Description
Technical field
The utility model belongs to bamboo processing technical field, is related to the technology to carrying out machining into section bamboo trunk inwall,
Especially it is used for the tool equipment for removing the tabasheer on bamboo trunk inwall.
Background technology
Mainly there is broken cut to splice and flatten two ways the mode that raw bamboo is processed into bamboo board at present, the former more passes
System, it is to break raw bamboo first to cut and be processed into regular square bamboo cane, then bamboo board is spliced to form by square bamboo cane；The latter is in recent years
A kind of new technology to come is slowly promoted, directly circumferentially flattening forms bamboo clappers to the technology by raw bamboo by a set of extension tech
Material.The bamboo board good integrity obtained by whole bamboo expansion mode, seamless, without using glue, there is replacement tradition broken greatly at present
Cut the trend of splicing process processing bamboo board.Whole bamboo flattening process is usually：First by raw bamboo be truncated into suitable length into section thick bamboo tube,
The internal segment of thick bamboo tube is removed, then processes the gap of an insertion vertically on thick bamboo tube, afterwards using the methods of steaming, bake, boiling
Sofening treatment is carried out to thick bamboo tube, the thick bamboo tube after softening is formed into tabular along gap expansion pressing finally by the mode such as rolling.
During bamboo is deployed, in order to avoid caused by bamboo green grass or young crops and tabasheer and internal segment quality are hard, pliability is poor
Cracking, also need to tabasheer, the blue or green removal of bamboo in the pre-deployed.Internal segment, tabasheer, bamboo green grass or young crops are gone typically in the advance of sofening treatment process
OK.Go bamboo is blue or green typically to be rotated using thick bamboo tube, cutter is carried out in the mode of thick bamboo tube side feed vertically, goes internal segment and tabasheer then more
Fixed using thick bamboo tube, cutter rotates into thick bamboo tube from thick bamboo tube one end and completes internal segment, the cutting of tabasheer removes.
Although de-etiolation is similar with the action process of internal segment is removed, in equipment in addition to cutter, remainder is essentially identical, existing
Have in technology, go internal segment and de-etiolation to still need to carry out respectively, main reason is that not yet exploitation has integrated de-etiolation and goes internal segment double
The cutter of weight function.
The structure design of existing de-etiolation cutter, which is unfavorable for integrating, goes internal segment function.Using publication No. as in CN105437331A
Exemplified by de-etiolation cutter disclosed in state's utility application disclosed by bamboo pole de-etiolation machine, knife rest is symmetricly set on（Body）On
Two cutter hubs and knife rest on chute coordinate, can be radially slided in chute, compression spring is set between two cutter hubs.It is this to set
It is the same thick bamboo tube for cutter being adapted to different thicknesses of one side to put purpose, on the other hand because thick bamboo tube is not ideally
Cylindrical drum, not only the thick bamboo tube internal diameter of axially different position have differences, the barrel of thick bamboo tube any position nor the circle of rule,
That slides cutter hub sets the continuous change that radius can be adapted in rotary course.
In its natural state, under compression spring effect, two cutter hubs slide to outermost to above-mentioned this de-etiolation cutter respectively,
The distance at the blade end of two cutter hubs is more than the internal diameter of thick bamboo tube to be processed, and when processing operation starts, two cutter hubs on cutter need
To be slided under the work of the extruding of thick bamboo tube wall to axle center, thick bamboo tube can be entered.Therefore, be arranged on knife rest front end has guiding oblique
The guide portion in face is essential.But the presence of guide portion, can not only make knife it is bigger, it is heavier, can also hinder internal segment
Chip removal, so being difficult to internal segment blade will be gone to be integrated on cutter.Realize to integrate on de-etiolation cutter and go internal segment function, then need
Spring cutter structure is removed in change.
On the other hand, because cutter hub realizes out knife under compression spring effect, when compression spring elastic force is larger, especially meet
To serious irregular body, most probably there is card and stop or cause body to rupture under impact.
The content of the invention
The purpose of this utility model is, for existing de-etiolation and the present situation for going internal segment operation to carry out respectively, to go for existing
Yellow cutter volume and weight is big, and structure is unfavorable for integrated the problems such as going internal segment function, proposes that one kind goes for bamboo
The improved cutter scheme that this irregular inner surface of tube body of cylinder is processed, its improved structure can be not provided with the guiding of front end
Portion, structure is more simplified, is advantageous to control cutter volume and weight, also provides possibility to integrate other blades in cutter front end.
Another purpose of the utility model be it is further proposed that it is a kind of using the utility model cutter be used for it is this to thick bamboo tube irregular
The equipment that inner surface of tube body is processed.
In order to realize above-mentioned purpose of utility model, the utility model proposes a kind of for processing table in irregular pipe body first
