[0003] There are three steps in pen tip processing: cutting, grinding and drilling. However, each pen tip processing machine can only perform one step, so three different pen tip processing machines are needed to complete the pen tip processing. After the cutting machine cuts the pen tip raw material, the pen tip needs to be transferred to the grinding machine to grind the end of the pen tip into a sharp shape, and then the ground pen tip is transferred to the drilling machine for drilling.

The clamping mechanism is used to clamp the pen tip.

[0039] like Figure 5 and Figure 6 As shown, the rotating mechanism includes a contact shaft 17, a push rod 18 and a stopper 19. The contact shafts 17 are evenly spaced circumferentially connected to the rotating disk 4, and the contact shafts 17 correspond to the conveying holes one by one. The rear side of the slider of the electric slide rail 2 15 is connected to the push rod 18, and the lower part of the push rod 18 is inclined forward so that the push rod 18 can move upward to push the contact shaft 17, thereby rotating the rotating disk 4.

The electric slide rail 12 is controlled to drive the electric grinder 13 to move downward, and the electric grinder 13 drives the wedge block 27 to move downward. The wedge block 27 moves downward into the trapezoidal opening 25 and pushes the clamping plate 24, so that the two clamping plates 24 clamp the pen tip in the delivery hole. The spring 26 is stretched, and then the electric grinder 13 grinds the upper end of the pen tip in the delivery hole. Grinding is performed to grind the upper end of the pen tip into a spike shape, and then the electric slide rail 12 is controlled to drive the electric grinder 13 to move upward, and the electric grinder 13 drives the wedge block 27 to move upward, and the wedge block 27 and the clamping plate 24 are out of contact. Under the action of the spring 26, the clamping plate 24 is reset to release the pen tip in the delivery hole, and this reciprocating process can be used to deliver the ground pen tip to the bottom of the electric drill 16, and the ground pen tip is drilled.
