The two pressing strips 446 are arranged above the lower scissors in parallel at intervals, two ends of the upper scissors 441 are arranged along the two pressing strips 446 in a sliding mode respectively, and the upper scissors 441 are connected with a return spring. The oil cylinder shaft 434 is connected with the sliding knife rest 445 and drives the sliding knife rest 445 to slide along the two pressing strips 446 to press the upper scissors 441 downwards, the upper scissors 441 move downwards to be connected with the lower scissors to realize cutting, and when the sliding knife rest 445 is separated from the upper scissors 441, the upper scissors 441 are separated from the lower scissors under the action of the return spring.

The working process of the invention is as follows: the edge sealing raw material 0 is wound on the material placing frame 1, and the edge sealing raw material 0 with different widths and the edge sealing raw material 0 with different lengths can be placed by adjusting the position of the clamping frame 14 and the position of the expansion block 13. When the edge sealing device is used, the free end of the edge sealing raw material 0 is pulled out and 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 0 is not completely placed between the supporting roller set 231 and the pressing roller set 232 in the width direction. Open turn-ups rounding machine, riding wheel group 231 and pinch roller set 232 rotate and compress tightly banding raw materials 0, move ahead through frictional force drive banding raw materials 0, and banding raw materials 0 gets into a margin to adjusting device 22, and its a side contact first bearing group of keeping away from riding wheel group 231 or pinch roller set 232, under the effect of the barrier force of first bearing group, the side turns over a formation turn-up that turns over. The edge sealing raw material 0 continues to move forward, the width of the area of the edge sealing raw material 0 compressed by the flanging wheel set is gradually increased, and when the edge sealing raw material 0 passes through the knurling pressing wheel set 24, the compressed surface of the edge sealing raw material 0 is embossed and forms a turned edge. The edge sealing raw material 0 forming the edge curling continuously moves into the roller ring device 3, 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 ring shape with the edge curling, and is finally cut by the cutting machine 4 to connect the cut parts to form edge sealing.

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.
