The driving shaft 14 can transmit torque through the ridges 15 on its surface, and can drive the feeding screw 11 to rotate through the shaft sleeve 13. During the rotation of the feeding screw 11, it can horizontally push the materials and feed them into the inside of the fuselage 1. The materials are not easily blocked in the feeding cylinder 4. The baffle plate 12 can block the materials and prevent the materials from contacting the shaft sleeve 13. During this process, the driving gear 23 can make the driven shaft 1601 rotate with the driving shaft 14 through the driven gear 1602 of the reciprocating assembly 16, and the driven shaft 1601 can drive the guide cam 1603 to rotate. The guide cam 1603 can drive the shaft sleeve 13 to reciprocate through the slide plate 22, so that the feeding screw 11 can reciprocate during rotation, disturbing the materials, preventing the materials from being blocked inside the feeding screw 11, and maintaining the uniformity of feeding.

[0031] The staff loosen the bolts fixing the end cover 7 and disassemble the end cover 7, and can horizontally take out the reciprocating assembly 16 and the feeding screw 11, which is convenient for their maintenance and repair.
