Description

Technical Field

[0001] This invention relates to the field of packaging technology, specifically to a biodegradable and environmentally friendly paper box folding packaging device and method. Background Technology

[0002] Cardboard boxes are a common packaging material for products. When cardboard boxes arrive, they are usually folded into a flat shape. When they need to be packed, they need to be folded into a box shape according to the pre-folding lines. Before folding into a box shape, pre-folding lines are often made on the cardboard box to achieve a pre-folded state.

[0003] In existing technologies, when pre-folding paper boxes, a creasing machine is typically used to operate linearly, driving the paper box to fold by a limit frame. Because the folding force is uniform, the material is damaged due to stress concentration at the initial bending stage, which can cause internal cracks and poor bending effect. At the same time, the linear creasing method can easily cause stress concentration at a single point, which can easily cause material breakage and loss when folding the paper box, resulting in material waste and low practicality. Therefore, there is a need for a device that can adjust the folding force according to the folding angle while using curved creasing to avoid insufficient bending effect and low practicality.

The side end of the connecting block is provided with a pulling frame. The side of the pulling frame away from the connecting block is provided with an opening. A sliding sleeve is provided in the opening. Each end of the pulling frame is provided with a fitting rod. The fitting rod is located in an annular groove on the sliding sleeve. The sliding sleeve is vertically slidably connected to the power rod. The bottom of the power rod is rotatably connected to the auxiliary frame. The side end of the auxiliary frame is connected to the inner wall of the linkage arm on the adjacent side. The bottom of the sliding sleeve is movably connected to the top of the auxiliary frame through a telescopic spring. The top two sides of the sliding sleeve are symmetrically hinged with hinge rods. The other end of the hinge rod is hinged to the side end of the contact block. The contact block is slidably disposed in a connecting groove in the H-shaped frame at the top of the power rod.

[0009] Preferably, the bottom of the power rod is connected to the middle of the linkage bevel gear, and an auxiliary bevel gear meshes with the side end of the linkage bevel gear. The included angle between the auxiliary bevel gear and the linkage bevel gear is set at 90 degrees.

The other end of the auxiliary transmission belt is sleeved on the rotatable connection between the control bevel gear and the sliding seat.

[0012] Preferably, the method of using the biodegradable and environmentally friendly paper box folding packaging device includes the following steps: S1: The operator controls the drive motor to rotate the rotating shaft and linkage arm on the rotating seat, which facilitates the folding of the cardboard box through the L-shaped connecting frame and the limiting frame. In the initial stage of folding, the force of folding causes the resistance block to slide along the sliding groove under the action of the telescopic rod. This allows the two resistance wedges to cooperate with the resistance wedge frame and slide along the resistance groove under the action of the compression spring, thus dispersing the folding force. During the movement of the two resistance wedges, the L-shaped contact frame cooperates with the control wedge to squeeze the trigger rod to slide outward along the mating groove under the action of the spring telescopic rod. After the resistance block moves to the side of the sliding groove, the resistance block stops sliding, the compression spring contracts to its maximum, and the folding force is directly applied to the unloading frame on the linkage arm, thus restoring the folding force. S2: When the resistance block abuts against the inner wall of the sliding groove, the trigger rod and the bottom of the connecting block cooperate with each other, thereby driving the connecting block to move upward. Then, the pulling frame moves upward synchronously. Under the cooperation of the fitting rod and the annular groove, the sliding sleeve moves upward along the power rod, thereby driving the telescopic spring to stretch. Under the action of the hinge rod, the two abutting blocks slide away from each other along a connecting groove on the H-shaped frame and abut against the inner wall of the rotating sleeve. Under the action of the rotating shaft and the first transmission belt, the auxiliary shaft deflects synchronously. Then, under the cooperation of the auxiliary bevel gear and the linkage bevel gear, the power rod and the sliding sleeve rotate synchronously. Through the abutting block, the rotating sleeve and the transmission shaft rotate, driving the indentation assembly and the marking assembly to work synchronously. S3: When the drive shaft rotates, it drives the linkage shaft to rotate via the second drive belt. Through the cooperation of the drive crank and the auxiliary crank, the sliding seat is driven to reciprocate along the limit frame. During the folding of the cardboard box, the telescopic arm is controlled to work in conjunction with the cardboard box forming. During the operation of the telescopic arm, the cooperation between the spring rod and the locking sleeve is controlled to keep the second drive belt stably transmitting power on the linkage shaft and the drive shaft. Through the cooperation between the bevel gear and the drive toothed rod, the arc-shaped cam is driven by the auxiliary drive belt to roll along the fold on the inner side of the cardboard box to make indentations, and reciprocates with the cooperation of the sliding seat.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: In this invention, when the device is in use, the operator controls the drive component to reduce the initial force applied to the cardboard box by the force-relieving component. The applied force is increased as the angle gradually increases until the connecting component is activated. During the folding process, the creasing component simultaneously applies pressure to the cardboard box from the inside, facilitating rapid shaping. Simultaneously, the marking component rolls along the inside of the cardboard box to create a pre-fold line. This process avoids the problem of weak tensile strength in biodegradable cardboard when folded at small angles. The initial low pressure prevents material molecular chain breakage, and the high pressure at the end overcomes material resilience, thus improving the bending effect. Furthermore, the progressive pre-compression creates a crease memory effect, causing directional deformation of the fiber structure during the final fold, reducing the breakage rate. The formed curved creasing disperses stress through its gradually changing curvature, protecting the integrity of the material fibers and further enhancing the material's integrity, thereby improving the device's practicality.

[0014] In this invention, the combined use of components such as the driving component and the unloading component reduces the initial force applied to the cardboard box, avoiding the problem of weak tensile strength of biodegradable cardboard when folded at small angles. It can prevent the material molecular chain from breaking through the initial low pressure, and increase the applied force as the angle gradually increases, so that the material's elasticity can be overcome by high pressure at the end, thereby improving the bending effect. At the same time, the progressive pre-compression forms a crease memory effect, causing the fiber structure to deform in a directional manner during the formal folding, thereby reducing the breakage rate. In this invention, by using connecting components and other parts in cooperation, it is easier to perform auxiliary bending from the inside of the cardboard box bending point and simultaneously perform creasing treatment when the bending angle is too large, thereby improving the practicality of this device.

[0015] In this invention, by using components such as the indentation assembly and the marking assembly in combination, a curved indentation is formed. The gradual curvature of the indentation disperses stress, thereby protecting the integrity of the material fibers and further protecting the integrity of the material, thus improving the practicality of the device.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1 to 10 The present invention provides a technical solution: a biodegradable and environmentally friendly paper box folding packaging device, including a lifting worktable 1, with symmetrical driving components 2 for folding on both sides of the lifting worktable 1, a force-relieving component 3 on the driving component 2, a connecting component 5 on the side end of the force-relieving component 3, an indentation component 8 for marking above the connecting component 5, and an marking component 9 on one side of the indentation component 8.

[0020] In this embodiment, as Figures 1 to 5As shown, the drive assembly 2 includes an L-shaped drive frame 21 located above the lifting worktable 1. The top of the L-shaped drive frame 21 is provided with symmetrically arranged support frames 22. A rotating seat 23 is connected between the two support frames 22. A rotating shaft 24 is rotatably connected to one side of the rotating seat 23. One end of the rotating shaft 24 is rotatably engaged with the adjacent support frame 22. A drive motor 25 is provided on the outside of the support frame 22. The output end of the drive motor 25 is connected to the end of the rotating shaft 24. A linkage arm 26 is symmetrically arranged on the rotating shaft 24 and is located on both sides of the rotating seat 23. The other end of the two linkage arms 26 is connected to an L-shaped connecting frame 27. The L-shaped connecting frame 27 is connected to the tail of a telescopic arm 28. The telescopic end of the telescopic arm 28 is connected to a limiting frame 29. The unloading assembly 3 includes an unloading frame 31 disposed between two linkage arms 26. The bottom of the unloading frame 31 has a sliding groove 32, and a resistance block 33 is slidably disposed in the sliding groove 32. The bottom of the resistance block 33 is hinged to a telescopic rod 34, and the tail of the telescopic rod 34 is hinged to a fixed frame 35 on the L-shaped drive frame 21. Symmetrical resistance grooves 36 are provided on both sides of the resistance block 33. A resistance wedge block 37 is slidably engaged in each resistance groove 36. The side end of the resistance wedge block 37 is movably connected to the inner wall of the resistance groove 36 through a compression spring 38. The obliquely disposed side of the resistance wedge block 37 abuts against the obliquely disposed side of the resistance wedge frame 39 at the bottom of the unloading frame 31. The resistance wedge block 37 and the resistance wedge frame 39 are slidably engaged with each other. The resistance wedge block 37 has an L-shaped contact frame 40 on its side end. The two L-shaped contact frames 40 are arranged symmetrically. The unloading frame 31 has a mating groove 41 in the middle. A trigger rod 42 is slidably arranged in the mating groove 41. The end of the trigger rod 42 is movably connected to the inner wall of the mating groove 41 through a spring telescopic rod 43. Control wedge blocks 44 are symmetrically arranged on both sides of the trigger rod 42. The end of the L-shaped contact frame 40 abuts against the side of the control wedge block 44 that is inclined to the side. The operator controls the drive motor 25 to rotate the rotating shaft 24 and the linkage arm 26 on the rotating seat 23, which facilitates the folding of the cardboard box via the L-shaped connecting frame 27 and the limiting frame 29. In the initial folding stage, the force of the folding, under the action of the telescopic rod 34, causes the resistance block 33 to slide along the sliding groove 32. This causes the two resistance wedge blocks 37 to cooperate with the resistance wedge frame 39, and under the action of the compression spring 38, slide along the resistance groove 36, thus dispersing the folding force. During the movement of the two resistance wedge blocks 37, the cooperation between the L-shaped contact frame 40 and the control wedge block 44 compresses the trigger rod 42, which, under the action of the spring telescopic rod 43, slides along... As the sliding groove 41 slides outward, and the resistance block 33 moves to the side of the sliding groove 32, the resistance block 33 stops sliding, the compression spring 38 contracts to its maximum, and the flipping force is directly applied to the unloading frame 31 on the linkage arm 26, thereby restoring the flipping force. This reduces the initial force applied to the cardboard box, avoiding the problem of weak tensile strength of biodegradable cardboard when folded at a small angle. It can prevent the material molecular chain from breaking through the initial low pressure, and increase the applied force as the angle gradually increases, so that it can overcome the material's elasticity through high pressure at the end, thereby improving the bending effect. At the same time, the progressive pre-compression forms a crease memory effect, causing the fiber structure to deform in an oriented manner when folded, thereby reducing the breakage rate.

[0021] In this embodiment, as Figures 5 to 8 As shown, the connecting assembly 5 includes a connecting block 51 disposed on the side of the unloading frame 31 away from the sliding groove 32. The side end of the connecting block 51 slides vertically with the side end of the unloading frame 31. The side end of the connecting block 51 is obliquely positioned. When the resistance block 33 slides along the sliding groove 32 and is limited, the trigger rod 42 can act on the obliquely positioned side of the connecting block 51. The side end of the connecting block 51 is provided with a pulling frame 52. The side of the pulling frame 52 away from the connecting block 51 is provided with an opening 53. A sliding sleeve 54 is provided in the opening 53. Each end of the pulling frame 52 is provided with a fitting rod 55. The fitting rod 55 is located in the annular groove 56 on the sliding sleeve 54. The sliding sleeve 54 is vertically slidably connected to the power rod 57. The bottom of the power rod 57 is rotatably connected to the auxiliary frame 58. The side end of the auxiliary frame 58 is connected to the inner wall of the linkage arm 26 on the adjacent side. The bottom of the sliding sleeve 54 is movably connected to the top of the auxiliary frame 58 through the telescopic spring 59. The top two sides of the sliding sleeve 54 are symmetrically hinged with hinge rods 60. The other end of the hinge rod 60 is hinged to the side end of the abutment block 61. The abutment block 61 is slidably arranged in a connecting groove 63 in the H-shaped frame 62 at the top of the power rod 57. The bottom of the power rod 57 is connected to the middle of the linkage bevel gear 64. The side end of the linkage bevel gear 64 is engaged with an auxiliary bevel gear 65. The included angle between the auxiliary bevel gear 65 and the linkage bevel gear 64 is set at 90 degrees. The center of the auxiliary bevel gear 65 is rotatably connected to the linkage arm 26 through an auxiliary shaft 66. A first transmission belt 67 is sleeved on the outside of the auxiliary shaft 66. The other end of the first transmission belt 67 is sleeved on the outside of the rotating shaft 24. A bracket 68 is provided on the unloading frame 31. A rotating sleeve 70 is rotatably connected to the bracket 68 through a transmission shaft 69. The rotating sleeve 70 covers the outside of the H-shaped frame 62. When the resistance block 33 abuts against the inner wall of the sliding groove 32, the trigger rod 42 and the bottom of the connecting block 51 cooperate with each other, thereby driving the connecting block 51 to move upward. Then, the pulling frame 52 moves upward synchronously. With the cooperation of the fitting rod 55 and the annular groove 56, the sliding sleeve 54 moves upward along the power rod 57, thereby driving the telescopic spring 59 to stretch. Under the action of the hinge rod 60, the two abutting blocks 61 slide away from each other along a connecting groove 63 on the H-shaped frame 62 and abut against the rotating sleeve 70. The inner wall, driven by the rotating shaft 24 and the first transmission belt 67, drives the auxiliary shaft 66 to deflect synchronously. Then, with the cooperation of the auxiliary bevel gear 65 and the linkage bevel gear 64, the power rod 57 and the sliding sleeve 54 rotate synchronously. Through the contact block 61, the rotating sleeve 70 and the transmission shaft 69 rotate, driving the creasing assembly 8 and the marking assembly 9 to work synchronously. This facilitates auxiliary bending and simultaneous creasing from the inside of the cardboard box when the bending angle is too large, thereby improving the practicality of the device.

[0022] In this embodiment, as Figures 8 to 10 As shown, the indentation assembly 8 includes a transmission frame 81 located at the top of the limiting frame 29. The bottom of the transmission frame 81 is provided with a linkage shaft 82. A second transmission belt 83 is sleeved on the linkage shaft 82. The other end of the second transmission belt 83 is sleeved on the top of the transmission shaft 69. The transmission shaft 69 is rotatably engaged with the tail of the telescopic arm 28. The bottom of the linkage shaft 82 is connected to one end of the transmission crank 84. The other end of the transmission crank 84 is hinged to the end of the auxiliary crank 85. The other end of the auxiliary crank 85 is hinged to the top of the sliding seat 86. The sliding seat 86 is slidably engaged with the top of the limiting frame 29. A control spring rod 87 is provided at the side end of the second transmission belt 83. The output end of the control spring rod 87 is connected to the locking sleeve 88. The locking sleeve 88 is locked at the side end of the second transmission belt 83. The marking component 9 includes a control bevel gear 92 that is obliquely rotatably disposed in the connecting groove 91 of the sliding seat 86. The bottom of the control bevel gear 92 meshes with the tooth groove end of the drive tooth groove rod 93. The drive tooth groove rod 93 is disposed in the mounting groove 94 at the top of the limiting frame 29. A sliding rail 95 is provided on one side of the limiting frame 29. A marking element 96 is slidably fitted in the sliding rail 95. The side end of the marking element 96 is connected to the side end of the sliding seat 86. An arc-shaped cam 97 is rotatably connected to the side of the marking element 96 away from the limiting frame 29. An auxiliary transmission belt 98 is sleeved on the outer side of the rotatable connection of the arc-shaped cam 97. The other end of the auxiliary transmission belt 98 is sleeved on the rotatable connection between the control bevel gear 92 and the sliding seat 86. When the drive shaft 69 rotates, it drives the linkage shaft 82 to rotate via the second drive belt 83. Through the cooperation of the drive crank 84 and the auxiliary crank 85, the sliding seat 86 is driven to reciprocate along the limiting frame 29. During the folding of the cardboard box, the telescopic arm 28 is controlled to work in conjunction with the cardboard box forming. During the operation of the telescopic arm 28, the cooperation between the spring rod 87 and the locking sleeve 88 is controlled to keep the second drive belt 83 stably transmitting power on the linkage shaft 82 and the drive shaft 69. Through the cooperation between the bevel gear 92 and the drive toothed rod 93, the arc-shaped cam 97 is driven by the auxiliary drive belt 98 to roll along the bending point on the inside of the cardboard box to make indentations. With the cooperation of the sliding seat 86, it reciprocates to form a curved indentation. The gradual curvature of the indentation disperses stress, thereby protecting the integrity of the material fibers and further protecting the integrity of the material, thus improving the practicality of the device.

[0023] In this embodiment, as Figures 1 to 10 The method of using the biodegradable and environmentally friendly paper box folding packaging device, as shown, includes the following steps: S1: The operator controls the drive motor 25 to rotate the rotating shaft 24 and the linkage arm 26 on the rotating seat 23, which facilitates the folding of the cardboard box through the L-shaped connecting frame 27 and the limiting frame 29. In the initial stage of folding, the force of folding causes the resistance block 33 to slide along the sliding groove 32 under the action of the telescopic rod 34. This causes the two resistance wedge blocks 37 to cooperate with the resistance wedge frame 39 and slide along the resistance groove 36 under the action of the compression spring 38, thereby dispersing the folding force. During the movement of the two resistance wedge blocks 37, the L-shaped contact frame 40 cooperates with the control wedge block 44 to squeeze the trigger rod 42 to slide outward along the mating groove 41 under the action of the spring telescopic rod 43. After the resistance block 33 moves to the side of the sliding groove 32, the resistance block 33 stops sliding, the compression spring 38 contracts to its limit, and the folding force will directly act on the unloading frame 31 on the linkage arm 26, thereby restoring the folding force. S2: When the resistance block 33 abuts against the inner wall of the sliding groove 32, the trigger rod 42 and the bottom of the connecting block 51 cooperate with each other, thereby driving the connecting block 51 to move upward, and then the pulling frame 52 moves upward synchronously. Under the cooperation of the fitting rod 55 and the annular groove 56, the sliding sleeve 54 moves upward along the power rod 57, thereby driving the telescopic spring 59 to stretch. Under the action of the hinge rod 60, the two abutting blocks 61 slide away from each other along a connecting groove 63 on the H-shaped frame 62 and abut against the inner wall of the rotating sleeve 70. Under the action of the rotating shaft 24 and the first transmission belt 67, the auxiliary shaft 66 is driven to deflect synchronously. Then, under the cooperation of the auxiliary bevel gear 65 and the linkage bevel gear 64, the power rod 57 and the sliding sleeve 54 rotate synchronously. Through the abutting block 61, the rotating sleeve 70 and the transmission shaft 69 rotate, driving the indentation assembly 8 and the marking assembly 9 to work synchronously. S3: When the drive shaft 69 rotates, it drives the linkage shaft 82 to rotate via the second drive belt 83. Through the cooperation of the drive crank 84 and the auxiliary crank 85, the sliding seat 86 is driven to reciprocate along the limit frame 29. During the folding of the cardboard box, the telescopic arm 28 is controlled to work in conjunction with the cardboard box forming. During the operation of the telescopic arm 28, the cooperation between the spring rod 87 and the locking sleeve 88 is controlled to keep the second drive belt 83 stably transmitting power on the linkage shaft 82 and the drive shaft 69. Through the cooperation between the bevel gear 92 and the drive toothed rod 93, the arc-shaped cam 97 is driven by the auxiliary drive belt 98 to roll along the fold on the inner side of the cardboard box to make indentations, and reciprocates with the cooperation of the sliding seat 86.
