Description

Technical Field

[0001] This utility model relates to the field of polishing devices, specifically to cutting equipment for release films. Background Technology

[0002] Release film is a thin film that can be adhered to the surface of an object and has a certain degree of adhesion or slight adhesion. In order to cut the release film according to customer needs, the following problems occur during the cutting process; Firstly, release film has a higher hardness than ordinary film. If the cutting speed is too fast, it is very easy to break in a jagged shape. On the other hand, slowing down the cutting speed is not conducive to improving production efficiency. At the same time, release film is usually cut from one edge to the other, with a long cutting span. The worktable needs to leave enough sliding distance and anti-deviation distance, which brings great difficulties in design. Therefore, special optimization is needed for the cutting process to meet the cutting requirements of release film.

[0003] To address this issue, those skilled in the art have designed a cutting device for release films. Utility Model Content

[0004] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a cutting device for release film.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: it includes a dust-collecting kit and a cutting component. The cutting component is located below the dust-collecting kit. The cutting component performs cutting by penetrating the release film and sliding laterally perpendicular to the movement direction of the release film. During cutting, the dust-collecting kit quickly absorbs and discharges the cut debris. The dust-collecting kit is equipped with a grinding wheel for grinding the cutting blades inside the cutting component.

[0006] Preferably, the vacuuming kit includes a dust collection frame and fan blades, with the fan blades located inside the dust collection frame. The fan blades are exhaust fans that draw air upwards to maintain continuous suction on the cutting components below.

[0007] Preferably, the cutting assembly includes a handle, a blade head, and a slide frame. The handle is slidably connected to the inside of the slide frame, and the blade head for cutting is connected to the upper end of the handle. A lifting hydraulic rod is provided at the bottom of the slide frame. The lifting hydraulic rod drives the entire cutting assembly to move upward, and the blade head cuts the release film upward to perform segmented and rapid cutting of the film.

[0008] Preferably, the cutting assembly further includes a push rod located on one side of the slide frame and a spring located on the other side of the slide frame. The push rod pushes the knife handle to slide laterally relative to the slide frame and compresses the spring. The push rod can drive the knife handle and the knife head to slide laterally, quickly cutting and segmenting the release film. By inserting the knife head and then making lateral cuts, the overall cutting time is shortened.

[0009] Preferably, grooves are provided on both the front and rear sides of the handle, and the grooves are slidably connected with the grinding wheel. The grooves are designed to avoid the grinding wheel and keep the grinding wheel in close contact with the blade.

[0010] Preferably, the grinding wheels are distributed on the left and right sides of the blade head, and when the handle slides laterally, the blade head contacts the grinding wheels. When the handle slides laterally, the bottom of the blade head will make a lateral cut on the release film, while the top of the blade head will contact the grinding wheels. With the help of the dust collection kit, not only can the fragments from cutting and the particles from grinding be quickly absorbed and discharged, but the blade head can also be cooled.

[0011] Preferably, the vacuuming kit has conveying rollers at both ends for conveying the release film, and a suction base at the rear end of the vacuuming kit. The suction base has a suction port on its surface and is connected to a vacuum pump. The suction base can adsorb the cut release film to prevent it from falling off, and slide laterally under the action of the conveying rollers.

[0012] Preferably, the bottom of the dust collection frame is connected to a base plate, and the surface of the base plate is provided with a sliding opening and an air intake. The sliding opening is slidably connected to the blade head. The negative pressure inside the dust collection frame can adsorb the release film through the air intake. The base plate is used to fit against the blade handle, which can prevent the blade handle from rising further. At the same time, the blade head can slide laterally along the sliding opening, and the air intake can use the small suction force of the dust collection kit to maintain the adsorption effect on the release film. Furthermore, due to the low suction force, the front conveying roller can still push the rear end of the cut release film forward in parallel.

[0013] The beneficial effects of this utility model are as follows: Based on the hardness characteristics of the release film, a method is designed to use a blade to poke open the release film from bottom to top, and then to cut the release film by sliding the blade horizontally. In addition, a dust collection kit is designed to quickly absorb any tiny debris that may appear during the cutting process. The method of cutting in small units within a small area and then connecting the small cuts together reduces blade wear during the cutting process and also reduces the wobbling problem that may occur when the blade cuts the hard release film, thus ensuring the integrity of the film edge after cutting. Furthermore, when the tool shifts left or right, the grinding wheel can be used to grind the tool, and the dust collection kit can quickly absorb the grinding debris, which can also have a cooling effect.

[0026] Example 1: This utility model provides a cutting device for release film, such as... Figure 1-6 As shown, the device includes a vacuuming kit 1 and a cutting component 3. The cutting component 3 is located below the vacuuming kit 1. The cutting component 3 performs cutting by penetrating the release film and sliding laterally perpendicular to the direction of movement of the release film. During cutting, the vacuuming kit 1 quickly absorbs and discharges the cut debris. The vacuuming kit 1 is equipped with a grinding wheel 2 for grinding the cutting blades inside the cutting component 3. The vacuuming kit 1 includes a dust collection frame 101 and a fan blade 102. The fan blade 102 is located inside the dust collection frame 101. The fan blade 102 is an exhaust fan that draws air upward to create a negative pressure inside the entire dust collection frame 101, maintaining continuous suction on the cutting component 3 below.

[0027] The cutting assembly 3 includes a handle 301, a cutter head 302, and a slide frame 305. The handle 301 is slidably connected to the inner side of the slide frame 305, and the cutter head 302 for cutting is connected to the upper end of the handle 301. A lifting hydraulic rod is provided at the bottom of the slide frame 305. The lifting hydraulic rod drives the entire cutting assembly 3 to move upward, causing the cutter head 302 to pierce the release film upward, and to perform segmented and rapid cutting of the film. Multiple cutters 302 are provided, and each cutter head is responsible for a segment of the cutting path, so that the wear of all cutters is quickly distributed.

[0028] The cutting assembly 3 also includes a push rod 303 located on one side of the slide frame 305 and a spring 304 located on the other side of the slide frame 305. The push rod 303 pushes the knife handle 301 to slide laterally relative to the slide frame 305 and squeezes the spring 304. The push rod 303 can drive the knife handle 301 and the knife head 302 to slide laterally, quickly cutting and dividing the release film. By inserting the knife head 302 and then making a lateral cut, the overall cutting time is shortened.

[0029] The handle 301 has grooves 3011 on both the front and rear sides, and the grooves 3011 are slidably connected to the grinding wheel 2. The grooves 3011 are designed to avoid the grinding wheel 2 and keep the grinding wheel 2 in contact with the blade head 302.

[0030] The grinding wheels 2 are distributed on the left and right sides of the blade head 302. When the handle 301 slides laterally, the blade head 302 contacts the grinding wheels 2. When the handle 301 slides laterally, the bottom of the blade head 302 will make a lateral cut on the release film, while the top of the blade head 302 will contact the grinding wheels 2. With the help of the dust collection kit 1, not only can the fragments during cutting and the particles during grinding be quickly absorbed and discharged, but the blade head 302 can also be cooled.

[0031] The vacuuming kit 1 has conveying rollers at both ends for conveying the release film. The vacuuming kit 1 has a suction base 4 at the rear end. The suction base 4 has a suction port on its surface and is connected to a vacuum pump. The suction base 4 can adsorb the cut release film to prevent it from falling off, and slide laterally under the action of the conveying rollers.

[0032] The bottom of the dust collection frame 101 is connected to a base plate 5, and the surface of the base plate 5 is provided with a sliding opening 501 and an air intake 502. The sliding opening 501 and the cutter head 302 are slidably connected. The negative pressure inside the dust collection frame 101 can adsorb the release film through the air intake 502. The base plate 5 is used to fit against the cutter handle 301, which can prevent the cutter handle 301 from rising further. At the same time, the cutter head 302 can slide laterally along the sliding opening 501, and the air intake 502 can use the small suction of the dust collection kit 1 to maintain the adsorption effect on the release film. Furthermore, due to the low suction, the front conveying roller can still push the rear end of the cut release film forward in parallel.

[0033] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
