Semi-automatic fixed-quantity filling equipment for liquid

Abstract

The invention discloses semi-automatic fixed-quantity filling equipment for liquid and belongs to filling equipment for liquid in cavities of heat dissipaters or drying racks. The semi-automatic fixed-quantity filling equipment is composed of a proportioned liquid storage container, a pressurization conveying pump, an electrical equipment control cabinet, a machine frame body, a flow division storage container, a fixed-quantitypre-filling solenoid valve, a fixed-quantitypre-filling container, a flow division filling control device, a filling control valve time controller, an inductive probe adjustment and ruler device, a product fixing frame, an electronic scale, a filling start switch, a fixed-quantityfilling start button, an infusion hose and a fixed baffle. The semi-automatic fixed-quantity filling equipment is simple and novel in structure, high in practicality, low in investment, low in labor intensity and high in filling efficiency and can be provided with a plurality of filling positions; the flow division filling control device is adopted, the highest filling speed is realized, the phenomenon that false filling or excessive filling occurs because air in cavities of products to be filled cannot be exhausted easily is avoided, and the product quality of the heat dissipaters is stable.

Description

technical field [0001] The invention belongs to the field of liquid quantitative distribution and filling, in particular to liquid filling equipment in the cavity of a radiator (or drying rack). Background technique [0002] Electric heating drying rack products need to be filled with different amounts of liquid in products of different specifications. When the liquid level is too high during the filling process, the internal pressure of the drying rack product is too high when it is heated, which may cause the product to burst, posing a safety hazard; When the position is too low, the surface of the product will be heated unevenly, which will affect the function of the product. Since there are only two threaded ports on the end face of the drying rack, when the filling flow is too large, the air in the drying rack cavity will not be easily discharged, and virtual filling will occur. Phenomena that affect product functions. At present, the existing liquid filling methods in...

Problems solved by technology

[0002] Electric heating drying rack products need to be filled with different amounts of liquid in products of different specifications. When the liquid level is too high during the filling process, the internal pressure of the drying rack product is too high when it is heated, which may cause the product to burst, posing a safety hazard; When the position is too low, the surface of the product will be heated unevenly, which will affect the function of the product. Since there are only two threaded ports on the end face of the drying rack, when the filling flow is too large, the air in the drying rack cavity will not be easily discharged, and virtual filling will occur. Phenomenon, affecting product function

At present, the liquid filling method in the cavity of the existing drying rack product is manual filling, and the manual filling method has defects such as low production capacity, high labor intensity, high production cost, prone to errors, and easy to cause energy waste.
