[0018] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Example: Please refer to Figure 1-2 A tension-adjustable PET strip cutting guide device includes a base plate 1 and a mounting frame 2. The mounting frame 2 is fixedly installed on the upper end of the base plate 1. A cutting structure is installed on one side of the upper end of the mounting frame 2, and an adjusting guide structure is installed on the other side of the mounting frame 2.

[0020] The adjusting guide structure includes: two drive frames 3, two motors 4, two lead screws 5, two moving blocks 6, an adjusting frame 7, several partitions 8, and several guide components;

[0021] Two drive frames 3 are respectively installed on the two side walls of one end of the mounting frame 2. Two motors 4 are respectively installed at the bottom of the two drive frames 3. The top ends of two lead screws 5 are respectively movably embedded in the upper wall of the two drive frames 3, and the bottom ends are respectively connected to the drive ends of the two motors 4. Two moving blocks 6 are respectively movably embedded in the two drive frames 3, and are respectively movably fitted on the upper ends of the two lead screws 5. The two ends of the adjusting frame 7 are respectively fixedly connected to the two moving blocks 6. Several guide components are respectively embedded between several partitions 8.

[0022] When slitting PET strips, the operator first moves the device to the designated position and supports it with the base plate 1. Then, the PET film is placed on the upper part of the designated equipment, and one end of the PET film is pulled out. It is then cut by the slitting structure at the upper end of the mounting frame 2. The cut PET strip is then passed through several guide components and connected to the designated winding equipment. The winding equipment then pulls one end of the PET strip, causing the PET film to be cut into multiple PET strips under the action of the slitting structure. This slitting operation is performed continuously. During the slitting process, two motors 4 located at the bottom of the two drive frames 3 work. Through the cooperation of the two motors 4 and two lead screws 5, the height of the two moving blocks 6 within the two drive frames 3 is adjusted. This adjusts the height of the adjustment frame 7 and several guide components, thereby achieving the purpose of synchronously adjusting the tension of multiple PET strips.

[0023] In the specific implementation process, several guiding components include: a guiding frame 9, two guiding rollers 10, a connecting frame 11, and multiple electric push rods 12;

[0024] The two ends of the guide frame 9 are respectively movably fitted onto one side of two partitions 8. The two ends of the guide rollers 10 are respectively movably installed on the inner side walls of the guide frame 9. The two ends of the connecting frame 11 are respectively connected to the lower side walls of the guide frame 9. The multi-segment electric push rods 12 are embedded in the lower wall of the adjusting frame 7, and the telescopic ends are connected to the bottom of the connecting frame 11.

[0025] When the tension of multiple PET bright strips is adjusted independently, the multi-segment electric push rod 12 at the lower end of the driving adjustment frame 7 is operated. The multi-segment electric push rod 12 cooperates with the connecting frame 11 to adjust the height of the guide frame 9 and the two guide rollers 10 between the partition plate 8, and the winding and cutting tension of a single PET bright strip is adjusted independently.

[0026] In the specific implementation process, the cutting structure includes: two fixed frames 13, an operation plate 14, and several cutting blades 15;

[0027] Two fixed frames 13 are respectively installed on the inner side walls of the mounting frame 2, and the two ends of the operating plate 14 are respectively movably embedded in the two fixed frames 13. Several cutting blades 15 are evenly installed on the upper end of the operating plate 14.

[0028] When slitting PET bright strips, the operating plate 14 is fixed in two fixed frames 13 with bolts, and several cutting blades 15 are fixed in place. The PET film is then slitted into multiple PET bright strips by the cutting blades 15.

[0029] In the specific implementation process, fixing bolts 16 are embedded in the upper wall of both fixed frames 13.

[0030] In the specific implementation process, the connection position between the moving block 6 and the lead screw 5 is machined with internal threads.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
