Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of box making, in particular to a forming module and an octagonal box forming method. BACKGROUND

[0002] The octagonal box making machine on the market needs to vertically place the sprayed surrounding plate on one side of the mold, and the mold moves horizontally towards the forming station. During the movement, one side plate of the surrounding plate is fixed to the front side of the mold, so that the mold pushes the surrounding plate to the forming station. When the surrounding plate moves, it needs to be preliminarily bent by a limiting column. Then the bottom plate is conveyed to the lower side of the mold and is moved upwards to be attached to the lower surface of the mold. At the same time, the bottom edge of the surrounding plate is aligned with the periphery of the bottom plate. Finally, five circumferential pressing plates (four 120-degree angle plates and one straight plate) are actuated inward to press the eight side plates of the surrounding plate onto the bottom plate. However, the following problems exist: During the forming process, the eight side plates of the surrounding plate need to surround the periphery of the bottom plate. Since one side plate of the surrounding plate is fixed to the front side of the mold, it is easy to interfere with the bottom plate when it is moved upwards to be attached to the lower surface of the mold, causing damage to the side plate or the bottom plate, or scratching the glue on the bottom edge of the side plate, which causes the glue to overflow onto the mold, making it difficult to demold the octagonal box, and causing the side plate and the bottom plate to stick together.

[0050] Referring to Figure 1 and Figure 2 The embodiment discloses a forming module 1 applied to a box making machine, which is used for making a multi-angle box formed by a bottom plate 5 and a surrounding plate 6, and the forming module 1 comprises a cavity unit 11, a mold unit 12, a supporting unit 13, a pressing unit 14, a swing arm unit 15, a demolding unit 16 and a box turning unit 17, and the cavity unit 11, the mold unit 12, the supporting unit 13, the pressing unit 14, the swing arm unit 15, the demolding unit 16 and the box turning unit 17 can be installed on a rack 18.

[0051] It should be noted that the rack 18 can comprise a plurality of sub-racks, and the plurality of sub-racks can be independent or connected with each other, each unit can be installed on different sub-racks, or a plurality of units can be installed on the same sub-rack, that is, the rack 18 is a general term, and the relative positioning and installation between the units can be completed, and it is not limited that all units must be installed on a specific overall rack, in addition, some relatively independent units can also be directly installed on the ground. For example, the mold unit 12 and the supporting unit 13 can be simultaneously installed on a sub-rack, the cavity unit 11, the pressing unit 14, the swing arm unit 15 and the demolding unit 16 can be simultaneously installed on another sub-rack, and the box turning unit 17 can also be directly installed on the ground. In order to facilitate the description of the application and simplify the description, the embodiment will be uniformly described as the cavity unit 11, the mold unit 12, the supporting unit 13, the pressing unit 14, the swing arm unit 15, the demolding unit 16 and the box turning unit 17 are installed on the rack 18.

[0052] Referring to Figure 1 and Figure 2In the embodiment, the cavity unit 11 is configured to accommodate the prepared polygonal box; the mold unit 12 is configured to load the bottom plate 5, and the mold unit 12 is configured to move towards or away from the cavity unit 11; the supporting unit 13 is configured to clamp the surrounding plate 6 to the mold unit 12, and the supporting unit 13 is located on the side of the mold unit 12 facing the cavity unit 11, and the supporting unit 13 is configured to move with the mold unit 12 towards the cavity unit 11; the pressing unit 14 is configured to press the surrounding plate 6, and the pressing unit 14 is configured to move towards or away from the mold unit 12 to press a part of the bottom edge of the surrounding plate 6 to a part of the periphery of the bottom plate 5; the swing arm unit 15 is configured to support the surrounding plate 6, and the two swing arm units 15 are located on the two sides of the input end of the cavity unit 11, and the swing arm unit 15 is configured to flip relative to the mold unit 12 to bend the surrounding plate 6; the demolding unit 16 is configured to demold the prepared polygonal box, and the demolding unit 16 is located at the output end of the cavity unit 11; and the turning unit 17 is configured to turn the prepared polygonal box, and the turning unit 17 is located at the output end of the cavity unit 11.

[0053] The molding module 1 provided by the above scheme can be used to prepare a polygonal box formed by the bottom plate 5 and the surrounding plate 6, and the materials of the bottom plate 5 and the surrounding plate 6 can be paper or density board, and the polygonal box can be a five-corner box, a six-corner box, an eight-corner box, etc. For the convenience of understanding, the eight-corner box made of density board will be taken as an example for a detailed description, and at this time, the swing arm unit 15 can also have another function, i.e., after bending the surrounding plate 6, the swing arm unit 15 can also clamp the surrounding plate 6 to the mold unit 12 to press a part of the bottom edge of the surrounding plate 6 to a part of the periphery of the bottom plate 5.

[0054] Preferably, in the embodiment, the molding module 1 is a vertical structure, wherein the mold unit 12 is located above the cavity unit 11, the mold unit 12 moves up and down along the vertical direction, the supporting unit 13 is located below the mold unit 12, and the supporting unit 13 also moves up and down along the vertical direction, the pressing unit 14 moves along the horizontal direction (it can also be considered that the pressing unit 14 moves towards or away from the mold unit 12 along the direction perpendicular to the moving direction of the mold unit 12) to press a part of the surrounding plate 6 to a part of the periphery of the bottom plate 5, and the swing arm unit 15 flips upwards to bend the two ends of the surrounding plate 6 upwards. It can be known that when the molding module 1 is a vertical structure, the bottom plate 5 is loaded on the mold unit 12 in a vertical manner, and the surrounding plate 6 is placed above the supporting unit 13 and / or the swing arm unit 15 in a horizontal manner.

[0055] In other embodiments, the forming module 1 can also be a horizontal structure, in which the mold unit 12, the supporting unit 13 and the cavity unit 11 are arranged in sequence along the horizontal direction, the mold unit 12 and the supporting unit 13 can move reciprocatingly along the horizontal direction, and the pressing unit 14 moves along the horizontal direction (it can also be considered that the pressing unit 14 moves towards or away from the mold unit 12 along the direction perpendicular to the moving direction of the mold unit 12) for pressing a part of the surrounding plate 6 and a part of the peripheral edge of the bottom plate 5. It is known that the bottom plate 5 is in a horizontal state and the surrounding plate 6 is in a vertical state. At this time, because the mold unit 12 moves horizontally, the surrounding plate 6 is bent on the horizontal plane during the preparation process, and the surrounding plate 6 does not need to be deformed by supporting, and the swing arm unit 15 can not be needed, and other structures such as two limiting columns can be used to replace the bending effect of the swing arm unit 15 on the surrounding plate 6, and the turnover unit 17 can also not be needed (the octagonal box prepared by the horizontal structure does not need to be turned over), and the demolding unit 16 can also not be needed (such as using gravity demolding).

[0056] Of course, the forming module 1 is preferably a vertical structure, which can solve the problem of tearing of the surrounding plate 6 caused by the downward sagging of the two ends of the surrounding plate 6 under the action of gravity when the surrounding plate 6 is bent horizontally. The following will be described in detail with the forming module 1 as a vertical structure.

[0057] It should be noted that in other embodiments, when preparing an octagonal box of paper board material, the surrounding plate 6 of the paper board material can not need to be bent in advance, and therefore the swing arm unit 15 can not be needed, and the input end of the cavity unit 11 can be used to constrain the surrounding plate 6 to bend. Of course, it is preferable to have the swing arm unit 15.

[0058] In the above scheme, when the forming module 1 is used to prepare a multi-corner box formed by the bottom plate 5 and the surrounding plate 6, first, the bottom plate 5 is loaded onto the mold unit 12, and the surrounding plate 6 can be moved between the mold unit 12 and the supporting unit 13. At this time, the supporting unit 13 and the swing arm unit 15 can be supported on the side of the surrounding plate 6 away from the mold unit 12. Specifically, the supporting unit 13 and the swing arm unit 15 can be supported on the bottom surface of the surrounding plate 6. Then, the mold unit 12 with the bottom plate 5 moves towards the cavity unit 11, pre-presses the surrounding plate 6 on the supporting unit 13, and realizes the initial clamping of the surrounding plate 6. At this time, the supporting unit 13 can press the part of the bottom edge of the surrounding plate 6 close to the middle position and the lower periphery of the bottom plate 5, so that the front edge of the multi-corner box is bonded under the action of the mold unit 12 and the supporting unit 13. Then, the mold unit 12 and the supporting unit 13 continue to move towards the cavity unit 11 (i.e. continue to descend), the swing arm unit 15 is turned over to bend the surrounding plate 6, and the surrounding plate 6 is clamped on both sides of the mold unit 12 to press the part of the bottom edge of the surrounding plate 6 and the part of the periphery of the bottom plate 5, so that the side edge of the multi-corner box is initially bonded under the action of the swing arm unit 15. At this time, the lower half of the multi-corner box is roughly formed. Finally, with the continuous movement of the mold unit 12 and the supporting unit 13, the side edge of the multi-corner box is completely bonded in the cavity unit, and at the same time, the pressing unit 14 moves towards the mold unit 12, so that the rear edge of the multi-corner box is bonded under the action of the pressing unit 14. In this way, the preparation of the multi-corner box is realized by loading the bottom plate 5 first and then pressing the surrounding plate 6, which solves the problem of interference between the bottom plate 5 and the surrounding plate 6 and solves the problem of glue overflow. The whole structure is simple, the action is simple, and the bonding effect is good.

[0059] Referring to Figure 3 In this embodiment, the cavity unit 11 includes two groups of oppositely arranged cavity assemblies 111 and a cavity 112 formed by the two cavity assemblies 111 to accommodate the prepared multi-corner box. The cavity assembly 111 includes a fourth sliding seat 1111, two forming cavity columns 1112, and a seventh driving device 1113. The fourth sliding seat 1111 slides on the rack 18, and the two forming cavity columns 1112 are spaced apart on the fourth sliding seat 1111. Specifically, the fourth sliding seat 1111 slides on the rack 18 in the horizontal direction through the slide rail, and the forming cavity column 1112 extends in the vertical direction. Preferably, the forming cavity column 1112 is a right-angle structure composed of two rectangular rods. The seventh driving device 1113 drives the fourth sliding seat 1111 to move the forming cavity column 1112, thereby adjusting the size of the cavity 112 to adapt to the preparation of multi-corner boxes of different specifications and to avoid interference with the demolding unit 16. When an octagonal box is prepared as an example, the two cavity assemblies 111 can be specifically used to complete the complete bonding of the two vertical side edges of the octagonal box.

[0060] Preferably, the seventh driving device 1113 is a pneumatic cylinder, the fixed end of the pneumatic cylinder is connected to the rack 18, and the output end of the pneumatic cylinder is connected to the fourth sliding base 1111. Of course, the seventh driving device 1113 can also be an oil cylinder, an electric push rod or other known driving devices, and the present application does not make a specific limitation on the seventh driving device 1113.

[0061] Referring to Figure 4 In the embodiment, the mold unit 12 and the supporting unit 13 are slidably arranged on the rack 18 by the same set of sliding rails, so as to better control the consistency when the mold unit 12 and the supporting unit 13 move synchronously and the accuracy of the clamping position. Specifically, the mold unit 12 is located above the supporting unit 13, and when the mold unit 12 is in the highest initial position, a space is kept between the mold unit 12 and the supporting unit 13, so that there is enough space to place the coaming 6 between the mold unit 12 and the supporting unit 13. The first driving device 101 is arranged on the rack 18 and drives the mold unit 12 to move up and down. The second driving device 102 is also arranged on the rack 18 and drives the supporting unit 13 to move up and down.

[0062] As an example, the first driving device 101 and the second driving device 102 can both adopt the mode of motor cooperating with belt to respectively drive the mold unit 12 and the supporting unit 13, so as to adapt to the large stroke of the mold unit 12 and the supporting unit 13.

[0063] Of course, the first driving device 101 and the second driving device 102 can also adopt other driving modes, such as motor driving screw block structure, motor driving gear rack structure, motor driving chain wheel chain structure, long pneumatic cylinder, long oil cylinder, etc., and the present application does not make a specific limitation on the first driving device 101 and the second driving device 102.

[0064] Referring to Figure 5 to Figure 7 In the embodiment, the mold unit 12 includes a first sliding base 121, a mold 122 and a negative pressure device 123 for adsorbing the bottom plate 5. The mold 122 is arranged on the first sliding base 121, the first sliding base 121 is slidably arranged on the rack 18, and the first driving device 101 drives the first sliding base 121 to move the mold 122. The negative pressure device 123 is located in the mold 122 and corresponds to the end face 1221 of the bottom plate 5. In this way, the bottom plate 5 is adsorbed on the end face 1221 of the mold 122 by the negative pressure device 123, which is convenient and fast.
