Technical Field

[0001] This invention belongs to the field of thin film production technology, specifically relating to a high-precision material filter for thin film production. Background Technology

[0002] A film is a thin, soft, transparent sheet made of plastics, adhesives, rubber, or other materials. Films are widely used in industries such as electronics, machinery, and printing. During the production of plastic films, raw materials are crushed into granular materials for subsequent processing. If the particle size difference is too large, it will lead to uneven density of the melted processed material, affecting the quality of plastic film forming. Therefore, the material needs to be filtered.

[0003] Currently, during the material filtration process, materials tend to accumulate near the filter inlet, causing blockages and affecting the feeding speed. When filtering materials, the filter screen may allow materials that meet the particle size requirements but are too long to pass through, affecting the quality of the molded products.

[0005] The specific technical solution adopted in this utility model is as follows: A high-precision material filter for thin film production, comprising: A filter barrel, wherein a filter plate is installed at the bottom of the filter barrel; A material unloading mechanism is installed inside the filter barrel and is used to unblock the flow of materials during material feeding. A cutting mechanism is provided at the bottom of the filter barrel. The cutting mechanism is used to cut excessively long materials when the filter plate is filtering materials.

[0006] In a preferred embodiment, the top of the filter barrel is connected to a feed hopper, the bottom outer side of the filter barrel is connected to a discharge pipe, a valve is installed on the discharge pipe, a base plate is provided below the filter barrel, four support columns are fixedly provided between the filter barrel and the base plate, a symmetrical collection box is provided on the top surface of the base plate, four fan-shaped grooves are provided through the bottom surface of the filter barrel, filter plates are attached to the inner walls of the fan-shaped grooves, and multiple filter holes are provided through the top surface of the filter plates.

[0007] In a preferred embodiment, a scraping mechanism is provided on the top surface of the base plate. The scraping mechanism includes a servo motor, a rotating shaft, a connecting rod, and a first scraper. The servo motor is fixedly installed on the top surface of the base plate. A rotating shaft is fixedly provided at the output end of the servo motor. The rotating shaft passes through the filter barrel to the inside of the filter barrel and is rotatably connected to the filter barrel.

[0008] In a preferred embodiment, the material feeding mechanism includes a fixed rod, a mounting box, a first bevel gear, a second bevel gear, a rotating rod, a lifting plate, a T-shaped slider, a T-shaped groove, and a material feeding rod. Symmetrical fixed rods are fixedly installed on the inner wall of the filter barrel. A mounting box is fixedly installed at the end of each fixed rod away from the filter barrel. A first bevel gear is fixedly installed on the top surface of the rotating shaft. A second bevel gear meshes with the outer side of the first bevel gear. A rotating rod is fixedly installed on the side of the second bevel gear. A lifting plate is slidably connected to the inner wall of the mounting box. Symmetrical T-shaped sliders are fixedly installed on the front and rear sides of the lifting plate. A T-shaped groove adapted to the T-shaped slider is provided on the inner wall of the mounting box. The T-shaped slider is slidably connected to the mounting box through the T-shaped groove. A material feeding rod is fixedly installed on the top surface of the lifting plate.

[0009] In a preferred embodiment, the bottom surface of the first bevel gear is rotatably connected to the mounting box, the side surface of the second bevel gear is rotatably connected to the mounting box via a bearing, the side surface of the lifting plate is provided with a through groove adapted to the rotating rod, the rotating rod is movably connected to the lifting plate via the through groove, and the material unloading rod passes through the mounting box to the outside of the mounting box and is slidably connected to the mounting box.

[0011] The technical effects achieved by this utility model are as follows: This utility model, by setting up a material unloading mechanism, allows the scraping mechanism to drive the unloading rod to move up and down periodically when the material is fed into the hopper. When the material accumulates at the bottom opening of the hopper and causes blockage, the unloading rod moves upward into the hopper and then downward, which can drive the material to move up and down and change the relative position between the material particles, so that the material continues to move downward. The unloading rod can remove the blockage in the hopper by moving up and down multiple times, thus unblocking the material. This invention incorporates a cutting mechanism. When the filter plate filters materials, materials that meet the particle size requirements enter the filter holes of the filter plate and fall onto the top surface of the baffle. As the baffle rotates, the materials move along the notch to the outside of the filter holes and fall into the collection box. The rotation of the second scraper drives the material to rotate, which can accelerate the filtration efficiency of the filter plate. When the material is too long, the cutting blade rotates to cut the part of the material that is exposed outside the filter holes, so that the material length meets the requirements.

[0018] Please see the appendix Figures 1 to 2 As shown, this utility model provides a high-precision material filter for film production, including: a filter barrel 100, a material feeding mechanism 500, and a cutting mechanism 600. The top of the filter barrel 100 is connected to a feed hopper 101, and the bottom outer side of the filter barrel 100 is connected to a discharge pipe 102. A valve is installed on the discharge pipe 102. A bottom plate 103 is provided below the filter barrel 100. Four support columns 104 are fixedly provided between the filter barrel 100 and the bottom plate 103. A symmetrical collection box 200 is provided on the top surface of the bottom plate 103. Four fan-shaped grooves are provided through the bottom surface of the filter barrel 100. Filter plates 400 are attached to the inner walls of the fan-shaped grooves.

[0019] In a preferred embodiment, please refer to Figures 1 to 4 A scraping mechanism 300 is provided on the top surface of the base plate 103. The scraping mechanism 300 consists of a servo motor 301, a rotating shaft 302, a connecting rod 303, and a first scraper 304. The servo motor 301 is fixedly installed on the top surface of the base plate 103. The rotating shaft 302 is fixedly installed at the output end of the servo motor 301. The rotating shaft 302 passes through the filter barrel 100 to the inside of the filter barrel 100 and is rotatably connected to the filter barrel 100. Multiple connecting rods 303 are fixedly installed on the outside of the rotating shaft 302. The first scraper 304 is fixedly installed at the end of the connecting rod 303 away from the rotating shaft 302. The first scraper 304 is close to the inner wall of the filter barrel 100. The servo motor 301 controls the rotating shaft 302 to rotate. The rotation of the rotating shaft 302 can drive the connecting rod 303 and the first scraper 304 to rotate. The rotation of the first scraper 304 can scrape off the material on the inner wall of the filter barrel 100 and prevent the material from adhering to the inner wall of the filter barrel 100.

[0020] In a preferred embodiment, please refer to Figures 1 to 3The filter barrel 100 is equipped with a material feeding mechanism 500, which consists of a fixed rod 501, a mounting box 502, a first bevel gear 503, a second bevel gear 504, a rotating rod 505, a lifting plate 506, a T-shaped slider 507, a T-shaped slide groove 508, and a material feeding rod 509. Symmetrical fixed rods 501 are fixedly installed on the inner wall of the filter barrel 100. The mounting box 502 is fixedly installed at the end of the fixed rod 501 away from the filter barrel 100. The first bevel gear 503 is fixedly installed on the top surface of the rotating shaft 302, and the outer side of the first bevel gear 503 is engaged. The first bevel gear 503 and the second bevel gear 504 are both located inside the mounting box 502. A rotating rod 505 is fixedly installed on the side of the second bevel gear 504. A lifting plate 506 is slidably connected to the inner wall of the mounting box 502. Symmetrical T-shaped sliders 507 are fixedly installed on the front and rear sides of the lifting plate 506. A T-shaped groove 508 adapted to the T-shaped slider 507 is provided on the inner wall of the mounting box 502. The T-shaped slider 507 is slidably connected to the mounting box 502 through the T-shaped groove 508. A material unloading rod 509 is fixedly installed on the top surface of the lifting plate 506.

[0021] In this embodiment, the rotating shaft 302 passes through the mounting box 502 to the inside of the mounting box 502 and is rotatably connected to the mounting box 502. The bottom surface of the first bevel gear 503 is rotatably connected to the mounting box 502. The side of the second bevel gear 504 is rotatably connected to the mounting box 502 through a bearing. The side of the lifting plate 506 is provided with a through groove adapted to the rotating rod 505. The rotating rod 505 is movably connected to the lifting plate 506 through the through groove. The unloading rod 509 passes through the mounting box 502 to the outside of the mounting box 502 and is slidably connected to the mounting box 502.

[0022] In this embodiment, when material is fed along the feed hopper 101, the servo motor 301 of the scraping mechanism 300 drives the rotating shaft 302 to rotate, which in turn drives the first bevel gear 503 to rotate. The rotation of the first bevel gear 503 drives the second bevel gear 504 to rotate, and the rotation of the second bevel gear 504 drives the rotating rod 505 to rotate. The rotation of the rotating rod 505 drives the lifting plate 506 to move up and down. At the same time, the rotating rod 505 moves inside the through groove of the lifting plate 506. The T-shaped slider 507 cooperates with the T-shaped slide groove 508 to move the lifting plate 506. The guide plate 506 moves, driving the material unloading rod 509 to move up and down. The rotating shaft 302 rotates continuously at a constant speed, allowing the material unloading rod 509 to move up and down periodically. When material accumulates at the bottom opening of the feed hopper 101 and causes blockage, the material unloading rod 509 moves upward into the feed hopper 101 and then downward, which can drive the material to move up and down and change the relative position between the material particles, allowing the material to continue to move downward. The material unloading rod 509 moves up and down multiple times to remove the blockage from the feed hopper 101 and achieve the unblocking of the material.

[0023] In a preferred embodiment, please refer to Figures 1 to 4A cutting mechanism 600 is provided at the bottom of the filter barrel 100. The cutting mechanism 600 consists of a second scraper 601, a cutting blade 602, and a baffle 603. The cutting blade 602, the baffle 603, and multiple second scrapers 601 are fixedly provided on the outside of the rotating shaft 302. The second scrapers 601 and the cutting blade 602 are located inside the filter barrel 100. The baffle 603 is located on the bottom surface of the filter barrel 100. A notch is provided through the top surface of the baffle 603. The baffle 603 is used to cover the bottom surface of the filter plate 400. The material filtered by the filter plate 400 can only move downward through the notch and fall into the collection box 200.

[0024] In this embodiment, when the filter plate 400 filters the material, the rotating shaft 302 rotates while driving the second scraper 601, the cutting blade 602, and the baffle 603 to rotate. The material that meets the particle size requirements enters the filter hole of the filter plate 400 and falls on the top surface of the baffle 603. As the baffle 603 rotates, the material moves along the notch to the outside of the filter hole and falls into the collection box 200. The rotation of the second scraper 601 drives the material to rotate, which can speed up the filtration efficiency of the filter plate 400. When the material is too long, the rotation of the cutting blade 602 can cut the part of the material that is exposed outside the filter hole, so that the material length meets the requirements.

[0025] The working principle of this utility model is as follows: In use, the device pours the granular material required for film production into the filter barrel 100 through the feed hopper 101. The servo motor 301 drives the rotating shaft 302 to rotate. The rotation of the rotating shaft 302 drives the connecting rod 303 and the first scraper 304 to rotate. The rotation of the first scraper 304 scrapes off the material from the inner wall of the filter barrel 100, preventing material from adhering to it. Simultaneously, the rotation of the rotating shaft 302 drives the first bevel gear 503 to rotate, which in turn drives the second bevel gear 504 to rotate. The rotation of the second bevel gear 504 drives the rotating rod 505 to rotate, which in turn moves the lifting plate 506 up and down. The rotating rod 505 moves inside the through groove of the lifting plate 506. The T-shaped slider 507, in conjunction with the T-shaped slide 508, guides the movement of the lifting plate 506. The movement of the lifting plate 506 drives the material unloading rod 509 to move up and down. The continuous uniform rotation of the rotating shaft 302 can make the material unloading rod 509 move up and down periodically. When the material accumulates at the bottom opening of the feed hopper 101 and causes blockage, the material unloading rod 509 moves upward into the feed hopper 101 and then downward, which can drive the material to move up and down and change the relative position between the material particles, so that the material continues to move downward. The material unloading rod 509 can remove the blockage of the feed hopper 101 by moving up and down multiple times, thus unblocking the material.

[0026] The filter plate 400 screens materials that meet the particle size requirements. As the rotating shaft 302 rotates, it drives the second scraper 601, the cutter 602, and the baffle 603 to rotate. Materials that meet the particle size requirements enter the filter holes of the filter plate 400 and fall onto the top surface of the baffle 603. As the baffle 603 rotates, the material moves along the notch to the outside of the filter holes and falls into the collection box 200. The rotation of the second scraper 601 drives the material to rotate, which can accelerate the filtration efficiency of the filter plate 400. When the material is too long, the cutting knife 602 can cut the part of the material that is exposed outside the filter holes, so that the material length meets the requirements.

[0027] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model shall be implemented according to conventional methods in the art unless otherwise specified or limited.
