Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] To further understand the content of the present invention, the present invention will be described in detail in conjunction with the accompanying drawings.

[0028] Combined with Figures 1 - 8 , a film slitting device convenient for adjustment of the present invention includes a workbench 1. A support frame 101 is fixed on the top of the workbench 1. Two hydraulic rods 3 are fixed on the top of the support frame 101. A moving assembly 2 is fixed between the two hydraulic rods 3. A plurality of slitting knives 4 are connected to the components of the moving assembly 2. A feeding roll 6 and a rewinding roll 7 are respectively installed at the front and rear ends of the workbench 1. The moving assembly 2 includes a fixed plate 201 fixed between the two hydraulic rods 3. A moving plate 202 slides in the inner slideway of the fixed plate 201. A plurality of inclined slideways are formed on the moving plate 202. An adjusting rod 401 slides on each slideway. The adjusting rod 401 is fixed on one side of the slitting knife 4. The slitting knife 4 slides on the limit rod 206 inside the fixed plate 201 and is connected with a blade 402 at the bottom. The fixed plate 201 and the moving plate 202 are connected with a driving component.

[0029] Specifically, when this case is in use, the hydraulic rod 3 is started, and the whole moving component 2 is controlled to move up and down to a suitable position and then stop moving. The driving component is used to control the moving plate 202 to move in the inner slideway of the fixed plate 201. At this time, the adjusting rod 401 slides in the slideway of the moving plate 202, and the cutting knife 4 moves and slides on the limiting rod 206. When adjusted to a suitable distance, the driving can be stopped. Then, the rotating roller 5 on the mounting frame 102 is started to rotate, driving the film on the feeding roll 6 to be cut by the blade 402 and then wound on the receiving roll 7. This device has strong adjustment ability and good linkage, and has the advantages of high precision and high stability. It can conveniently adjust the distance and height of the cutting knife to meet the cutting requirements of protective film rolls of different sizes and specifications.

[0030] The following further describes the present utility model in conjunction with embodiments.

[0031] Embodiment 1:

[0032] Combined with Figures 4 - 8 , the driving component includes a moving block 203 fixed at the rear side of the moving plate 202. The moving block 203 slides in the opening of the fixed plate 201. A screw rod 204 is threadedly connected to the moving block 203. The screw rod 204 is rotatably connected to a fixed seat 2011 on one side of the fixed plate 201. A rotating handle 2041 is fixed at the top of the screw rod 204. The rotating handle 2041 is designed with anti-slip. When in use, the screw rod 204 on the fixed seat 2011 on one side of the fixed plate 201 is rotated, and the moving block 203 moves accordingly, driving the moving plate 202 to move. Fixing the rotating handle 2041 at the top of the screw rod 204 can improve the operation convenience, and the anti-slip design also improves the operation safety.

[0033] The blade 402 is fixed at the bottom of the cutting knife 4 with screws. The blade 402 is made of cemented carbide. The blade 402 is fixed at the bottom of the cutting knife 4 with screws. When the blade 402 needs to be replaced or maintained, it can be partially disassembled without overall disassembly, which is convenient for replacement and maintenance, saves maintenance time and efficiency. Cemented carbide has higher hardness, better wear resistance, and excellent thermal shock resistance, and can maintain long-term stability. It is commonly used in occasions with high requirements for cutting precision and efficiency.

[0034] Three balls 2021 are evenly distributed on both sides of the moving plate 202. The balls 2021 roll in the ball grooves of the moving plate 202. A chute 2012 is opened in the inner slideway of the fixed plate 201. The protruding parts of the balls 2021 roll in the chute 2012. Designing the balls 2021 on one side of the moving plate 202 to roll in the chute 2012 can effectively reduce the friction between components, thereby extending the service life of the components, improving the smoothness and precision of movement, and reducing the external force required during movement.

[0035] There are two upper and lower limit rods 206 fixed between the side plates of the fixed plate 201. Both of the two limit rods 206 pass through the slitting knife 4. Fixing the two limit rods 206 up and down can increase the limiting effect and improve the stability of the device, making the slitting knife 4 more stable during the moving process.

[0036] There is a measuring scale 205 fixed at the rear side of the fixed plate 201. There is a measuring rod 2031 fixed on one side of the moving block 203 close to the measuring scale 205. Fixing the measuring scale 205 at the rear side of the fixed plate 201 and matching the measuring rod 2031 on the moving block 203 can accurately control the rotation distance, adjust the spacing of the slitting knife 4, and thus complete the slitting more accurately, improving the slitting accuracy.

[0037] Embodiment 2:

[0038] Combined with Figures 2 - 3 , there is a material transporting movable roller group 1011 respectively arranged on both sides of the support frame 101. Adding a group of material transporting movable roller groups 1011 on the front and rear sides of the support frame 101 where the blade 402 is located can increase the transportation stability, help reduce the slitting error caused by too far fixed distance of the material, and improve the slitting accuracy and slitting efficiency.

[0039] A group of mounting brackets 102 are respectively fixed at the front and rear ends of the workbench 1. Rotating rollers 5 are installed on the two mounting brackets 102. A feeding roll 6 and a winding roll 7 are respectively sleeved on the two rotating rollers 5. A turntable 1021 is rotatably connected to the two mounting brackets 102. A spring 1022 is fixed inside one turntable 1021. The feeding roll 6 and the winding roll 7 are sleeved and fixed on the rotating roller 5. One end of the rotating roller 5 is placed into the hole of the turntable 1021 with the spring 1022, and is squeezed inward until the other end of the rotating roller 5 enters the turntable 1021 and then released. The spring 1022 pops out outward to fix the rotating roller 5 between the two turntables 1021. The installation and disassembly are simple and firm, making the disassembly and replacement convenient, saving the replacement time, and thus improving the production efficiency. It should be noted that the fixed connection method between the rotating roller 5 and the turntable 1021 is a prior art means and will not be elaborated here.
