The invention aims to solve the problems that in the prior art, most of metal silk screens in screen printing adopt a contact type cleaning method, mesh holes and structures of the metal silk screens are easy to damage, and manufacturing of printing plates is influenced, and provides a metal silk screen cleaning system for screen printing.
In order to achieve the purpose, the invention adopts the following technical scheme: a metal wire mesh cleaning system for screen printing comprises a cleaning box, wherein a cleaning cavity is formed in the cleaning box and is divided into a fixing space and a liquid storage space which are communicated with each other, the diameter of the fixing space is larger than that of the liquid storage space, a heating plate is fixedly connected to the inner wall of the bottom of the liquid storage space in an embedded mode, a plurality of thermocouples are fixedly connected to the heating plate, one ends, far away from the heating plate, of the thermocouples are communicated with the fixing space, a wire mesh plate abuts against the bottom of the fixing space, 10-15% hydrochloric acid solution is filled in the liquid storage space, a box cover is arranged at the top of the fixing space, two telescopic rods are fixedly connected to the bottom of the box cover, and a hydrophobic layer;
the wire mesh plate is obliquely matched, positioned and connected with the fixed space, the wire mesh plate is divided into a positioned square frame structure and a wire mesh structure which is fixed in the square frame structure in a sealing mode, the square frame structure of the wire mesh plate is abutted to the upper surface of the thermocouple, the hydrophobic layer is made of a super-hydrophobic material, the distance between the hydrophobic layer and the wire mesh structure of the wire mesh plate is set to be 1mm, a sewage channel is formed in the side wall of the cleaning direction, the sewage channel is communicated with the bottom of the inclined plane of the hydrophobic layer, the top of the cleaning box is connected with a cover plate, and the cover plate is connected with the cleaning box.
In the above-mentioned wire mesh cleaning system for screen printing, the drain has been seted up to the lateral wall of sewage passageway, drain department sealing connection has fixed stopper, the telescopic link adopts the hydraulic stem structure and controls its extension length through the temperature control piece.
Compared with the prior art, the invention has the advantages that:
1. according to the invention, the wire mesh plate is arranged in the fixed space, so that when cleaning solution in the liquid storage space below is heated and volatilized, the cleaning process of the metal wire mesh is realized in a steam cleaning mode, and the wire mesh cleaning device has the advantages that no cleaning liquid directly contacts the metal wire mesh in the whole process, and the problem that the structure of the metal wire mesh is influenced by physical cleaning is avoided;
2. when the cleaning liquid is used, the heating plate firstly heats the cleaning liquid, wherein the dilute sulphuric acid component has the characteristic of volatility greater than that of water, so that the dilute sulphuric acid component can volatilize in one step, and the thermocouple action simultaneously acts on two ends of the heating plate to respectively absorb heat and release heat for the two ends, and the heat absorption section is arranged at one end of the wire mesh plate, so that the wire mesh plate absorbs heat and cools, and an obvious temperature difference with the lower evaporating liquid is kept, and the cleaning liquid gas after volatilization or evaporation is rapidly cooled and liquefied when approaching the wire mesh plate, and is covered with a liquid layer on the surface of the wire mesh plate;
3. meanwhile, as the air pressure below the screen is continuously increased, the liquid drop layer on the lower surface of the screen is bent upwards singly under the action of the volatile gas to form bubbles under the action of the liquid tension, and at the moment, the bubbles generate large impact force after being broken to generate a vibration effect on the upper surface of the screen, so that the cleaning effect is improved;
4. when the temperature in the cleaning box rises to a certain degree by the heating plate, the telescopic rod is controlled by the temperature control sheet to move downwards, so that the water delivery layer of the super-hydrophobic material stops at a position 1mm above the wire mesh plate, and the position is smaller than the minimum thickness of the liquid drop, so that the liquid drop formed on the upper surface of the wire mesh continuously slides towards the lower end of the inclined surface under the drainage action of the super-hydrophobic material, and the bubble formed by the liquid below is rapidly broken after the surface of the super-hydrophobic layer is contacted, on one hand, the upper surface of the wire mesh structure is repeatedly cleaned in the same direction under the continuous drainage effect of the hydrophobic layer, and on the other hand, the cavitation cleaning effect is improved;
5. the hydrophobic layer is communicated with the sewage channel, so that the cleaned liquid drop part does not flow back to the cleaning box to cause secondary evaporation pollution, and can be discharged through the sewage outlet, and after the cleaning is finished, the heat release end of the thermocouple can be transferred to the wire mesh plate through reverse power transmission, so that the thermocouple can be quickly dried, and the thermocouple can be conveniently used continuously.
