[0022] See also Figure 1-5 As shown, a tension adjustment mechanism for a cloth support roller comprises: a rotating shaft 7, square plates 8 are sleeved on both sides of the rotating shaft 7, fixed columns 9 are fixed at the four corners of the two square plates 8, L-shaped rods 10 are sleeved on the middle shaft of the fixed column 9, the bottom of the L-shaped rod 10 is fixed with a first supporting arc plate 11, sliding rods 14 are fixed at the middle position of the rear end surface of the L-shaped rod 10 on both sides of the square plate 8, an annular plate 12 is sleeved on one side of the rotating shaft 7 close to the square plate 8, two sliding grooves 13 are provided in opposite directions on the two annular plates 12 close to the side of the square plate 8, and a fourth cover plate 4 is fixed to the first supporting arc plate 11 at the upper end of one side of the square plate 8 The first cover plate 1 is fixed to the first supporting arc plate 11 at the upper end of the other side of the square plate 8, the second cover plate 2 is fixed to the first supporting arc plate 11 at the lower end of one side of the square plate 8, and the third cover plate 3 is fixed to the first supporting arc plate 11 at the lower end of the other side of the square plate 8. Second supporting arc plates 17 are fixed on both sides of the inner shaft body of the first cover plate 1, and second hydraulic rods 16 are fixed at the bottom center of the two second supporting arc plates 17. The lower ends of the two second hydraulic rods 16 are sleeved with the first hydraulic rods 15, and the bottoms of the two first hydraulic rods 15 are fixed with third supporting arc plates 18, and the two third supporting arc plates 18 are fixedly arranged on both sides of the inner shaft body of the second cover plate 2.

[0023] The two second hydraulic rods 16 are driven upward by the hydraulic pump 6, thereby causing the first cover plate 1 to move upward. The movement of the first cover plate 1 drives the first supporting arc plate 11 and the L-shaped rod 10 fixedly connected thereto to move upward, thereby causing the square plate 8 to rotate. The L-shaped rod 10 is hingedly arranged on the square plate 8. The rotation of the square plate 8 drives the L-shaped rods 10 on both sides to move. The sliding rods 14 at the rear ends of the L-shaped rods 10 on both sides slide in the sliding grooves 13 provided on the ring plate 12, so that the L-shaped rods 10 on both sides move laterally away from each other, thereby causing the third cover plate 3 and the fourth cover plate 4 to move away from each other, so that the diameter of the entire cloth roller increases to The tension can be adjusted quickly to improve work efficiency and product quality. The outer shaft diameter of the ring plate 12 is equal to the inner diameter of the first cover plate 1, the second cover plate 2, the third cover plate 3 and the fourth cover plate 4 combined, so that the ring plate 12 supports the cloth-supporting roller, further increasing the stability of the cloth-supporting roller. The outer shaft curvature of the first supporting arc plate 11, the second supporting arc plate 17 and the third supporting arc plate 18 is consistent with the inner curvature of the first cover plate 1, the second cover plate 2, the third cover plate 3 and the fourth cover plate 4, increasing the contact area between the L-shaped rod 10, the first hydraulic rod 15 and the second hydraulic rod 16 and the cover plate, thereby increasing the stability of the cloth-supporting roller.

[0024] The first cover plate 1, the second cover plate 2, the third cover plate 3 and the fourth cover plate 4 are evenly provided with grooves 5 on their outer shafts, and the grooves 5 are used to increase the friction between the cloth support roller and the cloth, so as to facilitate better transmission and improve product quality. A first fixed rod 19 is fixed between the upper shafts of the two first hydraulic rods 15, and a hydraulic pump 6 is fixed at the top center of the first fixed rod 19. The stability of the cloth support roller is increased by the first fixed rod 19, and the tension of the cloth support roller is adjusted by the hydraulic pump 6. A second fixed rod 20 is fixed between the lower shafts of the two first hydraulic rods 15, and the stability of the entire cloth support roller is further increased by the second fixed rod 20. The first cover plate 1, the second cover plate 2, the third cover plate 3 and the fourth cover plate 4 are combined into a circular design, which is convenient for the rotation of the cloth support roller and the transmission of uniform tension of the cloth. The sliding rod 14 is slidably arranged in the sliding groove 13, and the sliding rod 14 and the L-shaped rod 10 are limitedly slid by the sliding groove 13, so that the first cover plate 1, the second cover plate 2, the third cover plate 3 and the fourth cover plate 4 can move evenly.

[0025] Working principle: The hydraulic pump 6 drives the two second hydraulic rods 16 to move upward, thereby causing the first cover plate 1 to move upward. The movement of the first cover plate 1 drives the first supporting arc plate 11 and the L-shaped rod 10 fixedly connected thereto to move upward, thereby causing the square plate 8 to rotate. The L-shaped rod 10 is hingedly arranged on the square plate 8. The rotation of the square plate 8 drives the L-shaped rods 10 on both sides to move. The sliding rods 14 at the rear ends of the L-shaped rods 10 on both sides slide in the sliding grooves 13 provided on the ring plate 12, so that the L-shaped rods 10 on both sides move laterally away from each other, thereby causing the third cover plate 3 and the fourth cover plate 4 to move away from each other, thereby increasing the size of the entire cloth support roller. The diameter can quickly adjust its tension, which improves work efficiency and product quality. The outer shaft diameter of the ring plate 12 is equal to the inner diameter of the first cover plate 1, the second cover plate 2, the third cover plate 3 and the fourth cover plate 4 combined, so that the ring plate 12 supports the cloth-supporting roller, further increasing the stability of the cloth-supporting roller. The outer shaft curvature of the first supporting arc plate 11, the second supporting arc plate 17 and the third supporting arc plate 18 is consistent with the inner curvature of the first cover plate 1, the second cover plate 2, the third cover plate 3 and the fourth cover plate 4, increasing the contact area between the L-shaped rod 10, the first hydraulic rod 15 and the second hydraulic rod 16 and the cover plate, thereby increasing the stability of the cloth-supporting roller.
