Description

Quantitative filling mechanism

technical field

The utility model relates to an auxiliary device for food filling, in particular to a quantitative filling mechanism.

Background technique

At present, in the sub-packaging of liquid beverages and medicines, quantitative filling machines are generally used for filling, and quantitative filling mechanisms are the main components of quantitative filling machines. The quantitative filling mechanism in the prior art mainly adopts the following structure: it includes a valve body, a movable tube, a bottle mouth seat and a return spring arranged between the valve body and the bottle mouth seat. A partition is provided, and the partition divides the inside of the movable tube into an upper cavity and a lower cavity. The upper side wall of the upper cavity is provided with an upper through hole, and the upper side wall of the lower cavity is provided with a lower through hole. The bottom of the mouth seat is an open liquid outlet. When filling, put the bottle mouth of the filling bottle facing the bottle mouth seat and lift it up. When the partition plate moves to the position of the connecting groove, the upper through hole and the lower through hole are also located in the connecting groove. The liquid in the body will flow out from the upper through hole and enter the communication groove, then flow out from the lower through hole and enter the lower cavity, and then enter the filling bottle to realize filling. After the filling is completed, remove the filling bottle, and the movable tube will move down and reset under the action of the return spring. Although the quantitative filling mechanism of this structure can successfully realize quantitative filling, its structural relationship is complicated, the manufacturing cost is high, and the efficiency of quantitative filling is not high enough, which is not conducive to popularization; It is completely open, which will cause a lot of dripping, which will not only waste products but also pollute the environment.

Attached are specific examples

Below by accompanying drawing and embodiment the utility model is described in further detail.

As shown in Figure 1: a quantitative filling mechanism, including a housing 1, a tube body 2 and a push platform 3, the inner wall of the housing 1 is provided with a blind hole 11, specifically, the blind hole 11 is an annular blind Hole 11. The blind hole 11 is movably sleeved on the upper part of the pipe body 2, and the main function of the blind hole 11 here is to allow the pipe body 2 to move up and down. The inner wall of the pipe body 2 is in sealing contact with the inner wall of the blind hole 11. In order to make the sealing contact effect better, an O-shaped sealing ring can be arranged between the inner wall of the pipe body 2 and the inner wall of the blind hole 11, so that It is more effective to prevent the liquid from flowing into the blind hole 11 from the gap between the pipe body 2 and the blind hole 11 . The housing 1 is provided with a liquid inlet 12 through which the liquid in the filling body or barrel flows into the quantitative filling mechanism. The lower end of the pipe body 2 is fixedly connected with the pushing platform 3 . In this embodiment, the lower end of the tube body 2 and the push platform 3 are fixedly connected by threads, of course, the lower end of the tube body 2 and the push platform 3 may also be designed as an integrated structure. A return spring 6 is arranged between the housing 1 and the push platform 3 . In this embodiment, the return spring 6 is set outside the casing 1, and a stepped surface is provided at the lower end of the casing 1, and the return spring 6 is located between the stepped surface and the push platform 3, so that the return spring 6 can be effectively embedded Between the housing 1 and the push table 3 a good effect is achieved. A column 4 is arranged axially at the center of the casing 1 and the pipe body 2, and the upper end of the column 4 is a fixed end 41, which is used to fix the whole mechanism under the tank or barrel. The lower end of the column 4 is provided with a sealing head 5, specifically, the sealing head 5 is located below the pipe body 2 for sealing the liquid outlet 22 at the lower end of the pipe body 2, and the sealing head 5 is made of rubber material. When the spring is in a fully released state, the sealing head 5 is in close contact with the liquid outlet 22 at the lower end of the tube body 2 . The casing 1, the tube body 2 and the sealing head 5 form a closed cavity, and the closed cavity is used for accommodating the liquid to be filled.

The working principle of the utility model is: when in use, the whole quantitative filling mechanism is fixed under the filling body or barrel body that can continuously provide liquid through the fixed end 41 on the upper end of the column 4 . Figure 1 is a structural schematic diagram of the quantitative filling mechanism in a normal state. At this time, the return spring 6 is in a fully released state, and the cavity formed by the tube body 2, the housing 1 and the sealing head is filled with liquid. The inner wall is in sealing contact with the outer wall of the pipe body 2 . When filling, the bottle mouth of the filling bottle is facing the liquid outlet 22 at the lower end of the tube body 2, and the edge of the bottle mouth is against the lower end surface of the push platform 3 and lifted up so that the push platform 3 and the tube body 2 are aligned. As the inner wall of the housing 1 moves up to the state shown in Figure 2, the sealing head 5 is separated from the liquid outlet 22 at the lower end of the tube body 2, so that the liquid in the tube body 2 is discharged from the liquid outlet 22 and flows into the bottle , to achieve the effect of filling. The amount to be filled is determined by the length of the lifting time. The longer the lifting time, the greater the filling volume, and vice versa. After the filling is completed, remove the filling bottle, and the tube body 2 and the push table 3 will move down to the original position under the action of the return spring 6 .

The above description is based on the embodiment as inspiration, and through the above description content, relevant workers can completely make various changes and modifications within the scope of not departing from the idea of the invention. The technical scope of this utility model is not limited to the content in the description, but must be determined according to the scope of the claims.
