A load-bearing plate is installed on top of the support frame, and the weighing system is mounted on the load-bearing plate. A small storage hopper is supported and connected above the weighing system via a storage hopper bracket. The conveying mechanism's outlet is located above the small storage hopper, and a vibratory feeder outlet is located above the conveying mechanism's inlet. The vibratory feeder outlet is connected to... A vibratory feeder is provided, with a storage hopper fastened above it. A carton conveyor belt is positioned below the load-bearing plate, and electromagnetic sorting machines are installed on both sides of the carton conveyor belt. A discharge hopper is mounted above the electromagnetic sorting machines via a fixed plate, and a discharge cylinder is installed on the fixed plate to facilitate the up-and-down movement of the discharge hopper.

A carton opener is positioned on one side of the carton conveyor belt, and a carton placement trough is positioned on the other side of the carton conveyor belt. A vibrator is connected below the carton placement trough, and a carton sealing and strapping machine is positioned at the other end of the carton placement trough. The existing nail weighing, arranging, and packing system has the following defects: 1. The conveying mechanism is a lifting conveyor belt.

[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] like Figure 1 As shown, a nail magnetic arrangement and boxing production line includes a nail feeding device 1, a nail magnetic boxing device 2, and a nail packaging device 3.

[0032] like Figures 1 to 3As shown, the nail feeding device 1 includes a hopper 11, a magnetic lifting mechanism 12, and a weighing mechanism 13 in sequence according to the material conveying direction. The bottom of the hopper 11 is equipped with a vibration mechanism 111, and the hopper 11 continuously discharges material through vibration; the discharge port of the hopper 11 gradually narrows and connects with the input end of the magnetic lifting mechanism 12, and several sorting baffles 112 are provided at the discharge port of the hopper 11 to prevent the nail material from getting stuck. The magnetic lifting mechanism 12 includes an active conveying roller 124, a passive conveying roller 125, a motor driving the active conveying roller 124, and a lifting belt 121 sleeved between the active conveying roller 124 and the passive conveying roller 125. Baffles 122 are provided on both sides of the lifting belt 121, located on both sides of the conveyor frame to prevent nail materials from falling from one side during transport. Several magnets 14 are provided on the back of the lifting belt 121 along its length. The magnets 14 are fixed to a chain mechanism 15 and move cyclically with the chain mechanism 15 and the lifting belt 121. The magnets 14 remain relatively stationary with respect to the lifting belt 121, thus magnetizing the surface of the lifting belt 121. The lifting belt 121 includes an input section 1211, a lifting section 1212, and an output section 1213. The lifting section 1212 forms an acute angle with the horizontal direction, and the output section 1213 is horizontally positioned. The input section 1211 and the lifting belt 1212 are connected in series. The inclination angles of sections 1212 are the same. The magnet 14 is located on the back of both the input section 1211 and the lifting section 1212. When the nail material is lifted to the output section 1213, the magnet 14 no longer attracts the nail material, and the nail material is horizontally conveyed on the output section 1213, facilitating the final discharge of the nail material. The input section 1211 is equipped with a feeding hopper that connects to the hopper 11. The feeding hopper is funnel-shaped, allowing the incoming nail material to be temporarily stored inside. The lifting belt 121 continuously lifts the nails... Material is carried away; the chain mechanism includes a first chain arranged opposite each other, a passive sprocket group, a driving sprocket group, and a motor driving the driving sprocket group. The magnet 14 is located between the two first chains, and the end of the magnet 14 is fixed to the chain through a connecting seat. The driving sprocket group drives the driving conveyor roller 124 through a second chain. The magnet 14 and the lifting belt 121 move synchronously in a cyclic motion. The magnet 14 generates a magnetic field on the lifting belt 121 of the input section 1211 and the lifting section 1212. The weighing mechanism 13 includes a weighing hopper located at the end of the lifting belt 121, a discharge plate located at the discharge port of the weighing hopper, and a discharge cylinder that drives the discharge plate to flip.Nail feeding device principle: The nail material in the hopper 11 is conveyed to the input end of the magnetic lifting mechanism 12 by vibration. Since the surface of the lifting belt 121 is magnetic, the nail material is attracted after falling on the surface of the lifting belt 121. The nail material is lifted and conveyed with the lifting belt 121. After the nail material is conveyed to the end of the lifting belt 121, it falls into the weighing hopper of the weighing mechanism 13. When the weighing reaches the preset value, the lifting belt 121 stops conveying, and the unloading cylinder drives the unloading plate to flip and open the unloading port. The nail material in the weighing hopper is unloaded and enters the nail magnetic packing device 2 through the transition hopper.

[0033] like Figures 4 to 6As shown, the nail magnetic packing device 2 includes a horizontally arranged conveyor belt 25, a hopper 23 located above the packing station of the conveyor belt 25, a lifting drive mechanism 22 for driving the hopper 23 to rise and fall, a carton forming mechanism 26 located at the input end of the conveyor belt 25, and an electromagnet mechanism 24 located on both sides of the packing station of the conveyor belt 25. The hopper 23 comprises, from top to bottom, a receiving section 231, a transition section 232, and a sorting section 233. The receiving section 231 has a notch on one side, through which the output end of the laterally inclined transition hopper 21 extends into the receiving section 231. Weighed nail material 29 first passes through the transition hopper, which then feeds the nail material 29 into the receiving section 231. The transition section 232 is a tapered tube, wider at the top and narrower at the bottom, used to transition the nail material 29 from the receiving section 231 to the sorting section 233. The sorting section 233 is a square tube with a diameter smaller than the inner diameter of the cardboard box 27, allowing it to be inserted into the cardboard box 27 from above, ensuring the nail material 29 can completely enter the cardboard box 27. The lifting drive mechanism 22 includes a bracket 221 for fixing the hopper 23 and a lifting cylinder 222 connected to the bracket 221. After the hopper 23 descends, the electromagnet mechanism 24 is located on both sides of the square tube, causing a magnetic field to be generated on both sides of the square tube. The electromagnet mechanism 24 includes an iron plate 241 and a main unit 242 that magnetizes the iron plate 241. The conveyor belt 25 is provided with blocking mechanisms 28 on both sides behind the packing station. The blocking mechanism 28 includes a baffle and a blocking cylinder that drives the baffle. The baffle is used to position the carton 27 so that the carton 27 can be accurately stopped at the packing station. The principle of the magnetic nail packing device: The cardboard box forming mechanism 27 forms the folded cardboard into a box and feeds it into the input end of the conveyor belt 25. The conveyor belt 25 transports the box to the packing station and then stops. The lifting drive mechanism 22 picks up and sends the hopper 23 downward, so that the sorting part 233 at the lower end of the hopper 23 is inserted into the cardboard box 27. The electromagnet mechanisms 24 on both sides of the packing station are energized and generate a magnetic field. The nail material 29 is weighed and poured into the hopper 23. The nail material 29 falls freely from top to bottom to the sorting part. When the nail material 29 is inside the magnetic field, it is attracted to the opposite sides of the square tube and is basically arranged horizontally. After the position of the nail material 29 is basically determined, the electromagnet mechanism 24 is turned off. After the nail material 29 loses the magnetic field, it falls freely into the carton 27 again. At this time, the nail material 29 has been basically sorted. The lifting drive basically drives the sorting part 233 to rise and leave the carton 27. The conveyor belt 25 transports the carton 27 containing the nail material 29 to the nail packaging device 3.

[0034] like Figure 7 , 8As shown, the nail packaging device 3 includes, in sequence according to the material conveying direction, a nail replenishing mechanism 31, a replenishing vibrating conveyor mechanism 32, and a carton sealing mechanism 33. The nail replenishing mechanism 31 is equipped with a checkweighing station, which is connected to the output end of the nail magnetic packing device. The nail replenishing mechanism 31 includes a conveyor 312, a checkweigher 311 located at the bottom of the conveyor 312, and a replenishing vibrating plate 313 located above the conveyor 312. After the carton enters the conveyor 312, the checkweigher 311 weighs the carton, which can detect the insufficient weight, and then converts the weight into the number of missing nails, and finally transmits the information to the replenishing vibrating plate 313. The supplementary vibratory conveying mechanism 32 includes a vibratory frame 321, a conveying roller assembly 322 mounted on the vibratory frame 321 and connected to the conveyor 312, and a vibratory motor 324 connected to the conveying roller assembly 322. The input end of the conveying roller assembly 322 is connected to the output end of the conveyor 312, and the output end of the conveying roller assembly 322 is connected to the input end of the carton sealing mechanism 33. The conveying direction of the conveying roller assembly 322 is the same as that of the conveyor 312, and the conveying direction of the conveying roller assembly 322 is perpendicular to that of the carton sealing mechanism 33. The 322 is connected to the vibrating frame 321 by a spring 323. After the vibrating motor 324 is started, it drives the conveying roller group 322 to vibrate. The conveying roller group 322 is powered and can convey the carton during the vibration process. Side baffles are provided on both sides of the conveying roller group 322. The output end of the conveying roller group 322 is provided with a cylinder pushing mechanism 325 facing the carton sealing mechanism 3. The side baffles can ensure that the vibrating carton will not fall. When the carton is conveyed to the end, the vibration and conveying stop, and the cylinder pushing mechanism 325 pushes the carton into the carton sealing mechanism 33. The nail packaging device 3 also includes a robotic arm 34, a placement worktable 35, a roller conveyor mechanism 36, and a wrapping film mechanism 37. The sealed cartons are automatically conveyed to the robotic arm's gripping area. After the cartons are in place, the robotic arm automatically picks up the cartons filled with nail materials and places them orderly on the pallet. The placement can be set according to the required positions, such as how many layers to place and how many cartons per layer. After the cartons are placed orderly on the pallet, the roller conveyor mechanism conveys the pallet of cartons to the wrapping film mechanism. The wrapping film mechanism automatically wraps a layer of transparent stretch film around the cartons on the pallet to ensure that the cartons on the pallet will not become loose or fall off.The nail packaging device operates as follows: After being weighed and packed by the magnetic packing device 2, the nail material passes through the nail replenishing mechanism 31, the replenishing vibration conveying mechanism 32, and the carton sealing mechanism 33 in sequence. After the carton 27 enters the conveyor belt from the conveyor belt into the conveyor 312, the checkweigher 311 weighs the carton 27. If the weight of the carton 27 does not reach the preset value, the replenishing vibration plate 313 is activated, which feeds the nail material into the carton 27 until the weight of the carton 27 reaches the preset value. Under the action of the conveyor 312, the carton 27 enters the conveyor roller group 322 of the replenishing vibration conveying mechanism 32. The vibration motor 324 is started, and the conveyor roller group 322 vibrates and conveys the carton 27. The nail material inside the carton is reorganized during the vibration process. Finally, the carton enters the carton sealing mechanism 33 for sealing.
