What are the commonly used devices for packaging machines?
Commonly used packaging machines include feeding devices, metering devices, packaging containers and packaging material supply devices, filling and filling devices, and wrapping and packaging devices.
1. Supply device for packaged articles
The feeding device of the packaged article has the function of feeding the articles to be packaged stored in the hopper to the article measuring device according to the packaging process requirements, and then performing the packaging by other devices of the packaging machine. The feeding device for the packaged articles is generally provided by the hopper. The utility model comprises a conveying channel, a feeding device, an anti-blocking device, a sub-selecting alignment device and a driving device. Since the physicochemical properties, natural forms and packaging process requirements of the articles vary widely, the supply device has various structural forms. According to the driving method of the articles to be delivered, the feeding device can be divided into a gravity feeding device, a chain (belt) conveying device, a screw conveying device, a 9-feed device, a turntable channel conveying device, a vibration feeding device, etc. The structure should be simple, reliable, adapt to the material characteristics of the material to be delivered, and coordinate with the subsequent packaging process operations.
2, the metering device for packaging articles
In order to facilitate the sale and use of the products, and to facilitate the automation of packaging operations, 1 life needs to be quantitatively measured before packaging. On the packaging machine, the measurement of items is an important process of packaging operations. Proper design of the metering device and reasonable selection of the metering parameters can make the metering operation accurate, fast and economical. According to the physical and chemical properties, natural form, packaging specifications and sales and usage habits of the articles, different measurement methods are required. For articles with regular shapes, such as blocks, rods, and stem-shaped articles, the counting method is often used for measuring packaging; for loose glumes, powdery articles, liquids, and viscous materials, the volumetric packaging is often used for measurement; 1. The granules, powdered articles and irregular shaped block articles are often packed by weighing method.
3, the packaging container and packaging material supply device
On the packaging machine, the packaged item and the packaging container or the wrapping material are respectively sent to the filling or wrapping station by the feeding device, and the packaging operation is completed by the filling or wrapping device. The feeding device of the packaging container and the packaging material is wrapped with the packaging container and the wrapping device. The quality, shape and state of the package materials are different. For rigid and semi-rigid containers with large rigidity such as barrel, tender, bottle, box and box, chain, belt conveyor or conveyor track is often used. The conveying speed is generally -0.6-0. 8M/S; belt conveyors, A-type supply devices, etc. are often used for wrapping flexible packaging containers and single-sheet I reel paper, reel film and the like. 1. Each material delivery device and vacuum suction device are used for feeding.
4. Filling and filling device for packaging materials
The filling and filling of the packaged articles refers to the charging operation of discharging the rivets after the fixed halo is smeared and guiding the loading into the packaging container. Depending on the characteristics of the item, different filling and filling devices are required. Commonly used filling and filling devices can be divided into gravity filling and filling type, vacuum filling and filling type, pressurized forced filling and filling type, push loading type and robot pick-and-place type according to different filling and filling methods. In automatic packaging machines, the metering device and the filling device are often coupled to each other. Sometimes, the dosing device doubles as a filling and infusing device, and some devices achieve quantitative metering during the filling and infusion process. Therefore, when designing the metering device, it is necessary to consider how the metered material is discharged and guided to the filling infusion device for filling operation. Filling and filling operations can be divided into bagging, boxing, boxing and bottling depending on the packaging container used.
5. Packaging device for article packaging
The packaging of the package of the article refers to the packaging and sealing operation of the container filled with the packaged article or the wrapping and sealing operation of the packaging material piece that has received the article, thereby achieving the packaging requirement. The packaging operation of the article packaging must be ensured The protection of the articles, that is, during the specified safe use period, the articles are not deteriorated due to the unqualified packaging operations; or the articles are damaged due to poor packaging quality during storage, transportation and display.
