Idler set 231 and pinch roller set 232 are driven by a motor. In order to simplify the structure, the riding wheel set 231 can be set as a driving wheel, the pressing wheel set 232 is a driven wheel, that is, the motor only drives the riding wheel set 231, and the pressing wheel set 232 is driven to rotate by the friction force between the riding wheel set 231 and the motor.

The edge banding material travels forward by friction provided by the rotating stationary idler set 231 and pinch set 232. The rotation directions of the carrier roller set 231 and the pressing roller set 232 are opposite to each other so as to drive the edge sealing raw material to advance.

Meanwhile, the width of the flattened edge sealing raw material can be adjusted by adjusting the distance between the plane where the first bearing group is located and the plane where the riding wheel group 231 or the pressing wheel group 23 is located, that is, the adjustment of the width of the turned edge is realized.

The driving motor drives one riding wheel set 231 or the knurled riding wheel 242 through the speed reducer 1 to realize the driving of all the riding wheel sets 231 and the knurled riding wheel 242, and the rotating speeds of the riding wheel sets 231 and the knurled riding wheel 242 are the same, so that the edge sealing raw material can stably run, and the device is simplified.

The roll collar device 3 comprises a roll collar seat 31, a pressure head 32 arranged on the roll collar seat 31, a straightening wheel 34 and two roll collar riding wheel groups 33. The straightening wheels 34 are rotatably mounted on the ring roller seats 31 and the two ring roller sets 33 are rotatably mounted on the ram 32. The two roller ring idler groups 33 are positioned above the straightening wheel 34, the straightening wheel 34 is positioned between the two roller ring idler groups 33, the centers of the two roller ring idler groups 33 are positioned on the same horizontal plane, and the horizontal distance between the center of the straightening wheel 34 and the center of the roller ring idler group 33 is smaller than the sum of the radiuses of the straightening wheel and the roller ring idler group. The edge sealing raw material firstly passes through a gap between one roller ring carrier group 33 and the straightening wheel 34 and then passes through a gap between the other roller ring carrier group 33 and the straightening wheel 34 to form a circular ring shape.

In order to realize the processing of circular rings with different diameters, the position of the roller ring idler group 33 is adjustable in the direction vertical to the horizontal plane. The position adjustment or movement mode of the roller ring idler group 33 can adopt the hydraulic drive, the screw drive and other modes in the prior art, for example, the hydraulic device or the screw structure is directly connected and drives the pressure head 32 to move, and the details are not repeated herein.

The driving motor drives the roller ring riding wheel set 33 to rotate through the speed reducer 1. Specifically, the connecting shaft of the speed reducer 1 is mounted in a speed reducer sleeve 351, one end of the rotating shaft of the roller ring idler group 33 is fixedly connected with the second chain wheel 352, the other end of the rotating shaft of the roller ring idler group 33 is fixedly connected with the roller ring idler group 33, and the connecting shaft of the speed reducer 1 is connected with the second chain wheel 352 through a second roller chain 353.

As can be seen from the above, the burring and knurling device 2 and the roller ring device 3 are driven by a drive motor.

The working process of the invention is as follows: one end of the edge sealing raw material is placed between the supporting roller set 231 and the pressing roller set 232 at one end of the flanging and knurling device 2, so that the edge sealing raw material is not completely placed between the supporting roller set 231 and the pressing roller set 232 in the width direction. Opening the flanging rounding machine, the riding wheel group 231 and the pinch roller group 232 rotate and compress the edge sealing raw material, the edge sealing raw material is driven to move forwards through friction force, the edge sealing raw material enters the edge distance adjusting device 22, one side edge of the edge sealing raw material, which is far away from the riding wheel group 231 or the pinch roller group 232, contacts the first bearing group, and under the action of the blocking force of the first bearing group, the side edge is turned upwards to form a turned edge. The edge sealing raw material continues to move forward, the width of the area of the edge sealing raw material compressed by the flanging wheel set is gradually increased, after passing through the multiple flanging wheel sets and the edge distance adjusting device 22, a turned edge with a designed width is formed, and meanwhile, the circular ring shape is flattened. After the edging material passes through the knurl wheel set 24, the compressed face of the edging material is embossed and a bead is formed. The edge sealing raw material forming the edge curling continuously enters the roller ring device 3 and sequentially passes through the straightening wheel 34 and one roller ring riding wheel group 33 and between the straightening wheel 34 and the other roller ring riding wheel group 33 to form a circular ring shape with the edge curling. When the curling width and the diameter of the circular ring need to be changed, the curling width is adjusted by the edge distance adjusting device 22, and the diameter of the circular ring is adjusted by adjusting the height of the roller ring riding wheel set 33.

Finally, it must be said here that: the above embodiments are only used for further detailed description of the technical solutions of the present invention, and should not be understood as limiting the scope of the present invention, and the insubstantial modifications and adaptations made by those skilled in the art according to the above descriptions of the present invention are within the scope of the present invention.
