Paper tube cutting machine

Abstract

The invention discloses a paper tube cutting machine which comprises a driving unit and a cutting unit. The driving unit comprises a motor and an air cylinder. The air cylinder is connected with the cutting unit. The cutting unit specifically comprises round blades arranged on a cutting shaft in a sleeved mode, and a shell arranged above the blades. One side of the cutting shaft is provided with a bearing which is connected with an air cylinder, the rotation angle of the bearing is controlled through the air cylinder, and therefore the position of the cutting shaft is controlled. A rotation shaft is arranged below the blades, and the diameters of the two ends of the rotation shaft are large. The middle of the rotation shaft is sleeved with a rubber sleeve, and the rotation shaft is connected with a motor. In the machining process, a paper tube is arranged on the rotation shaft in a sleeved mode, the paper tube cutting machine is further provided with a material return unit which specifically comprises a material return ring and a guide rail. The guide rail is arranged below the rotation shaft, and the material return ring is arranged on the guide rail and driven by another air cylinder. According to the paper tube cutting machine, multiple sets of paper tubes can be machined at a time, efficiency is higher, cost is lower, and maintenance is more convenient. In addition, when the machining widths of the paper tubes change, only the distance of the round blades needs to be changed.

Description

technical field [0001] The invention relates to a paper tube cutting machine. Background technique [0002] Paper tubes play a wider role in daily life. For example, tapes or some plastic films use paper tubes as inner cores. [0003] The paper tube cutting machine is a kind of equipment used to cut the whole paper tube into sections. The currently used equipment includes CNC automatic paper tube cutting machine, that is, through the control of the pre-stored program, after setting the cutting parameters of the paper tube , can realize the automatic cutting of paper tubes, which is very convenient. However, automatic cutting machines usually need sensors to assist cutting. The current cost of this type of sensors is still high, and they are also prone to failure. The disadvantages outweigh the advantages. Contents of the invention [0004] The present invention aims to provide a paper tube cutting machine. [0005] In order to achieve the above technical purpose, the...
