Description

Technical Field

[0001] This utility model relates to the field of chocolate production and processing technology, and in particular to a device for adding nuts to the surface of chocolate. Background Technology

[0002] Chocolate is a dessert made primarily from cocoa liquor and cocoa butter, boasting a rich and complex flavor profile and a robust aroma. As consumer tastes have evolved, they are no longer satisfied with the conventionally shaped chocolates available on the market. This has led to the emergence of nut-mixed chocolates, often adorned with large nuts (such as pecans and macadamia nuts). These chocolates offer a more refined appearance and allow for greater design flexibility.

[0003] Current technology primarily involves manually placing nuts on designated locations on the chocolate surface. However, this method is inefficient, unsuitable for mass production, and the placement of the nuts cannot be precisely controlled, affecting the aesthetics of the finished chocolate. Furthermore, manual selection cannot remove rotten nuts. Even if humans can visually identify visibly rotten nuts, this method is inefficient and cannot accurately select for nuts with less obvious rot. Placing rotten nuts on the chocolate surface leads to substandard chocolate products and negatively impacts the eating experience. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a device for adding nuts to the surface of chocolate, which can ensure the quality of the nuts added to the surface of chocolate, improve the yield of chocolate production, and increase production efficiency.

[0005] This utility model provides a device for adding nuts to the surface of chocolate, comprising: The feeding section is used to feed the nuts. A sorting section, located on one side of the feeding section, is used to arrange the nuts from the feeding section into at least one straight row. A screening section, located below the dispensing section, is used to screen out rotten kernels from the dispensing section. An array section, located on one side of the screening section, is used to arrange the kernels after screening into at least one straight column. A gripping part is provided above the array part and is configured to be able to move up and down to grip the nuts at the array part and add the nuts to the surface of the chocolate.

[0006] In one embodiment, the dispensing section includes a material cylinder, a stirring component, and a dispensing plate. The material cylinder includes a receiving cavity for receiving nuts from the feeding section. The stirring component is installed in the receiving cavity and is rotatable about the axial direction of the material cylinder to stir the nuts in the receiving cavity.

[0007] In one embodiment, the material draining trough is configured as a straight trough, and the width of the material draining trough is matched with the kernel. When there are two or more material draining troughs, the material draining troughs are parallel to each other.

[0008] In one embodiment, the feed trough is configured to include a plurality of openings, the size of which matches the size of the kernels, the openings being arranged in at least one straight line and spaced apart, and when the openings are arranged in two or more straight lines, the straight lines are parallel to each other.

[0009] In one embodiment, the screening unit includes a first conveyor, a detection unit, a collection unit, and a feeding unit. The first conveyor is located below the distribution plate, the detection unit is located on one side of the first conveyor along its length, the feeding unit is installed at the upper end of the detection unit, and the collection unit is installed on one side of the detection unit along its width. The first conveyor can deliver kernels to the detection unit for detection, and the feeding unit is configured to move relative to the collection unit along the width of the first conveyor to deliver detected rotten kernels into the collection unit.

[0010] In one embodiment, the detection component includes a transparent plate disposed on one side of the length direction of the first conveyor, and the lower end of the transparent plate is provided with an imaging unit and / or an infrared sensing unit for detecting kernels.

[0011] In one embodiment, the screening unit further includes a material guide, which is detachably installed at the lower end of the material distribution plate and communicates with the material leakage trough. The lower end of the material guide is provided with a plurality of openings, the size of which matches the size of the kernel. The openings are arranged in at least one straight line and spaced apart. When the openings are arranged in two or more straight lines, the straight lines are parallel to each other.

[0012] In one embodiment, the array section includes a second conveyor and a third conveyor. The second conveyor is disposed on one side of the screening section, and the third conveyor is disposed on one side of the second conveyor along its length. The third conveyor is capable of moving up and down relative to the second conveyor.

[0013] In one embodiment, the array section further includes at least one material distribution channel, which is located between the screening section and the second conveyor. The material distribution channel includes a first hopper and a second hopper, which are connected and can arrange the nuts in a straight line and deliver them to the second conveyor.

[0026] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0027] like Figure 1 As shown, the chocolate surface nut adding device proposed in this utility model includes: The feeding section 10 is used to feed the nuts. The feeding section 20, located on one side of the feeding section 10, is used to arrange the nuts from the feeding section 10 into at least one straight row. The screening section 30, located below the dispensing section 20, is used to screen out rotten kernels from the dispensing section 20. An array section 40, located on one side of the screening section 30, is used to arrange the kernels after screening by the screening section 30 into at least one column arranged in a straight line. The grasping part 50 is located above the array part 40 and is configured to be able to move up and down to grasp the nuts at the array part 40 and add the nuts to the surface of the chocolate.

[0028] The feeding section 10 enables the feeding of nuts, freeing up manpower and improving feeding efficiency. The sorting section 20 arranges the nuts from the feeding section 10 into a straight line to cooperate with the screening section 30 for nut detection and screening. The straight arrangement helps the screening section 30 remove rotten nuts and avoids blind spots caused by nut stacking, thus preventing rotten nuts from entering the next production process. The array section 40, in conjunction with the gripping section 50, can adjust the arrangement of nuts so that the gripping section 50 can add the nuts to the surface of the chocolate. The overall structure is simple, highly automated, and ensures the quality of the nuts added to the surface of the chocolate, improving the chocolate production yield and increasing production efficiency.

[0029] In an example scheme, such as Figure 1 As shown, the feeding section 10 adopts a bucket elevator, which can lift a large number of nuts to the top of the distributing section 20, and can cooperate with the operation of the distributing section 20 to send the nuts to the distributing section 20 in batches, thereby ensuring the efficiency of the distributing section 20 in arranging nuts.

[0030] In an example scheme, such as Figure 2 As shown, the feeding section 20 includes a material cylinder 21, a stirring component 22, and a feeding plate 23. The material cylinder 21 includes a receiving cavity 211, which extends through the material cylinder 21 along its axial direction. The feeding section 10 can feed nuts through the upper end of the material cylinder 21 into the receiving cavity 211. The stirring component 22 is installed inside the material cylinder 21 and can rotate around the axial direction of the material cylinder 21 to stir the nuts in the receiving cavity 211 and provide power to the nuts. The feeding plate 23 is detachably installed at the lower end of the material cylinder 21 to seal the lower end of the receiving cavity 211. At least one leakage groove 231 is provided on the feeding plate 23, which extends through the material cylinder 21 along its axial direction. The nuts inside the material cylinder 21 can fall into the screening section 30 through the leakage groove 231.

[0031] For example, the stirring component 22 includes a central shaft 221 and at least one blade 222. The central shaft 221 is coaxially arranged with the material cylinder 21. At least one blade 222 is installed on the radial outer wall of the central shaft 221 and moves synchronously with the central shaft 221. Driven by an external power source, the central shaft 221 rotates around its own axis and drives the blade 222 to rotate synchronously, stirring the nuts in the receiving cavity 211 so that the nuts can fall into the screening section 30 through the discharge trough 231.

[0032] Furthermore, such as Figure 2 As shown, the blade 222 is an arc-shaped part, and the end of the blade 222 that is away from the central axis 221 in the radial direction of the central axis 221 is bent toward the side closer to the central axis 221, so that during rotation, the kernels located at the radial edge of the receiving cavity 211 can be pushed toward the side closer to the central axis 221, preventing kernels from accumulating in the receiving cavity 211 and failing to fall into the discharge trough 231.

[0033] For example, such as Figure 2 As shown, at least one discharge trough 231 is a straight trough, and the width of the discharge trough 231 is matched with the size of the kernels so that the kernels can be arranged in a straight line when they fall into the screening section 30 through the discharge trough 231. When there are two or more discharge troughs 231, the discharge troughs 231 are parallel to each other.

[0034] Furthermore, the feed trough 231 is configured to include a plurality of openings, which are arranged in at least one straight line and spaced apart. The size of the openings is matched with the size of the nuts so that a certain interval is maintained between the nuts arranged in the straight line. When the openings are arranged in two or more straight lines, the straight lines are parallel.

[0035] For example, such as Figure 2 As shown, the material distribution plate 23 has a shaft groove 232. The size of the shaft groove 232 matches the size of the central shaft 221. When the central shaft 221 is installed, the lower part of the central shaft 221 passes through the shaft groove 232 and can rotate around its own axis within the shaft groove 232.

[0036] Furthermore, the shaft groove 232 is configured to penetrate the material distribution plate 23 axially along the central shaft 221.

[0037] Furthermore, a bearing is provided in the shaft groove 232 to allow the central shaft 221 to rotate about its own axis within the shaft groove 232.

[0038] Furthermore, the upper end of the material cylinder 21 is provided with a cover plate, on which a slot is provided to cooperate with the central shaft 221, and a feed port is provided to cooperate with the feeding part 10. The upper part of the central shaft 221 can pass through the cover plate and be connected to an external power source. The slot and the shaft groove 232 cooperate to ensure the stability and efficiency of the rotation of the central shaft 221. The feeding part 10 can feed the kernels into the receiving cavity 211 through the feed port.

[0039] For example, the dispensing plate 23 is detachably installed at the lower end of the material cylinder 21, so as to facilitate the replacement of dispensing plates 23 with different specifications of leakage troughs 231 according to the variety and size of the nuts, such as... Figure 2 As shown, a first mounting hole 212 is provided at the lower end of the material cylinder 21, and a second mounting hole 233 is provided on the material distribution plate 23. The first mounting hole 212 and the second mounting hole 233 cooperate to install the material distribution plate 23 to the lower end of the material cylinder 21.

[0040] Furthermore, both the first mounting hole 212 and the second mounting hole 233 are screw holes to facilitate the disassembly and assembly of the material distribution plate 23.

[0041] In an example scheme, such as Figure 3 As shown, the screening unit 30 includes a first conveyor 31, a detection member 32, a collection member 33, and a feeding member 34. The first conveyor 31 is located below the material cylinder 21, more specifically below the distribution plate 23, to receive the kernels leaking from the leakage trough 231. The detection member 32 is located on one side of the length direction of the first conveyor 31. The first conveyor 31 can deliver the kernels to the detection member 32 for detection to determine whether the kernels are rotten. The feeding member 34 is installed on the upper end of the detection member 32. The collection member 33 is located on one side of the width direction of the detection member 32. The feeding member 34 is configured to move relative to the collection member 33 to feed the detected rotten kernels into the collection member 33 for centralized collection.

[0042] For example, the first conveyor 31 is a conveyor belt.

[0043] For example, combined Figure 1 and Figure 3 The detection component 32 includes a transparent plate disposed on one side of the first conveyor 31 along its length, used to support the kernels. The lower end of the transparent plate is equipped with an imaging unit 321 and / or an infrared sensing unit to detect the kernels and determine whether rot has occurred on the surface and inside. In another example, such as... Figure 1 As shown, the imaging unit 321 can also be located above the transparent plate, for example, installed on one side of the material cylinder 21, or installed at the lower end of the material distribution plate 23.

[0044] For example, such as Figure 3As shown, the collecting component 33 is detachably installed on at least one side of the width direction of the first conveyor 31, and the feeding component 34 can move along the width direction of the first conveyor 31 to feed the detected rotten kernels into the collecting component 33.

[0045] Furthermore, the lower end of the collecting component 33 is provided with a pipe that can be connected to an external collection box to collect the rotten kernels in one place, preventing the rotten kernels from overflowing onto the transparent plate when the collecting component 33 is full, thus ensuring the continuity of production.

[0046] For example, such as Figure 3 As shown, the screening section 30 also includes a surrounding plate 35, which surrounds the outer periphery of the first conveyor 31 and the transparent plate to prevent the kernels from falling outside the first conveyor 31. The surrounding plate 35 has a discharge port 351 on the side near the transparent plate so that kernels that have not been found to be rotten can be sent to the array section 40 after inspection.

[0047] Furthermore, the enclosure 35 is provided with a mounting shaft 352, which extends along the width direction of the first conveyor 31. The feeding member 34 is movably mounted on the mounting shaft 352 so that it can move along the mounting shaft 352.

[0048] For example, such as Figure 3 As shown, the screening unit 30 also includes a guide member 36, which is detachably installed at the lower end of the distribution plate 23 and cooperates with and communicates with the discharge trough 231. The lower end of the guide member 36 has several openings arranged in at least one straight line and spaced apart. The size of the openings matches the size of the nuts to maintain a certain distance between the nuts arranged in a straight line. When the openings are arranged in two or more straight lines, the lines are parallel. The guide member 36 can be disassembled and reassembled according to the size and specifications of the nuts to change the opening diameter, making the operation more convenient than disassembling and reassembling the distribution plate 23.

[0049] When the material guide 36 is installed at the lower end of the material distribution plate 23, the material discharge trough 231 is configured as a rectangular straight trough, but it can also be configured as other shapes.

[0050] Furthermore, the guide component 36 is detachably installed at the lower end of the distribution plate 23 by means of screw connection.

[0051] In Option 1, when the material distribution plate 23 has only one straight material trough 231, that is, when the nuts on the first conveyor 31 are in a row, only one material feeding member 34 can be set, and the initial position of the material feeding member 34 is located on one side of a row of nuts. Correspondingly, only one collection member 33 can also be set.

[0052] In the second optional scheme, when the material distribution plate 23 has two straight material leakage grooves 231, that is, when there are two rows of nuts on the first conveyor 31, the material feeding member 34 is set to one or two, and the initial position of the material feeding member 34 is located in the middle of the two rows of nuts, and the corresponding collection member 33 is set to two.

[0053] To improve production efficiency, when the material distribution plate 23 has two or more straight material discharge troughs 231, that is, when there are two or more rows of nuts on the first conveyor 31, the screening unit 30 includes several of the aforementioned optional scheme one, or several of the aforementioned optional scheme two, or any combination of the aforementioned optional scheme one and optional scheme two.

[0054] Understandably, in actual production, by making the transparent plate sufficiently short along the length of the first conveyor 31, the inertia of the nuts during transport by the first conveyor 31 allows the nuts to move to the transparent plate. Alternatively, the transparent plate can be configured as a conveyor belt to provide power to the nuts and control their speed. Furthermore, the speed of the nuts at the transparent plate is less than the speed of the nuts at the first conveyor 31.

[0055] In an example scheme, such as Figure 1 As shown, the array unit 40 includes a second conveyor 41 and a third conveyor 42. The second conveyor 41 is located on one side of the screening unit 30, and the third conveyor 42 is located on one side of the second conveyor 41 along its length. The second conveyor 41 is used to receive the kernels after they have been detected by the screening unit 30 and to convey the kernels to the third conveyor 42. The third conveyor 42 can move up and down relative to the second conveyor 41. A sensor is provided at the junction of the third conveyor 42 and the second conveyor 41 to detect whether any kernels have been sent from the second conveyor 41 to the third conveyor 42. When a kernel is detected to have been sent to the third conveyor 42, the third conveyor 42 moves up and down relative to the second conveyor 41 once.

[0056] For example, the conveying speed of the third conveyor 42 is greater than the conveying speed of the second conveyor 41.

[0057] For example, the second conveyor 41 is a conveyor belt.

[0058] For example, the third conveyor 42 is a conveyor belt.

[0059] For example, the second conveyor 41 is at the same height as the first conveyor 31, enabling it to deliver nuts from the screening section 30 to the third conveyor 42. Furthermore, the second conveyor 41 has a perforated plate on its longitudinal side near the third conveyor 42, with the third conveyor 42 located below the perforated plate, allowing nuts from the second conveyor 41 to fall through the perforated plate to the third conveyor 42. By adjusting the specifications and dimensions of the perforated plate, an array of nuts can be achieved.

[0060] Furthermore, to ensure the efficiency of the kernel array, staff can be arranged on one side of the perforated plate to sort the kernels at the perforated plate.

[0061] For example, combined Figure 1 and Figure 4 The array section 40 also includes at least one material distribution channel 43, which is located between the screening section 30 and the second conveyor 41. The material distribution channel 43 includes a first hopper 431 and a second hopper 432. The first hopper 431 is installed on one side of the screening section 30, more specifically on one side of the material outlet 351 of the enclosure 35. After screening, the nuts can enter the first hopper 431 through the material outlet 351. The second hopper 432 is connected to the first hopper 431. One end of the second hopper 432 is engaged with the upper end of the second conveyor 41. The second hopper 432 can arrange the nuts from the first hopper 431 in a straight line and send them to the second conveyor 41.

[0062] Furthermore, the first hopper 431 is configured with a V-shaped channel structure.

[0063] Furthermore, the second hopper 432 is configured with a V-shaped channel structure.

[0064] Furthermore, the width of the second hopper 432 is smaller than the width of the first hopper 431.

[0065] Since the spacing between the nuts arranged in a straight line will be different after being screened by the screening section 30, the nuts are rearranged through the feeding and distribution channel 43 to ensure the efficiency of the arrangement between the nuts.

[0066] Understandably, to avoid nut accumulation at the second conveyor 41, the slopes of the first hopper 431 and the second hopper 432 should be configured to be sufficiently small.

[0067] In an example scheme, such as Figure 1 As shown, the gripping part 50 includes a plurality of vacuum adsorption heads 51 arranged in an array for adsorbing and gripping the nuts arranged on the third conveyor 42.

[0068] Understandably, a workbench is provided on one side of the array section 40 for placing the prepared chocolates to be added with nuts, and the gripping section 50 is able to move between the array section 40 and the workbench.

[0069] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
