Problems solved by technology

[0002] The current multi-band saw mainly uses the lower pulley as the driving pulley, and the lower pulley adopts an integral structure or is set on the same drive shaft to rotate synchronously; because the lower pulley rotates at the same speed, this results in the pulley with a larger diameter If the linear speed is high, the corresponding band saw blade will also have a high linear speed. The band saw blade with high linear speed is easy to be overloaded, causing it to be scrapped in advance, with low service life and high frequency of equipment shutdown and maintenance, which affects the production progress.

Embodiment 1

[0015] Embodiment one: if Figure 1~2 As shown, a multi-band saw driving mechanism includes a frame 100, and the frame 100 has a plurality of coaxially arranged upper pulleys 200 and lower pulleys 300 with increasing diameters, and the upper pulleys 200 and the lower pulleys A plurality of band saw blades 400 forming a multi-circle ring structure are set on the pulley 300, and a drive shaft 500 between the upper pulley and the lower pulley is installed on the frame 100, and a plurality of lower pulleys are set on the drive shaft 500. The pulleys are one-to-one corresponding to the pulley 600 with decreasing diameter. The direction of decreasing diameter of the pulley is consistent with the direction of decreasing diameter of the upper pulley or the lower pulley. The pulley 600 is connected with the corresponding lower pulley through the transmission belt 700. The pulley thus becomes the driving pulley to drive the band saw blade 400 to work; each upper pulley and lower pulley ...

Embodiment 2

[0021] Embodiment 2: Since the multi-band saw drive mechanism 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 set with a plurality of pulleys corresponding to one by one and with decreasing diameters, and the pulleys are connected to the corresponding upper pulleys through a transmission belt; The belt installation part of the belt has a belt groove on the belt installation part, and the diameter of the belt installation part of all the upper pulleys is the same.

[0022] A working method of the multi-band saw drive mechanism as described above, the drive shaft rotates and then drives each pulley on the drive shaft to rotate, the pulley drives the corresponding upper pulley or lower pulley to rotate through the transmission belt, and the pulley on the drive shaft The diameter decreases sequentially from fro...

Abstract

The invention relates to a multi-beltsaw drive mechanism and a working method thereof. The multi-beltsaw drive mechanism comprises a rack. The rack is provided with multiple upper belt wheels and lower belt wheels, wherein the upper belt wheels and the lower belt wheels are arranged coaxially, the diameters of the upper belt wheels and the lower belt wheels are increased gradually. Multiple beltsaw blades for forming a multi-circle ring-shaped structure are installed on the upper belt wheels and the lower belt wheels in a sleeving manner. The rack is provided with a drive rotating shaft located between the upper belt wheels and the lower belt wheels. Multiple belt wheels are installed on the drive rotating shaft in a sleeving manner, wherein the belt wheels correspond to the upper belt wheels or the lower belt wheels one to one, and the diameters of the belt wheels are reduced gradually. The belt wheels and the corresponding upper belt wheels or lower belt wheels are connected in a transmission manner through transmission belts. According to the multi-beltsaw drive mechanism, linear speeds of all the lower belt wheels can be consistent basically, it is ensured that all the beltsawblades can keep the consistent linear speeds to work, it is ensured that the service life of all the beltsaw blades tends to be consistent, the situation that due to the too high linear speed, the beltsaw blades on the belt wheels with the large diameters are scraped in advance, the shutdown overhaul frequency is reduced, the schedule of workpieces is ensured, and the economic benefits are increased.

Description

technical field [0001] The invention relates to a multi-band saw driving mechanism and its working method. Background technique [0002] The current multi-band saw mainly uses the lower pulley as the driving pulley, and the lower pulley adopts an integral structure or is set on the same drive shaft to rotate synchronously; because the lower pulley rotates at the same speed, this results in the pulley with a larger diameter The higher the linear speed, the higher the linear speed of the corresponding band saw blade. The band saw blade with higher linear speed is likely to be overloaded, causing it to be scrapped in advance, the service life is low, and the frequency of equipment shutdown and maintenance is high, which affects the production progress. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a multi-band saw driving mechanism and its working method that can reduce the linear speed difference between the multi-saw ...
