Technical Field

[0001] This utility model relates to the field of feeding mechanism technology, specifically a stable feeding mechanism for a polyurethane foaming machine. Background Technology

[0002] Polyurethane foaming machines are specialized production equipment for polyurethane foam tires.

Polyurethane foam tires are made by foaming polyether polyols and polyisocyanates in the presence of various chemical additives such as foaming agents, catalysts, and emulsifiers through chemical reaction. In the process of using polyurethane foaming machines, a special feeding mechanism is usually used to transport materials. However, some problems still occur in the actual use of existing feeding mechanisms. For example, application number CN202021673601.6 discloses an automatic feeding device for a polyurethane foaming machine, including a mounting base plate.

A conveying pipe is fixedly connected to the output end of the conveying pump. The end of the conveying pipe away from the conveying pump is fixedly connected to the upper surface of the foaming tank. This device facilitates control of the conveying amount. Most existing feeding mechanisms have simple structures and often lack effective means to control the material output. When the material temperature is not up to standard, it may lead to poor subsequent foaming effect and affect the use effect.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0023] Combination Figures 1-3 A stable feeding mechanism for a polyurethane foaming machine includes a mounting platform 1 and a heated storage tank 11 fixedly connected to the top of the mounting platform 1. The heated storage tank 11 is provided in two sets. A mounting frame 12 is also fixedly connected to the top of the mounting platform 1. A temporary storage box 121 is fixedly connected to the mounting frame 12. A feed inlet 122 is fixedly connected to the top of the temporary storage box 121. A fixing box 13 is fixedly connected to the bottom of the mounting platform 1. A motor 131 is fixedly connected inside the fixing box 13. The heated storage tank 11 is provided with a control structure for controlling the material. The control structure includes a placement box 14 fixedly connected to one side of the heated storage tank 11.

[0024] The present invention will be further described below with reference to the embodiments. Example 1

[0025] To address the problem that most existing feeding mechanisms have a simple structure and often lack effective means to control material output, which can lead to poor subsequent foaming effects and affect the overall performance when the material temperature is not up to standard, this embodiment discloses the following technical solution, specifically as follows: Figures 1-4As shown, a control pump 111 is fixedly connected to the top of the heating storage tank 11. The control pump 111 is fixedly connected to the temporary storage box 121. A bevel gear 132 is fixedly connected to the output end of the motor 131. Two sets of bevel gears 132 are provided. A bevel gear 133 is meshed with one side of the bevel gear 132. A stirring rod 134 is fixedly connected to the top of the bevel gear 133. The stirring rod 134 is rotatably connected inside the heating storage tank 11. A discharge pipe 141 is fixedly connected to one side of the placement box 14. A temperature sensor 1411 is fixedly connected to the discharge pipe 141. The top of the placement box 14... A telescopic cylinder 142 is fixedly connected to the storage box 121. A sliding plate 143 is fixedly connected to the output end of the telescopic cylinder 142. A connecting frame 144 is fixedly connected inside the storage box 14. A through-hole 145 is opened on the connecting frame 144. The sliding plate 143 is slidably connected to the inner side of the connecting frame 144. During use, two different materials can be added into the corresponding feed inlets 122. The materials enter the storage box 121 through the feed inlets 122. When feeding is required, the control pump 111 can be started. The control pump 111 opens and then feeds the materials inside the storage box 121. The material is conveyed into the heated storage tank 11, and the heated storage tank 11 and motor 131 are started. The heated storage tank 11 can increase its internal temperature. The start of motor 131 causes the two sets of bevel gears 132 to rotate. The bevel gears 132 drive the bevel gears 133 to rotate, which in turn drive the two sets of stirring rods 134 to rotate. The stirring rods 134 rotate inside the heated storage tank 11, which can stir the raw materials inside the heated storage tank 11. Then, the telescopic cylinder 142 can be activated. The telescopic cylinder 142 drives the sliding plate 143 to move, which in turn causes the connecting frame 144 to open. When the material is opened, it can enter the discharge pipe 141 through the port 145 on the connecting frame 144. When the temperature sensor 1411 detects that the temperature inside the discharge pipe 141 has not reached the normal value, the temperature sensor 1411 drives the telescopic cylinder 142 to start, which in turn causes the sliding plate 143 to move. The sliding plate 143 slides inside the connecting frame 144, thereby closing the port 145 and preventing other materials inside the heated storage tank 11 from entering the discharge pipe 141. This realizes the function of controlling the conveyed material according to the actual situation and improves the use effect. Example 2

[0026] To address the issue that existing feeding mechanisms generally require an additional mixing structure to agitate the two materials during output to ensure the polyurethane foaming machine functions properly, but this results in high energy consumption and reduced subsequent work efficiency, this embodiment discloses the following technical solution, specifically as follows: Figure 1 and Figure 5As shown, a fixed box 15 is fixedly connected to one side of the mounting platform 1, and a discharge pipe 151 is fixedly connected to one side of the fixed box 15. Two sets of discharge pipes 141 are fixedly connected to discharge pipes 151. A motor 152 is fixedly connected inside the fixed box 15. A propeller blade 153 is fixedly connected to the output end of the motor 152. The propeller blade 153 is rotatably connected inside the discharge pipe 151. When the material enters the discharge pipe 141, it will enter the discharge pipe 151 through the discharge pipe 141. Both the discharge pipe 141 and the discharge pipe 151 are made of heat-insulating material, so the material will not cool down during the conveying process. During the conveying process, the motor 152 can be started, and the motor 152 drives the propeller blade 153 to rotate inside the discharge pipe 151. This allows for the simultaneous conveying of materials and stirring of two different materials, thus achieving the function of stirring materials during the conveying process and improving work efficiency.
