Description

Technical Field

[0001] This utility model relates to the field of correction device technology, and in particular to a fabric correction device. Background Technology

[0002] Fabric correction devices are used to transport fabric and prevent it from shifting during transport, ensuring the smooth progress of subsequent fabric processing steps and increasing the yield of finished products.

[0003] For example, patent CN118002434A discloses a coating machine conveyor roller correction device, including a base. Two symmetrical second support columns with identical mechanisms are welded to the middle of the upper surface of the base near both ends. The same loading plate is welded to the opposite sides of the two second support columns near the middle, and a correction mechanism is installed at the top of the loading plate. The correction mechanism includes a second roller and a correction cylinder. By setting the correction mechanism, this invention can quickly adjust the position and angle of the correction cylinder to restore the fabric to the correct position, realizing dynamic adjustment of the fabric angle. It also includes a first roller, through which the fabric passes under the first roller, applying an additional force to the fabric, which can tighten the fabric and ensure that the fabric can stick tightly to the correction cylinder, improving the correction effect and avoiding downtime or reduced production efficiency due to fabric deviation. This helps to improve production efficiency and reduce production costs.

[0004] The problem with the above technology is that when the fabric is deviated beyond the two ends of the correction cylinder, the correction cylinder cannot correct the fabric back to the center position, thereby reducing the yield of fabric processing.

[0005] To address this issue, a fabric correction device is proposed to solve the aforementioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a fabric correction device that can smoothly transport fabric and increase the yield of processed fabric.

[0007] The technical solution adopted by this utility model to solve the problem is: a fabric correction device, including a frame, a first roller and a second roller respectively arranged on the front and rear sides of the frame, a correction component that can move left and right arranged in the middle of the frame, a third roller that can move vertically arranged on the correction component, a fourth roller arranged on the front and rear sides of the third roller, and a first clamping device and a second clamping device respectively arranged on the sides of the first roller and the second roller.

[0008] As a further improvement to the above technical solution, both the first clamping device and the second clamping device include a clamping seat and a clamping arm. A cylinder is provided on the top of the clamping seat, and the output shaft of the cylinder extends to the bottom of the top of the clamping seat. The clamping arm is connected to the output shaft of the cylinder.

[0009] As a further improvement to the above technical solution, the correction assembly includes a correction frame, a first motor and a ball screw connected to the first motor are provided on the top of the correction frame, the ball screw extends to the bottom of the top of the correction frame, the lower end of the ball screw is connected to a fixed seat, and the third roller is fixedly arranged at the bottom of the fixed seat.

[0010] As a further improvement to the above technical solution, the left and right ends of the correction frame are provided with vertical guide rails, and the left and right ends of the fixing base are slidably connected to the guide rails respectively.

[0011] As a further improvement to the above technical solution, the bottom of the frame is provided with a base plate, and a slide rail and a second motor are provided on the base plate. The bottom of the correction frame is slidably connected to the slide rail, and the second motor is used to drive the correction frame to slide.

[0012] As a further improvement to the above technical solution, the front end and the rear end of the frame are respectively provided with a first support and a second support, and the first roller and the second roller are rotatably connected to the first support and the second support, respectively.

[0013] The beneficial effects of this utility model are as follows: In use, the fabric passes sequentially through the first roller, the first clamping device, the fourth roller at the front, below the third roller, the fourth roller at the rear, the second clamping device, and the second roller. The third roller presses down on the fabric, tightening it and causing it to adhere to the first, second, and fourth rollers. When the fabric deviates beyond the edge of the third or fourth roller, the first and second clamping devices clamp the fabric, and the third roller moves upward to release the fabric, thereby releasing the first roller, the second roller, and the fourth roller. The tension of the fabric exerted by the second, third, and fourth rollers allows the correction assembly to move left and right to return to the center position, leaving sufficient length on the edges of the third and fourth rollers for fabric correction. Subsequently, the third roller can continue to press the fabric downwards, causing it to adhere to the first, second, and fourth rollers. This ensures that the fabric remains taut throughout the conveying process. The first and second clamping devices can release the fabric, allowing the fabric to continue being conveyed for correction processing. This device increases the yield rate of the processed fabric.

[0024] Reference Figures 1 to 5A fabric correction device includes a frame 1, a first roller 2 and a second roller 3 respectively arranged on the front and rear sides of the frame 1, a correction component 4 capable of moving left and right arranged in the middle of the frame 1, a third roller 51 capable of moving in the vertical direction arranged on the correction component 4, a fourth roller 44 arranged on the front and rear sides of the third roller 51, and a first clamping device 61 and a second clamping device 62 respectively arranged on the inner ends of the first roller 2 and the second roller 3.

[0025] The arrows in the attached diagram indicate the direction of fabric conveying. The device is equipped with sensors for detecting fabric deviation, which are not shown in the diagram.

[0026] In use, the fabric passes sequentially through the first roller 2, the first clamping device 61, the fourth roller 44 on the front side, the fourth roller 44 below the third roller 51 and on the rear side, the second clamping device 62 and the second roller 3. The fabric can be tightened by pressing down on the third roller 51, so that the fabric is attached to the first roller 2, the second roller 3 and the fourth roller 44. When the fabric shifts to the left or right, the correction component 4 can move to the left or right, and under the action of the friction of the third roller 51 and the fourth roller 44, the fabric is pulled back to the center position.

[0027] When the fabric deviates beyond the edge of the third roller 51 or the fourth roller 44, the first clamping device 61 and the second clamping device 62 can clamp the fabric, the third roller 51 can move upward to release the fabric, thereby relieving the tension of the first roller 2, the second roller 3, the third roller 51 and the fourth roller 44 on the fabric, and the correction component 4 can move left and right to return to the center position, so that the edges of the third roller 51 and the fourth roller 44 leave enough length for the fabric to be corrected.

[0028] When the correction component 4 returns to the center position, the third roller 51 can continue to press the fabric downwards, so that the fabric adheres to the first roller 2, the second roller 3 and the fourth roller 44, which can ensure that the fabric is always in a taut state during the conveying process. The first clamping device 61 and the second clamping device 62 can release the fabric, thereby continuing to convey the fabric for correction processing. This device can increase the yield of fabric processing.

[0029] In a preferred embodiment, both the first clamping device 61 and the second clamping device 62 include a clamping seat 63 and a clamping arm 64. A cylinder 65 is provided on the top of the clamping seat 63, and the output shaft of the cylinder 65 extends to the lower part of the top of the clamping seat 63. The clamping arm 64 is connected to the output shaft of the cylinder 65.

[0030] When conveying the fabric, the fabric is located between the clamping seat 63 and the clamping arm 64. The cylinder 65 can drive the clamping arm 64 to move up and down to clamp or release the fabric.

[0031] In a preferred embodiment, the correction assembly 4 includes a correction frame 41. A first motor 52 and a ball screw 53 connected to the first motor 52 are provided on the top of the correction frame 41. The ball screw 53 extends to the bottom of the top of the correction frame 41. A fixed seat 54 is connected to the lower end of the ball screw 53. A third roller 51 is fixedly disposed at the bottom of the fixed seat 54.

[0032] The first motor 52 drives the ball screw 53 to move the fixed seat 54 up and down, thereby causing the third roller 51 to press down or release the fabric.

[0033] In a preferred embodiment, in order to increase the stability of the fixed base 54, both the left and right ends of the correction frame 41 are provided with vertical guide rails 55, and the left and right ends of the fixed base 54 are slidably connected to the guide rails 55 respectively.

[0034] In a preferred embodiment, a base plate 11 is provided at the bottom of the frame 1, and a slide rail 42 and a second motor 43 are provided on the base plate 11. The bottom of the correction frame 41 is slidably connected to the slide rail 42, and the second motor 43 is used to drive the correction frame 41 to slide.

[0035] When the fabric deviates, the second motor 43 can drive the correction frame 41 to slide left and right on the slide rail 42, thereby correcting the fabric.

[0036] In a preferred embodiment, a first support 12 and a second support 13 are respectively provided at the front and rear ends of the frame 1, and the first roller 2 and the second roller 3 are rotatably connected to the first support 12 and the second support 13 respectively.

[0037] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings under the inventive concept of this utility model, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
