Description

Technical Field

[0001] The utility model relates to the technical field of tire tread rubber material processing, in particular to a material head heating device for tire tread rubber material processing. Background Art

[0002] Tire tread rubber refers to a layer of rubber with patterns printed on the surface of the tire, which is the outermost layer of the tire in contact with the road surface. It can give the tire traction, cushion the impact and swing during driving, and prevent the cord layer from being cut and punctured. It plays a vital role in the driving of the tire. Before the tire tread is attached to the belt drum, the tread head needs to be heated to increase the adhesion of the head and tail heads. In order to prevent the loose connection at the rubber strip joint from affecting the quality of the tire blank and causing tire defects, some technologies have proposed relevant technical structures to assist in the processing of tread rubber. For example, there is a utility model patent with a publication number of CN212528789U, which proposes a tire tread rubber end surface heating device, which adopts two sets of heaters to heat the front and rear end surfaces of the tread rubber at the same time, and the bonding effect after the double end surfaces are heated is good; the heater adopts a side insertion installation method, which is convenient for operators to maintain and save time and cost; the bottom heating method is adopted, which does not occupy the space above the conveyor, and is easier to modify for multi-layer conveyors.

[0003] From the above disclosed technical contents, theoretically speaking, the implementation of the relevant technical structure is beneficial to the processing of tread rubber. However, according to the description in the above disclosed technical contents, in order to reduce the installation area of ​​the heating device, the heating device is installed at the bottom of the tread rubber. At this time, when the tread rubber is conveyed on the roller conveyor, impurities adhered to the bottom of the tread rubber are easy to fall into the interior of the heating device. As the temperature of the electric heating rod continues to increase after the power is supplied, the direct contact between the impurities and the electric heating rod causes a safety hazard in the process of heating the tread rubber.
