Description

Technical Field

[0001] This utility model belongs to the technical field of yogurt cereal cap production equipment, and in particular relates to a cereal cap feeding device. Background Technology

[0002] To enrich the texture of yogurt, a cereal lid is usually placed upside down on the yogurt cup to hold cooked oatmeal, nuts, dried fruit, and other ingredients. When eating, these ingredients are then poured into the yogurt to ensure they remain crisp.

[0003] In the prior art, patent document CN202022749714.6 discloses a cup-type oatmeal filling device, which includes two support plates. An electric push rod is fixed to the top of each support plate, and a fixed plate is fixed to the telescopic end of each electric push rod. Each fixed plate has a first sliding hole. A filling box is fixedly connected to one end of both fixed plates. A fixed rod is located above each fixed plate. A filling machine body is located at the bottom of the filling box. A limit plate is fixed to the outer surface of the filling machine body. A second sliding hole is located on the upper surface of each limit plate. The bottom of each fixed rod passes through the first and second sliding holes sequentially. A groove is formed on the upper surface of the support plate, and two springs are fixed inside the groove. A clamping block is fixed to one end of each spring that is close to each other. A filling cup is located inside the groove, directly below the filling machine body. The electric push rod causes the fixed plate to move the filling box up and down, allowing the oatmeal solids to be injected into the filling cup through the filling machine body, thus preventing the oatmeal from spilling.

[0004] However, during filling, the filling cup needs to be placed into the groove first and wait for filling. After filling is completed, the filling cup containing oatmeal needs to be removed before the next filling cup can be placed in, which is inefficient. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model provides a grain cover feeding device that can prevent material spillage during the feeding process and facilitates the removal and placement of the grain cover.

[0006] In order to achieve the purpose of this utility model, the following solution is proposed: A grain feeding device is disposed below a plurality of quantitative feeding cylinders arranged in a circumferential array. The feeding device includes: The rotating assembly includes a turntable with multiple vertically penetrating feeding holes arranged in a circular array. The bottom surface of the turntable is provided with a guide nozzle with an inverted conical structure corresponding to each feeding hole. The projection of the quantitative feeding cylinder on the turntable falls on the distribution trajectory of the feeding holes. The outer circumference of the turntable is provided with guide grooves arranged in a circular array that are perpendicular to the axis of the feeding holes and correspond one by one. A U-shaped seat is provided at the outer end of the guide groove, and the opening of the U-shaped seat faces the corresponding guide groove. A limiting member for opening and closing the feeding hole is slidably provided in each guide groove, and one end of the limiting member passes through the horizontal part of the U-shaped seat. The conveying assembly is arranged below the turntable along the tangential direction of the feeding hole distribution trajectory. It includes a conveyor belt for conveying the grain cover, with side plates on both sides. Guide rods are vertically arranged on the outer wall of the outer side plate. Slot holes are provided on both sides of the area where the two guide rods are located. U-shaped plates are passed through the guide rods. One end of each of the two arms of the U-shaped plate passes through the corresponding slot holes to limit the grain cover. The pushing component, located on the outside of the turntable and corresponding to the horizontal part of the U-shaped plate, includes a linear mechanism. Its output end is provided with a vertically arranged push plate. The projection of the push plate in the direction of the side plate falls into the limiting member and the U-shaped plate.

[0007] Furthermore, the top surface of the turntable is provided with an annular groove, the feeding hole is located in the annular groove, and the lower end of the quantitative feeding cylinder is correspondingly located in the annular groove.

[0008] Furthermore, the limiting component includes a limiting plate, the outer end of which is provided with a horizontally extending movable rod that passes through the horizontal part of the U-shaped seat. A first spring is sleeved on the movable rod, one end of which abuts against the outer side of the horizontal part of the U-shaped seat, and the other end abuts against the end plate at the outer end of the movable rod. The top surface of the limiting plate is provided with a through hole at the end facing the movable rod. When the through hole is coaxial with the feeding hole, it is used to connect the feeding hole.

[0009] Furthermore, a set of guide rods are arranged parallel to each other and spaced apart, respectively corresponding to both sides of the push plate. The horizontal part of the U-shaped plate passes through the guide rods. A second spring is provided on the outer sleeve of the guide rod. One end of the second spring abuts against the outer wall of the side plate located on the outside, and the other end abuts against the inner wall of the horizontal part of the U-shaped plate.

[0010] Furthermore, the strip hole has a stepped hole structure, with its large end facing one side of the conveyor belt, and the ends of the two support arms on both sides of the U-shaped plate are respectively provided with protrusions that are adapted to the large end of the strip hole.

[0011] The beneficial effects of this utility model are as follows: Feeding holes are arranged in a circular array on the turntable. A guide nozzle with an inverted cone structure is set at the lower end of the feeding holes to prevent material from spilling during the feeding process. A limiting component is used to block or connect the bottom of the feeding holes. Blocking facilitates material retrieval, while connecting facilitates feeding. The grain cover is limited during the feeding process to ensure accurate feeding. After feeding is completed, the limitation on the grain cover is released to make it easy to pick up and put down the grain cover. This saves time and improves work efficiency.

Detailed Implementation

[0023] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0024] like Figures 1-9As shown, this embodiment provides a grain lid feeding device, located below multiple quantitative feeding cylinders 1 arranged in a circumferential array, for feeding various ingredients into the grain lid. This embodiment uses three quantitative feeding cylinders 1 as an example, with their axes evenly distributed within a 180° range, so that the included angle between adjacent quantitative feeding cylinders 1 is 60°. Oat grains, nuts, and dried fruits are respectively loaded into different quantitative feeding cylinders 1, allowing the materials to pass through and be fed into the quantitative feeding cylinders 1. The feeding device includes a rotating component 10, a conveying component 20, and a pushing component 30. The rotating component 10 is used to acquire materials, the conveying component 20 is used to convey the grain lid 2, and the pushing component 30 is used to feed the materials in the rotating component 10 into the grain lid 2.

[0025] Specifically, such as Figures 1-3 As shown, the rotating assembly 10 includes a turntable 11, a U-shaped seat 14, a limiting member 15, and a guide nozzle 16. The turntable 11 is arranged horizontally, and a rotating shaft driven by a rotary motor is provided at the center of its bottom. An annular groove 111 is concentrically provided on the top surface of the turntable 11. Multiple feeding holes 12 are arranged in a circular array in the annular groove 111. In this embodiment, four are used as an example. The feeding holes 12 are arranged vertically and penetrate the upper and lower surfaces of the turntable 11 for feeding materials into the turntable 12.

[0026] The turntable 11 has a guide groove 13 recessed on its outer periphery. The length direction of the guide groove 13 is perpendicular to the axis direction of the feeding hole 12, and each feeding hole 12 corresponds to one guide groove 13. A U-shaped seat 14 is provided for each guide groove 13, and the opening direction of the U-shaped seat 14 faces downward towards the guide groove 13, so that the two arms of the U-shaped seat 14 are connected to the outer periphery of the turntable 11.

[0027] like Figure 2 As shown, a limiting member 15 is provided for each guide groove 13. One end of the limiting member 15 is slidably connected to the guide groove 13, and the other end is inserted through the horizontal part of the corresponding U-shaped seat 14. It is used to block the feeding hole 12 or connect the feeding hole 12. When the feeding hole 12 is blocked, the feeding hole 12 is used to receive the material. When the feeding hole 12 is connected, it is used to receive the material in the feeding hole 12 and put it into the grain cover 2.

[0028] The limiting component 15 includes a limiting plate 151, a moving rod 152, and a first spring 153. The shape of the limiting plate 151 is adapted to the inner wall shape of the guide groove 13, and the limiting plate 151 is slidably disposed in the guide groove 13. The moving rod 152 is disposed at one end of the limiting plate 151 facing the horizontal part of the U-shaped seat 14, and the outer end of the moving rod 152 passes through the corresponding horizontal part of the U-shaped seat 14. A circular plate is provided at one end of the moving rod 152 passing through the horizontal part of the U-shaped seat 14. The first spring 153 is sleeved on the moving rod 152, with one end of the first spring 153 abutting against the outer wall of the horizontal part of the U-shaped seat 14 and the other end abutting against the circular plate. A vertical through hole 154 is provided on the limiting plate 151, and the diameter of the through hole 154 is adapted to the diameter of the feeding hole 12. like Figure 4 As shown, when the first spring 153 is in a free state, one end of the limiting plate 151 abuts against the inner wall of the horizontal part of the U-shaped seat 14, the through hole 154 is offset from the feeding hole 12, and the end of the limiting plate 151 facing the guide groove 13 blocks the feeding hole 12 so that the material enters the feeding hole 12.

[0029] To prevent grain from scattering outwards as it enters the grain cover 2, a guide nozzle 16 with an inverted conical structure is provided at the lower end of each feeding hole 12, and the diameter of the small end of the guide nozzle 16 is smaller than the diameter of the grain cover 2.

[0030] like Figure 1 , Figure 4 As shown, the conveying assembly 20 is located below the turntable 11 and tangent to the distribution trajectory of the feeding holes 12. The conveying assembly 20 includes a conveyor belt 21, side plates 22, guide rods 23, and U-shaped plates 24. The conveyor belt 21 is located below the distribution trajectory of the feeding holes 12, and the center line of the distribution trajectory of the feeding holes 12 is tangent to the long axis of the conveyor belt 21. It is used to convey the grain cover 2, and the axis of the conveyed grain cover 2 is perpendicular to the long axis of the conveyor belt 21. There is one side plate 22 on each side along the length of the conveyor belt 21.

[0031] The guide rod 23 is vertically disposed on the outer wall of the side plate 22 located on the outer side. Two guide rods 23 are arranged in parallel and spaced apart. A strip hole 221 is provided on the side plate 22 located on the outer side, which passes through both sides.

[0032] The horizontal portion of the U-shaped plate 24 passes through the guide rod 23, and the two arms of the U-shaped plate 24 slide through the corresponding strip hole 221. A second spring 231 is sleeved on the guide rod 23. One end of the second spring 231 abuts against the outer wall of the corresponding side plate 22, and the other end abuts against the inner wall of the horizontal portion of the U-shaped plate 24. When the U-shaped plate 24 is not subjected to external force, the second spring 231 is in a free state, and the end of the U-shaped plate 24 facing the strip hole 221 is located inside the strip hole 221. When the horizontal portion of the U-shaped plate 24 is pushed horizontally by external force, the two arms of the U-shaped plate 24 extend into the top of the conveyor belt 21 to block the conveying of the grain cover 2 and limit the conveying of one grain cover 2 below the corresponding feeding hole 12, so that the material in the feeding hole 12 is put into the corresponding grain cover 2.

[0033] like Figure 1 , Figures 5-8 As shown, the pushing assembly 30 includes a linear mechanism 31 and a push plate 32. The linear mechanism 31 is fixed to a frame, and its output end faces the direction of the turntable 11. The push plate 32 is vertically arranged at the output end of the linear mechanism 31, with the upper end of the push plate 32 corresponding to one end of the moving rod 152 passing through the horizontal circular plate of the U-shaped seat 14, and the lower end corresponding to the center line of the two blades 23. In use, the linear mechanism 31 drives the push plate 32 to move, so that the upper and lower ends of the push plate 32 push the circular plate of the moving rod 152 and the horizontal part of the U-shaped plate 24 respectively. On the one hand, the through hole 154 is coaxial with the feeding hole 12 to connect the feeding hole 12 so that the material in the feeding hole 12 falls out. On the other hand, the two arms of the U-shaped plate 24 pass through the corresponding strip hole 221 so that the grain cover 2 remains directly below the corresponding feeding hole 12 during the material falling out.

[0034] After feeding is completed, the push plate 32 is reset so that the U-shaped plate 24 is reset under the action of the second spring 231, so that the next grain cover 2 moves to the front of the area where the two shaped holes 221 are located.

[0035] Preferred, such as Figure 9 As shown, to prevent one end of the U-shaped plate 24 corresponding to the strip hole 221 from moving out of the strip hole 221 when the U-shaped plate 24 is reset, a boss 241 is provided at the end of the support arm of the U-shaped plate 24, and the strip hole 221 is set as a stepped hole structure, so that the large end of the strip hole 221 faces the side where the conveyor belt 21 is located, so that the shape of the boss 241 matches the shape of the large end of the strip hole 221.

[0036] The specific usage process is as follows: The quantitative feeding cylinder 1 contains a certain amount of material. The turntable 11 is started so that each feeding hole 12 passes under each quantitative feeding cylinder 1 in sequence, so that different materials are fed into the feeding hole 12 in sequence.

[0037] After the first feeding cylinder 12 has passed the lower end of the three quantitative feeding cylinders 1, the conveyor belt 21 is started so that the grain cover 2 moves between the areas corresponding to the two shaped holes 221. When the grain cover 2 is in place, the feeding cylinder 12 that has completed the feeding is exactly above the grain cover 2. The speed between the two can be adjusted according to the rotation speed of the turntable 11 and the conveying speed of the conveyor belt 21 to meet the requirements. The prior art will not be described in detail here.

[0038] Then, the linear mechanism 31 is activated to drive the push plate 32 to move. The upper end of the push plate 32 pushes the moving rod 152 to move so that the through hole 154 is coaxial with the feeding cylinder 12, so that the material in the feeding hole 12 falls vertically downward. The lower end of the push plate 32 limits the two sides of the grain cover 2 to prevent the grain cover 2 from moving during the grain falling, thereby realizing automatic feeding.

[0039] After feeding is completed, the linear mechanism 31 drives the push plate 32 to enter the return stroke. At this time, on the one hand, the moving rod 152 drives the limiting plate 151 to extend and retract outward along the guide groove 13 under the action of the first spring 153, so that the through hole 154 is misaligned with the feeding hole 12, and the limiting plate 151 blocks the feeding hole 12 again to prepare for the next feeding; on the other hand, the U-shaped plate 24 moves away from the side plate 22 under the action of the second spring 231, and the protrusions 241 at the ends of the two side arms of the U-shaped plate 24 enter the strip hole 221 to release the restriction on the grain cover 2 containing the material.

[0040] The above description is merely a preferred embodiment of this utility model and does not imply its uniqueness or limitation. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
