3722.63 ten thousand stere of material yield;Wood chip, wooden 1873.51 ten thousand festmeter of grain converted products;Wood bamboo floor yield reaches
4.79 hundred million square metres;Wood-based plate yield reaches 15360.83 ten thousand steres within 2010, wherein 7139.66 ten thousand cubes of glued board
Rice, 4354.54 ten thousand stere of fiberboard, 1264.20 ten thousand stere of particieboard yield, veneer yield are 2724 ten thousand steres, people
Making plate surface decorative panel yield is 2.95 hundred million square metres.
Multiple blade saw is the machine of common wood cutting, and bore 20cm one 2 meters long or so Pine logs enter spout,
After more than ten seconds 8-9 piece specification or thickness specification not etc. plate from other end discharge hole for discharge, here it is log multi-disc machines
Most significant function-high efficiency, it has feeding, and quickly smooth, high efficiency, low-material-consumption, safe and reliable, cheap etc. are excellent
Point.However, the transmission of the power of existing multi-disc machine is to be transmitted to saw blade main shaft by flywheel shaft, cut to rotate saw blade
It cuts, but often will appear the danger such as de- axis, sliding or off-axis since torque transmits between flywheel shaft and saw blade main shaft, it is former
Because the connection being between flywheel shaft and saw blade main shaft it is not close, insecure caused by, and it is not easy to disassembly and assembly.
Based on this, there is an urgent need for provide a kind of multiple blade saw that performance is stable to solve the above technical problems.
Utility model content

Saw blade main shaft right end also sets up stop nut, and the limit hole of setting and stop nut cooperation, further includes wearing inside flywheel shaft
The left end outer wall of screw rod inside flywheel shaft, screw rod is provided with external screw thread, can screw in saw blade master from flywheel shaft right part
In axis.
Specifically, the saw blade is set on saw blade main shaft by positioning sleeve.
Specifically, the flywheel is set on flywheel shaft by tapered sleeve.
Specifically, the left end outer wall of screw rod is provided with external screw thread, for screwing in saw blade main shaft.
Specifically, cylindrical grooves are arranged in the inside of the saw blade main shaft circular cone straight coupling, internal screw thread is arranged in inner wall, uses
It is connected and fixed in the screw rod.
Specifically, saw blade array arrangement on saw blade main shaft.
Specifically, screw thread is arranged in the saw blade main shaft superolateral surface of the saw blade main shaft right end close to circular cone straight coupling, it is described
Stop nut is threadedly secured on the saw blade main shaft by this.
Specifically, the position that the screw rod screws in saw blade main shaft is located in the saw blade main shaft that stop nut is wrapped up.
The utility model has the beneficial effects that
1. double insurance is arranged in the connection between two axis of the utility model, on the one hand by saw blade main shaft right end and flywheel shaft
Inside carries out taper connection, guarantees concentricity；On the other hand the nut strictly limited on saw blade main shaft is caught in flywheel shaft
In, torque is transmitted, avoids throwing switch, two axis is closely connected and fixed to greatest extent, it is stable and reliable for performance.
2. screw rod can play the role of pull rod, after the assembly is completed, saw blade main shaft is screwed in the right end setting of flywheel shaft
Screw rod can reinforce the axially position precision of two axis during its screw-in, avoid the occurrence of torque bias, damage saw
Piece main shaft.
3. screw rod can also play the role of mandril, damage is generated in saw blade, it, can be by this when equipment needs replacing saw blade
Screw rod continues to rotate, to push saw blade main shaft to rotate, thus easy to disassemble or installation saw blade.
4. the end of flywheel shaft is supported by tapered sleeve as its end, by flywheel shaft and the tight locking of flywheel, two are improved
The bonding strength of person, meanwhile, by the connection means, avoids and spline flywheel shaft is enterprising, to greatly improve winged
The intensity of wheel shaft.
