Description

Technical Field

[0001] The utility model particularly relates to a mis-packaging prevention packaging device for heavy-weight products. Background Art

[0002] Some heavy-weight products have many models, and operators cannot tell the difference from the appearance. For example, there are many models of roller ring products. There may be more than 20 models of roller rings produced on the production line at the same time. Different models of roller rings correspond to different steel bar rolling racks of end customers. Usually, operators will weigh the weight of a certain model of heavy-weight products by weighing, and judge whether the heavy-weight product is qualified based on the weight. For example, the Chinese patent with application number 202022327874.1 discloses an automatic weighing and error-proofing device, which judges whether the product is qualified by weighing.

[0003] However, some heavy products are heavy and it is difficult to pack them manually after weighing. Although the above patent solution can be used to weigh the products, it is impossible to pack the heavy products after weighing. Utility Model Content

[0004] The utility model aims to provide a large-weight product mis-packaging prevention packaging device which can carry out subsequent packaging of the large-weight product.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a heavy-weight product weighing and packaging equipment, including a conveying station, a weighing station and a packaging station, the conveying station includes a conveying roller, the weighing station includes a weighing platform, the weighing platform is located on the conveying roller, the weighing platform is equipped with a first lifting component, and the weighing platform can extend upward to above the conveying roller or descend to be flush with the conveying roller or below the conveying roller under the action of the first lifting component; the packaging station includes a clamping component located above the conveying roller, the clamping component can transport the packaging box to the top of the weighing platform and put the packaging box on the heavy-weight product workpiece; the packaging station also includes a first conveyor belt, the first conveyor belt is located in the transportation direction of the conveying roller and is used to receive the heavy-weight product workpiece with the packaging box, and a cover plate for sealing the packaging box is placed on the first conveyor belt.

[0006] During the operation of this scheme, the heavy-weight product workpiece is conveyed on the conveyor roller. When the heavy-weight product workpiece is transported to the position of the weighing platform, the weighing platform will rise and weigh the heavy-weight product workpiece. If it does not meet the standards, the operator can remove the heavy-weight product through the existing sling or clamp; if the weight of the heavy-weight product meets the standards of the model, the clamping component will transport the packaging box to the top of the weighing platform and put the packaging box on the heavy-weight product workpiece. Then the weighing platform will drop to be flush with the conveyor roller or below it so that the conveyor roller can continue to transport the heavy-weight product workpiece. After the heavy-weight product workpiece is transported to the first conveyor belt, the heavy-weight product will be supported on the cover plate. Finally, the operator will fix the packaging box and the cover plate together, thereby completing the model calibration and packaging of the heavy-weight product.
