Description

Technical Field

[0001] This invention relates to the technical field of packaging, and in particular to a short-side folding and bonding device for cardboard. Background Technology

[0002] Glass needs protection before transportation, such as using cardboard boxes for outer protection. To improve protection, packaging one glass piece per cardboard box is preferable. Existing glass packaging equipment involves opening externally purchased cardboard boxes, placing the glass inside, and then gluing the edges of the boxes together. However, this method is difficult for larger pieces of glass. Therefore, the cardboard box can be made of a bottom cardboard and a top cardboard. Specifically, the top cardboard is placed on top of the bottom cardboard (which forms the inner cavity for the glass), and the edges of the top cardboard are folded along the pre-folded lines towards the bottom cardboard and glued together. This completes the bonding between the top and bottom cardboard. A folding and gluing device suitable for protective cardboard boxes made of bottom and top cardboard needs to be developed to facilitate glass placement and glue the short edges of the top cardboard to the bottom cardboard.

Detailed Implementation

[0020] This invention provides a short-side folding and bonding device for face paper. To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the scope of protection of the invention.

[0021] This embodiment uses a rectangular bottom paperboard and top paperboard 20 for illustration. Correspondingly, the X-axis direction is the short side direction and the Y-axis direction is the long side direction.

[0022] Please see Figure 1 and Figure 2This invention provides a short-side folding and bonding device for face paperboard, comprising a frame 1, two conveying mechanisms 2, a long-side blocking mechanism 3, two short-side positioning mechanisms 4, two gluing mechanisms 5, a face paperboard feeding mechanism 6, and two folding mechanisms 7, all mounted on the frame 1. The conveying mechanisms 2 are used to convey the formed bottom paperboard downstream. The long-side blocking mechanism 3 is located downstream of the conveying mechanism 2 and is used to contact the downstream long side of the formed bottom paperboard. One of the short-side positioning mechanisms 4 is connected to a Y-axis drive mechanism, which drives the connected short-side positioning mechanism 4 and the short-side positioning mechanism... The gluing mechanism 5 and the conveying mechanism 2 on the same side move toward the other short side positioning mechanism 4, and the two short side positioning mechanisms 4 respectively contact the corresponding short side of the formed bottom paperboard; the two gluing mechanisms 5 are used to apply glue to the side wall of the corresponding short side of the formed bottom paperboard when they reciprocate along the X-axis; the face paperboard feeding mechanism 6 is used to move the face paperboard 20 to the upper part of the formed bottom paperboard when it reciprocates along the X-axis; the two folding mechanisms 7 are used to fold the short side of the face paperboard 20 toward the bottom paperboard, and make the folded edge formed by the face paperboard 20 bond with the glue on the side wall of the short side of the bottom paperboard.

[0023] In practical applications, the formed bottom paperboard is conveyed from upstream to the short-side folding station of the top paperboard located downstream. Guided by the conveying mechanism 2, the bottom paperboard continues to move downstream until its long side downstream / front contacts the long-side retaining mechanism 3. The long-side retaining mechanism 3 positions the bottom paperboard, ensuring it is against the edge and that the bottom and top paperboards are conveyed to the correct positions. This prevents the bottom paperboard from being incorrectly positioned when the top and bottom paperboards are closed, thus reducing the production of defective products. Next, the two short-side positioning mechanisms 4 move upward synchronously. Then, under the action of the Y-axis drive mechanism, one side of the short-side positioning mechanism 4, the gluing mechanism 5, and the conveying mechanism 2 move synchronously towards the other side of the short-side positioning mechanism 4 (Y-axis direction) until the short-side positioning mechanisms 4 on both sides abut against the side walls of the short sides of the bottom paperboard. The short-side positioning mechanisms 4 achieve the correct alignment of the short sides of the bottom paperboard. The positioning mechanism, in conjunction with the aforementioned long-side blocking mechanism 3, ensures the correct placement of the bottom cardboard. Subsequently, the top cardboard feeding mechanism 6 moves along the X-axis / upstream and places the top cardboard 20 onto the bottom cardboard. Then, the top cardboard feeding mechanism 6 resets along the X-axis / downstream. The long-side blocking mechanism 3 and the short-side positioning mechanism 4 reset downwards. Next, under the action of the two gluing mechanisms 5, glue is applied to the sidewalls of the short sides of the bottom cardboard. Then, under the action of the two folding mechanisms 7, the edges of the short sides of the top cardboard 20 are folded downwards and come into contact with the glue on the sidewalls of the short sides of the bottom cardboard. The folding mechanisms 7 remain operational, meaning that under external force, the folded edges of the top cardboard 20 remain in contact with the short sides of the top cardboard 20 for a period of time to ensure effective glue adhesion. Finally, all mechanisms reset, and under the action of the conveying mechanism 2, the glued carton is conveyed downstream, awaiting the next bottom cardboard to enter the top cardboard short-side folding station.

[0024] In some embodiments, a Y-axis slide rail 11 is provided on the frame 1, and a Y-axis slider 12 is slidably disposed on the Y-axis slide rail 11. The Y-axis slider 12 is connected to a sliding frame 13. The Y-axis drive mechanism is used to drive the sliding frame 13 to reciprocate along the Y-axis direction. The short side positioning mechanism 4 connected to the Y-axis drive mechanism, the gluing mechanism 5 on the same side as the short side positioning mechanism 4, and the conveying mechanism 2 are all located on the sliding frame 13. The two conveying mechanisms 2 are symmetrically arranged along the X-axis direction of the frame 1, and each conveying mechanism 2 includes multiple rotatable rotating rollers 21 and a conveying drive component for driving the multiple rotating rollers 21 to rotate synchronously. The multiple rotating rollers 21 located on the same side are spaced apart, and the multiple rotating rollers 21 are evenly distributed along the X-axis direction. To ensure the short sides of the bottom cardboard align correctly and that the feeding position of each bottom cardboard aligns with the feeding position of the top cardboard 20, a sliding frame 13 is provided. The corresponding short side aligning mechanism 4, conveying mechanism 2, gluing mechanism 5, and folding mechanism 7 are mounted on the sliding frame 13, allowing the mechanism on one side to drive the bottom cardboard synchronously towards the mechanism on the other side. Specifically, the conveying drive can consist of a motor, sprocket, chain, or a motor, drive wheel, and synchronous belt, etc., to make multiple rotating rollers 21 rotate synchronously to transport the bottom cardboard. The conveying drive is a conventional setup and will not be described in detail.

[0025] In some embodiments, the short-side positioning mechanism 4 includes a positioning cylinder 41 with its output end facing upward, a positioning connecting plate 42 connected to the output end of the positioning cylinder 41, and multiple vertical plates 43 fixedly connected to the positioning connecting plate 42; the multiple vertical plates 43 extend vertically upward and are spaced apart, and the positioning cylinder 41 is used to drive the vertical plates 43 to move up and down in the gap formed between adjacent rotating rollers 21. When the short side of the bottom cardboard needs to be aligned, the output end of the alignment cylinder 41 extends upward, driving multiple vertical plates 43 to rise between the rotating rollers 21 via the alignment connecting plate 42, until the upper part of the vertical plates 43 is higher than the top of the rotating rollers 21, i.e., the vertical plates 43 are located beside the short side of the bottom cardboard. Then, during the movement of the sliding frame 13, the alignment of the short sides of the bottom cardboard can be achieved using the vertical plates 43 on both sides. After completing the above operation, the output end of the alignment cylinder 41 retracts downward, driving the multiple vertical plates 43 to move downward, providing clearance for the gluing mechanism 5 to apply glue to the short side wall of the bottom cardboard. Specifically, to improve the stability of the alignment connecting plate 42 and the multiple vertical plates 43 during rising and falling, guide rods and sleeves can be provided.

[0026] In some embodiments, both glue application mechanisms 5 include a slide 51 mounted on the sliding frame 13, a glue gun 52 mounted on the slide 51, and an adhesive drive for reciprocating the slide 51 and the glue gun 52 along the X-axis. Specifically, the glue gun 52 is connected to the glue tank via a pipe. During the reciprocating movement of the glue gun 52 along the X-axis, the glue gun 52 can apply glue to the side wall of the short side of the base cardboard once or twice, depending on the actual situation. That is, the glue gun 52 moves from the upstream position to the downstream position to apply glue for the first time, and then returns from the downstream position to the upstream position to apply glue for the second time.

[0027] In some embodiments, the adhesive drive includes an X-axis helical rack 55 extending along the X-axis direction, an X-axis gear 54 meshing with the X-axis helical rack 55, and an adhesive drive motor 53 fixedly connected to the X-axis gear 54. The adhesive drive motor 53 is mounted on the slide 51, with its output end facing downwards. An X-axis slide rail 56 extending along the X-axis direction is provided on the frame 1, and the slide 51 is slidably mounted on the X-axis slide rail 56. By utilizing the forward or reverse rotation of the adhesive drive motor 53, the slide 51 is driven to reciprocate along the X-axis direction under the guidance of the X-axis helical rack 55. This structure ensures the smooth movement of the slide 51.

[0028] In some embodiments, the folding mechanism 7 includes a lifting cylinder 71 with its output end facing downward, a lifting pressure plate 72 connected to the output end of the lifting cylinder 71, a folding cylinder 73 disposed on the upper surface of the lifting pressure plate 72, and a folding plate 75 hinged to the output end of the folding cylinder 73 via a hinge seat 74. The lifting pressure plate 72 is used to press the face paper 20. The folding cylinder 73 is used to drive the folding plate 75 to contact the edge of the short side of the face paper 20, thereby causing the edge of the short side of the face paper 20 to fold downward. Specifically, after the face paper feeding mechanism 6 completes the feeding operation of the face paper 20, the output end of the lifting cylinder 71 extends downward, driving the lifting pressure plate 72 to move downward, and providing a downward pressing force to the face paper 20 and the bottom paper, thereby preventing displacement of the face paper 20 and the bottom paper. Subsequently, the gluing mechanism 5 operates to apply glue to the sidewall of the short side of the bottom cardboard. Then, under the action of the folding cylinder 73, the folding plate 75 acts on the edge of the short side of the top cardboard 20, causing the edge of the short side of the top cardboard 20 to fold downwards, forming a folded edge. During the continuous folding of the folding plate 75, the folded edge remains in contact with the glue on the sidewall of the short side of the bottom cardboard, thus ensuring the bonding effect between the short sides of the top and bottom cardboard. Specifically, to improve the stability of the lifting pressure plate 72 and the folding plate 75 during their rise and fall, guide rods and sleeves can be installed.

[0029] In some embodiments, an auxiliary guiding mechanism 8 is also included, which is located between the two conveying mechanisms 2. The auxiliary guiding mechanism 8 includes an auxiliary support 81 and auxiliary wheels 82 rotatably mounted on the auxiliary support 81. The bottom of the bottom cardboard is supported by the auxiliary guiding mechanism 8 to ensure that the bottom cardboard does not fall out of the gap between the two conveying mechanisms 2 when the short side of the bottom cardboard is aligned.

[0030] In some embodiments, the long-side blocking mechanism 3 includes a blocking cylinder 31 with its output end facing upwards, and a blocking plate 32 fixedly connected to the output end of the blocking cylinder 31. The blocking plate 32 is located downstream of the conveying mechanism 2, and is used to contact the downstream long side of the formed bottom paperboard. Specifically, by extending upwards or retracting downwards at the output end of the blocking cylinder 31, the blocking plate 32 is driven to rise or fall, so that the upper part of the blocking plate 32 is located on one side of the long side of the bottom paperboard, thereby limiting the downstream long side of the bottom paperboard or satisfying the need to avoid obstruction when the bottom paperboard is conveyed downstream.

[0031] In some embodiments, the paperboard feeding mechanism 6 includes a feeding cylinder 61 with its output end facing downwards, a feeding frame 62 fixedly connected to the output end of the feeding cylinder 61, a plurality of suction cups 63 disposed on the feeding frame 62, and a feeding drive component 64 for driving the feeding frame 62 to reciprocate along the X-axis. Specifically, to facilitate the operation of the next paperboard long-side folding station, a transport mechanism 9 is also provided between the paperboard feeding mechanism 6 and the frame 1. This transport mechanism 9 is used to transport the carton with the short side of the right paperboard glued downstream to facilitate the paperboard long-side folding process. In practical use, the downward extension of the output end of the feeding cylinder 61 drives the feeding rack 62 and the suction cup 63 mounted on the feeding rack 62 to move downwards, contacting and adsorbing the paperboard 20 located below the suction cup 63. Then, the output end of the feeding cylinder 61 retracts upwards, causing the paperboard 20 to rise. Under the action of the feeding drive component 64, the paperboard 20 is conveyed towards the bottom paperboard. Specifically, the feeding drive component 64 can be a motor, gear, or rack. To improve the smoothness of the movement of the feeding rack 62, guide rails and sliders can also be provided.

[0032] In some embodiments, a lifting frame 65 is also provided below the feeding rack 62. The lifting frame 65 is used to stack multiple sheets of paperboard 20 to be fed. The lifting frame 65 is connected to a lifting drive 66, which is used to drive the lifting frame 65 to rise to a set height. The lifting frame 65 and the lifting drive 66 are provided to shorten the travel of the feeding cylinder 61 and the feeding time of the paperboard 20. Specifically, the lifting frame 65 is initially positioned at its lowest point. The operator places the stacked sheets of paperboard 20 onto the lifting frame 65, and the lifting drive 66 drives the lifting frame 65 to rise to the set position. Then, in conjunction with the extension or retraction of the output end of the feeding cylinder 61, the sheets of paperboard 20 are fed one by one. More specifically, the lifting drive 66 can be a combination of a motor and a screw jack. Two screw jacks are symmetrically arranged, and each screw jack is connected to a corresponding side wall of the lifting frame 65, thereby achieving smooth rising or falling of the lifting frame 65. In this embodiment, the feeding cylinder 61 has only fully extended and fully retracted states. When the feeding cylinder 61 descends, allowing the suction cup 63 to complete the adsorption of the face cardboard 20, the lifting drive 66 operates, driving the lifting frame 65 and the multiple face cardboards 20 stacked on it to rise a short distance to accommodate the extension and retraction stroke of the feeding cylinder 61.

[0033] In summary, the present invention uses a conveying mechanism 2 to convey the formed bottom cardboard, a long-side blocking mechanism 3 and a short-side positioning mechanism 4 to position the bottom cardboard, a face cardboard feeding mechanism 6 to feed the face cardboard 20 onto the bottom cardboard, a gluing mechanism 5 to apply glue to the side wall of the short side of the bottom cardboard, and a folding mechanism 7 to fold the short side of the face cardboard 20 downwards and bond the folded edge of the face cardboard 20 to the glue on the side wall of the short side of the bottom cardboard. By using the above mechanisms, the face cardboard 20 is bonded to the bottom cardboard to form a carton wrapped with glass.
