Description

Technical Field

[0001] This utility model relates to the field of mixing equipment, and in particular to a mixing equipment for the production of polyester powder coatings. Background Technology

[0002] Currently, Chinese utility model patent CN206474050U discloses a paint mixing device. Although this device can use a moving mechanism to drive the mixing mechanism to mix the raw materials and water in the bucket, it still has other problems during use, such as slow mixing efficiency. Since the bucket is clamped and fixed after being placed in, it cannot rotate on its own. Therefore, the raw materials in the bucket can only be mixed by rotating the stirring rod in one direction. However, unidirectional rotation will reduce the fluid flow in the bucket and increase the mixing time. Moreover, it does not have an auxiliary defoaming function. A large number of bubbles will be generated during the mixing process. After the bubbles are formed, they will not only prolong the mixing time, but the air in the bubbles will also hinder the dispersion of the paint, affecting the uniformity and appearance of the final paint. Although the bubbles can disappear on their own by letting them stand, the waiting time is long, which reduces the production efficiency of the paint. In order to solve the above problems, we propose a mixing device for polyester powder coating production. Utility Model Content

[0013] By adopting the above technical solution, the ventilation effect inside the casing can be improved by setting up heat dissipation slots and dustproof nets, and dust can be prevented from falling in.

[0014] The present invention is further configured such that a first protective cover is bolted to the top of the base.

[0015] By adopting the above technical solution, the second motor can be protected by the first protective cover, preventing damage to the second motor from collisions with external objects.

[0016] The present invention is further configured such that the stirring rod is made of stainless steel.

[0017] Using the above technical solution, the stirring rod has the characteristics of high strength, low density and excellent corrosion resistance.

[0018] The present invention is further configured such that: a door panel is hinged to the front of the housing via a hinge, and a handle is welded to the front of the door panel.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. This utility model involves first pouring powdered raw materials and water into a material bucket, then simultaneously starting a first motor and a second motor. After starting, the first motor drives the stirring rod to rotate clockwise, while the second motor, through the cooperation of bearings, drives the second rotating rod to rotate. When the second rotating rod rotates, it drives the first rotating rod to rotate together through the transmission of the driving wheel, driven wheel, and belt. When the first rotating rod rotates, it drives the support frame and the material bucket to rotate counterclockwise. This improves the stirring efficiency of the equipment, and the bidirectional rotation improves the fluidity of the internal fluid, reducing the time required for paint production.

[0022] 2. This utility model features a starting cylinder. After starting, the cylinder drives the housing downwards. As the housing moves downwards, the amplitude transformer inserts into the material bucket and contacts the coating. Simultaneously, the ultrasonic generator, transducer, and amplitude transformer are activated. After starting, the ultrasonic generator provides a high-frequency AC signal to the transducer, which converts the electrical power into mechanical power, i.e., ultrasonic waves. The amplitude transformer amplifies the amplitude of the transducer and transmits it to the coating in the material bucket. This provides an auxiliary defoaming function, which can accelerate the elimination of bubbles generated during stirring, thus increasing the production efficiency of the coating and making it highly practical.
