Particle shaping vacuum packing machine

Abstract

The invention discloses a particle shaping vacuum packing machine and belongs to the technical field of packing machines. The particle shaping vacuum packing machine comprises a packing body with a vacuum chamber, a packing bag is placed inside the vacuum chamber, the packing body is internally provided with a plurality of air bags used for performing vacuum packing on the packing bag, the vacuumchamber finishes vacuum pumping through an electromagnetic valve and a vacuum pump which are arranged inside the packing body, after vacuum pumping of the packing bag is finished through the vacuum pump, sealing of the packing bag is performed through a sealing device, the sealed packing bag is moved through a moving device, shaping and pressing are performed on the packing bag obtained after vacuum pumping and sealing through a pressing and shaping device, and air is pumped after pressing is finished. According to the particle shaping vacuum packing machine, an upward pushing air cylinder anda side pulling air cylinder are replaced through the air bags, shaping can be successfulat a time, the periphery of the packing bag is molded more rounded and is not prone to being damaged, noise isreduced, the packing rate is increased, the air bags are not prone to being affected by residues, the failure rate is lower, the service life is prolonged, and the air bags are easy to assemble and replace, the process is simplified, an external-connection air source is not needed, and the service condition is reduced.

Description

technical field [0001] The invention relates to a vacuum packaging machine, in particular to a particle shaping vacuum packaging machine, which belongs to the technical field of packaging machines. Background technique [0002] With the development of social economy and scientific level, the public is more and more fond of vacuum packaging with guaranteed quality and durability, and supermarkets or large warehouses, which are gathering places for mass consumption, have higher and higher requirements for the shape of vacuum packaging: flat The brick-shaped products are not only beautiful and generous, which is conducive to improving the grade of products, but also convenient for storage and transportation. [0003] At present, the common solution is: the particle shaping packaging machine needs to use a cuboid opening mold: first put the packaging bag into the cuboid mold properly, then pour the packaged items into the bag, and then put the mold into the vacuum cavity Inside...

AI Technical Summary

Problems solved by technology

[0006] 3. Because of the mold shape of the rectangular parallelepiped at the bottom, the plastic bag makes the lower part of the packaged product close to a prismatic shape, and the edge is too sharp, which is easy to be cut during transportation, which is not conducive to the transportation and storage of the bag

[0012] Through such operation, the particle shaping packaging machine with pneumatic vibration structure solves the problems of long working hours, unevenness and angularity of the traditional packaging machine with the help of molds. However, the technical solution still has the following shortcomings:

[0013] 1. The use of a vibrating machine can make the packaging bag flat and full around, but the noise is too loud, which deteriorates the packaging environment and limits its use.

[0014] 2. The cylinder structure is adopted. If it is not cleaned after long-term use, the fallen materials will be stuck in the gap, which will cause malfunctions in operation and a high failure rate.

[0015] 3. Compared with the traditional vacuum packaging machine, the pneumatic vibration structure is complicated, the production is cumbersome, the cost is high, and the maintenance is troublesome. Professionals are required to repair and replace related parts

[0016] 4. The pneumatic structure needs an external air source, and the external air source needs to use an air compressor, and the air compressor will also produce noise, which further limits its use place

[0017] The above disadvantages make the plastic packaging machine with this structure noisy, need an external air source, high failure rate, difficult to maintain and repair, high cost, and cumbersome process, which is not conducive to widespread promotion and use
