Description

Technical Field

[0001] The utility model relates to the technical field of drying devices, in particular to a vertical multi-layer drying device of a coating machine. Background Art

[0002] Coating machines are mainly used for surface coating production of films, papers, etc. This machine coats the rolled substrate with a layer of glue, coating or ink with specific functions, and cuts it into sheets or rolls it up after drying. It uses a special multi-functional coating head and can achieve various forms of surface pattern generation. The reel and unreel of the coating machine are equipped with full-speed automatic film splicing mechanism and PLC program tension closed-loop automatic control. During the drying process of the coating machine, a vertical multi-layer drying device is usually used to dry the substrate.

[0003] In the prior art, the vertical multi-layer drying device needs to use the electric heating plate for a long time, resulting in a short service life of the electric heating plate, and needs to be replaced frequently. However, the existing electric heating plate is troublesome to replace, and the existing drying device does not have the function of filtering dust. Dust entering the inside of the drying device will not only further shorten the service life of the electric heating plate, but also adhere to the surface of the undried substrate, causing the quality of the substrate to decrease. During the drying process, the undried paint will produce toxic gases, water vapor, etc. after being heated, and the gas escape will cause harm to the operator's body. Therefore, in view of the above problems, a vertical multi-layer drying device for a coating machine is proposed. Utility Model Content

When the electric heating plate needs to be replaced, the baffle is pushed, and the baffle drives the limiting rod and the first clamping block to move, the reset spring is compressed, the first clamping block and the second clamping block are separated, and then the filter plate is turned over, the bolt is screwed out from the inner side of the threaded groove and taken out from the inner side of the round hole, and the electric heating plate can be taken out, and then a new electric heating plate is replaced, and the new electric heating plate is put into the inner side of the fixing frame so that the threaded groove Align with the round hole, insert the bolt into the inner side of the round hole and screw it into the inner side of the threaded groove, then push the baffle, the baffle drives the limit rod and the first clamping block to move, the reset spring is compressed, the filter plate is turned over and the baffle is loosened, the reset spring resets and drives the first clamping block and the second clamping block to be connected, and the installation of the electric heating plate is completed. Before use, power on the equipment, start the electric heating plate and the fan, insert the substrate into the through groove on one side of the drying box body, wrap it around the outside of the roller and take it out from the through groove on the other side of the drying box body. At this time, the fan brings the outside air into the inside of the fixed frame through the filter plate, the filter plate isolates the dust from the outside, and the cold air enters the inside of the drying box body after being heated by the electric heating plate to dry the substrate;

[0013] 2. In the utility model, the toxic gas generated inside the drying box body can be purified by the provided fixed cylinder, fixed ring, drying plate, activated carbon plate, exhaust gas purification plate, fixed ring, bearing, screw and cylinder cover to prevent the escape of toxic gas. Before use, the drying plate, activated carbon plate and exhaust gas purification plate are placed into the top of the fixed ring inside the fixed cylinder according to needs, and then the cylinder cover is screwed on the top of the fixed cylinder, and the screw is rotated. Due to the limitation of the cylinder cover and the bearing, the screw drives the fixed ring to descend until the fixed ring presses the drying plate, activated carbon plate and exhaust gas purification plate. When the drying box body is used, the gas generated inside the drying box body escapes through the fixed cylinder, and the drying plate and activated carbon plate can absorb water vapor in the gas to prevent the water vapor from causing moisture to the substrate and reducing the quality of the substrate. The exhaust gas purification plate can absorb toxic gas to prevent the escape of toxic gas from causing harm to the operator. BRIEF DESCRIPTION OF THE DRAWINGS
