Description

Technical Field

[0001] This utility model relates to the field of polyimide film production technology, specifically to a polyimide film fragmentation adsorption device. Background Technology

[0002] Polyimide film, as a high-performance organic polymer material, possesses excellent high-temperature resistance, chemical corrosion resistance, and superior mechanical properties, making it widely and critically used in numerous high-end fields such as electronics, aerospace, and new energy. However, film breakage is inevitable during the production, processing, transportation, and subsequent use of polyimide film.

[0003] In the production process, factors such as the cutting and winding of the film, friction between the mechanical cutting tool and the film, and uneven tension can easily cause the film edges to break, producing small film fragments. When these fragments are mixed into the products being wound up, they will seriously affect the product quality. Therefore, a polyimide film fragment adsorption device is proposed to solve the above-mentioned problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a polyimide thin film fragmentation adsorption device to address the shortcomings of the prior art.

[0005] To solve the above technical problems, the technical solution adopted by this utility model is: a polyimide film crushing and adsorption device, including a base plate, two support plates fixedly connected to the top of the base plate, each of the two support plates having a "U" shaped groove, a winding roller being slidably connected between the two support plates through the "U" shaped groove, and a film crushing and adsorption mechanism being provided on the base plate.

[0006] The film fragment adsorption mechanism includes: a fixed plate and a collection box. The fixed plate is fixedly connected to the top of the base plate. A sleeve is fixedly connected to the left side of the fixed plate. A sleeve rod is slidably connected to the inner wall of the sleeve. A scraper is fixedly connected to the left end of the sleeve rod. A sponge block is adhered to the left side of the scraper. The left side of the sponge block is in contact with the outer wall of the take-up roller. A spring is fixedly connected to the right end of the sleeve rod. The right end of the spring is fixedly connected to the inner wall of the sleeve. An air suction pipe is fixedly connected to the bottom of the scraper. The air suction port of the air suction pipe is close to the bottom of the sponge block. The collection box is fixedly connected to the top of the base plate. A fan is connected to the back of the collection box via a bracket and is in communication with it. A telescopic hose is fixedly connected to the front of the collection box and is in communication with it. The end of the telescopic hose away from the collection box is in communication with the air suction pipe.

[0007] Preferably, there are two of each of the sleeve, sleeve rod, and spring, and they are arranged opposite each other on the left side of the fixed plate.

[0008] Preferably, a filter screen is fixedly connected to the inner wall of the collection box, and is located near the inner wall of the back of the collection box.

[0009] Preferably, the right side of the collection box is hinged to a door, and a magnetic sealing strip is provided between the door and the collection box.

[0010] Preferably, a motor is connected to the back of the rear support plate via a bracket, and the output end of the motor is fixedly connected to a rotating shaft via a coupling. The front end of the rotating shaft is connected to a take-up roller.

[0011] Preferably, the base plate is provided with a tension adjustment mechanism, which includes: two fixed frames, both of which are inverted "L" shapes and are fixedly connected to the top of the base plate. A second spring is fixedly connected to the inner side of the top of each fixed frame, and a mounting frame is fixedly connected to the bottom end of the two second springs. The mounting frame is inverted "U" shape and is slidably connected to the two fixed frames on its front and rear sides respectively. A pressure roller is rotatably connected to the inner cavity of the mounting frame.

[0012] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0013] 1. This polyimide film fragment adsorption device uses a scraper and a sponge block to scrape away film fragments from the film surface as the winding roller rotates. Simultaneously, a blower is activated to create negative pressure inside the collection box. Air is drawn in through a telescopic hose and suction pipe from the bottom air inlet of the sponge block, adsorbing the scraped film fragments and transporting them to the collection box via the telescopic hose. As the film winding thickness increases, the sponge block and scraper are pushed forward. The scraper pushes the sleeve rod, which slides along the inner wall of the sleeve and compresses the first spring. Under the elastic force of the first spring, the sponge block remains in contact with the film, ensuring stable scraping and adsorption effects of the sponge block and scraper on the winding film. This effectively removes film fragments and impurities from the film surface, preventing film fragments from mixing into the wound product and affecting quality, thus improving the product's pass rate and quality.

[0014] 2. This polyimide film crushing adsorption device, during the film winding process, the pressure roller is in close contact with the film under the action of spring two. The position of the pressure roller is automatically adjusted according to the tension change of the film to keep the film under appropriate tension. This helps the film to be wound evenly and flatly on the winding roller, avoiding problems such as wrinkles, looseness or excessive stretching, ensuring winding quality, improving the appearance quality and performance stability of the product, and reducing product defects caused by tension problems.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" means two or more, unless otherwise explicitly specified.

[0024] Please see Figure 1-4 One embodiment of this utility model is: a polyimide film fragmentation adsorption device, including a base plate 1, with two support plates 2 fixedly connected to the top of the base plate 1. Each support plate 2 has a U-shaped groove. A winding roller 3 is slidably connected between the two support plates 2 through the U-shaped groove. A motor 6 is connected to the back of the rear support plate 2 via a bracket. The output end of the motor 6 is fixedly connected to a rotating shaft 7 via a coupling. The front end of the rotating shaft 7 is connected to the winding roller 3. Starting the motor 6 drives the rotating shaft 7 to rotate, which in turn drives the winding roller 3 to wind up the film. A film fragmentation adsorption mechanism 4 is provided on the base plate 1. The film fragmentation adsorption mechanism 4 includes: a fixed plate 41 and a collection box 48. The fixed plate 41 is fixedly connected to the top of the base plate 1. A sleeve 42 is fixedly connected to the left side of plate 41. A sleeve rod 43 is slidably connected to the inner wall of sleeve 42. A scraper 44 is fixedly connected to the left end of sleeve rod 43. A sponge block 45 is adhered to the left side of scraper 44. The left side of sponge block 45 is in contact with the outer wall of the take-up roller 3. A spring 46 is fixedly connected to the right end of sleeve rod 43. The right end of spring 46 is fixedly connected to the inner wall of sleeve 42. There are two sleeves 42, two sleeve rods 43, and two springs 46, which are arranged opposite each other on the left side of fixed plate 41. An air suction pipe 47 is fixedly connected to the bottom of scraper 44. The air suction port of air suction pipe 47 is close to the bottom of sponge block 45. A collection box 48 is fixedly connected to the top of base plate 1. A fan 49 is connected to the back of collection box 48 through a bracket and is connected to... The collection box 48 is equipped with a telescopic hose 410 fixedly connected to its front side. The end of the telescopic hose 410 away from the collection box 48 is connected to an air suction pipe 47. The scraper 44 and sponge block 45 scrape away film fragments from the film surface when the winding roller 3 rotates. Simultaneously, the exhaust fan 49 is activated to create negative pressure inside the collection box 48. Air is drawn in through the telescopic hose 410 and air suction pipe 47 from the bottom air intake of the sponge block 45, adsorbing the scraped film fragments and transporting them to the collection box 48 via the telescopic hose 410. As the film winding thickness increases, the sponge block 45 and scraper 44 are pushed. The scraper 44 pushes the sleeve rod 43, which slides along the inner wall of the sleeve 42 and compresses the spring 46. Under the elastic force of the spring 46, the sponge block 45... The constant contact with the film ensures stable scraping and adsorption of the winding film by the sponge block 45 and scraper 44, effectively removing film fragments and impurities from the film surface, preventing film fragments from entering the winding product and affecting quality, thus improving the product qualification rate and quality. The inner wall of the collection box 48 is fixedly connected to a filter screen plate 411, which is close to the back inner wall of the collection box 48. The filter screen plate 411 filters the air and blocks film fragments, preventing them from entering the exhaust fan 49 and causing damage, thus extending the service life of the exhaust fan 49. The right side of the collection box 48 is hinged to a door 412, and a magnetic sealing strip is provided between the door 412 and the collection box 48. Opening the door 412 makes it easy to clean the film fragments inside the collection box 48.

[0025] Working principle: The motor 6 drives the rotating shaft 7 to rotate, which in turn drives the winding roller 3 to rotate and wind up the film. The scraper 44 and sponge block 45 scrape off film fragments on the film surface as the winding roller 3 rotates. At the same time, the exhaust fan 49 is activated to create a negative pressure in the collection box 48. Air is drawn in through the air inlet at the bottom of the sponge block 45 via the telescopic hose 410 and the suction pipe 47. The scraped film fragments are adsorbed and transported to the collection box 48 through the telescopic hose 410. As the film winding thickness increases, the sponge block 45 and scraper 44 are pushed. The scraper 44 pushes the sleeve rod 43 to slide along the inner wall of the sleeve 42 and compresses the spring 46. Under the elastic force of the spring 46, the sponge block 45 is always in contact with the film, ensuring the stable scraping and adsorption effect of the sponge block 45 and scraper 44 on the winding film, effectively removing film fragments and impurities from the film surface.

[0026] Please see Figure 1-4 Based on the above embodiments, in another embodiment of this utility model, a tension adjustment mechanism 5 is provided on the base plate 1. The tension adjustment mechanism 5 includes two fixed frames 51, both of which are inverted "L" shapes and are fixedly connected to the top of the base plate 1. A second spring 52 is fixedly connected to the inner side of the top of each fixed frame 51. A mounting frame 53 is fixedly connected to the bottom end of the two second springs 52. The mounting frame 53 is inverted "U" shape and is slidably connected to the two fixed frames 51 on its front and rear sides respectively. A pressure roller 54 is rotatably connected to the inner cavity of the mounting frame 53. During the film winding process, the pressure roller 54 is in close contact with the film under the action of the second spring 52. The position of the pressure roller 54 is automatically adjusted according to the tension change of the film to keep the film under appropriate tension. This helps the film to be wound evenly and flatly on the winding roller 3, avoiding problems such as wrinkles, looseness or overstretching, ensuring winding quality, improving the appearance quality and performance stability of the product, and reducing product defects caused by tension problems.

[0027] Working principle: During the film winding process, the pressure roller 54 is in close contact with the film under the action of the second spring 52. When the film is wound too tightly, the pressure roller 54 is squeezed, causing the pressure roller 54 to drive the mounting frame 53 to compress the second spring 52 and rise. When the film is wound too loosely, the mounting frame 53 and the pressure roller 54 descend under the elastic force of the second spring 52. This allows the position of the pressure roller 54 to be automatically adjusted according to the tension change of the film, so that the film maintains appropriate tension. This helps the film to be wound evenly and flatly on the winding roller 3, avoiding problems such as wrinkles, looseness or excessive stretching.

[0028] It is worth noting that the exhaust fan 49, motor 6, and magnetic sealing strip in the above embodiments are all commonly used devices in the prior art. The models used can be customized according to actual usage requirements. Furthermore, the power supply interface of the electrical equipment in this utility model is connected to the power supply system through a switch (not shown in the figure) and wires (not shown in the figure) to achieve control. The circuit control, specific composition, and principle involved are all prior art and are well known in the current field. They are clear to those skilled in the art, so they will not be described in detail here.
