[0002] A cloth roll machine is a device used to roll materials such as cloth or paper into a roll. It usually consists of a group of rollers. The cloth or paper is rolled onto a reel or tube core through these rollers to form a curled shape for easy storage, transportation and subsequent processing. It is widely used in textile, printing and dyeing, clothing, packaging and other industries.

[0003] In the prior art, when the cloth is rolled up by a cloth rolling machine, in order to ensure the tension of the cloth and avoid the cloth from loosening, the cloth is usually pressed down by a tensioning roller to tighten the cloth. Since the tensioning roller cannot be adjusted well, the downward pressure on the cloth often maintains a constant tension, and different cloths have different elasticity, softness and other characteristics, which will affect the tension change of the cloth during transportation. Therefore, the cloth is prone to looseness or being stretched too tight during the rolling process, which can easily cause the cloth to wrinkle or break, affecting the quality and effect of the rolling. Therefore, in order to solve the above problems, a tension adjustment device for a cloth rolling machine is proposed. Utility Model Content

[0024] An adjusting mechanism is provided on the inner side of the support plate 11, and the adjusting mechanism includes a rotating rod 2, which is movably connected to the inner side of the support plate 11, a first conical tooth 21 is fixedly connected to the surface of the rotating rod 2, a motor 22 is fixedly installed on the surface of the support plate 11, a screw rod 24 is movably connected to the inner side of the support plate 11, a second conical tooth 25 is fixedly connected to the top of the screw rod 24, a connecting block 26 is threadedly connected to the surface of the screw rod 24, a connecting plate 27 is fixedly connected to the surface of the connecting block 26, and a fixing frame 29 is provided at the bottom end of the connecting plate 27. By driving the first conical tooth 21 to rotate through the rotating rod 2, the second conical tooth 25 can drive the screw rod 24 to rotate, and then the connecting block 26 can drive the connecting plate 27 and the fixing frame 29 to rise and fall, so as to facilitate the adjustment of the position of the tensioning roller 14, and then the tension of different fabrics can be adjusted, which can better avoid the fabric from breaking or loosening.

[0025] Furthermore, the adjustment mechanism also includes a movable groove 23, which is opened on the inner side of the support plate 11, and a limiting groove 28 is opened on the inner wall of the movable groove 23. Through the opening of the limiting groove 28, the connecting block 26 can be limited, and the connecting block 26 can be prevented from being offset under the action of the screw rod 24, so that the connecting block 26 can stably drive the connecting plate 27 to move.

[0026] Furthermore, the first conical teeth 21 are in two groups and fixedly connected to the rotating rod 2, the rotating rod 2 is fixedly connected to the output end of the motor 22, the connecting blocks 26 are in two groups and fixed to both ends of the connecting plate 27, the tensioning roller 14 and the fixed frame 29 are movably connected, and the movement of the connecting block 26 can drive the connecting plate 27 and the fixed frame 29 to rise and fall, and then the tensioning roller 14 can be moved up or down, so that the strength of the tensioning roller 14 pressing the cloth can be adjusted, which is convenient for adjusting the tension of the cloth.

[0027] Furthermore, the screw rod 24, the second conical teeth 25 and the connecting block 26 are all movable on the inner side of the movable groove 23, and the connecting block 26 and the limiting groove 28 are movably connected. Through the setting of the second conical teeth 25, when the first conical teeth 21 rotate under the action of the rotating rod 2, the second conical teeth 25 can be transmitted, and then the second conical teeth 25 can drive the screw rod 24 to rotate.

[0028] Furthermore, an auxiliary mechanism is provided on the surface of the connecting plate 27, and the auxiliary mechanism includes a fixed block 3, which is fixedly connected to the lower surface of the connecting plate 27, a fixed rod 31 is fixedly connected to the inner surface of the fixed block 3, a moving block 32 is movably connected to the surface of the fixed rod 31, a movable rod 33 is movably connected to the bottom end of the moving block 32, and a spring 34 is fixedly connected to the surface of the moving block 32.

[0029] Furthermore, one end of the movable rod 33 is movably connected to the movable block 32 via a rotating shaft, the other end of the movable rod 33 is movably connected to the fixed frame 29 via a rotating shaft, one end of the spring 34 is fixedly connected to the fixed block 3, and the other end of the spring 34 is fixedly connected to the movable block 32. Due to the elastic property of the spring 34, when the cloth is stretched too tight, the tensioning roller 14 is subjected to pressure, which can make the fixed frame 29 move vertically, and then the movable rod 33 moves and makes the movable block 32 move on the surface of the fixed rod 31, so that the tensioning roller 14 can adapt to the tightness of the cloth to a certain extent, which can reduce the breakage caused by excessive tightness of the cloth.

[0030] Working principle: When in use, the motor 22 is electrically connected to an external power source, and the staff starts the motor 22 by pressing a switch. The motor 22 drives the rotating rod 2 to rotate, and the first conical tooth 21 rotates under the action of the rotating rod 2, and then the second conical tooth 25 rotates under the action of the first conical tooth 21 and drives the screw 24 to rotate. The connecting block 26 is limited by the limiting groove 28 and moves inside the movable groove 23 under the action of the screw 24. The connecting plate 27 drives the fixed frame 29 to rise and fall under the action of the connecting block 26, so that the position of the tensioning roller 14 can be adjusted to achieve the effect of adjusting the tension of the cloth.

[0031] When the position of the tensioning roller 14 is adjusted, when the cloth is stretched too tight by the tensioning roller 14, the fixed frame 29 will be forced to move vertically upward, and then the movable rod 33 will move through the rotating shaft, and the movable block 32 will move on the surface of the fixed rod 31. At this time, the spring 34 will be deformed. When the cloth relaxes again, the movable block 32 can be reset under the rebound action of the spring 34, and then the movable rod 33 is reset to drive the fixed frame 29 and the tensioning roller 14 to move downward, so that the cloth is stretched tight, so that the tensioning roller 14 can adapt to the tension changes of the cloth to a certain extent.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and above.
