Abstract

The utility model discloses a multi-blade machine for splitting which is suitable for factories or township enterprises which volume-produce bamboo split products, which is characterized in that all chopper are arranged in a straight line on an adjustable tool rest. One end of the tool rest is a hinging fulcrum. The height of the other end of the tool rest can be continuously adjusted. The center of the hinging fulcrum is positioned on the same plane with the cutting chin of each chopper. The tool rest can be inclined in a certain angle theta toward the feed direction of bamboo splits. Because the utility model has the thickness adjusting performance of once multi-blade synchronous stepless type. Production efficiency is over 10 times higher than manual work.

Description

Multi-blade machine for splitting bamboo into thin bamboo strips

The utility model belongs to the bamboo processing equipment manufacturing technology.

In the bamboo wood industrial product of exploitation in recent years, be the large percentage of basic material with the thin bamboo strips used for weaving.As bamboo mat plywood, thin bamboo strips used for weaving glued board, thin bamboo strips used for weaving laminated timber, bamboo-wood plyboard, bamboo wood picking stick etc.Therefore, also increasing to the demand of thin bamboo strips used for weaving.The preparation of thin bamboo strips used for weaving according to tool using with split the different of thin bamboo strip mode, can be divided into and manual split the thin bamboo strip and machinery is split two kinds of the thin bamboo strips.Traditional braiding is based on the manual thin bamboo strip of splitting with thin bamboo strips used for weaving mostly.Not only labour intensity is big, production efficiency is low to split the thin bamboo strip by hand, and splits big, the rough surface of thin bamboo strips used for weaving gauge variability of system, and the shape that overarches at the ring place also has certain operation skill requirement to splitting thin bamboo strip worker.The machinery of China is split existing about more than the 30 years history of the thin bamboo strip, the thin bamboo strip machine of splitting of present each manufacturer production, although it is varied at aspects such as specification, models, concrete structure is also variant slightly, but its essential structure and operation principle all be by a chopper and one to several be critical piece to supply roll, use the rotation of manpower or Motor Drive cylinder, the bamboo bar is divided into two into thin bamboo strips used for weaving by hard-wired chopper under the driving of cylinder.Domestic once had a multi-blade machine for splitting bamboo into thin bamboo strips that chopper is fixedly installed togather with several, because it is former thereby fail to apply to adjust thin bamboo strips used for weaving thickness inconvenience etc.; Also once had with many cutter is evenly distributed and front and back staggered on a face of cylinder, whole mao bamboon realized that by this face of cylinder multitool splits the test of the thin bamboo strip.

Goal of the invention of the present utility model is a kind of production efficiency height of development, uses bamboo wood multi-blade machine for splitting bamboo into thin bamboo strips easy to adjust, to adapt to the new demand that fairly large suitability for industrialized production prepares thin bamboo strips used for weaving in the bamboo processing.

Technical solution of the present utility model is for being loaded on the adjustable blade holders the chopper straight line is uniform some; One end of knife rest is a hinged support, the adjustable height of the other end.The center of hinged support and the blade of each chopper are in same plane.When the relative bamboo bar of adjustable blade holders direction of feed inclination certain angle θ, the bamboo bar of sending to promptly is cut the thin bamboo strip that equates into some thickness.Because the knife rest inclination angle [theta] is adjustable continuously, so the thickness of thin bamboo strip also can be adjustable continuously according to the requirement of product, and adjusts very convenient.

The description of the drawings:

Fig. 1 is an adjustable blade holders assembly schematic diagram.1 is adjusting screw(rod) among the figure, and 2 is adjusting nut, and 3 is knife rest, and 4 is knife-containing block, and 5 is chopper.Spacing between the adjacent chopper is 1;

Fig. 2 is the work schematic diagram of twin-roll feed mechanism.5 is chopper among the figure, and 6 is last cylinder, and 7 is bottom roll.The spacing of every pair of adjacent roller is 1;

Fig. 3 is a kind of complete machine structure schematic diagram of gear drive bamboo wood multi-blade machine for splitting bamboo into thin bamboo strips.8 is drive motors among the figure, and 9 is pulley concial disk, and 10 is main drive gear, and 11 is driven wheel, and 12 is transition gear, and 13 is driven roller, and 14 is cutter holder assembly.

Exemplary embodiments:

Adopt gear drive bamboo wood multi-blade machine for splitting bamboo into thin bamboo strips complete machine structure as shown in Figure 3,6 pairs of cylinders, 5 are housed altogether chopper.The cylinder linear velocity that adopts is 0.5～1.0 meter of a per second; Roller pitch 1=120 millimeter; Split thin bamboo strip Breadth Maximum and be designed to 22 millimeters.When the knife rest inclination angle [theta] was adjusted in 0～2 ° scope, the thickness of thin bamboo strips used for weaving can be adjusted in 0～4.1879 millimeter scope continuously.

The thin bamboo strips used for weaving that adopts the utility model to be split into carries out actual contrast test and shows through making bamboo plywood with the manual thin bamboo strips used for weaving of splitting system, and the made bamboo plywood of the thin bamboo strips used for weaving that two kinds of methods are split system is basic identical aspect unit weight, MOR.But aspect bonding strength, the bamboo plywood that multi-blade machine for splitting bamboo into thin bamboo strips is split the system thin bamboo strips used for weaving is apparently higher than splitting the bamboo plywood made of system thin bamboo strips used for weaving by hand, and it is little that its reason is that multi-blade machine for splitting bamboo into thin bamboo strips is split thin bamboo strips used for weaving surfacing, the roughness of system, so its bonding strength height.

From the destruction situation of bonding strength test specimen, multi-blade machine for splitting bamboo into thin bamboo strips is split the bamboo plywood that the system thin bamboo strips used for weaving is made, and mainly is the failure by shear of bamboo wood, and the bamboo wood destructive rate reaches 90%; And manual splitting made the bamboo plywood that thin bamboo strips used for weaving is made, and mainly is the failure by shear of glue-line, and the destructive rate of bamboo wood only is 10%.Aspect the tensile strength of plane, split by hand bamboo plywood that the system thin bamboo strips used for weaving makes and also be higher than multi-blade machine for splitting bamboo into thin bamboo strips and split the bamboo plywood that the system thin bamboo strips used for weaving is made.The main cause of this respect is that the thin bamboo strips used for weaving back side fiber that multi-blade machine for splitting bamboo into thin bamboo strips is split the system thin bamboo strips used for weaving exists to a certain degree tensile failure phenomenon.But its total physics, mechanical performance index still can reach the specified standard requirement fully.Because multi-blade machine for splitting bamboo into thin bamboo strips has the thick performance of the synchronous stepless accent of multitool one time, production efficiency will be higher than manual more than 10 times, and made thin bamboo strips used for weaving surface roughness is little, thickness evenness is good, can satisfy industrial production requirement fully, so this equipment is specially adapted to produce in enormous quantities the factory or the township enterprise of thin bamboo strips used for weaving goods.

Claims

1, a kind of multi-blade machine for splitting bamboo into thin bamboo strips that is used to split the system thin bamboo strips used for weaving is characterized in that being loaded on the adjustable blade holders all chopper straight lines are uniform; One end of knife rest is a hinged support, and the height of the other end is adjustable continuously; The relative bamboo bar of knife rest direction of feed tiltable certain angle θ.
