Abstract

A screw pump filling device driven by a servo motor comprises the servo motor, a screw pump, a discharge pipe, a pneumatic filling valve, a filling nozzle, an electromagnetic flux reversing valve, an integrated circuit controller, a servo motor controller, an optoelectronic switch and a bottle to be filled, wherein a suction opening of the screw pump is communicated with a material box; a discharge opening is connected with the feeding end of the pneumatic filling valve through the discharge pipe; the filling nozzle is connected with the discharge end of the pneumatic filling valve; the pneumatic filling valve is controlled by the electromagnetic flux reversing valve; and the electromagnetic flux reversing valve is connected with an air source. The filling device has the advantages of simple structure, wide application range, reliable filling, low operation cost and high practicability. Furthermore, the practice showed that the screw pump filling device can accurately carry out the filling of high viscosity liquids and is particularly suitable for vertical multi-head filling.

Description

The screw pump filling device of driven by servomotor

Technical field:

The utility model relates to a kind of liquid-filling machine, relates in particular to the quantitative filling device of fat shape liquid.

Background technology:

In existing liquid vertical type bottle filler, usually adopt the principle of normal pressure gravity flow, solenoid control liquid valve opening and closing time, several filling elements by the solenoid control liquid valve are set below hopper, all filling elements all rotate with the liquid hopper in the course of the work, and the liquid-filling machine of this structure uses the history in existing nearly ten years at home.Can for liquid of vicidity or paste, because their cans under normal pressure or negative pressure state are difficult to reach accurate can requirement, for the As soon as possible Promising Policy customer requirements, people adopt the piston cylinder injection system to carry out can usually, as the promotion source, material is sucked by piston cylinder earlier and injects container to be filled then with cylinder, and this canning means must determine that piston cylinder can not aspirated air when the suction material, otherwise just metering is inaccurate, can't satisfy the can requirement.

The utility model content:

The purpose of this utility model provides a kind of screw pump filling device of driven by servomotor, and it can overcome the above-mentioned deficiency that existing bottle placer has.

The technical scheme that the utility model is taked is as follows:

The screw pump filling device of described driven by servomotor, it comprises servomotor 1, screw pump 2, discharge nozzle 3, pneumatic filling valve 4, can mouth 5, the logical change-over valve 6 of electromagnetism, integrated circuit controller 7, servomotor controller 8, photoelectric switch 10 and bottle 11 to be filled, the material sucking port 21 of screw pump 2 communicates with hopper 12, discharging opening 22 links to each other with the feed end of pneumatic filling valve 4 by discharge nozzle 3, can mouth 5 links to each other with the discharge end of pneumatic filling valve 4, pneumatic filling valve 4 is by logical change-over valve 6 controls of electromagnetism, and the logical change-over valve 6 of electromagnetism interlinks with source of the gas.

Further, the logical change-over valve 6 of electromagnetism interlinks by source of the gas bigeminy part 9 and source of the gas.

Its pouring process is as follows:

The liquid to be filled that has in the hopper 12 sucks by the material sucking port 21 of screw pump 2, be pressed into discharge nozzle 3 from discharging opening 22, inject bottle 11 to be filled by pneumatic filling valve 4 from can mouth 5 then, screw pump 2 is driven by servomotor 1, servomotor 1 is by integrated circuit controller 7 and servomotor controller 8 controls, pneumatic filling valve 4 is by logical change-over valve 6 controls of electromagnetism, and the logical change-over valve 6 of electromagnetism is by photoelectric switch 10 and integrated circuit controller 7 controls.

This filling apparatus is simple in structure, and Applicable scope is extensive, and can is reliable, and operating cost is low, and is practical.Use proof through reality, the utility model can accurately carry out the can of high viscosity liquid, is particularly suitable for the vertical multi-head can.
