TH10044A - Sheet material winding machine with improved cutting mechanism - Google Patents

Abstract

Improvements in sheet rollers with perforated rollers and a combination of rollers and shearing rollers that are assembled with a set of cutting blades, in which some cutting blades are mounted on the main and blade rollers. Some cutting blades are mounted on the cutting roller. And the moving sheet material is sent from the unfolded main roll and rolled into the product roll, for example A roll of toilet paper or a toilet paper roll with several sub-sheets The improved split discs include parallel-moving cutting blades that can be installed closer together than traditional artisanal cutting blades. Therefore, the elongation of the sheet material is greater, making the sheet material more reliable. And the cutting blade is installed to work with the length of the sheet material moving along the roll, the sheet material can be longer than the traditional winder to enable the cutting to end the roll by cutting along. The perforation lines are transverse rather than tearing the disheveled sheet material across. The installation of such cutting blades makes the working range The perforation lines in the moving sheet material are widened during the termination of the roll. The perforation relationship between the cutting mechanism and the moving sheet material is easier to maintain a wider operating range at all times while the other elements are constant.This fabrication is especially useful for Sheet material, such as wrinkled paper, must be strongly clamped in the direction of the winder before the wrinkled paper is cut along weak cross-lines, such as intermittent or perforated lines.

Claims (7)

1.Improved slitting mechanism in mechanical type sheet roll forming machine for unrolling the main roll of material and passing the sheet material through the sheet roll forming machine There is a mechanism for easily tearing perforation lines in sheet materials at the length of the substrate in accordance with the direction of roll forming machine. Cutting mechanism for cutting the sheet material along the perforation lines at the length of the roll. And there is a mechanism for winding sheet material with the same length as the product rolls into product rolls. And which the cutting mechanism consists of the main roller, the cutting roller, the mechanism for rotating the main roller and the cutter roller in relative timing. And there is a set of cutting blades in which some cutting blades are mounted on the main roller and some are mounted on the cutting roller and these cutting blades move the rotators in and out of the Grind each other without touching each other by the rotation of the main roller and the dedicated cutting roller, but in cutting the sheet material to the end of roll The enhancements include a mechanism for keeping the cutter blades in parallel and at the same speed as the blades move in and out of the grind without contact. 2.
