Abstract
The utility model discloses a double-sided curved-edge anti-winding cutter specially used for rotatably cutting barks, which comprises a cutter shaft arranged on a cutting machine and four cutter heads fixed on the outer ring of the cutter shaft, wherein each cutter head 2 consists of an arc-shaped cutter edge 3 with the radius of 18.67mm and an arc-shaped cutter back 4 with the radius of 26.01mm, and an arc-shaped curved surface with the radius of 2mm is arranged between the adjacent cutter head 2 and the cutter back 4.
Description
Technical Field
The utility model relates to the technical field of tapping knives, in particular to a double-sided curved-edge anti-winding knife special for rotatably cutting barks.
Background
Natural rubber is one of important industrial raw materials for building modern countries, rubber products such as modern transportation vehicles, daily consumables, modern industrial products and the like are all good in our lives, and the natural rubber also has the characteristic that industrial synthetic rubber cannot be replaced.
However, the last rubber tapping of the bark of the rubber tree dries the residual rubber line, and when the rubber tapping is carried out on the rubber cutting surface through the rotary cutter set, the residual rubber line can be wound on the shaft rod of the rotary cutter set, if the rubber line is not cleaned in time, the residual rubber line on the shaft rod can be wound more and more, the rotating load of the rotary cutter set is increased, the rubber tapping operation is seriously influenced, and therefore the double-sided curve edge anti-winding cutter specially used for rotatably cutting the bark is designed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the defects in the prior art and provides a double-sided curved-edge anti-winding knife which is specially used for rotary cutting of barks.
In order to achieve the purpose, the utility model adopts the following technical scheme:
a double-sided curved-edge anti-winding cutter specially used for rotatably cutting barks comprises a cutter shaft arranged on a cutting machine and four cutter heads fixed on the outer ring of the cutter shaft.
Preferably, the inner diameter of the cutter shaft is 3.3mm, the outer diameter of the cutter shaft is 8.1mm, and the height of the cutter shaft is 3.2 mm.
Preferably, each tool bit consists of an arc-shaped cutting edge with the radius of 18.67mm, an arc-shaped tool back with the radius of 26.01mm and a tool tip, and an arc-shaped curved surface with the radius of 2mm is arranged between the adjacent tool bits and the tool backs.
Preferably, the thickness of the knife back is 2mm, and the thickness of the knife edge is 1 mm.
Preferably, the distance between the tool nose and the axis of the cutter shaft is 25 mm.
Compared with the prior art, the utility model has the beneficial effects that:
1. in the utility model, the cut surface for cutting the barks is neat, and the cut surface has no impurities, so that the resin can flow out smoothly;
2. in the utility model, the curved edge is adopted, so that the frictional resistance is small during cutting and the cutting force is large;
3. according to the utility model, the power consumption can be greatly reduced due to smooth cutting.
The utility model has the advantages of simple structure, convenient use, neat cutting surface for cutting barks, no impurities in the cutting surface, smooth resin outflow, small friction resistance during cutting, large cutting force, greatly reduced required power, low power consumption, winding prevention, energy saving and environmental protection.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Example one
As shown in fig. 1 to 8, the double-sided curved-edge anti-twisting cutter of the present embodiment, which is specially used for rotary cutting of bark, comprises a cutter shaft 1 mounted on a cutting machine and four cutter heads 2 fixed to the outer circumference of the cutter shaft 1.
Example two
The embodiment is improved on the basis of the first embodiment:
in this embodiment, the inner diameter of the cutter shaft 1 is 3.3mm, the outer diameter is 8.1mm, and the height of the cutter shaft 1 is 3.2 mm.
In this embodiment, each tool bit 2 is composed of an arc-shaped cutting edge 3 with a radius of 18.67mm, an arc-shaped tool back 4 with a radius of 26.01mm and a tool tip 5, and an arc-shaped curved surface with a radius of 2mm is arranged between the adjacent tool bits 2 and tool backs 4.
EXAMPLE III
The embodiment is improved on the basis of the first embodiment:
in this embodiment, the thickness of the blade back 4 is 2mm, and the thickness of the blade 3 is 1 mm.
In this embodiment, the distance between the knife edge 5 of the double-sided curved blade and the axis of the knife shaft 1 is 25 mm.
The working principle is as follows: install this blade on electronic tapping knife, the cutting face of cutting bark is neat, and the cutting face is impurity-free, can make the resin flow smooth and easy, and mainly used gathers natural rubber and rosin, owing to take the curve sword, frictional resistance is little during the cutting, and the cutting force is big, reduces required power by a wide margin, low-power consumption, antiwind, energy-concerving and environment-protective.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
