Description
Technical field
The invention belongs to bamboo processing field, relate generally to thick bamboo tube and the accurately a kind of mechanism to the heart of broken bamboo cutter when thick bamboo tube is split into the equal bamboo chip of width.
Background technology
Summer sleeping bamboo mat production process mainly contains: broken bamboo, hack, wire drawing, braiding, tape edge etc., it is the first operation of producing summer sleeping bamboo mat that thick bamboo tube is split into the bamboo chip that width is equal.When broken bamboo, thick bamboo tube microcephaly aims at broken bamboo cutter shock, and the center of thick bamboo tube must with the center of broken bamboo cutter, guarantee thick bamboo tube is split into the bamboo chip that width is equal.Root Ju is hacked, wire drawing requirement, and the chord length width B of microcephaly's bamboo chip inner radius of cutting open must not be less than 21mm, is then processed into 20mm rear plate opening, wire drawing through wide.Because the diameter of thick bamboo tube is different, if adopt the broken bamboo cutter of identical blade number, the bamboo chip width of cutting open can increase and become large along with the diameter of thick bamboo tube, so not only greatly increase cutting output, and waste raw material, so the size of diameter that must root Ju thick bamboo tube when broken bamboo is changed the broken bamboo cutter of respective blade number at any time; Because every thick bamboo tube has bending in various degree at length direction, on cross section, be all oval substantially, and thick bamboo tube also have concentric reducer, so must solve the centering problem at Yu Pozhudao center, thick bamboo tube center when broken bamboo.The broken bamboo machine of current domestic use does not have thick bamboo tube concentric mechanism accurately substantially, in the cone by manually thick bamboo tube being enclosed within brokenly to bamboo cutter front end (as shown in Figure 1), and minimum diameter is determined in the thick bamboo tube inside diameter ranges that in the size of the cone broken bamboo cutter that is root Ju, different blade numbers adapt, because the cone diameter in the broken bamboo cutter of every handle can not change, so this structure cannot make the accurate centering in thick bamboo tube Yu Pozhudao center, generally do not cut a bamboo chip width in thick bamboo tube open not etc., sometimes differ greatly, the bamboo chip width so just making is less than 20mm, cause and do not pull out bamboo silk width not etc., some bamboo chip width are very large, cause cutting output to increase, the life-span that equipment is hacked in impact.
Summary of the invention
Thick bamboo tube and broken bamboo cutter concentric mechanism accurately when the object of the present invention's design is to provide a kind of broken bamboo.
Technical solution of the present invention is: a kind of broken bamboo machine thick bamboo tube concentric mechanism, comprise inner cone, spring base, extension spring, strut, bearing pin, flat key, strut supporting member, spacer pin, axle, it is characterized in that: inner cone adopts and is threaded with axle, strut supporting member is enclosed within axle middle part, and realize the circumferential of strut supporting member and axle with flat key and fix, respectively three struts are hinged in three grooves of strut supporting member with bearing pin, spring base is equipped with on three strut front end both sides, three extension spring two are hooked on respectively on spring base, make three struts form a pre-small post-large cone, and concentric with inner cone and axle, three struts can swing around bearing pin in the time being subject to the extruding of thick bamboo tube inwall, to adapt to the variation of different thick bamboo tube microcephaly internal diameters and at broken bamboo front support thick bamboo tube.For the bamboo chip of width such as obtaining, need make thick bamboo tube center and broken bamboo cutter center superposition; For improve bamboo wood utilization rate, reduce the cutting output of wide processing, the thick bamboo tube that inside diameter ranges is different need be changed the broken bamboo cutter of different blade numbers, the bamboo chip width that guarantee is cut open had both been greater than 21mm, was also unlikely to the bamboo chip that is broken away too wide.Before broken bamboo, after thick bamboo tube concentric mechanism afterbody is packed into broken fixing in the centre bore of bamboo cutter, thick bamboo tube concentric mechanism is concentric with broken bamboo cutter; When broken bamboo, push brokenly thick bamboo tube to bamboo cutter by push pedal, thick bamboo tube microcephaly puts after the cross section that thick bamboo tube concentric mechanism is pushed over three bearing pin places, and thick bamboo tube microcephaly inwall starts to contact with strut; In the time that three struts all contact with thick bamboo tube microcephaly inwall, thick bamboo tube microcephaly inwall can make three struts synchronously swing around three bearing pins, until three struts enter into when thick bamboo tube is interior supports thick bamboo tube by three strut afterbodys, three struts stop swinging, now thick bamboo tube is concentric with thick bamboo tube concentric mechanism, concentric with broken bamboo cutter; Push pedal continues to move ahead, and thick bamboo tube microcephaly is pushed to while colliding with the edge of a knife that breaks bamboo cutter, and broken bamboo starts, and the edge of a knife of broken bamboo cutter is split into bamboo chip along the longitudinal machine direction of thick bamboo tube by thick bamboo tube.Because the axial dimension of thick bamboo tube concentric mechanism is subject to the restriction of push pedal and edge of a knife spacing, its spacing is too little, and the inner cone in thick bamboo tube concentric mechanism is encountered in push pedal meeting; Its spacing is too large, thick bamboo tube can not be cut open completely, so the axial dimension of thick bamboo tube concentric mechanism of design must guarantee that in situation that thick bamboo tube can be cut open completely, inner cone is not encountered again in push pedal, therefore, accessory size in the thick bamboo tube concentric mechanism packing in the broken bamboo cutter of different blade numbers is slightly differentiated, but its operation principle is identical.Limited because the broken bamboo cutter of every handle adapts to thick bamboo tube inside diameter ranges, so answer the size of root Ju thick bamboo tube internal diameter to change the broken bamboo cutter of different blade numbers while breaking bamboo.Following table has only enumerated 6 the corresponding relation of inside diameter ranges applicable to broken bamboo cutter (blade number from 7 to 12) and thick bamboo tube microcephaly inside diameter ranges, the bamboo chip width of cutting open and thick bamboo tube concentric mechanism:
In the applicable inside diameter ranges of thick bamboo tube concentric mechanism in table in the broken bamboo cutter of every handle
with
in difference respective figure 2
with
as the broken bamboo cutter of 7 cuttves is housed, the applicable inside diameter ranges of thick bamboo tube concentric mechanism is
On the cylindrical of described strut supporting member, be evenly equipped with three spikes, in the middle of three spikes, have vertically three grooves, its groove width equates with strut thickness.
Described inner cone rear end face, have three boss on 120 degree positions, is milled with respectively a radial slot in the middle of three boss, and its groove width equates with strut thickness; In the time that inner cone is tightened in axle, guarantee that three grooves on rear end face are just in time relative with three grooves on strut supporting member, three struts are hinged in strut supporting member and after three extension springs are hooked on spring base with bearing pin, three strut front ends are also embedded into respectively in three grooves on inner cone rear end face (as shown in Figure 6), its effect is the teeter of three struts of restriction, also can prevent the thread looseness between inner cone and axle simultaneously.
Three strut afterbodys in described thick bamboo tube concentric mechanism have a U-shaped groove, with the correspondence position of strut supporting member on be fixed with a spacer pin, spacer pin can limit the amplitude of fluctuation of three struts; In the time that three struts synchronously swing around three bearing pins, its hunting range inside diameter ranges applicable with thick bamboo tube concentric mechanism is corresponding.
Advantage and good effect that the present invention has are: adopted after thick bamboo tube concentric mechanism, as long as push pedal pushes through thick bamboo tube microcephaly the cross section at three bearing pin places in thick bamboo tube concentric mechanism, no matter whether bending, the whether oval automatic centering that can realize thick bamboo tube and broken bamboo cutter of cross section of thick bamboo tube; Compared with the concentric mechanism adopting with existing broken bamboo machine, heart precision is improved greatly, realized decile and cut open.
