Description

Technical Field

[0001] This invention relates to the field of nonwoven fabric hot pressing technology, specifically a nonwoven fabric production equipment with multiple pressing functions. Background Technology

[0002] Hot pressing can fuse nonwoven fabrics with different structures into a whole, giving them various properties such as water resistance, abrasion resistance, and barrier properties. These properties can even be combined. However, in existing production equipment, if the machine stops midway during the manufacturing process, the raw material rollers, which are in the unwinding state, cannot stop immediately but continue to roll. This causes the nonwoven fabric to become loose, and it needs to be adjusted to a tensioned state before restarting. Otherwise, the nonwoven fabric will have overlapping wrinkles, affecting the quality of hot pressing. Since the different layers of nonwoven fabric are not strictly aligned before hot pressing, cutting equipment is often needed to trim the edges of the composite nonwoven fabric after hot pressing to remove the uneven edges, resulting in waste of nonwoven fabric and a reduced yield. Existing winding rollers are in a fixed position. As the winding length increases, the winding diameter increases, and the newly hot-pressed nonwoven fabric will be subjected to oblique stretching, causing differences in stress between different pressing layers. This can cause the pressed nonwoven fabric to crack again in the middle, affecting the quality of the finished product. Summary of the Invention

[0003] The purpose of this invention is to provide a nonwoven fabric production equipment with multiple pressing functions to solve the problems raised in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a nonwoven fabric production equipment with multiple pressing functions, comprising an equipment mounting plate, at least two sets of feeding components, a number of correction components equal to the number of feeding components, a hot press, a base, a pair of receiving components, and receiving rollers. The equipment mounting plate and the base are disposed on both sides of the hot press. At least two sets of the feeding components and the correction components are all mounted on the equipment mounting plate. The correction components are located on the side of the equipment mounting plate closer to the hot press. The pair of receiving components are symmetrically mounted on both sides of the base. Each set of receiving components includes a conical top. The receiving rollers are disposed between the pair of conical tops. The operator places the nonwoven fabric raw material on the sleeve of each feeding component, then passes the nonwoven fabric through the two drum-shaped sleeve rollers of the corresponding correction component, presses the nonwoven fabric into the hot press, and finally fixes the end of the nonwoven fabric to the receiving rollers. The production equipment is then turned on to perform hot pressing on the nonwoven fabric.

[0005] Furthermore, each feeding assembly includes a pump base, crankshaft, plunger, impeller, oil tank, and pump pipe. The pump base is integrally formed by a low side block and a high side block in an L-shape. A sealing cavity is provided on the low side block, and the high side block is hollow. The sealing cavity is connected to the hollow part of the high side block, and a one-way valve is provided at the connection. The plunger is slidably installed in the sealing cavity. As the take-up roller rotates, the non-woven fabric raw material is continuously pulled into the hot press. At the same time, the non-woven fabric raw material drives the sleeve to rotate. The sleeve drives the slide shaft to rotate through the protrusion. The slide shaft drives the crankshaft to rotate. During the rotation, the crankshaft drives the plunger to move up and down in the sealing cavity.

[0006] Furthermore, a groove is formed on the top of the plunger, one end of the crankshaft passes through the equipment mounting plate, and the other end of the crankshaft passes through the high side block. The middle part of the crankshaft slides in contact with the groove of the plunger. An impeller is installed at the hollow position of the crankshaft in the high side block. The oil tank is installed at the bottom of the high side block, and an oil leakage groove is formed at the bottom of the oil tank corresponding to the position of the impeller. Holes are formed below the low side block and above the oil tank. The pump pipe is connected between the two holes, and a one-way valve is installed inside the pump pipe. The hollow part of the high side block is filled with hydraulic oil. When the plunger moves upward, the hydraulic oil is drawn into the sealed cavity. When the plunger moves downward... During the downward movement, hydraulic oil is pumped into the oil tank through the pump pipe. Two one-way valves prevent the hydraulic oil from flowing back. The hydraulic oil pumped into the oil tank leaks downward from the oil drain groove. Because the oil tank is located at a high position, the hydraulic oil gains a large gravitational potential energy when it leaks downward. The hydraulic oil impacts the impeller, causing the crankshaft to experience reverse resistance when rotating. That is, the rotation speed of the sleeve is suppressed when unwinding, and it only rotates when the nonwoven fabric is being dragged. When the equipment stops in the middle, the raw material roll on the sleeve will not continue to rotate due to rotational inertia, but will keep the nonwoven fabric in a taut state to prevent the nonwoven fabric from becoming loose when unwinding.

[0007] Furthermore, each of the feeding components also includes a chute shaft and a sleeve. The chute shaft is installed at one end of the crankshaft through the equipment mounting plate. The inner wall of the sleeve is provided with a protrusion. The sleeve is slidably installed on the chute shaft, and the protrusion cooperates with the groove on the chute shaft.

[0008] Furthermore, each set of the correction components includes a first motor, a gear, and a pair of sliders. The first motor is mounted on the equipment mounting plate, and the pair of sliders are slidably mounted in the equipment mounting plate. The two sides of the pair of sliders are provided with toothed grooves. The gear is mounted on the motor shaft of the first motor, and the two sides of the gear mesh with the toothed grooves on the pair of sliders. The first motor drives the gear to rotate, and the gear drives the pair of sliders to make fine adjustments. The pair of sliders move towards each other, and the sliders drive the optical axis to move. The optical axis moves synchronously with the drum-shaped roller. After the drum-shaped roller contacts the nonwoven fabric material, it stops moving. The nonwoven fabric is dragged and simultaneously drives the drum-shaped roller to rotate. Since the middle of the drum-shaped roller is slightly convex compared to the two ends, the tension in the middle of the nonwoven fabric in contact with it is higher than the tension on both sides. The greater the tension, the greater the friction.

[0009] Furthermore, each set of the correction components also includes an optical axis and a drum-shaped roller. The optical axis is mounted on the side of the slider away from the first motor, and the drum-shaped roller is rotatably mounted on the optical axis. The diameter of the middle part of the drum-shaped roller is larger than the diameters at both ends. If the nonwoven fabric shifts towards one side of the drum-shaped roller when being dragged, the side with increased shift is further away from the central protrusion of the drum-shaped roller, resulting in a gradual decrease in tension. Conversely, the side with decreased shift is further away from the central protrusion of the drum-shaped roller, resulting in a gradual increase in tension. The friction on the side with decreased shift is higher than that on the side with increased shift. Friction prevents the nonwoven fabric from shifting further, causing the forces on both sides of the nonwoven fabric to become unbalanced. Under continuous pulling, the nonwoven fabric begins to move automatically towards the side with reduced force until the forces on both sides of the nonwoven fabric reach dynamic balance. Through the setting of the drum-shaped sleeve roller, the nonwoven fabric is corrected and guided. After being corrected by the drum-shaped sleeve roller, the several layers of nonwoven fabric are aligned vertically and fed into the hot press, realizing the alignment between different layers of nonwoven fabric. This effectively increases the overlapping area of ​​the nonwoven fabric after hot pressing, reduces the cutting on both sides, saves nonwoven fabric raw materials, and improves the production efficiency of nonwoven fabric hot pressing.

[0010] Furthermore, each of the receiving components includes an annular frame, which is slidably connected to the base. The outer contour of the annular frame is provided with toothed grooves. A servo motor is installed inside the base corresponding to the bottom of each annular frame. A drive wheel is installed on the servo motor, and the drive wheel meshes with the toothed grooves of the annular frame.

[0011] Furthermore, each of the receiving components includes a screw, a sliding shaft, and a housing. The screw and sliding shaft are installed in an annular frame, and the screw and sliding shaft pass through the housing. The housing is slidably connected to the sliding shaft.

[0012] Furthermore, each of the receiving components includes a second motor, a linkage shaft, a worm gear, and a worm wheel. The second motor, worm gear, and worm wheel are all installed inside the housing. The linkage shaft is connected to the second motor, with one end of the linkage shaft passing through the housing. The worm gear is located outside the linkage shaft. The worm wheel is rotatably installed in the housing and meshes with the worm gear. A threaded groove is formed in the middle of the worm wheel, which engages with the screw. The second motor drives the splined shaft to rotate via the linkage shaft. The splined shaft drives the conical top to rotate. The two conical tops clamp and rotate the receiving roller. The electric push rod controls the splined shaft to push out. The length control cone tip clamps the take-up roller to a certain degree, or the take-up roller is completely retracted from the spline shaft and removed. As the linkage shaft rotates, the worm gear rotates synchronously. The worm gear drives the worm wheel to rotate, and the rotation of the worm wheel causes the entire machine to move through the screw drive, causing the height of the take-up roller to rise slowly. As the diameter of the nonwoven fabric being rolled up increases, the height of the take-up roller also increases. The nonwoven fabric pressed out of the hot press always moves in a straight line, giving the pressed nonwoven fabric sufficient cooling time, avoiding uneven tension on the upper and lower layers of the freshly pressed nonwoven fabric, which could cause separation, and improving the hot pressing quality of the nonwoven fabric.

[0013] Furthermore, each of the aforementioned take-up components also includes an electric push rod and a splined shaft. The electric push rod is installed inside the linkage shaft on the side away from the second motor. The splined shaft is connected to the piston rod of the electric push rod. The conical top is connected to the side of the splined shaft away from the electric push rod. The linkage shaft has an internal spline groove at the end near the splined shaft. The linkage shaft is slidably connected to the splined shaft through the internal spline groove. After each winding is completed, the operator removes the wound take-up roller, replaces it with a replacement take-up roller, and controls the servo motor to drive the drive wheel to rotate. The drive wheel drives the annular frame to rotate half a turn, and the machine box that has been raised to the top moves back down. The annular frame is rotated once after each winding is completed to facilitate the next winding operation.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The rotation of the unwinding roll drives the plunger to send the hydraulic oil pump to a high position. When the hydraulic oil leaks downward, it gains greater gravitational potential energy and impacts the impeller, causing the crankshaft to experience reverse resistance when rotating. This suppresses the rotational speed of the sleeve during unwinding. When the equipment stops midway, the raw material roll on the sleeve will not continue to rotate due to rotational inertia, but will keep the nonwoven fabric in a taut state, preventing the nonwoven fabric from becoming loose during unwinding.

[0016] 2. By setting up the drum-shaped sleeve roller, the non-woven fabric is corrected and guided. After being corrected by the drum-shaped sleeve roller, the multiple layers of non-woven fabric are aligned and fed into the hot press, realizing the alignment between different layers of non-woven fabric. This effectively increases the overlapping area of ​​the non-woven fabric after hot pressing, reduces the cutting on both sides, saves non-woven fabric raw materials, and improves the production efficiency of non-woven fabric hot pressing.

[0017] 3. By using a height-adjustable take-up roller, the nonwoven fabric pressed from the hot press always moves in a straight line, giving the pressed nonwoven fabric sufficient cooling time, avoiding uneven tension between the upper and lower layers of the freshly pressed nonwoven fabric, thus improving the hot pressing quality of the nonwoven fabric.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example: Figures 1-8 As shown, the present invention provides a technical solution: a nonwoven fabric production equipment with multiple pressing functions, including an equipment mounting plate 1, three sets of feeding components 2, a number of correction components 3 equal to the number of feeding components 2, a hot press 4, a base 5, a pair of receiving components 6, and receiving rollers 7. The equipment mounting plate 1 and the base 5 are located on both sides of the hot press 4. The three sets of feeding components 2 and the correction components 3 are all mounted on the equipment mounting plate 1. The correction components 3 are located on the side of the equipment mounting plate 1 closest to the hot press 4. The pair of receiving components 6 are symmetrically mounted on both sides of the base 5. Each set of receiving components 6 includes a conical top 30. The receiving rollers 7 are located between the pair of conical tops 30. The operator places the nonwoven fabric raw material on the sleeve 11 of each feeding component 2, then passes the nonwoven fabric through the two drum-shaped sleeve rollers 20 of the corresponding correction component 3, presses the nonwoven fabric into the hot press 4, and finally fixes the end of the nonwoven fabric to the receiving rollers 7. The production equipment is then turned on to perform hot pressing on the nonwoven fabric.

[0029] Each feeding assembly 2 includes a pump base 8, a crankshaft 9, a plunger 12, an impeller 13, an oil tank 14, and a pump pipe 15. The pump base 8 is integrally formed by a low side block and a high side block in an L-shape. A sealing cavity is formed on the low side block, and the high side block is hollow. The sealing cavity is connected to the hollow part of the high side block, and a one-way valve is provided at the connection. The plunger 12 is slidably installed in the sealing cavity, and a groove is formed on the top of the plunger 12. One end of the crankshaft 9 passes through the equipment mounting plate 1, and the other end of the crankshaft 9 passes through the high side block. The middle part of the crankshaft 9 is in sliding contact with the groove of the plunger 12. The crankshaft 9 is located on the high side block. An impeller 13 is installed in the hollow position, and an oil tank 14 is installed at the bottom of the high side block. An oil leakage groove is opened at the bottom of the oil tank 14 corresponding to the position of the impeller 13. Holes are opened below the low side block and above the oil tank 14. A pump pipe 15 is connected between the two holes. A one-way valve is installed inside the pump pipe 15. Each feeding assembly 2 also includes a chute shaft 10 and a sleeve 11. The chute shaft 10 is installed at one end of the crankshaft 9 that passes through the equipment mounting plate 1. The inner wall of the sleeve 11 is provided with a protrusion. The sleeve 11 is slidably installed on the chute shaft 10. The protrusion cooperates with the groove on the chute shaft 10.

[0030] As the receiving roller 7 rotates, the nonwoven fabric raw material is continuously pulled into the hot press 4. Simultaneously, the nonwoven fabric raw material drives the sleeve 11 to rotate. The sleeve 11 drives the sliding shaft 10 to rotate via a protrusion. The sliding shaft 10 drives the crankshaft 9 to rotate. During rotation, the crankshaft 9 drives the plunger 12 to move up and down in the sealed cavity. The hollow part of the high-side block is filled with hydraulic oil. When the plunger 12 moves upward, the hydraulic oil is drawn into the sealed cavity. When the plunger 12 moves downward, the hydraulic oil is pumped to the oil tank 14 through the pump pipe 15. Two one-way valves prevent the hydraulic oil from flowing backward. Due to the flow, the hydraulic oil pumped into the oil tank 14 leaks downwards from the oil drain groove. Because the oil tank 14 is located at a high position, the hydraulic oil gains a large gravitational potential energy when it leaks downwards. The hydraulic oil impacts the impeller 13, causing the crankshaft 9 to be subjected to reverse resistance when rotating. That is, the rotation speed of the sleeve 11 is suppressed when unwinding, and it only rotates when the nonwoven fabric is dragged. When the equipment stops in the middle, the raw material roll on the sleeve 11 will not continue to rotate due to the rotational inertia, but will keep the nonwoven fabric in a taut state to prevent the nonwoven fabric from becoming loose when unwinding.

[0031] Each set of calibration components 3 includes a first motor 16, a gear 17, and a pair of sliders 18. The first motor 16 is mounted on the equipment mounting plate 1, and the pair of sliders 18 are slidably mounted in the equipment mounting plate 1. The sides of the pair of sliders 18 that are close to each other have toothed grooves. The gear 17 is mounted on the motor shaft of the first motor 16, and the two sides of the gear 17 mesh with the toothed grooves on the pair of sliders 18 respectively. Each set of calibration components 3 also includes an optical shaft 19 and a drum-shaped roller 20. The optical shaft 19 is mounted on the side of the sliders 18 away from the first motor 16, and the drum-shaped roller 20 is rotatably mounted on the optical shaft 19. The diameter of the middle part of the drum-shaped roller 20 is larger than the diameter of both ends.

[0032] The first motor 16 drives the gear 17 to rotate, and the gear 17 drives a pair of sliders 18 to make fine adjustments. The pair of sliders 18 move towards each other, and the sliders 18 drive the optical shaft 19 to move. The optical shaft 19 moves synchronously with the drum-shaped roller 20. After the drum-shaped roller 20 comes into contact with the nonwoven fabric material, it stops moving. The nonwoven fabric is dragged and at the same time, it drives the drum-shaped roller 20 to rotate. Since the middle of the drum-shaped roller 20 is slightly convex compared to the two ends, the tension of the nonwoven fabric in the middle is higher than that on both sides. The greater the tension, the greater the friction. If the nonwoven fabric is dragged and shifts to one side of the drum-shaped roller 20, the distance from the convex part in the middle of the drum-shaped roller 20 increases, causing the tension to gradually decrease. The reduced distance from the middle protrusion of the drum-shaped roller 20 on the reduced side causes the tension to gradually increase. The friction on the reduced side is higher than that on the increased side, which prevents the nonwoven fabric from shifting further. The forces on both sides of the nonwoven fabric become unbalanced, and the nonwoven fabric begins to move automatically towards the reduced side under continuous pulling until the forces on both sides of the nonwoven fabric reach dynamic balance. The drum-shaped roller 20 is used to guide and correct the nonwoven fabric. After being corrected by the drum-shaped roller 20, the several layers of nonwoven fabric are aligned vertically and fed into the hot press 4, realizing the alignment between different layers of nonwoven fabric. This effectively increases the overlapping area of ​​the nonwoven fabric after hot pressing, reduces the cutting on both sides, saves nonwoven fabric raw materials, and improves the production efficiency of nonwoven fabric hot pressing.

[0033] Each set of receiving components 6 includes an annular frame 21, which is slidably connected to the base 5. The annular frame 21 has toothed grooves on its outer contour. A servo motor (not shown in the figure) is installed inside the base 5 corresponding to the area below each annular frame 21. A drive wheel is mounted on the servo motor, and the drive wheel meshes with the toothed grooves of the annular frame 21. Each set of receiving components 6 includes a screw 22, a sliding shaft 23, and a housing 24. The screw 22 and sliding shaft 23 are installed in the annular frame 21 and pass through the housing 24, which is slidably connected to the sliding shaft 23. Each set of receiving components 6 includes a second motor 25, a linkage shaft 26, a worm gear 27, and a worm wheel 28. The second motor 25, worm gear 27, and worm wheel 28 are all installed in the housing 24. Inside the 4th assembly, the linkage shaft 26 is connected to the second motor 25. One end of the linkage shaft 26 passes through the housing 24. The worm gear 27 is located on the outside of the linkage shaft 26. The worm wheel 28 is rotatably installed in the housing 24 and meshes with the worm gear 27. A threaded groove is provided in the middle of the worm wheel 28, which cooperates with the screw 22. Each set of receiving components 6 also includes an electric push rod 29 and a splined shaft 31. The electric push rod 29 is installed inside the linkage shaft 26 on the side away from the second motor 25. The splined shaft 31 is connected to the piston rod of the electric push rod 29. The conical top 30 is connected to the side of the splined shaft 31 away from the electric push rod 29. An internal splined groove is provided inside the linkage shaft 26 near the splined shaft 31. The linkage shaft 26 is slidably connected to the splined shaft 31 through the internal splined groove.

[0034] The second motor 25 drives the splined shaft 31 to rotate via the linkage shaft 26. The splined shaft 31 drives the conical tops 30 to rotate. The two conical tops 30 clamp the take-up roller 7 and rotate it. The electric push rod 29 controls the extension length of the splined shaft 31 to control the clamping degree of the conical tops 30 on the take-up roller 7, or completely retracts the splined shaft 31 to remove the take-up roller 7. At the same time as the linkage shaft 26 rotates, the worm gear 27 rotates synchronously. The worm gear 27 drives the worm wheel 28 to rotate. The rotation of the worm wheel 28 causes the entire machine box 24 to move through the screw drive, so that the height of the take-up roller 7 is slowly raised. As the diameter of the wound nonwoven fabric increases, the take-up roller 7... The height of the material roller 7 also increases accordingly, and the nonwoven fabric pressed out of the hot press 4 always moves in a straight line, giving the pressed nonwoven fabric enough cooling time, avoiding uneven tension on the upper and lower layers of the newly pressed nonwoven fabric and separation, thus improving the hot pressing quality of the nonwoven fabric. After each winding is completed, the operator removes the wound material roller 7, replaces it with a replacement material roller 7, controls the servo motor to drive the drive wheel to rotate, and the drive wheel drives the ring frame 21 to rotate half a turn. The machine box 24, which has been raised to the top, moves down again. The ring frame 21 is rotated once after each winding is completed to facilitate the next winding operation.

[0035] The working principle of this invention is as follows: The operator places the nonwoven fabric raw material on the sleeve 11 of each feeding component 2, then passes the nonwoven fabric through the two drum-shaped sleeve rollers 20 of the corresponding correction component 3, presses the nonwoven fabric into the hot press 4, and finally fixes the end of the nonwoven fabric on the take-up roller 7, and starts the production equipment to hot press the nonwoven fabric.

[0036] As the receiving roller 7 rotates, the nonwoven fabric raw material is continuously pulled into the hot press 4. Simultaneously, the nonwoven fabric raw material drives the sleeve 11 to rotate. The sleeve 11 drives the sliding shaft 10 to rotate via a protrusion. The sliding shaft 10 drives the crankshaft 9 to rotate. During rotation, the crankshaft 9 drives the plunger 12 to move up and down in the sealed cavity. The hollow part of the high-side block is filled with hydraulic oil. When the plunger 12 moves upward, the hydraulic oil is drawn into the sealed cavity. When the plunger 12 moves downward, the hydraulic oil is pumped to the oil tank 14 through the pump pipe 15. Two one-way valves prevent the hydraulic oil from flowing backward. Due to the flow, the hydraulic oil pumped into the oil tank 14 leaks downwards from the oil drain groove. Because the oil tank 14 is located at a high position, the hydraulic oil gains a large gravitational potential energy when it leaks downwards. The hydraulic oil impacts the impeller 13, causing the crankshaft 9 to be subjected to reverse resistance when rotating. That is, the rotation speed of the sleeve 11 is suppressed when unwinding, and it only rotates when the nonwoven fabric is dragged. When the equipment stops in the middle, the raw material roll on the sleeve 11 will not continue to rotate due to the rotational inertia, but will keep the nonwoven fabric in a taut state to prevent the nonwoven fabric from becoming loose when unwinding.

[0037] The first motor 16 drives the gear 17 to rotate, and the gear 17 drives a pair of sliders 18 to make fine adjustments. The pair of sliders 18 move towards each other, and the sliders 18 drive the optical shaft 19 to move. The optical shaft 19 moves synchronously with the drum-shaped roller 20. After the drum-shaped roller 20 comes into contact with the nonwoven fabric material, it stops moving. The nonwoven fabric is dragged and at the same time, it drives the drum-shaped roller 20 to rotate. Since the middle of the drum-shaped roller 20 is slightly convex compared to the two ends, the tension of the nonwoven fabric in the middle is higher than that on both sides. The greater the tension, the greater the friction. If the nonwoven fabric is dragged and shifts to one side of the drum-shaped roller 20, the distance from the convex part in the middle of the drum-shaped roller 20 increases, causing the tension to gradually decrease. The reduced distance from the middle protrusion of the drum-shaped roller 20 on the reduced side causes the tension to gradually increase. The friction on the reduced side is higher than that on the increased side, which prevents the nonwoven fabric from shifting further. The forces on both sides of the nonwoven fabric become unbalanced, and the nonwoven fabric begins to move automatically towards the reduced side under continuous pulling until the forces on both sides of the nonwoven fabric reach dynamic balance. The drum-shaped roller 20 is used to guide and correct the nonwoven fabric. After being corrected by the drum-shaped roller 20, the several layers of nonwoven fabric are aligned vertically and fed into the hot press 4, realizing the alignment between different layers of nonwoven fabric. This effectively increases the overlapping area of ​​the nonwoven fabric after hot pressing, reduces the cutting on both sides, saves nonwoven fabric raw materials, and improves the production efficiency of nonwoven fabric hot pressing.

[0038] The second motor 25 drives the splined shaft 31 to rotate via the linkage shaft 26. The splined shaft 31 drives the conical tops 30 to rotate. The two conical tops 30 clamp the take-up roller 7 and rotate it. The electric push rod 29 controls the extension length of the splined shaft 31 to control the clamping degree of the conical tops 30 on the take-up roller 7, or completely retracts the splined shaft 31 to remove the take-up roller 7. At the same time as the linkage shaft 26 rotates, the worm gear 27 rotates synchronously. The worm gear 27 drives the worm wheel 28 to rotate. The rotation of the worm wheel 28 causes the entire machine box 24 to move through the screw drive, so that the height of the take-up roller 7 is slowly raised. As the diameter of the wound nonwoven fabric increases, the take-up roller 7... The height of the material roller 7 also increases accordingly, and the nonwoven fabric pressed out of the hot press 4 always moves in a straight line, giving the pressed nonwoven fabric enough cooling time, avoiding uneven tension on the upper and lower layers of the newly pressed nonwoven fabric and separation, thus improving the hot pressing quality of the nonwoven fabric. After each winding is completed, the operator removes the wound material roller 7, replaces it with a replacement material roller 7, controls the servo motor to drive the drive wheel to rotate, and the drive wheel drives the ring frame 21 to rotate half a turn. The machine box 24, which has been raised to the top, moves down again. The ring frame 21 is rotated once after each winding is completed to facilitate the next winding operation.
