Description

Technical Field

[0001] This invention belongs to the field of raincoat material production technology, specifically a production device and process for biodegradable nonwoven raincoat material. Background Technology

[0002] Non-woven fabric, also known as needle-punched non-woven fabric, is made of polyester fiber and is produced through a needle-punching process. It can be made in different thicknesses, feels, and hardnesses. Non-woven fabric has the characteristics of being moisture-proof, breathable, flexible, lightweight, inexpensive, and recyclable. Non-woven fabric is widely used in the production of raincoats. During the production process, non-woven fabric needs to be cut into certain sizes to produce raincoats.

[0003] A patent application with publication number CN108396540A discloses a nonwoven fabric cutting and automatic adjustment device and its control method, including S1, inputting control parameters; S2, judging the feeding situation; S3, adjusting the cutting width; S4, judging by the tension threshold; S6-S10 are corresponding to different tension adjustment processes to avoid the problems of machine jamming and width error during nonwoven fabric transmission, ensuring the quality of nonwoven fabric cutting edge and realizing the automation of production.

[0004] When using nonwoven fabric to produce raincoats, the above-mentioned method uses fixed cutting dimensions when cutting nonwoven fabric to produce raincoats. This results in the inability to cut nonwoven fabric of various sizes into a single cutting device, which reduces the efficiency of nonwoven fabric cutting and increases the equipment and cost required for cutting nonwoven fabric.

[0005] Therefore, the present invention provides a production apparatus and process for biodegradable nonwoven raincoat material. Summary of the Invention

The cutting device includes a fixed cylinder fixed to one side of the dividing groove, a sliding plate slidably connected inside the fixed cylinder, a sliding cylinder slidably connected to the sliding plate, and a cutting shear fixed between the two sliding cylinders.

[0009] Preferably, the cutting device further includes a sliding column fixed inside the sliding cylinder, a locking block slidably connected inside the sliding cylinder, the locking block being slidably connected to the sliding column, a second spring being sleeved on the sliding column, one end of the second spring being fixedly connected to the sliding cylinder, the other end of the second spring being fixedly connected to the locking block, a locking groove being formed on one side of the fixed cylinder, the locking block engaging with the locking groove, a fixed column being fixedly connected to one side of the sliding plate, the sliding cylinder being slidably connected to the fixed column, a first spring being sleeved on the fixed column, one end of the first spring being fixedly connected to the sliding plate, and the other end of the first spring being fixedly connected to the sliding cylinder.

[0010] Preferably, the cutting device further includes a toothed plate fixed to the bottom of the sliding plate, the toothed plate being slidably connected to the fixed cylinder, and a first gear being fixed to both sides of the rotating rod, with each of the two first gears meshing with the toothed plate.

[0011] Preferably, the dividing frame is fixedly connected to a cutting block on one side of the cutting scissors, and a cutting opening is provided on one side of the cutting block.

[0012] Preferably, one end of the rotating rod passes through the dividing frame and is fitted with a rotating cylinder. Both sides of the rotating cylinder are fixedly connected with insert blocks. The dividing frame has two insertion holes, and the two insert blocks are slidably connected to the insertion holes respectively.

[0013] Preferably, the rotating rod is fixed to two sliders on one side inside the rotating cylinder, and two sliding grooves are formed inside the rotating cylinder, with the two sliders slidably connected to the sliding grooves.

[0014] Preferably, both sides of the take-up roller are fixedly connected with toothed racks, both sides of the rotating roller are rotatably connected with toothed conveyor belts, a second motor is fixedly connected inside the rotating roller between the two toothed conveyor belts, and a second gear is fixedly connected to the output end of the second motor.

[0015] Preferably, the dividing frame is provided with a transfer roller on the lower side of the take-up roller, and the dividing frame is provided with a movable plate on one side of the transfer roller, the movable plate being slidably connected to the dividing frame via a slide rail.

[0016] A production process for a biodegradable nonwoven raincoat material, the process employing the aforementioned production apparatus for biodegradable nonwoven raincoat material, includes the following steps:

[0017] Step 1: Select suitable fiber materials, pre-treat the raw fiber materials, and break the fibers by melting or shearing and then combining them.

[0018] Step 2: The broken fibers are laid out into a web using methods such as wet, dry, or hot air methods to evenly distribute the fibers on the web laying machine.

[0019] Step 3: The fibers after the web is laid are further heated and heat-set to make the fibers bond together. During the production process, dyes, coatings or other treatments may be added to the non-woven fabric to meet specific needs. After processing, the finished non-woven fabric is wound or cut.

[0020] Step 4: Place the nonwoven fabric on the drive roller and the take-up roller. The nonwoven fabric is transferred to the take-up roller by the combined action of multiple drive rollers. During the transfer process of multiple drive rollers, the nonwoven fabric is cut and divided. When dividing the nonwoven fabric, start the first motor to rotate the threaded rod. Start the telescopic rod to push the dividing knife against the thread on the threaded rod. When the threaded rod rotates, the dividing knife engages with the thread on the threaded rod. The dividing knife can then move along the length of the threaded rod. When the dividing knife reaches the required dividing size, the telescopic rod pushes the next dividing knife. The distance and number of dividing knives can be controlled by controlling the extension and retraction of the telescopic rod, so that the dividing knife divides the nonwoven fabric into the required size. The divided nonwoven fabric is collected by the take-up roller to obtain nonwoven fabric of various sizes, thus completing the nonwoven fabric dividing work.

[0021] Step 5: When the take-up roller has collected enough non-woven fabric of a certain size, move the sliding plate towards the non-woven fabric so that the sliding cylinder also moves towards the non-woven fabric. The sliding cylinder drives the cutting shears to move towards the non-woven fabric, and the non-woven fabric can be cut by the cutting shears to complete the non-woven fabric collection work, so as to carry out the next non-woven fabric collection work.

[0022] Step Six: When the take-up roller has finished collecting the nonwoven fabric, start the second motor to make the second gear rotate. The rotation of the second gear causes the two toothed conveyor belts to rotate in opposite directions on the rotating roller. The two toothed conveyor belts rotate in opposite directions and slide the take-up roller off the rotating roller through the toothed rack. This allows the take-up roller that has collected enough nonwoven fabric to slide off the rotating roller, thus making it easier to remove the collected nonwoven fabric from the cutting equipment for use.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. The production apparatus and process for biodegradable nonwoven raincoat material of the present invention, wherein when cutting nonwoven fabric, the first motor is started to rotate the threaded rod, and the telescopic rod is started to push the cutting blade against the thread on the threaded rod, so that when the threaded rod rotates, the cutting blade engages with the thread on the threaded rod, and the cutting blade can move along the length direction of the threaded rod. When the cutting blade moves to the required cutting size, the telescopic rod pushes the next cutting blade. The distance and number of cutting blades can be controlled by controlling the extension and retraction of the telescopic rod, so that the cutting blade cuts the nonwoven fabric to the required size. The cut nonwoven fabric is collected by the take-up roller, and various sizes of nonwoven fabric are obtained, thus completing the nonwoven fabric cutting work.

[0025] 2. The production apparatus and process for biodegradable nonwoven raincoat material of the present invention, wherein when the sliding plate is moved toward the nonwoven fabric, the locking block will lock the sliding cylinder in the fixed cylinder, causing the sliding cylinder to slide in the sliding plate and compress the first spring through the fixed column. At this time, the sliding plate continues to move toward the nonwoven fabric, causing the first spring to be continuously compressed and applying a pushing force to the sliding cylinder. The locking block will slide out of the fixed cylinder and slide in the sliding cylinder through the second spring and the sliding column. When the locking block completely slides out of the fixed cylinder and moves into the sliding cylinder, the locking block will no longer lock the sliding cylinder. At this time, the elastic force generated by the deformation of the first spring causes the sliding cylinder to move quickly toward the nonwoven fabric. The sliding cylinder carries the cutting scissors to move quickly toward the nonwoven fabric, so that the cutting scissors can cut the nonwoven fabric better. Attached Figure Description

[0037] 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.

[0038] Example 1

[0039] like Figures 1 to 4 As shown in the embodiment of the present invention, a production device for biodegradable nonwoven raincoat material includes a dividing frame 1. Multiple transmission rollers 35 are rotatably connected between the dividing frames 1. The multiple transmission rollers 35 are used to transfer nonwoven fabric 2 for dividing. A rotating roller 28 is rotatably connected to one side of the dividing frame 1. A take-up roller 3 is provided over the rotating roller 28. The take-up roller 3 is used to collect the divided nonwoven fabric 2. Dividing grooves 4 are provided on both sides of the dividing frame 1. A rotating rod 5 is rotatably connected between two dividing grooves 4. A rotating frame 7 is fixedly connected to the rotating rod 5. A first motor 9 is fixedly connected to one side of the rotating frame 7. One end of a threaded rod 10 is fixedly connected to the output end of the first motor 9. The other end of the threaded rod 10 is rotatably connected to one side of the rotating frame 7. Multiple dividing blades 11 are threadedly connected to the threaded rod 10. A telescopic rod 8 is fixedly connected to the rotating frame 7 on one side of the first motor 9. The telescopic rod 8 is used to push the dividing blades 11.

[0040] Specifically, in the production of non-woven fabric 2 raincoats, non-woven fabric 2 needs to be cut into certain sizes for production. However, in the existing technology, the cutting size of non-woven fabric 2 is fixed. To obtain non-woven fabric 2 of other sizes, it is necessary to place it on equipment with different cutting sizes or change to cutting blades of different sizes. This is the only way to cut non-woven fabric 2 into various sizes for the production of raincoats of various sizes. This reduces the efficiency of cutting non-woven fabric 2 and increases the equipment and cost required for cutting non-woven fabric 2.

[0041] When cutting the nonwoven fabric 2 into different sizes, the nonwoven fabric 2 is placed on the drive roller 35 and the take-up roller 3. The nonwoven fabric 2 is transferred to the take-up roller 3 by the combined action of multiple drive rollers 35. The cutting and cutting of the nonwoven fabric 2 is completed during the transfer process of multiple drive rollers 35. When cutting the nonwoven fabric 2, the first motor 9 is started to rotate the threaded rod 10. Since the side of the threaded rod 10 closest to the first motor 9 has no threads, the telescopic rod 8 is an electric telescopic rod. Multiple cutting blades 11 are placed on the side of the threaded rod 10 without threads. The telescopic rod 8 is started to push the cutting blades 11 against the threaded rod 10. The threads on the threaded rod 10 abut against each other, so that when the threaded rod 10 rotates, the dividing blade 11 engages with the threads of the threaded rod 10, and the dividing blade 11 can move along the length of the threaded rod 10. When the dividing blade 11 moves to the required dividing size, the telescopic rod 8 pushes the next dividing blade 11. The distance and number of dividing blades 11 can be controlled by controlling the extension and retraction of the telescopic rod 8, so that the dividing blade 11 divides the nonwoven fabric 2 into the required size. The divided nonwoven fabric 2 is collected by the take-up roller 3, and various sizes of nonwoven fabric 2 are obtained, thus completing the dividing work of nonwoven fabric 2.

[0042] like Figure 4 As shown, a cutting device is provided on one side of the rotating rod 5 in the dividing groove 4. The cutting device includes a fixed cylinder 13 fixed to one side of the dividing groove 4, a sliding plate 14 slidably connected in the fixed cylinder 13, a sliding cylinder 15 slidably connected on the sliding plate 14, and a cutting shear 16 fixed between the two sliding cylinders 15.

[0043] Specifically, when the take-up roller 3 collects enough nonwoven fabric 2 of a certain size, the sliding plate 14 is moved towards the nonwoven fabric 2, causing the sliding cylinder 15 to also move towards the nonwoven fabric 2. The sliding cylinder 15 drives the cutting scissors 16 to move towards the nonwoven fabric 2, so that the nonwoven fabric 2 can be cut by the cutting scissors 16 to complete the collection of nonwoven fabric 2, so as to carry out the next collection of nonwoven fabric 2.

[0044] like Figure 5As shown, the cutting device also includes a sliding column 19 fixedly connected inside the sliding cylinder 15. A locking block 21 is slidably connected inside the sliding cylinder 15. The locking block 21 is slidably connected to the sliding column 19. A second spring 20 is provided on the outer sleeve of the sliding column 19. One end of the second spring 20 is fixedly connected to the sliding cylinder 15, and the other end of the second spring 20 is fixedly connected to the locking block 21. A locking groove is provided on one side of the fixed cylinder 13. The locking block 21 is locked into the locking groove. A fixed column 17 is fixedly connected to one side of the sliding plate 14. The sliding cylinder 15 is slidably connected to the fixed column 17. A first spring 18 is provided on the outer sleeve of the fixed column 17. One end of the first spring 18 is fixedly connected to the sliding plate 14, and the other end of the first spring 18 is fixedly connected to the sliding cylinder 15.

[0045] Specifically, when the sliding plate 14 is moved toward the non-woven fabric 2, the locking block 21 will lock the sliding cylinder 15 in the fixed cylinder 13, causing the sliding cylinder 15 to slide in the sliding plate 14 and compress the first spring 18 through the fixed post 17. At this time, the sliding plate 14 continues to move toward the non-woven fabric 2, causing the first spring 18 to continue to compress and apply a pushing force to the sliding cylinder 15. Since one side of the locking block 21 is set to be arc-shaped, the locking block 21 will slide out of the fixed cylinder 13 and slide in the sliding cylinder 15 through the second spring 20 and the sliding post 19. When the locking block 21 completely slides out of the fixed cylinder 13 and moves into the sliding cylinder 15, the locking block 21 will no longer lock the sliding cylinder 15. At this time, the elastic force generated by the deformation of the first spring 18 causes the sliding cylinder 15 to move quickly toward the non-woven fabric 2. The sliding cylinder 15 carries the cutting scissors 16 to move quickly toward the non-woven fabric 2, so that the cutting scissors 16 can cut the non-woven fabric 2 better.

[0046] like Figure 4 As shown, the cutting device also includes a toothed plate 12 fixed to the bottom of the sliding plate 14. The toothed plate 12 is slidably connected to the fixed cylinder 13. The rotating rod 5 is fixed to both sides with a first gear 6, and the two first gears 6 are respectively meshed with the toothed plate 12.

[0047] Specifically, when the sliding plate 14 is moved toward the non-woven fabric 2, the first gear 6 is rotated by rotating the rotating rod 5, the first gear 6 moves the toothed plate 12, and the sliding plate 14 moves toward the non-woven fabric 2 by the toothed plate 12.

[0048] like Figure 3 As shown, the dividing frame 1 is fixed to one side of the cutting scissors 16 with a cutting block 22, and a cutting opening is provided on one side of the cutting block 22.

[0049] Specifically, when the cutting scissors 16 cuts the non-woven fabric 2, the cutting scissors 16, which move quickly toward the non-woven fabric 2, will hit the cutting opening of the cutting block 22, thus completing the cutting of the non-woven fabric 2 and pressing the non-woven fabric 2 into the cutting block 22 so that the non-woven fabric 2 can be rolled up again.

[0050] like Figure 7 As shown, one end of the rotating rod 5 passes through the dividing frame 1 and is fitted with a rotating cylinder 25. Both sides of the rotating cylinder 25 are fixedly connected with insert blocks 24. The dividing frame 1 has two insertion holes 36, and the two insert blocks 24 are slidably connected to the insertion holes 36 respectively.

[0051] Specifically, when rotating the rotating rod 5, the rotating cylinder 25 is slid away from the dividing frame 1 to make the insert block 24 slide out of the insertion hole 36. Then, rotating the rotating cylinder 25 will make the rotating rod 5 rotate. The rotation of the rotating rod 5 cancels the dividing effect of the dividing knife 11 on the non-woven fabric 2, and allows the cutting scissors 16 to cut the non-woven fabric 2 to complete the winding.

[0052] like Figure 7 As shown, two sliders 26 are fixedly connected to one side of the rotating rod 5 inside the rotating cylinder 25. Two grooves 27 are opened inside the rotating cylinder 25, and the two sliders 26 are slidably connected to the grooves 27.

[0053] Specifically, the slider 26 slides within the groove 27, causing the rotating cylinder 25 to slide and rotate on the rotating rod 5. This limits the sliding of the rotating cylinder 25 on the rotating rod 5, allowing the rotating cylinder 25 to slide and rotate better on the rotating rod 5.

[0054] like Figure 9 As shown, toothed rollers 29 are fixedly connected to both sides of the take-up roller 3, and toothed conveyor belts 30 are rotatably connected to both sides of the rotating roller 28. A second motor 31 is fixedly connected to the rotating roller 28 between the two toothed conveyor belts 30, and a second gear 32 is fixedly connected to the output end of the second motor 31.

[0055] Specifically, when the take-up roller 3 finishes collecting the nonwoven fabric 2, the second motor 31 is started to make the second gear 32 rotate. The rotation of the second gear 32 causes the two toothed conveyor belts 30 to rotate in opposite directions on the rotating roller 28. The two toothed conveyor belts 30 rotate in opposite directions and slide the take-up roller 3 off the rotating roller 28 through the toothed rack 29. This allows the take-up roller 3, which has collected enough nonwoven fabric 2, to slide off the rotating roller 28, thus making it easier to remove the collected nonwoven fabric 2 from the cutting device for use.

[0056] like Figure 3 As shown, the dividing frame 1 is provided with a transfer roller 33 on the lower side of the take-up roller 3, and the dividing frame 1 is provided with a movable plate 34 on one side of the transfer roller 33. The movable plate 34 is slidably connected to the dividing frame 1 through a slide rail.

[0057] Specifically, when the take-up roller 3 that has collected enough nonwoven fabric 2 is removed, the sliding plate 34 is moved by the slide rail, and the transfer roller 33 receives the collected nonwoven fabric 2. At this time, the second motor 31 is started so that the take-up roller 3 that has collected enough nonwoven fabric 2 can slide out of the rotating roller 28 and the cut nonwoven fabric 2 can be removed from the cutting device.

[0058] Example 2

[0059] like Figures 1 to 9 As shown in Example 1, another embodiment of the present invention is as follows:

[0060] Step 1: Select suitable fiber materials, pre-treat the raw fiber materials, and break the fibers by melting or shearing and then combining them.

[0061] Step 2: The broken fibers are laid out into a web using methods such as wet, dry, or hot air methods to evenly distribute the fibers on the web laying machine.

[0062] Step 3: The fibers after the web is laid are further heated and heat-set to make the fibers bond together. During the production process, dyes, coatings or other treatments may be added to the non-woven fabric 2 to meet specific needs. After processing, the finished non-woven fabric 2 is wound or cut.

[0063] Step 4: Place the nonwoven fabric 2 on the drive roller 35 and the take-up roller 3. The nonwoven fabric 2 is transferred to the take-up roller 3 through the combined action of multiple drive rollers 35. During the transfer process of multiple drive rollers 35, the cutting and segmentation of the nonwoven fabric 2 is completed. When segmenting the nonwoven fabric 2, start the first motor 9 to rotate the threaded rod 10. Start the telescopic rod 8 to push the segmenting knife 11 to abut against the thread on the threaded rod 10. When the threaded rod 10 rotates, the segmenting knife 11 engages with the thread on the threaded rod 10. The segmenting knife 11 can then move along the length of the threaded rod 10. When the segmenting knife 11 moves to the required segmentation size, the telescopic rod 8 pushes the next segmenting knife 11. The distance and number of segmenting knives 11 can be controlled by controlling the extension and retraction of the telescopic rod 8, so that the segmenting knife 11 can segment the nonwoven fabric 2 to the required size. The segmented nonwoven fabric 2 is collected by the take-up roller 3 to obtain nonwoven fabric 2 of various sizes, thus completing the segmentation of the nonwoven fabric 2.

[0064] Step 5: When the take-up roller 3 has collected enough non-woven fabric 2 of a certain size, move the sliding plate 14 towards the non-woven fabric 2 so that the sliding cylinder 15 also moves towards the non-woven fabric 2. The sliding cylinder 15 drives the cutting scissors 16 to move towards the non-woven fabric 2, so that the non-woven fabric 2 can be cut by the cutting scissors 16 to complete the collection of non-woven fabric 2, so as to carry out the next collection of non-woven fabric 2.

[0065] Step Six: When the take-up roller 3 finishes collecting the nonwoven fabric 2, start the second motor 31 to make the second gear 32 rotate. The rotation of the second gear 32 causes the two toothed conveyor belts 30 to rotate in opposite directions on the rotating roller 28. The two toothed conveyor belts 30 rotate in opposite directions and slide the take-up roller 3 off the rotating roller 28 through the toothed rack 29. This allows the take-up roller 3, which has collected enough nonwoven fabric 2, to slide off the rotating roller 28, thus making it easier to remove the collected nonwoven fabric 2 from the cutting device for use.

[0066] Working principle: When cutting nonwoven fabric 2 into different sizes, nonwoven fabric 2 is placed on drive roller 35 and take-up roller 3. Through the combined action of multiple drive rollers 35, nonwoven fabric 2 is transferred to take-up roller 3. During the transfer process of multiple drive rollers 35, the cutting and cutting of nonwoven fabric 2 is completed. When cutting nonwoven fabric 2, the first motor 9 is started to rotate the threaded rod 10. Since the side of the threaded rod 10 closest to the first motor 9 has no thread, the telescopic rod 8 is an electric telescopic rod. Multiple cutting blades 11 are placed on the side of the threaded rod 10 without threads. The telescopic rod 8 is started to push the cutting blades 11. The dividing blade 11 engages with the thread on the threaded rod 10 when the threaded rod 10 rotates, allowing the dividing blade 11 to move along the length of the threaded rod 10. When the dividing blade 11 reaches the desired dividing size, the telescopic rod 8 pushes the next dividing blade 11. The distance and number of dividing blades 11 can be controlled by extending and retracting the telescopic rod 8, thus allowing the dividing blade 11 to divide the nonwoven fabric 2 into the desired size. The divided nonwoven fabric 2 is then collected by the take-up roller 3, thus obtaining nonwoven fabric 2 of various sizes and completing the dividing work of nonwoven fabric 2.

[0067] When the take-up roller 3 collects enough nonwoven fabric 2 of a certain size, the sliding plate 14 moves towards the nonwoven fabric 2, causing the sliding cylinder 15 to also move towards the nonwoven fabric 2. The sliding cylinder 15 drives the cutting shears 16 to move towards the nonwoven fabric 2, thus cutting the nonwoven fabric 2 with the cutting shears 16 to complete the collection of the nonwoven fabric 2, so as to proceed with the next collection of nonwoven fabric 2. When the sliding plate 14 moves towards the nonwoven fabric 2, the locking block 21 will lock the sliding cylinder 15 in the fixed cylinder 13, causing the sliding cylinder 15 to slide within the sliding plate 14 and pass through. As the first spring 18 is compressed by the fixed post 17, the sliding plate 14 continues to move closer to the nonwoven fabric 2, causing the first spring 18 to be continuously compressed and applying a pushing force to the sliding cylinder 15. Since one side of the locking block 21 is arc-shaped, the locking block 21 will slide out of the fixed cylinder 13 and slide inside the sliding cylinder 15 via the second spring 20 and the sliding post 19. When the locking block 21 has completely slid out of the fixed cylinder 13 and moved into the sliding cylinder 15, the locking block 21 will no longer lock the sliding cylinder 15. At this time, the elastic force generated by the deformation of the first spring 18 causes the sliding cylinder 15 to quickly move towards the nonwoven fabric 2. The sliding cylinder 15 moves rapidly towards the nonwoven fabric 2, carrying the cutting scissors 16, allowing the cutting scissors 16 to cut the nonwoven fabric 2 more effectively. Rotating the rotating rod 5 causes the first gear 6 to rotate, which in turn moves the toothed plate 12, causing the sliding plate 14 to move closer to the nonwoven fabric 2. When the cutting scissors 16 cuts the nonwoven fabric 2, the rapidly moving cutting scissors 16 impacts the cutting opening of the cutting block 22, completing the cutting of the nonwoven fabric 2 and pressing it against the cutting block 22 for better cutting. The non-woven fabric 2 is wound up again; when the rotating rod 5 is rotated, the rotating cylinder 25 is slid away from the dividing frame 1 to make the insert block 24 slide out of the insertion hole 36. Then, rotating the rotating cylinder 25 will make the rotating rod 5 rotate. The rotation of the rotating rod 5 cancels the dividing effect of the dividing knife 11 on the non-woven fabric 2 and allows the cutting scissors 16 to cut the non-woven fabric 2 to complete the winding. The rotating cylinder 25 slides and rotates on the rotating rod 5 by sliding the slider 26 in the groove 27. The sliding of the rotating cylinder 25 on the rotating rod 5 is limited so that the rotating cylinder 25 can slide and rotate better on the rotating rod 5.

[0068] When the take-up roller 3 finishes collecting the nonwoven fabric 2, the second motor 31 is started to rotate the second gear 32. The rotation of the second gear 32 causes the two toothed conveyor belts 30 to rotate in opposite directions on the rotating roller 28. The two toothed conveyor belts 30 rotate in opposite directions and slide the take-up roller 3 off the rotating roller 28 through the toothed rack 29. This allows the take-up roller 3, which has collected enough nonwoven fabric 2, to slide off the rotating roller 28, thus making it easier to remove the collected nonwoven fabric 2 from the cutting device for use. When the take-up roller 3, which has collected enough nonwoven fabric 2, is removed, the sliding plate 34 is moved by the slide rail. The transfer roller 33 receives the collected nonwoven fabric 2 at this time. At this time, the second motor 31 is started to make the take-up roller 3, which has collected enough nonwoven fabric 2, slide off the rotating roller 28, and remove the cut nonwoven fabric 2 from the cutting device.

[0069] Step 1: Select suitable fiber materials, pre-treat the raw fiber materials, and break the fibers by melting or shearing and then combining them.

[0070] Step 2: The broken fibers are laid out into a web using methods such as wet, dry, or hot air methods to evenly distribute the fibers on the web laying machine.

[0071] Step 3: The fibers after the web is laid are further heated and heat-set to make the fibers bond together. During the production process, dyes, coatings or other treatments may be added to the non-woven fabric 2 to meet specific needs. After processing, the finished non-woven fabric 2 is wound or cut.

[0072] Step 4: Place the nonwoven fabric 2 on the drive roller 35 and the take-up roller 3. The nonwoven fabric 2 is transferred to the take-up roller 3 through the combined action of multiple drive rollers 35. During the transfer process of multiple drive rollers 35, the cutting and segmentation of the nonwoven fabric 2 is completed. When segmenting the nonwoven fabric 2, start the first motor 9 to rotate the threaded rod 10. Start the telescopic rod 8 to push the segmenting knife 11 to abut against the thread on the threaded rod 10. When the threaded rod 10 rotates, the segmenting knife 11 engages with the thread on the threaded rod 10. The segmenting knife 11 can then move along the length of the threaded rod 10. When the segmenting knife 11 moves to the required segmentation size, the telescopic rod 8 pushes the next segmenting knife 11. The distance and number of segmenting knives 11 can be controlled by controlling the extension and retraction of the telescopic rod 8, so that the segmenting knife 11 can segment the nonwoven fabric 2 to the required size. The segmented nonwoven fabric 2 is collected by the take-up roller 3 to obtain nonwoven fabric 2 of various sizes, thus completing the segmentation of the nonwoven fabric 2.

[0073] Step 5: When the take-up roller 3 has collected enough non-woven fabric 2 of a certain size, move the sliding plate 14 towards the non-woven fabric 2 so that the sliding cylinder 15 also moves towards the non-woven fabric 2. The sliding cylinder 15 drives the cutting scissors 16 to move towards the non-woven fabric 2, so that the non-woven fabric 2 can be cut by the cutting scissors 16 to complete the collection of non-woven fabric 2, so as to carry out the next collection of non-woven fabric 2.

[0074] Step Six: When the take-up roller 3 finishes collecting the nonwoven fabric 2, start the second motor 31 to make the second gear 32 rotate. The rotation of the second gear 32 causes the two toothed conveyor belts 30 to rotate in opposite directions on the rotating roller 28. The two toothed conveyor belts 30 rotate in opposite directions and slide the take-up roller 3 off the rotating roller 28 through the toothed rack 29. This allows the take-up roller 3, which has collected enough nonwoven fabric 2, to slide off the rotating roller 28, thus making it easier to remove the collected nonwoven fabric 2 from the cutting device for use.
