Full-automatic sealing machine with error contact protection device

Abstract

The invention discloses a full-automatic sealing machine with an error contact protection device, and belongs to the technical field of sealing machine safety. The full-automatic sealing machine comprises a film pressing mechanism, a film supporting rod, a lower die capable of moving front and back along a guide rail and a microswitch, and the microswitch is electrically connected with a sealing machine main machine board. The full-automatic sealing machine is characterized in that a motion line is in lap joint with the front end of the film supporting rod in a contact manner, the film supporting rod and the motion line are thin rods made of metal materials, the two ends of the motion line can be separated from the film supporting rod when the motion line bears external force, the film supporting rod, the motion line, the microswitch and the main machine board are connected through wires in series to form a normally closed loop, when the microswitch is touched or the motion line is separated from the film supporting rod, the loop is opened, the main machine board controls the film pressing mechanism to rise to a preset positioning point, and the lower die retreats back to the preset positioning point. By means of the full-automatic sealing machine, industrial accidents can be accurately avoided during risk operation, normal film replacement and other work can be conveniently carried out, and the beneficial effects of being simple in structure and convenient to use are achieved.

Description

technical field [0001] The invention belongs to the technical field of sealing machine safety, in particular to an automatic sealing machine with a false touch protection device. Background technique [0002] Existing full-automatic sealing machine for milk tea generally comprises a frame and a laminating mechanism, a film rolling mechanism and an in-and-out mechanism installed on the frame, and the function of sealing is achieved through the cooperation of each part. When working, place the container to be sealed in the lower mold of the in-out mechanism, the lower mold enters the lower part of the lamination mechanism along the guide rail, and at the same time the lamination mechanism goes down, and seals the sealing film between the two supporting film rods on the edge of the container opening After the sealing action is completed, under the action of the motor, the laminating mechanism moves upward, and the lower mold and the sealed container exit for easy access.

AI Technical Summary

Problems solved by technology

[0003] In order to prevent the hand of the sealing machine operator from being brought into the body by the platform and causing injury, the existing sealing machine is equipped with a false touch sensor stop device, and its structure is generally a combination of a baffle and a micro switch. Such a structure Economical and reliable, widely used, but limited to one-way induction, which cannot meet the functional requirements of new sealing machine products

Since the commonly used structure can only move in one direction, it is not easy to install a new sealing film, and it is easy to cause safety accidents when emergency treatment occurs when the film is broken or the cup is not well sealed during operation.
