[0033] Please refer to Figures 1 - 3 , a feeding device 200 for feeding EPS raw materials into the inner cavity of the conveying device 100 is installed at the upper right end of the conveying device 100. A scraping device 300 for scraping EPS raw materials is installed at the connection between the feeding device 200 and the inner cavity of the conveying device. A gear 220 for controlling the rotation of the scraping device 300 is installed at the lower end of the feeding device 200. A first bevel gear 222 is connected to the middle of one end face of the gear 220. A second bevel gear 230 meshing with the first bevel gear 222 is movably installed at the lower end of the feeding device 200 where the gear 220 is located. The motor 120 synchronously controls the second bevel gear 230 to drive the first bevel gear 222 to rotate. A second pulley 231 corresponding to the first pulley 122 is provided at the end of the second bevel gear 230. The first pulley 122 and the second pulley 231 are sleeved and connected by a belt body 130.

[0034] In this embodiment, the belt body 130 is sleeved in the middle of the first pulley 122, and the belt body 130 is used to cooperate with the first pulley 122 to control the rotation of the second bevel gear 230. When the motor 120 is started, it drives the output shaft 121 to rotate. While driving the conveying auger 110 to convey EPS raw materials, the first pulley 122 cooperates with the belt body 130 to drive the second bevel gear 230 to rotate. The second bevel gear 230 meshes with the first bevel gear 222, so that the gear 220 synchronously drives the scraping device 300 to rotate, scraping the EPS raw materials on the inner wall of the feeding device 200, facilitating the EPS raw materials to fall into the inside of the conveying device 100.
