Wherein, the core plate extrusion molding link can specifically include:
step S11: a continuously extruded and pre-shaped strip of core board is obtained.
Please refer to fig. 1. An extrusion apparatus 10 may be used to continuously extrude core material, such as PE (polyethylene) plastic pellets, into a pre-formed PE plastic core. The pre-shaped PE plastic core board is finally shaped in the subsequent compounding process with the aluminum material to form the high-pressure low-density PE plastic core board.

Thus, the distance between two adjacent aluminum coil edge tracking sensors on one side of the operation line of the plate chain conveyor is 1000mm, and two Y linear axes are formed on two sides of the operation line.
When 23 front ends of aluminum-plastic composite panel strips with aluminum skins exposed outside after slotting are advanced to a punching machine station, the first group of 2 aluminum roll edge tracking sensors detect the aluminum skins and feed back the aluminum skins to a positioning induction system to position the initial position, and the second group of 2 aluminum roll edge tracking sensors feed back the aluminum skins to the positioning induction system when detecting the aluminum skins, wherein the distance between the two groups of edge tracking sensors is just consistent with the punch length (namely the fixed length) of the punching machine. The positioning sensing system feeds back to a digital control computer (host), a control instruction sent by the digital control computer directly drives the punching machine to generate mechanical motion, and the punching machine starts to move for the first time from a moving initial position (punching a suspension portion 2331 with the fixed length of 1000 mm). After the first punching, the punch quickly returns to the initial position and starts to punch again (punch a second 1000mm long overhang 2331 and end-to-end with the first 1000mm long overhang 2331).
