[0002] Unsaturated polyester resin is generally a linear high-molecular compound with ester bonds and unsaturated double bonds formed by the polycondensation of unsaturated dibasic acids and diols or saturated dibasic acids and unsaturated diols. Until the expected acid value (or viscosity) is reached, after the polyesterification polycondensation reaction ends, a certain amount of vinyl monomer is added while it is hot to form a viscous liquid. Such a polymer solution is called unsaturated polyester resin. Unsaturated polyester resin has relatively high tensile, bending, and compressive strengths due to its good mechanical properties.

[0024] When transporting solid raw materials, the electric telescopic rod 9 extends to drive the scraper 15 to move outside the feeding hopper 3. By rotating the connecting plate 10, the first connecting rod 12 and the second connecting rod 13 are driven to exchange working positions. After the electric telescopic rod 9 contracts, the screw rod 20 can be driven to extend into the inside of the feeding hopper 3. Then, when transporting solid raw materials, the screw rod 20 is driven to rotate by the first connecting rod 12 to feed the solid materials, avoiding the occurrence of material blockage, improving the smoothness of feeding, and improving the production and processing efficiency of unsaturated polyester resin.

[0025] A plurality of connecting bolts 2 are arranged on the upper surface of the mounting plate 1, and the bottom ends of the connecting bolts 2 extend below the mounting plate 1.

[0026] The multiple connecting bolts 2 facilitate the installation of the mounting plate 1 on the top of the reaction kettle, and are also convenient for later disassembly, maintenance, or cleaning operations of the device, reducing the maintenance cost of the device.

[0027] A receiving box 4 is fixedly connected to the upper surface of the mounting plate 1. A connecting shaft 7 is vertically and rotatably arranged in the receiving box 4.

[0033] During operation, when transporting liquid raw materials, the rotation of the second connecting rod 13 drives the cross bar 14 to rotate, thereby driving the scraper 15 to scrape the inner wall surface of the feeding hopper 3, avoiding the situation that liquid raw materials adhere to the inner wall surface of the connecting bolt 2, improving the thoroughness of liquid raw material feeding. When transporting solid raw materials, the electric telescopic rod 9 extends to drive the scraper 15 to move outside the feeding hopper 3. By rotating the connecting plate 10, the first connecting rod 12 and the second connecting rod 13 exchange working positions. After the electric telescopic rod 9 contracts, the screw rod 20 can be driven to extend into the interior of the feeding hopper 3.
