[0028] When the device is in use, after the film 9 passes through the upper roller 10 and the lower roller 12, under the action of the spring 14, the spring 14 drives the rotating ring 13 to move, thereby causing the lower roller 12 to rise, and the upper roller 10 and the lower roller 12 clamp the film 9. The film 9 first passes through the positioning roller 6 on the left and then through the tensioning roller 4 on the left. After the film 9 is turned by the tensioning roller 4 on the right, the end of the film 9 passes through the positioning roller 6 on the right and enters between the upper roller 10 and the lower roller 12. Turning the handwheel 83 drives the worm 81 to rotate, the worm 81 drives the worm gear 82 to rotate, the worm gear 82 drives the lead screw 21 to rotate, the lead screw 21 drives the lead screw sleeve 22 to rotate and move relative to the fixed block 1, and the lead screw sleeve 22 drives the tensioning roller bracket 3 and the tensioning roller 4 to move synchronously. Turning the knob 72 drives the threaded rod 71 to rotate, the threaded rod 71 drives the threaded sleeve 73 to rotate and move up and down in the vertical plate 5, and the threaded sleeve 73 drives the positioning roller 6 to move up and down synchronously. Thus, this set of devices keeps the film 9 in a tensioned state all the time.

[0035] In another embodiment, please refer to the attached instructions Figures 1-5 , as a further solution of the present invention, the tension roller 4 and the positioning roller 6 are both horizontally symmetrically arranged, and the upper roller 10 and the lower roller 12 are both horizontally symmetrically arranged.

[0036] Thus, under the action of multiple groups of roller shafts, the film 9 is kept taut.

[0037] In one embodiment, please refer to the attached instructions Figures 1-5 , as a further solution of the present invention, a rotating ring 13 is rotatably installed on the outer side of the lower roller 12. A spring 14 is fixedly installed at the bottom end of the rotating ring 13, and a spring positioning plate 15 is installed at the bottom end of the spring 14.

[0038] The spring 14 drives the rotating ring 13 to bounce upwards, so that the lower roller 12 is in contact with the upper roller 10, thereby clamping the film 9.

[0039] During use, after the film 9 passes through the upper roller 10 and the lower roller 12, under the action of the spring 14, the spring 14 drives the rotating ring 13 to move, thereby causing the lower roller 12 to rise. The upper roller 10 and the lower roller 12 clamp the film 9. The film 9 first passes through the positioning roller 6 on the left and then through the tension roller 4 on the left. After the film 9 is turned by the tension roller 4 on the right, the end of the film 9 passes through the positioning roller 6 on the right and enters between the upper roller 10 and the lower roller 12. Rotate the handwheel 83 to drive the worm 81 to rotate. The worm 81 drives the worm wheel 82 to rotate, and the worm wheel 82 drives the lead screw 21 to rotate. The lead screw 21 drives the lead screw sleeve 22 to rotate and move relatively in the fixed block 1. The lead screw sleeve 22 drives the tension roller bracket 3 and the tension roller 4 to move synchronously. Rotate the knob 72 to drive the threaded rod 71 to rotate. The threaded rod 71 drives the threaded sleeve 73 to rotate and move up and down in the vertical plate 5. The threaded sleeve 73 drives the positioning roller 6 to move up and down synchronously. Thus, this set of devices keeps the film 9 always in a taut state.

[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
