Technical Field

[0001] This invention relates to the field of corrugated cardboard box processing, and more specifically to a corrugated cardboard box and its production system and method. Background Technology

[0002] Corrugated cardboard is die-cut, creasing, and stapling or gluing to create corrugated boxes. Corrugated boxes are the most widely used packaging product, consistently ranking first in usage among all packaging materials. For over half a century, corrugated boxes have gradually replaced wooden crates and other transport packaging containers due to their superior performance and easy processing, becoming the mainstay of transport packaging. Besides protecting goods and facilitating warehousing and transportation, they also enhance the appearance and promote the product. However, existing corrugated boxes, due to their inherent low strength, can deform when stacked in excessive layers, failing to continue protecting the contents and impacting transportation efficiency. Summary of the Invention

[0003] This invention provides a corrugated cardboard box and its production system and method, with the aim of increasing the longitudinal load-bearing capacity of the corrugated cardboard box.

[0004] The above objectives are achieved through the following technical solutions:

Detailed Implementation

[0026] In the description of this invention, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0027] The invention will now be further described with reference to the accompanying drawings.

[0028] like Figures 1 to 5 To achieve the purpose of injecting epoxy resin into the grooves of the corrugated cardboard;

[0029] The slide 101 is fixedly connected to the worktable 11, the material box 12 is slidably connected inside the slide 101, a plurality of first compression springs 201 are fixedly connected between the material box 12 and the slide 101, the needle holder 13 is slidably connected inside the material box 12, and a plurality of needles 301 are fixedly connected to the needle holder 13, each needle 301 being slidably connected to the material box 12.

[0030] The material box 12 is located above the corrugated cardboard. Driving the material box 12 downwards causes its front and rear sides to contact the raised portions of the corrugated cardboard, while the left and right sides of the corrugated cardboard contact the slide 101, thus sealing the space above the corrugated cardboard. As the material box 12 moves downwards, the syringe holder 13 is simultaneously driven downwards, causing the syringe 301 to move downwards to the recessed portion of the corrugated cardboard. When the material box 12 stops moving, the syringe 301 continues to move downwards, causing its lower end to press against the corrugated cardboard to prevent splashing during epoxy resin injection. As the syringe 301 continues to move, its upper end moves into the material box 12. The epoxy resin solution and curing agent are mixed externally and continuously injected into the material box 12. The epoxy resin solution can then enter through the upper end of the syringe 301 and be injected from... The syringe 301 flows out from its lower end and falls onto the corrugated cardboard, continuing to drive the syringe holder 13 to move the syringe 301 upward, gradually filling the recessed parts of the corrugated cardboard. Simultaneously, as the syringe 301 injects, the corrugated cardboard is heated by warm air, accelerating the solidification of the epoxy resin. This achieves the purpose of adding epoxy resin into the grooves of the corrugated cardboard. The syringes 301 are arranged in two rows, adding solid epoxy resin between adjacent rows of corrugated cardboard, thus increasing the stability of the corrugated box. The spaced solid epoxy resin within the corrugated cardboard reduces the overall weight of the corrugated box. A tension spring is fixed between the syringe holder 13 and the material box 12. Each time the syringe holder 13 is pressed down, the tension spring resets it, while the material box 12 resets via the first compression spring 201 compressed during downward movement, thus achieving repetitive operation.

[0031] like Figure 1 To achieve the goal of turning cardboard into corrugated cardboard;

[0032] Two pressure rollers 102 are rotatably connected to the worktable 11. Each pressure roller 102 has multiple axial protrusions. A belt is placed between the two ends of the two pressure rollers 102. A first motor is fixedly connected to the worktable 11. The output shaft of the first motor is fixedly connected to one of the pressure rollers 102. A conveyor belt 103 is provided on the worktable 11, and a drive device is provided on the conveyor belt 103.

[0033] The cardboard is placed between two pressure rollers 102, and the first motor is driven to rotate, which in turn drives the two pressure rollers 102 to mesh and rotate. This causes the protrusions on the pressure rollers 102 to squeeze the cardboard relative to each other, thus squeezing the horizontal cardboard into corrugated cardboard. The corrugated cardboard is then conveyed forward by the rotation of the two pressure rollers 102 at the rear end of the system. After the corrugated cardboard is injected with solid epoxy resin, it is continued to be conveyed forward by the conveyor belt 103 for subsequent bending processing.

[0034] like Figures 1 to 3 This is to accelerate the solidification of the epoxy resin solution;

[0035] The lifting platform 401 is slidably connected to the underside of the carriage 101. A second compression spring 402 is fixedly connected between the lifting platform 401 and the carriage 101. The heater 14 is fixedly connected to the underside of the lifting platform 401.

[0036] During the epoxy resin injection process, the high temperature can accelerate the curing of the epoxy resin, thereby driving the carriage 101 to move upward, which in turn drives the heater 14 to move upward. The heater 14 has a through hole on top, and the operating table 11 has an opening with the same shape as the heater 14. The hot air blown out of the heater 14 can accelerate the curing of the epoxy resin, while avoiding deformation caused by the epoxy resin soaking the corrugated cardboard. After the epoxy resin injection is completed, the lifting table 401 is driven to move downward, driving the heater 14 to move downward, thereby avoiding the heater 14 from continuously heating the corrugated cardboard and causing it to become brittle.

[0037] like Figure 6 and Figure 7 To achieve the purpose of driving the material box, needle holder and lifting platform to move in stages;

[0038] The rotating shaft 15 is rotatably connected to the slide 101. The second motor is fixedly connected to the slide 101. The output shaft of the second motor is fixedly connected to the rotating shaft 15. The two first cams 501 are fixedly connected to the rotating shaft 15. The upper end of the material box 12 is in contact with the two first cams 501. The two second cams 502 are fixedly connected to the rotating shaft 15. The needle holder 13 is in contact with the two second cams 502. The two third cams 503 are fixedly connected to the rotating shaft 15. The lifting platform 401 is in contact with the two third cams 503.

[0039] The first cam 501, the second cam 502, and the third cam 503 are all composed of two long-distance arcs and two short-distance arcs. The short-distance arcs at both ends of the first cam 501 and the second cam 502 are the same. Initially, the material box 12 and the syringe holder 13 are both located above the slide 101. The second motor drives the rotating shaft 15 to rotate, which in turn drives the first cam 501 and the second cam 502 to rotate. Both cams then change from short-distance arcs to long-distance arcs, thus driving the material box 12 and the syringe holder 13 to move downwards simultaneously. The distance from the long-distance arc on the first cam 501 to the center of rotation is less than the distance from the long-distance arc on the second cam 502 to the center of rotation. As the rotating shaft 15 rotates, the material box 12 moves downwards until it contacts the corrugated plate protrusion and then stops moving. As the rotating shaft 15 rotates, the material box 12 stops moving and... The syringe holder 13 can continue to move downwards; the length of the long arc of the second cam 502 is shorter than that of the long arc of the first cam 501, thus ensuring that when the material box 12 contacts the corrugated cardboard, the syringe 301 is in the injection stage, and after the syringe 301 finishes injection, it can move upwards before the material box 12, thus preventing the epoxy resin solution from overflowing the corrugated cardboard. During the rotation of the drive shaft 15, the third cam 503 is also rotated. The third cam 503 consists of two short arcs and two long arcs. Initially, the short arc of the third cam 503 contacts the lifting platform 401. As the shaft 15 rotates, the third cam 503 pushes the lifting platform 401 upwards, and at the same time, the second compression spring 402 is compressed, thus heating it while injecting epoxy resin. Afterwards, the compressed second compression spring 402 similarly drives the lifting platform 401 to reset.

[0040] like Figure 8 To achieve the purpose of bonding the cardboard and the corrugated board;

[0041] Two paper wheels 104 are rotatably connected to the workbench 11, and two rubber wheels 106 are also rotatably connected to the workbench 11.

[0042] The conveyor belt 103 continues to transport the filled corrugated cardboard forward. The corrugated cardboard passes through two rubber rollers 106, and glue is applied to its upper and lower sides. Multiple sheets of cardboard are wound on the paper rollers 104. At the same time, the length of the cardboard on the lower paper roller 104 is twice the length of the cardboard on the upper paper roller 104. The two paper rollers 104 rotate, and the cardboard on the upper and lower sides of the corrugated cardboard is glued together. The lower paper roller 104 is continuously driven, and the upper paper roller 104 is driven intermittently, so that the cardboard on the upper part of the corrugated cardboard is interrupted. The corrugated cardboard is then bent at the interruption point, thus forming a three-layer cardboard and two-layer corrugated cardboard corrugated paper, thereby reducing consumption and the thickness of the corrugated cardboard while ensuring strength.

[0043] like Figure 9This is to achieve the purpose of intermittently driving the upper paper roller;

[0044] The belt tooth 105 is connected between two paper rollers 104. Two pressure rollers 603 are slidably connected on the worktable 11. Each pressure roller 603 is in contact with the corresponding belt tooth 105. Two electric pneumatic rods are fixed on the worktable 11. The moving end of each electric pneumatic rod is rotatably connected to the corresponding pressure roller 603.

[0045] While driving the lower paper wheel 104 to rotate, the electric pneumatic rod is controlled to extend and retract cyclically. When the electric pneumatic rod extends, it drives the pressure roller 603 to squeeze the belt tooth 105, thereby making the belt tooth 105 and both paper wheels 104 mesh and connect. As a result, the lower paper wheel 104 can drive the upper paper wheel 104 to rotate. Similarly, when the electric pneumatic rod retracts, there is a gap between the belt tooth 105 and the paper wheel 104, so the upper paper wheel 104 cannot be continued to be meshed and driven to rotate, thus achieving the purpose of intermittently driving the upper paper wheel.

[0046] like Figure 9 To achieve the purpose of corrugated cardboard after bending and bonding the cardboard;

[0047] A rotating plate 16 is rotatably connected to the workbench 11, and a first connecting rod 601 is fixedly connected to each of the two rotating ends of the rotating plate 16.

[0048] The first connecting rod 601 is driven to rotate, which in turn causes the rotating plate 16 to rotate around the rotating point, thereby causing the cardboard above to bend backward.

[0049] like Figure 9 In order to save power sources;

[0050] Each first link 601 is rotatably connected to a second link 602 at the other end, and each second link 602 is rotatably connected to a corresponding pressure roller 603 at the other end.

[0051] When the electric pneumatic rod is extended or retracted, it drives the pressure roller 603 to move back and forth. As a result, one end of the second link 602 moves back and forth with the pressure roller 603. Then, the other end of the second link 602 drives one end of the first link 601 to move back and forth. As a result, the first link 601 is driven to rotate around its other end. Thus, during the intermittent control of cardboard bonding, the bonded corrugated cardboard can also be intermittently bent, thereby reducing the power source.

[0052] like Figure 10 A corrugated cardboard box produced by a corrugated cardboard box production system contains two layers of corrugated board and three layers of cardboard, with solid epoxy resin fixed in the grooves of the corrugated board.

[0053] like Figure 11 A method for producing corrugated cardboard boxes, characterized by comprising the following steps;

[0054] Step 1: Place the cardboard at the rear end of the workbench 11 and wind the cardboard around the two paper rollers 104;

[0055] Step 2: Drive the pressure roller 102 to rotate, and simultaneously start the conveyor belt 103;

[0056] Step 3: Turn on the heater 14 to drive the rotating shaft 15 to rotate, and at the same time, intermittently drive the pressure roller 603 to move back and forth to form corrugated cardboard;

[0057] Step 4: Cut and bend the corrugated cardboard.
