Drum-type coating machine with automatic on-site cleaning device

Abstract

The invention relates to a drum-type coating machine with an automatic on-site cleaning device, which comprises a host machine and a microcomputer control system, wherein the host machine comprises a coating drum, a drum main shaft and an automatic cleaning device; a cleaning fluid output manifold of the automatic cleaning device is connected with a second cleaning fluid input manifold installed on the box body of the host machine; the second cleaning fluid input manifold is provided with a plurality of cleaning fluid output branch pipes, wherein a first cleaning fluid output branch pipe is connected with a drum cleaning fluid input pipe passing through the drum main shaft, and a second cleaning fluid output branch pipe is arranged outside the coating drum and a working chamber of the coating machine; and the cleaning working state is controlled by the microcomputer control system. By adopting the technical scheme, the inside and outside of the drum of the coating machine and the working chamber of the host machine can be automatically cleaned, and the coating machine is simple in operation and is convenient in use.

Description

technical field [0001] The present invention relates to a drum-type coating machine, in particular to a drum-type coating machine with an automatic cleaning device, which is mainly suitable for the inside and outside of the coating drum and the working room of the main engine after the drum-type coating machine is produced and discharged. The in-place automatic cleaning and drying. Background technique [0002] The drum coating machine is mainly composed of main engine, hot air blower, exhaust fan, atomization system and microcomputer automatic control system and other components. The coated tablets and pill cores move in a clean and airtight rotating drum under the action of the streamlined deflectors, and the coating medium is automatically sprayed according to the process flow and parameters during the movement. At the same time, hot air is supplied under negative pressure, so that the coating medium sprayed on the surface of Su Rui can be dried quickly and evenly, formi...

Problems solved by technology

Manual cleaning is very troublesome, it will consume a lot of manpower, and it is difficult to guarantee the cleaning requirements by manual cleaning. Cleaning verification must be done after each cleaning

When cleaning the mobile semi-automatic cleaning device, first move the cleaning device to the vicinity of the coating machine, and then connect all the cleaning hoses, especially to clean the inside of the coating drum. The hoses must pass through the operation in front of the coating machine. The door enters the drum. Since the coating drum is rotating during cleaning, the seal between the operation door and the drum mouth is difficult to solve, and the cleaning pipeline must be disassembled every time for cleaning. The cleaning liquid is leaked in the production site during cleaning. Hot water cleaning, the leakage of the cleaning pipeline will also bring unsafety to the operators, increase the difficulty of management and the cost of cleaning
