[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0025] A weighing roller conveyor, such as Figures 1 to 5 As shown, the device includes two first conveying mechanisms 1, with a second conveying mechanism 7 disposed between the two first conveying mechanisms 1. The second conveying mechanism 7 includes two second housings 702, with multiple second conveying rollers 701 rotatably disposed between the two second housings 702. A support plate 8 is disposed at the bottom of the second conveying rollers 701, and an electric push rod 9 is fixedly connected to the top of the support plate 8. A connecting frame 10 is fixedly connected to the piston rod of the electric push rod 9. The top two ends of the connecting frame 10 are fixedly connected between the two second housings 702, respectively. Multiple uprights 13 are fixedly connected to the top of the support plate 8, and the same support platform 14 is fixedly connected to the top of the multiple uprights 13. A weighing platform 15 is fixedly connected to the top of the support platform 14, and multiple weighing plates 16 are fixedly connected to the top of the weighing platform 15. The weighing plates 16 are located between the multiple second conveying rollers 701.

[0026] like Figures 3 to 5 As shown, two movable rods 12 are fixedly connected to the bottom of the connecting frame 10, and two movable sleeves 11 are fixedly connected to the top of the support plate 8. The movable rods 12 are inserted into the movable sleeves 11, and the stability of the connecting frame 10 is increased through the movable rods 12 and the movable sleeves 11. The second conveying mechanism 7 also includes a plurality of second transmission rods 704 rotatably connected to the inner walls of both ends of one of the second housings 702. The second transmission rods 704 are fixedly arranged with the second conveying rollers 701. Two second transmission grooves 705 are opened on the outer wall of the second transmission rods 704. The two adjacent grooves are connected to the second transmission rollers 701. A second transmission belt 706 is connected between the second transmission rods 704. The second transmission belt 706 is located in the second transmission groove 705. A second motor 703 is fixedly connected to the outer wall of one end of another second housing 702. The output shaft of the second motor 703 is fixedly arranged with one of the second conveying rollers 701. The second motor 703 drives one of the second conveying rollers 701 to rotate. Under the action of the second transmission belt 706, multiple second transmission rods 704 are driven to rotate synchronously, thereby driving multiple second conveying rollers 701 to rotate synchronously and transport goods.

[0027] like Figure 1 and Figure 2As shown, the tops of the two second housings 702 are fixedly connected to the same gantry frame 4, and a camera 5 is fixedly installed on the top of the gantry frame 4. The status of the goods can be observed through the camera 5. The first conveying mechanism 1 includes two first housings 102, and multiple first conveying rollers 101 are rotatably connected between the two first housings 102. Multiple first transmission rods 104 are rotatably connected to the inner walls of both ends of one of the first housings 102. The first transmission rods 104 are fixedly arranged with the first conveying rollers 101. Two first transmission grooves 105 are opened on the outer wall of the first transmission rods 104. A first transmission belt 106 is connected between two adjacent first transmission rods 104. The first transmission belt 106 is located in the first transmission groove 105. A first motor 103 is fixedly connected to the outer wall of one end of the other first housing 102. The output shaft of a motor 103 is fixedly connected to one of the first conveying rollers 101. Multiple support legs 6 are fixedly installed at the bottom of the two first housings 102. A support plate 8 is fixedly connected between the multiple support legs 6. The first motor 103 drives one of the first conveying rollers 101 to rotate. Under the action of the first transmission belt 106, multiple first transmission rods 104 are driven to rotate synchronously, thereby driving multiple first conveying rollers 101 to rotate synchronously to transport goods. A support rod 3 is fixedly connected to the top of one of the first housings 102. A control panel 2 is fixedly connected to one end of the support rod 3. The control panel 2 is equipped with a buzzer 201, multiple control buttons 202, multiple indicator lights 203 and a display screen 204. The buzzer 201 can sound an alarm when the weight of the goods is not up to standard.

[0028] In Example 1, during operation, the first motor drive 103 drives one of the first conveyor rollers 101 to rotate. Under the action of the first transmission belt 106, multiple first transmission rods 104 are driven to rotate synchronously, thereby driving multiple first conveyor rollers 101 to rotate synchronously. The operator places goods onto the first conveyor rollers 101 in sequence for transport. When the goods are transported to the second conveyor roller 701, the second motor 703 drives the second conveyor roller 701 to rotate, so that the goods are positioned on the second conveyor roller 701. The length of the goods is the same as the length of the second housing 702. At this time, the second motor 703 stops working, and the electric push rod 9 drives the two second housings. As the body 702 moves downward, the second conveyor roller 701 moves downward until the weighing plate 16 passes through the second conveyor roller 701 and supports the goods. At this time, the weight of the goods is measured and recorded by the weighing platform 15. The weighing platform 15 is equipped with a pressure sensor, which can accurately weigh the goods. When the weight of the goods is not up to standard, an alarm is triggered by the buzzer 201. After the measurement is completed, the electric push rod 9 drives the second housing 702 to move upward and reset. The second motor 703 runs and transports the goods to the first conveying mechanism 1 on the other side. This ensures that the goods are stationary each time they are inspected, thereby ensuring the accuracy of the goods inspection. Example 2

[0029] Example 2 is based on Example 1, such as... Figure 6 As shown, the same guide block 17 is fixedly installed at both ends of the two second housings 702, and the side of the guide block 17 close to the second conveying mechanism 7 is inclined; the inclined surfaces of the two guide blocks 17 are provided with mounting grooves 18, and multiple rotating rods 19 are rotatably connected to the inner walls of both ends of the mounting grooves 18.

[0030] In Example 2, since the length of the cargo is the same as that of the second housing 702, the cargo can be moved to the middle of the second conveying mechanism 7 by gravity through the inclined surfaces of the guide blocks 17 on both sides, which further increases the accuracy of the measurement. The friction between the cargo and the guide blocks 17 is reduced by rotating the rod 19, which facilitates the movement of the cargo.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
