Special high-speed integral rubber tapping tool and design method

Abstract

The invention relates to the field of rubber tapping tools, in particular to an electric special rubber tapping tool which can accurately, quickly and efficiently cut a natural rubber tree and has good rubber discharging performance and drainage performance. The invention provides a design method of an integral rotary milling cutter matched with an automatic rubber tapping device. The milling cutter head is formed by rotating the front end face along a conical surface spiral line; rubber liquid drainage grooves can be processed while rubber is tapped; the milling cutter head adopts the design of a large front angle, a large rear angle and a small wedge angle, so that a cutting edge is sharp enough, cutting heat in the rubber tapping process is reduced, and outflow of rubber liquid is facilitated; the design of the conical surface spiral blade and the spiral groove is adopted, it is guaranteed that the blade gradually cuts in the cutting process, and unevenness of the cutting face caused by impact is reduced; cuttings can be smoothly discharged through the spiral groove, and the situation that the quality of the rubber liquid is affected by residual sawdust is avoided. The rubber tapping efficiency and the rubber output are greatly improved on the premise that the rubber tapping standard is met, and meanwhile the rubber tapping cost is reduced.

Description

technical field [0001] The invention relates to a rubber tapping tool, in particular to a special rubber tapping tool capable of accurately, quickly and efficiently cutting natural rubber trees, and having good rubber output and drainage performance and a design method thereof. Background technique [0002] Natural rubber is an important raw material for the rubber industry and is widely used in automotive, medical and other fields. At present, the rubber tapping method of natural rubber trees is mainly that rubber tapping workers use traditional manual grinding 'V'-shaped knives for push or pull cutting. During the rubber tree cutting process, there are high requirements on the secant line slope and depth, and the control of the secant line. A skilled rubber tapping worker can only cut more than 300 rubber trees a day. The rubber tapping work needs to be carried out by tapping workers at around 3 o'clock in the morning when the temperature is low. Manual rubber tapping no...

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
