DETAILED DESCRIPTION

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention in any way.

[0020] See attached Figures 1-4As shown, a dual servo belt conveyor includes a frame 1, on which two synchronous belts are arranged side by side, namely a first synchronous belt 4 and a second synchronous belt 5, and the first synchronous belt 4 and the second synchronous belt 5 together constitute a plane for conveying materials. A first servo motor 2 is arranged at one end of the frame 1 to drive the first synchronous belt 4 to move, and a second servo motor 3 is arranged at the other end of the frame 1 to drive the second synchronous belt 5 to move. A plurality of first fixed blocks 6 are arranged at intervals along the conveying direction of the first synchronous belt 4, and the length of the first fixed block 6 is equal to the sum of the widths of the first synchronous belt 4 and the second synchronous belt 5, and the first fixed block 6 is fixedly connected to the conveying surface of the first synchronous belt 4 by screws. A plurality of second fixed blocks 8 are arranged at intervals along the conveying direction of the second synchronous belt 5, and the length of the second fixed block 8 is equal to the sum of the widths of the first synchronous belt 4 and the second synchronous belt 5, and the second fixed block 8 is fixedly connected to the conveying surface of the second synchronous belt 5 by screws. The adjacent first fixed block 6 and second fixed block 8 form a positioning group. Multiple positioning groups are arranged along the synchronous belt. Each positioning group also includes two material clamping plates 7, which are respectively installed on the two opposite sides of the first fixed block 6 and the second fixed block 8, so that the plate surfaces of the two material clamping plates 7 are opposite to each other, so as to clamp the conveyed material.

[0021] When in use, the first synchronous belt 4 and the second synchronous belt 5 can be driven by the first servo motor 2 and the second servo motor 3 respectively, so the two servo motors can be controlled to move respectively, so as to adjust the distance between the two material clamping plates 7 in the same positioning group to clamp materials of different sizes and adjust the stop position. At the same time, the material clamping plates 7 are fixed on the synchronous belt to realize the clamping and conveying of the materials, so that no additional clamping action is required, and the beat of the conveyor can be improved.

[0022] Combine the following Figure 3 and Figure 4 , explaining the driving principle of the first servo motor 2 on the first synchronous belt 4 and the second servo motor 3 on the second synchronous belt 5. The first synchronous belt 4 is tensioned on the two first synchronous pulleys 10 at both ends of the frame 1, and the second synchronous belt 5 is tensioned on the two second synchronous pulleys 12 at both ends of the frame 1. The first synchronous pulley 10 and the second synchronous pulley 12 at the same end of the frame 1 are arranged concentrically.

[0023] like Figure 3As shown in the figure, at the first end of the frame 1, the first synchronous belt 4 is tensioned on the first synchronous pulley 10, and the second synchronous belt 5 is tensioned on the second synchronous pulley 12. The first synchronous pulley 10 is drivingly connected to the first transmission shaft 9 of the first servo motor 2 through a tensioning sleeve 11. A bearing 13 is installed between the second synchronous pulley 12 and the first transmission shaft 9. The inner ring of the bearing is connected to the first transmission shaft 9, and the outer ring of the bearing is connected to the second synchronous pulley 12. After the first servo motor 2 drives the first transmission shaft 9 to rotate, the first synchronous pulley 10 is driven to rotate, and the second synchronous pulley 12 cannot rotate. Therefore, the first servo motor 2 can drive the first synchronous belt 4 independently. Both ends of the first transmission shaft 9 are respectively supported on the bearing seats 14 on both sides of the frame 1.

[0024] As Figure 4 shown in the figure, at the second end of the frame 1, the first synchronous belt 4 is tensioned on the first synchronous pulley 10, and the second synchronous belt 5 is tensioned on the second synchronous pulley 12. The second synchronous pulley 12 is drivingly connected to the second transmission shaft 16 of the second servo motor 3 through a tensioning sleeve 11. A bearing 13 is installed between the first synchronous pulley 10 and the second transmission shaft 16. The inner ring of the bearing is connected to the second transmission shaft 16, and the outer ring of the bearing is connected to the first synchronous pulley 10. After the second servo motor 3 drives the second transmission shaft 16 to rotate, the second synchronous pulley 12 is driven to rotate, and the first synchronous pulley 10 cannot rotate. Therefore, the second servo motor 3 can drive the second synchronous belt 5 independently. Both ends of the second transmission shaft 16 are respectively supported on the bearing seats 14 on both sides of the frame 1.

[0025] The first servo motor 2 is connected to the first transmission shaft 9 by key connection to transmit torque. The second servo motor 3 is connected to the second transmission shaft 16 by key connection to transmit torque. The key connection can be a flat key connection or a spline key connection.

[0026] Based on the independent driving of the two synchronous belts by the two servo motors, the first servo motor 2 and the second servo motor 3 are respectively arranged on both sides of the frame 1.

[0027] Preferably, a tensioning assembly 15 is further arranged on one side of the first servo motor 2. The tensioning assembly 15 is used to adjust the position of the bearing seat 14 on which the first servo motor 2 is installed to tension the two synchronous belts. The tensioning assembly has the same structure as the tensioning assembly on a conventional belt conveyor.

[0028] The working process of the present utility model is as follows: 1. According to the size of the material, by starting the first servo motor 2 and the second servo motor 3 respectively, the distance between the first fixing block 6 and the second fixing block 8 on the synchronous belt is adjusted;

[0029] 2. Start the first servo motor 2 and the second servo motor 3 simultaneously, so that the first synchronous belt 4 and the second synchronous belt 5 move simultaneously, and convey the material between the two material clamping plates 7 forward;

[0030] 3. When reaching the predetermined position, turn off the first servo motor 2 and the second servo motor 3 simultaneously.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Those of ordinary skill in the art should understand that the specific implementation manners of the present invention can be modified or equivalently replaced by referring to the above embodiments. Any modification or equivalent replacement that does not depart from the spirit and scope of the present invention is within the scope of protection of the claims pending for approval.
