The utility model discloses a batchable plastic pasting device relates to tooling technical field. The utility model discloses a base, both sides of base are all fixedly connected with spliced plate, the base top is provided with the pressure pasting subassembly, and the pressure pasting subassembly includes the pressing plate of setting in the spliced plate top. The utility model discloses a pressure pasting subassembly by setting up the pressing plate, screw rod and pressure block, and cooperate the internal thread hole on the base, has realized to the efficient, stable pressure bonding of guide rail workpiece and the patch, and the pressure is evenly transmitted to the pressing plate through the rotation screw rod drive pressure block and press down, thereby to the workpiece exerted sustained, stable pressure bonding force, this not only has reduced the labor intensity of operator significantly, more important is ensured that every patch can obtain consistent and sufficient pressure tightness, effectively avoided because of the problem such as not firm, blistering or peeling off of insufficient pressure or deviation leads to bonding, has promoted the reliability of pasting combination and product quality consistency greatly.
