Abstract
Description
Technical Field
[0001] This invention relates to the field of pine nut processing, specifically to an adjustable intelligent conveying mechanism and method for a pine nut opening machine. Background Technology
[0002] Pine nuts, also known as pine nuts, are the seeds of plants such as Korean pine in the Pinaceae family. They are one of the most common nuts, rich in fat, protein, carbohydrates, etc. They are an important traditional Chinese medicine and also have high nutritional value.
[0003] Since pine nuts are sealed after being removed from the pine cone, they are not convenient to eat. As pine nuts are a type of nut food, unlike sunflower seeds, their shells are relatively thick. To make them easier to eat, manufacturers usually open them up. There are two widely used methods: one is frying, and the other is heating and then cooling to open them up through thermal expansion and contraction. For example, a fully automatic pine nut opening and conveying device has been disclosed, announcement number: CN112790398A.
[0004] Both of these methods will have a certain impact on the kernels of pine nuts, affecting their texture and taste. Currently, some high-quality pine nuts are made by physically squeezing them to open them, in order to ensure their texture and taste. However, current conveying equipment does not have a device to limit the movement of the pine nuts so that they can be conveyed in a specified posture to facilitate the opening of the opening device. For example, the patent mentioned above does not restrict the posture of the pine nuts during the conveying process, which means that the pusher block cannot squeeze the pine nuts when it moves, and may cause jamming.
[0005] This patent uses extrusion blocks to extrude pine nuts, with the extrusion blocks positioned at four locations: three o'clock, nine o'clock, six o'clock, and twelve o'clock. However, since the pine nuts are not restrained, they may also be positioned at eleven o'clock or five o'clock. In this position, the extrusion operation will inevitably be unforced, which obviously needs to be improved.
[0006] Secondly, the patent does not provide a solution on how to release the release molecule into the storage tube. Summary of the Invention

[0024] An incomplete gear is rotatably installed between the two baffles, and a second rack plate is fixed on one side of each of the two baffles. The second rack plate cooperates with one of the second rack plates or the other second rack plate.
[0025] A second motor is fixed to the bottom of the receiving plate, and the output shaft of the second motor passes through the receiving plate and is coaxially fixed with the incomplete gear.
[0026] As a further embodiment of the present invention: one end of the guide tube is further provided with a horizontally arranged conveying component, which is connected to the guide tube;
[0027] The top of the feed pipe is equipped with a protective plate, while the conveying parts are exposed.
[0028] The conveying component has a feeding plate at the end away from the guide pipe, and the opening mechanism is installed on the feeding plate portion;
[0029] The conveyor is V-shaped with an angle of 60° between its two sides.
[0030] As a further embodiment of the present invention: the opening mechanism includes a support plate fixed to the bottom of the conveying component, and a limiting component is installed on the support plate at the end of the conveying component;
[0031] The support plate is also fixed with a plurality of first guide rods. A receiving seat is slidably installed on the first guide rod. An opening clamp is installed opposite to the receiving seat. The opening clamp is slidably connected to the receiving seat through a sliding groove.

[0062] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0063] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.
[0064] Example 1, please refer to Figures 1 to 12 An adjustable intelligent conveying mechanism for a pine nut opening machine includes a conveying bracket 1 and protective covers 101 installed on both sides of the conveying bracket 1. It also includes a conveying mechanism installed on the conveying bracket 1, which conveys pine nuts in a specified posture.
[0065] A single feeding assembly is installed inside the conveying bracket 1 and cooperates with the conveying mechanism to convey pine nuts one by one in a specified posture.
[0066] An opening mechanism is installed on one side of the conveying bracket 1 and cooperates with the single feeding assembly. The opening mechanism opens and discharges the pine nuts conveyed by the single feeding assembly.
[0067] In this embodiment of the invention, pine nuts are positioned and conveyed into a single feeding assembly by a conveying mechanism, and the posture of the pine nuts changes from random to specified during this process.
[0068] Pine nuts in the single feeding assembly are fed one by one to the opening mechanism, which opens the pine nuts and then discharges them to a designated location.
[0069] The conveying mechanism includes two conveying rollers 6 rotatably mounted on the conveying bracket 1, and the two conveying rollers 6 are connected by a conveyor belt 601.
[0070] The conveyor belt 601 has multiple openings at equal intervals along the conveying direction, and multiple positioning members 602 are fixed at equal intervals along the conveying direction on the conveyor belt 601. Each positioning member 602 is provided with a conveying port, and the conveying port and the opening are concentrically arranged with the conveying port of the positioning member 602.
[0071] The passage and the conveying port of the positioning member 602 are both elliptical in shape;
[0072] A motor 2 is fixed on one side of the conveying bracket 1, and the output shaft of the motor 2 is coaxially fixed with the rotating shaft of one of the conveying rollers 6.
[0073] In this embodiment of the invention, when the No. 1 motor 2 is working, it drives one of the conveyor rollers 6 to rotate through its conveyor shaft. When one of the conveyor rollers 6 rotates, it drives the other conveyor roller 6 to rotate by driving the conveyor belt 601 to rotate. In this way, the two conveyor rollers 6 rotate synchronously and in the same direction to convey the conveyor belt 601. The conveying of the conveyor belt 601 drives the positioning member 602 to rotate.
[0074] It should be noted that the first motor 2 in this embodiment is a servo motor. Of course, a stepper motor or DC motor can also be selected according to actual production needs, as long as the driving requirements are met. This invention does not impose any specific limitations.
[0075] The conveying support 1 is provided with a storage box 3, and the storage box 3 is fixed to the conveying support 1 by support arms 301 fixed on both sides;
[0076] The bottom of the storage box 3 is provided with multiple discharge holes 303 that cooperate with the positioning member 602, and both sides of the multiple discharge holes 303 are provided with arc-shaped surfaces 304 for limiting the shape of pine nuts. The discharge holes 303 have the same shape as the conveying port of the positioning member 602.
[0077] The storage bin 3 is provided with an inclined surface 302.
[0078] In this embodiment, the pine nuts that need to be opened are poured into the storage box 3, and the inclined surface 302 can drive the pine nuts to slide towards the discharge hole 303.
[0079] The pine nuts in the storage box 3 will be limited by the arc surface 304, so that the edge of the pine nuts will move towards the discharge hole 303, so that the edge of the pine nuts will be facing down when they fall through the discharge hole 303. When the pine nuts fall through the discharge hole 303, they will move into the conveying port of the positioning member 602, and the pine nuts will be carried by the conveying of the positioning member 602.
[0080] Since the pine nuts are thinner than wide and have an elliptical shape, they are tilted under the constraint of the arc surface 304. The elliptical shape of the feeding hole 303 and the positioning member 602 limit the feeding port, so that the pine nuts can enter the feeding hole 303 and the positioning member 602 in a specified state.
[0081] It should also be noted that a stirring structure can be installed inside the storage tank 3 to prevent the accumulation of pine nuts from reducing their movement energy. Since the implementation of the stirring structure is relatively simple, the present invention does not specifically limit the stirring structure used.
[0082] A limiting plate 7 is fixed inside the conveying bracket 1. The limiting plate 7 is located inside the conveyor belt 601 and is in clearance fit with the conveyor belt 601. A conveying cylinder 701 is fixed at the end of the limiting plate 7. The conveying cylinder 701 is in cooperation with the conveying port of the positioning member 602 and the through port of the conveyor belt 601. The conveying cylinder 701 is also in cooperation with the single unloading assembly.
[0083] In this embodiment of the invention, when the pine nuts are in the conveying port of the positioning member 602, the positioning member 602 and the pine nuts are driven to move toward the conveying cylinder 701 by the conveying of the conveyor belt 601.
[0084] When the pine nuts reach the position of the conveying cylinder 701, the pine nuts are limited by the limiting plate 7 to prevent them from falling during the conveying process. When the conveying port of the conveyor belt 601 and the conveying port of the positioning member 602 move to be concentric with the conveying cylinder 701, the pine nuts in the conveying port of the positioning member 602 fall into the conveying cylinder 701. Under the guidance and limitation of the conveying cylinder 701, they move to the single feeding component, and the pine nuts are discharged one by one by the large feeding component.
[0085] It should be noted that the conveyor belt 601 is divided into a top surface and a bottom surface. The limiting plate 7 is intermittently fitted with the top surface inside the conveyor belt 601. This intermittent fit means that there is a small gap between the limiting plate 7 and the conveyor belt 601, so that the conveyor belt 601 does not come into contact with the limiting plate 7 during conveying, thus avoiding friction.
[0086] The single feeding assembly includes a guide pipe 702 fixed on the conveying bracket 1 and arranged at an angle, and the guide pipe 702 is connected to the conveying cylinder 701;
[0087] The bottom of the feed tube 702 is fixed with a receiving plate 8, and the receiving plate 8 is fixed with two second guide rods 802. Each of the two second guide rods 802 is slidably mounted with a baffle 801, and the baffle 801 is slidably engaged with the insertion slot 805 opened on the feed tube 702.
[0088] Springs 804 are fitted on both of the two guide rods 802. One end of the spring 804 is fixed to the baffle 801 and the other end is fixed to the guide rod 802.
[0089] An incomplete gear 803 is rotatably installed between the two baffles 801, and a second rack plate 806 is fixed on the opposite side of each of the two baffles 801. The second rack plate 806 cooperates with one of the second rack plates 806 or the other second rack plate 806.
[0090] A second motor 201 is fixed to the bottom of the receiving plate 8. The output shaft of the second motor 201 passes through the receiving plate 8 and is coaxially fixed with the incomplete gear 803.
[0091] In this embodiment of the invention, when the No. 2 motor 201 is working, it drives the incomplete gear 803 to rotate through its conveyor shaft.
[0092] Please see Figure 11 and Figure 6 In this embodiment, there are three conveying cylinders 701, which are named cylinder number one, cylinder number two, and cylinder number three from left to right. In fact, the two baffles 801 serve as a sealing effect. When pine nuts fall into the conveying cylinders 701, the pine nuts in cylinder number one will be discharged directly, while the pine nuts in cylinder number two and cylinder number three will be limited by the baffles 801. The two baffles 801 are named plate number one and plate number two, respectively.
[0093] When the incomplete gear 803 rotates, it drives the first plate that is blocking the second cylinder to move horizontally by meshing with one of the second rack plates 806, so as to release the blockage of the second cylinder, and the pine nuts inside are released from the limit and then discharged.
[0094] It should be noted that after the incomplete gear 803 drives the first plate blocking the second cylinder to move through meshing with the second rack plate 806, its continued rotation will not disengage the incomplete gear 803 from the second rack plate 806 of the first plate. Instead, it will continue to drive the first plate to move. In the subsequent rotation of the incomplete gear 803, it will mesh with the second rack plate 806 of the second plate to drive the second plate to move and unblock the third cylinder, thereby discharging the pine nuts from the third cylinder. This process is a single, one-time discharge.
[0095] Because the stroke of plate number one is relatively large, when the incomplete gear 803 disengages from the rack plate number two 806 of plate number one, the time required for its reset is greater than the time required for plate number two to open, thus enabling the pine nuts that were in cylinder number three before plate number one closed to pass through.
[0096] It should be noted that both baffles 801, namely plate number one and plate number two, will stretch the spring 804 during movement, so that after the incomplete gear 803 disengages from the rack plate number two, the baffles 801 will be reset by releasing the elastic potential energy stored in the spring 804 during stretching.
[0097] Of course, without considering cost, a control module can be installed on motor 201 to achieve a similar effect by driving it to rotate clockwise or counterclockwise.
[0098] One end of the guide tube 702 is also provided with a horizontally arranged conveying component 703, which is connected to the guide tube 702;
[0099] Among them, the top of the feed pipe 702 is equipped with a protective plate, and the conveying component 703 is partially exposed;
[0100] The conveying component 703 has a feeding plate 704 at one end away from the guide tube 702, and the opening mechanism is installed on the feeding plate 704.
[0101] The conveying component 703 is V-shaped, and the angle between the two sides is 60°.
[0102] In this embodiment of the invention, when pine nuts fall from the conveying cylinder 701 into the guide pipe 702, a protective plate is installed on the guide pipe 702 to prevent the pine nuts from falling due to bouncing. When the pine nuts move from the guide pipe 702 to the conveying component 703, they slide down and there is almost no bouncing problem. Therefore, no protective plate is installed on the conveying component 703.
[0103] Since the feed pipe 702 is inclined, the pine nuts have a certain inertia when they fall, so that the pine nuts can move to the end of the conveyor 703 and be received by the opening mechanism.
[0104] The opening mechanism includes a support plate 4 fixed to the bottom of the conveyor 703, and a limiting member is installed on the support plate 4 at the end of the conveyor 703;
[0105] The support plate 4 is also fixed with a plurality of first guide rods 406. A receiving seat 405 is slidably installed on the first guide rod 406. An opening clamp 409 is installed opposite to the receiving seat 405. The opening clamp 409 is slidably connected to the receiving seat 405 through a sliding groove 4016. Anti-slip texture 4010 is provided on the opposite side of the two opening clamps 409.
[0106] Both open clamps 409 are connected to a drive unit mounted on the receiving base 405;
[0107] An electric push rod 407 is fixed to the bottom of the support plate 4, and the movable rod of the electric push rod 407 is fixed to the receiving seat 405;
[0108] The width of both of the opening clamps 409 is smaller than the width of the slot 408.
[0109] In this embodiment of the invention, the two opening clamps 409 are driven by a driving member to reciprocate at a high frequency. The high-frequency relative motion of the two opening clamps 409 provides the squeezing force required to open the pine nuts. The stroke of the high-frequency reciprocating relative motion is relatively small.
[0110] When the pine nuts reach the end of the conveyor 703 due to the inertial motion of the pine nuts as they fall, the limiter limits the stroke of the pine nuts to prevent them from falling off the conveyor 703. Then, the electric push rod 407 drives the receiving seat 405 to rise, so that the pine nuts are squeezed by the opening clamp 409 with relative movement, so that the pine nuts complete the physical opening work.
[0111] Please see Figure 10 The opening clamp 409 rises within the feeding plate 704, and the width of the feeding plate 704 is greater than the thickness of the pine nut, so that the opening clamp 409 can rise at both ends of the pine nut and apply extrusion force to the pine nut.
[0112] It should also be noted that, in order to prevent the pine nuts from breaking apart due to their elastic potential energy when they are squeezed, the anti-slip texture 4010 provided on the opening clamp 409 can bite the pine nuts when force is applied, thus avoiding this problem.
[0113] The limiting component includes brackets 401 fixed on the support plate 4 and located on both sides of the conveyor 703. A travel limiting plate 404 is rotatably installed between the two brackets 401. Both ends of the travel limiting plate 404 are coaxially fixed with ratchet 403. On opposite sides of the two brackets 401, a pawl plate 402 that cooperates with the ratchet 403 in one direction is vertically and slidably installed. Both pawl plates 402 are fixed to the receiving seat 405.
[0114] The travel limiting plate 404 has a slot 408, the width of which is greater than the width of the opening clamp 409, and the width of which is less than the thickness of the pine nut.
[0115] In this embodiment of the invention, when the pine nut slides on the conveyor 703 due to inertia, the pine nut is limited by the travel limit plate 404. Since the width of the slot 408 is less than the thickness of the pine nut, the pine nut is stuck in the slot 408 to counteract its rebound force when it hits.
[0116] During this process, as the pine nut gets stuck in the slot 408, the receiving seat 405 and the opening clamp 409 will immediately fall after rising. This process will disengage the pine nut from the slot 408 and complete the opening operation. When the receiving seat 405 rises, the pawl plate 402 and the travel limit plate 404 do not have a transmission relationship, and therefore the travel limit plate 404 will not rotate. This allows the pawl plate 402 to descend when the receiving seat 405 descends. Through the cooperation of the pawl plate 402 and the ratchet 403, the travel limit plate 404 is driven to rotate at least 181°. Please refer to [link to relevant documentation]. Figure 12 When the travel limit plate 404 rotates 180°, subsequent rotations do not require power and can be completed by gravity. The subsequent 180° rotation will apply a knocking force to the pine nuts that have completed the opening process, so that the pine nuts are driven by external force to continue moving, thereby completing the discharge process after the opening. Since the pine nuts are under the limit guidance of the conveyor 703, the discharge position is specified.
[0117] It should be noted that after the travel limit plate 404 rotates 180°, it will rotate another 180° due to gravity and inertia. This rotation will exceed 180° and then reciprocate, which is to say, swing. When swinging back and forth, it will be locked in the vertical position by the cooperation of the ratchet 403 and the pawl plate 402.
[0118] Since the pawl plate 402 consists of a pawl and a transmission plate, the pawl must be equipped with a torsion spring to achieve unidirectional transmission. The elastic potential energy of the torsion spring is used to counteract the force of the swing of the travel limit plate 404.
[0119] Since the ratchet and pawl structure is a very mature existing technology, it will not be described in detail here.
[0120] The driving component includes a gear 4014 and a transmission disk 4012 rotatably mounted on the support 405. A transmission rod 4013 is rotatably mounted at the offset position of the transmission disk 4012, and the transmission rod 4013 is rotatably connected to the eccentric position of the gear 4014.
[0121] Both of the two opening clamps 409 are fixed with a first rack plate 4011 that meshes with the gear 4014. The receiving seat 405 is also fixed with a third motor 4015. The output shaft of the third motor 4015 is coaxially fixed with the transmission disk 4012.
[0122] In this embodiment of the invention, when the No. 3 motor 4015 is working, it drives the transmission disk 4012 to rotate through its output shaft. When the transmission disk 4012 rotates, it drives the gear 4014 to reciprocate through the transmission rod 4013. When the gear 4014 rotates, it drives the two open clamps 409 to reciprocate relative to each other through meshing with the two No. 1 rack plates 4011.
[0123] In this way, when the transmission disc 4012 rotates, the transmission rod 4013 drives the gear 4014, which can drive the gear 4014 to reciprocate at high frequency when the transmission disc 4012 rotates at high speed. The reciprocating amplitude of the gear 4014 can be adjusted by adjusting the deflection distance of the transmission rod 4013.
[0124] It should also be noted that the No. 3 motor 4015 in this invention is a high-speed DC motor. Of course, a stepper motor or servo motor can also be used depending on actual needs. This invention does not impose specific limitations, as long as the driving requirements are met.
[0125] The support arm 301 is also equipped with a controller 5, which has an adjustment panel 501. The motor, electric push rod and other electronic components required by the equipment involved in this invention are all connected to the controller 5, and the parameters are adjusted through the adjustment panel 501.
[0126] This invention also provides an adjustable intelligent conveying method for a pine nut opening machine, employing the aforementioned adjustable intelligent conveying mechanism for a pine nut opening machine, comprising the following steps:
[0127] Step 1: The pine nuts are sorted and transported using a conveyor mechanism;
[0128] Step 2: The single feeding component is used to feed pine nuts in a single operation. During this process, the pine nuts are arranged with the specified edge facing the bottom of the conveyor 703.
[0129] Step 3: Open the pine nuts using the opening mechanism and then place them in the designated location.
[0130] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0131] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
