This further reduces the risk of misalignment between the box body and inner liner. The first and second baking devices work together, baking the adhesive-applied inner liner and the bonded box body and inner liner sequentially at different stations, resulting in a good bonding effect.

[0046] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0047] The terms "first," "second," "third," etc., used in the specification, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy. In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments.

[0048] 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.

[0049] 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. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0050] 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.

[0051] This application provides a packaging box processing device for assembling a box body 2 and an inner liner 3 to form a packaging box. The packaging box processing device of this application embodiment is described below with reference to the accompanying drawings.

[0052] Reference Figures 1 to 14 The packaging box processing equipment 1 provided in this application embodiment includes a first feeding device 10, a second feeding device 20, a first transfer device 30, a second transfer device 40, an adhesive applicator 51, a first baking device 52, a pressurizing device 53, and a second baking device 62. The first feeding device 10 is used to provide a box body 2 to the box body feeding station. The first transfer device 30 is configured to transfer the box body 2 along a first direction X, such that the box body 2 is sequentially placed in a bonding station and a pressurizing station. The second feeding device 20 is used to provide an inner liner 3. The adhesive applicator 51 is configured to apply adhesive to the inner liner 3 after passing through the adhesive applicator 51. The first baking device 52 is located on one side of the adhesive applicator 51 along a second direction Y, and is configured to bake the inner liner 3 after passing through the first baking device 52. The first direction X and the second direction Y intersect. The second transfer device 40 is configured to transfer the inner liner 3 along the second direction Y such that the inner liner 3 passes sequentially through the adhesive applicator 51 and the first baking device 52, and then attaches the baked inner liner 3 to the box body 2 at the bonding station. The pressurizing device 53 is configured to pressurize the box body 2 at the pressurizing station and the inner liner 3 attached to the box body 2. The second baking device 62 is located downstream of the pressurizing device 53 and is configured to bake the pressurized box body 2 and the inner liner 3.

[0053] The first feeding device 10 can receive the boxes 2 prepared by the upstream equipment and provide the received boxes 2 to the box feeding station. The first feeding device 10 can also store multiple boxes 2 and provide the stored boxes 2 to the box feeding station.

[0054] In some examples, the first feeding device 10 feeds the provided box 2 to the first transfer device 30. In other examples, the first transfer device 30 may also remove material from the first feeding device 10.

[0055] Optionally, refer to Figure 2 The first feeding device 10 includes a first adsorption mechanism 11, a first feeding drive mechanism 12, and a second feeding drive mechanism 13. The first adsorption mechanism 11 is used to adsorb the box 2 using negative pressure or other suitable methods. The first feeding drive mechanism 12 is connected to the first adsorption mechanism 11 and is used to drive the first adsorption mechanism 11 to move along a first direction X. The second feeding drive mechanism 13 is connected to the first adsorption mechanism 11 and is used to drive the first adsorption mechanism 11 to move along a vertical direction Z.

[0056] The first transfer device 30 is a three-station transfer device, meaning it can transfer the box 2 between three stations. Specifically, the first transfer device 30 can be selectively positioned at the box loading station, the bonding station, and the pressurizing station. When the first transfer device 30 is at the box loading station, the first loading device 10 loads the box 2 onto the first transfer device 30. The first transfer device 30 can first move the box 2 along the first direction X to the bonding station, and after the box 2 is bonded to the inner liner 3, it can then move the box 2 along the first direction X to the pressurizing station.

[0057] The second feeding device 20 can receive the inner liner 3 prepared by the front-end equipment and provide the received inner liner 3 to the second transfer device 40. The second feeding device 20 can also store multiple inner liner 3 and provide the stored inner liner 3 to the second transfer device 40.

[0058] In some examples, the second feeding device 20 feeds the liner 3 it provides to the second transfer device 40. In other examples, the second transfer device 40 may also remove material from the second feeding device 20.

[0059] The adhesive application device 51 and the first baking device 52 are arranged along the second direction Y. During the process of the second transfer device 40 transferring the inner liner 3 along the second direction Y, the inner liner 3 can pass through the adhesive application device 51 and the first baking device 52 sequentially. When the second transfer device 40 carries the inner liner 3 through the adhesive application device 51, it may continue to pass through the adhesive application device 51, or it may stop at the adhesive application device 51 for a preset time. Similarly, when the second transfer device 40 carries the inner liner 3 through the first baking device 52, it may continue to pass through the first baking device 52, or it may stop at the first baking device 52 for a preset time.

[0060] The adhesive application device 51 applies adhesive to the inner lining 3 in methods including but not limited to rolling, applying adhesive, and dotting.

[0061] The first baking device 52 bakes the inner liner 3 by methods including but not limited to blowing hot air, infrared heating, and radiant heat. In actual operation, the adhesive applied to the inner liner 3 can be adjusted to a suitable viscosity by controlling the baking time and baking temperature of the first baking device 52, so as to facilitate bonding to the box body 2.

[0062] The baking method of the second baking device 62 can be the same as or different from that of the first baking device 52. Optionally, the baking method of the second baking device 62 includes, but is not limited to, hot air blowing, infrared heating, radiant heat, etc. In actual operation, the second baking device 62 can be used to completely dry the adhesive between the box body 2 and the inner liner 3 by adjusting the baking time and temperature, so as to improve the bonding strength.

[0063] The second transfer device 40 can also move the inner liner 3 along the vertical direction Z to attach the baked inner liner 3 to the box body 2 in the bonding position. The first direction X, the second direction Y, and the vertical direction Z are all perpendicular to each other.

[0064] After the box body 2 is attached to the inner liner 3, it moves along the first direction X to the pressurizing station under the drive of the first transfer device 30. The pressurizing device 53 pressurizes the box body 2 and the inner liner 3 attached to the box body 2 at the pressurizing station. Optionally, the pressurizing device 53 can squeeze the box body 2 and the inner liner 3 along the stacking direction of the box body 2 and the inner liner 3.

[0065] If the adhesive applied to the inner liner 3 has a high moisture content and good fluidity before it is bonded to the box body 2, misalignment can easily occur after the inner liner 3 and the box body 2 are bonded, affecting the product yield.

[0066] Therefore, the packaging box processing equipment 1 provided in this application embodiment is equipped with two baking devices. The first baking device 52 is located on one side of the gluing device 51 along the second direction Y, downstream of the gluing device 51. It bakes the inner liner 3 after gluing and before it is bonded to the box body 2, reducing the moisture in the adhesive applied to the inner liner 3 and increasing its viscosity, thus improving the bonding strength between the box body 2 and the inner liner 3. The second baking device 62 is located downstream of the pressurizing device 53. After pressurization, the box body 2 and the inner liner 3 are baked again by the second baking device 62, which facilitates rapid drying of the adhesive, thereby quickly bonding the box body 2 and the inner liner 3 and further reducing the risk of misalignment between the box body 2 and the inner liner 3. The first baking device 52 and the second baking device 62 work together to bake the glued inner liner 3 and the bonded box body 2 and inner liner 3 sequentially at different stations, which helps to achieve a good bonding effect.

[0067] After the box body 2 and the inner liner 3 are bonded together, pressure is applied by the pressure device 53, which helps to reduce the risk of the inner liner 3 lifting, improves the bonding strength and stability of the box body 2 and the inner liner 3, and improves the production yield of the packaging box.

[0068] In some embodiments, refer to Figure 3 The first transfer device 30 includes at least two clamping mechanisms 31 for clamping the box body 2. The at least two clamping mechanisms 31 are distributed along a first direction X and configured to move synchronously along the first direction X.

[0069] Optionally, the clamping mechanism 31 includes two clamping members 311, which are spaced apart along a first direction X. At least one clamping member 311 is configured to be movable along the first direction X so that the distance between the two clamping members 311 is adjustable. On the one hand, this helps to stably clamp the box 2 and improve the positional accuracy of the box 2. On the other hand, the clamping mechanism 31 can also clamp boxes of different sizes, which helps to improve the versatility and adaptability of the equipment.

[0070] The clamping mechanism 31 also includes a clamping drive mechanism 312, which is connected to the clamping member 311 and is used to drive the clamping member 311 to move along the first direction X.

[0071] Optionally, the first transfer device 30 further includes a connecting plate 32 and a first transfer drive mechanism 33. The first transfer drive mechanism 33 is connected to the connecting plate 32 and is used to drive the connecting plate 32 to move along the first direction X. At least two clamping mechanisms 31 are disposed on the connecting plate 32, and when the connecting plate 32 moves along the first direction X, it drives the at least two clamping mechanisms 31 to move synchronously along the first direction X.

[0072] At least two clamping mechanisms 31 are sequentially positioned at the box loading station under the drive of the first transfer device 30. After the two clamping mechanisms 31 have finished loading, they can continue to be simultaneously positioned at the bonding station and the pressurizing station under the drive of the first transfer device 30, which is beneficial for achieving dual-station bonding and pressurization and improving production efficiency.

[0073] In some embodiments, refer to Figure 3The first transfer device 30 includes four clamping mechanisms 31, which can be sequentially positioned at the box loading station under the drive of the first transfer device 30. After the first two clamping mechanisms 31 have finished loading, they move the box 2 to the bonding station, and the subsequent clamping mechanisms 31 are then positioned at the box loading station, where the inner liner 3 can be bonded to the box 2 at the bonding station while the box 2 is being loaded. After the last two clamping mechanisms 31 have finished loading, the first transfer device 30 continues to move, and the box 2 on the last two clamping mechanisms 31 is in the bonding station, while the box 2 on the first two clamping mechanisms 31 is in the pressing station. Bonding and pressing can be performed simultaneously, which helps to further improve production efficiency.

[0074] In some embodiments, the second transfer device 40 includes two transfer units 41 arranged along the first direction X. The two transfer units 41 are configured to transfer different inner linings 3 provided by the second feeding device 20 sequentially through the gluing device 51 and the first baking device 52, and respectively bond them to the two boxes 2 at the bonding station.

[0075] The structures of the two transfer units 41 can be the same or different.

[0076] Optionally, in the second direction Y, the glue application device 51 is closer to the second feeding device 20 than the first baking device 52. When each transfer unit 41 transfers the inner liner 3 along the second direction Y, the inner liner 3 can be driven to pass through the glue application device 51 first, and then through the first baking device 52.

[0077] In this embodiment, two transfer units 41 can simultaneously apply glue and bake two inner lining parts 3, realizing dual-station glue application and baking of the inner lining parts 3. This is beneficial for cooperating with at least two clamping mechanisms 31 to achieve dual-station bonding and pressurization, thereby improving production and processing efficiency.

[0078] In this embodiment, an adhesive applicator 51 is used to apply adhesive to the inner lining 3 transferred by two transfer units 41, and a first baking device 52 is used to bake the adhesive-applied inner lining 3 transferred by the two transfer units 41. This helps to reduce the number of adhesive applicators 51 and the first baking device 52, and simplifies the structure of the packaging box processing equipment 1.

[0079] In some embodiments, refer to Figure 4 The second feeding device 20 includes a storage mechanism 21, two transfer mechanisms 22, and two positioning mechanisms 23. The storage mechanism 21 is used to store the inner liner 3. The transfer mechanism 22 is configured to transfer the inner liner 3 stored in the storage mechanism 21 to the positioning mechanism 23. The positioning mechanism 23 is configured to position the inner liner 3 in a first direction X and a second direction Y.

[0080] The storage mechanism 21 stores a certain amount of inner lining 3 in advance, which helps to improve the feeding efficiency of inner lining 3.

[0081] The positioning mechanism 23 can accurately position the inner liner 3 in the first direction X and the second direction Y, which helps to reduce the risk of misalignment between the inner liner 3 and the box body 2, improve the assembly accuracy of the inner liner 3 and the box body 2, and thus improve the production yield of the packaging box.

[0082] In some embodiments, the storage mechanism 21 includes at least two first storage bins 211 and at least two second storage bins 212. The at least two first storage bins 211 are configured to alternately occupy a first liner loading station, and the at least two second storage bins 212 are configured to alternately occupy a second liner loading station. Two positioning mechanisms 23 are arranged along a first direction X, and an adhesive applicator 51 is disposed on one side of the two positioning mechanisms 23 along a second direction Y. In the second direction Y, a first baking device 52 is disposed on the side of the adhesive applicator 51 opposite to the two positioning mechanisms 23. Two transfer mechanisms 22 are configured to transfer the liner 3 in the first storage bin 211 at the first liner loading station and the liner 3 in the second storage bin 212 at the second liner loading station to the two positioning mechanisms 23, respectively.

[0083] Two transfer units 41 are configured to sequentially transfer the inner linings 3 from the two positioning mechanisms 23 through the gluing device 51 and the first baking device 52, and respectively bond them to the two boxes 2 at the bonding station. The first storage bin 211 and the second storage bin 212 can be set separately or integrated together.

[0084] In some examples, there may be two first storage bins 211, which are arranged opposite each other and are movable along their arrangement direction to alternately occupy the first liner loading station.

[0085] In other examples, there may be three or more first storage bins 211, which are distributed along the outer periphery of a vertical axis and are rotatably arranged along the vertical axis to alternately occupy the first liner loading station.

[0086] In some examples, there may be two second storage bins 212, which are arranged opposite each other and are movable along their arrangement direction to alternately occupy the second liner loading station.

[0087] In other examples, there may be three or more second storage bins 212, which are distributed along the outer periphery of a vertical axis and are rotatably arranged along the vertical axis to alternately occupy the second liner loading station.

[0088] Optionally, the storage mechanism 21 includes a base 213 and a base plate 214. The base 213 provides bottom support. The base plate 214 is disposed on the upper side of the base 213 and configured to be movably disposed relative to the base 213 along a first direction X. At least two first storage bins 211 and at least two second storage bins 212 are disposed on the upper side of the base plate 214 and arranged along the first direction X. The at least two first storage bins 211 and at least two second storage bins 212 move synchronously with the movement of the base plate 214. The at least two first storage bins 211 alternately occupy a first liner loading position as the base plate 214 moves. The at least two second storage bins 212 alternately occupy a second liner loading position as the base plate 214 moves.

[0089] The two transfer mechanisms 22 can have the same or different structures.

[0090] The two positioning mechanisms 23 can have the same or different structures.

[0091] Optionally, the first inner liner loading station and the second inner liner loading station are arranged along the first direction X, the two transfer mechanisms 22 are arranged along the first direction X, and the two positioning mechanisms 23 are arranged along the first direction X.

[0092] In the packaging box processing equipment 1 of this application embodiment, the feeding, transfer, and positioning of the inner liner 3 are all dual-station operations, which facilitates the dual-station bonding and pressurization of the inner liner 3 and the box body 2, thereby improving production efficiency. There are at least two first storage bins 211 and two second storage bins 212, allowing one of the first storage bins 211 to be positioned at the first inner liner feeding station and one of the second storage bins 212 to be positioned at the second inner liner feeding station, thus providing the inner liner 3 normally. During the feeding process of the inner liner 3, inner liner 3 can be supplemented to other first storage bins 211 and second storage bins 212 that are not positioned at the inner liner feeding station, which facilitates automatic feeding without stopping the machine and improves production efficiency.

[0093] In some embodiments, refer to Figure 5 The positioning mechanism 23 includes a support plate 231, two first positioning members 232, and two second positioning members 233. The support plate 231 supports the inner liner 3 transferred by the transfer mechanism 22. The two first positioning members 232 are arranged along a first direction X, and the distance between the two first positioning members 232 is adjustable along the first direction X to position the inner liner 3 on the support plate 231 along the first direction X. The two second positioning members 233 are arranged along a second direction Y, and the distance between the two second positioning members 233 is adjustable along the second direction Y to position the inner liner 3 on the support plate 231 along the second direction Y.

[0094] Two first positioning members 232 are spaced apart along a first direction X. At least one of the two first positioning members 232 is movable along the first direction X to adjust the distance between the two first positioning members 232. At least one of the two first positioning members 232 can be moved by a cylinder, a motor or other suitable drive mechanism.

[0095] Optionally, one of the first positioning members 232 is fixedly disposed relative to the support plate 231, and the other first positioning member 232 is movable along the first direction X, so as to reduce the control difficulty of the positioning mechanism 23 and simplify the structure of the positioning mechanism 23.

[0106] The transfer unit 41 can move the inner liner 3 along the vertical direction Z and the second direction Y, which is beneficial to accurately fit the inner liner 3 to the preset position of the box body 2.

[0107] In some embodiments, the first baking device 52 may include a plurality of air ducts 521 arranged along a second direction Y, with the air outlets of the air ducts 521 facing upwards, and the first baking device 52 is configured to blow airflow through the air ducts 521 to the inner liner 3 passing through the first baking device 52.

[0108] The inner liner 3 has its adhesive surface facing downwards, while the air outlet of the air duct 521 faces upwards. Hot air can be blown toward the lower surface of the inner liner 3 to quickly reduce the moisture in the adhesive.

[0109] The upward-facing air outlet of the air duct 521 facilitates placing the first baking device 52 at the bottom of the entire equipment, making it less likely to interfere with the second transfer device 40 or other structures, resulting in a more rational structural layout.

[0110] In some embodiments, refer to Figure 10 The pressurizing device 53 includes two pressurizing units 531 arranged along the first direction X. The two pressurizing units 531 are configured to pressurize the two boxes 2 in the pressurizing position and the two inner linings 3 respectively attached to the two boxes 2.

[0111] By pressurizing the two boxes 2 and the two inner linings 3 in the pressurization station through the two pressurization units 531, the pressurization efficiency is improved, thereby increasing the production efficiency.

[0112] In some embodiments, the pressurizing unit 531 includes a pressure plate 534, a first pressurizing drive mechanism 532, and a second pressurizing drive mechanism 533.

[0114] In some embodiments, refer to Figure 1 The packaging box processing equipment 1 also includes a conveying device 61. The conveying device 61 is located downstream of the pressurizing station and is configured to convey the box body 2 and the inner liner 3 attached to the box body 2 along a first direction X.

Optionally, the transmission mechanism is a conveyor belt.

[0116] Optionally, the second baking device 62 includes a baking channel extending along the first direction X, which is open towards the conveying device 61. The portion of the box body 2 with the inner liner 3 attached and the inner liner 3 passing through the baking channel along the first direction X under the transmission of the conveying device 61 are beneficial to prolonging the baking time and improving the adhesion between the box body 2 and the inner liner 3.

[0117] The second baking device 62 is located on the upper side of the conveying device 61. It can bake the box body 2 and the inner liner 3 while the conveying device 61 is conveying them, which is conducive to achieving non-stop baking and improving production efficiency.

[0118] In some embodiments, refer to Figure 13 The packaging box processing equipment 1 also includes a limiting mechanism 64. The limiting mechanism 64 includes a limiting plate 641 and a support assembly 642. The support assembly 642 is fixedly connected to the limiting plate 641 and is configured to suspend the limiting plate 641 above the conveying device 61. A portion of the box body 2 and the inner liner 3 on the conveying device 61 are located between the limiting plate 641 and the conveying device 61.

[0119] The support assembly 642 can be fixedly mounted on the upper side of the transmission device 61. There can be multiple support assemblies 642, which are distributed at intervals along the first direction X, which helps to improve the support stability of the limiting plate 641.

[0120] The limiting plate 641 is suspended above the transmission device 61. A gap can be formed between the limiting plate 641 and the transmission device 61. A part of the box body 2 and the inner liner 3 can be confined in the gap between the limiting plate 641 and the transmission device 61, which is beneficial to further limit the box body 2 and the inner liner 3 to improve the baking effect.

[0121] In some embodiments, refer to Figure 11 The packaging box processing equipment 1 also includes a defoaming device 63, located downstream of the second baking device 62 along the conveying direction of the conveying device 61, and configured to defoam the box body 2 and the inner liner 3. The defoaming device 63 is located on one side of the conveying device 61 along the second direction Y. The packaging box processing equipment 1 also includes a stop plate 71 and a pushing mechanism 72. The stop plate 71 is suspended above the conveying device 61 and is configured to be movable relative to the conveying device 61 to block the box body 2 on the conveying device 61 from moving along the first direction X or to release the box body 2. The pushing mechanism 72 is configured to push the box body 2 along the second direction Y to push the box body 2 blocked by the stop plate 71 to the defoaming station or to push the box body 2 in the defoaming station back to the conveying device 61.

[0122] In some embodiments, refer to Figure 11 and Figure 12 The defoaming device 63 includes a substrate 631, a defoaming plate 632, and a defoaming drive mechanism 633. The defoaming plate 632 is disposed on the upper side of the substrate 631, and the defoaming drive mechanism 633 is connected to the defoaming plate 632 for driving the defoaming plate 632 to move in the vertical direction Z to clamp the box 2 and the inner liner 3 located between the substrate 631 and the defoaming plate 632, thereby defoaming the box 2 and the inner liner 3.

[0123] Optionally, the stop plate 71 has a vertical displacement along the Z direction. When the stop plate 71 moves downward to a preset position, it can block the box 2 on the transmission device 61 from moving along the first direction X. When the stop plate 71 returns to its original position, it can release the blocking effect on the box 2, thereby releasing the box 2. The box 2 can then move along the first direction X to the next work station under the transmission action of the transmission device 61.

[0124] Optionally, refer to Figure 14The pushing mechanism 72 includes a first pushing member 721 and a second pushing member 722, which are arranged along a second direction Y. The first pushing member 721 is configured to be movable along the second direction Y under the drive of a cylinder or other driving mechanism, and the second pushing member 722 is configured to be movable along the second direction Y under the drive of a cylinder or other driving mechanism.

[0125] By moving the first pusher 721 and the second pusher 722, the box body, which is stopped by the stop plate 71, can be confined between the first pusher 721 and the second pusher 722. Then, the first pusher 721 and the second pusher 722 move along the second direction Y toward the defoaming device 63 to move at least a portion of the box body 2 and the inner liner 3 to the defoaming station. After defoaming is completed, the first pusher 721 and the second pusher 722 move along the second direction Y away from the defoaming device 63 to push the box body 2 and the inner liner 3 attached to the box body 2 back to the conveying device 61. Thereafter, the stop plate 71 can move upward to release the box body 2.

[0126] The defoaming device 63 is located downstream of the second baking device 62 and can reduce air bubbles in the colloid between the box body 2 and the inner liner 3, which is beneficial to improving the bonding strength between the two. In this embodiment of the application, by setting the stop plate 71 and the pushing mechanism 72, defoaming can be performed on the outside of the transmission device 61 on the box body 2 and the inner liner 3, which is beneficial to improving the defoaming effect and reducing the risk of damaging the transmission device 61.
