Description

Technical Field

[0001] This invention relates to the field of hardware packaging technology, specifically a dual-station automatic weighing and electromagnetic sorting cartoning machine. Background Technology

[0002] Hardware refers to the five metals: gold, silver, copper, iron, and tin, which, through artificial processing, can be made into works of art such as knives and swords, or metal components. In modern society, hardware is much broader, including hardware tools, hardware parts, daily-use hardware, building hardware, and security products. In the mass production of hardware fasteners and small metal parts, dual-station automatic weighing electromagnetic sorting and boxing equipment relies on a weighing box to quantitatively measure the material. Then, the metal workpiece is guided through a hopper to a lower funnel and fall into a cardboard box to complete the filling process.

[0003] Existing equipment typically stores the material temporarily in a hopper or feeding box after weighing, and then the material is fed into a funnel by the hopper, and after being electromagnetically sorted, it falls into the packaging box to complete the boxing process.

[0004] The inventors of this application discovered in their research that the core defect of the above-mentioned prior art is that: the discharge end of the hopper mostly adopts a fixed opening structure, or uses an independent drive mechanism such as a cylinder or motor to control the opening and closing of the baffle. Its opening and closing action mainly relies on the electronic control program or pneumatic actuator. After one feeding is completed, the discharge end cannot be closed immediately. The residual material is prone to continuous leakage during equipment vibration, inertia or subsequent operation, which can easily lead to material leakage or premature spillage during the waiting period. Summary of the Invention

[0005] This invention provides a dual-station automatic weighing and metering, electromagnetic sorting and cartoning machine, which solves the problem of material leakage or premature spillage during the waiting period, and achieves the effect of quantitative feeding without leakage or premature spillage.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a dual-station automatic weighing and electromagnetic sorting cartoning machine, comprising a base, an elevator and a conveyor respectively arranged on the outer side of the base, a vibrating hopper at the feed end of the elevator, a distributing hopper at the discharge end of the elevator, a vibrating plate on the outer side of the distributing hopper, a conveying hopper installed on the outer wall of the distributing hopper, a weighing box on the lower side of the conveying hopper, a feeding hopper on the lower side of the weighing box, a hollow frame installed on the lower surface of the conveyor, an electromagnetic sorting machine installed on the inner wall of the hollow frame, a limiting component installed on the outer wall of the rotating shaft of the feeding hopper, and an opening and closing mechanism provided on the outer wall of the limiting component; The opening and closing mechanism includes a gear, the inside of which is disposed on the outer wall of the limiting member. The tooth end of the gear is meshed with a toothed plate, and a magnetic block is installed on the outer wall of the toothed plate. A magnetic block is magnetically repelled on the outer side of the magnetic block.

[0007] By adopting the above technical solution, the weighing box receives the metal material conveyed by the conveyor hopper. At the same time, when the weight is insufficient, it can also receive part of the metal material conveyed by the vibratory feeder. After reaching the set weight, the discharge hopper receives the quantitative material discharged from the weighing box. As a transfer and guiding component, it guides the material to flow downward to the subsequent process. The power of the rotating shaft of the conveyor belt inside the discharge hopper is transmitted through the limiting component to drive the opening and closing mechanism. The opening and closing of the discharge hopper outlet can be automatically controlled without additional electric control drive, accurately controlling the timing of material release and avoiding irregular and continuous spillage of material.

[0008] Preferably, an L-shaped frame is installed on the outer wall of the second magnetic block, a baffle is installed on the outer wall of the L-shaped frame, a slide rail is slidably connected inside the first toothed plate, the outer wall of the slide rail is installed on the outer wall of the hopper, both ends of the L-shaped frame are rotatably connected to the inside of the hopper, one end of a torsion spring is installed on the outer wall of the L-shaped frame, and the other end of the torsion spring is installed inside the hopper.

[0009] Preferably, the tooth ends of the first gear are meshed with a second toothed plate, a slide plate is slidably connected inside the second toothed plate and installed on the outer wall of the hopper, a vibrating frame is installed on the lower surface of the second toothed plate, a fixing rod is installed on the upper surface of the second toothed plate, and a tooth block is slidably connected to the outer wall of the fixing rod.

[0010] Preferably, one end of a spring is mounted on the lower surface of the toothed block, the other end of the spring is mounted on the upper surface of the toothed plate, and a ball is mounted inside the toothed block.

[0011] Preferably, the lower surfaces of the conveying hopper, weighing box, and vibratory plate are all mounted on the upper surface of the base, and the outer wall of the feeding hopper is mounted inside the base.

[0012] Preferably, a movable frame is slidably connected inside the hollow frame, and a funnel is installed on the inner wall of the movable frame, with the funnel located on the lower side of the vibration frame.

[0013] Preferably, a rack is mounted on the lower surface of the funnel, and a gear is meshed with the tooth end of the rack. The gear is internally rotatably connected to the outer wall of the hollow frame, and the tooth end of the gear is meshed with the rack.

[0014] Preferably, a transmission plate is installed on the outer wall of the rack 2, the outer wall of the transmission plate is slidably connected to the inside of the hollow frame, and a moving rod is slidably connected to the inside of the transmission plate.

[0015] Preferably, the movable rod is internally slidably connected to a slide rod, the bottom end of which is mounted on the upper surface of the hollow frame, and a spring is installed between the movable rod and the hollow frame.

[0016] Preferably, a U-shaped block is installed on the outer wall of the moving rod, a paper box is provided on the inner side of the U-shaped block, the inner side of the paper box is located on the outer side of the funnel, and the lower surface of the paper box is located on the upper surface of the conveyor.

[0017] By adopting the above technical solution, when the funnel moves up and down with the moving frame, the transmission plate is driven to move left and right through gear two, rack one and rack two. As the transmission plate moves, the U-shaped block moves up and down. The inner side of the U-shaped block matches the outer side of the paper box. Thus, when the paper box moves to the lower side of the funnel, the U-shaped block guides and limits the paper box simultaneously as the funnel moves down, preventing the paper box from shifting due to material impact.

[0018] This invention provides a dual-station automatic weighing and electromagnetic sorting cartoning machine. It has the following advantages: 1. This invention utilizes an opening and closing mechanism. During the operation of the hopper, the toothed plate and magnetic block 1 move upward, applying a repulsive force to the magnetic block 2, causing the baffle to rotate with the L-shaped frame, opening the discharge end of the hopper, and conveying the material to the funnel. When the hopper stops, the funnel moves upward, pushing the toothed plate 2, which in turn resets its connecting structure via gear 1, closing the discharge end of the hopper again. No electrical or pneumatic control is required. The feeding action is synchronized with the opening sequence of the hopper outlet, achieving quantitative feeding without leakage or premature spillage, while preventing continuous leakage or premature falling into the funnel during the waiting period. By setting a dual-station structure and a dual-weighing structure, the overall boxing speed can be improved.

[0019] 2. In this invention, when the funnel moves downward and is inserted into the inside of the cardboard box, the hopper operates to transport materials. Through the rotation of the shaft and a pair of gears, the gears and the vibrating frame move downward. The fixed rod, spring, and toothed blocks adapt to the rotation of the gears. The movement of the toothed blocks applies downward pressure to the gears and the vibrating frame through the ball bearings. At this time, the vibrating frame contacts the funnel and applies vibration to the funnel. This prevents the material from the previous batch from being mixed into the material of the next box when the funnel receives the material, and prevents the mixing of hardware of different specifications.

[0020] 3. This invention, by setting up gear two, rack one, rack two, transmission plate and moving rod, drives the transmission plate to move when the funnel moves down. The inclined groove inside the transmission plate causes the U-shaped block to move down. The inclined inner side of the U-shaped block facilitates the guidance of the paper box and pushes the paper box to move slightly, so that its center is aligned with the center of the lower opening of the funnel. This allows the material to fall stably into the paper box and prevents the material from spilling. At the same time, the U-shaped blocks on both sides limit the paper box and prevent it from sliding left and right, warping, or tipping when the paper box is impacted by the falling metal workpiece.

[0023] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. 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.

[0024] Please see the appendix Figure 1 - Appendix Figure 9This invention provides a dual-station automatic weighing and electromagnetic sorting cartoning machine, including a base 1. An elevator 2 and a conveyor 9 are respectively arranged on the outer side of the base 1. A vibrating bucket 3 is arranged at the feeding end of the elevator 2, and a distributing bucket 4 is arranged at the discharging end of the elevator 2. A vibrating plate 7 is arranged on the outer side of the distributing bucket 4. A conveying bucket 5 is installed on the outer wall of the distributing bucket 4. A weighing box 6 is arranged on the lower side of the conveying bucket 5. A feeding hopper 8 is arranged on the lower side of the weighing box 6. A hollow frame 10 is installed on the lower surface of the conveyor 9. An electromagnetic sorting machine 11 is installed on the inner wall of the hollow frame 10. A limiting component 12 is installed on the outer wall of the rotating shaft of the feeding hopper 8. An opening and closing mechanism 13 is arranged on the outer wall of the limiting component 12. The opening and closing mechanism 13 includes a gear 131, the inside of which is disposed on the outer wall of the limiting member 12. The tooth end of the gear 131 is meshed with a toothed plate 132. A magnetic block 134 is installed on the outer wall of the toothed plate 132. A magnetic block 135 is magnetically repelled on the outside of the magnetic block 134.

[0025] Specifically, the vibrating bucket 3 uses vibration to break up the piled-up workpieces, continuously feeding small metal parts to be weighed to the feed end of the elevator 2. The elevator 2 lifts the metal hardware workpieces in the vibrating bucket 3 upwards and conveys them to the distribution bucket 4. The distribution bucket 4 receives the material output from the elevator 2 and distributes the material to the conveyor bucket 5 and the vibrating plate 7. The conveyor bucket 5 has a conveying component on its inner side to receive the material from the distribution bucket 4 and convey it at a uniform speed to the weighing box 6 below. The weighing box 6 has a built-in weighing sensor unit to accurately measure the weight of the metal material in the box. When the set weight is reached, the unloading action is triggered. When the material inside the weighing box 6 is insufficient, the vibrating plate 7 vibrates and conveys the material inside the vibrating plate 7 into the weighing box 6. The unloading bucket 8 receives the material after the weighing box 6 has been weighed. The external opening and closing mechanism 13 controls the material flow and guides the weighed metal workpieces downwards to the next process. The conveyor 9 serves as a packaging conveyor line, continuously conveying empty packaging boxes to the boxing station below the magnetic component of the electromagnetic sorting machine 11. After boxing, the finished packaging boxes are output. The packaging box is continuously circulated and transferred. The limiting component 12 consists of a ratchet, a limiting block, a short rod, and an elastic element. When the ratchet rotates outward following the direction of the shaft, it abuts against the limiting block, which is inside gear 131, thus driving gear 131. When the ratchet and shaft stop rotating, gear 131 can be subjected to external force, causing the ratchet and gear 131 to rotate in opposite directions. At this time, there is no metal material inside the hopper 8, and the rear side of the hopper 8 is closed, containing only the contents of the hopper 8. The front is open, and the opening and closing mechanism 13 allows the discharge end of the hopper 8 to be automatically released during operation and to be automatically reset to close the discharge end of the hopper 8 when stopped, thus achieving quantitative feeding without leakage or premature spillage. The above equipment is arranged in a stacked configuration to facilitate dual-station processing. The above equipment is controlled by a main control button. Since the equipment matched with the control button is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0026] Please see the appendix Figure 3 - Appendix Figure 5 An L-shaped frame 136 is installed on the outer wall of the magnetic block 135. A baffle 137 is installed on the outer wall of the L-shaped frame 136. A slide rail 133 is slidably connected inside the toothed plate 132. The outer wall of the slide rail 133 is installed on the outer wall of the hopper 8. Both ends of the L-shaped frame 136 are rotatably connected to the inside of the hopper 8. One end of a torsion spring 138 is installed on the outer wall of the L-shaped frame 136. The other end of the torsion spring 138 is installed inside the hopper 8.

[0027] Specifically, the toothed plate 132 moves upward, driving the magnetic block 134 to approach and repel the magnetic block 135, thereby pushing the L-shaped frame 136 to rotate inside the hopper 8. The L-shaped frame 136 drives the baffle 137 to rotate, thereby opening the discharge end of the hopper 8 to convey materials. The torsion spring 138 absorbs the force of the L-shaped frame 136's rotation and provides a restoring force to the baffle 137 when the magnetic block 134 moves away from the magnetic block 135.

[0028] Please see the appendix Figure 5 The tooth ends of gear 131 are meshed with a toothed plate 14. A sliding plate is slidably connected inside the toothed plate 14 and installed on the outer wall of the hopper 8. A vibrating frame 15 is installed on the lower surface of the toothed plate 14, and a fixing rod 16 is installed on the upper surface of the toothed plate 14. A toothed block 30 is slidably connected to the outer wall of the fixing rod 16. One end of a spring 17 is installed on the lower surface of the toothed block 30, and the other end of the spring 17 is installed on the upper surface of the toothed plate 14. A ball 18 is installed inside the toothed block 30.

[0029] Specifically, gear 131 meshes with gear plate 132 and gear plate 14 on its front and rear sides respectively. When gear 131 rotates in the conveying direction, it drives gear plate 14 to move downward. Utilizing the fixed rod 16, spring 17, and gear block 30, when gear plate 14 moves to its lower limit, the downward movement and reset of gear block 30 adapt to the rotation of gear 131. Meanwhile, the ball 18 applies an intermittent downward force to gear plate 14 through the downward movement of gear block 30. This force is transmitted through the vibration frame 15 and its... The lower ball bearings apply vibration to the lower material receiving component, thus preventing material residue from remaining on the inclined surface of the material receiving component. As the material receiving component moves upward, it presses against the vibrating frame 15, causing the second toothed plate 14 to move upward, driving the first gear 131 to rotate in the opposite direction. This resets the first toothed plate 132 and its connecting components. By utilizing the upward movement distance of the material receiving component and the matching number of teeth on the second toothed plate 14 and the first gear 131, the normal operation of the first gear 131 and its connecting components is ensured. Figure 5 It can be seen that a fixing rod 16, a spring 17 and a tooth block 30 can also be provided on the lower side of the tooth plate 132 to accommodate the rotation of the gear 131.

[0030] Please see the appendix Figure 2 The lower surfaces of the conveyor hopper 5, weighing box 6, and vibratory plate 7 are all mounted on the upper surface of the base 1, and the outer wall of the discharge hopper 8 is mounted inside the base 1.

[0031] Specifically, the base 1 is used to install and fix the conveyor hopper 5, weighing box 6 and vibratory plate 7, and also provides installation space for the discharge hopper 8.

[0032] Please see the appendix Figure 2 - Appendix Figure 7A movable frame 19 is slidably connected inside the hollow frame 10. A funnel 20 is installed on the inner wall of the movable frame 19, and the funnel 20 is located on the lower side of the vibration frame 15.

[0033] Specifically, a lifting component is provided on the lower side of the hollow frame 10 to drive the moving frame 19 to move up and down under the limit of the hollow frame 10. The funnel 20 is installed on the inner wall of the moving frame 19, thereby driving the funnel 20 to move up and down. The lifting component is a conventional hydraulic drive component, which will not be described in detail. The vibrating frame 15 is transmitted by its connecting structure to apply a vibration force to the funnel 20 so that the funnel 20 generates micro-vibration, which helps the material on its inner wall to be discharged.

[0034] Please see the appendix Figure 7 - Appendix Figure 9 A rack 22 is mounted on the lower surface of the funnel 20. The tooth ends of the rack 22 are meshed with a gear 21. The inside of the gear 21 is rotatably connected to the outer wall of the hollow frame 10. The tooth ends of the gear 21 are meshed with a rack 23. A transmission plate 24 is mounted on the outer wall of the rack 23. The outer wall of the transmission plate 24 is slidably connected to the inside of the hollow frame 10. A moving rod 25 is slidably connected inside the transmission plate 24. A sliding rod 27 is slidably connected inside the moving rod 25. The bottom end of the sliding rod 27 is mounted on the upper surface of the hollow frame 10. A spring 28 is installed between the moving rod 25 and the hollow frame 10. A U-shaped block 26 is mounted on the outer wall of the moving rod 25. A paper box 29 is provided on the inner side of the U-shaped block 26. The inner side of the paper box 29 is located on the outer side of the funnel 20. The lower surface of the paper box 29 is located on the upper surface of the conveyor 9.

[0035] Specifically, the funnel 20 can move up and down under the drive of the moving frame 19. When the conveyor 9 transports the paper box 29 to the lower side of the funnel 20, the funnel 20 moves down, driving the rack 22. The rack 22, through the gears 21 and 23, drives the transmission plate 24 to move left and right. Because the racks 23 and 22 are staggered, there is no motion interference. A short plate is provided on the outer wall of the transmission plate 24 and slides inside the hollow frame 10, thereby limiting the movement of the rack 23. An inclined groove is opened inside the transmission plate 24, and the moving rod 25 is located on the inner wall of the groove. As the transmission plate 24 moves, it drives the moving rod 25 and the U-shaped block 26 to move up and down. The U-shaped block 26 is located on the outside of the paper box 29. Utilizing the inclination of the inner side of the U-shaped block 26, as the U-shaped block 26 moves downward, it assists the paper box 29 in moving towards the center of the two U-shaped blocks 26, that is, towards the center of the discharge port on the lower side of the funnel 20. This prevents the paper box 29 from accidentally moving or shaking when receiving materials. The electromagnetic sorting machine 11, located below the funnel 20 and above the paper box 29, magnetically sorts the materials discharged from the funnel 20, allowing the materials to fall orderly into the interior of the paper box 29. After the material discharge is completed, the funnel 20, the transmission plate 24, and their connecting parts are reset to their original centers. Through the above structure, the U-shaped block 26 is prevented from being rigidly fixed in the funnel 20, which would require adjusting the clamping force and would necessitate modifying the overall structure of the funnel 20, making adjustment difficult.

[0036] Workflow: Metal hardware workpieces are poured into vibrating bucket 3. Vibrating bucket 3 vibrates and breaks up the accumulated material and sends it to the feed end of elevator 2. Elevator 2 lifts the workpiece vertically upward to the top distribution bucket 4. Distribution bucket 4 completes the material diversion. The outer vibrating plate 7 vibrates continuously to prevent workpieces from bridging and getting stuck. Conveyor bucket 5 receives the diverted workpieces and conveys them downward to the weighing box 6. When the workpieces in the box reach the preset boxing weight, the upstream conveying stops, completing the single-quantity material storage.

[0037] After weighing, the material is fed into the lower hopper 8. At the same time, the conveyor belt inside the lower hopper 8 starts. As the conveyor belt shaft rotates, the opening and closing mechanism 13 is driven by the limiting component 12, which causes the baffle 137 to rotate and open the discharge port of the lower hopper 8, allowing the material to enter the funnel 20. The lower side of the funnel 20 is inside the paper box 29, and the magnetic component of the electromagnetic sorting machine 11 is outside the material falling channel, thus magnetically attracting and sorting the falling material. After the conveying is completed, the lower hopper 8 stops running. Through the torsion spring 138 and the upward movement of the funnel 20, it disengages from the transmission of the toothed plate 14 by the paper box 29, causing the baffle 137 to reset itself to avoid the irregular and continuous spillage of material, thus achieving one-time quantitative feeding after weighing.

[0038] Before the funnel 20 receives the material, the cardboard box 29 is first placed on the conveyor 9 for conveying. After the cardboard box 29 is under the funnel 20, the lifting component on the upper side of the conveyor 9 drives the moving frame 19 and the funnel 20 to move down synchronously. After passing through the rack 1 22, gear 21, rack 23, transmission plate 24, moving rod 25 and slide rod 27, the U-shaped block 26 moves down to guide and limit the cardboard box 29, ensuring that the center of the cardboard box 29 is consistent with the center of the lower opening of the funnel 20, so that the lower opening of the funnel 20 moves down and inserts into the inside of the cardboard box 29. At this time, when the material is conveyed by the hopper 8, the gear 1 131 drives the toothed plate 2 14, which applies downward pressure to the toothed plate 2 14 and the vibrating frame 15 through the toothed block 30 and the ball 18, so that the lower side of the vibrating frame 15 contacts the funnel 20 and provides vibration force, so that when the material falls into the inside of the funnel 20, the material residue on the inclined surface of the funnel 20 is reduced.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
