Description

Technical Field

[0001] This invention relates to the field of conveying device technology, and in particular to an automated conveying device and method based on jujube processing. Background Technology

[0002] In the process of processing jujubes, it is necessary to remove the pits. Jujube pits not only cannot provide edible value, but also become "obstacles" in many stages such as processing, consumption, and safety. Whether it is primary processing (such as grading dried dates), deep processing (such as date paste, date jam, and date powder), or end consumption (such as ready-to-eat dates and baking ingredients), pitting is a key prerequisite for maximizing the value of jujubes and avoiding core risks.

[0003] During the process of pitting jujubes, the jujubes need to be transported to the pitting area by a conveyor device, and the pitting device is used to remove the pits from the jujubes.

[0004] When pitting jujubes, the pitting punch is usually aligned with the center of the jujube to push out the pit. However, in actual pitting, due to the different particle sizes of jujubes, the punch may not be able to be aligned with the center of the jujube during the feeding process, resulting in pitting deviation. This can easily affect the pitting effect and thus the quality of the produced jujubes. Summary of the Invention

[0005] The purpose of this invention is to provide an automated conveying device for jujube processing, which ensures that the center of the circle between the two clamping frames coincides with the axis of the pitting punch. Since the clamping frames hold the jujube in the middle position, the pitting punch can be easily aligned with the middle position of the jujube. This reduces pitting deviation when the pitting punch removes the pit from the jujube, thereby improving the pitting effect and the quality of the produced jujubes, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automated conveying device for jujube processing, comprising a conveyor frame, a conveyor belt disposed on the outer side of the conveyor frame, a pitting component disposed on the rear side of the conveyor frame, a drop groove formed on the surface of the conveyor belt, and an alignment component disposed inside the drop groove.

The drive assembly includes a slot opened inside the conveyor belt, a first piston is movably connected inside the slot, a lifting shaft is fixedly connected to the bottom of the first piston, and the end of the lifting shaft passes through the conveyor belt. The drive assembly also includes a cylinder fixedly connected inside the conveyor belt, a second piston is movably connected inside the cylinder, a support rod is fixedly connected to the top of the second piston, a bending frame is fixedly connected to the top of the support rod, the outside of the bending frame is slidably connected to the conveyor belt, and the bending frame is fixedly connected to the lifting plate near the lifting plate. A connecting pipe is fixedly inserted between the cylinder and the slot.

[0008] Preferably, a first spring is fixedly connected between the top of the first piston and the conveyor belt, and a ball bearing for reducing motion friction is rotatably connected to the end of the lifting shaft.

[0009] Preferably, a clamping assembly is disposed above the lifting plate. The clamping assembly includes an elastic bladder fixedly connected to the inside of the clamping frame. The clamping assembly also includes a push plate slidably connected to the inside of the frame. A top moving frame is fixedly connected below the push plate. The inside of the frame is connected to a connecting pipe and a mounting block. A first flexible tube is fixedly inserted between the connecting pipe and the elastic bladder.

[0010] Preferably, a second spring is fixedly connected between the top of the frame and the conveyor belt, and the elastic force of the second spring is greater than that of the elastic bladder.

[0011] Preferably, a torsion spring is fixedly connected between the middle position of the connecting pipe and the mounting pipe bracket.

[0012] Preferably, the core removal assembly includes an electric telescopic rod fixedly connected to the rear side of the conveyor frame, the output shaft of the electric telescopic rod is fixedly connected to a horizontal plate, and a core removal punch is fixedly connected to the front side of the horizontal plate.

[0013] Preferably, the conveyor belt is internally configured with a swing assembly. The swing assembly includes a long strip fixedly connected to the rear side of the mounting tube frame. A collar is fixedly connected to the rear side of the long strip. The inner side of the collar is rotatably connected to the connecting pipe. A small plate is fixedly connected to the bottom of the collar. A swing rod is fixedly connected to the side of the small plate. The swing assembly also includes a sleeve fixedly connected to the inside of the mounting block. A third piston is movably connected inside the sleeve. A round shaft is fixedly connected to the side of the third piston. A mounting plate is fixedly connected to the end of the round shaft.

[0014] Preferably, a third spring is fixedly connected between the sleeve and the third piston, and a second flexible tube is fixedly inserted between the sleeve and the long groove.

[0015] An automated conveying method based on jujube processing includes the following steps: S1, Material dropping: The red dates fall into the inside of the trough; S2. Conveying: The jujubes are transported to the location where they need to be processed via a conveyor belt.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. When the clamping frame moves the jujube to the top position, the center of the circle between the two clamping frames coincides with the axis of the pitting punch. Since the clamping frame holds the jujube in the middle position, it is easy for the pitting punch to be aligned with the middle position of the jujube. This reduces the pitting deviation when the pitting punch removes the pit from the jujube, thereby improving the pitting effect and thus improving the quality of the produced jujube. 2. After the elastic bladder expands, it will squeeze the red dates to the middle position of the clamping frame, ensuring that the middle position of the red dates is in the middle position of the clamping frame 55, further reducing the deviation of pitting, thereby improving the pitting effect of red dates and thus improving the quality of the produced red dates; 3. When rotating back and forth in small amplitudes, the contact between the pitting tool and the fruit pulp is continuous and gradual. The jujube constantly adjusts its posture with the swing, and the impact force is gradually dispersed to different parts of the fruit pulp rather than concentrated at one point. This avoids local stress concentration, and the fruit pulp integrity rate can be improved to a higher level, greatly reducing raw material waste and further improving the pitting effect of jujubes.

[0020] 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.

[0021] Example 1: Please refer to Figures 1 to 11 The present invention provides a technical solution: an automated conveying device for processing jujubes, including a conveyor frame 1, a conveyor belt 2 arranged on the outer side of the conveyor frame 1, a pitting component 3 arranged on the rear side of the conveyor frame 1, a drop groove 4 opened on the surface of the conveyor belt 2, and the pitting component 3 including an electric telescopic rod 31 fixedly connected to the rear side of the conveyor frame 1, a horizontal plate 32 fixedly connected to the output shaft of the electric telescopic rod 31, and a pitting punch 33 fixedly connected to the front side of the horizontal plate 32.

[0022] By adopting the above technical solution, the conveyor belt 2 is made of metal, which has strong rigidity. It adopts a modular structure and is spliced ​​together from multiple metal chain links or mesh panels. This technology is a mature existing technology and will not be described in detail. A material dropping component is fixedly installed on the left side of the conveyor frame 1. The material dropping component can evenly drop individual red dates into the inside of the dropping trough 4, and the ends of the red dates are in the front-back direction. It should be noted that the size of the dropping trough 4 is larger than the size of the red dates. The transmission method of the conveyor belt 2 is a mature existing technology and will not be described in detail.

[0023] The jujubes are conveyed by the conveyor belt 2 to the pitting punch 33. When the jujubes reach the appropriate position, the conveyor belt 2 stops conveying. The output shaft of the electric telescopic rod 31 extends, which allows the horizontal plate 32 to move forward with the pitting punch 33 to remove the pits from the jujubes.

[0024] It should be noted that multiple pitting punches 33 are installed on the horizontal plate 32, and the distance between adjacent pitting punches 33 is the same as the distance between adjacent drop grooves 4, so as to complete the pitting operation of jujubes in one go.

[0025] The automated conveying device also includes an alignment component 5 disposed inside the drop trough 4. The alignment component 5 includes a frame 51 slidably connected inside the drop trough 4. A mounting block 52 is fixedly connected to the top of the frame 51. A connecting pipe 53 is fixedly inserted into the mounting block 52. A mounting pipe bracket 54 is rotatably connected to the middle position of the connecting pipe 53. A clamping frame 55 is rotatably connected to the outside of the connecting pipe 53. Two clamping frames 55 are provided. A lifting plate 56 is disposed below the frame 51. An extrusion frame 57 is fixedly connected to the top two sides of the lifting plate 56. A rotating shaft for reducing motion friction is rotatably connected to the top of the extrusion frame 57. A drive component 6 for driving the lifting plate 56 to move up and down is disposed inside the conveyor belt 2.

[0026] A limiting plate 10 is fixedly connected to the inner side of the conveyor frame 1. The limiting plate 10 is inclined on the side. The drive assembly 6 includes a slot 61 opened inside the conveyor belt 2. A first piston 62 is movably connected inside the slot 61. A lifting shaft 63 is fixedly connected to the bottom of the first piston 62. The end of the lifting shaft 63 extends out from the conveyor belt 2. The drive assembly 6 also includes a cylinder 64 fixedly connected inside the conveyor belt 2. A second piston 65 is movably connected inside the cylinder 64. A support rod 66 is fixedly connected to the top of the second piston 65. A bending frame 67 is fixedly connected to the top of the frame 6. The outside of the bending frame 67 is slidably connected to the conveyor belt 2. The bending frame 67 is fixedly connected to the lifting plate 56 near the lifting plate 56. A connecting pipe 68 is fixedly inserted between the cylinder 64 and the empty groove 61. A first spring 69 is fixedly connected between the top of the first piston 62 and the conveyor belt 2. A ball for reducing motion friction is rotatably connected to the end of the lifting shaft 63. The diameter of the empty groove 61 is larger than the diameter of the cylinder 64. A second spring 9 is fixedly connected between the top of the frame 51 and the conveyor belt 2.

[0027] A torsion spring 11 is fixedly connected between the middle position of the connecting pipe 53 and the mounting pipe bracket 54.

[0028] By adopting the above technical solution, when the lifting shaft 63 has not moved to the position of the limiting plate 10, under the elastic force of the first spring 69, the lifting shaft 63 and the first piston 62 are in a lower position, which allows the bending frame 67 to be located at the bottom position. Under the elastic force of the second spring 9, the frame 51 is in a smaller position. At this time, the top of the bending frame 67 near the frame 51 does not contact the bottom of the frame 51. Under the gravity of the clamping frame 55, the two clamping frames 55 deflect to both sides, thereby making the two clamping frames 55 open.

[0029] Since the two clamps 55 are open in the initial state, when the jujube falls into the groove 4, it can fall inside the two clamps 55.

[0030] As the conveyor belt 2 conveys the material, when the lifting shaft 63 moves to the position of the limiting plate 10, the limiting plate 10 limits the lifting shaft 63, allowing the lifting shaft 63 to move upward with the first piston 62 overcoming the elastic force of the second spring 9. At this time, the medium inside the empty trough 61 enters the interior of the cylinder 64 through the connecting pipe 68. Under the pressure of the medium, the second piston 65 moves upward with the support rod 66, thereby causing the bending frame 67 to move upward. As the bending frame 67 moves upward, it can also move the lifting plate 56 upward. At this time, the extrusion frame 57 moves upward accordingly. The rotating shaft at the top of the extrusion frame 57 extrudes the clamping frame 55. During this process, the clamping frame 55 is extruded and gradually closes to clamp and limit the jujubes. After the side clamping frame 55 closes, the top surface of the lifting plate 56 fits against the top of the frame 51. As the bending frame 67 continues to move upward, the lifting plate 56 continues to move upward, squeezing the frame 51. This causes the frame 51 to overcome the elastic force of the second spring 9 and move upward, causing the clamping frame 55 to move upward with the jujube. It should be noted that when the clamping frame 55 moves with the jujube to the uppermost position, the center between the two clamping frames 55 coincides with the axis of the pitting punch 33. Since the clamping frame 55 holds the jujube in the middle position, it is easy for the pitting punch 33 to be aligned with the middle position of the jujube. This reduces the pitting deviation when the pitting punch 33 removes the pit from the jujube, thereby improving the pitting effect and improving the quality of the produced jujube.

[0031] A clamping assembly 7 is configured above the lifting plate 56. The clamping assembly 7 includes an elastic bladder 71 fixedly connected to the inside of the clamping frame 55. The clamping assembly 7 also includes a push plate 72 slidably connected inside the frame 51. A top-moving frame 73 is fixedly connected below the push plate 72. The inside of the frame 51 is connected to the connecting pipe 53 and the mounting block 52. A first flexible tube 74 is fixedly inserted between the connecting pipe 53 and the elastic bladder 71. The elastic force of the second spring 9 is greater than the elastic force of the elastic bladder 71. A rubber strip is fixedly connected to the outside of the push plate 72 to ensure the sealing performance between the outside of the push plate 72 and the inside of the frame 51.

[0032] By adopting the above technical solution, in the initial state, due to the elastic force of the elastic bladder 71, the top moving frame 73 is located at a lower position. When the lifting plate 56 moves upward in the initial state, the lifting plate 56 squeezes the bottom of the top moving frame 73. Since the elastic force of the second spring 9 is greater than the elastic force of the elastic bladder 71, the top moving frame 73 moves upward with the push plate 72, which allows the medium inside the frame 51 to enter the interior of the first flexible tube 74, the mounting block 52 and the connecting tube 53, and then enter the interior of the elastic bladder 71, so as to realize the expansion of the elastic bladder 71 to clamp the jujube and ensure the clamping effect of the jujube.

[0033] It should be noted that after the elastic bladder 71 expands, it will squeeze the red dates towards the middle position of the clamping frame 55, ensuring that the middle position of the red dates is in the middle position of the clamping frame 55, further reducing the deviation in pitting, thereby improving the pitting effect of the red dates and thus improving the quality of the produced red dates.

[0034] The conveyor belt 2 is internally equipped with a swing assembly 8. The swing assembly 8 includes a long strip 81 fixedly connected to the rear side of the mounting tube 54. A collar 82 is fixedly connected to the rear side of the long strip 81. The inner side of the collar 82 is rotatably connected to the connecting tube 53. A small plate 83 is fixedly connected to the bottom of the collar 82. A swing rod 84 is fixedly connected to the side of the small plate 83. The swing assembly 8 also includes a sleeve 85 fixedly connected inside the mounting block 52. A third piston 86 is movably connected inside the sleeve 85. A round shaft 87 is fixedly connected to the side of the third piston 86. A mounting plate 88 is fixedly connected to the end of the round shaft 87. The mounting plate 88... A protruding strip 89 is fixedly connected in a linear array on one side near the swing arm 84. The side of the protruding strip 89 is arc-shaped. The swing assembly 8 also includes a long groove 810 opened inside the conveyor belt 2. A fourth piston 811 is movably connected inside the long groove 810. A motion frame 812 is fixedly connected to the side of the fourth piston 811. The motion frame 812 extends from the rear side of the conveyor belt 2. A third spring 813 is fixedly connected between the sleeve 85 and the third piston 86. A second flexible tube 814 is fixedly inserted between the sleeve 85 and the long groove 810. A ball bearing for reducing motion friction is rotatably connected to the end of the swing arm 84.

[0035] Under the elastic force of the torsion spring 11, the clamp 55 can be positioned directly above the connecting tube 53.

[0036] It should be noted that the diameter of the sleeve 85 is larger than the diameter of the long groove 810. When the moving frame 812 moves a longer distance, the round shaft 87 will move a shorter distance.

[0037] By adopting the above technical solution, when pitting is required, the output shaft of the electric telescopic rod 31 extends, allowing the horizontal plate 32 to move the pitting punch 33 forward. When the pitting punch 33 is about to contact the jujube, the horizontal plate 32 contacts the end of the moving frame 812. As the output shaft of the electric telescopic rod 31 continues to extend, the moving frame 812 is compressed, causing the third piston 86 to move forward. During this process, the medium inside the long groove 810 enters the interior of the second flexible tube 814, and then the medium enters the sleeve 85. Inside, the third piston 86, along with the round shaft 87, can move forward against the elastic force of the third spring 813. At this time, the mounting plate 88, along with the protrusion 89, can move forward. When one of the protrusions 89 limits the swing rod 84, it can squeeze the swing rod 84, thereby causing the swing rod 84 to deflect along with the small plate 83. This causes the collar 82 to rotate outside the connecting pipe 53, and the long strip 81 to rotate along with the mounting pipe bracket 54, thereby causing the clamping frame 55 to rotate along with the clamped jujube.

[0038] When the protrusion 89 has completely passed the swing rod 84, under the elastic force of the torsion spring 11, the mounting tube 54, along with the clamping frame 55 and the clamped jujube, rotates and resets. This design allows the jujube to rotate back and forth in small amplitudes continuously during the process of pitting the jujube.

[0039] The flesh of jujubes is soft, especially the flesh near the pit, which is even thinner. When pitting jujubes statically, the impact force of the pitting tool is concentrated on a single point in the flesh, which can easily lead to local tearing and damage. When rotating back and forth with small amplitude, the contact between the pitting tool and the flesh is continuous and gradual. As the jujubes swing and adjust their posture, the impact force is gradually dispersed to different parts of the flesh, rather than concentrated on one point. This avoids local stress concentration, increases the integrity rate of the flesh to a higher level, significantly reduces raw material waste, and further improves the pitting effect of jujubes.

[0040] An automated conveying method based on jujube processing includes the following steps: S1, Dropping: Drop individual red dates into the trough 4, with the ends of the red dates facing the front-back direction; S2. Conveying: The jujubes are conveyed to the pitting punch 33 via the conveyor belt 2. When the jujubes reach the appropriate position, the conveyor belt 2 stops conveying. The output shaft of the electric telescopic rod 31 extends, allowing the horizontal plate 32 to move forward with the pitting punch 33 to remove the pits from the jujubes.

[0041] Working principle: Initially, the two clamping frames 55 are open. When the jujubes fall into the trough 4, they fall inside the clamping frames 55. As the conveyor belt 2 moves, when the lifting shaft 63 reaches the position of the limiting plate 10, the limiting plate 10 limits the lifting shaft 63. This allows the lifting shaft 63 to move upwards, carrying the first piston 62 against the elastic force of the second spring 9. At this time, the medium inside the empty trough 61 enters the cylinder 64 through the connecting pipe 68. Under the pressure of the medium, the second piston 65 moves upwards, carrying the support rod 66. This causes the bending frame 67 to move upwards, which in turn moves the lifting plate 56 upwards. At this time, the pressing frame 57 moves upwards accordingly. During the upward movement, the rotating shaft at the top of the squeezing frame 57 squeezes the clamping frame 55. During this process, the clamping frame 55 is squeezed and gradually closes to clamp and limit the jujube. When the clamping frames 55 on both sides close, the top surface of the lifting plate 56 is in contact with the top of the frame 51. As the bending frame 67 continues to move upward, the lifting plate 56 continues to move upward to squeeze the frame 51, causing the frame 51 to overcome the elastic force of the second spring 9 and move upward, so that the clamping frame 55 carries the jujube upward. It should be noted that when the clamping frame 55 carries the jujube to the uppermost position, the center between the two clamping frames 55 coincides with the axis of the pitting punch 33. Since the clamping frame 55 clamps the jujube in the middle position, it is easy for the pitting punch 33 to be aligned with the middle position of the jujube.

[0042] When the lifting plate 56 moves upward in its initial state, it presses against the bottom of the top-moving frame 73. Since the elastic force of the second spring 9 is greater than that of the elastic bladder 71, the top-moving frame 73 moves upward with the push plate 72. This allows the medium inside the frame 51 to enter the interior of the first flexible tube 74, the mounting block 52, and the connecting tube 53, and then enter the interior of the elastic bladder 71. This allows the elastic bladder 71 to expand and clamp the jujubes, ensuring a clamping effect. After the elastic bladder 71 expands, it will push the jujubes towards the middle position of the clamping frame 55, ensuring that the middle position of the jujubes is located in the middle position of the clamping frame 55, further reducing the occurrence of pitting deviation.

[0043] When pitting is required, the output shaft of the electric telescopic rod 31 extends, causing the horizontal plate 32 to move forward along with the pitting punch 33. Just as the pitting punch 33 is about to contact the jujube, the horizontal plate 32 contacts the end of the moving frame 812. As the output shaft of the electric telescopic rod 31 continues to extend, the moving frame 812 is compressed, causing the third piston 86 to move forward. During this process, the medium inside the long groove 810 enters the second flexible tube 814, and then the medium enters the sleeve 85. This causes the third piston 86 to move forward along with the round shaft 87, overcoming the elastic force of the third spring 813. At this time, the mounting plate 88 is moved forward... As the protrusions 89 move forward, when one of the protrusions 89 limits the swing rod 84, it can squeeze the swing rod 84, causing the swing rod 84 to deflect along with the small plate 83. This causes the collar 82 to rotate outside the connecting pipe 53, and the long strip 81 to rotate along with the mounting pipe frame 54. This causes the clamping frame 55 to rotate along with the clamped jujube. During the pitting process, the jujube can be continuously rotated in small amplitudes. The impact force will be gradually dispersed to different parts of the fruit pulp with the swing, rather than concentrated at one point, avoiding local stress concentration. The fruit pulp integrity rate can be increased to a higher level, greatly reducing raw material waste and further improving the pitting effect of jujubes.
