Roller-type fed material bagging machine

Abstract

The invention discloses a roller-type fed material bagging machine which is provided with a rack and a roller. A bag feeding device and a heat sealing device are arranged on the outer side of the roller. Work grooves are evenly formed in the rollers. A bag propping mechanism is arranged at a feeding position of a material bagging machine and is provided with a bag propping frame. U-shaped bag propping rods are arranged on the two sides of the bag propping frame. Bag opening mechanisms are arranged at the work grooves. The roller-type fed material bagging machine is characterized in that packaging bag tensioning mechanisms are arranged on one sides of the U-shaped bag propping rods; a bag rubbing mechanism is arranged above the work grooves; and bag grabbing and pulling mechanisms are arranged at discharge outlets of the work grooves. By adoption of the bagging machine, tensioning of a bag opening during material feeding of a packaging bag is achieved, tilting-up or wrinkling of the two edges of the packaging bag is avoided, the two walls of the packaging bag can be rubbed open when the bag needs to be opened, and the bag opening effect is guaranteed; and before heat sealing, the bag opening of the packaging bag is pulled to be level, so that the bag opening after heat sealing is flat, and a good packaging effect is achieved.

Description

technical field [0001] The invention relates to a packaging machine, in particular to a drum-type feeding bagging machine. Background technique [0002] For food packaging, automatic packaging is currently used. This automatic packaging is to automatically feed the packaging bag. After the packaging bag is opened, the packaging bag is filled with food. For some puffed and wafer foods, such as biscuits, candies, etc., these foods are generally packaged in small packaging bags, and then need to be packed into large packaging bags according to a certain amount. This process is called bagging process. The applicant has just applied for a patent named a drum-type feeding bagging machine, the patent notification number is CN103029868B, which specifically discloses the following content: a drum-type feeding bagging machine has a drum, and the The outer side of the drum is equipped with a bag feeding device and a heat sealing device, which is characterized in that there are working...

Problems solved by technology

However, the large packaging bag is filled with small packaging bags of food. After the large packaging is taken out, the mouth of the bag is in an open state. If it is heat-sealed with a heat-sealing device immediately, the mouth of the bag will become wrinkled and the bag wall will be dislocated. Therefore, its heat sealing effect is not very ideal
