Description

Technical Field

[0001] This invention relates to the field of plastic film production technology, and in particular to a plastic film extrusion molding apparatus. Background Technology

[0002] Plastic film extrusion molding is one of the core processes in polymer material processing and is widely used in packaging, agriculture, medical and other fields. Traditional extrusion molding equipment usually includes components such as extruder and die head. Among them, the die head is the key component that determines the thickness, width and uniformity of the film. After long-term use, the die head will absorb and stick to a certain amount of waste material due to the extrusion of hot melt material, which will cause the die head to be contaminated, thus affecting the extrusion quality and production efficiency of the film.

[0003] In existing plastic film production processes, after prolonged use, the surface of the die head may absorb and solidify hot melt waste, forming a sticky residue. When this solidified waste is placed near the die head's outlet, the flowing film will come into contact with this waste during the next extrusion. The remaining waste, with its relatively hard surface and adsorbed impurities, will also come into contact with the extruded film. If this waste is not removed promptly, it will severely impact the quality of the produced film, causing problems such as scratches, uneven thickness, and contamination. These issues not only reduce the film's aesthetics and quality but also increase the proportion of defective products, leading to higher production costs. Furthermore, the long-term accumulation of waste can further damage the die head, shorten its service life, and increase the company's maintenance costs. Additionally, the outside of the die head can become contaminated with machine oil, leading to oil stains adhering to its surface. Therefore, effectively removing waste from the die head is a key issue in improving the quality and efficiency of plastic film production. Traditionally, waste cleaning is done manually, but because the solidified waste adheres tightly to the die head, it is difficult to remove, requiring frequent cleaning. Manual cleaning is inefficient, consuming significant manpower and resources, and also affecting the machine's normal production efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the existing technology has the disadvantage that the dirt near the die head is not easy to clean. To this end, we propose a plastic film extrusion molding device.

[0005] To achieve the above objectives, this application adopts the following technical solution: a plastic film extrusion molding apparatus, comprising an extrusion die, an extruder mounted on the top of the extrusion die, supports fixedly connected to both ends of the top of the extrusion die, a control computer fixedly connected to the surface of the supports, mounting blocks fixedly connected to the surface of the supports, and a cleaning component mounted on the top of the extrusion die, including a scraper and a waste tray, and further comprising: The scraping assembly is used to control the scraper and the waste disk to move synchronously along the surface of the extrusion die, and the scraper moves up and down repeatedly along the surface of the extrusion die during the movement. A material feeding assembly, which is connected to the scraping assembly, is used to tilt the waste material tray by self-deflection after translation. The protective component, in conjunction with the scraping component, is used to remove adhering materials adsorbed on the surface during the movement of the scraper. An adjustment component is used to adjust the distance between the scraper and the extrusion die.

[0006] Preferably, the cleaning component includes a motor, the output end of which is fixedly connected to a lead screw, a sleeve is mounted on the surface of the lead screw, a scraper is mounted on one side of the sleeve, an extension plate is provided at the bottom of the extrusion die, a connecting rod is fixedly connected to the top of the sleeve, and a waste tray is mounted on one side of the connecting rod.

[0007] Preferably, the scraping component includes: A circular hole block is fixedly connected to the surface of a sleeve. A sliding plate is slidably connected inside the circular hole block. A flat plate is fixedly connected to one side of the sliding plate. A sliding column is fixedly connected to the surface of the flat plate. One end of the sliding column is fixedly connected to the sliding plate. An inclined plate is fixedly connected to one side of the mounting block. A wave groove is formed on the surface of the inclined plate. A scraper is fixedly connected to the surface of the extension plate.

[0008] Preferably, the pouring assembly includes: A rotating rod is fixedly connected to one side of the waste tray. A shaft is fixedly connected to the surface of the rotating rod. The shaft is rotatably connected to one end of a connecting rod. A shaped groove plate is fixedly connected between the two brackets. The rotating rod is slidably connected to the inner wall of the shaped groove plate. A storage basket is provided on one side of the bracket.

[0009] Preferably, the protective component includes: A U-shaped plate is fixedly connected to the surface of the circular hole block, and a brush is fixedly connected to one side of the U-shaped plate, with the brush close to the surface of the scraper.

[0010] Preferably, the adjustment component includes: The connecting sleeves are of two types, with one end of the connecting sleeve fixedly connected to the scraper and the other end fixedly connected to the plate. Both ends of the plate are threaded with a rotating rod, and the other end of the rotating rod is rotatably connected to the surface of the scraper.

[0011] Preferably, the length of the inner wall of the sliding plate is greater than the width of the inclined plate, and the length of the groove formed by the flat plate and the sliding plate is greater than the width of the inclined plate.

[0012] Preferably, an arc-shaped plate is fixedly connected to the surface of the scraper, and the arc-shaped plate has an arc-shaped structure.

[0013] Preferably, one side of the inner wall of the waste tray has an arc-shaped structure, and the top of one end of the waste tray gradually concaves from top to bottom towards the other end of the waste tray, and the inner wall of the waste tray is round and smooth.

[0014] The technical effects and advantages of this invention are as follows: I. In this invention, the scraper moves horizontally via a lead screw and a sleeve, and then the sliding connection between the sliding column and the corrugated groove drives the scraper to move up and down repeatedly. This repeated up-and-down movement of the scraper during translation enhances the cleaning effect of the scraper on the surface of the extrusion die by translational scraping and repeated scraping. It is more conducive to removing stubborn dirt from the surface of the extrusion die, so as to avoid the adhesion and contamination that may occur during the film extrusion molding process due to waste material residue and its adverse effects on product quality.

[0015] Second, in this invention, the waste material is collected by the waste tray following the scraper's horizontal movement. After the scraper has finished cleaning, the waste tray tilts due to the self-deflection of the arc-shaped inner wall of the irregular groove plate, and the waste material collected inside the waste tray is poured to one side into the storage basket for centralized storage.

[0016] Third, in this invention, the scraper comes into contact with the brush during repeated movement, so that the brush cleans the scraper by moving up and down, thereby keeping the scraper surface clean and preventing impurities from adhering to the scraper surface and affecting the cleaning effect. Furthermore, it prevents the scraper from adsorbing waste material and causing blockage, which affects the scraping effect on the extrusion die, and ensures the cleanliness of the scraper surface when cleaning waste material.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the invention in a schematic manner, and therefore only show the components relevant to the invention.

[0020] Reference Figures 1-4 As shown, the present invention provides a technical solution: a plastic film extrusion molding device, including an extrusion die 1, an extruder 2 installed on the top of the extrusion die 1, brackets 3 fixedly connected to both ends of the top of the extrusion die 1, a control computer 4 fixedly connected to the surface of the brackets 3, an installation block 5 fixedly connected to the surface of the brackets 3, and a cleaning component installed on the top of the extrusion die 1. Cleaning components include; Motor 6, with lead screw 7 fixedly connected to the output end of motor 6, sleeve 8 installed on the surface of lead screw 7, scraper 9 installed on one side of sleeve 8, extension plate 10 provided at the bottom of extrusion die 1, connecting rod 11 fixedly connected to the top of sleeve 8, and waste tray 12 installed on one side of connecting rod 11. The scraping assembly is used to move the scraper 9 along the surface of the extrusion die 1, and the scraper 9 moves up and down repeatedly along the surface of the extrusion die 1 during the movement. The material feeding assembly is connected to the scraping assembly for tilting the waste material tray 12 after it has been translated and deflected. A protective component is used to remove adhering materials adsorbed on the surface of scraper 9; The adjustment component is used to adjust the distance between the scraper 9 and the extrusion die 1. By setting the cleaning component, the waste material adsorbed by the extrusion die 1 is scraped and cleaned. During the scraping process, the scraper 9 moves repeatedly to generate vibration, shake off the waste material it adsorbs, improve the scraping effect of its own translation on the waste material of the extrusion die 1, and ensure the efficiency and continuity of the cleaning process.

[0021] Reference Figures 1-5 As shown in this embodiment, the scraping component includes: A circular hole block 13 is fixedly connected to the surface of the sleeve 8. A sliding plate 14 is slidably connected inside the circular hole block 13. A flat plate 15 is fixedly connected to one side of the sliding plate 14. A sliding column 16 is fixedly connected to the surface of the flat plate 15. One end of the sliding column 16 is fixedly connected to the sliding plate 14. An inclined plate 17 is fixedly connected to one side of the mounting block 5. A wave groove 18 is formed on the surface of the inclined plate 17. A scraper 19 is fixedly connected to the surface of the extension plate 10. The length of the inner wall of the sliding plate 14 is greater than the width of the inclined plate 17. The length of the groove formed by the flat plate 15 and the sliding plate 14 is greater than the width of the inclined plate 17. When the bottom and sides of the extrusion die 1 absorb impurities or adhere to solidified waste due to the hot melt material of the flowing film during actual use, the operator controls the motor through the control computer 4. 6. Operation causes motor 6 to drive lead screw 7 to rotate. Lead screw 7 is threadedly connected to sleeve 8, and sleeve 8, connected to connecting rod 11 and shaft 21, does not rotate. This allows sleeve 8 to move back and forth along the surface of lead screw 7. Simultaneously, it drives the circular hole block 13 and sliding plate 14, causing scraper 9 to move against the surface of extrusion die 1. Scraper 19 and extension plate 10 also move with the circular hole block 13. Scraper 19 adheres to the bottom of extrusion die 1, and scrape waste material from the surface of extrusion die 1 with scraper 9. Sliding plate 14 slides on the outside of inclined plate 17. Sliding column 16 slides in the wave groove 18 during translation. The wave trajectory of wave groove 18 causes the surface of sliding column 16 to adhere to the inner wall of wave groove 18. Moving along the wave trajectory of the wave groove 18, the sliding column 16 will repeatedly move up and down on the inner wall of the wave groove 18, while also moving horizontally. Through the sliding connection between the sliding plate 14 and the circular hole block 13, the sliding column 16 repeatedly moves up and down, causing the sliding plate 14 to repeatedly move up and down inside the circular hole block 13, and causing the scraper 9 to repeatedly move up and down. When the scraper 9 is scraping away waste material, it will adhere to the surface of the extrusion die 1 and move up and down repeatedly. Through the repeated movement of the scraper 9, it forms a horizontal scraping of waste material on the surface of the extrusion die 1 and vibrates and moves horizontally, improving the scraping effect of stubborn waste material. Through its repeated movement, it also vibrates and shakes off the waste material that is stuck to the scraper 9 when scraping, avoiding the accumulation of too much waste material on itself, which would affect the extrusion. The scraping effect of the extrusion die 1 can remove oil and waste from the device. The waste tray 12 then moves along with the circular hole block 13 and is positioned at the bottom of the scraper 9 and scraper blade 19 to collect the scraped waste falling downwards, thus cleaning the surface of the extrusion die 1 and collecting the waste. This ensures the efficiency and continuity of the scraping process. After cleaning, the motor 6 drives the lead screw 7 in the reverse direction, which in turn drives the sleeve 8 to reset the scraper 9, preparing for the next waste scraping operation. In this device, the number of scrapers 9 can be set to two sets, distributed on both sides of the extrusion die 1. Based on the extrusion angle of the extrusion die 1, the irregular groove plate 22 and connecting rod 11 are appropriately tilted, so that the waste tray 12 is installed at an angle. When the extrusion die 1 tilts to discharge the film...The waste tray 12 is always positioned directly below the waste drop point of the extrusion die 1. It is suitable for extrusion dies 1 at various angles to create film flow. Through the cooperation of two scrapers 9 and a scraper blade 19, the surface of the extrusion die 1 is thoroughly cleaned, removing stubborn impurities such as dirt, oil, and waste, further reducing the impact of dirt on the extrusion die 1 surface on the quality of the extruded film.

[0022] The scraper 9 moves horizontally via the lead screw 7 and sleeve 8. During the movement of the sliding plate 14 and plate 15, the sliding column 16 and the wave groove 18 are connected to each other, which restricts the wave-shaped movement trajectory of the column 16. This causes the column 16 to move up and down repeatedly through the wave groove 18, which drives the sliding plate 14 to slide inside the circular hole block 13. This causes the scraper 9 to move up and down repeatedly during the translation process, achieving its own vibration and translation. While scraping the waste material laterally, it moves longitudinally and repeatedly on the surface of the extrusion die 1, which creates friction on the extrusion die 1. The translation scraping and repeated scraping improve the cleaning effect on the surface of the extrusion die 1, making it easier to remove stubborn dirt from the surface of the extrusion die 1, so as to avoid the adhesion pollution that may occur during the film extrusion molding process and its adverse effects on product quality.

[0023] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown in this embodiment, the pouring assembly includes: A rotating rod 20 is fixedly connected to one side of the waste tray 12. A shaft 21 is fixedly connected to the surface of the rotating rod 20, and the shaft 21 is rotatably connected to one end of the connecting rod 11. A shaped groove plate 22 is fixedly connected between the two supports 3. The rotating rod 20 is slidably connected to the inner wall of the shaped groove plate 22. A storage basket 28 is provided on one side of the support 3. One side of the inner wall of the waste tray 12 has an arc-shaped structure, and the top of one end of the waste tray 12 gradually concaves from top to bottom towards the other end of the waste tray 12. The inner wall of the waste tray 12 is round and smooth. The sleeve 8 moves to drive the connecting rod 11 to pull the shaft 21, which in turn drives the rotating rod 20 to move along the inner diameter of the shaped groove plate 22. The rotating rod 20 slides to one end of the shaped groove plate 22. Due to the arc-shaped structure of one end of the shaped groove plate 22, when the rotating rod 20 moves to the arc, one of the rotating rods 20 will gradually move along the shaped groove. When the inner diameter of plate 22 enters the arc, the other plate remains horizontally positioned on the inner wall of the irregular groove plate 22. At this point, one rotating rod 20 rotates downwards along the arc of the irregular groove plate 22, thereby causing one end of the waste tray 12 to rotate downwards around the other rotating rod 20 as the center. This causes the waste tray 12 to deflect and tilt at a certain angle. The waste collected inside the waste tray 12 slides to one side along the arc structure of the waste tray 12, causing the waste to pour out from inside the waste tray 12 when it tilts. The waste tray 12 is then placed on top of the storage basket 28, which collects the waste poured out of the waste tray 12. This achieves automatic dumping of the waste collected inside the waste tray 12, preventing excessive waste accumulation inside the waste tray 12 and facilitating the transfer and storage of the waste collected in the waste tray 12 during daily use of the device.

[0024] Reference Figure 2 and Figure 3 As shown, in this embodiment, the protective components include: A U-shaped plate 23 is fixedly connected to the surface of the round hole block 13. A brush 24 is fixedly connected to one side of the U-shaped plate 23. The brush 24 is close to the surface of the scraper 9. When the scraper 9 moves up and down repeatedly and moves to one side, the brush 24 is attached to the surface of the scraper 9 and moves with the scraper 9 through the fixed connection between the U-shaped plate 23 and the round hole block 13. The brush 24 contacts the scraper 9 by repeatedly moving and fixing its position, so that the brush 24 cleans the scraper 9 by repeatedly moving up and down, thereby keeping the surface of the scraper 9 clean and preventing impurities from adhering to the surface of the scraper 9 and affecting the cleaning effect. It also prevents the scraper 9 from adsorbing waste and causing blockage when scraping waste, which affects the scraping effect on the extrusion die 1.

[0025] Reference Figure 4 As shown, in this embodiment, the adjustment component includes: There are two connecting sleeves 26. One end of the connecting sleeve 26 is fixedly connected to the scraper 9, and the other end is fixedly connected to the plate 15. Both ends of the plate 15 are threadedly connected to a rotating rod 27. The other end of the rotating rod 27 is rotatably connected to the surface of the scraper 9. Through the two connecting sleeves 26, each of which is divided into two sliding rods of different sizes, they are interlocked for sliding and translation. The threaded connection between the rotating rod 27 and the plate 15 allows the connection between the rotating rod 27 and the scraper 9 to rotate. When the rotating rod 27 is turned and moved, it drives the scraper 9 to move closer to or away from the plate 15, thereby adjusting the distance between the scraper 9 and the plate 15. This allows the operator to adjust the position distance between the scraper 9 and the surface of the extrusion die 1 according to the actual usage, and avoids the contact gap between the scraper 9 and the extrusion die 1 being too large or too small, which would affect the cleaning effect of the scraper 9.

[0026] Reference Figure 3 and Figure 4 As shown in this embodiment: an arc-shaped plate 25 is fixedly connected to the surface of the scraper 9. The arc-shaped plate 25 has an arc structure. By setting the arc-shaped plate 25 on the surface of the scraper 9, when the scraper 9 scrapes off the waste, if the waste is adsorbed on the surface of the scraper 9 and causes accumulation, or if the waste forms a long strip and moves along the surface of the scraper 9 when it is scraped off, the arc-shaped plate 25 can form a blockage against the waste. Moreover, its arc structure can guide the waste to move forward, preventing the waste from moving along the surface of the scraper 9 into the gap between the scraper 9 and the flat plate 15. At the same time, the arc structure can guide the waste to form a bend, breaking the waste and preventing the waste from forming a long strip after being scraped off and connecting with the unscraped waste, so that the waste cannot fall down after being scraped off from the surface of the extrusion die 1.

[0027] Working principle: When impurities or solidified waste are adsorbed on the bottom and sides of the extrusion die 1 due to the hot melt material of the flowing film during actual use, the operator controls the motor 6 through the control computer 4. The motor 6 drives the lead screw 7 to rotate. Through the threaded connection between the lead screw 7 and the sleeve 8, and the sleeve 8 being connected to the connecting rod 11 and the shaft 21, it will not rotate. This allows the sleeve 8 to move back and forth along the surface of the lead screw 7. At the same time, it drives the circular hole block 13 and the sliding plate 14, causing the scraper 9 to move against the surface of the extrusion die 1. The scraper 19 and the extension plate 10 also move with the circular hole block 13. The scraper 19 adheres to the bottom of the extrusion die 1, and the scraper 9 scrapes the waste off the surface of the extrusion die 1. The sliding plate 14 is sleeved on the outside of the inclined plate 17 and slides. When the sliding column 16 moves horizontally, it slides in the wave groove 18. Through the wave trajectory of the wave groove 18, the sliding column 1... The surface of the 6 will adhere to the inner wall of the wave groove 18 and move along the wave trajectory of the wave groove 18. At this time, the sliding column 16 will move up and down repeatedly on the inner wall of the wave groove 18, and at the same time move horizontally. Through the sliding connection between the sliding plate 14 and the round hole block 13, the sliding column 16 moves up and down repeatedly, driving the sliding plate 14 to move up and down repeatedly inside the round hole block 13, and driving the scraper 9 to move up and down repeatedly. When the scraper 9 moves horizontally to scrape off the waste, it will adhere to the surface of the extrusion die head 1 and move up and down repeatedly. Through the repeated movement of the scraper 9, the waste is scraped horizontally on the surface of the extrusion die head 1 and vibrates and moves horizontally, improving the scraping effect of stubborn waste. The waste stuck to the scraper 9 is shaken off by the repeated movement of the scraper 9. After cleaning is completed, the motor 6 drives the lead screw 7 in the opposite direction to drive the sleeve 8 to reset the scraper 9, in preparation for the next waste scraping work. During the cleaning process, the sleeve 8 moves horizontally, driving the connecting rod 11 to pull the shaft 21, which in turn drives the rotating rod 20 to move along the inner diameter of the irregular groove plate 22. The rotating rod 20 slides to one end of the irregular groove plate 22. Through the arc structure at one end of the irregular groove plate 22, when the rotating rod 20 moves to the arc, one rotating rod 20 will gradually enter the arc along the inner diameter of the irregular groove plate 22. At this time, the other one is still placed at the horizontal position of the inner wall of the irregular groove plate 22. At this time, one rotating rod 20 will rotate downward along the arc of the irregular groove plate 22, thereby driving one end of the waste tray 12 to rotate downward with the other rotating rod 20 as the center. This causes the waste tray 12 to deflect and tilt at a certain angle. At this time, the waste collected inside the waste tray 12 slides to one side along the arc structure of the waste tray 12, so that the waste is poured out from inside the waste tray 12 when the waste tray 12 is tilted. When the scraper 9 moves up and down repeatedly and moves to one side, the fixed connection between the U-shaped plate 23 and the round hole block 13 allows the brush 24 to stick to the surface of the scraper 9 and move along with the scraper 9. This facilitates the contact between the scraper 9 and the fixed position of the brush 24, so that the brush 24 can clean the scraper 9 by moving up and down repeatedly. The connection between the rotating rod 27 and the scraper 9 can be rotated, and when the rotating rod 27 is turned and moved, the scraper 9 is driven to move closer to or away from the plate 15, thereby realizing the adjustment of the distance between the scraper 9 and the plate 15, so that the operator can adjust the position distance between the scraper 9 and the surface of the extrusion die 1 according to the actual use.

[0028] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
