This creation is related to the sawing machine, especially the saw blade driving mechanism of the sawing machine.

Please refer to a conventional sawing machine 10 shown in FIG. 1 , which mainly includes a machine 11 . The machine 11 is provided with a motor 12 and a saw blade 13 . The drive shaft 122 of the motor 12 is sleeved with a first pulley 14 . A second pulley 15 is connected to one side of the saw blade 13, and the first and second pulleys 14, 15 are synchronously rotated by a transmission belt 16. Therefore, when the motor 12 is started, the first pulley 14 is driven to rotate first, and then the first pulley 14 drives the second pulley 15 to rotate through the transmission belt 16, so that the saw blade 13 can be driven to saw the workpiece.

In order to enable the transmission belt 16 to provide a stable power transmission effect, the motor 12 needs to be adjusted to match the relative positions between the first and second pulleys 14, 15 during installation, so that the first and second pulleys 14 and 15 are as far as possible. It can be kept on the same plane, but such a structural configuration is bound to cause the machine 11 to be too bulky and occupy too much use space. Therefore, the conventional sawing machine 10 does have a need for improvement.

The main purpose of the present invention is to provide a saw blade driving mechanism for a sawing machine, which can reduce the size of the sawing machine and save the use space of the sawing machine.

In order to achieve the above objectives, the blade driving mechanism of the present invention includes A drive unit, a sawing unit, and a transmission unit. The driving unit has a motor base, a motor, and a first pulley. The motor is disposed on the motor base and has a driving shaft. The first pulley is sleeved on the driving shaft of the motor, so that the first pulley can The driving shaft of the motor rotates synchronously; the sawing unit has a saw blade holder, a saw blade, and a second pulley. The saw blade is rotatably disposed on the saw blade holder by a rotating shaft, and the second pulley sleeve Provided on the rotating shaft, the second pulley can rotate synchronously with the rotating shaft of the saw blade; the transmission unit has a transmission shaft, a third pulley, a fourth pulley, a first transmission belt, and a second transmission belt The drive shaft is disposed in parallel with the drive shaft of the motor and the rotating shaft of the saw blade. The third and fourth pulleys are sleeved at two ends of the transmission shaft, and the first transmission belt is connected to the first and third ends. a pulley, the second transmission belt is connected to the second and fourth pulleys, so that the first and third pulleys and the second and fourth pulleys can pass through the transmission shaft to achieve the synchronous rotation effect.

Thereby, the structural configuration of the saw blade driving mechanism of the present invention can greatly reduce the volume of the sawing machine to save space.

Referring to FIG. 2, the sawing tool 20 shown in the drawing comprises a machine table 30 and a saw blade driving mechanism 40. The blade driving mechanism 40 of the present invention comprises a driving unit 50, a sawing unit 60, and a Transmission unit 70.

The drive unit 50 has a motor mount 52, a motor 54, and a first pulley 56. The motor base 52 is fixed in the machine base 30. The motor 54 fixes the motor base 52 and has a drive shaft 542. The first pulley 56 is sleeved on the drive shaft 542 of the motor 54, so that the first pulley 56 can be driven by the drive shaft 542 of the motor 54. Drive and turn.

The saw unit 60 has a blade holder 62, a saw blade 64, and a second pulley 66. The blade holder 62 is fixed in the machine table 30. The saw blade 64 is rotatably disposed on the blade holder 62 by a rotating shaft 642. The second pulley 66 is sleeved on the rotating shaft 642, so that the saw blade 64 and the second pulley 66 can be Rotate synchronously.

Referring to Figures 2 and 3, the transmission unit 70 has a transmission shaft 71 which is disposed in the motor base 52 in the manner of a drive shaft 542 of the parallel motor 54 and a rotation shaft 642 of the saw blade 64. Further, the transmission shaft 71 is provided. One end sleeve is provided with a third pulley 72. The third pulley 72 is aligned with the first pulley 56 of the driving unit 50 on the same plane, and the first pulley 56 is connected by a first transmission belt 73, so that the first and the third are made. The pulleys 56, 72 can be rotated synchronously. In addition, the other end of the transmission shaft 71 is sleeved with a fourth pulley 74. The fourth pulley 74 is aligned with the second pulley 66 of the sawing unit 60 on the same plane, and by a second The drive belt 75 is coupled to the second pulley 66 such that the second and fourth pulleys 66, 74 are synchronously rotatable.

It can be seen from the above that when the motor 54 is started, the first pulley 56 is synchronously driven to rotate, and then the first pulley 56 drives the third pulley 72 to rotate through the first transmission belt 73. At this time, the transmission shaft 71 is subjected to the third pulley 72. Driven together with the fourth pulley 74, the fourth pulley 74 will then drive the second pulley 66 through the second drive belt 75, thus driving the saw blade 64 is actuated to saw the workpiece.

In summary, the blade driving mechanism 40 of the present invention allows the motor 54 to be mounted without the special position of the saw blade 64 by the addition of the transmission unit 70. Compared with the conventional technology, the structure of the creation is configured. The machine 30 can be made lighter in size and save space.
