Illustratively, the first stirring vanes 11 are provided with a plurality of layers along the axial direction of the first rotating shaft 10, each layer of the first stirring vanes 11 includes a plurality of first transverse vanes provided along the circumferential direction of the first rotating shaft 10, the first transverse vanes are provided with a plurality of first vertical vanes 35, and the first transverse vanes and the first vertical vanes 35 are perpendicular to each other; the second stirring vanes 29 are provided with multiple layers along the axial direction of the second rotating shaft 28, each layer of the second stirring vanes 29 comprises a plurality of second transverse vanes arranged along the circumferential direction of the second rotating shaft 28, a plurality of second vertical vanes 36 are provided on the second transverse vanes, and the second transverse vanes and the second vertical vanes 36 are perpendicular to each other; such design makes the stirring leaf can carry out axial mixing and circumference to the material and mix, makes the material mix more fully.

Exemplarily, the baffle 16 with be equipped with the sealing washer between the hole of dodging, prevent that the material from oozing from the clearance between baffle 16 and the hole of dodging.

Illustratively, water valves for controlling the on-off of water flow are arranged at the water inlet of the first water passing channel, the water inlet of the second water passing channel and the water inlet of the third water passing channel, and the water valves are electrically connected with the controller; therefore, the on-off of water flow is automatically controlled, and the manual labor degree is reduced.

When in use, the first raw material and the second raw material are poured into the inner barrel 1 through the first feeding hole, the third raw material is poured into the outer barrel 2 through the second feeding hole, the controller controls the first motor 3 to be started, the second motor 4, the third motor 14 and the hydraulic cylinder 19 to be closed, the inner barrel stirring device axially mixes and circumferentially mixes the first raw material and the second raw material, namely primary stirring mixing is carried out, the first scraper 23 continuously scrapes the raw materials attached to the side wall of the inner barrel 1, when the stirring time reaches the set time, the controller respectively controls the second motor 4, the third motor 14 and the hydraulic cylinder 19 to be started, the primarily mixed materials in the inner barrel 1 enter the conveying pipe 12 to be stirred and mixed for the second time, so that the first raw material and the second raw material are mixed more uniformly, and the secondarily mixed materials are conveyed downwards, the materials in the outer barrel 2 are prevented from entering the inner barrel 1, meanwhile, the push rod of the hydraulic cylinder 19 contracts to drive the top plate 17 to move downwards, the baffle plate 16 is driven to move downwards, materials after secondary mixing flow into the outer barrel 2 through the material conveying channel 15, the second motor 4 drives the outer gear 8 to rotate, the outer barrel cover 7 is driven to rotate, the outer barrel stirring device is enabled to axially mix and circumferentially mix the second raw materials and the third raw materials, the second scraper 26 continuously scrapes the raw materials attached to the inner side wall of the outer barrel 2, the raw materials are output from the discharge port after mixing is finished, automatic stirring and mixing of the first raw materials, the second raw materials and the third raw materials are completed, the push rod of the hydraulic cylinder 19 is controlled by the controller to stretch out to close the material conveying channel 15, and the first motor 3, the second motor 4 and the third motor 14 are controlled to be closed.

Therefore, the first raw material and the second raw material are stirred and mixed twice, then the material mixed by the first raw material and the second raw material and the third raw material are stirred and mixed, meanwhile, the raw materials attached to the inner side wall of the inner barrel 1 and the inner side wall of the outer barrel 2 are scraped off by the first scraper 23 and the second scraper 26, so that the first raw material, the second raw material and the third raw material are sequentially mixed, the mutual influence of the reaction of the three is effectively prevented, the quality of a finished product is improved, the raw materials are fully mixed by axially mixing and circumferentially mixing, the mixing uniformity of the first raw material and the second raw material is improved, meanwhile, the utilization rate of the raw materials is improved, and the material in the conveying pipe 12 enters the outer barrel 2 for a plurality of times and a small amount through the arrangement of the hydraulic cylinder 19, so that the mixing uniformity of the materials is further improved; meanwhile, one device realizes the mixing of the three raw materials, the use is convenient, and the occupied space is small; in addition, the invention can also be used for mixing two raw materials, thereby realizing three times of mixing of the two raw materials.

When cleaning, the controller respectively controls the first motor 3, the second motor 4, the third motor 14 and the hydraulic cylinder 19 to be opened, so that the push rod of the hydraulic cylinder 19 is contracted to drive the top plate 17 to move downwards, the baffle plate 16 is driven to move downwards, the first scraper 23, the second scraper 26 and the third scraper 31 are driven to rotate to respectively scrape off materials on the side wall of the inner barrel 1, the wall of the inner barrel 1 of the outer barrel 2 and the wall of the outer barrel 2 of the inner barrel 1, meanwhile, the controller controls the water valve to be opened, so that a water source respectively enters the first water passing channel, the second water passing channel and the third water passing channel, water flows respectively from the first spray nozzle 24, the second spray nozzle 27, the third spray nozzle 32, the fourth spray nozzle 33 and the fifth spray nozzle 34, waste materials of the inner barrel 1 flow into the outer barrel 2 through the material conveying channel 15 and then flow out from the material outlet, and cleaning of polyurethane foaming equipment with a cleaning function is.

Therefore, the waste materials are scraped off from the side walls through the scraping plates, and the side walls are sprayed through the spray heads, so that all the side walls in the polyurethane foaming equipment with the cleaning function can be cleaned, the polyurethane foaming equipment is convenient to use and high in cleaning efficiency, and the manual labor intensity is low.
