[0021] Example 1

[0022] See also Figure 1-3A transmission device for an automatic extrusion strapping machine comprises a first conveyor 1 and a second conveyor 5. A first conveyor roller 2 is arranged inside the first conveyor 1, a first conveyor belt 3 is arranged outside the first conveyor roller 2, a strapping mechanism 4 is arranged at the outer end of the first conveyor 1, a second conveyor roller 6 is arranged inside the second conveyor 5, a second conveyor belt 7 is arranged outside the second conveyor roller 6, cylinders 8 are fixed on both sides of the first conveyor 1, an arch frame 9 is fixed on the surface of the cylinder 8 push rod, a pressure roller 10 is arranged inside the arch frame 9, a driving gear 20 is fixed on the outer end of the first conveyor roller 2, a motor 21 is fixed on the outer end of the first conveyor 1, a driven gear 22 is fixed outside the driving shaft of the motor 21, a first pulley 24 is fixed outside the first conveyor roller 2 at the rear end of the first conveyor 1, and a second pulley 60 is fixed on the outer end of the second conveyor roller 6;

[0023] The first pulley 24 and the second pulley 60 are externally mounted with a transmission belt 100. The diameter of the first pulley 24 is larger than that of the second pulley 60. During transmission, when the first conveyor belt 3 rotates, the second conveyor belt 7 can be driven to rotate synchronously through the transmission belt 100. When the first pulley 24 is larger than the second pulley 60, the second conveyor belt 7 rotates faster than the first conveyor belt 3. When the second conveyor belt 7 is used to transport the bundle, the bundle can be spaced apart from the bundle on the first conveyor belt 3, and stacking and squeezing during transportation will not occur.

[0024] The driving gear 20 and the driven gear 22 are bevel gears, and the driving gear 20 and the driven gear 22 are meshed with each other. When driving, the motor 21 drives the driven gear 22 to rotate, which can drive the driving gear 20 to rotate, the first conveying roller 2 to rotate, and the first conveying belt 3 to rotate, which is convenient for controlling the drive;

[0025] The pressure roller 10 is arranged near the strapping mechanism 4, and the outer surface of the pressure roller 10 is covered with a rubber layer. When the strapping piece is transported into the strapping mechanism 4, the cylinder 8 can drive the arch frame 9 to descend, and the pressure roller 10 can be driven to squeeze the strapping piece from the upper end for transportation, and the squeezing positioning can be performed, so that the strapping will not deviate.

[0026] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto.
