[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4A novel polyurethane foaming device includes a cylinder 1, which is characterized in that: a stirring mechanism is installed in the cylinder 1. By providing the stirring mechanism, it is convenient to fully stir the raw materials, thereby improving the polyurethane foaming efficiency. A heating mechanism is installed in the cylinder 1. By providing the heating mechanism and cooperating with the stirring mechanism, it is convenient to fully heat the raw materials, which is beneficial to the foaming of polyurethane. The stirring mechanism includes a motor 21, which is fixedly installed at the top of the cylinder 1. The motor 21 drives the mounting plate 210 to perform circular motion. The rotating shaft of the motor 21 rotates and passes through the inner wall of the cylinder 1. The rotating shaft end of the motor 21 is fixedly installed with a mounting plate 210. The mounting plate 210 is in the shape of a square plate. By providing the mounting plate 210, it is convenient to undertake the installation of the first rotating rod 28 and the spiral rod 22.

[0022] In detail, the bottom end of the mounting plate 210 is rotatably connected with a first rotating rod 28 through a bearing. There are two first rotating rods 28, and the two first rotating rods 28 are symmetrically arranged with the motor 21 as the center. The first rotating rod 28 is in the shape of a cylindrical rod. The first rotating rod 28 is arranged to facilitate the installation of the gear 29. A gear 29 is fixedly installed at the bottom end of the first rotating rod 28. There are two gears 29, and both gears 29 are meshed with the gear ring 211. The two gears 29 are symmetrically arranged with the motor 21 as the center. A second rotating rod 25 is fixedly installed at the bottom end of the gear 29. There are two second rotating rods 25, and stirring rods 26 are fixedly installed on the two second rotating rods 25. The stirring rods 26 are in the shape of a square rod. The stirring rod 26 is convenient for stirring the raw materials, which is beneficial for mixing and heating the raw materials. A connecting rod 27 is fixedly installed on the inner wall of the cylinder 1. There are two connecting rods 27, and the two connecting rods 27 are symmetrically arranged with the motor 21 as the center. A gear ring 211 is fixedly installed on one end of the connecting rod 27, and the gear ring 211 is meshed with the gear 29. When the mounting plate 210 rotates, the mounting plate 210 will drive the gear 29 to perform a circular motion through the first rotating rod 28. Since the gear 29 is meshed with the gear ring 211, the gear 29 will rotate while performing a circular motion. During the movement of the gear 29, the stirring rod 26 will be driven by the second rotating rod 25 to rotate while performing a circular motion, thereby achieving the purpose of fully stirring the raw materials.

[0023] Furthermore, a receiving rod 23 is fixedly installed on the inner wall of the cylinder 1. There are two receiving rods 23, and the two receiving rods 23 are symmetrically arranged with the motor 21 as the center. The receiving rod 23 is arranged to facilitate the installation of the circular tube 24. The circular tube 24 is fixedly installed on one end of the receiving rod 23, and a spiral rod 22 is fixedly installed on the bottom end of the mounting plate 210. The spiral rod 22 rotates in the circular tube 24. When the mounting plate 210 rotates, the mounting plate 210 will drive the spiral rod 22 to rotate, and the spiral rod 22 will drive the lower layer of raw materials to enter the upper layer along the circular tube 24, which is beneficial to the mixing and stirring of the raw materials.

[0024] Furthermore, the heating mechanism includes mounting rods 32, and the number of the mounting rods 32 is twenty-four. The twenty-four mounting rods 32 are respectively fixedly mounted on the inner wall of the circular tube 24 and the cylinder 1. The mounting rods 32 are provided to facilitate the installation of the heating rod 31. The heating rod 31 is fixedly mounted on one end of the mounting rod 32. When heating is required, the heating rod 31 is started, and driven by the stirring mechanism, the heating rod 31 will fully heat the raw materials.

[0025] Working mode: When working, the polyurethane foaming raw material is added into the cylinder 1, and then the motor 21 is started. The motor 21 drives the mounting plate 210 to rotate. When the mounting plate 210 rotates, the mounting plate 210 will drive the gear 29 to perform a circular motion through the first rotating rod 28. Since the gear 29 is meshed with the gear ring 211, the gear 29 will rotate while performing a circular motion. During the movement, the gear 29 will drive the stirring rod 26 to rotate while performing a circular motion through the second rotating rod 25. The stirring rod 26 will stir the raw materials. At the same time, when the mounting plate 210 rotates, the mounting plate 210 will drive the spiral rod 22 to rotate, and the spiral rod 22 will drive the lower layer of raw materials along the circular tube 24 into the upper layer, which is beneficial to the mixing and stirring of the raw materials, thereby achieving the purpose of fully stirring the raw materials, which is beneficial to the foaming of polyurethane. When heating is required, the heating rod 31 is started. Driven by the stirring mechanism, the heating rod 31 will fully heat the raw materials in motion, which is beneficial to the foaming of polyurethane.
