Description

Technical Field

[0001] This application relates to the field of powder product plastic box receiving technology, specifically to an automated device for powder product plastic box receiving. Background Technology

[0002] After powder products are manufactured, they typically need to be packaged in plastic boxes for sealing and collection. Traditional collection methods are mostly manual, with workers removing the sealed plastic boxes from the conveyor line and stacking them in certain quantities. This method suffers from problems such as high labor intensity, low efficiency, uneven stacking, and easy damage to the boxes, making it difficult to meet the needs of large-scale automated production.

[0003] Currently, while some automated equipment can convey and stack plastic boxes, their receiving mechanisms are often complex. Switching between layered and stacked modes requires replacing parts or making cumbersome adjustments, making it difficult to flexibly adapt to different receiving requirements. Furthermore, existing receiving devices, when achieving multi-layer automatic layering, rely heavily on sensors, cylinders, or motors to drive the support components layer by layer, resulting in high system costs, complex control logic, and increased failure rates. Additionally, the disassembly and maintenance of the layered support structure is inconvenient, making it difficult to quickly adjust the number of layers or perform cleaning.

[0004] Therefore, there is an urgent need for an automated powder product plastic box receiving device that is simple in structure, can quickly switch between layered and stacked modes, can automatically achieve layered material receiving without additional power, and is easy to maintain.

[0005] Application content

[0006] The purpose of this application is to provide an automated device for receiving plastic boxes containing powdered products.

[0007] In the first aspect, the automated powder product plastic box receiving device provided in this application adopts the following technical solution: it includes a support frame, a servo motor, a positioning drive disk, a discharge stratification mechanism, and a plastic box body. The positioning drive disk is installed on the top of the support frame, and a servo motor is fixed at the bottom of the positioning drive disk. A discharge stratification mechanism is provided at the bottom right end of the positioning drive disk. The discharge stratification mechanism includes a fixed block, a cylinder, a movable seat, a fixed seat, a first slide groove, a swing arm, a second slide groove, a stratification placement mechanism, and a guide plate. The top of the fixed block is fixed to the positioning drive disk, and a cylinder is connected to the bottom of the fixed block. A movable seat is fixed at the right end of the cylinder. The movable seat slides with the inner side of the first slide groove using a sliding shaft. The top of the fixed seat is fixed to the positioning drive disk. A first slide groove is opened in the middle of the fixed seat. A second slide groove is opened at the right end of the swing arm. The swing arm is fixed to the right end of the guide plate. A stratification placement mechanism is provided at the right end of the guide plate.

[0008] By adopting the above technical solution, the support frame, servo motor, positioning drive disk, discharge layering mechanism and plastic box body work together to automatically complete the positioning, layering and discharge of plastic boxes and the collection of materials, thereby improving production efficiency and automation.

[0009] Preferably, a plastic box conveying track is provided at the top right end of the positioning drive disk, an indexing plate is movably connected to the middle of the positioning drive disk, multiple sets of positioning slots are distributed along the circumference of the indexing plate, the bottom of the indexing plate is connected to the output end of the servo motor, one end of the plastic box conveying track is connected to the positioning slot, a plastic box cover conveying track is provided at the rear end of the positioning drive disk, a plastic box cover gripper assembly is provided at the front end of the conveying track, a cover pressing assembly is provided at the right rear end of the positioning drive disk, a pushing assembly is installed at the right end of the positioning drive disk, a powder product discharge assembly is provided at the top left end of the positioning drive disk, and a plastic box body is placed inside the positioning slot.

[0010] By adopting the above technical solution, the plastic box conveyor track orderly feeds the plastic box body into the positioning slot of the indexing plate. With the help of the servo motor driving the indexing plate to rotate intermittently, the powder product filling, plastic box lid conveying, capping and finished product ejection are completed in sequence, realizing fully automatic assembly line operation.

[0011] Preferably, the swing arm has a V-shaped cross-section, and the middle part of the swing arm is movably connected to the inner side of the fixed seat. The lower end of the swing arm is provided with a second sliding groove, and the movable seat adopts a sliding shaft that slides into the inner side of the second sliding groove.

[0012] By adopting the above technical solution, the V-shaped swing arm swings around the fixed seat under the drive of the cylinder. By utilizing the sliding cooperation between the second slide groove and the moving seat, the guide plate can be quickly switched between two states: vertical blocking and horizontal release. The structure is compact and the operation is reliable.

[0013] Preferably, the guide plate is initially placed vertically to block the plastic box body. When the guide plate is set horizontally, the right end of the guide plate is tilted downward and the guide plate is placed on the upper left end of the layered placement mechanism.

[0014] By adopting the above technical solution, the guide plate can block the plastic box body when it is vertical, and can smoothly guide the plastic box body to the layer placement mechanism when it is horizontally tilted, effectively controlling the discharge sequence of the plastic box body and avoiding accumulation or jamming.

[0015] Preferably, there are two sets of emission stratification mechanisms, and the emission stratification mechanisms are arranged opposite each other on the front and rear sides of the emission port at the right end of the positioning drive disk. A conveyor belt assembly is provided at the bottom of the emission stratification mechanism to transport the material on the emission stratification mechanism to the next working area.

[0016] By adopting the above technical solution, the two sets of emission stratification mechanisms are set opposite to each other on the front and rear sides of the emission port, and can operate synchronously to place the plastic box body layer by layer on the conveyor belt assembly, so as to achieve orderly output and facilitate the connection of subsequent processes.

[0017] Preferably, the layered placement mechanism includes a support base, a locking buckle, a threaded rod, a support column, a movable slot, a bottom holding seat, a first movable frame, a linkage holding structure, and a blocking and limiting plate. The top left end of the support base is slidably connected to the locking buckle. The threaded rod is threadedly connected to the left end of the support base, and the right end of the threaded rod is movably connected to the locking buckle. The bottom of the support column is fixed to the support base. The support column has multiple sets of movable slots equidistantly spaced. The bottom holding seat is movably connected to the inner side of the movable slot. The bottom holding seat is fixed to the bottom of the first movable frame. The inner side of the first movable frame is movably connected to the linkage holding structure. The top rear end of the support column is fixed with a blocking and limiting plate for blocking the plastic box body.

[0018] By adopting the above technical solution, the layered placement mechanism utilizes the bottom holding seat and the linkage holding structure to select layered placement or stacking as needed, flexibly adapting to different material receiving requirements, while the blocking and limiting plate prevents the plastic box from falling.

[0019] Preferably, the locking buckle moves synchronously with the threaded rod, and the bottom holding seat protrudes from the right end of the movable groove to support the side wall of the falling plastic box, thereby allowing the plastic boxes to be placed in layers. When the locking buckle moves to the right, it presses down and engages with the left end of the bottom holding seat, causing the bottom holding seat to retract into the inner side of the movable groove, thus preventing it from supporting the falling plastic box and allowing the plastic boxes to be stacked.

[0020] By adopting the above technical solution, the locking buckle moves with the threaded rod. When the locking buckle engages with the bottom holding seat, the bottom holding seat retracts into the movable groove, and the plastic box naturally falls and stacks. When the locking buckle disengages, the bottom holding seat extends to support the plastic box, realizing layered placement. The operation is simple and the switching is convenient.

[0021] Preferably, the locking buckle, threaded rod, support column, movable groove, bottom holding seat, first movable frame, linkage holding structure, and blocking limit plate constitute a support assembly. There are two sets of support assemblies, which are arranged opposite each other on the top left and right sides of the support seat. A gap is provided between the two sets of support columns to allow the plastic box to fall.

[0022] By adopting the above technical solution, the left and right support components are symmetrically arranged to form a falling channel for the plastic box between the two sets of pillars, which together support the two sides of the plastic box to ensure stable placement. Moreover, the linkage holding structure can move step by step and automatically adapt to multi-layer material collection.

[0023] Preferably, the linkage holding structure includes a linkage holding seat, a movable shaft, a linkage rod, a second movable frame, a positioning rod, a first support washer, a pin, a locking nut, and a second support washer. The linkage holding seat is movably connected to the inner side of the movable slot. The linkage holding seat is located at the top of the bottom holding seat. The linkage holding seat is movably connected to the middle of the movable shaft. A linkage rod is provided at the bottom of the movable shaft, and the linkage rod is movably connected to the inner side of the first movable frame by a positioning rod. A second movable frame is fixed to the top left end of the linkage holding seat. A second support washer and a first support washer are provided opposite to each other on the top two sides of the positioning rod. The gasket and the first support gasket are respectively set on the front and rear sides of the first movable frame. The locking nut is threaded with the threaded pattern of the front end of the positioning rod. The rear end of the positioning rod is embedded with a pin. Initially, the linkage holding seat is retracted into the inner side of the movable groove. When a plastic box is placed on the bottom holding seat at the bottom of the linkage holding seat, the bottom holding seat pushes the linkage rod upward through the first movable frame, thereby causing the linkage rod to swing the linkage holding seat, so that the linkage holding seat protrudes from the right end of the movable groove to support the next set of plastic boxes. This process is repeated, and another set of linkage holding structures located at the upper end of this set of linkage holding structures repeats the above operation.

[0024] By adopting the above technical solution, after the plastic box is placed on the bottom holding seat, the linkage rod is pushed up by the first movable frame, which in turn causes the upper-level linkage holding seat to swing out and support the newly falling plastic box. In this way, the layers are linked one by one, and automatic layer stacking can be achieved without additional power. The structure is ingenious and energy-saving.

[0025] Preferably, the linkage holding structure is provided in multiple sets, and each set of linkage holding structures is connected together by a linkage rod and a second movable frame.

[0026] By adopting the above technical solution, the multi-group linkage holding structure is connected in series with the second movable frame by linkage rods to form a hierarchical transmission chain. Each level can automatically respond to the support status of the next level, realizing sequential layered placement from bottom to top. It has strong expandability and adapts to the material collection needs of different heights.

[0027] In summary, this application includes the following beneficial technical effects:

[0028] 1. The guide vane in the stratification mechanism is driven by a cylinder, a moving seat, and a V-shaped swing arm, which can quickly switch between vertical blocking and horizontal release states, allowing the finished product box to smoothly enter the stratification placement mechanism. The stratification placement mechanism adopts a modular bottom holding seat, multiple sets of linked holding structures, and locking buckle components. It achieves automatic stratification support from bottom to top through mechanical linkage: after the next layer supports the box, gravity triggers the upper layer support seat to automatically extend, completing the layer-by-layer placement without additional sensors or power sources. At the same time, the locking buckle can be easily switched to the stacking mode by rotating the threaded rod. This design is compact, reliable, and significantly reduces equipment costs and failure rates.

[0029] 2. The guide plate tilts downwards on the right side during discharge and is precisely placed on the upper left side of the layered placement mechanism, providing a smooth sliding path for the boxes and avoiding impact and damage caused by free fall; the symmetrical pillars, movable slots and blocking limit plates on both sides of the layered placement mechanism ensure that the boxes fall vertically and the force is evenly distributed on both sides. Combined with the retractable holding seat, the boxes are stacked in an orderly and neat manner, effectively preventing tipping, jamming or collision, and ensuring the appearance quality of the finished product;

[0030] 3. The layered placement mechanism, through the cooperation of locking buckles and threaded rods, can quickly switch between layered placement and stacking modes. Users only need simple operation to adapt to different packaging or process requirements. In addition, the linkage holding structure adopts a detachable positioning rod, locking nut and pin design, which can quickly adjust the number of layers or replace parts without disassembling the whole, which is convenient for maintenance and cleaning, and allows for flexible configuration of the receiving height according to the production batch, enhancing the versatility and applicability of the equipment.

[0031] 4. The discharge stratification mechanism is set up in two sets and arranged opposite each other on the front and rear sides of the discharge port. Together with the bottom conveyor belt assembly, the sealed plastic boxes are orderly exported, stacked and automatically transported to the next work area to form a compact receiving unit. The overall structure is reasonably designed, reducing the intermediate manual transfer links, saving production site space and reducing labor intensity, which is conducive to realizing unmanned or minimally manned production.

The middle of the positioning drive disk 3 is movably connected to an indexing disk 32. The indexing disk 32 has multiple sets of positioning grooves distributed along the circumferential direction. The bottom of the indexing plate 32 is connected to the output end of the servo motor 2. One end of the plastic box conveying track 31 is connected to the positioning groove. The rear end of the positioning drive plate 3 is provided with a plastic box cover conveying track 5. The front end of the conveying track 5 is provided with a plastic box cover gripper assembly 6. The right rear end of the positioning drive plate 3 is provided with a cap pressing assembly 7. The right end of the positioning drive plate 3 is equipped with a pushing assembly 8. The top left end of the positioning drive plate 3 is provided with a powder product discharge assembly 9. The inner side of the positioning groove is where the plastic box body 10 is placed. The cross-section of the swing arm 46 is V-shaped, and the middle part of the swing arm 46 is movably connected to the inner side of the fixed base 44. Next, a second sliding groove 47 is provided at the lower end of the swing arm 46. The moving seat 43 is slidably engaged with the inner side of the second sliding groove 47 by means of a sliding shaft. The guide plate 49 is initially placed vertically to block the plastic box body 10. When the guide plate 49 is set horizontally, the right end of the guide plate 49 is tilted downward and the guide plate 49 is placed on the upper left end of the layering placement mechanism 48. There are two sets of the discharge layering mechanism 4. The discharge layering mechanism 4 is arranged opposite to each other on the front and rear sides of the discharge port on the right end of the positioning drive disk 3.

The bottom of the support column 484 is fixed to the support base 481. Multiple sets of movable grooves 485 are equidistantly provided on the support column 484. The bottom holding seat 486 is movably connected to the inner side of the movable groove 485. The bottom holding seat 486 is fixed to the bottom of the first movable frame 487. The linkage holding structure 488 is movably connected to the inner side of the first movable frame 487. A blocking and limiting plate 489 is fixed to the top rear end of the support column 484. 9. A locking buckle 482 is used to block the plastic box body 10. It moves synchronously with the threaded rod 483. The bottom holding seat 486 protrudes from the right end of the movable groove 485, supporting the side wall of the falling plastic box body 10, thus allowing the plastic box body 10 to be placed in layers. When the locking buckle 482 moves to the right, it presses down and engages with the left end of the bottom holding seat 486, causing the bottom holding seat 486 to retract into the inner side of the movable groove 485, preventing it from pressing against the bottom. The falling plastic box body 10 is supported, allowing the plastic box body 10 to be stacked. The locking buckle 482, threaded rod 483, support column 484, movable groove 485, bottom holding seat 486, first movable frame 487, linkage holding structure 488, and blocking limit plate 489 together constitute the support assembly. There are two sets of support assemblies, which are arranged opposite each other on the top left and right sides of the support seat 481. A gap is provided between the two sets of support columns 484 to allow the plastic box body 10 to fall.

[0047] In this application, the linkage holding structure 488 includes a linkage holding seat 4881, a movable shaft 4882, a linkage rod 4883, a second movable frame 4884, a positioning rod 4885, a first support washer 4886, a pin 4887, a locking nut 4888, and a second support washer 4889. The linkage holding seat 4881 is movably connected to the inner side of the movable groove 485. The linkage holding seat 4881 is located at the top of the bottom holding seat 486. The linkage holding seat 4881 is movably connected to the middle of the movable shaft 4882. The bottom of the movable shaft 4882 is provided with a linkage rod 4883, and the linkage rod 4883 is movably connected to the inner side of the first movable frame 487 by a positioning rod 4885. The second movable frame 4884 is fixed to the top left end of the linkage holding seat 4881. The second support washer 4889 and the first support washer 4889 are arranged opposite each other on the top sides of the positioning rod 4885. The first support pad 4886, the second support pad 4889, and the first support pad 4886 are respectively disposed on the front and rear sides of the first movable frame 487. The locking nut 4888 is threadedly engaged with the threaded front end of the positioning rod 4885. The rear end of the positioning rod 4885 is embedded with a pin 4887. Initially, the linkage holding seat 4881 is retracted into the inner side of the movable groove 485. When a plastic box 10 is placed on the bottom holding seat 486 at the bottom of the linkage holding seat 4881, the bottom holding seat 486 pushes the linkage rod 4883 upward through the first movable frame 487, thereby causing the linkage rod 4883 to drive the linkage holding seat 4881 to swing, so that the linkage holding seat 4881 protrudes from the right end of the movable groove 485 to support the next set of plastic box 10. This process is repeated, and another set of linkage holding structures 488 located above this set of linkage holding structures 488 repeats the above operation.

[0048] It should be noted that support frame 1 serves as the base of the entire device, ensuring the structural stability and positional accuracy of the device during operation.

[0049] Servo motor 2 provides precise rotational power to indexing plate 32; it rotates intermittently according to a preset program, driving the plastic box body on the indexing plate through different workstations in sequence, namely powder filling, box lid installation, capping, and discharge, to achieve automated cyclic operation.

[0050] The positioning drive disk 3 has a cavity and guide structure inside to accommodate the indexing disk; on the one hand, it supports the rotation of the indexing disk, and on the other hand, it connects with external devices such as the plastic box conveying track 31 and the discharge layering mechanism 4 to play a positioning and guiding role.

[0051] The discharge stratification mechanism 4 is located at the discharge port on the right end of the positioning drive disk. It is used to export the sealed plastic box body from the positioning groove of the indexing disk and guide it to the stratification placement mechanism 48 through the guide plate 49. This mechanism can realize the orderly discharge of the box body and cooperate with the stratification placement mechanism to complete the stratification or stacking of materials.

[0052] The plastic box conveying track 31 transports the empty plastic box body from the upstream feeding device to the positioning slot of the indexing plate 32 in an orderly manner; the end of the track docks with the positioning slot to ensure that the box body enters the indexing plate smoothly and accurately.

[0053] Indexing plate 32: It rotates intermittently under the drive of a servo motor, and each positioning slot passes through each station in sequence; the shape of the positioning slot matches the outer contour of the plastic box to prevent the box from shifting or falling off during rotation;

[0054] Plastic box lid conveying track 5: conveys the plastic box lids from the feeding device to the picking position of the plastic box lid gripper assembly 6; the track is equipped with guide grooves to ensure that the box lids are arranged in the same direction and with uniform spacing;

[0055] Plastic box lid gripper assembly 6: Installed at the front end of the conveyor track, usually using pneumatic or electric grippers; used to grip a single plastic box lid from the end of the track and accurately place it on the plastic box body that has been filled with powder to complete the pre-closing action;

[0056] Capping assembly 7: Located at the right rear end of the positioning drive disk, it is used to apply pressure to the plastic box with the cap already placed on it, so that the cap and the box body are tightly fastened together to complete the sealing; a pressure cylinder or a rolling mechanism can be used to ensure that the cap is firm and does not damage the box body;

[0057] Pushing component 8: Located at the right end of the positioning drive plate, it cooperates with the discharge stratification mechanism 4; when the plastic box is capped and rotated to the discharge station, the pushing component pushes the plastic box out of the positioning slot of the indexing plate, so that it falls into the guide plate 49 area of ​​the discharge stratification mechanism;

[0058] Powder product discharging component 9: Located at the top left of the positioning drive plate, it is used to fill a fixed amount of powder products, such as metal powder and ceramic powder, into the empty plastic box; it usually includes a hopper, a metering device and a discharge nozzle, which can achieve precise feeding;

[0059] Plastic box body 10: serves as a container for holding powder products; its external dimensions are matched with components such as positioning groove, guide plate 49, and layer placement mechanism 4 to ensure stable transmission, positioning, and stacking on the automatic line;

[0060] The movable seat 43: It connects with the first slide groove 45 and the second slide groove 47 respectively through the sliding shaft to transmit the linear motion of the cylinder to the swing arm 46;

[0061] Fixed seat 44: provides a pivot point for the swing arm and has a first groove to guide the moving seat;

[0062] Swing arm 46: When the moving seat 43 moves back and forth, the swing arm 46 swings around the fulcrum, causing the guide plate 49 to switch between the vertical blocking position and the horizontal release position.

[0063] Deflector plate 49: When initially vertical, it blocks the plastic box body 10; when horizontally tilted, it forms a slide to smoothly guide the box body to the layered placement mechanism 48.

[0064] Layered placement mechanism 48: receives the plastic box 10 falling from the guide plate 49 and can be placed in layers or stacked as needed; its core is to use the linkage holding structure 488 to automatically support the newly falling box step by step without the need for additional power or sensors.

[0065] Support base 481: The base of the layered placement mechanism, used to support components such as support column 484 and locking buckle 482, and to maintain overall stability;

[0066] Locking buckle 482 and threaded rod 483: The two work together to switch between layered / stacked modes; the threaded rod 483 is threaded to the left end of the support base 481 and can move left and right when rotated.

[0067] When the locking buckle moves to the right, its inclined surface or claw presses down on the left end of the bottom holding seat 486, causing it to retract into the movable groove 485, at which point the box falls and stacks.

[0068] When the locking buckle moves to the left, it releases the restriction on the bottom container 486, and the bottom container 486 extends under its own weight to achieve layered placement;

[0069] Support column 484, movable slot 485: The support column 484 is vertically fixed on the support base 481. On its inner side, i.e. the opposite side, multiple movable slots 485 are equally spaced along the height direction. The movable slots 485 are used to install the bottom holding base 486 and the linked holding bases 4881 of each layer. The gap between the two sets of support columns forms the falling channel of the plastic box body 10.

[0070] Bottom holding seat 486, first movable frame 487: The bottom holding seat 486 is installed in the lowest movable slot 485, and its right end can extend or retract; when the bottom holding seat 486 extends, it supports the first plastic box; when it retracts, it allows the boxes to fall and stack.

[0071] Blocking and limiting plate 489: used to limit the backward displacement of the plastic box body 10 when it falls, ensuring that the box body falls vertically into the gap between the two sets of support columns 484 to prevent it from tipping over or getting stuck.

[0072] Movable shaft 4882: connects the linkage holding base 4881 and the linkage rod 4883, so that the linkage rod 4883 can rotate around it;

[0073] Linkage rod 4883: The lower end is connected to the first movable frame 487 of the next level holding seat, namely the bottom holding seat 486 or the lower linkage holding seat, via the positioning rod 4885; when the next level holding seat supports the box and sinks relatively due to gravity, the linkage rod 4883 is pushed upward, thereby causing the current level linkage holding seat to swing outward around the movable axis 4882, protruding from the right end of the movable groove 485, thereby supporting the newly fallen box;

[0074] Second movable frame 4884: used to connect with the upper linkage rod 4883 to realize step-by-step transmission;

[0075] Positioning rod 4885: Passes through the holes on the first movable frame 487 and the second movable frame 4884, serving as a hinge axis;

[0076] First support pad 4886 and second support pad 4889: restrict the axial movement of positioning rod 4885, while ensuring smooth relative rotation between linkage rod 4883 and first movable frame 487;

[0077] Pin 4887: Inserted into the rear end of positioning rod 4885 to prevent the positioning rod from retracting;

[0078] Locking nut 4888: Tightened onto the thread at the front end of positioning rod 4885, together with pin 4887, to fix the axial position of positioning rod 4885;

[0079] Conveyor belt assembly: Located at the bottom of the discharge stratification mechanism 4, it is used to transport the stacked or arranged plastic boxes on the stratification placement mechanism 48 to the next work area, such as the packaging, inspection or palletizing station.

[0080] Example 2: An automated receiving device for plastic boxes of powder products, wherein multiple sets of the linkage holding structure 488 are provided, and each set of linkage holding structure 488 is connected together by a linkage rod 4883 and a second movable frame 4884.

[0081] It should be noted that the linkage holding structure 488 is connected in multiple sets: when there are multiple sets of linkage holding structure 488, the second movable frame 4884 in each set is connected to the linkage rod 4883 of the previous set to form a series transmission chain; after the bottom holding seat 486 of the bottom layer supports the first box, it triggers the extension of the linkage holding seat of the layer above it; after the layer supports the second box, it triggers the extension of the layer above it, and so on, until the top layer;

[0082] Effect: It can automatically achieve sequential layer placement from bottom to top without the need for sensors and additional power; the operation of each set of linked holding structures is independent and reliable, and the overall height can be flexibly designed according to the actual amount of material collected.

[0083] Connection method between multiple sets of linked holding structures: The linkage rod 4883 and the second movable frame 4884 are hinged through parts such as positioning rod 4885, gasket, pin 4887, and locking nut 4888, ensuring that each layer can transmit motion and has a certain degree of rotational freedom to avoid jamming.

[0084] When this device is working, the empty plastic box body 10 is first sent to the positioning slot of the indexing plate 32 in the positioning drive plate 3 by the plastic box conveying track 31; the servo motor 2 drives the indexing plate 32 to rotate intermittently according to the preset program, so that the plastic box body 10 in each positioning slot passes through each station in sequence.

[0085] When the plastic box body 10 rotates to a position below the powder product discharging component 9, the discharging component 9 precisely fills a fixed amount of powder product into the box body; then the indexing plate 32 continues to rotate, sending the box body containing powder to the plastic box cover gripper component 6, the plastic box cover gripper component 6 picks up a single plastic box cover from the plastic box cover conveying track 5 and places it on the box body, completing the pre-covering; then the indexing plate 32 sends the pre-covered box body to a position below the capping component 7, the capping component 7 applies pressure to make the box cover and the box body fit tightly together, completing the sealing;

[0086] The plastic box 10, after being capped, rotates to the discharge station with the indexing plate 32. The push assembly 8 pushes it out of the positioning groove and it falls into the guide plate 49 area of ​​the discharge stratification mechanism 4. In the initial state, the guide plate 49 is placed vertically and acts as a block for the box. When discharge is required, the cylinder 42 is activated, pushing the moving seat 43 to move horizontally along the first slide groove 45. The moving seat 43 cooperates with the second slide groove 47 on the swing arm 46 through the sliding shaft, driving the V-shaped swing arm 46 to swing around the fixed seat 44. This causes the guide plate 49, which is fixed to the swing arm 46, to flip from the vertical position to the horizontal tilted position. The right end of the guide plate 49 tilts downward and rests on the upper left end of the stratification placement mechanism 48. The box then slides smoothly into the stratification placement mechanism 48 along the guide plate 49.

[0087] The layered placement mechanism 48 can be selected for layered or stacked placement as needed. When layered placement is required, the locking buckle 482 is in the left position, and the bottom holding seat 486 extends out of the right end of the movable slot 485 under its own weight or elastic action. After the first box falls into the gap between the two sets of support columns 484, its side wall is supported by the bottom holding seat 486 and stays at the bottom. At this time, the bottom holding seat 486 descends relatively due to supporting the box, and pushes the linkage rod 4883 upward through the first movable frame 487. The linkage rod 4883 drives the linkage holding seat 4881 located on the upper layer to swing outward around the movable axis 4882, so that the linkage holding seat 4881... 81 protrudes from the right end of the movable groove 485; when the second box falls, it is supported by the layer linkage holding seat 4881; similarly, the second box triggers the extension of the upper layer linkage holding seat 4881, and so on, to achieve automatic layer placement from bottom to top; when stacking is required, rotate the threaded rod 483 to move the locking buckle 482 to the right, and the locking buckle 482 presses down on the left end of the bottom holding seat 486, causing it to retract into the movable groove 485, and the box is no longer supported by the bottom holding seat 486 and falls directly onto the lower box, and subsequent boxes are stacked in sequence; the layer placement mechanism 48 is symmetrically arranged on the left and right sides to ensure that the force on both sides of the box is uniform.

[0088] There are two sets of discharge stratification mechanisms 4, which are arranged opposite each other on the front and rear sides of the discharge port, and a conveyor belt assembly is provided at the bottom of them. After the discharge is completed, the conveyor belt assembly will transport the stacked plastic box 10 on the stratification placement mechanism 48 to the next working area to realize automated material collection.

[0089] In the linkage holding structure 488, the positioning rod 4885 passes through the first movable frame 487 and the second movable frame 4884. Its front end is locked by the locking nut 4888 and its rear end is fixed by the pin 4887. When it is necessary to disassemble a certain layer of the linkage holding structure 488, simply unscrew the locking nut 4888 and pull out the pin 4887 to pull out the positioning rod 4885, thereby separating the linkage rod 4883 from the linkage holding seat 4881 of that layer, realizing quick disassembly and assembly, and facilitating maintenance, replacement or adjustment of the number of layers.
