The standard of can sealing machine
This standard specifies the product classification, technical requirements, test methods, inspection rules and signs, packaging, transportation, and storage of can sealing machines. This standard applies to automatic and semi-automatic can sealing machines for rolling food and daily chemical metal cans. Glass jar sealing machine can also be used as a reference.
Application range of sealing machine
Can sealing machine It is mainly used in the sealing of cans, iron cans and paper cans. It is used in general pharmaceutical, daily chemical, food, beverage, chemical and other industries.
Semi-automatic sealing machine is often used as a stand-alone machine or matched with small batch and multi-variety filling lines.
Fully automatic sealing machine is a production line for multiple and large batches of single products. According to the different materials, the front process of the automatic filling machine is often equipped with a fluid filling machine, a powder filling machine, etc. The post-process is often matched with labeling machines, inkjet printers and other equipment.
Production line process
The packaging process of canned beer is simpler and easier to control than bottled and barreled. The main equipment of an automated canning line consists of a depalletizer, a canned wine-roll sealing machine, a sterilization machine, a cartoner/sealer, and the filling speed can reach 1000cpm, which is comparable to the canning machine of Tingzi Factory.
The process of beer canning is as follows: the can sealer unloads the layered empty cans from the plastic tray, pushes them onto the plastic chain plate, enters the washing machine, rinses with 80oc hot water, and dries them to achieve sterility. Then use co2 isobaric filling, use carbon dioxide to replace the air in the tank, after filling, spray carbon dioxide to the mouth of the tank and quickly seal the lid. Use an automatic quantitative meter to detect the liquid level, followed by pasteurization (spray sterilization). The filled tins are dried by an air dryer, and then the production time is sprayed on the bottom of the tank by the inkjet printer.
According to the packaging form, different packing machines are used: the single-chip die-cut cardboard is a wrapping type, the tin is pressed onto one large surface of the cardboard, and the mechanical rod lifts the other large surface and two sides in turn, and heats The sol quickly bonds the manufacturer's seams and flaps. Wrapped type is widely used in domestic breweries and is provided by German Kisters company. There is also a kind of knockdown (formed boxes glued by the manufacturer in the carton factory). The suction cup of the box packer sucks the large surface into a hollow, and the mechanical rod pushes the listener inward and then glues it. This packing method is efficient Very high, widely used abroad. Wrapping type cartoning machine can also pack thermoplastic film tins with paper trays. This fashion cartoning machine needs to be equipped with a set of pe film slitting, wrapping system and heat shrinking furnace.
If there is printing on the surface of the pe film, a photoelectric eye device is required. After automatic packing and bonding, the listening box generally no longer uses opp sealing tape. A typical 355ml can is 24 cans, and 18 and 12 cans are also available, depending on the consumer's habit of buying the whole box. Modern beer technology widely uses computer identification systems and digital display instruments to assist mechanized filling operations to ensure that the quality of beer is not affected during the filling process. The can sealing machine can automatically detect the following cans manufacturing defects: oil, liquid, deformation, foreign matter, and peculiar smell, and reject unqualified containers from the line.
