Liquid filling machine dosing mechanism

Abstract

This utility model discloses a quantitative mechanism for a liquid filling machine, relating to the field of quantitative mechanisms for liquid filling machines. The quantitative mechanism includes a support, a filling cylinder, a filling unit, and an adjustment unit. By pushing a push rod, the mechanism causes a push seat to push the liquid in the storage cylinder downwards, discharging it from the filling tube and filling the storage cylinder with liquid. This ensures that all liquid in the storage cylinder is filled, guaranteeing accurate filling volume. By rotating a nut sleeve, the nut sleeve rotates along the storage cylinder, causing the adjustment seat to move. The adjustment seat then limits the movement of the push seat, thereby limiting the amount of liquid in the storage cylinder and facilitating quantitative control of the liquid filling volume.

Description

Technical Field

[0001] This utility model relates to the technical field of quantitative mechanisms for liquid filling machines, specifically a quantitative mechanism for a liquid filling machine. Background Technology

[0002] A liquid filling machine is a mechanical device that injects a certain amount of liquid material into a packaging container. The working principle of liquid filling machines can be divided into several types according to different filling principles, mainly including gravity filling, pressure filling, flow metering filling, and positive pressure filling.

[0003] When filling liquids, gravity filling, pressure filling, flow metering filling, and positive pressure filling are used, the amount of liquid to be filled is usually determined by measuring the filling time and flow rate. However, it is impossible to accurately control the amount of liquid entering the tank during filling. It relies on filling time and filling speed to control the amount of liquid filled within a specified time, but it cannot guarantee that the flow rate is the same, resulting in a certain error in the filling amount. Therefore, we propose a quantitative mechanism for liquid filling machines. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a quantitative mechanism for a liquid filling machine. This mechanism solves the problem that relying on filling time and filling speed to control the amount of liquid filled within a specified time cannot guarantee a uniform flow rate, leading to certain errors in the filling amount.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quantitative mechanism for a liquid filling machine, comprising a support, a filling cylinder, a filling unit, and an adjustment unit. The filling cylinder is mounted on the support and is connected to the filling unit. The adjustment unit is mounted on the filling unit.

[0006] The filling unit includes a connecting cylinder, on the inner wall of which a liquid storage cylinder is slidably connected. The outer peripheral wall of the connecting cylinder is provided with a liquid inlet pipe and a filling pipe, and the liquid inlet pipe is connected to the liquid storage cylinder and the filling cylinder.

[0007] The adjustment unit includes a push seat and an adjustment seat that are slidably connected to the inner wall of the liquid storage cylinder, with the adjustment seat located directly above the push seat.

[0008] Preferably, one end of the filling cylinder is connected to a cylinder, and a connecting pipe is provided on the filling cylinder, which is connected to the liquid filling tank.

[0009] Preferably, a connecting rod is fixedly connected to the bottom end face of the liquid storage cylinder, and a connecting seat is fixedly connected to the bottom end face of the connecting rod, the connecting seat being connected to the cylinder.

[0010] Preferably, the liquid storage cylinder has a connection hole that communicates with the liquid inlet pipe. The connection hole is located directly above the filling pipe and on one side of the push base.

[0011] Preferably, a push rod is fixedly connected to the top end face of the push seat, and the push rod is slidably connected to the inner wall of the adjustment seat.

[0012] Preferably, a nut sleeve is fixedly connected to the top end face of the adjusting seat, and the nut sleeve is threadedly connected to the inner wall of the liquid storage cylinder.

[0013] Preferably, the nut sleeve is slidably connected to the push rod, and a drive mechanism is connected to the end of the push rod outside the nut sleeve.

[0014] This utility model discloses a quantitative mechanism for a liquid filling machine, which has the following beneficial effects:

[0015] The quantitative mechanism of this liquid filling machine, by pushing the push rod to move, causes the push seat to push the liquid in the storage cylinder downwards and discharge it from the filling tube, filling the liquid in the storage cylinder completely to ensure accurate filling volume. By rotating the nut sleeve, the nut sleeve rotates along the storage cylinder, driving the adjusting seat to move. At this time, the adjusting seat limits the movement position of the push seat, thereby limiting the amount of liquid in the storage cylinder, which facilitates quantitative control of the liquid filling volume.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] This application provides a quantitative mechanism for a liquid filling machine, which solves the problem that relying on filling time and speed to control the amount of liquid filled within a specified time cannot guarantee a consistent flow rate, leading to errors in the filling amount. The mechanism achieves this by moving the push rod 402, causing the push seat 401 to push the liquid in the storage cylinder 302 downwards, discharging it from the filling tube 501, thus filling the liquid in the storage cylinder 302 completely and ensuring accurate filling. By rotating the nut sleeve 404, it rotates along the storage cylinder 302, causing the adjusting seat 403 to move. The adjusting seat 403 then limits the movement of the push seat 401, thereby limiting the amount of liquid in the storage cylinder 302 and facilitating quantitative control of the liquid filling amount.

[0023] It should be noted that a locking nut (not shown in the drawing) is installed on the nut sleeve 404, and the locking nut can limit the position of the nut sleeve 404 at will;

[0024] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0025] This utility model discloses a quantitative mechanism for a liquid filling machine, according to the attached... Figures 1-3 As shown, the system includes a support 1, a filling cylinder 2, a filling unit 3, and an adjusting unit 4. The filling cylinder 2 is mounted on the support 1 and is connected to the filling unit 3. The adjusting unit 4 is mounted on the filling unit 3.

[0026] The filling unit 3 includes a connecting cylinder 301, on the inner wall of which a liquid storage cylinder 302 is slidably connected. The outer peripheral wall of the connecting cylinder 301 is provided with a liquid inlet pipe 5 and a filling pipe 501. The liquid inlet pipe 5 is connected to the liquid storage cylinder 302 and the filling cylinder 2. By pushing the push rod 402 to move, the push seat 401 pushes the liquid in the liquid storage cylinder 302 downward to discharge it from the filling pipe 501, filling the liquid in the liquid storage cylinder 302. The liquid in the liquid storage cylinder 302 is completely filled, ensuring the filling amount is accurate.

[0027] The adjustment unit 4 includes a push seat 401 and an adjustment seat 403 slidably connected to the inner wall of the liquid storage cylinder 302. The adjustment seat 403 is located directly above the push seat 401. By rotating the nut sleeve 404, the nut sleeve 404 rotates along the liquid storage cylinder 302. Under the action of the nut sleeve 404, the adjustment seat 403 moves. At this time, the adjustment seat 403 limits the movement position of the push seat 401, thereby limiting the amount of liquid in the liquid storage cylinder 302, which facilitates quantitative control of the liquid filling amount.

[0028] One end of the filling cylinder 2 is connected to a cylinder. The filling cylinder 2 is equipped with a connecting pipe that is connected to a liquid filling tank. The liquid in the liquid filling tank is transported to the filling cylinder 2. The cylinder is started to push the liquid in the filling cylinder 2 to the liquid storage cylinder 302.

[0029] At this time, the liquid in the filling cylinder 2 enters the storage cylinder 302 through the liquid inlet pipe 5, causing the liquid to push the pusher seat 401 to slide on the inner wall of the storage cylinder 302.

[0030] A connecting rod 304 is fixedly connected to the bottom end face of the liquid storage cylinder 302, and a connecting seat 303 is fixedly connected to the bottom end face of the connecting rod 304. The connecting seat 303 is connected to a cylinder, and the cylinder drives the connecting seat 303 and the connecting rod 304 to move. At this time, the connecting rod 304 drives the liquid storage cylinder 302 to slide along the inner wall of the connecting cylinder 301. At this time, the connecting hole on the liquid storage cylinder 302 is separated from the liquid inlet pipe 5 and connected to the filling pipe 501. At this time, by pushing the push rod 402 to move, the push seat 401 pushes the liquid in the liquid storage cylinder 302 downward to discharge it from the filling pipe 501, filling the liquid in the liquid storage cylinder 302. The liquid in the liquid storage cylinder 302 is completely filled to ensure the filling amount.

[0031] The liquid storage cylinder 302 has a connection hole that is connected to the liquid inlet pipe 5. The connection hole is located directly above the filling pipe 501 and on one side of the push seat 401. When the connecting rod 304 drives the liquid storage cylinder 302 to slide along the inner wall of the connecting cylinder 301, the connection hole on the liquid storage cylinder 302 separates from the liquid inlet pipe 5 and connects to the filling pipe 501, thus facilitating filling.

[0032] A push rod 402 is fixedly connected to the top end face of the push seat 401, and the push rod 402 is slidably connected to the inner wall of the adjustment seat 403.

[0033] A nut sleeve 404 is fixedly connected to the top end face of the adjusting seat 403. The nut sleeve 404 is threadedly connected to the inner wall of the liquid storage cylinder 302. By rotating the nut sleeve 404, the nut sleeve 404 rotates along the liquid storage cylinder 302. Under the action of the nut sleeve 404, the adjusting seat 403 moves. At this time, the adjusting seat 403 limits the movement position of the pushing seat 401, thereby limiting the liquid volume in the liquid storage cylinder 302, which facilitates quantitative control of the liquid filling volume.

[0034] The nut sleeve 404 is slidably connected to the push rod 402. The end of the push rod 402 located outside the nut sleeve 404 is connected to a drive mechanism. The drive mechanism drives the push rod 402 to move, so that the push rod 402 drives the push seat 401 to slide on the inner wall of the liquid storage cylinder 302, and the liquid in the liquid storage cylinder 302 is discharged to the outside through the filling pipe 501 for filling.

[0035] After filling is completed, the connecting seat 303 and the connecting rod 304 move in opposite directions, which pushes the liquid storage cylinder 302 to move upward, so that the connecting hole on the liquid storage cylinder 302 is connected to the liquid inlet pipe 5 and separated from the filling pipe 501. At this time, the liquid in the filling cylinder 2 enters the liquid storage cylinder 302 through the liquid inlet pipe 5 for reciprocating filling.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
