Description

Technical Field

[0001] This utility model relates to an optical image sorting machine, and in particular to a material discharge and packaging device for the sorting machine. Background Technology

[0002] Based on the optical image sorting machine, a sorting and packaging integrated machine is formed, which can eliminate the manual transfer part and reduce labor costs. However, the material fed in during sealing will interfere with the bottom sealing component. Utility Model Content

[0003] In view of the technical problems existing in the background art, the present utility model aims to provide a material discharge packaging device for a screening machine, which is designed to control the size of the material passage gap by lifting the partition. When the partition is lowered, it blocks the material and avoids the material from continuing to be conveyed and interfering with the bottom sealing component during sealing.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: The discharge packaging device of this screening machine includes a guiding mechanism, a packaging mechanism, a boxing mechanism, and a lifting conveyor belt. The guiding mechanism includes an infeed guide plate, an outlet conveyor belt, and an outlet guide plate. The outlet conveyor belt connects the infeed guide plate and the outlet guide plate. Both the infeed guide plate and the outlet guide plate are inclined. The outlet end of the infeed guide plate is equipped with a lifting baffle, and the baffle forms a material passage gap with the outlet end of the infeed guide plate. The packaging mechanism includes an unwinding shaft, a bag-making hopper, and a side-sealing assembly. The bag-making hopper is located below the discharge end of the discharge guide plate. The bag-making hopper has a connected inlet and outlet. The side sealing assembly is located on one side of the bag-making hopper. The conveyor wheel assembly and the bottom sealing assembly are sequentially arranged below the bag-making hopper. The boxing mechanism includes a first conveyor roller assembly. The lifting conveyor belt is inclined and has trays spaced on it. The receiving end of the lifting conveyor belt is located below the bag-making hopper, and the discharge end of the lifting conveyor belt is located above the first conveyor roller assembly.

[0005] In this scheme, qualified materials fall into the guiding mechanism and are conveyed by the guiding mechanism into the unsealed packaging bag at the packaging mechanism. Before sealing, the partition descends to block the material. After sealing, the packaging bag with material falls onto the lifting conveyor belt due to gravity. The packaging bag falls into the box on the first conveyor roller group due to gravity. After the box is packed, the first conveyor roller group conveys the packed box to the left, and the new empty box arrives below the material drop end of the lifting conveyor belt.

[0006] Preferably, the side sealing assembly includes a matching heat-sealing plate and a heat-sealing base plate, both of which are movable left and right and extend vertically.

[0007] In this solution, the heat-sealing plate and the heat-sealing base plate are pressed together to heat-seal both sides of the packaging bag.

[0008] Preferably, the bottom sealing assembly includes a cooperating hot cutting blade and a hot cutting base plate, both of which are movable back and forth and extend in the left and right direction.

[0009] In this solution, the hot cutting blade and the hot cutting base plate are pressed together, forming a new bottom of the packaging bag while sealing it. The cut packaging bag falls due to gravity.

[0010] Preferably, the packaging mechanism is mounted on a machine platform, and rollers are provided below the machine platform.

[0011] In this solution, the machine can move freely, allowing qualified products to be directly packed into boxes.

[0012] Preferably, the feed end of the feed guide plate is equipped with a discharge nozzle and a photoelectric sensor. The photoelectric sensor is connected to the controller via a signal, and both the discharge nozzle and the partition are connected to the controller via a control connection.

[0013] In this scheme, a photoelectric sensor detects the material and the controller counts it. Once the set value is reached, the controller controls the baffle to descend, which enables quantitative injection.

[0014] Preferably, the feed guide plate is equipped with baffles on both sides.

[0015] In this design, after the partition descends, the baffle, the feed guide plate, and the partition can form a storage cavity.

[0016] Preferably, the packing mechanism further includes a second conveying roller group parallel to the first conveying roller group, the second conveying roller group rotating in the opposite direction to the first conveying roller group, and a pusher plate connecting the second conveying roller group and the first conveying roller group, the pusher plate being movable back and forth.

[0017] In this scheme, the second conveyor roller group transports empty boxes, and the pusher plate pushes the empty boxes onto the first conveyor roller group. The box packing mechanism has a compact structure and continuous box packing.

[0018] Preferably, the discharge guide plate is provided on both sides, and the guide plates gradually move closer together along the conveying direction.

[0019] In this design, the material in contact with the guide plate will move towards the center and fall accurately into the feed inlet of the bag-making hopper.

[0020] The beneficial effects of this utility model are as follows: Qualified materials fall into the guiding mechanism, which then transports them to the unsealed packaging bag at the packaging mechanism. Before sealing, a partition descends to block the material. After sealing, the packaging bag containing the material falls onto the lifting conveyor belt due to gravity. The packaging bag then falls into the box on the first conveyor roller group due to gravity. After packing, the first conveyor roller group transports the packed box backward, and a new empty box reaches below the material drop end of the lifting conveyor belt. Therefore, this utility model has substantial features and progress compared to the prior art. Attached Figure Description

[0030] See appendix Figures 1-3 In this embodiment, a material discharge packaging device for a screening machine includes a guiding mechanism 1, a packaging mechanism 6, a boxing mechanism 9, and a lifting conveyor belt 11. The guiding mechanism 1 includes an infeed guide plate 2, an outfeed conveyor belt 3, and an outfeed guide plate 4. The outfeed conveyor belt 3 connects the infeed guide plate 2 and the outfeed guide plate 4. Both the infeed guide plate 2 and the outfeed guide plate 4 are inclined. The outfeed end of the infeed guide plate 2 is equipped with a lifting baffle 5, which forms a material passage gap with the outfeed end of the infeed guide plate 2. The infeed end of the infeed guide plate 2 is equipped with an outfeed nozzle 14 and a photoelectric eye. The photoelectric eye is signal-connected to a controller. The outfeed nozzle 14 and the baffle 5 are both control-connected to the controller. Baffles 15 are provided on both sides of the infeed guide plate 2, and guide plates 18 are provided on both sides of the outfeed guide plate 4. The guide plates 18 gradually converge along the conveying direction.

[0031] The packaging mechanism 6 includes an unwinding shaft 7, a bag-making hopper 8, a side sealing assembly, a conveyor wheel assembly, and a bottom sealing assembly. The packaging mechanism 6 is mounted on a machine platform, with rollers 13 located below the machine platform. The bag-making hopper 8 is positioned below the discharge end of the discharge guide plate 4, and has a connected inlet and outlet. The side sealing assembly is positioned on one side of the bag-making hopper 8, and includes a matching heat-sealing plate and a heat-sealing bottom plate. Both the heat-sealing plate and the heat-sealing bottom plate are movable left and right, and both extend vertically. The conveyor wheel assembly and the bottom sealing assembly are sequentially positioned below the bag-making hopper 8. The bottom sealing assembly includes a matching hot-cutting blade and a hot-cutting bottom plate, both of which are movable back and forth, and both extend horizontally.

[0032] The packing mechanism 9 includes a first conveyor roller group 10, an inclined lifting conveyor belt 11, and pallets 12 spaced apart on the lifting conveyor belt 11. The receiving end of the lifting conveyor belt 11 is located below the bag making hopper 8, and the dropping end of the lifting conveyor belt 11 is located above the first conveyor roller group 10.

[0033] In this embodiment, a photoelectric eye (not shown in the figure) senses qualified materials. The controller counts based on the photoelectric eye signal and controls the discharge nozzle 14 to move. The material feed guide 2 falls onto the discharge conveyor belt 3, and then along the discharge guide 4 from the unsealed packaging bag at the bag making hopper 8. When the controller count reaches the set value, the controller controls the partition 5 to descend, the hot cutting knife and the hot cutting bottom plate press together, the packaging bag is sealed and cut off, and falls onto the lifting conveyor belt 11 due to gravity, and then falls into the box located below the discharge end of the lifting conveyor belt 11 due to gravity.

[0034] After sealing, the unwinding shaft 7 actively unwinds the bag, and the conveyor wheel set cooperates to bring the bag opening to the bottom sealing assembly. Due to tension, the film continues to surround the bag making hopper 8, and the heat sealing plate and heat sealing bottom plate press and heat seal the side of the packaging bag.

[0035] The number of packaging bags can be obtained by counting the number of times the packaging bags are sealed. The number of packaging bags that have fallen out of the box can be determined. After a certain number of packaging bags have fallen out of the box, the first conveyor roller group 10 rotates to transport the box to the left. The new empty box reaches the bottom of the lifting conveyor belt 11. Among them, the screening machine has mature technology for counting materials and is not limited to setting up photoelectric eyes for sensing at the discharge station; the unwinding shaft 7 unwinds the film and surrounds it outside the bag making hopper 8; the packaging mechanism 6 is a mature technology and is not limited to this; the clamping and heat sealing functions can also be separated so that the bag body is clamped and kept stable when the material is discharged.

[0036] See appendix Figure 1 , 4 The packing mechanism 9 also includes a second conveying roller group 16 parallel to the first conveying roller group 10. The rotation direction of the second conveying roller group 16 is opposite to that of the first conveying roller group 10. A pusher plate 17 is connected between the second conveying roller group 16 and the first conveying roller group 10. The pusher plate 17 is movable back and forth.

[0037] In this embodiment, the first conveyor roller group 10 rotates, and a new empty box reaches below the material drop end of the lifting conveyor belt 11. The pusher plate 17 moves forward and pushes the empty box on the second conveyor roller group 16 to the empty position of the first conveyor roller group 10. The second conveyor roller group 16 rotates, and a new empty box reaches in front of the pusher plate 17. The discharge of the box with packaging bag on the first conveyor roller group 10 and the replenishment of the empty box on the second conveyor roller group 16 can be done manually or by setting up a robot.

[0038] The above description represents the preferred embodiment of this utility model. It should be noted that the protection scope of this utility model is not limited thereto. For those skilled in the art, various improvements, modifications, or equivalent substitutions can be made without departing from the equivalent inventive concept disclosed in this utility model, and these modifications and substitutions are also considered to be within the protection scope of this utility model.
