Description

TECHNICAL FIELD

[0001] The application relates to the technical field of coil transportation, in particular to a spray cooling device for coil wire transportation. BACKGROUND

[0002] In the production process of coil wire, the wire needs to be transported in a flat state after the rolling process. To meet the subsequent storage, transportation and processing requirements, the flat wire needs to be regularized into uniform vertical coils, which is the task of the coil collecting station. The operation efficiency and stability of the coil collecting station are directly related to the overall production rhythm and yield of the production line. The coil collecting station is located at the tail end of the coil cooling line of the high-speed wire production line. After the flat wire enters the coil collecting station through the conveying device, the winding pipe in the station starts to rotate, and the wire is stacked layer by layer from the lower side to the upper side of the winding core, and gradually wound into a vertical coil. After winding, the lifting device lifts the winding core and the coil together, and then the coil is unloaded from the winding core by the coil transport trolley.

[0003] Before the coil wire is sent into the coil collecting station, it must undergo heat dissipation process to ensure that the temperature of the wire is reduced to a certain standard range. However, the current air cooling method is not satisfactory in terms of cooling effect, and it is difficult to meet the cooling requirements of the wire. How to enhance and improve the cooling means of the coil wire during transportation has become a technical problem to be solved by the technical personnel in the field. CONTENT OF THE UTILITY MODEL
