Problems solved by technology

[0002] When the current multi-band saw needs to cut boards of different thicknesses, it is necessary to change the lateral distance between two adjacent band saw blades by replacing the upper pulleys with different diameters, thereby changing the thickness of the cut wood board; this method is too traditional. The upper and lower pulleys need to be replaced, and the band saw blade needs to be replaced. The operation is extremely complicated, time-consuming and labor-intensive, and the efficiency is low.

Embodiment 1

[0024] Embodiment one: if Figure 1~7 As shown, a multi-band saw with adjustable cutting thickness includes a frame 100, and at least one group of band saws is arranged on the frame 100, and each group of band saws includes a plurality of upper pulleys with increasing diameters coaxially arranged 200 and the lower pulley 300 and a plurality of band saw blades 400 forming a multi-circle ring structure, the upper and lower parts of the frame 100 are respectively provided with a square shaft 500 for installing the upper pulley and the lower pulley, each upper pulley 200 and the lower pulley 300 are rotatably matched with a connection plate 520 through a bearing 510, and the connection plate is set on the square shaft 500 and can move left and right relative to the square shaft 500. Position adjustment mechanism; each connection plate is equipped with an independent adjustment mechanism on the square shaft, through which the left and right positions of the connection plate can be ...

Embodiment 2

[0035] Embodiment 2: Since the multi-band saw can use the lower pulley as the driving pulley, or the upper pulley as the driving pulley, the difference between this embodiment and Embodiment 1 is that the upper pulley is used as the driving pulley. The drive shaft is fitted with a plurality of upper pulleys corresponding to one by one and pulleys with decreasing diameters, and the pulleys are connected to the corresponding upper pulleys through transmission belts; the upper pulleys are provided with belts for covering the transmission belts. The installation part is provided with a belt groove on the belt installation part, and the diameters of the belt installation parts of all the upper pulleys are the same.

[0036] A working method for multi-band saws with adjustable cutting thickness as described above. Insert the hexagonal wrench into the corresponding worm through the through hole, and turn the worm through the action of the screw sleeve and the screw so that the upper a...

Abstract

The invention relates to a multi-band saw with the adjustable cutting thickness and a working method thereof. The multi-band saw comprises a machine frame, at least one set of band saws is arranged onthe machine frame, each set of band saws comprises a plurality of upper band wheels and lower band wheels arranged coaxially and with the gradual-increasing diameters and a plurality of band saw strips forming a multi-ring annular structure, square shafts used for mounting the upper band wheels and the lower band wheels are arranged at the upper and lower parts of the machine frame correspondingly, each upper band wheel and each lower band wheel are in rotatably matched with connecting discs through bearings respectively, each connecting disc is mounted on the corresponding square shaft in asleeving mode and can move left and right relative to the corresponding square shaft, and an adjusting mechanism used for adjusting the left and right positions of each connecting disc is arranged onthe corresponding square shaft. The multi-band saw with the adjustable cutting thickness achieves the rapid adjustment of thickness cutting, and does not need to replace the upper and lower band wheels of different diameters to adjust, the adjustment is simple, the operation is simple, the time and labor are saved, the processing progress is ensured, meanwhile, all the band saw strips can maintainthe consistent linear speed for working, and the fact that the service life of all the band saw strips is tend to be consistent is ensured.

Description

technical field [0001] The invention relates to a multi-band saw with adjustable cutting thickness and a working method thereof. Background technique [0002] When the current multi-band saw needs to cut boards of different thicknesses, it is necessary to change the lateral distance between two adjacent band saw blades by replacing the upper pulleys with different diameters, thereby changing the thickness of the cut wood board; this method is too traditional. The upper and lower pulleys need to be disassembled and replaced, and the band saw blade needs to be replaced. The operation is extremely complicated, time-consuming and labor-intensive, and the efficiency is low. Contents of the invention [0003] In view of this, the object of the present invention is to provide a multi-band saw with adjustable cutting thickness and its working method which is easy to use and simple to operate, and realizes rapid adjustment of cutting thickness. [0004] The present invention is re...
