Description

Multi-blade band saw and saw wheel rotating method

Technical field

The present invention relates to material process equipment field, is a kind of multi-blade band saw and saw wheel rotating method.

Background technology

At present, the normally a pair of saw wheel of the band sawing machine of selling on the market is installed a saw blade, and working method is more single when being used for processing materials, and efficient is lower.Although the band sawing machine market of many saw blades is existing, most band sawing machines still have only the mounting means of a saw blade by a pair of saw wheel, for increasing work efficiency, have to organize single band sawing machine makes up more, make its structure comparatively complicated, energy resource consumption is bigger, regulates and comparatively inconvenience of operation.Existing slasher because saw blade is thicker, causes the material waste bigger, and saw blade and material contact-making surface are bigger during sawing, especially can not stably come the thicker material of sawing with ultrathin circular saw blade, thereby directly influence its scope of application and effect.

Summary of the invention

The present invention is to Chinese patent announcement CN1850409A, application number 200610051637.9, and denomination of invention: step multi-blade band saw, prior art improves.For overcoming above-mentioned deficiency, purpose is to provide a kind of multi-blade band saw and saw wheel rotating method to this area, makes it solve the known technology structural design and owes perfect technical problem, has high efficiency, and energy resource consumption is little, many saw blades saw of working stability.The objective of the invention is to adopt following technical scheme to realize.

A kind of multi-blade band saw, this band sawing machine comprises frame, workbench, saw wheel, saw blade, and saw wheel is provided with initiatively saw wheel group and passive saw wheel group, and passive saw wheel group is fixed by pin, does not do relative motion.Its design main points are respectively equipped with interior wheel, middle wheel, foreign steamer in active saw wheel group and passive saw wheel group.Interior wheel, middle wheel, foreign steamer all connect with axle, and the interior wheel of passive saw wheel group, middle wheel, foreign steamer connect with another axle.The diametric plane of wheel, middle wheel, foreign steamer is different diameters promptly, and saw blade connects master, the interior wheel of passive saw wheel group, middle wheel, foreign steamer respectively.Interior wheel, the foreign steamer of passive saw wheel group all are provided with duplex bearing, and middle wheel is provided with that single shaft holds or duplex bearing.

A kind of saw wheel rotating method of multi-blade band saw, the design main points of this method are that the active saw wheel group of multi-blade band saw is connected on the disalignment respectively, initiatively the saw wheel group drives passive saw wheel group rotation, the foreign steamer of passive saw wheel group, interior wheel is provided with duplex bearing, in wheel be provided with that single shaft holds or duplex bearing, the foreign steamer of passive saw wheel group and interior wheel are near middle wheel, saw blade is made up of three saw blades, these three saw blades are connected to the master, wheel in the passive saw wheel group different-diameter, middle wheel, the diametric plane of foreign steamer, interior wheel, middle wheel, outer crop rotation relative motion, and drive the saw blade rotation, possess metastable circumference and rotate.Realized interior wheel, middle wheel, the position when foreign steamer rotates so not necessarily together, but running that can be synchronous, each saw blade is in even tension, reaches saw blade sawing material purpose smoothly.

Wheel, saw blade are provided with crown and straightway in described, and the straightway of certain-length between crown prevents that the saw blade crown is overstocked, make the crown bottom produce slight crack easily, cause the saw blade fracture.

Described workbench is provided with the lifting balladeur train and by frame, screw is fixing by frame, and the lifting balladeur train connects by frame, by having set up the saw card.The lifting balladeur train is provided with bracing frame, sliding pin and screw.By sliding pin and screw, regulate bracing frame position of vertical direction up and down in the lifting balladeur train.Bracing frame is provided with top wheel and another saw card.Bracing frame connects threaded top wheel, regulates the horizontal level of top wheel by regulating screw thread, and the top wheel is separately fixed at the diverse location on the bracing frame, and the vertical direction when preventing saw blade sawing material moves backward.The saw of two uniform distances on bracing frame and the workbench fastens parallel distance between saw blade, saw blade passes saw card groove respectively, the move left and right of the horizontal direction when preventing saw blade sawing material, and block the distance of finely tuning between saw blade by the saw of changing two different spacing grooves.Workbench connects automatic feeding, and automatic feeding is rotated by the feeding motor and drives the chain rotation, and material is close to by frame, and chain drives rotary drum material is sent into the saw blade sawing automatically.Frame is provided with timber backplate and sweep-up pipe, and the timber backplate inserts in the side groove and rearward recess of frame, prevents that the sawdust that saw blade sawing material produces is involved in main, passive saw wheel group.Sweep-up pipe connects dust catcher, with the sawdust sucking-off, guarantees the multi-blade band saw operate as normal.

Described frame is made as the multi-blade band saw of horizontal or vertical formula according to frame shape difference; For increasing work efficiency, frame is made as combined type multi-blade band saw (seeing Figure 12 and Figure 13) in addition in conjunction with two groups of masters, passive saw wheel group simultaneously, and regulates the spacing of two groups of masters, passive saw wheel group by the frame adjusting handle.

Multi-blade band saw provided by the invention has improved operating efficiency, and simple in structure, low cost of manufacture, working stability, the characteristics of good energy-conserving effect.
