Sliding opening sealing door for vacuum heat sealing device

Abstract

A sliding opening sealing door for a vacuum heat sealing device comprises a door body, a plurality of sliding seats are arranged on the two sides of the door body, a pair of connecting seats are arranged at the two ends of a moving plate of the sliding seats and fixedly connected with the door body, a sliding space is formed between the connecting seats and the moving plate, and second moving wheels are installed on the moving plate. The back of each connecting seat is provided with an air cylinder seat, each air cylinder seat is provided with a sealing cylinder, the telescopic rod end of each sealing cylinder penetrates through the corresponding air cylinder seat and extends into the corresponding sliding space, the telescopic rod end of each sealing cylinder is rotationally connected with a pressing wheel through a pressing shaft, and the pressing wheels and the second moving wheels are oppositely arranged. The telescopic rod end of the hydraulic cylinder is rotationally connected to the moving plate, the hydraulic cylinder enables the second moving wheel to abut against the sliding plate and slide in the direction of the sliding plate to achieve closing, and the sealing cylinder enables the door body to abut against and press the door body on the opening side of the heat sealing device through the pressing wheel so that sealing can be achieved. The sealing door is convenient and fast to open, and the convenient operation performance of the vacuum sealing device is greatly improved.
