Paperboard cutting device

Abstract

The invention relates to a paperboard cutting device. By means of the paperboard cutting device, when paperboards of different thicknesses are cut, cutting precision can be guaranteed. The paperboardcutting device comprises a device base, a cutting roll and a paper pressing belt. The paper pressing belt is arranged on a guiding roll in a wound manner and acts on the cutting roll. A feeding opening and a discharging opening are formed between the paper pressing belt and the cutting roll. The paperboard cutting device is characterized in that the two ends of the portion, located at the feedingopening, of the guiding roll are mounted on floating plates in a rotatable manner; each floating plate can slide up and down and is provided with an adjustment window; each adjustment window is internally provided with an eccentric wheel; the upper edge face of each adjustment window is tangent to the upper end point of the corresponding eccentric wheel; and the lower edge face of each adjustmentwindow is tangent to the lower end point of the corresponding eccentric wheel. According to the paperboard cutting device, by means of the structure including a connecting rod and the two eccentric wheels, the floating plates at the left side and the right side can move up and down completely synchronously; thus, the guiding roll mounted on the two floating plates can move up and down in absolutely-horizontal posture; and therefore, it is guaranteed that in the conveying process, the paperboards cannot shift.

Description

technical field [0001] The invention relates to a cardboard processing machine, in particular to a cardboard cutting device. Background technique [0002] Cardboard cutting machine is a kind of equipment for cutting cardboard. As the core mechanism of the cardboard slitting machine, the structure of the cardboard slitting device determines the quality of the cardboard slitting. The cardboard slitting device generally includes a slitting roller, a paper pressing belt and a slitting knife. The paper pressing belt is pressed on the slitting roller through a guide roller, and the slitting knife is located on the rear side of the slitting roller. There is a feed port and a discharge port between them, and the cardboard enters from the feed port. With the rotation of the slitting roller, the paper pressing belt and the slitting roller press the cardboard to turn over, and at the same time, the slitting knife cuts the cardboard. Finally, the cardboard comes out from the discharge...

Problems solved by technology

However, the two springs on the left and right cannot be exactly the same, which causes the pressure of multiple fixed bushings on a guide roller to the cardboard to be different. If the pressure is slightly different, the conveying direction of the cardboard will be shifted. , so that the cutting of the cardboard by the slitting knife will also deviate, resulting in an increase in the scrap rate
