[0017] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] The present invention provides a self-channeling device for the water roller of the plate, such as Figure 1 As shown, a self-channeling device 5 is added inside the water roller 4. The self-channeling device 5 can increase the axial reciprocating motion of the water roller 4 on the basis of the original rotational motion, so as to better level the water content.

[0019] Example 1

[0020] like Figure 1 As shown, the two shaft ends of the water roller 4, the water roller shaft end 3 and the self-channeling device shaft end 6 are respectively installed on the transmission surface bracket 2 and the operating surface bracket 7 on the inner side of the wall panel 1 and the wall panel A19. The transmission surface bracket 2 reserves the gap required for the reciprocating motion of the water roller 4, that is, the sliding groove. The operating surface bracket 7 is fixed, that is, the self-channeling device shaft end 6 is fixedly connected to the operating surface bracket 7;

[0021] Example 2

[0022] like Figure 2As shown, the water roller 4 is coaxially fixed with the sleeve 8 in the self-channeling device 5. When the water roller 4 rotates, the sleeve 8 also rotates with it; when the sleeve 8 rotates, the sleeve gear 9 embedded in the sleeve 8 drives the gear 10 to rotate. The gear 10 is installed on the shaft 16 through the eccentric sleeve 17. The shaft 16 is coaxially installed in the sleeve 8, and one side of the gear 10 is always engaged with the sleeve gear 9 to form an eccentric gear. The joint cylinder 11 sleeved on the other end of the shaft 16 offsets the influence of the eccentric sleeve 17 on the roller drive sleeve 12, ensuring that the center line of the roller drive sleeve 12 and the shaft 16 are aligned. The roller drive sleeve 12 is sleeved on the end of the shaft 16 near the water roller 4; because the number of teeth on the gear 10 is less than that on the sleeve gear 9, there is a speed difference between the two (the bevel gear has a higher speed); the gear 10 drives the roller drive sleeve 12 to rotate, and the roller support shaft 13 rotates together with the roller drive sleeve 12 through a threaded connection. The roller support shaft 13 is located at the connection between the sleeve 8 of the self-channeling device 5 and the inside of the water roller 4; the other end of the roller support shaft 13 near the water roller 4 is equipped with a cam follower bearing 15, the outer cylindrical surface of which contacts the sleeve end face cam 18 and the end face cam 14 respectively;

[0023] Example 3

[0024] While the roller support shaft 13 drives the cam follower bearing 15 to rotate, it drives the internal structure of the self-running device 5, including the roller support shaft 13, roller drive sleeve 12, shaft 16, joint cylinder 11, eccentric sleeve 17, gear 10, etc., to perform axial reciprocating motion along the end face cam 14 and the sleeve end face cam 18; because the self-running device 6 is fixed on the bracket and cannot move axially, the axial reciprocating motion of the internal structure of the self-running device 5 is converted into the axial reciprocating motion of the sleeve 8, thereby driving the plate-forming water roller 4 to perform axial reciprocating motion.
