What are the specific structure and characteristics of a tooth rubbing machine?

As we all know, during the production process, the screws perform tooth rubbing operation on the screw teeth through the tooth rubbing machine, and the tooth rubbing machine is equipped with a feeding device that can output the whole row of screw blasting materials on a machine. The tooth rubbing machine has a movable tooth plate and a fixed tooth plate arranged in parallel, forming a tooth rubbing channel between the movable tooth plate and the fixed tooth plate. A guide rail is connected between the tooth rubbing plate and the tooth rubbing plate group. A guide rail is set at the end of the guide rail that can push the output screw blasting material to the tooth rubbing plate group. That is, when the tooth rubbing plate is moved to the guide rail in the tooth rubbing plate group, it can push the screw blasting material to the guide rail in the tooth rubbing plate group, and it can also push the screw blasting material to the guide rail in the tooth rubbing plate group.

However, although the above-mentioned tooth rubbing machine can achieve the expected effect of rubbing the screw blast material, it was also found in actual operation that when the screw blast material is easily stuck in the tooth rubbing channel and is pushed into the tooth rubbing channel by the pushing device, the tooth rubbing group continues to rub the teeth, and the screw blasting material is very easily stuck in the tooth rubbing channel, causing the tooth rubbing machine to be unable to continue the tooth rubbing operation. At this time, if the fault is to be eliminated, it is often moved forward, and the tooth rubbing group must be removed before the stuck screw can be removed before the stuck screw can be locked. The removal of the blast material brings great inconvenience to production and use, and there is still room for improvement in the overall structural design of the tooth rubbing plate group. When the screw blank is defective or skewed during the tooth rubbing process, the stepper motor can stop the rotating circular plate at any position and protrude to fix the pushing member to prevent the pushing member from continuing to push the screw blank, thereby preventing the defective and skewed screw blank from entering the tooth rubbing machine and then stuck in the tooth rubbing machine, making the tooth rubbing machine unable to continue operating the tooth rubbing machine.
