Vacuum sealing packaging machine

Abstract

The invention discloses a vacuum-sealing packaging machine comprising a frame, a conveying mechanism, a sealing mechanism, a feeding mechanism and a discharging mechanism. The conveying mechanism comprises an annular track, a transmission chain plate and a drive device. The sealing mechanism comprises fixed active vacuum front chambers and movable passive vacuum rear chambers, the fixed active vacuum front chambers are fixed on the frame, and the movable passive vacuum rear chambers are fixed on the transmission chain plate. The feeding mechanism comprises a manipulator moving guide rail, a feeding mechanism clamping cylinder and a manipulator drive cylinder. The discharging mechanism comprises a discharging slide groove arranged on the frame and a discharging mechanism drive cylinder. The vacuum-sealing packaging machine has the advantages that a packaging bag can be sealed in one vacuum chamber, efficiency can be improved through synchronic operations of the multiple vacuum chambers, the vacuum chambers are divided into fixed active front chambers and movable passive rear chambers, the vacuum chambers are simple in structures, actions are reliable, vacuum sealing effect is good, production and mounting can be implemented easily, maintenance performance is good, and online detection of product quality can be realized.

Description

technical field [0001] The invention relates to the technical field of design and packaging machinery, and in particular relates to a vacuum packaging machine. Background technique [0002] At present, there are two basic styles of automatic vacuum packaging technology mainly aimed at the form of three-side sealed packaging bags: multi-station bag feeding rotary type and double-station bag feeding alternate type. The typical model is 8-12 jobs. Rotary table type automatic vacuum packaging machine and horizontal bag type vacuum packaging machine. [0003] Its basic working style is: [0004] Multi-station rotary type: The main transmission cycle is realized by using multi-station rotation. Each station completes the processes of automatic bagging, vacuuming, sealing and unloading in the process of one rotation. 8-12 Each station is used to improve work efficiency (each station is a complete vacuum chamber, which is the style of a vacuum chamber sealing a packaging bag). ...

AI Technical Summary

Problems solved by technology

[0005] Existing problems: Using multiple cams and linkages to realize automatic control has the advantages of reliable operation and convenient speed regulation, but it has high requirements for the precision of processing, manufacturing and installation, as well as high requirements for materials. At the same time, it is inconvenient to debug and maintain, and requires high level of relevant personnel

[0007] Existing problems: There are advantages of simple principle and convenient energy transmission

However, the multi-bag automatic holding and arrangement mechanism is adopted inside the vacuum chamber, which has a complex structure, many failure points, high requirements on the use environment, and inconvenient maintenance.

At the same time, the size and quality of the vacuum chamber are large, and the power of the drive system and the vacuum system is large.
