DETAILED DESCRIPTION
[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0016] See also Figure 1-6 A polyurethane high-pressure foaming machine capable of quickly forming foam comprises a base 1 and a workbench 2. The workbench 2 is located at the upper end of the base 1 and is fixedly connected to the base 1. Three pressure pumps 12 are fixedly installed on the upper surface of the base 1. A control panel 21, a silo 3 and a mixing silo 4 are fixedly connected to the upper end surface of the workbench 2. Two silos 3 are provided. A feed inlet 31 is provided on the upper surface of the silo 3. A mounting frame 32 is fixedly connected to the upper surface of the silo 3. A motor 321 is installed on the upper surface of the mounting frame 32. The motor 3 The output end of the 21 is fixedly connected with a rotating shaft 322, and the outer surface of the lower end of the rotating shaft 322 is fixedly connected with a driving gear 323. The upper surface of the mounting frame 32 is fixedly installed with a hot oil bin 33, and the upper surface of the hot oil bin 33 is provided with an oil inlet 331. The lower end of the hot oil bin 33 is connected with an oil delivery pipe 332, and the lower end of the oil delivery pipe 332 is rotatably connected with a rotating rod 34. The rotating rod 34 is set as a hollow structure. The rotating rod 34 is located inside the silo 3, and the upper end of the rotating rod 34 passes through the silo 3. The outer surface of the rotating rod 34 is fixedly connected with a secondary driving gear 341, the secondary gear 341 is meshed with the driving gear 323, and a plurality of stirring rods 342 are installed on the outer surface of the rotating rod 34. The interior of the stirring rod 342 is set as a hollow structure. When in use, the foaming raw materials are respectively put into the two silos 3 from the feeding port 31, and then the motor 321 is started. The motor 321 drives the rotating shaft 322 to rotate, and then drives the driving gear 323 to rotate. The driving gear 323 then drives the secondary gear 341 to rotate through meshing, and then drives the stirring rod 342 to rotate, stirring The rod 342 stirs the raw materials inside the silo 3 and performs foaming by applying pressure. At the same time, during the stirring process, in order to accelerate the foaming speed, hot oil can be injected into the oil inlet 331. The hot oil can flow to the inside of the rotating rod 34 through the hot oil silo 33 and the oil pipe 332, and then be transported to the stirring rod 342 by centrifugal force, so that the heat of the hot oil is evenly distributed inside the silo 3. The hot oil can heat up the inside of the silo 3 to ensure the foaming temperature, thereby achieving the effect of accelerating foaming and improving the subsequent work efficiency.
[0017] Furthermore, a support leg 11 is fixedly connected to the lower end surface of the base 1, and a pressure-increasing pipe 121 is connected to the pressure delivery end of the pressure pump 12. The pressure-increasing pipe 121 is respectively inserted into the interior of the silo 3 and the mixing silo 4. When in use, the pressure pump 12 is used to pressurize the interior of the silo 3 and the mixing silo 4 to complete the foaming work.
[0018] Furthermore, the hot oil tank 33 is designed as a hollow structure with hot oil inside. A bearing 333 is provided at the connection between the oil pipe 332 and the rotating rod 34. The hot oil tank 33 is communicated with the interior of the rotating rod 34 through the hot oil tank 33. When in use, the rotating rod 34 has the bearing 333 at the connection between the oil pipe 332 and the rotating rod 34, so when it is rotated, it will not affect the oil pipe 332 from transporting hot oil to the interior of the rotating rod 34.
[0019] Furthermore, the interior of the rotating rod 34 is connected to the interior of the stirring rod 342. A rubber head 343 is fixedly connected to the front end of the stirring rod 342. The rubber head 343 contacts the inner wall of the silo 3. When in use, when the stirring rod 342 rotates, the rubber head 343 at its front end will continuously rub against the inner wall of the silo 3, thereby generating heat by friction, which can further increase the internal temperature of the silo 3, thereby accelerating the foaming speed.
[0020] Furthermore, a first temperature sensor 35 is installed on the outer surface of the silo 3, a second temperature sensor 41 is installed on the outer surface of the mixing silo 4, a feed pipe 42 and a discharge pipe 43 are provided on the outer surface of the mixing silo 4, and the interior of the mixing silo 4 is communicated with the interior of the silo 3 through the feed pipe 42. When in use, the first temperature sensor 35 and the second temperature sensor 41 are used to monitor the temperature inside the silo 3 and the mixing silo 4 in real time, and the feed pipe 42 can suck the materials inside the two silos 3 into the mixing silo 4 for mixing and stirring.
[0021] In summary, the polyurethane high-pressure foaming machine that can quickly form foams proposed by the present invention, first, when the foaming work starts, the foaming raw materials are put into the silo 3 through the feed port 31 of the silo 3. Then, the motor 321 is started, and the motor 321 drives the driving gear 323 to rotate through the rotating shaft 322, and the driving gear 323 is meshed with the secondary driving gear 341, thereby driving the rotating rod 34 located inside the silo 3 to rotate, and the stirring rod 342 is installed on the outer surface of the rotating rod 34. As the rotating rod 34 rotates, the stirring rod 342 also rotates inside the silo 3, and the raw materials inside the silo 3 are fully stirred. During the stirring process, the hot oil in the hot oil silo 33 is transported to the inside of the rotating rod 34 through the oil pipe 332, and then transported to the stirring rod 342 by centrifugal force. The heat of the hot oil increases the temperature inside the silo 3, ensuring the temperature requirement during the foaming process, thereby accelerating the foaming speed. At the same time, in order to further accelerate the foaming speed, a rubber head 343 is fixedly connected to the front end of the rotating rod 34, and the rubber head 343 contacts the inner wall of the silo 3. When the stirring rod 342 rotates, the friction between the rubber head 343 and the inner wall of the silo 3 generates heat, further increasing the temperature inside the silo 3, thereby accelerating the foaming speed. In addition, a first temperature sensor 35 is installed on the outer surface of the silo 3, and a second temperature sensor 41 is installed on the outer surface of the mixing silo 4, which is used to monitor the temperature inside the silo 3 and the mixing silo 4 in real time. When the temperature reaches the set foaming temperature, the feed pipe 42 inside the mixing silo 4 sucks the materials in the two silos 3 into the mixing silo 4 for mixing and stirring. Through the above working principle, the polyurethane high-pressure foaming machine can achieve rapid foam formation and improve subsequent work efficiency.
[0022] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
