Description

Technical Field

[0001] The utility model relates to the field of PVC layering strip production, in particular to a mixing device for PVC layering strip production. Background Art

[0002] At present, a Chinese utility model with the announcement number CN204699623U discloses a PVC material mixing device, which includes a body, and the body includes a feed port, a variable frequency motor, a first stirring shaft and a second stirring shaft. The outer wall of the body is provided with multiple feed ports; a fan is provided above the body; a gas pre-distributor is provided at the top position inside the body; a partition is provided at the center position inside the body; the top of the partition is connected to the fan; a layer of air flow equalizing plate is provided on the surface of the partition; a base is provided below the body; a variable frequency motor is provided between the body and the base; the output part of the variable frequency motor is connected to a reducer; the output part of the reducer is respectively connected to the first stirring shaft and the second stirring shaft; the surface of the first stirring shaft and the second stirring shaft is provided with a horizontal stirring shaft. The utility model has the advantages of reasonable structural design, good stirring effect and convenient use.

[0003] The existing mixing device cannot replace the stirring rod. During the mixing process of PVC raw materials, the rotating shaft drives the stirring rod to rotate to continuously stir and mix the PVC raw materials. After a long period of stirring and mixing, the stirring rod becomes seriously worn, affecting the stirring and mixing efficiency. In the prior art, the stirring rod is generally connected to the rotating shaft by welding, and usually the rotating shaft and the stirring rod are completely replaced, which increases the maintenance cost and reduces the practicality. It is also impossible to adjust the discharging speed and quantitative discharging. When discharging, the discharging speed of the general mixing device is difficult to control. When discharging, the discharging speed is sometimes fast and sometimes slow, which easily causes the raw materials to scatter. The discharging amount is determined according to human experience and requires manual control. The control accuracy is low and it is not convenient to use. In order to solve the above-mentioned problems, we propose a mixing device for PVC strip production. Utility Model Content
