The conveyor belt is arranged along the sawing direction of the logs, and can transport the cut plates or curved side panels. The material holding device 2 is arranged behind the band saw machine 1, and can provide elastic force to press the plates on the logs that have been cut but not completely cut against the logs, and use a mechanical structure instead of manual material holding, which saves human resources and also reduces the hidden danger of the saw blade 12 injuring people. The side shift conveyor device 3 is arranged in the middle of the conveyor belt, which can lift the plates on the conveyor belt and move them to the outside of the conveyor belt, while the curved side panels flow along the conveyor belt to the end and then are transferred.

[0040] In particular, the transmission connection method adopted in the present application can be gear transmission, chain transmission or belt transmission, and can be flexibly configured according to actual site conditions.

When in use, the holding cylinder 24 pushes out the holding slide 22, so that the holding roller 27 enters above the conveyor belt; then, the band saw machine 1 uses the saw blade 12 to saw the log clamped on the carriage. As the carriage moves forward, the holding roller 27 comes into contact with the board material that has been cut but not completely cut off from the log, and through the support of the gas spring 25, the holding roller 27 will be tightly pressed against the board material. In this way, manual operation is replaced to hold the material, which saves human resources and can also prevent accidental injuries during the sawing process of the saw blade 12.

[0057] Working principle of the present invention:

[0058] See also Figure 1-14 When the automatic discharging conveyor line of the sports car band saw machine is working, first, after placing the log on the sports car, the sports car moves along the guide rail to the band saw machine 1, and the saw blade 12 starts to cut the log. At the same time, the holding device 2 starts to work, and the holding cylinder 24 pushes out the holding slide 22, so that the holding roller 27 is located above the front conveyor belt 4. Then, as the sports car moves forward and the log sawing work proceeds, the board material on the log that has been cut but not completely cut begins to contact the holding roller 27. Through the support of the gas spring 25, the holding roller 27 will press the board material tightly against the log, and the board material is pressed against the log to realize the holding work. After the log sawing is completed, the sports car resets through the track and prepares for the next round of sawing work, and the completely sawed board material falls onto the front conveyor belt 4 and the middle conveyor belt 5 under the action of its own gravity, moves forward through the rotation of the front roller 42 and the middle roller 52, and can be transported close to the edge through the roller spiral teeth 47.

[0059] When the curved side board is cut from the log, the lifting cylinder 35 of the side shift conveyor 3 does not work, and the conveyor platform 32 is still located below the middle roller 52; the swing cylinder 64 of the rear conveyor belt 6 does not work, and the upper end height of the limit plate 66 is still lower than the height of the rear roller 62. Therefore, the curved side board can pass through the middle conveyor belt 5 and the rear conveyor belt 6 normally, and after being conveyed to the end of the rear conveyor belt 6, it is moved away by the workers. Finally, all parts are reset and wait for the next round of work.

[0060] When the sheet material (square sheet material) cut from the log is cut, the swing cylinder 64 of the rear conveyor belt 6 works, the piston rod of the swing cylinder 64 extends, the limit plate 66 swings around the hinge shaft 65, the upper end of the limit plate 66 is higher than the rear roller 62, and the front end of the sheet material is blocked by the limit plate 66 and cannot move forward, and stays on the middle conveyor belt 5. Then, the lifting cylinder 35 of the side shift conveying device 3 works, the piston rod of the lifting cylinder 35 extends, driving the conveying platform 32 to rise in height, higher than the middle conveyor belt 5, and the sheet material staying on the middle conveyor belt 5 is lifted by the conveying sprocket 323 on the conveying platform 32 and leaves the middle conveyor belt 5. Then the power motor 36 works, driving the conveying sprocket 323 to work through the transmission action, and the sheet material on the conveying sprocket 323 is transported to the storage platform 33, and slides to the front of the supporting square tube 34 through the rolling cooperation with the storage bearing 331, and then is moved away by the workers or carried out the next processing work. Finally, all components are reset and ready for the next round of work.
