DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] In order to more clearly illustrate the technical solutions of the present utility model, the present utility model will be further described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only one embodiment of the present utility model. For those of ordinary skill in the art, without creative efforts, other embodiments obtained based on this drawing and embodiment all fall within the protection scope of the present utility model.

[0018] According to Figures 1-4As shown in the figure, a dust-proof crushing device for the production of environment-friendly powder coatings includes a conveying frame 1. At the end of the conveying section on the conveying frame 1, there is a crushing roller 2. A dust-proof cover 3 is covered on the outer periphery of the crushing roller 2. A cleaning assembly for cleaning the crushing roller 2 is provided on the dust-proof cover 3. The cleaning assembly includes a cleaning brush 4, and the cleaning brush 4 rotates to clean the dust on the two crushing rollers 2.

[0019] In the above specific implementation manner, by setting the dust-proof cover 3, a large amount of dust is prevented from being dispersed in the air during the crushing process. After the material is crushed, the cleaning brush 4 is used to clean the residual dust on the crushing roller 2, preventing a large amount of dust from being inhaled by the staff when manually cleaning the crushing roller 2, which affects physical health.

[0020] The cleaning brush 4 is installed on a bracket 5. A driving motor 6 is also installed on the bracket 5. The output end of the driving motor 6 is connected to the rotating shaft of the crushing roller 2. The cleaning brush 4 is located near the tangents of the rotations of the two crushing rollers 2. When the driving motor 6 is started, it drives the cleaning brush 4 to rotate. Preferably, the linear velocity of the rotation of the cleaning brush 4 is greater than the linear velocity of the rotation of the crushing roller 2. The cleaning brush 4 is located near the tangents of the rotations of the two crushing rollers 2. The staff needs to adjust the distance between the cleaning brush 4 and the two crushing rollers 2 during the work process to ensure that the cleaning brush 4 can clean the dust on the crushing roller 2 while the bristles will not be brought into the space between the two crushing rollers 2.

[0021] One end of the bracket 5 away from the cleaning brush 4 is connected to an electric telescopic rod 7, and the electric telescopic rod 7 is installed on the dust-proof cover 3. When the cleaning is completed and the crushing roller 2 needs to perform the crushing work, the electric telescopic rod 7 drives the cleaning brush 4 to move away from the crushing roller 2.

[0022] An inclined slide rail 8 is provided on the inner side wall of the dust-proof cover 3. A slider slidably connected to the slide rail 8 is provided on the bracket 5. The slide rail 8 plays a guiding role and at the same time supports the bracket 5.

[0023] An end cover 10 is provided on the top of the dust-proof cover 3, and an observation window 11 is provided at the front end of the dust-proof cover 3, which is convenient for observing the material feeding situation in the dust-proof cover 3 and the cleaning situation of the crushing roller 2. The end cover 10 is bolted to the dust-proof cover 3, which is convenient for the staff to open the end cover 10 to repair the inside of the dust-proof cover 3.

[0024] A moving trolley 12 for collecting materials is provided at the bottom of the dust-proof cover 3. Universal wheels 13 are provided at the bottom of the moving trolley 12.
