Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be further described below.

As shown in fig. 1 and 2, the present invention provides a flexible plate roller, which comprises a roller 1 and a bracket 2; the roller 1 is detachably erected on the bracket 2 to realize rotation;

both sides of the roller 1 are provided with strip-shaped mortises 4; the mortises 4 are arranged around the circumference of the drum 1; the outer surface of the roller 1 is provided with an embedded groove 5 along the length direction of the roller 1; the clamping piece 3 is arranged at the notch of the embedding groove 5; the wall of the embedded groove 5 is provided with a clamping groove 6 matched with the clamping piece 3, the clamping piece 3 is inserted into the clamping groove 6, and the clamping piece 3 is inserted along the clamping groove 6.
