Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0023] The specific embodiments are given below.

[0024] Please refer to Figures 1-3As shown, a high-pressure foaming machine cleaning device includes a top cover 11 and a scraper 16, the top cover 11 is fixedly connected to a drive motor 12; the middle part of the top cover 11 is rotatably connected to a drive seat 14, a synchronous belt 15 is installed between the output end of the drive motor 12 and the drive seat 14, the top of the drive seat 14 is fixedly connected to a support tube 13, and a drive assembly that can lift a support arm 24 is installed on the support tube 13, the interior of the support tube 13 is slidably connected to the support arm 24, the bottom end of the support arm 24 is fixedly connected to a cross bar 25, and the scraper 16 is installed at the end of the cross bar 25; the drive assembly includes a lifting motor 21, the lifting motor 21 is fixed to the top of the support tube 13, the middle part of the support tube 13 is rotatably connected to a screw rod 22, the screw rod 22 is fixed to the output end of the lifting motor 21, and the screw rod A threaded seat 23 is installed on 22, and the threaded seat 23 is fixedly connected to the top end of the support arm 24; when in use, the top cover 11 is installed on the tank body of the foaming machine, and the driving motor 12 drives the driving seat 14, the support arm 24, the cross bar 25 and the scraper 16 through the synchronous belt 15 to rotate, and the scraper 16 is used to scrape the residue inside the tank body of the foaming machine to achieve the effect of automatic cleaning. After the cleaning is completed, the lifting motor 21 drives the screw rod 22 to rotate, and the screw rod 22 and the threaded seat 23 installed on the surface move, thereby driving the threaded seat 23, the support arm 24, the cross bar 25 and the scraper 16 to rise and fall. During foaming, it can receive the scraper 16 at the top of the tank body, thereby reducing the situation where the scraper 16 is immersed in the raw material during foaming, and thereby reducing the situation where the scraper 16 remains on the scraper 16.

[0025] Further, such as Figures 2-4 As shown, a water pump 31 is fixedly connected to the top cover 11, an output end of the water pump 31 is fixedly connected to an elastic hose 32, an end of the cross bar 25 is fixedly connected to a support 33, a plurality of nozzles 34 are fixedly connected to the support 33, and the elastic hose 32 and the nozzle 34 are fixedly connected; when in use, clean water can be drawn by the water pump 31 and pressurized to be injected into the elastic hose 32, and then the nozzle 34 is used to spray it onto the inner wall of the tank, thereby improving the cleaning effect and reducing the residue. The driving motor 12 is a servo motor, which rotates the rotating seat for multiple turns and then rotates in the opposite direction to reduce damage to the elastic hose 32.

[0026] Further, such as Figure 5As shown, the inside of the crossbar 25 is provided with a sliding groove 41, the sliding groove 41 is slidably connected with a rack 42, the side of the crossbar 25 is rotatably connected with a rotating arm 44, the bottom end of the rotating arm 44 and the rack 42 are correspondingly fixedly connected with a cam 45, the scraper 16 is provided with two, the two scrapers 16 are rotatably connected on the upper and lower sides of the crossbar 25 through shafts, the end of the shaft is fixedly connected with a gear 43, the gear 43 and the rack 42 are engaged; the rack 42 and the side wall of the sliding groove 41 are fixedly connected with a spring 5, the rotating connection of the rotating arm 44 is provided with a torsional spring; in use, when the crossbar 25 moves to the upper side of the tank, the crossbar 25 is pressed downward, then the cam 45 at the end of the rotating arm 44 pushes the rack 42 to move, the movement of the rack 42 makes the gear 43 rotate, and then the scraper 16 rotates to be stored, after the crossbar 25 moves downward, the spring 5 and the torsional spring make the scraper 16 expand, so that the two scrapers 16 can be rotated and expanded to increase the scraping area, so that the scraping can be conveniently carried out.

[0027] Further, as shown in Figure 5 The top end of the rotating arm 44 is rotatably connected with a first pulley 61, and one end of the rack 42 close to the cam 45 is rotatably connected with a second pulley 62; in use, the first pulley 61 and the second pulley 62 can conveniently reduce the friction between the rotating arm 44 and the top cover 11, and the second pulley 62 can reduce the friction between the cam 45 and the end of the rack 42, so as to conveniently push the rack 42 to move.

[0028] Further, as shown in Figures 4-5 The side of the scraper 16 is fixedly connected with a rubber strip 7, which can improve the adhesion to the inner side wall of the foaming machine tank, thereby improving the scraping effect.

[0029] The working principle is that, in use, the driving motor 12 drives the driving base 14, the supporting arm 24, the cross rod 25 and the scraper 16 to rotate through the synchronous belt 15, and the scraper 16 scrapes the residues in the inside of the tank of the foaming machine to realize the automatic cleaning function. After the cleaning is completed, the lifting motor 21 drives the screw rod 22 to rotate, the screw rod 22 and the threaded seat 23 installed on the surface move, and then drive the threaded seat 23, the supporting arm 24, the cross rod 25 and the scraper 16 to lift. When foaming, the scraper 16 can be collected to the top of the tank, so that the situation that the scraper 16 is immersed in the raw materials during foaming can be reduced, and then the situation that residues are left on the scraper 16 can be reduced. The water pump 31 can extract clean water and inject the clean water into the elastic hose 32 under pressure, and then the nozzle 34 sprays the clean water to the inner wall of the tank, so that the cleaning effect can be improved, and the situation that residues are left can be reduced. When the driving motor 12 is a servo motor, the rotating seat rotates for several rounds and then reverses, so that the situation that the elastic hose 32 is damaged can be reduced. When the cross rod 25 moves to the upper part of the tank, the cross rod 25 is pressed to rotate downward, and then the cam 45 at the end of the rotating arm 44 presses and drives the rack 42 to move. The movement of the rack 42 drives the gear 43 to rotate, and then drives the scraper 16 to rotate to collect the scraper 16. After the cross rod 25 moves downward, the scraper 16 is expanded under the action of the spring 5 and the torsional spring. In this way, the two scrapers 16 can rotate and expand to increase the scraping area, so that the scraping can be facilitated. The first pulley 61 and the second pulley 62 can reduce the friction between the rotating arm 44 and the top cover 11. The second pulley 62 can reduce the friction between the cam 45 and the end of the rack 42, and facilitate the movement of the rack 42.
