A plastic bag sealing and hot pressing device

Abstract

This utility model relates to the field of plastic bag processing technology and discloses a plastic bag sealing hot pressing device, which includes a worktable, a heat exchange mechanism above the worktable, a movable groove on the top surface of the worktable, and a positioning component on the upper part of the worktable; the heat exchange mechanism includes a motor, which is fixedly installed on the outside of the worktable, and a threaded rod is fixedly connected to the drive end of the motor. The threaded rod rotates inside the movable groove, and a convex block is threaded on the outside of the threaded rod. A guide plate is penetrated through the inside of the convex block; in this utility model, by starting the motor to control the rotation of the threaded rod, the convex block drives the L-shaped plate to move laterally, the L-shaped plate drives the heat exchange sleeve to move, and the rotating drum drives the heat exchange sleeve to rotate on the support shaft to contact the hot-pressed plastic bag. The rotating drum rotates and presses the plastic bag to seal by relying on friction, and the heat exchange sleeve is used to absorb the heat at the sealing point, effectively accelerating the cooling time at the sealing point and improving production efficiency.
