Description

Technical Field

[0001] The invention relates to the technical field of mixers, in particular to a mixer for plastic processing. Background Art

[0002] Plastic processing mixers play a vital role in the production process of plastic products. They are mainly used to evenly mix plastic raw materials and additives to ensure the quality and performance of the final product. However, existing plastic processing mixers have some obvious deficiencies in design and function, especially the design of the stirring blades is limited to the stirring function but not the cleaning function, which not only increases the maintenance cost in the production process, but also affects the service life and working efficiency of the equipment.

[0003] The stirring blades of existing plastic processing mixers only have a stirring function, but not a cleaning function. During the plastic processing process, the stirring blades need to contact plastic particles or powders for a long time, which easily leaves residues on the surface of the blades. These residues not only affect the uniformity of the material during the next stirring, but may also cause cross-contamination, especially when different types of plastic raw materials or colors need to be replaced. In addition, the residues adhere to the stirring blades for a long time, gradually harden, and are difficult to remove, which not only increases the difficulty of cleaning, but may also cause damage to the stirring blades, affecting the overall performance of the mixer.

[0004] Existing mixers for plastic processing do not have a cleaning function, resulting in a large maintenance workload and low efficiency. In actual production, in order to ensure product quality, the mixer needs to be thoroughly cleaned before and after each use. However, due to the lack of effective cleaning design of the mixer itself, operators often need to manually disassemble the mixing blades, use brushes, scrapers and other tools to clean them, and then reassemble them. This process is not only time-consuming and labor-intensive, but also prone to equipment damage due to improper operation. More importantly, frequent manual disassembly and assembly not only increases the labor intensity of workers, but may also cause the equipment's sealing to decrease due to irregular disassembly and assembly, affecting the mixing effect.

[0005] Agitators that lack automatic cleaning functions also pose hidden dangers in terms of hygiene and safety. In the plastic processing industry, sanitary conditions are crucial to product quality. If the mixer is not cleaned promptly and effectively, the residue may breed bacteria or mold, contaminating the plastic products produced subsequently. In addition, during manual cleaning, operators need to directly contact the mixing blades, which may cause cuts or pinching. This puts higher demands on the company's safe production management and increases the complexity and cost of safety management.

[0006] A mixer without automatic cleaning function will also affect production efficiency and the economic benefits of the enterprise. In the actual production process, due to the need to spend a lot of time on manual cleaning, the effective working time of the equipment is shortened and the production efficiency is reduced. This impact is especially significant in the case of continuous production or large-volume orders. In addition, frequent shutdowns for cleaning not only affect the continuity of the production line, but may also cause delivery delays, causing economic losses to the company.

[0007] Therefore, how to provide a mixer for plastic processing is a problem that those skilled in the art need to solve urgently. Summary of the invention
