Detailed implementation manners

[0021] The following further describes the present application in detail Figures 1-4 with reference to the accompanying drawings.

[0022] An embodiment of the present application discloses an adjustable conveyor.

[0023] Referring to Figure 1 and Figure 2 , the adjustable conveyor includes a mounting frame 1, a mounting seat 2 is arranged on the mounting frame 1, a conveying device for conveying the material 21 is arranged on the mounting seat 2, and a lifting device for driving the mounting seat 2 to lift is arranged on the mounting frame 1. Therefore, when the material 21 from the previous process is conveyed onto the conveying device, if there is a height difference between the conveying device and the discharge end of the previous process, the lifting device is started to adjust the height of the mounting seat 2, thereby eliminating the height difference between the conveying device and the previous process, reducing the possibility of the stacked material 21 scattered due to the height difference, and improving the conveying efficiency of the material 21.

[0024] Referring to Figure 1 and Figure 2, the lifting device includes a lifting lead screw 3 rotatably connected to the mounting frame 1. In the embodiment of the present application, the lifting lead screw 3 is vertically arranged. A first driving motor 4 for driving the rotation of the lifting lead screw 3 is bolted to the top of the mounting frame 1, and the mounting seat 2 is arranged on the nut of the lifting lead screw 3. Therefore, when the first driving motor 4 is started, the lifting lead screw 3 at the output end of the first driving motor 4 is driven to rotate, thereby driving the mounting seat 2 to move along the direction of the lead screw, realizing the lifting of the mounting seat 2. While being more flexible, it is convenient to adjust the height of the mounting seat 2.

[0025] Refer to Figure 1 and Figure 2 , two guide rails 5 parallel to the lifting lead screw 3 are bolted to the mounting frame 1. The lifting lead screw 3 is located between the two guide rails 5. A slider 6 matching the size of the guide rail 5 is slidably connected to the guide rail 5, and the mounting seat 2 is arranged on the slider 6. Therefore, the guide rail 5 plays a role in limiting the sliding direction of the slider 6, reducing the possibility of the slider 6 offsetting during the sliding process, and improving the stability of the lifting process of the conveying device on the mounting seat 2.

[0026] Refer to Figure 1 and Figure 2 , the conveying device includes two conveying frames 7 arranged on the mounting seat 2. In the embodiment of the present application, the two conveying frames 7 are arranged oppositely. A driving wheel 8 and a driven wheel 9 are respectively rotatably connected to the two conveying frames 7. A conveyor belt 10 is tensioned and wound between the driving wheel 8 and the driven wheel 9. The material 21 is located between the two conveying frames 7 and is supported on the two conveyor belts 10. A driving unit for driving the two driving wheels 8 to rotate simultaneously is arranged on the mounting seat 2. Therefore, when the driving unit is started, the driving wheel 8 at the output end of the driving unit is driven to rotate, thereby driving the driven wheel 9 and the conveyor belt 10 to rotate synchronously, realizing the conveyance of the material 21, and conveying the stacked materials 21 from the previous process to the next process.

[0027] Refer to Figure 1 and Figure 2 , the driving unit includes two spline seats 11 bolted to the mounting seat 2. A spline shaft 12 is rotatably connected between the two spline seats 11. The spline shaft 12 is parallel to the mounting seat 2 and is perpendicular to the conveying direction of the conveyor belt 10. A second driving motor 13 for driving the rotation of the spline shaft 12 is mounted on the mounting seat 2. The second driving motor 13 is connected to the spline shaft 12 through a connecting component. Connecting seats 14 are respectively bolted to the two conveying frames 7. Spline wheels 15 matching the size of the spline shaft 12 are respectively rotatably connected to the two connecting seats 14. In the embodiment of the present application, the spline wheels 15 are located between the driving wheel 8 and the driven wheel 9. The spline shaft 12 passes through the two spline wheels 15, and the two conveyor belts 10 are respectively tensioned and wound around the outer edges of the two spline wheels 15.

[0028] Therefore, start the second drive motor 13. The spline shaft 12 rotates to drive the spline wheel 15 to rotate. Since the conveyor belt 10 is tensioned and wound around the driving wheel 8, the spline wheel 15, and the driven wheel 9, the spline wheel 15 can drive the driving wheel 8 to rotate, realizing the conveyance of the material 21 by the conveyor belt 10 and improving the conveyance efficiency of the material 21.

[0029] Refer to Figure 1 and Figure 2 The connecting assembly includes a first transmission wheel 16 arranged at the output end of the second drive motor 13. A second transmission wheel 17 is fixedly sleeved at one end of the spline shaft 12. A transmission belt 18 is tensioned and wound between the first transmission wheel 16 and the second transmission wheel 17. Therefore, start the second drive motor 13 to drive the first transmission wheel 16 at the output end of the second drive motor 13 to rotate, so that the transmission belt 18 and the second transmission wheel 17 rotate synchronously, thereby realizing the rotation of the spline shaft 12. Using the driving method of the first transmission wheel 16, the second transmission wheel 17, and the transmission belt 18 saves the practical space occupied by the connecting assembly and improves the space utilization rate.

[0030] Refer to Figure 1 and Figure 2 On two conveying frames 7, telescopic cylinders 29 are respectively connected by bolts. The output ends of two oppositely arranged telescopic cylinders 29 are connected with profiling blocks 30. When the two telescopic cylinders 29 drive the profiling blocks 30 to extend, the material 21 is pressed tightly between the two profiling blocks 30, realizing the regularization of the position of the material 21 on the conveyor belt 10, reducing the possibility of the stacked material 21 shifting in position on the conveyor belt 10, and improving the stability of the conveyor belt 10 when conveying the material 21.

[0031] Refer to Figure 3 and Figure 4 On two conveying frames 7, sliding grooves 25 are respectively formed oppositely. Mounting columns 26 are respectively slidably connected in the two sliding grooves 25. Tensioning wheels 27 are respectively rotatably connected to the outer edges of the two mounting columns 26. Two conveyor belts 10 are respectively tensioned and wound around the outer edges of the two tensioning wheels 27. In the embodiment of the present application, the tensioning wheels 27 are located between the spline wheel 15 and the driven wheel 9 and are located between the driving wheel 8 and the spline wheel 15 in the height direction. Positioning units for fixing the positions of the mounting columns 26 are respectively arranged on two conveying frames 7. Therefore, the tensioning wheels 27 are used to adjust the tension degree of the conveyor belt 10. By adjusting the positions of the tensioning wheels 27, it is ensured that the sag of the conveyor belt 10 between the driving wheel 8 and the driven wheel 9 remains within a suitable range, so that the conveyor belt 10 can maintain an appropriate tension during operation, avoiding the conveyor belt 10 slipping due to insufficient tension or excessive wear of the conveyor belt 10 due to excessive tension, and improving the transmission efficiency of the conveyor belt 10.

[0032] Refer to Figure 2 and Figure 3, the positioning unit includes a sliding block 28 that matches the sliding groove 25. The sliding block 28 is slidably connected within the sliding groove 25. One end of the mounting post 26 facing the sliding block 28 passes through the sliding block 28 and is threadedly connected to the sliding block 28. One end of the mounting post 26 facing the conveying frame 7 abuts against the bottom of the sliding groove 25. When the mounting post 26 slides along the sliding groove 25 to adjust the tensioning wheel 27 to a proper position so that the tension of the conveyor belt 10 is within a proper range, rotate the mounting post 26 to make one end of the mounting post 26 facing the sliding groove 25 abut against the bottom of the sliding groove 25, reducing the possibility of the position deviation of the tensioning wheel 27 during the movement of the conveyor belt 10 and improving the stability of the position of the mounting post 26.

[0033] Refer to Figure 2 and Figure 3 , two adjusting seats 19 are bolted to the mounting seat 2. A double-nut screw rod 20 is rotatably connected between the two adjusting seats 19. In the embodiment of the present application, the double-nut screw rod 20 is specifically a bidirectional screw rod, and the moving positions of the two nuts of the double-nut screw rod 20 are opposite. A third driving motor for driving the double-nut screw rod 20 to rotate is provided on the mounting seat 2. The two conveying frames 7 are respectively arranged on the two nuts of the double-nut screw rod 20, and both of the two conveying frames 7 are slidably connected to the mounting seat 2. Therefore, when the third driving motor is started, the double-nut screw rod 20 at the output end of the third driving motor rotates, causing the positions of the two nuts of the double-nut screw rod 20 to move relatively along the length direction of the double-nut screw rod 20, thereby realizing the adjustable width position between the two conveying frames 7, enhancing the flexibility and improving the applicable range of the adjustable conveyor at the same time.

[0034] Refer to Figure 2 and Figure 3 , two stabilizing seats 22 are bolted to the mounting seat 2. A stabilizing rod 23 is arranged between the two stabilizing seats 22. In the embodiment of the present application, the stabilizing rod 23, the double-nut screw rod 20, and the spline shaft 12 are arranged parallel to each other. The double-nut screw rod 20 is located between the stabilizing rod 23 and the spline shaft 12. Stabilizing blocks 24 are respectively bolted to the two conveying frames 7. The stabilizing rod 23 passes through the two stabilizing blocks 24 and the two stabilizing blocks 24 are slidably connected to the stabilizing rod 23. Therefore, when the width position between the two conveying frames 7 changes, the stabilizing blocks 24 slide along the direction of the stabilizing rod 23 as the position of the conveying frame 7 changes, further improving the stability of the movement of the two conveying frames 7 through the stabilizing rod 23.

[0035] The implementation principle of the embodiment of this application is as follows: When the material 21 in the previous process is conveyed onto the conveying device, if there is a height difference between the conveying device and the discharge end of the previous process, the first driving motor 4 is started to drive the lifting lead screw 3 at the output end of the first driving motor 4 to rotate, thereby driving the mounting seat 2 to move along the direction of the lead screw, realizing the lifting of the mounting seat 2; When it is necessary to adjust the distance between the two conveying frames 7, the third driving motor is started, and the double-nut lead screw 20 at the output end of the third driving motor rotates, causing the two nuts of the double-nut lead screw 20 to move along the length direction of the double-nut lead screw 20, thereby realizing the adjustable width position between the two conveying frames 7; The second driving motor 13 is started to drive the first transmission wheel 16 at the output end of the second driving motor 13 to rotate, causing the transmission belt 18 and the second transmission wheel 17 to rotate synchronously, thereby realizing the rotation of the spline shaft 12. The rotation of the spline shaft 12 drives the spline wheel 15 to rotate. Since the conveyor belt 10 is tensioned and wound between the driving wheel 8, the spline wheel 15 and the driven wheel 9, the spline wheel 15 can drive the driving wheel 8 to rotate, realizing the conveyance of the material 21 by the conveyor belt 10, and conveying the stacked material 21 on the conveyor belt 10 to the next process. The lifting device is used to eliminate the height difference between the conveying device and the previous process, reduce the possibility of the stacked material 21 falling due to the height difference, and improve the conveying efficiency of the material 21.
