiple fixed strips 6 corresponding to the type frame one 3, and then the other side is placed on the multiple fixed strips 6 corresponding to the type frame two 4. Then, the two motors one are started in the positive direction, and the output shafts of the two motors one drive the corresponding one-way screw one 7 to rotate, so that the pressure strip 8 and the movable strip 9 are lowered, and finally the non-woven fabric is clamped, and then the motor five is started in the reverse direction, and the type frame two 4 moves away from the type frame one 3 until the non-woven fabric is straightened and the motor five is turned off;

[0048] Then, start the motor 3 first, and its output shaft drives the rotating shaft 15 and the saw blade 16 to rotate, and then start the output shaft of the cylinder 13 to extend, and the saw blade 16 will contact the straightened non-woven fabric and cut the part. After cutting, start the motor 2 in the positive direction, and its output shaft drives the one-way screw 2 10 to rotate, so that the slide plate 11 and the frame 12 can be driven to move horizontally, so that the saw blade 16 can be driven to move horizontally, and the non-woven fabric is gradually cut, until the saw blade 16 moves from one side of the non-woven fabric to the other side, and then all the cutting work is completed, and the original whole piece of non-woven fabric is transformed into thin strips;

[0049] Then, the motor 4 is turned on first, and its output shaft drives the corresponding connecting rod 19 to rotate, and then the other connecting rod 19 can be driven to rotate through two meshing gears, so that the two crushing rollers 20 rotate with each other, and then the motor 3 is turned off, the saw blade 16 stops rotating, and then the output shaft of the cylinder 13 is retracted to bring the saw blade 16 back to its original height, and then the motor 2 is started in reverse to bring the saw blade 16 back to its original position, and then the two motors 1 are started in reverse, the movable bar 9 starts to rise, and the non-woven fabric is loosened. After the non-woven fabric is loosened, it loses its limit and will fall directly from the fixed bar 6 under the action of gravity, and fall into the crushing box 17 through the drop opening 18. After falling in, the thin strips of non-woven fabric will be directly crushed by the crushing roller 20, and fall directly into the corresponding receiving vehicle through the guide channel steel 34;

[0050] After that, the next piece of non-woven waste to be crushed can be clamped on the fixing strip 6 in the same manner as above, and then it can be sawed and then crushed;

[0051] In the subsequent use, in order to prevent the saw blade 16 from colliding with the U-shaped frame 24 during the horizontal cutting process, the movable lever 30 can be lifted up before sawing to bring it out of the corresponding limiting hole 29, and then the inverted U-shaped frame 28 can be horizontally moved. According to the actual length of the non-woven waste, the movable lever 30 is moved to the specified position, and then it is loosened and directly inserted into the specified limiting hole 29 under the action of gravity, thereby forming a movement restriction on the slide plate 11. In this way, when the slide plate 11 contacts the movable lever 30 in the adjusted position, the saw blade 16 will not move anymore, thereby preventing it from colliding with the U-shaped frame 24;

[0052] At the same time, in subsequent use, when one of the receiving carts is full of crushed non-woven fabrics, the motor six can be started in reverse, and its output shaft can rotate with the central shaft 32, and then can rotate with the guide channel steel 34 around the axis of the central shaft 32, and finally tilt it to the other side, so that the crushed non-woven fabric can be guided to another empty receiving cart, and then the receiving cart full of non-woven fabrics can be pushed away and put back after dumping.

[0053] Compared with the related art, the non-woven waste recycling equipment provided by the present invention has the following beneficial effects:

[0054] In this embodiment, by setting a plurality of saw blades 16 staggered with a plurality of fixed bars 6 and movable bars 9, the whole piece of non-woven fabric waste can be sawn into a plurality of thin strips before the crushing process, and then the thin strips of non-woven fabric waste are crushed by the crushing roller 20, so that the size of the crushed non-woven fabric scraps can be uniform, and the thin strips of non-woven fabric will basically not fold over a large area, thereby ensuring the thoroughness of the crushing, without the need for secondary crushing, and the non-woven fabric can naturally fall into the crushing mechanism below for crushing after the strips are cut, and the two processes can be carried out in line, thereby improving the crushing efficiency;

[0055] In addition, by setting the pushing mechanism, the distance between the mold frame 2 4 and the mold frame 1 3 can be adjusted according to the actual size of the non-woven waste, so that the cutting work of non-woven waste of different sizes can be satisfied, and the applicability is strong.

[0056] Second embodiment:

[0057] Based on the non-woven waste recycling equipment provided in the first embodiment of the present application, the second embodiment of the present application proposes another non-woven waste recycling equipment. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0062] In this embodiment:

[0063] Before cutting the non-woven waste, in order to improve the cleanliness of the non-woven fabric, a certain amount of non-woven fabric can be taken out first, and then put into the cleaning basket 1 41 and the cleaning basket 2 44, and then add clean water into the two ultrasonic cleaning machines 36, and then start the ultrasonic cleaning machine 36 corresponding to the cleaning basket 2 44, and then the non-woven fabric can be ultrasonically cleaned. After the cleaning is completed, the motor 7 is started in the forward direction, and its output shaft drives the bidirectional screw 38 to rotate, and the lifting plate 1 39 and the lifting plate 2 42 begin to move towards each other. At this time, the cleaning basket 1 41 will gradually descend and enter the corresponding ultrasonic cleaning machine 36, and the cleaning basket 2 44 will gradually move upward out of the corresponding ultrasonic cleaning machine 36 until the cleaning is completed. After the basket 1 41 completely enters the ultrasonic cleaning machine 36 and the cleaning basket 2 44 is completely removed from the ultrasonic cleaning machine 36, the corresponding ultrasonic cleaning machine 36 is started to clean the non-woven fabric in the cleaning basket 1 41. On the other hand, the motor 7 is first turned off, and then the air valve on the air duct 2 47 corresponding to the cleaning basket 2 44 is opened, and then the hot air blower 45 is started, and the hot air will pass through the air duct 2 47 into the corresponding air duct 3 48 and air duct 4 49, and finally be ejected through the corresponding horn nozzle 50, and the hot air will pass through the holes on the cleaning basket 2 44 and blow directly to the cleaned non-woven fabric, so that the non-woven fabric can be drained while being assisted by the hot air, thereby achieving a faster draining work;

[0064] When the water on the non-woven fabric is almost drained, it can be taken out, cut and crushed. At the same time, the next piece of non-woven waste to be processed is put into the cleaning basket 2 44 again. After the previous non-woven waste is cleaned, the motor 7 is started in reverse, the cleaning basket 2 44 starts to descend, and the cleaning basket 1 41 starts to rise until the cleaning basket 2 44 descends into the corresponding ultrasonic cleaning machine 36 and the cleaning basket 1 41 is moved out of the corresponding ultrasonic cleaning machine 36. The air valve on the corresponding air duct 2 47 can be opened to drain the cleaned non-woven fabric more quickly. After the water is drained to a certain extent, it can be cut and crushed. In the future, this reciprocating process can be used by alternating the cleaning basket 1 41 and the cleaning basket 2 44 up and down.

[0065] The present invention also provides a method for processing recycled nonwoven waste, comprising the following steps:

[0066] S1.

[0067] S2, cutting the non-woven fabric waste into thin strips: first lift up the movable lever 30 and bring it out of the corresponding limiting hole 29, then horizontally move the inverted U-shaped frame 28, and according to the actual length of the non-woven fabric waste, move the movable lever 30 to the specified position and then release it, so that it can be directly inserted into the specified limiting hole 29, forming a movable limit for the slide plate 11, and then start the motor three, the saw blade 16 starts to rotate, and then start the output shaft of the cylinder 13 to extend, so that the saw blade 16 contacts the straightened non-woven fabric and cuts the part, after cutting, start the motor two in the forward direction, its output shaft drives the one-way screw two 10 to rotate, the saw blade 16 starts to move horizontally, and finally the original whole piece of non-woven fabric is transformed into thin strips;

[0068] S3. Crush the thin strips of non-woven fabric: first turn on motor 4, and the two crushing rollers 20 rotate relative to each other. Then, turn off motor 3, stop the saw blade 16, and then start the output shaft of cylinder 13 to retract, bring the saw blade 16 back to its original height, and then reversely start motor 2 to bring the saw blade 16 back to its original position. Subsequently, reversely start the two motors 1 to loosen the non-woven fabric.
