According to different uses, it can be divided into running wood band saw machine, re-splitting band saw machine and joinery band saw machine. Sports car band saw machine: sports car woodworking band saw machine uses sports car to carry wood back and forth to saw wood;

[0003] A cutting device is often required during the processing of wood, and the cutting device needs to fix the wood before processing. The current common fixing method is to set limit plates on both sides of the wood, and adjust the distance between the limit plates by screws to clamp the wood. Although the fixing effect is good, the screws need to be adjusted many times during the clamping and loosening of the wood. Since the same wood needs to be processed many times, not only the processing time of the wood is wasted, but frequent adjustment of the screws may also cause the screws to slip and lose their effect. Therefore, the utility model proposes a feeding and discharging conveyor line structure of a sports car band saw machine to solve the above problems. Utility Model Content

[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a feeding and discharging conveyor line structure for a sports car band saw machine, including a box body 1, a support frame 2 and a limit plate 3. The bottom of the box body 1 is provided with a support frame 2, and the bottom of the support frame 2 is symmetrically rotatably connected with a rotating shaft 5, and both ends of the rotating shaft 5 are fixedly connected with rollers 11. The bottom of the support frame 2 is provided with a driving mechanism, and one side of the box body 1 is provided with a limit plate 3. The box body 1 is provided with a fixing mechanism matching the limit plate 3, and the wood is fixed to the bottom of the limit plate 3 through the fixing mechanism, and then the driving mechanism drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the roller 11 to rotate, and the roller 11 drives the entire device to move, so that the wood automatically moves toward the saw blade of the band saw machine, and then the wood is automatically cut into wooden boards.

[0020] The fixing mechanism includes a movable claw 4, a wedge block 6, a guide rail 7, a No. 1 hydraulic cylinder 8, a connecting rod 9 and a fixing frame 10. The movable claw 4 is hinged inside the box body 1, and a fixing frame 10 is fixed on the top of the box body 1. The No. 1 hydraulic cylinder 8 is installed on the top of the fixing frame 10. The output end of the No. 1 hydraulic cylinder 8 is connected to the wedge block 6 through the connecting rod 9. The wedge block 6 is slidably connected to the inner wall of the box body 1 through the guide rail 7. The shape of the movable claw 4 is set to be "L" shaped. One end of the movable claw 4 is provided with an arc surface that matches the inclined surface of the wedge block 6. The wood is placed on the movable claw 4. On the top, because the wedge block 6 is connected to the output end of the No. 1 hydraulic cylinder 8, the No. 1 hydraulic cylinder 8 can drive the wedge block 6 to move downward, so that the inclined surface on one side of the wedge block 6 squeezes the movable claw 4, and then drives the movable claw 4 to rotate clockwise, and the movable claw 4 cooperates with the limiting plate 3 to clamp the wood to fix the wood on one side of the box body 1. When the wood needs to be removed, the No. 1 hydraulic cylinder 8 drives the wedge block 6 to move upward, the wedge block 6 no longer squeezes the movable claw 4, and the movable claw 4 is driven to rotate counterclockwise by gravity, the distance between the movable claw 4 and the limiting plate 3 increases, and the wood automatically rolls down.

[0021] A tightening mechanism is provided below the limiting plate 3, and the tightening mechanism includes a telescopic rod 19, a clamping block 20 and a spring 21. Two telescopic rods 19 are connected to one side of the box body 1, and a clamping block 20 is provided at one end of the two telescopic rods 19. An arc groove is provided on one side of the clamping block 20, and a spring 21 is provided on the outer side of the telescopic rod 19. After the movable claw 4 squeezes one side of the wood and contacts the arc surface on the clamping block 20, it will drive the telescopic rod 19 and the spring 21 to shrink inward, and the elastic force generated by the spring 21 is used to drive the clamping block 20 to move in the direction of the wood, so that after the movable claw 4 and the limiting plate 3 clamp the wood, the wood is tightened by the clamping block 20, which facilitates the wood to be fixed more stably.

[0022] A slide rail 13 is installed on the top of the support frame 2, and the bottom of the box body 1 is slidably connected to the inside of the support frame 2. A No. 2 hydraulic cylinder 12 is installed on one side of the top of the support frame 2, and the output end of the No. 2 hydraulic cylinder 12 is connected to the side of the box body 1 away from the limit plate 3. Since one side of the box body 1 is connected to the output end of the No. 2 hydraulic cylinder 12, the No. 2 hydraulic cylinder 12 can drive the box body 1 to slide horizontally back and forth on the slide rail 13, so that the distance between the wood and the saw blade can be adjusted, so as to adjust the thickness of the wood and continuously cut the wood into pieces.

[0023] The driving mechanism includes a motor 14, a driving shaft 15, a first gear 16 and a second gear 17. The motor 14 is installed at the bottom of the support frame 2, and the driving shaft 15 is rotatably connected to the bottom of the support frame 2. The first gear 16 is fixed to both ends of the driving shaft 15, and the second gear 17 is fixed to the outside of the rotating shaft 5. The output end of the motor 14 is fixedly connected to one end of the driving shaft 15 through a coupling, and the outer wall of the first gear 16 and the outer wall of the second gear 17 are meshed with each other. An electric hydraulic brake 18 is installed at the bottom of the support frame 2, and one end of the driving shaft 15 passes through the interior of the electric hydraulic brake 18. Since one end of the driving shaft 15 is connected to the output end of the motor 14, the motor 14 can drive the driving shaft 15 to rotate at the bottom of the support frame 2. The wheel 16 is connected to the driving shaft 15, and the No. 1 gear 16 and the No. 2 gear 17 are meshed with each other, and the No. 2 gear 17 is connected to the rotating shaft 5, so that the motor 14 can drive the two rotating shafts 5 to rotate at the same time, and the roller 11 is connected to the rotating shaft 5, which can drive the four rollers 11 to rotate at the same time, thereby driving the entire box 1 to move horizontally, and the forward direction is controlled by the rotation direction of the motor 14. An electric hydraulic brake 18 is installed at the bottom of the support frame 2, and the brake block is opened through the hydraulic transmission mechanism, pressing the inner surface of the brake wheel to tighten the brake, so that the driving shaft 15 stops rotating, which is used to stop the rotation of the roller 11 in an emergency, and drive the entire device to stop moving, so as to ensure the safety of the cutting work. When it is necessary to continue working, the hydraulic transmission mechanism drives the brake block to reset, releases the brake wheel and releases the brake.

[0024] The feeding and discharging conveyor line structure of the sports car band saw machine places the wood on the movable claw 4. Because the wedge block 6 is connected to the output end of the No. 1 hydraulic cylinder 8, the No. 1 hydraulic cylinder 8 can drive the wedge block 6 to move downward, so that the inclined surface on one side of the wedge block 6 squeezes the movable claw 4, and then drives the movable claw 4 to rotate clockwise. The movable claw 4 cooperates with the limit plate 3 to clamp the wood to fix the wood on one side of the box body 1. When the wood needs to be removed, the No. 1 hydraulic cylinder 8 drives the wedge block 6 to move upward, and the wedge block 6 no longer squeezes the movable claw 4. The movable claw 4 is driven to rotate counterclockwise by gravity, and the distance between the movable claw 4 and the limit plate 3 increases, and the wood automatically rolls down.
