Description

Technical Field

[0001] This utility model relates to the technical field of paint protection film cutting devices, specifically a cutting device for self-healing paint protection film. Background Technology

[0002] Self-healing paint protection film is a type of paint protection film. It is a car protection film made of special materials and coating technology. It can automatically restore the surface smoothness after minor damage, continuously protect the paint and maintain its appearance. The self-healing paint protection film cutting device is a device used for segmented cutting of paint protection film.

[0003] Existing paint protection film cutting devices, such as the cutting device for producing automotive paint protection film disclosed in publication number CN222096214U, have the advantages of making the automotive paint protection film taut and applying force evenly to fix the protective film through leveling rollers and pressure grooves. However, the cutting blade of this cutting device cuts vertically downwards, and the two sides of the cut part of the paint protection film do not have a fixing structure, which makes it easy for deformation to occur on both sides of the cut part during the cutting process. Therefore, we propose a self-healing paint protection film cutting device. Utility Model Content

[0026] Example 1:

[0027] Combination Figure 1-5As shown, the present invention provides a cutting device for a self-healing paint protection film, comprising: a cutting device body 100 and a smoothing component 200; the cutting device body 100 includes a worktable 101 in the middle, a cutter 102 fixedly installed in the worktable 101, a cutting opening 103 provided in the cutter 102, a cutting blade 104 installed in the cutting opening 103, a conveying roller 105 fixedly installed on one side of the worktable 101, and a [missing information - likely a component or component] fixedly installed on one side of the worktable 101. The feeder 106 and the measuring tape 107 are fixedly installed on one side of the workbench 101; the smoothing assembly 200 includes a mounting bracket 201 movably installed on the outer side of the workbench 101, an electric slide rail 202 fixedly installed on one side of the mounting bracket 201, a fixed smoothing roller 203 and a movable smoothing roller 204 movably installed on both sides of the upper part of the workbench 101, a clamping bar 205 movably installed on the upper part of the cutter 102, and a fixed mounting at the center of the fixed smoothing roller 203 and the movable smoothing roller 204. The T-shaped rod 206 and the binding sleeve 207 are movably installed at the outer end of the T-shaped rod 206. A spring 208 is fixedly installed between the top of the T-shaped rod 206 and the binding sleeve 207. A fixed connecting rod 209 is also fixedly installed between the mounting bracket 201 and the binding sleeve 207 on the upper part of the fixed smoothing roller 203. A slider 210 is also movably installed on the electric slide rail 202. A movable connecting rod 211 is also fixedly installed between the slider 210 and the binding sleeve 207 on the upper part of the movable smoothing roller 204. The mounting bracket 201 is also fixedly mounted on both sides of the bottom with a first electric push rod 212, and the first electric push rod 212 is fixed to the outer end of the worktable 101. The clamping strip 205 is also provided with a knife groove 213 in the middle, and the width of the knife groove 213 is the same as the width of the cutting opening 103. The clamping strip 205 is also fixedly mounted with a fixing plate 214 on the top. The fixing plate 214 is also fixedly mounted with a second electric push rod 215 on the bottom, and the second electric push rod 215 is fixed to the outer end of the worktable 101.

[0028] Specifically, self-healing paint protection film is a type of paint protection film. It is an automotive protective film made of special materials and coating technology that can automatically restore the surface smoothness after minor damage, continuously protecting the paint and maintaining its appearance. The self-healing paint protection film cutting device is used for segmented cutting of the paint protection film. The paint protection film fed by the feeder 106 on the worktable 101 in the main body 100 of this cutting device can be pressed by the fixed smoothing roller 203 and the movable smoothing roller 204 on the mounting frame 201 before being cut by the cutter 102. The movable smoothing roller 204, driven by the electric slide rail 202, evenly smooths the paint protection film on the upper end of the worktables 101 on both sides of the cutter 102, thereby ensuring the overall flatness of the paint protection film on the upper end of the cutter 102 and improving the cutting stability of the paint protection film. Furthermore, the springs 208 installed between the T-shaped rods 206 and the restraining sleeves 207 on the fixed smoothing roller 203 and the movable smoothing roller 204 allow the fixed smoothing roller 203 and the movable smoothing roller 204 to be used for smoothing paint protection films of different thicknesses during cutting. After the smoothing rollers 203 and 204 smooth the paint protection film at both ends of the upper part of the cutter 102, the clamping strip 205 at the top of the cutter 102 can also be pressed against both ends of the cutting opening 103 under the drive of the second electric push rod 215, thereby strengthening the stability of the paint protection film cutting part on the cutting opening 103 during cutting, so as to improve the cutting flatness and cutting effect. The electric slide rail 202 installed on the mounting bracket 201 is mainly used for the movement of the smoothing rollers 204 to smooth the paint protection film on the worktable 101. Rod 209 is mainly used for connecting the fixed smoothing roller 203 and the mounting frame 201. Moving connecting rod 211 is mainly used for connecting the moving smoothing roller 204 and the slider 210. First electric push rod 212 is mainly used for driving the mounting frame 201 so that the fixed smoothing roller 203 and the moving smoothing roller 204 at its upper end can be moved down to the upper end of the worktable 101. The knife groove 213 provided in the pressing bar 205 is mainly used to prevent the cutting knife 104 from being blocked during movement. Second electric push rod 215 is mainly used for lifting and lowering the pressing bar 205.

[0029] Working principle and usage process of this utility model:

[0030] When cutting the self-healing paint protection film, the paint protection film roll is first fed onto the upper end of the worktable 101 by the feeder 106. After the paint protection film is on the upper end of the worktable 101, the first electric push rod 212 is activated to move the mounting bracket 201 downward, so that the fixed smoothing roller 203 and the movable smoothing roller 204 on the inner side of the mounting bracket 201 press down onto the paint protection film on the upper end of the worktable 101 outside the cutter 102. At this time, after the movable smoothing roller 204 on the slider 210 is moved by the electric slide rail 202, the movable smoothing roller 204 moves... The paint protection film is evenly smoothed after being fed onto the upper end of the cutter 102 and the upper end of the worktable 101. After the smoothing roller 204 completes the smoothing of the paint protection film, it stays and presses on the paint protection film. Then, the second electric push rod 215 is activated to drive the pressing strip 205 to move down and press the pressing strip 205 to both sides of the cutting opening 103 at the upper end of the cutter 102. This presses the smoothed paint protection film on both sides of the cutting area on the cutting opening 103 to ensure the stability and cutting effect of the paint protection film during cutting.

[0031] Although embodiments of the present invention have been shown and described, those skilled in the art will understand 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 claims and their equivalents.
