[0028] In one embodiment of this utility model, such as Figure 1-3As shown, a self-adhesive film serrated slitting machine includes a base frame 1, a drive roller 2, a driven roller 3, a positioning component 4, a first drive device 5, a second drive device 6, a hinge seat 7, a serrated cutter, and an electrical control box 9. The drive roller 2 and the driven roller 3 are rotatably mounted on the base frame 1. The second drive device 6 drives the drive roller 2 to rotate. The positioning component 4 is movably mounted on the base frame 1 and is located between the drive roller 2 and the driven roller 3. The first drive device 5 drives the positioning component 4 to move left and right along the length of the base frame 1. The hinge seat 7 and the electrical control box 9 are respectively mounted on the base frame 1. The serrated cutter is oscillatingly mounted on the hinge seat 7. The electrical control box 9 is connected to the first drive device 5.In this embodiment, the first driving device 5 is specifically a ball screw linear module. Both the first driving device 5 and the saw blade cutting machine are commercially available. During installation, the driving roller 2 and the driven roller 3 are respectively mounted on the base frame 1, with the driving roller 2 located behind the driven roller 3. The second driving device 6 is mounted on the base frame 1, and its output end is connected to the end of the driving roller 2 to drive its rotation. The first driving device 5 is mounted on the base frame 1, located between the driving roller 2 and the driven roller 3, and is used to drive the positioning assembly. 4. Move left and right along the length of the base frame 1, that is, move left and right along the length of the drive roller 2 or driven roller 3. The hinge seat 7 and the electrical control box 8 are respectively installed on the rear side of the base frame 1. The hinge seat 7 is located on the right side of the electrical control box 9. The serrated blade cutting machine is hinged to the top of the hinge seat 7. The electrical control box 9 is connected to the first drive device 5, that is, the electrical control box 9 can control the position of the positioning component 4 through the first drive device 5. During operation, the length to be cut is input into the control panel of the electrical control box 9, for example, the input cutting data is two meters. The electrical control box 9 feeds back a signal to the first drive device 5. It should be noted that Before operation, the positioning component 4 needs to be calibrated, taking the cutting position of the serrated blade cutter as the origin. The first driving device 5 drives the positioning component 4 to move two meters to the left from the cutting position of the serrated blade cutter. After the positioning component 4 is in place, the entire roll of protective film to be cut is placed between the driving roller 2 and the driven roller 3. The protective film is specifically a self-adhesive film. The entire roll of protective film is supported by the driving roller 2 and the driven roller 3. The end of the entire roll of protective film abuts against the positioning component 4 to achieve the purpose of setting the cutting length of the protective film. After positioning, the second driving device 6 drives the driving roller 3 to rotate. The active roller 2 drives the protective film roll and the driven roller 3 to rotate. During the rotation, the handle of the serrated cutter is pulled, causing the serrated cutter to move downwards to cut the protective film roll, thereby cutting a two-meter-long protective film roll, thus achieving fixed-length cutting. This application uses a base frame 1, active roller 2, driven roller 3, positioning component 4, first drive device 5, second drive device 6, hinge seat 7, serrated cutter, and electrical control box 9. Data is input into the electrical control box 9 to move the positioning component 4 to a set position to determine the cutting length. This is convenient and quick, without the need for manual adjustment and measurement. Furthermore, during the cutting process, the protective film roll rotates while being cut, which helps to improve cutting efficiency and cutting quality.

[0029] like Figure 1-2As shown, the positioning component 4 includes a movable base 41, a support rod 42, and a rotating wheel 43; the movable base 41 is mounted on the first driving device 5, and the first driving device 5 is used to drive the movable base 41 to move left and right; one end of the support rod 42 is mounted on the top surface of the movable base 41; and the rotating wheel 43 is rotatably mounted on the top of the support rod 42. In this embodiment, the movable base 41 is specifically connected to the lead screw of the first driving device 5. During operation, the two sides of the protective film roll abut against the outer periphery of the active roller 2 and the driven roller 3, respectively. The outer periphery of the protective film roll's winding axis is placed on the top of the support rod 42, which provides support and ensures the stability of the protective film roll. The end of the protective film roll abuts against the outer periphery of the rotating wheel 43. After the protective film roll is placed, the second driving device 6 drives the active roller 2 to rotate. The rotating roller 2, in conjunction with the driven roller 3, causes the protective film roll to rotate, and the rotating wheel 43 at the end of the protective film roll also rotates synchronously. This not only prevents the end of the protective film roll from being damaged by friction but also improves the smoothness of the rotation of the protective film roll, which is beneficial for subsequent cutting.
