Description

Technical Field

[0001] This utility model relates to the field of volume control devices, and in particular to a precise liquid volume control device. Background Technology

[0002] A filling machine is a machine used to automatically or semi-automatically fill liquids, powders, granules or other types of materials into containers, which can be bottles, cans, bags, barrels or other types of packaging containers.

[0003] When filling bottled liquids, a filling machine is usually used for precise filling. This involves installing a solenoid valve on the drain pipe of the filling machine. The solenoid valve works in conjunction with the liquid delivery mechanism to ensure that the drain pipe accurately dispenses the liquid in a measured quantity.

[0004] The drain pipe is directly fixed to the mounting frame using bolts and fasteners. The drive mechanism on the filling machine can then move the mounting frame and the drain pipe up and down, allowing the drain pipe to descend and connect with the liquid bottle. However, when maintenance is required on the drain pipe or its external solenoid valve, the bolts and fasteners need to be removed, allowing the drain pipe to be disassembled for maintenance. But when removing the bolts, the frame on the filling machine will obstruct the process, reducing the ease of installing or removing the drain pipe. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figure 1-3 The liquid precision volume control device shown includes a filling machine 1, a mounting frame 2 mounted on the filling machine 1, and a cylinder mounted on the support of the filling machine 1 to guide and drive the mounting frame 2, thereby driving the mounting frame 2 to move up and down. When the mounting frame 2 descends, it can drive the drain pipe 3 to connect with the liquid carrier bottle. The bottom of the mounting frame 2 is provided with the drain pipe 3, and a solenoid valve 4 is installed on the drain pipe 3. An installation assembly 5 is provided between the drain pipe 3 and the mounting frame 2. The top of the drain pipe 3 is connected to a connecting pipe 6. The drain pipe 3 can be connected to the liquid delivery pump of the filling machine 1 through the connecting pipe 6, and under the control of the solenoid valve 4, the liquid can be precisely quantitatively filled.

[0024] In particular, the mounting assembly 5 includes a connecting collar 51, a positioning plate 52, and a limiting spring 53. The connecting collar 51 is slidably sleeved on the top of the outer wall of the drain pipe 3, and the outer wall of the connecting collar 51 is slidably engaged with the mounting bracket 2. The positioning plate 52 is installed on the outer wall of the drain pipe 3, and the limiting spring 53 is located at the bottom of the positioning plate 52. Under the action of the limiting spring 53, the positioning plate 52 is slidably engaged with the inside of the mounting bracket 2. The limiting spring 53 can provide an elastic support force to the positioning plate 52, thereby ensuring that the positioning plate 52 is stably engaged with the inside of the mounting bracket 2, thus ensuring the stability of the drain pipe 3 installed on the mounting bracket 2. A connecting hole 54 is opened at the top of the mounting bracket 2, and the outer wall of the connecting collar 51 is slidably sleeved with the inner cavity of the connecting hole 54. A limiting disc 55 is fixedly connected to the top of the mounting frame 2. The inner wall of the connecting hole 54 is provided with a slot 56, and one side of the multiple drain pipes 3 installed on the mounting frame 2 corresponds to one side of a slot 56. The inner cavity of the slot 56 matches the limiting disc 55, thereby pulling the drain pipe 3 downward, causing the drain pipe 3 to drive the positioning plate 52 to slide downward, releasing the positioning plate 52 from the mounting frame 2. The drain pipe 3 can then slide horizontally relative to the mounting frame 2, causing the drain pipe 3 to drive the connecting collar 51 and the limiting disc 55 to slide on the mounting frame 2 until the limiting disc 55 corresponds to the slot 56. Thus, the limiting disc 55 can be directly slid from the slot 56 to the bottom of the mounting frame 2, thereby completing the disassembly of the drain pipe 3.

[0025] Specifically, a connecting rod 57 is fixedly connected to the bottom of the connecting collar 51. The outer wall of the connecting rod 57 is slidably sleeved with the positioning plate 52. A limit block 58 is fixedly connected to the bottom of the connecting rod 57. The outer wall of the connecting rod 57 is slidably sleeved with the limit spring 53. The limit spring 53 is located between the limit block 58 and the positioning plate 52. The connecting rod 57 can guide the connection between the positioning plate 52 and the connecting collar 51. Under the limitation of the connecting rod 57 and the limit block 58, the elastic force of the limit spring 53 at the top of the limit spring 53 to the positioning plate 52 is sufficient to support the weight of the positioning plate 52 and the drain pipe 3, and can allow the positioning plate 52 to be snapped onto the bottom of the mounting bracket 2.

[0026] Furthermore, positioning rods 510 are symmetrically fixedly connected to the top of the positioning plate 52, and positioning blocks 59 are fixedly connected to the top of the inner wall of the mounting frame 2. Positioning slots are provided at the bottom of the positioning blocks 59. The outer wall of the positioning rods 510 slides and engages with the inner cavity of the positioning slots. The positioning rods 510 on the top of the positioning plate 52 engage with the positioning blocks 59 inside the mounting frame 2, thus limiting the engagement of the positioning plate 52 and preventing it from sliding horizontally inside the mounting frame 2. This, in conjunction with the connecting collar 51 and the limiting disc 55, limits the engagement of the drain pipe 3, ensuring... To ensure the stability of the drain pipe 3 installation, pulling down the drain pipe 3 will cause the positioning rod 510 to separate from the positioning block 59 via the positioning plate 52, releasing the locking state of the positioning plate 52. The positioning plate 52 is fixedly connected to the mounting sleeve 511, which is slidably sleeved on the outer wall of the drain pipe 3. The mounting sleeve 511 is provided with mounting screws 512 on its outside. The mounting sleeve 511 is installed on the outer wall of the drain pipe 3 by the mounting screws 512. By removing the mounting screws 512, the positioning plate 52 can be directly slidably separated from the drain pipe 3.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
