Technical Field

[0001] This utility model relates to the technical field of adhesive production, and in particular to an airflow pulverizing device for an environmentally friendly epoxy resin adhesive production line. Background Technology

[0002] In the production process of environmentally friendly epoxy resin adhesives, some raw materials need to be crushed to facilitate subsequent mixing and processing. Due to the hot melting nature of adhesive raw materials, air jet mills are generally used for crushing.

[0003] Existing airflow pulverizing devices, such as the airflow pulverizer with adjustable fineness disclosed in utility model patent application number 202323616073.7, mainly include a device housing. The lower end of the device housing is provided with a load-bearing plate, and the top of the load-bearing plate is provided with a vibration component. One end of the rotating shaft is provided with a rotating rod, and a connecting block is fixedly installed on the outer wall of the rotating rod. A limiting block is sleeved on the outer wall of the connecting block, and connecting rods are provided at both ends of the limiting block. The other end of the connecting rod is fixedly installed on the outer wall of a connecting plate, and a positioning rod is installed on the inner wall of the connecting plate. A positioning block is fixedly installed at one end of the positioning rod. In use, the rotation of the rotating shaft drives the connecting block to swing left and right, which in turn drives the connecting rod to swing. The swing of the connecting rod drives the positioning block to swing left and right, thereby causing multiple sets of positioning blocks to swing left and right on the outer wall of the device housing and strike the outer wall of the device housing.

[0004] However, existing air jet mills often require replacing the classifier impeller when adjusting the output fineness, which is very troublesome. After long-term use, the material can easily clog the fan impeller, affecting the output rate. Moreover, most existing air jet mills directly deliver compressed air into the device, which can easily lead to unstable air pressure and affect the grinding effect. Utility Model Content

This device not only allows for rapid adjustment of the fineness of the material passing through, avoiding material blockage and improving the flexibility of the device, but also utilizes an air chamber to ensure the stability of the conveying air pressure, thereby enhancing the pulverizing effect.
