[0004] At present, there are two methods of creasing the traditional bottom of the square bottom paper bag machine: 1. The creasing bottom roller is a rubber roller. Because the rubber is soft, the creasing effect is not ideal and it is easy to be damaged; 2. The creasing bottom roller is a grooved steel roller. Roller, every time a specification is replaced, the grooved steel roller must be replaced, and the indentation specification is calculated in multiples of 5 and 10, the bag-making specification has limitations, low efficiency, and high cost

The invention discloses an adjusting device of a bottom roller for creasing the bottom of a paper bag machine. A bottom roller adjusting sleeve is sleeved on a bottom roller shaft, the bottom roller adjusting sleeve is provided with an opening hole, a bottom roller fixing plate is positioned at the opening hole of the bottom roller adjusting sleeve and is fixed on the bottom roller shaft, the bottom roller fixing plate is provided with a notch groove, an adjusting handwheel is fixedly connected with one end of the bottom roller adjusting sleeve, and the bottom roller shaft and the bottom roller adjusting sleeve are fixed by a locking mechanism; a compression roller adjusting sleeve is sleeved on a compression roller shaft and is provided with an opening, and a creasing knife is positioned at the opening of the compression roller adjusting sleeve and fixed on the compression roller shaft through a creasing knife fixing holder; and gears which are mutually meshed are arranged on the compression roller shaft and the bottom roller shaft, and gears which are mutually meshed are arranged on the compression roller adjusting sleeve and the bottom roller adjusting sleeve. According to the adjusting device disclosed by the invention, the bottom roller does not need to be replaced when the specification of paper bags is changed, and the advantages of reducing the cost, accelerating the adjusting speed and being ideal in creasing effect and long in service life are realized.
Description
technical field [0001] The invention relates to a packaging bag manufacturing machine, in particular to a device for adjusting a bottom roller for realizing creasing at the bottom of a paper bag during the paper bag making process. Background technique [0002] Due to the requirements of environmental protection, the use of plastic bags is limited, and paper bags are widely used in the outer packaging of commodities and people's daily life because of their environmental protection, aesthetics, and convenience of carrying. When making paper bags automatically, it is necessary to realize the bottom forming of paper bags through creasing. The crease realization device includes a bottom roller and a pressure roller. The bottom roller is used to drive the movement of the base paper. There is an indentation knife on the pressure roller. Through the relative rotation of the pressure roller and the bottom roller, the creasing knife is placed at the desired position. Compress the ba...
