Electric control system of full-automatic vacuum packaging machine

Abstract

The invention relates to an electric control system of a full-automatic vacuum packaging machine. The vacuum packaging machine comprises a host machine, a blanking device and a vacuum sealing device, wherein the host machine comprises a printing device, a membrane releasing device, a sealing block temperature control device, a bag traction device and a bag opening device; the blanking device comprises an blanking measuring disc, a punching head and a servo motor screw rod; the vacuum sealing device comprises a main box, a rotary valve and a servo motor ball screw; and the two side surfaces of the main box are provided with bag receiving devices, bag conveying devices, conveyer belts and sealing devices. The electric control system comprises a programmable logic controller (PLC) body, a host machine control subsystem connected with the PLC body, and a blanking control subsystem and a vacuum sealing control subsystem which are connected with the PLC body. The electric control system realizes completely automatic detection production, effectively improves packaging efficiency and product quality and saves labor cost.

Description

technical field [0001] The invention relates to an electrical control system of a fully automatic vacuum packaging machine. Background technique [0002] Vacuum packaging machine is widely used in packaging food. This kind of packaging machine can prevent the product from oxidative mildew, anti-corrosion and moisture-proof, and can guarantee the quality, freshness and prolong the storage period of the product. In addition, the vacuum packaging machine will automatically seal the packaging bag after it is evacuated into a low vacuum. Due to the high degree of vacuum in the bag, there is very little residual air, which inhibits the reproduction of bacteria and other microorganisms, and avoids the oxidation, mildew and corruption of items. Some soft items, after being packed by a fully automatic vacuum packaging machine, can reduce the packaging volume and facilitate transportation and storage. [0003] At present, the vacuum packaging machines in the domestic market are all s...

AI Technical Summary

Problems solved by technology

[0003] At present, the vacuum packaging machines in the domestic market are all semi-automatic, and need to be manually put into the bag, and then vacuumized and sealed. The operation requires more manpower, so the work efficiency is low, and it is difficult to ensure that the manual operation meets the hygienic requirements.

Recently, Japan and South Korea have developed an automatic vacuum packaging machine. Although automatic bag feeding is realized, each bag is vacuumed and sealed, so the packaging speed is slow and the efficiency is low.
