Description

Technical Field

[0001] The utility model relates to the technical field of paper box folding, in particular to an outer ear folding mechanism for a paper box. Background Art

[0002] The bottom of the wine box is usually covered with a tongue, which is mainly glued together. The glue can be easily softened by heat treatment and removed. The bottom of the wine box can then be opened to replace the wine inside the box, replacing inferior wine with high-end wine boxes to commit counterfeiting.

[0003] Therefore, a kind of counterfeit wine box has appeared on the market, which is made by folding and gluing a whole piece of cardboard. Figure 1 As shown, it has a tongue and a side panel, and the tongue has a main body area A, side areas B located on both sides of the main body area A, and side areas C located outside the main body area A. When in use, the main body area A needs to be adhered to the bottom of the inner box, and then the side areas B and C are pushed to the sides of the inner box and adhered to the sides. When the side panels are further adhered to the inner box, the side areas B and C will be covered, so that when the tongue is to be removed, it can only be removed by cutting with a blade, so that it can be identified by people, thereby achieving an anti-counterfeiting effect.

[0004] In the prior art, a cardboard tongue folding device includes an assembly part for assembling an inner box and a folding component for folding the tongue on the assembly part onto the inner box, and includes a lifting platform and a lifting drive part for driving the lifting platform to lift and lower. The folding component is arranged on the lifting platform and lifts and lowers synchronously therewith. The folding component includes a main body A zone folding part and a side B zone folding part. The lifting platform is also provided with a folding drive part for driving the main body A zone folding part and the side B zone folding part to move forward and backward relative to the lifting platform, and the lifting drive part can drive the main body A zone folding part to move to the side C zone position. However, some gaps need to be reserved when the tongue is folded to prevent the folding part from touching the assembly part, which may cause the tongue to be easily not folded into place. When the glue does not stick to the tongue, the tongue is easily reset and bounced. Summary of the invention

[0005] Purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a paper box outer ear folding mechanism, which can be clamped after the tongue is folded, so that the tongue forms a crease, which can reduce the force of the tongue resetting and make it more stable during processing.

[0006] The utility model discloses a paper box outer ear folding mechanism, comprising a base, a mounting seat and an advance and retreat driving member driving the mounting seat to move forward and backward, the mounting seat is provided with a folding member and a lifting driving member driving the folding member to move up and down on the mounting seat, the folding member comprises a top folding member and side folding members located on opposite sides of the top folding member, and is characterized in that: a lifting frame is also provided on the mounting seat, the top folding member and the side folding member are both arranged on the lifting frame, and the lifting frame is also provided with a top driving member for driving the top folding member to move up and down and a side driving member for driving the side folding members on both sides to move closer or separate relatively.

[0007] When the above technical solution is adopted, the paper sheet is transported to the box folding machine and clamped by the box folding machine. Further, the top folding piece is moved to the position of area A of the tongue body by the advance and retreat driving member, and then the lifting and lowering driving member drives the lifting frame to rise and fall so that area A is relatively folded, and the top folding piece is further moved to the position of area C, and the advance and retreat driving member drives the mounting seat forward. At this time, the side driving member contacts area B of the side of the tongue, and the top folding member contacts area C of the side of the tongue, thereby driving the side areas B and C of the tongue to be folded. After folding, the top driving member is further used to drive the top folding member to be pressed down, and the side driving member drives the side folding members to be pressed together, so that the tongue is pressed out of a folding mark, reducing its reset force, and making it more stable during processing.

[0008] The utility model is further configured as follows: a plurality of bristles are arranged on one side of the top folding piece away from the mounting seat.

[0009] By adopting the above technical solution, when folding, the bristles first contact the A area of ​​the tongue piece, and then can play a buffering role to avoid damaging the tongue piece.

[0010] The utility model is further configured as follows: an articulated arm is arranged on the lifting frame at a position corresponding to the top folding part; one end of the articulated arm is hingedly cooperated with the lifting frame, and the other end is fixedly connected to the top folding part to form a suspended support for the top folding part; one end of the top driving part is hingedly arranged on the lifting frame, and the other end is hingedly arranged on the articulated arm.

[0011] By adopting the above technical solution, since the installation space on the front side of the structure is limited, the top folding part is driven to swing and press together by driving the articulated arm to rotate, so that the space can be fully utilized, and the top driving part can be installed as a whole at an angle, which is not easy to damage the top driving part.

[0012] A further configuration of the utility model is that a middle portion of the articulated arm is also provided with an escape hole for exposing a portion of the top driving member.

[0013] The above technical solution can facilitate the installation of the top drive.

[0014] The utility model is further configured as follows: a mounting plate is arranged on the side driving member, the side folding member is guided and adjusted on the mounting plate, and also includes a fixing member for fixing the side folding member after the side folding member is guided and adjusted.

[0015] By adopting the above technical solution, the spacing between the side folding parts of the tongue pieces on both sides can be roughly adjusted, so that it is suitable for processing and folding tongue pieces of different widths.

[0016] Further configuration of the utility model: the lifting frame is also provided with a guide rail arranged along the displacement direction of the side folding member, the side driving member is provided with a guide block on the side facing the guide rail, the guide block guides and slides on the guide rail, and the lifting frame is provided with elastic buffer parts on opposite sides of the guide block, and the elastic buffer parts are against the guide block.

[0017] By adopting the above technical solution, when the device has a relative offset, the tongue piece is easily damaged because the side driving member controls the side folding member to clamp and displace and fix it. At this time, the guide block can compress the elastic buffer member, thereby making the side driving member adaptively adjusted, with better stability and stronger practicality.

[0027] The utility model discloses a paper box outer ear folding mechanism, including a base 1, a mounting seat 2 and an advance and retreat driving member 3 for driving the mounting seat 2 to advance and retreat, the mounting seat 2 is provided with a folding member 5 and a lifting driving member 4 for driving the folding member 5 to rise and fall on the mounting seat 2, the advance and retreat driving member 3 and the lifting driving member 4 are most preferably motors and synchronous belts, and of course they can also be cylinders or electric cylinders, the folding member 5 includes a top folding member 51 and side folding members 52 located on opposite sides of the top folding member 51 (the top folding member 51 and the side folding members 52 can both be folding plates or folding rollers), the utility model implementation case In the figure, the mounting seat 2 is also provided with a lifting frame 6, and the top folding member 51 and the side folding member 52 are both arranged on the lifting frame 6, and the lifting frame 6 is also provided with a top driving member 7 for driving the top folding member 51 to rise and fall, and a side driving member 8 for driving the side folding members 52 on both sides to move closer or apart. The top driving member 7 and the side driving member 8 are most preferably cylinders, and of course, motors or electric cylinders can also be used. When the lifting frame 6 and the mounting seat 2 are moving, it is most preferred to use guide rails and guide blocks to cooperate for guided sliding, and the stability is relatively good. This technical solution belongs to the prior art and will not be introduced in detail in this article.

[0028] When the above technical solution is adopted, the paper sheet is transported to the box folding machine and clamped by the box folding machine. Further, the top folding piece 51 is moved to the position of the tongue body area A through the advance and retreat drive member 3, and then the lifting drive member 4 drives the lifting frame 6 to rise and fall so that the main body area A is relatively folded, and the top folding piece 51 is further moved to the C area position, and the advance and retreat drive member 3 drives the mounting seat 2 forward. At this time, the side drive member 8 contacts the side area B of the tongue, and the top folding piece 51 contacts the side area C of the tongue, thereby driving the side areas B and C of the tongue to be folded. After folding, the top folding piece 51 is further pressed down by the top drive member 7, and the side drive member 8 drives the side folding piece 52 to be pressed together, so that the tongue is pressed out of a folding mark, reducing its reset force, so that it has better stability during processing.

[0029] A plurality of bristles 9 are arranged on one side of the top folding member 51 away from the mounting seat 2. When folded, the bristles 9 first contact the main body A area of ​​the tongue piece, and then can play a buffering role to avoid damaging the tongue piece.

[0030] An articulated arm 10 is provided on the lifting frame 6 at a position corresponding to the top folding piece 51. One end of the articulated arm 10 is hingedly cooperated with the lifting frame 6, and the other end is fixedly connected to the top folding piece 51 to form a suspended support for the top folding piece 51. One end of the top driving piece 7 is hingedly set on the lifting frame 6, and the other end is hingedly set on the articulated arm 10. Since the installation space on the front side of the structure is limited, the top folding piece 51 is driven to swing and press together by driving the articulated arm 10 to rotate, thereby making full use of the space, and the top driving piece 7 can also be installed tilted as a whole, which is not easy to damage the top driving piece 7.

[0031] The middle part of the articulated arm 10 is also provided with an escape hole 20 for partially exposing the top driving member 7, so as to facilitate the installation of the top driving member 7.

[0032] The side driving member 8 is provided with a mounting plate 30, and the side folding member 52 is guided and adjusted on the mounting plate 30. It also includes a fixing member for fixing the side folding member 52 after the side folding member 52 is guided and adjusted (it is most preferred to fix it with bolts, and bolts and other fixing members belong to the prior art and are not shown in the figure). The spacing between the side folding members 52 on both sides can be roughly adjusted, so as to be suitable for processing and folding tongues of different widths.

[0033] The lifting frame 6 is also provided with a guide rail 40 arranged along the displacement direction of the side folding member 52, and the side driving member 8 is provided with a guide block 50 on the side facing the guide rail 40, and the guide block 50 guides and slides on the guide rail 40, and the lifting frame 6 is provided with elastic buffer members 60 on the opposite sides of the guide block 50 (the elastic buffer member 60 is most preferably a spring, and of course it can also be a spring sheet or an elastic gasket, etc.), and the elastic buffer member 60 is against the guide block 50. When the device has a relative offset, because the side driving member 8 controls the side folding member 52 to clamp, displace and fix, it is easy to clamp the tongue piece. At this time, the guide block 50 can compress the elastic buffer member 60, so that the side driving member 8 can be adaptively adjusted, with better stability and stronger practicality.
