Description

Technical Field

[0001] The present application relates to the field of feeding, in particular to the feeding technology in the stir-frying of hot pot bases, and specifically relates to a quantitative feeding device. Background Art

[0002] Hot pot bases are generally used for the cooking of hot pots. They usually contain a variety of spices and seasonings and are the key seasonings that determine the taste and flavor of hot pots. The production and processing steps of hot pot bases generally include raw material preparation, raw material processing, stir-frying of raw materials, solid filtration, oil-water separation, low-temperature solidification, packaging and storage, etc. Stir-frying of raw materials generally means putting a variety of raw materials into a stir-frying pot for stir-frying. The proportion of raw materials, the order of feeding, and the stir-frying time will all affect the flavor of the hot pot base.

[0003] Currently, when putting raw materials into the stir-frying pot, generally, workers first weigh different raw materials and put them into raw material barrels, then place the raw material barrels at positions that can be recognized by the robotic arm, and finally drive the raw material barrels to move through the robotic arm to put the raw materials into the stir-frying pot. This feeding method requires manual quantitative weighing, with low weighing accuracy and low weighing efficiency. Moreover, the weighed raw materials need to be manually transferred to positions that can be recognized by the robotic arm, which is rather troublesome. Summary of the Invention

[0004] To solve the above-mentioned defects of related prior arts, the present application provides a quantitative feeding device that can accurately and efficiently weigh raw materials and does not require manual transfer of the weighed raw materials, having strong practicability.

[0005] To achieve the above object, the present invention adopts the following technologies: A stir-frying feeding device, comprising: A material storage mechanism, including a plurality of material storage bins and material storage plates with a quantity matching that of the material storage bins. The material storage bins are distributed in a circumferential array and are all rotatably arranged around the central axis of the array. The distances between the two side surfaces of the material storage bins and the central axis of the array are equal. The upper and lower surfaces of the material storage bins are both open. The material storage plates are respectively slidably arranged on the lower surfaces of the material storage bins. The two side surfaces of the material storage plates are coplanar with the corresponding two side surfaces of the material storage bins respectively. The material storage plates rotate around the central axis of the array following the material storage bins; The temporary storage mechanism includes multiple temporary storage bins and temporary storage plates with a quantity matching that of the temporary storage bins. The temporary storage bins are all arranged on the periphery of the central axis of the array, and the distances from the central axis of the array are adjustable. The temporary storage bins are all rotatably arranged around the central axis of the array. The distances between the two side faces of the temporary storage bins and the central axis of the array are equal. The upper parts of the rear end plates of the temporary storage bins are all penetrated with first feeding ports and are provided with first feeding plates whose outer shapes match the first feeding ports. The lower end surfaces of the first feeding ports are coplanar with the upper surfaces of the storage plates. The distances between the first feeding plates and the central axis of the array are adjustable. The upper and lower surfaces of the temporary storage bins are both open. The temporary storage plates are arranged in a circumferential array around the central axis of the array and are respectively in sliding contact with the lower surfaces of the temporary storage bins. The two side faces of the temporary storage plates are respectively coplanar with the two corresponding side faces of the temporary storage bins. The first feeding plates and the temporary storage plates both rotate around the central axis of the array following the temporary storage bins.

[0006] The beneficial effects of the present invention are as follows: 1. Multiple storage bins and temporary storage bins are provided.

Detailed implementation manners

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following describes the embodiments of the present invention in detail with reference to the accompanying drawings. However, the embodiments described herein are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0019] As Figure 1 shown, this embodiment provides a quantitative feeding device, including a storage mechanism and a temporary storage mechanism.

[0020] Specifically, as Figure 1 and Figure 2 shown, the storage mechanism includes a plurality of storage bins 1 and storage plates 11 with a quantity matching that of the storage bins 1. In this example, a total of six storage bins 1 and six storage plates 11 are provided; the storage bins 1 are arranged in a circumferential array, the central axis of the array is parallel to the height direction of the storage bins 1, the storage bins 1 are all rotatably arranged around the central axis of the array, the distances between the two side surfaces of the storage bins 1 and the central axis of the array are equal, the upper and lower surfaces of the storage bins 1 are both open, the storage plates 11 are slidably arranged on the lower surfaces of the corresponding storage bins 1 one by one, the two side surfaces of the storage plates 11 are coplanar with the two side surfaces of the corresponding storage bins 1 respectively, and the storage plates 11 rotate around the central axis of the array following the storage bins 1.

[0021] Specifically, as Figure 1 and Figure 3 shown, the temporary storage mechanism includes a plurality of temporary storage bins 2 and temporary storage plates 21 whose quantity matches that of the temporary storage bins 2. In this embodiment, a total of six temporary storage bins 2 and six temporary storage plates 21 are provided; the temporary storage bins 2 are all arranged on the periphery of the central axis of the array and the distance from the central axis of the array is adjustable. The temporary storage bins 2 are all rotatably arranged around the central axis of the array and their height directions are all parallel to the central axis of the array. The distances between the two side surfaces of the temporary storage bins 2 and the central axis of the array are equal. The upper parts of the rear end plates of the temporary storage bins 2 are all penetrated with first feeding ports 22 and first feeding plates 23 whose outer shapes match the first feeding ports 22 are provided. The lower end surfaces of the first feeding ports 22 are coplanar with the upper surfaces of the storage plates 11. The distances between the first feeding plates 23 and the central axis of the array are adjustable. The upper and lower surfaces of the temporary storage bins 2 are both open. The temporary storage plates 21 are arranged in a circumferential array around the central axis of the array and are in sliding contact with the lower surfaces of the temporary storage bins 2 one by one. The two side surfaces of the temporary storage plates 21 are coplanar with the two corresponding side surfaces of the temporary storage bins 2 respectively. The first feeding plates 23 and the temporary storage plates 21 both rotate around the central axis of the array following the temporary storage bins 2.

[0022] During operation, different raw materials are separately added into different storage bins 1 from the upper surfaces of different storage bins 1 through manual or external conveying devices. Each storage bin 1 is used to store different raw materials. Since the storage bin 1 can rotate around the central axis of the array, only one feeding point can be set, avoiding the need to supplement different raw materials from different feeding points each time. After feeding, rotate the storage bin 1. In this example, since both the storage bin 1 and the temporary storage bin 2 are set to six, it is necessary to rotate the storage bin 1 until it is aligned with the temporary storage bin 2 one by one. After alignment, reduce the distance between the temporary storage bin 2 and the central axis of the array and the distance between the first feeding plate 23 and the central axis of the array, that is, move the temporary storage bin 2 and the first feeding plate 23 towards the central axis of the array. When the first feeding plate 23 contacts the front end plate of the storage bin 1 and the temporary storage bin 2 contacts the storage plate 11, stop moving the first feeding plate 23, continue to move the temporary storage bin 2, and make the storage plate 11 slide on the lower surface of the storage bin 1, so that the storage plate 11 and the temporary storage bin 2 move synchronously while in contact. Since the two side surfaces of the temporary storage plate 21 are coplanar with the two side surfaces of the corresponding temporary storage bin 2 respectively, when there is a gap between the front end of the storage plate 11 and the front end plate of the storage bin 1, the raw materials in the storage bin 1 will fall into the temporary storage bin 2 from this gap. After respectively putting a specified amount of raw materials into the temporary storage bin 2, move the temporary storage bin 2, the first feeding plate 23, and the storage plate 11 back to their original positions, that is, complete the quantitative feeding into the storage bin 1. At this time, rotate the temporary storage bin 2 to make the temporary storage bin 2 located directly above the frying pan in turn. When the temporary storage bin 2 is located above the frying pan, increase the distance between the temporary storage bin 2 and the central axis of the array, that is, move the temporary storage bin 2 in the direction away from the central axis of the array, so that there is a gap between the front end of the temporary storage plate 21 and the front end plate of the temporary storage bin 2, and the raw materials in the temporary storage bin 2 will fall into the frying pan. While adding the raw materials in the temporary storage bin 2 into the frying pan, the storage bin 1 with insufficient storage can be rotated to the feeding point of the storage bin 1 for replenishment, and the two do not interfere with each other during the working process.

[0023] Preferably, as Figures 2 to 4 shown, the rear end plate of the storage bin 1 is set as an inclined plate, and the distance between its upper end and the central axis of the array is less than the distance between its lower end and the central axis of the array. Such a design can minimize the area of the lower surface of the storage bin, so that the temporary storage bin 2 and the storage plate 11 only need to move a small distance, and all the raw materials in the storage bin 1 can fall out from the gap between the front end of the storage plate 11 and the front end plate of the storage bin 1. The part from the first feeding port 22 to the lower surface of the temporary storage bin 2 in the rear end plate of the temporary storage bin 2 is set as an inclined plate, and the distance between its upper end and the central axis of the array is less than the distance between its lower end and the central axis of the array. Such a design can minimize the area of the lower surface of the temporary storage bin, so that the temporary storage bin 2 only needs to move a small distance, and all the raw materials in the temporary storage bin 2 can fall out from the gap between the front end of the temporary storage plate 21 and the front end plate of the temporary storage bin 2.

[0024] Preferably, asFigures 2 to 4 As shown, the front end plate of the storage bin 1 is set as an arc-shaped plate, and the central axis of the front end plate of the storage bin 1 is coaxial with the central axis of the array; the first feeding plate 23 is set as an arc-shaped plate, and the concave shape thereof matches the outer side shape of the front end plate of the storage bin 1; the front end face of the storage plate 11 is set as an outwardly convex arc surface, and its shape matches the outer side shape of the front end plate of the storage bin 1; the lower end of the first feeding port 22 is set as an arc-shaped edge, and its shape matches the outer side shape of the front end plate of the storage bin 1; with such a design, when no material is fed into the frying pan and the storage bin 1 is rotated, the first feeding plate 23 is in sliding contact with or has a small distance from the front end plate of the storage bin 1, and the lower end of the first feeding port 22 is in sliding contact with or has a small distance from the front end face of the storage plate 11, which is more convenient for feeding the temporary storage bin 2.

[0025] Preferably, as Figure 1 and Figure 2 shown, two first mounting brackets 12 are provided below the storage plate 11, first sliding rods 13 are provided on the first mounting brackets 12, the two first sliding rods 13 are parallel to the two side faces of the corresponding first mounting brackets 12 and perpendicular to the central axis of the array, first sliding blocks 14 are slidably sleeved on the first sliding rods 13, first springs 15 are provided between one end of the first mounting brackets 12 close to the central axis of the array and the first sliding blocks 14, the first springs 15 are coaxially sleeved on the first sliding rods 13, the storage plate 11 is respectively arranged on the two first sliding blocks 14 below it, the first springs 15 are always in a compressed state, and when the first sliding blocks 14 contact the end of the first mounting brackets 12 facing away from the central axis of the array, the front end face of the storage plate 11 is located at the front end plate of the storage bin 1; with such a design, when the temporary storage bin 2 contacts the storage plate 11, the movement of the temporary storage bin 2 can drive the storage plate 11 to move, and there is no need for a separate driving device to drive the storage plate 11 to move, and the first spring 15 can drive the storage plate 11 to automatically return to its position.

[0026] Preferably, as Figure 2 and Figure 3As shown in the figure, second mounting brackets 24 are connected to both side surfaces of the temporary storage bin 2. Second sliding rods 25 are provided on the second mounting brackets 24. The second sliding rods 25 are parallel to the corresponding side surfaces of the temporary storage bin 2 and perpendicular to the array central axis. Second sliding blocks 26 are slidably sleeved on the second sliding rods 25. Second springs 27 are connected between the second sliding blocks 26 and one ends of the second mounting brackets 24 facing away from the array central axis. The second springs 27 are coaxially sleeved on the second sliding rods 25. Two first connecting rods 28 are connected to the first feeding plate 23. The two first connecting rods 28 are respectively connected to the corresponding two second sliding blocks 26. The second springs 27 are always in a compressed state. When the second sliding blocks 26 contact the ends of the second mounting brackets 24 close to the array central axis, the first feeding plate 23 is located within the first feeding port 22. With such a design, when the temporary storage bin 2 moves, the first feeding plate 23 moves along with the temporary storage bin 2. When the first feeding plate 23 contacts the front end plate of the storage bin 1, if the temporary storage bin 2 continues to move, at this time, the first feeding plate 23 no longer moves due to the obstruction of the storage bin 1, and there is no need for a separate driving device to drive the first feeding plate 23 to move, and the second spring 27 can drive the first feeding plate 23 to automatically return to its original position.

[0027] Preferably, as Figure 3 and Figure 4 shown in the figure, two second connecting rods 29 are connected to the temporary storage plate 21. The two second connecting rods 29 are respectively connected to a third mounting bracket 210 and a fourth mounting bracket 211. The third mounting bracket 210 and the fourth mounting bracket 211 are respectively located on both sides of the temporary storage bin 2. An electric screw rod 212 is provided on the third mounting bracket 210. The driving shaft of the electric screw rod 212 is parallel to the side wall of the temporary storage bin 2 and perpendicular to the array central axis. The electric screw rod 212 is in threaded cooperation with a first fitting block 213. A third sliding rod 214 is provided on the fourth mounting bracket 211. The third sliding rod 214 is parallel to the electric screw rod 212. A third sliding block 215 is slidably fitted on the third sliding rod 214. The first fitting block 213 and the third sliding block 215 are both connected to the temporary storage bin 2. The electric screw rod 212 is used to drive the temporary storage bin 2 to move.

[0028] Preferably, as Figure 3 and Figure 5As shown, the device further includes a feeding mechanism, which includes a plurality of feeding bins 3. In this example, a total of three feeding bins 3 are provided; the feeding bins 3 are arranged in a circumferential array around the central axis of the array. The upper ends of the feeding bins 3 are open. The feeding bins 3 respectively correspond to multiple horizontal axes. Each of the horizontal axes is perpendicular to and intersects the central axis of its corresponding feeding bin 3, and each of the horizontal axes is perpendicular to the vertical connection line between the intersection point of the horizontal axis and the central axis of the feeding bin 3 and the central axis of the array. The feeding bins 3 are respectively rotatably arranged around their corresponding horizontal axes. The upper parts of the rear ends of the feeding bins 3 are all penetrated with second feeding ports 31 and are provided with second feeding plates 32 whose shapes match the second feeding ports 31. Specifically, the rear end of the feeding bin 3 refers to the end of the feeding bin 3 close to the central axis of the array; the lower end surface of the second feeding port 31 is coplanar with the upper surface of the temporary storage plate 21. The distance between the second feeding plate 32 and the central axis of the array is adjustable. The front end of the temporary storage plate 21 is set as a convex arc surface, and the rear end of the feeding bin 3 is set as a concave arc plate. The central axes of the front end of the temporary storage plate 21 and the rear end of the feeding bin 3 are both coaxial with the central axis of the array. The distance between the front end of the temporary storage plate 21 and the rear end of the feeding bin 3 is a predetermined value. The predetermined value here should be set small enough so that the temporary storage plate 21 will not touch the feeding bin 3 when it rotates, and the raw materials will not pass through the gap between the front end of the temporary storage plate 21 and the rear end of the feeding bin 3.

[0029] During operation, the feeding bin 3 is used to feed the frying pan, and each feeding bin 3 corresponds to a separate frying pan. The frying pan is arranged below its corresponding feeding bin 3. The feeding bin 3 is used to feed its corresponding frying pan; when adding materials into the feeding bin 3, first rotate the temporary storage bin 2 to align the temporary storage bin 2 containing raw materials with the feeding bin 3; after alignment, increase the distance between the temporary storage bin 2 and the central axis of the array, that is, move the temporary storage bin 2 in the direction of the feeding bin 3. When the temporary storage bin 2 contacts the second feeding plate 32, continue to move the temporary storage bin 2 and make the temporary storage bin 2 move synchronously with the second feeding plate 32. At this time, the front end plate of the temporary storage bin 2 crosses the second feeding port 31, and the raw materials in the temporary storage bin 2 fall into the feeding bin 3; rotate the feeding bin 3 containing raw materials around its corresponding horizontal axis, that is, pour the raw materials in the feeding bin 3 into the frying pan.

[0030] With such a design, when discharging materials from the feeding bin 3, the storage bin 1 can simultaneously feed materials into the temporary storage bin 2; and when the temporary storage bin 2 feeds materials into the feeding bin 3, external mechanical structures or manual labor can be used to replenish materials into the storage bin 1 at the same time, improving the overall discharging efficiency; and multiple feeding bins 3 are provided, which can discharge materials into multiple frying pans; the storage bin 1 feeds materials into the temporary storage bin 2 quantitatively, and the temporary storage bin 2 then feeds materials into the feeding bin 3 quantitatively. The two feeding operations can more accurately control the amount of raw materials finally poured into the frying pan, improving the quality of frying; and when multiple raw materials need to be added into the frying pan at the same time, the raw materials in multiple temporary storage bins 2 can be first added into the same storage bin 1, and then the storage bin 1 is rotated to pour multiple raw materials into the frying pan at the same time, which is relatively convenient to operate.

[0031] Further preferably, as Figure 1 shown, for the convenience of discharging materials, the feeding bin 3 can be set as a cylindrical bin body, and a part of the feeding bin 3 facing the central axis of the array is set as an arc plate recessed inward, and the second feeding port 31 is arranged at the upper end of the arc plate.

[0032] Preferably, as Figure 5 shown, a first fixing plate 33 is connected to the outer wall of the feeding bin 3, two fifth mounting brackets 34 are connected to the first fixing plate 33, fourth sliding rods 35 are provided on both of the two fifth mounting brackets 34, the two fourth sliding rods 35 are arranged in parallel and are both perpendicular to the central axis of the array, the vertical distances between the two fourth sliding rods 35 and the central axis of the array are equal, fourth sliding blocks 36 are slidably sleeved on the fourth sliding rods 35, a third spring 37 is connected between the fourth sliding block 36 and the end of the fifth mounting bracket 34 facing away from the central axis of the array, the third spring 37 is coaxially sleeved on the fourth sliding rod 35, two third connecting rods 38 are connected to the second feeding plate 32, the two third connecting rods 38 are respectively connected to the two fourth sliding blocks 36, and the third spring 37 is always in a compressed state. When the fourth sliding block 36 is located on the fifth mounting bracket 34 close to the central axis of the array, the second feeding plate 32 is located in the second feeding port 31; with such a design, there is no need to separately provide a driving mechanism for the second feeding plate 32, and the second feeding plate 32 can be driven to move synchronously through the temporary storage bin 2, and the third spring 37 is used to drive the second feeding plate 32 to automatically return to its original position.

[0033] Preferably, as Figure 6As shown, a bearing plate 39 is provided below the feeding bin 3. The upper surface of the bearing plate 39 is connected with a first support rod 310. The first support rod 310 is connected with a first support frame 311. A first rotating motor 312 is provided on the first support frame 311. The outer wall of the feeding bin 3 is connected with a second fixing plate 313. Two rotating rods 314 are rotatably connected to the second fixing plate 313. The two rotating rods 314 are coaxially arranged. Specifically, the central axis of the rotating rod 314 can be regarded as the array central axis. One of the rotating rods 314 is coaxially connected with the driving shaft of the first rotating motor 312, and the other rotating rod 314 is rotatably connected to the second fixing plate 313. The first rotating motor 312 is used to drive the feeding bin 3 to rotate.

[0034] Preferably, as Figure 6 and Figure 7 shown, one end of the feeding bin 3 is open and extends inward with a convex ring 315. The convex ring 315 is connected with two guide rods 316 both arranged along the axial direction of the feeding bin 3. The guide rods 316 are connected to the other end of the feeding bin 3. A pushing plate 317 with a plate surface perpendicular to the axial direction of the feeding bin 3 is slidably sleeved on the guide rods 316. The pushing plate 317 matches the shape of the inner wall of the feeding bin 3. A linear cylinder 318 is provided on the first support frame 311. The linear cylinder 318 is arranged between the feeding bin 3 and the array central axis and its driving shaft is perpendicular to and intersects with the array central axis. The driving shaft of the linear cylinder 318 faces the feeding bin 3 and is coaxially connected with a pushing disc 319. With such a design, when pouring the raw materials in the feeding bin 3, the feeding bin 3 can be rotated to a horizontal state and one of its ends faces the array central axis. At this time, the pushing disc 319 is driven to move by the linear cylinder 318. The pushing disc 319 contacts the pushing plate 317 and drives the pushing plate 317 to move along the axial direction of the feeding bin 3. The pushing plate 317 pushes out the raw materials in the feeding bin 3, and the raw materials will not remain in the feeding bin 3.

[0035] Preferably, as Figure 8As shown in the figure, the device further includes a placement plate 4. The placement plate 4 is provided with a plurality of support vertical bars 41. The support vertical bars 41 are all connected with support horizontal bars 42. Above the placement plate 4, there is an installation plate 43. The support horizontal bars 42 are all connected to the installation plate 43. The lower surface of the installation plate 43 is rotatably connected with a rotating column 44 arranged coaxially with the array central axis. The installation plate 43 is provided with a second rotating motor 45. The drive shaft of the second rotating motor 45 is coaxially connected with the rotating column 44. The lower end of the rotating column 44 is coaxially connected with a first rotating disc 46. The first rotating disc 46 is provided with support folding rods 47 whose quantity matches that of the storage bins 1. In this example, there are twelve support folding rods 47. Every two support folding rods 47 are respectively connected to a storage bin 1. The side of the first rotating disc 46 is connected with connection bars 48 whose quantity matches that of the first mounting brackets 12. In this example, there are twelve connection bars 48. The connection bars 48 are respectively connected to the first mounting brackets 12. The second rotating motor 45 is used to drive the storage bins 1 to rotate around the array central axis.

[0036] Preferably, as Figure 9 shown in the figure, the placement plate 4 is provided with a rotating table 49 coaxially with the array central axis. The upper part of the rotating table 49 is coaxially embedded with a third rotating motor 410. The drive shaft of the third rotating motor 410 is coaxially connected upward with a second rotating disc 411. The second rotating disc 411 is connected with connection columns 412 whose quantity matches that of the temporary storage plates 21. The connection columns 412 are all connected with weighing blocks 413. The weighing blocks 413 are all connected with weighing plates 414. The temporary storage plates 21 are all connected to the weighing plates 414. The weighing blocks 413 and the weighing plates 414 are used to weigh the raw materials in the temporary storage bin 2. Specifically, the total weight measured by the weighing blocks 413 and the weighing plates 414 is the sum of the temporary storage bin 2 and its affiliated structures, the temporary storage plates 21 and their affiliated structures, and the raw materials in the temporary storage bin 2. Subtracting the weight of the temporary storage bin 2 and its affiliated structures and the weight of the temporary storage plates 21 and their affiliated structures from the weighed total weight, the weight of the raw materials in the temporary storage bin 2 can be obtained. The specific mechanical structure and circuit structure for weighing in the weighing blocks 413 and the weighing plates 414 belong to the prior art, so they will not be elaborated here too much. The third rotating motor 410 is used to drive the temporary storage bin 2 and the temporary storage plates 21 to rotate around the array central axis.
