Abstract
The invention relates to a vacuum chamber decompression buffer device of a vacuum packaging machine. The buffer device is installed on one side of a vacuum chamber and comprises an exhaust pipe connected with the vacuum chamber, wherein a vacuum pumping control valve is installed on the exhaust pipe, an air return pipe is connected on the exhaust pipe, an air return control valve is installed on the air return pipe, the air return pipe is also equipped with an air inlet sound elimination assembly, the sound elimination assembly comprises a casing connected with the air return control valve, and a plurality of air inlet sound elimination devices are installed on the casing. The vacuum chamber decompression buffer device of the vacuum packaging machine provided by the invention adds the air inlet sound elimination device assembly on the air return pipe, wherein the vacuum chamber will not be filled with air instantly or thus cause a "air explosion" phenomenon of the vacuum chamber when a bypass valve namely the air return control valve is opened, an air input amount of the air inlet sound elimination device assembly is small, and the device is equipped with a buffer effect. The vacuum chamber decompression buffer device of the vacuum packaging machine provided by the invention is simple in structure and convenient in installation, does not require addition of any kinds of assistant electric appliance control equipment, and only needs to be installed on an original pipeline; and a sharp "whistle" sound will not be sent by the air return pipe, so that double effects including effective sound elimination and ventilation are realized.
Description
Technical field
The present invention relates to vacuum packaging equipment technical field, particularly vacuum packing machine.
Background technology
Vacuum packing machine after completing to packaging bag attal at every turn, because internal vacuum chamber is still in vacuum state and negative pressure state, the door of whole vacuum chamber cannot directly be opened, vacuum must be utilized in vacuum chamber to be filled with air, to reach and ambient atmosphere pressure balanced, just by power or manual unlocking door for vacuum chamber.And be filled with air to vacuum chamber, install gate valve structure additional owing to adopting on pipeline, in the moment of opening gate valve, the internal state of vacuum chamber directly changes to standard atmosphere pressure condition from certain negative pressure.The hurried change of this air pressure often causes the cracking of packaging bag (papery), and material scatters, and pollutes, and works long hours and also can cause the destruction of vacuum chamber structure.
Summary of the invention
The applicant is for the above-mentioned shortcoming of prior art, carry out studying and improving, provide a kind of vacuum chamber pressure relief buffering mechanism of vacuum packing machine, it can realize the smooth variation of vacuum chamber internal gas pressure, avoid the destruction of causing packaging bag, extend the service life of vacuum chamber structure.
In order to solve the problem, the present invention adopts following scheme:
A kind of vacuum chamber pressure relief buffering mechanism of vacuum packing machine, described shock absorber is installed on the side of vacuum chamber, comprise the extraction pipe be connected with vacuum chamber, extraction pipe is provided with and vacuumizes control cock and be connected with muffler, muffler is provided with return-air control cock, described muffler is also provided with intake noise reduction assembly, and described sound attenuation assembly comprises the sleeve be connected with return-air control cock, sleeve is provided with multiple intake muffler.
Technique effect of the present invention is:
The present invention sets up intake muffler assembly on muffler, and when bypass valve and return-air control cock are opened, air can not be full of vacuum chamber instantaneously and cause " empty quick-fried " phenomenon of vacuum chamber, and the suction quantity of intake muffler assembly is little, with buffer action.Wherein the number of intake muffler can change according to the length of intake period, to reach best using state.Structure of the present invention is simple, easy for installation, without the need to increasing any ancillary apparatus control convenience, only need install on former pipeline.In the present invention, muffler can not produce sharp-pointed " whistle " sound, realize the double action of effective noise reduction and ventilation.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
As shown in Figures 2 to 4, the vacuum chamber pressure relief buffering mechanism of the vacuum packing machine of the present embodiment, shock absorber is installed on the side of vacuum chamber 1, comprise the extraction pipe 2 be connected with vacuum chamber 1, extraction pipe 2 is provided with and vacuumizes control cock 3 and be connected with muffler 4, muffler 4 is provided with return-air control cock 5, muffler 4 is also provided with intake noise reduction assembly 6, sound attenuation assembly 6 comprises the sleeve 61 be connected with return-air control cock 5, sleeve 61 is provided with multiple intake muffler 62.
The present invention sets up intake muffler assembly 6 on muffler 4, and when bypass valve and return-air control cock 5 are opened, air can not be full of vacuum chamber 1 instantaneously and cause " empty quick-fried " phenomenon of vacuum chamber 1, and the suction quantity of intake muffler assembly 6 is little, with buffer action.Wherein the number of intake muffler 62 can change according to the length of intake period, to reach best using state.Structure of the present invention is simple, easy for installation, without the need to increasing any ancillary apparatus control convenience, only need install on former pipeline.In the present invention, muffler can not produce sharp-pointed " whistle " sound, realize the double action of effective noise reduction and ventilation.
Above illustrated embodiment is better embodiment of the present invention, only be used for conveniently the present invention being described, not any pro forma restriction is done to the present invention, have in any art and usually know the knowledgeable, if do not depart from the present invention carry in the scope of technical characteristic, utilize the Equivalent embodiments that the done local of disclosed technology contents is changed or modified, and do not depart from technical characteristic content of the present invention, all still belong in the scope of the technology of the present invention feature.
