A vacuum packaging extraction tube for Chinese herbal decoction pieces

Abstract

The invention discloses a vacuum packaging extraction tube for decoction pieces of traditional Chinese medicine, which discloses a vacuum packaging extraction tube in which a plurality of suction single tubes are arranged sequentially, and the air is extracted at the same time, and is gradually withdrawn in cooperation with a sealing machine, so as to realize continuous extraction and gradual withdrawal. It is characterized in that a plurality of guide grooves are opened on the fixed frame, and are arranged equidistantly along one end of the fixed frame to the other end, and the described guide grooves are bar-shaped grooves, and the guide grooves are arranged along one side of the fixed frame to the other end. Extending in the direction of the side, the fixed frame is a U-shaped structure with the opening facing downwards, a through groove is opened on one side of the fixed frame, and a row of fixing holes is opened on the upper side of the fixed frame close to the other side of the fixed frame , the bottoms of a plurality of pullback blocks are placed in a plurality of guide grooves one by one, the pullback block is a trapezoidal structure, and one trapezoidal surface faces upward, and the other trapezoidal surface is located in the guide groove, and the pullback block is hollow structure, the side of the pull-back block corresponding to the fixed frame is an inclined surface, and a protective pad is placed on the inclined surface.

Description

technical field [0001] The invention relates to an extraction tube for vacuum packaging of decoction pieces of traditional Chinese medicine, which relates to an extraction tube for gradually and continuously extracting the air in the package when the decoction pieces of Chinese medicine are vacuum packaged, and belongs to the field of traditional Chinese medicine processing.

Problems solved by technology

[0002] At present, after the processing of traditional Chinese medicine decoction pieces, it is generally necessary to carry out vacuum packaging to avoid dampness of the traditional Chinese medicine decoction pieces, which will affect the use. Put air into the packaging bag to achieve the purpose of vacuum packaging. When pumping air, the width of the suction pipe will affect the sealing operation. Therefore, it is necessary to withdraw the suction pipe before sealing, or directly on the side of the suction pipe mouth. Sealing makes the extraction time of the exhaust pipe shorter, and the air cannot be exhausted. Prolonging the extraction time will lead to a decrease in sealing efficiency. It cannot cooperate with the sealing equipment for gradual withdrawal and continuous extraction, and the existing exhaust pipe is mainly a round tube. , although the round tube has a large cross-sectional area, it can also suck in a lot of dregs, which is easy to block the pumping pipe, and the pumping channel is single. After the vacuum tube is pulled out, sealing it will make part of the gas out of the pumping tube. Into the package, affect the quality

[0003] Publication number CN204150267U discloses a structure of a vacuum pumping pipe, which includes a horizontally arranged connecting pipe body arranged above the workbench and suspended on the wall. The left and right ends of the connecting pipe body are closed, and the middle part of the upper end is provided with Connecting port A, the lower end is provided with several connecting ports B connected with flexible pipes, one end of the flexible pipe is connected with the connecting port B, the other end is connected with one end of the valve body, and the other end of the valve body is provided with a pump The air-packed mouth, the device uses dual channels for vacuuming, but it still cannot form a cooperation with the sealing machine, and the suction pipe is gradually withdrawn, which affects the synchronization of the sealing operation and the pumping, and the vacuuming operation. Continuous, and the orifice is round
