Description

Technical Field

[0001] This invention relates to the field of cardboard box packaging machinery technology, specifically a box-collecting and packaging machine device for cardboard box processing. Background Technology

[0002] Carton collection and packaging is a crucial final step in the processing of cartons and boxes. It refers to the automated or semi-automated process of sorting, stacking, wrapping, and bundling processed cartons and boxes to form neat finished packages. It is widely used in food packaging, e-commerce express delivery, and daily necessities production. Its core objectives are to improve packaging efficiency, ensure the integrity of cartons during transportation, and reduce labor costs.

[0003] In the cardboard box receiving and packing stage, aligning multiple stacked cardboard boxes is inconvenient due to their large size and weight, resulting in poor neatness. Furthermore, for premium cardboard boxes, protective cardboard must be wrapped around both sides before packing, and then secured with cable ties; otherwise, the box surface will be damaged during transportation and transshipment. However, when multiple boxes are stacked together, their overall weight makes it difficult to smoothly wrap the bottom with protective cardboard, hindering operation. Therefore, we propose a cardboard box receiving and packing machine to address these shortcomings. Summary of the Invention

A telescopic plate is telescopically installed on one side of the slider. A swing arm is installed at one end of the telescopic plate relative to the slider. The swing arm is hinged to the packaging machine platform. A lower horizontal plate is hinged to the top of the swing arm. The lower horizontal plate is slidably connected to the bottom of the outer package release box, and a top head is fixedly connected to its top. Return springs are symmetrically sleeved on both sides of the outer package release box. The return springs abut against one side of the lower horizontal plate.

[0007] A slide is fixedly connected to the lower front side of the outer packaging release box. The slide is inclined and has several guide wheels rotatably mounted on its surface. A support is provided at the bottom of the slide.

[0008] A bent rod is fixedly connected to the surface of the slider, and a plate is fixedly connected to the end of the bent rod away from the slider.

[0009] A stop bar is fixedly connected to the top of the telescopic plate. The side of the stop bar abuts against a curved frame that is fixedly connected to the slide. One side of the curved frame is curved, while the rest is straight.

[0010] The two sides of the panel are hinged with corner pieces, and torsion springs are provided on both sides of the connection between the corner pieces and the panel. The torsion springs are used to keep the two corner pieces open. A pry bar is hinged to the panel, and one side of the pry bar abuts against the outer surface of the corner piece. The panel is located between two slides.

[0011] Preferably, an installation frame is provided between the outer packaging release boxes and fixedly connected to the packaging machine. An extrusion drive component is provided in the middle of the installation frame. Curved plates are symmetrically arranged on the installation frame. A sliding groove is opened through the middle of the curved plate. A pressure roller is slidably arranged in the sliding groove. A control ring is connected to the top of the pressure roller. The control ring is movably arranged in the locking block in the extrusion drive component.

[0012] Preferably, the mounting bracket has push plates slidably connected to both sides, and a transmission rod is provided on the side of the push plate. The transmission rod is hinged to the mounting bracket. A guide groove is provided at the bottom of the transmission rod, and a protrusion is provided in the guide groove and slidably connected thereto. The protrusion is fixedly connected to the push plate. A trigger bar is fixedly connected to the top of the transmission rod, and the trigger bar movably abuts against the control ring.

[0013] Preferably, the feeding mechanism includes a first mounting plate disposed opposite to the packaging machine platform, a feeding drive component is disposed on the side of the first mounting plate, and the feeding drive component is drivenly connected to several conveyor belts.

[0014] Preferably, a baffle and a height limit plate are fixedly connected to the inner surface of the first mounting plate, and a pressure belt is rotatably mounted on the other side of the first mounting plate, with the pressure belt located above the conveyor belt.

[0015] Preferably, the steering mechanism includes a base frame fixedly installed at the bottom of the packaging machine platform, a steering drive component is provided on the base frame, the output shaft of the steering drive component is connected to a turntable, and an alignment drive component is provided on the side of the turntable.

[0017] Preferably, the adjustment mechanism includes a second mounting plate arranged opposite to each other, and an adjustment drive is provided on the second mounting plate. The adjustment drive is driven by two symmetrical side plates, which are located above the turntable.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] In this invention, after the carton has undergone multi-sided alignment, it is pushed onto the padding strip. At this time, the alignment drive is activated, causing the slider transmission swing arm to swing. The top head pushes out the bottommost protective cardboard and slides down the slide. After this stage is completed, the top head and the curved frame cause the swing arm to automatically disengage and return to its position. Then, as the slider continues to move, it pushes the protective cardboard to fit against the side of the carton stack, aligning and wrapping it, thus completing the discharge and feeding operation of the protective cardboard.

[0020] In this invention, the pressure roller is driven by the extrusion drive to extrude the cardboard boxes, eliminating excess gaps and reducing the volume of the boxes after packaging. It also limits the movement between the boxes. After the pressure roller has finished extruding, the drive rod swings and the drive push plate moves, causing the corner pieces to flip relative to each other, bending the protective cardboard and re-attaching it to the top and bottom of the box. This makes it easy to directly bind the boxes with cable ties. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1 to 7 The present invention provides a technical solution: including a baling machine platform 1, on which a feeding mechanism 2, a turning mechanism 3, an electric cylinder 4, an adjusting mechanism 5 and a settling mechanism 6 are respectively provided, and pads 7 are symmetrically arranged on the front side of the baling machine platform 1;

[0038] The packing mechanism 6 includes an outer package release box 601 disposed on both sides of the pad strip 7. An outlet 602 is provided through the bottom of the front side of the outer package release box 601, and a bottom opening 603 is provided through the bottom of the outer package release box 601.

[0039] Below the outer package release box 601, a settling drive 604 is provided. The settling drive 604 is screwed to a slider 605, and the slider 605 is slidably connected to it. A telescopic plate 606 is telescopically provided on one side of the slider 605. A swing arm 607 is provided at one end of the telescopic plate 606 relative to the slider 605. The swing arm 607 is hinged to the packaging machine platform 1. A lower horizontal plate 608 is hinged to the top of the swing arm 607. The lower horizontal plate 608 is slidably connected to the bottom of the outer package release box 601, and a top head 609 is fixedly connected to its top. Return springs 610 are symmetrically sleeved on both sides of the outer package release box 601. The return springs 610 abut against one side of the lower horizontal plate 608.

[0040] A slide 611 is fixedly connected to the lower front side of the outer package release box 601. The slide 611 is inclined and several guide wheels 612 are rotatably mounted on its surface. A support member 613 is provided at the bottom of the slide 611.

[0041] A bent rod 614 is fixedly connected to the surface of the slider 605, and a plate 617 is fixedly connected to the end of the bent rod 614 away from the slider 605.

[0042] A stop bar 615 is fixedly connected to the top of the telescopic plate 606. The side of the stop bar 615 abuts against a curved frame 616 fixedly connected to the slide rail 611. One side of the curved frame 616 is curved, and the rest is straight.

[0043] The two sides of the mounting plate 617 are hinged with corner pieces 618. Torsion springs 619 are provided on both sides of the connection between the corner pieces 618 and the mounting plate 617. The torsion springs 619 are used to keep the two corner pieces 618 in an open state. A pry bar 620 is hinged on the mounting plate 617. One side of the pry bar 620 abuts against the outer surface of the corner plate. The mounting plate 617 is located between two slides 611.

[0044] In this embodiment, the screw drives the slider 605 to move, and the slider 605 drives the telescopic plate 606 to move synchronously. The stop bar 615 at the top of the telescopic plate 606 slides along the curved frame 616. The telescopic plate 606 abuts against the swing arm 607, causing the swing arm 607 to swing around the hinge point at the bottom. The top of the swing arm 607 pushes the lower horizontal plate 608 to slide towards the cardboard box. The top head 609 of the lower horizontal plate 608 passes through the bottom opening 603 of the outer packaging release box 601, pushing the bottommost piece of the outer packaging out of the box from the outlet 602. The outer packaging slides down along the inclined slide 611. The guide wheel 612 on the surface of the slide 611 reduces friction, ensuring that the outer packaging falls smoothly and initially wraps the cardboard box. During the gradual movement, the telescopic plate 606 is retracted into the slider 605 by the stop bar 615 and the curved frame 616, and the contact with the swing arm 607 is broken. The lower horizontal plate 608 returns to the initial position under the action of the return spring 610, completing the release of the swing arm 607. The slider 605 continues to move forward. At this time, the outer package slides onto the slide rail 611. The slider 605 drives the sticking plate 617 to move closer to the carton through the curved bar 614. The sticking plate 617 appears between the slide rails 611, causing the folded corner pieces 618 on both sides to contact the outer package and lift the outer package to make it stand upright. Then, the sticking plate 617 holds the outer package in place, so that it is attached to the side of the carton stack.

[0045] An installation frame 621 is provided between the outer package release boxes 601 and is fixedly connected to the packaging machine 1. An extrusion drive 622 is provided in the middle of the installation frame 621. Curved plates 623 are symmetrically arranged on the installation frame 621. A sliding groove 624 is provided through the middle of the curved plate 623. A pressure roller 625 is slidably arranged in the sliding groove 624. A control ring 626 is connected to the top of the pressure roller 625. The control ring 626 is movably arranged in the locking block in the extrusion drive 622.

[0046] The mounting bracket 621 has a push plate 627 slidably connected to both sides. The push plate 627 has a transmission rod 628 on its side. The transmission rod 628 is hinged to the mounting bracket 621. The bottom of the transmission rod 628 has a guide groove 629. The guide groove 629 has a protrusion 630 slidably connected to it. The protrusion 630 is fixedly connected to the push plate 627. The top of the transmission rod 628 has a trigger bar 631 fixedly connected to it. The trigger bar 631 is in movable contact with the control ring 626.

[0047] In this embodiment, when the adhesive plate 617 adheres to the surface of the cardboard box, the extrusion drive 622 on the mounting bracket 621 is activated, driving the control ring 626 to move, causing the pressure roller 625 to slide along the groove 624 of the curved plate 623. The height of the pressure roller 625 is reduced, rolling and compacting the cardboard box surface, squeezing out excess gaps, and ensuring tight wrapping. When the extrusion drive 622 is activated, the control ring 626 triggers the trigger bar 631 as it reaches both ends, driving the transmission rod 628 to rotate around the hinge point. The transmission rod 628 passes through the guide groove. 629 and protrusion 630 drive push plate 627 to move in the opposite direction. The tip of push plate 627 contacts the lower part of pry bar 620 and causes it to rotate on plate 617. The other end of pry bar 620 swings downward, pressing corner piece 618 downward. Corner piece 618 is squeezed by outer packaging and rotates around hinge point, flipping 90 degrees, bending outer packaging, and simultaneously wrapping the outer packaging and the top and bottom of the cardboard box stack. Adding outer packaging to the outside of the cardboard box protects its integrity and compresses excess gaps, improving the packaging effect.

[0048] The feeding mechanism 2 includes a first mounting plate 201 that is disposed opposite to the packaging machine table 1. A feeding drive 202 is provided on the side of the first mounting plate 201, and the feeding drive 202 is connected to several conveyor belts 203.

[0049] A baffle 204 and a height limit plate 206 are fixedly connected to the inner surface of the first mounting plate 201. A pressure belt 205 is rotatably mounted on the other side of the first mounting plate 201. The pressure belt 205 is located above the conveyor belt 203.

[0050] In this embodiment, the feed drive 202 drives the conveyor belt 203 to operate, and transports the processed cartons to the packaging machine 1. The cartons are in a folded state. During the conveying process, the baffle 204 on the inner side of the first mounting plate 201 restricts the left and right displacement of the cartons, the height limit plate 206 prevents the cartons from opening, and the pressure belt 205 above adheres to the surface of the cartons and cooperates with the conveyor belt 203 to ensure smooth conveying. In this way, each carton is sent to the turntable 303 of the turning mechanism 3.

[0051] The steering mechanism 3 includes a base frame 301 fixedly installed at the bottom of the packaging machine platform 1. A steering drive 302 is provided on the base frame 301. The output shaft of the steering drive 302 is connected to a turntable 303. An alignment drive 304 is provided on the side of the turntable 303.

[0052] The turntable 303 has a cavity 305 inside, a support frame 306 is fixedly installed in the middle of the cavity 305, and alignment plates 307 are slidably arranged on both sides of the cavity 305. The alignment plates 307 are driven by the alignment drive component 304.

[0053] In this embodiment, after the cardboard boxes fall onto the turntable 303, they are stacked into multiple units. The alignment drive 304 is activated, and the two alignment plates 307 in the drive cavity 305 clamp inward to complete the left and right alignment of the cardboard boxes. According to the packaging requirements, the steering drive 302 drives the turntable 303 to rotate by a preset angle to adjust the placement direction of the cardboard boxes. The adjustment drive 502 of the adjustment mechanism 5 moves, driving the side plates 503 on both sides to move, further tidying up the position of the cardboard boxes and ensuring that they are aligned with the working area of ​​the sorting mechanism 6. Then the side plates 503 open to release the cardboard boxes.

[0054] In this embodiment, the electric cylinder 4 pushes the aligned cardboard boxes toward the stacking mechanism 6, and the stacked cardboard boxes are finally pushed onto the two pads 7.

[0055] The adjustment mechanism 5 includes a second mounting plate 501 arranged opposite to each other. An adjustment drive 502 is provided on the second mounting plate 501. The adjustment drive 502 is connected to two symmetrical side plates 503, which are located above the turntable 303.

[0057] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown:

[0058] S1: The feed drive unit 202 drives the conveyor belt 203 to operate, and transports the folded carton to the packaging machine 1. The pressure belt 205 works in conjunction with the conveyor belt 203 to ensure smooth transport and send the carton to the turntable 303.

[0059] S2: After the cartons are stacked on the turntable 303, the alignment drive 304 drives the alignment plate 307 to clamp and align them. The steering drive 302 drives the turntable 303 to rotate and adjust the placement direction. After the side plate 503 of the adjustment mechanism 5 is calibrated, it opens and releases. The electric cylinder 4 pushes the cartons onto the pad 7.

[0060] S3: The retracting drive 604 drives the slider 605 to move, and pushes the lower horizontal plate 608 through the stop bar 615 and the swing arm 607. The top head 609 pushes the outer package out from the release box and slides down the slide rail 611 to initially wrap the carton. Then the slider 605 drives the sticking plate 617 to approach, and the corner piece 618 pushes the outer package up to stick to the side of the carton.

[0061] S4: The extrusion drive 622 drives the pressure roller 625 to roll and compact the outer packaging, squeezing out the gaps. At the same time, the control ring 626 triggers the transmission rod 628, the push plate 627 drives the pry bar 620 to rotate, and the downward pressing corner piece 618 flips over to wrap the top and bottom of the carton, completing the outer packaging fixation and packaging.

[0062] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
