Description

Technical Field

[0001] This invention relates to the field of automatic lid-folding equipment for packaging boxes, and more particularly to a fully automatic lid-folding and tongue-inserting machine. Background Technology

[0002] Some packaging boxes have two side lugs and a lid at each end of the seal. When folding the box, first fold the two side lugs inward, then fold the lid, and finally fold the lid flap and insert it into the packaging box. To ensure the lid does not come loose during transportation, some packaging boxes also have an additional tongue that needs to be inserted into the lid (see attached image for details). Figure 10 (As shown).

[0003] Some traditional small and medium-sized enterprises rely on manual folding of packaging boxes. The drawback of manual operation is that it is prone to fatigue and errors, resulting in low work efficiency. Some enterprises use automated equipment for box folding. For example, Chinese Patent 202511904802.X discloses a fully automatic lid and tongue insertion machine. The processing stations of this equipment are arranged in a straight line. During operation, the packaging boxes need to be sent to each processing station in sequence for processing, which results in a long footprint of the equipment. Against this background, the applicant has carried out a brand-new design and developed a fully automatic lid folding and tongue insertion machine, which realizes automatic folding of the side ears of the packaging box, automatic folding of the lid and tongue and automatic insertion of the tongue into the box, further improving work efficiency and reducing the footprint. Summary of the Invention

[0004] The purpose of this invention is to achieve automatic folding of the side ears, lid flaps, and insert flaps of the packaging box and insert them into the box, thereby further improving work efficiency and reducing the floor space required.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A fully automatic lid-folding and tongue-inserting machine includes a box compartment, a material handling mechanism, a box-standing mechanism for standing the box upright, two sets of ear-folding mechanisms for folding the side ears of the box, a lid-pressing mechanism for pressing the box lid downwards, a lid-inserting mechanism for folding the lid flap on the lid and inserting it into the box, and a tongue-inserting mechanism for folding the inner tongue on the tongue and inserting it into the box. The two sets of ear-folding mechanisms, lid-pressing mechanisms, and lid-inserting mechanisms are all located on the side of the box-standing mechanism, and the tongue-inserting mechanism is located below the box-standing mechanism. The material handling mechanism transfers the box from the box compartment to the box-standing mechanism, and the box is operated accordingly through the box-standing mechanism, ear-folding mechanism, lid-pressing mechanism, lid-inserting mechanism, and tongue-inserting mechanism.

[0006] Furthermore, the box compartment is located above the upright box mechanism, and a material dispensing port is provided at the bottom of the box compartment.

[0007] Furthermore, the material handling mechanism includes a first driving mechanism and a suction cup, wherein the first driving mechanism drives the suction cup to move back and forth between the box compartment and the upright box mechanism.

[0008] Furthermore, the upright box mechanism includes a worktable, a baffle, a second drive mechanism, and a push plate. The baffle is fixedly installed on one side of the worktable, and the push plate is located on the other side of the worktable. The second drive mechanism drives the push plate to move back and forth toward the baffle.

[0009] Furthermore, the two sets of folding ear mechanisms are arranged opposite to each other. Each folding ear mechanism includes a third driving mechanism and a third push block. The third driving mechanism drives the third push block to move back and forth in the direction of the other set of folding ear mechanisms.

[0010] Furthermore, the capping mechanism includes a rotary cylinder and a capping strip, and the third push block is provided with an inclined surface. The rotary cylinder drives the capping strip to rotate, and the capping strip cooperates with the inclined surface.

[0011] Furthermore, the cap insertion mechanism includes a fourth driving mechanism, a fourth flap plate, a fifth driving mechanism, and a fifth push block. The fourth driving mechanism drives the fourth flap plate to move back and forth in the direction of the inclined plane, and the fifth driving mechanism drives the fifth push block to move back and forth in the direction of the inclined plane. The fourth flap plate and the fifth push block cooperate with each other.

[0012] Furthermore, the tongue insertion mechanism includes a sixth driving mechanism and a tongue support rod. A tongue support block is fixedly installed on the fourth folding tongue plate. The sixth driving mechanism drives the tongue support rod to move back and forth, and the tongue support block and the tongue support rod cooperate with each other.

[0013] Furthermore, the tongue mechanism also includes a seventh driving mechanism, a seventh folding tongue plate, an eighth driving mechanism, and an eighth push block. The seventh driving mechanism drives the seventh folding tongue plate to move back and forth in the direction of the upright box mechanism, and the eighth driving mechanism drives the eighth push block to move back and forth in the direction of the upright box mechanism. The seventh folding tongue plate and the eighth push block cooperate with each other.

[0014] Furthermore, it also includes a feeding mechanism, which further includes an air blowing mechanism and a feeding channel, the air blowing mechanism and the feeding channel cooperating with each other.

[0015] Beneficial effects: This invention uses a material handling mechanism to transfer boxes from the box storage to the box-standing mechanism. The box-standing mechanism stands the box upright, the folding lug mechanism folds the side lugs of the box, the pressing mechanism presses the lid down, the inserting mechanism folds the lid flap and inserts it into the box, and the inserting tongue mechanism folds the inner tongue and inserts it into the box, thus completing the automatic folding operation of the packaging box. Compared with manual operation, this invention further improves work efficiency. On the other hand, by placing two sets of folding lug mechanisms, pressing mechanism, and inserting mechanism on the side of the box-standing mechanism, and placing the inserting tongue mechanism below the box-standing mechanism, the subsequent folding operation can be completed as long as the packaging box is located at the box-standing mechanism. Compared with the prior art where the processing positions are arranged in a straight line, this invention further reduces the floor space required. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings. It should be noted that the directional terms such as front, back, left, right, up, and down mentioned in this application are all used in conjunction with the accompanying drawings. Figure 1 The orientation shown is the reference.

[0018] Please refer to the following in this application document: Figure 10 As shown, the packaging box 1 is simply referred to as the box. The packaging box 1 has two side ears 11, a lid 12, and a tongue 13. The lid 12 has a lid tongue 121 at its end, which needs to be inserted into the packaging box 1. The tongue 13 has an inner tongue 131 at its end. A slot 122 is provided at the fold line between the lid 12 and the lid tongue 121, and the inner tongue 131 needs to be inserted into the slot 122.

[0019] like Figures 1 to 10 The fully automatic lid folding and tongue inserting machine shown includes a box compartment 2, a material handling mechanism 3, a box standing mechanism 4, two sets of folding ear mechanisms for folding the side ears 11 of the box 5, a lid pressing mechanism for pressing the box lid 12 downwards 6, a lid inserting mechanism for folding the lid tongue 121 on the box lid 12 and inserting it into the box 7, a tongue inserting mechanism for folding the inner tongue 131 on the tongue inserting 13 and inserting it into the box 8, and a material feeding mechanism.

[0020] Please see Figure 1 and Figure 6 Two sets of folding ear mechanisms 5, pressing mechanism 6, and inserting mechanism 7 are all located on the side of the upright box mechanism 4. The box compartment 2 is located above the upright box mechanism 4, and the material picking mechanism 3 and the tongue insertion mechanism 8 are located below the upright box mechanism 4. The material picking mechanism 3 transfers the box from the box compartment 2 to the upright box mechanism 4. The upright box mechanism 4, folding ear mechanism 5, pressing mechanism 6, inserting mechanism 7, and tongue insertion mechanism 8 perform corresponding operations on the box, so that the packaging box 1 can complete subsequent operations at the upright box mechanism 4. Compared with the prior art where each processing position is arranged in a straight line, the present invention further reduces the floor space.

[0021] Please see Figure 2 and Figure 3 Box compartment 2 is located above box-standing mechanism 4. The packaging boxes 1 to be folded are flattened and stacked one after another in box compartment 2. A material retrieval port is provided at the bottom of box compartment 2.

[0022] Please see Figure 2 and Figure 4 The material handling mechanism 3 includes a first drive mechanism 31 and a suction cup 32. The first drive mechanism 31 drives the suction cup 32 to move back and forth between the box compartment 2 and the box-standing mechanism 4. During operation, the first drive mechanism 31 drives the suction cup 32 to enter the box compartment 2 from the material handling port at the bottom of the box compartment 2 and suck up the packaging box 1 located at the bottom. Then the first drive mechanism 31 pulls the packaging box 1 out from the material handling port at the bottom of the box compartment 2 and moves it to the worktable 41 of the box-standing mechanism 4.

[0023] Please see Figure 2 and Figure 5 The box-standing mechanism 4 includes a worktable 41, a baffle 42, a second drive mechanism 43, and a push plate 44. The baffle 42 is fixedly installed on one side of the worktable 41, and the push plate 44 is located on the other side of the worktable 41. The second drive mechanism 43 drives the push plate 44 to move back and forth in the direction of the baffle 42. After the packaging box 1 is placed on the worktable 41, the second drive mechanism 43 drives the push plate 44 to push forward, which, together with the baffle 42, makes the packaging box 1 stand up.

[0024] A fixing plate 45 is fixedly installed on the upper part of the push plate 44. The fixing plate 45 is perpendicular to the push plate 44. The function of the fixing plate 45 is to block the top of the packaging box 1, making the upright packaging box 1 more stable and facilitating subsequent folding operations.

[0025] Please see Figure 7 and Figure 8 Two sets of folding ear mechanisms 5 are arranged opposite each other. Each folding ear mechanism 5 includes a third drive mechanism 51 and a third push block 52. The third drive mechanism 51 drives the third push block 52 to move back and forth in the direction of the other set of folding ear mechanisms 5. After the packaging box 1 is placed on the workbench 41, the third drive mechanism 51 drives the third push block 52 to push out, folding the two folding ears of the packaging box 1.

[0026] The capping mechanism 6 includes a rotary cylinder 61 and a capping strip 62. The third push block 52 is provided with an inclined surface 521. The rotary cylinder 61 drives the capping strip 62 to rotate, and the capping strip 62 cooperates with the inclined surface 521. The rotary cylinder 61 drives the capping strip 62 to rotate, and the capping strip 62 presses the lid 12 of the packaging box 1 onto the inclined surface 521 of the third push block 52.

[0027] Please see Figure 7 and Figure 9The lid insertion mechanism 7 includes a fourth drive mechanism 71, a fourth flap plate 72, a fifth drive mechanism 73, and a fifth push block 74. The fourth drive mechanism 71 drives the fourth flap plate 72 to move back and forth in the direction of the inclined surface 521, and the fifth drive mechanism 73 drives the fifth push block 74 to move back and forth in the direction of the inclined surface 521. The fourth flap plate 72 and the fifth push block 74 cooperate with each other. When the lid 12 of the packaging box 1 is pressed on the inclined surface 521 of the third push block 52, the fourth drive mechanism 71 drives the fourth flap plate 72 to extend forward and bend the lid tongue 121 of the lid 12. Then the third drive mechanism 51 drives the third push block 52 to retract, and the fifth drive mechanism 73 drives the fifth push block 74 to push forward and push the lid tongue 121 into the packaging box 1 along the fourth flap plate 72.

[0028] Please see Figure 9 The tongue insertion mechanism 8 includes a sixth drive mechanism 81, a tongue support rod 82, a seventh drive mechanism 83, a seventh folding tongue plate 84, an eighth drive mechanism 85, and an eighth push block 86. A tongue support block 721 is fixedly installed on the fourth folding tongue plate 72. Specifically, the tongue support block 721 is fixedly installed at the lower end of the fourth folding tongue plate 72. The tongue support block 721 is used to push the tongue 13 downward, so that the tongue support rod 82 can be inserted from the side between the tongue 13 and the packaging box 1.

[0029] The sixth drive mechanism 81 drives the tongue support rod 82 to move back and forth, and the tongue support block 721 cooperates with the tongue support rod 82. When the fourth drive mechanism 71 drives the fourth folding tongue plate 72 to extend forward, the tongue support block 721 located at the bottom of the fourth folding tongue plate 72 pushes the tongue 13 downward. Then, the sixth drive mechanism 81 drives the tongue support rod 82 to extend into the side of the tongue 13 between the tongue 13 and the packaging box 1, so that the tongue 13 is in an outwardly open state.

[0030] The seventh drive mechanism 83 drives the seventh folding tongue plate 84 to move back and forth toward the upright box mechanism 4, and the eighth drive mechanism 85 drives the eighth push block 86 to move back and forth toward the upright box mechanism 4. The seventh folding tongue plate 84 and the eighth push block 86 cooperate with each other. When the tongue support rod 82 is supported between the tongue 13 and the packaging box 1, the tongue 13 is pushed open downward. At this time, the seventh drive mechanism 83 drives the seventh folding tongue plate 84 to extend upward, and cooperates with the tongue support rod 82 to fold the inner tongue 131 on the tongue 13. Then, the sixth drive mechanism 81 drives the tongue support rod 82 to retract, and the eighth drive mechanism 85 drives the eighth push block 86 to push upward, pushing the inner tongue 131 along the seventh folding tongue plate 84 into the slot 122 on the box cover 12.

[0031] The feeding mechanism also includes an air blowing mechanism and a feeding channel 9. The air blowing mechanism and the feeding channel 9 cooperate with each other. After folding, the third drive mechanism 51 drives the third push block 52 to retract. The packaging box 1 is blown to the feeding channel 9 by the air blowing mechanism and fed through the feeding channel 9.

[0032] Working principle: The packaging boxes 1 to be folded are flattened and stacked one after another in the box compartment 2. The first drive mechanism 31 drives the suction cup 32 to enter the box compartment 2 from the material inlet at the bottom of the box compartment 2 and suck up the packaging box 1 at the bottom. Then the first drive mechanism 31 pulls the packaging box 1 out from the material inlet at the bottom of the box compartment 2 and moves it to the worktable 41 of the box standing mechanism 4. The second drive mechanism 43 drives the push plate 44 to push forward, which, together with the baffle 42, makes the packaging box 1 stand up. The fixing plate 45 on the upper part of the push plate 44 blocks the top of the packaging box 1, making the packaging box 1 stand more stably and facilitating subsequent folding operations. After the packaging box 1 is placed on the workbench 41, the third drive mechanism 51 drives the third push block 52 to push out, folding the two flaps of the packaging box 1. The rotary cylinder 61 drives the capping strip 62 to rotate, and the capping strip 62 presses the box cover 12 of the packaging box 1 onto the inclined surface 521 of the third push block 52; When the lid 12 of the packaging box 1 is pressed onto the inclined surface 521 of the third pusher 52, the fourth drive mechanism 71 drives the fourth folding tongue plate 72 to extend forward and bend the lid tongue 121 of the lid 12. At the same time, the tongue support block 721 at the bottom of the fourth folding tongue plate 72 pushes the tongue 13 downward. Then the third drive mechanism 51 drives the third pusher 52 to retract, and the fifth drive mechanism 73 drives the fifth pusher 74 to push forward and push the lid tongue 121 into the packaging box 1 along the fourth folding tongue plate 72. Next, the sixth drive mechanism 81 drives the tongue support bar 82 to extend into the side of the tongue 13 between the tongue 13 and the packaging box 1, so that the tongue 13 is in an outwardly open state; the fourth drive mechanism 71 drives the fourth folding tongue plate 72 to retract, and the fifth drive mechanism 73 drives the fifth push block 74 to retract. The seventh drive mechanism 83 drives the seventh folding tongue plate 84 to extend upward, and together with the tongue support bar 82, folds the inner tongue 131 on the tongue 13. Then the sixth drive mechanism 81 drives the tongue support bar 82 to retract, and the eighth drive mechanism 85 drives the eighth push block 86 to push upward, pushing the inner tongue 131 along the seventh folding tongue plate 84 into the slot 122 on the box cover 12. After folding, the third drive mechanism 51 drives the third push block 52 to retract, and the packaging box 1 is blown to the unloading channel 9 by the air blowing mechanism and unloaded through the unloading channel 9.
