[0002] Rubber asphalt waterproof coating is a high-performance waterproof material, which is mainly made by polymer synthesis technology. The adhesive material in its film-forming substance is mainly composed of asphalt and rubber, including recycled rubber or synthetic rubber.

[0003] Existing conveying devices for the production of spray rubber asphalt waterproof coatings, such as the Chinese utility model patent with publication number CN216679426U, entitled a conveying device for the production of spray rubber asphalt waterproof coatings, require manual pushing of the card block along the top of the storage tank to move one circle to complete the cleaning of the residual paint. In reality, the storage tank is large in size and the top is far from the bottom. It is unclear how to drive the card block to move stably with cleaning plates 1 and 2, and the simple plate-like structure cannot guarantee the cleaning effect of the paint with high viscosity. After cleaning plates 1 and 2 move one circle along the storage tank, there will still be paint remaining on cleaning plates 1 and 2 that cannot be cleaned. Therefore, it is necessary to design a conveying device for the production of spray rubber asphalt waterproof coatings to address the above problems. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides a technical solution: a conveying device for spraying rubber asphalt waterproof coating production, including a storage tank 1, a conveying pipe 2, a paint pump 3, a support plate 4, a servo motor 5, a driving gear 6, a driven gear 7, a vertical sleeve 8, a vertical threaded rod 9, a blocking plate 10, a scraper ring 11, a sealing gasket 12, a high-pressure water supply pipe 13 and a high-pressure nozzle 14. The conveying pipe 2 is installed at the bottom of the storage tank 1, and the paint pump 3 is installed on the conveying pipe 2. The top of the storage tank 1 is fixed with a support plate 4, and the top end of the support plate 4 is fixedly installed with a servo motor 5. A driving gear 6 is fixed to the end of the output shaft of the servo motor 5, and the driving gear 6 is meshed with the driven gear 7. The driven gear 7 is fixedly installed on the top of the outer wall of the vertical sleeve 8. The vertical sleeve 8 is installed on the other end of the top of the support plate 4 through the bearing seat in the middle of the outer wall. The inner wall of the vertical sleeve 8 is connected to the vertical threaded rod 9, and a blocking plate 10 is fixed to the top of the vertical threaded rod 9. The bottom end of the vertical threaded rod 9 is connected and fixed to the top surface of the scraper ring 11. A sealing gasket 12 is inlaid and fixed on the outer wall of the scraper ring 11, and a high-pressure water supply pipe 13 is fixedly installed on the vertical part of the inner wall of the scraper ring 11.

[0021] In this example, the support plate 4, servo motor 5, driving gear 6, driven gear 7, vertical sleeve 8 and vertical threaded rod 9 are all symmetrically distributed about the center of the scraper ring 11. The driving gear 6 and the driven gear 7 are both bevel gears. The diameter of the driving gear 6 is smaller than the diameter of the driven gear 7. The above structural design enables the servo motor 5 to stably drive the vertical threaded rod 9 to move vertically with the scraper ring 11 through the driving gear 6, the driven gear 7 and the vertical sleeve 8.

[0022] The vertical sleeve 8 is threadedly connected to the vertical threaded rod 9. The overall length of the vertical threaded rod 9 is greater than the height of the vertical part of the inner wall of the storage tank 1. The above-mentioned structural design enables the vertical sleeve 8 to utilize the threaded connection relationship to drive the vertical threaded rod 9 to move a sufficient distance downward in the storage tank 1 with the scraper ring 11 when rotating, thereby ensuring the cleaning effect of the residual paint.

[0023] The outer diameter of the scraper ring 11 is equal to the inner diameter of the storage tank 1 , and the cross-sectional shape of the scraper ring 11 when viewed from the front is a right-angled trapezoid. The above structural design enables the scraper ring 11 to fit tightly against the inner wall of the storage tank 1 and scrape off the residual paint on the inner wall of the storage tank 1 from top to bottom.

[0024] The top view shape of the high-pressure water supply pipe 13 is annular, and a high-pressure nozzle 14 is installed at the bottom of the high-pressure water supply pipe 13. The above structural design can use water flow to wash the remaining paint and the scraped paint to avoid paint residue.

[0025] The high-pressure nozzles 14 are densely distributed at equal angles about the center of the high-pressure water supply pipe 13. The high-pressure nozzles 14 are inclined toward the inner wall of the storage tank 1. The above-mentioned structural design ensures that the high-speed water flow can fully flush the residual paint on the inner wall of the storage tank 1, and cooperate with the scraper ring 11 to achieve a thorough cleaning effect.

[0026] Working principle: When the paint in the storage tank 1 is discharged through the delivery pipe 2, the symmetrically distributed servo motor 5 drives the driving gear 6 to rotate forward at the same speed, and the driving gear 6 drives the driven gear 7 to rotate stably with the vertical sleeve 8. The vertical sleeve 8 drives the vertical threaded rod 9 to move the scraper ring 11 vertically downward by using the threaded connection relationship. The outer wall of the scraper ring 11 and the outer side surface of the sealing gasket 12 are stably fitted with the inner wall of the storage tank 1;

[0027] At the same time, the high-pressure water supply pipe 13 is supplied with water through an external high-pressure water pump connected to the high-pressure water supply pipe 13, and the water flow is sprayed out from the high-pressure nozzle 14 at a high speed to wash the paint remaining on the inner wall of the storage tank 1. Then the scraper ring 11 moves downward, and the paint remaining on the inner wall of the storage tank 1 is scraped downward by the sharp part at the bottom. The high-speed water flow sprayed by the high-pressure nozzle 14 also washes the paint adhered to the inner bottom inclined surface of the scraper ring 11 to prevent the paint from remaining on the inner bottom inclined surface of the scraper ring 11 and affecting the cleaning effect. The scraped paint flows downward with the water flow and is discharged through the delivery pipe 2;

[0028] When the scraper ring 11 moves to the bottom of the inner side of the storage tank 1, the servo motor 5 is controlled to drive the driving gear 6 to rotate in the same reverse speed. The driving gear 6 drives the driven gear 7 to rotate stably in the reverse direction with the vertical sleeve 8. The vertical sleeve 8 drives the vertical threaded rod 9 to move the scraper ring 11 vertically upward and reset to disengage from the storage tank 1. The storage tank 1 can then start production operation again. This is the working principle of the conveying device for the production of spray rubber asphalt waterproof coating.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
