Description

Technical Field

[0001] This utility model relates to the field of product packaging technology, specifically to a flip-top boxing and edge-pulling mechanism for a boxing machine. Background Technology

[0002] In existing packaging processes, the process of sealing and folding packaging boxes, especially paper packaging boxes, is frequently used. At the same time, the flip-top cartoning machine has now completed the entire process of opening, filling and closing the lid.

[0003] For example, utility model CN214452026U discloses a novel packaging box flip-top fastening mechanism. The packaging box has an opening on one side with an inner cover and an outer cover opposite to the inner cover. The inner cover and the opening are connected by a first fold, and a gap is provided at the middle position of the first fold. A latch is connected to the outer edge of the outer cover by a second fold. The latch is adapted to the gap and can be inserted into the packaging box through the gap. This utility model realizes that the outer cover of the packaging box with an inner cover and an outer cover can be folded and fastened in a completely automated manner, freeing up manpower while improving the efficiency of packaging products and the hygiene and safety of product packaging.

[0004] However, in actual use cases of flip-top cartoning machines, users often fill the boxes quite full with materials to increase the utilization rate and aesthetics of the boxes. For example, products packaged in layers of cotton pads may be filled with these materials. During the lid-closing process, because the cotton pads are filled quite full and fit tightly against the top and bottom of the box, the lid often gets stuck between the cotton pads when closing the box. This results in the need for manual disassembly and repackaging, which affects the cartoning efficiency. Therefore, a flip-top cartoning edge-pulling mechanism for a cartoning machine is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a flip-top boxing and edge-pulling mechanism for a cartoning machine, which has the advantages of reducing subsequent manual rework processes and improving boxing efficiency, thus solving the problem of poor boxing accuracy affecting boxing efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a flip-top box-packing and edge-pulling mechanism for a cartoning machine, comprising a set of frames and a conveying assembly installed between the set of frames for conveying the box body, wherein a conveying plate is fixedly installed between the set of frames;

[0007] The frame is equipped with an adsorption pull piece for adsorbing and pulling the box opening open.

[0008] The adsorption and edge-pulling component includes a crossbeam fixedly connected to a set of frames, and a horizontal movement cylinder fixedly installed on the crossbeam. A guide rail is fixedly installed below the crossbeam. A limit block and a slidingly connected mounting frame are fixedly connected above the end of the guide rail away from the crossbeam, respectively. The limit block is located between the crossbeam and the mounting frame. A follower block is fixedly connected to the inner side of the mounting frame. A reset rod penetrating the follower block is fixedly connected to the output end of the horizontal movement cylinder. Lifting cylinders are fixedly installed on both the front and rear sides of the mounting frame. A stop block is fixedly connected to the output end of each lifting cylinder. A vertical plate is fixedly connected to the opposite side of the two stop blocks. A suction cylinder is fixedly connected to the opposite side of the two vertical plates. A mounting block is fixedly connected to the output end of each suction cylinder. A set of suction cups is fixedly connected to the lower surface of each mounting block.

[0009] On opposite sides of a set of the frame, there are respectively a snap-on cover for squeezing and folding the box cover, and a guide for guiding the dustproof wings of the folding box.

[0010] Furthermore, a slider is fixedly connected to the lower surface of the mounting bracket, and the slider is slidably connected to the guide rail. A through hole is provided on the follower block for the reset rod to pass through, and a countersunk pad is fixedly connected to the end of the reset rod that passes through one end of the follower block. The outer diameter of the countersunk pad is larger than the diameter of the through hole.

[0011] Furthermore, the inner wall of the mounting block is hollow, and both mounting blocks have vents fixedly connected to opposite sides.

[0012] Furthermore, the cover includes two horizontal plates symmetrically fixedly connected to opposite sides of a set of frames. Each horizontal plate is rotatably connected to two symmetrically distributed rotating shafts. A first motor is fixedly installed on the lower surface of the horizontal plate, and the output shaft of the first motor is fixed to the lower end of the right rotating shaft. A cam is fixedly connected to the upper end of each rotating shaft. A rotating plate is rotatably connected to the eccentric part of the two cams on the same side. A push plate is fixedly connected to the upper surface of the rotating plate, and the end of the push plate near the frame is tapered.

[0013] Furthermore, the cover includes a bracket fixedly connected to the horizontal plate, and a guide plate is fixedly installed at the upper end of the bracket, with the end of the guide plate near the push plate being arc-shaped.

[0014] Furthermore, the guide includes two fixed blocks that are symmetrically fixedly connected to opposite sides of a set of frames. A second motor is fixedly installed below the fixed blocks, and the output shaft of the second motor is fixedly connected to a push block located above the fixed blocks. Support rods are fixedly connected to opposite sides of the set of frames, and a stop block located above the frame is fixedly connected to the upper end of the support rod. A baffle is fixedly connected to the upper surface of the set of frames.

[0015] Furthermore, the baffle is located between the stop block and the guide plate, and the end of the baffle near the stop block is arc-shaped. The stop block is located between the baffle and the push block, and the end of the push block near the frame is L-shaped.

[0016] Furthermore, the conveying assembly includes four sets of sprockets, which are symmetrically mounted in pairs on opposite sides of a frame. A chain meshes on each pair of sprockets, and several equidistant conveying blocks are fixedly installed between each set of chains.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0018] 1. The flip-top boxing and edge-pulling mechanism of this cartoning machine, through the suction cup in the edge-pulling component and the abutment block, allows the subsequent box to be smoothly and accurately inserted during the lifting process. At the same time, while opening the box and pressing down the material, it does not come into contact with the material inside the box, thus avoiding secondary contamination of the product. This reduces the need for subsequent box rework processes, thereby improving the efficiency of product filling and boxing.

[0019] 2. The flip-top boxing and edge-pulling mechanism of this cartoning machine adopts a conventional conveying structure to transport the box body. That is, without changing the existing transmission structure, it does not affect the transmission cycle. At the same time, the newly added adsorption edge-pulling component is low in cost, providing a cost-effective solution for solving the problem of lid fastening in this type of cartoning machine, making it widely applicable.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 The flip-top boxing and edge-pulling mechanism of a cartoning machine in this embodiment includes a set of frames 1 and a conveying assembly installed between the set of frames 1 for conveying the box body. A conveying plate 5 is fixedly installed between the set of frames 1.

[0028] The frame 1 is equipped with an adsorption pull piece 6 for adsorbing and pulling the box opening to unfold;

[0029] A set of frames 1 is provided with a snap-on cover 7 for squeezing and folding the box cover and a guide 8 for guiding the dustproof wings of the folding box on opposite sides.

[0030] In this embodiment, the adsorption edge puller 6 can pull open the box opening conveyed by the conveying component, thereby facilitating the accurate pressing and flipping of the lid by the lid fastener 7 into the box opening, reducing subsequent rework processes and improving boxing efficiency.

[0031] It should be noted that the conveying assembly includes four sets of sprockets 2, and the four sets of sprockets 2 are symmetrically mounted in pairs on opposite sides of a set of frames 1. Each pair of sprockets 2 is engaged with a set of chains 3, and several equidistant conveying blocks 4 are fixedly installed between each set of chains 3. After the chains 3 are driven to rotate by the sprockets 2, the conveying blocks 4 on the chains 3 can be driven to support and convey the box between the conveying blocks 4, and convey it horizontally on the frame 1.

[0032] Both ends of a set of frames 1 are rotatably mounted with conveyor shafts, and the sprockets 2 at the beginning and end of the frame 1 are fixedly mounted on the two conveyor shafts on both sides. A conveyor motor is mounted on the front side of the front frame 1. At the same time, the output shaft of the conveyor motor drives the front end of the right conveyor shaft, so that the started conveyor motor drives the right conveyor shaft to rotate, thereby driving the sprocket 2 and chain 3 to rotate.

[0033] Please see Figure 2 and 5 In this embodiment, the adsorption edge-pulling component 6 includes a crossbeam 61 fixedly connected to a set of frames 1, and a transverse movement cylinder 63 is fixedly installed on the crossbeam 61. A guide rail 62 is fixedly installed below the crossbeam 61. A limit block 66 is fixedly connected to the upper part of the guide rail 62 away from the crossbeam 61, and a mounting frame 614 is slidably connected thereto. The limit block 66 is located between the crossbeam 61 and the mounting frame 614. A follower block 65 is fixedly connected to the inner side of the mounting frame 614. The output end of the transverse movement cylinder 63 is fixedly connected to... A reset rod 68 passes through the follower block 65. Lifting cylinders 67 are fixedly installed on both the front and rear sides of the mounting bracket 614. Each lifting cylinder 67 has a fixedly connected a stop block 612 at its output end. Each stop block 612 has a fixedly connected upright plate 69 on its opposite side. Each upright plate 69 has a fixedly connected suction cylinder 611 on its opposite side. Each suction cylinder 611 has a fixedly connected mounting block 610 at its output end. Each mounting block 610 has a fixedly connected set of suction cups 613 on its lower surface.

[0034] In this embodiment, when the slider 64 is in the initial position, the lifting cylinder 67 and the suction cylinder 611 extend simultaneously, causing the abutment block 612 to press against the middle part of the box body, and causing the suction cup 613 to adhere to the top of the box opening. Then, the suction cylinder 611 retracts, and the suction cup 613 pulls the box opening upwards a certain distance, opening the box body. At the same time, under the action of the abutment block 612, the mounting bracket 614 will be transported forward along with the box body by the conveying block 4. The cover 7 moves synchronously, pressing the flip cover into the box opening. The lifting cylinder 67 resets, pulling the abutment block 612 to separate from the box body. After the horizontal movement cylinder 63 resets, the reset rod 68 pulls the follower block 65 and the mounting bracket 614 to reset horizontally, so that the suction cup 613 and the abutment block 612 perform suction and edge pulling treatment on the next box body being transported.

[0035] It should be noted that a slider 64 is fixedly connected to the lower surface of the mounting bracket 614, and the slider 64 is slidably connected to the guide rail 62, so that the mounting bracket 614 can slide horizontally and stably on the guide rail 62 through the slider 64. At the same time, after the descending block 612 abuts and squeezes the box full of products, it can move horizontally on the conveyor plate 5 away from the crossbeam 61 along with the box.

[0036] The follower block 65 has a through hole for the reset rod 68 to pass through, and a countersunk pad is fixedly connected to one end of the reset rod 68 that passes through the follower block 65. The outer diameter of the countersunk pad is larger than the diameter of the through hole, so that the follower block 65 can slide horizontally on the reset rod 68, and can also be pulled by the reset rod 68 through the countersunk pad at its end to drive the mounting bracket 614 to reset together.

[0037] In addition, the inner wall of the mounting block 610 is hollow, and the opposite sides of the two mounting blocks 610 are fixedly connected to the air vents. The frame 1 is also equipped with an air pump that evacuates the mounting blocks 610, which is not shown in the figure. The air inlet is connected to the air vent through a key. After the air pump evacuates the mounting blocks 610, the suction cup 613 can be used to pull the box opening of the box body open.

[0038] Please see Figure 3 and 5 In this embodiment, the cover 7 includes two horizontal plates 71 that are symmetrically fixedly connected to one side of a set of frames 1. Each horizontal plate 71 is rotatably connected to two symmetrically distributed rotating shafts 73. A first motor 72 is fixedly installed on the lower surface of the horizontal plate 71, and the output shaft of the first motor 72 is fixed to the lower end of the right rotating shaft 73. A cam 74 is fixedly connected to the upper end of each rotating shaft 73. A rotating plate 75 is rotatably connected to the eccentric part of the two cams 74 on the same side. A push plate 76 is fixedly connected to the upper surface of the rotating plate 75, and the end of the push plate 76 near the frame 1 is tapered.

[0039] In this embodiment, after the first motor 72 drives the right rotating shaft 73 to rotate, the cam 74 at the upper end of the rotating shaft 73 will rotate accordingly. Then, the rotating plate 75, which is eccentrically connected to the cam 74, drives the end of the push plate 76 to rotate in an elliptical shape, so that the end of the push plate 76 can press the fold of the box cover to bend and be sent into the fold of the box cover to the box opening.

[0040] It should be noted that the dimensions of the push plate 76 near the frame 1 are smaller than those at the box opening, so that when the push plate 76 extends into the box opening, it will not obstruct or interfere with the box during the conveying process.

[0041] The cover 7 includes a bracket 77 fixedly connected to the horizontal plate 71, and a guide plate 78 is fixedly installed at the upper end of the bracket 77. The end of the guide plate 78 near the push plate 76 is arc-shaped. After the folding part of the box cover is squeezed and folded by the push plate 76 and sent into the box opening, the box body continuously conveyed by the conveying block 4 drives the box cover to be guided and squeezed by the arc-shaped end of the guide plate 78, so that the box cover can be completely and neatly inserted into the box opening.

[0042] Please see Figure 1 and 4-5. In this embodiment, the guide member 8 includes two fixed blocks 81 that are symmetrically fixedly connected to the opposite side of a set of frames 1. A second motor 82 is fixedly installed below the fixed block 81, and the output shaft of the second motor 82 is fixedly connected to a push block 83 located above the fixed block 81. A support rod 84 is fixedly connected to the opposite side of the set of frames 1, and a stop block 85 located above the frame 1 is fixedly connected to the upper end of the support rod 84. A baffle 86 is fixedly connected to the upper surface of the set of frames 1.

[0043] In this embodiment, during the process of conveying the box from left to right, the dustproof wing on the right side of the box can be blocked and folded into the box opening by the stop block 85 in advance. At the same time, the dustproof wing on the left side of the box, which continues to be conveyed, is aligned with the push block 83. The rotating push block 83 then rotates and squeezes the dustproof wing on the left side of the box into the box opening. Subsequently, after the dustproof wing on the left side separates from the push block 83 during the movement of the box, it can also be blocked by the stop block 85. As the box moves further, the flip cover of the box will be blocked and guided by the arc end of the baffle 86, causing the flip cover to bend towards the box opening. At the same time, after the flip cover is bent, it is blocked by the subsequent part of the baffle 86, which can block the dustproof wing of the box, thereby facilitating the subsequent further folding and insertion of the flip cover.

[0044] It should be noted that the baffle 86 is located between the stop block 85 and the guide plate 78, and the end of the baffle 86 near the stop block 85 is arc-shaped. The stop block 85 is located between the baffle 86 and the push block 83. The end of the push block 83 near the frame 1 is L-shaped, so that the flip cover and dustproof wings of the box can be blocked and folded into the box opening in sequence from left to right by the stop block 85, the push block 83, the baffle 86 and the guide plate 78.

[0045] The working principle of the above embodiments is as follows:

[0046] Step 1: Box Conveying

[0047] The conveyor motor starts, driving the conveyor shaft and sprocket 2 to rotate, thereby driving the two chains 3 to move in a cycle;

[0048] The conveyor blocks 4, fixedly mounted on the chain, move with the chain 3, forming a continuous conveyor line. Cardboard boxes are placed between adjacent conveyor blocks 4 and pushed by the conveyor blocks 4, moving stably horizontally forward on the conveyor plate 5.

[0049] Step Two: Flip-top unfolding and positioning, adsorption and traction of the edge pull piece 6.

[0050] When the box moves to below the suction pull piece 6:

[0051] Initial action: The output ends of the lifting cylinder 67 and the suction cylinder 611 on the mounting bracket 614, which are in the initial position, extend;

[0052] The lifting cylinder 67 pushes the stop block 612 downward, causing it to press against the middle of the box, thus stabilizing and positioning it.

[0053] The suction cylinder 611 pushes the mounting block 610 downward, so that the suction cup 613 fits tightly against the upper surface of the box body near the opening of the box.

[0054] Vacuum adsorption and opening: The air pump is started to draw a vacuum on the mounting block 610. The suction cup 613 firmly adsorbs the upper part of the box opening. Then, the suction cylinder 611 retracts and pulls the box opening upward a distance to fully open it, preparing for the subsequent lid closing action.

[0055] Follow-up conveying: Under the pressure of the block 612 and the adsorption of the suction cup 613, the entire mounting frame 614 slides on the guide rail 62 via the slider 64, moving horizontally together with the conveyed box, maintaining stable operation during the dynamic process;

[0056] Step 3: Pre-fold the dustproof wings, and guide component 8 begins operation.

[0057] During the transport of the box, the dustproof wings on both sides are handled by guide components 8;

[0058] Right dustproof wing: First, it is blocked by the fixed block 85 and passively folds inward into the box opening;

[0059] Left dustproof wing: When the box moves to the position of push block 83, the second motor 82 drives push block 83 to rotate. Its L-shaped end, like a paddle, precisely pushes the left dustproof wing into the box opening. Subsequently, the dustproof wing will also be continuously blocked by the subsequent stop block 85 to ensure that it will not pop open.

[0060] Pre-folding of the flip cover: As the unfolded flip cover continues to be conveyed, it will come into contact with the arc-shaped end of the baffle 86 and be guided to bend downwards initially towards the box opening;

[0061] Step 4: Pressing the flip cover in and fastening the cover part 7.

[0062] When the box body moves to position 7 of the cover fastener:

[0063] Pressing in: The first motor 72 drives the rotating shaft 73 and the cam 74 to rotate. The eccentric motion of the cam 74 is converted into a specific trajectory motion of the push plate 76, i.e., an elliptical motion, through the rotating plate 75. The conical end of the push plate 76 is inserted into the fold of the pre-folded flap and pressed into the box opening precisely.

[0064] Final shaping: The box body continues to be conveyed, and the flip cover that was just pressed in passes under the arc end of the guide plate 78. The guide plate 78 performs a final squeeze and guide on the flip cover to ensure that it is fully, tightly and flatly inserted into place, and the sealing is completed.

[0065] Step 5: Reset and Cycle

[0066] Adsorption and pulling edge component 6 reset: After the cover-closing action is completed, the lifting cylinder 67 rises, causing the stop block 612 and suction cup 613 to detach from the box. At the same time, the air pump stops and releases the vacuum.

[0067] The transverse cylinder 63 retracts, and the follower block 65 is pulled by the countersunk pad at the end of the reset rod 68, which drives the entire mounting bracket 614 to slide back to the initial position along the guide rail 62, ready to operate on the next box.

[0068] The sealed cardboard boxes are conveyed out by the conveyor line, and new empty boxes are put in for filling, and the cycle begins.
