The connecting disk 13 is also fixedly connected to a blowing structure for inflating the inside of the elliptical plate 9.

[0033] When in use, the pizza baking tray 2 containing the pizza crust is placed on the chain conveyor 1. One or more stands 4 are installed on the outside of the chain conveyor 1 as needed. That is, ingredients are fed into the middle of the pizza baking tray 2 through a feeding device.

[0034] Among them, the driving structure includes a top plate 17, and a ring piece 18 is provided on the outer side of the top plate 17. The top plate 17 and the ring piece 18 are fixedly connected together by a number of connecting blocks 19. The gap between 17 and 18 is used for ventilation.

[0035] In this embodiment, the motor 22 drives the first gear 23 to rotate clockwise, and the second gear 24 rotates slowly counterclockwise under the drive of the first gear 23. The second gear 24 drives the connecting disk 13 connected to the inner gear ring 25 to rotate slowly counterclockwise. Finally, the second turntable 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. 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.

[0036] Among them, the top of the material equalizing device 6 is fixedly connected to two vertically arranged second telescopic rods 16, the lower end of the second telescopic rod 16 is fixedly connected to the top of the top plate 17, the outer side of the baffle 10 is provided with an elastic rubber sleeve 37, and the top of the elastic rubber sleeve 37 is fixedly connected to the bottom of the chassis 7. When the second telescopic rod 16 contracts, the top plate 17 and the chassis 7 are lifted upward as a whole, and the ingredients remaining on the outside of the insertion 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.

[0037] Among them, the limiting structure includes several vertically arranged sliding bars 21, which are fixedly connected to the inner wall of the material balancing device 6. Several sliding grooves 20 slidably connected to the sliding bars 21 are opened on the outer side of the ring piece 18. The limiting structure prevents the ring piece 18 from rotating.

[0038] Among them, the blowing structure includes two arc-shaped air supply pipes 14 distributed in an array with the second turntable 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 passes through the connecting disk 13, and the arc-shaped air supply pipe 14 is connected to the interior of the elliptical plate 9 through the second one-way valve 28. 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 interior of the arc-shaped air supply pipe 14. The first one-way valve 27 is one-way to the interior of the arc-shaped air supply pipe 14. For guidance, 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. A magnetic piston column 30 is slidably connected to the inside of the arc-shaped air-supply pipe 14. Two symmetrically distributed magnets 26 are fixedly connected to the bottom of the ring piece 18. The magnets 26 are located on the outside of the arc-shaped air-supply pipe 14.

[0039] In this embodiment, as the elliptical plate 9 rotates, the arc-shaped air supply pipe 14 will also move along with it, and the magnet 26 will attract the magnetic piston column 30 inside the arc-shaped air supply pipe 14, causing the magnetic piston column 30 to approach 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 elliptical plate 9, and discharged from the bottom of the baffle 10, blowing toward 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 disengages 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.

[0040] Among them, the clamping structure includes a horizontally arranged third telescopic rod 32, 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, clamping the pizza baking tray 2 through the arc-shaped clamping strip 33.

[0041] Among them, a through hole 36 for ventilation is opened on the top of the material balancing device 6, and the lower end of the first telescopic rod 5 is fixedly connected to the N-shaped block 35. The first telescopic rod 5 is fixedly connected to the top of the material balancing device 6 through the set N-shaped block 35.

[0042] 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 outside of the chain conveyor 1 as needed. 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 feed the ingredients to the pizza in a quantitative manner. 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 pizza 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 bar 33. Then the first telescopic rod 5 is extended again, pushing the material distribution device 6 to approach the pizza baking pan 2. The second telescopic rod 16 is in the 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 disk 13 connected to the inner gear ring 25 to rotate slowly counterclockwise. Finally, the second turntable 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 elliptical 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 elliptical 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 elliptical shape of the elliptical 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 insertion rod 12, so that the ingredients on the pizza are evenly distributed. After the ingredients are evenly spread, the second telescopic rod 16 contracts, and the top plate 17 and the bottom plate 7 are lifted upward. The ingredients remaining on the outside of the insertion 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.

[0043] 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 common means well known to those skilled in the art.

[0044] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
