[0034] The working principle and use process of the utility model: when the weighing and conveying mechanism of the baler is in use, the main bracket 101 first contacts the installation position on the baler, and the weighing and conveying mechanism body 100 is fixed to the baler for weighing and conveying. When the weighing and conveying mechanism body 100 is in use, the motor 104 drives the rotating roller 103 to rotate, and the rotating roller 103 drives the conveyor belt 105 to convey. At this time, the object is conveyed on the surface of the conveyor belt 105 and is weighed by the weighing device 102, so that the object is weighed and conveyed to the baling position of the baler for packaging.

[0035] Then, when the weighing conveying mechanism body 100 frequently conveys objects and causes the conveyor belt 105 to become loose, the clamping rod can be clamped on the outer surface of the rotating wheel 1050 at the end of the mounting plate 106 to drive the rotating wheel 1050 and the rotating rod 1059 to rotate. The rotating rod 1059 rotates to drive the torsion gear 2 1058 to engage with the torsion gear 1 1057 to rotate the screw rod 1053. When the screw rods 1053 at both ends rotate at the same time, the moving head 1055 moves on the outer surface of the screw rod 1053. The moving head 1055 When moving, the slide seat 1056 is driven to slide and control on the outer surface of the slide rail 1054, so that the two moving heads 1055 are moved at the same time to drive the connecting rod 1052 and the tensioning roller 1051 to move down and press tightly on the inner surface of the conveyor belt 105 to tighten the conveyor belt 105, which is convenient for adjusting the tension of the conveyor belt 105, so that the rotating roller 103 drives the conveyor belt 105 to rotate stably and not easy to slip, thereby improving the convenience of adjusting the tension of the conveyor belt 105 and the stability of transportation when the weighing and conveying mechanism body 100 is installed on the baler for use;

[0036] Finally, after the tension of the weighing and conveying mechanism main body 100 is adjusted before use, when the rotating wheel 1050 is in a certain position, the nut 1075 is rotated and screwed in to drive the threaded adjustment rod 1074 to screw in and move. When the threaded adjustment rod 1074 screws in and moves, it drives the clamping head 1072 to move inside the movable groove 1073 until the clamping head 1072 is engaged with the inside of the fixed clamping hole 1071 to fix the rotating wheel 1050, thereby fixing the rotating wheel 1050 and the rotating rod 1059, so that the weighing and conveying mechanism main body 100 is not likely to cause the rotating rod 1059 and the screw rod 1053 to rotate when vibrating during use, and the connecting rod 1052 and the tensioning roller 1051 are fixed to support the tensioning operation of the conveyor belt 105, thereby improving the installation of the weighing and conveying mechanism main body 100 on the baler, and strengthening the fixation of the connecting rod 1052 after the tension of the conveyor belt 105 is adjusted, and stabilizing the tensioning support.
