Description

Technical Field

[0001] The invention relates to the technical field of non-woven fabric hot pressing, in particular to non-woven fabric production equipment with multiple pressing functions. Background Art

[0002] By means of hot pressing, non-woven fabrics with different tissue characteristics can be pressed into a whole, so that the non-woven fabrics have different characteristics such as waterproofness, wear resistance, barrier properties, etc., and these characteristics can even be used in combination. When the existing production equipment is manufacturing pressed non-woven fabrics, if the equipment is stopped halfway, the raw material roller cannot stop immediately in the unwinding state, but continues to roll, which causes the non-woven fabric to become loose. Before restarting, it needs to be adjusted to a tensioned state for normal use, otherwise the non-woven fabric will be wrinkled and complex, affecting the quality of hot pressing; because the non-woven fabrics of different layers are not strictly aligned before hot pressing, cutting equipment is often required after hot pressing to trim the composite non-woven fabric, cut off the uneven edges of hot pressing, resulting in waste of non-woven fabrics and reducing the yield rate; the existing winding roller is in a fixed position. As the length of winding increases, the winding diameter increases, and the non-woven fabric that has just been hot-pressed will be stretched obliquely, resulting in differences in the forces between different pressed layers, and the middle of the pressed non-woven fabric will be cracked again, affecting the quality of the finished non-woven fabric. Summary of the invention

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

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a non-woven fabric production equipment with multiple pressing functions, comprising an equipment mounting plate, at least two groups of feeding components, correction components with the same number as the feeding components, a hot press, a base, a pair of receiving components and a receiving roller, the equipment mounting plate and the base are arranged on both sides of the hot press, at least two groups of the feeding components and the correction components are installed on the equipment mounting plate, the correction components are located on the side of the equipment mounting plate close to the hot press, a pair of the receiving components are symmetrically installed on both sides of the base, each group of the receiving components includes a conical top, and the receiving roller is arranged between a pair of conical tops, the operator places the non-woven fabric raw material on the sleeve of each feeding component, and then passes the non-woven fabric through the two drum-shaped sleeve rollers of the corresponding correction component, presses the non-woven fabric into the hot press, and finally fixes the end of the non-woven fabric on the receiving roller, and turns on the production equipment to perform hot pressing on the non-woven fabric.

[0005] Furthermore, each group of the feeding components includes a pump seat body, a crankshaft, a plunger, an impeller, an oil tank and a pump pipe. The pump seat body is composed of a low side block and a high side block in an L-shape. A sealing cavity is opened 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. A one-way valve is provided at the connection point. The plunger is slidably installed in the sealing cavity. As the receiving 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, and the sleeve drives the slide shaft to rotate through the protrusion, and the slide shaft drives the crankshaft to rotate. During the rotation of the crankshaft, the plunger drives the plunger to move up and down in the sealing cavity.

[0006] Furthermore, a slide groove is provided 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 is in sliding contact with the slide groove of the plunger, an impeller is installed on the crankshaft at a hollow position in the high side block, the oil tank is installed at the bottom of the high side block, an oil leakage groove is provided at the bottom of the oil tank corresponding to the position of the impeller, holes are provided below the low side block and above the oil tank, the pump pipe is connected between the two holes, a one-way valve is provided inside the pump pipe, the hollow part of the high side block is filled with hydraulic oil, and when the plunger moves upward, the hydraulic oil is sucked into the sealed cavity, and when the plunger moves During downward movement, the hydraulic oil is pumped into the oil tank through the pump pipe. The two one-way valves prevent the hydraulic oil from flowing back. The hydraulic oil pumped into the oil tank leaks downward from the oil leakage groove. Due to the high position of the oil tank, the hydraulic oil obtains a large gravitational potential energy when leaking downward. The hydraulic oil impacts the impeller, causing the crankshaft to be subjected to reverse resistance when rotating, that is, the speed of the sleeve during unwinding is suppressed, and it only rotates when the non-woven fabric is dragged. When the equipment stops halfway, the raw material roll on the sleeve will not continue to rotate due to the influence of rotational inertia, but keep the non-woven fabric in a tensioned state to prevent the non-woven fabric from loosening during unwinding.

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

[0008] Furthermore, each group of the correction components includes a first motor, a gear, and a pair of sliders. The first motor is installed on the equipment mounting plate, and the pair of sliders are slidably installed in the equipment mounting plate. A tooth groove is opened on the side of the pair of sliders close to each other, and the gear is installed on the motor shaft of the first motor. The two sides of the gear are respectively engaged with the tooth grooves on the pair of sliders. The first motor drives the gear to rotate, and the gear drives the pair of sliders to perform fine adjustment. The pair of sliders move toward each other, and the slider drives the optical axis to move. The optical axis and the drum sleeve roller move synchronously. The drum sleeve roller stops moving after contacting the non-woven fabric raw material, and the non-woven fabric is dragged and drives the drum sleeve roller to rotate at the same time. Since the middle part of the drum sleeve roller is slightly raised compared to the two ends, the tension in the middle part of the non-woven fabric in contact with it is higher than the tension on both sides. The greater the tension, the greater the friction.

[0009] Furthermore, each group of the correction components also includes an optical axis and a drum-shaped roller, the optical axis is installed on the side of the slider away from the first motor, the drum-shaped roller is rotatably installed on the optical axis, the middle diameter of the drum-shaped roller is larger than the diameters at both ends, and if the non-woven fabric is deviated toward one side of the drum-shaped roller when being dragged, the distance from the side with increased deviation to the protrusion in the middle of the drum-shaped roller increases, resulting in a gradual decrease in tension, and the distance from the side with reduced deviation to the protrusion in the middle of the drum-shaped roller decreases, resulting in a gradual increase in tension, and the friction force on the reduced side is higher than the friction force on the increased side The friction force can prevent the non-woven fabric from continuing to deviate. The forces on both sides of the non-woven fabric lose balance. Under continuous traction, the non-woven fabric begins to automatically move to the reducing side until the forces on both sides of the non-woven fabric reach dynamic balance. The non-woven fabric is guided by the setting of the drum sleeve roller. After being corrected by the drum sleeve roller, the layers of non-woven fabric are aligned up and down and sent to the hot press machine to achieve mutual alignment between different layers of non-woven fabrics, effectively increase the overlapping area of ​​the non-woven fabric after hot pressing, reduce the cutting on both sides, save non-woven fabric raw materials, and improve the production efficiency of hot pressing of non-woven fabrics.

[0010] Furthermore, each group of the material receiving components includes an annular frame, which is slidably connected to the base, and a tooth groove is provided on the outer contour of the annular frame. A servo motor is installed under each annular frame inside the base, and a driving wheel is installed on the servo motor, and the driving wheel is engaged with the tooth groove of the annular frame.

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

[0012] Furthermore, each group of the material receiving components includes a second motor, a linkage shaft, a worm and a worm wheel. The second motor, worm and worm wheel are all installed in a chassis. The linkage shaft is connected to the second motor. One end of the linkage shaft passes through the chassis. The worm is arranged on the outside of the linkage shaft. The worm wheel is rotatably installed in the chassis. The worm wheel is meshed with the worm. A thread groove is provided in the middle of the worm wheel. The thread groove cooperates with the screw. The second motor drives the spline shaft to rotate through the linkage shaft. The spline shaft drives the conical top to rotate. The two conical tops clamp the material receiving roller and rotate. The electric push rod controls the spline shaft to push out The length controls the degree of clamping of the conical top on the receiving roller, or the spline shaft is completely retracted to remove the receiving roller. When the linkage shaft rotates, the worm rotates synchronously, and the worm drives the worm wheel to rotate. The rotation of the worm wheel moves the entire chassis through the spiral transmission, so that the height of the receiving roller is slowly raised. As the diameter of the rolled pressed non-woven fabric increases, the height of the receiving roller also increases. The non-woven fabric pressed out of the hot press always keeps moving straight, giving the pressed non-woven fabric enough cooling time, avoiding the upper and lower layers of the newly pressed non-woven fabric from being separated due to uneven tension, and improving the hot pressing quality of the non-woven fabric.

[0013] Furthermore, each group of the material receiving components also includes an electric push rod and a spline shaft, the electric push rod is installed on the side of the linkage shaft away from the second motor, the spline shaft is connected to the piston rod of the electric push rod, the conical top is connected to the side of the spline shaft away from the electric push rod, and the linkage shaft is provided with an internal spline groove near one end of the spline shaft, and the linkage shaft is slidingly connected to the spline shaft through the internal spline groove. After each winding is completed, the operator removes the wound material receiving roller and replaces it with a replacement material receiving roller, controls the servo motor to drive the driving wheel to rotate, and the driving wheel drives the annular frame to reverse half a circle, and the chassis raised to the top is transferred to the bottom again, and the annular frame is reversed once after each winding is completed to facilitate the next winding operation.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The rotation of the unwinding roll drives the plunger to pump the hydraulic oil to a high place. When the hydraulic oil leaks downward, it obtains a large gravitational potential energy and impacts the impeller, so that the crankshaft is subjected to reverse resistance when rotating, that is, the rotation speed of the sleeve during unwinding is suppressed. When the equipment stops halfway, the raw material roll on the sleeve will not continue to rotate due to the influence of rotational inertia, but keep the non-woven fabric in a tensioned state to prevent the non-woven fabric from loosening during unwinding.

[0015] 2. Through the setting of the drum-shaped sleeve roller, the non-woven fabric is guided and corrected. After being corrected by the drum-shaped sleeve roller, several layers of non-woven fabric are aligned up and down and sent to the hot press machine, so that different layers of non-woven fabrics are aligned with each other, effectively increasing the overlapping area of ​​the non-woven fabric after hot pressing, reducing the cutting on both sides, saving non-woven fabric raw materials, and improving the production efficiency of non-woven fabric hot pressing.

[0016] 3. By setting the receiving roller that can be raised in height, the non-woven fabric pressed out of the hot press always keeps moving straight, giving the pressed non-woven fabric enough cooling time, avoiding the upper and lower layers of the newly pressed non-woven fabric from being separated due to uneven tension, and improving the hot pressing quality of the non-woven fabric.

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] Example: Figure 1-Figure 8As shown, the present invention provides a technical solution, a non-woven fabric production equipment with multiple pressing functions, including an equipment installation plate 1, three groups of feeding components 2, correction components 3 with the same number as the feeding components 2, a hot press 4, a base 5, a pair of receiving components 6 and a receiving roller 7, the equipment installation plate 1 and the base 5 are arranged on both sides of the hot press 4, the three groups of feeding components 2 and the correction components 3 are all installed on the equipment installation plate 1, the correction component 3 is located on the side of the equipment installation plate 1 close to the hot press 4, a pair of receiving components 6 are symmetrically installed on both sides of the base 5, each group of receiving components 6 includes a conical top 30, and the receiving roller 7 is arranged between the pair of conical tops 30, the operator places the non-woven fabric raw material on the sleeve 11 of each feeding component 2, and then passes the non-woven fabric through the two drum-shaped sleeve rollers 20 of the corresponding correction component 3, presses the non-woven fabric into the hot press 4, and finally fixes the end of the non-woven fabric on the receiving roller 7, and starts the production equipment to perform hot pressing on the non-woven fabric.

[0021] Each group of feeding components 2 includes a pump seat body 8, a crankshaft 9, a plunger 12, an impeller 13, an oil tank 14 and a pump pipe 15. The pump seat body 8 is composed of a low side block and a high side block in an L-shaped body. 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 12 is slidably installed in the sealing cavity, and a slide groove is provided 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 slide groove of the plunger 12, and the crankshaft 9 is located in the high side block. An impeller 13 is installed at the hollow position, an oil tank 14 is installed at the bottom of the high side block, an oil leakage groove is opened at the position of the impeller 13 at the bottom of the oil tank 14, 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 arranged inside the pump pipe 15, each group of feeding components 2 also includes a slide shaft 10 and a sleeve 11, the slide shaft 10 is installed at one end of the crankshaft 9 penetrating the equipment mounting plate 1, a protrusion is arranged on the inner wall of the sleeve 11, the sleeve 11 is slidably installed on the slide shaft 10, and the protrusion matches the groove on the slide shaft 10.

[0022] As the receiving roller 7 rotates, the non-woven fabric raw material is continuously pulled into the hot press 4. At the same time, the non-woven fabric raw material drives the sleeve 11 to rotate. The sleeve 11 drives the slide shaft 10 to rotate through the protrusion. The slide shaft 10 drives the crankshaft 9 to rotate. During the rotation of the crankshaft 9, the plunger 12 moves 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 sucked into the sealed cavity. When the plunger 12 moves downward, the hydraulic oil is pumped into the oil tank 14 through the pump pipe 15. The two one-way valves prevent the hydraulic oil from flowing back. Due to the effect of flow, the hydraulic oil pumped into the oil tank 14 leaks downward from the oil leakage groove. Since the oil tank 14 is located at a higher position, the hydraulic oil obtains a large gravitational potential energy when leaking downward. The hydraulic oil impacts the impeller 13, so that the crankshaft 9 is subjected to reverse resistance when rotating, that is, the rotation speed of the sleeve 11 during unwinding is suppressed, and it only rotates when the non-woven fabric is dragged. When the equipment stops halfway, the raw material roll on the sleeve 11 will not continue to rotate due to the influence of rotational inertia, but keeps the non-woven fabric in a tensioned state to prevent the non-woven fabric from loosening during unwinding.

[0023] Each set of correction components 3 includes a first motor 16, a gear 17, and a pair of sliders 18. The first motor 16 is installed on the equipment mounting plate 1. The pair of sliders 18 are slidably installed in the equipment mounting plate 1. A tooth groove is provided on the side of the pair of sliders 18 close to each other. The gear 17 is installed on the motor shaft of the first motor 16. The two sides of the gear 17 are respectively meshed with the tooth grooves on the pair of sliders 18. Each set of correction components 3 also includes an optical axis 19 and a drum roller 20. The optical axis 19 is installed on the side of the slider 18 away from the first motor 16. The drum roller 20 is rotatably installed on the optical axis 19. The middle diameter of the drum roller 20 is larger than the diameter at both ends.

[0024] 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 toward each other, and the slider 18 drives the optical axis 19 to move. The optical axis 19 moves synchronously with the drum roller 20. The drum roller 20 stops moving after contacting the non-woven fabric raw material, and the non-woven fabric is dragged and drives the drum roller 20 to rotate at the same time. Since the middle part of the drum roller 20 is slightly raised compared with the two ends, the tension in the middle part of the non-woven fabric in contact with it is higher than the tension on both sides. The greater the tension, the greater the friction. If the non-woven fabric is deviated toward one side of the drum roller 20 when being dragged, the distance between the side with increased deviation and the protrusion in the middle part of the drum roller 20 increases, resulting in a gradual decrease in tension and a deviation. The distance between the reduced side and the raised part in the middle of the drum roller 20 is reduced, resulting in a gradual increase in tension. The friction force on the reduced side is higher than that on the increased side, which prevents the non-woven fabric from continuing to deviate. The forces on both sides of the non-woven fabric lose balance, and the non-woven fabric begins to automatically move toward the reduced side under continuous traction until the forces on both sides of the non-woven fabric reach dynamic balance. The non-woven fabric is corrected and guided by the setting of the drum roller 20. After being corrected by the drum roller 20, several layers of non-woven fabric are aligned up and down and sent to the hot press 4, so that different layers of non-woven fabric are aligned with each other, effectively increasing the overlapping area of ​​the non-woven fabric after hot pressing, reducing the cutting on both sides, saving non-woven fabric raw materials, and improving the hot pressing production efficiency of non-woven fabric.

[0025] Each group of receiving components 6 includes an annular frame 21, which is slidably connected to the base 5. A tooth groove is provided on the outer contour of the annular frame 21. A servo motor (not shown in the figure) is installed inside the base 5 corresponding to the bottom of each annular frame 21. A driving wheel is installed on the servo motor, and the driving wheel is meshed with the tooth groove of the annular frame 21. Each group of receiving components 6 includes a screw 22, a sliding shaft 23 and a chassis 24. The screw 22 and the sliding shaft 23 are installed in the annular frame 21. The screw 22 and the sliding shaft 23 pass through the chassis 24, and the chassis 24 is slidably connected to the sliding shaft 23. Each group of receiving components 6 includes a second motor 25, a linkage shaft 26, a worm 27 and a worm wheel 28. The second motor 25, the worm 27 and the worm wheel 28 are all installed in the chassis 2 4, the linkage shaft 26 is connected to the second motor 25, one end of the linkage shaft 26 passes through the chassis 24, the worm 27 is arranged on the outside of the linkage shaft 26, the worm wheel 28 is rotatably installed in the chassis 24, the worm wheel 28 is meshed with the worm 27, the middle part of the worm wheel 28 is provided with a thread groove, and the thread groove cooperates with the screw 22. Each group of receiving components 6 also includes an electric push rod 29 and a spline shaft 31. The electric push rod 29 is installed on the side of the linkage shaft 26 away from the second motor 25, the spline shaft 31 is connected to the piston rod of the electric push rod 29, and the conical top 30 is connected to the side of the spline shaft 31 away from the electric push rod 29. An inner spline groove is arranged inside the linkage shaft 26 near one end of the spline shaft 31, and the linkage shaft 26 is slidably connected with the spline shaft 31 through the inner spline groove.

[0026] The second motor 25 drives the spline shaft 31 to rotate through the linkage shaft 26, and the spline shaft 31 drives the conical top 30 to rotate. The two conical tops 30 clamp the receiving roller 7 and rotate. The electric push rod 29 controls the length of the spline shaft 31 to control the clamping degree of the conical top 30 on the receiving roller 7, or completely retracts the spline shaft 31 to remove the receiving roller 7. When the linkage shaft 26 rotates, the worm 27 rotates synchronously therewith, and the worm 27 drives the worm wheel 28 to rotate. The rotation of the worm wheel 28 moves the entire chassis 24 through the spiral transmission, so that the height of the receiving roller 7 is slowly raised. As the diameter of the rolled pressed non-woven fabric increases, the receiving roller 7 is retracted. The height of the material roller 7 also increases accordingly, and the non-woven fabric pressed out of the hot press 4 always keeps moving straight, giving the pressed non-woven fabric enough cooling time to avoid the upper and lower layers of the newly pressed non-woven fabric from being separated due to uneven tension, thereby improving the hot pressing quality of the non-woven fabric. After each winding is completed, the operator removes the wound material roller 7, replaces the replaced material roller 7, controls the servo motor to drive the driving wheel to rotate, and the driving wheel drives the annular frame 21 to reverse half a circle, and the chassis 24 raised to the top is transferred to the bottom again. After each winding is completed, the annular frame 21 is reversed once to facilitate the next winding operation.

[0027] The working principle of the present invention is as follows: the operator places the non-woven fabric raw material on the sleeve 11 of each feeding component 2, then passes the non-woven fabric through the two drum-shaped sleeve rollers 20 of the corresponding correction component 3, presses the non-woven fabric into the hot press 4, and finally fixes the end of the non-woven fabric on the receiving roller 7, and starts the production equipment to perform hot pressing on the non-woven fabric.

[0028] As the receiving roller 7 rotates, the non-woven fabric raw material is continuously pulled into the hot press 4. At the same time, the non-woven fabric raw material drives the sleeve 11 to rotate. The sleeve 11 drives the slide shaft 10 to rotate through the protrusion. The slide shaft 10 drives the crankshaft 9 to rotate. During the rotation of the crankshaft 9, the plunger 12 moves 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 sucked into the sealed cavity. When the plunger 12 moves downward, the hydraulic oil is pumped into the oil tank 14 through the pump pipe 15. The two one-way valves prevent the hydraulic oil from flowing back. Due to the effect of flow, the hydraulic oil pumped into the oil tank 14 leaks downward from the oil leakage groove. Since the oil tank 14 is located at a higher position, the hydraulic oil obtains a large gravitational potential energy when leaking downward. The hydraulic oil impacts the impeller 13, so that the crankshaft 9 is subjected to reverse resistance when rotating, that is, the rotation speed of the sleeve 11 during unwinding is suppressed, and it only rotates when the non-woven fabric is dragged. When the equipment stops halfway, the raw material roll on the sleeve 11 will not continue to rotate due to the influence of rotational inertia, but keeps the non-woven fabric in a tensioned state to prevent the non-woven fabric from loosening during unwinding.

[0029] 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 toward each other, and the slider 18 drives the optical axis 19 to move. The optical axis 19 moves synchronously with the drum roller 20. The drum roller 20 stops moving after contacting the non-woven fabric raw material, and the non-woven fabric is dragged and drives the drum roller 20 to rotate at the same time. Since the middle part of the drum roller 20 is slightly raised compared with the two ends, the tension in the middle part of the non-woven fabric in contact with it is higher than the tension on both sides. The greater the tension, the greater the friction. If the non-woven fabric is deviated toward one side of the drum roller 20 when being dragged, the distance between the side with increased deviation and the protrusion in the middle part of the drum roller 20 increases, resulting in a gradual decrease in tension and a deviation. The distance between the reduced side and the raised part in the middle of the drum roller 20 is reduced, resulting in a gradual increase in tension. The friction force on the reduced side is higher than that on the increased side, which prevents the non-woven fabric from continuing to deviate. The forces on both sides of the non-woven fabric lose balance, and the non-woven fabric begins to automatically move toward the reduced side under continuous traction until the forces on both sides of the non-woven fabric reach dynamic balance. The non-woven fabric is corrected and guided by the setting of the drum roller 20. After being corrected by the drum roller 20, several layers of non-woven fabric are aligned up and down and sent to the hot press 4, so that different layers of non-woven fabric are aligned with each other, effectively increasing the overlapping area of ​​the non-woven fabric after hot pressing, reducing the cutting on both sides, saving non-woven fabric raw materials, and improving the hot pressing production efficiency of non-woven fabric.

[0030] The second motor 25 drives the spline shaft 31 to rotate through the linkage shaft 26, and the spline shaft 31 drives the conical top 30 to rotate. The two conical tops 30 clamp the receiving roller 7 and rotate. The electric push rod 29 controls the length of the spline shaft 31 to control the clamping degree of the conical top 30 on the receiving roller 7, or completely retracts the spline shaft 31 to remove the receiving roller 7. When the linkage shaft 26 rotates, the worm 27 rotates synchronously therewith, and the worm 27 drives the worm wheel 28 to rotate. The rotation of the worm wheel 28 moves the entire chassis 24 through the spiral transmission, so that the height of the receiving roller 7 is slowly raised. As the diameter of the rolled pressed non-woven fabric increases, the receiving roller 7 is retracted. The height of the material roller 7 also increases accordingly, and the non-woven fabric pressed out of the hot press 4 always keeps moving straight, giving the pressed non-woven fabric enough cooling time to avoid the upper and lower layers of the newly pressed non-woven fabric from being separated due to uneven tension, thereby improving the hot pressing quality of the non-woven fabric. After each winding is completed, the operator removes the wound material roller 7, replaces the replaced material roller 7, controls the servo motor to drive the driving wheel to rotate, and the driving wheel drives the annular frame 21 to reverse half a circle, and the chassis 24 raised to the top is transferred to the bottom again. After each winding is completed, the annular frame 21 is reversed once to facilitate the next winding operation.
