AI Technical Summary

Technical Problem

Traditional vacuum packaging machines have vertical projection overlap between the heat sealing components and the conveyor track, which requires repeated opening and closing of the chamber door or the use of complex mechanical avoidance mechanisms when the packaging seat is loading and unloading materials. This reduces packaging efficiency and increases the time required to remove the Chinese herbal medicine pieces.

Method used

The hydraulic telescopic rod drives the movement of the mounting frame and heat sealing assembly, combined with the motor-driven guide rod and moving rod, to achieve linear movement of the packaging seat, avoiding obstruction of the packaging seat by the heat sealing assembly and simplifying the process of the packaging seat entering and exiting.

Benefits of technology

It improves the packaging efficiency of Chinese herbal medicine slices, reduces the time required to remove packaged Chinese herbal medicine slices, and enhances the overall efficiency of the packaging process.

Abstract

This utility model relates to the field of vacuum packaging device technology, and discloses a vacuum packaging device for traditional Chinese medicine decoction pieces, including: a base, a packaging device shell on the upper surface of the base, a first hydraulic telescopic rod in the upper part of the inner cavity of the shell, and a mounting frame connected to its bottom end. A second hydraulic telescopic rod inside the mounting frame has its bottom end penetrating through the bottom of the mounting frame and connected to a heat-sealing assembly. An air extraction pipe in the vacuum pump outlet of the inner cavity of the shell penetrates the surface of the heat-sealing assembly. A conveying chamber is opened in the conveying frame on the upper surface of the base, and a motor rotor is coaxially connected to a guide rod in the chamber. A moving rod is screwed onto the surface of the guide rod, and the output end of the moving rod is connected to a packaging seat. When the first hydraulic telescopic rod moves the mounting frame upward, the heat-sealing assembly can be pulled out from the packaging seat, avoiding obstruction of the packaging seat's movement. The motor drives the guide rod to rotate, causing the moving rod to move the packaging seat, which can remove the packaging seat from the packaging device, facilitating the removal of the packaged traditional Chinese medicine decoction pieces, reducing the medicine removal time, and improving packaging efficiency.
