Device for increasing viscosity of winding adhesive tape

According to the technical scheme, the device for increasing the viscosity of the winding rubber strip is characterized by comprising a pressing ring arranged in a circular ring shape; the pricking needles are arranged on the outer side of the pressing ring and arranged around the axis of the pressing ring, and the pricking needles penetrate through one layer of adhesive tape just wound on the forming drum and the upper layer of adhesive tape at the same time; the compression roller shaft is used for driving the pricking needles to be inserted into the two layers of rubber strips; the two layers of rubber strips penetrate through the pricking needles, in the penetrating process, rubber materials on the upper layer of rubber strips at the punctured position can be driven to be mixed into the lower layer of rubber strips through extrusion of the pricking needles, the adhesiveness between the two adjacent layers of rubber strips is improved, and therefore the problem that the two layers of rubber strips are poor
