[0023] An adjustable protective film roll slitting device comprises a frame 1, a cutting device 2 is arranged on the frame 1, a winding device 5 is arranged on the top of the frame 1, the cutting device 2 comprises a first motor 21, the output shaft of the first motor 21 is fixedly connected to a rotating rod 22, the rotating rod 22 is connected to a first rotating disk 23, the first rotating disk 23 is provided with two groups of slitting knives 24 with different densities, and further comprises:

[0024] The winding device 5 comprises a second motor 51, the output shaft of the second motor 51 is fixedly connected to a rotating rod, the end of the rotating rod is connected to a second rotating disk 52, and one end of the second rotating disk 52 is respectively provided with two sets of receiving rods 53 of different thicknesses;

[0025] Among them, the first motor 21 drives the first turntable 23 to rotate, and two groups of slitting knives 24 with different densities adjust their positions through the first turntable 23. Slitting knives 24 with different densities are used according to different needs. The second motor 51 drives the second turntable 52 to rotate, and two groups of material collecting rods 53 with different thicknesses adjust their positions through the second turntable 52. Material collecting rods 53 with different thicknesses are used according to different needs.

[0026] The first turntable 23 is connected to the slitting knife 24 by bolts, and the second turntable 52 is connected to the receiving rod 53 by bolts. Bolt connection is a simple and reliable connection method, which allows the operator to easily install or remove the slitting knife 24 and the receiving rod 53. This design enables the replacement of knives and receiving rods of different specifications or wear to be completed quickly, reducing downtime and maintenance costs.

[0027] The top of the frame 1 is connected to a rotating rod 22 near the groove, and the bottom of the other end of the frame 1 is connected to a rotating rod. This design rationally utilizes the space of the frame 1, so that the cutting device 2 and the winding device 5 can be compactly installed on the frame, which helps to reduce the overall footprint of the equipment and improve the space utilization rate of the workshop.

[0028] A fixing device 3 is provided next to the cutting device 2. The fixing device 3 includes a cylinder 31. The piston of the cylinder 31 is connected to a connecting block 32. The connecting block 32 is fixedly connected to a fixing rod 4. Through precise control of the cylinder 31, the fixing rod 4 can be ensured to stably fix the protective film roll or the material to be cut. This stable fixation reduces the movement and deformation of the material during the cutting process, thereby improving the cutting accuracy and consistency.

[0029] Grooves are respectively provided on the two side walls of the frame 1, and universal wheels 6 are connected to the four corners of the bottom end of the frame 1. Slide grooves are provided on both sides of the frame 1 near the fixing device 3. The grooves are used to place protective mold rolls. The slide grooves enable the fixing device 3 to move up and down freely. The design of the universal wheels 6 enables the equipment to adapt to different working environments and ground conditions.

[0030] The cylinder 31 is connected to the frame 1 by bolts, and the bolt connection is convenient for installation and disassembly, which makes the replacement, maintenance or adjustment of the cylinder 31 more convenient and quick. When maintenance or upgrading of the equipment is required, the operator can easily remove the bolts, remove the cylinder from the frame, and then perform necessary operations.

[0031] Working principle:

[0032] When the utility model is used, the protective film roll to be cut is placed on the groove of the frame 1, and the output shaft of the first motor 21 starts to rotate, driving the rotating rod 22 and the first rotating disk 23 connected thereto to rotate synchronously. The first rotating disk 23 is provided with two sets of slitting knives 24 with different densities. Through the rotation and adjustment mechanism, the operator can select and fix the required slitting knives 24 to the appropriate position. Once the position of the slitting knives 24 is determined and fixed, the protective film roll starts to pass through the cutting area. During the cutting process, the cylinder 31 of the fixing device 3 stabilizes the protective film roll through the connecting block 32 and the fixing rod 4. The cut protective film is fixed to the winding device 5, and the second motor 51 is started to drive the rotating rod and the second turntable 52 connected thereto to rotate. The second turntable 52 is provided with two groups of receiving rods 53 of different thicknesses. Similarly, through the rotation and adjustment mechanism, the operator can select the appropriate receiving rod 53 to adapt to protective films of different sizes or thicknesses. The receiving rod 53 tightly winds up the cut protective film to form a neat roll-shaped product. When a roll of protective film is cut and wound, the operator can turn off the motor and stop the equipment.
