Description

Technical Field

[0001] The invention relates to the field of packaging machines, in particular to an automatic coding packaging machine. Background Art

[0002] Packaging machines are mechanical equipment used to package products. They usually integrate multiple functions, such as metering, filling, sealing, labeling, coding, etc., to meet the packaging needs of different products. Packaging machines are widely used in various industries such as food, medicine, chemical industry, daily chemicals, electronics, etc., and are an indispensable and important equipment in modern production.

[0003] The main functions of packaging machines include: Protecting products: Packaging machines wrap products with packaging materials (such as plastic bags, cartons, cans, etc.), which can effectively prevent products from being contaminated, damaged or deteriorated during transportation and storage. This is of great significance for maintaining product quality and extending product shelf life. Convenient storage and transportation: Packaged products are easier to stack, store and transport, which can save space, improve transportation efficiency and reduce logistics costs. Promote sales: Exquisite packaging can attract consumers' attention and improve the market competitiveness of products. Product information, brand logos, promotional information, etc. can also be printed on the packaging to help consumers better understand the product and stimulate the desire to buy. Realize product traceability and anti-counterfeiting: Modern packaging machines are usually equipped with coding, printing and other devices, which can print production date, batch number, anti-counterfeiting code and other information on the packaging. This information helps to achieve product traceability and ensure product quality and safety; at the same time, the anti-counterfeiting code can also effectively combat counterfeit and shoddy products and protect the rights and interests of consumers. Improve production efficiency: Automated and intelligent packaging machines can greatly improve production efficiency, reduce manual operations and reduce production costs. They usually have high-speed, precise and stable working performance, and can meet the needs of large-scale production.

[0004] However, when the existing technology is actually used, in the field of modern industrial production and commodity circulation, packaging, as the "outer coat" of the product, not only plays a role in protecting the product, but also carries the important mission of transmitting product information. With the continuous expansion of the market scale, enterprises have increasing requirements for packaging efficiency, coding accuracy and automation. Traditional manual packaging and coding methods consume a lot of manpower and are prone to coding errors, irregular packaging and other problems, making it difficult to meet large-scale, high-quality production needs.

[0030] When in use, the material to be packaged is transported to the inside of the feed hopper 101. When the material is transported to the inside of the feed hopper 101, the material will be discharged downward into the inside of the distribution channel 102 through the feed hopper 101. When the material is discharged into the inside of the distribution channel 102, the material will be guided and distributed by the distribution plate 105, so that the material enters one of the distribution bins 106. When the material enters the inside of the distribution bin 106, the material will be blocked by the opening and closing plate 107, so that the material gradually accumulates in the distribution bin 106. When the material gradually accumulates to a certain height in the distribution bin 106, the full position of the material will be sensed by the material level sensor 111. When the material level sensor 111 senses that the material has reached the full position, the first drive motor 1 is turned on by control. 03. When the first driving motor 103 is turned on, it will drive the swing shaft 104 to rotate. When the swing shaft 104 rotates, it will drive the dividing plate 105 to swing. When the dividing plate 105 swings, it will guide the materials in the dividing channel 102 to the inside of another dividing bin 106. At the same time, when the materials in the dividing bin 106 reach full, the first electric telescopic rod 110 is opened by control. When the first electric telescopic rod 110 is opened, the second connecting rod 109 cooperates with the first connecting rod 108 to drive the opening and closing plate 107 to swing downward and open. When the opening and closing plate 107 swings downward and opens, the materials accumulated in the dividing bin 106 will be discharged downward into the lower hopper 112, thereby achieving the function of dividing the materials to be packaged;

[0031] When the material accumulated in the sub-bin 106 is discharged into the lower hopper 112, the packaging bag is placed on the upper end of the conveyor line 2, and the upper opening of the packaging bag is aligned with the flexible discharge port 113. When the upper opening of the packaging bag is aligned with the flexible discharge port 113, the second electric telescopic rod 116 is controlled to open. When the second electric telescopic rod 116 is opened, it will drive the swing frame 114 to swing. When the swing frame 114 swings, it will drive the pressing bar 115 to release the pressing and closing aligned with the flexible discharge port 113. When the pressing and closing aligned with the flexible discharge port 113 is released, the material in the lower hopper 112 will be discharged into the packaging through the quasi-flexible discharge port 113. Inside the bag, when the material is discharged into the packaging bag, the conveyor line 2 is controlled to be opened. When the conveyor line 2 is opened, the packaging bag containing the material will be conveyed forward. When the packaging bag containing the material is conveyed forward, the upper opening of the packaging bag will be guided to the sealing machine 207 through the guide groove 208, so that the sealing machine 207 can perform a sealing operation on the packaging bag conveyed forward. After the sealing machine 207 seals the packaging bag, the packaging bag will be automatically conveyed backward. When the packaging bag is automatically conveyed backward, the sealed packaging bag will be sprayed with code by the inkjet gun 211, so as to realize the material separation and facilitate the inkjet operation of sealing the packaging bag containing the material;

[0032] At the same time, by controlling to start the second drive motor 203, when the second drive motor 203 is turned on, the transmission screw 204 will be driven to rotate through the synchronous wheel and the synchronous belt transmission. When the transmission screw 204 rotates, the lifting seat 205 will be driven to move up and down linearly through the screw nut transmission. When the lifting seat 205 moves up and down linearly, it will synchronously drive the sealing machine 207 and the inkjet gun 211 to adjust the height up and down, so as to facilitate the sealing and inkjet coding operations on packaging bags of different heights. By controlling to start the third drive motor 209, when the third drive motor 209 is turned on, the swing rod 210 will be driven to swing through the synchronous wheel and the synchronous belt transmission. When the swing rod 210 swings, it will drive the inkjet gun 211 to swing and adjust, so as to facilitate the sealing and inkjet coding operations on packaging bags of different heights, and at the same time, the inkjet coding angle of the packaging bag can be swung to adjust.
