Description

Technical Field

[0001] This utility model relates to the field of mixing tank cleaning technology, specifically a paint mixing tank with internal automatic cleaning. Background Technology

[0002] Paint mixing tanks are industrial equipment used for mixing materials in the paint industry. They achieve uniform mixing of paint through mechanical structure. After the paint is mixed, cleaning the mixing tank is a key step in paint production to ensure material purity and avoid cross-contamination. Its core objective is to efficiently remove residual materials from the inner wall of the mixing tank to ensure the cleanliness of the equipment to meet the needs of continuous production. However, the limitations of scraper disassembly in existing technology directly restrict the cleaning effect of the mixing tank.

[0003] However, in existing technologies, scrapers and components such as stirring rods and stirring blades are mostly connected by rigid methods such as welding. When scrapers need to be replaced due to wear and tear from long-term use, the welding points between the scraper and the stirring device must be destructively disassembled to remove the old scraper. This process can easily damage related components such as stirring rods and stirring blades, which not only significantly increases maintenance costs but also prolongs equipment downtime due to the time-consuming disassembly. To address these issues, we provide an internally automatically cleaning paint mixing tank. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a paint mixing tank with internal automatic cleaning.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an internally automatically cleaning paint mixing tank, comprising a device tank and a sealing cover. The outer wall of the device tank is threadedly connected to the inner wall of the sealing cover, and a servo motor is fixedly connected to the top of the sealing cover. A stirring rod is fixedly connected to the output end of the servo motor. The top of the stirring rod is rotatably connected to the inside of the sealing cover, and multiple stirring blades are fixedly connected to the outer wall of the stirring rod. Multiple mounting seats are fixedly connected to the bottom of the device tank, and universal wheels are fixedly connected to the bottom of the mounting seats. An inlet pipe and an outlet pipe are fixedly connected to the device tank, with the inlet pipe located above the outlet pipe. A set of vertically symmetrical telescopic mechanisms are fixedly connected to the outer wall of the stirring rod, and one end of the telescopic mechanism is engaged with an installation mechanism. A scraper is fixedly connected to one end of the installation mechanism.

[0006] The aforementioned installation mechanism includes a locking block, an insert block, a fixing block, bolts, and nuts. The bottom of the locking block is fixedly connected to the top of the insert block, and one end of the locking block is fixedly connected to one end of the fixing block. The outer walls of both bolts are threaded to the inside of the insert block, and one end of the bolts is threaded to the inside of the nut.

[0007] As described above, the card block has a T-shaped structure, and the end of the fixing block away from the card block is fixedly connected to one side of the scraper.

[0008] As mentioned above, the side of the scraper away from the block is in close contact with the inner wall of the device barrel.

[0009] The telescopic mechanism described above includes a mounting column, a spring, and a movable block. One end of the spring is fixedly connected to the interior of the mounting column, and the other end of the spring is fixedly connected to one end of the movable block.

[0010] As described above, two guide blocks are fixedly connected to both sides of the movable block, and one side of the guide block is slidably connected to the inner wall of the mounting column.

[0011] As described above, both the locking block and the insert block are inserted into the interior of the moving block, and one end of the bolt passes through the moving block and the insert block in sequence and extends to the outside of the moving block.

[0012] Compared with existing technologies, this internally automatically cleaning paint mixing tank has the following advantages: I. This utility model uses bolts and nuts to detach the locking block and insert block from the moving block, thereby removing the scraper from the telescopic mechanism. This operation method allows the old scraper to be removed without destructive disassembly of the welding points, reducing the additional replacement costs caused by component damage, shortening the scraper replacement time, and improving the continuous operation efficiency of the equipment.

[0013] Second, this utility model achieves dynamic adaptive contact between the scraper and the inner wall by using the elastic pressure of the spring, which can avoid scraper deformation or inner wall scratches caused by rigid contact, and can efficiently scrape off the material attached to the inner wall.

[0014] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0017] 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.

[0018] like Figure 1-5 As shown, this utility model provides a technical solution: an internally automatically cleaning paint mixing tank, including a device tank 1 and a sealing cover 2. The outer wall of the device tank 1 is threadedly connected to the inner wall of the sealing cover 2, and a servo motor 3 is fixedly connected to the top of the sealing cover 2. A stirring rod 4 is fixedly connected to the output end of the servo motor 3. The top of the stirring rod 4 is rotatably connected to the inside of the sealing cover 2, and multiple stirring blades 5 are fixedly connected to the outer wall of the stirring rod 4. Multiple mounting seats 6 are fixedly connected to the bottom of the device tank 1, and universal wheels 7 are fixedly connected to the bottom of the mounting seats 6. A water inlet pipe 8 and a water outlet pipe 9 are fixedly connected to the device tank 1, and the water inlet pipe 8 is located above the water outlet pipe 9. A set of vertically symmetrical telescopic mechanisms 10 are fixedly connected to the outer wall of the stirring rod 4, and one end of the telescopic mechanism 10 is engaged with an installation mechanism 11. A scraper 12 is fixedly connected to one end of the installation mechanism 11.

[0019] First, connect the electrical components to an external power source and electrically connect them to the controller. Next, deliver water and cleaning agent into the device tank 1 through the water inlet pipe 8. Then, start the servo motor 3 via the controller, causing it to drive the stirring rod 4 to rotate. At this time, the stirring blades 5 on the stirring rod 4 further mix the water and cleaning agent. Simultaneously, the stirring rod 4 rotates, driving the scraper 12 to rotate synchronously via the telescopic mechanism 10. The elastic force of the spring 1002 compresses the telescopic mechanism 10, causing it to move along the trajectory of the guide block 13. The telescopic mechanism 10 then compresses the scraper 12, ensuring it remains in contact with the inner wall of the device tank 1. Through the elastic pressure of the telescopic mechanism 10, the scraper 12... 2. The dynamic adaptive fit with the inner wall avoids deformation of the scraper 12 or scratches on the inner wall caused by rigid contact, and can efficiently scrape off the material attached to the inner wall. Finally, if it is necessary to disassemble the scraper 12, rotate the sealing cover 2 so that the sealing cover 2 drives the stirring rod 4 and the telescopic mechanism 10 and the installation mechanism 11 on the stirring rod 4 to move out of the device barrel 1 at the same time. Then, rotate the installation mechanism 11 so that the installation mechanism 11 moves out from the inside of the telescopic mechanism 10. At this time, the scraper 12 can be removed. This operation method can remove the old scraper 12 without destructive disassembly of the welding point, reducing the additional replacement cost caused by component damage, shortening the scraper 12 replacement time and improving the continuous operation efficiency of the equipment.

[0020] like Figure 1 , Figure 2 and Figure 5 As shown, the installation mechanism 11 includes a locking block 1101, an insert block 1102, a fixing block 1103, bolts 1104, and nuts 1105. The bottom of the locking block 1101 is fixedly connected to the top of the insert block 1102, and one end of the locking block 1101 is fixedly connected to one end of the fixing block 1103. The outer walls of the two bolts 1104 are threaded to the inside of the insert block 1102, and one end of the bolts 1104 is threaded to the inside of the nut 1105. The locking block 1101 has a T-shaped structure. The end of the fixing block 1103 away from the locking block 1101 is fixedly connected to one side of the scraper 12. The side of the scraper 12 away from the locking block 1101 is in close contact with the inner wall of the device barrel 1.

[0021] If scraper 12 needs to be disassembled, rotate sealing cover 2 to move the stirring rod 4, the telescopic mechanism 10 on the stirring rod 4, and the installation mechanism 11 from the device barrel 1. Then, rotate nut 1105 to disengage from bolt 1104. Then, disengage bolt 1104 from insert block 1102 and moving block 1003. At this time, remove insert block 1102 and locking block 1101 from the inside of moving block 1003. At this time, locking block 1101 is removed from scraper 12 through fixing block 1103. This operation method can remove old scraper 12 without destructive disassembly of welding points, reducing the additional replacement cost caused by component damage, shortening scraper 12 replacement time, and improving the continuous operation efficiency of equipment.

[0022] like Figure 1 , Figure 2 and Figure 5 As shown, the telescopic mechanism 10 includes a mounting post 1001, a spring 1002, and a moving block 1003. One end of the spring 1002 is fixedly connected to the interior of the mounting post 1001, and the other end of the spring 1002 is fixedly connected to one end of the moving block 1003. Two guide blocks 13 are fixedly connected to both sides of the moving block 1003, and one side of the guide block 13 is slidably connected to the inner wall of the mounting post 1001. The locking block 1101 and the insert block 1102 are both inserted into the interior of the moving block 1003. One end of the bolt 1104 passes through the moving block 1003 and the insert block 1102 in sequence and extends to the outside of the moving block 1003.

[0023] While the stirring rod 4 is rotating, the scraper 12 is driven to rotate synchronously through the telescopic mechanism 10. At this time, the spring 1002 squeezes the moving block 1003, causing the moving block 1003 to move along the guide block 13 within the mounting column 1001. Then, the moving block 1003 squeezes the scraper 12 through the mounting mechanism 11, so that the scraper 12 always adheres to the inner wall of the device barrel 1. With the help of the elastic pressure of the spring 1002, the scraper 12 and the inner wall are dynamically and adaptively adhered, which can avoid the deformation of the scraper 12 or scratches on the inner wall caused by rigid contact, and can efficiently scrape off the material attached to the inner wall.

[0024] Working Principle: First, connect the electrical components to an external power source and electrically connect them to the controller. Then, water and detergent are delivered into the device tank 1 through the water inlet pipe 8. Next, the servo motor 3 is started by the controller, causing the servo motor 3 to drive the stirring rod 4 to rotate. At this time, the stirring blades 5 on the stirring rod 4 stir and mix the water and detergent again. While the stirring rod 4 is rotating, the scraper 12 is driven to rotate synchronously through the telescopic mechanism 10. At this time, the elastic force of the spring 1002 presses the moving block 1003, causing the moving block 1003 to move along the guide block 13 within the mounting column 1001. Then, the moving block 1003 presses the scraper 12 through the mounting mechanism 11, so that the scraper 12 always adheres to the inner wall of the device tank 1. With the help of the elastic pressure of the spring 1002, the scraper 12 and the inner wall are dynamically and adaptively adhered, which avoids rigid contact. The scraper 12 can be deformed or scratched on the inner wall due to contact, but it can also efficiently scrape off the material attached to the inner wall. Finally, if it is necessary to disassemble the scraper 12, rotate the sealing cover 2 so that the sealing cover 2 drives the stirring rod 4 and the telescopic mechanism 10 and the installation mechanism 11 on the stirring rod 4 to move out of the device barrel 1 at the same time. Then, rotate the nut 1105 so that the nut 1105 is disengaged from the bolt 1104. Then, the bolt 1104 is disengaged from the insert block 1102 and the moving block 1003. At this time, the insert block 1102 and the locking block 1101 are moved out of the inside of the moving block 1003. At this time, the locking block 1101 is disassembled from the scraper 12 through the fixing block 1103. This operation method can remove the old scraper without destructively disassembling the welding point, which reduces the additional replacement cost caused by component damage, shortens the scraper replacement time, and improves the continuous operation efficiency of the equipment.
