Description

Technical Field

[0001] This invention pertains to packaging machinery, and specifically relates to a top-loading packaging device. Background Technology

[0002] Packaging cartons are widely used for packaging various products, especially medical devices such as pre-filled needles and syringes. Top-loading packaging equipment is used to realize the forming, conveying, filling, sealing and output of packaging cartons, completing the entire process from paper blank forming to finished box output.

[0003] Existing top-loading packaging equipment typically includes a preform storage unit, a preform gripping mechanism, a preform boxing mechanism, a box conveying mechanism, an instruction manual storage unit, an instruction manual boxing mechanism, a material conveying mechanism, a material gripping mechanism, an inner tongue folding mechanism, a box sealing mechanism, and a box output mechanism. This type of packaging equipment has the following problems:

[0004] 1. The paper blank material silo is a single-unit silo for storage and conveying. Material can only be retrieved one paper blank at a time, which affects the retrieval and forming speed. At the same time, the paper blank material silo is generally connected to the whole machine by bolts, which makes it difficult to change the tooling fixtures for paper blanks of different specifications. This delays the time when changing products and affects work efficiency.

[0005] 2. The paper blank gripping mechanism is used to grip packaging box paper blanks in the paper blank material warehouse and place them in a fixed position and angle for subsequent processing equipment to retrieve. Existing gripping mechanisms mostly use servo motors to drive the suction clamps to reciprocate through linkages, resulting in large equipment vibrations; moreover, when the position sensor malfunctions, the mechanism may swing beyond its position, colliding with other mechanism components and causing damage.

[0006] In addition, the existing gripping mechanism frame is usually bolted together, which has poor adjustability; moreover, there are situations in a packaging equipment where multiple materials with different heights are gripped, so the gripping equipment needs to be specifically designed and is not very versatile.

[0007] 3. The paper blank box-forming mechanism includes a single-sheet paper blank gripper mechanism, a glue spraying mechanism, and a single-station paper box forming group, all mounted on the frame. This box-forming mechanism can only fold a single paper blank into a box at a time, resulting in low work efficiency. Moreover, the production process may involve frequent changes in packaging materials and paper blank specifications, requiring the paper blank gripper mechanism to be replaced and adjusted. However, the existing bolt-locking method is not convenient for quick disassembly, affecting production efficiency.

[0008] 4. The inner tongue folding mechanism is used to fold the inner tongues at both ends of the packaging carton to a horizontal position, thereby supporting and protecting the material. The existing folding mechanism uses two symmetrically arranged cylinders that extend and retract simultaneously, pushing the pusher to move horizontally and flatten the inner tongue. This results in significant equipment vibration and affects the service life of the equipment.

[0009] 5. Existing cardboard box sealing mechanisms achieve the folding and sealing operation of cardboard boxes by swinging a lever or oscillating plate. However, this mechanism can only fold and seal cardboard boxes one by one, resulting in low work efficiency. Moreover, after sealing, the front flap of the cardboard box cover is glued to the front of the packaging box, making it difficult for end users to open the box and wasting glue. Summary of the Invention

[0029] As a further preferred embodiment, limit plates are connected to the outer sides of the two support plates by connecting columns. The distance between the two limit plates is matched with the length of the paper blank to be conveyed, which is used to limit the paper blank during conveying. Support blocks are placed between the two limit plates on the two synchronous belt mechanisms. The support blocks follow the synchronous belt mechanisms and are used to block the paper blank to be conveyed from behind.

[0030] As a further preferred embodiment, the paper blank gripping mechanism includes a frame assembly and a suction clamp, and a servo motor and a drive shaft are provided on the frame assembly, with the servo motor and the drive shaft being connected in a transmission manner.

The lower end of the swing arm is hinged to the frame assembly, and the upper end of the swing arm is hinged to the middle of the output arm. A mounting plate is connected between the two output arms, and the suction clamp is fixed to the mounting plate by a thumb-type locking device.

[0032] Crank-connecting rod assemblies are symmetrically connected to both ends of the drive shaft. The outer ends of the connecting rods of the crank-connecting rod assemblies are respectively hinged to the middle of the corresponding swing arms to drive the swing arms to swing back and forth.

[0033] Two control components are symmetrically hinged within the frame assembly. Each control component includes a small swing arm, a long connecting rod, and a short connecting rod. The lower end of the small swing arm is hinged to the frame assembly, and the upper end of the small swing arm is hinged to one end of the long and short connecting rods. The other end of the long connecting rod is hinged to the lower end of the corresponding output arm. The other ends of the two short connecting rods are hinged to the lower part of the two swing arms via a long shaft. These components are used to control the output arms to rotate back and forth as they follow the swing arms, thereby adjusting the angle of the suction clamp.

[0034] As a further preferred embodiment, the suction clamp includes a connecting plate, which is attached to the mounting plate and fixed by the thumb-type locking device; a suction cup frame is fixed on the connecting plate, and multiple suction cup seats are evenly distributed and fixed on the suction cup frame. A baffle and four suction cups arranged in a rectangle are installed on each suction cup seat. The outer ends of the suction cups protrude through the through holes on the baffle and are used to adsorb the paper blank material to be gripped.

[0035] As a further preferred embodiment, the frame assembly includes an inner frame and an outer frame. The servo motor, drive shaft, swing arm assembly, and control assembly are all mounted on the outer frame. The two upright plates of the outer frame are respectively attached to the two sides of the inner frame and fixed to the inner frame by guide strips and clamps located on the outer side of the inner frame. A rotatable adjustment shaft is installed on the inner frame. The two ends of the adjustment shaft pass through the two upright plates of the outer frame and are provided with cams.

[0036] As a further preferred embodiment, the inner frame is formed by two symmetrically arranged connecting seats connected by two connecting shafts, and the outer frame is formed by two upright plates connected by multiple connecting shafts.

[0037] As a further preferred embodiment, the paper box conveying mechanism includes a circular magnetic levitation conveyor line with several trolleys on it. Each trolley is equipped with a paper box fixing clamp to simultaneously receive the paper boxes formed after the paper blank is formed and convey them forward to the next process.

[0038] As a further preferred embodiment, the material conveying mechanism includes two parallel conveyor belts, with several material blocks evenly distributed and fixed on the conveyor belt of each conveyor belt for placing the materials to be packaged.

[0039] As a further preferred embodiment, the material gripping mechanism is located above the material conveying mechanism and the carton conveying mechanism, and includes a spider robot. A suction cup gripper is connected to the lower end of the spider robot's gripper to simultaneously grip a pair of materials and place them into the formed carton.

[0040] As a further preferred embodiment, the inner tongue folding mechanism is mounted between the material conveying mechanism and the carton conveying mechanism via a bracket. It includes a mounting base plate, on which a sliding plate is slidably mounted via two transverse slide rail assemblies. A servo motor is provided on the bottom surface of the mounting base plate in the vertical direction. The output end of the servo motor is connected to the sliding plate via a crank-slider mechanism to drive the sliding plate to intermittently reciprocate along the width direction of the mounting base plate.

[0041] Two connecting plates are slidably mounted on the sliding plate via two longitudinal slide rail assemblies. Drive cylinders are provided near both ends of the sliding plate, and the output ends of the drive cylinders are connected to the corresponding connecting plates to drive the two connecting plates to slide in opposite directions.

[0042] F-type pushers are evenly distributed and fixed on the two connecting plates. One end of each F-type pusher extends to the same side of the two connecting plates.

[0046] As a further preferred option, a paper box turning mechanism is provided on the frame between the paper box conveying mechanism and the paper box output mechanism, which is used to turn the sealed packaging paper box 90 degrees before supplying it to the paper box output mechanism;

[0047] The paper box turning mechanism includes a mounting plate frame, in which a sliding plate is slidably mounted via a linear slide rail assembly. A drive cylinder is provided at the bottom of the mounting plate frame, and the output end of the drive cylinder is fixedly connected to the sliding plate via a connecting frame to drive the sliding plate to reciprocate.

[0048] Multiple rotatable shafts are evenly distributed on the mounting plate. The lower end of the shaft is connected to the sliding plate through a gear and rack assembly. Suction cup seats are fixed on the upper end of the shaft. Suction cups are evenly distributed on the suction cup seats and box trays are fixed thereon. The suction cups are led out from the corresponding through holes of the box trays and are used to adsorb the material packaging boxes onto the box trays.

[0049] As a further preferred embodiment, the carton output mechanism includes a conveyor belt conveying mechanism and a carton gripper mechanism. The carton gripper mechanism is located on the frame above the conveyor belt conveying mechanism and is used to grip the packaged carton after sealing and turning onto the conveyor belt conveying mechanism. The conveyor belt conveying mechanism is arranged longitudinally along the frame and extends from one end of the frame for outputting the packaged carton.

[0050] As a further preferred embodiment, the second structural unit includes an instruction manual storage box and an instruction manual boxing mechanism. The instruction manual boxing mechanism includes an instruction manual gripping mechanism and an instruction manual handle mechanism. The instruction manual gripping mechanism is basically the same in structure as the paper blank gripping mechanism and is used to grip the instruction manuals from the instruction manual storage box and place them at a horizontal angle. The instruction manual handle mechanism has multiple instruction manual handles evenly distributed on it and is used to grip the instruction manuals from the instruction manual gripping mechanism and put them into the formed paper box located on the paper box conveying mechanism.

[0051] The beneficial effects of this invention are:

[0052] 1. Since the paper blank material library includes multiple parallel paper blank conveying mechanisms, it can simultaneously place and convey multiple sets of paper blanks; through the paper blank gripping mechanism located between the paper blank material library and the paper blank boxing mechanism, multiple paper blanks can be gripped and sent to the paper blank boxing mechanism at the same time.

[0053] 2. The paper blank box-forming mechanism includes a paper blank gripper mechanism, a glue spraying mechanism, and a paper box forming mechanism. Multiple cardboard grippers are evenly distributed and mounted on the lower end of the Z-axis slide of the two-axis linear slide of the paper blank gripper mechanism via a mounting frame. Therefore, it can simultaneously grip multiple paper blanks for packaging boxes and sequentially send them to the glue spraying mechanism and the paper box forming mechanism. The glue spraying mechanism includes multiple pairs of first glue guns evenly arranged in a row, with each pair corresponding to the inner tongues at both ends of the paper blank to be formed. Therefore, it can simultaneously spray glue onto the inner tongues at both ends of multiple paper blanks. Furthermore, the paper box forming mechanism, with its multiple evenly distributed forming components, enables the simultaneous automatic box-forming of multiple packaging boxes, resulting in high work efficiency and increased production speed.

[0054] 3. Since multiple cardboard grippers are installed on the two-axis linear slide via mounting brackets and quick-release components, cardboard grippers can be quickly replaced according to the required packaging box blank specifications. They are easy to install and remove, which can improve work efficiency when changing different specifications.

[0055] 4. Since the paper blank box forming mechanism, material gripping mechanism, paper box sealing mechanism and paper box output mechanism are connected in sequence through the paper box conveying mechanism to achieve linkage, the material gripping mechanism can simultaneously grip a pair of materials and put them into the formed paper box, and the paper box sealing mechanism can simultaneously fold and seal the top cover of multiple packaging paper boxes; therefore, it can simultaneously realize the forming, filling and sealing output of multiple paper blanks, resulting in high production efficiency.

[0056] 5. Since the paper blank gripping mechanism drives the drive shaft to rotate continuously via a servo motor, the crank connecting rod assemblies at both ends of the drive shaft can drive the two swing arm assemblies hinged to the frame assembly to swing back and forth, thereby driving the suction clamp located between the two swing arm assemblies to swing back and forth. By connecting the lower end of the output arm of the two swing arm assemblies and the lower part of the swing arm respectively through two control components symmetrically hinged in the frame assembly, the output arm can be controlled to rotate back and forth when following the swing arm to swing back and forth, thereby adjusting the angle of the suction clamp when following the swing arm assembly to swing, thus realizing the gripping and placement of the paper blank material. The structure is compact, the operation is stable, and the operating vibration is small, which can prevent the mechanism from swinging out of position and colliding with other mechanism components, causing damage to other mechanism components.

[0057] 6. The two swing arm assemblies, which are symmetrically hinged to one end of the frame assembly, are connected to the mounting plate. The suction clamp is fixed to the mounting plate by a thumb-type locking device. The suction clamp can be quickly replaced according to different specifications. It is easy to disassemble and assemble, has high replacement efficiency, and is highly versatile.

[0058] 7. Since the inner tongue folding mechanism uses a servo motor connected to the sliding plate via a crank-slider mechanism, it can drive the sliding plate to slide intermittently back and forth along the width direction of the mounting base plate, thereby driving the F-type pushers evenly distributed and fixed on the two connecting plates to extend and insert into both ends of each packaging carton; the two connecting plates are driven to slide in opposite directions by a drive cylinder, and two adjacent F-type pushers are symmetrically arranged and fixed on the two connecting plates respectively. Therefore, under the drive of the connecting plates, two adjacent F-type pushers can move in opposite directions to realize the automatic folding of the inner tongues of multiple packaging cartons, with high working efficiency and smooth operation.

[0059] 8. Because multiple sealing clamps are evenly distributed on the mounting frame of the carton sealing mechanism, two suction cups symmetrically arranged at the front end of the base plate of each sealing clamp can hold the surface of the carton body on one side of the top cover. The folding cylinder arranged between the base plate and the folding pressure plate can drive the folding pressure plate to flip and fold the top cover of the carton. The tongue-pressing cylinder symmetrically arranged on the front vertical plate at the bottom of the folding pressure plate can stick the glued top cover tongue to the other side of the carton body. Therefore, it can realize the automatic folding and sealing of multiple carton top covers at the same time, with high work efficiency. At the same time, the tongue-pressing cylinder can accurately press the glue point of the top cover tongue, which can avoid the problem of the entire front of the carton top cover sticking to the front of the packaging box, causing difficulties for the end user to open the box.

Detailed Implementation

[0116] like Figures 1-6 As shown, the present invention relates to a top-loading packaging device, comprising a frame 16, within which are arranged a paper blank storage 6, a paper blank gripping mechanism 5, a paper blank boxing mechanism, a carton conveying mechanism 1, an instruction manual storage 9, an instruction manual boxing mechanism, a material conveying mechanism 10, a material gripping mechanism 14, an inner tongue folding mechanism 15, a carton sealing mechanism 13, and a carton output mechanism; the paper blank boxing mechanism, instruction manual boxing mechanism, material gripping mechanism 14, carton sealing mechanism 13, and carton output mechanism are sequentially connected and linked through the carton conveying mechanism 1. A controller 17 is cantilevered at the front of the frame 16 for coordinating and controlling the power source operation of each mechanism.

[0117] The frame 16 is divided into four structural units along its longitudinal direction. The paper blank material library 6, the paper blank gripping mechanism 5, and the paper blank boxing mechanism are located in the first structural unit 1601. The instruction manual material library 9 and the instruction manual boxing mechanism are located in the second structural unit 1602. The material conveying mechanism 10, the material gripping mechanism 14, and the inner tongue folding mechanism 15 are located in the third structural unit 1603. The paper box sealing mechanism 13 and the paper box output mechanism are located in the fourth structural unit 1604. The paper box conveying mechanism 1 runs through all four structural units.

[0118] like Figures 7-13As shown, the paper blank storage 6 includes a support frame 601, on which a mounting plate 602 is fixed. Multiple L-shaped brackets 609 are evenly fixed to the mounting plate 602 with screws. A fixing plate 611 is connected to the top plate of each bracket 609 via a thumb-type locking device 610. The fixing plate 611 and the top plate are interlocked by mutually cooperating bosses and grooves. Paper blank conveying mechanisms are fixed to the fixing plates 611. Multiple paper blank conveying mechanisms are arranged in parallel for simultaneously placing and conveying multiple sets of paper blanks. A guide plate 607 is fixed to the support frame 601 above the mounting plate 602. This embodiment uses four brackets and four paper blank conveying mechanisms as an example.

[0119] The support frame 601 includes a movable base 6011 with wheels at each of the four corners of its bottom surface. Two upright plates 6013 are symmetrically fixed to the base 6011 with screws. The two upright plates 6013 are trapezoidal and interconnected by three vertically arranged connecting rods 6012 and three connecting strips 6014. The three connecting strips 6014 are arranged parallel to each other along the hypotenuses of the two upright plates 6013. A fixing plate 611 is fixed between the connecting strips 6014 located in the middle and lower parts with screws. A guide plate 607 is fixed between the connecting strips 6014 located in the upper and middle parts with spring plungers 614 and thumb-type locking devices 613. Two U-shaped blocks 8 are symmetrically fixed to the connecting strips 6014 located in the upper and middle parts, respectively, to facilitate the connection of the spring plungers 614 and the thumb-type locking devices 613.

[0120] The paper blank conveying mechanism includes two support plates 617 that are fixed parallel to both sides of the fixed plate 611 by screws. The support plates 617 are inverted V-shaped with unequal sides and the long side is arranged horizontally. Two synchronous belt mechanisms 603 are provided between the two support plates 617 and connected to a support plate 616. The synchronous belts of the two synchronous belt mechanisms 603 pass through rectangular grooves provided on the support plate 616 to support and convey the paper blanks 619 to be used. The two synchronous belt mechanisms 603 share a drive shaft 6031, a driven shaft 6032 and a secondary shaft 6033. The secondary shaft is located at the corner of the support plate 617, and the two ends of the drive shaft 6031 are mounted on the front end of the support plate 617 by bearings.

[0121] A swing arm 622 is mounted in the middle of the drive shaft 6031 via a one-way bearing. A connecting plate 624 is fixed between the bottoms of two support plates 617. A cylinder 623 is hinged on the connecting plate 624. The output end of the cylinder 623 is hinged to the lower end of the swing arm 622 to drive the two synchronous belt mechanisms 603 to step.

[0122] Limiting plates 615 are fixedly connected to the outer sides of the two support plates 617 by two connecting columns 618. The distance between the two limiting plates 615 is matched with the length of the paper blank 619 to be conveyed, which is used to limit the paper blank during conveying. Supporting blocks 612 are placed on the two synchronous belt mechanisms 603 between the two limiting plates 615 with a gap fit. The supporting blocks 612 follow the synchronous belt mechanism 603 to step and block the paper blank to be conveyed from behind.

[0123] Multiple irregularly shaped guide holes are evenly distributed on the guide plate 607, each corresponding to a paper blank conveying mechanism, with the front part of the paper blank conveying mechanism passing through the corresponding guide hole. Two guide strips 605 are fixed to the left, right, and top sides of each guide hole on the guide plate 607 via L-shaped brackets 604, used for guiding the paper blank during conveying. Each guide strip 605 has a screw hole at its front end with a ball screw 606 screwed in to prevent the paper blank from falling.

[0124] Two photoelectric sensors 621 are fixed to the front side of the connecting strip 6014 at the top, corresponding to the middle of each guide hole, by a sensor bracket 620. These sensors are used to detect whether there is a shortage of material on each paper blank conveying mechanism and transmit the information to the controller 17.

[0125] like Figure 13 As shown, a connecting assembly is fixed on the base 6011 at the lower end of the support frame 601. The connecting assembly includes a fixing block 625 and a connecting block 626. A connecting shaft 628 is fixed on the fixing block 625. One end of the connecting shaft 628 is provided with an annular groove and is inserted into the connecting block 626. A spring plunger 627 is screwed into the connecting block 626. The positioning post at the lower end of the spring plunger 627 is inserted into the annular groove for fixing and connecting the frame assembly of the paper blank gripping mechanism 5.

[0126] During operation, four sets of paper blanks are placed on the synchronous belt of each paper blank conveying mechanism, and the moving support block blocks the paper blanks to be conveyed from behind. The control cylinder 623 reciprocates; when cylinder 623 extends, it drives the swing arm 622 to rotate freely on the drive shaft of the synchronous belt mechanism 603 via a one-way bearing; when cylinder 623 retracts, it drives the drive shaft of the synchronous belt mechanism 603 to rotate via the swing arm 622 and the one-way bearing, thereby driving the synchronous belt mechanism 603 to step forward and propel the paper blanks forward. Furthermore, the paper blank conveying mechanisms can be controlled to operate individually or simultaneously by controlling the cylinder 623 to operate alone or simultaneously. When changing paper blanks, simply release the thumb-type locking devices 610 and 613 and the spring plunger 614 to remove and replace the corresponding paper blank conveying mechanism and guide plate 607.

[0127] The paper blank gripping mechanism 5 is located between the paper blank storage 6 and the paper blank boxing mechanism, and is used to simultaneously grip multiple paper blanks and send them to the paper blank boxing mechanism.

[0128] like Figures 14-19 As shown, the paper blank gripping mechanism 5 includes a frame assembly 501 and a suction clamp 509. A servo motor 529 and a drive shaft 503 are mounted on the frame assembly 501 at the end away from the paper blank storage 6, and the servo motor 529 is connected to the drive shaft 503 for transmission. The output end of the servo motor 529 is connected to a reducer 504 and is fixed to one side of the upper plate of the frame assembly 501 through the reducer 504 and the fixed seat 528. The drive shaft 503 passes through the output shaft of the reducer 504 and the fixed seat 528, and its two ends are mounted on the two upper plates of the frame assembly 501 through bearings.

[0129] Two swing arm assemblies are symmetrically hinged on both sides of the frame assembly 501 near the paper blank storage 6. The swing arm assembly is formed by hinged swing arm 507 and output arm 508. The swing arm 507 is L-shaped and its lower end is hinged to the upright plate of the frame assembly 501 by a pin. The upper end of the swing arm 507 is hinged to the middle of the output arm 508. A mounting plate 525 is fixedly connected between the output arms 508 of the two swing arm assemblies by screws. The suction clamp 509 is fixed to the mounting plate 525 by two thumb-type locking devices 527.

[0130] Two crank-connecting rod assemblies are symmetrically connected at both ends of the drive shaft 503. The crank-connecting rod assembly is formed by hinged crank 505 and connecting rod 506. Crank 505 is fixedly connected to the corresponding end of the drive shaft 503, and the outer end of connecting rod 506 is respectively hinged to the middle of the corresponding swing arm 507, which is used to drive the swing arm 507 to swing back and forth.

[0131] Two control components are symmetrically hinged within the frame assembly 501. Each control component includes a small swing arm 502, a long connecting rod 510, and a short connecting rod 512. The lower end of the small swing arm 502 is hinged to the inner side of the frame assembly 501 via a hollow shaft. The upper end of the small swing arm 502 is hinged to one end of the long connecting rod 510 and the short connecting rod 512. The other end of the long connecting rod 510 is hinged to the lower end of the corresponding output arm 508. The other ends of the two short connecting rods 512 are hinged to the lower part of the two swing arms 507 via a long shaft 511. The two ends of the long shaft 511 are fixedly inserted into the two swing arms 507 and are used to control the output arm 508 to rotate back and forth as it follows the swing arm 507, thereby adjusting the angle of the suction clamp 509.

[0132] The suction clamp 509 includes a connecting plate 526, which is attached to the mounting plate 525 and fixed by the thumb-type locking device. A suction cup frame 523 is fixed on the connecting plate 526, and multiple suction cup seats 522 are evenly fixed on the suction cup frame 523 by screws. The suction cup seats 522 are rectangular frames. A baffle 521 is installed on each suction cup seat 522 by screws, and four suction cups 524 arranged in a rectangle are connected by threads. The outer ends of the suction cups 524 protrude through the through holes on the baffle 521 and are used to adsorb the paper blank material to be gripped. The suction cup frame 523 is composed of two connecting tubes and multiple connecting blocks evenly clamped on the two connecting tubes.

[0133] The frame assembly 501 includes an inner frame and an outer frame. The paper blank gripping mechanism 5 is fixed to the frame 16 via the inner frame and is located near the material outlet side of the paper blank storage 6. The servo motor 529, drive shaft 503, swing arm assembly, and control assembly are all located on the outer frame. The inner frame is formed by two symmetrically arranged L-shaped connecting seats 517 connected by two symmetrically arranged connecting shafts 518. The outer frame is formed by two upright plates 519 connected by four connecting shafts 520. The two upright plates 519 of the outer frame are respectively attached to the two sides of the inner frame and fixed to the connecting seats 517 of the inner frame by two sets of guide strips 515 and clamping plates 516 symmetrically fixed to the outside of the inner frame. The upright plates 519 are provided with strip-shaped holes corresponding to the positions of the guide strips 515. The guide strips 515 are inserted into the strip-shaped holes with clearance fit. The clamping plates 516 are connected to the guide strips 515 by screws and clamped to the outside of the strip-shaped holes.

[0134] A rotatable adjusting shaft 531 is installed on the inner frame. The two ends of the adjusting shaft 531 pass through two upright plates 519 of the outer frame and are fixed with cams 514. Square holes are provided on the two upright plates 519 corresponding to the two ends of the adjusting shaft 531, and pressure blocks 513 are fixed on the upper end of the square holes. The pressure blocks 513 press on the outer edge of the corresponding cams 514. A handwheel 530 is fixed in the middle of the adjusting shaft so that the height of the outer frame can be adjusted by rotating the adjusting shaft 531 through the cams, thereby adjusting the gripping height.

[0135] During operation, in the initial state as follows: Figure 14As shown. The servo motor 529 is started, driving the drive shaft 503 to rotate at low speed. When the drive shaft 503 rotates, it drives the two swing arm assemblies to swing back and forth via the crank-connecting rod assemblies at both ends, thereby causing the suction clamp 509 to swing back and forth. When the two swing arms 507 swing backward, the short connecting rod 512 of the two control components pushes the small swing arm 502 to swing backward, while simultaneously driving the lower end of the output arm 508 of the two swing arm assemblies to rise via the long connecting rod 510, causing the output arm 508 of the two swing arm assemblies to rotate to a horizontal state. This adjusts the angle of the suction clamp 509 as it follows the swing arm assemblies, causing the suction clamp 509 to rotate from its initial state to a horizontal state. When the suction clamp 509 is in its initial state, it grips the paper blank material in the paper blank material library 6 using the negative pressure of the suction cup 524. When the suction clamp 509 moves to a horizontal state, the paper blank material can be placed in a horizontal position, such as... Figure 6 As shown, this allows the subsequent paper blank boxing mechanism to pick up the material. By repeating this cycle, the paper blank material can be grasped and placed.

[0136] When the gripping height needs to be adjusted, loosen the screws fixing the clamp 516, rotate the adjusting shaft 531 by handwheel 530, which will drive the cam 514 to rotate, thereby adjusting the height of the outer frame and thus the gripping height. After adjustment, tighten the upper clamp 516.

[0137] like Figures 20-22 As shown, the paper blank box forming mechanism includes a paper blank gripper mechanism 4, a glue spraying mechanism 3, and a paper box forming mechanism 2, which are sequentially arranged on the frame 16 within the first structural unit.

[0138] The paper blank gripper mechanism 4 includes a two-axis linear slide 401 mounted on the frame. A mounting frame 403 is connected to the lower end of the Z-axis slide of the two-axis linear slide 401 via a quick-release assembly 402. Multiple paperboard grippers 404 are evenly distributed on the mounting frame 403. In this embodiment, four paperboard grippers are used to grip four paper blanks at the same time.

[0139] like Figures 23-24 As shown, the quick-release assembly 402 includes a connecting post 4023 and a connecting seat 4021. The connecting post 4023 is fixed to the lower end of the Z-axis slide by screws. The connecting seat 4021 is composed of a connecting base plate and two L-shaped connecting blocks symmetrically fixed to the connecting base plate by screws. The two connecting blocks form a stepped slot. The lower end of the connecting post 4023 is cubic in shape and is inserted between the two connecting blocks and connected to each other by two symmetrically arranged thumb-shaped locking devices 4025, so as to facilitate the quick disassembly and replacement of the mounting bracket 403 and the cardboard gripper 404.

[0140] The lower end of the connecting post 4023 is inserted into the stepped slot. A retaining plate 4024 is fixed at the lower end of the connecting post 4023. A pair of limiting blocks 4022 are respectively provided between the two ends of the retaining plate 4024 and the two connecting blocks of the connecting seat 4021. The pair of limiting blocks 4022 are respectively fixed on the connecting blocks and the retaining plate 4024 and are superimposed on each other, so that the lower end of the connecting post 4023 is locked in the stepped slot by the retaining plate 4024 and the two pairs of limiting blocks 4022, thereby reducing the load on the thumb-type locking device 4025.

[0141] The mounting bracket 403 is composed of an upper plate, a lower plate, and two vertical plates connected by screws between the upper and lower plates. A grooved enclosure plate 405 is fixedly fitted on the outside of the mounting bracket 403 for installing solenoid valves that control the action of each cylinder and the on / off state of the suction cup air pipe.

[0142] like Figure 25 As shown, the cardboard gripper 404 includes a support frame 4041, a push-box cylinder 4042 and suction cups 4043 symmetrically arranged on both sides of the push-box cylinder 4042 are provided in the support frame 4041, and a push-box plate 4044 is connected to the lower end of the piston rod of the push-box cylinder 4042. When the push-box plate 4044 is in the initial position, the lower end of the suction cup 4043 passes through the through hole on the push-box plate 4044.

[0143] The support frame 4041 is a rectangular box made of metal plates. The cross-sectional dimensions of the support frame 4041 match the inner cavity dimensions of the paper box to be formed. The lower part of the support frame 4041 is provided with cylinder seat plate 4046 and suction cup seat plate 4045 arranged vertically. The push-box cylinder 4042 and suction cup 4043 are respectively fixed on cylinder seat plate 4046 and suction cup seat plate 4045.

[0144] The piston rod of the pusher cylinder 4042 is connected to a pusher plate seat 4048 at its lower end. The pusher plate 4044 is fixed under the pusher plate seat 4048. Two guide components 4047 are symmetrically arranged between the pusher plate seat 4048 and the cylinder seat plate 4046. The guide sleeve of the guide component 4047 is fixed on the suction cup seat plate 4045 to realize the vertical reciprocating guidance of the pusher plate 4044.

[0145] like Figures 26-27As shown, the glue spraying mechanism 3 is mounted on the frame 16 via adjustable brackets 19 at both ends and is located in front of the paper blank gripping mechanism 5. The glue spraying mechanism 3 includes a base plate 301. Two parallel strips 304 are slidably mounted on the base plate 301 via linear slide rail assemblies 306. Multiple pairs of first glue spraying guns 307 are evenly fixed on the two strips 304 by screws. The number of pairs of first glue spraying guns 307 is equivalent to the number of paperboard grippers 404. Each pair of first glue spraying guns 307 corresponds to the inner tongues at both ends of the paper blank to be formed. Each first glue spraying gun 307 is connected to a hot melt glue device (not shown in the figure) via a glue tube and is used to spray glue onto the inner tongues 2003 at both ends of multiple paper blanks.

[0146] A lead screw and nut assembly 303 is provided between one end of each of the two strips 304 and a vertical plate 302 fixed to one end of the substrate, so as to facilitate the adjustment of the spacing of each pair of first glue spray guns 307. The lead screw of the lead screw and nut assembly 303 is rotatably mounted on the corresponding vertical plate 302, and the nut is fixed to one end of the strip 304.

[0147] A photoelectric sensor 305 is mounted on the substrate 301 between each pair of first glue guns 307 via a bracket. This sensor detects the passage of the paper blank to be formed, thereby controlling the glue spraying of the first glue gun 307. A top cover 308 is fastened between the upright plates 302 at both ends of the substrate 301. An opening is provided on the top cover 308 corresponding to the glue nozzle of each first glue gun 307 and the position of the photoelectric sensor 305.

[0148] The paper box forming mechanism 2 is mounted on the frame 16 in front of the glue spraying mechanism 3. For example... Figures 28-31 As shown, the cardboard box forming mechanism 2 includes a mounting plate 201 with multiple rectangular forming holes 2011 evenly distributed on it. A forming component is provided at each forming hole 2011, and the forming components are evenly arranged in a row, corresponding one-to-one with the number of cardboard grippers 404, for the synchronous forming of multiple packaging cardboard boxes. The forming components include guide box components and pressing box components.

[0149] The guide box assembly includes two long boxes 202 and two short boxes 203 formed by thin plates. The two long boxes 202 are fixed to the front and rear sides of each forming hole 2011 on the mounting plate 201, and the two short boxes 203 are fixed to the left and right ends of each forming hole 2011 on the mounting plate 201. The inner side plates of the long boxes 202 and the short boxes 203 are inserted into the forming holes 2011 to guide the cardboard of each packaging box when it is inserted into the forming hole 2011.

[0150] The pressing assembly includes two long-side pressing assemblies 204 and two short-side pressing assemblies 205. The two long-side pressing assemblies 204 are respectively located on the front and rear sides of each forming hole 2011 on the mounting plate 201, and the two short-side pressing assemblies 205 are respectively located on the left and right ends of each forming hole 2011 on the mounting plate 201, for pressing and forming the packaging paper box inserted into the forming hole 2011.

[0151] like Figure 31 As shown, the pressing long side assembly 204 includes a mounting block 210, which is fixed to the mounting plate 201 by a connecting plate 208 and located in the slot in the middle of the long side of each forming hole 2011. A swing seat 209 is hinged to the mounting block 210 by a pin. A pressing cylinder 207 is fixed to the mounting block 210 below the mounting plate 201 to push the swing seat 209 to swing. The middle part of the swing seat 209 is L-shaped and two rollers 212 are installed at the lower end of the swing seat 209 by a swing shaft 211 and a bearing for rolling the front and rear sides of the packaging box. A return spring 206 is provided between the upper middle part of the swing seat 209 and the mounting block 210 for automatic reset after the swing seat 209 swings.

[0152] The short-side pressing component 205 and the long-side pressing component 204 have basically the same structure and are used to roll the left and right ends of the packaging box.

[0153] During operation, when the four paper blanks are simultaneously grasped by the paper blank gripping mechanism 5 and swung to a horizontal position, the paper blanks are located directly below the four paperboard grippers 404. The controller 17 controls the Z-axis slide of the two-axis linear slide 401 to start descending, driving the four paperboard grippers 404 to descend until the suction cup 4043 contacts the corresponding upper surface of the paper blank and the paper blank is held in place by the negative pressure of the suction cup 4043.

[0154] Then, the X-axis slide of the control two-axis linear slide 401 is started, which drives the four cardboard grippers 404 to carry the adsorbed paper blanks forward in the horizontal direction until they pass the photoelectric sensor 305. The photoelectric sensor 305 detects that the paper blank has passed and sends a signal to the controller 17. The controller 17 controls the hot melt glue equipment to start, and the glue is sprayed simultaneously onto the lower surface of the inner tongue 2003 at both ends of each paper blank through the first glue spray gun 307.

[0155] Subsequently, the X-axis slide of the two-axis linear slide drives the four cardboard grippers 404 to continue moving forward until they move above the evenly distributed forming holes 2011 on the mounting plate 201. The Z-axis slide of the two-axis linear slide is then controlled to start descending, driving the cardboard grippers 404 and the paper blank to descend. The paper blank is pressed into the corresponding forming hole 2011 through the guide box assembly, and the paper blank is bent to form a paper box.

[0156] The cardboard gripper 404 drives the paper blank to continue pressing downwards between the two long-side pressing components 204 and the two short-side pressing components 205 of the box-pressing assembly. The controller 17 controls the simultaneous action of the box-pressing cylinders 207 of the long-side pressing components 204 and the short-side pressing components 205, pushing the swing seat 209 to swing. Rollers then press the four sides of the cardboard box together, achieving the bonding and forming of the cardboard box 20. Figure 32 As shown.

[0157] Finally, the Z-axis slide of the two-axis linear slide continues to move downward, pushing the paper box out of the pressing assembly and pressing it into the corresponding paper box fixing fixture on the paper box conveying mechanism 1; the controller 17 controls the suction cup 4043 to release the negative pressure, controls the pusher cylinder 4042 to start, and drives the pusher plate 4044 to push the paper box into the paper box fixing fixture. The two-axis linear slide 401 returns to the initial position along the original path to perform the next paper blank gripping.

[0158] The paper box conveying mechanism 1 includes a ring magnetic levitation conveyor line 101. One long side of the magnetic levitation conveyor line 101 is located directly below the paper box forming mechanism 2. Several trolleys are provided on the magnetic levitation conveyor line 101. Each trolley is provided with a paper box fixing clamp 102, which is used to simultaneously receive multiple paper boxes formed after the paper blank is formed and convey them forward to the next process.

[0159] like Figure 33 As shown, the cardboard box fixing clamp 102 includes a rectangular support base plate 1021. A fixing baffle 1022 is fixed on one side and one end of the support base plate 1021, and a movable baffle 1023 is hinged to the other end of the support base plate 1021. A tension spring 1024 is provided between the movable baffle 1023 and the support base plate on one side to clamp the formed cardboard box during the conveying process.

[0160] The instruction manual storage 9 has a basically the same structure as the paper blank storage 6, and is used to simultaneously place and transport multiple sets of instruction manuals. The instruction manual boxing mechanism includes an instruction manual gripping mechanism 7 and an instruction manual gripper mechanism 8. The instruction manual gripping mechanism 7 has a basically the same structure as the paper blank gripping mechanism 5, the difference being the shape of the suction cup base 522 and the baffle 521, and the number of suction cups 524. Figure 34 As shown, it is used to grab the instruction manual from the instruction manual library 9 and place it at a horizontal angle.

[0161] like Figure 35 As shown, the instruction manual gripper mechanism 8 includes a two-axis linear slide 801 mounted on the frame. A mounting frame 803 is connected to the lower end of the Z-axis slide of the two-axis linear slide 801 via a quick-release assembly 802. Multiple instruction manual grippers 804 are evenly distributed on the mounting frame 803. The number of instruction manual grippers 804 is approximately equal to the number of cardboard grippers. They are used to grip the instruction manual from the instruction manual gripping mechanism 7 and load it into the formed cardboard box located on the cardboard box conveying mechanism 1.

[0162] The instruction manual gripper 804 includes a support arm fixed below the mounting bracket 803, a suction cup seat vertically fixed to the lower end of the support arm, and three suction cups evenly distributed on the suction cup seat for adsorbing the instruction manual.

[0163] The material conveying mechanism 10 includes two parallel conveyor belt mechanisms arranged perpendicular to the magnetic levitation conveyor line. The two conveyor belt mechanisms share a drive shaft and a driven shaft and are driven by a servo motor. Several material blocks 1001 are evenly distributed and fixed on the conveyor belt of each conveyor belt mechanism for placing and conveying the materials to be packaged into the frame.

[0164] The material gripping mechanism 14 is located above the material conveying mechanism 10 and the carton conveying mechanism 1. It includes a spider robot 141, and a suction cup gripper 142 is connected to the lower end of the spider robot's gripper to simultaneously grip a pair of materials and place them into the formed carton.

[0165] like Figure 36 As shown, the suction cup gripper 142 includes a crossbeam 1421. The middle part of the crossbeam is suspended from the lower end of the gripper of the spider robot by a column 1422. Two strip-shaped suction cups 1423 and two vacuum generators 1424 are symmetrically installed at both ends of the crossbeam 1421. The vacuum generators and strip-shaped suction cups are respectively located on the upper and lower sides of both ends of the crossbeam 1421. The strip-shaped suction cups 1423 are respectively connected to the corresponding vacuum generators 1424 for adsorbing the materials to be packaged.

[0166] The inner tongue folding mechanism 15 is mounted in the frame via a bracket and is located between the material conveying mechanism 10 and the carton conveying mechanism 1. It is used to fold the inner tongues at both ends of the packaging carton.

[0167] like Figure 37-40 As shown, the inner tongue folding mechanism 15 includes a horizontally arranged mounting base plate 1501. A sliding plate 1503 is slidably mounted on the mounting base plate 1501 via two transverse slide rail assemblies 1504. A servo motor 1508 is mounted on the bottom surface of the mounting base plate 1501 along the vertical direction via a motor frame. The output end of the upper end of the servo motor 1508 is connected to the sliding plate 1503 via a crank-slider mechanism, which is used to drive the sliding plate 1503 to intermittently reciprocate along the width direction of the mounting base plate 1501.

[0168] The crank-slider mechanism includes a circular drive disk 1511 fixedly clamped to the output end of the servo motor 1508. The drive disk 1511 passes through a through hole provided on the mounting base plate 1501 and an eccentrically arranged pin 1513 is inserted into the drive disk 1511. A linkage block 1507 is fixed to the bottom surface of the sliding plate 1503 by screws. The linkage block 1507 is provided with an elongated hole. The upper end of the pin 1513 is inserted into the elongated hole through clearance fit. When the pin 1513 rotates with the drive disk 1511, it slides back and forth in the elongated hole, thereby driving the sliding plate 1503 to slide back and forth intermittently.

[0169] Limiting plates 1502 with internal limiting grooves are fixed at both ends of the sliding plate 1503 by screws. Rubber limiting posts 1514 are fixed on the mounting base plate 1501 at the corresponding positions of the limiting plates 1502. The limiting posts 1514 are inserted into the limiting grooves to realize the sliding limit of the sliding plate 1503.

[0170] Two connecting plates 1505 are slidably mounted on the sliding plate 1503 via two longitudinal slide rail assemblies 1506. The two connecting plates 1505 are parallel to each other and staggered. Drive cylinders 1510 are fixed to the sliding plate 1503 near both ends via cylinder seat plates. One end of the piston rod of the drive cylinder 1510 is connected to the corresponding connecting plate 1505 via screws and nuts, and is used to drive the two connecting plates 1505 to slide in opposite directions.

[0171] F-shaped pushers 1509 are evenly fixed to two connecting plates 1505 with screws. One end of each F-shaped pusher 1509 extends to the same side of the two connecting plates 1505. Two adjacent F-shaped pushers 1509 are symmetrically arranged, and their other ends are fixed to the two connecting plates 1505. They are used to move adjacent F-shaped pushers 1509 towards each other under the action of the connecting plates 1505, so as to fold the inner tongues at both ends of multiple packaging boxes 20 simultaneously. Each F-shaped pusher 1509 consists of a connecting rod and a U-shaped flap fixed to one end of the connecting rod. The outer end of the U-shaped flap is folded upward to protect the inner tongues at both ends of the packaging box during folding.

[0172] A protective cover 1512 is fixed to the mounting base plate 1501 by four columns and screws. The protective cover 1512 covers the sliding plate 1503, the transverse slide rail assembly, the connecting plate 1505, the longitudinal slide rail assembly and the drive cylinder 1510. The F-type pusher 1509 extends out from the opening on one side of the protective cover 1512.

[0173] During operation, the drive cylinder 1510 is initially in the extended state. The four formed packaging boxes 20 are transported to the folding mechanism by the box fixing clamp on the magnetic levitation conveyor line and stop. The servo motor 1508 is started by the controller 17. As the pin 1513 on the drive disk 1511 rotates with the drive disk 1511, it slides back and forth in the elongated hole, which drives the sliding plate 1503 to slide to one side of the packaging box, thereby driving the F-type pusher 1509 to be inserted into both sides of each packaging box 20.

[0174] Then, control the two drive cylinders 1510 to retract simultaneously, and drive each pair of adjacent F-type pushers 1509 to move towards each other through the two connecting plates 1505, pushing the inner tongues 2001 at both ends of each packaging box 20 to fold inward to a horizontal state. After the inner tongues are folded, control the drive cylinders to extend, and drive each pair of adjacent F-type pushers 1509 to move in the opposite direction to exit the packaging box.

[0175] Finally, the servo motor 1508 is started, and the crank-slider mechanism drives the sliding plate 1503 to reset, thereby driving the F-type pusher 1509 back to its initial position to prepare for the next action. After the inner tongue is folded, the controller 17 controls the spider robot to start, driving the suction cup gripper 142 to simultaneously grab a pair of materials from the two conveyor belt mechanisms and place them into the formed cardboard box. The suction cup gripper repeats the action once, thus completing the filling of four packaging boxes.

[0176] A pair of second glue spray guns are installed on the frame 16 between the third and fourth structural units. The second glue spray guns are connected to the hot melt glue equipment (not shown in the figure) through glue tubes and are used to spray glue onto the front tongue of the formed cardboard box lid. During operation, when the packaged cardboard box after filling is transported to the second glue spray gun by the cardboard box fixing clamp on the magnetic levitation conveyor line, the photoelectric sensor near the second glue spray gun detects the packaged cardboard box and sends a signal to the controller 17. The controller 17 controls the hot melt glue equipment to start, and the second glue spray gun sprays glue at two points on the inside of the front tongue 2002 of the lid of each packaged cardboard box 20 that passes by.

[0177] like Figures 41-45 As shown, the carton sealing mechanism 13 includes a two-axis linear gantry 1301 fixed on the frame 16. The two-axis linear gantry 1301 is a two-axis electric slide with an X-axis and a Z-axis. A mounting frame 1304 is detachably connected to the lower end of the Z-axis slide of the two-axis linear gantry 1301 through a connecting assembly 1302. Multiple sealing clamps 1303 are evenly distributed on the mounting frame 1304. In this embodiment, four sealing clamps are used as an example to fold and seal the top cover of four packaging cartons at the same time.

[0178] The connecting component 1302 has the same structure as the quick-release component of the paper blank boxing mechanism, so as to facilitate quick replacement when changing different specifications.

[0179] The sealing clamp 1303 includes a base plate 1307 that is evenly suspended below the mounting frame 1304 by screws via a connecting frame 1305. Two suction cups 1311 are symmetrically installed at the front end of the base plate 1307 for connecting an external air pipe to suction the top cover of the paper box 20 by negative pressure. A folding pressure plate 1309 is hinged to the front side of the base plate 1307. Support arms 1314 are symmetrically fixed on both sides of the folding pressure plate 1309 by screws. The folding pressure plate 1309 overlaps with the hinge seats 1312 fixed at both ends of the base plate 1307 through the support arms 1314 on both sides and is hinged to the hinge seats 1312 at both ends of the base plate 1307 by pins and bearings, so that the folding pressure plate 1309 is initially in a vertical state.

[0180] A folding cylinder 1308 is provided between the substrate 1307 and the folding pressure plate 1309. The two ends of the folding cylinder 1308 are respectively hinged to the upper middle part of the substrate 1307 and the folding pressure plate 1309, and are used to drive the folding pressure plate 1309 to flip and realize the folding of the top cover of the carton. The folding pressure plate 1309 is L-shaped and two tongue-pressing cylinders 1310 are symmetrically installed on the upright plate 1306 at the front end of the bottom of the folding pressure plate 1309. When the tongue-pressing cylinder 1310 is activated, its piston rod can extend out from the through hole on the inner side of the upright plate 1306, and is used to stick the glued top cover tongue to the other side of the box body.

[0181] The upright plate 1306 and the folding pressure plate 1309 are vertically connected by screws or are an integral structure. The tongue-pressing cylinder 1310 is a bolt cylinder. A positioning plate 1313 is fixed to the front end of the base plate 1307. The suction cups 1311 are led out from the through holes on the positioning plate 1313 and are used to abut against the surface of the box body on the top cover side of the positioning cardboard box. The bottom surface of the folding pressure plate 1309 is flush with the outer end surface of the positioning plate 1313 in the initial state.

[0182] During operation, when the packaged cardboard box after filling is transported to the four sealing clamps 1303 below the cardboard box fixing clamp on the magnetic levitation conveyor line, the controller 17 controls the Z-axis slide of the two-axis linear gantry 1301 to start descending, driving the four sealing clamps 1303 to descend and attach to the outer side of the top cover of the corresponding cardboard box, and the suction cup 1311 suctions the surface of the top cover of the cardboard box through negative pressure.

[0183] Then, control the folding cylinder 1308 to start, push the folding pressure plate 1309 to flip and fold the top cover of the carton until the folding pressure plate 1309 flips to a horizontal state. At this time, the top cover of the carton covers the top of the box body and the glued top cover front tongue is pressed and folded to the other side of the box body by the upright plate at the front end of the folding pressure plate 1309.

[0184] Then, the control valve cylinder 1310 is activated to push the adhesive point of the upper cover front tongue to stick to the other side surface of the box, thus sealing the box; finally, the Z-axis slide of the two-axis linear gantry 1301 is controlled to move upward, and the sealed box is taken out by the box fixing fixture, and sent to the next process by the X-axis slide of the two-axis linear gantry 1301.

[0185] A paper box turning mechanism 18 is supported by two brackets on the frame 16 between the paper box conveying mechanism 1 and the paper box output mechanism. It is used to receive the packaging paper box conveyed by the paper box sealing mechanism 13, turn the sealed packaging paper box 90 degrees and supply it to the paper box output mechanism.

[0186] like Figures 46-49 As shown, the paper box turning mechanism 18 includes a mounting plate frame 1801, which includes an upper plate and a lower plate, with the upper plate being longer than the lower plate. Vertical plates are symmetrically connected to the upper plate at both ends of the lower plate by screws, and two pairs of uprights are symmetrically connected in the middle between the upper plate and the lower plate.

[0187] A linear slide rail assembly 1802 is fixed longitudinally on the lower plate of the mounting bracket 1801, and a sliding plate 1805 is slidably mounted on the linear slide rail assembly 1802. A drive cylinder 1809 is fixed to the bottom of the mounting bracket 1801 via two L-shaped cylinder brackets. The piston rod output end of the drive cylinder 1809 is fixed to the sliding plate 1805 via a connecting bracket 1808, used to drive the sliding plate 1805 to reciprocate. The connecting bracket 1808 is inserted into the mounting bracket 1801 through a slot in the lower plate and connected to both sides of the middle portion of the sliding plate 1805 with screws.

[0188] Multiple rotating shafts 1807 are evenly mounted on the upper plate of the mounting frame 1801 via bearing seats 1806 and bearings. This embodiment uses four rotating shafts as an example. The lower end of each rotating shaft 1807 is connected to the sliding plate 1805 via a gear and rack assembly. A suction cup seat 1811 is fixed to the upper end of each rotating shaft 1807 with screws. Three suction cups 1812 are evenly connected to the suction cup seat 1811 and a box support plate 1810 is fixed thereon. The suction cups 1812 are led out from the corresponding through holes of the box support plate 1810 and are used to adsorb the material packaging box onto the box support plate 1810. The suction cup seat 1811 has a vent hole along its longitudinal direction that communicates with the suction cup mounting hole and is sealed at both ends. The rotating shaft 1807 is a hollow shaft and a connector 1813 is inserted into the upper end of its central hole. The connector 1813 is sealed to the suction cup seat 1811 and communicates with the vent hole for connecting an external air pipe to allow air to pass through the suction cup.

[0189] The gear and rack assembly consists of a gear 1803 fixed to the lower end of the rotating shaft 1807 and a small rack 1804 fixed to the sliding plate 1805. The small rack 1804 is L-shaped. The box tray 1810 has symmetrical retaining edges at both ends for holding the conveyed material packaging boxes.

[0190] During operation, the four sealed packaging boxes are placed onto the box tray 1810 by the four sealing clamps 1303 of the box sealing mechanism 13. Then, the pressure cylinder and folding cylinder of the sealing clamps are controlled to retract, release the packaging boxes, and reset to prepare for sealing the next set of boxes.

[0191] After the box tray 1810 receives the material packaging box, it is picked up and fixed by the suction cup 1812. The drive cylinder 1809 is activated, and the action of the drive cylinder 1809 pushes the sliding plate 1805 to slide on the linear slide rail assembly 1802 through the connecting frame. When sliding, the gear and rack assembly drives multiple rotating shafts 1807 to rotate synchronously, which can drive the suction cup seat 1811 and the box tray 1810 at the upper end of each rotating shaft 1807 to rotate synchronously, thereby rotating the sealed packaging box 90 degrees and supplying it to the box output mechanism.

[0192] like Figures 1-6 As shown, the carton output mechanism includes a conveyor belt conveying mechanism 11 and a carton gripper mechanism 12. The carton gripper mechanism 12 is located on the frame above the conveyor belt conveying mechanism 11 and has the same structure as the instruction manual gripper mechanism 8. It is used to grip the packaged carton after sealing and turning onto the conveyor belt conveying mechanism 11. The conveyor belt conveying mechanism 11 is arranged longitudinally along the frame and extends from one end of the frame. It is used to output the packaged carton.

[0193] During operation, the carton turning mechanism 18 turns and sends a signal to the controller 17, which then controls the two-axis linear slide of the carton gripper mechanism 12 to start. The suction cup then grabs the sealed and turned packaging carton onto the conveyor belt conveyor mechanism 11 for output.

[0194] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
