Description

Technical Field

[0001] This invention relates to a nut packaging device, specifically a macadamia nut packaging machine and its usage method. Background Technology

[0002] Currently, the processing flow for macadamia nuts is as follows: nuts with clips → nut removal → grading of nuts with shells → drying of nuts with shells → storage → shell breaking → kernel grading → packaging.

[0003] Macadamia nuts can be produced as kernels or shelled nuts. Therefore, when obtaining shelled kernels, there is no need for subsequent production processes such as "shelling".

[0004] However, the inventors discovered that neither the kernel packaging nor the shelled kernel packaging involved a second sterilization of the macadamia nuts before packaging. Especially in southern regions with high humidity, macadamia nuts are susceptible to mold infection. Therefore, to address the shortcomings of existing technology, a macadamia nut packaging machine was developed to sterilize macadamia nuts before packaging. Summary of the Invention

Detailed Implementation

[0042] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments in this application. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0043] like Figure 1-10 As shown, a macadamia nut packaging machine includes an ultraviolet (UV) sterilization mechanism, a feeding conveyor 8, a diverter 6, a kernel elevator 7, a kernel packaging mechanism 9, a shell elevator 10, and a shell packaging mechanism. The UV sterilization mechanism performs UV sterilization. The feeding conveyor is connected to the UV sterilization mechanism and supplies macadamia nuts to it. The diverter 6 receives macadamia nuts discharged from the UV sterilization mechanism and includes a kernel diverter end and a shell diverter end. The kernel elevator 7 is connected to the kernel diverter end 62. The kernel packaging mechanism 9 is connected to the kernel elevator 7 and is used to package the kernels. The shell elevator is connected to the shell diverter end 61. The shell packaging mechanism is connected to the shell elevator and is used to package shelled kernels. Wherein, if the UV sterilization mechanism discharges kernels, the kernel diverter end is connected to the kernel elevator; if the UV sterilization mechanism discharges shelled kernels, the shell diverter end is connected to the shell elevator.

[0044] like Figure 1As shown, the ultraviolet sterilization mechanism includes an ultraviolet sterilization furnace 2, a sterilization feeding conveyor 4, a support frame 1, and a baffle 3. The sterilization feeding conveyor 4 is installed on top of the support frame 1, and the ultraviolet sterilization furnace 2 is mounted on the sterilization feeding conveyor 4. The sterilization feeding conveyor 4 is used to transport macadamia nuts for sterilization in the ultraviolet sterilization furnace 2. A baffle 3 is installed at the inlet end of the ultraviolet sterilization furnace 2, and the baffle 3 is installed on top of the sterilization feeding conveyor 4 to prevent macadamia nuts conveyed by the feeding conveyor 8 from rolling out of the sterilization feeding conveyor 4.

[0045] It should be noted that the ultraviolet sterilization furnace 2 includes an ultraviolet sterilization chamber. The ultraviolet sterilization chamber has a sterilization tunnel, with multiple ultraviolet sterilization lamps installed on the sides and top of the tunnel. An inlet and an outlet are respectively located on two corresponding end faces of the tunnel. The ultraviolet sterilization chamber is mounted on top of the feeding conveyor. A enclosure 3 is installed near the inlet of the tunnel on top of the feeding conveyor and is used to store macadamia nuts. The feeding conveyor transports the macadamia nuts falling from the hopper through the inlet, sterilization tunnel, and outlet of the tunnel for sterilization.

[0046] It should also be noted that the feeding conveyor moves the macadamia nuts from the inlet to the outlet of the sterilization tunnel, thus completing the sterilization process. Understandably, the feeding conveyor can be set to a suitable speed according to the sterilization requirements, ensuring that the macadamia nuts travel within the sterilization tunnel for the desired sterilization time. For example, if the set time from the inlet to the outlet is 30 to 300 seconds, the speed of the feeding conveyor can be adjusted to ensure that the travel time of the macadamia nuts within the sterilization tunnel matches the set sterilization time.

[0047] Understandably, such as Figure 1 As shown, the sterilization feeding conveyor sequentially passes through the tunnel entrance, sterilization tunnel, and tunnel exit. As the sterilization feeding conveyor operates, macadamia nuts falling from the enclosure onto it are carried into the sterilization tunnel for ultraviolet sterilization.

[0048] like Figure 1 The aforementioned enclosure 3 is used to enclose one end of the sterilization feeding conveyor located on the side of the tunnel entrance, which can prevent the macadamia nuts in the waiting bin from rolling off the conveyor belt and allowing the conveyor belt to effectively transport the macadamia nuts in the waiting bin into the sterilization tunnel for sterilization.

[0049] To ensure a flat layer of macadamia nuts on the top surface of the sterilization conveyor entering the sterilization tunnel, the distance between the tunnel entrance and the top surface of the conveyor belt on the sterilization conveyor is slightly larger than the diameter of the macadamia nuts. When the sterilization conveyor operates, it carries the macadamia nuts from the enclosure into the sterilization tunnel. The obstruction at the end of the ultraviolet sterilization chamber and the height restriction at the tunnel entrance ensure that the macadamia nuts carried into the sterilization tunnel are laid flat on the top surface of the sterilization conveyor, preventing them from overlapping. Multiple ultraviolet sterilization lamps are installed on the sides and top of the sterilization tunnel to effectively sterilize the macadamia nuts entering the tunnel.

[0050] The wavelength of ultraviolet germicidal lamps ranges from 10 to 400 nm. The appropriate wavelength can be selected based on production needs.

[0051] In some alternative embodiments, one structure of the nut packaging mechanism is provided. For example... Figure 2 As shown, the nut packaging mechanism 9 includes a nut frame 91, a nut packaging bag roller 92, a guide cylinder 919, a guide funnel 917, a shrinking part 918, a shaping part 924, a hot melt welding part 920, a pulling roller group 921, a heat sealing and cutting part 922, and a positioning sensor 923.

[0052] The nut packaging bag roller 92 is rotatably mounted on one end of the nut machine frame 91. The other end of the nut machine frame 91 is equipped with, from top to bottom, a guide funnel 917, a winding component 918, a shaping component 924, a hot-melt welded component 920, a traction roller assembly 921, and a heat-sealing and cutting component 922. One end of the guide cylinder 919 is connected to the guide funnel 917, and the other end passes through the shaping component 924. A positioning sensor 923 is arranged parallel to the traction roller assembly 921. A blocking plate 914 is installed on the top of the guide funnel 917. Multiple discharge holes are distributed around the bottom circumference of the packaging cylinder 911. A metering cylinder 913 is installed at the bottom of each discharge hole, and the bottom of the metering cylinder 913 is attached to the blocking plate. Plate 914; partition plate 910 is installed inside packaging cylinder 911 to guide the nuts inside packaging cylinder 911 into the discharge hole; guide plate 97 is installed on the top of packaging cylinder 911; nut discharge hopper 96 is installed on the top of guide plate 97; one end of sleeve 915 is connected to nut machine frame 91, and the other end is connected to block plate 914; one end of rotating shaft 916 passes through sleeve 915 and is connected to packaging cylinder 911 for transmission, and the other end is rotatably connected to nut machine frame 91; nut packaging motor 94 is installed on nut machine frame 91 and is connected to rotating shaft 916 for transmission; multiple auxiliary rollers 925 are installed between nut packaging bag roller 92 and winding part 918.

[0053] The nut packaging bag strip 93 on the nut packaging bag roller 92 is tangentially connected to multiple auxiliary rollers 925 and extends to the winding component 918. The winding component 918 winds up the nut packaging bag strip 93 and wraps it in the guide cylinder 919, and then passes downward through the shaping component 924, the hot melt welding component 920, the traction roller group 921, and the heat sealing and cutting component 922.

[0054] It should be noted that the heat-sealing and cutting component 922 has both heat-sealing and cutting functions. After the nut packaging bag strip 93 is rolled by the shrinking component 918 and the shaping component 924, it forms a cylindrical structure. At this time, the sides of the cylindrical structure are sealed and the bottom is open. After the cylindrical structure is pulled to the heat-sealing and cutting component 922 by the pulling roller assembly 921, the heat-sealing and cutting component 922 heat-seals the opening of the cylindrical structure. Then, the nuts unloaded from the packaging tube 911 are loaded into the cylindrical structure. The pulling roller assembly 921 pulls the cylindrical structure down to the set position again, and the heat-sealing and cutting component 922 performs heat sealing and cutting to obtain the bagged nut product.

[0055] The positioning sensor 923 is used to position the downward movement of the cylindrical structure, and the heat-sealing cut-off part 922 performs heat sealing and cutting based on the positioning data information of the positioning sensor 923.

[0056] One end of the partition 910 is attached to the inner side of the packaging tube, while the other end is spaced apart from the inner side of the packaging tube, forming a gap. The partition divides the packaging tube into two parts. One part is close to the guide plate 97, receiving the macadamia nuts discharged from the guide plate 97, and the macadamia nuts are filled into the metering cylinder in this part. An overflow port is provided on the partition 910, and there is a certain gap between the overflow port and the packaging tube 911. A guide plate 912 is installed at the overflow port. When the packaging tube rotates, it moves the metering cylinder 913 and the macadamia nuts inside. The macadamia nuts that are stacked above the overflow port enter the packaging tube on the other side of the partition 910, and then fall into the metering cylinder through the falling hole due to the obstruction of the guide plate 912.

[0057] The traction roller assembly 921 includes two rollers and a roller motor. The two rollers are arranged in parallel and tangentially connected. One roller is mounted to the nut-making machine frame via a support shaft, and the roller motor is mounted to the nut-making machine frame and is driven by the other roller. The two rollers clamp the heat-sealed side of the cylinder structure, and the roller motor drives the rollers to rotate, with the two rollers working together to pull the cylinder structure to move.

[0058] To facilitate observation of the kernels on the side of the packaging cylinder 911 near the guide plate 97, a kernel camera 99 is installed on the partition 910. The kernel camera 99 monitors in real time the kernels falling into the metering cylinder from the packaging cylinder.

[0059] How a nut packaging machine works:

[0060] After being sterilized by an ultraviolet sterilization unit, the nuts are conveyed by a nut elevator to a nut discharge hopper 96. The nut discharge hopper 96 unloads the nuts onto a guide plate 97, which then conveys them to a packaging cylinder 911. Inside the packaging cylinder 911, under the action of a partition 910, the nuts fall through the discharge hole at the bottom of the packaging cylinder 911 into a metering cylinder 913. The nut packaging motor 94 drives a rotating shaft 916 to rotate, which in turn drives the packaging cylinder 911 to rotate. The packaging cylinder 911 then drives the metering cylinder 913 to rotate. When the metering cylinder 913 rotates to the discharge port on the blocking plate 914, the nuts inside the metering cylinder 913 fall through the discharge port into a guide funnel 917, and then into a guide cylinder 919. At this time, the nut packaging bag strip 93 forms a cylindrical structure after being rolled by the shrinking part 918 and the shaping part 924. At this time, the sides and bottom of the cylindrical structure are heat-sealed. After the nuts fall into the cylindrical structure, the pulling roller group 921 pulls the cylindrical structure down to the set position monitored by the positioning sensor 923. At this time, the heat-sealing and cutting part 922 squeezes the cylindrical structure to perform transverse heat sealing and cutting at the same time, thus obtaining the bagged nut product.

[0061] In some alternative embodiments, one structure of the nut shell packaging mechanism is provided. For example... Figure 3 As shown, the fruit shell packaging mechanism includes a receiving funnel 11, a combination weigher 12, a guiding funnel 13, a discharging funnel 14, a bagging lifting drive 19, a bagging funnel 16, a vibrator 18, a turntable mechanism 24, a bag opening mechanism 29, a bag feeding mechanism 27, a bag feeding mechanism 28, and a discharging conveyor 26.

[0062] The receiving funnel 11 is used to receive shelled nuts discharged from the shell elevator; the combined scale 12 is installed at the bottom of the receiving funnel 11 to weigh the weight of the shelled nuts falling into it; the guiding funnel 13 is installed at the bottom of the combined scale 12 to receive shelled nuts discharged from it; one end of the unloading funnel 14 is connected to the guiding funnel 13, and the other end is equipped with an unloading control valve 15; the bagging lifting drive 19 is connected to the bracket 17, driving the bracket 17 to rise and fall; the bagging funnel 16 is installed on the bracket and placed at the bottom of the unloading control valve 151; the vibrator 18 is installed on the bracket. 17; The turntable mechanism 24 has multiple sets of bag claws distributed around its circumference. The bag claws 25 are used to clamp the packaging bags. The turntable mechanism 24 drives the bag claws 25 to rotate to the bottom of the bagging funnel 16. The bag opening mechanism 29 is installed near the turntable mechanism 24 and is used to open the bag opening of the packaging bag clamped on the bag claws 25. The bag feeding mechanism 27 is installed near the turntable mechanism 24 and is used to store the packaging bags. The bag feeding mechanism 28 is installed between the turntable mechanism 24 and the bag feeding mechanism 27 and is used to grab the packaging bags on the bag feeding mechanism 27 and switch them to the bag claws 25. The unloading conveyor 26 is used to receive the packaging bags unloaded from the turntable mechanism 24.

[0063] Understandably, the bottom of the metering cylinder is open, and a discharge port is provided on the blocking plate 914. When the metering cylinder rotates with the packaging cylinder to the discharge port, the macadamia nuts inside the metering cylinder fall into the guide funnel through the discharge port.

[0064] The unloading control valve 15 includes an unloading drive 151 and an unloading swing plate 152. The unloading swing plate 152 is hinged to the unloading funnel 14. One end of the unloading drive 151 is movably mounted on the unloading funnel 14, and the other end is drivenly connected to the unloading swing plate 152. The unloading drive 151 drives the unloading swing plate 152 to open and close relative to the unloading funnel 14. When the unloading drive 151 drives the unloading swing plate 152 to open, the unloading funnel 14 unloads material. When the unloading drive 151 drives the unloading swing plate 152 to close at the bottom of the unloading funnel 14, the unloading funnel 14 stops unloading material. The unloading control valve 15 prevents the shelled nuts discharged from the guide funnel 13 from falling directly into the bagging funnel 16.

[0065] Understandably, the combination scale 12 is used to weigh the shelled nuts that need to be packaged.

[0066] One structure of the bag opening mechanism 29 includes a bag opening support frame 291, a base plate 292, a bag opening guide plate 293, a bag opening drive component 294, a movable negative pressure manifold 295, a negative pressure suction plate 296, a fixed negative pressure manifold 297, and a fixed negative pressure suction cup 298. The base plate 292 is mounted on the bag opening support frame 291. The bag opening guide plate 293 is fitted onto the base plate 292. The bag opening drive component 294 is mounted on the base plate 292 and is connected to the guide plate 293 in a transmission manner. The bag opening drive component 294 drives the guide plate 293 to slide along the base plate. The movable negative pressure manifold 295 is mounted on the guide plate 293. At least two negative pressure suction plates 296 are mounted on the movable negative pressure manifold 295. The fixed negative pressure suction cup 298 is mounted on the fixed negative pressure manifold 297 corresponding to the negative pressure suction plates 296. The fixed negative pressure manifold 297 is mounted on the turntable mechanism 24.

[0067] Working principle of bag opening mechanism 29: When the turntable mechanism 24 rotates the packaging bag between the negative pressure adsorption plate 296 and the fixed negative pressure suction cup 295 through the bag claw 25, the negative pressure adsorption plate 296 and the fixed negative pressure suction cup 295 adsorb one side of the packaging bag respectively. The bag opening drive component 294 drives the bag opening guide plate 293 to move away from the fixed negative pressure suction cup 295. The bag opening guide plate 293 drives the movement of the movable negative pressure main pipe 295 and the movement of the pipe installed on it. The negative pressure adsorption plate 296 and the fixed negative pressure suction cup 298 interact to open the bag opening.

[0068] How a fruit shell packaging facility works:

[0069] The bag feeding mechanism 28 picks up a packaging bag from the bag feeding mechanism 27 and sends it to a set of bag claws 25 on the turntable mechanism. The turntable mechanism 24 drives the bag claws 25 and the packaging bag to rotate to the bag opening mechanism 29. The bag opening mechanism 29 opens the bag opening, and the turntable mechanism 24 then rotates the opened packaging bag to the bottom of the bag filling funnel 16.

[0070] The shell elevator 10 conveys the shelled nuts to the receiving funnel 11. The receiving funnel 11 then slowly rolls the shelled nuts onto the combined scale 12. The combined scale 12 weighs the rolling shelled nuts and accumulates the weight. When the set weight is reached, the unloading control valve 15 opens, and the shelled nuts in the unloading funnel 14 fall into the bagging funnel 16. The bagging lifting drive 19 drives the support 17 and the bagging funnel 16 to move down. The bagging funnel 16 inserts into the packaging bag held on the bag claw 25 below. The vibrator 18 is started, which drives the bagging funnel 16 to vibrate, so that the shelled nuts unloaded from the bagging funnel 16 fill the packaging bag.

[0071] The bagging lifting drive 19 drives the bracket 17 and the bagging funnel 16 to rise and reset. The turntable mechanism 24 drives the packaging bag containing shelled nuts to rotate to the heat sealing mechanism (not shown in the figure) for sealing. After sealing, the bag claws can release the grip, and the packaging bag falls into the unloading conveyor 26. The unloading conveyor 26 carries the packaging bag away from the turntable mechanism.

[0072] In some optional embodiments, in order to facilitate the insertion of the bagging funnel 16 into the open packaging bag, a fixed frame 21, a swing rod 22, a first support plate 20, and a second support plate 23 are added; the first support plate 20 and the second support plate 23 are installed in an inverted V-shape; the fixed frame 21 is installed on the turntable mechanism 24, one end of the swing rod 22 is movably connected to the fixed frame 21, and the other end is connected to the first support plate 20, and the swing rod 22 has a bent structure and is hinged to the unloading funnel 16 at the bend; the second support plate 20 is installed on the fixed frame.

[0073] The first expansion plate 20 moves along with the bagging funnel 16 and cooperates with the second expansion plate 20 to help open the bag opening, making it easier for the bagging funnel to be inserted into the packaging bag.

[0074] In some alternative embodiments, one structure of the bag-feeding mechanism is provided. For example... Figure 5As shown, the bag feeding mechanism 28 includes a support column 281, a drive plate 288, a clamping support body 2813, a fixed leg 284, a movable leg 285, a guide plate 2810, a sliding rod 2812, and a limiting rod 289. A swing drive component 2811 is mounted on the support column 281; the drive plate 288 is pulsatorically connected to the swing drive component 2811; the clamping support body 2813 is pulsatorically connected to the drive plate 288; the fixed leg 284 is mounted on the clamping support body 2813, and a fixed clamp 283 is mounted on it; the movable leg 285 is hinged to the clamping support body 2813, one end of which is mounted with a movable clamp 282, and the other end is pulsatorically connected to the clamping drive component 286 mounted on the clamping support body 2813; the guide plate 2810 is mounted on the support column 281 and has a guide groove; one end of the sliding rod 2812 is movably mounted in the guide groove; one end of the limiting rod 289 is rotatably connected to the clamping support body 2813, and the other end is hinged to the sliding rod 2812.

[0075] Both the swing drive component 2811 and the clamping drive component 286 can adopt a pneumatic cylinder structure. The pneumatic cylinder structure operates quickly and smoothly.

[0076] How the bag feeding mechanism works:

[0077] The clamping drive 286 pushes one end of the movable leg 285, which is hinged to the clamping support 2813. Therefore, the other end of the movable leg 285 drives the movable clamp 282 to move toward the fixed clamp 283. The movable clamp 282 and the fixed clamp 283 clamp each other to hold the packaging bag given by the bag feeding mechanism 27. The swing drive 2811 drives the drive plate 288 to swing. The drive plate 288 drives the clamping support 2813 to swing through the connecting shaft 287. The clamping support 2813 drives the movable clamp 282, the fixed clamp 283, and the packaging bag held by the movable clamp 282 and the fixed clamp 283 to swing towards the bag claw 25 on the turntable mechanism 24. When the swing reaches the set swing stroke of the swing drive 2811, the bag claw 25 clamps the movable clamp 282 and the fixed clamp 283 to clamp the delivered packaging bag, realizing the switching of the packaging bag on the bag mechanism to the bag claw. The swing drive 2811 drives the clamping support 2813 to swing back to its original position, and the movable clamp 282 and the fixed clamp 283 clamp the next packaging bag.

[0078] In some alternative embodiments, one structure of the bag-feeding mechanism is provided. For example... Figure 6As shown, the bag feeding mechanism includes a support plate 276, a spacing adjustment component, a guide slide component, an adjustable slide rod 274, a bag suction bracket 2712, a suction cup bracket 2714, a bag suction lifting drive component 2713, an air nozzle 2720, and an air jet component 2718. The support plate 276 has a through groove 2761 and a support leg 279 installed at its bottom. Two parallel and spaced packaging bag limiting plates 271 are installed in the through groove 2761. The spacing adjustment component is installed at the bottom of the support plate 276 and connected to the packaging bag limiting plates 271, used to adjust the spacing between the two packaging bag limiting plates 271 so that the spacing between the two packaging bag limiting plates is suitable for different packaging bag sizes. The guide slide component is installed at the bottom of the support plate and connected to the packaging bag limiting plates 271, used to assist in guiding the sliding of the packaging bag limiting plates 271. One end of the adjustable slide rod 274 is inserted between the two packaging bag limiting plates 271 and a limiting stop. The connection 273 is connected to the support plate 276 via a tension adjustment component 275; the suction bag lifting drive component 2713 is installed at the bottom of the through groove 2761; the suction bag bracket 2712 is installed on the suction bag lifting drive component 2713, and the suction bag lifting drive component 2713 can drive the suction bag bracket 2712 to rise and fall; the suction bag bracket 2712 is equipped with at least one suction cup bracket 2714, and at least two suction cups 2715 are installed on the suction cup bracket 2714; at least two air nozzles 2720 are installed at the bottom of the packaging bag limiting plate 271; the air jet component 2718 is installed on the support plate 276 and is used to spray gas between the two packaging bag limiting plates 271.

[0079] The adjustable slide rod 274 has a groove 2741, and one end of the tension adjusting member 275 passes through the groove 2741 and is threadedly connected to the support plate 276. When the tension adjusting member 275 is tightened, it presses the adjustable slide rod 274 to fix it to the support plate 276. When the tension adjusting member 275 is loosened, the adjustable slide rod 274 can move relative to the support plate 276.

[0080] The spacing adjustment component and the guide slide component work together to allow the two packaging bag limiting blocks 271 to move within the through groove 2761. The two packaging bag limiting blocks 271 form an accommodating space 272, within which multiple packaging bags are stacked.

[0081] Furthermore, in this embodiment, a structure for the spacing adjustment member is provided. For example... Figure 6As shown, the spacing adjustment component includes a fixed support 2710, a screw 278, threaded sliders 277, and an adjusting wheel 2711. Two fixed supports 2710 are spaced apart and installed on the bottom surface of the support plate 276. The screw 278 passes through the two fixed supports 2710, with one of the fixed supports connecting to the adjusting wheel 2711. Two threaded sliders 277 are spaced apart and installed parallel to each other on the screw 278. The threaded sliders 277 are threadedly connected to the screw 278 and are connected to the packaging bag limiting plate 271. It is understood that in order to achieve the two threaded sliders 277 moving in different directions when the screw 278 rotates, the thread directions on the two threaded sliders are opposite.

[0082] Furthermore, in this embodiment, one structure of the guide slide is provided. For example... Figure 6 As shown, the guide slide includes a bearing seat 2717, a guide rod 2716 and a slider (not shown in the figure). Two bearing seats 2717 are installed in parallel at intervals on the bottom surface of the support plate 276. The guide rod 2716 passes through the two bearing seats 2717. Two sliders are installed on the guide rod 2716. The sliders can slide along the length of the guide rod.

[0083] The number of suction cup brackets 2714 installed on the suction bag bracket 2712 can be 1, 2, 3, 4, 5 or 6, etc.

[0084] The number of suction cups 2715 installed on the suction cup bracket 2714 can be 2, 3, 4, 5, 6, 7, 8, 9 or 10, etc.

[0085] The number of air nozzles 2720 installed at the bottom of the packaging bag limiting plate 271 can be 2, 3, 4, 5 or 6, etc.

[0086] How the bag feeding mechanism works:

[0087] The spacing adjustment component and the guide slide component work together to adjust the spacing between the two packaging bag limiting plates 271.

[0088] The packaging bag is placed into the accommodating space 272 formed by the two packaging bag limiting plates 271. The suction bag lifting drive 2713 lifts the suction bag bracket 2712 upward. The suction bag bracket 2712 drives the suction cup bracket 2714 and the suction cup 2715 mounted on the suction cup bracket 2714 to move upward. While the suction cup 2715 passes through the through groove 2761 to suck up the packaging bag in the accommodating space 272, the air nozzle 2720 and the air jet component 2718 simultaneously spray compressed air into the accommodating space 272, so that the packaging bag not sucked up by the suction cup can be sucked up. The bag floats upward, and the suction cup 2715 moves downward and separates from the support plate 276, driven by the suction cup lifting drive 2713. The suction bag and the other bags are then separated into layers, allowing the bag sucked by the suction cup 2715 to quickly leave the holding space while avoiding pulling another bag out of the holding space. The suction cup lifting drive 2713 moves the suction cup 2715 downward to the set stroke, and the bag feeding mechanism grabs the bag on the suction cup. The suction cup loses its negative pressure effect, and there is no suction between the suction cup and the bag. The bag feeding mechanism then grabs the bag and separates it from the bag feeding mechanism.

[0089] like Figure 1 As shown, a discharge hopper is added to facilitate the collection of macadamia nuts unloaded from the conveyor belt; a discharge hopper is installed on the ultraviolet sterilizer 2 near the tunnel outlet.

[0090] The sides and top of the sterilization tunnel are made of mirror-finish stainless steel. Mirror-finish stainless steel is characterized by its corrosion resistance, high temperature resistance, rust resistance, and ease of manufacturing.

[0091] like Figure 8-10 As shown, one structure of a feeding conveyor is given. The feeding conveyor includes a frame 81, a feeding conveyor belt 810, a pressure roller 88, a baffle 83, a pusher plate 89, a motor frame 815, and a drive motor 815. The frame 81 has an upwardly bent structure. A driven roller 82 is rotatably mounted on one end, and a driving roller 816 is rotatably mounted on the other end. Multiple auxiliary rollers 85 are installed at intervals along the length of the frame 81. One end of the feed conveyor belt 810 is drivenly connected to the driven roller 82, and the other end is drivenly connected to the driving roller 816. Pressure rollers 88 are installed on both sides of the bend of the frame. The pressure rollers 88 squeeze the feed conveyor belt 810 located on the top surface of the frame 81 against the multiple auxiliary rollers 85. Baffles 83 are installed on both sides of the top surface of the frame 81. The baffles 83 and the pressure rollers 88 are arranged side by side. Multiple push plates 89 are installed at intervals on the feed conveyor belt 810. The motor frame 815 is mounted on the frame 81. The drive motor 814 is mounted on the motor frame 815 and is drivenly connected to the driving roller 816.

[0092] Both the driving roller 816 and the driven roller 82 are rotatably mounted on the frame 81.

[0093] A transmission connection structure between the drive motor 814 and the drive roller 816 includes a driven wheel 811, a transmission component 812, and a drive wheel 813. The drive wheel 813 is mounted on the output shaft of the drive motor 814. A rotating shaft is provided at one end of the drive roller 816, and the driven wheel 811 is mounted on the rotating shaft. The driven wheel 811 and the drive wheel 813 are connected by the transmission component 812. Working principle: The drive motor 814 drives the drive wheel 813 to rotate. The drive wheel 813 drives the driven wheel 811 to rotate through the transmission component 812. The driven wheel 811 drives the rotating shaft to rotate. The rotating shaft drives the drive roller 816 to rotate. The drive roller 816 drives the feeding conveyor belt 810 to rotate. The feeding conveyor belt 810 drives the auxiliary roller 85 and the driven roller 82 to rotate.

[0094] like Figure 1-3 As shown, the motor frame 815 is mounted on top of the frame 81 and the baffle 83.

[0095] like Figure 1-3 As shown, baffles 83 are installed on both sides of the feeding conveyor belt 810 in the direction of rotation. The baffles on both sides can prevent macadamia nuts from running off the feeding conveyor belt. Multiple push plates are installed at intervals on the feeding conveyor belt. The push plates and the baffles on both sides form multiple cells. The feeding conveyor belt transports macadamia nuts unloaded from the storage bin to the waiting bin through multiple cells.

[0096] like Figure 1-3 As shown, there is a gap between the baffle and the edge of the feed conveyor belt 810, so the baffle does not affect the pressure roller's squeezing of the feed conveyor belt.

[0097] like Figure 8-10 As shown, a structure for mounting a baffle on a frame is provided, with the addition of a baffle bracket 84. The baffle 83 is mounted on the frame 81 via multiple baffle brackets 84; each baffle bracket 84 includes a support 841, an adjusting screw 842, a baffle adjusting nut 843, and a baffle positioning nut 844. The adjusting screw 842 passes through the support 841 and connects to the baffle 83, with the baffle adjusting nut 843 mounted on one side of the adjusting screw located on the support 841 and the baffle positioning nut 844 mounted on the other side.

[0098] The adjusting screw 842 is threadedly connected to the baffle adjusting nut 843 and the baffle positioning nut 844. By adjusting the position of the baffle positioning nut 844 on the adjusting screw 842, the distance between the baffle and the edge of the feed conveyor belt 810 can be adjusted. Tightening the baffle adjusting nut clamps the support 841 with the baffle positioning nut, thus fixing the adjusting screw 842, baffle adjusting nut 843, and baffle positioning nut 844 to the support. Loosening the baffle adjusting nut allows the baffle adjusting screw to move.

[0099] like Figure 9As shown, the baffle bracket 84 also includes a nut support 845. The nut support 845 is fixedly installed on the baffle 83. The adjusting screw 842 is threadedly connected to the nut support 845, realizing a detachable connection between the adjusting screw and the nut support. Alternatively, the adjusting screw 842 and the nut support 845 are welded and fixedly connected.

[0100] like Figure 8 , 10 As shown, a structure for mounting the pressure roller on the frame is provided, which includes an additional support shaft 87, a support plate 86, a pressure roller adjusting nut 817, and a pressure roller positioning nut 818. One end of the support shaft 87 is rotatably connected to the pressure roller 88, and the other end passes through the support plate 86; the pressure roller adjusting nut 817 is mounted on the support shaft 87 on one side of the support plate 86 and is threadedly connected to the support shaft 87; the pressure roller positioning nut 818 is mounted on the support shaft 87 on the other side of the support plate 86 and is threadedly connected to the support shaft 87.

[0101] The support shaft is mounted on the support plate 86 via the pressure roller adjusting nut 817 and the pressure roller positioning nut 818, so that the support shaft and the support plate can be detachably installed.

[0102] Both the pressure roller adjusting nut 817 and the pressure roller positioning nut 818 are threadedly connected to the support shaft. Tightening the pressure roller positioning nut 818 adjusts its position on the support shaft. In use, tightening the pressure roller adjusting nut 817 clamps and fixes it to the support plate 86 with the pressure roller positioning nut 818. The support shaft is then fixedly installed on the support plate 86, allowing the pressure roller 88 to be detachably mounted on the support plate 86 via the support shaft. Loosening the pressure roller adjusting nut 817 allows the support shaft to move relative to the support plate. It is understood that the position of the pressure roller positioning nut 818 on the support shaft can be adjusted as needed, thereby adjusting the distance between the pressure roller and the support plate, and also adjusting the length of the pressure roller pressing against the feed conveyor belt 810.

[0103] like Figure 8 As shown, to prevent the multiple push plates on the feed conveyor belt from rubbing against the baffles during movement, there is a gap between the two ends of the push plate 89 and the corresponding baffle 83, the gap being smaller than the diameter of the macadamia nut. This prevents the push plate from rubbing against the baffles during movement and also prevents the macadamia nut from rolling out through the gap.

[0104] A method of using a macadamia nut packaging machine according to any one of the above embodiments, the method comprising:

[0105] Macadamia nuts are conveyed to the ultraviolet sterilization unit via a feeding conveyor. The ultraviolet sterilization unit sterilizes the macadamia nuts with ultraviolet light, and they are unloaded after passing the sterilization.

[0106] When macadamia nuts are unloaded, the diverter connects to the nut elevator, which then transports the macadamia nuts to the nut packaging mechanism, which packages the delivered macadamia nuts according to the specified quantity.

[0107] When the unloaded nuts are macadamia nuts in their shells, the diverter connects to the shell elevator, which then transports the nuts to the shell packaging mechanism. The shell packaging mechanism then packages the nuts by weight.

[0108] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
