Description

Definite quantity filling valve

Technical field

The present invention relates to a kind of liquid material material filling apparatus, in particular for liquid material definite quantity filling valve.

Background technology

Along with industrialized process is constantly pushed into, complete by hand production constantly replace by electromechanical appliance, so feed liquid filling on constantly highlight various feed liquid filling apparatus, useful microprocessor control system regulates filling and machinery to complete filling, but the main of quantitative filling or microcomputer control can be completed, for the good stability of this micro-processor controlled stability not as machinery, for this realized improving to former mechanical filling equipment, thus the operation of quantitative filling can be completed, suction when by regulating filling and the orbit period of charging complete mechanization production.

Summary of the invention

The object of the invention is that existing quantitative filling device adopts electronic machine, instrument controls the constant of the interior amount of container filling, the equipment that the quantitative filling that this employing electronic machine completes detects does not have the reliability of mechanical equipment high, for this problem, the present invention utilizes mechanical equipment to complete quantitative filling, can can also solve stability problem while guarantee quantitative filling, the orbit period of machinery can be regulated simultaneously filling to complete automation.

For achieving the above object, technical scheme of the present invention is: a kind of liquid material definite quantity filling valve comprises material storage jar, valve seat, guiding valve, groove, blanking hole, piston, piston/cylinder, material storage jar bottom is provided with the charging hole that hollow valve seat communicates, piston is equipped with in piston/cylinder inside, is provided with material hole in the end of piston/cylinder, and material hole communicates with hollow valve seat, guiding valve has groove, the axial dimension of groove is large with charging hole and the width between centers of expecting hole, and be provided with blanking hole in the lower end of groove, guiding valve is installed in valve seat.

In technique scheme, liquid material is loaded in accumulator, liquid material enters in piston/cylinder by the groove on guiding valve by the discharging sky of material storage jar bottom, there is piston to move downward again, complete the charging charging in cylinder body, container is placed in blanking hole lower end, guiding valve is up pushed away, blanking hole top in the process pushed away again on guiding valve and the end hole conducting of piston cylinder, then piston moves on the net, and the liquid material in piston cylinder is entered in container by blanking hole.

Groove is made improvements and blanking hole is positioned at same vertical plane on the periphery of guiding valve, in the process that guiding valve moves up and down, when ensureing suction: charging hole and material hole by the groove conducting on guiding valve, can expect time filling that hole can be communicated with blanking hole for such scheme.

Make improvements guiding valve for such scheme and be provided with guider screw, valve seat is provided with the guide chute coordinated with guider screw, so just limits guiding valve and can only do straight-line motion up and down.

Make improvements in space that the upper surface of guiding valve and valve seat formed for such scheme and be provided with spring, spring can make guiding valve reset.Remain at blanking hole be cut off and expect that hole and discharge opening are by arc shaped groove connected state, thus the pressure in guarantee piston cylinder can not exceed the rated pressure that piston cylinder can bear.

The lower end making improvements guiding valve for such scheme is provided with filling head, and filling head can be treated packaging container and carry out directional tagging, ensures to hold to enter along filling head.

Make improvements guiding valve lower surface discharging opening for such scheme and be provided with conical boss, the diameter container bore of conical boss is little, by the guiding of filling head, is drawing material through conical boss, can ensure that feed liquid can not spill.

To make improvements in the moving process of guiding valve blanking hole in the face of cylinder for such scheme, to decrease blanking hole and extraneous contact, ensure the health of liquid material all the time in valve seat.

accompanying drawing explanation

Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:

Fig. 1 is the suction figure of a kind of liquid material definite quantity filling valve of the present invention;

Fig. 2 is the filling figure of a kind of liquid material of the present invention definite quantity filling valve;

Mark in above-mentioned figure is: material storage jar 1, valve seat 2, spring 3, guide bolt 4, guiding valve 5, deep-slotted chip breaker 6, blanking hole 7, boss 7a, filling 8, piston 9, piston cylinder 10, end cap 11, discharge opening 12, material hole 13.

Detailed description of the invention

Embodiments of the present invention as depicted in figs. 1 and 2, comprise material storage jar 1, valve seat 2, spring 3, guide bolt 4, guiding valve 5, deep-slotted chip breaker 6, blanking hole 7, boss 7a, filling 8, piston 9, piston cylinder 10, end cap 11, this device mainly divides three parts, Part I is by material storage jar 1, second valve seat 2, spring 3, guider screw 4, guiding valve 5, deep-slotted chip breaker 6, blanking hole 7, boss 7a, filling 8, Part III piston 9, piston cylinder 10, end cap 11, Part I is mainly to storage material to be filled, Part II mainly leads to material, Part III mainly storage material and the liquid material in piston cylinder 10 is pushed in container.

As shown in Figure 1, this state is that the liquid material in material storage jar 1 enters piston cylinder, and during this state, piston 9 moves downward, and the hole of material storage jar bottom is connected with the upper end of deep-slotted chip breaker, the lower end of arc groove communicates with the hole of piston cylinder 10 upper end, and liquid material enters in piston cylinder 10 due to gravity.

When filling liquid material in piston cylinder 10, piston 9 upward movement, guiding valve 5 simultaneously also upward movement, arc groove 6 upward movement, hole and the arc groove 6 of piston cylinder 10 upper end are cut off, the upper end of blanking hole 7 communicates with the hole of piston cylinder 10 upper end as shown in Figure 2 thereupon, and continue in upward movement at piston 9, liquid material enters in container from blanking hole 7.

In ceaselessly charging process, the continuous up-and-down movement of guiding valve 5 meeting, due to arc groove 6, the position of blanking hole 7 all needs to communicate relative to the hole of piston cylinder 10 upper end at every turn, guiding valve 5 could realize batch turning, in order to ensure guiding valve 5 can only straight-line motion can not up-and-down movement, be provided with guide bolt 4 in the upper end of guiding valve 5, have vertical guide groove in the side of valve seat 2, thus realize guiding valve 5 can only up-and-down movement.

Due to when this ceaselessly filling liquid material, when there is no charge cask, spring 3 is provided with between guiding valve upper surface and valve seat, guiding valve 5 moves downward under the elastic force of spring 3, make the arc groove 6 of guiding valve 5 by the hole of piston cylinder 10 upper end and communicating bottom material storage jar, make the pressure in piston cylinder can not be excessive.

Because piston up-down has been come by cam, make the liquid material of at every turn discharging from blanking hole certain, and the cycle of container up-and-down movement and the cycle of piston consistent.

Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; without departing from the inventive concept of the premise; some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
