Traditional Chinese medicine decoction piece vacuum packaging and extracting tube

Abstract

The invention discloses a traditional Chinese medicine decoction piece vacuum packaging and extracting tube which is a vacuum packaging and extracting tube with sequentially arranged gas exhaust single tubes, extracts air, is matched with a sealing machine to extract step by step, realizes continuous extraction and extracts step by step. The traditional Chinese medicine decoction piece vacuum packaging and extracting tube is characterized in that a plurality of guide slots are formed in a fixed frame, wherein the guide slots are arranged at equal distance from one end of the fixed frame to theother end of the fixed frame; the guide slots are strip-shaped slots, and extend towards the other side from one side of the fixed frame; the fixed frame is of a U-shaped structure, and is provided with a downward opening; a through slot is formed in one side of the fixed frame; a row of fixed holes are formed in positions, close to the other side of the fixed frame, of the upper side of the fixed frame; the bottoms of a plurality of pull-back blocks are arranged in the guide slots in a one-to-one correspondence mode; the pull-back blocks are trapezoidal structures, wherein one trapezoidal surface of each trapezoidal structure faces upwards, and the other trapezoidal surface is positioned in each guide slot; the pull-back blocks are of hollow structures; sides, which correspond to the fixed frame, of the pull-back blocks are inclined surfaces; and protective pads are arranged on the inclined surfaces.

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. In particular, it relates to a vacuum packaging extraction tube in which a plurality of single air extraction tubes are arranged in sequence, and the air is extracted at the same time, and is gradually withdrawn in cooperation with a sealing machine, so as to realize continuous extraction and gradual withdrawal. Background technique [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 ba...

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
