Full-automatic wrapping vacuum packaging machine

Abstract

The invention relates to a full-automatic wrapping vacuum packaging machine, comprising a conveying mechanism for substances to be packaged, an adhesive film distribution mechanism, a vacuum treatment mechanism and a finished-product output mechanism, wherein the conveying mechanism for the substances to be packaged comprises an emptying area A and an emptying area B; the adhesive film distribution mechanism is arranged between the emptying area A and the emptying area B, and comprises an upper packaging and distributing mechanism, a lower packaging and distributing mechanism and a sealing-cutting mechanism; the sealing-cutting mechanism comprises an upper sealing-cutting die and a lower sealing-cutting die which are driven by a power mechanism, and the upper sealing-cutting die is combined with the lower sealing-cutting die for cutting off and binding an upper adhesive film and a lower adhesive film which are used for coating the substances to be packaged; and the vacuum treatment mechanism comprises a conveying belt and a heating and binding mechanism. The vacuum packaging machine provided by the invention can perform vacuum package by utilizing at least three methods, thus the vacuum packaging machine can be used in diversified modes, and the scope of application is quite wide.

Description

technical field [0001] The invention relates to a packaging device, in particular to a fully automatic wrapping vacuum packaging machine and a packaging method thereof. Background technique [0002] The current packaging technology can be divided into two categories: commercial packaging and industrial packaging. The products targeted by the two are different. Among them, commercial packaging is mostly used for light industrial products, and retailers directly deliver product packaging purchased by consumers, such as various food , beverages, daily necessities, etc., while industrial packaging is aimed at the packaging of intermediary products between factories, such as delivery of plastic containers to food manufacturers, delivery of cloth to clothing factories, etc., but such as printed circuit boards, PP prepregs For industrial packaging of electronic products such as copper clad laminates and copper surface substrates, vacuum packaging must be anti-friction, moisture-pro...

AI Technical Summary

Problems solved by technology

However, shrink packaging must be made into bags according to individual product specifications, sealed in bags, and air holes must be made to squeeze out the air in the bags during heat shrinkage, so as to achieve the shrinkage effect of tightly fitting packaging, and because of the use of shrink film, it is moisture-proof And the anti-oxidation effect is limited, and the packaging process is relatively complicated, so only manufacturers of products with small output are using this method

[0005] 3. Bubble cloth, body-fitting protection packaging, because the product is placed on the bubble cloth as the base, the upper layer of film is heated and softened, and then covered on the product, and bonded with vacuum adsorption to achieve body-fitting protection. This method is not expensive because of its low cost. And it can be placed in large and small plates, and then divided into containers after packaging. At present, it is widely used in the industry, and semi-automatic and automatic large-scale packaging machines have been developed, and the market has responded well; however, this method still has many shortcomings. Skin packaging for low-level use. Although it is bonded instantly by vacuuming, it is not vacuum packaging, and the skin adhesive film still has a very high air permeability, which cannot achieve the effect of blocking the outside world.

[0006] 4. Vacuum packaging. In order to obtain better storage life and moisture-proof and anti-oxidation effects of products, such as packaging of high-level linear circuit boards and electronic products has been gradually replaced by high-cost food vacuum packaging in recent years; currently used The most popular vacuum packaging is still the most common vacuum packaging machine for ordinary food. Although the food packaging method can achieve the protective effect of vacuum packaging, its biggest disadvantage is that prefabricated vacuum bags must be used, and the packaged products are easy. Skew, and often over-vacuum pumping during packaging, resulting in air leakage due to damage to the vacuum bag when the vacuum product is packed or transported to the user, and the product is returned in batches and the cost is suddenly increased
