Paper tube precise cutting machine

Abstract

The invention discloses a paper tube precise cutting machine, and belongs to the technical field of cutting equipment. According to the technical scheme, the paper tube precise cutting machine is characterized in that three paper tube bearing rollers which are arranged around the center and are arranged at equal intervals in pairs are used for bearing a paper tube, and the three paper tube bearingrollers synchronously rotate in the same direction so as to drive the paper tube to rotate; a lead screw is arranged among the three paper tube bearing rollers, and a cutting device capable of movingleft and right along the paper tube is arranged on the lead screw; a cutting saw in the cutting device is connected to one end of a telescopic rod, so that the cutting saw slowly moves from the inside to the outside of the paper tube so as to carry out girdling on the rotating paper tube; and the cutting device is driven to move linearly through the rotation of the lead screw, and cutting is carried out again when the cutting device reaches the required size position so as to obtain the paper tube length meeting the requirement. Compared with a traditional mode, the cutting device is arrangedin the bearing rollers so that cutting can be carried out from the inside to the outside of the paper tube, the bearing rollers cannot be touched, and the safety is relatively high; and the cutting saw is deep in cutting, so that the generation of trimming burrs is avoided, and the cutting effect is improved.

Description

Technical field [0001] The invention belongs to the technical field of cutting equipment, and specifically relates to a paper tube precision cutting machine. Background technique [0002] Paper tube finishing machine is a commonly used equipment in the process of paper tube processing. At present, paper tube cores are used in many industries, and these uses are expanding. After the paper tube is rolled, the length of the paper tube will be The paper tube is cut on the tube cutting machine. The paper tube fine cutting machine is a supporting equipment for the slanting machine. Its main purpose is to cut the paper tube twice to achieve customer satisfaction. [0003] There are currently two mainstream models, one is a purely mechanical planetary paper tube finishing machine, and the other is an automatic paper tube finishing machine with servo positioning. The traditional precision cutting machine requires manual adjustment, which is very inconvenient and the positioning accuracy is...
