Description

Technical Field

[0001] This utility model relates to the technical field of packaging box processing equipment, and more specifically, to a packaging box forming equipment. Background Technology

[0002] In automated packaging box production equipment, efficiently and accurately conveying unformed boxes to the forming mold is a crucial step. Currently, the common conveying method typically uses a linear conveyor structure, directly transporting the unformed boxes from the side of the mold to a predetermined position directly below the mold for further processing. However, during the forming process on the mold, folding devices (such as flip-rod folding mechanisms) are usually installed on both sides of the mold to perform the folding operation on the sides of the packaging. The folding device's swinging area is mainly concentrated in the side wings and upper space of the mold. Therefore, the movement trajectory of the main structure or components of the linear conveyor structure performing the conveying action is prone to spatial intersection or overlap with the trajectory of the folding device's moving parts. This can lead to a risk of collision between the folding device and the conveyor mechanism when the packaging box is folded, affecting production continuity and safety. Furthermore, the conveying path of the linear conveyor structure spans the width of the mold. To achieve continuous feeding, a long conveyor belt is usually required to transport the unformed boxes, thus increasing the overall size of the equipment in the width direction of the mold and occupying a large production space.

[0047] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Unless otherwise specified, the materials and equipment used in this embodiment are all commercially available.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0048] In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, "a plurality of" means two or more, unless otherwise precisely specified.

[0049] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a connection through an intermediary, or a connection within two elements or an interaction between two elements. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0050] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products, or apparatuses.

[0051] It should be noted that, as Figure 17 As shown, the packaging box 200 involved in this utility model is a rectangular box shape, specifically a wine box, used to form the outer packaging of wine bottles. Of course, the packaging box 200 can also be the outer packaging of other items, without special structural details here. Specifically, the packaging box 200 includes a face paper 204 and a cardboard 205. The face paper 204 and the base plate 202 have been pre-grooved and laminated using a covering machine. In its unformed state, the packaging box 200 has five continuous and connected packaging sides 201 and a base plate 202. Among the five packaging sides 201, the middle three are composite adhesives of the face paper 204 and the cardboard 205, the leftmost packaging side 201 is the face paper 204, and the rightmost packaging side 201 is the cardboard 205.

[0052] This utility model embodiment provides a packaging box forming device 100, such as... Figures 1 to 16 As shown, the packaging box forming equipment 100 includes a conveying mechanism 2 and a packaging box forming device 4.

[0053] The packaging box forming device 4 includes a mold 11 and two folding devices 41; the two folding devices 41 are arranged on opposite sides of the mold 11 in a first direction. Specifically, when forming the packaging box 200, the packaging side 201 of the unformed packaging box 200 in the middle is attached to the bottom of the mold 11. The two folding devices 41 are arranged on opposite sides of the mold 11 along the first direction, specifically the length direction of the mold 11. With the packaging side 201 in the middle as a reference, the two left and right packaging sides 201 are moved to the left and right sides of the mold 11 by the two folding devices 41. Under the action of inertia, the face paper 204 and cardboard 205 connected to the left and right packaging sides 201 are flipped and thrown to the top surface of the mold 11. After the face paper 204 and cardboard 205 are pressed together, a complete packaging side 201 is formed, so that the four packaging sides 201 of the packaging box 200 can be sealed.

[0054] The conveying mechanism 2 includes a first conveying device 21, a transfer device 22, and a second conveying device 23; the first conveying device 21 moves along a second direction, the second conveying device 23 moves along the first direction, and the mold 11 is set on the conveying trajectory of the second conveying device 23, the first direction and the second direction intersect; the conveying trajectory of the transfer device 22 intersects with the conveying trajectory of the first conveying device 21 and the conveying trajectory of the second conveying device 23. Specifically, the unformed packaging box 200 is fed to the first conveying device 21, which conveys the unformed packaging box 200. The second direction can be the direction perpendicular to the length direction of the mold 11, such as the width direction of the mold 11, or the direction intersecting the length direction of the mold 11. It only needs to be different from the length direction of the mold 11, and there are no special restrictions here. When the first conveying device 21 conveys the unformed packaging box 200 to the position, the unformed packaging box 200 is transferred to the second conveying device 23 by the transfer device 22. Then, the second conveying device 23 conveys the unformed packaging box 200 along the first direction, that is, the length direction of the mold 11, to the corresponding position of the mold 11 for paper box forming.

[0055] Therefore, it is understandable that the conveying mechanism 2, by setting up a first conveying device 21 and a second conveying device 23, with the two conveying devices having different conveying directions and being smoothly transferred through the transfer device 22, can achieve transmission in different directions, optimize space, effectively save space, and reduce the space occupied by the equipment. Furthermore, the second conveying device 23 is set to convey along the first direction of the mold 11, thereby effectively avoiding interference between the second conveying device 23 and the two folding devices 41 when conveying the unformed packaging box 200 to the bottom of the mold 11, thus effectively avoiding the risk of collision between the folding device 41 and the conveying mechanism 2 when the packaging box 200 is folded.

[0056] Specifically in this embodiment, such as Figure 4 and Figure 16 As shown, the mold 11 is a long strip plate structure; the first direction is the length direction of the mold 11, and the second direction is the width direction of the mold 11. Understandably, the mold 11 is a long strip plate structure, capable of adapting to the shape of a conventional long strip packaging box 200. Two folding devices 41 are arranged on opposite sides of the mold 11 along its length direction (first direction) to perform side folding of the packaging box 200 from the side of the mold 11. The first conveying device 21 conveys the unformed packaging box 200 along the width direction of the mold 11 (second direction), that is, from the lateral direction of the mold 11 to an area close to the mold 11. However, the first conveying device 21 is not directly facing the mold 11. Then, it is transferred to the second conveying device 23, which continues to convey the box along the length direction of the mold 11 (first direction) to the location of the mold 11. Since the conveying path of the second conveying device 23 is parallel to the long axis (length direction) of the mold 11, rather than spanning the mold 11 (width direction), its conveying components and driving components are mainly distributed in the end area of ​​the mold 11. The folding device 41 operates primarily on the sides and above the mold 11. Specifically, the second conveying device 23 operates at both ends of the mold 11, while the folding device 41 operates on both sides. The movement trajectories of the two devices are essentially orthogonal or staggered in three-dimensional space. This ensures that when the folding device 41 performs its folding action, its movement trajectory avoids the running path and structure of the second conveying device 23, effectively preventing interference between them and avoiding the risk of collision between the folding device 41 and the conveying mechanism 2 when the packaging box 200 is folded.

[0057] In some embodiments, such as Figure 3As shown, the first conveying device 21 includes a power source, a conveyor belt 211, and a limiting plate 212; the power source is connected to the conveyor belt 211 and drives the conveyor belt 211 to move along the second direction; the limiting plate 212 is disposed at the conveying end of the conveyor belt 211. The packaging box 200 is transported by a conveyor belt 211, with a limiting plate 212 at the end of the conveyor belt 211. The continuous forward momentum provided by the conveyor belt 211 allows the box to maintain its inertia and automatically position itself against the limiting plate 212 upon arrival at its destination, thus correcting any misalignment or displacement of the packaging box 200. This ensures that the packaging box 200 is already shaped according to the mold 11 before entering the second conveyor device 23, allowing it to precisely match the positioning reference of the mold 11 upon entering the forming station. Furthermore, the packaging box 200 is automatically shaped by the limiting plate 212 during transport by the conveyor belt 211, eliminating the need for a complete stop or transfer to a dedicated forming station before shaping, thereby improving transport efficiency and stability. Specifically, the power source can be a conventional motor and power transmission components such as drive wheels, which work together to propel the conveyor belt 211. This will not be described in detail here.

[0058] In some embodiments, such as Figure 5 As shown, the second conveying device 23 includes a conveying drive device 231 and a conveying frame 232. The conveying drive device 231 is connected to the conveying frame 232 and drives the conveying frame 232 to move along the first direction. The conveying frame 232 is provided with an adsorption hole 2321. This adsorption hole 2321 can be connected to an external negative pressure via a pipe, thereby creating a negative pressure at the adsorption hole 2321 of the conveying frame 232. This firmly adsorbs the packaging box 200 onto the conveying frame 232, preventing it from falling or shifting. When the box is in place, the negative pressure is turned off to release the packaging box 200. The operation is simple and convenient. It can be understood that by adsorbing and fixing the packaging box 200 through the adsorption hole 2321 on the conveying frame 232, horizontal displacement or angular deflection of the packaging box 200 during conveying is effectively prevented. This ensures that the position of the packaging box 200 after entering the forming station can accurately match the positioning reference of the mold 11, thereby effectively avoiding problems such as uneven edges, folded twisting, and pressing failure, and improving the finished product qualification rate.

[0059] In some embodiments, the conveyor frame 232 includes a connector 2322 and at least two support plates; the conveying drive device 231 is connected to the connector 2322, and each of the support plates is arranged side by side on the connector 2322, with the adsorption hole 2321 provided on the upper surface of at least one of the support plates. It is understood that since the unformed packaging box 200 is in an unfolded state, it has a large width. By arranging multiple support plates side by side along the width direction of the unformed packaging box 200, and by having multiple support plates jointly support the unformed packaging box 200, and each support plate is provided with the adsorption hole 2321, on the one hand, the unformed packaging box 200 can be well supported, effectively preventing partial collapse of the unformed packaging box 200; on the other hand, the multiple adsorption holes 2321 allow the negative pressure to act more comprehensively on all corners of the bottom surface of the packaging box 200, improving adsorption stability and anti-displacement ability, and effectively preventing the packaging box 200 from sliding, twisting, or shifting.

[0060] In some embodiments, the support plate includes a first support plate 2324, a second support plate 2325, and a third support plate 2326; the first support plate 2324 and the third support plate 2326 are disposed on opposite sides of the second support plate 2325, and the first support plate 2324 and the third support plate 2326 are respectively slidably mounted on the connector 2322 and can be close to or away from the second support plate 2325. Specifically, the first support plate 2324 and the third support plate 2326 are both mounted on the precision linear slide rail 2323 and slidably rest on the connector 2322. The first support plate 2324 and the third support plate 2326 can be manually adjusted in position and locked after adjustment by a locking device such as a handle-operated eccentric cam lock, bolt locking block, or quick-release clamp, or mechanically fixed by positioning holes and pins to ensure positional accuracy and rigidity. This allows the distance between the first support plate 2324 and the second support plate 2325 to be adjusted according to the specifications of the unformed packaging box 200 it carries, so that it precisely matches the width dimension of the unformed packaging box 200 it carries. Of course, in other embodiments, the first support plate 2324 and the third support plate 2326 can also each be driven by a power source such as a linear motor or electric push rod to adjust the distance between them and the second support plate 2325, without any particular limitation.

[0061] It should be noted that, as Figure 4 and Figure 8As shown, the folding device 41 includes a side swing drive device 411 and a side fold swing rod 412. The side swing drive device 411 is connected to the side fold swing rod 412 and drives the side fold swing rod 412 to swing up and down on the side of the mold 11. When the unformed packaging box 200 is transported to the mold 11 of the packaging box forming device 4, the side swing drive device 411 drives the side fold swing rod 412 to swing upward, thereby driving the packaging sides 201 on the left and right sides of the mold 11 to fold upward. Specifically, in this embodiment, at least two side fold swing rods 412 are provided. Each side fold swing rod 412 is connected to the side swing drive device 411 through a rotating shaft. The side swing drive device 411 drives each side fold swing rod 412 to swing up and down through the rotating shaft. When the two packaging sides 201 of the unformed packaging box 200 are driven by the side folding swing rod 412 to adhere to the left and right sides of the mold 11, the face paper 204 and cardboard 205 connected to the two packaging sides 201 of the unformed packaging box 200 can be flipped and thrown towards the top surface of the mold 11 under the action of inertia. When the three support plates enter the lower part of the mold 11, the second support plate 2325 is located between the rotation axes of the two folding devices 41, while the first support plate 2324 and the third support plate 2326 are located outside the side folding swing rod 412. Therefore, the conveying mechanism 2 can be well avoided from interfering with the folding device 41, and the structure can be made compact.

[0062] In some embodiments, multiple adsorption holes 2321 are provided; each adsorption hole 2321 is spaced apart along the length direction of the support plate. Understandably, by providing multiple adsorption holes 2321 on the support plate, the total area of ​​the negative pressure effect can be expanded, thereby covering the area along the length direction of the packaging box 200. This allows the negative pressure effect to act more comprehensively on all corners of the bottom surface of the packaging box 200, improving adsorption stability and anti-displacement ability, and effectively preventing the packaging box 200 from sliding, twisting, or shifting.

[0063] In some embodiments, such as Figure 15As shown, the transfer device 22 includes a transfer drive device 221 and an adsorption element 222. The transfer drive device 221 is connected to the adsorption element 222 and drives the adsorption element 222 to move between the conveyor belt 211 and the conveyor frame 232. Specifically, the transfer device 22 may include a linear motor and a lifting motor, which work together to move the adsorption element 222 in a two-dimensional space. The linear motor drives the adsorption element 222 to move quickly and smoothly between the conveyor belt 211 and the conveyor frame 232, while the lifting motor, such as a screw motor or an electric cylinder, drives the adsorption element 222 to move up and down, thereby realizing the gripping and release of the unformed packaging box 200, and thus smoothly transferring the unformed packaging box 200 from the conveyor belt 211 to the conveyor frame 232. Specifically, in this embodiment, the adsorption component 222 includes a fixing plate 2221 and a plurality of suction cups 2222 disposed on the fixing plate 2221. The suction cups 2222 can be connected to external negative pressure. Through the cooperation of the plurality of suction cups 2222, the negative pressure formed by the suction cups 2222 can act more comprehensively on all positions of the packaging box 200, improve adsorption stability and anti-displacement ability, and effectively prevent the packaging box 200 from slipping.

[0064] In some embodiments, such as Figure 6As shown, the packaging box forming device 4 further includes a first folding mechanism 42, a second folding mechanism 43, and a straightening mechanism 46; the first folding mechanism 42 and the second folding mechanism 43 are disposed on opposite sides of the mold 11 in a first direction and located above the mold 11; the straightening mechanism 46 includes a straightening drive device 461 and a toggle member 462; the straightening drive device 461 is disposed on the first folding mechanism 42, the straightening drive device 461 is connected to the toggle member 462 and drives the toggle member 462 to reciprocate along the first direction, and the toggle member 462 is at least partially externally located on the side of the first folding mechanism 42 near the second folding mechanism 43. Understandably, during the forming process of the packaging box, the packaging side 201 of the unformed packaging box located in the middle is attached to the bottom of the mold 11. Then, the two packaging sides 201 of the unformed packaging box 200 are attached to the left and right sides of the mold 11 by the two folding devices 41. Under the action of inertia, the face paper 204 and cardboard 205 connected to the two packaging sides 201 of the unformed packaging box 200 are flipped and thrown to the top surface of the mold 11. At this time, the first folding mechanism 42 presses the cardboard 205 toward the top surface of the mold 11, and then the second folding mechanism 43 presses the face paper 204 toward the position of the cardboard 205 to press the face paper 204 and the cardboard 205 together to form a complete packaging side 201, thereby sealing the four packaging sides 201 of the packaging box 200. After the first folding mechanism 42 is pressed and before the second folding mechanism 43 is pressed, there is a slight misalignment at the corners of the face paper 204 relative to the three packaging sides 201. That is, the edge of the face paper 204 is not precisely aligned with the preset fold line of the packaging side 201, resulting in a slight offset. This can easily lead to the final corners not presenting a straight and crisp geometric shape, possibly resulting in wrinkles, bulges, collapses, or obvious uneven edges, reducing the finished product qualification rate. The alignment drive device 461 drives the actuating component 462 to move forward in the first direction. The front end of the actuating component 462 directly contacts and acts on the corner area of ​​the face paper 204 with slight misalignment, which can move the misaligned corner of the face paper 204, so that the originally misaligned edge of the face paper 204 is aligned with the preset fold line of the packaging side 201, reducing the sealing failure caused by corner misalignment, thereby improving the finished product qualification rate and appearance quality of the packaging box 200.

[0065] In some embodiments, such as Figure 7As shown, the actuating member 462 has a plate-like structure and is vertically disposed on the surface of the first folding mechanism 42. It can be understood that the plate-like actuating member 462 being vertically disposed on the surface of the first folding mechanism 42 means that the plate surface of the actuating member 462 is perpendicular to the surface of the first folding mechanism 42. Therefore, when the actuating member 462 is moved forward, its flat front surface can completely cover and conform to the corner areas of the face paper 204 where there are slight misalignments, increasing the contact area and thus evenly distributing the applied corrective force, preventing excessive local pressure that could cause indentations, tears, or new deformations in the face paper 204.

[0066] In some embodiments, the actuating member 462 includes a first actuating plate 4621 and a second actuating plate 4622. The second actuating plate 4622 is connected to the straightening drive device 461 through the first actuating plate 4621, and the second actuating plate 4622 is inclined relative to the first actuating plate 4621 towards the side away from the surface of the first folding mechanism 42. Understandably, when the actuating member 462 is disposed on the first folding mechanism 42, the second actuating plate 4622 will deflect upward at a certain angle, thereby reducing the structural space occupied while also creating a certain actuation space in height, thus accommodating the straightening operation of packaging boxes 200 of different sizes and increasing the contact area with the packaging box 200. Specifically, in this embodiment, the end of the second actuating plate 4622 closest to the first actuating plate 4621 is the first end, and the end of the second actuating plate 4622 away from the first actuating plate 4621 is the second end. The width of the plate surface of the second actuating plate 4622 gradually decreases in the direction of extension from the first end to the second end, thereby forming a structure similar to a tapered trapezoid or cone, which can further reduce the structural volume and ensure sufficient contact area with the packaging box 200.

[0067] In some embodiments, such as Figure 6As shown, the first folding mechanism 42 includes a first folding drive device 421, a sliding block 422, a guide rail 423, and a folding plate 424. The guide rail 423 is inclined relative to the mold 11. The first folding drive device 421 drives the sliding block 422 to reciprocate along the guide rail 423. The folding plate 424 is connected to the sliding block 422. Understandably, the folding plate 424 is used to press the cardboard 205. Specifically, the first folding drive device 421 drives the sliding block 422 to move along the guide rail 423, thereby causing the folding plate 424 to move downwards and towards the middle position of the top of the mold 11. Under the action of the folding plate 424, the cardboard 205 is flattened and contacts the top surface of the mold 11. The second folding mechanism 43 includes a second folding drive device 431 and a brush component 432; wherein the brush component 432 can be a brush strip or a brush roller, and the second folding drive device 431 is connected to the brush component 432 and drives the brush component 432 to move closer to or away from the mold 11 along the surface extension direction of the top of the mold 11. After the cardboard 205 of the unformed packaging box 200 is pressed down, the second folding drive device 431 drives the brush component 432 to rotate towards the mold 11, thereby pressing the face paper 204 onto the cardboard 205, and sealing the four packaging sides 201 of the packaging box 200. The specific workflow is as follows: During operation, when one packaging side 201 of the unformed packaging box 200 is already under the mold 11, the two sets of folding devices 41 fold the packaging sides 201 on the left and right sides of the mold 11 to the left and right sides of the mold 11, respectively. The two downward folding mechanisms fold the cardboard 205 and the face paper 204 on the top surface of the mold 11 to the top surface of the mold 11 to complete the cover. The second downward folding mechanism 43 can cooperate with the rotation of the mold 11 to cover the face paper 204. That is, when the mold 11 moves to the next station by rotation, the brush part 432 is just performing the covering work.

[0068] In some embodiments, such as Figure 1 and Figure 13 As shown, the packaging box forming equipment 100 also includes a rotation drive device, a rotating seat 13, a bottom plate feeding device 3, a compaction and side folding device 5, and a release device 6;

[0069] The rotation drive device is connected to the rotating seat 13 and drives the rotating seat 13 to rotate around its own circumference; the mold 11 is set on the rotating seat 13; the bottom plate feeding device 3, the packaging box forming device 4, the compaction side folding device 5 and the release device 6 are arranged at intervals along the circumference of the rotating seat 13. The rotation drive device drives the mold 11 to rotate sequentially to the bottom plate feeding device 3, the packaging box forming device 4, the compaction side folding device 5 and the release device 6 to perform bottom plate 202 feeding, folding, compaction and edge wrapping and demolding.

[0070] The rotating drive device, such as a rotary motor, drives the rotating base 13 to rotate intermittently. The rotation direction of the rotating base 13, viewed from above, can be either clockwise or counterclockwise; no particular restriction is placed here. The end of the mold 11 furthest from the rotating base 13 is the outer end of the mold 11, corresponding to the position of the bottom plate 202 of the packaging box 200. The end of the mold 11 closest to the rotating base 13 is the inner end of the mold 11, corresponding to the position of the opening of the packaging box 200. The four sides of the mold 11 (top, bottom, left, right) correspond to the four packaging sides 201 of the packaging box 200. Therefore, the mold 11 can be rotated to the bottom plate feeding device 3 first, and the bottom plate 202 can be transferred to the outer end of the mold 11. Then, the mold 11 can be rotated to the packaging box forming device 4. At this time, the conveying mechanism 2 just transports the unformed packaging box 200 to the bottom of the mold 11. In order to make the unformed packaging box 200 fit with the bottom of the mold 11, the mold 11 can be moved downward by setting a lifting drive device to make the mold 11 contact the unformed packaging box 200. That is, the unformed packaging box 200 is kept still, and only the mold 11 is moved to make the two in a contact fit state. Alternatively, an ejector plate can be set to eject the unformed packaging box 200 to the bottom side of the mold 11 so that the two fit together. Then, the four sides of the packaging box 200 are folded and sealed together by the folding device 41 and the downward folding mechanism to form a box shape. At least one side of the side folding edge 203 on the upper, lower, left and right sides of the corresponding position of the bottom plate 202 is brushed towards the middle of the bottom plate 202 by the side folding mechanism. After the operation is completed, the mold 11 is rotated to the pressing side folding device 5 to brush the remaining side folding edges 203 on the upper, lower, left and right sides of the corresponding position of the bottom plate 202 towards the middle of the bottom plate 202. The four packaging sides 201 of the packaging box 200 are pressed against the top and bottom of the mold 11 to obtain the formed packaging box 200. After the operation is completed, the mold 11 is rotated to the release device 6 to demold the formed packaging box 200 from the mold 11.

[0071] Specifically in this embodiment, such as Figure 16 As shown, four molds 11 are provided, and the rotating base 13 is a turntable structure. The four molds 11 are evenly arranged around the turntable structure along its circumferential direction. After the first mold 11 completes the loading process of the base plate 202, the turntable structure rotates 90 degrees according to a preset program, precisely positioning the mold 11 at the station of the packaging box forming device 4. At the same time, the subsequent molds 11 immediately enter the base plate 202 loading station to begin a new round of loading operations. This design enables parallel processing of various processes, allowing the four key processes of base plate 202 loading, folding and forming, pressing and binding, and demolding to be carried out simultaneously.

[0072] It should be noted that, as Figure 14As shown, the packaging box forming equipment 100 also includes an edge-wrapping mechanism 7, which is located on one side of the conveyor belt 211. When the unformed packaging box 200 is fed to the conveyor belt 211, the edge-wrapping mechanism 7 first wraps the multiple side folds 203 of the unformed packaging box 200 corresponding to the box opening inward. Specifically, the edge-sealing mechanism 7 includes a support plate 71, a pressing plate 72, a pressing drive device 73, an edge-pressing plate 74, a lifting plate 75, a first edge-pressing drive device 76, and a second edge-pressing drive device 77. The support plate 71 is disposed on one side of the conveyor belt 211 and is flush with the conveying surface of the conveyor belt 211. The pressing drive device 73 is connected to the pressing plate 72 and drives the pressing plate 72 to move up and down above the conveying surface of the conveyor belt 211. The pressing drive device 73, like a lifting motor, drives the pressing plate 72 downward to abut against the support plate 71 to press down the unformed packaging box 200 conveyed to the conveyor belt 211, thereby fixing the unformed packaging box 200. The first edge-pressing drive device 76... 6. If the lifting motor is connected to the lifting plate 75 and drives the lifting plate 75 to rise and fall on the side of the conveyor belt 211, the pressing plate 74 is rotatably mounted on the lifting plate 75 via a swing arm. Specifically, the pressing plate 74 is rotatably mounted on the swing arm via a first rotating shaft, and the swing arm is rotatably mounted on the lifting plate 75 via a second rotating shaft. The second pressing drive device 77 is connected to the pressing plate 74 and drives the pressing plate 74 to move back and forth along the direction intersecting the conveying trajectory of the conveyor belt 211. Therefore, the swing arm is driven to swing toward the conveying surface of the conveyor belt 211, and at the same time, the pressing plate 74 also rotates downward under the action of the swing arm, so that the pressing plate 74 has downward pressure to compact the edge during edge wrapping. During the pressing and binding process, the pressing drive device 73 first drives the pressing plate 72 to move downwards and press the unformed packaging box 200 onto the pallet 71. Then, the first pressing drive device 76 drives the lifting plate 75 to move upwards, which in turn drives the pressing plate 74 to move upwards and fold the side folds 203 of the three packaging sides 201 of the unformed packaging box 200 corresponding to the box opening position upwards to complete the folding. After the folding is completed, the second pressing drive device 77 drives the pressing plate 74 to move towards the conveyor belt 211, thus driving the pressing plate 74 to rotate downwards, thereby folding the folded side folds 203 inwards, and the pressing plate 74 presses downwards to complete the binding.In addition, the edge-sealing mechanism 7 may also include a first linear drive device and a second linear drive device, wherein the pallet 71 and the second linear drive device are mounted on the first linear drive device, such as a linear motor. The first linear drive device drives the pallet 71 to move closer to or further away from the conveyor belt 211 along the width direction of the conveyor belt 211, thereby adjusting the position of the pallet 71 relative to the conveyor belt 211 according to the specifications of the unformed packaging box 200. The pressing drive device 73 and the first edge-pressing drive device 76 are mounted on a bracket, which is mounted on the second linear drive device. The second linear drive device drives the bracket to move along the conveying direction of the conveyor belt 211, thereby adjusting the edge-pressing position according to the specifications of the unformed packaging box 200.

[0073] In some embodiments, such as Figure 10 and Figure 11As shown, the mold 11 is a long strip mold, and the side of the mold 11 away from the rotating seat 13 is provided with an air hole, that is, the outer end of the mold 11 is provided with an air hole; the bottom plate feeding device 3 includes a bottom plate discharge mechanism 31, a swing drive mechanism 32, and a swing plate 33; the bottom side of the bottom plate discharge mechanism 31 is provided with a discharge port; the swing drive mechanism 32 is connected to the swing plate 33 and drives the swing plate 33 to swing in a first position and a second position. When the swing plate 33 is in the first position, the swing plate 33 abuts against the side of the mold 11 away from the rotating seat 13. When the swing plate 33 is in the second position, the swing plate 33 is arranged along the discharge direction of the discharge port of the bottom plate discharge mechanism 31. Specifically, the first position can be in a vertical direction, and the second position can be in a horizontal direction, that is, the first position and the second position can be in intersecting or perpendicular directions, without any particular limitation. The bottom plate discharge mechanism 31 can be a drive structure that can automatically transport the stacked bottom plates one by one to the swing plate 33. For example, it can use a suction cup to pick up the bottom plates 202 one by one to the swing plate 33. Or, in this embodiment, the bottom plate discharge mechanism 31 includes a storage tank, a push rod and a push driving device. The bottom side of the storage tank is provided with a discharge port that matches the thickness of the bottom plate 202. The push rod is movably disposed in the storage tank along the discharge direction of the discharge port. The push driving device is connected to the push rod and pushes the bottom plate 202 stacked at the bottom in the storage tank out of the discharge port. When it is necessary to feed the bottom plate 202, the swing drive mechanism 32 first drives the swing plate 33 to the second position to contact the bottom of the storage tank and adapt to the discharge direction of the discharge port. Then, the drive device drives the push rod to move and push the bottom plate 202 stacked at the bottom in the storage tank out of the discharge port to the swing plate 33. It should be noted that the push rod is provided with a push-out part to hold the bottom plate 202 above the storage tank to prevent it from falling. The next bottom plate can continue to fall when the push rod has finished pushing and retreated into the storage tank. Then, the swing drive mechanism 32 drives the swing plate 33 to swing to the first position so that the bottom plate 202 on the swing plate 33 is transferred to the outer end of the mold 11, and the mold 11 holds the bottom plate 202. In this embodiment, when the swing plate 33 is in the second position, it has a downward inclined structure relative to the bottom of the storage tank so that the pushed bottom plate 202 can move along the inclined surface to the preset position of the swing plate 33 under its own gravity. Specifically, the swing plate 33 is driven by the swing drive mechanism 32 (such as by a cylinder) to rotate back and forth by 60 to 90 degrees, and the swing plate 33 is provided with a groove or stepped structure to accommodate the positioning base plate 202.In addition, the base plate feeding device 3 can also be equipped with a buffer. The opposite ends of the buffer are connected to the swing plate 33 and the mounting base 1, respectively. The mounting base 1 can be a support for supporting components such as the rotating seat 13, the mold 11, the conveying mechanism 2, the base plate feeding device 3, the packaging box forming device 4, the compaction and folding device 5, and the release device 6. The buffer is used to prevent strong collisions when the swing plate 33 flips.

[0074] In some embodiments, such as Figure 9 As shown, the packaging box forming device 4 also includes a first side folding mechanism 44 and a second side folding mechanism 45. The first side folding mechanism 44 includes a side folding drive device, a swing arm, and a brush. The side folding drive device is connected to the brush through the swing arm. The side folding drive device drives the swing arm to drive the brush to press the side folded edge 203 towards the bottom plate 202 from the right side of the mold 11. The second side folding mechanism 45 includes a side folding drive device and a brush. The brush can be a brush strip or a brush roller. The side folding drive device drives the brush to press the side folded edge 203 towards the bottom plate 202 from the upper side of the mold 11. That is, when performing the cover operation of the face paper 204, the side folded edge 203 can be pressed towards the bottom plate 202 through the two side folding mechanisms.

[0075] In some embodiments, such as Figure 12 As shown, the compaction side folding device 5 includes a pressing device, a third side folding mechanism 53, and a fourth side folding mechanism 54; the pressing device includes a pressing drive device 51 and two pressure plates 52 connected to the pressing drive device 51. When the mold 11 is transferred from the packaging box forming device 4 to the compaction side folding device 5, the mold 11 is positioned between the two pressure plates 52 and pressed by the pressure plates 52. The third side folding mechanism 53 and the fourth side folding mechanism 54 are located on the other two sides of the outer end of the mold 11. The two pressure plates 52 can be driven to move closer or further apart by the same pressing drive device 51, such as a cylinder, or the two pressure plates 52 can be controlled to move closer or further apart by two separate pressing drive devices 51, thereby compacting the packaging sides 201 of the packaging box 200 below and above the mold 11. The third side folding mechanism 53 and the fourth side folding mechanism 54 are located on the other two sides of the outer end of the mold 11. Both the third side folding mechanism 53 and the fourth side folding mechanism 54 include a side folding drive device and a brush. That is, the side folding drive device drives the brush to brush the side folded edges 203 towards the bottom plate 202 from the lower and left sides of the mold 11 to compact the side folded edges 203. In other words, when performing the cover operation of the face paper 204, the four side folding mechanisms can be used to compact the four side folded edges 203 towards the bottom plate 202.

[0076] In some embodiments, such as Figure 13 As shown, the detachment device 6 includes a detachment drive device 61 and a push-away device 62; the push-away device 62 includes a connecting frame and two hook drive devices 621 and two hook bodies 622 disposed on the connecting frame; the two hook bodies 622 are disposed on opposite sides of the width direction of the mold 11, and the hook drive devices 621 are connected to the hook bodies 622 and drive the hook bodies 622 to move closer or further away from each other along the width direction of the mold 11, and the detachment drive device 61 is connected to the connecting frame and drives the connecting frame to move along the length direction of the mold 11. Understandably, the formed packaging box 200 needs to be detached from the mold 11. The hook driving device 621 drives two hook bodies 622 to move closer or further apart along the width direction of the mold 11 to hook or release the opening of the packaging box 200. Specifically, the hook driving device 621 can be, for example, a cylinder or a linear electrode, etc. There are no special restrictions here. There can be two hook driving devices 621, which drive the two hook bodies 622 to move closer to each other respectively. Alternatively, there can be only one hook driving device 621, which drives the two hook bodies 622 to move simultaneously through a conventional transmission connection structure. There are no special restrictions here. When the two hook bodies 622 extend, they cooperate to hook the opening of the packaging box 200. The hook body 622 can be set in an L-shape. When the mold 11 rotates to the position of the release device 6 and the packaged box 200 is released from the mold 11, the two hook bodies 622 on the connecting frame are driven by the release drive device 61, such as a cylinder or a linear motor, to move along the length of the mold 11 towards the inside of the mold 11 to the opening of the packaged box 200. After moving into position, the two hook bodies 622 extend and hook the opening of the packaged box 200. The release drive device 61 drives the hook bodies 622 to move towards the outside of the mold 11 to remove the packaged box 200 from the mold 11. After removal, the hook bodies 622 extend and retract to wait for the next action. It should be noted that the air holes provided on the mold 11 can be switched to blowing or suction mode. When the mold 11 is in suction mode corresponding to the base plate feeding device 3, packaging box forming device 4, and compaction side folding device 5, it can firmly hold the packaging box 200 to the mold 11. When it is in blowing mode or stops blowing when corresponding to the release device 6, the packaging box 200 can be demolded smoothly.
