[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0026] Example 1: AsFigures 1-3 The technical solution shown is a polyurethane foaming machine for preventing internal wall adhesion. In order to solve the problem of inconvenient material mixing during polyurethane foaming, the following are disclosed: a base 1 and a foaming chamber 2 set at the upper end of the base 1. A feeding port 3 is set on the upper left side of the foaming chamber 2, and an additive addition port 4 is set on the upper right side of the foaming chamber 2. A discharge valve port 5 is connected to the lower end of the foaming chamber 2, and the lower end of the discharge valve port 5 passes through the center of the base 1. A drive motor 6 is fixedly installed at the upper end of the foaming chamber 2, and a rotating rod 7 is fixedly installed at the output end of the drive motor 6. The rotating rod 7 is rotatably connected to the foaming chamber 2, and a stirring rod 8 is fixedly installed on the surface of the rotating rod 7.

[0027] When using this polyurethane foaming machine, after adding polyurethane material into the foaming chamber 2 on the base 1 through the feeding port 3, the drive motor 6 is started. The start of the drive motor 6 drives the rotating rod 7 to rotate. When the rotating rod 7 rotates, the polyurethane material inside the foaming chamber 2 is stirred by the stirring rod 8. At the same time, chemical agents for polyurethane foaming are added through the additive addition port 4. After the polyurethane material foaming is completed, the material is discharged through the opening of the discharge valve port 5. This can help the mixing of polyurethane foaming materials, improve the convenience of polyurethane foaming, and make it easy to use.

[0028] Example 2: Figures 1-4 The technical solution shown, based on Embodiment 1, in order to solve the problem that polyurethane material easily sticks to the inner wall when discharged after foaming, discloses: a cleaning scraper 10 is attached to the inner wall of the base 1, and an anti-adhesion mechanism is provided on the inner side of the cleaning scraper 10. The anti-adhesion mechanism is provided with a push rod 9, and the outer side of the push rod 9 is fixedly installed on the inner side of the cleaning scraper 10. The inner side of the push rod 9 passes through the interior of the stirring rod 8. A return spring 11 is provided between the inner side of the push rod 9 and the inner wall of the stirring rod 8. A sealing ring 12 is fixedly installed at the outer opening of the stirring rod 8, and the inner side of the sealing ring 12 is attached to the surface of the push rod 9.

[0029] After the polyurethane material is removed after foaming, the drive motor 6 continues to drive the rotating rod 7 to rotate. At the same time, under the pressure of the return spring 11 inside the stirring rod 8, the outer push rod 9 moves outward to squeeze the cleaning scraper 10. The cleaning scraper 10 adheres to the inner wall of the foaming chamber 2 under the action of the push rod 9. Meanwhile, under the action of the sealing ring 12, the sealing between the push rod 9 and the stirring rod 8 is maintained, which can prevent the inner wall from sticking and avoid material waste.

[0030] Example 3: Figures 1-6The technical solution shown, based on Embodiment 2, discloses the following to address the problem of poor mixing effect after adding chemical additives to polyurethane materials: a driven rod 14 is provided at the upper end of the foaming chamber 2, and an intermittent communication mechanism is provided at the upper end of the driven rod 14. The intermittent communication mechanism is provided with a disc 15, and the lower end of the disc 15 is fixedly installed on the upper surface of the driven rod 14. The intermittent communication mechanism is provided with a transmission belt 13, and the left side of the transmission belt 13 is sleeved on the upper surface of the rotating rod 7 through a pulley, and the right side of the transmission belt 13 is sleeved on the middle surface of the driven rod 14 through a pulley. A positioning bolt 16 is fixedly installed on the upper left side of the disc 15, and a grooved rod 17 is sleeved on the surface of the positioning bolt 16. A sealing plate 18 is fixedly installed on the right side of the grooved rod 17, and the right side of the sealing plate 18 is fitted into the interior of the additive addition port 4.

[0031] When adding chemical agents to the foaming chamber 2 through the additive addition port 4, the chemical agents are first blocked by the sealing plate 18 inside the additive addition port 4. As the rotating rod 7 rotates, the driven rod 14 can be driven to rotate through the linkage of the transmission belt 13. The disk 15 at the upper end of the driven rod 14 pushes the grooved rod 17 through the positioning bolt 16. The grooved rod 17, as the sealing plate 18 on the right side is limited inside the additive addition port 4, can make the sealing plate 18 move back and forth, thereby achieving the effect of intermittent addition of chemical agents. This makes the polyurethane material and chemical agents mix more evenly and saves the time required for foaming.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
