[0022] Any feature disclosed in this specification, unless stated otherwise, can be replaced by alternative features or equivalents having the same or a similar effect. That is, unless stated otherwise, each feature is one example only of a number of alternative or equivalent features.

[0023] As shown in Figure 1 , Figure 2 and Figure 3 , the high-precision automatic weighing equipment of the present application comprises an inner support plate 1 and a conveying belt 2, the conveying belt 2 is sleeved on the outside of the inner support plate 1, a groove 5 is recessed on the inner support plate 1, an electronic scale 6 is arranged in the groove 5, the outer ring of the inner support plate 1 is not in contact with the inner ring of the conveying belt 2, support rings 4 are installed on the outer ring of the inner support plate 1 near the edges, the outer ring surface of the support rings 4 is in contact with the inner ring surface of the conveying belt 2, and a plurality of rectangular ports 3 for conveying the objects to be weighed are arranged in a ring structure on the outer ring surface of the conveying belt 2.

[0024] In this embodiment, a plurality of fixed plates 12 are installed on both sides of the inner support plate 1 in the length direction, limiting plates 7 are arranged on the outer sides of the fixed plates 12, a limiting passage matching the width of the conveying belt 2 is formed between the limiting plates 7, the conveying belt 2 is arranged in the limiting passage, screw holes are arranged in the middle of the fixed plates 12, fixed holes are arranged opposite the screw holes, and bolts for locking and fixing the limiting plates 7 on the fixed plates 12 are threadedly connected in the opposite screw holes and fixed holes;

[0025] After the screws are removed, the limiting plates can be disassembled, at which time the conveying belt can be removed from the support rings longitudinally, facilitating replacement of the conveying belt.

[0026] In this embodiment, the inner support plate 1 is provided with mounting ports at both ends, and the mounting ports are respectively provided with driving rollers 8 and driven rollers 10 which are in contact with the inner ring of the conveying belt 2. The inner support plate 1 is provided with fixing seats 9 on both sides of the driving rollers 8 and the driven rollers 10, and the fixing seats 9 are respectively provided with bearings. The roller shafts of the driving rollers 8 and the driven rollers 10 are respectively arranged in the inner ring of the bearings. The fixing seat 9 on the side of the driving roller 8 is provided with a motor which is connected with the driving roller 8.

[0027] In this embodiment, the surface of the weighing platform of the electronic scale 6 is flush with the top surface of the inner support plate 1, so that the brake pad can be smoothly pushed to the surface of the electronic scale.

[0028] In this embodiment, the inner support plate 1 is made of metal material, which increases the firmness.

[0029] In this embodiment, the inner support plate 1 is arranged in a ring structure, so as to support the inside of the conveying belt and avoid the inward bending of the conveying belt.

[0030] In this embodiment, the electronic scale 6 is fixed by screws arranged on both sides of the groove body 5. The weighing platform of the electronic scale 6 is not in contact with the inner side surface of the groove body 5. The electronic scale can be fixed by the screws, so as to avoid the displacement of the weighing quality. After the screws are removed, the electronic scale can be directly taken out, which facilitates the replacement of the electronic scale.

[0033] In use, the worker at the feeding station puts the brake pad into the rectangular port. The rotation of the driving roller is driven by the motor. The driving roller drives the conveying belt to rotate along the support ring. The brake pad is pushed to the electronic scale by the rotating conveying belt. Since the inner ring of the conveying belt is not in contact with the electronic scale, the weighing quality is not affected. The motor is in a stop-start mode, so that the conveying belt is stopped immediately after the brake pad moves to the surface of the electronic scale, so as to avoid the influence on the detection quality. After the detection, the conveying belt is rotated again, so as to push the brake pad after the weighing away. The subsequent brake pad is sequentially pushed to the electronic scale.

[0034] In the weighing process, the worker at the weighing station only needs to check whether the weight meets the requirements. The unqualified product can be directly taken out, and the qualified product after the weighing can be moved to another station, so as to ensure the orderliness of the operation.

[0035] The support ring and the inner support plate are arranged in the inside of the conveying belt, a large number of rollers are not needed, the overall structure is simple, and the cost is reduced.

[0036] The above merely describes a specific implementation of the present application, but the protection scope of the present application is not limited thereto, any change or replacement without creative labor should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be limited by the protection scope defined in the claims.
