[0024] 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.

[0025] like Figures 1-5 As shown, a high-pressure mixing head for a foaming machine includes a mixing head body 1; a nozzle body 11 is installed on the middle of the outer side of the mixing head body 1; a nozzle body 12 is installed at one bottom end of the mixing head body 1; a filter plate 13 is installed inside the nozzle body 11; a pressure ring 14 is slidably connected inside the mixing head body 1; the pressure ring 14 is located above the filter plate 13; a threaded limiting ring 15 is threadedly connected to the outer top of the nozzle body 11; during operation, the filter plate 13 is first placed in the groove inside the nozzle body 11, then the pressure ring 14 is placed on top of the filter plate 13, and the threaded limiting ring 15 is installed on the nozzle body 11 by rotation. 1. On the outside, the pressure ring 14 is fixed, and then the raw material is injected into the nozzle body 11 by jumping over the threaded limit ring 15. The raw material is filtered by the filter plate 13 and enters the mixing head body 1 of the foaming machine for mixing. It is then sprayed out through the nozzle body 12. When the raw material enters the mixing head body 1 of the foaming machine through the nozzle body 11, there may be some impurities and crystals. Long-term use may cause blockage of the nozzle body 12 and affect the normal operation of the mixing head body 1 of the foaming machine. Therefore, when the raw material is injected into the mixing head body 1 of the foaming machine, it is filtered by the filter plate 13, which greatly reduces the impact of impurities and crystals in the raw material on the normal operation of the mixing head body 1 of the foaming machine.

[0026] like Figures 2-3As shown in Figure 5, multiple sets of spring rotating rods 2 are hinged to the top outer side of the filter plate 13; a connecting strip 21 is fixedly connected to the outer side of the spring rotating rod 2; a retaining ring 22 is fixedly connected to the outer side of the pressure ring 14 near the connecting strip 21; multiple sets of limiting blocks 23 are fixedly connected to the top of the filter plate 13; the limiting blocks 23 are located on the side of the connecting strip 21 near the pressure ring 14; during operation, when the pressure ring 14 is installed on the top of the filter plate 13, the pressure ring 14 gradually approaches the filter plate 13, and the retaining ring 22 on the outer side of the pressure ring 14 begins to squeeze the connecting strip 21, and the connecting strip 21 begins to rotate outward. When the pressure ring 14 is in complete contact with the filter plate 13, the pressure ring 14 gradually approaches the filter plate 13, and the retaining ring 22 on the outer side of the pressure ring 14 begins to squeeze the connecting strip 21, and the connecting strip 21 begins to rotate outward. When the filter plate 13 is reached, the connecting strip 21 begins to rebound under the influence of the spring rod 2 and is fastened to the outside of the retaining ring 22. The limiting block 23 limits the connecting strip 21. When the nozzle body 11 is working for a long time, impurities and crystals inside the raw material will accumulate on the top of the filter plate 13, and the filter plate 13 needs to be disassembled and cleaned regularly. Therefore, by connecting the retaining ring 22 and the connecting strip 21, when the pressure ring 14 is taken out from the inside of the nozzle body 11, the filter plate 13 is driven away, which simplifies the steps of taking out the filter plate 13 and saves time costs when cleaning the filter plate 13.

[0027] like Figure 1 , 4 As shown, a threaded cylinder 3 is threadedly connected to the outside of the nozzle body 12; a spherical tube 31 is installed inside the threaded cylinder 3; a nozzle 32 is fixedly connected to the outside of the spherical tube 31; the nozzle 32 is located outside the threaded cylinder 3; during operation, the threaded cylinder 3 is installed on the outside of the nozzle body 12 by rotation. When the raw material to be mixed is sprayed out from inside the nozzle body 12, it will be sprayed out through the spherical tube 31 and the nozzle 32. The angle of the spherical tube 31 can be adjusted inside the threaded cylinder 3. When the device is in use, some gaps are relatively small and narrow, so adjusting the angle through the spherical tube 31 inside the threaded cylinder 3 makes it more convenient to fill some relatively small and narrow gaps, further improving the working efficiency of the foaming machine mixing head body 1.

[0028] like Figure 1 As shown, an adjusting handle body 4 is fixedly connected to the end of the foaming machine mixing head body 1 away from the nozzle body 12; an adjusting rod 41 is installed at the end of the adjusting handle body 4 away from the foaming machine mixing head body 1; during operation, the adjusting rod 41 is moved to engage with the adjusting handle body 4 to control the spraying speed and dosage of the foaming machine mixing head body 1. During operation, the required spraying speed and dosage of the foaming agent vary depending on the different usage environments. Adjusting the spraying speed and dosage by adjusting the adjusting handle body 4 can reduce raw material waste and save costs.

[0029] like Figure 4As shown, the bottom of the mixing head body 1 is fixed with a sealing pad 5 close to the gun nozzle body 12; the sealing pad 5 is located outside the gun nozzle body 12; when the threaded cylinder 3 is installed outside the gun nozzle body 12 by rotating, one end of the threaded cylinder 3 will be in close contact with the sealing pad 5; through the use of the sealing pad 5, the connection between the threaded cylinder 3 and the mixing head body 1 of the foaming machine is more closely, which further improves the sealing performance of the threaded cylinder 3 and increases the service life of the threaded cylinder 3.

[0030] As shown in Figure 4 the gun nozzle body 12 is fixed with an inner rubber pad 6 inside away from the mixing head body 1 of the foaming machine; when the threaded cylinder 3 is rotated into the gun nozzle body 12, one end of the spherical pipe 31 will enter the gun nozzle body 12 to press the inner rubber pad 6; the use of the inner rubber pad 6 makes the inner wall of the gun nozzle body 12 not directly contact with the spherical pipe 31, which has a certain protective effect on the surface of the spherical pipe 31 and increases the service life of the spherical pipe 31.

[0031] As shown in Figures 1-2 the top of the threaded limiting ring 15 is fixed with a pipe joint head 7; when the pipeline needs to be connected with the threaded limiting ring 15, the use of the pipe joint head 7 can make the pipeline connection more stable and reliable.

[0032] The working principle is that first, the filter plate 13 is placed in the groove inside the nozzle body 11, then the compression ring 14 is placed on top of the filter plate 13, the threaded limiting ring 15 is installed outside the nozzle body 11 by rotating, the compression ring 14 is fixed, then the raw material is injected into the nozzle body 11 through the threaded limiting ring 15, the raw material is filtered by the filter plate 13 and mixed in the foam machine mixing head body 1, and then sprayed out through the gun nozzle body 12. When the raw material passes through the nozzle body 11 and enters the foam machine mixing head body 1, some impurities and crystals may be generated, which may cause blockage of the gun nozzle body 12 after long-term use, affecting the normal work of the foam machine mixing head body 1. Therefore, when the raw material is injected into the foam machine mixing head body 1, it is filtered by the filter plate 13, greatly reducing the influence of impurities and crystals in the raw material on the normal work of the foam machine mixing head body 1. When the compression ring 14 is installed on top of the filter plate 13, the compression ring 14 gradually approaches the filter plate 13, the clasp ring 22 outside the compression ring 14 starts to squeeze the connecting strip 21, the connecting strip 21 starts to rotate outward, and when the compression ring 14 completely contacts the filter plate 13, the connecting strip 21 is affected by the spring rotating rod 2 and starts to rebound, buckling outside the clasp ring 22, and the limiting block 23 limits the connecting strip 21. When the nozzle body 11 works for a long time, impurities and crystals in the raw material will accumulate on top of the filter plate 13, which needs to be regularly disassembled and cleaned. Therefore, through the connection of the clasp ring 22 and the connecting strip 21, the filter plate 13 is driven away when the compression ring 14 is taken out from the inside of the nozzle body 11, simplifying the steps of taking out the filter plate 13 and saving the time cost of cleaning the filter plate 13. The threaded cylinder 3 is installed outside the gun nozzle body 12 by rotating, when the mixed raw material needs to be sprayed out from the gun nozzle body 12, it is sprayed out through the spherical pipe 31 and the spray head 32. The spherical pipe 31 can adjust the angle inside the threaded cylinder 3. When the device is used, some gaps are small and narrow, so it is more convenient to fill some small and narrow gaps by adjusting the angle of the spherical pipe 31 inside the threaded cylinder 3, further improving the working efficiency of the foam machine mixing head body 1. The adjusting lever 41 is adjusted to buckle the adjusting handle body 4 to work, realizing the speed and dose of the foam machine mixing head body 1. During the working process of the foam machine mixing head body 1, the spraying speed and dose of the foaming agent required are different according to different use environments. The adjusting handle body 4 is adjusted to reduce the waste of raw materials and save costs. When the threaded cylinder 3 is installed outside the gun nozzle body 12 by rotating, one end of the threaded cylinder 3 will be in close contact with the sealing gasket 5. The use of the sealing gasket 5 makes the connection between the threaded cylinder 3 and the foam machine mixing head body 1 more tightly, further improving the sealing performance of the threaded cylinder 3 and increasing the service life of the threaded cylinder 3. When the threaded cylinder 3 is rotated into the gun nozzle body 12, one end of the spherical pipe 31 will enter the gun nozzle body 12 and squeeze the inner rubber pad 6. The use of the inner rubber pad 6,The inner side wall of the gun nozzle body 12 is not directly contacted with the spherical through pipe 31, the surface of the spherical through pipe 31 is protected, and the service life of the spherical through pipe 31 is increased; when the pipeline needs to be connected with the threaded limiting ring 15, the pipeline connection is more stable and reliable through the use of the pipe joint head 7.
