[0001] This application is a divisional application of the application filed on February 13, 2025, with application number 2025101589346 and invention title "An Automated Uniform Feeding Device for Food". Technical Field

[0002] This invention relates to the field of feeding device technology, and in particular to an automated uniform feeding device for food. Background Technology

[0003] Automated food production is an important development direction. For example, in the pizza production process, the pizza needs to be placed inside the baking pan, then sauce, cheese, vegetables and meat are evenly sprinkled on the pizza, and finally it is transported to the oven for baking via a chain conveyor belt.

[0004] Currently, the process of sprinkling toppings on pizzas is done manually, which is time-consuming, labor-intensive, inefficient, and prone to spilling onto the conveyor belt. Therefore, an automated device is needed to ensure that pizzas are evenly topped. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the background art by proposing an automated uniform feeding device for food.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An automated food feeding device includes a chain conveyor belt. A pizza pan to be fed is placed on top of the chain conveyor belt. Mounting seats are fixedly connected to both outer walls of the chain conveyor belt. A vertical frame is mounted above the chain conveyor belt. The bottom ends of the vertical frame are fixedly connected to two mounting seats. A vertically mounted first telescopic rod is fixedly connected to the middle of the vertical frame. A feeding device is fixedly connected to the lower end of the first telescopic rod. Clamping structures are fixedly connected to both sides of the vertical frame. A base is rotatably connected to the bottom of the feeding device. A first turntable is rotatably connected to the middle of the base. An elliptical plate is mounted above the base. A second turntable is mounted above the first turntable. The turntable has several evenly distributed baffles fixedly connected to the lower end of the elliptical plate. The baffles pass through the chassis and are slidably connected to the chassis. The lower end of the second turntable has several insert rods fixedly connected to it. The lower ends of the insert rods pass through the first turntable and are slidably connected to it. The baffles have exhaust grooves inside. The elliptical plate has a hollow structure. The exhaust grooves are connected to the interior of the elliptical plate. The top of the elliptical plate is fixedly connected to a connecting plate. The middle part of the connecting plate is rotatably connected to the outer side of the second turntable. The top of the connecting plate is equipped with a drive structure that drives the second turntable and the connecting plate to rotate in opposite directions. An air blowing structure that inflates the elliptical plate is also fixedly connected to the connecting plate.

[0007] Furthermore, the driving structure includes a top plate, with an annular plate on the outer side of the top plate. The top plate and the annular plate are fixedly connected together by several connecting blocks. A limit structure is provided on the outer side of the annular plate. A motor is fixedly connected to the middle of the top plate. The output shaft of the motor passes through the top plate and is fixedly connected to the middle of the second turntable. A first gear is fixedly connected to the output shaft of the motor. A second gear meshes with the outer wall of the first gear. The shaft of the second gear is rotatably connected to the top plate. An internal gear ring is fixedly connected to the top of the connecting disc. The inner side of the internal gear ring meshes with the outer wall of the second gear.

[0008] Furthermore, the top of the material distribution device is fixedly connected to two vertically arranged second telescopic rods, the lower ends of the second telescopic rods are fixedly connected to the top of the top plate, and an elastic rubber sleeve is fitted on the outer side of the baffle, the top of the elastic rubber sleeve is fixedly connected to the bottom of the chassis.

[0009] Furthermore, the limiting structure includes several vertically arranged slide bars, which are fixedly connected to the inner wall of the material equalization device, and several sliding grooves that are slidably connected to the slide bars are opened on the outer side of the ring plate.

[0010] Furthermore, the air-blowing structure includes two arc-shaped air-supplying pipes arranged in an array with the second turntable as the center. One end of each arc-shaped air-supplying pipe is equipped with a first one-way valve and a second one-way valve. The second one-way valve passes through the connecting plate. The arc-shaped air-supplying pipe is connected to the interior of the elliptical plate through the second one-way valve. The second one-way valve allows unidirectional flow from the arc-shaped air-supplying pipe to the elliptical plate. The first one-way valve is connected to the interior of the arc-shaped air-supplying pipe and allows unidirectional flow to the interior of the arc-shaped air-supplying pipe. A constant pressure hole is opened at the end of the arc-shaped air-supplying pipe away from the first and second one-way valves. A magnetic piston column is slidably connected inside the arc-shaped air-supplying pipe. Two symmetrically distributed magnets are fixedly connected to the bottom of the ring plate. The magnets are located outside the arc-shaped air-supplying pipe. An elastic rope is fixedly connected to the end of the magnetic piston column. The end of the elastic rope away from the magnetic piston column is fixedly connected to the constant pressure hole.

[0011] Furthermore, the constant pressure hole is located on the side indicated by the rotation direction of the connecting disc.

[0012] Furthermore, the clamping structure includes a horizontally arranged third telescopic rod, with an arc-shaped clamping strip fixedly connected to one end of the third telescopic rod near the chain conveyor belt, and an infrared sensing device fixedly connected to the middle of one of the arc-shaped clamping strips.

[0013] Furthermore, the top of the material equalization device is provided with a through hole, and the lower end of the first telescopic rod is fixedly connected to an N-shaped block. The first telescopic rod is fixedly connected to the top of the material equalization device through the provided N-shaped block.

[0014] Compared with existing technologies, the present invention has the following advantages: 1. Through the air blowing structure, as the elliptical plate rotates, the arc-shaped air supply pipe also moves along with it. The magnet will attract the magnetic piston inside the arc-shaped air supply pipe, causing the magnetic piston to move closer to the second one-way valve. At the same time, the elastic rope will be stretched, and the air inside the arc-shaped air supply pipe will be discharged from the second one-way valve into the interior of the elliptical plate and discharged from the bottom of the baffle, blowing towards the ingredients. This allows the baffle to spread paste-like or fine ingredients such as tomato sauce more evenly through the airflow. After the second telescopic rod disengages from the magnetic piston, the magnetic piston will reset under the pull of the elastic rope, and the interior of the arc-shaped air supply pipe will be replenished with air again through the first one-way valve. 2. Through the set drive structure, the motor drives the first gear to rotate clockwise, and the second gear rotates slowly counterclockwise under the drive of the first gear. The second gear drives the connecting plate connected to the internal gear ring to rotate slowly counterclockwise. Finally, the second turntable rotates rapidly clockwise, and the oval plate rotates slowly counterclockwise. The insert rod is inserted into the ingredients. The rapid rotation will disperse the ingredients. At the same time, some materials will be blocked by the insert rod and will not be thrown out. The thrown-out ingredients will be blocked by the baffle and evenly distributed on the pizza under the slow rotation of the baffle. 3. With the oval plate and baffles set up, the baffles are arranged along the ellipse of the oval plate. When the oval plate rotates, small pieces of toppings will pass through the gap between the baffles and the pizza and remain on the pizza, while large pieces of toppings gather in the middle and are broken again by the impact of the rapidly rotating stick, so that the toppings on the pizza are evenly distributed. In summary, the present invention uses a second turntable to rotate rapidly clockwise and an elliptical plate to rotate slowly counterclockwise. This causes the insert rods on the ingredient pile to rotate rapidly, which disperses the ingredients. The thrown-out ingredients are blocked by the baffle, and the air blowing structure blows air towards the bottom of the baffle, thereby evenly dispersing the ingredients, including sauces, side dishes, and cheese, on the crust.

[0020] In use, the pizza pan 2 containing the pizza dough is placed on the chain conveyor belt 1. One or more uprights 4 are installed on the outside of the chain conveyor belt 1 as needed. That is, the ingredients are fed into the center of the pizza pan 2 through the feeding device. The feeding device can be a screw conveyor to deliver the ingredients quantitatively onto the pizza. The uprights 4 are installed behind the feeding device. A mixture including sauce, toppings and cheese can be fed into the pizza pan through one feeding device and then evenly distributed by the mixing device 6. Alternatively, multiple feeding devices can be used to feed different ingredients separately, and multiple mixing devices 6 can be used to evenly distribute the different ingredients separately.

[0021] The drive structure includes a top plate 17, with an annular piece 18 on the outer side of the top plate 17. The top plate 17 and the annular piece 18 are fixedly connected together by several connecting blocks 19. The gap between 17 and 18 is for ventilation. A limiting structure is provided on the outer side of the annular piece 18. A motor 22 is fixedly connected to the middle of the top plate 17. The output shaft of the motor 22 passes through the top plate 17 and is fixedly connected to the middle of the second turntable 11.

The inner side of the internal gear ring 25 meshes with the outer wall of the second gear 24.

[0022] 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 internal gear ring 25 to rotate slowly counterclockwise. Finally, the second turntable 11 rotates rapidly clockwise, and the elliptical plate 9 rotates slowly counterclockwise. The insert rod 12 is inserted into the ingredients. The rapid rotation will disperse the ingredients, and some materials will be blocked by the insert rod 12 and will not be thrown out. The thrown-out ingredients will be blocked by the baffle 10 and evenly distributed on the pizza under the slow rotation of the baffle 10.

[0023] The top of the material distribution device 6 is fixedly connected to two vertically arranged second telescopic rods 16. The lower end of the second telescopic rods 16 is fixedly connected to the top of the top plate 17. An elastic rubber sleeve 37 is fitted on the outer side of the baffle 10. The top of the elastic rubber sleeve 37 is fixedly connected to the bottom of the chassis 7. When the second telescopic rods 16 retract, the top plate 17 and the chassis 7 are lifted upward as a whole. The material remaining on the outside of the insertion rod 12 will be scraped off by the first turntable 8, and the material on the outside of the baffle 10 will also be scraped off by the elastic rubber sleeve 37.

[0024] The limiting structure includes several vertically arranged slide bars 21, which are fixedly connected to the inner wall of the material equalization device 6. Several slide grooves 20 that are slidably connected to the slide bars 21 are opened on the outer side of the ring plate 18. The limiting structure prevents the ring plate 18 from rotating.

[0025] The air-blowing structure includes two arc-shaped air supply pipes 14 arranged in an array centered on the second turntable 11. A first one-way valve 27 and a second one-way valve 28 are installed at one end of each arc-shaped air supply pipe 14. The second one-way valve 28 passes through the connecting plate 13. The arc-shaped air supply pipe 14 is connected to the interior of the elliptical plate 9 via the second one-way valve 28, allowing unidirectional flow 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, allowing unidirectional flow from the first one-way valve 27 to the interior of the arc-shaped air supply pipe 14. The arc-shaped air supply pipe 14, away from the first one-way valve 27 and the second one-way valve 28, has a constant pressure hole 29. A magnetic piston column 30 is slidably connected inside the arc-shaped air supply pipe 14. Two symmetrically distributed magnets 26 are fixedly connected to the bottom of the ring plate 18. The magnets 26 are located on the outside of the arc-shaped air supply pipe 14. An elastic rope 31 is fixedly connected to the end of the magnetic piston column 30. The end of the elastic rope 31 away from the magnetic piston column 30 is fixedly connected to the constant pressure hole 29. The constant pressure hole 29 is located on the side indicated by the rotation direction of the connecting plate 13.

[0026] In this embodiment, as the elliptical plate 9 rotates, the arc-shaped air supply pipe 14 also moves along with it. The magnet 26 will attract the magnetic piston 30 inside the arc-shaped air supply pipe 14, causing the magnetic piston 30 to move closer 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 into the interior of the elliptical plate 9 and discharged from the bottom of the baffle 10, blowing towards the ingredients. This allows the baffle 10 to spread the paste-like or fine ingredients, such as tomato sauce, more evenly through the airflow. After the second telescopic rod 16 disengages from the magnetic piston 30, the magnetic piston 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.

[0027] The clamping structure includes a horizontally arranged third telescopic rod 32. An arc-shaped clamping strip 33 is fixedly connected to one end of the third telescopic rod 32 near the chain conveyor belt 1. An infrared sensing device 34 is fixedly connected to the middle of one of the arc-shaped clamping strips 33. When the chain conveyor belt 1 transports the pizza pan 2 between the two clamping structures, the infrared sensing device 34 senses the pizza pan 2 and controls the third telescopic rod 32 to extend, clamping the pizza pan 2 through the arc-shaped clamping strip 33.

[0028] The material distribution device 6 has a through hole 36 for ventilation at the top, 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 distribution device 6 through the N-shaped block 35.

[0029] Working principle: In use, the pizza pan 2 containing the pizza dough is placed on the chain conveyor belt 1. One or more uprights 4 are installed on the outside of the chain conveyor belt 1 as needed. This means that ingredients are fed into the center of the pizza pan 2 via a feeding device, which can be a screw conveyor, to quantitatively deliver the ingredients onto the pizza. The uprights 4 are installed behind the feeding device. If multiple feeding devices are used to feed different ingredients, multiple equalizing devices 6 are also used to evenly distribute the different ingredients. Specifically, the third telescopic rod 32 is initially in a retracted state. The feeding mechanism feeds ingredients into the center of the pizza dough. When the chain conveyor belt 1 transports the pizza pan 2 between the two clamping structures, the infrared sensor 34 senses the pizza pan 2 and controls the third telescopic rod 32... 2. The first telescopic rod 5 extends, clamping the pizza pan 2 with the arc-shaped clamping strip 33. Then, the first telescopic rod 5 extends further, pushing the distributing device 6 closer to the pizza pan 2. The second telescopic rod 16 is in the extended state by default. The insert 12 at the bottom of the distributing device 6 is inserted into the ingredients, but at a distance of 0.5-1.5cm from the pizza dough. Then, the drive structure is controlled, that is, the motor 22 drives the first gear 23 to rotate clockwise. The second gear 24, driven by the first gear 23, slowly rotates counterclockwise. The second gear 24 drives the connecting plate 13, which is connected to the internal gear ring 25, to slowly rotate counterclockwise. Finally, the second turntable 11 rotates rapidly clockwise, and the oval plate 9 rotates slowly counterclockwise. The insert 12 is inserted into the ingredients, and the rapid rotation will disperse the ingredients. Some ingredients will be blocked by the insert rod 12 and not thrown out, while the thrown-out ingredients will be blocked by the baffle 10 and evenly distributed on the pizza as the baffle 10 slowly rotates. Simultaneously, as the oval plate 9 rotates, the arc-shaped air supply pipe 14 also moves. The magnet 26 will attract the magnetic piston 30 inside the arc-shaped air supply pipe 14, causing the magnetic piston 30 to move closer to the second one-way valve 28. At the same time, the elastic rope 31 will be stretched, and the air inside the arc-shaped air supply pipe 14 will be discharged from the second one-way valve 28 into the interior of the oval plate 9 and out from the bottom of the baffle 10, blowing towards the ingredients. This allows the baffle 10 to spread paste-like or fine ingredients, such as tomato sauce, more evenly through airflow. Furthermore, the baffle 10 follows the elliptical shape of the oval plate 9... As the oval plate 9 rotates, small pieces of toppings will pass through the gap between the baffle 10 and the pizza and remain on the pizza, while larger pieces of toppings will gather in the center and be broken again by the rapidly rotating insert rod 12, making the toppings evenly distributed on the pizza. After the toppings are evenly spread, the second telescopic rod 16 retracts, lifting the top plate 17 and the base plate 7 as a whole. The toppings remaining on the outside of the insert rod 12 will be scraped off by the first turntable 8, and the toppings on the outside of the baffle 10 will also be scraped off by the elastic rubber sleeve 37. The airflow continuously blowing out of the exhaust vent 15 will also prevent the toppings from clogging the bottom of the exhaust vent 15. Finally, the first telescopic rod 5 retracts and resets, and the third telescopic rod 32 retracts, and the pizza pan 2 is transported to the next process by the chain conveyor belt 1.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
