Tube cutting shaft strengthening and attaching device

Abstract

The invention discloses a tube cutting shaft strengthening and attaching device. The device is used for a paper tube cutting machine, and the paper tube cutting machine is provided with a tube cuttingshaft used for sleeving a paper tube; the tube cutting shaft strengthening and attaching device comprises an elastic sleeve, a support, a tip cone, a sleeve, a tip cone moving mechanism and a sleevemoving mechanism, wherein the elastic sleeve sleeves the tube cutting shaft, the side face of the free end of the tube cutting shaft is provided with a conical surface, the end face of the free end ofthe tube cutting shaft is provided with a conical groove, and the tip cone moving mechanism and the sleeve moving mechanism are correspondingly arranged on the support; and the tip cone moving mechanism is fixedly connected with the tip cone so as to drive the tip cone to be inserted into the conical groove of the tube cutting shaft, and the sleeve moving mechanism is fixedly connected with the sleeve so as to drive the sleeve to clamp the conical surface of the tube cutting shaft. According to the device, the sleeve cooperates with the taper of the tube cutting shaft, so that attaching of the tube cutting shaft is easier to achieve; and meanwhile, pressure transmission is carried out, so that the elastic sleeve is enabled to be expanded to realize the circumferential fixation of the paper tube, the accurate size of cutting the paper tube is guaranteed, and the paper tube is neat in section and consistent in size after cutting.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a pipe cutting shaft abutment abutting device. Background technique [0002] The pipe cutting shaft is used for the paper tube cutting machine. The paper tube cutting machine has a pipe cutting shaft for socketing the paper tube. When one end of the pipe cutting shaft is fixed and the other end is not fixed and suspended, the pipe cutting shaft will be in a skewed state, which cannot be guaranteed. The precise size of the first action (cutting the paper tube) will cause the section of the cut paper tube to be skewed and the size inconsistent. Contents of the invention [0003] Aiming at the technical problem existing in the prior art that the pipe cutting shaft with one end fixed is likely to cause the pipe cutting shaft to be skewed when cutting the paper tube, the present invention provides a pipe cutting shaft abutting device that can prevent the pa...
