Description

Technical Field

[0001] This utility model relates to paper boxes, especially framed paper boxes. 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 types of paper boxes. The structure of this type of paper box (such as book-shaped boxes) includes a shell part (as a panel) and a box body part.

[0003] When making this type of cardboard box, the box body and the outer shell need to be assembled and connected. During assembly, the outer shell can be laid flat on a (horizontal) conveyor belt for transport, and then the blank box is placed on the outer 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 outer shell (top surface) can be attached and connected.

[0004] The box body can be made using a top-and-bottom box forming machine. The blank box in the top-and-bottom box forming machine is made by a corner pasting machine and then the outer paper is pasted on the outside. After that, the blank box is assembled with the outer shell to form a paper box.

[0005] To address this, a new type of cardboard box assembly and forming equipment will be designed. This equipment will require a shell assembly structure for assembling the shell and the box body. This structure will not only be compatible with this assembly and forming equipment, enriching assembly methods and providing different options, but also, during assembly, allow the shell to not only fit snugly against the bottom of the box body, but also further adhere to both sides of the box body. Utility Model Content

[0006] In view of the technical problems existing in the background art, the present invention aims to provide a paper box bottom shell assembly mechanism for assembling a shell at the bottom of a paper box body.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a paper box bottom shell assembly mechanism, including a shell feeding station, a shell gluing station, and a shell flipping assembly station, characterized in that: the shell gluing station is configured between the shell feeding station and the shell flipping assembly station, the shell feeding station, the shell gluing station, and the shell flipping assembly station are connected by a shell feeding device, and the shell flipping assembly station is equipped with a mold stopping position; the mold stopping position is equipped with a horizontal paper box mold for paper box assembly.

[0008] The following optimizations or supplementary explanations can be made to the above technical solutions.

[0009] The horizontal paper box mold has vertically arranged left, right, and outer sides. The inner side of the horizontal paper box mold corresponds to the box opening, and the outer side of the horizontal paper box mold corresponds to the box bottom. The horizontal paper box mold revolves around the main rotating shaft, which is vertically arranged. The horizontal paper box mold is connected to the main rotating shaft and is distributed circumferentially along the main rotating shaft. The horizontal paper box mold rotates to the mold stopping position and pauses intermittently.

[0010] For example, the shell feeding station, the shell gluing station, and the shell flipping assembly station are arranged in a straight line; the shell feeding device includes a forward feeding component that feeds materials sequentially from the shell feeding station to the shell gluing station and the shell flipping assembly station; 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 shell feeding limits.

[0011] For example, the shell gluing station is equipped with a shell upper side gluing device; the shell upper side gluing device includes a transverse gluing component and / or a longitudinal gluing component, the shell upper side gluing device is configured above the feeding path of the shell feeding device, and the shell upper side gluing device is located above the forward feeding component.

[0012] For example, a shell flipping and assembly station is equipped with a shell flipping and assembly device. For example, the shell flipping and assembly device includes a flipping assembly frame, which is connected to a flipping shaft. The axis of the flipping shaft is set horizontally. The flipping assembly frame is connected to a forward and backward flipping drive device. The flipping assembly frame has a support part for carrying the shell flipping and assembly. The flipping assembly frame has a shell assembly position for forward flipping and a shell input position for backward flipping.

[0013] The support unit is positioned to correspond to the outer side of the horizontal cardboard box mold at the mold's stopping position. Further optimization is possible: the left and / or right sides of the support unit are also equipped with rollers for folding and rolling material. These rollers correspond to the left and / or right sides of the horizontal cardboard box mold at the mold's stopping position. The rollers are connected to a linear reciprocating drive component, which is connected to a flipping assembly frame. The linear reciprocating drive component is located on the back of the support unit.

[0014] The horizontal cardboard box mold is positioned to receive the casing flipping assembly device. The outer surface of the horizontal cardboard box mold at the mold's stopping position matches the supporting part. Rollers for folding, rolling, and attaching the casing to the cardboard box are mounted on a cylindrical support. The cylindrical support is connected to a linear reciprocating transmission component. The flipping assembly frame includes left and right flipping rods, each with a tension setting on a flipping shaft. The supporting part is located on the flipping rods, and rollers are located on the outer side of the flipping rods. The rollers and the linear reciprocating transmission component are connected to the flipping rods. A suction unit for holding the casing is also provided at the supporting part; the suction unit is mounted on the flipping rods. The flipping assembly frame is also equipped with a limiting front stop for casing feeding; the limiting front stop is mounted on the flipping rods.

[0015] Additional explanation: The outer side of the horizontal cardboard box mold at the mold stopping position mates with the support part when the flip assembly frame is flipped into place.

[0016] Further optimizations include a shell feeding station equipped with a shell stacking feeding hopper or a shell production equipment. The bottom of the shell stacking feeding hopper has a discharge port, which is equipped with a lifting and lowering discharge nozzle. The lifting and lowering discharge nozzle is set corresponding to the discharge port and faces upward. A conveying support rail is laid from the shell feeding station to the shell gluing station and then to the shell flipping assembly station. The conveying support rail is located below the discharge port. The lifting and lowering discharge nozzle is connected between the shell stacking feeding hopper and the conveying support rail. The conveying support rail is a straight support rail. The forward feeding component of the shell feeding device is configured on the side of the conveying support rail.

[0017] In addition, the bottom of the stacked hopper is equipped with horizontal support bars at the front and rear, and the discharge port is located between the front and rear horizontal support bars. For example, the horizontal support bars are round bars.

[0018] The beneficial effects of this utility model are that, unlike the method of assembling the box body onto the outer shell, it uses a method of flipping the outer shell and assembling it onto the box body of the horizontal box mold, providing a completely new assembly method and enriching the assembly options to meet more needs. The panel and outer shell adhesive box assembly mechanism is used to adhesively attach the panel and outer shell to the box body (already positioned in the mold) (located on the outer perimeter of the box body), completing the box assembly. The panel and outer shell can also serve as the box lid and outer panel, folding over and covering the outside of the box body, forming a book-shaped box structure. Attached Figure Description

[0038] 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.

[0039] Referring to the accompanying drawings, the paper box bottom shell assembly mechanism in this embodiment includes a shell feeding station 32, a shell gluing station 33, and a shell flipping assembly station 34. The shell gluing station 33 is located 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 (i.e., the material with face paper pasted on the surface of the cardboard, which can be referred to as the shell) from the shell gluing station 33 to the shell flipping assembly station 34.

[0040] The panel shell is supplied at the shell feeding station 32; the panel shell is glued at the shell gluing station 33 so that it can be glued to the box body on the horizontal cardboard mold 50. The box body has been pre-placed on the horizontal cardboard mold 50 (or pre-made and placed on other mechanisms); the panel shell is flipped onto the horizontal cardboard mold 50 (stopped at the mold stopping position 31) at the shell flipping assembly station 34 to complete the assembly of the shell with the bottom of the box body (on the horizontal cardboard mold 50).

[0041] The casing flipping assembly station 34 is equipped with a mold stopping position 31, so that the horizontal cardboard box mold 50 can cooperate at the mold stopping position 31 to complete the casing flipping assembly, receive the casing, and cooperate to realize the assembly connection between the casing and the cardboard box body.

[0042] This structural layout differs from the method of assembling the box body onto the outer shell. Instead, the outer shell is flipped and assembled onto the box body of the horizontal box mold 50, providing a completely new assembly method that enriches assembly options and meets more needs. The panel and outer shell gluing assembly mechanism is used to glue the panel and outer shell to the box body (already positioned in the mold) (located on the outer perimeter of the box body), completing the box assembly. The panel and outer shell can also serve as the box lid and outer panel, folding over and covering the outside of the box body, forming a book-shaped box structure.

[0043] Based on the above embodiments, the following optimizations or further explanations can be made.

[0044] For example, the left and right sides and outer side 51 of the horizontal cardboard box mold 50 are all vertically arranged. The inner side of the horizontal cardboard box mold 50 corresponds to the box opening, and the outer side 51 of the horizontal cardboard box mold 50 corresponds to the box bottom, forming a horizontal structure. The horizontal cardboard box mold 50 revolves around the main rotating shaft 54, which is vertically arranged, so as to move and stop at different workstations to cooperate in the production of the framed cardboard box. The horizontal cardboard box mold 50 is connected to the main rotating shaft 54, which drives the horizontal cardboard box mold 50 to rotate. The horizontal cardboard box mold 50 is distributed around the circumference of the main rotating shaft 54, which can adapt to the production needs of multiple workstations. The horizontal cardboard box mold 50 rotates to the mold stopping position 31 and stops intermittently to cooperate with the corresponding workstation.

[0045] The casing feeding station 32, casing gluing station 33, and casing flipping assembly station 34 are arranged in a straight line. The casing feeding device 35 includes a forward feeding component 351, which sequentially feeds the casing 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 uses a feeding belt and / or a feeding pusher, such as a feeding pusher driven by a corresponding motor to push forward and backward step by step. Of course, other methods 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 cooperate to limit the left and right sides of the panel shell so that the position of the panel shell is relatively accurate during the feeding process and is not easy to shift to the left or right.

[0046] In addition, the casing gluing station 33 is equipped with a casing upper side gluing device 331, which works in conjunction with the casing upper side gluing device 331 to apply glue to the upper side of the panel casing. 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 perform horizontal and / or vertical gluing on the upper side of the panel casing; horizontal gluing can be performed by using a horizontally moving or horizontally arranged horizontal gluing component, and vertical gluing can be performed by using a vertically moving or vertically arranged vertical gluing component, or by using the relative movement of the casing feeding device 35 in the feeding direction to perform vertical gluing. The horizontal or vertical movement can be driven by a linear module. The casing upper side gluing device 331 is positioned above the feeding path of the casing feeding device 35, for example, the casing upper side gluing device 331 is located above the forward feeding component 351, so as to apply glue to the panel casing below.

[0047] The casing flipping assembly station 34 is equipped with a casing flipping assembly device 341, which receives and flips the panel casing for assembly. For example, the casing flipping assembly device 341 includes a flipping assembly frame 342 connected to a flipping shaft 343. The flipping assembly frame 342 flips back and forth around the flipping shaft 343, which is horizontally oriented. The flipping assembly frame 342 is connected to a forward and backward flipping drive device 344 (such as a motor or cylinder). The forward and backward flipping drive device 344 drives the flipping assembly frame 342 to flip forward (i.e., forward flip) and backward (i.e., backward flip). The forward and backward flipping drive device 344 can be directly connected to the flipping assembly frame 342 or connected to the flipping assembly frame 342 through the flipping shaft 343 to achieve flipping through the transmission.

[0048] The flip assembly frame 342 has a support part 3421, which is used to cooperate with the flip assembly of the panel shell. The panel shell (a material with paper pasted on the surface of the cardboard, which can be simply referred to as the shell) is placed on the support part 3421 and then flipped for assembly. The flip assembly frame 342 has a shell assembly position when it is flipped forward and a shell input position when it is flipped backward. When the flip assembly frame 342 is flipped forward, it is the shell assembly position, that is, the flip assembly frame 342 flips and transports the panel shell on its support part 3421 into position for assembly on the matching horizontal cardboard box mold 50 (a cardboard box can be pre-placed or made). When the flip assembly frame 342 is flipped backward, it is the shell input position, which is used to input the panel shell onto its support part 3421.

[0049] Among them, the bearing part 3421 of the flip assembly frame 342 is correspondingly provided with the outer side 51 of the horizontal paper box mold 50 which is stopped at the mold stopping position 31. The bearing part 3421 can be flipped to the outer side 51 of the horizontal paper box mold 50 and can be assembled with the paper box body (box bottom) on the horizontal paper box mold 50, and the assembly effect is relatively better.

[0050] In addition, the left and / or right sides of the support part 3421 are respectively provided with rollers 345 for folding and rolling materials. The rollers 345 are used for folding and rolling materials. The left and / or right rollers 345 correspond to the left and / or right sides of the horizontal paper box mold 50, which is stopped at the 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 paper box mold 50. After the panel shell is flipped and assembled onto the outer side 51 of the horizontal paper box mold 50 (at this time, the support part 3421) 1. The roller 345 can press the corresponding part of the panel shell onto the outer side 51 of the horizontal paper box mold 50. It can also fold the panel shell (excluding the part corresponding to the outer side 51 of the horizontal paper box mold 50) towards the left and / or right side of the horizontal paper box mold 50. While folding it towards the left and / or right side of the horizontal paper box mold 50 (ensuring adhesive bonding with 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 a firm and flat adhesive bond between the panel shell and the left and / or right side of the left and / or right side of the horizontal paper box mold 50. This structure not only allows the bottom of the paper box body to connect with the corresponding shell, but also allows connection between the side wall of the paper box body and the shell, meeting more needs. The roller 345 can be made of materials such as a glue roller or a brush roller. In addition, the roller 345 and the linear reciprocating transmission component 346 (such as a cylinder or motor) are connected to the flipping assembly frame 342, and can flip and move together with the flipping assembly frame 342. The structure is reasonable, compact and easy to operate. The linear reciprocating component is located on the back of the bearing part 3421, so it is not easy to interfere with the material receiving and flipping assembly of the bearing part 3421.

[0051] The outer side 51 of the horizontal cardboard box mold 50 at the mold stopping position 31 mates with the support part 3421 when it is flipped into position towards the flip assembly frame 342. The horizontal cardboard box mold 50 at the mold stopping position 31 corresponds to the receiving part of 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 mold stopping position 31 matches the support part 3421 so that the 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 position. 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 for 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) on a flip shaft 343, allowing adjustment of its position on the flip shaft 343 after loosening. This adjusts 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 flip shaft 343. A support 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 the rotating rod 3422, the rollers and the linear reciprocating transmission component 346 are connected to the rotating rod 3422 so that they can be adjusted left and right together with the rotating rod 3422 on the rotating shaft 343. The structure is compact and easy to use. The bearing part 3421 is also provided with a suction part (such as an air intake hole or air nozzle for air supply) for holding the shell. The suction part can help hold the panel shell when the rotating assembly frame 342 flips 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 rotating 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 conveyed to the flip assembly frame 342 (such as the flip rod 3422), it can be placed more accurately and improve the stability of operation. For example, the limiting front stop can be set on the flip rod 3422. When the flip rod 3422 adjusts its relative position, the limiting front stop also completes the position adjustment, which is more convenient. It can also support the front edge of the panel shell during the flipping process, preventing the panel shell from shifting and falling off during the flipping process.

[0052] In addition, the shell feeding station 32 can be connected to the shell production equipment (a mature technology) to form an online system, which can also improve production efficiency. The panel shells produced by the shell production equipment are directly input into the shell feeding station 32. The shell feeding device 35 (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. Alternatively, the shell feeding station 32 can be equipped with a shell stacking feeding bin 321, in which the produced panel shells are stacked and placed for output feeding one by one. For example, the shell feeding station 32 is equipped with a shell stacking feeding bin 321. 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 upward. The lifting and lowering feeding nozzle 322 (which can be driven by a motor or cylinder, etc.) rises to pick up the bottom layer of the panel shells stacked in the shell stacking feeding bin 321, and then descends to move the shell downwards. This can move the shells one by one. The shell feeding station 32 is connected to the shell gluing station 33 and the shell flipping and assembly station 34 by a conveyor tray. The material rails 37, one after another, can support the panel shell so that the panel shell can be fed forward by the shell feeding device 35 (such as its feeding push block, etc.). The material rails 37 are located below the discharge port. The lifting and lowering discharge suction nozzle 322 is connected between the shell stacking feeding bin 321 and the material rails 37. The bottom layer of the shell stacking feeding bin 321 can be sucked up and moved down to the material rails 37. For example, the material rails 37 are straight rails. The forward feeding component 351 of the shell feeding device 35 is arranged on the side of the material rails 37. In addition, the bottom of the shell stacking feeding bin 321 is equipped with material-supporting edge horizontal bars 323 at the front and back respectively. The discharge port is located between the front and back material-supporting edge horizontal bars 323. The front and back material-supporting edge horizontal bars 323 cooperate to support the (front and back) edges (i.e. the front and back edges of the shell) of the panel shell stacked in the shell stacking feeding bin 321. The material-supporting edge horizontal bars 323 can be round bars (either complete round bars or incomplete round bars with cut surfaces), which is convenient for processing and facilitates the suction and downward transfer of the (front and back) edges of the stacked panel shell after it is supported. When the bottom layer of the panel shell is suctioned and pulled down, it will deform slightly so that its front and back edges are separated from the corresponding material-supporting edge horizontal bars 323, thus smoothly passing through the discharge port and being discharged downward.
