Description

Technical Field

[0001] This utility model relates to the field of anti-clogging technology for paint hoppers, specifically an anti-clogging device for powder paint hoppers. Background Technology

[0002] When using a hopper to feed powder coatings, the hopper has a large top opening and a small bottom outlet. This causes the powder coating to be discharged at a lower rate than it is fed in when a large amount of powder coating is poured in. As a result, some powder coating accumulates inside the hopper and is squeezed against the inner wall. Under the pressure of this compression, the powder particles are bonded together, causing the powder coating to form lumps. These lumps can easily clog the outlet of the hopper.

[0003] Existing powder coating hopper anti-clogging devices have poor screening effects on powder coatings, affecting their quality. Furthermore, when powder coatings are discharged from the hopper, some powder coatings adhere to the inner wall of the hopper, hindering discharge. The present invention provides a powder coating hopper anti-clogging device that solves these problems. Utility Model Content

A stirring plate 13 is installed on the outer surface of the stirring rod 12. A disc 14 is installed at the other end of the dual-shaft motor 5. A positioning slider 15 is installed on the top of the disc 14. A strip plate 16 is installed at the bottom of the frame screen 2. A rectangular groove is opened inside the strip plate 16. A rectangular slider 17 is set inside the rectangular groove. A horizontal plate 18 is installed at one end of the rectangular slider 17. A connecting rod 19 is installed at the front and back of the horizontal plate 18. A push plate 20 is installed at the end of the connecting rod 19.

[0017] Specifically, the cooperation between the annular slider 10 and the annular groove guides the movement of the internal gear ring 9 and the scraper 11, improving the stability of their rotation.

[0018] Please see Figures 2 to 5 The annular block 4 has an annular groove inside that matches the annular slider 10. The end of the annular slider 10 is located inside the annular groove. The funnel body 1, the annular block 4, the annular slider 10 and the internal toothed ring 9 all have the same center.

[0019] Specifically, the transmission chain is designed to facilitate the synchronous rotation between the two transmission wheels 7, which in turn facilitates the rotation of the internal gear ring 9.

[0020] Please see Figures 4 to 5 There are two drive wheels 7, which are connected by a drive chain.

[0021] Specifically, the frame screen 2 is designed to facilitate the screening of powder coatings, making it easier to separate larger powder coatings and improve the quality of the powder coatings.

[0022] Please see Figures 1 to 6 The frame screen 2 is positioned higher than the funnel body 1, and the end of the frame screen 2 is located inside the funnel body 1. A U-shaped support plate 21 is installed on one side of the frame screen 2, and the other end of the U-shaped support plate 21 is fixedly connected to the funnel body 1.

[0023] Specifically, the cooperation between the positioning slider 15 and the positioning groove facilitates the movement of the horizontal plate 18 and the push plate 20, allowing the push plate 20 to move inside the frame screen 2, and causing the push plate 20 to push and collide with the powder coating inside the frame screen 2, thus facilitating the crushing effect on larger powder coatings.

The push plate 20 moves back and forth inside the frame screen 2, facilitating the pushing of the powder coating. Larger powder coatings are broken down into smaller ones, improving the quality of the powder coating. A dual-axis motor 5 drives one of the transmission wheels 7 to rotate. The two transmission wheels 7 are connected by a transmission chain, so that the two transmission wheels 7 rotate synchronously. This causes the other transmission wheel 7 to drive the round rod 6 and the gear 8 to rotate. The gear 8 meshes with the internal gear ring 9. The annular slider 10 moves guided inside the annular groove, causing the internal gear ring 9 to drive the annular slider 10 and the scraper 11 to rotate. The scraper 11 abuts against the inner wall of the funnel body 1, which facilitates the scraper 11 to clean the powder coating adhering to the inner wall of the funnel body 1. The stirring rod 12 and the stirring plate 13 rotate with the rotation of the scraper 11, which facilitates the stirring of the powder coating, prevents the powder coating from becoming lumpy, and improves the quality of the powder coating.
