Die heating device of tyre rubber extruding machine

Abstract

The invention discloses a tire profile rubber extruder die heating device. The heating device comprises a box body and a temperature controller. One end of the box body is provided with an openable box door. An insulated heat preservation layer is clamped between an inner surface board and an outer surface board of the box board. An electrical heating wire or film is arranged between the inner surface board and the insulated heat preservation layer. The electrical heating wire or film is connected with a relay. The temperature controller comprises a temperature control apparatus and a relay which are arranged in an operation box and 2 to 5 temperature sensors which are arranged in the box and connected with a signal end of the temperature control apparatus. The operation box has a power switch and a heating indication lamp. A die is placed in the box, a temperature is set on the temperature control apparatus, the electrical heating wire or film is powered to carry out electric heating and the heating indication lamp turns on. When the temperature rises to a preset value, the temperature control apparatus sends a signal to the relay and the electrical heating wire or film stops heating. The die heating device also has a fan with a wind outlet inserted into the box body to promote air circulation and achieve a consistent temperature in the box body. The die heating device has good pre-heating effect, is particularly applicable to giant tire production for heating, can automatically control temperature, and is convenient in operation, simple in structure and low in cost.

Description

(1) Technical field [0001] The invention relates to the technical field of tire processing machinery, in particular to a die heating device for a tire rubber extruder. (2) Background technology [0002] In the tire manufacturing process, the extruder needs to produce various types of rubber such as tire tread rubber, sidewall rubber, shoulder pad rubber, nipple, large ring rubber and apex rubber. . The main key to ensure the quality of extruded rubber is the mouth shape. The first is that the design of the mold mouth should meet the requirements. In addition, in the production process of the extruder, in addition to the combination of the rubber material, the uniformity of the glue supply, and the control of the temperature difference in each section of the machine body, the preheating temperature of the mold is also guaranteed. important factor in quality. The general extruder die is only preheated by the extruder itself. The volume of the rubber used in the production ...

AI Technical Summary

Problems solved by technology

The size of the rubber used in the production of giant tires has doubled, and the die plate has also become thicker and larger. It is impossible to preheat the die evenly and reach the ideal temperature on the extruder.

But currently there is no device for lip warming
