Screw capping head for plastic bottles

This capping head applicable for screw capping machine,it is a very important part of drink bottles capping machine.

The shell of capping head tightening the mouth of slide bushing by screwthread,when the slide bushing begin to public turn, self-turn, upper and lower movement, Capping heads accordingly synchronized movement, into the capping head has is adverses magnetic substance.

1, through the suction phase magnetic body to ensure that the appropriate capping torque, torque of capping heads through the distance by two groups between magnetic substance to ensure it , when the torque of capping heads exceeds stated numerical value,to between two magnets The relative sliding, in order to achieve self-stopped of the toothes of capping heads ,about adjusting ring of the capping heads, in order to downward force of capping,in working process, allowed to the 2 part of capping head , along to the direction of axle,compression 2-6mm, the 3 part of spring is In order to prevent sling bottle and remove caps of capping heads, in order to ensure the normal operation of the machine.

2,The torque of capping head: unscrewing the nuts and fixed bolts at the magnetic adjustment ring, then turning it right to increase the torque and to the contrary turning left to decrease the torque.

3,note:the part 4 of adjusting ring of magnetic,the 5 part of the pole of pushing out caps have adjusted,please dont adjust easliy.
