Description

Technical Field

[0001] This application relates to the field of packaging box processing, and in particular to a paper box processing equipment. Background Technology

[0002] As living standards improve, some products rely on unique packaging to differentiate themselves from ordinary products.

[0049] In this application, the reference to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0050] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0051] In the embodiments of this application, "parallel" includes not only the case of absolute parallelism, but also the case of approximate parallelism as commonly understood in engineering; similarly, "perpendicular" also includes not only the case of absolute perpendicularity, but also the case of approximate perpendicularity as commonly understood in engineering. For example, if the angle between two directions is 88°-95°, the two directions can be considered perpendicular; if the angle between two directions is 0°-10°, the two directions can be considered parallel.

[0052] This application provides a paper box processing device, which will be described below with reference to the accompanying drawings.

[0053] Reference Figures 1 to 17 The paper box processing equipment 1 provided in this application embodiment includes a first feeding device 10, a conveying device 20, a gluing device 30, a second feeding device 40, a bending device 50, and a defoaming device 60. The first feeding device 10 is used to provide a first paper piece 2. The conveying device 20 is configured to convey the first paper piece 2. The gluing device 30 is configured to apply glue to the first paper piece 2. The second feeding device 40 is used to provide a second paper piece 3. The second paper piece 3 includes a first main body portion 301 and two edge portions 302, which are respectively connected to opposite ends of the first main body portion 301. In the conveying direction X of the conveying device 20, the bending device 50 is located downstream of the gluing device 30. The bending device 50 is configured to simultaneously bend the two edge portions 302 of the second paper piece 3 and assemble the bent second paper piece 3 to the first paper piece 2. In the conveying direction X, the defoaming device 60 is located downstream of the bending device 50 and is configured to defoam the first paper piece 2 and the second paper piece 3.

[0054] The conveying device 20 includes a conveying mechanism 21, which supports the first paper piece 2 and conveys the first paper piece 2 along the conveying direction X. Optionally, the conveying mechanism 21 is a conveyor belt.

[0055] The transmission device 20 also includes a transmission drive mechanism connected to the transmission mechanism 21 for driving the transmission mechanism 21 to move.

[0056] In the conveying direction X, the first feeding device 10 is located upstream of the gluing device 30 and is used to provide the first paper piece 2 to the gluing device 30.

[0057] The first feeding device 10 can receive the first paper piece 2 prepared by the front-end equipment and provide the received first paper piece 2 to the gluing device 30. The first feeding device 10 can also store multiple first paper pieces 2 and provide the stored first paper pieces 2 to the gluing device 30.

[0058] The gluing device 30 applies glue to the first paper piece 2 in methods including but not limited to dispensing and rolling.

[0059] Reference Figure 5 The glue application apparatus 30 includes a glue application component 31. The glue application component 31 is used to provide an adhesive. The adhesive can be a liquid adhesive, a solid adhesive, or other suitable adhesive. Optionally, the glue application apparatus 30 includes two glue application components 31, one of which is used to provide white glue and the other is used to provide hot melt adhesive, which helps to improve the bonding strength between the first paper piece 2 and the second paper piece 3.

[0060] The gluing device 30 also includes a gluing drive mechanism 32, which is configured to drive the gluing component 31 to move in both horizontal and vertical directions. The horizontal movement of the gluing component 31 helps to expand the gluing area and improve the connection stability between the first paper piece 2 and the second paper piece 3. The vertical movement of the gluing component 31 helps to reduce interference between the gluing component 31 and the first paper piece 2, facilitating smoother transport of the first paper piece 2.

[0061] The second feeding device 40 can receive the second paper piece 3 prepared by the front-end equipment and provide it to the bending device 50. The second feeding device 40 can also store multiple second paper pieces 3 and provide the stored second paper pieces 3 to the bending device 50.

[0062] The two edges 302 of the second paper piece 3 are arranged horizontally. The arrangement direction of the two edges 302 can be parallel to the conveying direction X or perpendicular to the conveying direction X.

[0063] The bending device 50 can bend the two edge portions 302 once, or it can bend the two edge portions 302 multiple times in sequence.

[0064] The bending device 50 simultaneously bending the two edges 302 of the second paper piece 3 means that the bending device 50 can bend the two edges 302 at the same time. Optionally, the bending device 50 can bend the two edges 302 at the same time in the same direction, or it can bend the two edges 302 at the same time in different directions, so that the second paper piece 3 forms two flanges.

[0065] The bending device 50 is located downstream of the gluing device 30 and can assemble the bent second paper piece 3 to the glued first paper piece 2 so that the second paper piece 3 is bonded to the first paper piece 2.

[0066] The defoaming device 60 defoams the first paper piece 2 and the second paper piece 3 using methods including but not limited to mechanical defoaming and physical defoaming.

[0067] The defoaming device 60 can reduce air bubbles in the colloid between the first paper piece 2 and the second paper piece 3, which helps to improve the bonding strength of the first paper piece 2 and the second paper piece 3.

[0068] The paper box processing equipment 1 provided in this application embodiment pre-bends the second paper piece 3 on both sides using a bending device 50, and then assembles the pre-bent second paper piece 3 onto the first paper piece 2 to form a paper box. This facilitates the automatic processing of paper boxes with relatively complex structures, saves manpower, and improves the production efficiency and yield of paper boxes. The bending device 50 automatically and quickly assembles the pre-bent second paper piece 3 onto the first paper piece 2. The first paper piece 2 does not require forming after pre-bending, which helps reduce production steps, improves processing efficiency, and simplifies the equipment structure.

[0069] In some embodiments, refer to Figure 4 and Figure 6 The bending device 50 includes a first module 51 and a second module 52 arranged along the conveying direction X. The first module 51 and the second module 52 are configured to bend different second paper pieces 3 respectively, and assemble the bent second paper pieces 3 into first paper pieces 2 located at different workstations.

[0070] The structures of the first module 51 and the second module 52 can be the same or different.

[0071] In some examples, a first paper piece 2 can be assembled into a second paper piece 3, and the second paper piece 3 formed by bending the first module 51 and the second paper piece 3 formed by bending the second module 52 can be assembled into different first paper pieces 2 at different workstations.

[0072] In other examples, a first paper piece 2 can be assembled into two second paper pieces 3, and the second paper pieces 3 formed by bending the first module 51 and the second paper pieces 3 formed by bending the second module 52 can be sequentially assembled into the same first paper piece 2 at different workstations.

[0073] The paper box processing equipment 1 includes two bending stations. In the conveying direction X, the first module 51 is located at the upstream bending station, and the second module 52 is located at the downstream bending station. The first module 51 and the second module 52 bend the two edges 302 of different second paper pieces 3, which helps to improve the bending efficiency of the second paper pieces 3, thereby improving the processing efficiency of the paper box.

[0074] In some embodiments, the first module 51 is configured to assemble the bent second paper piece 3 into the first region 2011 of the first paper piece 2, and the second module 52 is configured to assemble the bent second paper piece 3 into the second region 2012 of the first paper piece 2. The first region 2011 and the second region 2012 are arranged along the conveying direction X.

[0075] When the first paper piece 2 is in the upstream bending station, the first area 2011 of the first paper piece 2 is set to correspond with the first module 51; when the first paper piece 2 is in the downstream bending station, the second area 2012 of the first paper piece 2 is set to correspond with the second module 52.

[0076] The second paper piece 3 formed by bending the first module 51 and the second paper piece 3 formed by bending the second module 52 are sequentially assembled into different areas of the same first paper piece 2 at different workstations.

[0077] When two second paper pieces 3 are assembled with one first paper piece 2, the two second paper pieces 3 are bent by two modules respectively, and the two bent second paper pieces 3 are assembled step by step into different areas of the first paper piece 2, which helps to improve assembly efficiency.

[0078] In some embodiments, refer to Figures 7 to 9 The first module 51 includes a bending mechanism 53, which includes a first support plate 531, a first pressure plate 532, and a bending assembly 533. The first support plate 531 supports the second paper piece 3. The first pressure plate 532 is movably disposed on the upper side of the first support plate 531 in the vertical direction Y, so that the first main body 301 is clamped between the first pressure plate 532 and the first support plate 531. The bending assembly 533 includes two bending members 5331, which can abut against two edge portions 302 respectively. The two bending members 5331 are configured to be movably disposed in the vertical direction relative to the first support plate 531 so as to simultaneously bend the two edge portions 302 in the vertical direction Y.

[0079] In some embodiments, the bending mechanism 53 further includes a first pressure plate driving mechanism 534, which is connected to the first pressure plate 532 and is used to drive the first pressure plate 532 to move in the vertical direction Y. The first pressure plate driving mechanism 534 can be a cylinder driving mechanism, a gear driving mechanism, or other suitable driving mechanism.

[0080] By moving the first pressure plate 532 downward, the first main body 301 can be pressed tightly against the first support plate 531, reducing the risk of the second paper piece 3 shifting during bending and improving the accuracy of the bending position of the second paper piece 3.

[0081] The upward movement of the first pressure plate 532 can release the bent second paper piece 3, reduce interference, facilitate the bent second paper piece 3 to enter the next station, and also facilitate the movement of the second paper piece 3 to be bent to below the first pressure plate 532.

[0082] In some embodiments, the bending assembly 533 further includes a first bending drive mechanism 5332, which is directly or indirectly connected to the two bending members 5331 and is used to drive the two bending members 5331 to move in the vertical direction. The first bending drive mechanism 5332 can be a cylinder drive mechanism, a gear drive mechanism, or other suitable drive mechanism.

[0083] The two bent parts 5331 can be set separately or formed as one piece.

[0084] Optionally, the two bending members 5331 move synchronously in the same vertical direction to simultaneously bend the two edge portions 302 in the same direction.

[0085] Specifically, when the bending mechanism 53 is working, the first pressure plate 532 moves downward and presses against the first main body 301; the two bending members 5331 move downward and abut against the upper side of the two edge portions 302 respectively; as the two bending members 5331 continue to move downward, the two edge portions 302 are bent downward.

[0086] In some embodiments, refer to Figure 7 and Figure 8 The first module 51 includes a positioning mechanism 54, and the positioning mechanism 54 and the bending mechanism 53 are arranged horizontally. The positioning mechanism 54 includes two first positioning members 541 and two second positioning members 542. The two first positioning members 541 are spaced apart on opposite sides of the first support plate 531 along the arrangement direction of the two edges 302, and the distance between the two first positioning members 541 is adjustable along the arrangement direction of the two edges 302. The two second positioning members 542 are spaced apart along the arrangement direction of the positioning mechanism 54 and the bending mechanism 53, and the arrangement direction of the positioning mechanism 54 and the bending mechanism 53 is perpendicular to the arrangement direction of the two edges 302. Each second positioning member 542 is configured to be movable along the arrangement direction of the positioning mechanism 54 and the bending mechanism 53 to adjust the distance between the two second positioning members 542 and move the second paper piece 3 between the first support plate 531 and the first pressure plate 532.

[0087] The two first positioning members 541 are arranged in a direction parallel to the arrangement direction of the two edge portions 302. The two second positioning members 542 are arranged in a horizontal direction, and the arrangement direction of the two second positioning members 542 is perpendicular to the arrangement direction of the two edge portions 302.

[0088] Optionally, the two edge portions 302 are arranged parallel to the conveying direction X, and the two first positioning members 541 are spaced apart along the conveying direction X. The positioning mechanism 54 and the bending mechanism 53 are arranged perpendicular to the conveying direction X. The two second positioning members 542 are spaced apart along a direction perpendicular to the conveying direction X.

[0089] At least one of the two first positioning members 541 is movably disposed along the arrangement direction of the two edge portions 302 to adjust the distance between the two first positioning members 541. At least one of the two first positioning members 541 can be moved by a cylinder, a motor or other suitable drive mechanism. The two first positioning members 541 are capable of positioning the second paper piece 3 supported on the first support plate 531 in the arrangement direction of the two edge portions 302.

[0090] Optionally, one of the first positioning members 541 is fixedly disposed relative to the first support plate 531, and the other first positioning member 541 is movable along the arrangement direction of the two edge portions 302, so as to reduce the control difficulty of the positioning mechanism 54 and simplify the structure of the positioning mechanism 54.

[0091] Both second positioning members 542 are movably arranged along the arrangement direction of the positioning mechanism 54 and the bending mechanism 53. On the one hand, the distance between the two second positioning members 542 can be adjusted; on the other hand, after the second paper piece 3 is accurately positioned, the movement of the two second positioning members 542 can move the second paper piece 3 between the first support plate 531 and the first pressure plate 532, facilitating the bending of the second paper piece 3. The two second positioning members 542 can move under the drive of a cylinder, a motor, or other suitable drive mechanism. The two second positioning members 542 can position the second paper piece 3 supported on the first support plate 531 in a direction perpendicular to the arrangement direction of the two edge portions 302, and move the accurately positioned second paper piece 3 to the next work station.

[0092] The positioning mechanism 54 can accurately position the second paper piece 3 on the first support plate 531 in the horizontal direction, which helps to improve the accuracy of the bending position of the second paper piece 3 and improve the production yield of the paper box.

[0093] In some embodiments, refer to Figure 2 The edge portion 302 includes a first portion 3021 and a second portion 3022, with the first portion 3021 connecting the first body portion 301 and the second portion 3022. Two bending members 5331 are configured to move toward or away from each other along the arrangement direction of the two edge portions 302 to bend the two second portions 3022 toward each other.

[0094] In some embodiments, refer to Figure 8 and Figure 9The bending assembly 533 also includes a second bending drive mechanism 5333, which is directly or indirectly connected to the two bending members 5331 and is used to drive the two bending members 5331 to move along the arrangement direction of the two edge portions 302.

[0095] The second bending drive mechanism 5333 can be a cylinder drive mechanism, a gear drive mechanism, or other suitable drive mechanism.

[0096] After the two bending members 5331 move vertically, they abut against the two second parts 3022 respectively, realizing the first bending of the second paper piece 3. Then, the second bending drive mechanism 5333 drives the two bending members 5331 to move towards each other along the arrangement direction of the two edge portions 302, so that the two second parts 3022 bend relative to the two first parts 3021 respectively, realizing the second bending of the second paper piece 3.

[0097] After the second paper piece 3 is bent, the first main body 301 is located on the upper side of the first support plate 531, the first part 3021 is located on both sides of the first support plate 531, and the second part 3022 is located on the lower side of the first support plate 531. The first support plate 531 not only provides support but also acts as a mold, which helps guide the bending of the second paper piece 3.

[0098] In some embodiments, refer to Figure 10 The first module 51 further includes an assembly mechanism 55, which includes a second support plate 551, a second pressure plate 552, and a holding assembly 553. The second support plate 551 supports the second paper piece 3 after it has been bent by the bending mechanism 53. The second pressure plate 552 is located above the second support plate 551 and is configured to be movable relative to the second support plate 551 in the vertical direction Y, so that the first main body 301 is clamped between the second pressure plate 552 and the second support plate 551. The holding assembly 553 includes two state holding members 5531, which are configured to be movable relative to the second support plate 551 in the arrangement direction of the two edge portions 302, so as to abut against the two edge portions 302 of the second paper piece 3, or release the two edge portions 302. The second support plate 551, the second pressure plate 552, and the holding assembly 553 are configured to move synchronously in the vertical direction Y to assemble the bent second paper piece 3 into the first paper piece 2.

[0099] In some embodiments, the assembly mechanism 55 further includes a second pressure plate driving mechanism 554, which is connected to the second pressure plate 552 and is used to drive the second pressure plate 552 to move relative to the second support plate 551 in the vertical direction Y. The second pressure plate driving mechanism 554 may be a cylinder driving mechanism, a gear driving mechanism, or other suitable driving mechanism.

[0100] By moving the second pressure plate 552 downward, the first main body 301 can be pressed against the second support plate 551, reducing the risk of displacement of the second paper piece 3 during assembly and improving the assembly accuracy of the second paper piece 3 and the first paper piece 2.

[0101] The upward movement of the second pressure plate 552 can release the assembled second paper piece 3, reduce interference, and facilitate the entry of the next second paper piece 3 between the second pressure plate 552 and the second support plate 551.

[0102] In some embodiments, the retaining assembly 553 further includes a retaining drive mechanism 5532, which is directly or indirectly connected to the two state retaining members 5531 and is used to drive the two state retaining members 5531 to move relative to the second support plate 551 along the arrangement direction of the two edges 302. The retaining drive mechanism 5532 may be a cylinder drive mechanism, a gear drive mechanism, or other suitable drive mechanism.

[0103] In some embodiments, the assembly mechanism 55 further includes a support plate driving mechanism 555, which drives the second support plate 551, the second pressure plate 552 and the holding assembly 553 to move synchronously in the vertical direction Y.

[0104] Specifically, when the assembly mechanism 55 is working, the second pressure plate 552 moves downward to press the second paper piece 3 against the second support plate 551, reducing the risk of displacement of the second paper piece 3; then the two state holding members 5531 move towards each other and abut against the two edge portions 302, so that the two edge portions 302 maintain a bent shape, reducing the risk of the two edge portions 302 of the second paper piece 3 automatically opening or returning to their original state; finally, the second support plate 551, the second pressure plate 552 and the holding assembly 553 move downward synchronously. After the second paper piece 3 approaches the first paper piece 2, the two state holding members 5531 release the two edge portions 302, which is conducive to the two edge portions 302 adhering to the first paper piece 2, thereby assembling the second paper piece 3 to the first paper piece 2.

[0105] In some embodiments, the structure of the second module 52 is the same as that of the first module 51, and will not be described again here.

[0106] In some embodiments, refer to Figure 4 , Figure 11 and Figure 12The defoaming device 60 includes a first defoaming mechanism 61 and a second defoaming mechanism 62. The first defoaming mechanism 61 includes a third pressure plate 611 for supporting the first paper piece 2. The second defoaming mechanism 62 includes a fourth pressure plate 621, which is movably disposed along a first direction Z to be inserted into the internal space 30a enclosed by the first main body portion 301 and the two bent edge portions 302, wherein the first direction Z, the arrangement direction of the two edge portions 302, and the vertical direction Y are perpendicular to each other. At least one of the third pressure plate 611 and the fourth pressure plate 621 is movably disposed along the vertical direction such that the second portion 3022 and at least a portion of the first paper piece 2 are clamped between the third pressure plate 611 and the fourth pressure plate 621.

[0107] Optionally, the arrangement direction of the two edge portions 302 is parallel to the conveying direction X, and the first direction Z is perpendicular to the conveying direction X.

[0108] After the two edge portions 302 are bent, the first main body portion 301 and the two edge portions 302 can form an internal space 30a. The fourth pressure plate 621 can move along the first direction Z and can be inserted into or removed from the internal space 30a.

[0109] In some examples, only the third pressure plate 611 is configured to be movable in the vertical direction Y to lift the first paper piece 2 upward, such that the second part 3022 and at least a portion of the first paper piece 2 are clamped between the third pressure plate 611 and the fourth pressure plate 621.

[0110] In other examples, only the fourth pressure plate 621 is configured to be movable in the vertical direction Y to move the second paper piece 3 downward, such that at least a portion of the second part 3022 and the first paper piece 2 are clamped between the third pressure plate 611 and the fourth pressure plate 621.

[0111] In some other examples, both the third pressure plate 611 and the fourth pressure plate 621 can move in the vertical direction Y, which makes it convenient to choose to lift the first paper piece 2 upward and / or move the second paper piece 3 downward according to the actual situation.

[0112] In some embodiments, the first defoaming mechanism 61 further includes a first defoaming driving mechanism 612, which is directly or indirectly connected to the third pressure plate 611 and is used to drive the third pressure plate 611 to move in the vertical direction Y.

[0113] In some embodiments, the second defoaming mechanism 62 further includes a second defoaming drive mechanism 622, which is directly or indirectly connected to the fourth pressure plate 621 and is used to drive the fourth pressure plate 621 to move along the first direction Z.

[0114] In some embodiments, the second defoaming mechanism 62 further includes a third defoaming driving mechanism 623, which is directly or indirectly connected to the fourth pressure plate 621 and is used to drive the fourth pressure plate 621 to move in the vertical direction Y.

[0115] The third pressure plate 611 and the fourth pressure plate 621 can press at least a portion of the second part 3022 and the first paper piece 2 in opposite directions, compressing the adhesive between the second part 3022 and the first paper piece 2, reducing air bubbles in the adhesive, and facilitating a more secure bond between the second paper piece 3 and the first paper piece 2. The fourth pressure plate 621 only presses the second part 3022 of the second paper piece 3, which helps to reduce the impact on other parts of the second paper piece 3 and lowers the risk of damaging the overall shape of the second paper piece 3.

[0116] In some embodiments, the third pressure plate 611 includes a first plate 6111 and a second plate 6112 spaced apart along the conveying direction X, the first plate 6111 and the second plate 6112 respectively supporting different areas of the first paper piece 2 distributed along the conveying direction X. The fourth pressure plate 621 includes a third plate 6211 and a fourth plate 6212 spaced apart along the conveying direction X. The third plate 6211 is configured to be inserted into the internal space 30a of the second paper piece 3 bent by the first module 51, such that the second portion 3022 of the second paper piece 3 bent by the first module 51 and a portion of the first paper piece 2 are sandwiched between the first plate 6111 and the third plate 6211. The fourth plate 6212 is configured to be inserted into the internal space 30a of the second paper piece 3 bent by the second module 52, such that the second portion 3022 of the second paper piece 3 bent by the second module 52 and a portion of the first paper piece 2 are sandwiched between the second plate 6112 and the fourth plate 6212.

[0117] The first plate 6111 and the third plate 6211 are correspondingly arranged to press the second paper piece 3 and the first paper piece 2, which are bent by the first module 51. The second plate 6112 and the fourth plate 6212 are correspondingly arranged to press the second paper piece 3 and the first paper piece 2, which are bent by the second module 52.

[0118] Optionally, the first paper component 2 includes a second main body 201 and two protrusions 202. The two protrusions 202 protrude from the same surface of the second main body 201, and the interior of each protrusion 202 is hollow. A first plate 6111 and a second plate 6112 can be inserted into the two protrusions 202 respectively, and respectively support the areas of the second main body 201 corresponding to the two protrusions 202. Two second plates 6111 3 can be respectively assembled into the areas of the second main body 201 corresponding to the two protrusions 202.

[0119] Furthermore, the first defoaming mechanism 61 also includes a fourth defoaming drive mechanism 613, which is directly or indirectly connected to the third pressure plate 611 and is used to drive the third pressure plate 611 to move along the first direction Z, so that the first plate 6111 and the second plate 6112 can be inserted into the two protrusions 202 respectively.

[0120] In the case where a first paper piece 2 is assembled with two second paper pieces 3, the embodiments of this application configure the third pressure plate 611 and the fourth pressure plate 621 to include two plates respectively. The first paper piece 2 and the two second paper pieces 3 are squeezed simultaneously by the corresponding plates, thereby simultaneously defoaming the first paper piece 2 and the two second paper pieces 3, which is beneficial to improving the defoaming efficiency and simplifying the equipment structure.

[0121] In some embodiments, refer to Figure 14 and Figure 15 The second feeding device 40 includes a first storage mechanism 41 and a second storage mechanism 42, which are separately arranged. The first storage mechanism 41 is used to provide the second paper piece 3 to the first module 51, and the second storage mechanism 42 is used to provide the second paper piece 3 to the second module 52. At least one of the first storage mechanism 41 and the second storage mechanism 42 includes a base 431, a bottom plate 432, and at least two storage bins 433. The base 431 is used to provide bottom support. The bottom plate 432 is located on the upper side of the base 431 and is configured to be rotatable relative to the base 431 about a vertical axis. At least two storage bins 433 are located on the upper side of the bottom plate 432 and are arranged in a horizontal direction. The at least two storage bins 433 are configured to be selectively located at the feeding position as the bottom plate 432 rotates.

[0122] The structures of the first storage mechanism 41 and the second storage mechanism 42 can be the same or different.

[0123] In some examples, there may be two storage bins 433, which are set opposite to each other.

[0124] In other examples, there may be three or more storage bins 433, which are distributed around the outer periphery of the rotation axis of the base plate 432.

[0125] The first storage mechanism 41 and the second storage mechanism 42 are set up separately, which is conducive to the independent feeding of the first module 51 and the second module 52, and improves the feeding efficiency.

[0126] The rotating shaft of the base plate 432 extends vertically in the Y direction. When the base plate 432 rotates, one of the storage bins 433 can be selectively rotated to the feeding station to provide the second paper piece 3 for the bending device 50. During the feeding process, the second paper piece 3 can be added to other storage bins 433 that are not in the feeding station. After the second paper piece 3 in the storage bin 433 in the feeding station is fed, the full storage bin 433 can be switched to the feeding station by rotating the base plate 432. This can realize automatic feeding without stopping the machine, which is beneficial to improving production efficiency.

[0127] In some embodiments, refer to Figure 14 and Figure 16 The second feeding device 40 also includes a first transfer mechanism 44 and a second transfer mechanism 45. The first transfer mechanism 44 is configured to transfer the second paper piece 3 of the first storage mechanism 41 to the first module 51, and the second transfer mechanism 45 is configured to transfer the second paper piece 3 of the second storage mechanism 42 to the second module 52.

[0128] The structures of the first transfer mechanism 44 and the second transfer mechanism 45 may be the same or different.

[0129] At least one of the first transfer mechanism 44 and the second transfer mechanism 45 includes a second adsorption mechanism 461 and a transfer drive mechanism 462. The second adsorption mechanism 461 is used to adsorb or release the second paper piece 3. The transfer drive mechanism 462 is configured to drive the second adsorption mechanism 461 to move in the vertical direction Y and the horizontal direction to transfer the second paper piece 3 adsorbed by the second adsorption mechanism 461 to the bending device 50.

[0130] Optionally, the second adsorption mechanism 461 can use negative pressure to adsorb the second paper piece 3, and the second adsorption mechanism 461 includes a vacuum suction cup.

[0131] The second adsorption mechanism 461 is driven to move vertically in the Y direction by the transfer drive mechanism 462. On the one hand, this allows the second adsorption mechanism 461 to move downward to a position close to the storage bin 433 to adsorb the second paper piece 3, and also allows the second adsorption mechanism 461 to move downward to a position close to the first support plate 531 to release the second paper piece 3. On the other hand, it helps to reduce interference with other structures during the transfer of the second paper piece 3.

[0132] Optionally, the second feeding device 40 is located on one side of the bending device 50 along the first direction Z. The transfer drive mechanism 462 can drive the second adsorption mechanism 461 to move along the first direction Z to transfer the second paper piece 3 to the first support plate 531 of the bending device 50.

[0133] The first module 51 and the second module 52 are fed independently by two storage mechanisms and the second paper piece 3 is transferred independently by two transfer mechanisms, which helps to reduce mutual interference and improve assembly efficiency.

[0134] In some embodiments, refer to Figure 17 The first feeding device 10 includes a flipping mechanism 11 and a first adsorption mechanism 12. The flipping mechanism 11 is configured to be rotatable relative to the conveying device 20 about a horizontal axis, the axis of rotation of the flipping mechanism 11 being perpendicular to the conveying direction X. Optionally, the flipping mechanism 11 can be mounted on the upper side of the conveying device 20. The first adsorption mechanism 12 is located on the upper side of the conveying device 20 and is fixedly connected to the flipping mechanism 11. The first adsorption mechanism 12 is configured to adsorb the first paper piece 2 upstream of the flipping mechanism 11, flip with the flipping mechanism 11, and release the first paper piece 2 downstream of the flipping mechanism 11.

[0135] The flipping mechanism 11 can drive the first adsorption mechanism 12 to rotate synchronously, so that the first adsorption mechanism 12 is upstream or downstream of the flipping mechanism 11, thereby flipping the first paper piece 2 adsorbed by the first adsorption mechanism 12 by 180°.

[0136] Optionally, there can be two first adsorption mechanisms 12. The two first adsorption mechanisms 12 are alternately located upstream of the flipping mechanism 11 and alternately located downstream of the flipping mechanism 11 as the flipping mechanism 11 flips. Each time the flipping mechanism 11 rotates 180°, it can flip one first paper piece 2.

[0137] The first feeding device 10 can rotate the first paper piece 2 from the front-end equipment by 180°, which is conducive to assembling the second paper piece 3 in a suitable posture. This realizes the automatic adjustment of the posture of the first paper piece 2 without manual operation, which helps to improve production efficiency.

[0138] In some embodiments, the first feeding device 10 includes a flipping drive mechanism 13, which is connected to the rotation shaft of the flipping mechanism 11 and is used to drive the flipping mechanism 11 to rotate.

[0139] In some embodiments, refer to Figure 4 and Figure 17 The paper box processing equipment 1 also includes a feeding device 70, which is located downstream of the defoaming device 60 in the conveying direction X. The feeding device 70 is used to output the paper box formed by assembling the first paper piece 2 and the second paper piece 3.

[0140] Optionally, the feeding device 70 is located at the end of the conveying device 20 along the conveying direction X.

[0141] Optionally, the feeding device 70 includes a feeding channel 71 and a pusher 72. The feeding channel 71 extends perpendicular to the conveying direction X, and the pusher 72 is configured to be movably disposed along the extension direction of the feeding channel 71 to push the cardboard box on the conveying device 20 into the feeding channel 71.

[0142] Although this application has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of this application. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict.
