Description
Technical Field
The invention relates to a silver paste filtering device, in particular to a silver paste filtering device for a resistor of a conductive plastic potentiometer.
Background
The silver paste is one of important raw materials of the resistor body for the conductive plastic potentiometer, and the viscosity and the granularity of the silver paste can directly influence the quality of the resistor body, so that the quality of the conductive plastic potentiometer is influenced. Therefore, before the resistor is produced, the silver paste needs to be filtered, so that the granularity of the silver paste is ensured to meet the requirement. Because the viscosity of the silver paste is high, the silver paste is difficult to filter under the condition of no external force intervention.
The traditional technology usually adopts the form of manual scraper blade to filter, is about to add right amount of silver thick liquids to the screen with suitable mesh, utilizes the scraper blade laminating to carry out reciprocal scraping work on the screen again by the manual work, impels the silver thick liquids that the granularity is suitable to pass through the screen and drips in the container. The filtering mode has low efficiency, and the silk screen is easy to damage due to uneven force application of workers, so that the granularity of the silver paste is difficult to ensure.
The traditional filter equipment of general electronic paste generally adopts the motor drive scraper blade rotation to realize filtering purpose, nevertheless all adopts the more thick liquids of splendid attire in the storage bucket and arranges the scraper blade structure in the storage bucket, still is equipped with rabbling mechanism in order to improve the filter effect generally in the storage bucket.
For example, the utility model patent of patent number "ZL 201420643796.8", disclose an electronic paste filter equipment, with synchronous machine as the aircraft nose of main drive ware, use the ball screw elevating system that is driven by the motor to pull the high accuracy slider of installing on the stand and drive the aircraft nose as aircraft nose elevating system, the polyurethane scraper blade passes through anchor clamps and installs rotary motion on the main shaft, use circular screen frame as filtering the half tone and install in the middle part that connects storage bucket and filter vat, when the scraper blade is rotatory and exert certain pressure for filtering the half tone, the electronic paste of high viscosity in the filter vat is because the pressure of scraper blade, the gap from the silk screen is extruded, flow in connects in the storage bucket, the scraper blade lasts rotatoryly, realize continuous filtration, the impurity of large granule is owing to can not pass through the gap of silk screen, stayed in the filter vat, thereby realize filterable mesh.
For another example, the utility model patent with the patent number "ZL 201920954359.0" discloses an intelligent slurry filtering device for lithium battery production, which comprises a filter box, a feeding hopper, a stirring motor, a stirring pipe, a transverse stirring frame, a large-aperture filter screen plate, a positioning hole, an auxiliary filtering and extruding frame structure, an auxiliary crushing frame structure, a detachable material frame structure, a fine-aperture screen plate, a discharging hopper, a supporting leg, a discharging pipe, a discharging valve, a controller and a regulating switch, wherein the feeding hopper is inserted at the left side and the right side of the upper part of the filter box; the stirring motor is arranged at the middle upper part of the filter box through a bolt; the stirring pipe is arranged on the inner side of the re-filtering box and is connected to the lower output shaft of the stirring motor at the upper end through a key.
Above-mentioned traditional electronic paste filter equipment, its scraper blade all arrange in be used for splendid attire thick liquids the filter vat or the rose box in, because the thick liquids are more, so even there is rabbling mechanism also to be difficult to realize smooth filter effect, to the silver thick liquids that the viscosity is higher, above-mentioned device more can't realize effective filtration. Simultaneously, because need undertake great gravity, so install the filter screen of installing in filter vat or rose box bottom and need adopt stereoplasm mesh, or adopt stereoplasm support and silk screen, all need fixed mounting, difficult quick replacement filter screen or silk screen as required like this, also can influence the filter effect if have the stereoplasm support below the silk screen moreover to filter effect and efficiency have been reduced.
