Background The tyre is used as the core component for the contact between the vehicle and the ground, the performance of the tyre directly affects the running safety, comfort and durability, the traditional tyre crown and the tyre side mostly adopt a formula system of rubber matrix mixed with reinforcing fillers such as carbon black, white carbon black and the like, and during the running process of the vehicle, the tyre crown and the ground generate a large amount of heat due to friction, and the tyre side generates heat due to internal consumption during the deformation process. The chinese patent publication No. CN114603817a discloses an extruder for tire rubber, which comprises a supporting frame and a machine part arranged on the supporting frame, wherein a rubber extrusion box is arranged on the machine part, an input pipe is arranged at the material inlet end of the rubber extrusion box, a pipe bearing part for bearing the input pipe is arranged on the machine part, and the input pipe is limited at the material inlet end of the rubber extrusion box in a swinging manner. In the prior art, as the rubber material has the principle of thermal expansion and cold contraction, and the temperature value of the rubber material after being discharged along the extrusion port is higher than the room temperature and needs to be cooled and contracted, if the temperature of the extruded rubber material in the gear pump changes, the cold contraction amount generated after the extruded rubber material is cooled to the room temperature is also different, and the section size of the extruded rubber material is further caused to be unsatisfactory. In the actual use process of the adjusting device, the area of the extrusion opening is changed due to temperature change, and the amount of sizing materials discharged from the extrusion opening is adjusted, but if the area of the extrusion opening is increased, gaps are enlarged, air is mixed into the extrusion sizing materials, the products are disqualified, and if the area of the extrusion opening is reduced, gaps are reduced, and the sizing materials at the extrusion opening of the gear pump position are accumulated, so that the self structure of the gear pump is influenced. In the process of heating and conveying the sizing material by the extruder, the inside of the extruder and the inside of the gear pump still can be blocked, but the generation of the blocking condition and the determination of the blocking position can not be accurately judged only by single temperature detection of the existing device, and the normal continuous discharge of the subsequent sizing material is finally influenced.
