[0025] A raw material heating device for automobile brake pipe production comprises a mixing drum 1, wherein a mixing chamber 2 is provided inside the mixing drum 1, a motor 3 is fixedly installed at the middle of the top of the mixing drum 1, and a mixing mechanism 4 is arranged at one end of the output shaft of the motor 3 located inside the mixing chamber 2, and the mixing mechanism 4 comprises a transmission shaft 401, an agitator 402 and a scraper 403; a heating mechanism 5 is arranged at the outer side of the middle of the mixing drum 1, and the heating mechanism 5 comprises a heating drum 501, a heating tank 502 and a heating tube 503, a feeding port 6 is arranged at one side of the bottom end of the mixing drum 1 located at the mixing chamber 2, and a feeding port 15 is connected to the top of one side of the mixing drum 1, a transmission shaft 401 is fixedly installed at one end of the output shaft of the motor 3 located inside the mixing chamber 2, a plurality of agitators 402 are arranged in sequence on the four sides of the outer side of the transmission shaft 401 from top to bottom, a scraper 403 is fixedly connected to one side of the bottom end of the transmission shaft 401, and an arc-shaped scraper head 14 is arranged at one end of the agitator 402 away from the transmission shaft 401;

[0026] In this embodiment, during stirring, the motor 3 is started. After the motor 3 is started, the multiple agitators 402 are driven by the transmission shaft 401 to stir the softened rubber raw materials inside the stirring chamber 2. When the transmission shaft 401 rotates, the scraper 403 at the bottom is driven to stir synchronously, and an arc-shaped scraper head 14 is provided at the outer end of the agitator 402. In this way, the agitator 402 and the scraper 403 can scrape the inner wall of the stirring chamber 2 at the same time, which can prevent the rubber raw materials from sticking to the inner wall of the stirring chamber 2, resulting in uneven mixing, thereby improving the mixing efficiency.

[0027] like Figure 2As shown, the outer side of the middle of the mixing drum 1 is fixedly connected to the heating drum 501, the inner side of the heating drum 501 is provided with a heating groove 502, the inner side of the heating groove 502 is provided with a heating tube 503 in an annular shape, the two ends of the heating tube 503 are located at the top of the heating drum 501, and both sides are provided with power connection terminals 7, the inner side surface of the mixing drum 1 located at the heating drum 501 is provided with a ceramic inner shell 8, the outer side surface of the ceramic inner shell 8 is provided with a ceramic tube rack 9 in an annular shape, and the heating tube 503 is sleeved with the ceramic tube rack 9;

The heating tube 503 is supported by the ceramic tube rack 9. When the heating tube 503 is heated, the heat is transferred to the ceramic inner shell 8 through the ceramic tube rack 9 and the oil, and then the heat is transferred to the mixing cylinder 1 through the ceramic inner shell 8, and finally the rubber raw material inside the mixing chamber 2 is heated.
