The invention relates to a device for overlapping when a plastic extruder has a broken strip. The device for overlapping the broken strip of the plastic extruder comprises a plastic extruder head (8) and a cooling water groove (3) positioned in the lower part of the extruder head (8); one side of a strip bracket (5) traversing two sides of the cooling water groove (3) is provided with a vertical cylinder (2); the end part of a push rod of the vertical cylinder (2) is connected with a horizontal cylinder (1); the direction of a push rod of the horizontal cylinder (1) is consistent with the length direction of the strip bracket (5); and the end tip of the push rod of the horizontal cylinder (1) is provided with a rotary baculiform scraper (6) which is driven by a minitype motor (7). The device has a simple and reliable structure, avoids the scalding accident generated by manual overlapping and overcomes the disadvantages that in the prior art, a metal strip is inadvertently dipped on a strip material during overlapping and damages subsequent machines and equipment, thereby ensuring that a plastic granular product is not intermixed with metal chipping.
