Description

Technical Field

[0001] This utility model relates to the technical field of anti-drip devices, and in particular to an anti-drip device for a servo sprayer. Background Technology

[0002] A servo sprayer is a device that uses a servo control system to precisely control the spraying operation. It is commonly used in agriculture, horticulture, industrial spraying, medical disinfection, and other fields to accurately apply release agents, pesticides, fertilizers, coatings, or disinfectants.

[0003] Patent CN220093007U discloses a servo sprayer, comprising a base, a horizontal linear drive device mounted on the base, a horizontal movable plate driven by the horizontal linear drive device, a spraying mechanism and a controller mounted on the horizontal movable plate. The spraying mechanism includes a servo motor mounted on the horizontal movable plate, a rotating arm driven by the servo motor, a support cylinder hinged to the horizontal movable plate, a support arm hinged to one side of the servo motor, a telescopic cylinder, two connecting plates arranged side-by-side on the sidewalls of the telescopic cylinder, a pad plate driven by the telescopic cylinder, and several spray heads distributed at the bottom of the pad plate. One end of the rotating arm and the support arm are both hinged between the two connecting plates. Although the above patent uses a telescopic cylinder to drive the spray heads to move back and forth, adjusting the distance between the spray heads and the mold to adapt to the spraying needs of molds of different depths, improving the applicability of the equipment and reducing costs, it still has certain shortcomings. After the spraying operation is completed, residual release agent in the pipeline system will drip from the spray heads, not only wasting raw materials but also contaminating the mold and product, seriously affecting production quality and the safety of the working environment.

[0004] Therefore, a drip-proof device for servo sprayers is needed. Utility Model Content

[0005] In order to overcome the shortcomings of existing patents, where residual release agent in the pipeline system drips from the spray head after the spraying operation, which not only wastes raw materials but also contaminates molds and products, seriously affecting production quality and working environment safety, this utility model provides an anti-drip device for servo sprayers.

[0006] The technical solution is as follows: A drip-proof device for a servo sprayer includes a base plate, a support column, a support plate, a moving structure, a storage tank, a delivery pipe, a pipeline pump, a nozzle, a spray pipe, an internal thread, and a nozzle.

[0012] Compared with the prior art, this utility model provides an anti-drip device for a servo sprayer, which has the following beneficial effects: 1. When the pipeline pump stops working, the pressure inside the nozzle drops rapidly. At this time, the sliding rod moves up automatically under the action of the tension spring, which drives the sealing plug to block the liquid outlet at the bottom of the nozzle, blocking the release agent from flowing down, thereby effectively preventing residual release agent from dripping from the nozzle.

[0013] 2. By working in concert with three sets of drive mechanisms, the spatial movement flexibility of the nozzle is improved, enabling multi-directional and automated spraying coverage of the release agent. Attached Figure Description

[0021] Example 1: An anti-drip device for a servo sprayer, please refer to... Figures 1-5The system includes a base plate 1, a support column 2, a support plate 3, a moving structure, a storage tank 16, a delivery pipe 17, a pipeline pump 18, a nozzle 20, a spray pipe 2001, an internal thread 24, and a nozzle 25. The support column 2 is fixedly connected to the front of the base plate 1, and the support plate 3 is fixedly connected to the top of the support column 2. The storage tank 16 is mounted on the base plate 1. The right side of the storage tank 16 is connected to and connected to the delivery pipe 17, which is a flexible hose. The pipeline pump 18 is installed near the storage tank 16 on the delivery pipe 17. The other end of the delivery pipe 17 is connected to and connected to the nozzle 20. The bottom of the nozzle 20 is connected to and connected to the spray pipe 2001. The lower part of the spray pipe 2001 has an internal thread 24, and a nozzle is threaded onto the lower part of the spray pipe 2001. 25. A movable structure is provided on the support plate 3. The movable structure is used to drive the nozzle 20 to move in multiple directions. The movable structure includes a guide rail 4, a sliding seat 5, an electric push rod 6, a support base 7, a screw 8, a guide rod 9, a servo motor 10, a pulley assembly 11, a mounting base 12, a mounting plate 13, an electric slide rail 14, and an electric slider 15. The top of the support plate 3 is fixedly connected to the guide rail 4, and the sliding seat 5 is slidably arranged on the guide rail 4. Two electric push rods 6 are installed on the rear side of the support plate 3. The piston rods of the electric push rods 6 are connected to the sliding seat 5. The top front side of the sliding seat 5 is fixedly connected to the support base 7. The screw 8 is rotatably arranged on the support base 7, and the guide rod 9 is fixedly connected to the support base 7. The bottom of the support base 7... A servo motor 10 is mounted on the right side. A pulley assembly 11 is jointly provided on the output shaft of the servo motor 10 and the right end of the screw 8. The pulley assembly 11 consists of two pulleys and a belt. A mounting base 12 is threaded onto the screw 8 and slides on the guide rod 9. A mounting plate 13 is mounted on the front side of the mounting base 12, and an electric slide rail 14 is provided on the front side of the mounting plate 13. An electric slider 15 is mounted on the electric slide rail 14 and is fixedly connected to the nozzle 20. The assembly also includes a fixing frame 21, a sliding rod 22, a sealing plug 23, and a tension spring 2301. The nozzle 2... The internal fixed connection is a fixed frame 21, and a sliding rod 22 is slidably installed on the fixed frame 21. A sealing plug 23 is fixedly connected to the bottom of the sliding rod 22. A tension spring 2301 is sleeved on the sliding rod 22. The two ends of the tension spring 2301 are connected to the fixed frame 21 and the sealing plug 23 respectively. A fixed buckle 19 is fixedly connected to the right side of the mounting base 12. The delivery pipe 17 passes through the fixed buckle 19 to ensure that the delivery pipe 17 is firmly fixed. A silicone valve 26 is installed inside the spray pipe 2001. It automatically closes in the absence of pressure to form a double seal, which effectively prevents residual mold release agent from dripping from the nozzle 25 due to gravity. The top of the storage box 16 is covered with a sealing cap 27 to prevent the mold release agent in the storage box 16 from being contaminated or volatilized.

[0022] When the device is needed, the pipeline pump 18 is first started to deliver the release agent in the storage tank 16 to the nozzle 20 through the delivery pipe 17. The pressure of the release agent pushes the sliding rod 22 and the sealing plug 23 downward, opening the channel at the bottom of the nozzle 20. At this time, the tension spring 2301 is stretched, and the release agent is atomized and sprayed out through the nozzle 25 after passing through the spray pipe 2001, achieving uniform spraying. During the spraying process, the electric push rod 6 is started to control the piston rod to extend and retract, pushing the sliding seat 5 to move back and forth along the guide rail 4; the output shaft of the servo motor 10 rotates, driving the screw 8 to rotate through the pulley assembly 11, driving the mounting seat 12 to move left and right along the guide rod 9; the electric slide rail 14 operates, driving the sprayer through the electric slider 15. The nozzle 20 moves vertically, and through the coordinated work of three sets of drive mechanisms, the spatial movement flexibility of the nozzle 20 is improved, realizing multi-directional and automated spray coverage of the release agent. After the spraying operation is completed, the pipeline pump 18 stops working, and the pressure inside the nozzle 25 drops rapidly. At this time, the sliding rod 22 moves automatically upward under the action of the tension spring 2301, driving the sealing plug 23 to block the liquid outlet at the bottom of the nozzle 20, blocking the downward flow of the release agent, thereby effectively preventing residual release agent from dripping from the nozzle 25. When the next spraying starts and the pressure inside the nozzle 20 rises, the liquid flow pushes the sealing plug 23 to move downward against the tension of the tension spring 2301, while opening the silicone valve 26, opening the channel, and restoring the spraying function.
