Description

Technical Field

[0001] This utility model relates to a paper box forming and assembly machine. Background Technology

[0002] Paper boxes are commonly used for packaging, such as wine boxes and gift boxes. Among them, book-shaped boxes are one of the main paper box structure types. These types of paper boxes (such as book-shaped boxes) have a panel shell part and a box body part.

[0003] When manufacturing and assembling this type of cardboard box, the box body needs to be assembled and connected to the panel shell. During assembly, the panel shell can be laid flat on a (horizontal) conveyor belt for transport, and then the blank box (box body) is placed on the panel shell on the conveyor belt. This assembly method is relatively simple and lacks variety. In addition, in this assembly method, only the bottom of the blank box (box body) and the shell (top surface) can be fitted and connected. Moreover, this method of directly assembling the box body and the shell requires stocking the boxes or setting up cardboard box forming equipment to produce the boxes. For the user manufacturer, stocking the boxes will incur procurement, transportation, and warehousing costs, and the cost is relatively high, and it occupies a lot of space. After producing the boxes using a cardboard box forming machine, additional collection, transfer, and storage of the boxes are also required. Furthermore, the entire cardboard box manufacturing process requires cardboard box forming equipment, shell forming machines, assembly machines, etc.

[0004] Paper box forming equipment includes, for example, top and bottom box forming equipment (including corner attaching machines, etc.), or paper box forming machine and mold device (CN213767411U), paper box forming machine (CN220280644U), paper box forming equipment (CN218430184U), etc. These can employ multi-station intermittent rotating horizontal paper box molds. These horizontal paper box molds can also have additional lifting and lowering actions, cooperating with other structures at each station for forming operations. For example, they can be used with a box body enclosure device (or side forming mechanism such as CN204640926U, or CN219968976U frame forming mechanism, etc.) to enclose the semi-finished shell (including slotted and partitioned multi-part cardboard) on the horizontal paper box mold to form a frame, which can be connected to the bottom plate (i.e., the box bottom) on the horizontal paper box mold. Utility Model Content

[0005] In view of the technical problems existing in the background art, the present utility model aims to provide a paper box forming and assembly machine that can not only complete the forming of the box body (i.e. the main structure) of the paper box, but also complete the assembly and connection of the box body and the panel shell of the paper box.

[0006] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a paper box forming and assembly machine, including a rotary mold device, a bottom plate mold assembly mechanism, a box body forming mechanism that forms a frame around a long strip upper mold and connects to the bottom plate, a panel and shell adhesive box body assembly mechanism, and a paper box demolding mechanism. The rotary mold device includes a horizontal paper box mold, and is equipped with at least a first mold stopping position, a second mold stopping position, a third mold stopping position, and a fourth mold stopping position. These positions are arranged circumferentially. The bottom plate mold assembly mechanism is connected to the first mold stopping position. The box body forming mechanism that forms a frame around a long strip upper mold and connects to the bottom plate is connected to the second mold stopping position. The panel and shell adhesive box body assembly mechanism is connected to the third mold stopping position. The paper box demolding mechanism is connected to the fourth mold stopping position.

The push-insertion components use direct-push reciprocating insert plates. The push-insertion drive device is located on the back of the first bearing part. The push-insertion path of the push-insertion components is orthogonal to the bearing plane of the first bearing part. The push-insertion drive device is connected to the assembly tilting frame. The first bearing part has a folding plate channel for the push-insertion components to pass through the push-insertion folding plate. The push-insertion components are relatively adjustable in left and right positions on the assembly tilting frame.

The left side of the horizontal cardboard box mold... The right side is provided with plate receiving recesses, which are respectively for the left and right sides of the base plate to be folded in. The base plate material hopper connected to the base plate feeding station includes left and right side plates and a discharge front stop. The bottom of the base plate material hopper is provided with a material support component. A single plate output gap is left between the discharge front stop and the material support component below. The base plate conveying device includes a plate discharge pusher, which is connected to the plate discharge pushing power component. The plate discharge pusher is located at the bottom of the base plate material hopper. The first bearing part on the assembly flipping frame located at the base plate feeding station cooperates with the material support component for feeding. The material support component is a material support plate. When cooperating with the feeding connection, the material support plate is higher than the first bearing part or the material support plate is flush with the first bearing part. The material support plate is flat, and the first bearing part is flat. The horizontal paper box mold is arranged to revolve around the vertically arranged main rotating shaft. The horizontal paper box mold is connected to the main rotating shaft and is distributed along the circumference of the main rotating shaft. The horizontal paper box mold revolves and stops intermittently at each mold stopping position.

[0011] For example, the box forming mechanism that connects the box bottom plate to the upper mold of the long strip shell also includes a long strip shell feeding device, and a long strip shell pre-adhesion device including a pre-adhesion component. The pre-adhesion component is arranged above the conveying path of the shell conveying component. The shell conveying component is connected to the long strip shell feeding device of the box body. The shell conveying component is connected to the enclosure device of the long strip shell overlapping and enclosing mold. The long strip shell pre-adhesion device is set between the long strip shell feeding device of the box body and the enclosure device.

[0012] For example, the long strip shell feeding device, the long strip shell pre-gluing device, and the enclosure device are arranged in sequence along a straight line. The enclosure device includes a clamping upper mold mechanism, which includes a base. The base is provided with a tray and left and right side flaps. The left and right side flaps are arranged on the left and right sides of the tray. The second mold stopping position is correspondingly matched with the tray below. A lifting horizontal paper box mold and / or a lifting tray are used. The enclosure device also includes a box body upper side forming mechanism, which is arranged above the second mold stopping position.

[0013] In addition, the upper mold clamping mechanism is connected to the shell conveying component, and a shell transfer robot is also connected between the shell conveying component and the enclosure device. The shell transfer robot is connected and positioned between the upper mold clamping mechanism and the shell conveying component. The base of the upper mold clamping mechanism is located below the second mold stopping position. The base is a reciprocating type, with a receiving position on the outer side and an upper mold clamping position on the inner side. The base moves and switches between the receiving position and the upper mold clamping position. The base is connected to the shell transfer robot at the receiving position. The upper mold position is connected to the second mold position, and the horizontal cardboard box mold at the second mold position is correspondingly matched with the tray below; the upper side forming mechanism includes an upper side plate folding component and a front and rear overlapping mounting component; the front and rear overlapping mounting component is connected to the transverse shifting drive device, and the front and rear overlapping mounting component is also connected to the lifting mounting drive device; the pre-adhesive component includes an adhesive component at the overlapping joint of the long strip shell and an adhesive component at the joint of the long strip shell corresponding to the outside of the folded plate part on the left and right sides of the bottom plate.

[0014] For example, the shell feeding station, the shell gluing station, and the shell flipping and assembly station are arranged in a straight line.

[0016] Further optimization is possible: the left and / or right sides of the second bearing section are respectively provided with rollers for folding and rolling the material, and the left and / or right rollers are respectively positioned on the left and / or right sides of the horizontal cardboard box mold at the stopping position of the third mold.

[0017] The roller is connected to the linear reciprocating drive component, and the roller and the linear reciprocating drive component are connected to the flip assembly frame. The linear reciprocating drive component is located on the back of the second bearing part.

[0018] In addition, the forward feeding component uses a feeding belt and / or a feeding pusher; the left and right sides of the forward feeding component are also equipped with left and right side stops for limiting the feeding of the casing. The glue application device on the upper side of the casing includes a transverse glue application component and / or a longitudinal glue application component, and the glue application device on the upper side of the casing is located above the forward feeding component. The flip assembly frame is connected to the second flip shaft, the axis of the second flip shaft is set horizontally, and the flip assembly frame is connected to the forward and backward flipping drive device. The outer side of the horizontal carton mold at the third mold stopping position mates with the second support part when it is flipped into place by the flip assembly frame. The horizontal cardboard box mold is positioned at the third mold stopping position to receive the corresponding shell flipping assembly device. The outer surface of the horizontal cardboard box mold at the third mold stopping position matches the second supporting part.

[0019] The beneficial effects of this utility model are as follows: This paper box forming and assembly machine (or paper box forming and assembly machine with a front panel) can complete the forming of the paper box body and the connection between the box body and the front panel, resulting in relatively high production efficiency. The entire paper box structure can be formed and assembled using three flat materials (i.e., a base plate, a long strip of front panel, and a front panel, wherein the cardboard portion of the long strip and the front panel is usually pre-grooved for folding or assembly). The transportation and storage costs of the flat materials are relatively low, and they occupy little space, thus reducing production costs. This paper box forming and assembly machine can directly produce the paper box body and connect and assemble it with the front panel, which is more efficient, eliminates the need for additional box body collection and transfer, and reduces the number of production steps.

[0064] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the implementation of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0065] Referring to the accompanying drawings, the paper box forming and assembly machine in this embodiment can complete the forming of the paper box body and the connection between the box body and the panel shell, and can be used to make paper boxes such as book boxes. The paper box forming and assembly machine includes a rotary mold device 5, a bottom plate mold assembly mechanism 1, a box body forming mechanism 2 that forms a frame by a long strip shell upper mold and connects to the bottom plate, a panel shell adhesive box body assembly mechanism 3, and a paper box demolding mechanism 4.

[0066] The rotary mold device 5 includes a horizontal cardboard box mold 50 (which can be simply referred to as a mold). The horizontal cardboard box mold 50 is horizontal, and the cardboard box is formed and assembled on the mold in a horizontal position. The bottom of the cardboard box on the horizontal cardboard box mold 50 will be in a vertical state. In this embodiment, a square cardboard box will be used as an example for illustration. The rotary mold device 5 is equipped with at least a first mold stopping position 11, a second mold stopping position 21, a third mold stopping position 31, and a fourth mold stopping position 41. The first mold stopping position 11, the second mold stopping position 21, the third mold stopping position 31, and the fourth mold stopping position 41 are arranged in a circumferential direction. During the rotation (i.e., revolution) process, the horizontal cardboard box mold 50 can stop sequentially at each mold stopping position (first mold stopping position 11, second mold stopping position 21, third mold stopping position 31, and fourth mold stopping position 41) to cooperate with the cardboard box forming and assembly operation.

[0067] The first mold stopping position 11 is connected to the box bottom plate mold assembly mechanism 1. The box bottom plate mold assembly mechanism 1 is used to assemble the box bottom plate (which can be simply referred to as the bottom plate, which is the bottom of the paper box. In the vertical state, the box opening and the box bottom are vertically aligned. In this embodiment, the paper box is in a horizontal state on the mold, and the box bottom plate will be located on the outer side of the mold relative to the rotation center) onto the horizontal paper box mold 50. When the horizontal paper box mold 50 is at the first mold stopping position 11, it will cooperate with the bottom plate assembly. The bottom plate is installed by the box bottom plate mold assembly mechanism 1 on the corresponding position (outer side 51) of the horizontal paper box mold 50, realizing the bottom plate mold (that is, the bottom plate is put onto the mold).

[0068] Among them, the second mold stopping position is connected to the box forming mechanism 2, which is a long strip of leather upper mold forming a frame and connecting the box bottom plate. The box forming mechanism is used to put the long strip of leather onto the mold (paper box horizontal mold) and the long strip of leather relies on the mold to form a frame and connect with the box bottom plate to form the box body of the paper box, thereby realizing the box forming.

[0069] The third mold stopping position is connected to the panel skin adhesive box assembly mechanism 3, which is used to adhesively attach the panel skin to the box body (which has been formed at the second mold stopping position 21) (located on the outer periphery of the box body), thus completing the paper box assembly. The panel skin can serve as the box lid and outer panel of the box body, folding over and covering the outside of the box body to form a book-shaped paper box structure.

[0070] Among them, the fourth mold stopping position is connected to the paper box demolding mechanism 4. The paper box demolding mechanism 4 cooperates to remove the assembled paper box from the mold. There are many ways to make the paper box demolding mechanism 4, such as using clamping and moving parts that clamp or hook left and right and move back and forth accordingly, or clamping and moving parts that clamp or hook up and move back and forth, or telescopic ejection parts built into the mold, etc., which are also relatively mature and will not be described in detail.

[0071] This cardboard box forming and assembly machine (or cardboard box forming and assembly machine with a front panel) can complete the forming of the cardboard box body and the connection between the box body and the front panel, with relatively high production efficiency.

[0072] The entire cardboard box structure can be formed and assembled using three flat materials (i.e., the base plate, the long strip shell, and the front panel shell, where the cardboard portion of the long strip shell and the front panel shell is usually pre-grooved for folding or assembly). The transportation and storage costs of the flat materials are relatively low, and they do not occupy much space, which reduces production costs.

[0073] This cardboard box forming and assembly machine can directly produce the box body and connect and assemble it with the panel and shell, which is more efficient, eliminates the need for additional box collection and transfer, and reduces the number of production steps.

[0074] For example, after adopting this carton forming and assembly machine, manufacturers can directly use flat materials for carton forming and assembly. Compared to using top and bottom box forming equipment (including corner attaching machines) or other carton forming equipment to pre-make the box bodies and then collecting and transferring them to a (horizontal) conveyor belt to lay flat on the outer shell panel, the carton forming and assembly in this embodiment has fewer production steps, requires no additional box collection and transfer, and has relatively lower production and warehousing costs. Furthermore, it eliminates the need to purchase additional equipment (such as a carton forming machine to make the box bodies), reducing equipment purchase costs and production and box collection and transfer steps. Of course, outer shell production equipment can also be configured to assist in production, and combining them in a network can further improve efficiency.

[0075] Based on the above embodiments, the following optimizations or further explanations can be made.

[0076] For example, the box bottom plate mold assembly mechanism 1 includes an assembly flipping frame 10, which has a first support portion 101. The first support portion 101 is used to cooperate with the flipping assembly of the bottom plate. The bottom plate (which is cardboard and serves as the bottom of the box frame) is placed on the first support portion 101 and then flipped for assembly. The assembly flipping frame 10 has a bottom plate assembly station for flipping forward and a bottom plate feeding station for flipping backward. When the assembly flipping frame 10 flips forward, it is the bottom plate assembly station, used to flip and transport the bottom plate on its first support portion 101 to the mating horizontal cardboard mold 50. The bottom plate assembly station is set corresponding to the first mold stopping position 11. When the assembly flipping frame 10 flips backward, it is the bottom plate feeding station, used to input the bottom plate onto its first support portion 101. The bottom plate is a three-part cardboard, including a middle part and left and right side parts. For example, two parallel grooves are cut on the cardboard (after being cut by a slotting device) to divide the three areas, forming a three-part cardboard bottom plate structure. The bottom plate mold assembly mechanism 1 also has a folding plate device 12, which folds the left and right sides of the bottom plate towards the left and right sides of the mold. The folding plate device 12 is set on the assembly flipping frame 10, which has a more reasonable structure and allows the flipping and folding to work together. Its working principle is as follows: when the assembly flipping frame 10 is flipped to the bottom plate feeding position, the bottom plate is placed on its first bearing part 101. When the assembly flipping frame 10 is flipped to the front position, the bottom plate on the first bearing part 101 can be flipped to the position for assembly. In addition, the folding plate device 12 can also work to fold the left and right sides of the bottom plate towards the left and right sides of the mold. It can work with the corresponding mold to participate in the production of the framed cardboard box. When the frame is assembled later, the long strip of cardboard (i.e., the long strip of shell) can be attached to the left and right sides of the bottom plate to form the box body, ensuring that the long strip is firmly assembled with the bottom plate and the connected structure is stable and not easy to detach. It can be used to assemble the base plate onto the corresponding mold, and the left and right sides of the base plate are folded towards the left and right sides (faces) of the mold to complete the transfer and assembly of the base plate. This makes it easier to connect with the base plate more stably when the frame is assembled later, ensuring that the subsequent long strip shell is firmly assembled with the base plate. The connected structure is stable and not easy to separate or fall apart, and it can cooperate in the production of paper box body forming.

[0077] For example, the box forming mechanism 2, which uses a long strip of leather to form a frame and connect to the box bottom plate, includes a surrounding device 22 for overlapping and surrounding the long strip of leather and a pre-adhesive device 23 for the long strip of leather. The pre-adhesive device 23 applies adhesive to the long strip of leather in advance so that the long strip of leather overlaps and is glued together to form a frame, and the long strip of leather (frame) is glued to the bottom plate. The surrounding device 22 of the long strip of leather overlapping and surrounding mold can surround the long strip of leather, with both ends of the long strip of leather overlapping and surrounding the mold to form a frame, and connecting the long strip of leather (frame) to the bottom plate to complete the box forming.

[0078] For example, the panel and casing adhesive assembly mechanism 3 includes a casing feeding station 32, a casing gluing station 33, and a casing flipping assembly station 34. The casing gluing station 33 is located between the casing feeding station 32 and the casing flipping assembly station 34. The casing feeding station 32, the casing gluing station 33, and the casing flipping assembly station 34 are connected by the casing feeding device 35. That is, the casing feeding device 35 cooperates to transport the panel casing from the casing feeding station 32 to the casing gluing station 33, and then transports the panel casing from the casing gluing station 33 to the casing flipping assembly station 34. The panel cover is supplied at the panel cover feeding station 32; the panel cover is pre-glued at the panel cover gluing station 33 so that it can be glued to the box body on the horizontal cardboard mold 50, and the box body has been pre-formed at the second mold stopping position 21; the panel cover is flipped onto the horizontal cardboard mold 50 (stopped at the third mold stopping position 31) at the panel cover flipping assembly station 34 to complete the assembly of the panel cover with the box body (on the horizontal cardboard mold 50). The panel cover flipping assembly station 34 is set to correspond to the third mold stopping position 31 so that the horizontal cardboard mold 50 can complete the panel cover flipping assembly at the third mold stopping position 31, receive the panel cover, and complete the assembly connection between the panel cover and the box body.

[0079] For example, in this embodiment, a base plate hopper 13 is connected to the rear of the base plate feeding station. A base plate conveying device 14 is connected between the base plate hopper 13 and the base plate feeding station. The base plate conveying device 14 cooperates to convey the base plates in the base plate hopper 13 to the base plate feeding station and then to the first bearing part 101 of the assembly flipping frame 10. The structure and cooperation method of the base plate hopper 13 and the base plate conveying device 14 are numerous and relatively mature. The outer side 51 of the horizontal cardboard box mold 50 at the first mold stopping position 11 mates with the first bearing part 101 when it is flipped forward to the assembly flipping frame 10. The assembly flipping frame 10 flips forward to flip the base plate on the first bearing part 101 to the outer side 51 of the horizontal cardboard box mold 50. Then, the folding plate device 12 can fold the left and right sides of the base plate to the left and right sides of the mold respectively.

[0080] The horizontal cardboard box mold 50 has vertically arranged left, right and outer sides 51, while its upper and lower sides are horizontally arranged to facilitate the assembly and forming of square boxes. This allows the panel and outer shell to be folded and attached to the left and right sides. The left, right and / or outer sides 51 of the horizontal cardboard box mold 50 are equipped with suction plate components 53 (such as air nozzles, air holes, etc.) to help hold the bottom plate in place and prevent it from falling off during mold movement. The inner side of the horizontal cardboard box mold 50 corresponds to the box opening, and the outer side 51 corresponds to the box bottom, forming a horizontal structure. The outer side 51 refers to the side of the horizontal cardboard box mold 50 that is away from the center of rotation (revolution), and the inner side refers to the direction of the horizontal cardboard box mold 50 towards the center of rotation (revolution).

[0081] Further optimization involves connecting the assembly flipping frame 10 to the first flipping shaft 102. The assembly flipping frame 10 will rotate back and forth around the first flipping shaft 102. The axis of the first flipping shaft 102 is horizontally set. The assembly flipping frame 10 is connected to a reciprocating flipping drive device 103 (such as a cylinder or motor). The reciprocating flipping drive device 103 will drive the assembly flipping frame 10 to flip forward (i.e., forward flip) and backward (i.e., backward flip). The reciprocating flipping drive device 103 can be directly connected to the assembly flipping frame 10, or it can be connected to the assembly flipping frame 10 through the first flipping shaft 102, cooperating with the transmission to achieve the flipping. The folding plate device 12 includes push-insertion components 121 respectively disposed on the left and right sides of the assembly flipping frame 10, which can correspondingly fold the left and right sides of the base plate towards the left and right sides of the mold. The push-insertion component 121 is connected to the push-insertion drive component 122 (such as a motor or cylinder), which drives the push-insertion component 121 to move, and the push-insertion component 121 folds the left and right sides of the base plate toward the left and right sides of the mold. The left and right push-insertion components 121 can be equipped with push-insertion drive components 122 separately, or they can share push-insertion drive components 122. For example, the push-insertion component 121 adopts a straight-push reciprocating insert plate, which pushes the insert plate in a straight line to the left and right sides of the base plate, and folds them to the left and right sides of the mold. Its operating space is relatively small, it occupies little space, and its structure is compact and does not easily interfere with other actions. The straight-push reciprocating (back and forth) operation is simple and fast, and the load on the assembly flipping frame 10 is also relatively small. Among them, the push-insertion drive component 122 is arranged on the back of the first bearing part 101. The push-insertion path of the push-insertion component 121 is orthogonal to the bearing plane of the first bearing part 101. The straight-push reciprocating insert plate can move along the left and right sides of the mold respectively, and fold the left and right sides of the base plate to the left and right sides of the mold. The push-insertion drive component 122 is connected to the assembly flipping frame 10. The first support part 101 has a folding plate channel 123 for the push-insertion component 121 to pass through the push-insertion folding plate. After the push-insertion component 121 retracts, the first support part 101 can smoothly accept the base plate. Subsequently, the push-insertion component 121 can extend through the folding plate channel 123 to fold the left and right sides of the base plate on the first support part 101 towards the left and right sides of the mold. The push-insertion component 121 is adjusted to the left and right positions on the assembly flipping frame 10 to ensure smooth operation and adapt to different specifications and sizes of base plates and molds. The front, left, and right sides of the first support part 101 are respectively equipped with limiting stops 105 for limiting the base plate to its position, so that the relative position of the base plate placed on the first support part 101 of the assembly flipping frame 10 is accurate and the base plate is limited when it is input onto the first support part 101. The limiting stops 105 are connected to the assembly flipping frame 10 and are not easily displaced during flipping. The front limit stop 105 is adjusted and set to the front and rear positions on the assembly tilting frame 10, and the left and right limit stop 105s are adjusted and set to the left and right positions on the assembly tilting frame 10.For example, the limit stop 105 is installed on the support plate 108 with fasteners to adjust its position. A long hole can be used for easy position adjustment. Additionally, the horizontal cardboard box mold 50 has mounting plate receiving recesses 52 on both the left and right sides. These recesses allow the left and right sides of the base plate to fold in, ensuring smooth connection with the left and right sides of the base plate during subsequent assembly of the long strip. Furthermore, the mounting plate receiving recesses 52 can be designed as grooves to hold and support the left and right sides of the base plate after folding in, preventing them from falling off.

[0082] For example, the bottom plate hopper 13 includes left and right side plates 131 and a discharge front baffle 132. The bottom of the bottom plate hopper 13 is provided with a material support component 133 to support the stacked bottom plates in the bottom plate hopper 13. The material support component 133, together with the left and right side plates 131 and the discharge front baffle 132, forms a hopper for receiving stacked bottom plates. A single-plate output gap is left between the discharge front baffle 132 and the material support component 133 below so that a single bottom plate can be output. The discharge front baffle 132 can block the output of other bottom plates above. There are many ways to make the bottom plate conveying device 14, such as using a pusher and / or a conveyor belt (or even setting the material support component 133 to cooperate with the conveyor belt to support and output the bottom plate). Single-stroke or multi-stroke conveying methods can be used. For example, the bottom plate conveying device 14 is used to transport the bottom plates one by one from the bottom of the bottom plate silo 13. For instance, the bottom plate conveying device 14 includes a plate ejection pusher 141, which is connected to a plate ejection pushing power component 142 (such as a motor or cylinder). The plate ejection pusher 141 is a mature technology; it can be a lifting type or a type that can retract and lift the upper side of the bottom plate in the bottom plate silo 13. The first bearing part 101 on the assembly turning frame 10 at the bottom plate feeding station cooperates with the material support component 133 for feeding, so that the bottom plate is pushed from the material support component 133 onto the first bearing part 101. The material support component 133 uses a material support plate, which is higher than the first bearing part 101 during feeding. 01 or the material support plate is flush with the first bearing part 101; the material support plate is flat, and the first bearing part 101 is flat; the material support component 133 has a pushing channel 1331 for the movement of the plate pusher head 141, and the plate pushing power component 142 is located below the material support component 133; the discharge front baffle 132 is connected to the left and right side plates 131, and the discharge front baffle 132 is located at the front of the left and right side plates 131; the height position of the discharge front baffle 132 on the left and right side plates 131 is adjustable to adjust the size of the single plate output gap to ensure that a base plate is output smoothly; the left and right positions of the left and right side plates 131 are adjustable to adapt to base plates of different specifications; the base plate hopper 13 is also equipped with a tail baffle component 134, so that the position of the base plate in the hopper is relatively more stable and accurate.

[0083] The horizontal cardboard box mold 50 revolves around a vertically positioned main shaft 54, with the main shaft 54 ​​as its center of rotation. The horizontal cardboard box mold 50 is connected to the main shaft 54 ​​and is distributed circumferentially along the main shaft 54. The horizontal cardboard box mold 50 pauses intermittently at various mold stopping positions during its revolution. For example, the horizontal cardboard box mold 50 revolves around the vertically positioned main shaft 54 ​​to facilitate its movement and stopping at different workstations to achieve cardboard box forming and assembly. For instance, connecting the horizontal cardboard box mold 50 to the main shaft 54 ​​allows the main shaft 54 ​​to drive the horizontal cardboard box mold 50 to rotate. The horizontal cardboard box mold 50 is distributed circumferentially along the main shaft 54, which can adapt to multi-station production needs and is highly efficient, such as the four mold stopping positions shown in the figure (i.e., four stopping stations). The main shaft 54 ​​can be driven to rotate by an indexing box or similar device.

[0084] For example, in this embodiment, the box forming mechanism 2, which connects the box bottom plate to the frame formed by the upper mold of the long strip shell, also includes a long strip shell feeding device 24. Additionally, the long strip shell pre-adhesive device 23 includes a pre-adhesive component 231 (such as a glue gun), which is positioned above the conveying path of the shell conveying component 25. The shell conveying component 25 connects to the long strip shell feeding device 24, and the shell conveying component 25 connects to the enclosure device 22 of the long strip shell overlapping and enclosing mold. The long strip shell pre-adhesive device 23 is positioned between the long strip shell feeding device 24 and the enclosure device 22; the long strip shell pre-adhesive device 23 is used to convey the long strip shell. As the outer shell moves, the outer shell conveying component 25 cooperates to convey the long outer shell supplied by the long outer shell feeding device 24. During the conveying process, it passes below the pre-gluing component 231, where the pre-gluing component 231 applies glue to the long outer shell on the conveying path. After the glue is applied, the long outer shell is conveyed by the outer shell conveying component 25. When applying glue, the outer shell conveying component 25 can stop and wait for the glue to be completed before continuing to convey (the glue application is relatively more stable), or it can not stop.

[0085] For example, the long strip box body feeding device 24, the long strip box body pre-gluing device 23, and the enclosure device 22 are arranged sequentially in a straight line, and the box body conveying component 25 can convey the long strip box body in a straight line. The box body conveying component 25 can be a conveyor belt or a conveyor pusher, and can be equipped with a corresponding motor or cylinder for drive. In addition, the enclosure device 22 is a mature existing technology. The enclosure device 22 includes a clamping upper mold mechanism 221, which includes a base 2212. The base 2212 is provided with a support plate 2213 and left and right side flip plates 2214. The left and right side flip plates 2214 are arranged on the left and right sides of the support plate 2213. The second mold stopping position 21 is correspondingly matched with the support plate 2213 below. The support plate 2213 and the horizontal cardboard box mold 50 above move closer to each other. The left and right side flip plates 2214 flip from the left and right sides to the horizontal cardboard box mold 50 in the middle position above, clamping the upper mold. Mechanism 221 can upwardly embrace the horizontal cardboard box mold 50, which is positioned at the second mold stopping position 21. This can be achieved using a lifting-type horizontal cardboard box mold 50 (as shown in the figure) and / or a lifting-type pallet 2213. Additionally, the enclosure device 22 includes a box body side forming mechanism 222, which is positioned above the second mold stopping position 21. This mechanism assists in completing the overlapping enclosure operation, ensuring the adhesive joints of the overlapping enclosure are connected, forming a frame with the long cardboard box overlapping end-to-end. The pallet 2213 can be equipped with a suction nozzle (capable of holding material) to stably support the long cardboard box above, preventing displacement during operation.

[0086] The upper mold clamping mechanism 221 is connected to the shell conveying component 25. The shell conveying component 25 works to convey the glued strip shell to the upper mold clamping mechanism 221. The strip shell can be directly conveyed to the upper mold clamping mechanism 221 or conveyed with the assistance of the shell transfer robot 26 (which can improve the conveying efficiency). As shown in the figure, the shell conveying component 25 and the enclosure device 22 are also connected to the shell transfer robot 26. The shell transfer robot 26 is connected between the upper mold clamping mechanism 221 and the shell conveying component 25. The shell transfer robot 26 (such as including a lifting suction nozzle, driven by a multi-axis industrial robot arm or lifting and translational movable frame) works to transfer the strip shell conveyed by the shell conveying component 25 to the upper mold clamping mechanism 221 (such as its support plate 2213 and left and right side flip plates 2214), improving the connection conveying efficiency and stability. The base 2212 of the upper mold clamping mechanism 221 is located below the second mold stopping position 21. Furthermore, during the molding and assembly process, the base 2212 can be fixed; alternatively, a reciprocatingly moving base 2212 can be used, with the corresponding support plate 2213 and left and right side flaps 2214 moving inward and outward together with the base 2212. Corresponding guide rails 22121 can be configured for guidance and power drive. The base 2212 has a receiving position on the outer side and a clamping upper mold position on the inner side, and the base 2212 can switch between the receiving position and the clamping upper mold position. The base 2212 connects with the housing transfer robot 26 at the receiving position. The robotic arm 26 transfers the long strip of leather to the tray 2213 and left and right side flaps 2214 of the base 2212. Then, the base 2212 moves inward to the position where it engages with the upper mold. At this position, the base 2212 connects with the second mold stopping position 21. The tray 2213 and left and right side flaps 2214 on the base 2212 then cooperate with the horizontal cardboard box mold 50 at the second mold stopping position 21 to connect and engage the long strip of leather onto the horizontal cardboard box mold 50. This combination results in relatively fast operation. The horizontal cardboard box mold 50 at the second mold stopping position 21 is correspondingly and properly positioned with the tray 2213 below it.

[0087] The box body side forming mechanism 222 is a mature existing technology. For example, the box body side forming mechanism 222 includes an upper side plate folding and pressing component 2221 and an end-to-end overlapping and pasting paper component 2222. The upper side plate folding and pressing component 2221 (which can be driven by a motor or cylinder to run on the inclined track 2225 for inclined pressing) folds and presses a section of the edge of the long strip shell (which is already wrapped on the horizontal paper box mold 50 on the lower and left and right sides) toward the upper side of the horizontal paper box mold 50, so that the long strip shell finally forms a frame. Then, the end-to-end overlapping and pasting paper component 2222 overlaps and pastes the paper at the ends of the long strip shell onto the outside of the long strip shell that forms the frame, so that the ends of the long strip shell that forms the frame are glued together. The upper side plate folding and pressing component 2221 can be a folding and pressing plate or a roller, and the end-to-end overlapping and pasting paper component 2222 can be a roller, etc.

[0088] This embodiment can be further optimized. The end-to-end overlapping mounting paper component 2222 is connected to the lateral shifting drive device 2223 (which may include a cylinder or a motor as power). The end-to-end overlapping mounting paper component 2222 is also connected to the lifting mounting drive device 2224 (which may include a cylinder or a motor as power). That is, the end-to-end overlapping mounting paper component 2222 can be laterally shifted and lifted for mounting, so that it (end-to-end overlapping mounting paper component 2222) is laterally shifted into position for lowering the mounting paper and overlapping the paper. The adhesive is applied to the outside of the long strip of outer shell that forms the frame. Its horizontal movement and retraction, as well as its upward return, avoid the position so that the left / right flip plates 2214 (on the base 2212 of the upper mold mechanism 221) can smoothly flip the long strip of outer shell to the left / right side of the horizontal cardboard box mold 50. In this optimized structure, the overlapping adhesive position of the beginning and end can be set on the left or right side of the horizontal cardboard box mold 50. It can then be covered by the folded material of the panel outer shell, which is not only more secure, but also covers the overlapping adhesive position of the beginning and end, making the cardboard box more beautiful.

[0089] In addition, the pre-adhesive component 231 includes an adhesive component 2311 for the overlapping joint of the face paper of the long strip of the shell and an adhesive component 2312 for the joint of the long strip of the shell connected to the outside of the folded plate portions on the left and right sides of the base plate. The adhesive component 2311 for the overlapping joint of the face paper of the long strip of the shell is the first adhesive component, which is used to apply adhesive to the overlapping joint of the face paper of the long strip of the shell. The overlapping joint of the face paper of the long strip of the shell is located at the left or right end of the face paper portion, which is used to glue the ends of the long strip of the shell together. The second gluing component is used to apply glue to the areas of the long strip of the outer casing that correspond to the folded sections on the left and right sides of the base plate of the horizontal cardboard box mold 50. This allows the corresponding areas of the long strip of the outer casing to adhere to the folded sections on the left and right sides of the base plate (already folded towards the left and right sides of the mold) after gluing. The first and second gluing components can be applied using a glue gun, either in a horizontal or vertical (same as the conveying direction of the outer casing conveying component 25) manner, or arranged in a horizontal or vertical configuration. Depending on the requirements, gluing can be applied horizontally or vertically to the long strip of the outer casing.

[0090] For example, in this embodiment, the shell feeding station 32, the shell gluing station 33, and the shell flipping and assembly station 34 are arranged in a straight line.

[0091] The casing feeding device 35 includes a forward feeding component 351, which sequentially feeds casings from the casing feeding station 32 to the casing gluing station 33 and the casing flipping assembly station 34. Specifically, the forward feeding component 351 assists in feeding the panel casing from the casing feeding station 32 to the casing gluing station 33, where the panel casing is glued. Then, the forward feeding component 351 feeds the glued panel casing from the casing gluing station 33 to the casing flipping assembly station 34, where the panel casing is flipped and assembled. For example, the forward feeding component 351 can use a feeding belt and / or a feeding pusher, such as a feeding pusher that pushes forward and backward in a step-by-step manner. Other types of forward feeding components 351 can also be used. The left and right sides of the forward feeding component 351 are also equipped with left and right side stops 352 for limiting the feeding of the panel shell. The left and right side stops 352 work together to limit the left and right sides of the panel shell so that the panel shell is relatively accurate in position during the feeding process and is not easy to shift to the left or right.

[0092] In addition, the casing gluing station 33 is equipped with a casing upper side gluing device 331, which is used to apply glue to the upper side of the panel casing at this station. For example, the casing upper side gluing device 331 includes a horizontal gluing component and / or a vertical gluing component, such as using a glue gun as the gluing component, to apply horizontal and / or vertical gluing to the upper side of the panel casing. For horizontal gluing, the horizontal gluing component can be arranged horizontally or laterally, and for vertical gluing, the vertical gluing component can be arranged vertically or longitudinally, or the vertical gluing component can be moved relative to the feeding direction of the casing feeding device 35 to apply vertical gluing. The casing upper side gluing device 331 is positioned above the feeding path of the casing feeding device 35, for example, above the forward feeding component 351, so as to apply glue to the panel casing below.

[0093] For example, the casing flipping and assembly station 34 is equipped with a casing flipping and assembly device 341, which cooperates to receive and flip the panel casing for assembly. For example, the casing flipping and assembly device 341 includes a flipping assembly frame 342, which has a second support part 3421. The second support part 3421 is used to cooperate in supporting the flipping and assembly of the panel casing. After the panel casing is placed on the second support part 3421, it is flipped and assembled. In addition, the flip assembly frame 342 is connected to the second flip shaft 343. The flip assembly frame 342 will flip back and forth around the second flip shaft 343. The axis of the second flip shaft 343 is set horizontally. The flip assembly frame 342 is connected to the forward and backward flip drive device 344 (such as including a motor or cylinder). The forward and backward flip drive device 344 will drive the flip assembly frame 342 to flip forward (i.e., forward flip) and flip backward (i.e., backward flip). The forward and backward flip drive device 344 can be directly connected to the flip assembly frame 342, or it can be connected to the flip assembly frame 342 through the second flip shaft 343 to achieve flipping in conjunction with the transmission.

[0094] The flip assembly frame 342 has a forward-flipped assembly position and a backward-flipped input position for the outer casing. When the flip assembly frame 342 flips forward, it is in the outer casing assembly position, meaning that the panel casing on its second support part 3421 is flipped and transported to the mating horizontal cardboard box mold 50 (on which the cardboard box body has already been formed). When the flip assembly frame 342 flips backward, it is in the outer casing input position, used for inputting the panel casing onto its second support part 3421. The second support part 3421 of the flip assembly frame 342 is correspondingly arranged to the outer side 51 of the horizontal cardboard box mold 50, which is located at the third mold stopping position 31. This second support part 3421 can be flipped to the outer side 51 of the horizontal cardboard box mold 50, allowing it to be assembled and connected with the cardboard box body (bottom) on the horizontal cardboard box mold 50, resulting in a better assembly effect.

[0095] For example, the shell feeding station 32 can be equipped with a shell stacking feeding bin 321, which can stack the manufactured panel shells and place them in the shell stacking feeding bin 321 for output feeding one sheet at a time. The shell feeding device 35 (such as including a forward feeding component 351) cooperates to transport the panel shells supplied by the shell stacking feeding bin 321 forward to the shell gluing station 33 and the shell flipping assembly station 34.

[0096] There are many ways to supply long strips of packaging shells. For example, the long strip packaging shell feeding device 24 may also include a packaging shell stacking feeding bin 321, which can stack the produced long strips of packaging shells in the packaging shell stacking feeding bin 321 for output feeding one by one.

[0097] The feeding method of the shell stacking feeding bin 321 is combined with various structures. For example, the bottom of the shell stacking feeding bin 321 has a discharge port, which is equipped with a lifting and lowering feeding nozzle 322. The lifting and lowering feeding nozzle 322 is set to correspond to the discharge port and is set to face upward. The lifting and lowering feeding nozzle 322 (which can be equipped with a motor or cylinder to drive the lifting) can lift up and suck up the bottom shell (such as a long panel or long shell) stacked in the shell stacking feeding bin 321, and then lower down to move the shell downward, which can transfer and feed the shell one by one. In addition, the bottom of the shell stacking feeding bin 321 is equipped with front and rear horizontal support bars 323. The discharge port is located between the front and rear horizontal support bars 323. The front and rear horizontal support bars 323 cooperate to support the front and rear edges (i.e., the front and rear edges of the shells) stacked in the shell stacking feeding bin 321. The horizontal support bars 323 can be round bars (either complete round bars or incomplete round bars with facets), which is convenient for processing and facilitates the suction and downward transfer of the stacked shells after supporting the front and rear edges. When the bottom layer of shell is suctioned and pulled down, it will slightly deform so that its front and rear edges separate from the corresponding horizontal support bars 323, thus smoothly passing through the discharge port and being discharged downwards. The shell stacking bin has a storage space for stacking shell materials with front and rear oriented grooves.

[0098] In addition, a material support rail 37 is configured below the discharge port. The material support rail 37 is laid from back to front. The shell conveying component 25 or the forward feeding component 351 is configured on the side of the material support rail 37. The lifting and lowering feeding nozzle 322 is connected between the shell stacking feeding bin 321 and the material support rail 37. The shell at the bottom of the shell stacking feeding bin 321 can be sucked up by the (lifting and lowering feeding nozzle 322) and moved down to be placed on the material support rail 37 to be supported, so as to cooperate with the shell conveying component 25 or the forward feeding component 351 to transport the shell forward from back to front. For example, the material support rail 37 adopts a material support straight rail.

[0099] For example, the material support rail 37 is laid from the outer shell feeding station 32, through the outer shell gluing station 33, to the outer shell flipping and assembly station 34; another example is that another set of material support rails 37 is laid forward from the long strip outer shell feeding device 24, through the long strip outer shell pre-gluing device 23, and continues forward to connect with the enclosure device 22. A positioning and limiting structure can also be set at the end of the material support rail 37 to limit the outer shell when it moves forward into position.

[0100] The feeding method of the above-mentioned shell stacking feeding bin 321 is suitable for feeding shell materials. The shell materials stacked in it are less likely to rub against each other and scratch the face paper. The bottom layer of shell materials can be separated one by one and taken down for output. In addition, materials with groove structures (front and back direction) on the shell can also be fed and output smoothly. The shell materials can be stacked smoothly in it (shell stacking bin) and picked up one by one and transferred downward. They can also be smoothly moved forward along the material support rail 37 (consistent with the direction of the groove structure on the shell material). It is not easy for the shell material to bend due to the grooves, affecting stacking, discharge (i.e., unloading) and forward feeding.

[0101] Furthermore, the outer shell feeding station 32 or the box body long strip outer shell feeding device 24 (or their outer shell stacking feeding bins 321) can be connected to the outer shell production equipment (a mature technology) to form an online system, which can also improve production efficiency. The outer shells (such as long strip panels or long strip outer shells) produced by the outer shell production equipment are directly fed to the outer shell feeding station 32 or the box body long strip outer shell feeding device 24.

[0102] In addition, the second support part 3421 is provided with rollers 345 for folding and rolling materials on its left and / or right sides. The rollers 345 are used for folding and rolling materials. The left and / or right rollers 345 are respectively positioned on the left and / or right sides of the horizontal cardboard box mold 50 at the third mold stopping position 31. The rollers 345 are connected to the linear reciprocating transmission component 346. The linear reciprocating transmission component 346 drives the rollers 345 to move back and forth on the left and / or right sides of the horizontal cardboard box mold 50. After the panel shell is flipped and assembled onto the outer side 51 of the horizontal cardboard box mold 50 (at this time, the second support part 3421 can cooperate to move the panel shell onto the outer side 51 of the horizontal cardboard box mold 50), the rollers 345 are used for folding and rolling materials. The corresponding part of the panel shell is pressed against the outer side 51 of the horizontal paper box mold 50. At this time, the horizontal paper box mold 50 already has a paper box body. The roller 345 can also fold the panel shell (except for the part corresponding to the outer side 51 of the horizontal paper box mold 50) to the left and / or right side of the horizontal paper box mold 50. While folding it to the left and / or right side of the horizontal paper box mold 50 (it can be glued to the left and / or right side of the paper box body on the horizontal paper box mold 50), it can also roll the panel shell to ensure that the panel shell is firmly and flatly glued to the left and / or right side of the left and / or right side of the body on the horizontal paper box mold 50. This structure not only allows the bottom of the cardboard box to be connected to the outer shell, but also allows the side wall of the cardboard box (corresponding to the horizontal cardboard box mold on the left and right sides) to be connected to the outer shell, meeting more needs. It can even make the cardboard box more robust. After the outer shell is folded, it can be wrapped around the outside of the long strip of outer shell paper overlap and glued. The overlap and glued positions at the beginning and end are covered and concealed, making the cardboard box more beautiful.

[0103] The roller 345 can be made of materials such as rubber rollers or brush rollers. Furthermore, the roller 345 and the linear reciprocating transmission component 346 (such as including a cylinder or motor) are connected to the flipping assembly frame 342, allowing it to flip and move together with the frame. The structure is reasonable, compact, and easy to operate. The linear reciprocating component is located on the back of the second support section 3421, minimizing interference with the material receiving and flipping assembly of the second support section 3421.

[0104] The outer side 51 of the horizontal cardboard box mold 50 at the third mold stopping position 31 mates with the second support part 3421 when it is flipped into position towards the flip assembly frame 342. The horizontal cardboard box mold 50 at the third mold stopping position 31 corresponds to the shell flip assembly device 341, and the cardboard box body on the horizontal cardboard box mold 50 can be assembled with the panel shell in the shell flip assembly device 341. The outer side 51 of the horizontal cardboard box mold 50 at the third mold stopping position 31 matches the second support part 3421 so that the second support part 3421 can more stably press the corresponding part of the panel shell onto the outer side 51 of the horizontal cardboard box mold 50, ensuring smoother and more stable folding of the subsequent roller 345, and neater crease positions. For example, a roller 345 for attaching the cardboard box to the folding and rolling casing is mounted on a roller support 347. The roller support 347 is connected to a linear reciprocating transmission component 346, meaning the roller 345 is connected to the linear reciprocating transmission component 346 via the roller support 347. A linear track can also be configured to ensure stable linear movement. For instance, a flip assembly frame 342 includes left and right flip rods 3422. Each flip rod 3422 is loosened (by fasteners) and secured on a second flip shaft 343. This allows the position of the flip rods 3422 on the second flip shaft 343 to be adjusted after loosening, adapting the spacing between the flip rods 3422 to accommodate different cardboard box sizes. After adjustment, the rods are locked to maintain their position on the second flip shaft 343. A second bearing portion 3421 is located on the flip rod 3422, and a roller is located outside the flip rod 3422, meaning the left roller is located on the left flip rod 3422. On the left and right sides of 22, the rollers are located on the right side of the right flipping rod 3422. The rollers and the linear reciprocating transmission component 346 are connected to the flipping rod 3422 so that they can be adjusted left and right together with the flipping rod 3422 on the second flipping shaft 343. The structure is compact and easy to use. At the second bearing part 3421, there is also a suction part (such as an air intake hole or air nozzle for air supply) for sucking up the shell. The suction part can cooperate to suck up the panel shell when the flipping assembly frame 342 flips up the panel shell to prevent it from shifting and falling off, ensuring stable operation and relatively accurate assembly. The suction part can be set on the flipping rod 3422. The flip assembly frame 342 is also equipped with a limiting front stop 3423 for feeding the panel shell into place, so that when the panel shell is transported to the flip assembly frame 342 (such as the flip rod 3422), it is more accurately positioned and the operation stability is improved. For example, the limiting front stop 3423 is set on the flip rod 3422. When the flip rod 3422 adjusts its relative position, the limiting front stop 3423 also completes the position adjustment at the same time, which is more convenient. The limiting front stop 3423 can also support the leading edge of the panel shell during the flipping process to prevent the panel shell from shifting and falling off during the flipping process.
