Description

Technical Field

[0001] The invention relates to a paper box forming and assembling machine. Background Art

[0002] Paper boxes are often used for packaging, such as wine boxes, gift boxes, etc. Among them, book-shaped boxes are one of the main types of paper box structures. The structure of this type of paper box (such as a book-shaped box) has a panel skin part and a box body part.

[0003] When making and assembling this type of structural paper box, it is necessary to assemble and connect the box body part with the panel skin shell part. During assembly, the panel skin shell can be placed flat on the (horizontal) conveyor belt for transportation, and then the embryo box (box body) can be placed on the panel skin shell of the conveyor belt. This assembly method is relatively simple and lacks diversity. In addition, in this assembly method, only the bottom of the embryo box (box body part) and the skin shell (upper surface) can be fitted and connected. Moreover, this method of directly assembling the box body part with the skin shell part requires the preparation of box bodies, or the configuration of paper box body forming equipment to produce box bodies. For manufacturers, the preparation of box bodies will occupy the procurement, transportation and warehousing costs, and the cost is relatively high, and it occupies a large space; after the box body is produced by the paper box forming machine, it is also necessary to collect, transfer and store the box body. Moreover, the entire paper box production requires the use of paper box body forming equipment, skin shell machine, assembly machine, etc.

[0042] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the implementation mode of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0043] Referring to the accompanying drawings, the paper box forming and assembling machine in the embodiment of the present embodiment can complete the forming of the paper box body and the connection between the box body and the panel skin, and can be used to make paper boxes such as book boxes. The paper box forming and assembling machine includes a rotary mold device 5, a box bottom plate upper mold assembly mechanism 1, a box body forming mechanism 2 in which the long skin upper mold is surrounded by a frame and connected to the box bottom, a panel skin gluing box body assembly mechanism 3, and a paper box demoulding mechanism 4.

[0044] The rotary mold device 5 includes a horizontal carton mold 50 (referred to as a mold), the horizontal carton mold 50 is horizontal, the carton is formed and assembled on the mold in a horizontal manner, and the bottom of the carton on the horizontal carton mold 50 will be in a vertical state. In this embodiment, a square carton will be used as an example for illustration. The rotary mold device 5 is at least equipped with a first mold stop position 11, a second mold stop position 21, a third mold stop position 31 and a fourth mold stop position 41. The first mold stop position 11, the second mold stop position 21, the third mold stop position 31 and the fourth mold stop position 41 are arranged in a circumferential direction. The horizontal carton mold 50 can stop in each mold stop position (the first mold stop position 11, the second mold stop position 21, the third mold stop position 31 and the fourth mold stop position 41) in sequence during the rotation (i.e., revolution) process to cooperate with the carton forming and assembly operation.

[0045] Among them, the first mold stop position 11 is connected to the box bottom plate upper mold assembly mechanism 1, and the box bottom plate upper 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 carton. In the vertical state, the box mouth and the box bottom correspond to each other up and down. In this embodiment, the carton is in a horizontal state on the mold, and the box bottom plate will be on the outer side of the mold relative to the rotation center facing outward) to the horizontal carton mold 50. When the horizontal carton mold 50 is at the first mold stop position 11, it will be assembled with the bottom plate. The bottom plate is installed by the box bottom plate upper mold assembly mechanism 1 at the corresponding position (outer side 51) of the horizontal carton mold 50 to realize the bottom plate molding (that is, the bottom plate is placed on the mold).

[0046] Among them, the second mold stop position is connected to a box body forming mechanism 2 in which a long leather shell upper mold is enclosed in a frame and connected to a box bottom plate. The box body forming mechanism is used to put the long leather shell onto the mold (horizontal paper box mold) and the long leather shell relies on the mold to enclose a frame and connect with the box bottom plate to form a box body of the paper box, thereby realizing box body molding.

[0047] The third mold stop position is connected with a panel skin glue box body assembly mechanism 3, which is used to glue the panel skin to the box body (located outside the box body) (which has been formed at the second mold stop position 21) to complete the paper box assembly. The panel skin can be used as the box cover and the outer panel of the box body, which can be folded and wrapped outside the box body to form a book-shaped box paper box structure.

[0048] Among them, a paper box demoulding mechanism 4 is connected to the fourth mold stop position, and the paper box demoulding mechanism 4 cooperates to separate the assembled paper box from the mold. There are many types of paper box demoulding mechanisms 4, such as a clamping and moving component that clamps or hooks left and right and moves forward and backward accordingly, or a clamping and moving component that clamps or hooks up and down and moves forward and backward, or a telescopic ejection component built into the mold, etc., which are also relatively mature and will not be described in detail.

[0049] The paper box forming and assembling machine (or paper box forming and assembling machine with skin shell panel) can complete the box body forming of the paper box and the connection between the box body and the panel skin shell, and has relatively high production efficiency.

[0050] The entire paper box structure can be formed and assembled using three flat materials (i.e., the bottom plate, the long skin strip, and the panel skin strip, in which the cardboard parts of the long skin strip and the panel skin strip are usually pre-grooved for folding or assembly). The transportation and storage costs of the flat materials are relatively low, and they take up little space, which reduces production costs.

[0051] The paper box forming and assembly machine can directly make the box body of the paper box and connect and assemble it with the panel skin, which is more efficient, does not require additional box body collection and transfer, and has relatively fewer production processes.

[0052] For example, after the manufacturer adopts the carton forming and assembly machine, the flat material can be directly used for carton forming and assembly. Compared with using the top and bottom cover carton forming equipment (including the corner pasting machine) or other carton forming equipment to pre-make the box body, and then collect and transfer the box body to place it on the (horizontal) conveyor belt and lay flat on the skin panel, the carton forming and assembly in this embodiment has fewer production processes, no additional box body collection and transfer is required, the production cost is relatively lower, and the storage cost is relatively low; even, there is no need to purchase other equipment (such as carton forming machines to make box bodies, etc.), reducing the equipment purchase cost and reducing the production links and box body collection and transfer links. Of course, the skin production equipment can also be configured to cooperate with the production, and combined with its online connection, it can also improve efficiency.

[0053] The following optimization or further explanation may be performed based on the above embodiments.

[0054] For example, the box bottom mold assembly mechanism 1 includes an assembly flip frame 10, and the assembly flip frame 10 has a first bearing portion 101. The first bearing portion 101 is used to cooperate with the bearing bottom plate to flip and assemble, and the bottom plate (which is a cardboard, as the bottom of the box body of the frame) is placed on the first bearing portion 101 and flipped and assembled. The assembly flip frame 10 has a bottom plate assembly station that flips forward to the position and a bottom plate feeding station that flips backward to the position. When the assembly flip frame 10 flips forward to the position, it is a bottom plate assembly station, which is used to flip and transport the bottom plate on its first bearing portion 101 to the position to be assembled on the matching horizontal paper box mold 50, and the bottom plate assembly station is set corresponding to the first mold stop position 11. When the assembly flip frame 10 flips backward to the position, it is a bottom plate feeding station, which is used to input the bottom plate onto its first bearing portion 101. Among them, the bottom plate is a three-piece cardboard, including a middle part and left and right side parts, such as two parallel grooves on the cardboard (opened by a slotting device) to divide three area parts to form a bottom plate of a three-piece cardboard structure. The box bottom plate upper mold assembly mechanism 1 also has a folding plate device 12, which folds the left and right sides of the bottom plate to the left and right sides of the mold. The folding plate device 12 will be set on the assembly flip frame 10, and the structure is relatively more reasonable, and the flipping and folding plates can cooperate to operate. Its working principle is that when the assembly flip frame 10 is flipped into place, it is in the bottom plate feeding station, and the bottom plate is placed on its first bearing part 101. The assembly flip frame 10 is flipped into place to flip the bottom plate on the first bearing part 101 into place for assembly, and the folding plate device 12 can also perform additional actions to cooperate to fold the left and right sides of the bottom plate to the left and right sides of the mold; it can cooperate with the corresponding mold to cooperate in the production of the surrounding frame paper box. When the subsequent surrounding frame is enclosed and assembled, the long strip of paperboard (i.e., the long strip of leather shell) is enclosed outside the mold and can be pasted and assembled with the left and right sides of the bottom plate to form a box body, ensuring that the subsequent long strips and the bottom plate are firmly assembled, and the connected structure is stable and not easy to separate. It can cooperate to assemble the bottom plate to the corresponding mold, and the left and right sides of the bottom plate are folded to the left and right sides (surfaces) of the mold to complete the transfer assembly of the bottom plate, so that it is convenient for the subsequent surrounding frame to be stably connected to the bottom plate during assembly, ensuring that the subsequent long leather shell and the bottom plate are firmly assembled, and the connected structure is stable and not easy to separate or fall apart, and cooperates in the production and manufacturing of the paper box body.

[0055] For example, the box body forming mechanism 2 in which the upper mold of the long skin shell is enclosed to form a frame and connected to the bottom plate of the box includes an enclosing device 22 of the long skin shell overlapping and enclosing mold and a long skin shell pre-gluing device 23; the long skin shell pre-gluing device 23 pre-glues the long skin shell so that the long skin shell is overlapped and glued to form a frame, and the long skin shell (frame) is glued to the bottom plate. The enclosing device 22 of the long skin shell overlapping and enclosing mold can enclose the long skin shell, and the two ends of the long skin shell will overlap and enclose on the mold to form a frame, and the long skin shell (frame) is connected to the bottom plate to complete the box body forming.

[0056] For example, the panel shell gluing box body assembly mechanism 3 includes a shell feeding station 32, a shell gluing station 33 and a shell flipping assembly station 34. The shell gluing station 33 is arranged between the shell feeding station 32 and the shell flipping assembly station 34. The shell feeding station 32, the shell gluing station 33 and the shell flipping assembly station 34 are connected by a shell feeding device 35, that is, the shell feeding device 35 cooperates to transport the panel shell from the shell feeding station 32 to the shell gluing station 33, and transports the panel shell from the shell gluing station 33 to the shell flipping assembly station 34. The panel skin is supplied at the skin feeding station 32; the panel skin is pre-glued at the skin gluing station 33 so that it can be subsequently glued to the carton body on the horizontal carton mold 50, and the carton body has been pre-formed at the second mold stop position 21; the panel skin is flipped onto the horizontal carton mold 50 (stayed at the third mold stop position 31) at the skin flip assembly station 34, and the assembly of the panel skin and the carton body (on the horizontal carton mold 50) is completed. The skin flip assembly station 34 is set corresponding to the third mold stop position 31, so that the horizontal carton mold 50 cooperates to complete the skin flip assembly at the third mold stop position 31, receives the panel skin, and cooperates to realize the assembly connection between the panel skin and the carton body.

[0057] For example, in this embodiment, a bottom plate material warehouse 13 is connected to the rear of the bottom plate feeding station, and a bottom plate conveying device 14 is connected between the bottom plate material warehouse 13 and the bottom plate feeding station. The bottom plate conveying device 14 cooperates to convey the bottom plates in the bottom plate material warehouse 13 to the bottom plate feeding station and to the first bearing part 101 of the assembly turning frame 10. The structures and matching methods of the bottom plate material warehouse 13 and the bottom plate conveying device 14 are relatively large and mature. The outer side surface 51 of the horizontal carton mold 50 at the first mold stop position 11 cooperates to dock with the first bearing part 101 when the assembly turning frame 10 is turned forward to the position. The assembly turning frame 10 cooperates to turn forward to be able to turn the bottom plate on its first bearing part 101 to the outer side surface 51 of the horizontal carton mold 50, and then the folding device 12 can fold the left and right sides of the bottom plate to the left and right sides of the mold.

[0058] Among them, the left and right sides and the outer side surface 51 of the horizontal paper box mold 50 are all arranged vertically, and the upper and lower sides of the horizontal paper box mold 50 are arranged horizontally, which is convenient for the assembly and molding of the square box so that the panel skin can be folded and attached to the left and right sides. The left and right sides and / or the outer side surface 51 of the horizontal paper box mold 50 are provided with an air suction and plate suction component 53 (such as an air nozzle, air hole, etc.) which can cooperate to suck the bottom plate to prevent it from falling during the movement of the mold; the inner side of the horizontal paper box mold 50 corresponds to the box mouth, and the outer side surface 51 of the horizontal paper box mold 50 corresponds to the box bottom, which is a horizontal structure. The outer side surface 51 refers to the side of the horizontal paper box mold 50 away from the rotation (revolution) center, and the inner side refers to the direction of the horizontal paper box mold 50 toward the rotation (revolution) center.

[0059] Further optimization, the assembly flip frame 10 is connected to the first flip shaft 102, and the assembly flip frame 10 will flip back and forth around the first flip shaft 102, wherein the axis of the first flip shaft 102 is arranged horizontally, and the assembly flip frame 10 is connected to the front and rear reciprocating flip driving device 103 (such as a cylinder or a motor, etc.), and the front and rear reciprocating flip driving device 103 will drive the assembly flip frame 10 to flip forward (i.e., flip forward) and flip backward (i.e., flip backward). The front and rear reciprocating flip driving device 103 can be directly connected to the assembly flip frame 10, or connected to the assembly flip frame 10 through the first flip shaft 102, and the flipping is realized by transmission. The folding device 12 includes a push-insertion component 121 disposed on the left and right sides of the assembly flip frame 10, which can fold the left and right sides of the bottom plate to the left and right sides of the mold.

The left and right pushing and inserting components 121 can be equipped with a pushing and inserting driving component 122 separately, or they can share the pushing and inserting driving component 122. For example, the pushing and inserting component 121 adopts a straight-push reciprocating plug plate, which pushes and inserts the left and right side parts of the bottom plate in a straight line, and cooperates to fold them to the left and right sides of the mold. Its operation space is relatively narrow, and it occupies a small space. The structure is compact and not easy to interfere with other actions. The straight-push reciprocating (back and forth action) operation is simple and fast, and the load of the assembled turning frame 10 is relatively small; wherein, the pushing and inserting driving component 122 is arranged on the back side of the first bearing part 101, and the pushing and inserting path of the pushing and inserting component 121 is orthogonal to the bearing plane of the first bearing part 101. The straight-push reciprocating plug plate can move along the left and right sides of the mold respectively, and cooperate to fold the left and right side parts of the bottom plate to the left and right sides of the mold. The push-insertion driving component 122 is connected to the assembly flip frame 10, and a folding plate channel 123 is reserved on the first bearing part 101 for the push-insertion component 121 to pass through the push-insertion folding plate. After the push-insertion component 121 retreats, the first bearing part 101 can smoothly provide the bottom plate for input and placement. Subsequently, the push-insertion component 121 can extend through the folding plate channel 123 to fold the left and right sides of the bottom plate on the first bearing part 101 to the left and right sides of the mold. The push-insertion component 121 is relatively adjusted on the left and right positions on the assembly flip frame 10 to ensure smooth operation during debugging, and can also be adjusted to meet the needs of bottom plates and molds of different specifications and sizes. The front side, left side and right side of the first bearing part 101 are respectively provided with a limit stopper 105 for limiting the bottom plate in place, so that the relative position of the bottom plate placed on the first bearing part 101 of the assembly flip frame 10 is accurate, so that the bottom plate is limited when it is input onto the first bearing part 101; the limit stopper 105 is connected to the assembly flip frame 10, and is not easily displaced during flipping. The front limit stopper 105 is arranged on the assembly turning frame 10 for front-back position adjustment, and the left and right limit stoppers 105 are arranged on the assembly turning frame 10 for left-right position adjustment.For example, the limit stopper 105 is installed on the support plate 108 by fasteners to adjust the position, and the long hole can be used for connection to facilitate position adjustment. In addition, the left and right sides of the horizontal paper box mold 50 are respectively provided with plate receiving recesses 52, and the plate receiving recesses 52 are respectively provided for the left and right side parts of the bottom plate to match and fold in, so as to ensure that the left and right side parts of the bottom plate are smoothly connected when the subsequent long strips are enclosed. Even the plate receiving recesses 52 can be set as grooves for the left and right side parts of the bottom plate to be folded in and supported to prevent them from falling off.

[0060] For example, the bottom plate material storehouse 13 includes left and right side plates 131 and a discharge front stopper 132. A supporting component 133 is provided at the bottom of the bottom plate material storehouse 13 to support the stacked bottom plates in the bottom plate material storehouse 13. The supporting component 133 cooperates with the left and right side plates 131 and the discharge front stopper 132 to form a material storehouse for stacking bottom plates. A single plate output gap is left between the discharge front stopper 132 and the supporting component 133 below so that a bottom plate can be output separately. The discharge front stopper 132 can block the output of other bottom plates above in front. There are many ways of the bottom plate conveying device 14, such as using a push head and / or a conveyor belt (even setting the supporting component 133 to cooperate with the conveyor belt to support and output the bottom plate), and a single-stroke or multi-stroke conveying method can be adopted. For example, the bottom plate conveying device 14 cooperates to convey the bottom plates at the bottom of the bottom plate material warehouse 13 one by one; for example, the bottom plate conveying device 14 includes a plate discharging pusher 141, which is transmission-connected with a plate discharging pushing power component 142 (such as a motor or a cylinder, etc.), and the plate discharging pusher 141 is a mature technology, and a lifting plate discharging pusher 141 or a plate discharging pusher 141 can be used, which has the function of retracting and lifting the upper side of the bottom plate in the bottom plate material warehouse 13; the first bearing part 101 on the assembly turning frame 10 located at the bottom plate feeding station cooperates with the supporting component 133 for feeding and connecting, so that the bottom plate is pushed from the supporting component 133 to the first bearing part 101; the supporting component 133 adopts a supporting plate, and the supporting plate is higher than the first bearing part 101 when cooperating with the feeding and connecting. 01 or the supporting plate is flush with the first bearing part 101; the supporting plate adopts a plane, and the first bearing part 101 adopts a plane; the supporting component 133 has a pushing channel 1331 for the board pushing head 141 to move, and the board pushing power component 142 is arranged below the supporting component 133; the discharging front stop 132 is connected to the left and right side plates 131, and the discharging front stop 132 is located at the front of the left and right side plates 131; the discharging front stop 132 is set at a height adjustment position on the left and right side plates 131 to adjust the single board output gap size to ensure the smooth output of a bottom plate; the left and right position adjustment setting of the left and right side plates 131 is adapted to bottom plates of different specifications; the bottom plate material warehouse 13 is also equipped with a tail stop component 134, and the position of the bottom plate in the material warehouse is relatively more stable and accurate.

For example, the horizontal carton mold 50 is arranged to revolve around the main rotating shaft 54 ​​arranged vertically, so as to transfer and stop at different stations to cooperate in realizing carton molding and assembly. For example, the horizontal carton mold 50 is connected to the main rotating shaft 54, and the horizontal carton mold 50 is driven by the main rotating shaft 54 ​​to rotate. The horizontal carton mold 50 is arranged to be distributed along the circumference of the main rotating shaft 54, which can adapt to the multi-station production requirements and has high efficiency, such as the four mold stop positions (i.e., four stop stations) in the figure. Among them, the main rotating shaft 54 ​​can be driven to rotate by a dividing box or the like.

[0062] For example, in this embodiment, the box body forming mechanism 2 of the long skin shell upper mold surrounding the frame connected to the box bottom plate also includes a box body long skin shell feeding device 24. In addition, the long skin shell pre-gluing device 23 includes a pre-gluing component 231 (such as a glue gun, etc.), and the pre-gluing component 231 is arranged above the conveying path of the skin shell conveying component 25. The skin shell conveying component 25 is connected to the box body long skin shell feeding device 24, and the skin shell conveying component 25 is connected to the enclosure device 22 of the long skin shell overlap enclosure mold. The long skin shell pre-gluing device 23 is arranged between the box body long skin shell feeding device 24 and the enclosure device 22; the skin shell conveying component 25 cooperates with the conveying long skin shell to convey the long skin shell. The long leather shell moves, and the leather shell conveying component 25 cooperates to convey and transfer the long leather shell supplied by the long leather shell feeding device 24 of the box body. During the conveying and transferring process, it passes through the lower position of the pre-gluing component 231, and the pre-gluing component 231 cooperates to glue the long leather shell on the conveying path. After gluing, the long leather shell is continued to be conveyed and transferred by the leather shell conveying component 25. During gluing, the leather shell conveying component 25 can stop and wait for the gluing to be completed before continuing to convey (gluing is relatively more stable), of course, it can also not stop.

[0063] For example, the box body long skin shell feeding device 24, the long skin shell pre-gluing device 23 and the enclosure device 22 are arranged in sequence along a straight line, and the skin shell conveying component 25 can convey the long skin shell along the straight line. The skin shell conveying component 25 can adopt a conveying belt or a conveying push block, and can be configured with a corresponding motor or cylinder to drive the operation.

The support plate 2213 can be equipped with a suction nozzle (capable of sucking materials) to cooperate and stably hold the long leather shell above to avoid displacement during operation.

[0064] Among them, the upper mold mechanism 221 is connected with the skin conveying component 25, that is, the skin conveying component 25 cooperates to convey the long skin strip after gluing to the upper mold mechanism 221, and can directly convey the long skin strip to the upper mold mechanism 221 or can cooperate to convey it through the skin transfer robot 26 (which can improve the conveying efficiency). As shown in the figure, the skin conveying component 25 and the enclosure device 22 are also connected with a skin transfer robot 26, which is connected and arranged between the upper mold mechanism 221 and the skin conveying component 25. The skin transfer robot 26 (such as containing a lifting suction nozzle, driven and operated by a multi-axis industrial robot arm or a lifting and translation movable frame) cooperates to transfer the long skin strip transferred by the skin conveying component 25 to the upper mold mechanism 221 (such as its support plate 2213, left and right side flaps 2214), so as to improve the connection and transmission efficiency and stability. The base 2212 of the upper mold mechanism 221 is arranged below the second mold stop position 21. In addition, during the molding and assembly process, the base 2212 can be fixed; or, a base 2212 that reciprocates inside and outside can be used, and the corresponding support plate 2213 and the left and right side flaps 2214 will move inside and outside with the base 2212, and the corresponding guide rails 22121 can be configured for guidance and power drive. The base 2212 has a material receiving position on the outside and an upper mold holding position on the inside, and the base 2212 is movable and switched between the material receiving position and the upper mold holding position; the base 2212 is connected to the skin transfer robot 26 at the material receiving position, So that the skin transfer manipulator 26 can transfer the long skin to the support plate 2213 and the left and right side flaps 2214 of the base 2212; then the base 2212 moves inward to the upper mold holding position, and the base 2212 is connected with the second mold stop position 21 at the upper mold holding position, and the support plate 2213 and the left and right side flaps 2214 on the base 2212 can cooperate with the horizontal carton mold 50 at the second mold stop position 21, and cooperate to connect and hold the long skin to the horizontal carton mold 50, and the operation efficiency is relatively fast. Among them, the horizontal carton mold 50 at the second mold stop position 21 is correspondingly arranged with the support plate 2213 below.

[0065] The upper side molding mechanism 222 of the box body is an existing mature technology. For example, the upper side molding mechanism 222 of the box body includes an upper side plate folding and pressing component 2221 and a head-to-tail overlapping pasting paper component 2222. The upper side plate folding and pressing component 2221 (which can be driven by a motor or a cylinder to run on an oblique track 2225 for oblique pressing) cooperates to fold and press a region on the edge of the long skin shell (the lower side and the left and right sides have been embraced on the horizontal paper box mold 50) toward the upper side of the horizontal paper box mold 50, so that the long skin shell is finally enclosed into a frame, and then the head-to-tail overlapping pasting paper component 2222 cooperates to overlap and paste the paper at the end of the long skin shell on the outside of the long skin shell that is enclosed into the frame, so that the head and tail ends of the long skin shell that is enclosed into the frame are glued and overlapped. Among them, the upper side plate folding and pressing component 2221 can be a folding plate or a roller, etc., and the head-to-tail overlapping pasting paper component 2222 can be a roller, etc.

[0066] This embodiment can be further optimized, the head-to-tail overlapping pasting paper component 2222 is connected to the lateral displacement driving device 2223 (which may contain a cylinder or a motor as a power), and the head-to-tail overlapping pasting paper component 2222 is also connected to the lifting pasting driving device 2224 (which may contain a cylinder or a motor as a power), that is, the head-to-tail overlapping pasting paper component 2222 can be horizontally displaced and lifted and pasted, so that it (the head-to-tail overlapping pasting paper component 2222) is horizontally moved into place for lowering the pasting paper, and the paper overlaps The pasting glue is glued to the outside of the long leather shell that forms a frame, and its horizontal movement back and upward return to a avoidance position allows the left / right side flap 2214 (on the base 2212 that embraces the upper mold mechanism 221) to smoothly flip the long leather shell to the left / right side of the horizontal paper box mold 50. In this optimized structure, the overlapping pasting position can be set on the left or right side of the horizontal paper box mold 50, which can be covered by the panel leather shell folding material later. It is not only more solid, but also the overlapping pasting position is covered and covered, making the paper box more beautiful.

[0067] In addition, the pre-gluing component 231 includes a gluing component 2311 at the overlapping portion of the face paper of the long leather shell and a gluing component 2312 at the connection portion of the long leather shell corresponding to the outside of the folded plate portions on the left and right sides of the bottom plate. The gluing component 2311 at the overlapping portion of the face paper of the long leather shell is a first gluing component, which is used to gluing the overlapping portion of the face paper of the long leather shell. The overlapping portion of the face paper of the long leather shell is located at the face paper portion at the left or right end of the long leather shell, and the face paper portion is used to be glued together when the head and tail of the long leather shell are overlapped. The gluing parts corresponding to the connection of the strip leather shell outside the folded plate parts on the left and right sides of the bottom plate are the second gluing parts, which are used to gluing the areas of the strip leather shell corresponding to the folded plate parts of the bottom plate on the left and right sides of the horizontal paper box mold 50, so that the corresponding areas of the strip leather shell can be glued to the folded plate parts on the left and right sides of the bottom plate (which have been folded to the left and right sides of the mold) on the horizontal paper box mold 50 after gluing. The first gluing part and the second gluing part can be respectively glued with a glue gun, in a horizontal movable type or a vertical movable type (same as the conveying direction of the leather shell conveying component 25), or in a horizontal or vertical arrangement mode, and can be glued horizontally and vertically on the strip leather shell according to needs.

[0068] For example, in this embodiment, the skin feeding station 32, the skin gluing station 33, and the skin turning and assembling station 34 are arranged in a straight line; The shell feeding device 35 includes a forward feeding component 351, which sequentially feeds from the shell feeding station 32 to the shell gluing station 33 and the shell flipping assembly station 34, that is, the forward feeding component 351 cooperates to feed the panel shell from the shell feeding station 32 to the shell gluing station 33, and the panel shell cooperates to be glued at the shell gluing station 33, and the forward feeding component 351 feeds the glued panel shell from the shell gluing station 33 to the shell flipping assembly station 34, and the panel shell cooperates to be flipped and assembled at the shell flipping assembly station 34. For example, the forward feeding component 351 uses a feeding belt and / or a feeding push block, for example, a feeding push block is used to push forward and retreat to a position to cooperate to push gradually. Of course, other forms 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 leather shell. The left and right side stops 352 cooperate with the left and right sides of the panel leather shell to limit the position so that the position of the panel leather shell is relatively accurate during the feeding process and is not easy to deviate left and right.

[0069] In addition, the shell gluing station 33 is provided with a shell upper side gluing device 331, in which the shell upper side gluing device 331 cooperates to glue the upper side of the panel shell. For example, the shell upper side gluing device 331 includes a transverse gluing component and / or a longitudinal gluing component, such as a glue gun as a gluing component, which cooperates to perform transverse gluing and / or longitudinal gluing on the upper side of the panel shell; transverse gluing can be performed by using a transverse shift or transverse arrangement of the transverse gluing component for transverse gluing, and longitudinal gluing can be performed by using a longitudinal shift or longitudinal arrangement of the longitudinal gluing component or by using the shell feeding device 35 to move relative to the feeding direction for longitudinal gluing. The shell upper side gluing device 331 is arranged above the feeding path of the shell feeding device 35, for example, the shell upper side gluing device 331 is located above the forward feeding component 351, so as to glue the panel shell below.

[0070] For example, the shell flip assembly station 34 is provided with a shell flip assembly device 341, which cooperates with the panel shell and flips it for joint assembly. For example, the shell flip assembly device 341 includes a flip assembly rack 342, and the flip assembly rack 342 has a second bearing portion 3421, and the second bearing portion 3421 is used to cooperate with the flip assembly of the panel shell, and the panel shell is placed on the second bearing portion 3421 and flipped and assembled. In addition, the flip assembly frame 342 is connected to the second flip shaft 343, and 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 front and back flip driving device 344 (such as containing a motor or a cylinder, etc.) for transmission. The front and back flip driving device 344 will drive the flip assembly frame 342 to flip forward (i.e., front flip) and backward (i.e., backward flip). The front and back flip driving device 344 can be directly connected to the flip assembly frame 342, and can also be connected to the flip assembly frame 342 through the second flip shaft 343, and the flipping is realized by transmission.

[0071] The flip assembly rack 342 has a shell assembly position for flipping forward and a shell input position for flipping backward; when the flip assembly rack 342 flips forward, it is the shell assembly position, that is, the flip assembly rack 342 flips the panel shell on its second bearing part 3421 and transports it to a position to be assembled on the matching horizontal carton mold 50 (on which the carton body has been formed); when the flip assembly rack 342 flips backward, it is the shell input position, which is used to input the panel shell onto its second bearing part 3421. Among them, the second bearing part 3421 of the flip assembly rack 342 is arranged corresponding to the outer side 51 of the horizontal carton mold 50 that stays at the third mold stop position 31, and the second bearing part 3421 can be flipped to the outer side 51 of the horizontal carton mold 50, and can be assembled and connected with the carton body (bottom) on the horizontal carton mold 50, and the assembly effect is relatively better.

[0072] For example, the skin feeding station 32 may be provided with a skin stacking feeding bin 321, which can stack the panel skins and place them in the skin stacking feeding bin 321 for feeding one by one. The skin feeding device 35 (such as including the forward feeding component 351) cooperates to convey the panel skins supplied from the skin stacking feeding bin 321 to the skin gluing station 33 and the skin flipping assembly station 34.

[0073] There are also many ways for the box body long skin shell feeding device 24 to supply long skin shells. For example, the box body long skin shell feeding device 24 can also include a skin shell stacking feeding bin 321, which can stack the produced long skin shells in the skin shell stacking feeding bin 321 for outputting and feeding one by one.

[0074] The shell stacking feeding bin 321 has many feeding modes and matching structures. For example, the shell stacking feeding bin 321 has a feeding port at the bottom, and the feeding port is equipped with a lifting and unloading feeding suction nozzle 322. The lifting and unloading feeding suction nozzle 322 is arranged corresponding to the feeding port, and the lifting and unloading feeding suction nozzle 322 is arranged upward. The lifting and unloading feeding suction nozzle 322 (which can be equipped with a motor or a cylinder to drive the lifting) can rise to suck the bottom layer of the shells (such as long panels or long shells) stacked in the shell stacking feeding bin 321, and then descend to move the shells downward, so that the shells can be moved and fed one by one. In addition, the bottom of the husk stacking feeding bin 321 is respectively provided with supporting edge horizontal bars 323, and the discharge port is located between the front and rear supporting edge horizontal bars 323. The supporting edge horizontal bars 323 on the front and rear sides cooperate to support the (front and rear) edges (i.e., the front and rear edge positions of the husks) stacked in the husk stacking feeding bin 321, wherein the supporting edge horizontal bars 323 can be round bars (complete round bars or incomplete round bars with cut surfaces), which are convenient for processing and support the (front and rear) edges of the stacked husks to facilitate their being sucked down and pulled for transfer. When the bottom husks are sucked down and pulled, they will be slightly deformed so that their front and rear edges are respectively separated from the corresponding supporting edge horizontal bars 323, so as to smoothly pass through (through) the discharge port and discharge downward. The husk stacking bin has a bin storage space for stacking husk materials with front and rear grooves.

[0075] In addition, a supporting rail 37 is arranged below the discharge port, and the supporting rail 37 is laid from the back to the front, and the skin conveying component 25 or the forward feeding component 351 is arranged beside the supporting rail 37, and the lifting and unloading feeding suction nozzle 322 is connected between the skin stacking feeding bin 321 and the supporting rail 37, and the skins in the bottom layer of the skin stacking feeding bin 321 can be sucked by (the lifting and unloading feeding suction nozzle 322) and moved downward to be placed on the supporting rail 37 and supported, so as to cooperate with the skin conveying component 25 or the forward feeding component 351 to transport the skins from the back to the front, for example, the supporting rail 37 adopts a supporting straight rail.

[0076] For example, the support rails 37 are laid from the skin feeding station 32 through the skin gluing station 33 to the skin flipping assembly station 34; for another example, another set of support rails 37 are laid forward from the box body long skin feeding device 24 through the long skin pre-gluing device 23 and then continue to be laid forward to connect the enclosure device 22. A positioning and limiting structure can also be set at the end of the support rails 37 to limit the position when the skin moves forward to the right position.

[0077] The feeding method of the above-mentioned shell stacking feeding bin 321 is suitable for feeding shell materials. The shell materials stacked therein are not easy to rub against each other and scratch the surface paper, and the bottom layer of shell materials of the stacked shell materials can be separated one by one and taken down for output; in addition, for materials with a groove structure (in the front and back direction) on the shell, they can also be fed and output smoothly, the shell materials can be smoothly stacked and placed in it (shell stacking bin) and sucked and taken down one by one for transfer, and can be smoothly fed forward along the supporting rail 37 (in the same direction as the groove structure on the shell material), and it is not easy for the shell materials to bend due to the grooves, affecting stacking, discharging (i.e. unloading) and forward feeding.

[0078] Even more, the shell feeding station 32 or the box body long shell feeding device 24 (or their shell stacking feeding bin 321) can be connected to the shell production equipment (which is a mature technology) to form an online connection, which can also improve the production efficiency. The shells produced by the shell production equipment (such as long panels or long shells) are directly input into the shell feeding station 32 or the box body long shell feeding device 24 for feeding.

[0079] In addition, rollers 345 for folding and rolling materials are respectively provided on the left and / or right sides of the second bearing portion 3421, and the rollers 345 are used for folding and rolling materials, wherein the rollers 345 on the left and / or right sides respectively correspond to the left and / or right sides of the horizontal paper box mold 50 staying at the third mold stop position 31, and the rollers 345 are connected to the straight-moving back-and-forth transmission component 346 for transmission, and the straight-moving back-and-forth transmission component 346 drives the rollers 345 to move back and forth on the left and / or right sides of the horizontal paper box mold 50. After the panel skin shell is turned over and assembled to the outer side surface 51 of the horizontal paper box mold 50 (at this time, the second bearing portion 3421 can cooperate with the panel to be assembled to the outer side surface 51 of the horizontal paper box mold 50), the rollers 345 on the left and / or right sides of the horizontal paper box mold 50 are connected to the straight-moving back-and-forth transmission component 346. The corresponding part of the panel skin is pressed on the outer side surface 51 of the horizontal carton mold 50. At this time, the horizontal carton mold 50 already has a carton body. The roller 345 can also fold the panel skin (except the part corresponding to the outer side surface 51 of the horizontal carton mold 50) to the left and / or right side of the horizontal carton mold 50, and while folding to the left and / or right side of the horizontal carton mold 50 (it can be glued to the left and / or right side of the carton body on the horizontal carton mold 50), it can also roll the panel skin to ensure that the panel skin is firmly and smoothly glued to the left and / or right side of the horizontal carton mold 50. In this structure, not only can the bottom of the paper box body be connected to the leather shell, but also the side walls of the paper box body (corresponding to the left and right sides of the horizontal paper box mold 50) can be connected to the leather shell, which can meet more needs and even make the paper box body more solid. After the surface shell is folded, it can be covered on the outside of the long leather shell surface paper that is overlapped and pasted, and the overlapping and pasted positions of the head and tail are covered and covered, making the paper box more beautiful.

[0080] The roller 345 can be made of rubber roller, brush roller and other materials. In addition, the roller 345 and the straight-moving back-and-forth transmission component 346 (such as a cylinder or a motor) are connected to the flip assembly frame 342, and can flip and move together with the flip assembly frame 342. The structure is reasonable, compact and easy to operate. The straight-moving back-and-forth component is located on the back of the second bearing part 3421, and is not easy to interfere with the material connection and flip assembly of the second bearing part 3421.

[0081] The outer side surface 51 of the horizontal carton mold 50 at the third mold stop position 31 cooperates with the second bearing portion 3421 when it is turned forward to the flip assembly frame 342. The horizontal carton mold 50 cooperates with the corresponding skin shell flip assembly device 341 at the third mold stop position 31, and the carton box body on the horizontal carton mold 50 can be assembled with the panel skin shell in the skin shell flip assembly device 341. The outer side surface 51 of the horizontal carton mold 50 at the third mold stop position 31 matches the second bearing portion 3421, so that the second bearing portion 3421 can more stably press the corresponding part of the panel skin shell on the outer side surface 51 of the horizontal carton mold 50, ensuring that the subsequent roller 345 folds the material more smoothly and stably, and the crease position is more neat. For example, the roller 345 used for folding and rolling the material and attaching the paper box is arranged on the roller bracket 347, and the roller bracket 347 is connected to the straight moving back and forth transmission component 346, that is, the roller 345 is connected to the straight moving back and forth transmission component 346 through the roller bracket 347, and a linear track can also be configured to make it move straightly stably. For example, the flip assembly frame 342 includes left and right flip rods 3422, and each flip rod 3422 is loosely or tightly arranged on the second flip shaft 343 (can be loosely or tightly installed and connected by fasteners), so that the position of the flip rod 3422 on the second flip shaft 343 can be adjusted after loosening, so that the spacing between the flip rods 3422 can be adjusted to adapt to the needs of paper boxes of different specifications, and then locked after adjustment to keep the flip rod 3422 and the second flip shaft 343 fixed, wherein the second bearing portion 3421 is located on the flip rod 3422, and the roller is located on the outside of the flip rod 3422, that is, the left roller is located on the left flip rod 34 22, the right roller is located on the right side of the right flip rod 3422, the roller and the straight-moving back and forth transmission component 346 are connected to the flip rod 3422, so that they can be adjusted left and right on the second flip axis 343 together with the flip rod 3422. The structure is compact and easy to use; a suction part (such as a suction hole or an air suction nozzle of an air distribution source, etc.) for sucking the skin shell is also provided at the second bearing part 3421. The suction part can cooperate with the panel skin shell to suck when the flip assembly frame 342 flips the panel skin shell to avoid displacement and falling off, thereby ensuring stable operation and relatively precise assembly. The suction part can be set on the flip rod 3422. Among them, the flip assembly frame 342 is also equipped with a limiting front stop 3423 for feeding the skin shell into place, so that when the panel skin shell is conveyed to the flip assembly frame 342 (such as the flip rod 3422), it can be more accurately positioned to improve the operating stability; for example, the limiting front stop 3423 is set on the flip rod 3422, and when the flip rod 3422 adjusts the relative position, the limiting front stop 3423 completes the position adjustment together, which is more convenient, and the limiting front stop 3423 can also support the front edge of the panel skin shell during the flipping process to prevent the panel skin shell from shifting and falling off during the flipping process.
