Description

Quantified filling mechanism

Technical field

The utility model relates to a kind of auxiliary device for food filling, is specifically a kind of Quantified filling mechanism.

Background technology

At present, in liquid beverage, drugs packaging, generally adopt dosing filling machine to carry out filling, Quantified filling mechanism is the chief component of dosing filling machine.The Quantified filling mechanism of prior art is mainly taked following structure: comprise valve body, adjustable pipe, bottleneck seat and be arranged on valve body and bottleneck seat between retracing spring, in the inwall on valve body top, be provided with UNICOM's groove, in adjustable pipe, be provided with dividing plate, dividing plate is divided into upper cavity and lower chamber by adjustable pipe inside, on the lower sides of upper cavity, be provided with through hole, in the upper portion side wall of lower chamber, be provided with lower through-hole, the bottom of bottleneck seat is a unlimited liquid outlet.When filling, by the bottleneck of filling bottle just to bottleneck seat, and up hold up, when moving to connectivity slot position on dividing plate, now go up through hole and lower through-hole and be also arranged in UNICOM's groove, liquid in upper cavity enters UNICOM's groove after can flowing out from upper through hole, and then from lower through-hole flow out after enter lower chamber, enter subsequently in filling bottle, realize filling.After filling, remove filling bottle, adjustable pipe can move down reset under the effect of retracing spring.Although the Quantified filling mechanism of this structure can be realized quantitative filling smoothly, its structural relation complexity, manufacturing cost is high, and the efficiency of quantitative filling is also not high enough, is unfavorable for promoting; Moreover because the liquid outlet of bottleneck seat bottom opens wide completely, this can cause a large amount of weepings, not only waste product but also pollute the environment.

Summary of the invention

The purpose of this utility model is to provide a kind of simple in structure, low cost of manufacture, and can effectively avoid residual liquid weeping, the Quantified filling mechanism that filling accuracy is high.

To achieve these goals, the technical solution of the utility model is as follows: oneplant Quantified filling mechanism, it is characterized in that: comprise housing, body and push away platform; The inwall of described housing is provided with blind hole, and blind hole is movably set in the top of body; The inwall of described body seals and contacts mutually with the inwall of blind hole; Described housing is provided with inlet; The lower end of described body with push away platform and be fixedly connected with; Described housing and push away a retracing spring is set between platform; The center of described housing and body axially arranges a column, and the upper end of column is fixed end, and the lower end of column is provided with sealing head.

As improvement, described retracing spring is sleeved on outside, and the lower end of housing is provided with a cascaded surface, and retracing spring is at cascaded surface and push away between platform.This reasonable in design, can be embedded in retracing spring actv. housing and push away between platform, reaches good effect.

As preferably, the lower end of described body is fixedly connected with by screw thread with pushing away between platform.This structure design is simple, easy for installation, is convenient to batch manufacturing.

As preferably, when spring is during in complete release position, sealing head and body lower end liquid outlet close contact.

Adopt after technique scheme, the utility model compared with prior art, has the following advantages: the utility model Quantified filling mechanism is simple in structure, low cost of manufacture; When filling stopping, under the effect of retracing spring, sealing head can with body lower end liquid outlet close contact, seal up liquid outlet, thereby effectively avoid residual liquid weeping, filling accuracy is higher.

Shown in figure: 1, housing 11, blind hole 12, inlet 2, body 22, liquid outlet 3, push away platform 4, column 41, fixed end 5, sealing head 6, retracing spring.

attached specific embodiment

Below by drawings and Examples, the utility model is further elaborated.

As shown in Figure 1: a kind of Quantified filling mechanism, comprise housing 1, body 2 and push away platform 3, the inwall of described housing 1 is provided with blind hole 11, and specifically, described blind hole 11 is annular blind hole 11.Described blind hole 11 is movably set in the top of body 2, and blind hole 11 the Main Function is here up and down for body 2.The inwall of described body 2 seals and contacts mutually with the inwall of blind hole 11, in order to make sealing contact better effects if, can between the inwall of body 2 and the inwall of blind hole 11,0 RunddichtringO be set, so just actv. prevents that liquid from flowing into blind hole 11 from the gap between body 2 and blind hole 11 more.Described housing 1 is provided with inlet 12, and the liquid of filling with in body or staving flows in this Quantified filling mechanism by this inlet 12.The lower end of described body 2 with push away platform 3 and be fixedly connected with.In the present embodiment, the lower end of described body 2 is fixedly connected with by screw thread with pushing away between platform 3, can certainly and push away platform 3 by the lower end of body 2 and be designed to integrated structure.Described housing 1 and push away a retracing spring 6 is set between platform 3.In the present embodiment, described retracing spring 6 is sleeved on housing 1 outside, and the lower end of housing 1 is provided with a cascaded surface, and retracing spring 6 is at cascaded surface and push away between platform 3, so just retracing spring 6 actvies can be embedded in to housing 1 and push away between platform 3, reaches good effect.Described housing 1 axially arranges a column 4 with the center of body 2, and the upper end of column 4 is fixed end 41, and this fixed end 41 is for being fixed on whole mechanism under tank body or staving.The lower end of column 4 is provided with sealing head 5, and specifically, sealing 5 is positioned at body 2 belows, and for sealed tube body 2 lower end liquid outlets 22, and sealing head 5 consists of elastomeric material.When spring is during in complete release position, sealing head 5 and body 2 lower end liquid outlet 22 close contacts.Housing 1, body 2 and sealing head 5 form the cavity of a sealing, and the cavity of sealing is for the liquid of accommodating filling to be installed.

Principle of work of the present utility model is: during use, whole Quantified filling mechanism is fixed under the filling body or staving that liquid can be provided continually by the fixed end 41 of column 4 upper ends.If Fig. 1 is the structural representation of Quantified filling mechanism under conventional state, now retracing spring 6, in complete release position, is filled liquid in the cavity that body 2, housing 1 and sealing head form, and the inwall of housing 1 seals and contacts mutually with the outer wall of body 2.When filling, by the just liquid outlet 22 to body 2 lower ends of the bottleneck of filling bottle, the edge of bottleneck props up and pushes away the lower surface of platform 3 and up hold up, make to push away platform 3 and along the inwall of housing 1, be moved upward to state as shown in Figure 2 with body 2, now sealing head 5 departs from body 2 lower end liquid outlets 22, liquid in body 2 is discharged from liquid outlet 22, flow in bottle, reach filling effect.Need filling amount by the length of the time of lifting, to be determined, the time of lifting is longer, and filling amount is larger, otherwise, contrary.After filling, remove filling bottle, body 2 and push away platform 3 can be moved downward to original position under the effect of retracing spring 6.

The above is enlightenment according to embodiment, and by above-mentioned description, relevant staff can, not departing from the scope of this invention thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on specification sheets, must determine according to claim scope.
