Embodiment Construction

[0012] see figure 1 , the present invention consists of a top 1, a base 2, a top sleeve 3, and an automatic locking device. The top sleeve is located in the axial hole of the base, and the top shank is located in the tapered hole of the top sleeve. Described automatic locking device comprises stepper motor 14, driving gear 13, intermediate wheel 12 and driven gear 11, screw shaft 4, top cover nut 6, limit switch 8, fork 10 and hold down spring that are meshed in sequence, Wherein, the top sleeve nut is fixedly connected to the top sleeve and spirally fits with the screw shaft. The driving gear is fixed on the output shaft of the stepping motor, the driven gear is fixed on the right side of the screw shaft, and the stepping motor forms a transmission connection with the screw shaft through gear transmission. The hold-down spring is a disc spring 7 that can bear a relatively large load with a small deformation. And the one-way thrust ball bearing 9, the one-way thrust ball bea...

Abstract

An automatic locking tailstock used for a printing ink roller cleaning machine is used for solving the problems of inconvenient operation and insufficient clamping force of the current roller cleaning machines. The technical proposal of the invention is as follows: the tailstock comprises a center, a base, a center sleeve and an automatic locking device; wherein, the center sleeve is positioned in an axial hole of the base; a center shank is positioned in the center sleeve; the automatic locking device comprises a stepping motor, a drive assembly, a screw shaft, a center sleeve nut, a limit switch, a swing rod and a holddown spring; the center sleeve nut is fixedly connected with the center sleeve and is in spiral fit with the screw shaft; the stepping motor is in drive connection with the screw shaft by the drive assembly; the holddown spring is positioned at the right side of the screw shaft shoulder; both ends of the swing rod are respectively corresponding to the right end of the screw shaft and a button of the limit switch. The tailstock has simple structure, compact shape, convenient operation and good locking effect, is fitted with the automatic cleaning part of the ink roller and can realize automatic cleaning of the ink roller. The design concept of the tailstock also has referential significance towards related equipments.

Description

technical field [0001] The invention relates to a printing device, in particular to an automatic locking tailstock for a printing ink roller cleaning machine, and belongs to the technical field of printing devices. Background technique [0002] The ink roller of the printing machine is one of the main components on the printing machine. The ink roller of the printing machine needs to be cleaned frequently. The cleaning problem has always been a common problem in the printing industry. Because the length, diameter, and shaft end structure of printing machine ink rollers are different, it is difficult to realize automatic cleaning of printing machine ink rollers. So far, many manufacturers in the industry basically still use the original method of manual cleaning. This backward cleaning method has low work efficiency and high labor intensity. In addition, during the cleaning process, workers directly contact cleaning liquid and other chemicals with their hands, which will also...
