Description

Technical Field

[0001] The present application relates to the technical field of cloth spreading machines, and in particular to an automatic deviation-correcting device for a cloth spreading machine. Background Art

[0002] In the textile, printing and dyeing, and garment processing industries, cloth spreading machines are key production equipment, and their stability and precision directly affect the quality of the products. The cloth spreading machines currently widely used in the market mostly use mechanical or simple electronic sensors to achieve the laying and positioning of the cloth. However, under long-term high-speed operation, due to factors such as cloth material, tension changes, and mechanical wear, cloth deviation problems often occur. Existing automatic deviation correction devices mostly rely on a single sensor detection and mechanical adjustment mechanism, which has disadvantages such as slow response speed, low adjustment accuracy, and poor adaptability to complex working conditions. These problems are particularly prominent when dealing with wide, heavy, or easily slippery cloths, seriously affecting production efficiency and product quality.

[0003] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The embodiment of the present application discloses an automatic deviation correction device for a cloth spreading machine. Figure 1, including a cloth pulling machine frame 1, the cloth pulling machine frame 1 is provided with a mounting plate 2, the inner wall of the mounting plate 2 is installed with a mounting bearing 6, a rotating shaft 7 is rotated in the mounting bearing 6, a servo motor 3 is installed on the outer wall of the mounting plate 2, the output end of the servo motor 3 passes through the inner wall of the mounting plate 2 and is transmitted to the rotating shaft 7, a cloth pulling roller 5 is fixed on the outer wall of the rotating shaft 7, which can drive the cloth pulling roller 5 to rotate and wind the cloth, and a fixed plate 12 is rotatably provided on both sides of the outer wall of the cloth pulling roller 5, and a movable correcting disk 11 is provided on the inner side of the fixed plate 12, the correcting disk 11 is slidably adapted to the cloth pulling roller 5, and a number of springs 13 are connected between the correcting disk 11 and the fixed plate 12. Due to the elasticity of the spring 13, the correcting disk 11 can be driven to slide and adapt outside the cloth pulling roller 5, which is convenient for adapting to cloths of different widths.

[0020] like Figure 3 As shown, a correction guide roller 17 is provided between the two correction disks 11, and a slide 14 is provided on one side of the surface of the correction disk 11. The slide 14 is set to a semi-arc shape, and a matching connecting shaft 15 is slidably installed in the slide 14. One end of the connecting shaft 15 extends to the outside of the slide 14 and is connected with a fastener 16, and the connecting shaft 15 is movably connected to the correction guide roller 17. Therefore, the guiding correction position of the correction guide roller 17 can be adjusted by pushing the connecting shaft 15 to slide in the slide 14. After adjusting the position, the fastener 16 is fixed to position the connecting shaft 15, and the ends of the two connecting shafts 15 that are close to each other extend to the inside of the correction guide roller 17 respectively, and a group of elastic parts are provided between the connecting shaft 15 and the inner wall of the correction guide roller 17. Therefore, as the two correction disks 11 approach each other, the connecting shaft 15 can move accordingly in the correction guide roller 17.

[0021] Combine Figure 2 As shown, a support assembly is provided at the bottom of the correction disk 11, and the support assembly includes a slide rail 4 and a sliding block 8 slidingly arranged on the outside of the slide rail 4. The slide rail 4 is symmetrically fixed to the bottom end of the inner wall of the mounting plate 2, and a connecting rod 9 is connected between the two sliding blocks 8. Since the outer walls of the two sliding blocks 8 at one end away from each other are fixed with a connecting arm 10, and the top of the connecting arm 10 is fixed to the outer wall of the correction disk 11, as the correction disk 11 moves, the connecting arm 10 will push the sliding block 8 to slide outside the slide rail 4, which is convenient for adapting to the positioning of fabrics of different widths, further improving the correction effect on the fabric, and avoiding offset.

[0022] The implementation principle of the automatic correction device of the cloth stretching machine in the embodiment of the present application is as follows: one end of the cloth is fixed on the cloth stretching roller 5 in advance, and then the correction disk 11 is adjusted to be close to both sides of the cloth according to the width of the cloth. The elasticity of the spring 13 provides the movable supporting force of the correction disk 11, which is convenient for adapting to the correction space of cloths of different widths. As the correction disk 11 moves, the connecting arm 10 pushes the sliding block 8 to slide to the corresponding position outside the slide rail 4, further enhancing the positioning effect and avoiding offset. Then, according to the guiding requirements of the cloth, the connecting shaft 15 is pushed on the slide rail 1 4, and then positioned by the fastener 16, and then conveniently drive the deflection correction guide roller 17 to adjust to the corresponding position of the outer wall of the cloth-pulling roller 5 to guide it, and as the deflection correction disk 11 moves, the connecting shafts 15 on both sides will move synchronously in the deflection correction guide roller 17, which is convenient for adapting to the deflection correction of fabrics of different widths and thicknesses. If necessary, the sliding block 8 can also be fixed to the slide rail 4 by screws to improve the overall stability. Subsequently, the servo motor 3 is used to drive the cloth-pulling roller 5 to rotate to pull the fabric, and the deflection correction guide roller 17 guides the outside of the fabric for deflection correction.
