[0063] Reference Figures 1 to 3 As shown, this embodiment provides a box-folding ear device for folding the ear 12 on the box body 11 of the packaging box 10. The ear 12 has at least one first crease 31 along the height direction of the box body 11, and a second crease 32 is provided between the ear 12 and the box body 11.

[0064] Specifically, the folding ear device includes a frame 100, a folding ear rod assembly 210, a first linear drive device 220, a second linear drive device 230, a rotary drive device 240, and a third linear drive device 310. The folding ear rod assembly 210, the first linear drive device 220, the second linear drive device 230, the rotary drive device 240, and the third linear drive device 310 are all mounted on the frame 100. The box-folding ear rod assembly 210 has ear grooves; a first linear drive device 220 drives the box-folding ear rod assembly 210 to reciprocate horizontally, so that the box ear 12 is placed in or detached from the ear groove; a second linear drive device 230 drives the box-folding ear rod assembly 210 to reciprocate vertically, so that the box-folding ear rod assembly 210 corresponds one-to-one with the first crease 31; a rotary drive device 240 drives the box-folding ear rod assembly 210 to rotate, so that the box ear 12 folds at the first crease 31; a third linear drive device 310 has a shaping block 320 connected to its drive end, and the third linear drive device 310 drives the shaping block 320 to move toward the packaging box 10, so that the box ear 12 folds at the second crease 32. Figure 1 In the diagram, direction 'a' is horizontal and direction 'b' is vertical.

[0065] In this embodiment, the first linear drive device 220 drives the folding ear rod assembly 210 to move horizontally toward the ear 12, so that the ear 12 is placed in the ear groove. The second linear drive device 230 drives the folding ear rod assembly 210 to move vertically from top to bottom, so that the folding ear rod assembly 210 corresponds one-to-one with the first crease 31. The rotation drive device 240 drives the folding ear rod assembly 210 to rotate, so that the ear 12 is folded at the first crease 31, thereby completing the folding of the ear 12 at all the first creases 31. After the folding of the ear 12 at all the first creases 31 is completed, the third linear drive device 310 drives the shaping block 320 to move toward the packaging box 10, so that the ear 12 is folded at the second crease 32, thereby completing the folding of the ear 12. The ear 12 has high consistency. The folding ear device automatically folds the ear 12 of the packaging box 10, replacing manual operation and realizing automated production of the folding ear 12 of the packaging box 10. This improves production efficiency, reduces the need for operators, thereby reducing the production cost of the product and enhancing its market competitiveness.

[0066] Preferably, the ear of the box 12 includes a first fold 21, a second fold 22, and a third fold 23 from the outermost to the innermost side. A first crease 31 is provided between the first fold 21 and the second fold 22, and between the second fold 22 and the third fold 23. A second crease 32 is provided between the third fold 23 and the box body 11. After folding, the ear of the box 12 forms a square shape. The ear of the box 12 and the product inside the box body 11 support each other, maintaining a relatively stable position for both the product and the ear of the box 12. In this embodiment, the folding ear device folds the first fold 21, the second fold 22, and the third fold 23 sequentially.

[0067] Preferably, the first linear drive device 220 is a linear cylinder, and the telescopic end of the first linear drive device 220 is fixedly connected to the rotary drive device 240. Of course, the first linear drive device 220 can also be an electric cylinder or other drive devices, and no further limitations are imposed here.

[0068] Preferably, the second linear drive device 230 is a linear cylinder, which is mounted on the frame 100, and its telescopic end is fixedly connected to the first linear drive device 220. Of course, the second linear drive device 230 can also be an electric cylinder or other drive device, which will not be further limited here.

[0069] Preferably, the third linear drive device 310 is a linear cylinder. Of course, the third linear drive device 310 can also be an electric cylinder or other drive device, which will not be further limited here.

[0070] Preferably, the rotary drive device 240 is a rotary cylinder, and the rotating end of the rotary cylinder is fixedly connected to the folding box lug assembly 210. Of course, the rotary drive device 240 can also be a motor or other drive device, and no further limitations are made here.

[0071] Specifically, a positioning mold 110 is provided on the frame 100. The positioning mold 110 is used to fix the packaging box 10 so that the packaging box 10 maintains a stable position relative to the frame 100, so as to realize automated box folding ear 12.

[0072] Specifically, the box body 11 is provided with two box ears 12, and the folding box ear rod assembly 210, the rotary drive device 240, the third linear drive device 310 and the shaping block 320 are each provided with two of each, and are provided one-to-one with the box ears 12. Specifically, the two box ears 12 are respectively provided on opposite sides of the box body 11.

[0073] In this embodiment, reference is made to Figure 4 As shown, the folding ear rod assembly 210 includes a support rod 211 and a folding rod 212. Both the support rod 211 and the folding rod 212 are mounted on the drive end of the rotary drive device 240. The axis of the support rod 211 coincides with the rotation axis of the rotary drive device 240, while the axis of the folding rod 212 is offset from the rotation axis of the rotary drive device 240. An ear groove is formed between the support rod 211 and the folding rod 212. In this embodiment, when the ear 12 is placed in the ear groove, the folding rod 212 is placed on the outside of the ear 12, and the support rod 211 is placed on the inside of the ear 12. The rotary drive device 240 rotates, causing the folding rod 212 to rotate around the support rod 211. The support rod 211 serves as a support for the ear 12, and the folding rod 212 causes the ear 12 to fold around the support rod 211. Furthermore, the folding rod 212 drives the first folding part 21 to rotate around the support rod 211, so that the first folding part 21 rotates around the second folding part 22, with a rotation angle of 80° to 90°. Furthermore, the folding rod 212 drives the second folding part 22 to rotate around the support rod 211, so that the second folding part 22 rotates around the third folding part 23, with a rotation angle of 80° to 90°.

[0074] It is worth mentioning that the second linear drive device 230 can be adjusted in position on the frame 100 in the vertical direction, so that the folding ear device can be used for the automatic folding of the ear 12 of various sizes of packaging boxes 10 with the same ear 12 but different product height and box body 11 height.

[0075] In this embodiment, reference is made to Figures 5 to 6As shown, the folding box ear device also includes a mounting platform 410, a first shaping module 420, and a fifth linear drive device 430. Specifically, a third linear drive device 310 is fixedly connected to the mounting platform 410; the first shaping module 420 includes a first shaping block 421 fixed to the mounting platform 410, a fourth linear drive device 422, and a second shaping block 423 corresponding to the first shaping block 421. A shaping groove is formed between the first shaping block 421 and the second shaping block 423. The fourth linear drive device 422 is used to drive the second shaping block 423 to move toward the first shaping block 421; the fifth linear drive device 430 is fixed to the frame 100 and connected to the mounting platform 410. The fifth linear drive device 430 is used to drive the mounting platform 410 to move in the vertical direction so that the folded ear 12 at the first crease 31 is placed in the shaping groove or removed from the shaping groove, and the third linear drive device 310 is adapted to drive the shaping block 320 to fold the ear 12 at the second crease 32. In this embodiment, taking the ear of the box 12 including two first folds 31 as an example, after the rotary drive device 240 drives the folding ear rod assembly 210 to complete the folding of the first fold 21 relative to the second fold 22, the fifth linear drive device 430 drives the mounting platform 410 and the first shaping module 420 to move toward the packaging box 10 so that part of the first fold 21 and the second fold 22, as well as the first fold 31 between the first fold 21 and the second fold 22, are placed in the shaping groove, and the ear of the box 12 is disengaged from the ear groove. The fourth linear drive device 422 drives the second shaping block 423 to move toward the first shaping block 421 and squeeze the first fold 21 and the second fold 22. After the second shaping block 423 moves into place and is held for a certain period of time, the fourth linear drive device 422 resets, reducing the rebound of the ear of the box 12, so that the first fold 21 and the second fold 22 maintain the required folding angle. Similarly, after the rotary drive device 240 drives the folding ear rod assembly 210 to complete the folding of the second fold 22 relative to the third fold 23, the fifth linear drive device 430 drives the mounting platform 410 and the first shaping module 420 to move toward the packaging box 10 so that part of the second fold 22 and the third fold 23, as well as the first crease 31 between the second fold 22 and the third fold 23, are placed in the shaping groove, and the ear 12 is disengaged from the ear groove. The fourth linear drive device 422 drives the second shaping block 423 to move toward the first shaping block 421 and press the second fold 22 and the third fold 23. After the second shaping block 423 moves into place and is held for a certain period of time, the fourth linear drive device 422 resets, reducing the rebound of the ear 12, so that the second fold 22 and the third fold 23 maintain the required folding angle. Furthermore, after the second fold 22 and the third fold 23 are shaped by the first shaping module 420, the third linear drive device 310 drives the shaping block 320 to fold the ear 12 at the second crease 32.

[0076] Specifically, the mounting platform 410 is positioned above the folding box lug assembly 210.

[0077] Specifically, there are two first shaping modules 420, each corresponding to one of the earpieces 12.

[0078] Preferably, the fourth linear drive device 422 is a linear cylinder, and the telescopic end of the fourth linear drive device 422 is fixedly connected to the second shaping block 423. Of course, the fourth linear drive device 422 can also be a motor or other drive device, and no further limitations are made here.

[0079] Preferably, the fifth linear drive device 430 is an electric cylinder, and the telescopic end of the fifth linear drive device 430 is connected to the mounting platform 410. In this embodiment, the fifth linear drive device 430 is driven by an electric cylinder powered by a motor. During actual operation, the position of the telescopic end of the fifth linear drive device 430 can be flexibly set as needed, applicable to the automatic folding of the ear 12 of various specifications of packaging boxes 10 with the same ear 12 but different product height and box body 11 height. Of course, the fifth linear drive device 430 can also be other drive devices, which are not further limited here.

[0080] Specifically, a guide assembly 470 is provided between the frame 100 and the mounting platform 410. The guide assembly 470 is configured to guide the mounting platform 410 to move in the vertical direction, so that the mounting platform 410 is more stable and reliable relative to the frame 100 and prevents the mounting platform 410 from shaking relative to the frame 100.

[0081] Specifically, the guide assembly 470 includes a sliding seat 471 and a sliding rod 472. The sliding seat 471 is fixed on the frame 100. Multiple sliding holes are provided on the sliding seat 471. Multiple sliding rods 472 are provided and slide through the sliding holes one by one. One end of the sliding rod 472 is connected to the mounting platform 410. The structure is simple and easy to assemble.

[0082] Specifically, the mounting platform 410 is provided with an inclined plate 411, which is set at an angle to the horizontal direction. The third linear drive device 310 is fixed on the inclined plate 411 so that the third linear drive device 310 drives the shaping block 320 to move along the inclined direction of the inclined plate 411, and squeezes the box ear 12 adjacent to the second crease 32 toward the inside of the packaging box 10, so that the box ear 12 adjacent to the second crease 32 is parallel to the horizontal direction. After the shaping block 320 is held for a certain period of time, the third linear drive device 310 resets, reducing the rebound of the box ear 12. Furthermore, the mounting platform 410 is provided with two inclined plates 411, which are set one-to-one with the third linear drive device 310.

[0083] It is worth mentioning that the shaping block 320 is designed in a triangular shape. When the shaping block 320 presses the ear 12 adjacent to the second crease 32 until it is parallel to the horizontal direction, the shaping block 320 contacts the surface of the ear 12, effectively improving the flatness of the ear 12 surface and preventing wrinkles. In addition, the side of the shaping block 320 that contacts the ear 12 is rounded, so that it can slide smoothly relative to the ear 12 during the contact and pressing process, thus avoiding scratches or tears to the ear 12.

[0084] In this embodiment, reference continues to be made to... Figures 5 to 6 As shown, the folding ear device also includes a stop bar 440 fixed on the mounting platform 410. The stop bar 440 can be placed inside the packaging box 10 and abut against the ear 12 to prevent the ear 12 from flipping outward. In this embodiment, taking the ear 12 as having two first folds 31 as an example, during the process of the fourth linear drive device 422 driving the second shaping block 423 to move towards the first shaping block 421 and pressing the first fold 21 and the second fold 22, the stop bar 440 is placed inside the packaging box 10 and abuts against the first fold 21 to prevent the ear 12 from flipping outward, thereby ensuring that a portion of the first fold 21 and the second fold 22 remain in the shaping groove, so that the first shaping block 421 and the second shaping block 423 can complete the pressing of the first fold 21 and the second fold 22. Similarly, during the process of the fourth linear drive device 422 driving the second shaping block 423 to move toward the first shaping block 421 and pressing the second fold 22 and the third fold 23, the stop bar 440 is placed inside the packaging box 10 and blocks the second fold 22 to prevent the box ear 12 from flipping outward, thereby ensuring that part of the second fold 22 and the third fold 23 remain in the shaping groove, so that the first shaping block 421 and the second shaping block 423 can complete the pressing of the second fold 22 and the third fold 23.

[0085] Specifically, there are two sets of stop levers 440, and each set has multiple stop levers. The two sets of stop levers 440 are configured one-to-one with the ear 12. The two sets of stop levers 440 can prevent the two ear 12 from flipping outward.

[0086] In this embodiment, reference continues to be made to... Figures 5 to 6As shown, the folding ear device also includes a sixth linear drive device 451 fixed on the mounting platform 410. The drive end of the sixth linear drive device 451 is connected to a first connecting rod 452. The first connecting rod 452 can be placed inside the packaging box 10, and the sixth linear drive device 451 is used to drive the first connecting rod 452 to rotate so that the end of the first connecting rod 452 presses against the ear 12 placed inside the packaging box 10. In this embodiment, taking the ear 12 including two first creases 31 as an example, after the second fold 22 is folded relative to the third fold 23, the sixth linear drive device 451 drives the first connecting rod 452 to rotate. The end of the first connecting rod 452 presses against the first fold 21 and holds it for a certain period of time, further maintaining the required folding angle between the first fold 21 and the second fold 22, preventing the first fold 21 from turning outward. Similarly, after the third fold 23 is folded relative to the box 11, the sixth linear drive device 451 drives the first link 452 to rotate. The end of the first link 452 presses against the second fold 22 and holds it for a certain period of time, further maintaining the required folding angle between the second fold 22 and the third fold 23, preventing the second fold 22 from turning outward.

[0087] Preferably, the sixth linear drive device 451 is a linear cylinder. Of course, the sixth linear drive device 451 can also be a motor or other drive device, which will not be further limited here.

[0088] Specifically, the telescopic end of the sixth linear drive device 451 is rotatably connected to two second connecting rods 453, and the two second connecting rods 453 are rotatably connected to two first connecting rods 452 respectively. In this embodiment, the telescopic end of the sixth linear drive device 451 moves downward in the vertical direction, and the second connecting rods 453 drive the first connecting rods 452 to rotate around the mounting platform 410. The ends of the two first connecting rods 452 simultaneously rotate from the inside of the two sets of stop rods 440 to the outside of the two sets of stop rods 440 and act on the ear 12.

[0089] Furthermore, the sixth linear drive device 451 is provided in two sets, with two sets of corresponding first connecting rods 452 and second connecting rods 453, so that the first connecting rod 452 acts stably on both sides of the ear 12 in the horizontal direction, and prevents the ear 12 from being squeezed and tilted by the first connecting rod 452.

[0090] In this embodiment, reference continues to be made to... Figures 5 to 6As shown, the folding ear device also includes a seventh linear drive device 461 fixed on the mounting platform 410. The drive end of the seventh linear drive device 461 is connected to a third shaping block 462. The seventh linear drive device 461 is used to drive the third shaping block 462 to move vertically, so that the third shaping block 462 presses against the ear 12 adjacent to the second crease 32, and the ear 12 adjacent to the second crease 32 is arranged parallel to the horizontal direction. In this embodiment, taking the ear 12 including two first creases 31 as an example, after the third linear drive device 310 drives the shaping block 320 to complete the folding of the ear 12 at the second crease 32, that is, after the third folded part 23 is folded relative to the box body 11, the seventh linear drive device 461 drives the third shaping block 462 to move vertically, so that the third shaping block 462 presses against the third folded part 23, and the third folded part 23 is parallel to the horizontal direction.

[0091] Preferably, the seventh linear drive device 461 is a linear cylinder, and the drive end, i.e., the telescopic end, of the seventh linear drive device 461 is connected to the third shaping block 462. Of course, the seventh linear drive device 461 can also be a motor or other drive device, which will not be further limited here.

[0092] Specifically, the seventh linear drive device 461 and the third shaping block 462 are each provided in pairs and are provided in a one-to-one correspondence with the ear 12.

[0093] In this embodiment, the folding ear device further includes a controller (not shown), which controls the operation of each drive device. Preferably, the controller is a PLC controller.

[0094] For example, the folding ear method of the folding ear device in Embodiment 1 can be used, referring to Figures 7 to 9 As shown, the method for folding the box ears includes the following steps:

[0095] S100, the first linear drive device 220 drives the folding box ear rod assembly 210 to move horizontally toward the box ear 12, so that the box ear 12 is placed in the ear groove, and the folding box ear rod assembly 210 corresponds to the outermost first crease 31.

[0096] In this embodiment, the outermost first crease 31 refers to the first crease 31 furthest from the box body 11 along the height direction of the packaging box 10 when the box ear 12 of the packaging box 10 is not folded.

[0097] Specifically, the folding rod 212 of the folding ear rod assembly 210 is placed on the outside of the ear 12, and the support rod 211 is placed on the inside of the ear 12.

[0098] Furthermore, before step S100, the packaging box 10 needs to be placed in the positioning mold 110.

[0099] It is worth mentioning that before step S100, all drive devices are ensured to remain in their initial state.

[0100] It is worth mentioning that, before step S100, the number of the first crease 31 can be input into the controller to facilitate subsequent control operations.

[0101] S200, the folding ear rod assembly 210 is driven to rotate by the rotary drive device 240 so that the ear 12 is folded.

[0102] Specifically, the rotary drive device 240 drives the folding rod 212 to rotate around the support rod 211. The support rod 211 serves as a support for the ear 12, thereby causing the folding rod 212 to fold around the support rod 211. In this embodiment, taking the ear 12 as having two first folds 31 as an example, the folding rod 212 can drive the first folded part 21 or the second folded part 22 to rotate around the support rod 211.

[0103] S300, the first linear drive device 220 drives the folding ear rod assembly 210 to move horizontally away from the ear 12, so that the ear 12 is disengaged from the ear slot, and the rotation drive device 240 is reset.

[0104] S400: After the second linear drive device 230 drives the folding box ear rod assembly 210 to move downward in the vertical direction and correspond to each of the remaining first creases 31 in sequence, the first linear drive device 220 drives the folding box ear rod assembly 210 to move horizontally toward the box ear 12 so that the box ear 12 is placed in the ear groove. Steps S200 and S300 are repeated in sequence until all the first creases 31 are folded.

[0105] In this embodiment, taking the ear of the box 12 as having two first folds 31 as an example, the first fold 21 is first folded relative to the second fold 22, then the second fold 22 is folded relative to the third fold 23, and finally the third fold 23 is folded relative to the box body 11.

[0106] Specifically, the following steps are also included between step S200 and step S300:

[0107] S210, the mounting platform 410 is driven to move vertically toward the packaging box 10 by the fifth linear drive device 430, so that the box ear 12 at the fold in step S200 is placed in the shaping groove.

[0108] Furthermore, the following steps are included between step S300 and step S400:

[0109] S310. The second shaping block 423 is driven to move toward the first shaping block 421 by the fourth linear drive device 422, so that the first shaping block 421 and the second shaping block 423 press the ear 12.

[0110] In this embodiment, the process of the first shaping block 421 and the second shaping block 423 pressing the ear 12 needs to be maintained for a certain period of time so that the ear 12 at the fold in step S200 maintains the required folding angle.

[0111] It is worth mentioning that when performing step S210 after folding the first fold relative to the second fold 22, the area of ​​the ear 12 placed in the shaping groove is greater than or equal to the area of ​​the ear 12 placed in the shaping groove when performing step S210 after folding the second fold relative to the third fold 23. That is, during step S310, the first shaping block 421 and the second shaping block 423 squeeze the ear 12 so that the included angle between the first fold 21 and the second fold 22 is less than or equal to the included angle between the second fold 22 and the third fold 23.

[0112] In this embodiment, step S400 specifically includes the following steps:

[0113] After the second linear drive device 230 drives the folding box ear rod assembly 210 to move vertically downward and correspond to each of the remaining first creases 31 in sequence, the first linear drive device 220 drives the folding box ear rod assembly 210 to move horizontally toward the box ear 12 so that the box ear 12 is placed in the ear groove. Then the fourth linear drive device 422 and the fifth linear drive device 430 are reset in sequence. Then steps S200, S210, S300 and S310 are repeated in sequence until all the first creases 31 are folded.

[0114] It is worth mentioning that in step S400, the process of the folding ear rod assembly 210 moving downward in the vertical direction to the process of the folding ear rod assembly 210 moving horizontally toward the ear 12 can be in any order with the process of resetting the fourth linear drive device 422 and the fifth linear drive device 430 in sequence.

[0115] It is worth mentioning that the reset process of the rotary drive device 240 in step S300 can be performed simultaneously with step S310 to improve the production efficiency of the folding ear device.

[0116] In this embodiment, after the earpiece 12 is placed in the ear canal in step S400, the following steps are also included:

[0117] S410. The first connecting rod 452 is driven to rotate by the sixth linear drive device 451 so that the end of the first connecting rod 452 presses against the box ear 12 placed inside the packaging box 10.

[0118] Specifically, such as Figure 8 and Figure 9 As shown, step S410 is executed during or after the execution of steps S210 to S310.

[0119] In this embodiment, as Figure 8 As shown, taking the earpiece 12 including two first folds 31 as an example, during the execution of steps S210 to S310, step S410 is specifically performed as follows: During the shaping process of the first shaping block 421 and the second shaping block 423 pressing the second fold 22 and the third fold 23, the sixth linear drive device 451 drives the first connecting rod 452 to rotate so that the end of the first connecting rod 452 presses against the first fold 21 and holds it for a certain period of time. When shaping the angle between the second fold 22 and the third fold 23, the required folding angle between the first fold 21 and the second fold 22 is further maintained. Further, after step S410 is completed, the fourth linear drive device 422 is reset first, and then the sixth linear drive device 451 is reset.

[0120] In this embodiment, as Figure 9 As shown, taking the ear box 12 including two first folds 31 as an example, after the execution of steps S210 to S310, step S410 is specifically executed as follows: after the first shaping block 421 and the second shaping block 423 press the second fold 22 and the third fold 23 for a period of time, the sixth linear drive device 451 drives the first connecting rod 452 to rotate so that the end of the first connecting rod 452 presses against the first fold 21, the fourth linear drive device 422 resets, and after the process of the end of the first connecting rod 452 pressing against the first fold 21 is maintained for a certain period of time, the sixth linear drive device 451 resets again.

[0121] S500, the shaping block 320 is driven to move toward the packaging box 10 by the third linear drive device 310 so that the box ear 12 is folded at the second crease 32.

[0122] In this embodiment, after the ear 12 is folded at the second crease 32, the third fold 23 is parallel to the horizontal direction, and the ear 12 is in the shape of a square.

[0123] It is worth mentioning that after step S500, the following steps are also included:

[0124] S510. The first connecting rod 452 is driven to rotate by the sixth linear drive device 451 so that the end of the first connecting rod 452 presses against the box ear 12 placed inside the packaging box 10.

[0125] Specifically, taking the ear of the box 12, which includes two first folds 31, as an example, after the shaping block 320 presses the third fold 23 to make it parallel to the horizontal direction, the sixth linear drive device 451 drives the first connecting rod 452 to rotate so that the end of the first connecting rod 452 presses against the second fold 22 and holds it for a certain period of time. When the shaping block 320 shapes the angle between the third fold 23 and the box body 11, the first connecting rod 452 maintains the required folding angle between the second fold 22 and the third fold 23. After step S510 is completed, the sixth linear drive device 451 first resets, and then the third linear drive device 310 resets.

[0126] S520. The third shaping block 462 is driven to move vertically by the seventh linear drive device 461, so that the third shaping block 462 presses against the ear 12 adjacent to the second crease 32, and the ear 12 adjacent to the second crease 32 is arranged parallel to the horizontal direction.

[0127] Specifically, taking the ear of the box 12 including two first folds 31 as an example, the process of the third shaping block 462 pressing against the third fold 23 and setting the third fold 23 parallel to the horizontal direction is maintained for a certain period of time to shape the angle between the third fold 23 and the box body 11. After step S520 is completed, the fifth linear drive device 430 and the seventh linear drive device 461 are reset.
