Technical Field

[0001] This utility model mainly relates to the field of PVC film production, specifically to a high-toughness PVC film rubber open mixing mill. Background Technology

[0002] A film rubber open mixing mill (also known as an open mixing mill) is a key piece of equipment used for processing rubber and plastics (such as PVC). Its core function is to mix, plasticize, and press raw materials into films or sheets through mechanical shearing and thermoplasticization.

[0003] In the invention patent application CN202321904213.8, published on December 19, 2023, entitled "An Automatic Rubber Mixing Mill," the device includes a housing assembly. Support plates are disposed at the midpoint of both sides of the top of the housing assembly. Two rollers are connected between the top ends of the inner walls of the two support plates via bearings. Gears are disposed at one end of each roller, and driven wheels are disposed at the other end. A sliding rod is disposed between the midpoints of the inner walls of the two support plates. Two moving blocks are disposed outside the sliding rod. The device is equipped with control levers. One side of each of the two movable blocks is connected to one end of a connecting rod. The other end of each connecting rod is equipped with a knife holder. Blades are mounted on the outside of each knife holder. Two rollers are mounted between the bottom ends of the inner walls of the two support plates via bearings. A conveyor belt is mounted between the two rollers. This device, through the cooperation of the sliding rod, movable blocks, and connecting rods, enables the rubber open mill to cut and sheet the rubber after it has been opened during use. This significantly reduces the operating difficulty of the rubber open mill, improves its working efficiency, and reduces the workload of the workers.

[0004] During the operation of specific embodiments, the inventors discovered the following defects:

[0005] When the device is in operation, it cannot sieve the mixed materials. The existing rubber materials contain a lot of dust and impurities, which leads to defects on the surface of the finished PVC film. Utility Model Content

[0015] 3. Beneficial effects:

[0016] This utility model has a reasonable design. During the PVC film rubber open mixing operation, the rubber raw material is fed through the opening on the upper surface of the mixer. At this time, the impurity removal fan and telescopic cylinder in the screening structure are activated. On the one hand, the impurity removal fan blows out the dust and impurities in the poured rubber raw material through the blowout window. On the other hand, the rubber raw material on the surface of the granular screen plate is shaken by the telescopic cylinder, which does not affect the rubber raw material falling into the stirring and heating chamber for stirring and melting.

[0017] Simultaneously, the transmission motor drives the speed change device and the stirring wheel assembly to rotate the heating chamber inside, softening and stirring the rubber raw material. After melting, the solenoid valve opens, allowing the raw material to enter the pressure chamber for pressurization. The material is then discharged into the pressure chamber by turning on the motor on one side of the discharge plate. Attached Figure Description
