Description

Technical Field

[0001] The invention relates to the technical field of cotton web processing equipment, in particular to a cotton pressing device for a non-woven fiber cotton web. Background Art

[0002] Non-woven fiber cotton web (also called non-woven cotton web) is a material that uses non-woven fabric technology to process cotton or other fiber raw materials into a mesh structure. It does not require a weaving process, but directly connects the fibers into a web through physical, chemical or mechanical methods to form a non-woven fabric. Non-woven cotton web is widely used in all walks of life, especially in the fields of hygiene, medicine, filtration, packaging, automobiles, homes, etc.

[0003] Among them, the common cotton pressing method often uses a pressing roller to squeeze the cotton web, but the amount of fiber distribution in each area of ​​the cotton web may be different, which may cause some areas to be thicker and some areas to be thinner when the pressing roller presses the cotton web, which may make the thickness of the cotton web uneven. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a non-woven fiber cotton web pressing device, including a conveyor, the left and right sides of the conveyor are fixedly connected with fixed blocks, the inner walls of the two fixed blocks are rotatably connected with two rotating rods, the right side of the fixed block located on the right side is fixedly connected with a motor, the output end of the motor at the side wall is fixedly connected to the right side of the rotating rod located at the top, the outer walls of the two rotating rods are fixedly connected with two sliders, the left side of the fixed block on the right side is provided with two pressing rollers, the inner walls of the two pressing rollers are slidably connected with the outer wall of the slider, the outer walls of the two rotating rods are fixedly connected with pulleys, the outer walls of the two pulleys are sleeved with belts, and the tops of the fixed blocks are fixedly connected with extrusion components; The reciprocating mechanism includes two concave-convex rings fixedly connected to the side wall of the left fixed block, six fixed rods fixedly connected to the side walls of the two pressure rollers, the side walls of the six fixed rods are slidably connected to the side walls of the concave-convex rings, and the outer walls of the two rotating rods are slidably connected to spring return rings; The rubbing mechanism includes a sliding frame arranged on the outer wall of the pressure roller, thirteen rollers are rotatably connected on the inner walls of the two sliding frames, annular grooves are opened on the outer walls of the two pressure rollers, two connecting rods are fixedly connected on the sides of the two sliding frames away from each other, the outer walls of the four connecting rods are rotatably connected to the inner wall of the annular groove, the left and right sides of the two sliding frames are fixedly connected with sliding rods, the outer walls of the four sliding rods are slidably connected to the inner wall of the fixed block, and a beating assembly is fixedly connected to the top of the fixed block. When in use, the cotton web is transported to the position of the pressure roller through the conveyor so that the cotton web is squeezed by the pressure roller, and then the motor is started to drive the rotating rod to rotate, the pulley rotates, and the belt rotates, so that the two rotating rods rotate at the same time, and the rotating rod drives the pressure roller to rotate through the slider to squeeze the cotton web. When the pressure roller rotates, it also drives the fixed rod to rotate. When the fixed rod moves from the concave and convex ring When the pressing roller moves toward the motor, it will also drive the connecting rod to move through the annular groove, allowing the sliding frame to move and the roller to roll on the cotton net. When the fixed rod moves from the convex position of the concave and convex ring to the concave position again, the rebound force of the spring reset ring will be released, allowing the pressing roller to return to its position. This reciprocating process will allow the pressing roller and the roller to squeeze the cotton net and rub the cotton net. When the pressing roller and the roller contact the thicker area of ​​the cotton net, the thicker area is in closer contact with the pressing roller and the roller. Therefore, the friction between the two is greater, which can push the fibers to move to the thinner area of ​​the cotton net, so that the fibers in the cotton net can be further evenly distributed, the local concentration of fibers can be reduced, and the uneven thickness of the cotton net can be effectively prevented.

[0005] Preferably, the extrusion assembly includes a fixed plate 1 fixedly connected to the top and bottom of the fixed block, an extrusion plate is provided at the side walls of the two fixed blocks, two sliding rods 2 are fixedly connected to the side walls of the two extrusion plates, the outer walls of the four sliding rods 1 are slidably connected to the inner walls of the extrusion plate, and the outer walls of the two sliding rods 2 are slidably connected to the inner walls of the fixed block.

[0006] Preferably, the extrusion assembly also includes a connecting plate arranged on the side of the fixed plate close to the pressure roller, connecting rings are fixedly connected to the outer walls of the six fixed rods, and the tops and bottoms of the two extrusion plates are rotatably connected to four connecting rods. The sides of the two connecting plates close to the extrusion plates are rotatably connected to the inner walls of the connecting rods. When the fixed rod moves toward the direction of the motor, the connecting ring will also be driven to move, and the connecting ring will contact the extrusion plate, pushing the extrusion plate on the left side close to the cotton net, allowing the connecting rod to rotate and fold, pushing up the connecting plate, and moving the connecting plate away from the pressure roller.

[0007] Preferably, the extrusion assembly also includes a spring return rod 1 fixedly connected to the side of the connecting plate away from each other, and the outer walls of the two spring return rods 1 are slidably connected to the inner wall of the fixed plate 1. When the spring return rod 1 is squeezed, the connecting rod on the right side will rotate, allowing the extrusion plate on the right side to approach the cotton net, so that the two extrusion plates squeeze both sides of the cotton net.

[0008] Preferably, the beating assembly includes two fixed plates 2 fixedly connected to the top and bottom of the fixed block, the inner walls of the eight fixed plates 2 are slidably connected with spring return rods 2, and the side walls of the two extrusion plates are provided with beating plates, the sides of the eight beating plates away from each other are fixedly connected with the sides of the eight spring return rods 2 close to each other, and the inner walls of the eight beating plates are slidably connected with spring plates, and when the extrusion plates move toward the cotton net, they will contact and squeeze the spring plates, and the two sides of the cotton net will be pressed tightly by the cooperation of the beating plates and the spring plates.

[0009] Preferably, the beating assembly also includes a raised rod fixedly connected to the side of the beating plates away from each other, four concave-convex plates are fixedly connected to the side walls of the two extrusion plates, and the sides of the eight concave-convex plates close to each other are slidably connected to the sides of the eight raised rods away from each other. When the extrusion plate moves, it will also drive the concave-convex plate to move, so that the contact surface between the concave-convex plate and the raised rod, when the concave-convex plate moves from a recessed position to a protruding position, will squeeze the raised rod, so that the raised rod is close to the cotton net, driving the beating plate to move, and the top of the cotton net will be squeezed.

[0010] Preferably, the flapping assembly also includes a fixed frame fixedly connected to the two side walls of the fixed plate, and sliding plates are slidably connected to the inner walls of the four fixed frames. The four sliding plates are fixedly connected to two connecting rods 2 on one side close to the flapping plate, and the eight connecting rods 2 on one side away from the sliding plate are fixedly connected to the side of the flapping plate close to the fixed frame. When the flapping plate moves toward the cotton net, the connecting rods 2 will be driven to move, thereby allowing the sliding plate to approach the cotton net. At this time, the sliding plate will squeeze the gas in the fixed frame.

[0011] Preferably, the beating assembly also includes a spring blocking plate slidably connected to the inner wall of the fixed frame, and the four sliding plates are fixedly connected to a push plate on one side close to the spring blocking plate, and the four fixed frames are fixedly connected to a jet plate on one side close to the pressure roller. The squeezed gas will be blocked by the spring blocking plate, thereby increasing the pressure of the gas. As the spring blocking plate continues to move, the push plate will contact the spring blocking plate, pushing the spring blocking plate down, allowing the spring blocking plate to accumulate rebound force. When the spring blocking plate descends, the jet plate will be connected to the inside of the fixed frame, and the high-pressure gas will be ejected from the jet plate toward the surface of the pressure roller, causing the fibers attached to the surface of the pressure roller to fall off.

[0012] The present invention has the following beneficial effects: (1) When the present invention is used, the cotton web is conveyed to the position of the pressure roller by the conveyor, so that the cotton web is squeezed by the pressure roller, and then the motor is started to drive the rotating rod to rotate, so that the pulley rotates, and the belt rotates, so that the two rotating rods rotate at the same time, and the rotating rod drives the pressure roller to rotate through the slider to squeeze the cotton web. When the pressure roller rotates, it also drives the fixed rod to rotate. When the fixed rod moves from the concave position of the concave-convex ring to the convex position, the fixed rod is squeezed, so that the fixed rod moves toward the direction of the motor, driving the pressure roller to move, and at the same time squeezing the spring reset ring, so that the spring reset ring accumulates resilience. When the pressure roller moves toward the motor, it will also pass through the annular groove. The connecting rod is driven to move, the sliding frame is moved, and the roller is rolled on the cotton net. When the fixed rod moves from the protruding position of the concave-convex ring to the concave position again, the resilience of the spring reset ring will be released, allowing the pressure roller to return to its position. This reciprocating process will allow the pressure roller and the roller to squeeze the cotton net while rubbing the cotton net. When the pressure roller and the roller contact the thicker area of ​​the cotton net, the thicker area is in closer contact with the pressure roller and the roller, so the friction between the two is greater, which can push the fibers to move to the thinner area of ​​the cotton net, thereby making the fibers in the cotton net more evenly distributed, reducing local concentration of fibers, and effectively preventing uneven thickness of the cotton net.

[0013] (2) When the fixed rod of the present invention moves toward the direction of the motor, it will also drive the connecting ring to move. The connecting ring will then contact the extrusion plate, pushing the extrusion plate on the left side close to the cotton net, causing the connecting rod to rotate and fold, lifting the connecting plate, and moving the connecting plate away from the pressure roller. Once the spring return rod is squeezed, the connecting rod on the right side will rotate, causing the extrusion plate on the right side to approach the cotton net, so that the two extrusion plates will squeeze the two sides of the cotton net. As the connecting ring continues to move toward the direction of the motor, the extrusion plate will also continue to squeeze the cotton net, allowing the extrusion plate to gradually increase the extrusion force following the rubbing amplitude of the pressure roller and the roller, effectively preventing the cotton net from being unevenly compressed due to the increase in width during the rubbing process.

[0014] (3) When the extrusion plate moves toward the cotton net, the present invention will contact the spring plate and squeeze the spring plate. The two sides of the cotton net are pressed tightly by the cooperation of the slapping plate and the spring plate. When the extrusion plate moves, it will also drive the concave-convex plate to move, so that the contact surface between the concave-convex plate and the raised rod, when the concave-convex plate moves from the concave position to the convex position, it will squeeze the raised rod, so that the raised rod is close to the cotton net, driving the slapping plate to move, and at the same time allowing the spring reset rod 2 to accumulate rebound force. When the slapping plate moves, it will squeeze the top of the cotton net. When the contact surface between the concave-convex plate and the raised rod moves from convex to concave, the rebound force of the spring reset rod 2 will be released, allowing the slapping plate to return to its position. This reciprocating process will cause the slapping plate to slap the bottom of the cotton net, effectively preventing the two sides of the cotton net from being squeezed, increasing the thickness of the two sides of the cotton net, and making the overall thickness of the cotton net uniform.

[0015] (4) When the flapping plate moves toward the cotton net, the second connecting rod will be driven to move, so that the sliding plate will approach the cotton net. At this time, the sliding plate will squeeze the gas in the fixed frame. The squeezed gas will be blocked by the spring blocking plate, so that the pressure of the gas will increase. As the spring blocking plate continues to move, the pushing plate will contact the spring blocking plate, pushing the spring blocking plate down, allowing the spring blocking plate to accumulate rebound force. When the spring blocking plate descends, the jet plate will be connected to the inside of the fixed frame. The high-pressure gas will be sprayed from the jet plate to the surface of the pressure roller, so that the fibers attached to the surface of the pressure roller will fall off, avoiding the pressure roller from rubbing the cotton net, resulting in an increase in the friction between the two, and the fibers may be attached to the pressure roller. It is effective to prevent too much fiber from being attached to the pressure roller, resulting in uneven thickness at the outer wall of the pressure roller, affecting the compaction effect.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] For example, see Figure 1-Figure 5 The present invention is a non-woven fiber web pressing device, comprising a conveyor 1, a fixed block 11 is fixedly connected to the left and right sides of the conveyor 1, two rotating rods 13 are rotatably connected to the inner walls of the two fixed blocks 11, a motor 12 is fixedly connected to the right side of the fixed block 11 on the right side, an output end at the side wall of the motor 12 is fixedly connected to the right side of the rotating rod 13 at the top, two sliders 131 are fixedly connected to the outer walls of the two rotating rods 13, two pressing rollers 14 are arranged on the left side of the right fixed block 11, the inner walls of the two pressing rollers 14 are slidably connected to the outer walls of the sliders 131, pulleys 15 are fixedly connected to the outer walls of the two rotating rods 13, belts 16 are sleeved on the outer walls of the two pulleys 15, and a pressing assembly 4 is fixedly connected to the top of the fixed block 11; The reciprocating mechanism 2 includes two concave-convex rings 21 fixedly connected to the side wall of the left fixed block 11, six fixed rods 22 are fixedly connected to the side walls of the two pressure rollers 14, the side walls of the six fixed rods 22 are slidably connected to the side walls of the concave-convex rings 21, and the outer walls of the two rotating rods 13 are slidably connected to the spring return rings 23; The rubbing mechanism 3 includes a sliding frame 31 arranged on the outer wall of the pressure roller 14, and the inner walls of the two sliding frames 31 are rotatably connected to thirteen rollers 32. The outer walls of the two pressure rollers 14 are provided with an annular groove 33. The two sliding frames 31 are fixedly connected to two connecting rods 34 on the side away from each other. The outer walls of the four connecting rods 34 are rotatably connected to the inner wall of the annular groove 33. The left and right sides of the two sliding frames 31 are fixedly connected to sliding rods 35. The outer walls of the four sliding rods 35 are fixedly connected to the inner wall of the annular groove 33. The cotton web is conveyed to the position of the pressing roller 14 through the conveyor 1, and the cotton web is squeezed by the pressing roller 14. Then the motor 12 is started to drive the rotating rod 13 to rotate, and the pulley 15 is rotated to rotate the belt 16, so that the two rotating rods 13 rotate at the same time. The rotating rod 13 drives the pressing roller 14 to rotate through the slider 131 to squeeze the cotton web. When the pressing roller 14 rotates, it also drives the fixed rod 22 to rotate. When the rod 22 moves from the concave position of the concave-convex ring 21 to the convex position, the fixed rod 22 is squeezed, so that the fixed rod 22 moves toward the direction of the motor 12, driving the pressure roller 14 to move, and at the same time squeezing the spring return ring 23, so that the spring return ring 23 accumulates resilience. When the pressure roller 14 moves toward the motor 12, it also drives the connecting rod 34 to move through the annular groove 33, so that the sliding frame 31 moves, and the roller 32 rolls on the cotton net. When the fixed rod 22 moves from the convex position of the concave-convex ring 21 to the concave position again, The resilience of the spring return ring 23 will be released, allowing the pressure roller 14 to return to its original position. This reciprocating movement will allow the pressure roller 14 and the roller 32 to squeeze the cotton web and rub the cotton web. When the pressure roller 14 and the roller 32 are in contact with the thicker area of ​​the cotton web, the thicker area is in closer contact with the pressure roller 14 and the roller 32. Therefore, the friction between the two is greater, which can push the fibers to move to the thinner area of ​​the cotton web, making the fibers in the cotton web more evenly distributed, reducing local concentration of fibers, and effectively preventing uneven thickness of the cotton web.

[0021] For example 2, please refer to Figure 6-Figure 9 The present invention is a non-woven fiber cotton web pressing device. On the basis of Example 1, the pressing component 4 includes a fixed plate 41 fixedly connected to the top and bottom of the fixed block 11, and the side walls of the two fixed blocks 11 are provided with pressing plates 42. The side walls of the two pressing plates 42 are fixedly connected with two sliding rods 421, and the outer walls of the four sliding rods 35 are slidably connected to the inner walls of the pressing plates 42, and the outer walls of the two sliding rods 421 are slidably connected to the inner walls of the fixed block 11.

[0022] The extrusion assembly 4 also includes a connecting plate 44 arranged on the side of the fixed plate 41 close to the pressure roller 14, and a connecting ring 43 is fixedly connected to the outer wall of the six fixed rods 22. The top and bottom of the two extrusion plates 42 are rotatably connected to four connecting rods 45. The side of the two connecting plates 44 close to the extrusion plate 42 is rotatably connected to the inner wall of the connecting rod 45. When the fixed rod 22 moves toward the direction of the motor 12, it will also drive the connecting ring 43 to move, and the connecting ring 43 will contact the extrusion plate 42, pushing the extrusion plate 42 on the left side close to the cotton net, allowing the connecting rod 45 to rotate and fold, and push up the connecting plate 44, so that the connecting plate 44 is away from the pressure roller 14.

[0023] The extrusion assembly 4 also includes a spring return rod 46 fixedly connected to the side of the connecting plate 44 away from each other. The outer walls of the two spring return rods 46 are slidably connected to the inner wall of the fixed plate 41. When the spring return rod 46 is squeezed, the connecting rod 45 on the right side will rotate, allowing the extrusion plate 42 on the right side to approach the cotton net, so that the two extrusion plates 42 squeeze the two sides of the cotton net.

[0024] The beating assembly 5 includes two fixed plates 51 fixedly connected to the top and bottom of the fixed block 11, and the inner walls of the eight fixed plates 51 are slidably connected with spring return rods 52. A beating plate 53 is provided on the side walls of the two extrusion plates 42. The sides of the eight beating plates 53 that are away from each other are fixedly connected to the sides of the eight spring return rods 52 that are close to each other. The inner walls of the eight beating plates 53 are slidably connected with spring plates 54. When the extrusion plate 42 moves toward the cotton net, it will contact the spring plate 54 to squeeze the spring plate 54, and the two sides of the cotton net are pressed tightly by the cooperation of the beating plate 53 and the spring plate 54.

[0025] The beating assembly 5 also includes a raised rod 531 fixedly connected to the side of the beating plate 53 that is away from each other. Four concave-convex plates 55 are fixedly connected to the side walls of the two extrusion plates 42. The sides of the eight concave-convex plates 55 that are close to each other are slidably connected to the sides of the eight raised rods 531 that are away from each other. When the extrusion plate 42 moves, it will also drive the concave-convex plate 55 to move, so that the contact surface between the concave-convex plate 55 and the raised rod 531, when the concave-convex plate 55 moves from a recessed position to a protruding position, it will squeeze the raised rod 531, so that the raised rod 531 is close to the cotton net, driving the beating plate 53 to move, and the top of the cotton net will be squeezed.

[0026] The beating assembly 5 also includes a fixed frame 57 fixedly connected to the side wall of the fixed plate 2 51, and the inner walls of the four fixed frames 57 are slidably connected with sliding plates 571. The four sliding plates 571 are fixedly connected to two connecting rods 2 56 on the side close to the beating plate 53, and the sides of the eight connecting rods 2 56 away from the sliding plate 571 are fixedly connected to the side of the beating plate 53 close to the fixed frame 57. When the beating plate 53 moves toward the cotton net, it will drive the connecting rod 2 56 to move, so that the sliding plate 571 is close to the cotton net. At this time, the sliding plate 571 will squeeze the gas in the fixed frame 57.

[0027] The beating assembly 5 also includes a spring blocking plate 572 slidably connected to the inner wall of the fixed frame 57, and the four sliding plates 571 are fixedly connected to the side close to the spring blocking plate 572 with a pushing plate 573, and the four fixed frames 57 are fixedly connected to the side close to the pressure roller 14 with a jet plate 58. The squeezed gas will be blocked by the spring blocking plate 572, thereby increasing the pressure of the gas. As the spring blocking plate 572 continues to move, the pushing plate 573 will contact the spring blocking plate 572, pushing the spring blocking plate 572 down, allowing the spring blocking plate 572 to accumulate rebound force. When the spring blocking plate 572 descends, the jet plate 58 will be connected to the inside of the fixed frame 57, and the high-pressure gas will be ejected from the jet plate 58 toward the surface of the pressure roller 14, allowing the fibers attached to the surface of the pressure roller 14 to fall off.

[0028] There is no limitation on the number of the above components, and relevant technicians in the field can freely set them according to actual needs, as long as the above components are installed at the connection positions of the corresponding components.

[0029] A specific application of this embodiment is as follows: when the present invention is used, the cotton web is conveyed to the position of the pressure roller 14 through the conveyor 1, so that the cotton web is squeezed by the pressure roller 14, and then the motor 12 is started to drive the rotating rod 13 to rotate, so that the pulley 15 rotates, and the belt 16 rotates, so that the two rotating rods 13 rotate at the same time, and the rotating rod 13 drives the pressure roller 14 to rotate through the slider 131 to squeeze the cotton web. When the pressure roller 14 rotates, it also drives the fixed rod 22 to rotate. When the fixed rod 22 moves from the concave position of the concave-convex ring 21 to the convex position, the fixed rod 22 is squeezed, so that the fixed rod 22 moves toward the direction of the motor 12, driving the pressure roller 14 to move, and at the same time squeezing the spring return ring 23, so that the spring return ring 23 accumulates resilience, and the pressure roller 14 moves toward the motor 12. When the machine 12 moves, the annular groove 33 will also drive the connecting rod 34 to move, so that the sliding frame 31 moves and the roller 32 rolls on the cotton net. When the fixed rod 22 moves from the convex position of the concave-convex ring 21 to the concave position again, the resilience of the spring return ring 23 will be released, so that the pressure roller 14 and the roller 32 can squeeze the cotton net and rub the cotton net. When the pressure roller 14 and the roller 32 are in contact with the thicker area of ​​the cotton net, the thicker area is in closer contact with the pressure roller 14 and the roller 32, so the friction between the two is greater, which can push the fibers to move to the thinner area of ​​the cotton net, so that the fibers in the cotton net can be further evenly distributed, the local concentration of fibers can be reduced, and the uneven thickness of the cotton net can be effectively prevented. Secondly, when the fixing rod 22 moves toward the direction of the motor 12, it will also drive the connecting ring 43 to move, and the connecting ring 43 will contact the extrusion plate 42, pushing the extrusion plate 42 on the left side close to the cotton net, allowing the connecting rod 45 to rotate and fold, and lift the connecting plate 44, so that the connecting plate 44 is away from the pressure roller 14, and the spring return rod 46 is squeezed, which will make the connecting rod 45 on the right side rotate, so that the extrusion plate 42 on the right side is close to the cotton net, so that the two extrusion plates 42 squeeze the two sides of the cotton net. As the connecting ring 43 continues to move toward the direction of the motor 12, the extrusion plate 42 will also continue to squeeze the cotton net, so that the extrusion plate 42 can gradually increase the extrusion force following the rubbing amplitude of the pressure roller 14 and the roller 32, effectively preventing the cotton net from being unevenly compressed due to the increase in width during the rubbing process; Secondly, when the squeezing plate 42 moves toward the cotton net, it will contact the spring plate 54 and squeeze the spring plate 54. The two sides of the cotton net are pressed tightly by the slapping plate 53 and the spring plate 54. When the squeezing plate 42 moves, it will also drive the concave-convex plate 55 to move, so that the contact surface between the concave-convex plate 55 and the protruding rod 531, when the concave-convex plate 55 moves from the concave position to the protruding position, it will squeeze the protruding rod 531, so that the protruding rod 531 is close to the cotton net, driving the slapping plate 53 to move. When the plate 53 moves, the spring return rod 52 accumulates the resilience. When the beating plate 53 moves, the top of the cotton net is squeezed. When the contact surface between the concave-convex plate 55 and the protruding rod 531 moves from convex to concave, the resilience of the spring return rod 52 is released, so that the beating plate 53 returns to its original position. In this way, the beating plate 53 beats the bottom of the cotton net, effectively preventing the two sides of the cotton net from being squeezed, increasing the thickness of the two sides of the cotton net, and making the overall thickness of the cotton net uniform. Secondly, when the flapping plate 53 moves toward the cotton web, it will drive the connecting rod 2 56 to move, so that the sliding plate 571 is close to the cotton web. At this time, the sliding plate 571 will squeeze the gas in the fixed frame 57, and the squeezed gas will be blocked by the spring blocking plate 572, thereby increasing the pressure of the gas. As the spring blocking plate 572 continues to move, the pushing plate 573 will contact the spring blocking plate 572, pushing the spring blocking plate 572 down, allowing the spring blocking plate 572 to accumulate rebound force. The spring blocking plate 572 descends, which will allow the jet plate 58 to be connected to the inside of the fixed frame 57, and the high-pressure gas will be ejected from the jet plate 58 toward the surface of the pressure roller 14, so that the fibers attached to the surface of the pressure roller 14 will fall off, avoiding the pressure roller 14 rubbing the cotton web, resulting in an increase in the friction between the two, and the fibers may adhere to the pressure roller 14, effectively preventing too much fiber from adhering to the pressure roller 14, resulting in uneven thickness at the outer wall of the pressure roller 14, affecting the compaction effect.
