Description

Technical Field

[0001] This invention relates to the field of corrugated cardboard box production technology, and in particular to a creasing process for corrugated cardboard box production. Background Technology

[0002] In the corrugated box manufacturing process, creasing (marking) is a core step that facilitates precise folding and shaping of the box. Traditional creasing processes generally use rigid creasing wheels to directly press the surface of the corrugated cardboard.

[0003] However, existing crimping processes have the following drawbacks:

[0004] Face paper bursting problem: In a dry production environment, when facing face paper with low humidity, high basis weight or recycled paper material, the violent stretching caused by rigid stamping can easily lead to the breakage of face paper fibers, resulting in the phenomenon of "bursting lines".

[0005] Corrugated structure strength damage: Rigid extrusion will indiscriminately crush the corrugated skeleton on both sides of the crease, resulting in a decrease in the edge crush strength and overall compression resistance of the carton.

[0006] Traditional humidification methods have limited effectiveness: Although some processes attempt to spray steam onto the surface of the cardboard before pressing, the moisture cannot quickly penetrate into the interlayer paper and core paper inside the corrugated cardboard, and excessive surface moisture may also cause the cardboard to warp and deform.

[0007] Therefore, a creasing process for corrugated cardboard box production needs to be designed to solve the above problems. Summary of the Invention

[0008] The purpose of this invention is to address the shortcomings of existing technologies by proposing a creasing process for corrugated carton production. This invention alleviates the bursting of the face paper, protects the strength of the corrugated structure, and improves the creasing forming accuracy by implementing needle-punching stress release, self-excited magnetic deep humidification, and synchronous guidance of the creasing trajectory before creasing.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A creasing process for corrugated cardboard box production uses a creasing device, which includes a workbench, a mounting frame, two sets of conveying components symmetrically arranged on the left and right sides of the workbench, two sets of roller conveying components for feeding and discharging cardboard on the workbench, a creasing component on the mounting frame, two sets of needle punching components symmetrically arranged vertically, a humidifying component inside the needle punching components, and a position adjustment component on the workbench and the mounting frame.

[0011] Includes the following steps:

[0012] S1: The corrugated cardboard is fed into the worktable through the conveying assembly on one side, and the cardboard is continuously conveyed to the other side by the roller conveying assembly on one side.

[0013] S2: Control the two sets of symmetrically arranged needle punching components to perform a translational cyclical motion synchronized with the direction of cardboard movement, so that the needles on the needle punching components vertically penetrate into the inside of the cardboard; as the two sets of needle punching components approach and penetrate the cardboard, the humidification component pumps out moisture, and injects the moisture from the inside to the outside into the corrugated cardboard through the needles to locally soften it.

[0014] S3: After being needle-punched and humidified, the corrugated cardboard continues to move into the creasing assembly. The creasing wheel of the creasing assembly precisely presses against the prestressed guide line formed by the needles piercing the holes to complete the creasing process.

[0015] S4: After the creasing is completed, the corrugated cardboard is discharged from the roller conveyor and conveyor assembly on the other side.

[0016] In some possible implementations, the roller conveying assembly includes two horizontal shafts mounted on a mounting frame, each horizontal shaft having a material roller fixedly connected to it, and each horizontal shaft having meshing gears mounted on it. A first motor is mounted on the rear side of the mounting frame, and the end of the output shaft of the first motor is fixedly connected to one of the horizontal shafts.

[0017] In some possible implementations, the crimping assembly includes two first fixing brackets fixedly connected to the mounting bracket, two rotating shafts rotatably connected to adjacent sides of the two first fixing brackets, each of the two rotating shafts being provided with a crimping wheel, and the rotating shafts being connected to the corresponding horizontal shaft on the left side via a first transmission assembly.

[0018] In some possible implementations, the needle-punching assembly includes two second fixed frames fixedly connected to the mounting bracket. Each of the two second fixed frames is rotatably connected to a telescopic rod. The movable ends of the two telescopic rods are fixedly connected to a disc. The two telescopic rods are connected via a third transmission assembly. Each of the two discs is fixedly connected to a pin. A horizontal plate is sleeved on both pins. The lower end of the horizontal plate is fixedly connected to a plurality of needles. The needles on the two sets of needle-punching assemblies are staggered. The two telescopic rods on the right side are connected to the corresponding horizontal shaft via a fourth transmission assembly.

[0019] In some possible implementations, the humidification assembly includes piston chambers disposed within the two horizontal plates, each piston chamber having a magnetic plate slidably connected in a sealed manner, the adjacent sides of the two magnetic plates being attracted by opposite magnetic poles, and the two magnetic plates being elastically connected to the inner wall of the piston chamber by springs.

[0020] The adjacent side spaces of the two piston chambers are connected by air inlet pipes. The needle is hollow inside and has multiple air outlet holes on its outer wall. The piston chamber and the inside of the needle are connected by an air outlet channel. Both the air inlet pipe and the air outlet channel are equipped with one-way valves.

[0021] In some possible implementations, the outer wall of the needle is provided with a plurality of venting grooves extending axially. In step S, when the needle injects moisture into the interior of the cardboard, excess gas inside the cardboard is discharged outward through the venting grooves to relieve pressure.

[0022] In some possible implementations, the position adjustment assembly is mounted on a worktable and a mounting bracket, and includes a slide rail and a threaded rod. A movable block is slidably connected to the slide rail, and the movable block is threadedly connected to the threaded rod. Two limit blocks and a U-shaped block are fixedly connected to the movable block.

[0023] The U-shaped block is used to push the disc to move axially, and the limiting block is used to push the pressure wheel to move axially.

[0024] In some possible implementations, the first rotating shaft is provided with a keyway, and the inner wall of the pressure wheel is provided with a key block that slides with the keyway;

[0025] The two threaded rods are connected by a second transmission assembly. A gearbox and a second motor are mounted on the mounting bracket. The output shaft of the second motor is fixedly connected to the input shaft of the gearbox. The threaded rod located above is fixedly connected to the output shaft of the gearbox. The two threaded rods are mounted on the mounting bracket and the worktable through bearing seats.

[0026] The present invention has the following beneficial effects:

[0027] 1. Synergistic effect of physical stress release and internal softening: By pre-punching micropores with needles, the continuous tensile stress of the face paper is broken; combined with the high concentration of warm and humid air injected into the needles, instantaneous deep softening of the corrugated cardboard is achieved, which helps to reduce the bursting rate and reduce the loss of edge crush strength.

[0028] 2. Motion matching and damage prevention: The rigid synchronous drive of the transmission chain matches the horizontal speed of the needle during the insertion and withdrawal phases with the speed of the cardboard conveyor. From a kinematic perspective, this reduces the relative slippage between the needle and the cardboard, which helps to reduce the pulling and scratching of the needle on the cardboard and helps to ensure the repeatability and stability of the process.

[0029] 3. Precise humidification: When the upper and lower horizontal plates are close together, the magnetic plates attract each other and compress the piston chamber. This achieves a physical and continuous coordination of "pressurizing air when close and humidifying when inserted" without the need for a complex air pump control valve. The humidification action and the needle insertion action are linked in time and space, which can reduce the problem of misalignment between humidity application and needle insertion position in traditional timed spraying methods.

[0030] 4. Anti-bulging and pressure relief protection: The outer wall of the needle has an axial venting groove. After the injected high-pressure moisture softens the fiber, it can be released outward through the venting groove, which helps to prevent high-pressure gas from causing adverse expansion damage to the corrugated cavity. At the same time, the presence of the venting groove promotes the uniform diffusion of moisture inside the cardboard, which helps to improve the spatial consistency of local softening.

[0031] 5. Coaxial linkage integration of position adjustment: The position adjustment component drives the axial displacement of the needle punching component and the pressing component simultaneously through the U-shaped block and the limit stop on the same moving block. This reduces the cumulative error caused by independent adjustment of multiple components and helps to ensure high-precision overlap between the prestressed guide line and the pressing wheel trajectory under different production specifications.

Detailed Implementation

[0041] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0042] This embodiment provides a creasing process for corrugated cardboard box production, using a creasing device. For example... Figures 2 to 8 As shown, the creasing equipment includes a worktable 200, a mounting frame, two sets of conveying assemblies 100 symmetrically arranged on the left and right sides of the worktable 200, two sets of roller conveying assemblies for feeding and discharging paperboard on the worktable 200, creasing assemblies on the mounting frame, two sets of needle punching assemblies symmetrically arranged vertically, a humidifying assembly disposed inside the needle punching assembly, and a position adjusting assembly disposed on the worktable 200 and the mounting frame.

[0043] like Figures 2 to 4 As shown, two sets of conveying components 100 are symmetrically assembled on the left and right sides of the workbench 200, which are used to smoothly guide the corrugated cardboard to be processed and to export the cardboard that has been crimped. Two sets of roller conveying components are assembled on the workbench 200, located at the feeding end and the discharging end of the crimping line, respectively.

[0044] The roller conveyor assembly includes two horizontal shafts mounted on a mounting frame. Each horizontal shaft is fixedly connected to a material roller 201, and each horizontal shaft is equipped with meshing gears 202. A first motor 203 is fixedly mounted on the rear side of the mounting frame. The output shaft of the first motor 203 is fixedly connected to one of the horizontal shafts. The first motor 203 drives the horizontal shafts and the material rollers 201 to rotate. Through the transmission of the gears 202, the upper and lower material rollers 201 continuously and smoothly clamp and push the corrugated cardboard. The meshing transmission of the gears helps to ensure that the linear speed of the upper and lower material rollers is consistent and there is no relative slippage, which helps to ensure the stability and positional accuracy of the cardboard conveying process.

[0045] like Figure 3As shown, the creasing assembly includes two first fixed frames 301 fixedly connected to the mounting frame. The adjacent sides of the two first fixed frames 301 are rotatably connected to two rotating shafts 302. Each rotating shaft 302 is equipped with a creasing wheel 303. The rotating shaft 302 is connected to the corresponding horizontal shaft on the feeding side through a first transmission assembly 305, realizing the synchronous rotation drive of the feeding roller and the creasing wheel 303, so that the linear speed of the creasing wheel 303 is matched with the paperboard conveying speed in real time.

[0046] The needle punching assembly is located in the preceding process of the crimping assembly. It includes two second fixed frames 502 fixedly connected to the mounting frame. Each of the two second fixed frames 502 is rotatably connected to a telescopic rod 503. The movable ends of the two telescopic rods 503 are fixedly connected to a disc 501. The two telescopic rods 503 are kept synchronously connected through a third transmission assembly 504. The two telescopic rods 503 located on the discharge side are connected to the corresponding horizontal shaft through a fourth transmission assembly 508 to ensure that the needle punching movement is synchronized with the power source for paperboard conveying.

[0047] Two discs 501 are eccentrically fixed with pins 505, and a horizontal plate 506 is fitted on both pins 505 to form a translational linkage structure. Multiple hollow needles 507 are fixedly connected to the lower end of the horizontal plate 506, and the needles 507 on the upper and lower needle-punching assemblies are staggered. Through a complete transmission chain consisting of the first transmission assembly 305, the third transmission assembly 504, the fourth transmission assembly 508, and the gear 202, the power of the first motor 203 is synchronously distributed to the roller conveying assembly, the crimping assembly, and the needle-punching assembly. When the discs 501 rotate, they drive the horizontal plate 506 and the needles 507 to perform translational cyclical motion. Under the rigid constraint of this transmission chain, the horizontal component speed of the needles 507 is always consistent with the horizontal movement speed of the paperboard during the entire movement stage of inserting into and withdrawing from the paperboard. This overall transmission layout realizes the vertical and stable insertion and extraction of the needles 507 into the paperboard, which can reduce the problem of tearing the paperboard face paper due to rotation or speed difference.

[0048] In addition, the needles 507 on the upper and lower needle punching components are staggered in the horizontal direction, so that the two rows of microholes formed by the upper and lower needles in the thickness direction of the paperboard intersect each other in the horizontal projection. This creates a denser stress release lattice in the creasing area than a single row of microholes. At the same time, it can reduce the tip collisions inside the paperboard when the upper and lower needles pierce each other. This helps to ensure that the needles can form a row of through or deeply interlaced microholes in the thickness direction of the paperboard. This is beneficial for breaking the continuous tensile stress in the face paper and core paper layers, and provides a more uniform prestress release guide for subsequent creasing.

[0049] like Figure 5 and Figure 7As shown, the humidification component is integrated inside the acupuncture component. The humidification component includes piston chambers 602 opened inside two horizontal plates 506. Magnetic plates 603 are slidably connected to both piston chambers 602. The magnetic poles of the two magnetic plates 603 are opposite on adjacent sides, and the magnetic plates 603 are elastically connected to the inner wall of the piston chambers 602 by springs 604.

[0050] Both adjacent spaces of the two piston chambers 602 are connected to air inlet pipes 601. The needle 507 is hollow inside, and its outer wall has multiple air outlet holes 606. The piston chambers 602 and the interior of the needle 507 are connected through an air outlet channel 605. Both the air inlet pipe 601 and the air outlet channel 605 are equipped with one-way valves. Moisture enters the space of the piston chamber 602 near the cardboard through the air inlet pipe 601, and the moisture in the space of the piston chamber 602 near the cardboard passes through the air outlet. Channel 605 discharges in one direction. When the upper and lower horizontal plates 506 rotate with the disc 501 and approach each other, the magnetic attraction between the two magnetic plates 603 increases and overcomes the resistance of the spring 604 to attract each other, compressing the piston chamber 602 and forcing the warm and humid air through the air outlet channel 605 into the needle 507, and injecting it into the cardboard through the air outlet 606. When the horizontal plates 506 separate, the magnetic force weakens, and the magnetic plates 603 reset under the action of the spring 604 and automatically draw in the moisture through the air inlet pipe 601.

[0051] The specific working process is as follows: When the upper and lower horizontal plates 506 move closer to each other as the disc 501 rotates, the magnetic attraction between the two magnetic plates 603 increases as the distance decreases, overcoming the resistance of the spring 604 and attracting each other. This compresses the closed air chamber of the piston chamber 602 near the cardboard, increasing the pressure inside the air chamber. The pre-stored warm and humid air is then forced into the hollow needle 507 through the air outlet channel 605 and injected into the cardboard through multiple air outlet holes 606 on the outer wall of the needle 507. When the horizontal plates 506 move further away from each other as the disc 501 continues to rotate, the distance between the magnetic plates 603 increases, the magnetic attraction weakens, and the magnetic plates 603 move back under the reset action of the spring 604. A negative pressure is formed in the space of the piston chamber 602 near the cardboard, and the one-way valve on the air inlet pipe 601 opens, drawing external warm and humid air into the piston chamber 602 to complete the air replenishment. Meanwhile, the one-way valve on the air outlet channel 605 remains closed under negative pressure, which helps prevent backflow.

[0052] In addition, the outer wall of the needle 507 is provided with multiple venting grooves 607 extending axially. While the needle 507 injects high-pressure moisture into the paperboard to soften it, the gas originally stored inside the paperboard and the excess gas generated during the injection process can be smoothly released outward along the axial channel formed by the venting grooves 607. This helps to prevent local high-pressure gas from causing irreversible expansion damage to the arched structure of the corrugated core paper. At the same time, during the pressure release process, the venting grooves 607 guide the moisture to form a directional micro-circulation airflow along the needle axis inside the paperboard, which promotes the uniform diffusion of moisture between the face paper, core paper and liner paper in the creasing area, and can reduce local over-wetting or uneven softening.

[0053] like Figure 4 and Figure 6 As shown, the position adjustment component is set on the workbench 200 and the mounting frame to adapt to the creasing position requirements of different specifications of cardboard. The position adjustment component includes a slide rail 406 and a threaded rod 401. A moving block 407 is slidably connected to the slide rail 406. The moving block 407 is threadedly connected to the threaded rod 401. Two limit blocks 409 and a U-shaped block 408 are fixedly connected to the moving block 407.

[0054] A keyway 304 is provided on the rotating shaft 302, and a key block is provided on the inner wall of the pressure wheel 303 to slide in cooperation with the keyway 304, so that the pressure wheel 303 can be driven to rotate by the rotating shaft 302 and can also slide along the axial direction. Two threaded rods 401 are connected by transmission through the second transmission assembly 403. A gearbox 405 and a second motor 404 are installed on the mounting bracket. The output shaft of the second motor 404 is connected to the input shaft of the gearbox 405, and the threaded rod 401 above is connected to the output shaft of the gearbox 405.

[0055] Specifically, when it is necessary to switch the cardboard processing specifications, the second motor 404 starts, driving the upper and lower threaded rods 401 to rotate synchronously via the gearbox 405 and the second transmission assembly 403. The rotational motion of the threaded rods 401 is converted into the linear translation of the moving block 407 along the slide rail 406. During the translation, the U-shaped block 408 fixedly connected to the moving block 407 pushes the disc 501 to slide axially along the telescopic rod 503, thereby causing the entire needle punch assembly to change its axial position; at the same time, the limiting block 409 fixed on the same moving block 407 synchronously pushes the pressure wheel 303 to slide axially along the keyway 304 on the rotating shaft 302.

[0056] Among them, the first transmission component 305, the second transmission component 403, the third transmission component 504 and the fourth transmission component 508 are all chain and sprocket drives.

[0057] The specific crimping process of this invention is as follows:

[0058] According to the creasing position requirements of the corrugated cardboard to be processed, the second motor 404 is started, which drives the upper and lower threaded rods 401 to rotate synchronously through the gearbox 405 and the second transmission assembly 403. The threaded rods 401 drive the moving block 407 to slide along the slide rail 406, which in turn pushes the disc 501 to move axially through the U-shaped block 408. At the same time, the limiting block 409 pushes the creasing wheel 303 to move axially along the keyway 304 on the rotating shaft 302, thus completing the axial alignment and coaxial linkage adjustment of the needle punching assembly and the creasing assembly.

[0059] like Figure 1 As shown, step S1: Cardboard feeding and smooth continuous conveying

[0060] The corrugated cardboard to be processed is fed into the worktable 200 through the conveyor assembly 100 on one side. The first motor 203 drives the feed roller 201 on the feeding side to rotate, clamping the cardboard and smoothly and continuously conveying it to the other side at a set speed (120m / min-200m / min).

[0061] Step S2: Needle puncture and self-stimulating local softening with moisturizing

[0062] The first motor 203 drives the telescopic rod 503 and the disc 501 to rotate through the transmission mechanism, controlling the upper and lower sets of needle punching components to perform translational cyclical motion. During the process of the horizontal plate 506 driving the needles 507 to vertically penetrate the interior of the cardboard, the horizontal translation speed of the horizontal plate 506 is controlled to be consistent with the horizontal translation speed of the cardboard.

[0063] As the upper and lower sets of needle-punching components approach and penetrate the cardboard, the two magnetic plates 603 magnetically move towards each other, compressing the piston chamber 602. This forces high-concentration moisture with a relative humidity of 85%-95% and a temperature of 45℃-60℃ into the hollow needles 507 through the air outlet channel 605, and injects it into the corrugated cardboard from the inside out through the air outlet 606, achieving localized deep softening of the face paper and core paper in the creasing area. Excess gas is discharged and depressurized through the axial exhaust groove 607 on the outer wall of the needles 507, while the exhaust groove guides the moisture to diffuse evenly between the layers of the cardboard.

[0064] Step S3: Prestressing guidance and main compression molding

[0065] After being needle-punched and softened, the corrugated cardboard continues to move into the creasing assembly. Under the action of the needles 507 piercing the perforations in step S2, a physical prestress guide line composed of micro-perforations is formed in the creasing area of ​​the cardboard. This guide line releases the continuous tensile stress of the face paper on the creasing path in advance through the dense perforations. The creasing wheel 303 driven by the rotating shaft 302, under the synchronous drive of the transmission chain, precisely presses against the prestress guide line at a linear speed matching the speed of the cardboard, smoothly completing the creasing formation, which can effectively reduce face paper bursting and corrugation collapse.

[0066] Step S4: Finished product unloading

[0067] After the corrugated cardboard is creasing and forming, it continues to move horizontally and is smoothly discharged by the material roller 201 and conveying assembly 100 on the discharge side, completing the entire creasing process.

[0068] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
