[0032] A moving seat plate 9 is arranged in the machine cover 4, and a guide block 10 and a screw rod nut 11 are respectively connected to the left and right ends of the moving seat plate 9. A sliding hole matched with the guide slide rod 5 is formed in the guide block 10, the screw rod nut 11 is inserted into the moving groove 6 and matched with the transmission screw rod 7, so that under the driving of the screw rod motor 8, the moving seat plate 9 can move along the length direction of the transparent tile 100.

[0033] Referring to the accompanying drawings Figure 5 , and the accompanying drawings Figure 6 , a spraying pipe 12 is fixedly arranged on the moving seat plate 9, the end of the spraying pipe 12 is bent downward and arranged perpendicular to the length direction of the transparent tile 100, then a plurality of spray heads 13 are arranged at intervals on the lower surface of the spraying pipe 12 perpendicular to the length direction of the transparent tile 100, and the uniform spraying of paint or glue liquid to the upper surface of the transparent tile 100 can be realized through the equal interval arrangement of the plurality of spray heads 13. A material conveying pump 14 is arranged at the upper end of the spraying pipe 12, then a material storage tank 15 is arranged on the upper surface of the machine cover 4, and an extendable material conveying pipe 16 is connected between the material conveying pump 14 and the material storage tank 15. During the movement of the moving seat plate 9 along the length direction of the transparent tile 100, the paint or glue liquid in the material storage tank 15 can be pumped out through the material conveying pump 14 and the material conveying pipe 16, and then uniformly sprayed down by the plurality of spray heads 13.

[0034] A roller seat 17 is arranged right below the moving seat plate 9 at the front side of the spray pipe 12, and a plurality of springs 18 are connected between the upper surface of the roller seat 17 and the moving seat plate 9. A vertical rod 19 is fixedly connected to the upper surface of the roller seat 17 and penetrates the moving seat plate 9, and then an abutting wheel 20 is connected to the top end of the vertical rod 19, while a guide convex strip 401 is fixedly arranged on the top wall of the machine cover 4 and acts on the abutting wheel 20. The acting surface of the guide convex strip 401 that acts on the abutting wheel 20 is arranged with a middle horizontal low and two end horizontal high, and the middle segment and the two end segments are connected by an arc segment.

[0035] A needle roller 21 is arranged in the roller seat 17, and a large number of needle tips (not shown in the figure) are arranged on the roller body of the needle roller 21. The length of the needle tips is not more than half the thickness of the transparent tile 100, and the diameter is controlled to be between 0.1-0.5mm. Meanwhile, an inner recess ring 211 matching the cross section of the transparent tile 100 is arranged on the roller body of the needle roller 21, so that the needle roller 21 can press the transparent tile 100 on the conveying roller 3 without deviation. Roll shafts 22 are connected to both ends of the needle roller 21, and the roll shafts 22 are rotatably connected with the bearings at both lower ends of the roller seat 17, and then gears 23 are connected to the end portions of the roll shafts 22 that extend out of the roller seat 17.

[0036] Finally, a telescopic driving member 25 is fixedly arranged on the moving seat plate 9 at the rear side of the spray pipe 12. The telescopic driving member 25 can be one of a pneumatic cylinder, an electric push rod or a hydraulic telescopic rod. A strip plate 26 is connected to the lower end of the telescopic driving member 25 that penetrates the moving seat plate 9, and a smearing block 27 made of rubber material is detachably mounted on the lower surface of the strip plate 26. The smearing block 27 is arranged along the width direction of the transparent tile 100, and a trapezoidal opening matching the cross section of the transparent tile 100 is arranged on the lower surface of the smearing block 27, so that the smearing block 27 can always maintain an equal gap with the surface of the transparent tile 100 after being pressed down, and then the sprayed paint or glue is evenly smeared.

[0037] When the transparent tile is painted or glued after being roll-pressed and formed, the transparent tile is sent to the front of the machine cover 4 along the positioning circular table on the conveying roller 3. The lead screw motor 8 is started to move the moving seat plate 9 from one end to the other end of the opening of the machine cover 4 under the action of the transmission lead screw and the lead screw nut. During the movement of the moving seat plate 9, the abutting wheel 20 will move downward under the action of the guide convex strip 401 to overcome the action force of the spring 18, and then the whole needle roller 21 will be in close contact with the upper surface of the transparent tile 100.

[0038] Subsequently, the feed pump 14 is started to draw paint or glue from the paint tank 15, and the paint or glue is uniformly sprayed by the plurality of spray heads 13. During the continuous movement of the moving base plate 9, the gears 23 at both ends of the needle roller 21 engage with the rack 24, thereby driving the needle roller 21 to rotate synchronously with the movement, and a large number of pinholes are punched on the upper surface of the transparent tile 100 by the needle tips on the surface of the needle roller 21, so that the sprayed paint or glue can enter the pinholes. At the same time, after the paint or glue is sprayed on the surface of the transparent tile 100, the gap of about 1-2 mm between the transparent tile 100 and the moving base plate 9 is maintained by the downward movement of the wiping block 27 during the movement, and the paint or glue is uniformly coated on the upper surface of the transparent tile 100 by the action of the wiping block 27, and finally the transparent tile 100 is sent into the drying channel for drying and shaping. Example 2

[0039] Example 2 discloses a coating device in which the needle roller 21 is replaced based on the technical scheme in Example 1, and the same parts as in Example 1 are not described again.

[0040] In this example 2, the sand roller is arranged in the roller seat 17 to replace the needle roller 21, and a large number of small sanding protrusions are arranged on the surface of the sand roller, and the sand roller body is provided with an inner recess ring 211 matched with the cross section of the transparent tile 100, and the ring wall of the inner recess ring 211 is also provided with sanding protrusions.

[0041] The sanding roller used in this example 2 to replace the needle roller 21 can also roughen the surface of the transparent tile 100, and a large number of recessed holes are formed on the surface of the transparent tile 100 after the sanding roller treatment, and then part of the paint and glue can enter the recessed holes after the transparent tile 100 is coated with glue or paint, thereby improving the adhesion between the entire coating and the surface of the transparent tile 100.

[0042] The above is only a preferred embodiment of the present application, and is not intended to limit the present application, and any modification, equivalent replacement and improvement within the spirit and principles of the present application shall be included in the protection scope of the present application.
