[0023] The utility model will be further explained below in connection with the drawings and examples.
[0024] Please refer to Figs. 1-6 The utility model provides a kind of example: easy-to-clean polyurethane foaming machine includes flat car 1 and stirring barrel 2;It further includes water tank 3, cleaning spray head 4 and No. 1 snap ring 5, flat car 1 is placed with stirring barrel 2, stirring barrel 2 side is fixedly connected with discharge pipe 6, discharge pipe 6 is inserted with hose 7, one end of hose 7 is equipped with high-pressure spray head 8, high-pressure spray head 8 outer side is fixedly connected with limiting ring 9, flat car 1 bottom end is equipped with the water tank 3 of built-in high-pressure water pump, water tank 3 right side is connected with the cleaning spray head 4 passing through flat car 1, high-pressure spray head 8 is sleeved in cleaning spray head outer side, hose 7 outer side is clamped with No. 1 snap ring 5 of bottom end close to limiting ring 9, by installing the water tank 3 of built-in high-pressure water pump in flat car 1 bottom end, with the cleaning spray head of water tank 3 passing through the car plate of flat car 1, by No. 1 snap ring 5 pressing limiting ring 9 top, high-pressure spray head 8 is formed to limit, so that high-pressure spray head 8 is sleeved in cleaning spray head outer side, utilize cleaning spray head to spray high-pressure water column upwards and wash high-pressure spray head 8 inside, No. 1 snap ring 5 can avoid high-pressure spray head 8 because of the upward force generated by cleaning spray head 4 and appear to deviate, such design can be cleaned without disassembling high-pressure spray head 8, improve the efficiency of cleaning, liquid mixed by stirring barrel 2 enters into hose 7 from discharge pipe 6, then is sprayed on building surface after the pressurization of high-pressure spray head 8 and foams.
[0025] Please refer to Figs. 1-4In this embodiment, a support plate 10 is fixedly connected to the top of the flatbed trolley 1. A guide tube 11 passing through the support plate 10 is fixedly connected to the right side of the first retaining ring 5. A pull ring 12 is fixedly connected to the other side of the guide tube 11. The pull ring 12 can drive the guide tube 11 and the first retaining ring 5 to move left and right. A spring 13 is sleeved on the outside of the guide tube 11. One end of the spring 13 is fixedly connected to the support plate 10, and the other end of the spring 13 is fixedly connected to the first retaining ring 5. When the pull ring 12 is pulled, the first retaining ring 5 moves to the right. The spring 13 is pushed to the left, at which point the first retaining ring 5 is removed, making it easy to attach the high-pressure nozzle 8 to the outside of the cleaning nozzle. After the force is released, the spring 13 loses its compression and, under the action of elasticity, pushes the first retaining ring 5 back to its original position, forming a limit at the top of the limiting ring 9. Two symmetrical slots 14 are opened on the right side of the support plate 10. The left side of the pull ring 12 is fixedly connected to a fixed insert 15 that matches the slot 14. The insertion of the insert into the insertion hole can play a limiting role and prevent the first retaining ring 5, which is fixedly connected to the pull ring 12, from shifting.
[0026] Please see Figs. 4-6 In this embodiment, a storage groove 16 is provided at the bottom of the flatbed trolley 1. A mounting base 17 with its top end tightly attached to the inside of the storage groove 16 is fixedly connected to the top of the water tank 3. The mounting base 17 has four anchoring holes. The water tank 3 is fixed in the storage groove 16 by screws passing through the anchoring holes. The design of the storage groove 16 can expand the installation space of the water tank 3, thereby increasing the size of the water tank 3, while preventing the water tank 3 from contacting the ground. A bucket cover 18 is fitted onto the top of the mixing bucket 2. A feed pipe 19 is fixedly connected to the bucket cover 18. An outer fixing device is provided inside the mixing bucket 2. A stirring shaft 20 is fixedly connected to the stirring block. A motor 21 with its output end connected to the stirring shaft 20 is installed on the bucket cover 18. The motor 21 drives the stirring shaft 20 to rotate. The raw materials are put into the mixing bucket 2 through the feed pipe 19. The stirring shaft 20 drives the stirring block to mix the two liquid raw materials. A second retaining ring 22 with its top tightly attached to the limiting ring 9 is fixedly connected to the outside of the bucket cover 18. The hose 7 is clamped in the second retaining ring 22. When it is not necessary to use the high-pressure nozzle 8 to spray polyurethane foam, the hose 7 and the high-pressure nozzle 8 are fixed next to the mixing bucket 2 by the second retaining ring 22.
[0027] When working, the staff first pushes the flatbed cart 1 to the corresponding position, and then pours the raw materials into the mixing tank 2 through the feed pipe 19. Then, the motor 21 is started, and the motor 21 drives the raw materials in the mixing tank 2 to mix and stir. After the mixing is completed, the hose 7 is taken out from the second retaining ring 22, aligned with the plane, and the high-pressure nozzle 8 is started. The high-pressure nozzle 8 pressurizes the mixed raw materials and sprays them onto the surface to form polyurethane foam.
[0028] After spraying is completed, pull ring 12 is pulled, and pull ring 12 moves the first retaining ring 5 to squeeze the spring 13, aligning the high-pressure nozzle 8 with the cleaning nozzle. Then, pull ring 12 is pushed to the left. After the external force is lost, the spring 13 moves the first retaining ring 5 to reset. When the fixing post 15 is inserted into the slot 14, the first retaining ring 5 is locked above the limiting post to form a fixed position. The cleaning nozzle is started, and the high-pressure water pump draws water from the water tank 3 and sprays it out to rinse the inside of the high-pressure nozzle 8.
[0029] Through the above steps, a water tank 3 with a built-in high-pressure water pump is installed at the bottom of the flatbed trolley 1. The cleaning nozzle of the water tank 3 passes through the flatbed trolley 1 and is pressed against the upper part of the limiting ring 9 by the first retaining ring 5, thus restricting the high-pressure nozzle 8. This allows the high-pressure nozzle 8 to be fitted onto the outside of the cleaning nozzle. The cleaning nozzle sprays a high-pressure water jet upward to rinse the inside of the high-pressure nozzle 8. The first retaining ring 5 can prevent the high-pressure nozzle 8 from shifting due to the upward force generated by the cleaning nozzle 4. This design allows the high-pressure nozzle 8 to be cleaned without disassembling it, improving the cleaning efficiency and solving the problem that the high-pressure nozzle 8 of the existing polyurethane foaming machine requires a lot of time to disassemble and clean.
