Four circumferentially distributed scraping strips 54 are fixedly connected to the outer wall of the cleaning frame 53. A card slot 55 is provided at the center of the inner wall of the bottom surface of the cleaning frame 53.

[0024] Further as Figure 3 and Figure 4 As shown, it is worth mentioning that the anti-blocking component 6 includes a box body 61, which is fixedly connected to the inner surface of the feed barrel 2. The inner wall of the bottom surface of the box body 61 is rotatably connected to a rotating shaft 62. The top end of the rotating shaft 62 rotates through the top surface of the box body 61 and the outer surface is fixedly connected to a spiral blade 63. The outer surface of the rotating shaft 62 located inside the box body 61 is fastened with a worm gear 64. The inner wall on one side of the box body 61 is rotatably connected to a worm 65 meshing with the worm gear 64. The outer wall on one side of the worm 65 rotates through the outer wall on one side of the box body 61 and the outer surface of the feed barrel 2 and is coaxially fixedly connected to a rotating handle 66.

[0025] Further as Figure 1 、 Figure 2 and Figure 4 As shown, it is worth mentioning that the bottom surface of the movable plate 9 is fixedly connected to the motor 10, the output end of the motor 10 is coaxially fixedly connected to the stirring rod 11, the bottom end of the stirring rod 11 rotates through the top inner wall of the tank body 1, and the outer surface of the stirring rod 11 located inside the tank body 1 is fixedly connected to multiple groups of stirring blades 12 distributed in an alternating manner.

[0026] Further as Figure 1 、 Figure 2 and Figure 4 As shown, it is worth mentioning that the top surface of the transverse section of the L-shaped plate 4 is fixedly connected to the cylinder 13, the output end of the cylinder 13 slides through the bottom surface of the transverse section of the L-shaped plate 4 and is fixedly connected to the top surface of the movable plate 9, and the bottom end of the stirring rod 11 is coaxially fixedly connected to a block 14 that is adapted to the slot 55.

[0027] Further as Figure 2 As shown, it is worth mentioning that a gap is set between the bottom surface of the cleaning frame 53 and the inner wall of the bottom end of the tank body 1 to facilitate the discharge of the foamed material from the discharge pipe 3. The scraper 54 is conical and one end of the cone is in contact with the inner surface of the tank body 1. The bottom surface of the scraper 54 fits with the inner wall of the bottom end of the tank body 1, and the inner surface of the tank body 1 is scraped and cleaned by the rotating scraper 54.

[0028] Further as Figure 1 、 Figure 2 and Figure 4As shown, it is worth mentioning that the tank body 1 is coaxially arranged with the motor 10, the rotation diameter of the stirring blade 12 is smaller than the inner diameter of the cleaning frame 53, so as to avoid the stirring blade 12 being interfered with by the cleaning frame 53 when rotating, and a sealing ring is provided at the junction of the stirring rod 11 and the tank body 1 to prevent the material inside the tank body 1 from splashing out.

[0029] In summary: when the foaming equipment is in use, the raw materials are first put into the tank body 1 through the feed barrel 2, and then the motor 10 is turned on to drive the stirring rod 11 to rotate, and the stirring rod 11 drives multiple groups of stirring blades 12 to rotate, stirring and foaming the input raw materials. After the foaming is completed, the motor 10 is turned off and the solenoid valve on the discharge pipe 3 is opened. The foamed material is discharged through the discharge pipe 3 to complete the foaming operation. When the raw material is blocked inside the feed barrel 2, the staff can turn the handle 66 to drive the worm 65 to rotate. Under the meshing action, the worm 65 drives the worm gear 64 to rotate, and the worm gear 64 then drives the rotating shaft 62 and the spiral blade 63 to rotate, thereby stirring the blocked raw materials so that the raw materials can fall smoothly into the tank body 1. The operation is simple, and effectively avoids the problem of easy clogging of the feed pipe when a large amount of raw materials is put in at one time.

[0030] After the material is discharged, the inside of the tank body 1 needs to be cleaned. At this time, the control cylinder 13 pushes the movable plate 9. Through the cooperation of the slide groove 7 and the slider 8, the cylinder 13 pushes the movable plate 9 to drive the motor 10 to move downward, and the motor 10 drives the stirring rod 11 to move downward, thereby pushing the block 14 to insert into the slot 55. Then turn on the motor 10 again. With the cooperation of the arc-shaped slider 52 and the annular groove 51, the motor 10 drives the cleaning frame 53 to rotate through the stirring rod 11, thereby driving the scraper 54 to scrape and clean the inner surface of the tank body 1. At the same time, cleaning water is injected into the tank body 1 through the feed barrel 2 to flush the inner surface of the tank body 1, and the scraped material is flushed out from the discharge pipe 3, thereby improving the cleaning effect of the inside of the tank body 1. After cleaning, the equipment can be reset, which effectively avoids the problem that the material inside the foaming equipment is easy to adhere to and difficult to clean.

[0031] The motor 10 can be purchased on the market. The motor 10 is equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so it will not be repeated in the specification.
