Description

Technical Field

[0001] The invention relates to the production of a surrounding frame, in particular to a production and forming device for a surrounding frame paper box. Background Art

[0002] For example, paper boxes such as wine boxes, drawer boxes, book boxes, and lids have a box body that is an enclosed frame structure, such as a square frame. When making this type of frame, the material (including cardboard and facial tissue) can be clasped on the upper (horizontal) mold, and then the final connection (such as overlap, i.e. upper side molding) is made on the upper side of the (horizontal) mold to achieve enclosure and form the frame. For example, the side molding mechanism of the CN104842588A paper box forming machine, the CN218286882U paper box forming equipment production line, the CN216330403U paper box forming clasping mechanism, the CN219968976U frame forming mechanism, etc. are used for the enclosed molding structure on the enclosed mold. Among them, the lower side of the cardboard in the material (corresponding to the outside of the box body) is pasted with facial paper, and the upper side of the cardboard (corresponding to the inside of the box body) is usually grooved to facilitate folding and enclosure. The cardboard forms a multi-layer cardboard with multiple areas, and the facial paper also has multiple areas corresponding to the cardboard. After enclosure, the paper is on the outside of the box body. For example, the cardboard has four areas (i.e., four-layer cardboard) corresponding to the four-square frame box body (corresponding to the four side walls of the frame box body), and the facial paper also has four areas corresponding to the cardboard, and is pasted on the lower side of the cardboard at an offset position; for example, the three areas on the right side of the cardboard are pasted corresponding to the three areas on the left side of the facial paper, the leftmost area of ​​the cardboard has not been pasted, and the rightmost area of ​​the facial paper has not been pasted. When enclosed, the facial paper in the rightmost area of ​​the facial paper can be pasted outside the leftmost area of ​​the cardboard to complete the paper pasting. The technology of enclosing the material with staggered cardboard and facial tissue to form a frame box body is mature. However, for relatively narrow and long strip materials, the long strip materials (long strip cardboard and facial tissue) are unstable when finally enclosed. (The rightmost area) The unmounted facial tissue is narrow and long during the folding and enclosing process, and is soft, which makes it easy for the facial tissue to be unstable, difficult to fold in place, and skewed. Moreover, (the rightmost area) The unmounted facial tissue needs to be mounted from the right to the left during the folding and enclosing process (and reset after mounting) so that it is completely mounted on the cardboard. For materials with longer sizes, the mounting efficiency is low. Summary of the invention

Detailed implementation manner

[0033] Referring to the attached drawings, in the embodiment of this implementation manner, the production line for forming a framed carton includes a box body face paper feeding device 71, a box body face paper gluing device 72, a material conveying device 57, a material laminating station 58, a three-sided edge wrapping station 60, and a framed carton forming main machine 73. The box body face paper feeding device 71 and the box body face paper gluing device 72 are connected by a paper feeding device 74. The face paper output end of the box body face paper gluing device 72 is connected to the material conveying device 57. The material laminating station 58 is connected with a material laminating device 59 for laminating the box body cardboard and face paper. The three-sided edge wrapping station 60 is connected with a flat cardboard three-sided face paper edge wrapping device 61 corresponding to the left, right, and lower three sides of the horizontal framed box body. The material laminating station 58 and the three-sided edge wrapping station 60, as well as the three-sided edge wrapping station 60 and the second mold stop position 2, are connected by the material conveying device 57. The material conveying device 57 transports the glued face paper to the material laminating station 58 (where the cardboard will be laminated on this face paper), and then the material conveying device 57 continues to transport the face paper and the laminated cardboard to the three-sided edge wrapping station 60 (for three-sided edge wrapping), and then continues to feed the materials into the framed carton forming main machine 73. Additionally, a material deviation correction and pressure application station 76 (to make the lamination more firm) can be set between the material laminating station 58 and the three-sided edge wrapping station 60. Even a magnet loading station can be set between the face paper gluing device and the material laminating station 58, and a corresponding magnet sheet assembling device 75 is provided, such as the magnet sheet or metal sheet assembling device of the shell production equipment of CN219504085U, so as to directly install magnetic patches on the glued face paper, making the produced framed carton have a magnetic attraction function. Even an oven station can be set. The oven is set between the face paper gluing device and the material laminating station 58. The glued face paper is transported by the material conveying device 57 and passes through the oven, which can make the glue act quickly. For example, the production line of the carton forming equipment of CN218286882U, the novel carton forming production line of CN216330338U, the carton forming production line of CN113650351A, the carton forming production line of CN215243189U, etc. are mature technologies. Among them, the box body face paper feeding device 71 includes a lifting paper feeding table 33, the paper feeding device 74 includes a feeder, the box body face paper gluing device 72 includes a gluing roller, the laminating cover device includes a cover manipulator, and the flat cardboard three-sided edge wrapping device includes an edge wrapping board; the material conveying device 57 includes a material conveyor belt 62 and a material input manipulator 63. The material conveyor belt 62 connects the material laminating station 58 and the three-sided edge wrapping station 60. The material conveyor belt 62 is arranged in front of the second mold stop position 2. The material input manipulator 63 is connected and configured between the material conveyor belt 62 and the second mold stop position 2; the demolding and box discharging device 40 is also connected with a box body transfer device, and the box body transfer device is connected with a carton bubble pressing machine. Even a box cover assembling machine, an inner tray assembling machine, a panel assembling machine, etc. can be connected later according to requirements.Among them, the mainframe 73 for forming the framed paper box adopts the following structure in this embodiment.

[0034] In this embodiment, the mainframe 73 for forming the framed paper box includes a four-station die rotating device. The four-station die rotating device includes a box body horizontal forming die 100 (four can be set) that intermittently rotates and stays around the vertical central axis. The box body of the framed paper box is formed by combining and connecting a framed box body 200 formed by enclosure and a box bottom plate 800, and is formed by cooperating with the box body horizontal forming die 100. The box body horizontal forming die 100 is composed of a number of templates combined and connected according to requirements. Among them, an outer end face 1001 (i.e., the front face) of the rotation circumference of the box body horizontal forming die 100 facing outward in the radial direction is provided with a box bottom plate suction and release nozzle 1002. Among them, the box body horizontal forming die 100 has a first die stay position 1, a second die stay position 2, a third die stay position 3, and a fourth die stay position 4. That is, during the process of the box body horizontal forming die 100 intermittently rotating and staying around the vertical central axis, it stays at the first die stay position 1, the second die stay position 2, the third die stay position 3, and the fourth die stay position 4 in sequence.

[0035] Among them, the first die stay position 1 is provided with a box bottom plate assembling device 10 for assembling the box bottom plate onto the outer end face 1001 of the box body horizontal forming die 100 staying at the first die stay position 1. The box bottom plate assembling device 10 is used to assemble the box bottom plate onto the outer end face 1001 of the box body horizontal forming die 100 staying at the first die stay position 1, and it can be sucked and held by the cooperation of the box bottom plate suction and release nozzle 1002. The structural form of the box bottom plate assembling device 10 is diverse and relatively mature. For example, the relevant upper bottom structures in the paper box forming equipment production line of CN218286882U and the paper box forming machine of CN104842586A.

[0036] Among them, the second die stay position 2 is provided with a framed box body clamping device 24 for the box body cardboard face paper laminating material enclosing die. The framed box body clamping device 24 is used to enclose the box body cardboard face paper laminating material (which can be simply referred to as the material) onto the box body horizontal forming die 100 (upper, lower, left, and right sides) staying at the second die stay position 2. The structural form of the framed box body clamping device 24 is diverse and relatively mature. For example, the side forming mechanisms in the paper box forming equipment production line of CN218286882U, the paper box forming machine of CN104842586A, the paper box forming machine of CN104842588A, the paper box forming clamping mechanism 23 of CN216330403U, the framed forming mechanism of CN219968976U, the side forming mechanism of a paper box forming machine of CN218257048U, etc.

[0037] Among them, the third die stop position 3 is equipped with a device 300 for pasting and laminating the cover paper on the outer wall surface of the upper side of the surrounding frame box body. The horizontal surrounding frame box body has been enclosed on the box body horizontal forming die 100 at the second die stop position 2, and is moved to the third die stop position 3 by the cooperation of the box body horizontal forming die 100. A complete surface paper 101 is separately pasted on the outer wall surface of the upper side of the horizontal surrounding frame box body 200 by the cooperation of the device 300 for pasting and laminating the cover paper on the outer wall surface of the upper side of the surrounding frame box body (completely covering). This not only provides a new manufacturing method, that is, pasting and laminating the cover paper by additionally supplementing the surface paper, to meet the requirements of different process manufacturing, but also is more stable and has relatively higher efficiency when pasting the cover. There is no need to paste this part of the surface paper on the outer wall surface of the upper side of the horizontal surrounding frame box body in advance, and the box body material does not need to have this part of the surface paper to form the surrounding frame box body, avoiding problems such as instability, skew, low quality, and low efficiency when the long strip-shaped surface paper is folded and enclosed on the outer wall surface of the upper side. It can even simplify the surrounding process of the surrounding frame box body in the prior process (i.e., the second die stop position 2), and the surface paper in the surface paper material of the box body cardboard of the surrounding frame box body does not need to be too long. Compared with the prior art, for example, in the CN104842586A carton forming machine, etc., for relatively narrow and long strip materials, the strip-shaped materials (strip-shaped cardboard and surface paper) are unstable when finally enclosed. The unpasted surface paper in the rightmost area is narrow and long and is soft, and it is easy to have problems such as unstable folding of the surface paper, difficult folding of the surface paper in place, and skew of the surface paper during the folding and enclosing process. Moreover, the unpasted surface paper in the rightmost area needs to be pasted from the right to the left (and reset after pasting) during the folding and enclosing process to completely paste it on the cardboard, resulting in low pasting efficiency for materials with a long size.

[0038] Among them, the fourth die stop position 4 is equipped with a demolding and box discharging device 40. The demolding and box discharging device 40 cooperates to demold and take out the surrounding frame carton formed by the host on the box body horizontal forming die 100 staying at the fourth die stop position 4, so that the surrounding frame carton is separated from the box body horizontal forming die 100. The demolding and box discharging device 40 is a mature technology, such as the box discharging mechanisms of the CN104842586A carton forming machine, the CN213261359U carton forming machine, and the CN219544134U box discharging mechanism of a carton forming machine, etc. The box can be moved out by clamping the box body on both sides or hooking the box mouth. After the box is discharged, a flipping mechanism or a baffle can be used to make the horizontal surrounding frame carton into a vertical surrounding frame carton for stable transportation. Then, a vertical bubble pressing machine (even with the function of hemming the fourth opening) can be used for the subsequent bubble pressing machine.

[0039] In the mainframe 73 for forming the framed carton, the device 300 for pasting the supplementary cover paper on the outer wall surface of the upper side of the framed carton body cooperates at the third die stop position 3 to paste a complete cover paper 101 (which can be called a single cover paper or a separate cover paper) onto the outer wall of the upper side of the horizontal framed carton body for covering the cover (complete coverage). This not only provides a new manufacturing method, that is, pasting the supplementary cover paper, to meet the requirements of different manufacturing processes, but also is more stable and has relatively higher efficiency when pasting the cover. There is no need to paste this part of the cover paper on the outer wall of the upper side of the horizontal framed carton body in advance, and the carton body material does not need to have this part of the cover paper to form the framed carton body, thus avoiding problems such as instability, skew, low quality, and low efficiency when the long strip of cover paper is folded and enclosed on the outer wall of the upper side. It can even simplify the enclosure process of the framed carton body in the prior process (i.e., the second die stop position 2), and the cover paper in the cover paper material of the carton body cardboard in the framed carton body does not need to be too long. Then, in cooperation with the corresponding operations at each stop position of the first die stop position 1, the second die stop position 2, the third die stop position 3, and the fourth die stop position 4, the forming operation of the framed carton in the mainframe is realized. The framed carton forming machine can adopt the following cover paper laminating materials for the carton body cardboard (i.e., the materials in this embodiment, or the carton body materials). Among them, the carton body cardboard (corresponding to the four side walls of the carton body) adopts a four - connected cardboard 102 (which can form a four - connected structure through slotting). There is no cover paper pasted on the lower part of the left - hand connected cardboard, and the lower parts of the right - hand three - connected cardboards are pasted on the cover paper. In addition, the right side of the cover paper also has a part that extends beyond the right - hand edge of the cardboard (i.e., the narrow flange strip of the cover paper), that is, the cover paper is a three - connected cover paper 103 corresponding to the carton body (the cover of three side walls).

[0040] Based on the above embodiments, the following optimizations or further explanations can be made respectively.

[0041] For example, the frame paper box forming main unit 73 also includes a folding paper pasting and bottom connecting device for connecting the box body face paper with the edge of the box bottom plate; wherein the box body face paper (including triple face paper and single face paper) also has a folding edge connecting bottom 106 for pasting on the box bottom plate. The folding paper pasting and connecting device cooperates to fold the folding edge of the box body face paper toward the four side positions (up, down, left, and right) of the box bottom plate (which has been installed on the outer end surface 1001 of the box body horizontal forming mold 100 at the first mold stop position 1). For example, the origami pasting bottom connecting device includes an origami pasting component 51 at the left edge of the box bottom plate, an origami pasting component 52 at the right edge of the box bottom plate, an origami pasting component 53 at the upper edge of the box bottom plate, and an origami pasting component 54 at the lower edge of the box bottom plate; for example, the origami pasting component 51 at the left edge of the box bottom plate and the origami pasting component 52 at the right edge of the box bottom plate are arranged at the second mold stop position 2, the origami pasting component 54 at the lower edge of the box bottom plate is arranged at the third mold stop position 3, and the origami pasting component 53 at the upper edge of the box bottom plate is arranged at the fourth mold stop position 4. Such a distribution arrangement is relatively more reasonable, can adapt to other molding operations at each stop position, and is more efficient. These origami pasting components can be operated by origami rollers, origami brushes, origami paper boards according to needs, and there are many structural methods; for example, the origami pasting component 51 on the left edge of the box bottom plate at the second mold stop position 2 and the origami pasting component 52 on the right edge of the box bottom plate respectively use origami paper boards that are driven by cylinders or motors to move left and right (or even diagonally forward and backward), and the origami pasting components at the third mold stop position 3 and the fourth mold stop position 4 respectively use origami rollers that are driven by cylinders 531, 541 or motors to move up and down.

[0042] In addition, a lower pressing plate 32 is provided below the third mold stop position 3, and the lower pressing plate 32 is transmission-connected to a lower pressing lifting drive component 321 (such as a cylinder or a motor, etc.); an upper pressing plate 55 is provided below the fourth mold stop position 4, and the upper pressing plate 55 is transmission-connected to an upper pressing lifting drive component 56 (such as a cylinder or a motor, etc.); the upper pressing plate 55 is lifted and lowered by the upper pressing lifting drive component 56, and cooperates with the horizontal box body forming mold 100 that applies pressure from above, and the lower pressing plate 32 is lifted and lowered by the lower pressing lifting drive component 321, and cooperates with the horizontal box body forming mold 100 that applies pressure from below, so as to press the horizontal box body forming mold 100 at the stable stop position, and can press the box body so that the edges in the corresponding directions can be stably folded and pasted.

[0043] In order to smoothly input (laminate the box body cardboard and the face paper) materials into the surrounding frame carton forming main machine 73, a material conveying device 57 can also be connected at the second die stop position 2. Among them, the material conveying device 57 is sequentially connected to the material laminating station 58, the three-side edge-wrapping station 60, and the second die stop position 2. At the material laminating station 58, the materials in this embodiment are laminated (the cardboard is laminated corresponding to the face paper that has been surface-glued). The three-side edge-wrapping station 60 is used to perform edge-wrapping on the box mouth positions of three side walls among the four side walls of the surrounding frame carton body (the left, right, and lower side walls of the box mouth in the horizontal state). The material conveying device 57 cooperates to move and convey the laminated materials from the material laminating station 58 to the three-side edge-wrapping station 60 (for three-side edge-wrapping), and then convey the materials that have completed three-side edge-wrapping from the three-side edge-wrapping station 60 to the second die stop position 2. There are many ways for the material conveying device 57, which can be formed separately or in combination by a material conveyor belt 62, a pneumatic nozzle manipulator, a moving pneumatic claw, etc. The cooperation structure of the material conveying device 57 at the material laminating station 58, the three-side edge-wrapping station 60, and the second die stop position 2 is also relatively mature. For example, the material conveying device 57 and its cooperation structure in the carton forming machine of CN104842586A, the carton forming equipment production line of CN218286882U, the carton forming equipment of CN221892651U, etc. In this embodiment, the surrounding frame carton forming main machine 73 can be configured with a fourth-side edge-wrapping mechanism to perform edge-wrapping on the fourth side of the box body, such as setting the third and fourth die stop positions 4. Of course, the fourth-side edge-wrapping can also be completed in the subsequent production line. Even the main machine can not perform box mouth edge-wrapping.

[0044] Among them, the material laminating station 58 is connected with a material laminating device 59 for laminating the box body cardboard and the face paper materials. The material laminating device 59 (or called a positioning machine or a cardboard covering mechanism, etc. is a mature technology) laminates the cardboard corresponding to the face paper that has been surface-glued.

[0045] Among them, the three-side edge-wrapping station 60 is connected with a flat cardboard three-side face paper edge-wrapping device 61 corresponding to the left, right, and lower three-side box mouths of the horizontal surrounding frame box body. The flat cardboard three-side face paper edge-wrapping device 61 cooperates to perform face paper edge-wrapping on the corresponding left, right, and lower three-side box mouths (that is, the right three joints of the cardboard) of the box body cardboard (quadruple cardboard). The flat cardboard three-side face paper edge-wrapping device 61 is a mature technology, which has an edge-wrapping board that can be lifted and horizontally moved. The lifting and horizontal movement can be respectively driven by a cylinder or a motor (such as a servo motor with a lead screw and nut mechanism).

[0046] It can be further explained that the material laminating device 59 includes a box body material laminating mechanism for laminating the flat four - joint cardboard of the box body and the facing paper that lacks (i.e., there is no) the corresponding cover on the outer wall paper area of the upper side of the horizontal frame box body. That is, in this embodiment, the box body material is formed by laminating the right three joints of the four - joint cardboard and the bottom (three - joint) facing paper correspondingly, where the (three - joint) facing paper lacks the corresponding cover on the outer wall paper area of the upper side of the horizontal frame box body, that is, there is no facing paper cover laminated under the left - hand joint of the four - joint cardboard. Among them, the facing paper that lacks the corresponding cover on the outer wall paper area of the upper side of the horizontal frame box body is the three - joint facing paper of the box body side wall. The left and right sides of the three - joint facing paper of the box body side wall respectively have facing paper flange narrow strips for lapping the box body cardboard. The facing paper flange narrow strips are not only used for lapping connection during enclosure but also can prevent the inner cardboard from being exposed at the edge after enclosure. In the material laminating device 59, the corresponding cardboard is laminated on the correspondingly surface - glued facing paper placed on the material conveyor belt. The tail ends of the three - joint facing paper of the box body side wall respectively have a folded edge connecting the bottom 106, and the tail end of the single facing paper in the supplementary paper pasting and cover laminating device 300 for the outer wall paper of the upper side of the frame box body also has a folded edge connecting the bottom 106; the head ends of the three - joint facing paper of the box body side wall have a box - mouth edge - wrapping part 107, and the head end of the single facing paper in the supplementary paper pasting and cover laminating device 300 for the outer wall paper of the upper side of the frame box body also has a box - mouth edge - wrapping part 107, so as to additionally realize box - mouth edge - wrapping in the main machine or production line. Of course, it can also be not used.

[0047] Therefore, the frame box body clamping device 24 uses the box body cardboard facing paper laminating material that lacks (i.e., there is no) the corresponding cover on the outer wall paper area of the upper side of the horizontal frame box body for die - enclosing the frame box body clamping device 24. Subsequently, at the third die stop position 3, the supplementary paper pasting and cover laminating device 300 for the outer wall paper of the upper side of the frame box body can supplement and paste the single facing paper 101 on the corresponding cover on the upper side outer wall of the horizontal frame box body 200.

[0048] In the embodiment of this embodiment, the supplementary paper pasting and cover laminating device 300 for the outer wall paper of the upper side of the horizontal frame box body has a supplementary upper - side facing paper pasting and cover laminating station; among them, the supplementary upper - side facing paper pasting and cover laminating station is arranged above the third die stop position 3 so as to perform the corresponding supplementary paper pasting and cover laminating of the facing paper 101 at the upper - side position. In addition, the supplementary paper pasting and cover laminating device 300 for the outer wall paper of the upper side of the horizontal frame box body also includes an upper - side facing paper feeding device 30 and a paper - picking, transferring and cover - laminating device 31. The upper side paper feeding device 30 supplies the upper side paper 101 for subsequent operations (such as the paper picking, transferring and pasting cover device 31). Among them, the upper side paper feeding device 30 is connected to the upper side paper supplementary sheet pasting cover station by the paper picking, transferring and pasting cover device 31. The paper picking, transferring and pasting cover device 31 picks up the upper side paper supplied by the upper side paper feeding device 30 and transfers it to the upper side paper supplementary sheet pasting cover station, and cooperates to paste the cover at the upper side paper supplementary sheet pasting cover station, so as to realize the supplementary sheet pasting of the face paper 101 on the upper outer wall of the horizontal frame box body 200.

[0049] The upper side outer wall face paper supplementary sheet pasting cover device 300 of the horizontal frame box body can separately paste a complete face paper on the upper side outer wall of the horizontal frame box body (completely covering the full width). This way of separately pasting a complete face paper not only provides a new matching method for frame production, but also is more stable and has relatively higher efficiency when pasting the cover. There is no need to paste the face paper of this part on the upper side outer wall of the horizontal frame box body in advance, and the box body material does not need to have the face paper of this part to form a frame box body, avoiding problems such as instability, skew, low quality and low efficiency when the long strip face paper is folded and enclosed on the upper side outer wall. It can even simplify the enclosure process of the frame box body in the prior process, and the face paper in the face paper material of the box body cardboard in the frame box body does not need to be too long.

[0050] For example, to make a horizontal frame box body, its four side walls of the box body are made by laminating the cardboard and the face paper 104. For example, the box body cardboard uses a four - joint cardboard 102 (which can form a four - joint structure through slotting). The lower part of the left joint of the cardboard is not pasted with the cover face paper, and the lower parts of the right three joints of the cardboard are pasted with the upper cover on the face paper. In addition, the right side of the face paper also has a part that extends beyond the right edge of the cardboard (that is, the face paper flange narrow strip 105), that is, the face paper is a three - joint face paper 103 corresponding to the box body (three - side wall cover). When connecting the upper side during the enclosure process of the horizontal frame box body, the box body horizontal forming die 100 has stopped at the second die stop position 2. The cardboard part (the left - most joint cardboard) in the material (including the pre - glued face paper and the cardboard pasted on it) has been turned to the upper side of the second die stop position 2 to cooperate with the enclosure die, that is, the cardboard part without pasting the cover in the material is folded to the upper side of the box body horizontal forming die 100. Based on the above embodiments, the following optimizations or further explanations can be made.

[0051] For example, a lower press plate 32 is provided on the lower side of the third die stop position 3. The lower press plate 32 is drivingly connected to a lower press lifting drive member 321 (such as including a cylinder or a motor, etc.). The lower press lifting drive member 321 cooperates to drive the lower press plate 32 to lift and lower, and can cooperate to press the die (i.e., the box body horizontal forming die 100) that runs and stops at the third die stop position 3 below. That is, the lower press plate 32 can apply pressure to the die in cooperation from below. When the paper picking, transferring and pasting cover device 31 applies pressure to paste the cover above the third die stop position 3, it is more stable, the die is more balanced in force up and down, and the effect of pasting the cover is also better.

[0052] For instance, the upper side paper feeding device 30 includes a feeding table 301. The feeding table 301 is arranged on the front side of the third die stop position 3 (that is, one side facing the position of the box body and box bottom plate at the third die stop position 3, that is, the front side), and single sheet of side paper is provided by the feeding table 301 for feeding.

[0053] For example, the paper picking, transferring and pasting cover device 31 includes a face paper sucking, releasing and pressing plate 311. The face paper sucking, releasing and pressing plate 311 is provided with a sucking, releasing and paper picking air nozzle part 3111. The sucking, releasing and paper picking air nozzle part 3111 is arranged downward. When the sucking, releasing and paper picking air nozzle part 3111 cooperates with negative pressure suction, it sucks the face paper, and when it does not suck air (such as when the air is cut off or communicated with the atmosphere), it releases the face paper. Among them, the moving track mode of the face paper sucking, releasing and pressing plate 311 is more (such as lifting, rotating, translating, etc.); in this embodiment, a relatively simple and stable operation mode will be adopted, that is, when the face paper sucking, releasing and pressing plate 311 runs, it performs lifting and translation cooperation actions. Among them, the face paper sucking, releasing and pressing plate 311 is drivingly connected to a paper picking, pasting, lifting and translating drive member 312, that is, the paper picking, pasting, lifting and translating drive member 312 (such as including a motor or a cylinder, etc.) cooperates to drive the face paper sucking, releasing and pressing plate 311 to perform corresponding lifting and translation.

[0054] Among them, the feed table 301 is further optimized, and a single sheet of facial paper is placed on the feed table 301 and supported by the supporting plane 302, and the sheet of facial paper is in a flat state; the feed table 301 is also equipped with a facial paper positioning and correction mechanism 303, which can position and correct the single sheet of facial paper on the feed table 301 to ensure the accuracy of the relative position when the cover is subsequently mounted. For example, the facial paper positioning and correction mechanism 303 includes a side push gauge 304, and the side push gauge 304 is connected to a correction drive component 305 (such as a cylinder or a motor), and the correction drive component 305 drives the side push gauge 304 to move back and forth to cooperate with positioning, correction and return. The layout of the side push gauge 304 can be set according to demand, for example, the side push gauge 304 is respectively configured on the left and right sides and the front side of the feed table 301 (its supporting plane 302), and the rear side can be fixed with a limit stop 306. There are many layout settings and they are not repeated. In addition, a lifting paper supply platform 33 is provided next to the feeding platform 301. The lifting paper supply platform 33 has many structural modes and is relatively mature. For example, the lifting paper supply platform 33 includes a lifting feeding paper support frame 331. The lifting feeding paper support frame 331 is connected to the lifting feeding drive motor 332 by transmission. The lifting feeding drive motor 332 (such as a servo motor, etc.) cooperates to drive the lifting feeding paper support frame 331 of the lifting paper supply platform 33 to rise and fall, and the facial papers stacked on it are gradually supplied upward during the rising process; a facial paper input and transfer mechanism 34 is connected between the lifting paper supply platform 33 and the feeding platform 301, and the facial paper input and transfer mechanism 34 can input and transfer the facial papers (such as the top layer of the stacked facial papers) supplied upward by the lifting paper supply platform 33 one by one to the feeding platform 301 (such as its support plate). There are many types of tissue paper input and transfer mechanisms 34, such as tissue paper input and transfer by a feeder paper feeding structure, etc.; for another example, the tissue paper input and transfer mechanism 34 includes a lifting and translational suction and release nozzle 341 (which sucks tissue paper when negative pressure occurs and releases tissue paper when negative pressure is released), the lifting and translational suction and release nozzle 341 is transmission-connected to a feed lifting and translational driving component 342, and the feed lifting and translational driving component 342 cooperates to drive the lifting and translational suction and release nozzle 341 to lift and translate. During operation, the lifting and translational suction and release nozzle 341 descends to suck tissue paper on the lifting paper feeding table 33 (the top layer of the stack), and then the lifting and translational suction and release nozzle 341 rises to lift the tissue paper, and then translates and transfers the tissue paper to the feeding table 301, directly releases it or releases it to the feeding table 301 after descending, and finally the lifting and translational suction and release nozzle 341 returns to its original position and waits for the next work. The feed lifting and translation driving component 342 may include a translation driving cylinder 343 and a lifting driving cylinder 344, and may be configured with corresponding translation and lifting tracks for stable operation. In the figure, the translation driving cylinder 343 drives the translation slide 345 to translate back and forth, and the lifting driving cylinder 344 drives the lifting and translation suction and release nozzle 341 installed on the translation slide 345 to perform lifting and lowering movements.Among them, a paper-taking and laminating pressing plane is provided on the lower side of the facial tissue suction and release pressing plate 311. When taking the paper for laminating the cover and applying pressure, it is relatively more stable, ensuring that the facial tissue is relatively flat. The suction and release paper-taking air nozzle part 3111 can adopt air holes distributed on the paper-taking and laminating pressing plane, which is relatively convenient for processing. For example, the paper-taking, laminating, lifting, and translation driving component 312 can include a paper-taking, laminating, lifting driving motor 3121 (such as a servo motor) and a paper-taking, laminating, translation driving motor 3122 (such as a servo motor). The paper-taking, laminating, translation driving motor 3122 (through a belt drive structure) cooperates to drive the translation plate 3123 to move horizontally relatively precisely, stably, and with adjustable and controllable translation. The paper-taking, laminating, lifting driving motor 3121 (through a lead screw and nut drive structure) cooperates to drive the facial tissue suction and release pressing plate 311 to lift on the translation plate 3123 relatively precisely, stably, and with adjustable and controllable translation. Corresponding tracks 310 can be configured for stable operation. In the figure, the paper-taking, laminating, lifting driving motor 3121 drives the lifting plate 3124 to lift on the translation plate 3123 through the lead screw and nut mechanism 313 (the nut is installed on the lifting plate 3124). The lifting plate 3124 is connected to the lower support plate 3126 through the connecting sleeve 3125. The lead screw can pass through the connecting sleeve 3125. An installation plate 3127 is arranged below the support plate 3126. A buffer spring 3128 is arranged between the support plate 3126 and the installation plate 3127, which can play a buffering effect when pressing down, adapt to the deviation of the facial tissue thickness, and be relatively more precise when taking the paper and laminating the cover. Guide rods 3129 can be arranged between the support plate 3126 and the installation plate 3127, and the spring is sleeved on the guide rods 3129. In addition, adjusting nuts are configured at the upper ends of the guide rods 3129 to adjust the compression amount of the buffer spring 3128, and then the facial tissue suction and release pressing plate 311 is assembled on the installation plate 3127. An air path (such as an air groove, an air chamber, etc.) can be arranged inside the facial tissue suction and release pressing plate 311, and the facial tissue suction and release pressing plate 311 can be divided into an upper layer plate and a lower layer plate combined structure, which is convenient for processing and setting the internal air path.

[0055] The paper patching and pasting cover device 300 on the upper outer wall surface of the horizontal enclosure box body further includes an upper gluing mechanism 35 on the lower side of the face paper. The upper gluing mechanism 35 on the lower side of the face paper is arranged below the paper picking, transferring and pasting cover device 31. The upper gluing mechanism 35 on the lower side of the face paper cooperates with the lower side of the face paper for patching and pasting the cover, directly gluing the face paper, making the structure relatively reasonable and compact. There is no need to pre-glue the upper outer wall of the horizontal enclosure box body to be pasted with the cover (such as gluing by spraying or other methods). It can complete the gluing on the lower layer (surface) of the face paper during the paper picking, transferring and pasting process of the paper picking, transferring and pasting cover device 31, which is more convenient and practical. Among them, the upper gluing mechanism 35 on the lower side of the face paper is arranged below the paper picking, transferring and pasting cover device 31, which can cooperate efficiently and can cooperate with the paper picking, transferring and pasting cover device 31 for gluing during the paper picking and transferring process. For example, the upper gluing mechanism 35 on the lower side of the face paper is arranged between the upper side face paper feeding device 30 and the third mold stop position 3, the structure is more compact, and the paper picking and transferring path of the paper picking, transferring and pasting cover device 31 is more reasonable. There are many gluing methods for the upper gluing mechanism 35 on the lower side of the face paper, such as spraying, roller coating, brush coating and other gluing methods. In this embodiment, the upper gluing mechanism 35 on the lower side of the face paper includes a glue coating roller 351. The glue coating roller 351 is arranged below the transfer path of the paper picking, transferring and pasting cover device 31 (the face paper suction and release pressing plate 311), and uses the rotation of the glue coating roller 351 to cooperate with efficient roller coating. For example, the face paper suction and release pressing plate 311 translates and transfers the face paper through the upper part of the glue coating roller 351, and cooperates with contact for gluing. Among them, the gluing method of the glue coating roller 351 is relatively mature. For example, a glue feeding roller 352 is arranged below the glue coating roller 351, and a glue storage box 353 is arranged under the glue feeding roller 352. The glue feeding roller 352 rotates to transfer the glue in the glue storage box 353 to the glue coating roller 351 and makes the glue layer on the glue coating roller 351 relatively uniform. The glue coating roller 351 and the glue feeding roller 352 can use the same glue coating motor 354 and be driven by gear 359 meshing (gear meshing has a gap), and the pressure between the glue feeding roller 352 and the glue coating roller 351 can also be adjusted, so as to adjust the glue thickness. For example, the bearing seats at both ends of the glue feeding roller 352 are connected with adjusting screw rods 355. In addition, the glue storage box 353 can be inserted and arranged in the lifting support partition bin 356 (which can be lifted and switched states with a partition cylinder 358). After the lifting support partition bin 356 descends, the glue storage box 353 can be moved out to the auxiliary support plate 357 for cleaning, replacement and other operations. When in use, the glue storage box 353 is pushed into the lifting support partition bin 356 from the auxiliary support plate 357, and the lifting support partition bin 356 rises again to move the glue storage box 353 into place, so that the glue feeding roller 352 can transfer the glue in the glue storage box 353. Among them, the third mold stop position 3 is for the box body horizontal forming mold 100 to stay during operation. For example, the third mold stop position 3 is equipped with a box body horizontal forming mold 100 that intermittently rotates and stays around the vertical central axis, so that the box body horizontal forming mold 100 can perform other operations at other stop positions during the intermittent rotation and stay process, such as enclosing the horizontal enclosure box body on the mold at the previous position.

[0056] In addition, the front of the third mold stop position 3 is also provided with a heating device 90, which may include a heating shell, in which an electric hot air or a drying lamp or a heating tube or a combination thereof may be arranged as a heat source, and the heating device may heat the upper surface paper of the replacement cover, so that the glue on it can take effect as soon as possible so as to quickly and firmly adhere, and in particular, the folded edge and the bottom of the tail end of the surface paper (i.e., the separate surface paper) of the replacement cover are heated, which helps it (the folded edge and the bottom, which have a relatively small area) to quickly play a role in bonding the bottom plate of the box in the subsequent (such as the next mold stop position); the heating device 90 faces the upper side of the third mold stop position 3, and the height position (such as lifting the heating shell) and the angle position (such as rotating the heating shell) of the heating device (90) are adjusted and set.

[0057] In an embodiment of the present embodiment, a horizontal frame box body enclosing and molding device includes an upper connecting mechanism 20, which is arranged on the upper side of the second mold stop position 2, and the second mold stop position 2 is for the box body horizontal molding mold 100 to stay here to cooperate with the frame box body enclosing and molding, and the upper connecting mechanism 20 (arranged on the upper side of the second mold stop position 2) is used to cooperate with the upper side connection of the frame box body; wherein, the upper connecting mechanism 20 includes a downward pressing plate 21 and a transverse edge paper lapping component 22, the downward pressing plate 21 is connected to a pressing lifting driving component 211 (such as a motor or a cylinder, etc.), and the pressing lifting driving component 211 cooperates to drive the downward pressing plate 21 to move up and down, and the transverse edge paper lapping component 22 is connected to a first transverse driving component 221 (such as a motor or a cylinder, etc.), and the first transverse driving component 221 cooperates to drive the transverse edge paper lapping component 22 (left and right) to move horizontally to perform edge paper lapping.

[0058] For example, a horizontal frame box body is made, which is enclosed by a combination of cardboard and facial paper to form the four side walls of the box body. For example, the box body cardboard adopts a four-piece cardboard (a four-piece structure can be formed by slotting), the left side of the cardboard has no cover facial paper mounted on the bottom, and the right three pieces of the cardboard are mounted on the facial paper cover. In addition, the right side of the facial paper also has a portion that exceeds the right edge of the cardboard (i.e., the facial paper flange narrow edge strip), that is, the facial paper is a three-piece facial paper corresponding to the box body (three side wall cover). During the enclosing process of the horizontal frame box body, when the upper side is connected, the box body horizontal forming mold 100 has stopped at the second mold stop position 2, and the cardboard part (the leftmost piece of cardboard) in the material (including the pre-glued facial paper and the cardboard mounted thereon) has been turned to the upper side of the second mold stop position 2 to cooperate with the enclosing mold, that is, the cardboard part of the material without the cover mounted is folded to the upper side of the box body horizontal forming mold 100; At this time, the upper connecting mechanism 20 starts to work. The downward moving pressure plate 21 descends and cooperates to press the cardboard part on the upper side of the lower second die staying position 2 (the cardboard part at the leftmost side of the material, which is the cardboard of the leftmost sheet of the material at this time when staying at the horizontal box body forming die 100 here), so that the relative position of the cardboard part is in place and stable without displacement (ensuring firm and stable subsequent lap joint). Then, the transverse edge pasting and lapping component 22 makes a transverse movement, and cooperates to paste the face paper part (the face paper flange narrow strip of the material) that is higher and exceeds (the horizontal box body forming die 100) on the right side of the second die staying position 2 (the horizontal box body forming die 100 staying here at this time) on the right edge of the upper cardboard part (the cardboard of the leftmost sheet of the material). This face paper part (the face paper flange narrow strip of the material) is folded to the outside of the right edge of the upper cardboard part of the second die staying position 2 (the horizontal box body forming die 100 staying here at this time), realizing the lap joint of the face paper and the cardboard, and realizing that the face paper part on the right side is folded to the upper cardboard part and pasted and lapped, completing the upper side connection during the enclosure of the horizontal box body. Only a transverse movement is required to complete the pasting and lapping of the face paper flange narrow strip, and the transverse movement stroke is relatively short, which is more efficient. After that, the downward moving pressure plate 21 (rises) and the transverse edge pasting and lapping component 22 (moves horizontally to the right) retract and reset to wait for the next operation.

[0059] This horizontal box body enclosure forming device can meet the production of the upper side connection of the new type of horizontal box body, is more stable, more efficient, and has simple actions.

[0060] Based on the above embodiments respectively, the following optimizations or further explanations can be made.

[0061] For example, cardboard guiding and alignment correcting components 212 are respectively connected and arranged in front of and behind the downward moving pressure plate 21. The cardboard guiding and alignment correcting components 212 are a cardboard centering area for each other. During the process of the downward moving pressure plate 21 descending, the cardboard guiding and alignment correcting components 212 in front of and behind the downward moving pressure plate 21 cooperate to guide, center, and correct the cardboard part on the upper side of the second die staying position 2 (the horizontal box body forming die 100 staying here at this time) (the cardboard of the leftmost sheet of the material), so that the relative position of this cardboard part does not deviate. Among them, the opposite sides (i.e., the front and back facing sides) of the cardboard guiding and alignment correcting components 212 are set as guiding and alignment correcting surfaces (such as inclined surfaces, etc.). The front and / or rear positions of the cardboard guiding and alignment correcting components 212 on the downward moving pressure plate 21 are adjusted and installed, such as adjusting and installing by disassembling and assembling fasteners. After adjusting the front and rear positions, it can meet cardboard of different size specifications, which is more practical.

[0062] For another example, the first transverse moving frame 222 is in transmission connection with the first transverse moving driving component 221. Driven by the first transverse moving driving component 221, the first transverse moving frame 222 moves horizontally left and right (i.e., transverse movement). The transverse edge paper laminating and overlapping component 22 is installed on the first transverse moving frame 222 and moves horizontally together with the first transverse moving frame 222. The second transverse moving frame 215 is in transmission connection with the second transverse moving driving component 214 (such as including a motor or a cylinder, etc.). Driven by the second transverse moving driving component 214, the second transverse moving frame 215 moves horizontally left and right (i.e., transverse movement). The downward moving pressing plate 21 and the pressing lifting driving component 211 are installed on the second transverse moving frame 215. The downward moving pressing plate 21 and the pressing lifting driving component 211 move horizontally together with the second transverse moving frame 215, so that the downward moving pressing plate 21 can also perform additional transverse movement. This can not only be used to adjust the horizontal position to meet the requirements of the surrounding frame size specification, but also increase the movement freedom during operation by transverse movement. Even through transverse movement avoidance, after the cardboard part (the leftmost cardboard of the material) is more smoothly flipped to the upper side of the second mold stop position 2 (where the box body horizontal forming mold 100 stays at this time), and then moves back horizontally for downward pressing. The transverse movement can make the lifting stroke of the downward moving pressing plate 21 smaller. In the figure, the first transverse moving driving component 221 and the second transverse moving driving component 214 respectively use motors to drive the transverse movement through a belt drive method.

[0063] Among them, the pressing lifting driving component 211 is in transmission connection with a pressing lifting seat 213. The downward moving pressing plate 21 is installed on the pressing lifting seat 213 and is installed on the pressing lifting seat 213 in an adjustable height position, so as to ensure smooth operation and meet the requirements of the surrounding frame size specification through lifting debugging and installation. For example, it is installed and disassembled by using fasteners and vertical installation holes, etc. Similarly, the transverse edge paper laminating and overlapping component 22 is installed on the first transverse moving frame 222 in an adjustable height position.

[0064] In addition, the horizontal surrounding frame box body surrounding and forming device further includes a clamping mechanism 23. The clamping mechanism 23 includes a lifting top plate 231 arranged below the second mold stop position 2 and side folding clamping and flipping plates 232 arranged on the left and right sides of the second mold stop position 2. The clamping mechanism 23 is a mature technology. For example, the side forming mechanism of the carton forming machine in CN104842588A, the carton forming equipment production line in CN218286882U, the carton forming clamping mechanism 23 in CN216330403U, the surrounding frame forming mechanism in CN219968976U, etc.

[0065] In the figure, the clamping mechanism 23 is driven by a clamping main motor. The synchronous spline shaft drives the conjugate cam through the helical gear steering transmission pair, and the two linkages respectively drive the lifting top plate 231 to lift and the side-fold clamping and flipping plate 232 to flip (two groups are arranged on the left and right). The synchronous spline shaft also drives the intermediate cam to swing, and through the linkage, drives the lifting top plate 231 to lift, forming three groups of left, middle, and right lifting top plates 231 to match the requirements of the surrounding frame. The left bracket and the right bracket can be adjusted in the left and right positions respectively to meet the requirements of changes in the surrounding frame size specifications. The left side-fold clamping and flipping plate 232 and the lifting top plate 231 are arranged on the left bracket, and the right side-fold clamping and flipping plate 232 and the lifting top plate are arranged on the right bracket. The left bracket and the right bracket are respectively provided with corresponding helical gear steering transmission pairs, conjugate cams, and two linkages.

[0066] For further optimization, the side folding and clamping turning plate 232 on each side includes a turning plate body (with a corresponding turning shaft 234 for supporting its turning action). The turning plate body includes a main plate 2321 and an extended auxiliary plate 2322. The extended auxiliary plate 2322 is connected to the main plate 2321. The main plate 2321 is located at the turning root position relative to the extended auxiliary plate 2322 (i.e., relatively close to the line of the turning shaft 234). The extended auxiliary plate 2322 is set for extended or retracted adjustment relative to the extension of the main plate 2321. The combined structure of the main plate 2321 and the extended auxiliary plate 2322 can form different effective turning areas through adjustment, making the turning more stable. At the root position, it can effectively turn and press on both sides of the horizontal forming die 100 of the box body, and the turning and folding effects of the cardboard on both sides are better. In addition, the side folding and clamping turning plate 232 also includes a detachable additional extension strip 2323. The detachable additional extension strip 2323 is connected and installed on the turning plate body. By replacing and disassembling the additional extension strip 2323, additional extension strips 2323 of different lengths can be used to match enclosing frame paper boxes of different size specifications, and the overall weight of the side folding and clamping turning plate 232 is relatively low and the operation is relatively stable. Among them, the extended auxiliary plate 2322 is set for sliding distance adjustment relative to the main plate 2321, such as the sliding distance adjustment setting method of a sliding groove, to achieve extended or retracted adjustment setting. In addition, a width adjustment mounting seat 2324 is provided on the turning plate body, and the additional extension strip 2323 is arranged on the width adjustment mounting seat 2324 to adjust the width position of the additional extension strip 2323 before and after the turning plate body, corresponding to meeting the different specification requirements of the box height of the horizontal enclosing frame box body, making the turning more stable; the width adjustment mounting seat 2324 can be connected and set on the width adjustment sliding groove 2325 of the extended auxiliary plate 2322. Of course, among them, there is also an additional extension strip 2323 fixedly installed in a relative position on the turning plate body. Usually, the additional extension strip 2323 fixedly installed in a relative position is located at the corresponding edge position facing forward of the enclosing frame box body (i.e., the side with the die facing outward) to make the connection of the covering paper on the edge of the box bottom plate more stable in the future. A box mouth limit plate can also be provided on the side folding and clamping turning plate 232. When the material is put in, it can be limited so that the relative position of the material is accurate, and it also helps the material not to deviate from its position easily when it is turned onto the die (left and right sides).

[0067] When the embracing mechanism 23 is embracing, taking the material (the bonding of cardboard and face paper) in this embodiment as an example, the second cardboard on the right is pushed upward to the bottom side of the box body horizontal forming mold 100 by the lifting top plate 231, and the side folding embracing flip plates 232 on the left and right sides flip the second cardboard on the left and the rightmost cardboard to the left and right sides of the second mold stop position 2 (which is now stopped at the box body horizontal forming mold 100). During the flipping process, the side folding embracing flip plate 232 on the left will also flip the first cardboard on the left (i.e. the leftmost cardboard) together, and use inertia to flip and fold the leftmost cardboard to the upper side of the second mold stop position 2 (which is now stopped at the box body horizontal forming mold 100).

[0068] In order to make the first cardboard on the left turn over and fold toward the upper side of the second mold stop position 2 (where the box body horizontal forming mold 100 is stopped at this time) more smoothly, further optimization is performed, and an upper cardboard folding auxiliary block 2326 is also provided on the side folding and embracing flipping plate 232 on the left. When the side folding and embracing flipping plate 232 on the left is turned into place, the leftmost cardboard is folded and turned toward the upper side of the second mold stop position 2 (where the box body horizontal forming mold 100 is stopped at this time) by inertia, and the upper cardboard folding auxiliary block 2326 can also be used to smoothly press and fold the leftmost cardboard toward the second mold stop position 2 The upper side of the mold stop position 2 (where the box body horizontal forming mold 100 is stopped at this time); for example, an upper cardboard folding corner is left between the upper cardboard folding auxiliary block 2326 and the side folding and embracing flip plate 232 on the left, and the upper cardboard folding corner can cover the upper (left) corner position of the second mold stop position 2 (where the box body horizontal forming mold 100 is stopped at this time), so as to cooperate with the folding of the upper cardboard; in addition, the upper cardboard folding auxiliary block 2326 is adjusted relative to the folding radius position on the side folding and embracing flip plate 232, so as to meet the requirements of frame boxes of different specifications and sizes after adjustment. In addition to the above methods, a movable upper cardboard folding auxiliary block (not shown in the figure) can also be used. An upper cardboard folding auxiliary block is also provided on the side folding, embracing and flipping plate on the left. The upper cardboard folding auxiliary block is also equipped with a pressure power source for assisting the top surface of the pressing mold on the side folding, embracing and flipping plate. The pressure power source cooperates to drive the side folding, embracing and flipping plate to apply additional pressure and return. When the cardboard (the one on the left) is folded by the side folding, embracing and flipping plate 232 to the upper side of the third mold stop position 2 (at this time it stays at this place of the box body horizontal forming mold 100), the upper cardboard folding auxiliary block can also assist in applying additional pressure to the cardboard to ensure that it is folded in place; for example, the pressure power source uses a pressure cylinder, and the pressure cylinder is transmission-connected to the upper cardboard folding auxiliary block.

[0069] Supplementary description: The second die stop position 2 is equipped with a horizontal box forming die 100 that intermittently rotates and stops around the vertical central axis; the front side, or the left side, or the right side between the second die stop position 2 and the lifting top plate 231 is the material input side, so that the cardboard and the face paper laminating material are input for subsequent enclosure die operations by the horizontal frame box body enclosure forming device. There are many ways to input materials. It can be directly input by a conveyor belt, or by a pneumatic nozzle (i.e., the material input manipulator 63) that moves up and down and horizontally, or by a robot with a suction nozzle (including a multi-axis robotic arm) for cooperation. In addition, the top surface of the horizontal box forming die 100 is also equipped with a box mouth limiting step (not shown in the figure). For example, the box mouth limiting step is formed by setting a laminate, which can limit the cardboard on the top surface and prevent the cardboard enclosed on it from moving and shifting towards the box mouth (vertical central axis) direction.

[0070] In the production of frame carton forming, the forming process of the frame box body is that the frame box body is formed by enclosing the box body material on the horizontal box forming die. The box body material is a four - ply cardboard and a three - ply face paper laminating material. Among them, the right - most ply of the four - ply cardboard is not laminated by the three - ply face paper. After the box body material is enclosed into the frame box body, an additional single face paper (i.e., the supplementary face paper) is pasted on the outer wall of the upper side of the frame box body to complete the forming of the frame box body. Among them, the single face paper can be sucked and pasted on the outer wall of the upper side of the frame box body by the face paper suction and pressing plate (the lower side is the paper - picking laminating plane), which is flatter and more fitting. It is made of two face papers, namely the three - ply face paper and the single face paper, which avoids the excessive length of the box body material and also avoids problems caused by the lack of cardboard lamination support for the face paper folding and laminating. Moreover, the supplementary lamination of the single face paper on the cover can completely cover the outer wall of the upper side, avoiding the unsightly exposure of the overlapping part.
