Coating device of medicine patch coating machine and using method of coating device

Abstract

The invention discloses a coating device of a medicine patch coating machine and a using method of the coating device. The coating device comprises a coating device upper machine body, one end of the coating device upper machine body is connected with a coating device spray head in a penetrating mode, one end of the coating device upper machine body is connected with a first raw material feeding pipe in a penetrating mode, one end of the coating device upper machine body is connected with a second raw material feeding pipe in a penetrating mode, and one end of the coating device upper machine body is connected with a third raw material feeding pipe in a penetrating mode. During coating, according to the size of base cloth, the extension lengths of the two sets of telescopic valve rods are controlled through two sets of telescopic motors so as to control the coating width of a coating nozzle, and therefore the coating device can adapt to coating work of medicine patches of different sizes and specifications; and the same or different raw material output pipes are connected to the first raw material feeding pipe, the second raw material feeding pipe and the third raw material feeding pipe, during coating, multiple different raw materials can be connected at the same time, and temporary mixing is carried out during coating work, so that the situation that coating cannot be carried out smoothly due to condensation caused by mixing in advance is prevented.

Description

technical field [0001] The invention relates to the technical field of coating machines, in particular to a coating device of a drug patch coating machine and a method for using the same. Background technique [0002] The coating machine is mainly used for the surface coating process production of film, paper, etc. This machine is to coat the rolled substrate with a layer of glue, paint or ink with specific functions, and then wind it up after drying. It uses a special The multi-functional coating head can realize various forms of surface coating production. The winding and unwinding of the coating machine is equipped with a full-speed automatic film splicing mechanism, and the PLC program tension closed-loop automatic control. [0003] The coating machine needs to use a coating device when it is in use. When the existing coating device is in use, when the size of the coating base cloth is different, it cannot conveniently adjust the size of the coating working surface, and ...
