[0028] Working principle of a continuous cutting device for producing sealing strips:

[0029] When in use, the operator places the sealing strip between the two first conveying rollers 7 and the two second conveying rollers 12, and then starts the first motor 4 and the second motor 10.

[0030] The output end of the first motor 4 drives the first rotating rod 13 to rotate, and the first rotating rod 13 drives the first bidirectional screw 14 to rotate.

[0031] The output end of the second motor 10 drives the second rotating rod 17 to rotate, and the second rotating rod 17 drives the second bidirectional screw 18 to rotate. Under the action of the screw, the second bidirectional screw 18 drives the two second moving blocks 19 to move, and the two second moving blocks 19 move in opposite directions. The second moving blocks 19 drive the second housing 11 to move, and the second housing 11 drives the second conveying roller 12 to move, so that the two second conveying rollers 12 clamp the sealing strip.

[0032] Then, the third motor 16 is started. The output end of the third motor 16 drives the first conveying roller 7 to rotate. The first conveying roller 7 conveys the sealing strip. The sealing strip drives the second conveying roller 12 to rotate. The second conveying roller 12 drives the measuring end of the length measuring encoder 20 to rotate, so that the length measuring encoder 20 measures the horizontal output length. After the sealing strip is conveyed to the specified length, the controller controls the cylinder 3 to start. The output end of the cylinder 3 pushes the cutting blade 2 to move, so that the cutting blade 2 cuts the sealing strip.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
