Main cutting edge is provided in the left-hand screw face ascent direction of main cutting knife 491 and secondary bite 492 towards glue surface 16 out
And end cutting edge, for cutting rubber tree bark.
Protective cover 14 is installed on crossbeam 11 by screw, and for avoiding flexible part 4 from hurting operator, protective cover 14 is not
It is interfered with flexible part 4.The baffle (not shown) for striking off chip is internally provided in protective cover 14, baffle setting exists
Flexible part 4 enters 14 side of protective cover, convenient in time striking off chip.For flexible belt, inside protective cover 14 just
The biggish diamond of hardness is arranged for the position in cutting face, can not only remove chip, but also the Grain Falling Off of rust can be made, mention
The automatic growing ability of high flexible band；For flexible chain, the baffle being engaged with cutter 49 is set inside protective cover 14, to scrape
Except chip.Nozzle (not shown) is additionally provided with inside protective cover 14, nozzle follows baffle setting closely, is used for flexible part
4 injection lubricating oil.
In order to provide reliable normal pressure to flexible part 4, driving wheel 2 of the invention, tensioning wheel 51, directive wheel 7 and
Driven wheel 10 is both designed as the structure that upper end has plate washer, and the outer diameter of baffle is slightly less than the lateral surface of flexible part 4, to protect
Demonstrate,prove reliable profiling of the flexible part 4 to rubber trunk.
Flexible part 4 is driven to move by frictional force, by abrasive grain/cutter for being attached on flexible part 4 to natural rubber
Gum skin is cut.To guarantee that cutter is in pilled-in selvedge operation always, motor is selected as rotating counterclockwise herein.
According to the property of helix it is found that being a straight line after its expansion, therefore, flexible profiling rubber cutting apparatus carries out rubber tapping work
When industry, the lateral surface of flexible part 4 needs to be tightly attached to the face 16 of rubber tree, in addition flexible part 4 have with helix angle and
Fixed certain tilt angle, flexible part 4 can be fitted secant 17 well, both imitate to manually opening the face 15 cut out
Shape also can carry out profiling to glue surface 16 out.In addition, the abrasive grain 43 or cutter 49 of flexible part 4 need to be tightly attached to going out for rubber tree
Glue surface 16, and need to apply flexible profiling rubber cutting apparatus certain normal pressure, guarantee the abrasive grain 43 or cutter of flexible part 4
49 can cut certain rubber tree bark thickness.
The course of work
A kind of flexible profiling rubber cutting apparatus of the invention is when carrying out rubber tapping operation, first by the rotation of power-assisted plate 13 to first
Square beam 121 is vertical, and operator's both hands hold handle 6, and ancon is placed on power-assisted plate 13, by flexible profiling rubber cutting apparatus integral end
It rises, crossbeam 11 is adjusted to the consistent position of helix angle for going out glue surface 16 opened and cut with rubber tree, such as helix angle
For 30 ° of position.
Then, integrally push flexible profiling rubber cutting apparatus to rubber trunk, the lateral surface of flexible part 4 is pressed in rubber
The face 15 of trunk carries out profiling to the face 15 cut is manually opened, and the tensioning wheel 51 of two sides is pressed towards centre at this time；And it will be flexible
The cutting face of component 4, which is pressed, goes out glue surface 16 in rubber trunk, forms certain normal pressure to glue surface 16 out, guarantees flexible part 4
Cutter/abrasive grain cut rubber bark.
The switch on handle 6 is opened, rotates flexible part 4 counterclockwise, flexible part 4 is with cutter/abrasive grain to rubber
Bark is cut, and realizes rubber tapping.When flexible rubber cutting apparatus machines away the consumption skin amount of requirement, by flexible rubber cutting apparatus to recession
Out, motor 3 is kept to continue to rotate at this time, the baffle for being arranged on chip remaining on cutter inside protective cover 14 is got rid of,
Tensioning wheel 51 is realized flexible part 4 and is tensioned, to guarantee the normal fortune of flexible part 4 under the action of torque spring 18 at this time
Turn.When remaining chip is removed clean, flexible rubber cutting apparatus is moved to next rubber tree work by switch on blind catch 6
Position repeats above step.
It is worth noting that a kind of flexibility profiling rubber cutting apparatus is applicable not only to manual work, can also be designed as carrying
In the end of mobile platform, automation rubber tapping operation is realized.
