Description

Technical Field

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

[0002] Currently, existing paint scraping devices (such as patent publication number: CN221361761U) disclose a paint scraping device for paint production. The centrifugal force generated by the rotation of the stirring shaft causes the telescopic plate on the telescopic scraper to pop out. The end face of the telescopic plate contacts the inner wall of the mixing tank, causing the paint adhering to the inner wall of the mixing tank to be scraped off and fall into the mixing tank. A pressure sensor installed at the end of the telescopic plate can be set to reflect the pressure generated by the telescopic plate on the inner wall of the mixing tank in a timely manner.

[0003] In the aforementioned patent, the scraper is a long strip structure that cannot be deformed or bent. On surfaces with protrusions or dents, the scraper will be lifted up by the protrusions. During the scraping process, the force is concentrated at the local contact point. The scraper can only adhere to the surface in a local straight area and cannot make contact at the dents, resulting in residual paint. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a paint scraping device for paint production, which solves the technical problems that the scraper is a long strip structure that cannot be deformed or bent. When there are raised or dented surfaces, the scraper will be lifted up by the raised parts, and the force is concentrated at a local contact point during the scraping process, so the scraper can only adhere to a local straight area.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A paint scraping device for paint production includes a tank and a fixed cylinder, wherein two guide rails are fixedly mounted on the surface of the fixed cylinder; Each guide rail plate has two push plates slidably installed inside. Each push plate has a diagonal brace rotatably installed at its side end. Each diagonal brace has a pivot seat rotatably installed at its end. The ends of the two pivot seats are equipped with the same flexible scraper. An elastic rod is fixedly installed inside the flexible scraper.

[0006] Preferably, each of the guide rail plates has a control block slidably installed inside, and each of the two sides of the control block has an electric push rod fixedly installed. Each of the diagonal braces is fixedly mounted with a mounting box at one end, and a nozzle is fixedly mounted at the end of each mounting box.

[0007] Preferably, a hollow tube is fixedly installed at the top of each of the mounting boxes, and the end of each hollow tube is connected to a push plate; A rotating shaft is rotatably mounted on the top end of the fixed cylinder, a collar is rotatably mounted on the surface of the rotating shaft, and two pre-tightening rods are fixedly mounted on the surface of the collar. The top of the collar has an interface, and the inside of the collar is hollow.

[0008] Compared with the prior art, the present invention has the following beneficial effects; In this invention, by synchronously sliding the push plate and the control block, the push plate and the control block simultaneously press the top of the inclined support rod, causing the inclined support rod to tilt and its end to partially press the side end of the flexible scraper. At the same time, by adjusting the deflection angle of the inclined support rod at different positions, combined with the flexibility of the flexible scraper itself, the flexible scraper can conform to different curved surfaces of the tank, ensuring that the coating on different parts of the inner wall of the tank can be scraped off.

[0009] In this invention, the push plate presses the top of the diagonal brace, causing the diagonal brace to deflect at the end of the flexible scraper. At the same time, the mounting box is adjusted to change the angle, and cleaning fluid is sprayed into the tank through the nozzle. The spray angle of the nozzle can be precisely adjusted according to the scraping situation to target the residual paint inside the tank. Combined with the rotating flexible scraper, scraping and cleaning are carried out in a coordinated manner, improving cleaning efficiency and effectiveness. Attached Figure Description

[0013] This application provides a paint scraping device for paint production, which effectively solves the problem that the scraper is a long strip structure that cannot be deformed or bent. On surfaces with protrusions / dents, the scraper will be lifted by the protrusions, and the force will be concentrated at a local contact point during the scraping process, so the scraper can only adhere to a local straight area. By synchronously sliding the push plate and the control block, the push plate and the control block simultaneously squeeze the top of the inclined support rod. The inclined support rod is tilted, and its end squeezes the side end of the flexible scraper in sections. At the same time, by adjusting the deflection angle of the inclined support rod at different positions, combined with the flexibility of the flexible scraper itself, the flexible scraper can be made to conform to different curved surfaces of the tank, ensuring that paint on different parts of the inner wall of the tank can be scraped off. Example

[0014] like Figure 1 - Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem that the scraper is a long strip structure that cannot be deformed or bent. For surfaces with protrusions / dents, the scraper will be lifted by the protrusions, and the force will be concentrated at a local contact point during scraping, so the scraper can only adhere to a local straight area. The overall idea is as follows: To address the problems existing in the prior art, this utility model provides a paint scraping device for paint production, including a tank 11 and a fixed cylinder 16. Two guide rail plates 17 are fixedly installed on the surface of the fixed cylinder 16, and the two guide rail plates 17 are symmetrically distributed on the outer side of the fixed cylinder 16. Two push plates 22 are slidably installed inside each guide plate 17. Each push plate 22 has a diagonal brace 15 rotatably installed on its side end. Each diagonal brace 15 has a pivot seat 14 rotatably installed at its end. The same flexible scraper 12 is installed at the end of the two pivot seats 14. An elastic rod 13 is fixedly installed inside the flexible scraper 12. Through the synchronous sliding of the push plate 22 and the control block 24, the push plate 22 and the control block 24 simultaneously press the top of the diagonal brace 15. Through the inclination of the diagonal brace 15, the end of the diagonal brace 15 respectively presses the side end of the flexible scraper 12 in sections, so that the flexible scraper 12 fits the inner side of the tank body 11. By adjusting the deflection angle of the diagonal brace 15 at different positions, and the fact that the flexible scraper 12 itself is flexible, it can fit different curved surfaces. In addition, a bevel gear ring is installed at the top of the flexible scraper 12. With the help of the motor and the transmission rod, the fixed cylinder 16 drives the flexible scraper 12 to rotate continuously inside the tank body 11. Each guide rail plate 17 has a control block 24 slidably installed inside. Each control block 24 has an electric push rod 23 fixedly installed on both sides. The control block 24 drives the electric push rod 23 to extend and retract. The extension and retraction of the two sets of electric push rods 23 can pull the control block 24 and the push plate 22 at the end of the guide rail plate 17, allowing the push plate 22 and the control block 24 to slide inside the guide rail plate 17 again, adjusting the deflection angle of the diagonal brace 15 and the curvature of the end of the flexible scraper 12. Each diagonal brace 15 is fixedly mounted with a mounting box 25 at its side end, and a nozzle 26 is fixedly mounted at the end of each mounting box 25. The push plate 22 presses the top of the diagonal brace 15, causing the diagonal brace 15 to deflect at the side end of the flexible scraper 12. At the same time, the mounting box 25 is adjusted to change the angle, and the cleaning fluid is sprayed into the inside of the tank 11 through the nozzle 26. In conjunction with the rotating flexible scraper 12, the residual images inside the tank 11 are cleaned. A hollow tube 27 is fixedly installed at the top of each mounting box 25. The end of each hollow tube 27 is connected to the push plate 22. The end of the hollow tube 27 has a bifurcated structure to deliver the cleaning fluid to the nozzle 26. A rotating shaft 18 is rotatably mounted on the top of the fixed cylinder 16. A collar 19 is rotatably mounted on the surface of the rotating shaft 18. Two pre-tightening rods 21 are fixedly mounted on the surface of the collar 19. By rotating the rotating shaft 18 in the forward direction, the end of the rotating shaft 18 rotates at the top of the fixed cylinder 16. The rotating shaft 18 also rotates freely inside the collar 19. The rotating shaft 18 drives the collar 19 to move downward. The pre-tightening rods 21 push the two push plates 22 to slide, so that the push plates 22 and the control block 24 slide downward inside the guide plate 17. The inclination of the diagonal brace 15 supports the flexible scraper 12 and controls the flexible scraper 12 to adhere and fix to the inner wall of the tank body 11 before it. The top of the collar 19 is provided with an interface. The inside of the collar 19 is hollow. The cleaning fluid is introduced into the inside of the collar 19 through the interface at the top of the collar 19. The cleaning fluid flows inside the collar 19. The pre-tightening rod 21 is equipped with a pipe connected to the push plate 22. The cleaning fluid is diverted to the hollow tube 27 through the cooperation of the pre-tightening rod 21 and the push plate 22. The cleaning fluid is sprayed onto the inner wall of the tank 11 through the nozzle 26. The flexible scraper 12 is used to quickly scrape off the coating on the inner wall of the tank 11.

[0015] Working principle: The first step is to rotate the rotating shaft 18 in the forward direction. The end of the rotating shaft 18 rotates at the top of the fixed cylinder 16 and rotates freely inside the collar 19, causing the collar 19 to move downward. The collar 19 pushes the two push plates 22 through the pre-tightening rod 21 to slide downward inside the guide plate 17. The push plates 22 press the top of the inclined support rod 15, causing the inclined support rod 15 to tilt. The end of the inclined support rod 15 presses the side end of the flexible scraper 12 in sections. Under the action of the elastic rod 13, the flexible scraper 12 adheres to the inner side of the tank body 11.

[0016] The control block 24 drives the electric push rod 23 to extend and retract. The two sets of electric push rods 23 extend and retract, pulling the control block 24 and the push plate 22 at the end of the guide plate 17 to slide inside the guide plate 17. By adjusting the deflection angle of the diagonal brace 15 at different positions, combined with the flexibility of the flexible scraper 12 itself, it can conform to different curved surfaces of the tank body 11.

[0017] In the second step, the bevel gear ring installed at the top of the flexible scraper 12, in conjunction with the motor and transmission rod, causes the fixed cylinder 16 to drive the flexible scraper 12 to rotate continuously inside the tank 11, scraping away the coating on the inner wall of the tank 11. Simultaneously, the push plate 22 presses the top of the diagonal support rod 15, causing the diagonal support rod 15 to deflect at the side end of the flexible scraper 12. The mounting box 25 is adjusted to change the angle, and cleaning fluid is sprayed into the inner side of the tank 11 through the nozzle 26. The cleaning fluid is introduced into the collar 19 through the interface at the top of the collar 19. Inside tank 9, the pre-tightening rod 21 and push plate 22 work together to divert the paint to the hollow tube 27, and then spray it out through nozzle 26. With the help of the rotating flexible scraper 12, the paint residue inside the tank 11 is cleaned. The shaft 18 is rotated in the opposite direction, which drives the collar 19 to move upward. The pre-tightening rod 21 no longer pushes the push plate 22. The electric push rod 23 drives the control block 24 and push plate 22 to reset. The diagonal support rod 15 returns to its original position. The flexible scraper 12 separates from the inner wall of the tank 11, completing one scraping and cleaning operation.

[0018] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
