Description

Technical Field

[0001] The invention relates to the technical field of plate wear resistance testing, and in particular to a water-based UV light-cured antibacterial wear-resistant coating plate wear resistance testing device. Background Art

[0002] Water-based UV light-curing board is referred to as UV board, and UV paint is ultraviolet light-curing paint. After UV paint is applied on ordinary particleboard, rice density board and other boards, it is dried by ultraviolet light in the curing machine to form a UV board. It is non-volatile, non-toxic and environmentally friendly. After curing, it has good antibacterial effect and is an ideal decorative board. However, the curing of UV paint has high technical requirements for mechanical equipment processing. It is often incomplete due to insufficient curing time, or the paint surface fails due to over-drying. Therefore, it is necessary to conduct a wear test on the produced UV board to verify the curing effect; the UV board wear test device in the prior art only scratches the surface of the UV board, and does not detect the scratch state, so it is impossible to achieve effective wear detection. At the same time, if the degree of wear is directly observed by a camera, the observation accuracy does not meet the requirements. Summary of the invention

Then the plate 123 reaches the bottom of the camera 118, and the camera 118 is used to detect the degree of wear on the surface of the plate 123.

When the downward pressure rod 121 is pressed down, the transfer gear 205 meshes with the lower docking gear 117, and every two side gears 207 mesh with each other, and the sizes of the side steel brushes 206 and the side gears 207 increase successively, and the largest side gear 207 meshes with the central gear 204.

[0032] When the toggle rod 115 is disengaged from the groove wheel 104, the groove wheel 104 does not rotate, while the toggle rod 115 and the pressing drum 107 still rotate synchronously, and the protrusion of the pressing drum 107 begins to contact the pressing rod 121.

The lower docking gear 117 drives the transmission gear 205, the center gear 204 and the center steel brush 203 to rotate.

When the inner docking shell 306 contacts the edge of the plate 123, the outer powder spray shell 301 continues to descend, and the inner spring 307 between the outer powder spray shell 301 and the inner docking shell 306 is compressed. The airbag shell 303 squeezes the powder spray airbag 304, and the fluorescent powder in the powder spray airbag 304 is sprayed onto the surface of the plate 123 through the powder spray tube 305 and the powder spray nozzle 308. Subsequently, when the toggle rod 115 enters the groove of the groove wheel 104 again, the protrusion of the pressing drum 107 is separated from the lower pressure rod 121, and the return spring 302 rebounds, causing the outer powder spray shell 301 and the lower pressure rod 121 to rise and reset.

[0035] The working principle of the wear resistance testing device for a water-based UV light-cured antibacterial wear-resistant coating plate disclosed in the present invention is as follows: a plate 123 is placed on a placement frame 122, and a motor 105 rotates to drive a motor gear 106 to rotate, thereby driving a transmission gear 109 and a small gear 110 to rotate, thereby driving a large gear 108 and a lower pressure drum 107 to rotate, thereby driving an upper docking gear 116 and a lower docking gear 117 to rotate, and driving a transmission wheel 112 and an upper gear 113 to rotate through a transmission belt 111, thereby driving a toggle gear 114 and a toggle rod 115 to rotate, and the toggle rod 115 toggle the groove wheel 104 and the rotating frame 103 to rotate ninety degrees each time, and then the toggle rod 115 is separated from the groove wheel 104 and rotates idly by itself, and the rotating frame 103 drives the placement plate 12 ... The frame 122 and the plate 123 rotate 90 degrees. When the groove wheel 104 does not rotate, the position of the groove wheel 104 is stabilized by the triangular clamping block 119. When the groove wheel 104 rotates, the triangular clamping block 119 will be pressed down, and the clamping block spring 120 will be compressed. When the groove wheel 104 rotates 90 degrees, the clamping block spring 120 rebounds. When the toggle rod 115 is disengaged from the groove wheel 104, the groove wheel 104 does not rotate at this time, and the toggle rod 115 and the pressing drum 107 still rotate synchronously, and the protrusion of the pressing drum 107 begins to contact the pressing rod 121. The rotation of the pressing drum 107 will drive the pressing rod 121 to descend, and the pressing rod 121 drives the test box 201 to descend along the test frame 124, and the pressing spring 202 is compressed. When the toggle rod 115 enters the groove wheel 104 again, 04, the protrusion of the downward pressing drum 107 is disengaged from the downward pressing rod 121, and the downward pressing spring 202 rebounds, so that the test box 201 and the downward pressing rod 121 rise and reset. When the test box 201 is pressed down, the central steel brush 203 and several side steel brushes 206 are in contact with the surface of the plate 123, and the transmission gear 205 is meshed with the lower docking gear 117. The lower docking gear 117 drives the transmission gear 205, the central gear 204 and the central steel brush 203 to rotate, and the central gear 204 drives the largest side gear 207 to rotate, thereby driving all the side gears 207 to rotate synchronously, thereby driving all the side steel brushes 206 to rotate, and the wear resistance test of the surface of the plate 123 is performed through the side steel brushes 206 and the central steel brush 203; when the downward pressing rod 121 is pressed down, the central steel brush 203 and the side steel brushes 206 are in contact with the surface of the plate 123. The descent will also synchronously drive the outer powder spray shell 301 to descend along the powder spray frame 125, the return spring 302 is compressed, the outer powder spray shell 301 drives the inner docking shell 306 to descend synchronously, and when the inner docking shell 306 contacts the edge of the plate 123, the outer powder spray shell 301 continues to descend, the inner spring 307 between the outer powder spray shell 301 and the inner docking shell 306 is compressed, and the airbag shell 303 squeezes the powder spray airbag 304, and the fluorescent powder in the powder spray airbag 304 is sprayed onto the surface of the plate 123 through the powder spray tube 305 and the powder spray nozzle 308, and then when the toggle rod 115 enters the groove of the groove wheel 104 again, the protrusion of the downward pressing drum 107 is separated from the downward pressing rod 121, and the return spring 302 rebounds, causing the outer powder spray shell 301 and the downward pressing rod 121 to rise and reset.

[0036] That is, the plate 123 first arrives under the test box 201 , and after the test is completed, arrives under the outer powder spraying shell 301 to be sprayed with fluorescent powder, and then the plate 123 arrives under the camera 118 , and the camera 118 detects the degree of wear on the surface of the plate 123 .
