[0027] In this embodiment, the positioning structure 3 serves to assist the tensioning of the tensioning structure 2, which is mainly achieved by holding the extension tube 304, aligning the connecting tube 303 on one side of its outer surface with the tensioning module 205, and rotating it, so that the second thread layer 302 and the first thread layer 301 on the outer surface of the connecting tube 303 are threadedly connected, and the tensioning module 205 is tightened by the action of the connecting tube 303, and the sliding rod 306 is partially inserted into the interior of the extension tube 304 to make the sliding rod 306 and the sliding ball 305 slidably connected, and the sliding rod 306 and the sliding ball 305, as well as the receiving block 307 and the extension support rod, play a supporting effect on one end of the cloth limiting roller body 1.

[0028] Working principle:

[0029] As shown in the figure, in actual use, the main body of the cloth limiting roller body 1 mainly plays the role of receiving and positioning the cloth tube, as well as the role of discharging and collecting materials. The main body of the cloth limiting roller body 1 is one of the indispensable devices in cloth production. The tensioning structure 2 arranged on the outer surface of the main body of the cloth limiting roller body 1 plays the role of tensioning and fixing the cloth tube. When tightening, the tensioning and positioning of the cloth tube needs to be completed with the assistance of the positioning structure 3, and the positioning structure 3 mainly plays the role of assisting the tensioning structure 2 in tensioning and fixing, and plays the role of supporting the other end of the main body of the cloth limiting roller body 1;

[0030] It should be noted that when it is necessary to position and fix the cloth drum, it is mainly completed through the cooperation of the tensioning structure 2 and the positioning structure 3. The hole of the cloth drum is sleeved from one end of the cloth limiting roller body 1 to the outer surface of the cloth limiting roller body 1, and the extension tube 304 is held, and the connecting tube 303 on one side is aligned with the multiple tensioning modules 205 and inserted and rotated, so that the second thread layer 302 and the first thread layer 301 on the outer surface of the connecting tube 303 are connected by threads. When connected, the tensioning module 205 will extend outward and present an open form, so as to achieve a tensioning effect. The tensioning effect will squeeze the hole of the cloth drum and achieve a tensioning, positioning and fixing effect. When the connecting tube 303 is connected through the second thread layer 302 and the first thread layer 301, the tensioning module 205 will be slidably connected with the fixing block 204 through the edge of its outer surface. Secondly, it should be noted that after the tensioning installation of the cloth drum is completed, it can be moved by holding the telescopic support rod 308 The sliding rod 306 is partially inserted into the interior of the extension tube 304, and the sliding rod 306 is fitted and connected with the sliding ball 305. When the cloth limiting roller body 1 is working, the sliding ball 305 is slidably connected with the sliding rod 306, and the sliding rod 306 and the sliding ball 305 as well as the receiving block 307 and the telescopic support rod 308 can play the effect of supporting one end of the cloth limiting roller body 1, and the limiting sleeve 201 part located in the tensioning structure 2 has a detachable effect, which is mainly achieved by manually pulling the limiting sleeve 201 to make the docking rod 202 inside the limiting sleeve 201 detach from the docking hole 203. After disassembly, the tensioning module 205 will not be affected by the limiting sleeve 201, and the tensioning module 205 can be moved and adjusted around the connection between the fixing block 204 and the tensioning module 205 due to its sliding connection with the fixing block 204, so that the cleaning effect can be achieved. The disassembly of the cloth cylinder is completed by the reverse operation of the installation of the above-mentioned cloth cylinder.
