Multifunctional vacuum packaging machine

Abstract

The invention relates to the technical field of vacuum packaging, and discloses a multifunctional vacuum packaging machine. The multifunctional 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 heating system, a vacuum pump set and a control system are arranged on the base, the heating system comprises a heater and a pressing strip, the heater is arranged on the base and located outside the lower cavity, the pressing strip is arranged on the top cover and located outside the upper cavity, 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 multifunctional vacuum packaging machine, the arrangement position of the heating system is optimized, inner pumping and outer pumping of a vacuum packaging bag can be achieved simultaneously, practicability is high, use is convenient, popularization is easy, meanwhile, the volume of a vacuum cavity is reduced, the power requirement of the vacuum pump set is lowered, and control over the manufacturing cost is facilitated.

Description

technical field [0001] The invention relates to the technical field of vacuum packaging, in particular to a multifunctional vacuum packaging machine. Background technique [0002] Vacuum packaging machines are often used for sealed packaging of items, such as 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. Part of the space around 200 cannot be used, and this part of the space increases the chamber volume of the vacuum chamber virtually. An excessively large vacuum chamber puts forward greater requirements for the power of the vacuum pump group, and the high-power vacuum pump group further leads to The production cost of the multi-functional vacuum packaging machine has been high. In addition, the heater 200 is installed in the vacuum chamber 100, so there is no problem when the vacuum packaging bag is pumped inside. However, if the vacuum packaging...

[0002] Vacuum packaging machines are often used for sealed packaging of items, such as 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. Part of the space around 200 cannot be used, and this part of the space increases the chamber volume of the vacuum chamber virtually. An excessively large vacuum chamber puts forward greater requirements for the power of the vacuum pump group, and the high-power vacuum pump group further leads to The production cost of the multi-functional vacuum packaging machine has been high. In addition, the heater 200 is installed in the vacuum chamber 100, so there is no problem when the vacuum packaging bag is pumped inside. However, if the vacuum packaging machine is used for external pumping, the heater The space next to the 200 will cause a gap between the heater 200 and the edge of the vacuum packaging machine. The vacuum packaging bag needs to put most of the bag body into the vacuum chamber 100 to complete the external pumping, and the length of the vacuum packaging bag is higher. In addition, the usable area of ​​the vacuum packaging bag is also virtually reduced. At the same time, the height of the heater 200 is inconsistent with the height of the end of the vacuum packaging machine. , which limits the use scenarios of vacuum packaging machines, which is not conducive to the promotion of vacuum packaging machines
