[0028] When using the utility model, the film material to be rolled is generally in a roll. If the center hole is consistent with the size of the material roller 202, it can be used directly. When the center hole is too large, the hydraulic rod 206 is moved to make the adjusting roller 204 descend, and the film roll is put on the material roller 202 and the adjusting roller 203. The adjusting roller 204 is driven to rise by the output end of the hydraulic rod 206, and the spacing between the material roller 202 and the adjusting roller 203 is adjusted until it is appropriate. The servo motor 106 drives the winding roller 107 to rotate, so that the plastic film moves.

[0029] Example 2

[0030] Please refer to Figure 1 , Figure 4 and Figure 5 As shown, the tension control mechanism 3 includes a slot 301, which is opened at an upper position on one side where the two groups of first mounting plates 104 are close to each other, and a base 302 is fixedly connected to the inner bottom end of the slot 301, and a first sliding rod 303 is fixedly connected to the top of the base 302, and a sliding sleeve 304 is slidingly connected to the surface of the first sliding rod 303, and a second tension roller 307 is fixedly connected to the upper position of the surface of the sliding sleeve 304, and a first tension roller 306, a third tension roller 308 and several groups of auxiliary rollers 309 are also fixedly connected to one side where the two groups of first mounting plates 104 are close to each other, and the surfaces of the first tension roller 306, the second tension roller 307, the third tension roller 308 and several groups of auxiliary rollers 309 are all rotatably connected to rotating rollers, and a spring 305 is also fixedly connected between the base 302 and the sliding sleeve 304.

[0031] When using the utility model, when it is necessary to control the tension thereof to avoid wrinkles due to looseness or tearing due to over-tightening, the elastic force of the spring 305 drives the sliding sleeve 304 to move up and down, causing the third tension roller 308 to move up and down, thereby automatically adjusting the tension of the film.

[0032] Further in this embodiment, please refer to Figure 2 and Figure 6 As shown, the cutting mechanism 4 includes a second sliding rod 401, both ends of which are fixedly connected to the surface of one side of the inner part of the workbench 109 close to each other, and the surface of the second sliding rod 401 is slidably connected to a sliding block 402, and a cutter head 403 is clamped at the bottom of the sliding block 402.

[0033] When cutting is required, the film can be cut by pushing the sliding block 402 to slide on the second sliding rod 401 to drive the cutter head 403 to move.

[0034] Working principle and use process of the utility model: When the utility model is used, the film material to be rolled is generally rolled. If the center hole is consistent with the size of the material roller 202, it can be used directly. When the center hole is too large, the hydraulic rod 206 is moved to make the adjusting roller 204 descend, and the film roll is put on the material roller 202 and the adjusting roller 203, and the adjusting roller 204 is driven to rise by the output end of the hydraulic rod 206, and the spacing between the material roller 202 and the adjusting roller 203 is adjusted until it is suitable, and then the servo motor 106 drives the winding roller 107 to rotate to make the plastic film move. When it is necessary to control the tension thereof to avoid wrinkles caused by relaxation or tearing caused by excessive tightening, the elastic force of the spring 305 is used to drive the sliding sleeve 304 to move up and down, so that the third tension roller 308 moves up and down, thereby automatically adjusting the tension of the film. When cutting is required, the film can be cut by pushing the sliding block 402 to slide on the second sliding rod 401 to drive the knife head 403 to move. The above disclosure is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
