[Chinese Packaging Network News] In simple terms, the packaging machine is the product packaging machine, play a protective, aesthetic role. In the process of packaging and processing, products are generally sent to the metering device for measurement by means of a feeding device on the packaging machine, and then filled into the packaging container, and packaged and packaged. What are the common packaging machines?
Packaging machines commonly used feeding devices, metering devices, packaging containers and packaging material supply device, filling and filling device and wrapping packaging device.
First, supply device for packaged goods
The function of the supply device of the packaged goods is to supply the articles to be packaged stored in the hopper to the article metering device according to the requirements of the packaging process for measurement, and then the other devices of the packaging machine are used for the packaging. The supply device for packaged goods is generally composed of a hopper, a feeding channel, a feeder, a blocking prevention device, a selection-to-arrangement device, and a driving device. Due to the physical and chemical properties of the articles, the natural form and the packaging process requirements, the supply device has a variety of structural forms. According to the driving mode of the supply items, the supply device can be divided into a gravity feeding device, a chain (belt) conveying device, an auger conveying device, a 9 conveying device, a rotary table conveying device, and a vibration feeding device. The feeding and packing basin should be simple in structure, reliable in operation, and adapt to the material properties of the materials to be delivered, and be consistent with the subsequent packaging process operations.
Second, a measuring device for packaged goods
In order to facilitate the sale and use of products, and to facilitate the automation of packaging operations, a product must be quantitatively measured prior to packaging. On the packaging machine, the measurement of the goods is an important operation of the packaging operation. The correct design of the metering device and the rational selection of the metering parameters enable accurate, rapid and economical metering operations. According to the physical and chemical properties of the goods, natural form, packaging specifications and sales and usage habits, different measurement methods need to be used. For items with regular shapes, such as blocks, rods, and stems, they are often counted using the counting method. For bulky particles, powders, liquids, and viscous substances, constant volume methods are used for the measurement; The aggregated granules, powdered articles and irregular shaped bulky articles are often weighed and packaged.
Third, supply devices for packaging containers and packaging materials
On the packaging machine, the packaged goods and the packaging container or the wrapping material are respectively sent by the feeding device to the filling or wrapping station, and the packaging operation is completed by the filling or wrapping device. The packaging device and the packaging material supply device vary depending on the quality, shape, and condition of the packaging container and the wrapping material. For rigid, semi-rigid containers, such as cylinders, bottles, boxes, boxes and other rigid, often used chain, belt conveyor or conveyor raceway, the transmission speed is generally -0.6-0.8M/S; Flexible packaging containers and single-sheet I reel paper, reel film and other wrapping materials are often provided by belt conveyors, A-type feeders, lifters, and vacuum suction nozzles. give away.
Fourth, filling and filling device for packaging materials
The filling and filling of the packaged product refers to discharging the riveted product after the halo is fixed and guiding the loading operation into the packaging container. Depending on the characteristics of the item, different filling and filling devices are required. Filling and filling devices commonly used according to the filling and filling methods can be divided into gravity filling and filling type, vacuum filling and filling type, pressure forced filling and filling type, push loading type and robot pick and place type. In automatic packaging machines, metering devices and filling and filling devices are often coupled to each other. Sometimes, the dosing device doubles as a filling and filling device. Some devices do quantitative measurement during the filling and infusion process. Therefore, when designing a metering device, it should take into account how the measured material is discharged and guided to the filling and filling device for filling operations. Filling and filling operations can be divided into operations such as bagging, loading, boxing and bottling according to the different packaging containers used.
Section 5 Packaging Devices for Packaging Items
The package of an article package refers to the package sealing operation of a container filled with packaged articles or the wrapping and sealing operation of a packaged material sheet that has taken over the articles so as to meet the packaging requirements. The packaging operation of the goods packaging shall ensure the protection of the articles, that is, during the specified period of safe use, the articles shall not be deteriorated due to unsatisfactory packaging operations; or the goods shall be damaged due to poor package quality during storage, sales, and display. .
Packaging devices for packaging of goods can be divided into two types according to packaging methods: sealing devices for filling containers and sealing devices for packaging materials. What kind of process means and packaging materials are used to seal the container and the package are used to determine the physical and chemical properties of the packaged goods, containers, and wrapping materials. Such as soap, perfumes require fragrant; 1 canned foods require preservation; dissolved gas drinks require airtight; glass type brittle and rigid containers should not be subjected to rigid impact: paper packaging materials easy to tear; plastic packaging materials, easy plastic deformation Wait. A comprehensive analysis should be conducted on various specific packaging conditions to select the best packaging process and packaging materials, and to select the ideal packaging device accordingly.
