Powder coating crushing device with cooling function

Abstract

The invention provides a powder coating crushing device with the cooling function. The powder coating crushing device comprises a crushing box, a feeding device, a discharging port and a supporting part at the bottom of the crushing box; the position below the feeding device is provided with a first crushing area, the first crushing area comprises a vertical shell, a material filter plate and a rotating body, a first crushing cutter is arranged on the vertical shell, the bottom of the vertical shell is connected with a rotary shaft, a second crushing cutter is arranged on the rotating body, the rotary shaft and the bottom of the rotating body are connected with a motor, a first level crushing area and a second level crushing area are formed between the inner side wall of the crushing box and the outer side wall of the vertical shell, a first crushing cavity is formed under the secondary crushing area, a funnel-shaped second crushing cavity is formed under the first crushing cavity, thefunnel-shaped second crushing cavity is connected with a discharging port, a Peltier element is attached to the outer side wall of the crushing box, a temperature detector is arranged on the rotatingbody, and the temperature detector is electrically connected with the Peltier element. The powder coating crushing device cannot only achieve multi-level crushing of the powder coating to make the powder coating reach the expected grain size quickly, but also can timely absorb the heat generated by the powder coating in the crushing and cutting process.

Description

technical field [0001] The invention relates to the technical field of pulverizers, in particular to a powder coating pulverization device with a cooling function. Background technique [0002] Powder coating is a new type of solvent-free 100% solid powder coating, which has the characteristics of no solvent, no pollution, recyclable, environmental protection, saving energy and resources, reducing labor intensity and high mechanical strength of the coating film. The current powder coating crushing device generally crushes the raw materials directly. During the crushing process, it is not only easy to cause incomplete crushing, but also because the size of the raw materials is large, the load on the crushing machine is relatively large, and the machine is easy to be damaged. At the same time, during the crushing process, due to the high-speed cutting friction between the crushing tool and the powder coating, the overall temperature of the powder coating will increase, thereby...

Problems solved by technology

The current powder coating crushing device generally crushes the raw materials directly. During the crushing process, it is not only easy to cause incomplete crushing, but also because the size of the raw materials is large, the load on the crushing machine is large, and it is easy to damage the machine.

At the same time, during the crushing process, due to the high-speed cutting friction between the crushing tool and the powder coating, the overall temperature of the powder coating will increase, thereby affecting the physical and chemical properties of the powder coating.
