Description

Technical Field

[0001] The present application relates to a coil cutting machine, and in particular to a multi-axis stabilization mechanism of a coil cutting machine and the coil cutting machine. Background Art

[0002] A roll cutter is a device used in the tape production process. It is usually used to fix a long tube of film on a shaft and then cut it to obtain several pieces of tape with the same width. One end of the shaft is connected to a chuck, and the other end is open for inserting and removing the film.

[0003] With reference to the patent "CN219114184U - A multi-axis flip-type spindle mechanism of a tape cutter", the existing tape cutter has at least two workstations, which are used for loading and unloading and cutting of the tape respectively. When the tape cutter is switched between the loading and unloading and cutting workstations, the through-shaft will shake with the workstation switch, which may easily cause damage to the chuck used to connect the through-shaft. Moreover, since only one end of the through-shaft is connected to the chuck and the other end is suspended in the air for a long time, the through-shaft is easily deformed, which will affect the insertion and removal of the cut film. Improvements are proposed in this regard. Utility Model Content

The rotation of the rotating frame 1 drives part of the threading shaft 2 to move from the unloading position to the cutting position, and drives the remaining part of the threading shaft 2 to move from the cutting position to the unloading position.

[0034] The multi-axis stabilization mechanism in the present application is connected to the rotating frame 1 and movably cooperates with the free end of the through-shaft 2 to form a closed position for fixing the free end and an open position after the fixation is released.

[0035] The above-mentioned multi-axis stabilization mechanism includes a through-axis stabilization component 3, which is movably connected to the rotating frame 1 and rotates with the rotating frame 1 to switch between the cutting position and the unloading position; wherein, the through-axis stabilization component 3 includes a first part and a second part, the first part corresponds to a part of the through-axis 2, and the second part corresponds to the remaining part of the through-axis 2, the first part and the second part are respectively hinged to the rotating frame 1, and rotate around their own hinges to form the above-mentioned closed position and open position.

[0036] Furthermore, the first part includes a first driver 4 and a first stabilizing plate 31 controlled by the first driver 4, the first driver 4 controls the first stabilizing plate 31 to flip, so that the first stabilizing plate 31 switches between the closed position and the open position; the second part includes a second driver 5 and a second stabilizing plate 33 controlled by the second driver 5, the second driver 5 controls the second stabilizing plate 33 to flip, so that the second stabilizing plate 3 switches between the closed position and the open position.
