Description

Technical Field

[0001] The invention belongs to the technical field of betel nut processing devices, and particularly relates to an automatic betel nut loading and traying machine. Background Art

[0002] The fruit of betel nut is oblong or ovoid. During the production process of betel nut food, the betel nut is split in half and the core is removed. After seasoning and drying and shaping, the betel nut needs to be loaded onto a plate with the opening of the betel nut cavity facing upwards to facilitate subsequent processes such as braising.

[0003] The existing betel nut automatic loading and traying machine has the following problems:

[0004] Existing betel nut loading and traying devices place betel nuts into the tray one by one, with a low degree of automation. Some betel nut loading and traying machines pour the betel nuts directly into the tray and use shaking to return them to their original positions. This makes it impossible to process the debris generated during the shaking process, and it is also difficult to screen the betel nuts by size. In addition, it is difficult to detect and correct betel nuts with downward or offset fruit cavity openings, resulting in low production efficiency. Summary of the Invention

[0005] In order to solve the above-mentioned existing problems, the present invention provides a betel nut automatic loading and traying machine that can adjust the conveying angle of betel nuts in batches, screen the specifications of betel nuts in advance, and timely detect and correct the direction of the fruit cavity opening. It adopts the pre-action principle to make the production and manufacturing process of betel nuts continuous and automated, thereby improving production efficiency.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: the present invention provides an automatic betel nut loading and traying machine, comprising an operating table, one end of the operating table is provided with a tray loading mechanism, the other end of the operating table is connected to a swing plate detection component, the inner side of the operating table is respectively provided with a conveying mechanism, an adjustable loading component and a scraping and sweeping type screening mechanism, the conveying mechanism is arranged between the tray loading mechanism and the swing plate detection component, the adjustable loading component is arranged above the conveying mechanism, and the scraping and sweeping type screening mechanism is arranged on the upper side of the adjustable loading component. Above, a feed box is provided on the upper part of the position-adjustable loading assembly; the position-adjustable loading assembly includes a connecting plate, a limiting rod and a toggle mechanism, the connecting plate is connected to the inner side of the operating table, the limiting rods are tilted and evenly distributed on the side wall of the connecting plate away from the upper disk mechanism, the limiting rods are arranged in a triangular prism shape, one edge of which faces upward, and the shape of the betel nut to be processed is a semi-oblate sphere with a narrow bottom and a wide top. The spacing between the limiting rods is smaller than the upper opening of the betel nut, and a sliding plate is connected to one side of the most side limiting rod, and the toggle mechanism is arranged below the limiting rod;

[0007] Furthermore, the scraping and sweeping screening mechanism includes a support plate, a power rotating column, a connecting belt and a magnetic scraping and sweeping mechanism, the support plate is symmetrically arranged on the outer wall of the operating table, the support plate is parallel to the upper part of the limit bar, the power rotating column is symmetrically rotated on the support plate on the side away from the sliding plate, the power rotating column is driven by the scraping motor, a first tensioning column is rotated between the symmetrical power rotating columns, and a second tensioning column is symmetrically rotated on the support plate on the other side, the connecting belt is winding and connected between the power rotating column, the first tensioning column and the second tensioning column, and the connecting belt is The two ends are respectively wound around the symmetrical power rotating column, and the magnetic scraping mechanism is arranged on the connecting belt. There are four groups of magnetic scraping mechanisms. When the power rotating column on one side rotates to reel up the connecting belt, the first group of magnetic scraping mechanisms moves toward the reeled power rotating column, the second group of magnetic scraping mechanisms moves toward the second tensioning column on the same side, the third group of magnetic scraping mechanisms moves toward the first tensioning column, and the fourth group of magnetic scraping mechanisms moves toward the second tensioning column on the other side (the magnetic scraping mechanism closest to the feed box is specified as the fourth group, and so on). The magnetic scraping mechanism slides on the upper part of the limit bar.

[0008] Furthermore, the wobble plate detection assembly includes a shaking table and a detection pressure plate, the shaking table is symmetrically connected to one end of the operating table away from the upper plate mechanism, the symmetrical shaking table is connected to a detection frame, the detection frame is provided with a hydraulic push column, the detection pressure plate is horizontally arranged at the output end of the hydraulic push column, the lower wall of the detection pressure plate is embedded with sliding detection probes uniformly distributed, a spring is provided between the detection probe and the detection pressure plate, flip push blocks are symmetrically provided on both sides of the detection probe, the flip push blocks are slidably arranged in the detection pressure plate, the flip push blocks are driven by an electric telescopic rod, and the outer edge of the flip push block is arc-shaped;

[0009] During testing, the testing pressure plate is pressed down into the material tray, and the testing probe can be extended into the opening of the betel nut. If the opening position of the betel nut is offset, the edge of the betel nut will squeeze the testing probe and the spring will be compressed. At this time, the electric telescopic rod on one side is started, and the flip push block is pushed out to squeeze the edge of the betel nut and turn the betel nut over. If the testing probe still cannot pop out after the flip push block on that side is pushed to the bottom, the electric telescopic rod on the other side is started, and the flip push block squeezes the edge of the other side of the betel nut, causing the betel nut to flip in the opposite direction until the testing probe pops out, ensuring that the opening of the betel nut is uniformly facing upward, which is convenient for the subsequent braising process.

[0010] Preferably, the feed box is arranged on the connecting plate, and the feed box is arranged on a side away from the sliding plate. A feeding roller is rotatably provided at the lower opening of the feed box, and the feeding roller is arranged above the limiting bar. The feeding roller is driven by a feeding motor; the outer circumference of the feeding roller is evenly distributed with dividing plates, and a certain amount of betel nuts can be transferred between adjacent dividing plates, which is convenient for the batch transportation of betel nuts and avoids the betel nuts from clumping.

[0011] Furthermore, the toggle mechanism includes a toggle roller, a toggle belt and a toggle plate. The toggle roller is symmetrically arranged below the limit bar, and the plane where the central axis of the symmetrical toggle roller is located is parallel to the lower wall of the limit bar. The toggle roller is driven by a toggle motor, and the toggle belt is wrapped around the toggle roller. Partitions are evenly distributed on the toggle belt, and the partitions are perpendicular to the surface of the toggle belt. The linear array of toggle plates is evenly distributed on the partitions. The toggle plate is rotatably connected to the partitions, and a torsion spring is connected between the toggle plate and the partitions. The toggle plate can only rotate in the opposite direction of the movement of the toggle belt, and the toggle plate slides between adjacent limit bars.

[0012] Preferably, the lower part of one end of the limiting bar away from the connecting plate is obliquely connected to a transition plate, the inclination angle of the transition plate is greater than the inclination angle of the limiting bar, a material collection trough is provided on the inner side wall of the operating table, the sliding plate is connected to the material collection trough, the lower part of the transition plate is connected to a collecting plate, a collecting basket is slidably provided on the collecting plate, the collecting basket is provided below the toggle mechanism, and the collecting basket can be pulled out;

[0013] Furthermore, a connecting rod is provided on the upper part of one end of the limit bar away from the connecting plate, and counting plates are evenly distributed on the lower part of the connecting rod. The counting plates are suspended between the limit bars, and a counter is provided on the upper part of the connecting rod. The counter and the counting plates are electrically connected in series.

[0014] Furthermore, the magnetic scraping mechanism includes a conversion block, a slide rod, a magnetic block and a scraping plate, the conversion block is connected to the lower wall of the connecting belt, the slide rod passes through and slides in the center of the conversion block, the slide rod passes through the connecting belt, the scraping plate is provided at the lower end of the slide rod, the magnetic block is sleeved on the slide rod, the magnetic block is provided on the upper part of the scraping plate, the lower part of the conversion block is embedded with an electromagnetic block, the electromagnetic block and the magnetic block are correspondingly arranged, the upper part of the scraping plate is symmetrically provided with positioning rods, the positioning rods pass through and slide on both sides of the conversion block, the scraping plate is arc-shaped toward the side wall of the sliding plate, and a trigger button is provided on the conversion block;

[0015] When in use, when the magnetic scraping mechanism moves toward the sliding plate, during the movement, the scraping plate slides on the upper part of the limit bar, and the scraped betel nut falls between the limit bars. For the betel nut with a larger size that cannot fall between the limit bars, it is directly scraped into the sliding plate. When the magnetic scraping mechanism runs above the sliding plate, the convex rod on the inner wall of the operating table hits the trigger button, and the electromagnetic block is energized to generate magnetism. The magnetic pole of the electromagnetic block is different from the magnetic pole of the magnetic block. The electromagnetic block attracts the magnetic block, causing the scraping plate to move up, and the positioning rod and the slide bar slide up in the conversion block. At this time, the power column on the line-releasing side rotates in the opposite direction to reel in the connecting belt. The four sets of magnetic scraping mechanisms all move in the opposite direction, and the magnetic scraping mechanism running to the top of the sliding plate moves toward the first tensioning column. Because the electromagnetic block and the magnetic block are adsorbed together, during the movement, the scraping plate is away from the limit bar to avoid the limit bar being unable to be scraped in time. The betel nuts on the slide plate are swept back again. When the conversion block moves back to the side of the first tensioning column, the trigger button on that side is squeezed, the electromagnetic block is powered off and demagnetized, and under the action of gravity, the scraping plate falls down, and the power column rotates in the opposite direction again. In this cycle, the magnetic scraping mechanism scrapes cyclically on the upper part of the limit bar, spreading the stacked betel nuts and pushing them between the limit bars, while sweeping the larger betel nuts onto the slide plate. The debris or smaller betel nuts generated during the betel nut transportation process fall between the partitions through the gaps between the limit bars, and fall into the collection basket as the toggle belt rotates. The larger betel nuts roll from the slide plate to the collection trough for recovery. The semi-oblate betel nuts are narrow at both ends. Under the guidance and restriction of the limit bar, the betel nuts adjust their position during transportation, and their narrow ends are uniformly facing the transportation direction. At the same time, the technical effect of screening the specifications of the betel nuts is achieved, ensuring that the finished betel nuts are uniform in shape.

The pushing disk push rod retracts, the upper disk push plate resets, the upper material tray falls, and the upper disk push plate waits to push the next material tray to realize cyclic loading.

[0020] The beneficial effects achieved by the present invention using the above structure are as follows:

[0021] 1. The present invention provides an automatic betel nut loading and traying machine, which adopts the pre-action principle combined with the electromagnetic principle. Under the joint action of the triangular prism-shaped limiting bars, the scraping and sweeping screening mechanism that circulates reciprocatingly, and the electromagnetically controlled magnetic scraping and sweeping mechanism, combined with the semi-oblate spherical morphological characteristics of the betel nuts, the stacked betel nuts are spread out and pushed between the limiting bars, while the larger betel nuts are swept onto the sliding plate.

[0022] 2. A tray detection component is set up to determine the position of the betel nut cavity opening by extending and retracting the detection probe. The betel nut's morphological characteristics are used to press the flip push block to cause it to flip in the arc-shaped groove until the detection probe enters the betel nut opening. After the betel nuts are placed on the tray, the direction of the cavity opening is promptly detected and corrected to ensure that the opening of the betel nuts is uniformly facing upward, facilitating the subsequent braising process.

[0023] 3. The upper plate mechanism realizes the circulation of the upper plate, the conveying mechanism realizes the transfer of the material plate and the flat loading of the betel nut, the clamping plate and the shaking block realize the positioning of the betel nut on the plate, and the transfer screw and transfer plate realize the continuous transfer and unloading of the betel nut material plate, making the production process of betel nut continuous and automated, and improving production efficiency.

[0050] When in use, the conveyor belt of the next process of the production line is connected to the shaking table 51 away from the side of the discharge push plate 59, the material tray 10 is stacked and placed on the upper tray table 8, the betel nut to be processed is poured into the material box 5, the main controller is started, the main power motor is started, the main power roller 41 rotates, and the conveyor belt 43 runs. At the same time, the push plate push rod 9 is started, and the upper tray push plate 11 pushes the bottom material tray 10 to slide out from the tray outlet. The material tray 10 slides to the conveyor belt 43 and is transported by the conveyor belt 43. The push plate push rod 9 contracts, the upper plate push plate 11 resets, the upper material tray 10 falls, and the upper plate push plate 11 waits to push the next material tray 10 to realize cyclic loading; when the material tray 10 is transported to the top of the transport plate 45 by the conveyor belt 43, the main power roller 41 stops working, the electric push column extends, pushing the transport plate 45 to move up and lift the material tray 10, and lift the material tray 10 to the lower part of the transition plate 15. At the same time, the moving push rod 46 slowly extends, and the transport plate 45 carrying the material tray 10 slowly slides on the lower end of the transition plate 15.

[0051] While the tray 10 is being transported, the feeding motor 21 is working, the feeding roller 20 is rotating, and the betel nuts in the feed box 5 are transferred to the limiting bars 13 in batches. The toggle motor is started, and the toggle motor drives the toggle roller 24 to rotate, thereby causing the toggle belt 25 to drive the partition 26 to move. The toggle plate 27 moves in the gap between the limiting bars 13, to push away the betel nuts that have fallen on the limiting bars 13 and toggle them for transportation to the transition plate 15.At the same time, the scraping motor away from the feeding box 5 side drives its corresponding power column 30 to rotate, and the power column 30 rotates to reel in the connecting belt 34, and the power column 30 on the other side rotates to release the connecting belt 34, and the first tensioning column 31 and the second tensioning column 32 follow the rotation, and driven by the connecting belt 34, the fourth group of magnetic scraping mechanisms 35 moves toward the second tensioning column 32 on the same side (the magnetic scraping mechanism 35 closest to the feeding box 5 side is specified as the fourth group, and so on), the third group of magnetic scraping mechanisms 35 moves toward the first tensioning column 31, the second group of magnetic scraping mechanisms 35 moves toward the second tensioning column 32 on the other side, and the first group of magnetic scraping mechanisms 35 moves toward the winding power column. 30 moves, that is, the fourth group and the second group of magnetic scraping mechanisms 35 move toward the slide plate 14. During the movement, the scraping plate 37 slides on the upper part of the limit bar 13, scraping the betel nuts and falling between the limit bars 13. For betel nuts with larger specifications that cannot fall between the limit bars 13, they are directly scraped into the slide plate 14. When the magnetic scraping mechanism 35 runs above the slide plate 14, the protruding rod on the inner wall of the operating table 1 is pressed against the trigger button, and the electromagnetic block 39 is energized to generate magnetism. The magnetic pole of the electromagnetic block 39 is different from the magnetic pole of the magnetic block 39. The electromagnetic block 39 attracts the magnetic block 39, causing the scraping plate 37 to move up, and the positioning rod 38 and the slide bar 40 slide up in the conversion block 36. At this time, the pay-off side The power column 30 rotates in the opposite direction to reel in the connecting belt 34. The four sets of magnetic scraping mechanisms 35 all move in the opposite direction and run to the second and fourth sets of magnetic scraping mechanisms 35 above the slide plate 14 and move toward the first tensioning column 31. Since the electromagnetic block 39 is adsorbed together with the magnetic block 39, during the movement, the scraping plate 37 is away from the limit bar 13 to avoid the betel nut on the limit bar 13 that has not been scraped into the slide plate 14 in time being swept back. When the conversion block 36 moves back to the side of the first tensioning column 31, the trigger button on that side is squeezed, the electromagnetic block 39 is powered off and demagnetized, and under the action of gravity, the scraping plate 37 falls, and the power column 30 rotates in the opposite direction again. In this cycle, the magnetic scraping mechanism The structure 35 scrapes and sweeps cyclically on the upper part of the limiting bars 13, spreading the stacked betel nuts and pushing them between the limiting bars 13, while sweeping the larger betel nuts onto the sliding plate 14. The debris or smaller betel nuts generated during the betel nut transportation process fall between the partitions 26 through the gaps between the limiting bars 13 and fall into the collection basket 23 as the paddle belt 25 rotates. The larger betel nuts roll from the sliding plate 14 to the collecting trough 47 for recovery. The semi-oblate spherical betel nuts are narrow at both ends. Under the guidance and restriction of the limiting bars 13, the betel nuts are adjusted in position during transportation, with their narrow ends uniformly facing the transportation direction. At the same time, the technical effect of screening the specifications of the betel nuts is achieved, ensuring that the finished betel nuts have a uniform shape.

[0052] The toggle plate 27 pushes the betel nut to the lower end of the limit bar 13. The betel nut touches the counting plate 18 in the process of falling to the transition plate 15. The counting plate 18 is suspended. Every time a betel nut touches the counting plate 18, the counter 19 counts once. The betel nut slides down from the transition plate 15 with a larger inclination and falls into the material tray 10. During the slow movement of the material tray 10, the betel nut is evenly spread in the material tray 10, and the narrow end of the betel nut is facing the same direction as the narrow end of the groove of the material tray 10. When the count of the counter 19 reaches the number of grooves of the material tray 10, that is, the number of betel nuts is the same as the number of grooves of the material tray 10, the toggle roller 24 stops rotating and no longer transports betel nuts to the transition plate 15.

[0053] Then the electric push column retracts, the transport plate 45 carries the material tray 10 and moves down, and the material tray 10 filled with betel nuts is placed on the conveyor belt 43, the moving push rod 46 retracts, the transport plate 45 resets, and at the same time the push plate push rod 9 starts to push the next material tray 10 onto the conveyor belt 43, the main power roller 41 starts, the conveyor belt 43 transports the material tray 10 filled with betel nuts to the receiving plate 44, and transports the next empty material tray 10 to the top of the reset transport plate 45, the transport plate 45 repeats the support of the empty material tray 10 to move up and receive the betel nuts, the stirring roller 24 starts again to push the betel nuts to the transition plate 15, and the next material tray 10 is loaded;

[0054] The transfer push rod 50 is extended, so that the transfer plate 49 carries the material tray 10 on the receiving plate 44, and at the same time the transfer screw 48 rotates, so that the transfer push rod 50 drives the transfer plate 49 and the material tray 10 to move toward the shaking table 51. When the material tray 10 moves to just below the detection pressure plate 56, the symmetrical clamping plates 52 clamp the two sides of the material tray 10. At this time, the motor starts, the shaking block 53 rotates, and pushes the symmetrical clamping plates 52 to drive the material tray 10 to slide left and right on the transfer plate 49. The shaking material tray 10 causes the betel nut inside to roll left and right under the action of inertia. When the narrow end of the betel nut falls into the groove with the opening facing downward and upward, it is difficult to be shaken out. The shaking block 53 resets after running for a period of time, and then the hydraulic push column 55 starts The detection pressure plate 56 is pressed down into the material tray 10, and the position of the detection probe 57 corresponds to the position of the groove of the material tray 10. The detection probe 57 can be inserted into the opening of the betel nut. If the opening position of the betel nut is offset, the edge of the betel nut will squeeze the detection probe 57, and the spring is compressed. At this time, the electric telescopic rod on one side is started, and the flip push block 58 is pushed out to squeeze the edge of the betel nut, so that the betel nut flips in the arc-shaped groove. If the detection probe 57 still cannot pop out after the flip push block 58 on this side is pushed to the bottom, the electric telescopic rod on the other side is started, and the flip push block 58 on the other side squeezes the edge of the other side of the betel nut, causing the betel nut to flip in the opposite direction until the detection probe 57 pops out, ensuring that the opening of the betel nut is uniformly facing upward, which is convenient for the subsequent braising process.

[0055] After unifying the opening position of the betel nuts, the transfer screw 48 rotates, causing the transfer plate 49 to drive the material tray 10 filled with betel nuts to move to the discharge push plate 59, and then the telescopic motor is started, and the discharge push plate 59 pushes the material tray 10 to the conveyor belt 43 of the next process. Finally, the transfer screw 48 is started again to reset the transfer push rod 50, and the transfer plate 49 then transfers the next material tray 10.

[0056] It is worth noting that the program programming application of the logic control module and the timing control module of the main controller is an existing technology and will not be described in detail here.
