[0028] Reference Figure 2 and Figure 3 A wall scraping structure 8 is provided on the rotating shaft 6. The wall scraping structure 8 is mainly composed of two fixed rods 81. The two fixed rods 81 are respectively fixedly connected to the rotating shaft 6. An L-shaped rod 83 is provided on the fixed rod 81. The raw material is introduced into the reactor 1 through the feed pipe 4, and the first motor 3 is started. The output shaft of the first motor 3 drives the rotating shaft 6 to rotate, and then drives the stirring blade 7 to rotate to stir the raw material. When the rotating shaft 6 rotates, it will drive the two fixed rods 81 to rotate, and then drive the two L-shaped rods 83 to rotate. The L-shaped rods 83 scrape the inner bottom wall of the reactor 1. , thereby avoiding the situation that the polyester resin is easily adhered to the inner wall of the reactor 1 due to its high viscosity, and the polyester resin adhered to the barrel wall is difficult to discharge when unloading, resulting in a waste of raw materials. The fixed rod 81 is provided with an adjustment groove 82, and an L-shaped rod 83 is slidably connected in the adjustment groove 82. When the L-shaped rod 83 is worn during use, the L-shaped rod 83 is slid so that the L-shaped rod 83 fits the inner wall. The L-shaped rod 83 is fixedly connected to the first spring 84, and one end of the first spring 84 is fixedly connected to the inner wall of the adjustment groove 82. When the L-shaped rod 83 is against the inner wall When scraping off the attachments on the reactor 1, the first spring 84 is in a contracted state, so the rebound elastic force of the first spring 84 acts on the L-shaped rod 83, thereby enhancing the scraping effect. A slide groove 85 is provided on the rotating shaft 6, and a scraper 86 is slidably connected in the slide groove 85. The rotation of the rotating shaft 6 will drive the scraper 86 to rotate, and then the inner bottom wall of the reactor 1 is scraped off to prevent the material from adhering to the inner bottom wall of the reactor 1. A second spring 87 is fixedly connected to the inner wall of the slide groove 85, and one end of the second spring 87 is fixedly connected to the scraper 86. When the scraper 86 hits the bottom wall When scraping, the second spring 87 is in a contracted state, so the rebound force of the second spring 87 acts on the scraper 86, thereby enhancing the scraping effect on the inner bottom wall. The scraper 86 is slidably connected to two sliders 88, and the slider 88 is fixedly connected to a telescopic rod 89. One end of the telescopic rod 89 is fixedly connected to the L-shaped rod 83.

Rotating shafts 92 are rotatably inserted on both sides of the rectangular frame 91, and three stirring rods 93 are fixedly connected to the rotating shaft 92. During the stirring process of the stirring blade 7 stirring the raw materials, two rotating shafts 92 can be rotated, so that several stirring rods 93 vertically stir the raw materials, thereby enhancing the stirring effect to improve the reaction effect. A second bevel gear 96 is fixedly connected to one end of the rotating shaft 92, and a second motor 94 is fixedly connected to the rectangular frame 91. A first bevel gear 95 is fixedly connected to the output shaft of the second motor 94, and the first bevel gear 95 is meshed with the two second bevel gears 96. When the second motor 94 is started, the output shaft of the second motor 94 drives the first bevel gear 95 to rotate, and the rotation of the first bevel gear 95 drives the two second bevel gears 96 to rotate in opposite directions, thereby driving the two rotating shafts 92 to rotate, making the stirring operation more convenient.

[0030] Working principle: the raw material is introduced into the reactor 1 through the feed pipe 4, and the first motor 3 is started. The output shaft of the first motor 3 drives the rotating shaft 6 to rotate, and then drives the stirring blade 7 to rotate to stir the raw material. When the rotating shaft 6 rotates, it will drive the two fixed rods 81 to rotate, and then drive the two L-shaped rods 83 to rotate. The L-shaped rods 83 scrape the inner bottom wall of the reactor 1, thereby avoiding the situation that the polyester resin is easy to adhere to the inner wall of the reactor 1 due to its high viscosity. When the polyester resin adhered to the barrel wall is difficult to discharge during material discharge, resulting in waste of raw materials. When the L-shaped rod 83 is worn during use, the L-shaped rod 83 is slid so that the L-shaped rod 83 fits with the inner wall. When the L-shaped rod 83 scrapes the attachments on the inner wall, the first spring 84 is in a contracted state, so the rebound elastic force of the first spring 84 acts on the L-shaped rod 83, thereby enhancing the scraping effect. The rotation of the rotating shaft 6 will drive the scraper 86 to rotate, and then the inner bottom wall of the reactor 1 is scraped. The scraper 86 is connected to the L-shaped rod 83 to make the rotation of the L-shaped rod 83 more stable. The slider 88 cooperates with the telescopic rod 89 to prevent the L-shaped rod 83 from sliding in the adjustment groove 82 and the scraper 86 from sliding in the slide groove 85. The stirring blade 7 can rotate the two rotating shafts 92 during the stirring of the raw materials, so that the several stirring rods 93 stir the raw materials vertically, thereby strengthening the stirring effect and improving the reaction effect. The second motor 94 is started, and the output shaft of the second motor 94 drives the first bevel gear 95 to rotate. The rotation of the first bevel gear 95 drives the two second bevel gears 96 to rotate in opposite directions, thereby driving the two rotating shafts 92 to rotate, making the stirring operation more convenient.
