Description

Technical Field

[0002] Insulating powder coatings belong to high-performance environmentally friendly coatings, which are commonly used for insulating treatment of electrical equipment, providing excellent electrical insulation performance and heat resistance. In the production of insulating powder coatings, various raw materials are fully mixed in a mixing tank according to a certain ratio; In traditional technology, equipment cleaning mainly relies on manual operation, using tools such as water, chemical solvents, and brushes for cleaning. This method is not only time-consuming and laborious, but also difficult to ensure consistent cleaning effects, and it is easy to leave residues of powder or chemical substances, affecting subsequent production; for example, in the invention patent with the publication number CN108080381A, the rotating roller used can scrape the coating on the inner wall of the coating bucket during rotation, achieving the cleaning operation of the inner wall of the coating bucket; however, since the coating bucket itself is in a static state during cleaning, for coatings with strong adhesion or already cured coatings, the scraper is difficult to effectively remove and is likely to leave stubborn residues on the bucket wall; moreover, since the scraper cannot undergo elastic shrinkage changes during cleaning, its scraper angle is mostly fixedly set, resulting in hard contact with the inner wall of the coating bucket, which will cause increased wear of the scraper and the bucket wall after long-term use, increasing the risk of equipment maintenance costs and shortened service life; Therefore, it is necessary to provide an automatic cleaning device for production equipment for insulating powder coatings to solve the problems raised in the above background art.

Detailed implementation mode

[0014] Please refer to Figures 1 - 8 In the embodiment of the present invention, an automatic cleaning device for a production equipment for insulating powder coatings includes a gantry 11, with a base 1 fixed to its lower end face. A vibrating tank unit 2 is arranged in the middle of the base 1. A crossbeam 12 is horizontally arranged on the gantry 11, and sliding seats 13 are fixed to both ends of the crossbeam 12. The sliding seats 13 slide along the vertical direction of the gantry 11; A lower drive 14 is slidably installed on the crossbeam 12. The output end of the lower drive 14 is provided with a positioning plate 15, and a connecting frame 3 is horizontally fixed on the positioning plate 15; One end of the connecting frame 3 is vertically rotatably connected to a coupling shaft 31, and an industrial camera 32 is installed at the lower end of the coupling shaft 31. The industrial camera 32 mainly acquires images of the inside of the coating tank when the coupling shaft 31 gradually penetrates into the tank, so as to identify information such as the distribution and thickness of the residual coating on the inner wall of the coating tank. A cleaning liquid nozzle (not shown in the figure) can be installed on the coupling shaft 31, and the cleaning liquid nozzle can spray the pre-configured detergent onto the inner wall of the coating tank to soften the coating residue; The other end of the connecting frame 3 is vertically installed with a scraping mechanism 4. Before the cleaning work, the industrial camera 32 first extends into the paint tank to obtain images, and then the scraping mechanism 4 scrapes the paint in a suitable manner. Herein, the industrial camera 32 and the scraping mechanism 4 are adjusted vertically with the slide 13 on the cross beam 12, effectively controlling the industrial camera 32 and the scraping mechanism 4 to extend into or out of the paint tank. In the specific cleaning process, the cleaning is mainly divided into two steps: preliminary cleaning and fine cleaning. In the preliminary cleaning stage, the tank vibrating unit 2 can provide a vibrating effect on the paint tank to cooperate with the scraping mechanism 4 to efficiently scrape the residual paint on the inner wall of the paint tank. In the fine cleaning stage, the scraping mechanism 4 can be flexibly adjusted and perform a secondary scraping on the inner wall of the paint tank with higher precision. A flushing pipe can also be provided on the connecting frame 3 to flush the inner wall of the paint tank after the scraping cleaning of the inner wall of the paint tank is completed.

[0015] In this embodiment, the tank vibrating unit 2 includes: an X-axis plate 21 which is horizontally slidably installed on the base 1. A first spring is connected between the X-axis plate 21 and the base 1. A Y-axis plate 22 is slidably installed on the X-axis plate 21, and a second spring is connected between the X-axis plate 21 and the Y-axis plate 22. A protective seat 23 is fixed in the middle of the Y-axis plate 22. A notch for placing the paint tank is provided in the middle of the protective seat 23. A cylindrical ring 24 is concentrically arranged in the protective seat 23, and a plurality of inner springs are circumferentially distributed between the cylindrical ring 24 and the protective seat 23. An X-axis vibrator 25 is fixed on the base 1, and the output end of the X-axis vibrator 25 is connected to the X-axis plate 21. And a Y-axis vibrator 26 is fixed on the X-axis plate 21, and the output end of the Y-axis vibrator 26 is connected to the Y-axis plate 22. Thus, a multi-dimensional and compound high-frequency vibration effect can be provided for the paint tank in the cylindrical ring 24 during the synchronous working vibration of the X-axis vibrator 25 and the Y-axis vibrator 26. On the one hand, it can significantly improve the loosening of the paint residues on the inner wall of the paint tank, and on the other hand, it can cooperate with the scraping mechanism 4 to efficiently scrape the residues on the inner wall of the paint tank.

[0016] As a preferred embodiment, a carrier plate 27 is rotatably arranged in the protective seat 23, and a plurality of rollers 28 are distributed on the circumferential side wall of the cylindrical ring 24. Thus, the paint tank can be controlled to rotate slowly (the rotation direction is opposite to the working direction of the scraping mechanism 4) through the carrier plate 27 in the preliminary cleaning stage, further improving the cleaning efficiency and shortening the cleaning time.

[0017] In this embodiment, the scraping mechanism 4 includes: a main shaft 41, the upper end of which is rotatably connected to the connecting frame 3 through a bearing. Two collar rings 42 are symmetrically installed on the main shaft 41. A plurality of support rods 43 are circumferentially hinged on each collar ring 42. The other ends of the support rods 43 are rotatably connected with side lining blocks 44. A scraper 45 is vertically connected between two side lining blocks 44 in the same vertical line direction. Wherein, the lower end of the main shaft 41 can be installed with a bottom scraper (not shown in the figure) for scraping the coating residues at the bottom of the tank body. A driving motor 46 is fixed on the connecting frame 3. The output end of the driving motor 46 is connected and driven with the main shaft 41 through a transmission belt, so that the rotation of the main shaft 41 drives each scraper 45 to scrape and clean the inner wall of the coating tank.

[0018] In this embodiment, a guide groove 47 is formed on the side lining block 44, and two pins are fixed at the ends of the scraper 45. The pins are slidably connected with the guide groove 47.

[0019] In this embodiment, the guide groove 47 is composed of a straight line segment and an arc segment, and is arranged on the side away from the blade edge of the scraper 45 in the straight line segment. A limiting spring 48 is connected between the scraper 45 and the side lining block 44. In the initial cleaning stage, the pin is at the end of the arc segment of the guide groove 47, and the scraper 45 is inclined at 40° relative to the side lining block 44. When the can shaking unit 2 can provide a can shaking effect on the coating can, the inner wall of the coating can is in full contact with the scraper 45, and the scraper 45 can slide synchronously along the side lining block 44 with the vibration of the coating can. The sliding of the pin and the guide groove 47 makes the angle of the scraper 45 gradually decrease and gradually perpendicular to the inner wall of the coating can. Therefore, during the continuous vibration of the coating can, the scraper 45 can flexibly adjust the scraping angle and will not cause scratches to its inner wall, improving the scraping and cleaning effect.

[0020] As a preferred embodiment, a connecting frame 5 is fixed on the main shaft 41. A plurality of guide shafts 51 corresponding to the scraper 45 are circumferentially fixed on the connecting frame 5. Column arms 52 are slidably connected on the guide shafts 51. A fixing rod 53 is installed on the column arm 52. One end of the fixing rod 53 is connected to the blade body of the scraper 45. A rotating ring seat 54 is rotatably connected outside each guide shaft 51 on the connecting frame 5. A sleeve 55 is fixed on the rotating ring seat 54. One end of the sleeve 55 extends into and is connected to the column arm 52. A shaft pin is fixed on the outer wall of the sleeve 55. An arc-shaped groove is formed on the inner wall of the column arm 52. The shaft pin is slidably connected in the arc-shaped groove. Thus, during the forward and reverse rotation of the rotating ring seat 54, the column arm 52 can be driven to approach or move away from the connecting frame 5 through the sliding action of the shaft pin and the arc-shaped groove, so that the fixing rod 53 on the column arm 52 can freely slide radially. A disk seat 56 is slidably connected above the connecting frame 5 on the main shaft 41. A plurality of guide rods 57 are connected to the lower end of the disk seat 56. The other ends of the guide rods 57 are all connected to a hinge frame 58, and the other end of the hinge frame 58 is connected to the swivel seat 54.

[0021] In this embodiment, a shaft pressing plate 6 is slidably arranged on the main shaft 41. The lower part of the shaft pressing plate 6 is connected to the disk seat 56 through a plurality of compression springs. Therefore, in the preliminary cleaning stage, the disk seat 56 can be in a pressed state by the shaft pressing plate 6, the compression springs are fully compressed, and each column arm 52 can control the fixing rod 53 to radially move away from the axis of the connecting frame 5 with the sliding action of the shaft pin and the arc-shaped groove. At this time, the pin on the scraper 45 can be at the end of the arc segment of the guide groove 47 under the push of the fixing rod 53, and the limit spring 48 is in a stretched state. When the paint can is in the effect of vibrating the can, the limit spring 48 and the compression spring can make the fixing rod 53 freely adjust under the elastic force, so that the scraper 45 can flexibly contact the inner wall of the paint can.

[0022] In this embodiment, a plurality of sliding rods 61 are slidably connected in the upper shaft ring 42. The lower ends of the sliding rods 61 are connected to the shaft pressing plate 6. A fixed sleeve 62 is slidably sleeved on the main shaft 41, and the upper ends of the sliding rods 61 are fixed to the fixed sleeve 62. A hydraulic cavity 63 is fixed on the coupling frame 3. A piston is slidably connected in the hydraulic cavity 63. The main shaft 41 is connected through a pipe sleeve 64 in the middle of the hydraulic cavity 63. A driving rod 65 is vertically fixed below the piston. A sliding sleeve 66 is fixed below the driving rod 65, and the sliding sleeve 66 is in rotational contact with the fixed sleeve 62. Thus, when the main shaft 41 is rotating, the fixed sleeve 62 can rotate synchronously with the main shaft 41, and the sliding sleeve 66 drives the fixed sleeve 62 to perform vertical sliding adjustment through the rotational contact with the fixed sleeve 62. Among them, in the fine cleaning stage, the pin on the scraper 45 is in the straight segment of the guide groove 47 (if the contact strength between the scraper 45 and the inner wall of the paint can is not enough, the lower driver 14 can slide along the cross beam 12 to make the scraping mechanism 4 eccentric with the paint can, and the paint can can be controlled to rotate). At this time, the driving rod 65 can make the sliding sleeve 66 and the fixed sleeve 62 slide reciprocally dynamically under the up and down push of the piston. Each fixing rod 53 can control the pin on the scraper 45 to slide along the guide groove 47 to the inclined segment, and the angle of the scraper 45 is not more than 15°. Thus, it not only ensures the multi-angle scraping and cleaning operation of the scraper 45 in the fine cleaning process, but also can effectively change the contact pressure between the scraper and the tank wall, avoiding scraping damage caused by single overpressure contact. At the same time, the lower driver 14 can control the whole scraping mechanism 4 to perform small-amplitude up and down displacement, further improving the scraping effect. During this process, the flushing pipe can intermittently flush the tank wall.

[0023] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention should cover within the protection scope of the present invention according to the technical solution and inventive concept of the present invention by making equivalent replacements or changes.
