To achieve the above object, technical scheme is as follows：
A kind of knife striking cylinder for main shaft knife loosening, including be sequentially connected upper end cover, cylinder body, bottom end cover and be arranged at institute
State the piston rod of cylinder interior, the upper end cover upside is provided with gas-tpe fitting, the outer surface of the piston rod upper end with it is described
Inboard wall of cylinder block is slidably matched, and the lower end of the piston rod passes through the bottom end cover, and in the end face connection of the piston-rod lower end
Forge a knife head, the middle part outer wall of the piston rod is cased with helical spring, and the helical spring lower end is mutually butted on the bottom end cover
It is internal.
Preferably, the outer surface of the piston rod upper end is provided with O-ring seal, the O-ring seal is mutually butted on described
Inboard wall of cylinder block, forms annular seal space, it is to avoid leakage causes to be short of power.
Stop screw is provided with inside the bottom end cover, the piston-rod lower end outer wall is provided with groove, and the stop screw is put
In in the groove, when the piston rod moves up and down, the stop screw limits the movement travel of the piston rod, keeps away
Exempt to cause excessive shock cutter.
Further, the bottom end cover lower section is provided with sensor block, and the sensor block is placed on the underpart of the piston rod, the lower end
Lid is externally connected to travel switch, and the travel switch is mutually butted on the sensor block, when in use, is sentenced by the travel switch
The position of the disconnected piston rod, control system is fed back to by signal, realizes the automated handling of cutter.
Design principle of the invention is：Using compressed air, promote piston rod to move down, drive head of forging a knife to move down,
Realize the dismounting of handle of a knife；After stopping supply, piston rod is returned under the active force of helical spring, is moved on head of forging a knife, and realizes handle of a knife
Installation.Meanwhile, the travel switch and sensor block of setting judge the location of piston rod, are easy to the automated handling of cutter.
The beneficial effects of the invention are as follows simple structure is safeguarded and low cost of manufacture, easy to use, can preferably be realized certainly
Dynamicization.
