Abstract
Description
Technical Field
[0001] This utility model relates to the field of release film processing technology, specifically a PET release film slitting and rolling machine. Background Technology
[0002] PET release film is a functional film based on polyethylene terephthalate (PET). It possesses excellent physical properties, such as high transparency, high gloss, good mechanical strength, and dimensional stability. In terms of surface treatment, by coating it with release agents such as silicone oil, it achieves extremely low surface energy, allowing other materials to easily separate from it. Therefore, it is widely used in adhesive products, electronics, automotive, and optics fields, such as as a protective film for mobile phone screens and as a release material for self-adhesive labels, playing important roles in isolation, protection, and ease of processing. PET release film requires cutting into rolls during processing.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Please see Figure 1-4 This utility model provides a technical solution: a PET release film slitting and rolling machine, including a base 1, a bracket 3 fixedly connected to the top of the base 1, and a fourth motor 4 fixedly mounted on the side of the bracket 3. There are two fourth motors 4, rotating in opposite directions. A cleaning roller 401 is fixedly mounted on the output shaft of the fourth motor 4. The surface of the cleaning roller 401 can absorb dust. When the fourth motor 4 rotates, the cleaning roller 401 rotates. During use, the release film moves upward. Viewed from the right, the front cleaning roller 401 rotates clockwise, and the rear cleaning roller 401 rotates counterclockwise. The release film moves upward relative to the front and rear cleaning rollers 401. The cleaning roller 401 moves on its surface. A second motor 301 is fixedly installed inside the bracket 3. There are two second motors 301. A reciprocating screw 302 is fixedly installed on the output shaft of the second motor 301. When the second motor 301 rotates, the reciprocating screw 302 rotates. A moving block 304 is installed on the outside of the reciprocating screw 302. When the reciprocating screw 302 rotates, the moving block 304 moves back and forth. A third motor 305 is fixedly installed on the surface of the moving block 304. A brush 306 is fixedly installed on the output shaft of the third motor 305. When the third motor 305 rotates... The brush 306 rotates, and a mounting cover 307 is fixedly connected to the side of the moving block 304. The mounting cover 307 moves with the moving block 304. The output shaft of the third motor 305 is rotatably connected to the mounting cover 307. A tube 601 is fixedly mounted on the surface of the mounting cover 307. The release film passes between two cleaning rollers 401. The rotation of the cleaning rollers 401 removes dust from the surface of the release film. The moving block 304 moves left and right, and the third motor 305 and the brush 306 move accordingly. The brush 306 moves left and right relative to the cleaning rollers 401, and at the same time, the brush 306 rotates, which can move the cleaning rollers... Dust on the surface of 401 is brushed off and sucked away by tube 601. A support plate 101 is fixedly connected to the top of the base 1. A limit strip 5 is fixedly connected between the support plates 101. An installation strip 501 is fixedly connected to the front side of the support plate 101. A second telescopic rod 502 is fixedly installed in the middle of the installation strip 501. A blade 503 is fixedly installed on the output shaft of the second telescopic rod 502. When in use, the release film passes between the blade 503 and the limit strip 5. When it needs to be cut, the second telescopic rod 502 is activated, the blade 503 moves, and the blade 503 abuts against the limit strip 5, and the release film is cut.
[0022] Among them, a support rod 102 is fixedly connected to the side of the left support plate 101, and a first rotating seat 103 is rotatably connected to the end of the support rod 102. The first rotating seat 103 can rotate freely.
[0023] The right support plate 101 has a first telescopic rod 2 rotatably mounted in the middle. The output shaft of the upper first telescopic rod 2 is fixedly mounted with a first motor 201. The output shaft of the first motor 201 is fixedly mounted with a second rotating seat 202. The output shaft of the lower first telescopic rod 2 is rotatably connected to a third rotating seat 203. When one end of the take-up roller with release film is pressed against the lower first rotating seat 103, the lower first telescopic rod 2 is activated, and the third rotating seat 203 moves to install the take-up roller. At this time, the take-up roller can rotate freely. When one end of the empty take-up roller is pressed against the upper first rotating seat 103, the upper first telescopic rod 2 is activated, and the second rotating seat 202 moves to install the take-up roller. The first motor 201 rotates, causing the empty take-up roller to rotate. The take-up roller with release film releases the release film, and the empty take-up roller rolls up the release film.
[0024] Among them, a slide rod 303 is fixedly connected between the brackets 3. The slide rod 303 is slidably connected to the moving block 304. The function of the slide rod 303 is to prevent the moving block 304 from flipping when it moves.
[0025] The vacuum cleaner 6 is fixedly installed on the top of the base 1. The vacuum cleaner 6 is fixedly connected to the pipe 601, and the pipe 601 is fixedly connected to the moving block 304. The vacuum cleaner 6 generates negative pressure to suck away the dust. The vacuum cleaner 6 needs to be cleaned regularly. The moving block 304 provides support for the pipe 601.

[0027] The reciprocating screw 302 is rotatably connected to the bracket 3, and the bracket 3 supports the reciprocating screw 302.
[0028] In this design, the brush 306 is in contact with the cleaning roller 401, while the mounting cover 307 is not in contact with the cleaning roller 401. The brush 306 rotates to brush off the dust on the surface of the cleaning roller 401, and the mounting cover 307 supports the tube 601.
[0029] Working principle: During use, a take-up roller with release film and an empty take-up roller are installed. The release film passes between the blade 503 and the limiting strip 5. The fourth motor 4 rotates, the cleaning roller 401 rotates to clean the release film. The second motor 301 rotates, the reciprocating screw 302 rotates, and the moving block 304 moves back and forth. The third motor 305 and the brush 306 move accordingly. The brush 306 moves left and right relative to the cleaning roller 401. At the same time, the brush 306 rotates, which can brush off the dust on the surface of the cleaning roller 401. The brushed dust is sucked away by the tube 601. When cutting is required, the second telescopic rod 502 is activated, the blade 503 moves, and the blade 503 abuts against the limiting strip 5, and the release film is cut.
