Abstract

Technical Field
[0001] The utility model relates to the technical field of plastic particle processing, in particular to a plastic particle mixing device with a dust removal function. Background Art
[0002] Packaging films made of various materials such as PE, PVC, PP, etc. are usually made by the film blowing process. Film blowing is to heat and melt the plastic particles and then blow them to the required thickness through a high-pressure air pipe, and then form a film after cooling and shaping.
[0003] Plastic particles usually need to be modified by adding toughening agents, flame retardants, weathering agents and other substances, and then stirring and mixing. In existing stirring and mixing devices, such as the plastic particle modification and sufficient mixing device disclosed in patent CN220409281U, a motor drives the mixing shaft to rotate, thereby driving the first connecting rod and the stirring blade to start operating, thereby stirring the plastic particle raw material and the modified material to mix them.
[0004] During the mixing process of plastic particles and various additives, a large amount of dust will be generated due to collision and friction. The particle size of these dusts is extremely small, some of which are even less than 2μm. They can easily escape from the gaps in the maintenance door, inlet / outlet and other gaps of the mixing equipment. On the one hand, they will pollute the production workshop and production equipment. On the other hand, they will also be touched or inhaled by the staff, causing conjunctivitis, skin inflammation, pneumoconiosis and other diseases.
[0005] Therefore, the existing plastic particle stirring and mixing equipment needs to be improved. Utility Model Content
