Description

Technical Field

[0001] This utility model relates to the field of vacuum packaging machine technology, and more specifically, to an assembly component for heat sealing of a high vacuum pump. Background Technology

[0002] Vacuum packaging is an advanced packaging technology that removes and seals the air inside a packaging container to reduce oxygen content, inhibit microbial growth, and delay oxidation reactions, thereby extending the shelf life of the product. In this process, the vacuum pump, as the core power component of the vacuum packaging machine, directly affects the vacuum level, pumping speed, packaging efficiency, and the final product preservation quality.

[0003] The vacuum pump components used in existing vacuum packaging machines are relatively simple, making it difficult to guarantee a stable vacuum level during actual use, which directly affects the packaging efficiency and packaging effect of the vacuum packaging machine.

[0004] In view of this, we have studied and improved the existing problems to provide an assembly component for heat sealing of a high vacuum pump. The aim of this technology is to solve the problems and improve its practical value. Utility Model Content

[0006] To achieve the above objectives, this utility model provides an assembly component for heat sealing of a high vacuum pump, which is accomplished by the following specific technical means:

[0007] An assembly component for heat sealing a high vacuum pump includes: a vacuum pump, a vacuum pump filter, a first three-way valve, a first vacuum valve, a third vacuum valve, a negative pressure gas tank, a filter, a second vacuum valve, a second three-way valve, and a vent valve; the vacuum pump filter is fixedly mounted on the vacuum pump, and the vacuum pump filter is connected to the first vacuum valve and the third vacuum valve through the first three-way valve; the other end of the first vacuum valve is connected to the outlet end of the negative pressure gas tank; a filter is fixedly mounted on the inlet end of the negative pressure gas tank; the filter is connected to the second vacuum valve, and the second vacuum valve is connected to the vent valve and the third vacuum valve through the second three-way valve.

[0008] As a further optimization of this technical solution, the other end of the venting valve of the assembly component for heat sealing of a high vacuum pump of this utility model is connected to the vacuum chamber of a vacuum packaging machine through an air pipe.

[0009] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0010] 1. This utility model, by setting up a negative pressure gas tank, opens the first and second vacuum valves during vacuuming, drawing gas from the vacuum chamber while simultaneously creating negative pressure in the negative pressure gas tank, ensuring the vacuum level in the vacuum chamber during heat sealing, and improving packaging efficiency and packaging effect.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figures 1 to 2 This utility model provides a specific technical implementation scheme for an assembly component for heat sealing of a high vacuum pump:

[0018] An assembly component for heat sealing a high vacuum pump includes: a vacuum pump 1, a vacuum pump filter 2, a first three-way valve 3, a first vacuum valve 4, a third vacuum valve 5, a negative pressure gas tank 6, a filter 7, a second vacuum valve 8, a second three-way valve 9, and a vent valve 10; the vacuum pump filter 2 is fixedly mounted on the vacuum pump 1, and the vacuum pump filter 2 is connected to the first vacuum valve 4 and the third vacuum valve 5 through the first three-way valve 3; the other end of the first vacuum valve 4 is connected to the outlet end of the negative pressure gas tank 6; the inlet end of the negative pressure gas tank 6 is fixedly mounted with a filter 7; the filter 7 is connected to the second vacuum valve 8, and the second vacuum valve 8 is connected to the vent valve 10 and the third vacuum valve 5 through the second three-way valve 9; the other end of the vent valve 10 is connected to the vacuum chamber of a vacuum packaging machine through an air pipe.

[0019] Specific implementation steps:

[0020] After the upper chamber of the vacuum packaging machine falls, the equipment operates in the vacuuming stage. Initially, the first vacuum valve 4 is normally open, and the second vacuum valve 8 and the third vacuum valve 5 are normally closed. During vacuuming, the first vacuum valve 4 and the second vacuum valve 8 are open. After the set valve opening time is up, the first vacuum valve 4 and the second vacuum valve 8 close while the third vacuum valve 5 opens. After the set valve opening time is up, the third vacuum valve 5 closes while the first vacuum valve 4 opens. Then, after the sealing and cutting time is up, the venting valve 10 opens. This is one step of heat sealing vacuum.

[0021] In summary, this high-vacuum pump heat-sealing assembly component, by incorporating a negative pressure gas tank, allows the first and second vacuum valves to open during vacuuming. This simultaneously extracts gas from the vacuum chamber and creates negative pressure in the gas tank, ensuring the vacuum level within the chamber during heat sealing and improving packaging efficiency and effectiveness. Through improvements to the high-vacuum pump heat-sealing assembly component, it achieves a reasonable structural design, simultaneously extracting gas from the vacuum chamber and creating negative pressure in the gas tank, ensuring the vacuum level within the chamber during heat sealing, and improving packaging efficiency and effectiveness. This effectively solves the problems and shortcomings of existing technologies and equipment.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
