A special high-speed integral rubber tapping tool design method

Abstract

The invention relates to the field of rubber tapping tools, in particular to an electric special rubber tapping tool capable of accurately, quickly and efficiently cutting a natural rubber tree, and having good rubber discharge performance and drainage performance. The invention provides a design method for an integral rotary milling cutter matched with an automatic rubber tapping device. The milling cutter head is formed by rotating the front end surface along the helical line of the conical surface; the rubber liquid drainage groove can be processed while tapping the rubber; the milling cutter head adopts the design of large rake angle, large relief angle and small wedge angle, so that The cutting edge is sharp enough to reduce the cutting heat during the rubber tapping process, which is conducive to the outflow of rubber liquid; the design of the tapered spiral edge and the spiral groove ensures that the blade gradually cuts in during the cutting process, reducing the uneven cutting surface caused by impact; the spiral groove The chips can be discharged smoothly, and the residual wood chips can be avoided to affect the quality of the rubber liquid. The invention greatly improves the rubber tapping efficiency and the rubber output on the premise of meeting the rubber mining standard, and simultaneously reduces the rubber tapping cost.

Description

technical field [0001] The invention relates to a rubber tapping tool, in particular to a design method for a special rubber tapping tool capable of accurately, quickly and efficiently cutting a natural rubber tree, and having good rubber discharge performance and drainage performance. Background technique [0002] Natural rubber is an important raw material in the rubber industry and is widely used in automobile, medical and other fields. At present, natural rubber trees are mainly tapped by the tapper using traditional hand-ground 'V'-shaped knives for push or pull cutting. In the process of rubber tree cutting, the requirements for the slope and depth of the secant line and the control of the secant line are relatively high. A mature rubber tapper can only cut more than 300 rubber trees a day. The rubber tapping work needs to be carried out by the rubber tapping workers when the temperature is low around 3:00 in the morning. Manual rubber tapping not only has high techn...

Problems solved by technology

[0004] In short, the deficiencies in the prior art disclosed by the above-mentioned patents are as follows: ① Although the existing rubber tapping tool can improve the rubber tapping efficiency to a certain extent, the cut surface after cutting is damaged or not smooth enough, which blocks the latex tube of the rubber tree and affects Glue output; ② The sawdust produced by tapping cannot be discharged smoothly, and the residual sawdust cannot be exhausted, which affects the quality of the rubber liquid; ③ During the tapping process, smooth drainage grooves for the rubber liquid to flow out cannot be processed at the same time, causing the glue to flow out along the side. loss, or clogging of the glue flow
