Description

Technical Field

[0001] This invention relates to the field of packaging equipment technology, and in particular to a fully automatic packaging machine. Background Technology

[0002] Parts packaging is an important process to protect parts from damage during transportation, storage, or sale. Here is a basic parts packaging process: Assess Part Characteristics: First, understand the part's size, weight, material, and fragility. This will determine the required packaging materials and methods. Select Appropriate Packaging Materials: Choose appropriate packaging materials based on the part's characteristics, such as cartons, plastic boxes, anti-static bags, bubble wrap, foam boards, fillers (such as newspaper, foam granules, etc.), tape, and labels. Cleaning and Inspection: Before packing, ensure the parts are clean and undamaged. For mechanical parts, remove oil and dust; for electronic parts, ensure there is no risk of electrostatic discharge. Protective Measures: For fragile or precision parts, wrap them with bubble wrap, foam boards, or specialized shock-absorbing materials for extra protection. Packaging: Carefully place the parts into the packaging materials. Ensure the parts do not move within the packaging to reduce impact and vibration during transport. Sealing: Seal the cartons or plastic boxes with tape to ensure the integrity of the packaging. Before sealing the box, label it with the parts' model, quantity, production date, and other necessary information. Marking and Tracking: Clearly mark the packaging with information such as destination, recipient, number of pieces, weight, and volume for tracking and management during transport. Packing Inspection: After packing, conduct a final inspection to ensure the packaging meets shipping requirements and is free of omissions or errors. Storage or Transportation: Place the packed parts in an appropriate location; if transporting, arrange according to the shipping plan.

[0003] Currently, existing packaging machines typically bag parts directly. When the parts in the bag reach the specified weight, the bag is heat-sealed. Before packaging, the bag surface needs to be coded to specify the specifications and model of the parts. However, during the coding and weighing process, dust and other impurities on the bag surface may affect the quality of the coding, and iron filings and other impurities on the weighing platform may affect the accuracy of the weighing, thus affecting the quality of each bag of parts, resulting in uneven quality and packaging that fails to meet requirements. Based on this, a fully automatic packaging machine is proposed. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art where dust and other impurities on the bag surface affect the quality of coding during the coding and weighing process, and iron filings and other impurities on the weighing platform affect the accuracy of weighing, thus affecting the quality of each bag of parts, resulting in uneven quality and packaging that fails to meet requirements. Therefore, a fully automatic packaging machine is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fully automatic packaging machine includes a storage base, a guide frame, and a packaging box. It also includes: a lifting frame installed on top of the storage base, with a lifting plate installed inside the lifting frame, an electromagnetic plate installed on one side of the lifting plate, and a transfer frame rotatably connected to the top of the lifting plate; a fixed frame fixedly connected to the top of the packaging box, a storage slot opened at the free end of the fixed frame, rotating rollers installed on the side wall of the fixed frame, a marking machine installed inside the fixed frame, and marking blocks installed on top of the marking machine on the fixed frame.

[0007] To facilitate the lifting of parts, preferably, a storage box is also included, which is fixedly connected to the top of the storage base. A discharge pipe is fixedly connected to the side of the storage box near the lifting frame. A servo motor is fixedly connected to one side of the lifting frame. The output end of the servo motor is fixedly connected to the lifting plate through a transmission assembly.

[0008] Furthermore, the output end of the servo motor is fixedly connected to a drive sprocket and a driven sprocket, which are connected by a chain. The lifting plate is installed on the adjacent side of the chain, and the driven sprocket is rotatably connected inside the lifting frame.

[0009] To facilitate the adjustment and release of the parts, preferably, a collection hopper is installed on the top of the guide frame, and box doors are installed on both sides of the guide frame. A vibrating guide plate is installed inside the guide frame, and the collection hopper is located on top of the vibrating guide plate. A transfer box is installed on the guide frame, and a box cover is installed at the discharge end of the transfer box. The output end of the vibrating guide plate is connected to the input end of the transfer box.

[0010] Furthermore, the box cover is driven by an electric cylinder, and the electric cylinder is installed on both sides of the transfer box.

[0011] Furthermore, a packing tube is fixedly connected to one side of the packing box, and a roll bag frame is fitted over the outside of the packing tube. The roll bag frame is fixedly connected to the packing box, and a guide roller is installed on the fixed frame. The input end of the packing tube is connected to the output end of the transfer box, and a control panel is installed on one side of the packing box.

[0012] Furthermore, a heat-sealing plate is installed on the side of the packing box near the packing tube, and a transport wheel is installed on the side of the packing box near the packing tube and at the bottom of the heat-sealing plate. The heat-sealing plate and the transport wheel are located at the discharge end of the packing tube, and both the heat-sealing plate and the transport wheel are controlled by a control panel.

[0013] To further heat-seal the packaged bags and clean the markings and weighing plates, a heat-sealing box is fixedly connected to the side of the packaging box near the bottom of the packaging tube. Two sets of first cylinders are fixedly connected inside the heat-sealing box. A heat-sealing frame is fixedly connected to the output end of each set of first cylinders. A connecting frame is fixedly connected to the output end of each set of first cylinders. A fourth cylinder is mounted on the connecting frame. A cutter is fixedly connected to the output end of the fourth cylinder. The cutter can slide freely within the heat-sealing frame. A connecting pipe is fixedly connected to one side of one heat-sealing frame. A cleaning air frame is fixedly connected to the end of the connecting pipe away from the heat-sealing frame. A cleaning air hole is opened on one side of the cleaning air frame. A connecting pipe is fixedly connected to the bottom of the other heat-sealing frame. An air blowing head is fixedly connected to the bottom of the connecting pipe.

[0014] Furthermore, the cleaning air frame is fixedly connected to the fixed frame and located between the marking machine and the marking block, with the cleaning air hole facing the marking machine.

[0015] Furthermore, a fixed frame is fixedly connected to the side of the packing box near the heat-sealing box and at the bottom of the heat-sealing box. A third cylinder is fixedly connected to the inner bottom of the fixed frame. A weighing plate is installed on the top of the third cylinder. A second cylinder is rotatably connected to the bottom of the weighing plate. The air blowing head is located on the top of the weighing plate. The end of the second cylinder away from the weighing plate is rotatably connected to the packing box.

[0016] Compared with the prior art, the present invention provides a fully automatic packaging machine, which has the following beneficial effects:

[0017] 1. This fully automatic packaging machine uses a cutter that slides back and forth within a heat-sealing frame. This causes hot air within the frame to escape through cleaning vents and act on the outer surface of the packaging bag. This process heats the outer surface of the bag and removes dust and other impurities. Heating the bag improves its smoothness, which helps the ink adhere better. At the same time, it prevents the bag from drying too slowly, which would affect production efficiency and the durability of the labels, thus ensuring the quality and clarity of the labels.

[0018] 2. This fully automatic packaging machine uses a cutter that slides back and forth within a heat-sealing frame. This causes hot air from the heat-sealing frame to act on a weighing plate through an air blower. During this process, the air blower pushes the sealed packaging bag towards the free end of the weighing plate, allowing the sealed packaging bag to be quickly discharged from the weighing plate. It also cleans the weighing plate by blowing air, preventing impurities such as iron filings from remaining on the weighing plate and affecting the weighing accuracy of the parts inside the packaging bag. This ensures that the weight of the parts in each packaging bag is within the specified range, guaranteeing the accuracy of the packaging.

[0019] 3. This fully automatic packaging machine uses a cutter that slides inward within the heat-sealing frame to allow cold air from the outside to enter the frame and cool the cutter. This allows the cutter to quickly detach from the heat-sealed bag, preventing the bag from sticking to the cutter and hindering its automatic detachment, thus reducing packaging efficiency.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0031] Example:

[0032] Reference Figures 1-4 An automatic packaging machine includes a storage base 1, a guide frame 12, and a packaging box 18. It also includes a lifting frame 4 installed on top of the storage base 1, a lifting plate 9 installed inside the lifting frame 4, an electromagnetic plate 10 installed on one side of the lifting plate 9, and a transfer frame 11 rotatably connected to the top of the lifting plate 9. Furthermore, it includes a storage box 2 fixedly connected to the top of the storage base 1, a discharge pipe 3 fixedly connected to the side of the storage box 2 near the lifting frame 4, a valve installed inside the discharge pipe 3, a servo motor 5 fixedly connected to one side of the lifting frame 4, the output end of the servo motor 5 fixedly connected to the lifting plate 9 via a transmission assembly, a drive sprocket 6 and a driven sprocket 8 fixedly connected to the output end of the servo motor 5, the drive sprocket 6 and the driven sprocket 8 connected via a chain 7, the lifting plate 9 installed on the adjacent side of the chain 7, and the driven sprocket 8 rotatably connected inside the lifting frame 4.

[0033] In use, first pour the parts into the storage box 2. When the transfer frame 11 is at the bottom of the discharge pipe 3, open the valve in the discharge pipe 3 to allow the parts in the discharge pipe 3 to enter the transfer frame 11. When the specified mass is reached in the transfer frame 11, close the valve in the discharge pipe 3. Then, start the servo motor 5 to rotate the drive sprocket 6, which in turn rotates the driven sprocket 8 via the chain 7. The operation of the chain 7 will cause the lifting plate 9 to move upward until the transfer frame 11 reaches the top of the guide frame 12. At this point, the electromagnetic plate 10 will be de-energized, preventing it from controlling the transfer. The frame 11 is attracted, and at this time, the transfer frame 11 will rotate in the direction of the guide rack 12 under the gravity of the parts inside, pouring the parts into the guide rack 12. Then the transfer frame 11 will automatically reset, and the electromagnetic plate 10 can be activated again to attract the transfer frame 11. Then the servo motor 5 reverses, and the chain 7 will move downward under the action of the active sprocket 6 and the driven sprocket 8, which will cause the lifting plate 9 to drive the transfer frame 11 downward until the transfer frame 11 reaches the bottom of the discharge pipe 3. Then the discharge pipe 3 is opened again, and the transfer and lifting of the parts are achieved by repeating this process.

[0034] It realizes automatic feeding of parts, and the feeding amount can be automatically controlled to prevent the parts from piling up in the guide rack 12, which would prevent the iron filings and other impurities contained in the parts from being shaken off.

[0035] Reference Figures 1-3 A collection hopper 13 is installed on the top of the guide frame 12, and box doors 14 are installed on both sides of the guide frame 12. A vibrating guide plate 15 is installed inside the guide frame 12, and the collection hopper 13 is located on the top of the vibrating guide plate 15. A transfer box 16 is installed on the guide frame 12, and a box cover 17 is installed at the discharge end of the transfer box 16. The output end of the vibrating guide plate 15 is connected to the input end of the transfer box 16. The box cover 17 is driven by an electric cylinder, and the electric cylinder is installed on both sides of the transfer box 16.

[0036] The transfer frame 11, which reaches the top of the guide rack 12, will pour the parts inside into the collection hopper 13. After passing through the collection hopper 13, the parts enter the vibrating guide plate 15. The vibrating guide plate 15 shakes off the iron filings and other impurities in the parts. The parts that enter the vibrating guide plate 15 will enter the transfer box 16 one by one under the vibration of the vibrating guide plate 15 until the amount of parts in the transfer box 16 is about to reach the mass of one package. At this time, the electric cylinder will work to open the box cover 17, and the parts in the transfer box 16 will be automatically discharged.

[0037] This method effectively removes residual iron filings and other impurities from the parts, ensuring the cleanliness of the packaged parts.

[0038] Reference Figures 1-3 , Figures 4-8A fixed frame 23 is fixedly connected to the top of the packing box 18. A storage slot 24 is provided at the free end of the fixed frame 23. A rotating roller 25 is installed on the side wall of the fixed frame 23. A marking machine 26 is installed inside the fixed frame 23. A marking block 27 is installed on top of the marking machine 26. A packing tube 20 is fixedly connected to one side of the packing box 18. A roll bag frame 28 is fitted over the packing tube 20 and fixedly connected to the packing box 18. A guide roller 30 is installed on the fixed frame 23. The input end of the packing tube 20 is connected to the output end of the transfer box 16. A control panel 19 is installed on one side of the packing box 18. A heat-sealing plate 21 is installed on the side of the packing box 18 near the packing pipe 20. A transport wheel 22 is installed on the side of the packing box 18 near the packing pipe 20 and at the bottom of the heat-sealing plate 21. The heat-sealing plate 21 and the transport wheel 22 are located at the discharge end of the packing pipe 20. Both the heat-sealing plate 21 and the transport wheel 22 are controlled by the control panel 19. A heat-sealing box 29 is fixedly connected to the side of the packing box 18 near the packing pipe 20 and at the bottom of the packing pipe 20. Two sets of first cylinders 31 are fixedly connected inside the heat-sealing box 29. The output ends of the two sets of first cylinders 31 are fixed. A heat-sealing frame 32 is connected to the heat-sealing frame 32. A connecting bracket 33 is fixedly connected to the output end of each of the two sets of first cylinders 31. A fourth cylinder 44 is mounted on the connecting bracket 33. A cutter 34 is fixedly connected to the output end of the fourth cylinder 44. The cutter 34 can slide freely within the heat-sealing frame 32. A connecting pipe 35 is fixedly connected to one side of one heat-sealing frame 32. A cleaning air frame 36 is fixedly connected to the end of the connecting pipe 35 away from the heat-sealing frame 32. A cleaning air hole 37 is opened on one side of the cleaning air frame 36. A connecting pipe 38 is fixedly connected to the bottom of the other heat-sealing frame 32. An air blowing head 3 is fixedly connected to the bottom of the connecting pipe 38. 9. The cleaning air frame 36 is fixedly connected to the fixed frame 23 and is located between the labeling machine 26 and the labeling block 27. The cleaning air hole 37 is set directly opposite the labeling machine 26. The packing box 18 is fixedly connected to the side near the heat sealing box 29 and at the bottom of the heat sealing box 29 by a fixed frame 40. The bottom of the fixed frame 40 is fixedly connected to a third cylinder 43. The top of the third cylinder 43 is equipped with a weighing plate 41. The bottom of the weighing plate 41 is rotatably connected to a second cylinder 42. The air blowing head 39 is set on the top of the weighing plate 41. The end of the second cylinder 42 away from the weighing plate 41 is rotatably connected to the packing box 18.

[0039] When packaging parts, the roller frame containing unsealed packaging bags is first placed on the storage trough 24. Then, the unsealed packaging bags pass sequentially through the guide roller 30 and rotating roller 25, positioning them between the labeling machine 26 and the labeling block 27. The labeling machine 26 then labels the unsealed packaging bags. After labeling, the bags pass through the guide roller 30 into the gap between the roll bag frame 28 and the packaging tube 20, with the opening of the unsealed bag positioned between the heat-sealing plate 21 and the transport wheel 22. The heat-sealing plate 21 seals both sides of the unsealed bag, which then wraps around the packaging tube 20. The rotating transport wheel 22 then conveys the unsealed bags downwards sequentially. When the quantity of parts in the transfer box 16 reaches the required weight for one packaging, they pass through the packaging tube 20 into the unsealed packaging bags. The packaging bags are then placed on the weighing plate 41, which weighs the bags. During weighing, the electric cylinder will intermittently extend and retract slightly, causing the lid 17 to open intermittently, allowing the parts in the transfer box 16 to be discharged one by one. They then enter the packing bag through the packing tube 20. When the weight of the parts in the packing bag reaches the specified weight, the electric cylinder will close the lid 17, preventing the transfer box 16 from discharging the parts. At this time, the first cylinder 31 will work, causing the heat sealing frame 32 to move inward simultaneously to heat seal the packing bag. After heat sealing, the fourth cylinder 44 will work, causing the cutter 34 to move inward simultaneously to cut the heat-sealed packing bag, causing the packing bag to fall onto the weighing plate 41. The inward sliding of the cutter 34 will cause the hot air generated in the heat sealing frame 32 to be discharged through the connecting pipe 35 and the connecting pipe 38. The connecting pipe 35 will conduct the hot air to the cleaning air frame 36, and blow it onto the label surface of the packing bag through the cleaning air hole 37.

[0040] Heating the outer surface of the packaging bag and removing dust and other impurities from it improves its smoothness, which helps the ink adhere better to the bag. At the same time, it prevents the packaging bag from drying too slowly due to low temperature, which would affect production efficiency and the durability of the label, thus ensuring the quality and clarity of the label.

[0041] The airflow discharged through the connecting pipe 38 will be blown onto the surface of the weighing plate 41 through the air blowing head 39;

[0042] During this process, the air blowing head 39 pushes the sealed packaging bag to slide towards the free end of the weighing plate 41, so that the sealed packaging bag can be quickly discharged from the weighing plate 41, and the weighing plate 41 can be cleaned by blowing air to prevent iron filings and other impurities from remaining on the weighing plate 41 from affecting the weighing accuracy of the weighing plate 41 on the parts inside the packaging bag, thereby ensuring that the quality of the parts in each packaging bag is within the specified range and ensuring the accuracy of packaging.

[0043] When the packing bag falls onto the weighing plate 41, the second cylinder 42 will be activated to move the free end of the weighing plate 41 downwards, thus emptying the packing bag from the weighing plate 41.

[0044] After the heat sealing and cutting is completed, the fourth cylinder 44 will retract, causing the cutter 34 to slide outward, drawing outside cold air into the cleaning air frame 36 through the cleaning air hole 37, and then into the heat sealing frame 32 through the connecting pipe 35. At the same time, outside cold air will also enter the connecting pipe 38 through the air blower 39, and finally enter the heat sealing frame 32.

[0045] This achieves cooling of the cutter 34 inside the heat-sealing frame 32, allowing the cutter 34 to quickly detach from the heat-sealed packaging bag, preventing the heat-sealed packaging bag from sticking to the cutter 34, which would prevent the packaging bag from automatically detaching and affect packaging efficiency.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
