Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of large-diameter coil production, and in particular to a large-diameter coil production line feeding device. BACKGROUND

[0002] Copper pipes are commonly used for refrigeration or heating pipelines, and are most widely used in the field of white household appliances. For example, in the condenser of an air conditioner, a copper pipe is one of the best connecting pipelines. Due to the relatively long length and good ductility of the copper pipe, in order to save space, the finished copper pipe is generally wound into a spiral coil structure for storage and transportation. When feeding towards a large-diameter coil production line, a crane or a special structure of a crane is generally used to lift the coil out for feeding operation.

[0003] For example, a Chinese utility model patent with the publication number CN210048254U discloses a copper pipe large-diameter coil unloading device, which includes a base and a transportation platform. A plurality of cylinders are fixedly installed on the upper surface of the base, and the piston rods of the cylinders are connected with a lifting disc for placing a tray. An L-shaped limiting block is fixedly connected to the upper surface of the lifting disc. The transportation platform is located above the base and has a first through hole matched with the lifting disc. A fixed plate is fixedly installed on the upper surface of the transportation platform, and a folding plate is rotatably connected to the side of the fixed plate close to the first through hole.

[0004] According to the related technology described above, the inventors believe that the copper pipe large-diameter coil unloading device sets the lifting disc and the fixed plate rotatably connected with the folding plate, so that the hydraulic forklift can directly drag the coil away from the lifting disc, and the placement position of the coil on the lifting disc is standardized. However, the copper pipe large-diameter coil unloading device does not have a protection structure, so that the exposed copper pipe is easily bumped and worn by external factors. SUMMARY

[0005] In order to improve the problem that the exposed copper pipe is easily bumped and worn by external factors, the present application provides a large-diameter coil production line feeding device.

[0006] The large-diameter coil production line feeding device provided by the present application adopts the following technical solution:
