Rubber Electric Tapping Knife Rotary Head

Abstract

The invention discloses a rotary tool bit of an electric rubber tapping knife. The rotary tool bit is composed of a cylindrical knife body, an axial spiral blade set, a radial spiral blade set and a motor shaft fixing hole. The radial spiral blade set is arranged at the top end of the axial spiral blade set. The diameter of the cylindrical knife body is 9-10 mm. The height of the portions, outside the cylindrical knife body, of axial spiral blades is 1-2 mm. The included angle between the axial spiral blades and the axis is 30-35 degrees. The axial spiral blade set comprises 4-6 blades. Each axial spiral blade is composed of an axial blade bevel and an axial blade knife edge. Each radial spiral blade is composed of a radial blade bevel and a radial blade knife edge. The axial blade knife edges and the radial blade knife edges are all spiral. The rotary tool bit is simple in structure, convenient to use and capable of being driven by mechanical force to efficiently rotate at high speed and meanwhile cut rubber tree bark in the longitudinal direction and the transverse direction.

Description

technical field [0001] The invention relates to a cutting head of an electric rubber tapping knife, in particular to a rotary cutting head of an electric rubber tapping knife which can cut rubber bark vertically and horizontally, can quickly and labor-savingly complete the rubber tapping work, and greatly reduces the requirements for the rubber tapping technology of the rubber worker. . Background technique [0002] At present, rubber tapping in natural rubber production mainly follows decades of manual rubber tapping. Using a "V"-shaped traditional rubber tapping knife to cut rubber bark is not only labor-intensive and labor-intensive, but also requires relatively high technical requirements for rubber workers. It is not easy to control the depth and thickness of the rubber tapping port, and it is easy to cause different depths of the glue line, damage the rubber tree wood layer, cause dead skin disease or other diseases, thereby reducing the latex output and causing greate...

AI Technical Summary

Problems solved by technology

However, when tapping rubber, it is necessary to cut the rubber bark vertically and horizontally at the same time, and the production has strict restrictions on the amount of skin consumed and the depth of tapping. In this way, the rubber bark can be cut quickly, efficiently, and at the same time in the vertical and horizontal directions. The thickness of the bark must be strictly controlled between 1.0 and 1.5 mm each time. position), otherwise it will hurt the gum tree and bring huge losses to production
