Vacuum packaging machine and operation method thereof

Abstract

The invention discloses a vacuum packaging machine and an operation method thereof. The vacuum packaging machine structurally comprises a feeding sliding groove, a supporting frame sealing machine groove, a slag particle sorting groove, a particle discharging nozzle, a carrying plate, a man-machine interface box, a bag containing box groove and a power distribution base. The supporting frame sealing machine groove is used for being matched with the bag containing box groove, the operation of sucking gas such as internal oxygen on the single side of a packaging pressing joint strip is formed, the effect of preventing deterioration by injecting trace nitrogen into the sealed end of a thin-diameter needle body is achieved after plastic particles roll into a bag, then the sealed position, prone to protruding, abutting against and loosening, at the single side end is subjected to compaction and embedding of a sealing strip pressing clamping frame, the airtightness of a whole colloid thin strip groove is guaranteed, after the particles are attached to the air-exhausted wizened bag body, fine gap liberation shaking under the action of trace nitrogen is achieved without losing the tightness, the protruding mass of the particles one by one is formed, the variable mass and the waste amount are reduced to a great extent, and the air tightness of the protrusions at the corners of the bag opening sealing strip of PVC plastic particle vacuum packaging is enhanced.

Description

[0001] This application is a divisional application with the application date of August 14, 2019 and the application number CN201910748839.6. The title of the invention is a vacuum packaging machine with one-sided sliding suction of sealing pads packed in PVC plastic particle bags. technical field [0002] The invention relates to a vacuum packaging machine and an operation method thereof, which belong to the field of equipment for producing plastic granules. Background technique [0003] PVC plastic granules are a kind of polymer material technology with a wide range of applications. They can be used in building materials and auxiliary materials, and can also be used in teaching toys. The deliquescence and oxidation when standing for a long time, the stability of the quality of packaging plastic particles for a long time, and the shortcomings of the current technology that need to be optimized are: [0004] Since PVC plastic particles are easily oxidized by deliquescence, t...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a vacuum packaging machine and its operation method to solve the problem that since PVC plastic particles are easily deliquescent and oxidized, storage requires a dry internal environment with anaerobic vacuum and nitrogen supplementation for maintenance. products, but often the plastic granules in the bagging process will indirectly absorb moisture due to the reason of sealing, and the humidity of the external environment air will leak into oxygen and water vapor due to the thick strips on the left and right sides of the sealing. Vacuum-packed granules have poor texture and adhesion, and the interior is generally fluffy and there are too many gaps without a sense of firmness, so that the interference factors in the later stage of granule packaging cannot be avoided, resulting in the influence of low humidity pressure to deteriorate the PVC plastic granules, which affects the texture of the later use effect Loose and softening situation, waste of packaging cost
