Description

Technical Field

[0001] The utility model relates to the technical field of cloth processing, in particular to a tension regulating device for cloth transmission. Background Art

[0002] Fabric is a commonly used material in decoration. It comes in various types and is widely used in wall decoration, partitions and background processing. During the production process, the fabric on the unwinding roller is often conveyed to the processing equipment through a conveyor roller.

Example

[0025] See also Figure 1-5 , the utility model provides a technical solution:

[0026] A tensioning and adjusting device for cloth conveying, comprising a bottom plate 1, a symmetrical supporting plate 2 is fixedly arranged at the left end of the upper side wall of the bottom plate 1, a cloth roll 3 is rotatably arranged between the two supporting plates 2 through a mounting mechanism, a fixing rod 4 is fixedly arranged at the rear of the right end of the upper side wall of the bottom plate 1, a fixing plate 5 is fixedly arranged at the upper end of the fixing rod 4, and a connecting plate 6 is fixedly arranged on the left side wall of the fixing plate 5;

[0027] A guide mechanism is fixedly provided at the left end of the front side wall of the connecting plate 6, and a symmetrical sliding groove is opened at the left end of the front side wall of the fixed plate 5. Limit rods 7 are fixedly provided inside the two sliding grooves, and sliders 8 are slidably provided outside the two limit rods 7. The ends of the two sliders 8 that are away from each other are located outside the limit rod 7 and are sleeved with a first spring 9. The ends of the two sliders 8 that are close to each other are located outside the limit rod 7 and are sleeved with a second spring 10. One end of the two first springs 9 is fixedly connected to the inner wall of the sliding groove, and the other end is fixedly connected to the side wall of the slider 8. One end of the two second springs 10 is fixedly connected to the side wall of the moving block 11, and the other end is fixedly connected to the side wall of the slider 8. The outside of the two limit rods 7 is located at the end close to the two second springs 10 and is slidably provided with a moving block 11. The front side walls of the two sliders 8 are rotatably provided with a first supporting wheel 12, and the right end of the front side wall of the fixed plate 5 is rotatably provided with a second supporting wheel 13.

[0028] A bracket 14 is fixedly provided on the front side wall of the fixed plate 5, and a screw rod 15 is rotatably provided inside the bracket 14, and the other end of the screw rod 15 extends to the outside of the bracket 14 and is fixedly provided with a rotating block 16, and an adjusting block 17 is threadedly provided on the rod wall of the screw rod 15, and U-shaped blocks 18 are fixedly provided on the upper side wall and the lower side wall of the adjusting block 17, and adjusting plates 19 are rotatably provided inside the two U-shaped blocks 18, and the other ends of the two adjusting plates 19 are rotatably connected to the front side wall of the moving block 11, and by rotating the rotating block 16, the rotating block 16 drives the screw rod 15 of the side wall to rotate, and the screw rod 15 drives the adjusting block 17 threadedly connected to the rod wall to move, and the adjusting block 17 drives the U-shaped block 18 of the side wall to move, and the U-shaped block 18 drives the adjusting plates 19 at both ends to move, thereby pushing or pulling the moving block 11.

[0029] When conveying fabric with greater elasticity, it is necessary to reduce the adjustment range of the tension adjusting device. This is because if the fabric has greater elasticity, the two first support wheels 12 will be driven to move up and down over a greater range during pulling. At this time, the winding will be very unstable and easy to be wound loosely. When conveying fabric with less elasticity, it is necessary to increase the adjustment range of the tension adjusting device. When the fabric is pulled, the two first support wheels 12 have a greater range of upward and downward movement, which effectively avoids damage to the fabric caused by pulling due to a small range of movement.

[0030] The mounting mechanism comprises two rotating rods 20, the ends of the two rotating rods 20 which face away from each other are rotatably connected to the side walls of the support plate 2 through bearings, the ends of the two rotating rods 20 which are close to each other are fixedly provided with sleeves 21, the upper side walls and the lower side walls of the two sleeves 21 are threadedly provided with fastening bolts 22, and the two ends of the cloth roll 3 are plugged and fixed inside the sleeves 21 by the fastening bolts 22, so that the cloth roll 3 can be installed and fixed conveniently, and a new cloth roll 3 can be quickly replaced.

[0031] The guide mechanism includes a guide block 23, which is fixedly connected to the front side wall of the connecting plate 6. A symmetrical cavity is opened inside the guide block 23, and the left and right walls of the two cavities are both provided with cloth inlets. Symmetrical guide wheels 24 are rotatably arranged inside the two cavities.

[0032] A cleaning mechanism is provided at the right end of the guide mechanism, and the cleaning mechanism includes a cleaning box 25, which is fixedly connected to the front side wall of the connecting plate 6. Symmetrical slide grooves are provided on the inner wall of the cleaning box 25, and mounting blocks 26 are slidably provided inside the symmetrical slide grooves. A cleaning brush 27 is fixedly provided between two groups of symmetrical mounting blocks 26, which can clean the debris attached to both sides of the cloth to ensure the cleanliness of the cloth surface.

[0033] A protective cover plate 28 is fixedly provided at the front end of the fixed plate 5 through a connecting mechanism, and the connecting mechanism includes a fixing tube 29, which is fixedly connected to the front side wall of the fixed plate 5, and a plug 30 is fixedly provided on the rear side wall of the protective cover plate 28, and the plug 30 is plugged into the fixed tube 29. When the cloth is being conveyed, the protective cover plate 28 can be fixed at the front end to protect the cloth from being disturbed by external conditions.

[0034] Working principle:

[0035] First, fix the cloth roll 3 between the two support plates 2, and the cloth passes through the guide block 23 and the cleaning box 25, and passes around the two first support wheels 12 and the second support wheel 13. According to the elasticity of the cloth, the tension range of the tension adjustment device is adjusted. If the elasticity of the cloth is large, the tension range of the tension adjustment device needs to be reduced; otherwise, the tension range needs to be increased.

[0036] The rotating block 16 is rotated, and the rotating block 16 drives the screw rod 15 to rotate, and the screw rod 15 drives the adjusting block 17 of the rod wall to move rightward, and the adjusting block 17 drives the U-shaped blocks 18 of the two side walls to pull the adjusting plate 19, so that the two moving blocks 11 move in a direction close to each other. At this time, the tension range is relatively large, which is suitable for fabrics with less elasticity;

[0037] On the contrary, the rotating block 16 is rotated in the opposite direction, and the two moving blocks 11 move to the opposite side to squeeze the first spring 7 and the second spring 10, so that the deformation range of the first spring 7 and the second spring 10 is relatively small. At this time, the tension range is relatively small, which is suitable for fabrics with greater elasticity.
