Description

Technical Field

[0001] This utility model relates to the field of coating production technology, and in particular to a material feeding device for coating production. Background Technology

[0002] Paint production is an industrial activity that uses resins, pigments, solvents, and additives as main raw materials and mixes them according to scientific formulas. Through a series of processes such as dispersion, grinding, and stirring, the various raw materials are fully integrated and meet the specified performance indicators, ultimately producing paint products with functions such as protection, decoration, and marking, which are widely used in many fields such as construction, automobiles, and ships.

[0003] The feeding device for paint production is used to transport various raw materials required for paint production from storage containers to processing equipment in a certain quantity and speed. Common types include funnels, multi-channel feeding devices, and quantitative feeding mechanisms. Pneumatic feeding devices use negative or positive pressure generated by a fan to suck or press raw materials out of the storage bin and transport them to a designated location through a conveying pipeline, such as the feeding device for a carbon black suction machine. Rotary feeding devices use a motor to drive the gear ring and feed hopper to rotate, which in turn drives the feed hopper to rotate synchronously, allowing the feeding position to be adjusted in the horizontal and circumferential directions. Quantitative feeding devices, such as the quantitative feeding device from Jiangsu Rentong, use the cooperation of a motor, synchronous belt, synchronous shaft, and quantitative roller to make the material fall into the mixing tank in a certain amount as the quantitative roller rotates.

[0004] In existing technologies, some coating production feeding devices suffer from problems due to the complex composition of coatings, which include resins, pigments, additives, and other substances. During the raw material feeding process, these substances easily adhere to the inner wall of the feeding device. Over time, the deposits on the inner wall become increasingly thick, leading to unstable feeding speeds and consequently affecting the efficiency of coating production. This results in deviations in the coating's color, stability, and other performance indicators. Therefore, a new feeding device for coating production is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a feeding device for paint production, which aims to improve the problem of unstable feeding speed in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A material feeding device for paint production includes a housing 1, a base plate fixedly connected to the inner wall of the housing 1, a spring 1 fixedly connected to the top of the base plate, a housing 2 fixedly connected to the top of the spring 1, a plurality of cleaning grooves opened inside the housing 2, a slider 1 slidably connected inside the cleaning grooves, a spring 2 fixedly connected to the bottom of the slider 1, a filter screen fixedly connected to adjacent sides of the plurality of slider 1s, a plurality of connecting blocks fixedly connected to the outside of the filter screens, a spring 3 fixedly connected to the rear inner wall of one of the connecting blocks, a connecting block fixedly connected to the front side of the spring 3, a cleaning ring fixedly connected to the front of the connecting block, a spring 4 fixedly connected to the left inner wall of the cleaning ring, a connecting ring fixedly connected to the right side of the spring 4, and two metering components for facilitating quantitative measurement rotatably connected to the top of the housing 2.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the force of the raw material drives the filter screen to descend, which in turn drives the cleaning ring to descend and clean the inner wall. The cleaning ring is cushioned by the spring through the connecting block, thereby realizing the use of the raw material to drive the filter screen to descend and the cleaning ring to clean the inner wall of the housing. When encountering impurities that are difficult to remove, the cleaning ring is protected by the spring buffer.

[0032] 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.

[0033] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a material feeding device for paint production, comprising a housing 1, which provides installation space and protection for internal components. A base plate 2 is fixedly connected to the inner wall of the housing 1, and the base plate 2 provides fixation and support for a spring 3. A spring 3 is fixedly connected to the top of the base plate 2, and the spring 3, being elastic, provides elastic support for the housing 4. After the liquid inside the housing 4 is discharged, the spring 3 can push the housing 4 back to its original position by its own elastic return. The top of the spring 3 is fixedly connected to the housing 4, which is used to hold raw materials. Multiple cleaning grooves 5 are provided inside the housing 4, and the cleaning grooves 5 provide guidance and limiting for a slider 6. A slider 6 is slidably connected inside the cleaning grooves 5, and the slider 6 provides guidance and limiting for a filter screen 12. A spring 7 is fixedly connected to the bottom of the slider 6, and the spring 7, being elastic, provides elastic support for the slider 6. After the force is applied, the spring 7 can push the slider 6 back to its original position by its own elastic return.

[0034] Multiple sliders 6 are fixedly connected to adjacent sides of a filter screen 12, which is used to filter the flowing raw material. Multiple connecting blocks 8 are fixedly connected to the outside of the filter screen 12, providing fixation and support for the connecting blocks 8. A spring 9 is fixedly connected to the rear inner wall of one of the connecting blocks 8, providing elastic support for its connecting block 10. A connecting block 10 is fixedly connected to the front of the spring 9, connecting the cleaning ring 11 and the connecting block 8. A cleaning ring 11 is fixedly connected to the front of the connecting block 10, used for cleaning the interior of the housing 4. A spring 13 is fixedly connected to the left inner wall of the cleaning ring 11, providing elastic support for its connecting ring 14. A connecting ring 14 is fixedly connected to the right side of the spring 13. When the cleaning ring 11 encounters impurities that are difficult to clean in one pass, the connecting ring 14 is buffered by the spring 9 and then resets better. Two metering components are rotatably connected to the top of the housing 4 for easy metering.

[0035] Reference Figure 2 and Figure 5 The metering component includes a connecting plate 15, which connects the housing 4 and the baffle 17. Two fixing blocks 16 are fixedly connected to the top inner wall of the housing 1, providing guidance and limiting for the baffle 17. Two baffles 17 are slidably connected to adjacent sides of the two fixing blocks 16. As the liquid inside the housing 4 gradually increases or decreases, the connecting plate 15 pulls the baffles 17 to block the discharge port, thus completing the metering. A drain pipe 18 is fixedly connected to the bottom of the housing 4, used to discharge the internal raw materials. A flow meter 19 is fixedly connected to the outside of the drain pipe 18, measuring the outflowing raw materials. When a certain flow rate is reached, the flow meter 19 sends a signal to the cylinder 21, causing its limiting block 22 to disengage from the limiting groove 20. The housing 4 then rises due to the elastic reset of the spring 3.

[0036] Reference Figures 1 to 3 The inner surface of housing 24 has a limiting groove 20, which cooperates with the limiting block 22 to limit and fix housing 24. A trigger button 25 is fixedly connected to the top of the base plate 2. When housing 24 descends and touches the trigger button 25, it transmits a signal to the cylinder 21. A cylinder 21 is fixedly connected to the inner wall of housing 1. The cylinder 21 drives the limiting block 22 to move. The driving end of the cylinder 21 is fixedly connected to the limiting block 22, so that the limiting block 22 is engaged in the limiting groove 20 to limit and fix housing 24. Two guide posts 23 are fixedly connected to the inner wall of housing 1. The guide posts 23 guide and limit the guide block 24.

[0037] Multiple guide blocks 24 are fixedly connected to the exterior of housing 2 4. The guide blocks 24 are used to guide and limit housing 2 4. The exterior of connecting block 10 is slidably connected to the interior of connecting block 8. Connecting block 8 provides guidance and limitation for connecting block 10. The exterior of connecting ring 14 is slidably connected to the interior of cleaning ring 11. Cleaning ring 11 provides guidance and limitation for connecting ring 14. The bottom of spring 2 7 is fixedly connected to the bottom inner wall of cleaning groove 5. Cleaning groove 5 provides fixation and support for spring 2 7. The exterior of limiting block 22 is in contact with the inner wall of limiting groove 20. Similarly, limiting groove 20 and limiting block 22 cooperate to limit and fix housing 2 4. The top of connecting plate 15 is rotatably connected to the bottom of baffle 17. Connecting plate 15 receives the pulling force from housing 2 4 when it descends, thereby pulling baffle 17 to move. The bottom of connecting plate 15 is rotatably connected to the top of housing 2 4. When housing 2 4 descends, it drives connecting plate 15 to move synchronously.

[0038] Working principle: When in use, the raw material flows into the interior of the housing 4 through the feed port of housing 1. The filter screen 12 filters the flowing raw material. During the filtration process, if impurities adhere to the inner wall of housing 4, the force of the raw material will cause the filter screen 12 to descend, which in turn will cause the cleaning ring 11 to descend and clean the inner wall. When the cleaning ring 11 encounters impurities that are difficult to remove in one go, the cleaning ring 11 is pressed and buffered by the spring 9 through the connecting block 10, thereby protecting the cleaning ring 11 from damage. At the same time, the spring 13 provides elastic support for the connecting ring 14, which further assists the cleaning work. The slider 6 slides in the cleaning groove 5. After the spring 7 is exhausted, it pushes the slider 6 to reset, which in turn drives the filter screen 12 and the cleaning components to reset, ensuring that the filter screen 12 and the cleaning ring 11 can continuously and stably perform cleaning and filtration operations.

[0039] Raw materials enter the housing 4. As the liquid inside the housing 4 gradually increases, the weight of the raw materials causes the housing 4 to descend, compressing the spring 3. As the housing 4 descends, the connecting plate 15 pulls the baffle 17. The baffle 17 slides within the fixed block 16, gradually blocking the discharge port to achieve initial quantitative control. When the housing 4 descends and touches the trigger button 25, the trigger button 25 transmits a signal to the cylinder 21. The cylinder 21 drives the limit block 22 to engage with the limit groove 20, completing the limit fixation of the housing 4 and accurately controlling the discharge amount. The discharge pipe 18 discharges the raw materials, and the flow meter 19 measures the outflowing raw materials. When a certain flow rate is reached, the flow meter 19 transmits a signal to the cylinder 21, and the limit block 22 disengages from the limit groove 20. At this time, the spring 3 elastically resets and pushes the housing 4 upward.

[0040] 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.
