Technical Field

[0001] The utility model mainly relates to the technical field of powder coatings, in particular to a powder coating vibrating screen. Background Art

[0002] Powder coating is a solid powdered synthetic resin coating composed of solid resin, pigment, filler and additives. Unlike ordinary solvent-based coatings and water-based coatings, its dispersion medium is not solvent and water, but air. It has the characteristics of no solvent pollution, 100% film formation and low energy consumption. Powder coatings are divided into two categories: thermoplastic and thermosetting.

[0003] At present, powder coatings usually need to be filtered and screened during production to screen out some condensed block coatings for further processing. During screening, a filter is usually used for shaking filtration. When the block coatings are filtered out by the filter, it is usually necessary to pour the block coatings out of the filter. This operation is troublesome, labor-intensive, and has low material discharge efficiency. Utility Model Content

[0029] An opening is arranged at the top of the side of the sieve platform 10 on one side of the sieve mesh 20, and a baffle 40 is rotatably connected to the opening of the side of the sieve platform 10 via a damping shaft.

[0030] It should be noted that the motors of the device are electrically connected to the conventional controller, and the sliding block 53 slidably connected to the screw rod 52 has a built-in nut.

[0031] For details, please refer to the attached Figure 2 The inner walls of both sides of the sieve platform 10 are provided with movable grooves 12, and the two sides of the sieve 20 are provided with mesh frames 21, and the outer sides of the mesh frames 21 are rotatably connected with movable wheels 22, and the movable wheels 22 are located inside the movable grooves 12 at corresponding positions;

[0032] Furthermore, the outer surface of the movable wheel 22 is provided with an elastic rubber sleeve;

[0033] In this embodiment, it should be noted that the movable wheel 22 can be raised and lowered in the movable groove 12, so as to cooperate with the vibration mechanism 30 to realize vibration screening of the screen 20. At the same time, the elastic rubber sleeve outside the movable wheel 22 has a certain elasticity, which can ensure the smooth movement of the movable wheel 22 in the movable groove 12.

[0034] For details, please refer to the attached Figure 2 and attached Figure 5 The vibration mechanism 30 includes a second motor 31 installed on the outside of the screen platform 10, a connecting rod 33 installed on the output end of the second motor 31, and two cams 32 installed on the left and right sides of the connecting rod 33.
