[0016] An optical width meter 5 is installed in the middle of the first fixed bracket 3, and two sets of width adjustment components are arranged on the second fixed bracket 4. The two sets of width adjustment components correspond to a roller conveyor 1 respectively, and the width adjustment components include a driver, a lifting rod, a rectangular frame 11 and a pressure roller 12; the driver is fixedly installed on the second fixed bracket 4, and its output end is transmission-connected to the lifting rod; the lifting rod is vertically arranged, and its lower end is fixedly connected to the rectangular frame 11; the pressure roller 12 is a damping roller, which is installed at the bottom of the rectangular frame 11.

[0017] The optical width measuring device 5 and the two drivers are also electrically connected to the controller.

[0018] This device is arranged close to the extruder. During production, two roller conveyors 1 respectively convey a side wall component 2 forward, and the optical width meter 5 measures the width of the two side wall components 2 in real time and transmits the data to the controller; when the width deviation of the two side wall components 2 exceeds 2mm, the controller controls the width adjustment component on the wider side to start, and the driver drives the lifting rod to descend, and the lifting rod drives the pressure roller 12 to descend and contact with the wider side wall component 2, and the pressure roller 12 provides a greater friction force to the side wall component 2, so that the side wall component 2 on the front side of the pressure roller 12 is stretched and narrowed; when the width deviation of the two side wall components 2 does not exceed 2mm, the controller controls the above-mentioned width adjustment component to reset.
