Abstract

The utility model relates to a drip-proof device of a liquid filling machine, in particular to the drip-proof device of the liquid filling machine for measuring the capacity of a piston type metering pump. The utility model is suitable to the liquid filling machine of the medicine industry, the chemical industry, the light industry, and the food industry; a mesh screen installed on the end surface of the injector torch of a piston type liquid filling machine by the utility model is arranged in an injecting nozzle, and the purpose of the drip proof and the prevention of the pollution are realized; besides, the production is increased, and the goal of guaranteeing the quality is realizedThe utility model has the advantages of simple structure, low cost, easy fabrication and convenient operation.

Description

Leakageproof unit of liquid pouring machine

The utility model is a kind of liquid-filling machine antidrip device, particularly a kind of plunger type pump carries out the antidrip device of the liquid-filling machine of capacity measurement, be applicable on the filling liquid machinery of industries such as medicine, chemical industry, light industry, food, be specially adapted to filling liquid machineries such as agricultural chemicals, chemical reagent, prevent water clock, improve output, reduce and pollute.

The plunger tpe liquid-filling machine of prior art for the less material of surface tension, as agricultural chemicals, chemical reagent etc., for preventing water clock, generally adopts the less nozzle of caliber.Because the caliber of nozzle is little, when can such as speed higher, then impact and seethe severity, very easily go out bottleneck, influenced the standard of metering, thus the production efficiency when having reduced filling liquid, if adopt big caliber nozzle, then weeping is difficult to again avoid.If fluid drips on bottleneck or body, will influence packaging quality, medicine can cause that vessel surface is mouldy, to combustible liquid, sets off an explosion easily, and to poisonous and harmful liquid, then the packer of later process will be subjected to the pollution of environment.

The purpose of this utility model is exactly in order to overcome above-mentioned defective, to make the less material of surface tension can adopt the heavy caliber nozzle to carry out metering filling when can, and do not produce weeping.Both improved output, and guaranteed the quality of product again and prevented environmental pollution.

The utility model is achieved in that in plunger tpe liquid-filling machine jet pipe end, loads onto screen cloth, places in the nozzle, then nozzle is fixed on the jet pipe.

Below in conjunction with accompanying drawing the utility model is described in detail:

Fig. 1 is the utility model longitudinal sectional view.

Fig. 2 is the utility model transverse sectional view.

The utility model is made up of jet pipe (1), screen cloth (2), nozzle (3).(see figure 1), the place loads onto screen cloth (2) in jet pipe (1) lower surface, screen cloth (2) is embedded in nozzle (3) lining, distance between the end face (4) of nozzle (3) and the plane (5) of screen cloth (2) is 2～8 millimeters, then nozzle (3) is fixed on nozzle (1) and goes up (employing is threaded or bonding or welding).The internal diameter of nozzle (3) equates with the internal diameter of jet pipe (1) or is close.Form jet during liquid injecting container, the horn-like scattering of unlikely one-tenth has avoided injecting the too much foam of generation in the container.During work, jet pipe (1) and horizontal surface (ground) are in vertical state, after loading onto screen cloth (2), the end face of jet pipe (1) is separated into the very little lattice of many length of sides, just dwindled the area of liquid surface relatively, because capillary effect, the fluid molecule in each lattice is tightly held the molecule of superficial layer, form the unlikely stability of drop of liquid down of liquid level, thereby solved long-term unsolved water clock problem.

Implement special case: we improve the YG4A liquid-filling machine, jet pipe (1) is made of the stainless steel tube of inner diameter d=φ 12, screen cloth (2) is with 18～25 purpose stainless steel cloths, internal diameter＞the φ 12 of nozzle (3), screen cloth (2) is embedded in the nozzle (3), nozzle (3) adopts with jet pipe (1) and is threaded, identical at the can material, can forms under the same condition, and than adopting other forms of nozzle assembly, its production efficiency improves 1～2 times, and do not produce water clock, effect is very obvious, thereby makes the range of use of YG4A liquid-filling machine more extensive, brings bigger economic benefit to enterprise.

Claims

1, a kind of liquid-filling machine antidrip device is by jet pipe (1), and nozzle parts such as (3) are formed, and it is characterized in that: the top at the end face (4) of nozzle (3) is loaded onto a screen cloth (2) at least.

2, device according to claim 1 is characterized in that: screen cloth (2) is contained in the end of jet pipe (1), places in the nozzle (3).

3, device according to claim 1 and 2 is characterized in that: nozzle (3) is fixed on the jet pipe (1), adopts to be threaded or bonding or welding.

4, device according to claim 1 and 2 is characterized in that: the distance between the end face (4) of nozzle (3) and the plane (5) of screen cloth (2) is 2～8 millimeters, and the internal diameter of nozzle (3) equates with the internal diameter of jet pipe (1) or be close.

5, device according to claim 1 is characterized in that, screen cloth (3) material therefor is 18～25 order stainless steel cloths.
