When a round log is pushed to the saw blade and is in contact with the saw blade by workers, the saw blade is tightened under tension, due to the fact that the annular groove is formed in the wheel rim surface of the upper saw wheel, the probability that an air cushion is formed when air squeezes between the saw blade and the wheel rim surface is eliminated, the saw blade is made to generate multiple-point supporting in the radial direction, and the saw blade is prevented from sliding backwards; due the fact that the saw blade penetrates through the saw-clamping device, the saw blade can maintain good stability, and the band saw blade is prevented from twisting or swing in the saw cutting process.
Description
Technical field
The utility model relates to a kind of timber processing apparatus, specifically refers to a kind of timber band saw device.
Background technology
In existing wood processing technique, the first operation is band saw, is about to round log and is processed into lumps of wood material or plate.In the band saw operation, motor drives bands for band by saw wheel and begins from top to bottom cutting, operating personnel with round log from outside the bands for band pushing to move, round log is cut, and then with manually with remaining round log in pushed home, cut for the second time, with this cyclic process.This kind processing technology is popular long, but also there is more defective: at first, under driven by motor, saw wheel rotates, upper wheel utilizes self inertia, begin to rotate under the drive of bands for band, but the tensioning of saw blade and rate of tension is often unstable in process, easily causes saw blade to fracture if cut to the pimple part of timber, also easily threatens operating personnel's personal safety; When cutting large part timber, also normal generation saw blade is stuck, changes saw blade and extremely bothers, and affects job schedule; The existing monodentate saw blade that adopts can cut during propelling more, pushes back invalid constantly motion, and machinery idle running is wasted a large amount of human and material resources, thereby caused working (machining) efficiency low.
The utility model content
A kind of timber band saw device of the utility model solves timber and adds the easily high problem of stuck or mechanical idle running rate of saw blade rate of tension shakiness in man-hour, saw blade, reaches the purpose of cutting safely and efficiently timber.
The purpose of this utility model reaches by the following technical programs:
The utility model comprises workbench, bearing support and saw cutting mechanism, saw cutting mechanism is placed on bearing support, described saw cutting mechanism is provided with saw blade, upper wheel, lower saw wheel and saw card device, saw blade is on upper wheel and lower saw wheel, and the top that the saw card device is placed in workbench is connected with bearing support, and saw blade passes the saw card device, described upper wheel wheel rim surface is provided with cannelure, lower saw wheel rotates, and saw blade drives upper wheel and rotates, and whole device is in running order.When round log when manually pushing saw blade to and contact with saw blade, saw blade is subject to tension force and is in tight state, because the saw wheel wheel rim surface is provided with cannelure, get rid of the air cushion that may form owing to clamp-oning air between saw blade and wheel rim surface, saw blade is more closely contacted with saw wheel, improve the saw blade job stability, make simultaneously saw blade form multi-point support in radial direction, be conducive to stop saw blade slippage backward, avoided the stress of saw blade to fracture; In the process of saw blade fast turn-around, saw blade passes the saw card device, makes it to keep stability preferably, distortion or the swing of bands for band when preventing sawing.
Further, also comprise motor, the rotating shaft of described lower saw wheel is connected with the output of motor, and motor is the Y4001-4 three phase electric machine, three-phase electricity function positive and negative rotation, thereby drive the rotating shaft positive and negative rotation of lower saw wheel, make saw blade energy bidirectional-movement, the two-way linear motion of saw blade, easier when allowing cutting, particularly run into saw blade counter regulation saw blade just when stuck, make it to break away from stuck state.
Further, described bands for band is Double-tooth band saw, and Double-tooth band saw represents that both sides all arrange serrate saw band, the bidentate saw band can be cut when timber pushes back again, has avoided the idle running of machine, has saved a large amount of electric power and manpower, simplified and add work step and play, improved the efficient of processing.
Further, the wheel rim of described upper wheel is provided with fin, is conducive to the tensioning of saw blade and the maintenance of rate of tension, and saw blade work is stablized more.
Further, as preferably, the material of described saw card device is aluminium alloy, because it is pressed on the bands for band that runs up at work all the time, therefore saw card device except possessing the characteristics that wearability is good, coefficient of friction is little, also possess high temperature resistant, anti-dry grinding function, and distortion or the swing of bands for band can effectively prevent sawing the time.
The utility model compared with prior art, have following advantage and a beneficial effect:
1 the utility model has been avoided the air cushion that may form owing to clamp-oning air between saw blade and wheel rim surface, improve the saw blade job stability, make simultaneously saw blade form multi-point support at width, be conducive to stop saw blade slippage backward, avoided the stress of saw blade to fracture.
The three phase electric machine of 2 the utility model settings can make saw blade do two-way linear motion, and is easier when allowing cutting, particularly runs into saw blade counter regulation saw blade just when stuck, makes it to break away from stuck state.
3 bidentate saw bands of the present utility model can be cut when timber pushes back again, have avoided the idle running of machine, have saved a large amount of electric power and manpower, have simplified work flow, have improved the efficient of processing.
