Description

Technical Field

[0001] This invention relates to the field of lotus seed processing technology, and specifically to a device for removing the core from lotus seeds. Background Technology

[0002] The center of a lotus seed contains a green embryo, commonly known as the lotus heart. The lotus heart has an extremely bitter taste and is considered cold in nature. Although it has medicinal value, it affects the texture of the lotus seed. Therefore, it is usually removed when making lotus seed paste, sweet soup, eight-treasure porridge, and other similar foods. Currently, methods for removing the lotus heart include manual and automated methods. Manual methods involve using tools such as thin bamboo skewers, needles, and special core-removing pliers, but this is inefficient. Automated methods use air-filled or water-flushing core-removing machines, but these are more complex and have higher operating costs. Summary of the Invention

[0043] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art. It should be noted that the description of these embodiments is for the purpose of aiding understanding the present invention, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0044] Reference Figures 1 to 12 As shown, this embodiment provides a lotus seed core removal device, including a conveying mechanism 1, a defective product rejection mechanism 2, a rotating mechanism 3, a feeding mechanism 4, a turntable mechanism 5, a straightening mechanism 6, a core-punching mechanism 7, and a discharge port 8. The defective product rejection mechanism 2 includes a camera 21 and a rejection component 22. The camera 21 is located to the left of the rejection component 22. The lotus seeds are conveyed from left to right and finally discharged from the discharge port 8. In this embodiment, the "up, down, left, right" directions are... Figure 5 The up, down, left, and right directions shown on the paper are based on the reference.

[0045] Furthermore, combined Figure 5 and Figure 7As shown, the feeding mechanism 4 includes a feeding hopper 41, a stirring element 42 located at the bottom of the feeding hopper 41, and a driving assembly 43 for moving the stirring element 42. The function of the stirring element 42 is to stir the lotus seeds evenly for easy discharge. The driving assembly 43 includes a first rotating shaft 431, a rotating element 432, and a actuating element 433. The rotating element 432 is located on the first rotating shaft 431. During the rotation of the rotating element 432, one end of the actuating element 433 intermittently contacts the rotating element 432, and the other end is connected to the stirring element 42 through a threaded rod 434. Specifically, the rotating component 432 is shaped like a five-pointed star, with multiple protrusions 4321 and multiple grooves 4322. There is a groove 4322 between two adjacent protrusions 4321. The agitator 433 has a contact portion 4331, which moves back and forth between the multiple protrusions 4321 and grooves 4322. During the movement, the contact portion 4331 drives the agitator 433 to swing up and down. When the agitator 433 swings, it drives the stirring component 42 to move to stir the lotus seeds evenly.

[0046] Reference Figures 1 to 4 As shown, there is a turntable mechanism 5 between the feeding mechanism 4 and the conveying mechanism 1. The turntable mechanism 5 includes a turntable 51, and the turntable 51 is provided with multiple discharge ports 511. The size of the discharge port 511 is slightly larger than that of a lotus seed, so as to ensure that two whole lotus seeds will not enter the discharge port at the same time. Furthermore, the turntable mechanism 5 also includes a brush 54, an anti-clogging component 52 wound around the turntable 51, and a fixing member 53 cooperating with the anti-clogging component 52. The brush 54 rotates around its own axis, and the brush 54 can further prevent the lotus seeds from clogging during the rotation process. The number and position of the anti-clogging component 52 and the discharge port 511 are corresponding. Specifically, in this embodiment, there are three anti-clogging components 52 and three discharge ports 511. The fixing member 53 and the above-mentioned actuating member 433 are connected by a first spring (not shown in the figure). More specifically, the fixing member 53 is provided with a first connecting hole 532, and the actuating member 433 is provided with a second connecting hole 4332. One end of the first spring passes through the first connecting hole 532, and the other end passes through the second connecting hole 4332.

[0047] Furthermore, the anti-clogging component 52 includes a first bracket 521 and a second bracket 522. The first bracket 521 is rotatably connected to the second bracket 522 via a first pin 56. A second spring 523 is provided between the first bracket 521 and the second bracket 522. One end of the first bracket 521 has an abutment portion 5212 that can abut against the fixing member 53, and the other end has a first push rod 5211 that extends into the discharge port 511. There is one fixing member 53. The turntable 51 rotates counterclockwise. During the rotation, each anti-clogging component 52 will collide with the fixing member 53. Specifically, the abutment portion 5212 will contact the connecting shaft 531 on the fixing member 53. The connecting shaft 531 provides a rightward push force to the first bracket 521, and the first push rod 5211 on the first bracket 521 provides a leftward push force to the lotus seeds in the discharge port 511, preventing larger or rotten lotus seeds from getting stuck in the discharge port 511. The turntable mechanism 5 is also equipped with a curved steel plate 55, which can prevent lotus seeds from falling off the side.

[0048] Furthermore, the conveying mechanism 1 is used to convey lotus seeds. The conveying mechanism 1 has a conveying chain 11 and multiple third rollers 12 arranged on the conveying chain 11. The conveying chain 11 drives the multiple third rollers 12 to move linearly from left to right to convey lotus seeds. Adjacent rollers 12 are spaced apart, and a lotus seed is placed between two adjacent third rollers 12. Furthermore, there are two straightening mechanisms 6, located between the turntable mechanism 5 and the camera 21 of the defective product rejection mechanism 2, and between the rotating mechanism 3 and the core-punching mechanism 7, respectively. That is, the lotus seeds are straightened before the camera 21 takes pictures and before the core is punched. Even further, combined with... Figure 5 As shown, the straightening mechanism 6 includes a synchronous wheel assembly 61, which includes two rollers 611 arranged opposite each other and a conveyor belt 612 wound between the two rollers 611. Multiple third rollers 12 are located on the conveyor belt 612. When the conveyor belt 612 is running, it drives the multiple third rollers 12 to rotate. Two adjacent third rollers 12 straighten and level the lotus seeds that are tilted or standing upright, which facilitates the subsequent identification of the direction of the lotus seeds and the core-opening processing.

[0049] Combination Figure 5 and Figure 6As shown, the rejection assembly 22 includes a third motor 221 and a rejection component 222 rotatably connected to the output shaft of the third motor 221. The diameter of the front end of the rejection component 222 is smaller than the diameter of the rear end, resulting in a simple structure and low operating cost. The function of the rejection component 222 is to reject defective lotus seeds captured by the camera 21. The rejection component 222 is cone-shaped, allowing for better contact with the lotus seeds and avoiding interference with the third roller 12. Opposite the rejection component 22 is a receiving cavity 23, which contains an inclined plate that slopes downwards. Defective lotus seeds are rejected into the receiving cavity 23 and fall onto the inclined plate, accumulating from the bottom of the inclined plate.

[0050] The rotating mechanism 3 is used to grip the lotus seeds and rotate the reversed lotus seeds 180 degrees. Further, refer to... Figure 8 As shown, the rotating mechanism 3 includes a linkage assembly 31, a slider 32, a first motor 33, a second motor 34, a gripper 342, a connector 343, and a slide rail 39. The first motor 33 and the second motor 34 share a motor mounting base 38, which is fixedly connected to the slider 32. The slider 32 moves up and down along the length of the slide rail 39, thus allowing the first motor 33 and the second motor 34 to move together with the slider 32 in the vertical direction. Further, the linkage assembly 31 drives the slider 32 to move vertically. Specifically, the linkage assembly 31 includes a first cam 311, a first pull rod 312, a first rocker arm 313, and a connecting block 314 connected to the first rocker arm 313. The connecting block 314 is fixedly connected to the slider 32. More specifically, one end of the first pull rod 312 is fixedly connected to the first rocker arm 313, and the other end is connected to the first cam 311 via a first roller 35. During rotation, the first cam 311 drives the first pull rod 312 to reciprocate linearly. The first swing arm 313 swings or rotates. One end of the first swing arm 313 is provided with a bearing 36 and a roller assembly fixedly connected to the bearing 36. The roller assembly includes two second rollers 37, which are arranged vertically. A connecting block 314 is located between the two second rollers 37. During the rotation of the first swing arm 313, the two vertically arranged second rollers 37 drive the connecting block 314 to move back and forth in the vertical direction, thereby driving the slider 32 to move back and forth in the vertical direction, and finally causing the gripper 342 to move in the vertical direction. When it is necessary to pick up lotus seeds, the gripper 342 moves downward; after picking up the seeds, the gripper 342 moves upward.

[0051] Furthermore, the gripper 342 is used to grip or release lotus seeds. The gripper 342 is mounted on the second motor 34. There are two grippers 342, and they are arranged opposite each other. The second motor 34 drives the two grippers 342 to move closer or further apart. When the two grippers 342 move closer, they grip the lotus seeds; when they move further apart, they release the lotus seeds. More specifically, the connecting member 343 is provided with a guide groove 3431, and the gripper 342 moves along the guide groove 3431. Furthermore, the first motor 33 is equipped with a driving wheel 331, and the second motor 34 is equipped with a driven wheel 341. The driving wheel 331 and the driven wheel 341 are connected by a synchronous belt (not shown in the figure). That is, the first motor 33 can drive the driving wheel 331 to rotate, and the driving wheel 331 drives the driven wheel 341 to rotate. The driven wheel 341 is fixedly connected to the connecting member 343. Therefore, during the rotation of the driven wheel 341, it drives the gripper 342 to rotate, specifically driving the gripper 342 to rotate 180 degrees. Therefore, in this embodiment, the linkage assembly 31 drives the gripper 342 to move up and down, and the first motor 33 and the second motor 34 drive the gripper 342 to rotate. The second motor 34 drives the gripper 342 to grasp or release the lotus seeds, completing the entire reversal of the lotus seed. The structure is simple and compact.

[0052] Reference Figure 10 and Figure 11 As shown, the core-punching mechanism 7 is used to core the lotus seeds on the conveying mechanism 1. Further, the core-punching mechanism 7 includes a second cam 71, a second push rod 72, and a hollow needle 73 fixed on the second push rod 72. The second cam 71 is connected to the second push rod 72 via a fourth roller 77. The second push rod 72 is provided with a water inlet 721, which communicates with the hollow needle 73. The second push rod is provided with a fourth spring 78 and a stop block that cooperates with the fourth spring 78. During use, the second cam 71 drives the second push rod 72 to reciprocate linearly. The compressed fourth spring 78, through its elastic restoring force, ensures that the fourth roller 77 always elastically presses against the second cam 71, guaranteeing that the second push rod 72 and the second cam 71 move synchronously. The structure is simple, stable, reliable, and easy to operate. Specifically, the hollow needle 73 is thin and roughly needle-shaped. The second push rod 72 has a channel that communicates with the hollow needle 73 and the water inlet 721. More specifically, the second push rod 72 includes a connector 79, and the water inlet 721 is connected to the connector 79. The hollow needle 73 is connected to the body of the second push rod 72 through the connector 79.

[0053] The punching mechanism 7 also includes a third cam 75. The third cam 75, the second cam 71, and the first cam 311 are located on the same rotating shaft, making the device structure more compact and requiring less space. The third cam 75 cooperates with a water valve 76 to realize water discharge from the hollow needle 73. The water valve 76 is connected to a corresponding water pump device. Further, the water valve 76 has an inlet 764 and an outlet 765. The inlet 764 is connected to the water pump device, and the outlet 765 is connected to the water inlet 721. Specifically, the water pump device provides water, which enters the inlet 764. When water is needed, the water flows from the inlet 764 to the outlet 764 and the water inlet 721 in sequence, and finally flows out from the hollow needle 73. More specifically, the water valve 76 has a screw 763, a third spring 763 sleeved on the screw 763, and a steel ball disposed on the third spring 763. When the protrusion of the third cam 75 rotates to directly below the screw 763, it pushes the screw 763 upward, and the screw 763 drives the steel ball 761 to rise to a position where... Figure 11 As shown, water from the inlet 764 flows out from both sides of the steel ball 761 and finally flows out from the outlet 765, thus achieving water output from the hollow needle 73. When the protrusion of the third cam 75 moves away (external force is withdrawn), the water entering from the inlet 764 will press down on the steel ball 761, causing the steel ball 761 to fall on a limiting surface 766, preventing water from flowing out.

[0054] In use, the second cam 71 drives the second push rod 72 to move back and forth linearly, so that the hollow needle 73 performs core-opening processing on the lotus seeds located on the conveyor chain 11. As the hollow needle 73 opens the lotus heart, water in the water valve 76 enters the water inlet 721 from the outlet 765 to supply liquid to the hollow needle 73. The pressurized liquid flow flushes the lotus heart out of the hollow needle 73.

[0055] Furthermore, combined Figure 9As shown, the punching mechanism 7 also includes a pressure roller mechanism 74 located in front of the hollow needle 73. The pressure roller mechanism 74 includes a first pressure roller 741, a second pressure roller 742, an elastic element 743, a first mounting plate 745, a second mounting plate 746, a third mounting plate 747, and a fourth mounting plate 748. The first pressure roller 741 and the second pressure roller 742 are arranged in parallel and located between the first mounting plate 745 and the second mounting plate 746. Specifically, the first pressure roller 741 and the second pressure roller 742 are connected between the first mounting plate 745 and the second mounting plate 746 by a second pin (not shown in the figure). A screw is provided above the first pressure roller 741 or the second pressure roller 742. The column and the elastic element 743 sleeved on the stud are located between the third mounting plate 747 and the fourth mounting plate 748. The first pressure roller 741 and the two adjacent second rollers 37, and the second pressure roller 742 and the two adjacent second rollers 37 form a three-axis centering structure. In order to accurately position the lotus seed on the left-side three-axis centering structure, the center of the lotus seed is aligned with the hollow needle. When transported to the right-side three-axis centering structure, the hollow needle can be inserted exactly into the center of the lotus seed (the hollow needle is located directly behind the right-side three-axis centering mechanism) without any misalignment. That is, the core punching in this embodiment is more accurate. Furthermore, when the lotus seed passes through the first pressure roller 741 or the second pressure roller 742, the first mounting plate 745, the second mounting plate 746, and the intermediate plate 744 between the first mounting plate 745 and the second mounting plate 746 move upward as a whole, and the elastic element 743 is compressed.

[0056] In this embodiment, the conveying mechanism 1, defective product rejection mechanism 2, rotating mechanism 3, feeding mechanism 4, turntable mechanism 5, aligning mechanism 6, punching mechanism 7, and discharge port 8 are arranged in pairs on both sides of the device to improve work efficiency. (Refer to...) Figure 12 As shown, the rotation of each mechanism in this embodiment is driven by multiple rotating shafts 9, a conveyor belt 91, and gears 92. The gears 92 are mounted on the rotating shafts 9, and the conveyor belt 91 is wound between the multiple gears 92. The design is relatively compact and ingenious, and the overall size of the device is small.

[0057] In this embodiment, the lotus seed core removal device feeds the lotus seeds to be processed from the feed hopper 41 onto the conveyor chain 11. The alignment mechanism 6 first vibrates and aligns the conveyed lotus seeds. Then, the camera 21 detects and identifies the lotus seeds conveyed on the conveyor chain 11, quickly and accurately determining the direction of the lotus seeds and identifying whether the lotus seeds have defects such as incomplete shelling, incomplete peeling, or damage. Based on the detection results, the rejection component 22 removes the defective lotus seeds from the conveyor chain 11. The removed defective lotus seeds are collected through the collection cavity 23 for further processing. Then, the rotating mechanism 3 rotates the top of the conveyor chain 11... The incorrect lotus seeds are turned around, for example, by rotating them 180° and placing them back on the conveyor chain 11. Then, the straightening mechanism 6 vibrates and straightens the conveyed lotus seeds. The first three-axis centering structure then repositions the lotus seeds to ensure that the center of the lotus seed is directly in front of the hollow needle. When the lotus seeds reach the second three-axis centering structure, the core-punching mechanism 7 sequentially performs core-punching processing on the pressed and fixed lotus seeds. Finally, the conveyor chain 11 transports the core-punched lotus seeds to the discharge port 8, thereby realizing the automatic core-punching processing of lotus seeds. The structure of the device is relatively simple and compact, and the manufacturing cost is low.
