The deboning line requires weighing of the carcasses and segments before loading. Currently, the industry standard is to install a weighing mechanism on the conveyor feeding device to weigh the materials simultaneously with loading. However, existing integrated conveyor feeding devices with weighing mechanisms have the following shortcomings:

[0003] (1) The equipment has a high degree of integration and a tight and complex internal structure. The daily maintenance, repair and replacement of the functional structure requires high technical skills and the operation efficiency is low.

[0004] (2) The mechanical vibration generated by the drive motor affects the whole machine, greatly affects the data acquisition of the weighing equipment, and affects the accuracy of the weighing results. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the inconvenience of maintenance caused by the high integration and complex internal structure of existing integrated conveying and feeding devices, as well as the impact of the drive structure on the overall machine and its influence on the weighing results. This utility model provides a pre-bonding weighing and conveying feeding device, which is designed and assembled with independent modular structure according to function, making it easy to maintain and repair.

The drive mechanism includes a main motor and main shaft bearing mounted on both sides of the feeding line support, and a drive wheel axle with several drive sprockets mounted on it. The feeding conveying mechanism includes a pair of frame plates fixed to two symmetrical upper supports on both sides of the feeding line support, a bracket mounted between the two frame plates, several conveying wheel axles and a pair of tensioning wheel axles rotatably connected between the two frame plates via bearings, and driven sprockets corresponding to the positions of the drive sprockets on the conveying wheel axles.

[0007] Furthermore, the frame plate has an elongated slot, and spring telescopic guide rods and retaining rings are installed on both sides of the slot. The ends of the spring telescopic guide rods are fixed to the retaining rings, and the two ends of the tension wheel shaft are rotatably connected to the spring telescopic guide rods through bearings.

[0008] Furthermore, the bracket includes several base frame columns perpendicular to the conveying direction and horizontally supported on both side frame plates, and support rods fastened to each base frame column and parallel to the conveying direction.

[0009] Furthermore, the feeding line support is provided with a longitudinal limiting frame, and the top of the longitudinal limiting frame has a guide hole; the bottom of the frame plate is provided with a guide post that passes through the guide hole.

The weighing fixing component 22 is fixed at the four corners of the feeding line support 1, the outer end of each weighing sensor 21 is fixed to the weighing fixing component 22, and an upper support component 23 is installed on the inner end of each weighing sensor 21. The driving mechanism 3 includes a main motor 31 and a main shaft bearing 32 mounted on both sides of the feeding line support 1, and a drive wheel shaft 33, on which several drive sprockets 331 are mounted. The feeding and conveying mechanism 4 includes a pair of frame plates 41 fixed on two symmetrical upper support members 23 on both sides of the feeding line bracket 1, a bracket 42 installed between the two frame plates 41, a plurality of conveying wheel shafts 43 and a pair of tensioning wheel shafts 44 rotatably connected between the two frame plates 41 by bearings; the conveying wheel shafts 43 are provided with driven sprockets 431 corresponding to the position of the drive sprocket 331.

[0024] Implementation Method 2: like Figure 1 , 4 As shown, the frame plate 41 of this pre-bonding weighing and conveying feeding device has an elongated slot 411, and spring telescopic guide rods 412 and retaining rings 413 are installed on both sides of the slot 411. The ends of the spring telescopic guide rods 412 are fixed to the retaining rings 413, and the two ends of the tension wheel shaft 44 are rotatably connected to the spring telescopic guide rods 412 through bearings. A rectangular spring is installed inside the outer cylinder of the spring telescopic guide rod to push the guide rod out. The paired spring telescopic guide rods on both sides press the tension wheel axially inward onto the conveying chain to ensure the tension of the chain. To ensure the operation of the chain, a freely rotatable roller sleeve is installed on the tension wheel shaft. The remaining structures and components are as described in Embodiment 1 and will not be described again.

[0025] Implementation Method 3: like Figure 4 As shown, the bracket 42 of this pre-bonding weighing and conveying feeding device includes several base frame columns 421 perpendicular to the conveying direction and horizontally supported on the two side frame plates 41, and support rods 422 fastened to each base frame column 421 and parallel to the conveying direction. The support rods, chains, and materials are used for support. The remaining structures and components are as described in Embodiment 1 and will not be repeated.

[0026] Implementation Method 4: like Figure 1 , 4As shown, the feeding line support 1 of this pre-bonding weighing and conveying device is provided with a longitudinal limiting frame 11, and the top of the longitudinal limiting frame 11 has a guide hole 111; the bottom of the frame plate 41 is provided with a guide post 414 that passes through the guide hole 111.

The remaining structures and components are as described in Embodiment 1 and will not be repeated.

[0027] At runtime: The upstream conveyor belt transports the material (pork carcass) to one side of this unit. Driven by the main motor, the drive wheel axle, through drive and driven sprockets, causes the conveyor chain to transport the material on the conveyor wheel axle. The bracket supports the material during transport. During the transport process, each weighing sensor continuously collects the weight of the entire feeding conveyor mechanism and uploads the data to the host computer or controller for dynamic compensation data processing (subtracting the self-weight of the feeding conveyor and other noise, which is existing technology) and outputs the results. After weighing, the material is transported to the downstream deboning line conveyor mechanism of the production line. By forming the feeding conveyor mechanism, weighing mechanism, and drive mechanism into independent modules, maintenance, and replacement are facilitated. The feeding conveyor is suspended and the drive mechanism is independently mounted on the feeding line support, greatly reducing mechanical vibration interference with weighing.

[0028] This pre-bonding weighing and conveying device overcomes the inconvenience of maintenance caused by the high integration and complex internal structure of existing integrated conveying and conveying devices, as well as the impact of the drive structure on the overall machine and its influence on the weighing results. It adopts an independent modular design and assembly based on function, making it easy to maintain and repair. At the same time, the independent drive mechanism and the suspended installation of the conveying device greatly reduce the interference of mechanical vibration on the weighing.
