Description

Technical Field

[0001] This application relates to the field of bulk packaging technology, specifically to bulk material packaging devices. Background Technology

[0002] Bulk material packaging equipment is used to pack materials into bags. Existing vertical packaging machines cut the packaged bags with a cutting device, and the bags containing the materials fall directly onto a conveyor belt. However, this traditional packaging equipment has some problems when handling fragile, easily damaged, easily scattered, or easily spilled items. For example, when packaging potato chips, the packaged chips may break after falling onto the conveyor belt. Or, when packaging self-tapping screws, the packaged self-tapping screws may easily cause damage to the packaging bag when falling onto the conveyor belt. Or, when packaging electrical components, the electrical components may easily be damaged after falling onto the conveyor belt. Therefore, this application provides a bulk material packaging device to overcome the shortcomings of the prior art. Summary of the Invention

[0003] The purpose of this application is to provide a bulk material packaging device in order to solve the problems mentioned in the background art.

[0008] A conveying mechanism, installed on the support frame and located below the turntable, is used to convey packaged bags;

[0009] A feeding mechanism is installed on the storage box. The rotating disk has an execution area and a waiting area. When one of the storage boxes is in the execution area, the other storage box is in the waiting area. During the process of the storage box moving from the execution area to the waiting area, the storage box will pass through the conveying mechanism and the feeding mechanism to place the packaging bag inside the storage box on the conveying mechanism.

[0010] Furthermore, the conveying mechanism includes a conveyor belt assembly mounted on a support frame. The feed end of the conveyor belt assembly is located below the execution area and the waiting area. The bottom and top of the storage box are both open. The unloading mechanism includes a support plate slidably inserted into the storage box for placing packaged bags. The bottom of the support plate has a vertically constructed execution rod for contacting the feed end of the conveyor belt assembly. A return spring is installed between the execution rod and the storage box.

[0011] Furthermore, the support plate is inclined and the actuator is located at the lowest end of the support plate. A guide rod is constructed on the side of the actuator near the highest end of the support plate. The guide rod slides through the storage box, and the reset spring is sleeved on the guide rod.

[0012] Furthermore, one end of the storage box is eccentrically mounted on the rotating disk via a rotating shaft, and a balancing mechanism acting on the storage box is installed on the support frame. When the rotating disk rotates, the balancing mechanism keeps the storage box in a horizontal state at all times.

[0013] Furthermore, the balancing mechanism includes a connecting plate mounted on the support frame, on which two guide ring plates are concentrically constructed, and a column rod located between the two guide ring plates is rotatably mounted on one side of the storage box, the column rod being tangent to the two guide ring plates.

[0014] Furthermore, the hot melt cutting mechanism includes a second hot melt plate and a movable frame vertically slidably mounted on the support frame. A first hot melt plate is slidably mounted inside the movable frame. Slots are provided on opposite sides of both the first and second hot melt plates. A cutting blade is slidably mounted in the slot of the second hot melt plate. Both ends of the cutting blade are located on the outside and are mounted with movable seats that are slidably inserted into the movable frame. A return spring is installed between the movable seat and the second hot melt plate. A transmission component is installed on the movable frame for driving the second hot melt plate and the movable seat to move closer or further apart.

[0015] Furthermore, the transmission assembly is rotatably mounted on the movable frame with a first rotating rod. Both free ends of the first rotating rod are hinged to hinge rods, and the free ends of the two hinge rods are respectively hinged to the movable seat and the first hot-melt plate. A second rotating rod is rotatably mounted on the movable frame. Both free ends of the second rotating rod are hinged to connecting rods. One connecting rod is hinged to the movable seat, and the other connecting rod is hinged to a sliding plate. The sliding plate is horizontally slidably mounted on the movable frame, and an electric push rod for driving the sliding plate to move is mounted on the movable frame.

[0016] Furthermore, the driving assembly includes a rotating plate rotatably mounted on the support frame. A groove is formed on one side of the rotating plate along its length, and a slider is slidably mounted in the groove. An elastic telescopic rod is installed between the slider and the rotating plate. An arc-shaped toothed plate is mounted on the slider. A driven gear for meshing with the arc-shaped toothed plate is mounted on the rotating disk. A wedge block is slidably mounted on the support frame. A return spring is installed between the wedge block and the support frame. The inclined surface of the wedge block is used to contact one end of the arc-shaped toothed plate, and the other end of the arc-shaped toothed plate is constructed as an inclined surface for contacting one side of the wedge block. A linkage assembly acting on the rotating plate is mounted on the support frame. When the slider moves, the rotating plate is rotated by the linkage assembly. An elastic positioning rod is mounted on the support frame. Two positioning holes for inserting the elastic positioning rod are eccentrically formed on the rotating disk. The two positioning holes are distributed in a circular array.

[0017] Furthermore, the linkage assembly includes a transmission rod rotatably mounted on a support frame, a bevel gear assembly installed between the transmission rod and the rotating plate, a transmission frame horizontally slidably mounted on the support frame, a drive groove vertically slidably opened on the transmission frame, a sliding plate slidably mounted in the drive groove, a drive gear mounted on the transmission rod, and a drive rack meshing with the drive gear mounted on the transmission frame.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0032] Example 1

[0033] like Figures 1-4As shown, the bulk material packaging device proposed in Embodiment 1 of this application includes a support frame 1. A feeding mechanism 10 and a packaging mechanism 2 are installed on the top of the support frame 1. Both the feeding mechanism 10 and the packaging mechanism 2 are existing internal structures of vertical packaging machines. The feeding mechanism 10 is used for distributing bulk materials and for controlling the amount of bulk materials entering the packaging bag. The packaging mechanism 2 is an existing structure for packaging tapes and also includes;

[0034] The hot melt cutting mechanism 3 is mounted on the support frame 1 and located below the packaging mechanism 2. It is used for hot melting and cutting packaging bags.

[0035] The feeding mechanism 4 includes a rotating disk 401 installed on the support frame 1. Two storage boxes 402 are installed on the rotating disk 401 for storing packaged bags. The support frame 1 is equipped with a drive assembly 403 for driving the rotating disk 401 to rotate. When the packaged bags are cut by the hot melt cutting mechanism 3, the bottom of the packaging bags is supported by the storage boxes 402, thus providing support for the packaging bags.

[0036] The conveying mechanism 6 is installed on the support frame 1 and located below the rotating disk 401. It is used to convey the packaged bags. When the rotating disk 401 is rotated by the drive component 403, the storage box 402 will also rotate. Finally, the packaged bags in the storage box 402 will be placed on the conveying mechanism 6.

[0037] The feeding mechanism 5 is installed on the storage box 402. The rotating disk 401 has an execution area and a waiting area. When one of the storage boxes 402 is in the execution area, the other storage box 402 is in the waiting area. Figure 2As shown, the storage box 402 located directly below the packaging mechanism 2 is in the execution area, while the other storage box 402 is in the waiting-to-execute area. During the movement of the storage box 402 from the execution area to the waiting-to-execute area, it passes through the conveying mechanism 6 and is placed onto the conveying mechanism 6 by the unloading mechanism 5. When the hot-melt cutting mechanism 3 cuts the packaging bag, the storage box 402 in the execution area is in contact with the bottom of the packaging bag to be cut. After being cut, the packaging bag is located inside the storage box 402. When the hot-melt cutting mechanism 3 is resetting and preparing for the next hot-melt cutting, the drive component 403 drives the rotating disk 401 to rotate, moving the storage box 402 in the execution area towards the waiting-to-execute area. During the rotation, the storage box 402 containing the packaging bag approaches the conveying mechanism 6. The unloading mechanism 5 places the packaging bag in the storage box 402 onto the conveying mechanism 6. The storage box 402, which was initially located in the waiting area, will move to the execution area to wait for the next use. Compared with the prior art, when the hot melt cutting mechanism 3 cuts the packaged packaging bag, the storage box 402 will hold the cut packaging bag. Then, the drive component 403 will cause the rotating disk 401 to rotate. The rotation of the rotating disk 401 will move the storage box 402 containing the packaging bag onto the conveying mechanism 6. With the help of the unloading mechanism 5, the packaging bag in the storage box 402 will be placed onto the conveying mechanism 6, thus achieving better results when packaging fragile, easily damaged, and easily spilled items.

[0038] like Figure 1 , Figure 2 and Figure 5As shown, in Embodiment 1, the conveying mechanism 6 includes a conveyor belt assembly mounted on the support frame 1. The feed end of the conveyor belt assembly is located below the execution area and the waiting area. The conveyor belt assembly is an existing belt conveyor. In this embodiment, the belt conveyor is horizontally arranged. The storage box 402 has openings at both the bottom and top. The unloading mechanism 5 includes a support plate 501 slidably inserted into the storage box 402, which is used to place packaged bags. That is, the top of the support plate 501 is used to support the packaging bags. The bottom of the support plate 501 has a vertically constructed execution rod 502 for contacting the feed end of the conveyor belt assembly. A return spring 503 is installed between the execution rod 502 and the storage box 402. When the storage box 402 in the execution area has a packaged bag, the rotation... The rotation of the rotating disc 401 causes the packaging bag located in the execution area to rotate to the waiting area. During this process, the storage box 402 passes through the belt conveyor, and the actuator 502 contacts the feed end of the belt conveyor, thereby pushing the actuator 502 to move. The movement of the actuator 502 indirectly drives the support plate 501 to move, causing the support plate 501 to move out of the storage box 402. This allows the material in the storage box 402 to be placed on the conveyor belt of the belt conveyor. As the storage box 402 continues to rotate, the actuator 502 will slowly detach from the belt conveyor. The return spring 503 will reset the actuator 502, thereby causing the support plate 501 to move and reset, completing one unloading action. This achieves automated unloading and is convenient to use.

[0039] like Figure 5 As shown, in Embodiment 1, the support plate 501 is inclined and the actuator 502 is located at the lowest end of the support plate 501. A guide rod 504 is constructed on the side of the actuator 502 near the highest end of the support plate 501. The guide rod 504 slides through the storage box 402. The reset spring 503 is sleeved on the guide rod 504. The inclined design of the support plate 501 ensures that when the cut packaging bag falls into the support plate 501, the packaging bag is at the lowest end of the support plate 501. Thus, when the support plate 501 is opened, the support plate 501 will tilt and move upward, making it easier for the packaging bag to fall from the support plate 501 into the belt conveyor, preventing the packaging bag from getting stuck in the storage box 402.

[0040] Example 2

[0041] Embodiment 2 of this application optimizes the movement of the storage box 402 based on Embodiment 1.

[0042] like Figure 2 and Figure 5As shown, in Embodiment 2, one end of the storage box 402 is eccentrically mounted on the rotating disk 401 via a rotating shaft. A balancing mechanism 7 acting on the storage box 402 is installed on the support frame 1. When the rotating disk 401 rotates, the balancing mechanism 7 keeps the storage box 402 horizontal. When the storage box 402 rotates from the execution area to the waiting area, the rotation angle of the storage box 402 is 180 degrees, and it rotates in an arc. As the storage box 402 rotates from the execution area to the waiting area, it gradually approaches the feed end of the belt conveyor. After the actuator 502 contacts the belt conveyor, the lowest point of the support plate 501 contacts the conveying surface of the belt conveyor. Thus, as the storage box 402 continues to rotate, the actuator 502 causes the support plate 501 to tilt and move upwards. Because the bottom of the packaging bag is also located at the lowest point of the support plate 501, the bag... The bottom of the bag will contact the conveyor surface of the belt conveyor, so that the bag is close to the conveyor surface of the belt conveyor, causing the support plate 501 to open. As the support plate 501 opens, the bag falls onto the belt conveyor. At this time, the storage box 402 continues to move and slowly moves away from the belt conveyor. The return spring 503 will cause the support plate 501 to slowly move back to its original position. After the storage box 402 moves to a certain height, the bag completely passes through the bottom opening of the storage box 402 and enters the belt conveyor. During the process of the actuator 502 opening and closing, the bag has already fallen onto the belt conveyor. The feeding speed is fast, and the balancing mechanism 7 keeps the storage box 402 horizontal when the rotating disk 401 rotates, effectively preventing the bag inside the storage box 402 from falling out when the rotating disk 401 rotates, and making it easier for the bag inside the storage box 402 to enter the belt conveyor.

[0043] In Example 2, as Figure 2 and Figure 3 As shown, the balancing mechanism 7 in Embodiment 2 includes a connecting plate 704 mounted on the support frame 1. Two guide ring plates 705 are concentrically constructed on the connecting plate 704. A column 706 located between the two guide ring plates 705 is rotatably mounted on one side of the storage box 402. The column 706 is tangent to the two guide ring plates 705. When the support plate 501 rotates, the column 706 forces the storage box 402 to rotate within the two guide plates, so as to keep the storage box 402 in a horizontal state. This balancing mechanism 7 occupies little space, is easy to install, and has a simple structure.

[0044] Example 3

[0045] This application's third embodiment further discloses a hot melt cutting mechanism 3, based on embodiments one and two.

[0046] like Figure 4, Figure 7 and Figure 8 As shown, in embodiment three, the hot melt cutting mechanism 3 includes a second hot melt plate 303 and a movable frame 301 vertically slidably mounted on the support frame 1. Specifically, a hydraulic rod can be installed on the support frame 1, with one end connected to the movable frame 301 to drive the movable frame 301 to move. A first hot melt plate 302 is slidably mounted inside the movable frame 301. Slots 304 are provided on opposite sides of the first hot melt plate 302 and the second hot melt plate 303. A cutting blade 305 is slidably mounted in the slots 304 within the second hot melt plate 303 for cutting. The blade 305 has two ends located externally and is fitted with movable seats 306 that are slidably inserted into the movable frame 301. A return spring 307 is installed between the movable seat 306 and the second hot melt plate 303. A transmission component 8 is installed on the movable frame 301 to drive the second hot melt plate 303 and the movable seat 306 to move closer or further apart. That is, when the packaging tape passes through the first hot melt plate 302 and the second hot melt plate 303, and when it is necessary to seal and pack the packaging tape, the transmission component 8 will cause the first hot melt plate 302 and the movable seat 306 to move closer or further apart. 06. As the first hot melt plate 302 and the second hot melt plate 303 approach and adhere to each other, they seal the packaging tape. At this time, the moving base 306 and the second hot melt plate 303 continue to move. Because the cutting blade 305 slides between itself and the second hot melt plate 303, the cutting blade 305 extends from the slot 304 in the second hot melt plate 303, cuts the packaging tape, and then enters the slot 304 in the first hot melt plate 302. At this time, the return spring 307 is in a compressed state. When the first hot melt plate 302 and... When the second hot melt plates 303 move away from each other, the return spring 307 resets, and the hot melted packaging tape forms a packaging bag that falls into the storage box 402. This eliminates the need for an additional drive unit to move the cutting blade 305. When the first hot melt plate 302 and the second hot melt plate 303 approach each other, the hot melt sealing and cutting are completed, further improving packaging efficiency. The vertical movement of the moving frame 301 can adjust the cutting position according to the user's needs, thereby enabling the sealing and cutting of packaging bags of different shapes and improving applicability.

[0047] like Figure 4 and Figures 8-10As shown, in Embodiment 3, the transmission assembly 8 is rotatably mounted on the movable frame 301 with a first rotating rod 801. Both free ends of the first rotating rod 801 are hinged to hinge rods 802, which are respectively hinged to the movable seat 306 and the first hot-melt plate 302. A second rotating rod 803 is rotatably mounted on the movable frame 301, with both free ends of the second rotating rod 803 hinged to connecting rods 804. One connecting rod 804 is hinged to the movable seat 306, and the other connecting rod 804 is hinged to a sliding plate 805. The sliding plate 805 is horizontally slidably mounted on the movable frame 301. The movable frame 301 is equipped with a mechanism for driving the sliding mechanism. The electric push rod 806 moves the plate 805. That is, when the electric push rod 806 moves, the sliding plate 805 moves. Because the sliding plate 805 is hinged to the connecting rod 804, the second rotating rod 803 will rotate. When the second rotating rod 803 rotates, it will cause the moving seat 306 to move through another connecting rod 804. When the moving seat 306 moves, it will cause the first rotating rod 801 to rotate through the hinge rod 802. The rotation of the first rotating rod 801 will cause the first hot melt plate 302 to move through another hinge. At this time, the first hot melt plate 302 and the moving seat 306 will move closer to each other, thereby completing the hot melt cutting.

[0048] Example 4

[0049] Embodiment 4 of this application discloses a drive component 403 based on Embodiment 3, which rotates the rotating disk 401 and links the hot melt cutting mechanism 3 with the drive component 403.

[0050] like Figures 4-7As shown, in embodiment four, the drive assembly 403 includes a rotating plate 4031 rotatably mounted on the support frame 1. A groove 4032 is provided on one side of the rotating plate 4031 along its length. A slider 4033 is slidably mounted in the groove 4032. An elastic telescopic rod 4034 is installed between the slider 4033 and the rotating plate 4031. The elastic telescopic rod 4034 includes a sleeve mounted on the rotating plate 4031. A sleeve rod is slidably inserted into the sleeve. A connecting spring is installed between the sleeve and the sleeve rod. The sleeve rod is connected to the slider 4033. This serves a resetting function. An arc-shaped toothed plate 4035 is mounted on the slider 4033, and a driven gear 4036 for meshing with the arc-shaped toothed plate 4035 is mounted on the rotating disk 401. A wedge-shaped block 4037 is slidably mounted on the support frame 1, and a return spring 4038 is installed between the wedge-shaped block 4037 and the support frame 1. The inclined surface of the wedge-shaped block 4037 is used to contact one end of the arc-shaped toothed plate 4035, and the other end of the arc-shaped toothed plate 4035 is also constructed as an inclined surface, which is used to contact one side of the wedge-shaped block 4037. A function is also provided on the support frame 1. The linkage assembly 9 of the rotating plate 4031 causes the rotating plate 4031 to rotate when the sliding plate 805 moves. An elastic positioning rod 4039 is mounted on the support frame 1. Two positioning holes 40310 for inserting the elastic positioning rod 4039 are eccentrically formed on the rotating disk 401. The two positioning holes 40310 are arranged in a circular array. When the sliding plate 805 moves, causing the first hot-melt plate 302 and the second hot-melt plate 303 to approach each other, the linkage assembly 9 causes the rotating plate 4031 to rotate. When the rotating plate 4031 rotates, it drives the arc-shaped toothed plate 4035 to rotate. At this time, the inclined surface of the arc-shaped toothed plate 4035 will contact the plane of the wedge block 4037, thereby causing the arc-shaped toothed plate 4035 to move. The arc-shaped toothed plate 4035 will then move along the inclined surface to the side of the wedge block 4037 away from the driven gear 4036. Because of this offset, the arc-shaped toothed plate 4035 does not mesh with the driven gear 4036 during rotation, causing the arc-shaped toothed plate 4035 to move to the right side of the driven gear 4036 (e.g., ...). Figure 4 (Refer to the previous text). At this time, the arc-shaped toothed plate 4035 is no longer in contact with the wedge block 4037, so the arc-shaped toothed plate 4035 will move and reset through the elastic telescopic rod 4034. When the sliding plate 805 moves from another direction, causing the first hot melt plate 302 and the second hot melt plate 303 to move away from each other, the arc-shaped toothed plate 4035 meshes with the driven gear 4036, thereby driving the driven rotating disk 401 to rotate. When the arc-shaped toothed plate 4035 moves, it will contact the inclined surface of the wedge block 4037, so the wedge block 4037 will move into the support frame 1 until the arc-shaped toothed plate 4035 is no longer in contact with the wedge block 4037, at which point it will extend through the return spring 4038. At this time, the arc-shaped toothed plate 4035 is located to the left of the drive gear 905 (e.g., ...). Figure 4(Refer to the above) The specific elastic positioning rod 4039 and elastic telescopic rod 4034 have similar structures. The sleeve is installed on the support frame 1, and the sleeve rod is slidably inserted in the sleeve. The outer end of the sleeve rod is hemispherical, and the rotating disk 401 has two hemispherical positioning holes 40310, so that the rotating disk 401 rotates 180 degrees each time, preventing the rotating disk 401 from rotating too much due to inertia. In this way, after the first hot melt plate 302 and the second hot melt plate 303 are attached, the packaging bag falls, and the rotating disk 401 will not rotate. When the first hot melt plate 302 and the second hot melt plate 303 move away from each other, in preparation for the next packaging and cutting, the rotating disk 401 will rotate 180 degrees through the linkage component 9. Therefore, the material initially located in the execution area will move to the waiting execution area. During this process, the material in the storage box 402 is also unloaded, and the storage box 402 located in the waiting execution area moves to the execution area to receive the packaging bag. The overall operation is highly continuous and more convenient to use.

[0051] like Figure 4 and Figure 7 As shown, in embodiment four, the linkage component 9 includes a transmission rod 901 rotatably mounted on the support frame 1. A bevel gear assembly 902 is installed between the transmission rod 901 and the rotating plate 4031. The bevel gear assembly 902 consists of two meshing bevel gears, one of which is mounted on the rotating shaft of the rotating plate 4031, and the other bevel gear is mounted on the transmission rod 901. A transmission frame 903 is horizontally slidably mounted on the support frame 1. A drive groove 904 is vertically slidably opened on the transmission frame 903. A sliding plate 805 is slidably mounted in the drive groove 904. Thus, when the moving frame 301 moves vertically, the sliding plate 805 will move within the drive groove 904, which not only does not affect the movement of the moving frame 301. The sliding plate 805 can still drive the transmission frame 903 to move when it moves. A drive gear 905 is installed on the transmission rod 901, and a drive rack 906 that meshes with the drive gear 905 is installed on the transmission frame 903. That is to say, when the sliding plate 805 moves horizontally, it will cause the transmission frame 903 to move horizontally, thereby driving the rack 906 to move. Since the drive rack 906 meshes with the drive gear 905, the movement of the drive rack 906 will cause the drive gear 905 to rotate, indirectly driving the transmission rod 901 to rotate. At this time, when the rotating rod rotates, it will cause the rotating plate 4031 to rotate through the bevel gear assembly 902, thereby controlling the rotation angle of the arc-shaped toothed plate 4035.

[0052] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
