Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of automobile plastic parts production, more specifically, it relates to a plastic mixing machine for automobile plastic parts production. BACKGROUND
[0002] In the field of automobile plastic parts production, the existing plastic mixing machine has many technical defects in the actual application process, which seriously affects the production efficiency and product quality, mainly in the following aspects:
[0003] Firstly, the existing mixing machine faces serious electrostatic adhesion problems in the discharging link, as the plastic particles produce static electricity during stirring, resulting in a large amount of material firmly adsorbed on the inner wall of the mixing tank. This phenomenon not only causes waste of raw materials and reduces actual output rate, but also makes it difficult to remove these electrostatically adsorbed materials, which requires a lot of time and effort for manual cleaning. This time-consuming and laborious cleaning process not only increases production costs, but also prolongs the downtime of the equipment, seriously affecting the continuous operation efficiency of the production line, especially in large-scale production scenarios, the frequent cleaning work greatly reduces the overall production efficiency.
[0004] Secondly, in view of the above problems, although some improved devices introduce rapid discharging devices and high-pressure gas cleaning systems to try to solve the material adhesion problem, these improvements have brought new technical risks. Specifically, the automatic opening and closing device of the discharging mechanism has reliability problems, which can easily open accidentally during equipment operation. This fault not only causes the premature discharge of incompletely mixed materials, affecting product quality, but also may cause material leakage, resulting in raw material waste and environmental pollution. More seriously, this accidental opening may force the entire production process to be interrupted, requiring reprocessing of materials, which greatly reduces production efficiency.
[0005] More importantly, the stirring mechanism design of the existing mixing machine has obvious defects. Most devices use a simple structure of a single stirring frame. This design causes a stable annular vortex to form in the mixing tank during actual operation. This vortex effect causes the material to tend to move in a fixed path, seriously affecting the full exchange and mixing of materials between different areas. Specifically, the materials in the center and edge areas of the tank body are difficult to exchange effectively, resulting in uneven mixing; the directional movement of materials in the stable vortex reduces the opportunity for random collision, reducing mixing efficiency; some areas may form "dead corners" and mixing dead zones. These problems not only prolong the mixing time, but also may affect the quality uniformity of the final product. INVENTION CONTENTS
