The paint is continuously released when the discharge roller rotates. At this time, the rubber paste in the storage frame contacts with the surface of the paint and adheres to it. When the rubber paste on the front side of the storage frame is applied, the storage frame is rotated clockwise, and the storage frame drives the arc-shaped gear block to rotate clockwise. When the storage frame stops rotating, the meshing action between the arc-shaped gear block and the arc-shaped rack makes the arc-shaped gear block and the storage frame hover stably, thereby quickly changing the inclination angle of the storage frame, so that the rubber paste on the rear side of the storage frame flows forward, and the second motor is started.

The inner surface of the sliding sleeve shaft is slidably connected to the circumferential surface of the guide rod. The arcuate tooth block and the arcuate rack are meshed and connected. When the rubber paste adheres to the paint, it is generally necessary to manually spread it evenly with a brush. When the stirring plate reciprocates left and right, it drives the arcuate connecting plate to reciprocate left and right through the transmission card plate 1 and the transmission card plate 2. The arcuate connecting plate drives the arcuate smearing plate to reciprocate left and right through the sliding rod. The arcuate smearing plate contacts the rubber paste adhered to the paint to spread it evenly. When the thickness of the paint is different, the arcuate smearing plate approaches the arcuate connecting plate according to the thickness of the paint and the rubber paste smeared on the paint, and slides in the arcuate connecting plate through the sliding rod to maintain stability. When the arcuate connecting plate reciprocates left and right, it drives the sliding sleeve shaft to slide back and forth on the guide rod, so that the sliding rod and the arcuate smearing plate can move more smoothly when reciprocating.

[0007] The scraping roller is fixedly connected to the right end of the main shaft, the slide groove is opened on the upper surface of the connecting half roller, and the slide block is slidably connected to the inner surface of the slide groove.

When the worker requires, the excess rubber paste needs to be scraped off. The rotation of the main shaft drives the connecting half roller to rotate, and the connecting half roller drives the scraping roller to rotate through the slider. The tip of the scraping roller contacts the rubber paste and scrapes it off. The excess rubber paste accumulates in the groove of the scraping roller. The slider is slid in the slide groove, and the slider drives the scraping roller to move, thereby changing the distance between the tip of the scraping roller and the axis of the main shaft. When the sliding sleeve shaft reciprocates left and right, it drives the connecting plate to reciprocate left and right, and the connecting plate drives the scraping shaft to reciprocate left and right through the movable plate. When the scraping shaft moves, the rubber paste in the groove of the scraper roller is wiped off, and when the scraper roller rotates, it pushes the scraping shaft and the movable plate to rotate downward by a certain angle along the hinge between the movable plate and the connecting plate.

At this time, the rubber paste in the storage frame contacts and adheres to the surface of the coating; Step 3: After that, when the rubber paste on the front side of the storage frame is consumed, the rubber paste on the front side of the storage frame is continuously tilted to be applied, so that the rubber paste in the storage frame continuously flows to the rear side of the coating roller and adheres to the coating surface to prevent the coating from being interrupted; Step 4: Finally, the applied paint and rubber paste move from the gap between the coating roller and the scraper roller to the external drying device, which dries the rubber paste to solidify it on the paint, completing the processing.

[0009] The present invention adopts the above technical solution to bring the following beneficial effects: 1. The rubber paste transfer coating equipment has an arc-shaped tooth block that allows the storage frame to suspend stably, thereby quickly changing the inclination angle of the storage frame, allowing the rubber paste on the rear side of the storage frame to flow forward, preventing the coating from being interrupted, and eliminating the need for staff to manually push the rubber paste forward with tools, thereby improving the ease of use of the device. The stirring plate stirs the rubber paste in the storage frame to prevent the rubber paste from solidifying during heat dissipation, making it difficult to apply to the paint, thereby improving the coating efficiency. The left and right reciprocating movement of the stirring plate increases the stirring range and stirring effect, further preventing the rubber paste from solidifying.

[0010] 2. In the rubber paste transfer coating equipment, the arc-shaped coating plate contacts the rubber paste adhered to the paint and spreads it evenly, thereby improving the coating uniformity, and does not require manual operation, thereby improving the ease of use. The arc-shaped coating plate is close to the arc-shaped connecting plate according to the thickness of the paint and the rubber paste applied on the paint, so as to apply paints of different thicknesses, thereby improving the applicability of the device. The guide rod makes the arc-shaped coating plate more stable when reciprocating, thereby enabling the arc-shaped coating plate to smoothly spread the rubber paste on the paint, thereby further improving the coating uniformity.

[0011] 3. In the rubber paste transfer coating equipment, the tip of the scraper roller scrapes off the rubber paste after contacting it, and the excess rubber paste accumulates in the groove of the scraper roller, which better meets the processing requirements. By changing the distance between the tip of the scraper roller and the axis of the main shaft, the scraping range of the scraper roller is changed, which further adapts to the processing requirements and improves the applicability of the device. When the scraper shaft moves, the rubber paste in the groove of the scraper roller is wiped off to prevent the groove of the scraper roller from being filled with rubber paste, thereby preventing the rubber paste on the coating from being continuously scraped off, thereby improving the scraping effect.

[0016] Working principle: one end of the paint is wound around the circumference of the supporting roller 4 and the smear roller 5 and passes it forward from the gap between the smear roller 5 and the scraper roller 94, and the first motor is started. The first motor drives the discharge roller 3 to rotate clockwise. The discharge roller 3 continuously discharges the paint when it rotates. At this time, the rubber paste in the storage frame 7 contacts with the surface of the paint and adheres to it. When the rubber paste on the front side of the storage frame 7 is applied, the storage frame 7 is rotated clockwise, and the storage frame 7 drives the arc-shaped tooth block 71 to rotate clockwise. When the rotation of the storage frame 7 is stopped, the meshing action between the arc-shaped tooth block 71 and the arc-shaped rack 72 makes the arc-shaped tooth block 71 and the storage frame 7 hover stably, thereby quickly changing the inclination angle of the storage frame 7, so that the rubber paste on the rear side of the storage frame 7 flows forward, preventing the interruption of the application, and there is no need for the staff to manually push the rubber paste forward with tools, which improves the convenience of use of the device.

Because the arc through groove 73 is opened, the rotation cannot limit the rotation of the storage frame 7.

[0017] See also Figure 1-Figure 9On the basis of the above embodiment, in another embodiment of the present invention, the paint spreading device 8 includes an arc-shaped connecting plate 81, an arc-shaped smearing plate 82, and a sliding rod 83. The arc-shaped connecting plate 81 is arranged on the rear side of the smearing roller 5, and the sliding rod 83 is slidably connected to the inner surface of the arc-shaped connecting plate 81. The arc-shaped smearing plate 82 is fixedly connected to the end of the sliding rod 83 close to the smearing roller 5. The arc-shaped smearing plate 82 contacts the rubber paste adhered to the paint to spread it evenly, thereby improving the coating uniformity, and no manual operation is required, thereby improving the convenience of use. The paint spreading device 8 also includes a transmission card plate 1 84, a transmission card plate 2 85, a guide rod 86, and a sliding sleeve shaft 87.

[0018] Working principle: When the rubber paste adheres to the paint, it is generally necessary to manually spread it evenly with a brush. When the stirring plate 79 moves back and forth, the transmission card plate 1 84 and the transmission card plate 2 85 drive the arc-shaped connecting plate 81 to move back and forth.

[0019] See also Figure 1-Figure 9 On the basis of the above embodiment, in another embodiment of the present invention, the scraping device 9 includes a connecting half roller 91, a slide groove 92, and a slider 93.

The excess rubber paste accumulates in the groove of the scraping roller 94, which better meets the processing requirements. The distance between the tip of the scraping roller 94 and the axis of the main shaft 6 is changed, thereby changing the scraping range of the scraping roller 94, further adapting to the processing requirements and improving the applicability of the device. The scraping device 9 also includes a scraping roller 94, a connecting plate 95, a movable plate 96, The scraping shaft 97 and the scraping roller 94 are fixedly connected to the side of the slider 93 away from the slide groove 92, the connecting plate 95 is fixedly connected to the upper surface of the sliding sleeve shaft 87, the movable plate 96 is hinged at the top of the connecting plate 95, the scraping shaft 97 is fixedly connected to the front end of the movable plate 96, the connecting half roller 91 and the left side of the second fixed plate 2 are rotatably connected, the lower surface of the scraping roller 94 and the upper surface of the connecting half roller 91 are in contact with each other, the scraping shaft 97 and the inner surface of the scraping roller 94 are in contact with each other, and a torsion spring is provided at the hinge of the movable plate 96 and the connecting plate 95. When the scraping shaft 97 moves, the rubber paste in the groove of the scraping roller 94 is wiped off to prevent the groove of the scraping roller 94 from being filled with the rubber paste, thereby preventing the rubber paste on the coating from being continuously scraped off, thereby improving the scraping effect.

[0020] Working principle: when the rubber paste applied on the coating is too much and too thick and does not meet the processing requirements, the excess rubber paste needs to be scraped off, the main shaft 6 rotates to drive the connecting half roller 91 to rotate, and the connecting half roller 91 drives the scraping roller 94 to rotate through the slider 93, and the tip of the scraping roller 94 contacts the rubber paste and scrapes it off, and the excess rubber paste accumulates in the groove of the scraping roller 94, which better meets the processing requirements, and the slider 93 is slid in the slide groove 92, and the slider 93 drives the scraping roller 94 to move, thereby changing the distance between the tip of the scraping roller 94 and the axis of the main shaft 6, thereby changing the scraping range of the scraping roller 94, further adapting to the processing requirements, and improving the applicability of the device, When the movable sleeve shaft 87 reciprocates left and right, it drives the connecting plate 95 to reciprocate left and right. The connecting plate 95 then drives the scraper shaft 97 to reciprocate left and right through the movable plate 96. When the scraper shaft 97 moves, the rubber paste in the groove of the scraper roller 94 is wiped off to prevent the groove of the scraper roller 94 from being filled with rubber paste and thus being unable to continuously scrape the rubber paste on the paint, thereby improving the scraping effect. When the scraper roller 94 rotates, it pushes the scraper shaft 97 and the movable plate 96 to rotate downward by a certain angle along the hinge between the movable plate 96 and the connecting plate 95. When the groove of the scraper roller 94 is aligned with the scraper shaft 97 again, the elastic reset action of the torsion spring drives the movable plate 96 and the scraper shaft 97 to reset elastically.
