Description

Technical Field

[0001] This utility model relates to the field of metal product processing equipment technology, and in particular to a raw material mixing device for metal product spraying processing. Background Technology

[0002] In the spray coating process of metal products, the uniform mixing and precise proportioning of raw materials directly determine the key properties of the coating, such as adhesion, corrosion resistance, and gloss. The characteristics of the raw materials used in metal product spray coating place strict requirements on the mixing process. The raw material system used for metal product spray coating is complex. In addition to the initially added film-forming base material (such as epoxy resin and acrylic resin), it is often necessary to add secondary mixtures during the mixing process according to the coating requirements.

[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: Existing mixing tanks generally suffer from the technical shortcoming of lacking a precise quantity control structure when adding mixtures for the second time. Most devices rely solely on manual addition through funnels or simple conduits, lacking visual quantitative references and mechanical fixing structures. Workers need to estimate the amount to be added based on experience, which can easily lead to excessive or insufficient mixture due to visual errors or shaky hands. For example, excessive addition of hardener during the second time will cause the mixed raw materials to gel prematurely, making normal spraying impossible; insufficient addition will prolong the coating drying time and affect production efficiency. Utility Model Content

[0004] The technical problem this utility model aims to solve is that existing technologies generally lack precise quantity control structures when adding materials to mixing tanks for the second time. Most of the time, the materials are added manually through funnels or simple conduits, without visual quantitative references or mechanical fixing structures. Workers rely on experience to estimate, which can easily lead to excessive or insufficient mixing due to visual errors or shaky hands. For example, adding too much curing agent will cause the mixed raw materials to gel prematurely and become unusable for spraying, while adding too little will prolong the coating drying time and affect production efficiency. To address this, we propose a raw material mixing device for metal product spraying.

[0005] To achieve the above objectives, this application adopts the following technical solution: a raw material mixing device for metal product spraying, comprising four support columns, a mixing tank fixedly connected to the upper end of the four support columns, a top cover movably installed on the upper end of the mixing tank, a motor installed on the upper end of the top cover, a connecting pipe connected to the arc surface of the mixing tank, a scale chamber fixedly connected to one end of the connecting pipe, a circular hole opened on the bottom surface of the inner wall of the scale chamber, the circular hole communicating with one end of the connecting pipe, a slider slidably inserted in the scale chamber, a circular block fixedly connected to one side of the slider, the size of the circular block matching the size of the circular hole, a square hole opened on the upper surface of the slider, a mounting frame fixedly connected to the arc surface of the scale chamber, a square block slidably connected to the inner wall of the mounting frame, the size of the square block matching the size of the square hole, a connecting rod slidably inserted in the mounting frame, one end of the connecting rod fixedly connected to the square block.

The size of the fixing block is adapted to the size of the inner wall of the installation block, a slot is provided on one side of the fixing block, and a plug rod is slidably inserted into the installation block, with the plug rod slidably connected to the inner wall of the slot.

[0021] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0022] reference Figures 1-5As shown, this utility model provides a technical solution: a raw material mixing device for metal product spraying processing, including four support columns 1, a mixing tank 2 fixedly connected to the upper end of the four support columns 1, a top cover 3 movably installed on the upper end of the mixing tank 2, a motor 4 installed on the upper end of the top cover 3, a connecting pipe 5 connected to the arc surface of the mixing tank 2, a scale chamber 6 fixedly connected to one end of the connecting pipe 5, a circular hole 7 opened on the bottom surface of the inner wall of the scale chamber 6, the circular hole 7 connected to one end of the connecting pipe 5, a slider 8 slidably inserted in the scale chamber 6, a circular block 9 fixedly connected to one side of the slider 8, the size of the circular block 9 matching the size of the circular hole 7, a square hole 10 opened on the upper surface of the slider 8, a mounting frame 11 fixedly connected to the arc surface of the scale chamber 6, a square block 12 slidably connected to the inner wall of the mounting frame 11, the size of the square block 12 matching the size of the square hole 10, a connecting rod 13 slidably inserted in the mounting frame 11, one end of the connecting rod 13 fixedly connected to the square block 12. By using the graduated chamber 6 and related components, operators can accurately add materials a second time. When the required mixture needs to be added for mixing, the staff can visually observe through the graduated chamber 6 and use the slider 8, round block 9 and other structures inside the graduated chamber 6 to control the amount of mixture flowing into the mixing tank 2 through the round hole 7 and connecting pipe 5. This avoids resource waste due to over-addition or under-addition that fails to meet the required amount for mixing, ensuring mixing quality and spraying effect, making the production process more stable and efficient, reducing product quality fluctuations caused by raw material ratio errors, and facilitating the orderly development of metal product spraying. The bottom surface of the inner wall of the graduated chamber 6 is fixedly connected to the positioning plate 15, and the round block 9 is slidably connected to the inner wall of the positioning plate 15. The positioning plate 15 on the bottom surface of the inner wall of the scale chamber 6 is slidably connected to the round block 9, which can guide and limit the movement of the round block 9, so that the round block 9 can accurately block or open the round hole 7, ensuring the stability and accuracy of the quantitative addition of raw materials and improving the mixing accuracy. One end of the connecting rod 13 is fixedly connected to the round plate 14, and the arc surface of the connecting rod 13 is fitted with a spring 16. The two ends of the spring 16 are fixedly connected to the mounting frame 11 and the round plate 14 respectively.When the circular plate 14 is pulled, causing the connecting rod 13 and the square block 12 to move, and the square block 12 to disengage from the square hole 10 to adjust the position of the slider 8, the spring 16 is compressed. After adjustment, the pulling of the circular plate 14 is released, and the elastic force of the spring 16 can drive the square block 12 to automatically reset and insert into the square hole 10, quickly completing the fixation of the slider 8. The operation is convenient and can efficiently maintain the stability of the slider 8 position, ensuring the accuracy of the quantitative addition of raw materials. The arc surface of the scale chamber 6 is fixedly connected to the fixing bracket 17 for fixation. A fixing rod 18 is fixedly connected to the inner wall of the frame 17. A rotating block 19 is rotatably connected to the arc surface of the fixing rod 18. A protective plate 20 is fixedly connected to one side of the rotating block 19. A fixing block 21 is fixedly connected to the arc surface of the protective plate 20. An installation block 22 is fixedly connected to the arc surface of the scale chamber 6. The size of the fixing block 21 is adapted to the size of the inner wall of the installation block 22. A slot is provided on one side of the fixing block 21. An insert rod 23 is slidably inserted into the installation block 22. The insert rod 23 is slidably connected to the inner wall of the slot. Through the rotatable connection between the fixing rod 18 and the fixing frame 17, the protective plate 20 can be driven to cover the opening area of ​​the scale chamber 6, which can effectively block external dust and impurities from entering the interior of the scale chamber 6, prevent impurities from adhering to the sliding surface of the slider 8 or the round hole 7, and prevent the raw material flow and quantitative control accuracy from being affected by component jamming or blockage of the round hole 7, thus ensuring the long-term stable operation of the quantity control component. A sealing gasket 24 is fixedly connected to the arc surface of the protective plate 20. The sealing gasket 24 is made of silicone. The elasticity and conformability of the silicone sealing gasket 24 can fill the gap between the protective plate 20 and the scale chamber 6, further preventing paint droplets, metal dust, etc. from seeping in. The arc surface of the fixing rod 18 is fitted with two torsion springs, and the two ends of the torsion springs are fixedly connected to the fixing frame 17 and the rotating block 19, respectively. When the operator pulls the insertion rod 23 away from the slot to release the limitation on the fixing block 21, the torque of the torsion spring will drive the rotating block 19 and then drive the protective plate 20 to rotate and open automatically, improving the convenience of use. The lower end of the support column 1 is fixedly connected to a shock-absorbing pad 25, which is made of rubber. By setting the rubber shock-absorbing pad 25, the rubber material itself has a large coefficient of friction, which can increase the contact friction between the support column 1 and the ground, effectively preventing the device from shaking or displacing during the operation of the motor 4 and the mixing and stirring of raw materials.

[0023] Working principle: First, in the initial mixing stage of mixing tank 2, before operation, the rubber shock-absorbing pads 25 at the lower end of the four support columns 1 increase the contact friction with the ground due to their large coefficient of friction, laying the foundation for stable operation of the device in advance; when mixing tank 2 starts mixing operation, the top cover 3 at its upper end is opened, the initial raw materials are added into the tank, the top cover 3 is closed, and the motor 4 on the top cover 3 is started. The motor 4 outputs power to drive the stirring components inside the tank to rotate, and performs preliminary stirring of the initial raw materials. During this period, the shock-absorbing pads 25 continuously reduce the shaking caused by the operation of the motor 4, ensuring the stability of the stirring process.

[0024] Secondly, in the secondary addition stage of the mixture in mixing tank 2: when it is necessary to add the mixture to mixing tank 2 for the second time, first pull the insert rod 23 away from the slot of the fixing block 21 on the protective plate 20 to release the restriction on the protective plate 20; at this time, the torsion spring on the fixing rod 18 releases the torque, drives the rotating block 19 to rotate, and then the protective plate 20 opens automatically. The operator can directly observe the scale on the scale chamber 6 and add an appropriate amount of mixture into the scale chamber 6; then pull the round plate 14 at one end of the connecting rod 13, the round plate 14 drives the connecting rod 13 and the square block 12 to move, so that the square block 12 disengages from the square hole 10 on the slider 8 (during this process, the spring 16 on the arc surface of the connecting rod 13 is compressed); then slide the slider 8 to adjust the position until the round hole 7 on the bottom surface of the inner wall of the scale chamber 6 leaks out, and the mixture will flow precisely into the mixing tank 2 through the round hole 7 and the connecting pipe 5. After the second addition is completed, push the slider 8 to reset. The slider 8 drives the round block 9 to abut against the positioning plate 15 in the scale chamber 6. At this time, the slider 8 just blocks the round hole 7, stopping the flow of the mixture. At the same time, release the round plate 14. The spring 16 forces the square block 12 to reset and insert into the square hole 10, locking the position of the slider 8.

[0025] Finally, after the second addition operation is completed, rotate the protective plate 20 to cover the opening of the scale chamber 6, insert the fixing block 21 on the protective plate 20 into the mounting block 22 of the arc-shaped mounting bracket 11 of the scale chamber 6, and then insert the plug rod 23 to limit the fixing block 21, thus completing the fixation of the protective plate 20. The silicone sealing gasket 24 on the arc-shaped surface of the protective plate 20 will tightly fill the gap between the protective plate 20 and the scale chamber 6, effectively preventing dust and paint droplets in the workshop from seeping into the interior of the scale chamber 6.

[0026] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
