Detailed Description

In order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the present utility model more clear and easy to understand, the present utility model is further described below with reference to the accompanying drawings and the detailed description:

as shown in fig. 1-2, the present embodiment provides a metering device for feeding liquid materials, and in terms of structure, the metering device includes a plurality of filling tanks 1 for containing liquid, wherein the filling tanks 1 are provided with a plurality of non-identical specifications, and the filling tanks 1 can be further connected with packaging bottles of corresponding specifications according to requirements. Meanwhile, the metering device further comprises a vertically installed cache cylinder 2, a three-way electromagnetic liquid inlet valve 4 is installed at the bottom end of the cache cylinder 2, a plurality of overflow holes 3 with different heights are formed in the cylinder wall of the cache cylinder 2, each overflow hole 3 is connected with a filling tank 1, and the two overflow holes are connected through corresponding pipelines, so that the two overflow holes are directly connected, and when the overflow holes 3 are not overflowed any more, namely, liquid does not flow out towards one overflow hole 3 any more, the liquid in the filling tank 1 reaches the rated volume, and the metering device can be designed to be filled with the filling tank 1. In addition, all the bottom ends of all the filling cans 1 are provided with electromagnetic valves 5 for discharging liquid, namely, the outlet end of each electromagnetic valve 5 is connected with a packaging bottle with a corresponding specification, when the liquid level in the buffer storage barrel 2 exceeds the highest overflow hole 3, the three-way electromagnetic liquid inlet valve 4 is turned to the other outlet for discharging liquid, and all the electromagnetic valves 5 are opened after the liquid is discharged, because all the filling cans 1 reach the rated liquid volume at the moment. When the liquid material filling device is used, liquid materials are firstly conveyed into the buffer storage cylinder 2, the liquid level in the buffer storage cylinder 2 is gradually increased, when the liquid level reaches the overflow hole 3 at the lowest position, liquid starts to be filled into the first filling cylinder 1 through the overflow hole 3, when the filling cylinder 1 is filled or reaches the rated volume, the liquid level in the buffer storage cylinder 2 is continuously increased, then the second overflow hole 3 from bottom to top starts to overflow, the second filling cylinder 1 is filled, all the filling cylinders 1 are gradually filled with the liquid materials, and finally the electromagnetic valve 5 is opened, so that the liquid materials can be further quantitatively conveyed to a required container, such as a packaging bottle.

When specifically manufactured, the electromagnetic valve 5 is connected with a controller (not shown in the figure), as shown in fig. 1, a sliding block 8 is suspended on the inner top wall of the buffer cylinder 2, and a distance sensor (not shown in the figure) which is also connected with the controller is fixed, the distance sensor detects the normal distance between the distance sensor and the sliding block 8, namely, the distance is almost unchanged in the non-working state, when filling is started, the liquid level in the buffer cylinder 2 rises, finally, the sliding block 8 moves upwards when reaching the overflow hole 3 at the highest position and not passing through the overflow hole 3, so that the normal distance detected by the sensor is reduced, the controller is triggered to drive the three-way electromagnetic liquid inlet valve 4 to turn a runner to drain liquid, and then all the electromagnetic valves 5 are driven to open to realize the discharging of each filling cylinder 1.

As shown in fig. 1, the sliding block 8 of the present embodiment may be suspended by a spring 7, for example, a light spring 7, and a limit post 6 fixedly connected to the buffer cylinder 2 is provided at the top end of the spring 7, so as to prevent the spring 7 from being excessively compressed in an unexpected situation, and enable the sliding block to be suspended relatively stably. The length direction of the filling tank 1 in this embodiment is arranged along the radial direction of the buffer tank 2, so that the opposite filling tanks 1 are convenient to set. During specific installation, the filling tank 1 is installed on the ground through a plurality of brackets 9 to play a supporting role, and one side of the filling tank 1 is installed in a guide groove on the outer wall of the buffer tank 2 in a socket fit manner, so that the filling tank 1 and the corresponding overflow hole 3 are well aligned for installation, as shown in fig. 3, the guide groove can be specifically formed by a pair of limiting blocks 13 which are oppositely arranged.

As a specific implementation detail, the overflow holes 3 are arranged at intervals along a spiral path on the wall of the buffer vessel 2, so that a large enough interval is provided between the surrounding filling vessels 1, and the overflow holes 3 have a large height difference as much as possible.

As a further embodiment, it is recommended to provide a plunger 10 which is mounted in the buffer vessel 2 in a vertically sliding fit, as shown in fig. 4, wherein the plunger 10 is cylindrical and can slide vertically but cannot rotate, and the plunger 10 has a blind hole 12 with a closed top end and an open bottom end in the axial direction inside, and the external liquid is poured into the blind hole 12 after entering the buffer vessel 2. Meanwhile, a plurality of drainage holes 11 are formed in the cylindrical surface of the plunger 10, the drainage holes 11 are of a waist-shaped hole structure, and all the drainage holes 11 are communicated with the blind holes 12, so that liquid is conveyed; the drainage holes 11 are arranged in a one-to-one correspondence with the overflow holes 3, i.e. in a certain vertical direction, only one drainage hole 11 and one overflow hole 3 are communicated when the drainage hole 11 vertically moves to the height position of the overflow hole 3, so that liquid can be conveyed, and the only passage for conveying the liquid to the outside of the buffer drum 2 in the period of time is realized. When all the plunger 10 is manufactured, when the plunger 10 is required to move vertically, each drainage hole 11 is provided with a unique overflow hole 3 which is aligned and communicated with the plunger, and at the same height position, only one drainage hole 11 is communicated with the corresponding overflow hole 3. The design and manufacture are carried out in such a way that when the liquid level in the buffer cylinder 2 exceeds the highest overflow hole 3, the liquid in the buffer cylinder 2 is discharged by rotating the three-way electromagnetic liquid inlet valve 4 to the other outlet, because even if all the electromagnetic valves 5 are directly opened at this time, the liquid in the buffer cylinder 2 cannot flow into the filling tank 1 filled or injected with the rated volume, the structure is simpler, and the filling quantity and the filling speed of the corresponding filling tank 1 can be further adjusted by changing the design length of each waist hole.

Finally, it is noted that the above embodiments are only for illustrating the technical solution of the present utility model and not for limiting the same, and although the present utility model has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the technical solution of the present utility model, which is intended to be covered by the scope of the claims of the present utility model.
