[0002] There are many types of paper box structures, such as top and bottom covers, drawer boxes, book-shaped boxes, etc.; another example is a corrugated paper box, which has a corrugated inner box (i.e., inner box) and a cardboard outer shell (i.e., outer shell). The raw material of the cardboard outer shell is a cross-shaped structure formed by die-cutting cardboard (such as gray board). In order to realize the connection and assembly of the inner box and the outer shell to form a paper box, glue can be applied on the surface of the outer shell, such as by spraying glue on the surface of the outer shell with a glue gun so that the outer shell and the inner box are glued and connected. Gluing can be performed horizontally and vertically as required, and then the bottom of the inner box is placed in the middle area of ​​the outer shell (surface), and the side areas on the front, back, left and right sides of the middle area of ​​the outer shell are folded to the front, back, left and right sides of the inner box to realize assembly and enclosure (i.e., the outer shell is assembled and enclosed on the inner box). The middle area and the side areas are divided by indentation lines or groove lines to realize paper box forming and assembly.

[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the implementation of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field without making creative work based on the embodiments of the utility model are within the scope of protection of the utility model.

[0031] Referring to the accompanying drawings, in an example of the present embodiment, a corrugated paper box gluing and forming assembly machine has an assembly device 2 on its frame 1, and the assembly device 2 includes a lifting die 20. The lifting die 20 needs to be lowered to cooperate with the (corrugated) inner box to move down and press it on the paperboard shell 11 and continue to descend to cooperate with subsequent enclosure. After the operation is completed, it needs to be raised and reset (waiting for the next operation), and the lifting stroke of the lifting die 20 is required to be relatively large. In order to meet the demand for a relatively large lifting stroke of the lifting die 20 and make the lifting die 20 run more efficiently to improve efficiency, the following structure will be adopted in the utility model: the frame 1 has an upper support frame 10, the lifting die 20 is connected to the lower end of the lifting rod 21, the lifting rod 21 is vertically slidably connected and arranged on the upper support frame 10, and a bearing can be arranged on the upper support frame 10 so that the lifting rod 21 can slide vertically smoothly and stably for lifting; the frame 1 is also provided with a transmission mechanism 3, which includes a power motor 31, a rotating arm 32, a rocker 33, a range-extending lever 34 and a connecting rod 35, the range-extending lever 34 is connected to the upper support frame 10 through a support shaft 36, and the range-extending lever 34 is supported by the support shaft 36 to rotate back and forth, and the range-extending lever 34 swings back and forth around the support shaft 36 to cooperate with the transmission, The power motor 31 is connected to the rotating arm 32 in transmission, and the power motor 31 (such as a servo motor, which can be equipped with a reducer) drives the rotating arm 32 (or crank) to rotate, wherein the rotating arm 32 is connected to the lower end of the rocker 33 in transmission, and the upper end of the rocker 33 is connected to the input part of the range-extending lever 34 in transmission. The rotation of the rotating arm 32 drives the rocker 33 to operate, and then drives the range-extending lever 34 to swing around the support shaft 36 (up and down) through the rocker 33 (push and pull), wherein the position center of gravity of the power motor 31 is relatively lowered and runs stably; the output part of the range-extending lever 34 is connected to the lifting rod 21 by a connecting rod 35, and the swing of the range-extending lever 34 around the support shaft 36 (up and down) drives the lifting rod 21 to move up and down through the connecting rod 35, and the lifting die 20 on the lifting rod 21 moves up and down with it.

[0032] In the corrugated paper box gluing and forming assembly machine, the transmission structure is optimized to drive the lifting die 20 on the lifting rod 21 to perform an up and down lifting action, and the range-extending lever 34 is used to cooperate to form a complete transmission mechanism 3, wherein in one back-and-forth swing cycle of the range-extending lever 34, the range-extending lever 34 can amplify and increase the swing stroke of the output end of the range-extending lever 34 when the swing stroke of the input end is small, thereby meeting the demand for a relatively large lifting stroke of the lifting die 20 (and the lifting rod 21), and when the lifting stroke of the lifting die 20 is relatively large, the lifting speed of the lifting rod 21 can be relatively increased, and the time of a lifting action of the lifting rod 21 and the lifting die 20 can be relatively shortened, and the lifting and retreating can be timely, freeing up the position below for the inner box, the outer shell 11, etc. to be in place, so that the lifting die 20 can operate more efficiently, thereby improving efficiency.

[0033] The following optimization or further explanation may be performed based on the above embodiments.

[0034] The assembly device 2 has an assembly station, and the assembly station has an upper inner box position, a middle cardboard shell position, and a lower assembly enclosure cavity, forming an upper, middle, and lower three-layer layout structure; wherein the upper inner box position is a position where the corrugated inner box is in place and waiting for assembly; wherein the middle cardboard shell position is a position where the cardboard shell 11 is in place and waiting for assembly; wherein the lower assembly enclosure cavity is a structure where the shell 11 is assembled on the four sides of the inner box. The lifting die 20 is configured to lift up and down at the assembly station. During the process of the lifting die 20 descending with the lifting rod 21, it can pass through the upper, middle, and lower three-layer layout structure, cooperate with the assembly, and the lifting die 20 is reset as the lifting rod 21 rises.

[0035] Among them, the upper support frame 10 is located above the position of the upper inner box. The upper support frame 10 can adopt a cantilever structure. The upper support frame 10 can not only support the operation of the lifting rod 21, but also can cooperate to support the range-extending lever 34 in the transmission mechanism 3.

[0036] For example, the support shaft 36 is located between the input part and the output part of the range-extending lever 34, and the distance between the support shaft 36 and the input part is smaller than the distance between the support shaft 36 and the output part, so that when the swing stroke of the input end of the range-extending lever 34 is small, the swing stroke of the output end of the range-extending lever 34 is enlarged and increased. The connecting rod 35 is respectively hinged to the lifting rod 21 and the range-extending lever 34 (corresponding hinge shafts can be respectively set for hinge connection), and the rocker 33 is respectively hinged to the range-extending lever 34 and the swing arm 32 (corresponding hinge shafts can be respectively set for hinge connection), wherein the hinge shaft on the swing arm 32 is eccentrically arranged with the rotation center of the swing arm 32. Among them, the axis of the support shaft 36 is arranged horizontally.

[0037] In addition, the lifting rod 21 is provided with a locking block 22 with an adjustable relative height position, and the relative height position of the locking block 22 on the lifting rod 21 can be adjusted by loosening (such as fasteners); the locking block 22 is located at the upper part of the lifting rod 21, and the middle and lower structures of the lifting rod 21 are relatively simple, not easy to interfere with other structures, and not easy to affect assembly. The connecting rod 35 will be hinged on the locking block 22 of the lifting rod 21 (such as a hinge shaft is set on the locking block 22), and the relative height position of the locking block 22 on the lifting rod 21 can be adjusted without affecting the overall structure of the transmission mechanism 3. The upper and lower dead points of the height position of the lifting rod 21 can be adjusted to meet the assembly requirements of paper boxes of different height specifications and sizes and the adjustment and debugging requirements of the machine.

[0038] For example, the lower assembly enclosure cavity includes enclosure side panels 41 arranged front, back, left, and right. The lifting die 20 descends to cooperate with pressing the inner box and the outer shell 11 into the space surrounded by the enclosure side panels 41 on the four sides, so that the cardboard outer shell 11 (the area next to it) is enclosed on the four sides of the inner box (front, back, left, and right). Further optimization, the inner side of the enclosing side panel 41 is also distributed with an enclosure pressure-maintaining brush 42, which can not only cooperate with enclosing the cardboard outer shell 11 on the side of the inner box, but also can always have elastic pressure acting on it, and has a pressure-maintaining function, ensuring that the cardboard outer shell 11 and the inner box are in a pressure state. The adhesion and fitting ability of the enclosure pressure-maintaining brush 42 is stronger. When the inner box and the outer shell 11 are uneven or there is a size deviation between different box bodies, the enclosure pressure-maintaining effect can be achieved well, and the box body can be maintained under pressure in the lower assembly enclosure cavity.

[0039] For example, a transverse support rail 51 is provided at the position where the middle cardboard shell is in place, and two groups of transverse support rails 51 are arranged in front and back, and an enclosed material discharge channel 52 is provided between the front and rear transverse support rails 51. The transverse support rails 51 cooperate with the front and rear positions of the cardboard shell 11, and the cardboard shell 11 can be placed manually or fed to the transverse support rails 51 by a feeding device. The transverse support rails 51 can also support the cardboard shell 11 and cooperate with it (cardboard shell 11) to move horizontally to the position where the middle cardboard shell is in place, waiting for subsequent operations. The enclosed material discharge channel 52 allows the cardboard shell 11 and the inner box to pass through when they are lowered, and allows the lifting and lowering die 20 to descend and press them down into the lower assembly enclosure cavity. The spacing between the transverse support rails 51 can be adjusted to meet the requirements of different specifications and sizes.

[0040] For example, the upper inner box is connected to the position where the upper inner box is in place with a longitudinal support rail 61, and two groups of longitudinal support rails 61 are arranged on the left and right. The output end of the longitudinal support rail 61 is a lower box opening 62 for the inner box to descend and pass through; the longitudinal support rail 61 cooperates with the left and right positions of the inner box to support the inner box manually or to feed the longitudinal support rail 61 by the feeding structure. The longitudinal support rail 61 can also support the inner box and move it longitudinally to the position where the upper inner box is in place, waiting for subsequent operations. The lower box opening 62 is for the inner box to pass through when it descends, and for the lifting and lowering die 20 to descend and press it down onto the paperboard shell 11 (at the position where the middle paperboard shell is in place). Further optimization, the left and right edges of the lower box opening 62 are respectively provided with box support spring pieces 63 at the bottom edge of the box support, and the box support spring pieces 63 are respectively connected with the longitudinal material support rail 61 for supporting materials. The box support spring pieces 63 can be made of metal spring pieces for greater durability. The box support spring pieces 63 support the bottom edge of the box, which can not only smoothly support the inner box (left and right positions) connected and received by the longitudinal material support rail 61, but also enable the inner box to smoothly move longitudinally into position, and the inner box smoothly corresponds to the lower box opening 62 and the cardboard shell 11 below (where the middle cardboard shell is in place) up and down. When the lifting die 20 descends and presses the inner box, the box support spring piece 63 is pushed downward and deformed, and the box support spring piece 63 is restored after the inner box is smoothly lowered. The box support spring piece 63 and the longitudinal material support rail 61 can be highly flush and connected more smoothly.

[0041] In addition, an angle positioning descending guide component 7 is provided between the lower box opening 62 and the position where the middle cardboard shell is in place. The angle positioning descending guide component 7 is distributed at the four corners of the lower box opening 62. When the lifting die 20 descends and presses the inner box, the angle positioning descending guide component 7 guides the inner box to descend at the four corners, so that the operation is more stable, and the inner box is prevented from being distorted or shifted. The alignment between the inner box and the lower cardboard shell 11 is not easy to deviate. For example, the angle positioning descending guide component 7 includes a right-angle descending guide block 71; in addition, the angle positioning descending guide component 7 also includes a material stabilizing and anti-deflection brush 72, which is arranged next to the right-angle descending guide block 71. The material stabilizing and anti-deflection brush 72 has good nitroproperty and can assist in stabilizing the inner box and prevent it from being deflected. In particular, when there is a slight deviation in the size of the inner boxes in the same batch, the inner box can be made to descend without being distorted or shifted. The side of the lower box opening 62 can also be provided with a blocking and limiting component (such as a limiting block) for the inner box to be in place, so that the inner box can be smoothly and accurately in place. It is even possible to additionally set guide rollers between the lower box opening 62 and the position where the middle cardboard shell is in place to assist the side area of ​​the cardboard shell to be turned over in advance, so that the subsequent enclosure is smoother.

[0042] In addition, the lateral support rail 51 is also equipped with a lateral transfer plate pusher, which is arranged between the front and rear lateral support rails 51; when the cardboard shell 11 is placed on the lateral support rail 51, it can be pushed into place by the lateral transfer plate pusher, so that the cardboard shell 11 is smoothly in place and reaches the middle cardboard shell in place. The lateral back and forth movement of the lateral transfer plate pusher can be driven by a motor or a cylinder. You can even configure a material warehouse for the cardboard shell 11, and the bottom of the material warehouse is equipped with a discharge conveyor belt. The discharge conveyor belt cooperates to support the cardboard shells 11 stacked in the material warehouse and output the cardboard shells 11 one by one. This is a mature technology. It is output to the lateral support rail 51 and then pushed by the lateral transfer plate pusher, which is more efficient. In addition, a cardboard shell gluing component 8 (such as a glue gun) can be provided on the supporting path of the transverse supporting rail 51. When the cardboard shell 11 is pushed on the transverse supporting rail 51, the cardboard shell gluing component 8 can be used to spray glue on it according to demand, so that the cardboard shell 11 can be glued and connected with the inner box later, without the need to use other methods of gluing in advance. A stopper to prevent the shell from shifting longitudinally can be additionally provided on the transverse supporting rail 51 to prevent the shell from shifting longitudinally when being pushed longitudinally. A limit blocking component (such as a blocking block) for the cardboard shell 11 to be in place can also be provided at the end of the transverse supporting rail 51, so that the cardboard shell 11 can be smoothly and accurately placed in place.

[0043] In addition, the input end of the longitudinal support rail 61 is connected to a box supply conveyor belt 64, and the inner boxes can be arranged and placed on the box supply conveyor belt 64. The inner boxes are fed to the longitudinal support rail 61 by the box supply conveyor belt 64. The inner boxes can also push the inner boxes in front to move longitudinally until the lower box opening 62. In addition, a box pressing limit component 65 (such as a box pressing baffle, whose height position can be adjusted according to needs to meet the needs of boxes of different specifications and sizes) is provided above the longitudinal support rail 61. When the inner boxes are pushed forward next to each other, it is not easy to separate upwards, which is more stable.

[0044] In addition, the frame 1 is further optimized, with left and right longitudinal beams 66, the longitudinal support rails 61 connected to the longitudinal beams 66 (such as the inner side of the longitudinal beams 66), and the box support springs 63 connected to the longitudinal beams 66 (such as directly installed on the lower side of the longitudinal beams 66); in addition, the longitudinal beams 66 are also provided with side gauges 67 to prevent the inner box from lateral displacement. When the inner box is pushed to longitudinally move on the longitudinal support rails 61 and the box support springs 63, the side gauges 67 on both sides are limited to prevent the inner box from lateral displacement. Even by adjusting the mutual spacing of the longitudinal beams 66, the position adjustment of the longitudinal support rails 61, the box support springs 63, the side gauges 67, etc. can be achieved to meet the requirements of different specifications.

[0045] The upper end of the lower assembly enclosure cavity is the input port, and the lower end is the output port. The inner box and the outer shell 11 are pressed into the input port by the lifting die 20, and then the assembled box body is finally output from the output port; the lower end output port of the lower assembly enclosure cavity is connected with a material receiving conveyor belt 43, and the output box body is received by the material receiving conveyor belt 43 and then output. Continuing to optimize, the lower assembly enclosure cavity has a vertical chamber for at least two box bodies to be stacked, and the box bodies can be pushed downward next to each other, which can extend the time the box bodies stay in the lower assembly enclosure cavity to maintain pressure, and can give full play to the role of the glue applied, making it more firm; wherein, the enclosed side panels 41 are arranged on the front, back, left and right sides of the vertical chamber.
