Description

Technical Field

[0001] The utility model belongs to the technical field of textile equipment and relates to a grinding device with stable tension. Background Art

[0002] At present, most of the sanding machines on the market do not control the tension of the cloth feeding. However, the change of tension often occurs in the cloth feeding stage. When feeding the cloth, the height, squeezing, pulling, etc. of the grey cloth stored in the cart will affect the change of tension. When the tension is large, the sanding intensity is large, and holes are easy to appear. When the tension is small, it is not easy to cause hair. The change of tension is easy to lead to unstable sanding quality.

[0003] For the above reasons, we need a device that can stably adjust the cloth feeding tension without increasing the difficulty and convenience of operation. Before the grey cloth enters the grinding roller, the tension is stable to reduce the occurrence of quality problems. Utility Model Content

[0004] The purpose of the utility model is to provide a sanding device with stable tension in view of the above problems existing in the prior art. The technical problem to be solved by the utility model is how to adjust the cloth tension of the sanding device.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a tension-stable sanding device, characterized in that it includes a first cloth guide roller, a second cloth guide roller, a plurality of sanding rollers and a tension adjustment mechanism, the tension adjustment mechanism includes a support fixed on a frame and a counterweight swing arm connected to the support, one end of the counterweight swing arm is rotatably connected to the support, and the other end of the counterweight swing arm is rotatably connected to an adjustment cloth guide roller; the adjustment cloth guide roller is located between the first cloth guide roller and the second cloth guide roller.

[0006] Furthermore, the counterweight swing arm is provided with a plurality of hanging holes along the length direction of the counterweight swing arm, and the tension adjustment mechanism also includes a counterweight block, and the counterweight block is fixed with a hook capable of hanging the counterweight block on the counterweight swing arm.

[0007] At present, the sanding machine simply relies on the traction of the cloth to drive the cloth to move, and there is no additional cloth tension control method. In this scheme, after the cloth is pulled from the first cloth guide roller, the cloth guide roller is adjusted, then the second cloth guide roller is passed, and finally the sanding roller is applied with traction force to the cloth behind the sanding roller. During the sanding process, the cloth tension changes caused by the shaking of the cloth caused by the hysteresis resistance of the sanding roller and the pulling of the piled cloth at the rear can be buffered and adjusted by the deadweight of the counterweight swing arm. In addition, the counterweight block can be mounted to adjust the cloth tension. The mounting position of the counterweight block on the counterweight swing arm is different, and the cloth tension is also different. The mounting position of the counterweight block can be adjusted according to needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 It is a structural schematic diagram of the present grinding device.

[0009] In the figure, 1. first cloth guide roller; 2. second cloth guide roller; 3. counterweight swing arm; 4. support; 5. adjusting cloth guide roller; 6. hanging hole; 7. counterweight block; 8. grinding roller. DETAILED DESCRIPTION

[0010] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0011] like Figure 1 The sanding device shown includes a first cloth guide roller 1, a second cloth guide roller 2, a plurality of sanding rollers 8 and a tension adjustment mechanism, the tension adjustment mechanism includes a support 4 fixed on a frame and a counterweight swing arm 3 connected to the support 4, one end of the counterweight swing arm 3 is rotatably connected to the support 4, and the other end of the counterweight swing arm 3 is rotatably connected to an adjusting cloth guide roller 5; the adjusting cloth guide roller 5 is located between the first cloth guide roller 1 and the second cloth guide roller 2.

[0012] The counterweight swing arm 3 is provided with a plurality of hanging holes 6 along the length direction of the counterweight swing arm 3 . The tension adjustment mechanism further comprises a counterweight block 7 , on which a hook is fixedly provided for hanging the counterweight block 7 on the counterweight swing arm 3 .

[0013] At present, the sanding machine simply relies on the traction of the cloth to drive the cloth to move, and there is no additional cloth tension control method. In this scheme, after the cloth is pulled from the first cloth guide roller 1, the cloth guide roller 5 is adjusted, and then the second cloth guide roller 2 is passed, and finally enters the sanding roller 8, and traction is applied to the cloth behind the sanding roller 8. During the sanding process, the cloth tension changes caused by the shaking of the cloth caused by the hysteresis resistance of the sanding roller 8 and the pulling of the pile of cloth at the rear can be buffered and adjusted by the deadweight of the counterweight swing arm 3. In addition, the counterweight block 7 can be mounted to adjust the tension of the cloth. The mounting position of the counterweight block 7 on the counterweight swing arm 3 is different, and the tension of the cloth is also different. The mounting position of the counterweight block 7 can be adjusted according to needs.

[0014] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
