Powder coating screening and grinding device

Abstract

The invention discloses a powder coating screening and grinding device. The powder coating screening and grinding device comprises a machine shell, an anti-wind device, a screening plate A, a grindingmotor, a screw rod, a grinding roller and a vibration motor. The anti-wind device is fixedly mounted on a rotating shaft. The portion, inside a grinding cavity, of an output shaft of the grinding motor is connected with the screw rod. A sliding sleeve is in threaded connection to the screw rod. A connecting rack is fixedly connected to the lower side of the sliding sleeve. A rotating shaft is mounted on the connecting rack in a rotary manner. The grinding roller is fixedly mounted on the rotating shaft. A feeding opening is provided with the anti-wind device, powder backflow caused by ascending of internal airflow inside the screening cavity can be prevented, and human bodies can be prevented from being hurt by a coating while the site environment is prevented from being polluted; by means of the screening plate A, stage treatment of the powder coating is achieved, the grinding time is saved, and work efficiency is improved; and in the grinding process, the grinding motor rotates forwards and backwards to work, the screw rod is matched with the sliding sleeve, so that the grinding roller moves leftwards and rightwards on a screening plate B for grinding, and the grinding effect isimproved.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a powder coating screening and grinding device. Background technique [0002] Coating ingredients usually need to grind various raw materials into powder before production. Usually, this process is completed by existing ball mills or grinding equipment. When the existing grinding equipment is feeding powder, due to the upward wind force inside the device, the feeding The construction powder backflow causes the construction coating powder to scatter everywhere, which seriously affects the processing site environment. At the same time, during the grinding process, the existing device directly grinds the powder without classifying it, which greatly increases the grinding time and reduces the production efficiency. . Contents of the invention [0003] The object of the present invention is to provide a powder coating screening and grinding device to solve the problems raised in the above-m...
