[0001] This utility model relates to the technical field of self-adhesive protective film equipment, and in particular to an anti-sticking guide roller specifically for self-adhesive protective film equipment. Background Technology

[0002] Self-adhesive protective film is a new type of functional material widely used in various fields. It possesses excellent protective, adhesive, and sealing properties. With continuous technological advancements and expanding application scenarios, the market size of self-adhesive protective film has steadily increased in recent years. This is mainly attributed to the increased demand for diversified products and consumers' growing awareness of product protection.

[0003] Existing self-adhesive protective film equipment often encounters problems when conveying self-adhesive protective films. Due to the adhesive nature of the film, it tends to stick to the surface of the guide rollers during the conveying process, leading to issues such as roller wrapping, wrinkling, and folding. This can damage the protective film or cause production interruptions, affecting production efficiency and product quality. Utility Model Content

[0004] The purpose of this invention is to solve the problems of low detection efficiency and easy detection errors in traditional repetitive point selection and control detection, and to propose a special anti-sticking guide roller for self-adhesive protective film equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dedicated anti-sticking guide roller for self-adhesive protective film equipment includes a frame and a guide roller, wherein the frame is equipped with an anti-sticking mechanism that can adjust the guiding position of the guide roller.

[0007] The anti-sticking mechanism includes a first motor fixedly mounted on the frame. The frame has symmetrical grooves on both sides. A lifting assembly capable of adjusting the position of the guide roller is mounted on the groove. The lifting assembly is also equipped with an airflow assembly capable of preventing the guide roller from sticking to the protective film, and a cleaning assembly capable of cleaning the guide roller and the protective film.

[0008] As a further description of the above technical solution:

[0009] The lifting assembly includes a lead screw rotatably mounted on the groove, a slider threaded onto the surface of the lead screw, a gear fixedly connected to the surface of each lead screw, and a synchronous belt meshing between two gears.

[0010] As a further description of the above technical solution:

[0011] The airflow assembly includes a rotating rod rotatably mounted between two sliders. A second motor is fixedly mounted on one side of one of the sliders, and an air groove is opened on one side of the other slider. An air supply pipe is connected to one side of the air groove. Several air inlet pipes are equidistantly mounted on the surface of the rotating rod, and several air nozzles are connected to the air inlet pipes. Several through holes are opened on the surface of the guide roller.

[0012] As a further description of the above technical solution:

[0013] One end of the rotating rod is fixedly installed on the output end of the second motor, the guide roller is fixedly installed on the rotating rod, and the air inlet pipe extends to the outside of the guide roller from the side near the air groove.

[0014] As a further description of the above technical solution:

[0015] The positions of the air nozzle and the through hole are corresponding. One of the lead screws is fixedly installed on the output end of the first motor. One end of the air supply pipe is connected to the air pump. The unwinding roller is rotatably connected to one side of the frame.

[0016] As a further description of the above technical solution:

[0017] The cleaning assembly includes a brush rotatably mounted between the two sliders, a torsion spring fixedly connected to the connection between the brush and the slider, several arc-shaped blocks fixedly mounted on the top of the brush, a collection box inserted between the two sliders, and a scraper fixedly mounted on one side of the collection box.

[0018] As a further description of the above technical solution:

[0019] The scraper is inclined, and one side of the scraper is in contact with the surface of the guide roller. The brush is located below the collection box.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0021] 1. By incorporating an anti-sticking mechanism, when the self-adhesive protective film is conveyed through the guide roller, gas is delivered to the air inlet pipe via the air supply pipe. Then, the gas is sprayed out from the guide roller through the nozzles and corresponding through holes on the air inlet pipe, forming a stable airflow film between the guide roller and the self-adhesive protective film. At the same time, Teflon coating is applied to the surface of the guide roller, which can effectively prevent the protective film from sticking to the guide roller and improve production efficiency and product quality.

[0022] 2. The brush in the cleaning component can clean the self-adhesive protective film, preventing impurities and dust from sticking to its surface. At the same time, the scraper can clean the surface of the guide roller, ensuring that the guide roller surface is always smooth. By setting up a lifting component, two synchronously rotating lead screws cause the two sliders to rise and fall synchronously, which in turn drives the guide roller to rise and fall. This allows the guide roller to move to the appropriate position according to the usage requirements, increasing the number of application scenarios. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0035] like Figure 1 - Figure 6 As shown, the present invention provides an anti-adhesion guide roller for self-adhesive protective film equipment, including a frame 10 and a guide roller 20. The frame 10 is equipped with an anti-adhesion mechanism 30 that can adjust the guiding position of the guide roller 20.

[0036] The anti-sticking mechanism 30 includes a first motor 31 fixedly mounted on the frame 10. The frame 10 has symmetrically provided grooves 32 on both sides. The grooves 32 are equipped with lifting components 33 that can adjust the position of the guide roller 20. The lifting components 33 are also equipped with airflow components 34 that can prevent the guide roller 20 from sticking to the protective film, and cleaning components 35 that can clean the guide roller 20 and the protective film.

[0037] like Figure 2 - Figure 3 As shown, the lifting assembly 33 includes a lead screw 331 rotatably mounted on the groove 32. A slider 332 is threadedly connected to the surface of the lead screw 331. The slider 332 can be raised and lowered by rotating the lead screw 331. A gear 333 is fixedly connected to the surface of each lead screw 331. A synchronous belt 334 meshes between two gears 333. When the position of the guide roller 20 needs to be adjusted, the first motor 31 is started to drive the lead screw 331 connected to it to rotate. At this time, the rotating lead screw 331 will drive the corresponding gear 333 to rotate. Through the meshing rotation of the synchronous belt 334, the two lead screws 331 will rotate synchronously, thereby causing the sliders 332 on both sides to drive the guide roller 20 to rise or fall.

[0038] like Figure 4 - Figure 5As shown, the airflow assembly 34 includes a rotating rod 341 rotatably mounted between two sliders 332. A second motor 342 is fixedly mounted on one side of one slider 332, and an air groove 343 is formed on one side of the other slider 332. An air supply pipe 344 is connected to one side of the air groove 343. The air supply pipe 344 is a flexible hose with a slack. A regulating valve is also provided on the air supply pipe 344 to regulate the air pressure. Gas is delivered to the air groove 343 through the air supply pipe 344. Several air inlet pipes 345 are fixedly mounted on the surface of the rotating rod 341. The air inlet pipes 345 are equidistant from each other. A plurality of air nozzles 346 are connected to the guide roller 20. Gas enters the air inlet pipe 345 at the bottom of the guide roller 20 through the air groove 343, and then is ejected through the plurality of air nozzles 346 on the air inlet pipe 345. A plurality of through holes 347 are opened on the surface of the guide roller 20. The gas ejected through the plurality of air nozzles 346 will be ejected from the guide roller 20 through the corresponding through holes 347, so that a stable airflow film is formed between the self-adhesive protective film and the guide roller 20, thereby preventing the self-adhesive protective film from sticking together when it is conveyed by the guide roller 20. At the same time, the surface of the guide roller 20 is also coated with Teflon coating, thereby further preventing the guide roller 20 from sticking to the self-adhesive protective film.

[0039] In more detail, one end of the rotating rod 341 is fixedly installed on the output end of the second motor 342. The second motor 342 can drive the rotating rod 341 to rotate. The guide roller 20 is fixedly installed on the rotating rod 341. The rotating rod 341 drives the guide roller 20 to rotate, thereby conveying the self-adhesive protective film. The side of the air inlet pipe 345 near the air groove 343 extends to the outside of the guide roller 20, so that gas can enter the air inlet pipe 345.

[0040] In use, by pulling out the open end of the self-adhesive protective film on the unwinding roller, the self-adhesive protective film passes through the bottom of the guide roller 20. The guide roller 20 applies downward pressure to the self-adhesive protective film, making the self-adhesive protective film taut. Then, the second motor 342 is started to drive the rotating rod 341 to rotate, which in turn drives the guide roller 20 to rotate, thereby conveying the self-adhesive protective film.

[0041] While conveying, the air pump is started, and the air pump delivers gas through the air pipe 344 to the air groove 343. At this time, the air inlet pipe 345 located at the bottom of the guide roller 20 will be located in the air groove 343. The air groove 343 allows the gas to enter the corresponding air inlet pipe 345. Then, the gas is sprayed out through several air nozzles 346 and sprayed out from the guide roller 20 through the corresponding through hole 347, so that a stable airflow film is formed between the self-adhesive protective film and the guide roller 20, thereby preventing the self-adhesive protective film from sticking together when conveyed by the guide roller 20.

[0042] In more detail, the positions of the air nozzle 346 and the through hole 347 correspond. The gas ejected through the air nozzle 346 can be ejected from the guide roller 20 through the corresponding through hole 347. One of the lead screws 331 is fixedly installed on the output end of the first motor 31. The first motor 31 can drive the lead screw 331 connected to it to rotate. One end of the air supply pipe 344 is connected to the air pump. The air pump enables the gas to be transported through the air supply pipe 344. A unwinding roller is rotatably connected to one side of the frame 10. The unwinding roller is fixed to the frame 10 by a buckle. In use, the unwinding roller can be disassembled by opening the buckle between the unwinding roller and the frame 10, and then the self-adhesive protective film roll is installed on the unwinding roller.

[0043] like Figure 6 As shown, the cleaning assembly 35 includes a brush 351 rotatably mounted between two sliders 332, which, as the self-adhesive protective film roll passes through the bottom of the guide roller 20, ... Figure 7 As shown, one side of the self-adhesive protective film will be tilted due to the downward pressure of the guide roller 20, and the brush 351 will be located at the bottom of the self-adhesive protective film to clean the bottom of the self-adhesive protective film. A torsion spring 352 is fixedly connected at the connection between the brush 351 and the slider 332, and the brush 351 can be reset through the torsion spring 352.

[0044] Several arc-shaped blocks 353 are fixedly installed at the top of the brush 351. When the self-adhesive protective film is subjected to downward pressure by the guide roller 20, it will also squeeze the arc-shaped blocks 353. The squeezed arc-shaped blocks 353 will then rotate through the brush 351, such as... Figure 7 As shown, after rotation, the brush 351, through the arc-shaped blocks 353 on both sides, will have the same inclination as the self-adhesive protective film, so that the brush 351 can always adhere to the self-adhesive protective film, thereby cleaning the bottom of the self-adhesive protective film. At the same time, through the reaction force of the torsion spring 352, the arc-shaped blocks 353 will also exert an upward force on the self-adhesive protective film, which, together with the guide roller 20, exerts a downward force, keeping the self-adhesive protective film in a taut state, thereby preventing the self-adhesive protective film from wrinkling during transportation. A collection box 354 is inserted between the two sliders 332, and a scraper 355 is fixedly installed on one side of the collection box 354.

[0045] In more detail, the scraper 355 is inclined, and one side of the scraper 355 is in contact with the surface of the guide roller 20. When the guide roller 20 conveys the self-adhesive protective film, it will rotate towards the side of the scraper 355. At this time, the scraper 355 can clean the impurities remaining on the guide roller 20, so that the surface of the guide roller 20 is always a smooth plane. The cleaned impurities will enter the collection box 354 through the scraper 355 and be collected. The collection box 354 can be removed from the slider 332 by pulling it upward. The brush 351 is located below the collection box 354. When the brush 351 is reset by the torsion spring 352, the reaction force of the torsion spring 352 will make the brush 351 swing back and forth. The swinging can realize the self-cleaning of the brush 351.

[0046] Working principle: In use, by pulling out the open end of the self-adhesive protective film on the unwinding roller, the self-adhesive protective film passes through the bottom of the guide roller 20. The guide roller 20 applies downward pressure to the self-adhesive protective film, and at the same time, the self-adhesive protective film also squeezes the arc-shaped block 353. The squeezed arc-shaped block 353 is then rotated by the brush 351. The rotating brush 351, through the arc-shaped blocks 353 on both sides, has the same inclination as the self-adhesive protective film, so that the brush 351 can always adhere to the self-adhesive protective film, thereby cleaning the bottom of the self-adhesive protective film. At the same time, the reaction force of the torsion spring 352 also causes the arc-shaped block 353 to exert an upward force on the self-adhesive protective film, which, together with the downward force applied by the guide roller 20, keeps the self-adhesive protective film in a taut state, thereby preventing the self-adhesive protective film from wrinkling during conveying. Then, the second motor 342 is started to drive the rotating rod 341 to rotate, so that the rotating rod 341 drives the guide roller 20 to rotate, thereby conveying the self-adhesive protective film.

[0047] While conveying, the air pump is started, and the air pump delivers the gas through the air pipe 344 to the air groove 343. At this time, the air inlet pipe 345 located at the bottom of the guide roller 20 will be located in the air groove 343. The gas enters the corresponding air inlet pipe 345 through the air groove 343, and then the gas is sprayed out through several air nozzles 346 and sprayed out from the guide roller 20 through the corresponding through hole 347, so that a stable airflow film is formed between the self-adhesive protective film and the guide roller 20, thereby preventing the self-adhesive protective film from sticking together when conveyed by the guide roller 20.

[0048] When the position of the guide roller 20 needs to be adjusted, the first motor 31 is started to drive the lead screw 331 connected to it to rotate. At this time, the rotating lead screw 331 will drive the corresponding gear 333 to rotate. Through the meshing rotation of the synchronous belt 334, the two lead screws 331 will rotate synchronously, thereby causing the sliders 332 on both sides to drive the guide roller 20 to rise or fall.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
