Description

Technical Field

[0001] This invention relates to the field of cigarette box processing technology, and specifically discloses a fully automatic carton assembly equipment that integrates processes such as applying glue to the outer shell, assembling and molding the inner box, molding the inner box, and applying greaseproof paper. Background Technology

[0002] Cigarette packaging is mainly divided into carton packaging and individual box packaging. Some high-end cigarette cartons also have a leather outer layer and a kraft paper inner layer on the side walls. (See attached image) Figures 1-3 The carton shown is assembled from a casing a, an inner box b containing an inner mold d, and kraft paper c. One end of the casing a is glued to the bottom wall of the inner box b, and the other end of the casing a is glued to the lid. The casing a and the inner box b are fixed together at the opening position by magnetic attraction. However, for this type of carton with a special structure, the assembly of the inner box with the casing and kraft paper still requires semi-automation or manual assembly in the existing technology, resulting in low processing efficiency.

[0003] Utility model patent application number 202023134041.X discloses an automatic cigarette box forming machine, which includes a frame, a feeding channel, and a multi-stage linkage pushing mechanism that pushes materials step by step along the feeding channel. Along the feeding direction of the feeding channel, the frame is sequentially equipped with an outer shell feeding mechanism, an adhesive screen printing mechanism for applying adhesive to the outer shell, a hot air drying mechanism for drying the adhesive, an outer shell and inner box assembly mechanism for assembling the inner box at the adhesive application point of the outer shell, and a folding mechanism for folding the formed sides and flap of the outer shell. The outer shell and inner box assembly mechanism includes an inner box storage station and a box-holding feeding mechanism that moves the inner box from the storage station to the feeding channel. Although the automatic cigarette box forming machine disclosed in this patent has the functions of applying adhesive to the outer shell and bonding the outer shell to the inner box, the structure of the cigarette box described is different from that of the carton to be assembled in this application, and therefore it is not applicable to the carton to be assembled and processed in this application. Furthermore, the inner box of the cigarette pack lacks an internal mold during the molding process, resulting in poor overall structural strength. It is prone to deformation during the folding mechanism's bonding and pressing process with the outer shell, and it also lacks the function of attaching kraft paper for internal assembly. Therefore, this application proposes a fully automated carton assembly device that integrates shell gluing, inner box assembly, inner box demolding, and kraft paper application, thereby achieving fully automated and efficient assembly of the cartons required for this application. Summary of the Invention

[0004] The purpose of this invention is to provide a fully automatic carton assembly equipment that integrates processes such as applying adhesive to the outer shell, assembling and molding the inner box, molding the inner box, and applying greaseproof paper, so as to realize the fully automated assembly and production of packaging cartons, thereby ensuring the assembly efficiency of the cartons and the quality of the processed products.

[0005] This invention is achieved through the following technical solution: A carton assembly device includes a shell gluing unit, a shell inner box assembly and forming unit, an inner box demolding unit, and a greaseproof paper pasting unit. The discharge end of the shell gluing unit is connected to the shell inner box assembly and forming unit. The discharge end of the shell inner box assembly and forming unit is connected to the inner box demolding unit via a first conveying unit. The discharge end of the inner box demolding unit is connected to the greaseproof paper pasting unit via a second conveying unit.

[0006] As a further provision of the above scheme, the shell coating unit includes a first base, on which a conveyor belt is provided. A shell hopper is provided above the end of the conveyor belt on the side away from the shell inner box assembly unit, and a feeding mechanism is provided at the bottom of the shell hopper. A first glue spraying mechanism and a second glue spraying mechanism are sequentially provided above the middle position of the conveyor belt.

[0007] As a further provision of the above solution, the inner box assembly unit includes a second base. The upper surface of the second base is provided with an inner box feeding station and a four-sided bubble pressing mechanism at both ends. A station rotation mechanism is provided between the inner box feeding station and the four-sided bubble pressing mechanism. Two segmented outer box positioning slots are symmetrically arranged on the station rotation mechanism. A first conveying mechanism is provided between the outer box gluing unit and the inner box assembly unit. The first conveying mechanism grabs the glued outer box and places it in the segmented outer box positioning slot at the rear. An inner box conveying mechanism is provided between the inner box feeding station and the segmented outer box positioning slot at the front.

[0008] As a further feature of the above solution, the segmented shell positioning groove includes a fixed section fixed on the rotary table and a movable section that can be raised and lowered. The station rotation mechanism is provided with a lifting drive component for driving the movable section to move up and down. A pressing component is provided directly above the movable section in the segmented shell positioning groove at the front. A forming channel is provided directly below the segmented shell positioning groove at the front. The entrance end of the forming channel is located directly below the docking point of the fixed section and the movable section. The exit end of the forming channel is aligned and connected with the inlet of the four-sided bubble pressing mechanism. A linear module pushing component is provided on the second base to push the inner box on the movable section into the forming channel.

[0009] As a further provision of the above scheme, a first brush roller is provided between the inlet end of the forming channel and the segmented shell positioning groove, and a second brush roller is provided at the upper end of the inner cavity of the forming channel.

[0010] As a further provision of the above scheme, the inner box molding unit includes a third base, on which a conveyor chain for conveying workpieces is provided. A second handling mechanism for placing workpieces on the conveyor chain is provided between the first conveying unit and the inner box molding unit. An opening mechanism parallel to the conveyor chain and realizing the gradual opening of the box lid is provided on the third base. A molding mechanism is provided directly above the end of the opening mechanism.

[0011] As a further feature of the above solution, the box opening mechanism includes an open surface opening component, a support guide slide, a cylinder push plate push component, and a support holding slide, arranged in sequence, and a cylinder top plate is provided below the open surface opening component.

[0012] As a further feature of the above solution, the mold-removing mechanism includes a bracket disposed above the support rod, with a lower mold slide and a push mold assembly respectively disposed at the front and rear ends of the bracket, and a gripping assembly disposed between the lower mold slide and the push mold assembly, which moves downward to grip the inner mold in the inner box.

[0013] As a further provision of the above solution, the greaseproof paper applicator includes a greaseproof paper hopper, a sorting station, a transfer adhesive applicator platform, a double-sided adhesive applicator, a reciprocating oscillating mechanism, and an inner applicator brush roller mechanism. A suction cup gripping assembly for gripping and releasing greaseproof paper is provided between the greaseproof paper hopper and the sorting station. The reciprocating oscillating mechanism has a first greaseproof paper suction mold that rotates and switches between the sorting station and the transfer adhesive applicator platform, and a second greaseproof paper suction mold that rotates and switches between the transfer adhesive applicator platform and the greaseproof paper applicator station. The double-sided adhesive applicator is located at the side of the transfer adhesive applicator platform for applying adhesive to the protruding part of the greaseproof paper. The inner applicator brush roller mechanism is located at the end of the second greaseproof paper suction mold for pressing the adhesive-applied part of the greaseproof paper against the inner box end wall.

[0014] As a further feature of the above solution, the inner pasting brush roller mechanism includes a mounting base fixed to the end of the second absorbent paper mold, and a pressing cylinder is provided on the mounting base. The lower end of the pressing cylinder is connected to a third brush roller that presses the end of the pasting paper after it has been pasted with adhesive into the end wall of the inner box.

[0015] In the operation of the carton assembly equipment disclosed in this invention, the conveyor belt in the shell coating unit transports the shells that fall one by one from the shell hopper toward the shell inner box assembly unit. During the transportation process, multiple shells on the conveyor belt are evenly spaced. Then, when the shells pass through the first glue spraying mechanism and the second glue spraying mechanism, the first glue coating surface and the second glue coating surface on the shell are coated successively.

[0016] When the coated shell is transported to one end of the inner box assembly unit, the first transport mechanism grabs the shell (grabs the non-coated area on the shell) and places it in the segmented shell positioning slot at the rear. Then, the segmented shell positioning slot loaded with the coated shell is rotated 180° by the station rotation mechanism, thereby rotating it to the front and placing it above the forming channel.

[0017] Next, the inner box handling mechanism grabs the inner box from the inner box loading station (at this time, the inner box is in a closed state, and an inner mold is installed inside to ensure the structural strength of the inner box). The grabbed inner box is then neatly placed on the movable section of the segmented shell positioning groove. Under the action of the pressing component, the bottom wall of the inner box and the first adhesive surface of the shell are pressed and bonded together with adhesive. Subsequently, under the action of the lifting drive component, the movable section in the segmented shell positioning groove is pushed downwards. At this time, the other parts of the shell, originally located on the fixed section in the segmented shell positioning groove, move downwards accordingly and are folded under the action of the first brush roller until the shell is aligned with the forming channel. After alignment, the linear module pushing component is activated. Under the action of the linear module pushing component, the inner box and the shell are pushed together into the forming channel. Then, as it moves in the forming channel, the second adhesive surface of the shell is pressed against the upper surface of the inner box lid under the action of the second brush roller. Finally, the assembly (i.e., the combination of inner box + outer shell + inner mold) sent out from the molding channel will enter the four-sided bubble pressing mechanism, which will then apply pressure to the outer shell of the inner box to expel air from the adhesive area and ensure the bonding effect between the outer shell and the inner box.

[0018] After four-sided bubble pressing, the assembled component falls onto the first conveyor unit, which transports it to one end of the inner box mold-taking unit. The second transport mechanism then grabs the component and places it in the slot of the conveyor chain. Under the conveyor chain's transport, the component sequentially passes through the opening mechanism's opening component, guide slide, cylinder push plate, and holding slide until it is directly below the mold-taking mechanism. At this point, the box lid is fully opened. The mold-taking mechanism then moves down to grab the inner mold from the inner box and lifts it between the lower mold slide and the push mold component. The push mold component then pushes the lifted inner mold into the lower mold slide, through which the inner mold is exported from the entire device for recycling. Simultaneously, the inner box, with the inner mold removed and the top opened, is transferred to the second conveyor unit, which then transports it to the linerboard application station in the linerboard application unit for positioning.

[0019] During operation, the tracing unit uses a suction cup gripper to pick up the tracing paper from the top layer of the tracing paper hopper, then places it on the sorting station and pats it neatly. A reciprocating oscillating mechanism then rotates the first tracing paper mold to directly above the sorting station, where it picks up the tracing paper. The first mold then rotates in the opposite direction to a transfer adhesive application platform, with the end of the tracing paper extending a certain length beyond the platform. A double-sided tape application mechanism then applies double-sided tape to the extended end of the tracing paper. After adhesive application, the second tracing paper mold picks up the tracing paper, while the first mold returns to directly above the sorting station to await the next sheet of tracing paper.

[0020] Finally, the adhesive-coated greaseproof paper, grasped by the second suction greaseproof paper mold, rotates under the action of the reciprocating oscillating mechanism to be directly above the greaseproof paper application station. Then, the inner application brush roller mechanism is activated, so that the end of the greaseproof paper with double-sided adhesive is pressed onto the end wall of the inner box under the combined action of the pressing cylinder and the third brush roller, thus completing the final carton processing step. The finally assembled carton is then sent out for collection by the second conveying unit.

[0021] Compared with the prior art, the present invention has the following beneficial effects: The carton assembly equipment disclosed in this invention is specially designed for packaging cartons with special structures. It realizes the automated assembly of the outer shell, inner box, and kraft paper, replacing manual processing. This not only greatly improves the production and assembly efficiency of packaging cartons, but also ensures product consistency and effectively guarantees the final product quality.

[0022] The carton assembly equipment disclosed in this invention, during the adhesive bonding process between the outer shell and the inner box, incorporates an inner mold within the inner box to increase its structural strength. This allows for greater pressure to be applied after the outer shell and inner box are bonded, ensuring a strong adhesion while maintaining the shape of the inner box. Combined with subsequent opening and mold-removing mechanisms, the inner mold can be automatically removed and recycled. After the inner mold is removed, the process of pasting kraft paper can then commence. The entire carton assembly equipment features a fully automated process, a relatively compact overall structure, low processing efficiency, and excellent processing results. It represents a first-of-its-kind design in the industry for this type of packaging carton assembly. Attached Figure Description

Detailed Implementation

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-15This application will be described in detail with reference to the embodiments. Example 1

[0027] Example 1 discloses a carton assembly device, which is described below with reference to the appendix. Figures 1-3 First, let's describe the specific components and structure of the carton. It includes an inner box a, a outer shell b, kraft paper c, and an inner mold d. The outer shell b includes a first adhesive surface ba that adheres to the bottom wall of the inner box a, a second adhesive surface bb that adheres to the upper surface of the lid of the inner box a, an open surface bc that magnetically attracts the end face of the inner box a, and a hinge-like movable folding surface bd. The inner mold d is installed inside the inner box a. After removing the inner mold d, the kraft paper c is then adhered to the inner end wall of the inner box a.

[0028] Reference Appendix Figure 4 The main structure of the assembly equipment includes a shell gluing unit 100, a shell inner box assembly and forming unit 200, an inner box demolding unit 300, and a kraft paper pasting unit 400. The discharge end of the shell gluing unit 100 is connected to the shell inner box assembly and forming unit 200. The discharge end of the shell inner box assembly and forming unit 200 is connected to the inner box demolding unit 300 via a first conveying unit 500. The discharge end of the inner box demolding unit 300 is connected to the kraft paper pasting unit 400 via a second conveying unit 600.

[0029] Reference Appendix Figure 5 The casing adhesive application unit 100 includes a first base 101, on which a conveyor belt 102 is mounted. A casing hopper 103 is located above the end of the conveyor belt 102 on the side away from the casing inner box assembly unit 200. The bottom of the casing hopper 103 is equipped with a feeding mechanism that allows casings to be discharged one by one. The feeding mechanism can discharge the stacked casings in the casing hopper 103 one by one from the bottom, and then they fall onto the conveyor belt 102. The conveyor belt 102 then transports the casings toward the casing inner box assembly unit 200.

[0030] A first glue-spraying mechanism 104 and a second glue-spraying mechanism 105 are spaced apart on a first base 101 located above the middle position of the conveyor belt 102. Both the first glue-spraying mechanism 104 and the second glue-spraying mechanism 105 consist of an XY-axis moving assembly, a lifting cylinder, and a glue-spraying head. To ensure efficient glue spraying of the casing, both mechanisms have two glue-spraying heads, and the distance between the two heads is equal to the distance between two adjacent casings on the conveyor belt 102. During operation, when a casing on the conveyor belt 102 is transported to the position of the first glue-spraying mechanism 104, the first glue-spraying mechanism 104 sprays glue at the first glue-spraying position (i.e., the first adhesive surface ba) on the casing. After the first glue-spraying position is completed, the conveyor belt 102 transports the casing to the position of the second glue-spraying mechanism 105, where the second glue-spraying mechanism 105 sprays glue at the second glue-spraying position (i.e., the second adhesive surface bb) on the casing. Finally, after the adhesive is applied, the outer shell is picked up by the first conveying mechanism 700 between the outer shell adhesive application unit 100 and the outer shell inner box assembly unit 200 and placed onto the outer shell inner box assembly unit 200.

[0031] Reference Appendix Figures 6-10 The inner box assembly unit 200 includes a second base 201. The upper surface of the second base 201 has an inner box feeding station 202 and a four-sided bubble pressing mechanism 203 respectively at both ends. A station rotation mechanism 204 is located between the inner box feeding station 202 and the four-sided bubble pressing mechanism 203. The inner box feeding station 202 is connected to an external inner box feeding machine (not shown in the figure) at one end, allowing the inner boxes to be conveyed one by one to the inner box feeding station 202 to await being picked up. The station rotation mechanism 204 consists of a rotary table and a cam divider, allowing the rotary table to rotate 180° each time under the action of the cam divider. Two rotationally symmetrical segmented housing positioning slots 205 are provided on the rotating platform. The rear segmented housing positioning slot 205 is used to receive the housing conveyed by the first conveying mechanism 700, and the front segmented housing positioning slot 205 interacts with the gripped inner box to complete the bonding between the bottom wall of the inner box and the first adhesive surface ba on the housing.

[0032] In the specific design, the segmented housing positioning groove 205 is divided into a fixed section 2051 fixed on the rotating table and a movable section 2052 that can be raised and lowered. The rotating table is provided with a lifting drive component 206 for driving the movable section 2052 to move up and down. At the same time, a pressing component 212 is provided directly above the movable section 2052. The pressing component 212 is composed of a slide rail, a synchronous belt, a pressing vertical wall, and a pressure plate. An inner box transport mechanism 207 is set between the inner box loading station 202 and the segmented outer shell positioning groove 205 in front. Specifically, the inner box transport mechanism 207 consists of a linear motion module, a lifting cylinder, and a clamp. When the inner box is transported to the inner box loading station 202, the inner box transport mechanism 207 grabs the inner box and then moves the inner box to the top of the segmented outer shell positioning groove 205 through the linear motion module, so that the bottom wall of the inner box is precisely aligned with the movable section 2052. Then, the lifting cylinder pushes the inner box downward, so that the bottom wall of the inner box is adhered to the outer shell of the movable section 2052.

[0033] A forming channel 208 is provided directly below the segmented shell positioning groove 205 at the front. The entrance end of the forming channel 208 is located directly below the junction of the fixed section 2051 and the movable section 2052, while the exit end is aligned and connected to the inlet of the four-sided bubble pressing mechanism 203. Simultaneously, a first brush roller 209 is provided between the entrance end of the forming channel 208 and the segmented shell positioning groove 205, and multiple second brush rollers 210 are spaced apart at the upper end of the inner cavity of the forming channel 208. Finally, a linear module pushing assembly 211 for pushing the inner box into the forming channel 208 is provided on the second base 201. After the bottom wall of the inner box adheres to the first adhesive surface ba of the outer shell on the movable section 2052, the lifting drive 206 and the pressing component 212 are activated to move the movable section 2052 downwards until it is aligned with the forming channel 208. During the downward movement of the movable section 2052, the outer shell portion (i.e., the movable folding surface bd + the second adhesive surface bb + the open surface bc) originally located on the fixed section 2081 is folded over by the action of the first brush roller 209. After the folding is completed, the linear module push component 211 pushes the assembly (i.e., the outer shell + the inner box, hereinafter referred to as the assembly) after the outer shell and the inner box are adhered into the molding channel 208. During the molding channel 208, the second brush roller 210 can adhere and press the outer shell, the bottom wall of the inner box, and the upper surface of the lid together. After entering the four-sided bubble pressing mechanism 203, the cylinder on the four-sided bubble pressing mechanism 203 pushes the pressure plate to further press the outer shell and the inner box together, expelling the air at the pressing point and ensuring the adhesion effect between the outer shell and the inner box. Finally, the assembly after four-sided bubble pressing falls into the first conveying unit 500, and is conveyed to one side of the inner box demolding unit 300 by the first conveying unit 500, and then conveyed to the inner box demolding unit 300 by the second transport mechanism 800.

[0034] Reference Appendix Figure 11 and attached Figure 12 The inner box molding unit 300 includes a third base 301, on which two parallel conveyor chains 302 are provided, and multiple positioning clips are equally spaced on the two conveyor chains 302, so that a locking position for fixing the assembly is formed between two adjacent sets of positioning clips. During operation, the second handling mechanism 800 grabs the assembly on the first conveyor unit 500 and places it in the locking position, and then the conveyor chain 302 transports it.

[0035] An opening mechanism is provided on the third base 301 parallel to the conveying path of the conveyor chain 302. The opening mechanism includes, in sequence, an open surface opening component (not shown in the figure), a spreading guide slide 304, a cylinder push plate pushing component 305, and a spreading and holding slide 306. A mold taking mechanism 307 is provided directly above the spreading and holding slide 306. When the assembly is conveyed to the open surface opening component by the conveyor chain 302, the open surface opening component opens the open surface bc on the shell to a certain angle by magnetic attraction or other adsorption methods. Then, the cylinder top plate 303 at the bottom spreads the open surface bc of the shell open, so that the open surface smoothly enters the outside of the spreading guide slide 304. Under the action of the spreading guide slide 304, the opening angle of the open surface gradually increases. When the assembly moves to the position of the cylinder push plate push-open component 305, the cylinder push plate pushes open component 305 to completely open the inner box cover. The opened box cover is located outside the support and holding slide bar 306, so that the entire assembly can move to the underside of the mold taking mechanism 307 while maintaining an open state.

[0036] The specific mold-removing mechanism 307 includes a support 3071. A lower mold slide 3072 and a mold-pushing assembly 3073 are respectively provided at the front and rear ends of the support 3071. A gripping assembly 3074, which can move downwards to grip the inner mold in the inner box, is provided between the lower mold slide 3072 and the mold-pushing assembly 3073. When the assembled component with the box lid open moves to directly below the gripping assembly 3074 under the action of the conveyor chain 302, the gripping assembly 3074 grips the upper end of the inner mold in the inner box, and then raises it to a horizontal height aligned with the lower mold slide 3072 and the mold-pushing assembly 3073. Finally, the mold-pushing assembly 3073 pushes the gripped inner mold into the lower mold slide 3072, which then orients and recycles the inner mold. The assembled component after removing the inner mold is received by the second conveying unit 600 and transported by the second conveying unit 600 to the position of the greaseproof paper pasting unit 400.

[0037] Reference Appendix Figures 13-15The kraft paper pasting unit 400 includes a kraft paper hopper 401, a sorting station 402, a transfer pasting platform 403, a reciprocating swing mechanism 404, and an inner pasting brush roller mechanism 406. A suction cup gripping component 407 is provided between the kraft paper hopper 401 and the sorting station 402. The suction cup gripping component 407 consists of a linear motion module, a cylinder, and a suction cup. It can adsorb and grip the kraft paper on the top layer of the kraft paper hopper 401 one sheet at a time, and then place it on the sorting station 402 and pat it neatly with the cylinder. The reciprocating swing mechanism 404 consists of a rotating mechanism and an L-shaped rotating frame. A first greaseproof paper suction mold 408 is provided at the front end of the L-shaped rotating frame, which switches back and forth between the sorting station 402 and the intermediate adhesive application platform 403. A second greaseproof paper suction mold 409 is provided at the right end of the L-shaped rotating frame, which switches back and forth between the intermediate adhesive application platform 403 and the greaseproof paper application station. At the same time, the inner application brush roller mechanism 406 is provided at the end of the second greaseproof paper suction mold 409. It includes a mounting base 4061 fixed at the end of the second greaseproof paper suction mold 409. A pressing cylinder 4062 is provided on the mounting base 4061. A third brush roller 4062 is connected to the lower end of the pressing cylinder 4062 to press the end of the greaseproof paper after adhesive application into the inner box end wall. Furthermore, in the specific design, both the first and second paper-absorbing molds 408 and 409 are composed of a cylinder and an adsorption mold. When the first paper-absorbing mold 408 is directly above the sorting station 402, the second paper-absorbing mold 409 is directly above the transfer adhesive-applying platform 403; when the first paper-absorbing mold 408 is directly above the transfer adhesive-applying platform 403, the second paper-absorbing mold 409 is directly above the paper-applying station. Additionally, a double-sided adhesive applicator 405 is provided at the lower end of the transfer adhesive-applying platform 403. The specific double-sided adhesive applicator 405 is existing technology, and its specific structure will not be described in detail in this embodiment 1. Finally, a workpiece positioning component (not shown in the figure) is also provided on the second conveying unit 600 of the paper-applying station.

[0038] In the specific operation of the linerboard applicator unit 400, after the box lid is opened and the inner mold is removed, the assembly enters the linerboard applicator station under the conveying of the second conveying unit 600, and the workpiece positioning component precisely positions and fixes the assembly. The suction cup gripping component 407 in the linerboard applicator unit 400 grabs the linerboard from the top layer of the linerboard hopper 401 and neatly places it into the sorting station 402. Then, the reciprocating swing mechanism 404 drives the first suction linerboard mold 408 to rotate to directly above the sorting station 402, grabs the linerboard from the sorting station 402, and places it on the transfer adhesive applicator platform 403, with one end of the linerboard extending a certain distance from the end of the transfer adhesive applicator platform 403. Then, the double-sided adhesive applicator mechanism 405 applies double-sided adhesive to the end of the linerboard extending from the transfer adhesive applicator platform 403. After the double-sided tape is applied, the greaseproof paper is picked up by the second greaseproof paper mold 409 and rotated to the top of the assembly after the box lid is opened and the inner mold is removed. Then, under the action of the inner brush roller mechanism 406, the end of the greaseproof paper with double-sided tape is attached to the inner wall of the inner box, thereby completing the adhesion between the greaseproof paper and the inner wall of the assembly, forming the final required packaging box.

[0039] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
