Description

Technical Field

[0001] This invention relates to the field of fabric winding technology, specifically to a fabric production device and method for winding and rolling fabric to a fixed width. Background Technology

[0002] Greige fabric is a basic product in the textile industry. It refers to raw fabric that has not been dyed, printed, or otherwise finished. The quality of greige fabric directly affects the quality of subsequent processed products. Therefore, the greige fabric winding process is very important. Greige fabric winding is an important step in textile production. It involves sorting and winding the woven greige fabric for subsequent processing. During the greige fabric winding process, ensuring the flatness and tightness of the fabric is very important, as it directly affects the quality and efficiency of subsequent processing. In addition, greige fabric production will produce loose threads that adhere to the surface of the greige fabric, and the greige fabric may shift due to accidents during winding, affecting the winding efficiency. To address these issues, we propose a fixed-width winding and rolling device and method for greige fabric production. Summary of the Invention

[0006] Preferably, the cleaning assembly includes a connecting plate fixedly connected to a support frame, extension rods fixedly connected to both sides of the connecting plate, a connecting block fixedly connected to the front end of the extension rod, a sliding cylinder fixedly connected to the front end of the connecting block, a sliding rod slidably connected to the inner sides of the two sets of sliding cylinders, a pressure rod fixedly connected to the lower end of the sliding rod, rotating plates rotatably connected to both sides of the pressure rod, and a cleaning plate fixedly connected to the lower ends of the four sets of rotating plates.

[0007] Preferably, an eccentric wheel is fixedly connected to the rear end of the connecting plate, and an eccentric wheel is rotatably connected to the front end of the connecting plate. The eccentric wheel is fixedly connected to the output end of the motor, and two sets of rotating columns are rotatably connected to the rear end of the slide rod, with the eccentric wheel located between the two sets of rotating columns.

[0008] Preferably, the leveling component includes a support plate fixedly connected to the upper end of the mounting rod, a fixing plate fixedly connected to the upper ends of the two sets of support plates, a threaded rod rotatably connected between the two sets of support plates, a slider threadedly connected to the outer side of the threaded rod, the slider slidably connected to the fixing plate, a pressure block fixedly connected to the lower end of the slider, and a clamping piece fixedly connected to the lower end of the pressure block. The clamping piece is arc-shaped and is locked onto the outer side of the top shaft.

[0009] Preferably, a crossbar is fixedly connected to the front end of the clamping piece, a connecting cylinder is fixedly connected to the front end of the crossbar, a connecting ring is fixedly connected to the outer side of the connecting cylinder, a sliding groove is provided on the outer side of the connecting ring, a rotating ring is rotatably connected to the inner side of the sliding groove, a connecting ring is fixedly connected to the outer side of the rotating ring, a connecting handle is fixedly connected to the outer side of the connecting ring, and a blade is fixedly connected to one end of the connecting handle. The blade is fan-shaped.

[0010] Preferably, a first connecting shaft is fixedly connected to one side of the crossbar, a rotating ring is rotatably connected to the outer side of the first connecting shaft, the rotating ring is in close contact with the top shaft, an offset column is fixedly connected to one side of the rotating ring, a second connecting shaft is fixedly connected to one side of the connecting handle, and a push rod is rotatably connected between the second connecting shaft and the offset column.

[0011] Preferably, a rocker arm is rotatably connected to one side of the connecting cylinder, a pressure roller is rotatably connected to one side of the rocker arm, a rotating shaft is rotatably connected to the inner side of the connecting cylinder, the rotating shaft is fixedly connected to the rocker arm, and a spring is provided on the outer side of the rotating shaft, the spring being located on the inner side of the connecting cylinder.

[0012] A method for producing fabric with a fixed width of winding and rolling includes the following steps: Step 1: Passing the fabric through the top shaft and using a winding frame to wind the fabric. When the fabric becomes loose, the pressure of the mounting rod on the pressure sensor will decrease. At this time, the cylinder pushes the push plate to move up, causing the spring to push the mounting rod to move up, thereby causing the top shaft to lift the fabric and straighten it, making it easier for the winding frame to wind it up.

[0013] Step 2: Start the motor to drive the eccentric wheel to rotate. At this time, the eccentric wheel will drive the rotating column to rotate and use the rotating column to drive the slide rod to slide inside the slide cylinder. Then, the pressure rod will drive the cleaning sheet to slide on the fabric to smooth out the wrinkles on the fabric. At the same time, the rotating sheet can make the cleaning sheet stick tightly to the fabric.

[0014] Step 4: Rotating the threaded rod can drive the slider to move at the lower end of the fixed plate. At the same time, the pressure block drives the clamp to slide on the outside of the top shaft, restricting the fabric and preventing it from shifting. When the fabric is rolled up, it will drive the top shaft to rotate, which will drive the ring to rotate, thereby driving the push rod to swing. This will drive the blade to move up and down through the connecting handle to cut the side of the fabric. At the same time, the connecting handle will drive the connecting ring to rotate the ring inside the groove.

[0015] Step 5: The pressure roller can hold down both sides of the fabric, making it easier for the blade to cut. The swing arm can move the pressure roller easily, and the spring can drive the rotating shaft to rotate, making it easy for the pressure roller to return to its original position.

[0016] Compared with the prior art, the present invention provides a device and method for winding and rolling fabric to a fixed width, which has the following advantages:

[0017] 1. This is a fixed-width winding and rolling device for producing raw fabric. The top shaft can hold the raw fabric in place, keeping it taut and preventing it from loosening during winding. A pressure sensor can determine the tightness of the mounting rod, thereby determining the pressure of the raw fabric on the top shaft. This allows the cylinder to adjust the position of the top shaft, ensuring the winding effect of the winding frame. A spring can reduce the vibration of the mounting rod, facilitating the spring mounting rod to measure the pressure of the raw fabric.

[0018] 2. This is a fixed-width winding and rolling device for producing greige fabric. The eccentric wheel is driven by a motor to rotate. The eccentric wheel drives the rotating column to rotate and the rotating column drives the slide rod to slide inside the slide cylinder. Then, the pressure rod drives the cleaning plate to slide on the greige fabric to smooth out the wrinkles on the greige fabric. At the same time, the rotating plate can make the cleaning plate stick to the greige fabric, which is convenient for the cleaning plate to clean the surface of the greige fabric.

[0019] 3. This type of fabric production fixed width winding and rolling device uses a threaded rod to drive a slider to move at the lower end of a fixed plate. At the same time, a pressure block drives a clamping plate to slide on the outside of a top shaft to restrict the fabric and prevent it from shifting. The top shaft drives a rotating ring, which in turn drives a push rod to swing, making it easier for the blade to clean the thread ends on both sides of the fabric, further ensuring the quality of the fabric. The pressure roller can press down on both sides of the fabric, making the two ends of the fabric stable and facilitating the cutting of the blade. Attached Figure Description

[0034] In this embodiment, the cleaning component 3 includes a connecting plate 31 fixedly connected to the support frame 2. Extension rods 34 are fixedly connected to both sides of the connecting plate 31. A connecting block 35 is fixedly connected to the front end of the extension rod 34.

A cleaning plate 311 is fixedly connected to the lower end of the four sets of rotating plates 310.

[0035] Specifically, the rotating plate 310 allows the cleaning plate 311 to adhere tightly to the fabric, making it easier for the cleaning plate 311 to clean the surface of the fabric. The pressure rod 39 drives the cleaning plate 311 to slide on the fabric, smoothing out the wrinkles on the fabric.

[0036] In this embodiment, an eccentric wheel 33 is fixedly connected to the rear end of the connecting plate 31, and an eccentric wheel 33 is rotatably connected to the front end of the connecting plate 31.

[0037] Specifically, the motor 32 drives the eccentric wheel 33 to rotate, which in turn drives the rotating column 38 to rotate and the rotating column 38 drives the slide rod 37 to slide inside the slide cylinder 36.

[0038] In this embodiment, the leveling component 7 includes a support plate 71 fixedly connected to the upper end of the mounting rod 5. The upper ends of the two sets of support plates 71 are fixedly connected to a fixing plate 72. A threaded rod 73 is rotatably connected between the two sets of support plates 71. A slider 74 is threadedly connected to the outer side of the threaded rod 73. The slider 74 is slidably connected to the fixing plate 72. A pressure block 75 is fixedly connected to the lower end of the slider 74. A clamping piece 76 is fixedly connected to the lower end of the pressure block 75. The clamping piece 76 is arc-shaped and is clamped on the outer side of the top shaft 6.

[0039] Specifically, rotating the threaded rod 73 can drive the slider 74 to move at the lower end of the fixed plate 72, while the pressure block 75 drives the clamping piece 76 to slide on the outside of the top shaft 6 to restrict the fabric and prevent the fabric from shifting.

[0040] In this embodiment, a crossbar 77 is fixedly connected to the front end of the clamping piece 76, a connecting cylinder 79 is fixedly connected to the front end of the crossbar 77, a connecting ring 78 is fixedly connected to the outer side of the connecting cylinder 79, a sliding groove 714 is provided on the outer side of the connecting ring 78, a rotating ring 715 is rotatably connected to the inner side of the sliding groove 714, a connecting ring 716 is fixedly connected to the outer side of the rotating ring 715, a connecting handle 717 is fixedly connected to the outer side of the connecting ring 716, and a blade 718 is fixedly connected to one end of the connecting handle 717. The blade 718 is fan-shaped.

[0041] Specifically, when the fabric is wound up, the top shaft 6 will rotate, the top shaft 6 will drive the rotating ring 720 to rotate, which in turn will drive the push rod 722 to swing, thereby using the connecting handle 717 to drive the blade 718 to move up and down to cut the side of the fabric.

[0042] In this embodiment, a first connecting shaft 719 is fixedly connected to one side of the crossbar 77, and a rotating ring 720 is rotatably connected to the outer side of the first connecting shaft 719. The rotating ring 720 is in close contact with the top shaft 6. An offset column 721 is fixedly connected to one side of the rotating ring 720, and a second connecting shaft 723 is fixedly connected to one side of the connecting handle 717. A push rod 722 is rotatably connected between the second connecting shaft 723 and the offset column 721.

[0043] A rocker arm 710 is rotatably connected to one side of the connecting cylinder 79, and a pressure roller 711 is rotatably connected to one side of the rocker arm 710. A rotating shaft 712 is rotatably connected to the inner side of the connecting cylinder 79. The rotating shaft 712 is fixedly connected to the rocker arm 710. A spring piece 713 is provided on the outer side of the rotating shaft 712. The spring piece 713 is located on the inner side of the connecting cylinder 79.

[0044] Specifically, the connecting handle 717 drives the connecting ring 716 to make the rotating ring 715 rotate inside the groove 714. The pressure roller 711 can press down both sides of the fabric, making it easier for the blade 718 to cut. The rocker arm 710 can facilitate the movement of the pressure roller 711. The spring piece 713 can drive the rotating shaft 712 to rotate, making it easier for the pressure roller 711 to return to its original position.

[0045] A method for producing fabric with a fixed width of winding and rolling includes the following steps: Step 1: Passing the fabric through the top shaft 6 and using the winding frame 1 to wind the fabric. When the fabric becomes loose, the pressure of the mounting rod 5 on the pressure sensor 12 will decrease. At this time, the cylinder 8 pushes the push plate 9 upward, causing the spring 10 to push the mounting rod 5 upward, thereby causing the top shaft 6 to lift the fabric and straighten it, making it easier for the winding frame 1 to wind it up.

[0046] Step 2: Start the motor 32 to drive the eccentric wheel 33 to rotate. At this time, the eccentric wheel 33 will push the rotating column 38 to rotate and use the rotating column 38 to drive the slide bar 37 to slide inside the slide cylinder 36. Then, the pressure bar 39 will drive the cleaning plate 311 to slide on the fabric to smooth out the wrinkles on the fabric. At the same time, the rotating plate 310 can make the cleaning plate 311 stick to the fabric.

[0047] Step 4: Rotating the threaded rod 73 can drive the slider 74 to move at the lower end of the fixed plate 72. At the same time, the pressure block 75 drives the clamping piece 76 to slide on the outside of the top shaft 6 to restrict the fabric and prevent it from shifting. When the fabric is rolled up, it will drive the top shaft 6 to rotate. The top shaft 6 will drive the rotating ring 720 to rotate, which in turn drives the push rod 722 to swing. This will drive the blade 718 to move up and down through the connecting handle 717 to cut the side of the fabric. At the same time, the connecting handle 717 will drive the connecting ring 716 to make the rotating ring 715 rotate inside the groove 714.

[0048] Step 5: The pressure roller 711 can press down both sides of the fabric to facilitate cutting by the blade 718. The swing rod 710 can facilitate the movement of the pressure roller 711. The spring piece 713 can drive the rotating shaft 712 to rotate, so that the pressure roller 711 can return to its original position.

[0049] It should be noted that during use, the fabric is passed through the top shaft 6, and the winding frame 1 winds up the fabric. When the pressure of the mounting rod 5 on the pressure sensor 12 changes, the cylinder 8 will start, driving the push plate 9 to move up or down, causing the spring 10 to push the mounting rod 5 to move, which in turn drives the top shaft 6 to move, changing the tension of the fabric and facilitating the winding frame 1 to wind it up. The starting motor 32 drives the eccentric wheel 33 to rotate. At this time, the eccentric wheel 33 will drive the rotating column 38 to rotate, and the rotating column 38 will drive the sliding rod 37 to slide inside the sliding cylinder 36. Then, the pressure rod 39 will drive the cleaning plate 311 to slide on the fabric, smoothing out the wrinkles on the fabric. At the same time, the rotating plate 310 can make the cleaning plate 311 stick tightly to the fabric. Rotating the threaded rod 73 can drive the sliding rod 311 to slide on the fabric. Block 74 moves at the lower end of the fixed plate 72, while the pressure block 75 drives the clamping piece 76 to slide on the outside of the top shaft 6 to restrict the fabric and prevent it from shifting. When the fabric is rolled up, it will drive the top shaft 6 to rotate, which will drive the rotating ring 720 to rotate, which in turn will drive the push rod 722 to swing. This will drive the blade 718 to move up and down through the connecting handle 717 to cut the side of the fabric. At the same time, the connecting handle 717 will drive the connecting ring 716 to make the rotating ring 715 rotate inside the slide groove 714. The pressure roller 711 can press down on both sides of the fabric to facilitate the cutting of the blade 718. The swing rod 710 can facilitate the movement of the pressure roller 711, and the spring piece 713 can drive the rotating shaft 712 to rotate, so that the pressure roller 711 can return to its original position.
