On one side of the fixed frame, there are symmetrically distributed mounting frames, and the mounting frames are fixedly connected to the bottom plate. A wire guiding roller is rotatably connected inside the mounting frame. Between the two mounting frames, there are symmetrically distributed mounting plates. The bottom of the mounting plate is slidably connected to a fixed column fixedly connected to the bottom plate. A fixed roller is rotatably connected between the two mounting plates. A plurality of equally spaced grooves are formed on the outer wall of the fixed roller. Above the fixed roller, there is a connecting shaft rotatably connected to the mounting plate. A plurality of equally spaced slitting knives are installed on the outer wall of the connecting shaft, and part of the slitting knives extends into the grooves. A fixed sleeve is fixedly connected to one side of the slitting knife. Symmetrically distributed clamping rods are slidably connected to both sides of the fixed sleeve. A plurality of groups of equally spaced clamping grooves are formed on the outer walls of both sides of the connecting shaft, and the clamping grooves are adapted to the clamping rods. One side of the clamping rod is fixedly connected to a connecting rod. One end of the connecting rod extending out of the fixed sleeve is fixedly connected to a first movable rod. A second movable rod is fixedly connected to the top of the first movable rod. The outer wall of the second movable rod is slidably connected to a support plate fixedly connected to the fixed sleeve.

[0007] As a further scheme of the utility model: A spring sleeving the second movable rod is fixedly connected to the bottom of the support plate, and the other end of the spring is fixedly connected to the first movable rod.

[0008] As a further solution of the present utility model: the two sets of the first movable rods are symmetrically distributed about the center. A gear is rotatably connected to the side of the fixed sleeve away from the connecting shaft. The two sides of the gear are engaged with racks that are symmetrically distributed about the center, and the racks are fixedly connected to the first movable rods.

[0009] As a further solution of the present utility model: a cross plate fixedly connected to the mounting plate is provided below the fixed roller. A cylinder is fixedly connected to the top of the bottom plate, and the driving end of the cylinder is fixedly connected to the cross plate.

[0010] As a further solution of the present utility model: a second motor is fixedly connected to one of the mounting plates, and the output shaft of the second motor is fixedly connected to the connecting shaft.

[0012] The present utility model has the following beneficial effects:

[0013] 1. In the present utility model, during use, the plastic film moves through the guide roller, the fixed roller, another guide roller and the winding roller. The winding roller winds up the plastic film. Start the cylinder, and the driving end of the cylinder drives the cross plate to move, thereby driving the mounting plate and the fixed roller to move, so as to adjust the tension during transportation, and avoid the failure of cutting due to the material not being tightened on the surface of the fixed roller during transportation. Start the second motor, and the output shaft of the second motor rotates to drive the connecting shaft to rotate, thereby driving the cutting knife to rotate so that the cutting knife cuts the material.

[0014] 2. In the present utility model, during adjustment, pull the second movable rod, the second movable rod drives the first movable rod to move, thereby driving the rack to move. The movement of the rack causes the gear to rotate, so that the other first movable rod moves in the opposite direction. When pulling one of the second movable rods, the two first movable rods move simultaneously. The first movable rod drives the connecting rod and the clamping rod to move, so that the clamping rod disengages from the clamping groove, and then the fixed sleeve can be pushed to adjust the position of the cutting knife. After the adjustment is completed, release the second movable rod, and the spring causes the first movable rod to reset, so that the clamping rod enters the clamping groove to fix the cutting knife, which is convenient for adjustment.

The bottom of the mounting plate 7 is slidably connected to a fixed column 21 fixedly connected to the bottom plate 1. A fixed roller 10 is rotatably connected between the two groups of mounting plates 7. A plurality of equally spaced grooves 11 are formed on the outer wall of the fixed roller 10. Above the fixed roller 10, there is a connecting shaft 17 rotatably connected to the mounting plate 7. A plurality of equally spaced slitting knives 12 are mounted on the outer wall of the connecting shaft 17, and part of the slitting knives 12 extends into the grooves 11.

[0024] Working principle:

[0025] In this application, when in use, the plastic film moves through the wire guiding roller 6, the fixed roller 10, another wire guiding roller 6 and the winding roller 3. The winding roller 3 winds the plastic film. The cylinder 9 is started. The driving end of the cylinder 9 drives the cross plate 8 to move, thereby driving the mounting plate 7 and the fixed roller 10 to move, so as to adjust the tension during transportation and avoid the failure of slitting due to the material not being tightened on the surface of the fixed roller 10 during transportation. The second motor 25 is started. The output shaft of the second motor 25 rotates to drive the connecting shaft 17 to rotate, thereby driving the slitting knives 12 to rotate so that the slitting knives 12 slit the material;

[0026] In this application, during adjustment, the second movable rod 19 is pulled. The second movable rod 19 drives the first movable rod 15 to move, and then drives the rack 14 to move. The movement of the rack 14 causes the gear 13 to rotate, which in turn causes the other first movable rod 15 to move in the opposite direction. When one of the second movable rods 19 is pulled, the two first movable rods 15 move simultaneously. The first movable rod 15 drives the connecting rod 22 and the clamping rod 24 to move, so that the clamping rod 24 disengages from the clamping groove 23, and then the fixed sleeve 16 can be pushed to adjust the position of the slitting knife 12. After the adjustment is completed, the second movable rod 19 is released, and the spring 20 causes the first movable rod 15 to reset, so that the clamping rod 24 enters the clamping groove 23 to fix the slitting knife 12, which is convenient for adjustment.
