Description

Technical Field

[0001] This utility model relates to the field of Dacromet surface treatment technology, and in particular to a spin-drying device for a coating machine. Background Technology

[0002] In the Dacromet coating process, the workpiece to be coated is placed in a stencil, which is then placed in a dip coating tank to dip the workpiece in. After dipping, the workpiece and the stencil are placed together in a spin dryer. The stencil is placed on an inner rack, and the coating is evenly applied to the workpiece by rotation. Excess liquid is quickly and effectively spun out. Finally, the stencil is hoisted onto a discharge rack to unload the parts.

[0003] Patent application CN213967490U discloses a spin-drying device for a coating machine for Dacromet coatings, including a support frame, a motor located on one side of the support frame, a horizontally arranged outer barrel on the support frame, and a clamping seat fixed to the inner and outer sides of the outer barrel on the support frame, with a roller abutting against the outer barrel inside the clamping seat.

[0004] This device spins the workpiece dry in the swirl tank, causing the accumulated liquid to be ejected and improving the coating quality. The Dacromet coating liquid ejected from the workpiece flows into the outer tank and then along the tank wall towards the center, achieving a concentration effect. Finally, it flows out from the outlet in the center. However, during this process, a large amount of coating liquid remains on the outer tank wall and cannot be completely drained, causing some coating liquid to remain on the inner wall. This will form an uneven coating after drying, requiring manual cleaning and increasing the difficulty of cleaning. To address the above problems, we have introduced a spin-drying device for coating machines. Utility Model Content

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0023] The spin-drying equipment of the coating machine disclosed in this utility model is mainly used in the Dacromet surface treatment scenario.

[0024] Reference Figures 1 to 4 A spin-drying device for a coating machine includes: two mounting plates 1, a connecting plate 2 fixedly connected between one side of the two mounting plates 1, a housing 3 fixedly connected between one side of the mounting plates 1, a cover plate 4 rotatably connected to one side of the housing 3, two rotating rods 5 rotatably connected inside the housing 3, a spin-drying rack 6 provided on one side of the two rotating rods 5, a flip cover 8 rotatably connected to the top of the spin-drying rack 6, two first mounting blocks 7 fixedly connected to the outside of the rotating rods 5, the two first mounting blocks 7 being fixed to one side of the spin-drying rack 6 by screws, a second mounting block 9 fixedly connected to one side of the spin-drying rack 6 and the flip cover 8, a first bolt 10 provided inside the second mounting block 9, a cleaning component provided on the outside of the rotating rods 5, a collection groove 11 opened at the bottom of the inner wall of the housing 3, a discharge port 12 fixedly connected to the bottom of the housing 3, a collection frame 13 provided at the bottom of the connecting plate 2, and a driving component provided on one side of the mounting plate 1, the driving component being used to drive one of the rotating rods 5 to rotate.

[0025] In the above technical solution, considering that a large amount of coating liquid will still remain on the outer barrel wall and cannot be completely drained, resulting in some coating liquid remaining on the inner wall, this will form an uneven coating after drying, requiring manual cleaning and increasing the difficulty of cleaning. To solve this problem, the specific operation is as follows: By setting a drive component to drive one of the rotating rods 5 to rotate, and using two rotating rods 5 to rotately connect with the outer shell 3, the spin dryer 6 will rotate inside the outer shell 3 to spin dry the workpiece in the spin dryer 6, so that the coating liquid is thrown onto the inner wall of the outer shell 3 and then flows into the collection tank 11. Since there is still a large amount of coating liquid on the inner wall, the cleaning component is used. The rotating rod 5 drives the cleaning component to scrape the inner wall of the outer shell 3, scraping the coating liquid into the collection tank 11, and finally discharging it into the collection frame 13 through the discharge port 12. The cleaning component cleans the coating liquid on the inner wall in time, ensuring that the inside of the outer shell 3 remains clean and free of residue after each spin dry, reducing the need for manual cleaning of the inner wall, saving time and labor costs, and improving operating efficiency.

[0026] Reference Figures 1 to 4 In a preferred embodiment, the cleaning assembly includes two fixing blocks 14 slidably connected to the outside of the rotating rod 5. A third mounting block 15 is fixedly connected to both the top and bottom of each fixing block 14. A second bolt 16 is disposed inside the third mounting block 15. A fixing plate 17 is fixedly connected to one side of each fixing block 14. The cleaning assembly also includes a receiving groove 18, which is formed on one side of the fixing plate 17. A limiting block 19 is slidably connected inside the receiving groove 18. A mounting rod 20 is fixedly connected to one side of the limiting block 19, with one end of the mounting rod 20 extending to the outside of the fixing plate 17 and fixed. A fourth mounting block 21 is fixedly connected to the fixed block 19. A spring 23 is provided between one side of the limiting block 19 and one side of the inner wall of the receiving groove 18. A scraper 22 is provided on one side of the fourth mounting block 21. The scraper 22 is fixed to the fourth mounting block 21 by screws. One side of the scraper 22 is in contact with the inner wall of the outer shell 3. Two limiting rings 24 are fixedly connected to the outer side of the rotating rod 5. One end of the two limiting rings 24 is slidably connected to the two sides of the fixed block 14. A positioning groove 25 is opened on the outer side of the rotating rod 5. A positioning block 26 is fixedly connected to one side of the fixed block 14. The outer side of the positioning block 26 is slidably connected to the inside of the positioning groove 25.

[0027] In the above technical solution, considering that a large amount of coating liquid will still remain on the outer barrel wall and cannot be completely drained, resulting in some coating liquid remaining on the inner wall, this will form an uneven coating after drying, requiring manual cleaning and increasing the difficulty of cleaning. To solve this problem, the specific operation is as follows: use screws to fix the scraper 22 to the fourth mounting block 21, then put the cleaning component into the outer shell 3, place multiple fixing blocks 14 on the rotating rod 5 between the limiting blocks 19, insert the positioning block 26 into the positioning groove 25 to make the two fixing blocks 14 fit together, and then use the second bolt 16. Two third mounting blocks 15 are fixed, thereby mounting the fixing block 14 on the rotating rod 5. The spring 23 causes the scraper 22 to abut against the inner wall of the outer casing 3. During the spin-drying process, the rotating rod 5 drives the fixing block 14 to rotate. Through the fixing plate 17 and the mounting rod 20, the scraper 22 is driven to rotate, thereby scraping the inner wall of the outer casing 3 and the cover plate 4, scraping the coating liquid into the collection tank 11, and finally collecting it through the discharge port 12. By cleaning the coating liquid in time, damage to the equipment caused by the drying of the coating liquid can be avoided, and failures caused by the accumulation of dirt can be reduced, thereby extending the service life of the equipment.

[0028] Reference Figures 1 to 4 In a preferred embodiment, the drive assembly includes a motor 27, which is disposed on one side of one of the mounting plates 1. A pulley 28 is provided on the outer side of one of the rotating rods 5 and the output shaft of the motor 27, and a belt 29 is disposed inside the pulley 28. A clamping rod 30 is rotatably connected to one side of one of the mounting plates 1, and the outer side of the clamping rod 30 abuts against the bottom of the belt 29. By starting the motor 27, the pulley 28, the belt 29 and the clamping rod 30 are used to drive one of the rotating rods 5 to rotate. The rotation relationship between the two rotating rods 5 and the outer casing 3 drives the spin dryer 6 to rotate, spin dry the workpiece, and at the same time drives the scraper 22 to rotate to clean the inner wall.

[0029] Working principle: In use, first use screws to fix the scraper 22 to the fourth mounting block 21, then put the cleaning assembly into the outer shell 3, place multiple fixing blocks 14 on the rotating rod 5 between the limiting blocks 19, insert the positioning block 26 into the positioning groove 25 to make the two fixing blocks 14 fit together, and then fix the two third mounting blocks 15 with the second bolt 16, thereby installing the fixing blocks 14 on the rotating rod 5. The spring 23 makes the scraper 22 abut against the inner wall of the outer shell 3. When the spin-drying is performed, the motor 27 is started, and the pulley 28, belt 29 and clamping rod 30 are used to drive one of the rotating rods 5 to rotate. The rotation relationship between the two rotating rods 5 and the outer shell 3 drives the spin-drying rack 6 to rotate, spin-drying the workpiece, and at the same time driving the scraper 22 to rotate and clean the inner wall, scraping the coating liquid into the collection tank 11, and finally discharging it into the collection frame 13 through the discharge port 12. The contents not described in detail in this specification are all prior art known to those skilled in the art.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
