Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing, in particular to a mixing device for preparing plastic films. Background Art

[0002] Films made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins are used for packaging and as coating layers. Plastic packaging and plastic packaging products occupy an increasingly large share in the market. When producing plastic films, solid resin raw materials need to be mixed with raw materials such as ethanol, ammonia water and deionized water.

[0003] In the prior art, Chinese patent publication number CN213860100U discloses a mixing device for preparing plastic film, including a heating and melting barrel, a support plate is fixedly installed on the top of the inner cavity of the heating and melting barrel, and a zigzag groove is opened on one side of the support plate. The mixing device for preparing plastic film drives the rotating plate to rotate by a motor as a drive. Since the rotating plate and the support plate are movably connected by a connecting rod, it is convenient to drive the connecting rod to rotate along the track of the zigzag groove when the rotating plate rotates. Since the connecting block on the connecting rod is movably connected to the auxiliary groove by a telescopic rod, the bottom of the driving frame is always facing downward, thereby driving the driving frame below the connecting block to move in a zigzag track, which is convenient for conveying the raw ingredients located in the middle of the heating and melting barrel to the inner wall of the heating and melting barrel, shortening the melting time of the raw ingredients, and also accelerating the efficiency of plastic film preparation.

[0004] However, when the utility model is actually used, the raw material particles are directly mixed with raw materials such as ethanol and ammonia water, and heated at the same time. The plastic raw material particles need to be melted while being mixed with other raw materials. After mixing, the raw material particles may not be melted thoroughly, affecting subsequent use. When heating the liquid ingredients, it takes a long time to heat up, which is not convenient for preheating the raw materials. Therefore, improvement is needed. Utility Model Content

[0015] By adopting the above technical solution, the support frame raises the height of the mixing barrel, which is convenient for material connection after discharging, and the connecting plate increases the stability of the support frame.

[0016] The utility model is further configured as follows: a bolt is threadedly connected to the bottom of the support frame, and the number of the support frames is two.

[0017] By adopting the above technical solution, the support frame and the ground are fixed by bolts to prevent the mixing barrel from shaking during mixing.
