Description

Technical Field

[0001] This utility model relates to the field of nut processing technology, and in particular to a nut opening machine. Background Technology

[0002] Nut-opening machines play a crucial role in the nut-opening process, particularly for nuts like chestnuts and hazelnuts. During roasting and baking, the high temperatures cause rapid internal expansion, making the shells prone to exploding, posing a danger and causing burns. Therefore, a slit needs to be made before heating to prevent explosions. Traditional manual nut-opening is time-consuming, laborious, and inefficient; the hard, smooth shells also pose a risk of cuts. Using existing machines offers better operational safety and higher efficiency. Since most nuts are semi-circular, existing nut-opening machines open randomly, wherever the blade touches the nut. This results in inconsistent opening positions, reducing the aesthetic appeal of the nuts, affecting product quality consistency, hindering seasoning penetration, leading to inconsistent flavor, and causing inconvenience in subsequent cooking and eating. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned shortcomings by providing a nut-opening machine that makes the opening position of semi-circular nuts more uniform.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a nut-opening machine, comprising a machine body, wherein the following are sequentially arranged on the machine body:

[0005] The feeding assembly, located on one side of the machine body, is used to transport the nuts to be opened toward its output end;

[0006] The transport and tilting assembly includes a first conveyor belt and a second conveyor belt that are distributed at the same height and have the same conveying direction. A lifting plate is provided between the first conveyor belt and the second conveyor belt that can slide up and down.

[0007] The first power unit is used to drive the transport tilting assembly to move;

[0008] The input end of the first conveyor belt faces the output end of the feeding component. The feeding component can transport nuts onto the first conveyor belt. The width of the lifting plate is smaller than the width of the nuts. The height of the lifting plate is lower than that of the first and second conveyor belts. It can transport nuts with the flat surface facing down and the arc surface facing up. It is also used to pause the nuts with the arc surface facing down when they pass by. In conjunction with the first conveyor belt, it can push the nuts that are paused and have the arc surface facing down to flip over and be transported onto the second conveyor belt.

[0009] A clamping opening assembly is located on the side of the machine body away from the feeding assembly, and is used to clamp and open nuts with the arc surface facing upward;

[0010] The second power unit is used to drive the clamping opening assembly to move.

[0011] A guide assembly, disposed between the second conveyor belt and the clamping opening assembly, is used to guide the nut with its arc-shaped surface facing upwards to the input end of the clamping opening assembly.

[0012] Furthermore, both the first and second conveyor belts include two rollers and a belt that is driven on the corresponding rollers. The first power unit can cooperate with one of the first belts to drive the corresponding roller in the second conveyor belt to rotate. The roller is also driven by a gearbox that drives the corresponding roller in the second conveyor belt to rotate. The corresponding roller of the first conveyor belt is driven by another first belt that cooperates with the feeding assembly.

[0013] Furthermore, the machine body is equipped with a cylinder and an image recognition component. The cylinder is used to drive the lifting plate to move up and down, and the image recognition component is used to identify the size of the nuts.

[0014] Furthermore, the clamping opening assembly includes a first clamping component and a second clamping component that are vertically distributed and rotatably disposed on the machine body. A compression spring is provided on the inner wall of the machine body. Each of the compression springs is used to squeeze the first clamping component and the second clamping component, causing them to rotate toward each other and clamp the nut to open it.

[0015] Furthermore, the first clamping component includes a first frame rotatably mounted on the machine body, and the second clamping component includes a second frame rotatably mounted on the machine body and distributed vertically above the first frame, and both the first and second frames are provided with:

[0016] Multiple rollers are rotatably mounted on the first and second frames;

[0017] A drive belt is rotatably mounted on each roller, and there are two drive belts on both the first and second frames, with a gap between the two drive belts. The two drive belts can transport nuts at the gap. A rotatable blade is provided at the gap between the two drive belts on the first frame. A second belt is provided between the blade shaft and the corresponding roller. When the blade moves, it can open the arc surface of the nut at the gap.

[0018] Two meshing gears are coaxially mounted on the corresponding rollers of the first and second frames, respectively.

[0019] Furthermore, the second power unit includes a drive motor, and the moving end of the drive motor is equipped with a third belt. When the drive motor is working, it can work with the third belt to drive the rollers on the second frame that are coaxially engaged with the gears to rotate.

[0020] Furthermore, the guide assembly includes an outer baffle and an inner guide plate that is distributed in a funnel shape and can be elastically oscillating on the inner wall of the outer baffle.

[0021] The beneficial effects of this utility model are reflected in:

[0022] In this invention, nuts are conveyed to the first conveyor belt via a feeding assembly. At this time, the first power unit causes the transport flipping assembly to move, and the first conveyor belt conveys the nuts to the second conveyor belt. When passing the lifting plate, the flat-faced nuts will pass through the lifting plate and the second conveyor belt in sequence, while the arc-faced nuts will stop at the lifting plate, which has a height difference between the first and second conveyor belts. As the first conveyor belt continues to work, the flat-faced nuts will continue to move until they come into contact with the arc-faced nuts that are stopped, and push them to flip over, so that the arc-faced nuts are flipped to face down. This ensures that the subsequent openings are all on their arc surfaces, making the semi-circular openings of the nuts more uniform, thus ensuring that the openings are beautiful and neat, and facilitating subsequent processing such as roasting, peeling, and seasoning.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0033] Please see Figure 1-7 This utility model discloses a nut opening machine, including a machine body 1. The machine body 1 is sequentially provided with a feeding component 2, a transport and flipping component 3, a first power unit 4, a guiding component 5, a clamping and opening component 6, and a second power unit 7. The machine body 1 includes a housing 11, and a feeding port 12 is opened on one side of the housing 11. The feeding component 2 is set at the corresponding feeding port 12 of the housing 11. In use, the operator places the nuts to be opened at the feeding component 2, and the feeding component 2 will transport the nuts to be opened towards its output end.

[0034] In one embodiment, the transport and flipping assembly 3 includes a first conveyor belt 31 and a second conveyor belt 32 that are distributed at the same height and have the same conveying direction. A lifting plate 33 is slidably disposed between the first conveyor belt 31 and the second conveyor belt 32. A first power unit 4 is mounted on the machine body 1 and is used to drive the transport and flipping assembly 3 to move. The input end of the first conveyor belt 31 faces the output end of the feeding assembly 2. The feeding assembly 2 can transport nuts to the first conveyor belt 31. The width of the lifting plate 33 is smaller than the width of the nuts. The height of the lifting plate 33 is lower than that of the first conveyor belt 31 and the second conveyor belt 32. It can transport nuts with the flat surface facing down and the arc surface facing up. It is also used to pause the nuts with the arc surface facing down when they pass by. In conjunction with the first conveyor belt 31, it can push the nuts that are paused and have the arc surface facing down to flip and transport them to the second conveyor belt 32.

[0035] Meanwhile, the clamping opening assembly 6 is located on the side of the machine body 1 away from the feeding assembly 2, and is used to clamp and open the nuts with the arc surface facing upward. The second power unit 7 is used to drive the clamping opening assembly 6 to move. The guide assembly 5 is located between the second conveyor belt 32 and the clamping opening assembly 6, and is used to guide the nuts with the arc surface facing upward to the input end of the clamping opening assembly 6.

[0036] In practice, nuts are conveyed to the first conveyor belt 31 by the feeding component 2. At this time, the first power unit 4 causes the transport flipping component 3 to move. The first conveyor belt 31 will convey the nuts to the second conveyor belt 32. When passing the lifting plate 33, the flat-faced nuts will pass through the lifting plate 33 and the second conveyor belt 32 in sequence, while the arc-faced nuts will stay at the lifting plate 33, which has a height difference between the first conveyor belt 31 and the second conveyor belt 32. As the first conveyor belt 31 continues to work, the flat-faced nuts will continue to move to contact the arc-faced nuts that are staying, and push them to flip over, so that the arc-faced nuts are flipped to face down, and then move to the second conveyor belt 32.

[0037] With this design, the nuts with their flat surfaces facing down are guided by the guide component 5 to the input end of the clamping and opening component 6. When working, the clamping and opening component 6 will effectively clamp and position the nut so that the arc surface can be opened stably and accurately. After the opening is completed, the nut falls out from the output end of the clamping and opening component 6, thus completing the opening operation. This device can make the opening position of the semi-circular nuts tend to be uniform, thus ensuring that the opening is beautiful and neat, and at the same time facilitating subsequent processing such as roasting, peeling and seasoning.

[0038] In one embodiment, both the first conveyor belt 31 and the second conveyor belt 32 include two rollers and belts that are driven on the corresponding rollers. The moving end of the first power unit 4 is driven by a first belt 35, which can work with the first belt 35 to drive the corresponding rollers in the second conveyor belt 32 to rotate. The roller is also driven by a gearbox 34 that drives the corresponding rollers in the second conveyor belt 32 to rotate. Another first belt 35 that works with the feeding assembly 2 is driven on the corresponding roller of the first conveyor belt 31.

[0039] In specific implementation, the first power unit 4 can be an electric motor, and the feeding component 2 can be a plate conveyor. After it starts, it will work with the first belt 35 to drive the first conveyor belt 31. The first conveyor belt 31, together with another first belt 35, will cause the feeding component 2 to lift the nuts onto the first conveyor belt 31. When the first belt 35 is working, it will work with the gearbox 34 to make the second conveyor belt 32 move at a faster speed than the first conveyor belt 31. During this process, the number of nuts on the first conveyor belt 31 will be more than the number of nuts on the second conveyor belt 32. This can effectively push the nuts with the arc surface facing down at the lifting plate 33 to flip over. Finally, the nuts with the flat surface facing down will be quickly conveyed to the clamping opening component 6 by the second conveyor belt 32. This structure uses one power source to drive three conveying devices at the same time, which saves costs while ensuring the flipping effect, making it convenient for practical use.

[0040] In addition, the feeding component 2 mentioned above is common knowledge in the field, so its specific structure and working principle will not be described in detail here.

[0041] In one embodiment, a vertically arranged cylinder and an image recognition component (not shown in the figure) are installed on the body 1. The cylinder is used to drive the lifting plate 33 to move up and down, and the image recognition component is used to identify the size of the nuts.

[0042] In practice, since the nuts vary in size, the image recognition component can identify the size of the nuts at the lifting plate 33. When the nuts are small, the cylinder drives the lifting plate 33 to move upward to shorten the height difference with the first conveyor belt 31 and the second conveyor belt 32, preventing the small nuts from getting stuck between the first conveyor belt 31 and the second conveyor belt 32, while also ensuring that they have the corresponding flipping effect. When the nuts are large, the cylinder drives the lifting plate 33 to move downward to increase the height difference with the first conveyor belt 31 and the second conveyor belt 32, thereby adapting to this type of nut and ensuring that it can still be flipped, thus improving the flipping accuracy and ensuring the flipping effect. The cylinder and the image recognition component are common knowledge in the field, so their specific structural composition and working principle will not be described in detail in this article.

[0043] In one embodiment, the clamping opening assembly 6 includes a first clamping component and a second clamping component that are vertically distributed and rotatably mounted on the body 1, and a compression spring 68 is provided on the inner wall of the body 1.

[0044] In practice, each compression spring 68 is used to squeeze the first clamping component and the second clamping component, causing them to rotate toward each other and clamp the nut. After the nut is fixed, the opening is made, which ensures the accuracy of the opening.

[0045] In one embodiment, the first clamping component includes a first frame 61 rotatably mounted on the machine body 1, and the second clamping component includes a second frame 62 rotatably mounted on the machine body 1 and distributed vertically to the first frame 61. Both the first frame 61 and the second frame 62 are provided with: a plurality of rollers 64 rotatably mounted on the first frame 61 and the second frame 62; and a drive belt 65 rotatably mounted on each roller 64. The drive belts 65 on both the first frame 61 and the second frame 62 are... There are two transmission belts 65, and there is a gap between the two corresponding transmission belts 65. The two corresponding transmission belts 65 can transport nuts at the gap. A rotatable blade 66 is installed at the gap between the two transmission belts 65 on the first frame 61. A second belt 67 is provided between the shaft of the blade 66 and the corresponding roller 64. When the blade 66 moves, it can open the arc surface of the nut at the gap. Gears 63 are coaxially installed at the corresponding rollers 64 of the first frame 61 and the second frame 62, and the two gears 63 mesh with each other.

[0046] In practice, the flat-down nuts are conveyed by the second conveyor belt 32 to the space between the first and second clamping components. At this time, the second power unit 7 is activated to rotate the corresponding rollers 64 on the first and second clamping components. The transmission belt 65 moves with the rotation of the rollers 64, thereby driving the nuts to move closer to the blade 66. Since there is a gap between the two transmission belts 65 on the first frame 61 and the second frame 62, the nuts are in contact with the transmission belts 65 and exist in the gap. Therefore, it can be ensured that the nuts are aligned with the blade 66 while being conveyed. When the corresponding rollers 64 move, they work with the second belt 67 to drive the blade 66 to rotate, thereby opening the nuts that have moved to the bottom. The opening is located on the arc surface of the nuts. After the opening is completed, the transmission belt 65 continues to work to output the nuts.

[0047] In addition, due to the different sizes of nuts, when they move to the bottom of the blade 66, they will push the blade 66 upward, thereby causing the first frame 61 to rotate upward around the connection point with the body 1, thus enabling adaptation. The setting of the compression spring 68 also ensures that the blade 66 is not completely pushed open, and it provides corresponding thrust to the first frame 61 and the second frame 62. This method ensures that the blade 66 can open along the corresponding arc of the nut's curved surface, rather than making a hard opening. The aforementioned hard opening will cause the nuts to break and the depth of the opening to be uneven, while this method of opening can effectively ensure the integrity of the nut kernel, thus facilitating actual use.

[0048] In one embodiment, the second power unit 7 includes a drive motor 71 mounted on the body 1. The moving end of the drive motor 71 is provided with a third belt 72. The side of the third belt 72 away from the drive motor 71 is in transmission engagement with a roller 64 on the second frame 62 that is coaxially engaged with a gear 63.

[0049] With this design, when the drive motor 71 is working, it can work with the third belt 72 to drive the roller 64 on the second frame 62, which is coaxially engaged with the gear 63, to rotate. The gear 63 will drive another gear 63 to rotate, thereby causing the transmission belt 65 on the first frame 61 and the second frame 62 to move, and at the same time, it will drive the blade 66 to rotate.

[0050] In one embodiment, the guide assembly 5 includes an outer baffle 51 mounted on the body 1 and an inner guide plate 52 that is funnel-shaped and elastically swingable and mounted on the inner wall of the outer baffle 51.

[0051] With this design, when the nuts are transported face down onto the second conveyor belt 32, they will be guided by the inner guide plate 52 and move towards the gap between the two transmission belts 65. Since the nuts being transported are of different sizes, the elastically swinging inner guide plate 52 can be adjusted to ensure that it has a good guiding effect.

[0052] In addition, the number of the above-mentioned feeding component 2, transport and flipping component 3, guiding component 5, clamping opening component 6 and second power unit 7 can be multiple, thereby forming multiple workstations for processing nuts. This method can increase processing efficiency without changing the number of power sources.
