Description
Technical Field
[0001] The utility model relates to the technical field of paint production, and particularly relates to a wear-resistant polyurethane topcoat particle dispersion device. Background Art
[0002] In the production and application process of polyurethane topcoat, the uniform dispersion of topcoat particles is crucial for its final performance and quality. Uneven particle dispersion may cause various problems after the topcoat is applied, such as rough surface, uneven color, etc. Therefore, in order to achieve the uniform dispersion of topcoat particles, special dispersion equipment is usually required. However, since most traditional polyurethane topcoat particle dispersion equipment uses fixed stirrers or dispersers, the height of the stirring disks inside these equipment is often fixed, and they can only effectively disperse the raw materials at a specific height inside the storage tank. For the raw materials at other heights inside the storage tank, the dispersion effect is greatly reduced. Therefore, we propose a wear-resistant polyurethane topcoat particle dispersion device to solve the above problems. Content of the Utility Model

For the raw materials at other heights inside the storage tank, the dispersion effect is greatly reduced.

[0023] As Figures 1 to 7As shown in the figure, an abrasive-resistant polyurethane topcoat particle dispersion device is proposed in an embodiment of the present utility model, which includes a support frame 1.

The rod body of the rotating shaft 401 is movably installed inside the internal tooth groove 407. A gear 406 is installed at the upper end of the rod body of the rotating shaft 401, and the gear 406 is meshed with the internal tooth groove 407. A stirring disc 421 is installed at the lower end of the rotating shaft 401, and the stirring disc 421 is installed inside the storage barrel 2. A motor 410 is installed at the rear end of the lower surface of the support frame 1. Driving discs 408 are respectively installed at the output end of the motor 410 and the outside of the rotating rod 402. A belt 409 is sleeved and installed between the driving discs 408. A connecting block 412 is sleeved and installed at the lower end of the rod body of the rotating shaft 401. A cylinder 411 is installed at the upper end of the support frame 1. The output end of the cylinder 411 is connected to the connecting block 412. A sealing cover 415 is clamped and installed at the upper end of the storage barrel 2. The rod body of the rotating shaft 401 is movably installed through the inside of the sealing cover 415. A positioning rod 420 is movably installed at the upper end of the sealing cover 415, and the positioning rod 420 is clamped and installed inside the rotating shaft 401.
[0024] As Figures 3 to 7 As shown in the figure, in another embodiment of the present utility model, a through hole 403 is provided through the upper end of the support frame 1. The rotating rod 402 is movably installed through the inside of the through hole 403. A limiting groove 405 is provided inside the through hole 403. A first limiting block 404 is installed on the outer side of the rod body of the rotating rod 402, and the first limiting block 404 is clamped and installed inside the limiting groove 405. A second limiting block 413 is fixedly installed on the outer side of the rod body of the rotating shaft 401 located inside the connecting block 412, and the second limiting block 413 is clamped and installed inside the connecting block 412. A sliding groove 416 is provided on the upper surface of the sealing cover 415. A sliding block 417 is movably installed inside the sliding groove 416. A positioning rod 420 is fixedly installed on the side of the sliding block 417 close to the rotating shaft 401. A positioning hole 414 is provided through the inside of the rod body of the rotating shaft 401, and the positioning rod 420 is clamped and installed inside the positioning hole 414. A handle 419 is installed on the side of the sliding block 417 away from the positioning rod 420. Guide rods 418 are respectively installed at both ends inside the sliding groove 416, and the rod bodies of the guide rods 418 are movably installed through the inside of the sliding block 417.
[0025] The user places the storage bucket 2 on the upper end of the clamping frame 3, and then the user pours the raw materials into the interior of the storage bucket 2. After the raw materials are poured, the air cylinder 411 drives the rotating shaft 401 to move downward through the connecting block 412 and the second limiting block 413, so that the rotating shaft 401 drives the gear 406 to slide along the internal tooth groove 407, and the rotating shaft 401 drives the sealing cover 415 and the stirring disc 421 to move. Then, when the stirring disc 421 moves into the interior of the storage bucket 2 and the sealing cover 415 is clamped and connected to the upper end of the storage bucket 2 at the same time, the user can pull the slider 417 and the positioning rod 420 through the handle 419, so that the positioning rod 420 disengages from the interior of the positioning hole 414. Then, the motor 410 drives the rotating rod 402 to rotate through the transmission disc 408 and the belt 409. Then, the rotating rod 402 drives the rotating shaft 401 and the stirring disc 421 to rotate through the internal tooth groove 407 and the gear 406, so that the stirring disc 421 stirs and disperses the raw materials. At the same time, the air cylinder 411 can drive the rotating shaft 401 and the stirring disc 421 to move up and down through the connecting block 412 and the second limiting block 413 to adjust the height of the stirring disc 421 inside the storage bucket 2, so that it evenly stirs and disperses each component inside the storage bucket 2. At the same time, when the rotating shaft 401 moves up and down, the rotating shaft 401 drives the gear 406 to move along the internal tooth groove 407, so that it neither hinders the movement of the rotating shaft 401, and at the same time the rotating rod 402 can still drive the rotating shaft 401 to rotate;
[0026] The first limiting block 404 and the limiting groove 405 are used to position the position of the rotating rod 402, so that the rotating rod 402 stably cooperates with the internal tooth groove 407 and the transmission disc 408 to drive the rotating shaft 401, and improve the stability performance during the rotation of the rotating shaft 401;
[0027] By clamping and installing the second limiting block 413 inside the connecting block 412, it is not only convenient for the air cylinder 411 to drive the rotating shaft 401 to move up and down through the connecting block 412 and the second limiting block 413, but also does not hinder the rotation of the rotating shaft 401, which is more convenient;
[0028] The guiding rod 418 is used to assist the slider 417 to move, so that the slider 417 stably drives the positioning rod 420 to insert into or disengage from the interior of the positioning hole 414. Thus, when the raw materials do not need to be processed or are processed, the positioning rod 420 is inserted into the interior of the positioning hole 414, which is convenient for the rotating shaft 401 to drive the sealing cover 415 to move up and down. At the same time, when the rotating shaft 401 needs to drive the stirring disc 421 to work, the positioning rod 420 disengages from the interior of the positioning hole 414, and then the sealing cover 415 is stably clamped on the upper end of the storage bucket 2 and does not move up and down with the rotating shaft 401, improving the sealing performance of the sealing cover 415 for the storage bucket 2 and avoiding the situation that the raw materials splash to the outside.
[0029] The working principle of this wear-resistant polyurethane topcoat particle dispersion device:
[0030] During use, first, the user places the storage bucket 2 on the upper end of the clamping frame 3, and then the user pours the raw materials into the interior of the storage bucket 2. After the raw materials are poured, the air cylinder 411 drives the rotating shaft 401 to move downward through the connecting block 412 and the second limiting block 413, enabling the rotating shaft 401 to drive the gear 406 to slide along the internal tooth groove 407, and the rotating shaft 401 to drive the sealing cover 415 and the stirring disc 421 to move. Then, when the stirring disc 421 moves into the interior of the storage bucket 2 and the sealing cover 415 is clamped and connected to the upper end of the storage bucket 2, the user can pull the slider 417 and the positioning rod 420 through the handle 419, causing the positioning rod 420 to disengage from the interior of the positioning hole 414. Then, the motor 410 drives the rotating rod 402 to rotate through the transmission disc 408 and the belt 409. Then, the rotating rod 402 drives the rotating shaft 401 and the stirring disc 421 to rotate through the internal tooth groove 407 and the gear 406, enabling the stirring disc 421 to stir and disperse the raw materials. At the same time, the air cylinder 411 can drive the rotating shaft 401 and the stirring disc 421 to move up and down through the connecting block 412 and the second limiting block 413 to adjust the height of the stirring disc 421 inside the storage bucket 2, so as to evenly stir and disperse each component inside the storage bucket 2. At the same time, when the rotating shaft 401 moves up and down, the rotating shaft 401 drives the gear 406 to move along the internal tooth groove 407, thus neither hindering the movement of the rotating shaft 401 nor preventing the rotating rod 402 from driving the rotating shaft 401 to rotate.
[0031] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, based on the above description, other different forms of changes or variations can be made. It is impossible to enumerate all the implementation manners here. Any obvious changes or variations derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
