For example, Chinese Patent Publication No. CN212422254U discloses an automated production line for PVC processing, which suffers from uneven material mixing, poor plasticizing effect, difficulty in removing impurities, easy deformation of film during cooling, inflexible adjustment of production parameters, and inability to accurately measure film length. This results in low production efficiency, unstable product quality, and difficulty in meeting the market demand for high-quality PVC calendered film. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an integrated production line device for PVC calendered film processing and packaging. By optimizing each link of the processing line, the problems in the prior art are effectively solved, and efficient and high-quality continuous production of PVC calendered film is realized.

[0004] The technical solution adopted in this utility model is as follows: An integrated production line for PVC calendered film processing and packaging includes the following components arranged in sequence: The pellet mixing and feeding machine is used for mixing and lifting PVC pellets and additives. It includes a mixing silo and an elevator. The mixing silo stores PVC pellets and additives. One end of the elevator is located at the bottom of the mixing silo, and the other end is connected to the top of the planetary extruder. Planetary extruders are used for plasticizing mixed materials. They include a feeding hopper and a planetary screw. The feeding hopper is located at the output end of the elevator. The material enters the gap between the thread teeth of the planetary screw through the feeding hopper, melts, and is then extruded. A filter press is used to filter materials after extrusion, including a filter assembly located at the output end of a planetary extruder. The oscillating conveyor is used to uniformly transport materials to the four-roll calender. It includes a conveying channel and an oscillating seat. The conveying channel is driven by a conveying motor, and the oscillating seat is driven by an oscillating motor and oscillates relative to the four-roll calender within a range of 20°. A four-roll calendering machine used for the production of PVC calendered film includes four rolls arranged in an inverted L-shape. A cooling auxiliary machine is used for cooling PVC calendered film. It includes several horizontally arranged rollers and a cooling mechanism located below the rollers. The PVC calendered film is cooled and conveyed forward in a wave-like manner through the rollers. The cooling mechanism is connected to external cooling pipes. A three-roll surface winding machine is used to wind cooled PVC calendered film. It includes a winding mechanism and a cutting mechanism. The winding mechanism includes a roll for packing the PVC calendered film into a roll, and the cutting mechanism includes a cutter for cutting the PVC calendered film.

[0005] This technical solution optimizes various mechanisms in the processing line to achieve more efficient continuous production of PVC calendered film. Specifically, a granule mixing and feeding machine ensures thorough mixing and stable improvement of PVC granules and additives; a planetary extruder efficiently plasticizes the mixture, ensuring the material reaches a good melting state; a filter removes impurities from the plasticized material, improving product quality; a gyratory conveyor evenly transports the material to the four-roll calender, ensuring uniform calendered film thickness; the four-roll calender produces PVC calendered film that meets requirements; a cooling auxiliary machine evenly cools the film to prevent deformation; and a three-roll surface winding machine winds the cooled film into rolls for convenient storage and transportation.

Under the action of the stirring impeller, PVC granules and additives form a uniformly mixed material; the elevator is an inclined vacuum feeder.

[0007] This technical solution utilizes the rotating and stirring action of the impeller to fully mix PVC granules and additives in the hopper, forming a uniform material.

[0009] According to one embodiment of the present invention, the planetary extruder is a WE150 extruder with a metal separator at the bottom.

[0010] In this technical solution, a metal separator is installed at the bottom. Utilizing its magnetic field induction principle, it can detect and separate metal impurities mixed in with the material in time before the material enters the extruder, thus preventing metal impurities from entering the extruder and causing wear to key components such as the screw and barrel.

[0011] According to one embodiment of the present invention, the four-roll calendering machine includes a base, a transmission mechanism, rollers, a roller gap adjustment mechanism, and an axis cross adjustment mechanism.

[0018] Example 1 like Figure 1 and Figure 2 As shown, this embodiment provides an integrated production line device for PVC calendered film processing and packaging, comprising the following components arranged in sequence: Granule mixing and feeding machine 1 is used for mixing and lifting PVC granules and additives. It includes a mixing silo and an elevator. The mixing silo stores PVC granules and additives.

The winding mechanism includes a roll for packing the PVC calendered film into a roll, and the cutting mechanism includes a cutter for cutting the PVC calendered film.

[0019] like Figure 1 and Figure 2 As shown, this technical solution optimizes the various mechanisms of the processing line to achieve more efficient continuous production of PVC calendered film. Specifically, the granule mixing and feeding machine 1 achieves thorough mixing and stable improvement of PVC granules and additives; the planetary extruder 2 efficiently plasticizes the mixture to ensure the material reaches a good melting state; the filter 3 removes impurities from the plasticized material, improving product quality; the oscillating conveyor 4 evenly conveys the material to the four-roll calender 5 to ensure uniform calendered film thickness; the four-roll calender 5 produces PVC calendered film that meets the requirements; the cooling auxiliary machine 6 uniformly cools the film to prevent deformation; and the three-roll surface winding machine 7 winds the cooled film into rolls for convenient storage and transportation.

[0020] In addition, the PVC calendered film processing and packaging integrated production line device proposed above according to this utility model may also have the following additional technical features: According to one embodiment of the present invention, the mixing bin of the granular material mixing and feeding machine 1 is equipped with a stirring impeller. Under the action of the stirring impeller, PVC granules and additives form a uniformly mixed material; the elevator is an inclined vacuum feeder.

[0021] This technical solution utilizes the rotating and stirring action of the impeller to fully mix PVC granules and additives in the hopper, forming a uniform material. By setting the elevator as an inclined vacuum feeder, the negative pressure generated by the vacuum is used to quickly and stably lift the uniformly mixed material from the mixing hopper to the top of the planetary extruder 2.

[0022] According to one embodiment of the present invention, a platform is provided below the planetary extruder 2, and the height of the planetary extruder 2 is higher than that of the granule mixing and feeding machine 1; the planetary screw of the planetary extruder 2 includes a central screw and planetary small-diameter screws. The material is squeezed, rolled and sheared in the intermeshing and rotating screw teeth, and is continuously turned and mixed until it reaches a molten state. After the material is uniformly plasticized, it is gradually pushed to the front section of the planetary screw and extruded from the die head.

[0023] According to one embodiment of the present invention, the planetary extruder 2 is a WE150 extruder with a metal separator at the bottom.

[0024] In this technical solution, a metal separator is installed at the bottom. Utilizing its magnetic field induction principle, it can detect and separate metal impurities mixed in with the material in time before the material enters the extruder, thus preventing metal impurities from entering the extruder and causing wear to key components such as the screw and barrel.

[0025] According to one embodiment of the present invention, the four-roll calendering machine 5 includes a machine base, a transmission mechanism, rollers, a roller gap adjustment mechanism, and an axis cross adjustment mechanism.

The axis cross adjustment mechanism is located in the horizontal direction of the rollers and is used to adjust the spatial cross angle between the rollers.

[0026] According to one embodiment of the present invention, the three-roll surface winding machine 7 is equipped with a meter counter.

[0027] The usage process of the above embodiments is as follows: like Figure 1 and Figure 2As shown, during production line operation, PVC granules and additives are first stored in the mixing hopper of the granule mixing and feeding machine 1, where the rotating impeller ensures thorough mixing. An inclined vacuum feeder, using negative pressure, rapidly and stably lifts the mixture from the bottom of the hopper to the feeding hopper at the top of the planetary extruder 2. The material enters the planetary screw, where it is subjected to compression, rolling, and shearing within the meshing gap between the central screw and the smaller diameter planetary screws, continuously tumbling and mixing into a molten state. Simultaneously, a metal separator uses magnetic field induction to separate metal impurities. After being extruded through the die head of the planetary extruder 2, the molten material enters the filter 3, where the filter assembly removes impurities. Next, the conveying channel of the oscillating conveyor 4, driven by a motor, transports the material, and the oscillating seat, driven by the oscillating motor, is positioned relative to the four-roll calender main unit 5. The material is oscillated within a 20° range to ensure uniform material transport. The material enters the four-roll calender 5, and by adjusting the roller gap and shaft cross angle, a film meeting the requirements is produced. The film is then uniformly cooled and transported forward by the rollers of the cooling auxiliary machine 6 in a wave-like manner, with the cooling medium provided by the external pipeline of the cooling mechanism. Finally, the three-roll surface winding machine 7 winds the cooled film into a roll, the length is measured by a meter counter, and the cutter can cut it as needed.
