Problems solved by technology

[0005] In 2011, China's utility model patent 201120033012.6 disclosed a fully automatic non-intermittent vacuuming and nitrogen filling production line for sealing tanks: 1. The vacuum nitrogen filling device needs to use two large turntables on the upper and lower coaxial axes to pump and nitrogen, The device only has 8-16 through holes, and needs to be equipped with two chambers, a vacuum chamber and a nitrogen chamber, and the structure is complex; 2. The two chambers of the device are under the turntable, which greatly increases the powder accumulation. risk, which is not conducive to the convenience and convenience of usual maintenance; and the cavity is designed under the turntable, which requires a large force to press it tightly to ensure the seal; 3. The sealing cylinder of the device moves up and down along the shaft of the supporting tank, and the sealing cylinder and the shaft of the supporting tank The sealing ring is sealed between them, and the up and down movement of the sealing cylinder reduces the service life of the sealing ring; 4. There are strip windows on the side walls of the vacuum chamber and the nitrogen filling chamber of the device, which means that the chamber must be turned to a specific position. The specific angle area can complete specific vacuuming or nitrogen filling action, low flexibility
[0006] Existing vacuuming, nitrogen filling and sealing devices have high residual oxygen content, the tank body has the risk of being filled with air again, the device is prone to powder accumulation, the negative pressure rate cannot be adjusted, the amount of powder leakage is high, and the loss is high

Abstract

The invention relates to the technical field of food packaging, in particular to a high-speed vacuumizing and protective gas filling can sealing production line. The production line comprises a high-speed can pre-sealing machine, a high-speed vacuumizing and protective gas filling device and a high-speed solid can sealing machine which are connected through a conveying chain. The high-speed can pre-sealing machine is provided with a can sealing rack, a driving rotation mechanism, a pressing wheel transmission mechanism, a lifting mechanism, a can feeding mechanism, a can cover conveying drive mechanism, a cover discharging mechanism, a cover falling mechanism, a can hoisting and lifting mechanism, a pressing head mechanism, a can discharging mechanism and a drive mechanism. The production line is compact in structure, small in occupied area, high in can sealing and vacuumizing efficiency and capable of meeting the requirement of modern high-speed production. The can pre-sealing machine and the solid can sealing machine only need one motor to drive the driving rotation mechanism so as to drive the whole device to operate together. The production line can adapt to various can heights. The height is adjusted, and the vertical movement of a pressing head part and a pressing wheel rotating part can be completed through the forward and reverse rotation of a lifting motor, so that the distance between a can hoisting and lifting platform and a pressing head and a pressing wheel is adjusted. And manual adjustment is reduced to the greatest extent.

Description

technical field [0001] The invention relates to the technical field of food packaging, in particular to a high-speed vacuum filling and sealing can production line. Background technique [0002] In terms of food packaging, people are particularly concerned about the freshness of food. For food packaging, there must be a process of vacuuming and filling protective gas and packaging technology, so as to reduce the amount of residual oxygen and the shelf life of products. [0003] The existing vacuum-pumping, nitrogen-filling and sealing machines have limited canning capacity, low work efficiency, and easy to fly powder, which can no longer meet the requirements of high-speed production lines; [0004] The existing equipment for vacuuming and filling protective gas adopts a box body, arranges cans that have been pre-sealed in an orderly manner in the box body, concentrates vacuuming and filling the protective gas, and then flows into a simple sealing process. There will be a w...
