Description

Technical Field

[0001] This utility model belongs to the field of copper and copper processing, and specifically relates to an online weighing and handling device for small-sized copper strip coils. Background Technology

[0002] For the production process of copper and copper alloy strips, according to the requirements of the user industries, most copper strips are slit into strips by slitting machines for supply and use. Due to the large quantity demanded and small unit coil weight, packaging and shipping are generally carried out after the total weight is completed according to the plan. When weighing, the product weight is calculated by reverse calculation, that is, total package weight - auxiliary material weight = actual weight. The final outbound information can vary greatly due to factors such as the dryness of the pallets, the accuracy of material registration and labeling, and the mixing of products of different specifications. In addition, long-term storage without packaging causes surface dust and other conditions, which seriously affect product quality. Under such circumstances, the accuracy of data statistics and the non-ferrous metal yield and other indicators change, which affects the company's production and operation, quality control and improvement, and seriously reduces the company's production efficiency. Therefore, it is necessary to weigh immediately after production to ensure the accuracy of weight data. However, the existing technology lacks a simple and easy-to-operate weighing device suitable for the production process. Utility Model Content

[0020] The device disclosed in this utility model, in use, first controls the system consisting of the top plate and the base plate to rotate to a vertical position along the rotating connection between the vertical suspension arm and the horizontal fixing component. Then, the entire device is adjusted to the height of the copper strip coil (freshly produced copper strip coils are vertically suspended on the cross arm), and the center of the base plate is aligned with the center of the copper strip coil. The entire device is then pushed close to the copper strip coil until the copper strip coil contacts the annular groove on the base plate. A vacuum is then continuously drawn, creating negative pressure in the annular groove, which adsorbs the copper strip coil into the groove. The control device moves to move the copper strip coil to the desired position. Next, the system consisting of the top plate and the base plate is controlled to return to a horizontal state. At this time, the copper strip coil is still adsorbed by vacuum in the annular groove, causing an increase in the weight of the base plate. The weighing sensor transmits the sensed weight increase data signal to the control device, thereby obtaining accurate weight data of the copper strip coil while it is being transported. This device has a simple structure, reasonable design, and is easy to use. It can automatically transport and weigh copper strip coils, greatly reducing production costs and improving production efficiency. Attached Figure Description
