In order to solve the technical problems, the utility model provides the following technical scheme: the conveying pipe is fixed at the bottom of the mounting table, a sleeve is connected to the bottom of the conveying pipe in a sliding mode, a spring is arranged between the upper end face of the sleeve and the bottom face of the mounting table, and the spring is sleeved on the periphery of the conveying pipe;

in an initial state, the sleeve is hung at the end part of the conveying pipe, and the self stress of the spring is in a normal state or a stretching state;

the conveying pipe is internally provided with a turning plate valve block which is rotationally connected in the conveying pipe through a rotating shaft, the rotating shaft extends out of the conveying pipe and is connected with a gear at the end part, and the inner wall of the sleeve is provided with a rack.

Preferably, the sleeve is in a bell mouth shape, and has a structure with a large outer part and a small inner part.

Preferably, the inner wall of the sleeve is provided with a rubber cushion layer.

Preferably, the delivery pipes are arranged in groups in a rectangular array on the mounting table.

Preferably, the connecting rail is installed on the side part of the mounting table, the linear driving device is additionally arranged, and the output end of the linear driving device is fixedly connected with the connecting rail, so that the mounting table is controlled to move up and down.

Preferably, the input end of the conveying pipe is provided with a pipe connecting flange.

Compared with the prior art, the utility model has the beneficial effects that:

the filling device is reasonable in structure and convenient to use, is applied to laboratories or other small-scale filling environments, and can be used for directly manually inserting the bottle into the sleeve to realize liquid filling; no additional control valve operation is required.

Detailed Description

For convenience in use, the embodiment of the utility model provides a liquid filling device. The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the examples of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The embodiment provides a liquid filling device, which firstly refers to fig. 1 and comprises a conveying pipe 5 and an installation platform 1, wherein the conveying pipe 5 is fixed at the bottom of the installation platform 1, the bottom of the conveying pipe 5 is connected with a sleeve 6 in a sliding manner, a spring 4 is arranged between the upper end surface of the sleeve 6 and the bottom surface of the installation platform, and the spring 4 is sleeved on the periphery of the conveying pipe;

in the initial state, the sleeve 6 is hung at the end part of the conveying pipe, and the self stress of the spring 4 is in a normal state or a stretching state;

a flap valve plate 51 is arranged in the conveying pipe 5, the flap valve plate 51 is rotationally connected in the conveying pipe through a rotating shaft 52, the rotating shaft 52 extends out of the conveying pipe, a gear 53 is connected at the end part, and a rack is arranged on the inner wall of the sleeve 6.

In order to facilitate the insertion of the bottle mouth and keep relative sealing, the sleeve 6 is designed into a structure with a bell mouth shape and a large outer part and a small inner part, and a layer of rubber cushion layer is arranged on the inner wall of the air-holding sleeve.

When in use, the top of the conveying pipe 5 is connected with an infusion pipeline by the connecting pipe flange 3. When the bottle needs to be filled, one end of the bottle mouth is directly inserted into the sleeve 6, after the bottle mouth is abutted against the inner wall of the sleeve 6, the sleeve 6 is pushed to slide upwards relative to the conveying pipe 5, and the flap valve plate 51 is opened under the action of the rack and the gear 53 to fill. When the bottle is about to finish moving downwards, the sleeve 6 continues to abut against the bottle mouth downwards under the action of the spring until the flap valve plate 51 is closed, and at the moment, the bottle mouth is directly moved out of the sleeve 6 under the condition of returning to the initial state.

It should be noted that, as shown in fig. 3, the conveying pipes 5 are arranged in a plurality of groups on the mounting table 11 in a rectangular array to form a multi-head filling device. The connecting rail 2 is arranged on the side part of the mounting table 1, a linear driving device (such as an air cylinder or a screw rod) is additionally arranged, and the output end of the linear driving device is fixedly connected with the connecting rail 2, so that the mounting table is controlled to move up and down. In use, the bottle can be placed at the bottom of the sleeve, and the whole body is driven by the driving device to move downwards, so that automatic filling is realized.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
