Abstract

The utility model relates to the technical field of mulching film production equipment, in particular to a biodegradable cooling device for agricultural mulching film processing, which comprises a U-shaped seat, a cooling mechanism is arranged in the U-shaped seat, and the cooling mechanism comprises a first roller, a second roller and a third roller which are sequentially arranged along the conveying direction of a mulching film body. The two ends of the first roller, the two ends of the second roller and the two ends of the third roller communicate with sleeves rotationally connected with the U-shaped bases correspondingly, spiral pipes are fixedly connected to the inner walls of the first roller, the second roller and the third roller correspondingly, and one end of each spiral pipe extends out of the corresponding sleeve on one side and is rotationally connected with a water inlet pipe through a rotating connector. By means of the three-stage gradient cooling roller, the optimized layout of the spiral pipe and the intelligent temperature control system, precise temperature control and efficient cooling of the degradable mulching film are achieved, and the product quality and the production efficiency are remarkably improved.
