[0021] The following combines the accompanying drawings and embodiments to further describe in detail the specific implementation manners of the present utility model.

[0022] As Figures 1 to 3 shown, an embodiment of the present disclosure provides an environmental protection stone paper paper defect detection device, and the environmental protection stone paper paper defect detection device includes a support base 10 and a detection platform 20. Among them, a support surface 111 is provided on the support base 10 for supporting the detection platform 20, and the support surface 111 can be inclined relative to the horizontal plane. The detection platform 20 includes a light-emitting part 21 and a cover body 22. The light-emitting part 21 includes a groove body 211 with an open top, a light homogenizing plate 212 covering the top opening of the groove body 211, and a light source 213 in the groove body 211. The detection platform 20 further includes a cover body 22. The cover body 22 includes a top plate 221 and a side plate 222. The cover body 22 is buckled on the light-emitting part 21, and a detection port 221A for partially exposing the light homogenizing plate 212 is provided on the top plate 221.

[0023] In the environmental protection stone paper paper defect detection device provided in this embodiment, the support surface 111 can be inclined relative to the horizontal plane, so that the detection platform 20 placed on the support surface 111 is also inclined relative to the horizontal plane. The stone paper can be placed on the light homogenizing plate 212, so that the stone paper is inclined relative to the human eye. The light source 213 passes through the stone paper after being homogenized by the light homogenizing plate 212, so that it is convenient for the operator to clearly observe defects such as black spots and coking impurities on the paper surface with the naked eye. The detection port 221A formed by the top plate 221 can play a certain limiting role on the stone paper to prevent the stone paper from sliding out of the detection platform 20. The cover body 22 is buckled on the light-emitting part 21, which is convenient for disassembly. The cover body 22 with a suitable detection port can be replaced according to the size of the stone paper to be defect-detected, with high flexibility and wide application range.

[0024] In one embodiment, the inclination angle of the support surface 111 relative to the horizontal plane can be a fixed angle, for example, it can be 45°. In another embodiment, as Figure 3As shown, the support base 10 includes a first support plate 11 and a second support plate 12 that are rotatably connected. An angle adjustment mechanism is provided between the first support plate 11 and the second support plate 12. The angle adjustment mechanism is used to adjust the angle between the first support plate 11 and the second support plate 12. The surface of the first support plate 11 facing away from the second support plate 12 constitutes the support surface 111. In this way, the inclination degree of the first support plate 11 can be adjusted by the angle adjustment mechanism, and then the inclination angle of the detection platform 20 can be adjusted to facilitate the operator to adjust a suitable angle for defect detection.

[0025] In one embodiment, one end of the first support plate 11 is rotatably connected to one end of the second support plate 12 through a rotating shaft 13. One end of the angle adjustment mechanism is fixedly connected to the other end of the second support plate 12, and the other end of the angle adjustment mechanism is slidably connected to the side of the first support plate 11 facing away from the support surface 111.

[0026] In one embodiment, the angle adjustment mechanism includes a telescopic structure 14. When the telescopic structure 14 extends, the angle between the first support plate 11 and the second support plate 12 increases. When the telescopic structure 14 contracts, the angle between the first support plate 11 and the second support plate 12 decreases.

[0027] In one embodiment, the telescopic structure 14 can be an electric telescopic rod, and the angle between the first support plate 11 and the second support plate 12 can be conveniently adjusted by the electric telescopic rod. In another embodiment, as Figure 3 shown, the telescopic structure 14 includes a corrugated plate 141. The corrugated plate 141 encloses to form a telescopic structure 14 with a cavity. An air outlet 141A and an air inlet 141B are provided on the corrugated plate 141. A one-way valve 15 is provided on the air outlet 141A. The one-way valve 15 is configured to only allow gas to be discharged from the cavity 142. A blocking portion 16 is provided on the air inlet 141B. The blocking portion 16 is used to open and block the air inlet 141B. In this way, when the first support plate 11 is pressed, the cavity 142 is pressurized to exhaust gas through the one-way valve 15, so that the telescopic structure 14 contracts, and thus the angle between the first support plate 11 and the second support plate 12 decreases. When it is necessary to increase the angle between the first support plate 11 and the second support plate 12, the blocking portion 16 can be opened to open the air inlet 141B. Under the action of the air pressure difference, external gas enters the cavity 142, so that the telescopic structure 14 extends, and the operation is convenient.

[0028] In one embodiment, a spring is provided in the cavity. When the telescopic structure 14 contracts, the spring is compressed, so as to provide assistance when it is necessary to increase the angle between the first support plate 11 and the second support plate 12, and ensure that the telescopic structure 14 can extend smoothly.

[0029] In one embodiment, the groove body 211 is fixedly connected to the support surface 111, and the cover body 22 is in a tight fit with the groove body 211, so as to facilitate the replacement of the cover body 22.

[0030] In one embodiment, the environmental protection stone paper sheet defect detection device further includes a lifting mechanism, the support seat 10 is arranged on the lifting mechanism, and the lifting mechanism is used to lift the support seat 10. The height of the detection platform 20 can be conveniently adjusted by the lifting mechanism to adapt to operators of different heights.

[0031] The above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Those of ordinary skill in the relevant technical fields can also make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention, and the patent protection scope of the present invention should be defined by the claims.
