Description

Technical Field

[0001] The invention belongs to the technical field of betel nut processing devices, and specifically 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 feeding and traying machine has the following problems: The existing betel nut loading and traying device places the betel nuts into the tray one by one, and has a low degree of automation. Some betel nut loading and traying machines directly pour the betel nuts into the tray and use shaking to put the betel nuts back in place. It is impossible to deal with the debris generated during the shaking process, and it is difficult to screen the betel nuts by size. In addition, it is difficult to detect and correct the betel nuts with the fruit cavity opening facing downward or offset, and the production efficiency is low. Summary of the invention

[0004] In order to solve the above-mentioned existing problems, the present invention provides an automatic betel nut 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 process of betel nuts continuous and automated, thereby improving production efficiency.

[0005] 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, a position-adjusting type 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 position-adjusting type loading component is arranged above the conveying mechanism, and the scraping and sweeping type screening mechanism is arranged at the position-adjusting type loading component. The upper part of the position-adjustable feeding assembly is provided with a feeding box; the position-adjustable feeding assembly comprises a connecting plate, a limiting bar and a toggle mechanism, the connecting plate is connected to the inner side of the operating table, the limiting bar is tilted and evenly distributed on the side wall of the connecting plate away from the upper plate mechanism, the limiting bar is arranged in a triangular prism shape, one edge of which faces upward, 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 bars is smaller than the upper opening of the betel nut, one side of the most side limiting bar is connected with a sliding plate, and the toggle mechanism is arranged below the limiting bar; Furthermore, the scraping and sieving mechanism includes a support plate, a power rotating column, a connecting belt, and a magnetic-driven scraping mechanism. The support plates are symmetrically arranged on the outer side walls of the operating table and are parallel to the upper side of the limit strip rods. The power rotating columns are symmetrically and rotatably arranged on the support plates on the side away from the sliding plate, and the power rotating columns are driven by scraping motors. A first tensioning column is rotatably arranged between the symmetric power rotating columns. On the other side of the support plates, second tensioning columns are symmetrically and rotatably arranged. The connecting belt is wound in a meandering snake shape between the power rotating columns, the first tensioning column, and the second tensioning columns, and the two ends of the connecting belt are respectively wound around the symmetric power rotating columns. The magnetic-driven scraping mechanisms are evenly distributed on the connecting belt, and there are four groups of magnetic-driven scraping mechanisms. When one side of the power rotating column rotates to wind up the connecting belt, the first group of magnetic-driven scraping mechanisms moves towards the power rotating column that winds up the belt, the second group of magnetic-driven scraping mechanisms moves towards the second tensioning column on the same side, the third group of magnetic-driven scraping mechanisms moves towards the first tensioning column, and the fourth group of magnetic-driven scraping mechanisms moves towards the second tensioning column on the other side (it is stipulated that the magnetic-driven scraping mechanism closest to the feeding box is the fourth group, and so on in sequence). The magnetic-driven scraping mechanisms slide on the upper part of the limit strip rods.

[0006] Furthermore, the swing plate detection assembly includes a swing table and a detection pressing plate.

The outer edges of the flipping push blocks are arc-shaped. During detection, the detection pressing plate is pressed down into the material tray, and the detection probes can extend into the openings of the betel nuts. If the opening positions of the betel nuts are offset, the edges of the betel nuts will squeeze the detection probes, and the springs will be compressed. At this time, the electric telescopic rod on one side is activated, and the flipping push block is pushed out to squeeze the edge of the betel nut, causing the betel nut to flip. If the detection probe still cannot pop out after the flipping push block on this side is pushed to the end, the electric telescopic rod on the other side is activated, and the flipping push block squeezes the other edge of the betel nut, causing the betel nut to flip in the opposite direction until the detection probe pops out, ensuring that the openings of the betel nuts are uniformly facing upwards, which is convenient for the subsequent brine-pointing process.

[0007] Preferably, the feeding box is arranged on the connecting plate and is set on the side away from the sliding plate. A feeding roller is rotatably arranged at the lower opening of the feeding box. The feeding roller is arranged above the limit strip rods and is driven by a feeding motor. Distribution plates are evenly arranged on the outer circumference of the feeding roller. A fixed quantity of betel nuts can be transported between adjacent distribution plates, which is convenient for the batch-by-batch transportation of betel nuts and avoids betel nuts from gathering in a pile. Furthermore, the toggle mechanism includes a toggle roller, a toggle belt and a toggle plate. The toggle roller is symmetrically rotatable and arranged below the limit bar. 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. The toggle belt is wrapped around the toggle roller. Partitions are evenly distributed on the toggle belt. 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 partition. A toggle spring is connected between the toggle plate and the partition. The toggle plate can only rotate in the opposite direction of the movement of the toggle belt.

For the betel nut with larger specifications that cannot fall between the limit bars, it is directly scraped into the sliding plate. When the magnetic scraping mechanism runs to the top of the sliding plate, the convex rod on the inner wall of the operating table pushes against the trigger button, 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 absorbs the magnetic block, and the scraping plate moves up, the positioning rod and the sliding rod 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, and 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 that is not scraped in time. The betel nuts on the slide plate are swept back again, and 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 rotating column rotates in the opposite direction again, in this cycle, the magnetic scraping mechanism scrapes cyclically on the upper part of the limit bar, scatters the stacked betel nuts and pushes them between the limit bars, and sweeps the larger betel nuts onto the slide plate, while 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, and the larger betel nuts roll from the slide plate to the collection trough for recovery, and the semi-oblate betel nuts are narrow at both ends.

The tray 10 slides onto the conveyor belt 43 and is conveyed by the conveyor belt 43. The tray push rod 9 contracts, and the upper tray push plate 11 resets. The upper tray 10 drops, and the upper tray push plate 11 waits to push the next tray 10, realizing cyclic feeding. When the tray 10 is conveyed by the conveyor belt 43 above the conveying plate 45, the main power roller 41 stops working, the electric push column extends, pushing the conveying plate 45 to lift up the tray 10 and lift the tray 10 to the lower part of the transition plate 15. At the same time, the moving push rod 46 slowly extends, and the conveying plate 45 carries the tray 10 and slowly slides at the lower end of the transition plate 15.

[0027] While the material tray 10 is being transported, the feeding motor 21 works, the feeding roller 20 rotates, and the betel nuts in the feeding box 5 are transported to the limiting bars 13 in batches. The toggle motor is started, and the toggle motor drives the toggle roller 24 to rotate, so that the toggle belt 25 drives the partition plate 26 to move, and the toggle plate 27 moves in the gap between the limiting bars 13, and the betel nuts that fall on the limiting bars 13 are pushed away and transported to the transition plate 15.At the same time, the scraping motor on the side away from the feed box 5 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 feed box 5 is 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 reeling 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 the 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 to the top of the slide plate 14, the convex rod on the inner wall of the operating table 1 is pushed onto 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 to move the scraping plate 37 upward, and the positioning rod 38 and the slide bar 40 slide upward in the conversion block 36. At this time, one side of the line is released The power column 30 rotates in the opposite direction to reel in the connecting belt 34, and the four groups of magnetic scraping mechanisms 35 all move in the opposite direction, and the second and fourth groups of magnetic scraping mechanisms 35 above the sliding plate 14 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 limiting bar 13 to avoid the betel nut on the limiting bar 13 that has not been scraped into the sliding 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, and the cycle is repeated. The structure 35 scrapes and sweeps cyclically on the upper part of the limiting bars 13, scatters the stacked betel nuts and pushes them between the limiting bars 13, and sweeps the larger betel nuts onto the sliding plate 14, while 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 driving belt 25 rotates, and the larger betel nuts roll from the sliding plate 14 to the collection trough 47 for recovery. The semi-oblate betel nuts are narrow at both ends, and under the guidance and restriction of the limiting bars 13, the betel nuts are adjusted in position during transportation, and their narrow ends are uniformly oriented toward the transportation direction, and the technical effect of screening the specifications of the betel nuts is also achieved, ensuring that the shape of the finished betel nuts is uniform; The toggle plate 27 pushes the betel nut to the lower end of the limit bar 13. During the process of the betel nut falling onto the transition plate 15, it touches the counting plate 18. The counting plate 18 is suspended. Each 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 greater inclination and falls into the material tray 10. During the slow movement of the material tray 10, the betel nuts are evenly spread in the material tray 10, and the narrow end orientation of the betel nuts is the same as that of the narrow end of the groove in the material tray 10. When the count of the counter 19 reaches the number of grooves in the material tray 10, that is, when the number of betel nuts is the same as the number of grooves in the material tray 10, the toggle roller 24 stops rotating and no longer conveys betel nuts to the transition plate 15.

[0028] Subsequently, the electric push post contracts, and the transport plate 45 carries the material tray 10 downwards, placing the material tray 10 filled with betel nuts on the conveyor belt 43. The moving push rod 46 contracts, and the transport plate 45 resets. At the same time, the push plate push rod 9 starts, pushing the next material tray 10 onto the conveyor belt 43. The main driving roller 41 starts, and 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 above the reset transport plate 45. The transport plate 45 repeats the process of supporting the empty material tray 10 to move upwards and receiving betel nuts. The toggle roller 24 starts again to push the betel nuts onto the transition plate 15 for feeding the next material tray 10. The transfer push rod 50 extends, enabling the transfer plate 49 to carry the material tray 10 on the receiving plate 44. At the same time, the transfer screw 48 rotates, causing the transfer push rod 50 to drive the transfer plate 49 and the material tray 10 to move towards the shaking table 51. When the material tray 10 moves directly below the detection pressure plate 56, the symmetric clamping plates 52 clamp both sides of the material tray 10. At this time, the motor starts, and the shaking block 53 rotates and pushes the symmetric 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 nuts inside it to roll left and right under the action of inertia. When the narrow end of the betel nut faces down and the opening faces up and falls into the groove, it is difficult to be shaken out again. After the shaking block 53 operates for a period of time and resets, then the hydraulic push column 55 starts, and the detection pressure plate 56 presses down into the material tray 10. The detection probe 57 corresponds to the position of the groove in the material tray 10. The detection probe 57 can extend 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 compresses. At this time, the electric telescopic rod on one side starts, and the flipping block 58 is pushed out to squeeze the edge of the betel nut, causing the betel nut to flip in the arc-shaped groove. If the detection probe 57 still cannot pop out after the flipping block 58 on this side is pushed to the end, then the electric telescopic rod on the other side starts, and the flipping block 58 on the other side squeezes the other edge of the betel nut, causing the betel nut to flip in the opposite direction until the detection probe 57 pops out, ensuring that the openings of the betel nuts are uniformly facing up, facilitating the subsequent process of dotting the sauce.

[0029] After the betel nut opening positions are unified, the transfer screw rod 48 rotates, causing the transfer plate 49 to drive the tray 10 filled with betel nuts to move to the discharge push plate 59. Subsequently, the telescopic motor is started, and the discharge push plate 59 pushes the tray 10 onto the conveyor belt 43 of the next process. Finally, the transfer screw rod 48 is started again to reset the transfer push rod 50, and the transfer plate 49 then transfers the next tray 10.
