Description

Technical Field

[0001] This utility model relates to the field of coating technology, specifically a coating screening machine. Background Technology

[0002] Powder coatings are solid powdered synthetic resin coatings composed of solid resin, pigments, fillers, and additives. During the coating processing, a sieving machine is required to sieve the coating.

[0003] Currently, a Chinese patent discloses a sieving device for powder coatings, with publication number CN221674909U. In the disclosed technical solution, the drive motor, connecting rod, clapper, and protrusion work together to improve the efficiency of the filter screen when sieving powder coatings. By starting the drive motor, the connecting rod is rotated, and the clapper and protrusion can beat the filter screen, causing the filter screen to vibrate and improve the sieving efficiency.

[0004] Based on the aforementioned disclosed technical solutions and existing technologies, during the current coating screening process, the screened coating tends to accumulate, requiring a longer screening time to achieve sufficient separation and thus affecting the efficiency of coating screening. Therefore, we propose a coating screening machine to improve the efficiency of coating screening. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] This utility model provides, for example Figure 1-3 The coating screening machine shown includes a screening box 1. A collection frame 15 is provided at the bottom of the inner side of the screening box 1. A switch door 16 is installed on the lower side of the front of the screening box 1. Rollers are installed at the bottom of the collection frame 15. After opening the switch door 16, the collection frame 15 can be pulled out. An inclined screening plate 2 is installed inside the screening box 1. The bottom of the inner wall of the discharge port 3 is connected to the bottom of the screening plate 2 through a support spring 17. A discharge port 3 is opened on the right side of the screening box 1 for the screening plate 2 to pass through. In order to prevent the screened coating from falling on the support spring 17 and to ensure that the screened coating falls completely into the collection frame 15, the selected screening plate 2 can have the screening holes set on the left side of the screening plate 2. The right side of the screening plate 2 is a smooth plate, which facilitates the sliding of unqualified coating and also prevents the screened coating from falling on the support spring 17.

[0023] The coating material falls through the feeding cylinder 4. The bottom of the feeding cylinder 4 is connected to the left side of the top of the screening box 1. The inner side of the feeding cylinder 4 is rotatably connected to the rotating shaft 5. The outer side of the rotating shaft 5 is fixedly connected to the baffles 6 at equal intervals. One end of the baffle 6 abuts against the inner wall of the feeding cylinder 4. When the rotating shaft 5 rotates, the coating material can be stored between two adjacent baffles 6. When the two adjacent baffles 6 rotate downwards, the coating material falls.

[0024] The bottom of the feed hopper 7 is connected to the top of the feeding cylinder 4. Inside the feed hopper 7, there are two parallel augers 8. One end of the shaft between the two augers 8 passes through the feed hopper 7 and is connected to a gear 9. The two gears 9 mesh with each other. When the two augers 8 rotate, they can disperse the paint in the feed hopper 7, so that the paint falling between the two adjacent baffles 6 can be evenly distributed.

[0025] A rotating drive shaft 10 is rotatably connected inside the screening box 1 and located at the bottom of the screening plate 2. Cams 11 are sleeved on both sides of the outside of the drive shaft 10. The left side of the screening plate 2 is rotatably connected to the left side of the inner wall of the screening box 1. The bottom of the screening plate 2 abuts against the cams 11. When the cams 11 rotate, they cause the screening plate 2 to vibrate. While screening the coating, the unqualified coating is discharged from the discharge port 3. One end of the drive shaft 10 passes through the screening box 1 and is connected to a motor 12. A mounting bracket for the motor 12 is fixedly connected to the back of the screening box 1. One end of the drive shaft 10 is connected to the rotating shaft 5 through a transmission chain 13. Both the drive shaft 10 and the rotating shaft 5 are connected to a sprocket for transmission by the transmission chain 13. One end of the rotating shaft 5 is connected to one end of the intermediate shaft of one of the augers 8 through a transmission belt 14. One end of the rotating shaft 14 and one end of the intermediate shaft of one of the augers 8 are connected to a pulley for transmission by the transmission belt 14.

[0026] When it is necessary to adjust the efficiency of paint feeding, a sprocket with a larger ratio can be replaced on the rotating shaft 5 so that the rotation of the drive shaft 10 can slow down the rotation rate of the rotating shaft 5.

[0027] The implementation principle of a paint screening machine in this application embodiment is as follows: the paint to be screened is poured into the feed hopper 7, the motor 12 is started, the motor 12 drives the cam 11 to rotate through the drive shaft 10, thereby causing the screening plate 2 to vibrate and screen. The drive shaft 10 drives the rotating shaft 5 to rotate through the transmission chain 13, so that the paint in the feed hopper 7 can fall between two adjacent baffles 6. As the baffles 6 rotate, the paint falls to the left side of the top of the screening plate 2. When the paint falls from the feed hopper 7 into the feeding cylinder 4, the transmission belt 14 on the rotating shaft 5 drives the auger 8 to rotate. The two augers 8 cause the paint in the feed hopper 7 to move left and right, so as to disperse it.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
