AI Technical Summary
Existing napping machines tend to produce creases and wrinkles that are difficult to eliminate when processing lighter and thinner fabrics, especially when the tension is increased to prevent holes. Subsequent setting processes often fail to completely eliminate these wrinkles.
A high-efficiency napping machine for improving creases and wrinkles was designed. By setting multiple tension zones on the worktable, including a pre-tension zone, a high-tension zone, and a tension buffer zone, and equipping it with sensing and force application components, the tension of the fabric is dynamically adjusted. At the same time, an ironing component is used to smooth the fabric and reduce wrinkles.
It effectively prevents wrinkles from forming on the fabric when the tension changes too quickly, and by combining multiple tension zones and ironing components, it significantly improves the wrinkle problem and enhances the smoothness of the fabric.

Abstract
Description
Technical Field
[0001] This invention relates to the field of napping machine technology, specifically a napping machine that efficiently improves creases and wrinkles. Background Technology
[0002] A napping machine is a textile fabric processing equipment that uses dense steel needles to lift chemical fibers from the surface of textiles and comb the lifted fibers to form nap on the surface of the fabric.
[0003] Generally, brushed fabrics, especially lighter or thinner fabrics like jersey, will develop some creases after passing through the exit rollers of a brushing machine. This is because when brushing thinner knitted fabrics like jersey, the tension is set higher to prevent the fabric from tearing or breaking. This higher tension inevitably causes wrinkles to appear on the fabric surface upon exiting, and once these wrinkles form, they are difficult to remove in subsequent finishing processes. Summary of the Invention

[0008] Hollow elastic rubber blocks are symmetrically arranged on the left and right sides of the top of the base. The base has grooves that communicate with the elastic rubber blocks. A sensing component is located in the left elastic rubber block and a force application component is located in the right elastic rubber block. The fabric applies downward pressure to the left elastic rubber block, and the sensing component feeds back the information to the force application component. The force application component adjusts the distance between the right elastic rubber block and the fabric output roller.
[0009] Preferably, the sensing component includes a crossbar, an elastic sheet, a laser pointer, and a light-catching module. The crossbar abuts against the top of the inner wall of the left elastic rubber block. The elastic sheet is placed in the groove on the left side of the base, and the upper end of the elastic sheet is connected to the body of the crossbar. The light-catching module is located in the base. The laser pointer is connected to the body of the crossbar. The light emitted by the laser pointer is obliquely downward and illuminates the working end of the light-catching module.
[0010] Preferably, the force-applying component includes a second crossbar, an arc-shaped plate, a sliding rod, and a connecting cloth. The second crossbar abuts against the top of the inner wall of the right elastic rubber block. The arc-shaped plate is located in the groove on the right side of the base. The middle section of the arc-shaped plate is pivotally connected to the base. The upper end of the arc-shaped plate is connected to the body of the second crossbar. A cavity is provided in the base. The end of the sliding rod slides in the cavity. A screw is pivotally connected in the cavity. The screw thread passes through the sliding rod. The sliding rod and the arc-shaped plate are connected by the connecting cloth.
[0011] Preferably, the bottom of the workbench is connected to an electric actuator, the lower end of which is pivotally connected to the end of a roller. The roller body has a groove along its length for the fabric to pass through. An extension piece is connected to the end of the roller, and a spring is connected between the extension piece and the lower end of the electric actuator.
[0012] Preferably, a sliding cavity is provided in the lower end of the electric push rod, and a tension sensor is slidably fitted in the sliding cavity. A magnetic block is provided on the inner wall of the sliding cavity near the spring side, and a magnetic ring is connected to the side of the tension sensor away from the magnetic block. An extension plate is connected to a steel wire, which extends into the tension sensor and is connected to the tension sensor. There is a mutual repulsive force between the magnetic block and the magnetic ring.

[0015] (III) Beneficial Effects This invention provides a napping machine for efficiently improving creases and wrinkles. It has the following beneficial effects: 1. This efficient napping machine for improving creases and wrinkles has a traction roller, pressure roller, napping roller, base and fabric output roller set up in sequence on the worktable. The area between the traction roller and the pressure roller is a pre-tension zone, the area between the pressure roller and the roller forms a high-tension zone, and the area between the roller and the base forms a tension buffer zone. By setting up multiple tension zones, the fabric can gradually adapt to the tension changes, avoiding wrinkles caused by excessively rapid tension changes.
[0016] 2. This high-efficiency napping machine for improving creases and wrinkles features rubber elastic blocks on both sides of the base. A sensing component is located within the left rubber elastic block, and a force-applying component is located within the right rubber elastic block. The sensing component detects the tension of the fabric on the left side of the base and adjusts the pressure applied to the output roller by the force-applying component accordingly. When the pressure on the left side of the base is too high, the force-applying component reduces the pressure on the output roller, making it easier for the fabric to be pulled out from between the output roller and the base. This reduces the tension of subsequent fabric.
[0017] 3. This high-efficiency napping machine for improving creases and wrinkles has a support frame at the end of the worktable. Multiple toothed rollers are installed inside the support frame, and toothed belts are connected to the toothed rollers. Heated airbag rings are installed outside the toothed belts. The airbag rings are heated and rotated to iron and smooth the fabric, thereby smoothing and cleaning up creases and wrinkles and enhancing the ability to remove creases and wrinkles.

[0020] This invention provides a napping machine for efficiently improving creases and wrinkles, such as... Figure 1-8As shown, the system includes a workbench 1. A traction roller 11 is fixedly installed on the top left side of the workbench 1. Two through slots 12 and 13 are opened at the center of the top of the workbench 1, with through slot 13 located between the two through slots 12. A base 3 is fixedly installed on the top right side of the workbench 1. A fabric output roller 4 is provided above the base 3 and is pivotally connected to the frame of the workbench 1. Both the traction roller 11 and the fabric output roller 4 are controlled by motors to rotate. An ironing assembly is provided on the right side of the fabric output roller 4.
[0021] A pressure roller 14 is fixedly installed below the first channel 12 on the left side, a napping roller 2 is pivotally connected inside the second channel 13, and a roller 7 is pivotally connected below the first channel 12 on the right side. The fabric passes sequentially through the worktable 1, pressure roller 14, napping roller 2, roller 7 along the fabric feeding direction, and then through the fabric output roller 4 and ironing assembly.
[0022] A pre-tension zone is formed between the traction roller 11 and the pressure roller 14, a high-tension zone is formed between the pressure roller 14 and the drum 7, and a tension buffer zone is formed between the drum 7 and the base 3.
[0023] Hollow elastic rubber blocks 31 are symmetrically fixed on the left and right sides of the top of the base 3. The base 3 has grooves that communicate with the elastic rubber blocks 31. A sensing component is provided in the elastic rubber block 31 on the left side, and a force application component is provided in the elastic rubber block 31 on the right side.
[0024] Combined with the appendix Figure 2 It can be seen that the fabric applies downward pressure to the left elastic rubber block 31, and the sensing component feeds the information back to the force application component, which adjusts the distance between the right elastic rubber block 31 and the fabric output roller 4.
[0025] The change in the distance between the fabric output roller 4 and the right-side elastic rubber block 31 alters the clamping force on the fabric. By reducing this clamping force, the fabric is more easily pulled out from between the fabric output roller 4 and the base 3, thus reducing the tension of subsequent fabric.
[0026] The sensing components include a crossbar 32, an elastic sheet 33, a laser pointer 34, and a light-catching module 35. The crossbar 32 abuts against the top of the inner wall of the left elastic rubber block 31. The elastic sheet 33 is located in the groove on the left side of the base 3. The lower end of the elastic sheet 33 is welded to the base 3, and the upper end of the elastic sheet 33 is welded to the body of the crossbar 32.
[0027] The light-harvesting module 35 is fixedly installed inside the base 3. The laser pointer 34 is fixedly installed on the body of the crossbar 32. The light emitted by the laser pointer 34 is angled downward and illuminates the working end of the light-harvesting module 35. The working end of the light-harvesting module 35 is covered with multiple photosensitive units. Since this is a conventional technical method, the specific structure and connection method are not described in detail.
[0028] When not under pressure, the light emitted by the laser pointer 34 forms a light spot at the working end of the light-collecting module 35, and the light spot is located at the center of the working end.
[0029] When pressure is applied, the elastic sheet 33 bends downwards, causing the crossbar 32 to move downwards with the end of the elastic sheet 33 as the fulcrum. During this process, the position of the light spot shifts, and the light-harvesting module 35 senses the change in the position of the light spot and transmits the information to the computer terminal.
[0030] The force-applying components include a second crossbar 36, an arc plate 37, a slide bar 38, and a connecting cloth 310. The second crossbar 36 abuts against the top of the inner wall of the right elastic rubber block 31. The arc plate 37 is located in the groove on the right side of the base 3, and the middle section of the arc plate 37 is pivotally connected to the base 3.
[0031] The upper end of the arc-shaped plate 37 is welded to the body of the crossbar 36. A cavity is formed inside the base 3. The end of the slide rod 38 is slidably engaged with the inside of the cavity. The screw rod 39 is pivotally connected to the cavity. The screw hole 39 is driven to rotate by a motor. The screw rod 39 is threaded through the slide rod 38. The slide rod 38 and the arc-shaped plate 37 are fixedly connected together by the connecting cloth 310.
[0032] When not in operation, the connecting fabric 310 is in a folded and wrinkled state. Working principle: Based on the information fed back by the light-catching module 35, the computer terminal controls the motor to drive the screw 39 to rotate, and the rotation of the screw 39 drives the slide bar 38 to move. The slide bar 38 moves closer to the arc plate 37, and the arc plate 37 sinks due to the large weight at the top, causing the elastic rubber block 31 to move away from the fabric output roller 4.
[0033] When the slide bar 38 moves away from the arc plate 37, the arc plate 37 flips upward, causing the crossbar 36 to approach the fabric output roller 4.
[0034] An electric actuator 15 is fixedly installed at the bottom of the workbench 1. The lower end of the electric actuator 15 is pivotally connected to the end of the roller 7. The roller 7 has a clamping groove 71 along its length for the fabric to pass through. An extension piece 72 is welded to the end of the roller 7. A spring 73 is welded between the extension piece 72 and the lower end of the electric actuator 15.
[0035] The lower end of the electric actuator 15 has a sliding cavity, in which a tension sensor 151 is slidably fitted. A magnetic block 152 is fixedly installed on the inner wall of the sliding cavity near the spring 73. A magnetic ring 153 is fixedly installed on the side of the tension sensor 151 away from the magnetic block 152. A steel wire 74 is welded to the extension plate 72. The steel wire 74 extends into the tension sensor 151 and is fixedly connected to the tension sensor 151. There is a mutual repulsive force between the magnetic block 152 and the magnetic ring 153.
[0036] The height of the roller 7 is changed by extending and retracting the electric actuator 15, thereby adjusting the tension. During normal operation, the spring force of the spring 73 keeps the clamping groove 71 of the roller 7 in a horizontal state, and the steel wire 74 pulls the tension sensor 151, so that the tension sensor 151 is in the middle of the sliding cavity.
[0037] When the electric actuator 15 extends too far, causing excessive tension, the spring force of the spring 73 cannot keep the clamping groove 71 horizontal, causing the clamping groove 71 to tilt. Due to the change in tension, the magnetic force pushes the tension sensor 151 to shift away from the middle of the slide cavity. The tension sensor 151 transmits the information to the computer terminal, which then controls the extension and retraction of the electric actuator 15.
[0038] The ironing assembly includes a bracket 5 and multiple pairs of toothed belts 6. The bracket 5 is welded to the top right end of the workbench 1. Multiple electrically driven toothed rollers 51 are fixedly installed inside the bracket 5. The toothed rollers 51 are conventionally connected to the toothed belts 6. The two toothed belts 6 of the same pair are in contact with each other. The length of the multiple pairs of toothed belts 6 increases sequentially from left to right.
[0039] An airbag ring 61 is fixedly installed on the outer surface of the toothed belt 6. The airbag ring 61 is filled with air. A heating module 62 is fixedly installed on the outer surface of the toothed belt 6. The heating module 62 is covered by the airbag ring 61. A heat-conducting rod 63 is embedded on the outer surface of the airbag ring 61.
[0040] During operation, the heating module 62 heats the air inside the airbag ring 61. After the temperature of the airbag ring 61 rises, it transfers the heat to the heat-conducting rod 63. The heat-conducting rod 63 comes into contact with the fabric and irons the fabric through the heat-conducting rod 63.
[0041] The two toothed belts 6 rotate in opposite directions and move synchronously. The two toothed belts 6 rotate away from each other, gradually and slowly smoothing the fabric from the middle to the two sides, thereby achieving the purpose of ironing and removing the wrinkles of the fabric.
[0042] In summary, this efficient napping machine for improving creases and wrinkles has a traction roller 11, a pressure roller 14, a napping roller 2, a base 3, and a fabric output roller 4 arranged sequentially on the worktable 1. The area between the traction roller 11 and the pressure roller 14 is a pre-tension zone, the area between the pressure roller 14 and the roller 7 is a high-tension zone, and the area between the roller 7 and the base 3 is a tension buffer zone. By setting up multiple tension zones, the fabric gradually adapts to the tension changes, avoiding wrinkles caused by excessively rapid tension changes.
[0043] Furthermore, rubber elastic blocks 31 are provided on both the left and right sides of the base 3. A sensing component is installed in the left rubber elastic block 31, and a force-applying component is installed in the right rubber elastic block 31. The sensing component detects the tension of the fabric on the left side of the base 3 and adjusts the pressure applied by the force-applying component to the fabric output roller 4 accordingly. When the pressure on the left side of the base 3 is too great, the force-applying component reduces the pressure on the fabric output roller 4, making it easier for the fabric to be pulled out from between the fabric output roller 4 and the base 3. This reduces the tension of subsequent fabric.
[0044] Furthermore, a support 5 is set at the end of the workbench 1, and multiple toothed rollers 51 are set inside the support 5. A toothed belt 6 is connected to the toothed rollers 51 through the transmission. A heated airbag ring 61 is installed outside the toothed belt 6. The airbag ring 61 is heated and rotated to iron and flatten the fabric, thereby smoothing out and cleaning creases and wrinkles and enhancing the ability to remove creases and wrinkles.
