Although liquid quantitative control systems have been widely used in various fields, in some specific application scenarios, such as chemical production or medical fields with high precision requirements, the existing control system may still not meet the needs, and the flexibility and practicality are low.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a liquid material quantitative control device, comprising a control pipeline, wherein the top and the inside of the control pipeline are provided with an adjustment control mechanism;

[0006] The regulating control mechanism comprises a sealing plate fixedly mounted on the top of the control pipe, a mounting box fixedly mounted inside the sealing plate, a control motor fixedly mounted on the top of the mounting box, a threaded rod rotatably connected to the mounting box fixedly mounted on the output shaft of the control motor, a threaded block threadedly connected to the outer side of the threaded rod, and a fixing plate fixedly mounted on both the left and right sides of the threaded block;

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 A liquid material quantitative control device in this embodiment includes a control pipeline 1, and an adjustment control mechanism is arranged on the top and inside of the control pipeline 1.

[0022] In this embodiment, the regulating and controlling mechanism includes a sealing plate 2 fixedly installed on the top of the control pipe 1, an installation box 3 is fixedly installed inside the sealing plate 2, an installation groove is opened inside the sealing plate 2, and the installation box 3 is fixedly connected to the sealing plate 2 through the installation groove, which helps to install and fix the installation box 3, and a control motor 4 is fixedly installed on the top of the installation box 3.

[0023] Among them, the output shaft of the control motor 4 is fixedly installed with a threaded rod 5 rotatably connected to the installation box 3, the outer side of the threaded rod 5 is threadedly connected with a threaded block 6, and a threaded groove is opened inside the threaded block 6. The threaded block 6 is threadedly connected to the threaded rod 5 through the threaded groove, which facilitates the movement of the threaded block 6 on the outer side of the threaded rod 5. Fixed plates 7 are fixedly installed on the left and right sides of the threaded block 6.

[0024] In this embodiment, a limit block 8 is fixedly installed on one side of the fixed plate 7 away from the threaded block 6 and is slidably connected to the installation box 3. Limit grooves are provided on the inner walls of the left and right sides of the installation box 3. The limit block 8 is slidably connected to the installation box 3 through the limit grooves, which helps to limit the limit block 8. A movable rod 9 movably connected to the installation box 3 is fixedly installed on the bottom of the fixed plate 7. A through groove is provided at the bottom of the installation box 3. The movable rod 9 is movably connected to the installation box 3 through the through groove, which helps to move the movable rod 9 inside the installation box 3.

[0025] Among them, a sealing block 10 that fits with the control pipe 1 is fixedly installed on one side of the movable rod 9, and the adjustment and control mechanism also includes a feed pipe 11 fixedly installed on the left and right sides of the control pipe 1, and the discharge pipe 12 corresponds to the position of the sealing block 10. The sealing block 10 seals the discharge pipe 12, which helps to adjust and control the feed pipe 11. The discharge pipe 12 is fixedly installed at the bottom of the control pipe 1, and a control valve 13 is arranged on the outside of the discharge pipe 12. A control panel 14 is fixedly installed on the front of the control pipe 1.

[0026] It should be noted that the liquid material quantitative control device, through the setting of the adjustment control mechanism, uses the control motor 4 to drive the threaded rod 5 to rotate, and the threaded block 6 on the outside of the threaded block 6 is limited by the fixed plate 7 and the limit block 8, and the threaded block 6 begins to move stably. The movement of the threaded block 6 drives the fixed plate 7 to move downward, and the sealing block 10 moves downward to block and seal the feed pipe 11, thereby reducing the feeding amount of the feed pipe 11, or it can drive the fixed plate 7 to move upward to drive the movable rod 9 and the sealing block 10 to move upward, thereby reducing the sealing of the feed pipe 11 by the sealing block 10, facilitating the increase of the discharge amount of the feed pipe 11, and helping to quickly adjust and control the discharge amount of the liquid material.

[0027] The working principle of the above embodiment is:

[0028] The liquid material quantitative control device can firstly convey the material through the feed pipe 11 when in use, the material enters the interior of the control pipe 1 through the feed pipe 11, and then flows into the interior of the discharge pipe 12 through the control pipe 1, and is recovered. During use, when it is necessary to adjust and control the flow of the liquid material, the control motor 4 can be started using the control panel 14, and the control motor 4 drives the threaded rod 5 to rotate rapidly. The threaded block 6 on the outer side of the threaded rod 5 is limited by the fixed plate 7 and the limit block 8, and the threaded block 6 starts to move stably, and the movement of the threaded block 6 drives the fixed plate 7 downward. The fixed plate 7 moves, and the movable rod 9 and the sealing block 10 move. The sealing block 10 moves downward to block and seal the feed pipe 11, thereby reducing the feeding amount of the feed pipe 11. Similarly, the control motor 4 can be started to drive the threaded rod 5 to rotate in the opposite direction, and the threaded block 6 and the fixed plate 7 move upward. The fixed plate 7 moves upward and drives the movable rod 9 and the sealing block 10 to move upward, thereby reducing the sealing of the feed pipe 11 by the sealing block 10, facilitating the increase of the discharge amount of the feed pipe 11, and facilitating the rapid adjustment and control of the discharge amount of the liquid material, thereby increasing the flexibility and practicality of the device.
