After one-time rubber tapping is finished, the adjusting motor 37 drives the guide pipe 32 to continue to rotate through the driving gear 38, the cam 321 toggles the cam sleeve 42, and the rubber tapping motor 44 is driven to move towards the direction away from the rubber trunk through the connecting block 43, so that the cutter retracting of the cutting knife module 4a is realized. The driving gear 38 drives the adjusting screw rod 39 to rotate while adjusting the retracting operation, and the adjusting screw rod 39 is in threaded connection with the adjusting tool holder 41, so that the adjusting tool holder 41 can axially move on the adjusting screw rod 39 to control the position adjustment of the cutting knife module 4a in the vertical direction. When next rubber tapping is carried out, a distance is reserved between the knife edge of the rubber tapping machine and the last spiral knife edge, rubber tapping on the surface of the rubber trunk is uniform, waste is avoided, and the rubber liquid is fully utilized and collected. The cam 321 and the knife adjustment base 41 can slide on the guide tube 32, and when the adjustment screw 39 drives the knife adjustment base 41 to move up and down, the knife adjustment base 41 can drive the cam 321 and the tapping motor 44 to slide along the surface of the guide tube 32.
During the feeding adjustment, the adjusting motor 37 cannot drive the adjusting screw 39 to rotate through the driving gear 38, so as to ensure that the cutting knife 45 does not move in the vertical direction to scratch the bark when the feeding position is located close to the rubber trunk.
When the driving motor 23 is started, the driving gear 31 drives the linkage rod 22 to rotate, and when the linkage rod 22 rotates, the traveling gear 223 is engaged with the outer ring teeth 11 to drive the linkage rod 22 and the moving frame 2a to move along the outer surface of the arc-shaped guide rail 1a in the circumferential direction. Meanwhile, the lower die holder 36 is in threaded connection with the screw section 222, so that when the linkage rod 22 rotates, the lower die holder 36 moves along the axial direction of the linkage rod 22 to drive the upper die holder 35 and the cutting knife module 4a to do lifting movement. Through the combination of the circular motion and the lifting motion, the cutting knife 45 of the cutting knife module 4a forms a spiral knife edge on the trunk of the rubber tree during rubber tapping, and the rubber liquid flows downwards from the knife edge and flows into the rubber cup at the bottom.
After one cutting is completed, the driving motor 23 can move the tapping motor 44 back to the initial cutting position by rotating in the reverse direction. In one tapping operation, when the tapping motor 44 is at the bottom of the adjusting screw rod 39, the cutting blade module 4a can be lifted to the initial position of the adjusting screw rod 39 by the reverse rotation of the adjusting motor 37. During tapping, the rubber can be tapped from top to bottom or from bottom to top relative to the rubber trunk. In tapping, every two cutting edges are spaced to form a spiral shape.
In summary, the present invention has been made to practical samples according to the description and the drawings, and after a plurality of use tests, the utility model can be proved to achieve the expected purpose, and the practical value is undoubted.
