[0023] Among them, the limiting structure includes a plurality of vertically arranged slide bars 21, which are fixedly connected to the inner wall of the material equalizing device 6, and a plurality of slide grooves 20 slidably connected to the slide bars 21 are opened on the outer side of the ring piece 18, and the limiting structure prevents the ring piece 18 from rotating.

[0024] The blowing structure includes two arc-shaped air supply pipes 14 distributed in an array with the second rotating disk 11 as the center, and a first one-way valve 27 and a second one-way valve 28 are installed at one end of the arc-shaped air supply pipe 14.

The second one-way valve 28 is one-way from the arc-shaped air supply pipe 14 to the elliptical plate 9. The first one-way valve 27 is connected to the inside of the arc-shaped air supply pipe 14. The first one-way valve 27 is one-way to the inside of the arc-shaped air supply pipe 14. For conduction, a constant pressure hole 29 is opened at one end of the arc-shaped air supply pipe 14 away from the first one-way valve 27 and the second one-way valve 28, and a magnetic piston column 30 is slidably connected inside the arc-shaped air supply pipe 14.

The air inside the arc-shaped air supply pipe 14 will be discharged from the second one-way valve 28 to the inside of the elliptical plate 9, and discharged from the bottom of the baffle 10, and blown to the ingredients, so that the baffle 10 spreads the paste or fine ingredients such as ketchup more evenly through the airflow, and after the second telescopic rod 16 is separated from the magnetic piston column 30, the magnetic piston column 30 will be reset under the traction of the elastic rope 31, and the interior of the arc-shaped air supply pipe 14 will be replenished with air again through the first one-way valve 27.

[0026] Among them, the clamping structure includes a third telescopic rod 32 arranged horizontally, and the third telescopic rod 32 is fixedly connected to an arc-shaped clamping strip 33 at one end close to the chain conveyor belt 1, and an infrared sensing device 34 is fixedly connected to the middle part of one of the arc-shaped clamping strips 33. When the chain conveyor belt 1 transports the pizza baking tray 2 between the two clamping structures, the infrared sensing device 34 senses the pizza baking tray 2 and controls the third telescopic rod 32 to extend, so as to clamp the pizza baking tray 2 through the arc-shaped clamping strip 33.

[0027] Among them, a through hole 36 for ventilation is opened on the top of the material balancing device 6, and an N-shaped block 35 is fixedly connected to the lower end of the first telescopic rod 5. The first telescopic rod 5 is fixedly connected to the top of the material balancing device 6 through the set N-shaped block 35.

[0028] Working principle: When in use, the pizza baking tray 2 containing pizza crust is placed on the chain conveyor 1. One or more stands 4 are installed on the outer side of the chain conveyor 1 according to needs. That is, the ingredients are fed into the middle of the pizza baking tray 2 through the feeding device. The feeding device can be a screw conveyor to quantitatively transport the ingredients to the pizza. The stand 4 is installed behind the feeding device. If multiple feeding devices are used to feed different ingredients respectively, multiple equalizing devices 6 are also used to evenly disperse the different ingredients. Specifically, the third telescopic rod 32 is first in a retracted state, and the feeding mechanism feeds the ingredients into the middle of the crust. When the chain conveyor 1 transports the pizza baking tray 2 between the two clamping structures, the infrared sensing device 34 senses the pizza baking tray 2 and controls the third telescopic rod 3 2 is extended, and the pizza baking pan 2 is clamped by the arc-shaped clamping strip 33. Then the first telescopic rod 5 is extended again to push the material distribution device 6 to approach the pizza baking pan 2. The second telescopic rod 16 is in an extended state by default. The insertion rod 12 at the bottom of the material distribution device 6 is inserted into the ingredients, but there is a distance of 0.5-1.5 cm from the crust. Then the driving structure is controlled, that is, the motor 22 drives the first gear 23 to rotate clockwise, and the second gear 24 is driven by the first gear 23 to rotate slowly counterclockwise. The second gear 24 drives the connecting plate 13 connected to the inner gear ring 25 to rotate slowly counterclockwise. Finally, the second rotating disk 11 rotates rapidly clockwise, and the elliptical plate 9 rotates slowly counterclockwise. The insertion rod 12 is inserted into the ingredients. The rapid rotation will disperse the ingredients. At the same time Some of the materials will be blocked by the insertion rod 12 and will not be thrown out, while the thrown out ingredients will be blocked by the baffle 10 and will be evenly distributed on the pizza under the slow rotation of the baffle 10. When the oval plate 9 rotates, the arc-shaped air supply pipe 14 will also move together, and the magnet 26 will attract the magnetic piston column 30 inside the arc-shaped air supply pipe 14, so that the magnetic piston column 30 is close to the second one-way valve 28. At the same time, the elastic rope 31 will also be stretched, and the air inside the arc-shaped air supply pipe 14 will be discharged from the second one-way valve 28 to the inside of the oval plate 9, and discharged from the bottom of the baffle 10, blowing towards the ingredients, so that the baffle 10 spreads the paste or fine ingredients such as tomato sauce more evenly through the airflow, and the baffle 10 is arranged along the oval shape of the oval plate 9. When the elliptical plate 9 rotates, small pieces of ingredients will pass through the gap between the baffle 10 and the pizza and remain on the pizza, while large pieces of ingredients gather in the middle and are broken again by the impact of the rapidly rotating plug rod 12, so that the ingredients on the pizza are evenly spread. After the ingredients are evenly spread, the second telescopic rod 16 contracts to lift the top plate 17 and the bottom plate 7 upward as a whole, and the ingredients remaining on the outside of the plug rod 12 will be scraped off by the first turntable 8, and the ingredients on the outside of the baffle 10 will also be scraped off by the elastic rubber sleeve 37. The airflow continuously blown out from the exhaust groove 15 will also prevent the ingredients from being blocked at the bottom of the exhaust groove 15. Finally, the first telescopic rod 5 contracts and resets, and the third telescopic rod 32 contracts. Driven by the chain conveyor belt 1, the pizza baking tray 2 is transported to the next process.

[0029] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.
