Description
Technical Field
[0001] The present invention relates to the technical field of gear pump transportation, and specifically to a polymer film and its preparation process. Background Art
[0002] A gear pump is a rotary pump that relies on the change and movement of the working volume formed between the pump cylinder and the meshing gears to transport liquids or increase their pressure. It consists of two gears, a pump body, and front and rear covers that form two closed spaces. When the gears rotate, the volume of the space on the side where the gears disengage increases from small to large, creating a vacuum and sucking in the liquid. The volume of the space on the side where the gears mesh decreases from large to small, squeezing the liquid into the pipeline. In the production of polymer films, a gear pump is often used as a transportation device to transport polymer resin raw materials.
[0003] Publication No.: CN220581261U discloses a waterproof structure for a gear pump, including a housing. One end of the housing is rotatably connected to a driving mechanism for driving a drying device to move. A drying device is arranged inside the housing, and the driving mechanism meshes with the drying device. The drying device is used to dry the gear pump. The housing is slidably connected to a pushing mechanism for fixing the gear pump. The driving mechanism includes a rotating handle rotatably connected to the housing. A driving rack is fixedly connected to the contact surface between the rotating handle and the housing, and the driving rack meshes with the drying device. The drying device includes a sealing plate and a delay controller. The sealing plate is slidably connected to the inner surface of the housing. A meshing groove is formed on the contact surface between the sealing plate and the housing, and the meshing groove meshes with a bevel gear of the driving rack. The sealing plate cooperates with the delay controller. This device can effectively dry the gear pump, improve waterproof performance, and prevent water from entering the inside of the gear pump. However, in actual use, when this device and existing equipment use a gear pump to transport raw materials, the raw materials are not processed, resulting in the precipitation in the raw materials being prone to collide with various components inside the gear pump, damaging the components inside the gear pump and reducing the overall service life of the gear pump. There is room for further improvement in the protection of the gear pump when transporting raw materials. Summary of the Invention

The first movable wheel 311 rotates through the movable belt 33 to drive the second movable wheel 320 to rotate. The second movable wheel 320 rotates through the first shaft rod 32 to drive the adjusting arm 410 to rotate. The adjusting arm 410 rotates to drive the rotating rod 411 to rotate. The rotating rod 411 rotates to drive the first return groove plate 42 to do reciprocating linear motion. The first return groove plate 42 The movement drives the first connecting plate 420 and the second connecting plate 422 to make a linear reciprocating motion. The first connecting plate 420 and the telescopic plate 421 are used to limit the movement of the first return groove plate 42. The movement of the second connecting plate 422 drives the filter plate 43 to make a linear reciprocating motion through the sliding rod 423. The baffle 430 is used to block the first through groove when the filter plate 43 moves to prevent the leakage of the polymer film production raw materials. When the polymer film production raw materials enter the processing device 4 through the feed bin 40, they will first pass through the filter plate 43. The filter plate 43 will filter the polymer resin precipitate that is not completely dissolved in the polymer film production raw materials to prevent the polymer resin precipitate from colliding with the various components inside the conveying device 5. The filtered polymer film production The raw materials enter the conveying bin 45 through the through hole of the push rod 450, and then the conveying bin 45 conveys the filtered polymer film production raw materials to the conveying device 5 through the inlet pipe 50. During this process, the reciprocating linear motion of the filter plate 43 causes the push rod 450 to continuously penetrate into the filter holes of the filter plate 43 to prevent the filter holes of the filter plate 43 from being blocked by polymer resin, thereby reducing the conveying efficiency of the device. The length of the push rod 450 is less than the depth of the filter hole. When the above steps are running, the control center 30 is used to turn on the second rotary drive component 432. The second rotary drive component 432 is turned on to drive the screw 433 to rotate. The screw 433 rotates through the movable block 435 to drive the scraper plate 434 to move downward. The scraper plate 434 moves to remove the filter holes blocked by the push rod The polymer resin that is pressed against by rod 450 is scraped off to prevent the polymer resin from sticking to the edge of the filter hole and causing a decrease in the conveying efficiency of the device. The push rod 450 moves downward to scrape the polymer resin into the collecting groove of the collecting bin 44. At this time, the scraping plate 434 applies pressure to the two card plates 442 to cause the two elastic members 441 to produce compressed elastic deformation. The card plates 442 move under the influence of the elastic deformation so that the scraping plate 434 can normally scrape the incompletely dissolved polymer resin into the collecting bin 44. After the scraping plate 434 is reset, the elastic deformation of the two elastic members 441 is reset so that the two card blocks are reset to block the incompletely dissolved polymer resin. The polymer film production raw materials scraped in by the scraping plate 434 will be screened out from the collecting bin 44 under the action of the screening holes 443.Enable the device to filter the raw materials for polymer film production, avoid the sediment in the raw materials for polymer film production from easily bumping into subsequent components, thereby reducing the overall service life of the device body 2, improving the filtering effect of the device, and facilitating user use; In the above steps, the rotating shaft 310 rotates to drive the first bevel gear 51 and the second gear disc 530 to rotate. The rotation of the second gear disc 530 drives the third gear disc 531 to rotate. At the same time, the rotation of the second gear disc 530 and the third gear disc 531 can transport the raw materials for polymer film production conveyed by the inlet pipe 50 into the discharge pipe 500 (this is the working principle of a gear pump in the prior art and will not be elaborated further). Since the contact ratio of the meshing of the second gear disc 530 and the third disc is greater than one, part of the raw materials for polymer film production is trapped between the closed cavities formed by the second gear disc 530 and the third gear disc 531. This closed cavity will gradually decrease and increase during the rotation of the second gear disc 530 and the third gear disc 531, thereby causing the raw materials for polymer film production to be squeezed, generating noise and vibration, and damaging the components inside the conveying device 5. During this process, the first bevel gear 51 rotates to drive the second bevel gear 520 to rotate. The rotation of the second bevel gear 520 rotates through the movable rod 521. The rotation of the movable rod 521 drives the first gear disc 522 to rotate. Since the first gear disc 522 has only half of the teeth, the rotation of the first gear disc 522 can drive the second return groove plate 523 to perform a linear reciprocating motion. The movement of the second return groove plate 523 drives the pull plate 524 to perform a reciprocating linear motion. The movement of the pull plate 524 drives the piston plate 525 to move inside the pull chamber 526. When the above phenomenon occurs in the second gear disc 530 and the third gear disc 531, the air pressure in the closed cavity formed by the second gear disc 530 and the third gear disc 531 increases, thereby transporting part of the raw materials for polymer film production to the pull head 529 through the pull hole. The pressure relief groove at the top of the pull head 529 can communicate the closed cavity with the outside in time to relieve pressure when the air pressure in the closed cavity increases and transports part of the raw materials for polymer film production. At this time, the forward movement of the piston plate 525 can cause part of the raw materials for polymer film production in the pull head 529 to enter the pull chamber 526 through the pull pipe. The second one-way valve 528 is used to prevent the raw materials for polymer film production at the discharge pipe 500 from flowing back. The linear reciprocating motion of the piston plate 525 to reset can transport the part of the raw materials for polymer film production drawn in through the conveying pipe 5260 to the discharge pipe 500 for discharge together, thereby avoiding damage to the components in the conveying device 5, avoiding damage to the conveying device 5 caused by the phenomenon of trapped oil inside the conveying device 5, improving the service life of the device, facilitating user use, and the conveying device 5 transports the processed raw materials for polymer film production to the extruder; Production, the extruder extrudes the raw materials for polymer film production into the shaping machine, and through the shaping and air drying of the shaping machine, it forms a polymer film finished product.
