Description

Technical Field

[0001] This invention belongs to the field of fabric processing technology, specifically a cutting and winding device for processing elastic fabrics and its operating method. Background Technology

[0002] Elastic fabric is a type of elastic fabric that combines the advantages of natural and synthetic fibers. It maintains good breathability and comfort while also possessing excellent durability and wrinkle resistance. During the production process, elastic fabric is usually produced continuously and rolled into a large bundle. Although this production method is highly efficient, it needs to be divided into smaller rolls for easier storage and processing later on, making subsequent processing more flexible and efficient. A search revealed a patent, CN214934487U, which describes a rapid cutting device for winding chemical fiber fabrics. The device includes an L-shaped plate with a conveyor roller rotatably mounted on its inner side. A rotating column is mounted on the inner wall of the L-shaped plate via a motor, and a winding roller is slidably mounted on the outer wall of the rotating column. A sliding seat is slidably mounted on the inner wall of the L-shaped plate, and a cutting blade is installed inside the sliding seat. A rotating plate is rotatably mounted on the inner wall of the L-shaped plate via a rotating shaft, and a return spring is sleeved on the outer wall of the rotating shaft. When the winding roller winds the fabric, the thickness of the chemical fiber fabric wound on the outer wall of the winding roller increases. When the thickness increases to a certain extent, the rotating plate deflects to a certain degree under the action of rotational force, causing the cutting blade to slide down and complete the cutting function of the chemical fiber fabric. This achieves autonomous cutting, thus solving the problem in existing technologies where chemical fiber fabrics cannot be automatically cut during winding, resulting in low production efficiency and high manufacturing costs.

[0003] In current cutting and winding devices, the cutting blade is moved to cut by controlling the fabric thickness on the outer wall of the winding roller. As the fabric thickness increases, the cutting blade will gradually move downward. However, when the fabric thickness reaches the cutting thickness, the fabric is still winding. A portion of the fabric will come into contact with the blade and rub against it. This friction will result in low cutting accuracy, which will affect the quality of the fabric and the efficiency of subsequent processing. Summary of the Invention

[0004] The purpose of this invention is to provide a cutting and winding device and its operating method for processing elastic fabrics, so as to solve the problems mentioned in the background art.

A second gear is meshed with one side of the first gear. A second threaded rod is fixedly mounted on the inner wall of the second gear. A second motor is mounted on the top end of the second threaded rod.

[0006] As a further technical solution of the present invention, the clamping assembly includes a first pressure plate and a second pressure plate disposed below the cutting blade. The first pressure plate and the second pressure plate are both installed on the outer wall of the second threaded rod, and the first pressure plate and the second pressure plate are threadedly connected to the second threaded rod.

[0007] As a further technical solution of the present invention, a third pressure plate is slidably installed inside the first pressure plate, and a connecting rod is fixedly installed at the top of the third pressure plate.

[0008] As a further technical solution of the present invention, a first spring is provided at the top of the third pressure plate, and the first spring is installed inside the first pressure plate.

[0009] As a further technical solution of the present invention, the smoothing component includes a smoothing roller disposed on one side of the conveying roller. There are two smoothing rollers. One end of each of the two smoothing rollers is fixedly connected to a second rotating shaft. A slider is installed at the end of each of the two second rotating shafts away from the smoothing roller. Both sliders are disposed inside the side plate.

[0010] As a further technical solution of the present invention, the second rotating shaft is rotatably connected to the slider.

[0011] As a further technical solution of the present invention, both sliders are disposed on the outer wall of the third threaded rod, one slider is slidably connected to the third threaded rod, and the other slider is threadedly connected to the third threaded rod. A first bevel gear is fixedly installed at the bottom end of the third threaded rod, and a second bevel gear is meshed with the bottom end of the first bevel gear. A third rotating shaft is fixedly installed inside the second bevel gear, and a handwheel is fixedly connected to the end of the third rotating shaft away from the second bevel gear. The handwheel is disposed on one side of the side plate.

[0012] As a further technical solution of the present invention, a second movable plate is fixedly installed on one side of one of the sliders, and a first movable plate is provided above the second movable plate. The first movable plate is fixedly installed on the side wall of the first pressure plate.

[0013] As a further technical solution of the present invention, both sliders are slidably connected to the side plate, and a second spring is installed between the two sliders.

[0014] A method for operating a cutting and winding device for processing elastic fabrics includes the following steps: S1: When the fabric is cut and rolled up, first install the elastic fabric on the outer wall of the conveyor roller, and pull one end of the elastic fabric through the two smoothing rollers and between the first pressure plate and the second pressure plate to install it on the outer wall of the take-up roller. S2: Then, adjust the distance between the two smoothing rollers according to the characteristics of the fabric. Turn the handwheel. The rotation of the handwheel drives the rotation of the third rotating shaft. The rotation of the third rotating shaft drives the rotation of the second bevel gear. The rotation of the second bevel gear drives the rotation of the first bevel gear. The rotation of the first bevel gear drives the rotation of the third threaded rod. The rotation of the third threaded rod drives one of the sliders to move. The movement of the slider drives the smoothing roller to move through the second rotating shaft, thereby adjusting the fabric. S3: Then start the first motor. When the first motor starts, it drives the first rotating shaft to rotate. The rotation of the first rotating shaft drives the take-up roller to rotate and take up one end of the elastic fabric. S4: During winding, the thickness of the elastic fabric below is monitored in real time by a distance sensor. When the winding roller is wound to the predetermined thickness, the first motor is turned off and the second motor is started by the PLC. The start of the second motor drives the rotation of the second threaded rod. The rotation of the second threaded rod drives the first pressure plate and the second pressure plate to move relative to each other at the same time, clamping the fabric. S5: At the same time, the first pressure plate moves downward, causing the first moving plate to move downward. When the first moving plate contacts the second moving plate, it causes the second moving plate to move downward. The movement of the second moving plate causes the slider to move. The movement of the slider causes the second rotating shaft and the smoothing roller to move, so that the smoothing roller moves downward and cooperates with the bottom smoothing roller to clamp the fabric. S6: At the same time, the rotation of the second threaded rod drives the rotation of the second gear, the rotation of the second gear drives the rotation of the first gear, the rotation of the first gear drives the rotation of the first threaded rod, the rotation of the first threaded rod drives the connecting block to move downward, and the movement of the connecting block drives the cutting knife to move downward to cut the elastic fabric. S7: After cutting, the second threaded rod is reversed by the second motor to reset the cutting blade. Finally, the worker reinstalls the cut end of the fabric on the outer wall of the take-up roller for continuous processing.

[0015] The beneficial effects of this invention are as follows: This invention utilizes a combination of a winding assembly and a cutting assembly. During elastic fabric processing, the elastic fabric is first mounted on the outer wall of the conveyor roller, with one end passing under the cutting blade and mounted on the outer wall of the winding roller. Then, a first motor is started, driving a first rotating shaft to rotate. This rotation of the first rotating shaft causes the winding roller to rotate and wind up one end of the elastic fabric. During winding, a distance sensor monitors the thickness of the elastic fabric in real time. When the winding roller reaches the predetermined thickness, a PLC controls the first motor to shut off and the second motor to start, driving the cutting blade downwards to cut the elastic fabric. After cutting, the second motor controls the second threaded rod to reverse, resetting the cutting blade. This improves cutting accuracy and ensures the quality of the fabric production.

[0016] By setting up a clamping component, the present invention enables the second threaded rod to rotate and drive the first and second pressure plates to move relative to each other simultaneously when cutting elastic fabric, thereby clamping the fabric to ensure that the fabric remains stable during the cutting process, reducing cutting deviations caused by fabric movement or slippage, and further improving cutting accuracy.

[0017] This invention, through the setting of a smoothing component, allows the fabric to be transferred between two smoothing rollers during winding, smoothing the fabric surface and improving its overall aesthetics. Attached Figure Description

[0020] 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.

[0021] like Figures 1 to 8 As shown in the embodiment of the present invention, a cutting and winding device for processing elastic fabric includes a processing table 1, a side plate 2 is fixedly installed on the top of the processing table 1, and a winding component and a cutting component are installed on the side wall of the side plate 2. The winding assembly includes a winding roller 3 and a conveying roller 30 mounted on the side wall of the side plate 2. Both the winding roller 3 and the conveying roller 30 are rotatably connected to the side plate 2. A distance sensor 29 is provided above the winding roller 3 and is fixedly mounted on the side wall of the side plate 2. A first rotating shaft 4 is fixedly mounted on one end of the winding roller 3 and a first motor 5 is mounted on one end of the first rotating shaft 4. The first motor 5 is located inside the processing table 1. A smoothing assembly is provided on one side of the conveying roller 30. The cutting assembly includes a cutting blade 6 installed on the side wall of the side plate 2. A clamping assembly is provided below the cutting blade 6. A connecting block 7 is fixedly connected to one end of the cutting blade 6. The connecting block 7 is slidably installed inside the side plate 2. A first threaded rod 8 is threadedly connected to the inner wall of the connecting block 7. A first gear 9 is fixedly installed at the top of the first threaded rod 8. A second gear 10 is meshed with one side of the first gear 9. A second threaded rod 11 is fixedly installed on the inner wall of the second gear 10. A second motor 12 is installed at the top of the second threaded rod 11.

[0022] When processing elastic fabric, the elastic fabric is first installed on the outer wall of the conveying roller 30, and one end of the elastic fabric is passed through the bottom of the cutting knife 6 and installed on the outer wall of the take-up roller 3. Then the first motor 5 is started. When the first motor 5 is started, it drives the first rotating shaft 4 to rotate. The rotation of the first rotating shaft 4 drives the take-up roller 3 to rotate and take up one end of the elastic fabric. During winding, the thickness of the elastic fabric below is monitored in real time by the distance sensor 29. When the winding roller 3 is wound to the predetermined thickness, the PLC controls the first motor 5 to shut down and the second motor 12 to start. The start of the second motor 12 drives the rotation of the second threaded rod 11, which in turn drives the rotation of the second gear 10. The rotation of the second gear 10 drives the rotation of the first gear 9, which in turn drives the rotation of the first threaded rod 8. The rotation of the first threaded rod 8 causes the connecting block 7 to move downward. The movement of the connecting block 7 causes the cutting blade 6 to move downward to cut the elastic fabric. After cutting, the second motor 12 controls the second threaded rod 11 to reverse so that the cutting blade 6 resets, improving the cutting accuracy and ensuring the production quality of the fabric.

[0023] like Figures 1 to 8 As shown, the clamping assembly includes a first pressure plate 13 and a second pressure plate 14 disposed below the cutting blade 6. Both the first pressure plate 13 and the second pressure plate 14 are mounted on the outer wall of the second threaded rod 11, and both the first pressure plate 13 and the second pressure plate 14 are threadedly connected to the second threaded rod 11.

[0024] The outer wall of the second threaded rod 11 is provided with two threads, and the two threads are arranged in opposite directions; The first pressure plate 13 is configured in a U-shape, and the cutting blade 6 is slidably connected to the inner wall of the first pressure plate 13; When cutting elastic fabric, the rotation of the second threaded rod 11 drives the first pressure plate 13 and the second pressure plate 14 to move relative to each other, clamping the fabric to ensure that the fabric remains stable during the cutting process, reducing cutting deviations caused by fabric movement or slippage, and further improving cutting accuracy.

[0025] The inner diameter of the first gear 9 is ten times the inner diameter of the second gear 10, where N is a positive integer; The rotational speed of the second gear 10 is greater than that of the first gear 9, which in turn causes the first pressure plate 13 and the second pressure plate 14 to move at a speed greater than that of the cutting blade 6. Ultimately, the first pressure plate 13 and the second pressure plate 14 clamp the fabric before cutting, ensuring stability during cutting.

[0026] like Figure 7 As shown, a third pressure plate 15 is slidably installed inside the first pressure plate 13, and a connecting rod 16 is fixedly installed on the top of the third pressure plate 15.

[0027] When the first pressure plate 13 moves downward, it simultaneously drives the third pressure plate 15 to move downward. When the bottom end of the third pressure plate 15 contacts the second pressure plate 14, it is forced to slide into the interior of the first pressure plate 13, preventing the cutting knife 6 from not cutting when the fabric is pressed. At this time, the first pressure plate 13 and the second pressure plate 14 are still in a moving state to ensure stability during cutting.

[0028] like Figure 7 As shown, a first spring 17 is provided at the top of the third pressure plate 15, and the first spring 17 is installed inside the first pressure plate 13.

[0029] When the third pressure plate 15 is slid into the interior of the first pressure plate 13 under force, the first spring 17 deforms and stores elastic potential energy. When the first pressure plate 13 and the second pressure plate 14 move and reset, the elastic potential energy is released through the first spring 17 to make the third pressure plate 15 move and reset.

[0030] like Figure 3 , Figure 5 and Figure 6 As shown, the smoothing assembly includes a smoothing roller 18 disposed on one side of the conveying roller 30. There are two smoothing rollers 18. One end of each smoothing roller 18 is fixedly connected to a second rotating shaft 19. A slider 20 is installed on the end of each second rotating shaft 19 away from the smoothing roller 18. Both sliders 20 are disposed inside the side plate 2.

[0031] When the fabric is wound up, it is transferred between two smoothing rollers 18, which smooth the fabric surface, making it smoother and improving the overall appearance of the fabric.

[0032] like Figure 5 and Figure 6 As shown, the second rotating shaft 19 is rotatably connected to the slider 20.

[0033] The smoothing roller 18 performs a continuous and dynamic smoothing operation on the fabric. Compared with the static smoothing method, this method is more effective in eliminating wrinkles and unevenness generated in the fabric during the winding process. It can apply pressure evenly to the fabric, ensuring that every part of the fabric is fully smoothed during the winding process, thereby improving the overall flatness of the fabric.

[0034] like Figure 5 and Figure 6As shown, both sliders 20 are disposed on the outer wall of the third threaded rod 21. One slider 20 is slidably connected to the third threaded rod 21, and the other slider 20 is threadedly connected to the third threaded rod 21. A first bevel gear 22 is fixedly installed at the bottom end of the third threaded rod 21. A second bevel gear 23 is meshed with the bottom end of the first bevel gear 22. A third rotating shaft 24 is fixedly installed inside the second bevel gear 23. A handwheel 25 is fixedly connected to the end of the third rotating shaft 24 away from the second bevel gear 23. The handwheel 25 is disposed on one side of the side plate 2.

[0035] Before winding up the fabric, when adjusting the distance between the two smoothing rollers 18, turn the handwheel 25. The rotation of the handwheel 25 drives the rotation of the third rotating shaft 24, which in turn drives the rotation of the second bevel gear 23. The rotation of the second bevel gear 23 drives the rotation of the first bevel gear 22, which in turn drives the rotation of the third threaded rod 21. The rotation of the third threaded rod 21 moves one of the sliders 20. The movement of the slider 20 drives the smoothing rollers 18 to move via the second rotating shaft 19. Adjusting the distance between the two smoothing rollers 18 can accommodate fabrics of different thicknesses or elasticities, ensuring a smoothing effect and improving the adaptability of the device.

[0036] like Figure 5 , Figure 6 and Figure 7 As shown, a second movable plate 27 is fixedly installed on one side of one of the sliders 20, and a first movable plate 26 is provided above the second movable plate 27. The first movable plate 26 is fixedly installed on the side wall of the first pressure plate 13.

[0037] When cutting elastic fabric, the first pressure plate 13 moves downward, causing the first moving plate 26 to move downward. When the first moving plate 26 contacts the second moving plate 27, it causes the second moving plate 27 to move downward. The movement of the second moving plate 27 causes the slider 20 to move. The movement of the slider 20 causes the second rotating shaft 19 and the smoothing roller 18 to move downward, so that the smoothing roller 18 moves downward and cooperates with the bottom smoothing roller 18 to clamp the fabric. This makes it easier for the workers to reinstall the cut end of the fabric on the outer wall of the take-up roller 3 for take-up after the fabric is cut.

[0038] like Figure 5 and Figure 6 As shown, both sliders 20 are slidably connected to the side plate 2, and a second spring 28 is installed between the two sliders 20.

[0039] A method for operating a cutting and winding device for processing elastic fabrics includes the following steps: S1: When the fabric is cut and rolled up, the elastic fabric is first installed on the outer wall of the conveying roller 30, and one end of the elastic fabric is pulled through the two smoothing rollers 18 and between the first pressure plate 13 and the second pressure plate 14 and installed on the outer wall of the winding roller 3. S2: Then, adjust the distance between the two smoothing rollers 18 according to the characteristics of the fabric. Rotate the handwheel 25. The rotation of the handwheel 25 drives the rotation of the third rotating shaft 24. The rotation of the third rotating shaft 24 drives the rotation of the second bevel gear 23. The rotation of the second bevel gear 23 drives the rotation of the first bevel gear 22. The rotation of the first bevel gear 22 drives the rotation of the third threaded rod 21. The rotation of the third threaded rod 21 drives one of the sliders 20 to move. The movement of the slider 20 drives the smoothing roller 18 to move through the second rotating shaft 19, thereby adjusting the fabric. S3: Then start the first motor 5. When the first motor 5 starts, it drives the first rotating shaft 4 to rotate. The rotation of the first rotating shaft 4 drives the take-up roller 3 to rotate and take up one end of the elastic fabric. S4: During winding, the thickness of the elastic fabric below is monitored in real time by the distance sensor 29. When the winding roller 3 is wound to the predetermined thickness, the first motor 5 is turned off and the second motor 12 is started by the PLC. The start of the second motor 12 drives the rotation of the second threaded rod 11. The rotation of the second threaded rod 11 drives the first pressure plate 13 and the second pressure plate 14 to move relative to each other at the same time, clamping the fabric. S5: At the same time, the first pressure plate 13 moves downward, causing the first moving plate 26 to move downward. When the first moving plate 26 contacts the second moving plate 27, it causes the second moving plate 27 to move downward. The movement of the second moving plate 27 causes the slider 20 to move. The movement of the slider 20 causes the second rotating shaft 19 and the smoothing roller 18 to move, so that the smoothing roller 18 moves downward and cooperates with the bottom smoothing roller 18 to clamp the fabric. S6: At the same time, the rotation of the second threaded rod 11 drives the rotation of the second gear 10, the rotation of the second gear 10 drives the rotation of the first gear 9, the rotation of the first gear 9 drives the rotation of the first threaded rod 8, the rotation of the first threaded rod 8 drives the connecting block 7 to move downward, and the movement of the connecting block 7 drives the cutting knife 6 to move downward to cut the elastic fabric. S7: After cutting, the second threaded rod 11 is reversed by the second motor 12 to reset the cutting knife 6. Finally, the worker reinstalls the cut end of the fabric on the outer wall of the take-up roller 3 for continuous processing.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

The rotation of the second threaded rod (11) drives the first pressure plate (13) and the second pressure plate (14) to move relative to each other at the same time to clamp the fabric. S5: At the same time, the first pressure plate (13) moves downward, causing the first moving plate (26) to move downward. When the first moving plate (26) contacts the second moving plate (27), it causes the second moving plate (27) to move downward. The movement of the second moving plate (27) causes the slider (20) to move. The movement of the slider (20) causes the second rotating shaft (19) and the smoothing roller (18) to move, so that the smoothing roller (18) moves downward and cooperates with the bottom smoothing roller (18) to clamp the fabric. S6: At the same time, the rotation of the second threaded rod (11) drives the rotation of the second gear (10), the rotation of the second gear (10) drives the rotation of the first gear (9), the rotation of the first gear (9) drives the rotation of the first threaded rod (8), the rotation of the first threaded rod (8) drives the connecting block (7) to move downward, and the movement of the connecting block (7) drives the cutting knife (6) to move downward to cut the elastic fabric. S7: After cutting, the second threaded rod (11) is reversed by the second motor (12) to reset the cutting knife (6). Finally, the worker reinstalls the cut end of the fabric on the outer wall of the take-up roller (3) for continuous processing.
