Pre-weighed reciprocating fluid weight output filling device

Abstract

The invention relates to a pre-weighed reciprocating fluid weight output filling device and belongs to a filling machine for a weighing method. A weighing tank I and a weighing tank II are arranged inparallel, and sensors are separately fixed to the bottoms of the weighing tank I and the weighing tank II; a large flow liquid inlet pipe A1 and a small flow liquid inlet pipe A2 connected to a feeding pipe a are connected to the weighing tank I through pipelines; a large flow liquid inlet pipe B1 and a small flow liquid inlet pipe B2 connected to the feeding pipe a are connected to the weighingtank II through pipelines; the bottom of the weighing tank I is connected to a large flow liquid outlet pipe A3 and a small flow liquid outlet pipe A4; the bottom of the weighing tank II is connectedto a large flow liquid outlet pipe B3 and a small flow liquid outlet pipe B4; and the large flow liquid outlet pipe A3, the small flow liquid outlet pipe A4, the large flow liquid outlet pipe B3 and the small flow liquid outlet pipe B4 are connected to a discharge pipe b. According to the pre-weighed reciprocating fluid weight output filling device, the two weighing tanks work alternately, so thatthe device can fill liquids continuously. By monitoring the weight of the fluids in the tanks by the weight sensors, the fluid weight is output precisely, and meanwhile, the pre-weighed reciprocatingfluid weight output filling device fills the liquids on a transport cart directly, so that the problem that it is labor- and time-wasting to fill the liquids in the prior art that the liquids are filled first and are loaded then is solved.

Description

technical field [0001] The invention belongs to a filling device using a weighing method, in particular to a pre-weighing reciprocating fluid weight output filling device. Background technique [0002] Filling refers to the operation of pouring liquid (or semi-fluid) into containers, which can be glass bottles, plastic bottles, metal cans, plastic hoses, plastic bags, etc. Existing fluid quantitative filling is mostly volumetric quantitative, as the publication number is CN107176316A, the name is a kind of quantitative fluid automatic filling production line, including support plate, first motor, ratchet, rotating plate, wedge, transmission gear, Conveying chains, placement boxes and injection tanks have complex structures; the other uses pistons to complete liquid delivery, but the delivery volume of each stroke of the piston is small, which is suitable for small container packaging, not suitable for large container filling. In addition, the above two volumes There are def...

Problems solved by technology

The above-mentioned filling method has the following defects: firstly, the staff needs to be highly concentrated to pay attention to the container filling weight at any time, otherwise it is very easy to overfill the fluid and cause the container to be overfilled; secondly, in order to prevent the overfilled container from flowing into In the market, it is usually necessary to re-inspect the filled liquid, and to invert the bottle for overfilled containers; again, after the filling is completed, the container needs to be moved out to the vehicle for transportation, which is time-consuming and laborious, especially for For large-weight containers (such as 200kg oil drums), manpower cannot do it, and mechanical devices are needed to assist in completing the loading
