Description

Technical Field

[0001] The invention relates to the field related to pine nut processing, and in particular to an adjustable intelligent conveying mechanism and method for a pine nut opening machine. Background Art

[0002] Pine nuts, also known as pine nuts, fruit pine nuts, and maritime pine nuts, are the seeds of Pinus koraiensis and other plants in the Pinaceae family. They are one of the common nuts and are rich in fat, protein, carbohydrates, etc. They are an important Chinese medicine. Long-term consumption can strengthen the body and mind, moisturize the skin, prolong life, and also has high therapeutic value.

[0003] Since pine nuts are in a closed state after being taken from the pine cone, they are not easy to eat. Since pine nut foods are different from melon seeds, their shells are thicker. In order to facilitate eating, manufacturers usually open the pine nuts for easy consumption. There are two widely used methods, one is frying, and the other is heating and then cooling, opening by thermal expansion and contraction. For example, a fully automatic pine nut opening conveying device has been disclosed, with announcement number: CN112790398A. Both of these methods will have a certain impact on the kernels of the pine nuts, and will affect the taste and flavor of the kernels. At present, some high-quality pine nuts are opened by physical squeezing in order to ensure the taste and flavor of the pine nuts. The current conveying equipment does not have a conveying device that limits the position of the pine nuts, so that the pine nuts can be conveyed in a specified posture to facilitate the opening of the opening device. For example, the above patent does not limit the posture of the pine nuts during the conveying process, so that the push block cannot squeeze the nuts when moving, and may cause a jamming phenomenon; This patent realizes the squeezing of pine nuts by squeezing blocks, and the squeezing blocks are respectively located at four directions: three o'clock, nine o'clock, six o'clock, and twelve o'clock. Since the pine nuts are not limited, they may also be at eleven o'clock and five o'clock. The opening squeezing work in this position must be unstressed, which obviously needs to be improved. Secondly, the patent does not provide a solution on how to implement the release of electrons into the storage tube. Summary of the invention

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0031] For example, see Figures 1 to 12 , an adjustable intelligent conveying mechanism for a pine nut opening machine, comprising a conveying bracket 1 and protective covers 101 installed on both sides of the conveying bracket 1, and also comprising a conveying mechanism installed on the conveying bracket 1, through which the pine nuts are conveyed in a specified state; A single feeding assembly, which is installed in the conveying bracket 1 and cooperates with the conveying mechanism to convey the pine nuts one by one in a specified posture; An opening mechanism is installed on one side of the conveying bracket 1 and cooperates with the single feeding component. The pine nuts conveyed by the single feeding component are opened and discharged through the opening mechanism.

[0032] In the embodiment of the present invention, the pine nuts are positioned and conveyed to a single feeding assembly by a conveying mechanism, and the posture of the pine nuts in this process changes from random to specified; The pine nuts in a single feeding component will be transported one by one to the opening mechanism, and the pine nuts will be opened by the opening mechanism and discharged to the designated position after the opening is completed.

[0033] The conveying mechanism comprises two conveying rollers 6 rotatably mounted on the conveying bracket 1, and the two conveying rollers 6 are connected by a conveying belt 601; The conveyor belt 601 is provided with a plurality of openings equidistantly along the conveying direction, and a plurality of positioning members 602 are fixed equidistantly along the conveying direction on the conveyor belt 601, and the positioning members 602 are provided with conveying openings, and the conveying openings and the openings are arranged concentrically with the conveying openings of the positioning members 602; Wherein, the through opening and the delivery opening of the positioning member 602 are both elliptical in configuration; A first motor 2 is fixed to one side of the conveying bracket 1 , and an output shaft of the first motor 2 is coaxially fixed to a rotating shaft of one of the conveying rollers 6 .

[0034] In the embodiment of the present invention, when the No. 1 motor 2 is working, one of the conveying rollers 6 is driven to rotate through its conveying shaft, so that when one of the conveying rollers 6 rotates, the other conveying roller 6 is driven to rotate by driving the conveying belt 601 to rotate, so that the two conveying rollers 6 are synchronously rotated in the same direction to convey the conveying belt 601, and the positioning member 602 is driven to rotate through the conveying of the conveying belt 601; Among them, it should be noted that the No. 1 motor 2 in this embodiment adopts a servo motor. Of course, a stepper motor or a DC motor can also be selected according to actual production needs to meet the driving requirements. The present invention does not make specific limitations.

[0035] The conveying bracket 1 is provided with a material storage box 3, and the material storage box 3 is fixed to the conveying bracket 1 through supporting arms 301 fixed on both sides; The bottom of the storage box 3 is provided with a plurality of discharge holes 303 cooperating with the positioning member 602, and both sides of the plurality of discharge holes 303 are provided with arc surfaces 304 for limiting the shape of the pine nuts, and the discharge holes 303 have the same shape as the conveying hole of the positioning member 602; The material storage box 3 is provided with a discharge hole 303 .

[0036] In the present 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 toward the discharge hole 303; The delivery in the storage box 3 will be limited by the arc surface 304, so that its edge moves toward the discharge hole 303, so that the pine nuts fall through the discharge hole 303 with the edge facing downward or upward, and move to the delivery port of the positioning member 602 when the pine nuts fall through the discharge hole 303, and move through the positioning member 602 and the conveying of the positioning member 602 to carry the pine nuts; Among them, since the thickness of the pine nuts is smaller than the width and the shape is similar to an ellipse, the pine nuts are inclined under the limitation of the arc surface 304, and the ellipse shape of the upper discharge hole 303 and the conveying hole of the positioning member 602 is limited, so that the pine nuts can be delivered to the discharge hole 303 and the conveying hole of the positioning member 602 in a specified state; It should also be noted that a stirring structure may be installed in the storage box 3 to prevent the accumulation of pine nuts which may lead to a decrease in the energy of pine nut movement. Since the stirring structure is relatively simple to implement, the stirring structure used is not specifically limited in the present invention.

[0037] A limiting plate 7 is fixed inside the conveying bracket 1. The limiting plate 7 is inside the conveying belt 601 and is gap-matched with the conveying belt 601. A conveying cylinder 701 is fixed to the end of the limiting plate 7. The conveying cylinder 701 matches with the conveying hole of the positioning member 602 and the through-opening of the conveying belt 601, and the conveying cylinder 701 also matches with the single feeding assembly.

[0038] In the embodiment of the present invention, when the pine nuts are in the conveying hole of the positioning member 602, the conveying of the conveyor belt 601 drives the positioning member 602 and the pine nuts to move toward the conveying cylinder 701; Among them, when the pine nuts are sent to the position of the conveying cylinder 701, the pine nuts are limited by the limiting plate 7 to prevent the pine nuts from falling during the conveying process. When the same mouth of the conveying belt 601 and the conveying hole of the positioning member 602 move to be concentric with the conveying cylinder 701, the nuts in the conveying hole of the positioning member 602 fall into the conveying cylinder 701, and move to the single feeding assembly under the guidance and limitation of the conveying cylinder 701, and the pine nuts are discharged one by one through the large feeding assembly. It should be noted that the conveyor belt 601 is divided into a top surface and a bottom surface, and the limit plate 7 is intermittently matched with the top surface inside the conveyor belt 601. The clearance fit is such that there is a small gap between the limit plate 7 and the conveyor belt 601. When the conveyor belt 601 is conveying, it does not contact the limit plate 7 to avoid friction.

[0039] The single material feeding assembly includes a material guide pipe 702 fixed on the conveying bracket 1 and arranged obliquely, and the material guide pipe 702 is connected to the conveying cylinder 701; A receiving plate 8 is fixed at the bottom of the guide tube 702, and two No. 2 guide rods 802 are fixed on the receiving plate 8. Baffles 801 are slidably mounted on the two No. 2 guide rods 802, and the baffles 801 are slidably matched with the insertion grooves 805 provided on the guide tube 702; The two second guide rods 802 are both sleeved with a spring 804, one end of the spring 804 is fixed to the baffle 801 and the other end is fixed to the second guide rod 802; An incomplete gear 803 is rotatably mounted between the two baffles 801, and a second rack plate 806 is fixed to opposite sides of the two baffles 801, and the second rack plate 806 cooperates with one of the second rack plates 806 or the other second rack plate 806; A second motor 201 is fixed at the bottom of the receiving plate 8 , and an output shaft of the second motor 201 passes through the receiving plate 8 and is coaxially fixed with the incomplete gear 803 .

[0040] In the embodiment of the present invention, when the second motor 201 is working, the incomplete gear 803 is driven to rotate through its conveying shaft; See also Fig.11and Figure 6 In this embodiment, there are three conveying cylinders 701, which are named No. 1 cylinder, No. 2 cylinder and No. 3 cylinder from left to right. In fact, the two baffles 801 play a blocking effect. When pine nuts fall into the conveying cylinder 701, the pine nuts in the No. 1 cylinder will be directly discharged, while the pine nuts in the No. 2 cylinder and the No. 3 cylinder will be limited by the baffles 801, and the two baffles 801 are named No. 1 plate and No. 2 plate respectively. When the incomplete gear 803 rotates, it meshes with one of the second rack plates 806 to drive the first plate that blocks the second tube to move horizontally, so as to release the blockage of the second tube, and the pine nuts inside it contact the limit position and are discharged; It should be noted that after the incomplete gear 803 drives the No. 1 plate that blocks the No. 2 barrel to move by meshing with the No. 2 rack plate 806, continued rotation does not disengage the incomplete gear 803 from the No. 2 rack plate 806 of the No. 1 plate, but continues to drive the No. 1 plate to move until the incomplete gear 803 meshes with the No. 2 rack plate 806 of the No. 2 plate during subsequent rotation, driving the No. 2 plate to move and unblock the No. 3 barrel, thereby discharging the pine nuts in the No. 3 barrel. This process is a single discharge. Since the stroke of the first plate is relatively large, when the incomplete gear 803 is disengaged from the second rack plate 806 of the first plate, the time required for its reset is longer than the time for the second plate to open, thereby enabling the pine nuts in the third cylinder to pass before the first plate is closed; It should be noted that the two baffles 801, namely the first plate and the second plate, will pull up the spring 804 when they move, so that after the incomplete gear 803 is disengaged from the second rack plate 806, the baffle 801 is reset by releasing the elastic potential energy stored when the spring 804 is pulled up; Of course, without considering the cost, a control module can be installed for the second motor 201 to achieve a similar effect by driving it to rotate clockwise or counterclockwise.

[0041] One end of the material guide tube 702 also has a horizontally arranged conveying member 703, and the conveying member 703 is connected to the material guide tube 702; Among them, a protective plate is installed on the top of the guide pipe 702, and the conveying member 703 is partially exposed; The conveying member 703 is provided with a feeding plate 704 at one end away from the material guide tube 702, and the opening mechanism is installed on the feeding plate 704; The conveying member 703 is arranged in a V shape, and the angle between the two sides is 60°.

[0042] In the embodiment of the present invention, when the pine nuts fall into the guide tube 702 through the conveying cylinder 701, a protective plate is provided on the guide tube 702 to prevent the pine nuts from falling due to bouncing. However, when the pine nuts move from the guide tube 702 to the conveying member 703, the pine nuts slide and there is almost no bouncing problem. Therefore, no protective plate is provided on the conveying member 703. Since the guide tube 702 is arranged at an angle, the pine nuts have a certain inertia when they slide down, and the inertia causes the pine nuts to move to the end of the conveying member 703 and be received by the opening mechanism.

[0043] The opening mechanism comprises a support plate 4 fixed to the bottom of the conveying member 703, and a limiting member is installed on the support plate 4 at the end of the conveying member 703; The support plate 4 is also fixed with a plurality of No. 1 guide rods 406, on which a travel limit plate 404 is slidably mounted, on which a receiving seat 405 is slidably mounted, and on which an opening clamp 409 is relatively mounted, and the opening clamp 409 is slidably connected to the receiving seat 405 through a sliding groove 4016, and anti-slip grooves 4010 are arranged on opposite sides of two opening clamps 409; The two opening clamps 409 are connected to the driving member installed on the receiving seat 405; An electric push rod 407 is fixed to the bottom of the receiving seat 405, and a movable rod of the electric push rod 407 is fixed to the receiving seat 405; The widths of the two opening clamps 409 are both smaller than the width of the electric push rod 407 .

[0044] In the embodiment of the present invention, the two opening clamps 409 are driven to reciprocate relative to each other at a high frequency by a driving member, and the high-frequency relative movement of the two opening clamps 409 is used to provide the squeezing force required for opening the pine nuts, and the stroke of the high-frequency reciprocating relative movement is relatively small; When the pine nuts reach the end of the conveying member 703 due to the inertial movement when sliding down, the pine nuts are limited by the limiter to prevent them from falling off the conveying member 703, and then the receiving seat 405 is driven to rise by the electric push rod 407 to squeeze the pine nuts through the relatively moving opening clamp 409, so that the pine nuts are physically opened; See also Fig.10 , wherein the opening clamp 409 is raised inside the feeding plate 704, and the width of the feeding plate 704 is greater than the thickness of the pine nuts, so that the opening clamp 409 can be located at both ends of the pine nuts to exert a squeezing force on the pine nuts; It should also be noted that in order to prevent the elastic potential energy of the pine nuts from collapsing when they are deformed when squeezed, anti-slip grooves 4010 are provided on the opening clamp 409 to bite the pine nuts when force is applied, thereby avoiding the occurrence of this problem.

[0045] The limiting member includes a bracket 401 fixed on the support plate 4 and located on both sides of the conveying member 703, a travel limiting plate 404 is rotatably installed between the two brackets 401, ratchet wheels 403 are coaxially fixed to both ends of the travel limiting plate 404, and ratchet plates 402 that unidirectionally cooperate with the ratchet wheels 403 are vertically and slidably installed on opposite sides of the two brackets 401, and the two ratchet plates 402 are fixed to the receiving seat 405; The travel limit plate 404 is provided with 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 a pine nut.

[0046] In the embodiment of the present invention, when the pine nut slides on the conveying member 703 due to inertia, the pine nut is limited by the travel limit plate 404. Since the width of the notch 408 is smaller than the thickness of the pine nut, the pine nut is stuck in the notch 408 to offset the rebound force when it hits. In this process, since the pine nut is stuck in the notch 408, the receiving seat 405 and the opening clamp 409 will fall immediately after rising. This process will cause the pine nut to disengage from the notch 408 and complete the opening work. When the receiving seat 405 rises, the ratchet plate 402 and the travel limit plate 404 do not have a transmission relationship, and then the travel limit plate 404 will not rotate, so that when the receiving seat 405 descends, the ratchet plate 402 is driven to descend, and the travel limit plate 404 is driven to rotate at least 181° through the cooperation of the ratchet plate 402 and the ratchet wheel 403. Please refer to Fig.12 When the travel limit plate 404 rotates 180°, the subsequent rotation does not require power, and the subsequent 180° rotation can be completed by gravity, and the subsequent 180° rotation will apply a knocking force to the delivery that has completed the opening work, so that the delivery is driven by external force to continue moving, thereby completing the discharge work after the opening, and because the delivery is under the limit guide of the conveying member 703, the discharge position is specified; It should be noted that after the travel limit plate 404 rotates 180°, it will rotate another 180° due to gravity and inertia. After the rotation exceeds 180°, it will reciprocate, that is, swing. When it swings back and forth, it will be locked in the upright state through the cooperation of the ratchet wheel 403 and the pawl plate 402. Since the pawl plate 402 is a pawl and a transmission plate, a torsion spring must be installed to realize one-way transmission of the pawl, and the elastic potential energy of the torsion spring is used to offset the swing force of the travel limit plate 404; Since the ratchet pawl structure is a very mature prior art, it will not be elaborated in detail here.

[0047] The driving member includes a gear 4014 and a transmission plate 4012 rotatably mounted on a receiving seat 405, a transmission rod 4013 is rotatably mounted on an eccentric portion of the transmission plate 4012, and the transmission rod 4013 is rotatably connected to an eccentric portion of the gear 4014; A No. 1 rack plate 4011 meshing with a gear 4014 is fixed to each of the two opening clamps 409 , and a No. 3 motor 4015 is also fixed to the receiving seat 405 , and the output shaft of the No. 3 motor 4015 is coaxially fixed to the transmission disc 4012 .
