Detailed Description of the Preferred Embodiments

[0022] Next, with reference to the drawings, through the description of the embodiments, the specific embodiments of the present invention will be further described in detail. The purpose is to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0023] Please refer to Figures 1-3, A powder coating crushing roller protection device, including a housing 1, a crushing roller 2 and a squeezing roller 3 arranged inside the housing 1. A slider 4 located inside the housing 1 is provided at the end of the crushing roller 2. A protection device 5 is arranged between the slider 4 and the housing 1, and a pressing spring 6 is arranged between the slider 4 and the housing 1.

[0024] During crushing, the crushing roller 2 and the squeezing roller 3 are pushed together by the pressing spring 6, so as to squeeze and crush the powder coating between the crushing roller 2 and the squeezing roller 3. When the crushing device is not in use, by using the protection device 5, the crushing roller 2 can be lifted to prevent the crushing roller 2 from being continuously squeezed with the squeezing roller 3 under the action of the pressing spring 6, which can effectively extend the service life of the crushing roller 2 and the squeezing roller 3.

[0025] The protection device 5 includes a protection insert plate 51 located between the housing 1 and the slider 4; the slider 4 and the crushing roller 2 are lifted by the protection insert plate 51 to separate the crushing roller 2 and the squeezing roller 3 and avoid mutual extrusion.

[0026] A lifting rod 7 is provided on the side of the slider 4, and a chute 8 matching the slider 4 is arranged inside the housing 1; the slider 4 is pulled along the chute 8 by the lifting rod 7.

[0027] A push rod 52 is provided on the side of the protection insert plate 51; the protection insert plate 51 can be inserted between the slider 4 and the housing 1 or pulled out from between the slider 4 and the housing 1 through the push rod 52.

[0028] A side plate 53 is provided on the side of the protection insert plate 51, and the push rod 52 is arranged on the side plate 53; adding the side plate 53 can facilitate the application of force and reduce the risk of the protection insert plate 51 breaking.

[0029] A push-out spring 54 is arranged between the end of the protection insert plate 51 and the housing 1; when the slider 4 is pushed, the protection insert plate 51 can be pushed into between the slider 4 and the housing 1 under the action of the push-out spring 54.

[0030] A sliding plate 55 is provided on the protection insert plate 51, and the push-out spring 54 is arranged on the sliding plate 55; the existence of the sliding plate 55 can make the protection insert plate 51 receive force more evenly and facilitate the movement of the protection insert plate 51.

[0031] A slot 56 matching the side plate 53 is provided on the housing 1; the side plate 53 can be embedded into the housing 1 to avoid the structure protruding and reduce accidents.

[0032] A limiting shaft 9 is arranged inside the housing 1, and the slider 4 is sleeved on the limiting shaft 9; the limiting shaft 9 is used to protect the slider 4 and facilitate the slider 4 to disengage from the chute 8.

[0033] The crushing roller 2 and the extrusion roller 3 are provided with extrusion bumps 10; the powder coating is crushed by the mutual extrusion of the extrusion bumps 10 and the extrusion roller 3.

[0034] The technical effect of the present invention is that when the crushing device is not used, by using the protection device 5, the crushing roller 2 can be lifted to prevent the situation that the crushing roller 2 is always mutually extruded with the extrusion roller 3 under the action of the top pressure spring 6, and the service lives of the crushing roller 2 and the extrusion roller 3 can be effectively prolonged.

[0035] The present invention has been described exemplarily in combination with the accompanying drawings.
