Abstract

The invention relates to a fixing shaft used for a large-diameter spool. The fixing shaft comprises a fixing shaft body and a shaft sleeve, wherein the diameter of the shaft sleeve is smaller than the diameter of the installed spool. At least two locking strips are arranged on the shaft sleeve. A driving device is arranged at one end of the shaft sleeve. The fixing shaft has the advantages that appropriate shaft sleeves are selected according to different types of spools; at least one locking strip arranged on the shaft sleeve is controlled by the driving device to move on the shaft sleeve and lock the spool on the shaft sleeve, and therefore the device is less frequently installed and detached, installation and detachment are simple, and the structure is simple; the locking strips are pushed by an air pump to move in sliding grooves, and therefore the structure is simple, the locking strips can conveniently slide, and the practicability is high; in the installation process, due to the fact that the diameter of the shaft sleeve is smaller than the diameter of the installed spool, workloads caused when the spool is installed are effectively reduced, installation and detachment are convenient, stability is high, the defect that multiple existing fixing shafts are not convenient to place is effectively overcome, and use cost is reduced.

Description

technical field [0001] The invention relates to a fixed shaft for a barrel core with a large diameter. Background technique [0002] The core is a collection device or a discharge device that can wrap paper products. The existing cores are connected to the equipment through fixed shafts when installed, and different types of cores require different The fixed shafts of different sizes are fixedly connected, so there are the following defects in use: the size of the fixed shaft is not conducive to the placement of the fixed shaft, which increases the cost of use, and the fixed shafts of different sizes require different bearing frames for installation, which is difficult to install and disassemble. Large, poor use effect. Contents of the invention [0003] The technical problem to be solved by the present invention is that different types of cores have a large workload during installation, are difficult to install and disassemble, have poor use effects, are not conducive to...
