After the tension control roller 5 contacts the material, the tension (tightness) of the material can be adjusted. Compared with the existing ones, the utility model adjusts the tension (tightness) of the material to avoid loosening, wrinkling and breaking of the material, thereby improving the processing efficiency of the material;

[0040] Secondly, by providing two limiting rings 15, the material can be limited under the action of the two limiting rings 15 to avoid the material from being offset, thereby improving the processing accuracy of the material;

[0041] And by pulling the fixing rod 19, the compression spring 21 will perform a corresponding stretching movement. After one end of the fixing rod 19 is disengaged from the second clamping hole 18, the two limit rings 15 can be moved and the distance between the two limit rings 15 can be adjusted. Then the fixing rod 19 is released again. At this time, the fixing rod 19 will be driven to move under the action of the compression spring 21. After one end of the fixing rod 19 is clamped into the second clamping hole 18, the two limit rings 15 can be fixed. Therefore, the utility model can adjust the two limit rings 15 so that the two limit rings 15 can meet the use of materials of different widths, and the practicality is relatively high.
