Description

Technical Field

[0001] The present invention relates to the technical field of plastic film production, in particular to a plastic film extrusion molding device. Background Art

[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 extruders, die heads and other components. 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 adhere to certain waste materials due to the extrusion of hot-melt materials, causing the die head to be contaminated, thereby affecting the extrusion quality and production efficiency of the film.

[0003] In the existing plastic film production process, after long-term use of the die, its surface may absorb a certain amount of hot-melt waste and solidify to form adhesion. When the solidified waste is placed near the die outlet, the next time the die extrudes the finished film, the flowing film will come into contact with the waste near the die. The surface of the remaining waste is relatively hard and will absorb certain impurities. The waste will also come into contact with the extruded product. If the waste is not removed in time, it will cause serious quality impacts on the produced film, such as scratches, uneven thickness and contamination. These problems will not only reduce the appearance and quality of the film, but also increase the proportion of unqualified products, resulting in an increase in production costs. In addition, the long-term accumulation of waste may cause further damage to the die head, shorten the service life of the die head, and increase the company's maintenance costs. The outside of the die head will also be affected by the penetration of machine oil, causing oil stains to adhere to the surface of the die head. Therefore, how to effectively remove the waste on the die head has become a key issue in improving the quality and efficiency of plastic film production. Traditionally, waste cleaning is usually done manually, but since the waste is tightly adsorbed to the die head after solidification, it is difficult to remove. As a result, the die head needs to be cleaned frequently, and manual removal is inefficient, which not only consumes a lot of manpower and material resources, but also affects the normal production efficiency of the machine.

During the scraping process, the scraper 9 moves repeatedly to form vibrations, shakes off the waste adsorbed by itself, and improves its own translational scraping effect on the extrusion die 1, ensuring the efficiency and continuity of the cleaning process.

[0021] Reference Figures 1-5 As shown, in this embodiment: the scraping component includes: The circular hole block 13 is fixedly connected to the surface of the sleeve 8.

When the bottom and side of the extrusion die 1 are actually used and adsorb impurities or adhere to solidified waste due to the flow of film hot melt raw materials, the staff controls the motor through the control computer 4. 6 is running, so that the motor 6 drives the screw rod 7 to rotate, and the screw rod 7 is connected to the sleeve 8 through a thread, and the sleeve 8 is connected to the connecting rod 11 and the shaft 21 so that the sleeve 8 can move back and forth along the surface of the screw rod 7, and at the same time drives the circular hole block 13 and the sliding plate 14 to make the scraper 9 move close to the surface of the extrusion die 1, wherein the scraper 19 and the extension plate 10 will also move with the circular hole block 13, and the scraper 19 is in contact with the bottom of the extrusion die 1 and the scraper 9 to scrape the waste from the surface of the extrusion die 1, and the sliding plate 14 is sleeved on the outside of the inclined plate 17 to slide, and the sliding column 16 is used to slide in the wave groove 18 when it moves horizontally, and the wave trajectory of the wave groove 18 makes the surface of the sliding column 16 fit the inner wall of the wave groove 18 and the surface of the sliding column 16 fit the inner wall of the wave groove 18 and the surface of the sliding column 16 fits ... As the sliding column 16 moves along the wave trajectory of the wave groove 18, the sliding column 16 will be in a state of repeated up and down movement on the inner wall of the wave groove 18, and move horizontally at the same time. The sliding plate 14 is connected to the circular hole block 13 through the sliding connection, so that the sliding column 16 can drive the sliding plate 14 to move up and down repeatedly inside the circular hole block 13 when moving up and down, and drive the scraper 9 to move up and down repeatedly, so that the scraper 9 will fit the surface of the extrusion die 1 and move up and down repeatedly when scraping the waste in translation.

[0024] Referring to Figure 2 With Figure 3 As shown in the embodiment: the protection assembly comprises: The surface of the circular hole block 13 is fixedly connected with the U-shaped plate 23, one side of the U-shaped plate 23 is fixedly connected with the brush 24, the brush 24 is close to the surface of the scraper 9, when the scraper 9 repeatedly moves up and down and translates to one side, the fixed connection of the U-shaped plate 23 and the circular hole block 13 makes the brush 24 stick to the surface of the scraper 9 and move with the scraper 9, the repeated movement of the scraper 9 contacts the position-fixed brush 24, so that the brush 24 sweeps the scraper 9 up and down, thereby keeping the surface of the scraper 9 clean, avoiding the attachment of impurities on the surface of the scraper 9 to affect the cleaning effect, and further preventing the scraper 9 from being blocked by adsorbing waste when scraping the waste, thereby affecting the scraping effect of the extrusion die head 1.

[0025] Referring to Figure 4 As shown in the embodiment: the adjusting assembly comprises: There are two connecting sleeves 26, and one end of the connecting sleeve 26 is fixedly connected to the scraper 9, and the other end is fixedly connected to the flat plate 15. Both ends of the flat plate 15 are threadedly connected to a rotary rod 27, and the other end of the rotary rod 27 is rotatably connected to the surface of the scraper 9. Through the two connecting sleeves 26, each connecting sleeve 26 is divided into two sliding rods, one large and one small, which are arranged on each other for sliding translation, and then facilitate the threaded connection between the rotary rod 27 and the flat plate 15. The connection between the rotary rod 27 and the scraper 9 can be rotated and when the rotary rod 27 is twisted and moved, the scraper 9 is driven to follow the rotary rod 27 to approach or move away from the flat plate 15, thereby realizing the adjustment of the distance between the scraper 9 and the flat plate 15, so that the staff can adjust the position distance between the scraper 9 and the surface of the extrusion die 1 according to actual usage, to avoid the contact gap between the scraper 9 and the extrusion die 1 being too large or too small, affecting the cleaning effect of the scraper 9.

[0026] Reference Figure 3 and Figure 4 As shown, in this embodiment: the surface of the scraper 9 is fixedly connected with an arc plate 25, and the shape of the arc plate 25 is an arc structure. The arc plate 25 is arranged on the surface of the scraper 9. When the scraper 9 scrapes the waste, if the waste is adsorbed on the surface of the scraper 9 to cause accumulation, or the waste is scraped to form long strips and move along the surface of the scraper 9, the arc plate 25 can form a barrier to the waste, and through its arc structure, it can guide the waste to move forward, and prevent the waste from moving along the surface of the scraper 9 to the gap between the scraper 9 and the flat plate 15. At the same time, the arc structure can guide the waste to form twists and breaks the waste to prevent the waste from forming long strips after scraping and connecting with the unscraped waste, resulting in the waste being unable to fall down after being scraped from the surface of the extrusion die 1.

[0027] Working principle: When the bottom and side of the extrusion die 1 absorb impurities or adhere to solidified waste due to the flow of film hot melt raw materials in actual use, the staff controls the motor 6 through the control computer 4, so that the motor 6 drives the screw 7 to rotate, and the screw 7 is connected to the sleeve 8 through the threaded connection, and the sleeve 8 is connected with the connecting rod 11 and the shaft 21 and does not rotate, so that the sleeve 8 can move back and forth along the surface of the screw 7, and at the same time drives the circular hole block 13 and the sliding plate 14 to make the scraper 9 move along the surface of the extrusion die 1, wherein the scraper 19 and the extension plate 10 will also move with the circular hole block 13, and the scraper 19 is attached to the bottom of the extrusion die 1 and the scraper 9 to scrape the waste from the surface of the extrusion die 1, and the sliding plate 14 is sleeved on the outside of the inclined plate 17 to slide, and the sliding column 16 is used to slide in the wave groove 18 when it moves horizontally, and the wave trajectory of the wave groove 18 makes the sliding column 1 The surface of 6 will fit in the inner wall of the wave groove 18 and move along the wave trajectory of the wave groove 18. At this time, the slide column 16 will be in the up and down repeated movement on the inner wall of the wave groove 18, and move horizontally at the same time. Through the sliding connection between the sliding plate 14 and the circular hole block 13, the slide column 16 drives the sliding plate 14 to move up and down repeatedly inside the circular hole block 13 when moving up and down, and drives the scraper 9 to move up and down repeatedly, so that the scraper 9 will fit in the surface of the extrusion die head 1 and move up and down repeatedly when scraping waste. The scraper 9 moves repeatedly when it moves horizontally, forming a horizontal scraping waste on the surface of the extrusion die head 1 and vibrating and moving itself horizontally, thereby improving the scraping effect of stubborn waste, and through its own repeated movement, the waste adhered to the scraper 9 when scraping the material is shaken off. When cleaning is completed, the motor 6 drives the screw rod 7 in the reverse direction to drive the sleeve 8 to reset the scraper 9 to prepare for the next waste scraping work; During the cleaning process, the sleeve 8 moves horizontally to drive the connecting rod 11 to pull the shaft 21 to drive the rotating rod 20 to move along the inner diameter of the special-shaped groove plate 22, and the rotating rod 20 slides to one end of the special-shaped groove plate 22 through the arc structure at one end of the special-shaped 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 special-shaped groove plate 22. At this time, the other is still placed at the level of the inner wall of the special-shaped groove plate 22. At this time, one rotating rod 20 will rotate downward along the arc of the special-shaped groove plate 22, thereby driving one end of the waste tray 12 to rotate downward with the other rotating rod 20 as the center of the circle, so that the waste tray 12 itself deflects and tilts at a certain angle. At this time, the waste collected in 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 the inside of the waste tray 12 when the waste tray 12 tilts; When the scraper 9 moves up and down repeatedly and translates to one side, the U-shaped plate 23 is fixedly connected to the circular hole block 13, so that the brush 24 is attached to the surface of the scraper 9 and moves along with the scraper 9, which facilitates the repeated movement of the scraper 9 and the contact with the fixed position brush 24, so that the brush 24 cleans the repeatedly moving scraper 9 up and down; The connection between the rotary rod 27 and the scraper 9 can rotate and when the rotary rod 27 is twisted and moved, the scraper 9 is driven to follow the rotary rod 27 to move closer to or away from the flat plate 15, thereby adjusting the distance between the scraper 9 and the flat plate 15, so that the staff can adjust the position distance between the scraper 9 and the surface of the extrusion die head 1 according to actual usage.
