Description

Technical Field

[0001] The utility model relates to the field of PVC strip production, and particularly relates to a raw material heating device for PVC strip production. Background Technique

[0002] At present, a Chinese utility model with the publication number of CN212123822U discloses a raw material heating device for PVC production, which relates to the technical field of PVC production equipment. The raw material heating device for PVC production includes a box body. A feed hole is opened on the upper surface of the box body, and a feed inlet is placed above the box body. In this raw material heating device for PVC production, through the cooperation between the first rotating motor and the driven wheel in the transmission box, when the driving wheel rotates, it can drive the driven wheel to rotate through the belt, so that the driven wheel can drive the cam to rotate, and then the cam can apply a downward pressure on the pressing plate. Through the cooperation between the telescopic spring under the pressing plate and the cam, the pressing rod can move up and down. Through the cooperation between the second rotating single machine under the pressing rod and the stirring rod, when the stirring rod rotates, it drives the stirring blades to rotate, effectively solving the problem that the existing raw material heating device heats the raw materials unevenly, seriously affecting PVC processing.

[0003] The existing heating devices have low heating efficiency. Generally, the positions of the heating mechanisms of the heating devices are fixed, and they can only heat the raw materials at one position and cooperate with the stirring mechanism to stir and heat them. Such a heating structure is difficult to quickly heat the raw materials evenly, resulting in a reduction in heating efficiency, affecting subsequent production, and reducing the production efficiency. They also do not have an anti-blocking function. Generally, the heating devices heat through the feed hopper. When feeding, due to the moisture of the materials and the narrow bottom of the feed hopper, it is very easy to cause feed blockage, and it is necessary to stop the machine to dredge it, affecting the production efficiency and increasing the workload. To solve the above problems, we propose a raw material heating device for PVC strip production. Content of the Utility Model
