Vacuum packaging machine

Abstract

The invention relates to the technical field of vacuum packaging, and discloses a vacuum packaging machine. The vacuum packaging machine comprises a base and a top cover which are connected in a hinged mode, wherein a lower cavity is formed in the top face of the base, an upper cavity is formed in the bottom face of the top cover, a heater, a vacuum pump set and a control system are arranged on the base, the vacuum pump set communicates with the lower cavity through an extraction opening formed in the cavity wall of the lower cavity, and the control system is used for controlling the heater and the vacuum pump set to complete heat sealing and suction operation. According to the vacuum packaging machine, stress conditions of the cavity wall of the upper cavity and the cavity wall of the lower cavity of the vacuum packaging machine are improved, the material consumption and the manufacturing process of the cavity walls of the upper cavity and the lower cavity of the vacuum packaging machine are optimized, the material consumption cost and the process cost are reduced, meanwhile, the volume of the vacuum cavity is reduced, the selection cost of the vacuum pump set is reduced, and the manufacturing cost of the vacuum packaging machine is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of vacuum packaging, in particular to a vacuum packaging machine. Background technique [0002] Vacuum packaging machines are often used for sealed packaging of articles. The existing cavity-type vacuum packaging machines are made of metal materials in consideration of pressure requirements. The processing technology is complicated and the production cost is high. At the same time, if figure 1 As shown, the shape of the vacuum chamber 100 in the prior art is limited by the processing technology, and the shape of the vacuum chamber 100 is relatively square. The multiple edge corners of the vacuum chamber 100 cannot play the role of accommodating the vacuum packaging bag, and the vacuum chamber is virtually enlarged. The volume, too large vacuum chamber puts forward greater requirements on the power of the vacuum pump group, and the high-power vacuum pump group further leads to an increase in the production co...

Problems solved by technology

[0002] Vacuum packaging machines are often used for sealed packaging of articles. The existing cavity-type vacuum packaging machines are made of metal materials in consideration of pressure requirements. The processing technology is complicated and the production cost is high. At the same time, if figure 1 As shown, the vacuum packaging machine in the prior art is limited by the processing technology, the shape of the vacuum chamber 100 is relatively square, and the multiple edge corners of the vacuum chamber 100 cannot play the role of accommodating the vacuum packaging bag, which virtually increases the vacuum chamber. The volume of the vacuum chamber is too large, which puts forward greater requirements on the power of the vacuum pump group, and the high-power vacuum pump group further leads to an increase in the production cost of the vacuum packaging machine, which is not conducive to the production and use of the vacuum packaging machine.
