Description
Technical Field
[0001] This utility model relates to the technical field of corrugated cardboard processing equipment, specifically a corrugated cardboard flattening and slotting machine. Background Technology
[0002] Corrugated cardboard, as a crucial basic material in the packaging industry, directly impacts the forming accuracy and compressive strength of cartons through its processing quality. On corrugated cardboard production lines, flattening and slotting are two key processes: flattening eliminates wave deformation during conveying and stacking, while slotting provides accurate fold line positions for subsequent folding. However, existing flattening and slotting equipment generally suffers from the following technical problems.
[0003] First, the motion structure of traditional flattening devices has poor stability. Existing equipment mostly uses a fixed base structure, and the movement of the flattening components usually relies on manual adjustment or simple roller support. This structure causes the corrugated cardboard to easily shift or tilt during flattening and feeding, resulting in uneven indentation and guiding deviations. While some improved structures have added guide rails or limiting components, their overall rigidity is insufficient to guarantee stable guidance during high-speed operation. Especially when processing long or heavy cardboard, the equipment vibrates significantly, positioning accuracy decreases, and the pressing quality is affected.
[0004] Secondly, traditional corrugated cardboard slotting devices have a simple structure and limited control precision. Most existing equipment uses a fixed cutter head or direct-drive motor structure, which cannot achieve flexible adjustment of the slotting depth. When the thickness or material of the cardboard changes, the operator needs to manually adjust the cutter position, which is not only cumbersome but also prone to causing inconsistent slotting depths or curved cuts. In addition, the fixed motor structure is prone to vibration accumulation after long-term high-speed operation, leading to problems such as gear wear and cutline misalignment, which seriously affects processing accuracy and product consistency.
[0005] In view of this, we have studied and improved the existing problems to provide a corrugated cardboard flattening and slotting machine to solve the current problems. The aim of this technology is to solve the problems and improve its practical value. Utility Model Content
[0006] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.
[0007] Therefore, the technical solution adopted by this utility model is: a corrugated cardboard flattening and slotting machine, including a motion seat, a pressing seat and a slotting component.
[0008] The motion seat serves as the load-bearing foundation for the entire machine, supporting and guiding its smooth operation. The pressure seat is positioned above the motion seat to flatten the corrugated cardboard. The slotting assembly is located above the motion seat and uses an electronically controlled drive to precisely slot the corrugated cardboard.
[0009] Through the above structural combination, the whole machine can perform cardboard conveying, flattening and slotting while having good mechanical coordination and dynamic stability.
[0010] In a preferred example, the surface of the motion seat is provided with a moving component, which includes a drive wheel and a motor structure. The motor drives the drive wheel to roll via a transmission shaft, thereby realizing the parallel movement of the motion seat.
[0011] With this design, the motion seat can move freely along the ground trajectory, and with the help of the automatic control system, it can achieve precise displacement, so that the corrugated cardboard can maintain a stable feed during the flattening and grooving process.
[0012] Specifically, this motion structure improves the continuity and positioning accuracy of cardboard feeding, and reduces manual intervention and guiding errors.
[0013] In a preferred example, a counterweight compartment is provided on the surface of the motion seat, and an adjustable counterweight module is installed inside the counterweight compartment. This module can be moved in position or its weight increased or decreased according to the thickness, density, and flattening force requirements of the cardboard, thereby achieving precise adjustment of the machine's center of gravity.
[0014] Specifically, this structure can effectively improve the problem of unstable operation caused by eccentric loading in traditional equipment, and enable the whole machine to maintain the balance of the structural center of gravity during high-speed flattening and grooving, significantly improving motion stability and pressing consistency.
[0015] In a preferred example, pressure edges are fixedly installed on both sides of the motion seat, and the pressure edges are arranged along the length of the motion seat to limit the lateral offset of the corrugated cardboard.
[0016] Specifically, the pressing edge forms a mechanical limiting and guiding channel during the movement of the cardboard, ensuring that the corrugated cardboard is always on the processing center line, thereby avoiding the problem of slotting position deviation caused by skewing and improving the overall guiding accuracy and processing consistency.
[0017] In a preferred example, several counterweights are detachably mounted on the surface of the pressure base, and can be quickly replaced via threaded fastening or pin positioning. The operator can flexibly adjust the number and arrangement of the counterweights according to the cardboard thickness and flattening requirements to control the clamping force.
[0018] In addition, the bottom surfaces of the pressure seat and the pressure edge are equipped with several sliding rollers. The sliding rollers are made of wear-resistant rubber-coated structure, with rolling bearings embedded inside, and the outer ring is installed in conjunction with the guide groove.
[0019] Specifically, this structure can provide uniform pressure and reduce frictional resistance during the flattening process, effectively preventing scratches or indentations on the cardboard surface and ensuring the flatness and processing accuracy of the cardboard.
[0020] In a preferred example, the slotted assembly includes a boom, a servo motor, and an external rotor motor fixed to the front end of the boom. One end of the boom is hinged to the motion seat via a pivot, and the other end is fixedly mounted with the external rotor motor; the middle of the boom is provided with transmission teeth that mesh with the gear at the output end of the servo motor.
[0021] The servo motor is fixedly mounted on the surface of the motion seat. When the servo motor outputs torque, it drives the boom arm to swing up and down around the hinge point through the transmission gear, thereby driving the external rotor motor to achieve changes in the vertical angle.
[0022] Specifically, this linkage structure can precisely adjust the grooving angle and depth according to the thickness of the cardboard or the required groove depth, thus achieving a controllable and flexible grooving function.
[0023] In a preferred example, a slotted gear is fixedly fitted onto the surface of the external rotor motor. This gear is made of high-strength alloy or tungsten-plated steel, which provides excellent wear resistance and cutting stability. When the servo motor drives the boom to swing, the external rotor motor drives the slotted gear to perform linear rotary cutting along the direction of cardboard movement, thereby forming continuous, smooth, and uniformly deep grooves on the cardboard.
[0024] Specifically, this cutting system can adapt to corrugated cardboard of different thicknesses and densities, ensuring neat cuts and smooth grooves, avoiding tearing, and improving grooving quality and yield.
[0025] The beneficial effects achieved by this utility model are as follows: 1. In this utility model, by setting a moving component and a counterweight chamber on the moving seat, and installing pressure edges on both sides, the entire machine can achieve smooth forward and backward movement and automatic guidance during operation, ensuring that the corrugated cardboard maintains a stable feeding trajectory during flattening and slotting. This structure not only improves the straightness and repeatability of cardboard conveying, but also, through the adjustable counterweight module inside the counterweight chamber, makes the overall center of gravity of the equipment more balanced, significantly improving operational stability and pressing consistency.
[0026] 2. In this utility model, the grooving assembly consists of a boom, a servo motor, and an external rotor motor. Through the meshing of transmission gears with the servo motor, precise control is achieved to move the boom up and down, driving the external rotor motor. This structure, combined with the grooving gear driven by the external rotor motor, enables high-precision grooving of corrugated cardboard, resulting in consistent groove depth and smooth tangential lines, significantly improving processing accuracy and production efficiency.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0030] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.
[0031] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a corrugated cardboard flattening and slotting machine.
[0032] Combination Figures 1-5 As shown, the present invention provides a corrugated cardboard flattening and slotting machine, which includes a motion seat 100, a pressing seat 200, and a slotting component 300.
[0033] The motion seat 100 is an integral frame structure used to support the moving parts of the entire machine. Its surface is equipped with a moving component 110, which drives the motion seat 100 to move along the production line direction, thereby realizing the transfer of corrugated cardboard between slotting stations. Pressure edges 130 are fixedly installed on both sides of the motion seat 100. The pressure edges 130 are used to limit the lateral position of the cardboard, ensuring that the corrugated cardboard remains parallel during feeding and slotting processes, preventing deviation.
[0034] The surface of the motion seat 100 is provided with a counterweight compartment 120 for arranging adjustable counterweight modules to balance the center of gravity of the overall mechanism. The pressure seat 200 is detachably mounted above the motion seat 100, and its surface is equipped with several counterweight blocks 210 to provide clamping force to flatten the cardboard surface. The bottom surface of the pressure seat 200 and the bottom surface of the pressure edge 130 are both provided with several sliding rollers 220. The sliding rollers 220 are supported on the corrugated cardboard and are used to reduce friction during clamping and movement, maintaining stable and smooth guiding characteristics.
[0035] The grooving assembly 300 is disposed above the motion base 100 and includes a boom 310, a servo motor 320, and an external rotor motor 330 fixed to the front end of the boom 310. The rotor portion of the external rotor motor 330 is exposed, and a grooving gear 340 is fixedly sleeved on the rotating shaft for precise linear grooving of the corrugated cardboard. One end of the boom 310 is hinged to the motion base 100 via a rotating shaft, and its end is provided with a transmission gear 311 that meshes with the output gear of the servo motor 320. The servo motor 320 is fixedly mounted on the surface of the motion base 100 and drives the boom 310 to swing up and down through angle control, causing the external rotor motor 330 to drive the grooving gear 340 to move up and down, thereby achieving grooving adjustment at different depths.
[0036] In this embodiment, the moving component 110 includes a drive wheel assembly and a motor structure. The motor output is connected to the drive wheel shaft. By controlling the motor's direction and speed, the moving seat 100 can move in both directions. The drive wheels can be made of high-friction, wear-resistant rubber material, forming a friction drive with the ground rail surface, enabling the entire machine to run smoothly along the production line direction.
[0037] Specifically, the moving component 110 enables automatic feeding and precise positioning, ensuring synchronization between the slotting machine and the cardboard conveyor line and improving continuous operation efficiency.
[0038] In a preferred embodiment, the counterweight chamber 120 is equipped with an adjustable counterweight module, which can be moved or replaced to adjust the overall center of gravity. This structure can dynamically optimize the pressing balance according to the changes in cardboard thickness, density, and slotting force, thereby making the flattening and slotting process more stable and avoiding indentations or cracks caused by uneven stress on the cardboard.
[0039] Specifically, this structure allows for adjustment of module positions during equipment debugging to ensure that the downward pressure of the pressure seat 200 is consistent with the center of gravity distribution of the motion seat 100, thereby ensuring the balance of high-precision repetitive pressing actions.
[0040] In this embodiment, the surface of the pressure base 200 is provided with multiple counterweights 210, which are installed by threaded fastening or pin positioning, and the clamping force can be quickly adjusted according to the thickness of the cardboard. The counterweights 210 adopt a modular design, which can be quickly replaced by the operator to adapt to corrugated cardboard of different thicknesses.
[0041] Several sliding rollers 220 are evenly distributed on the bottom surface of the pressure seat 200 and the pressure edge 130. The sliding rollers 220 are made of wear-resistant rubber and their rolling bearings are engaged with the sliding guide grooves at the bottom of the pressure seat 200. This structure can effectively disperse the pressure during pressing, reduce the friction between the cardboard and the pressure seat, prevent scratches on the surface, and keep the cardboard fed in a straight line.
[0042] Specifically, the slide roller 220 achieves dynamic support and shock absorption during the pressing process, significantly improving the pressing stability and the flatness of the cardboard surface.
[0043] In this embodiment, the slotted assembly 300 is the core structure of the entire machine, consisting of a boom 310, a servo motor 320, and an external rotor motor 330. The boom 310 is made of high-strength aluminum alloy, which is lightweight and has high rigidity; one end of it is hinged to the motion seat 100 via a rotating shaft, and the other end is fixed to the external rotor motor 330. A transmission gear 311 is provided in the middle of the boom 310, which meshes with the gear at the output end of the servo motor 320.
[0044] When the servo motor 320 receives the control signal, its output drives the transmission gear 311 to rotate, and the boom 310 swings up and down around the hinge point, causing the outer rotor motor 330 to move up and down accordingly, thus achieving precise control of the slotting depth. This mechanism has a compact structure, fast motion response, and high positioning accuracy.
[0045] The external rotor motor 330 drives the slotted gear 340 to rotate via high torque. The outer edge of the gear cuts grooves along the direction of paperboard movement. The slotted gear 340 is replaceable and is made of high-hardness alloy or tungsten-plated steel to ensure long-term cutting accuracy and wear resistance.
[0046] Specifically, the grooving component 300 features a lightweight structure, sensitive response, and controllable grooving depth, making it suitable for high-speed corrugated cardboard processing production lines.
[0047] Working principle: During operation, the motion seat 100 moves along the paperboard conveying direction via the moving assembly 110, while the pressure edge 130 and the sliding roller 220 together constrain and guide the paperboard. The counterweight chamber 120 and the counterweight block 210 provide stable downward pressure, ensuring that the paperboard remains flat throughout the movement.
[0048] When the servo motor 320 drives the boom 310 to swing, the external rotor motor 330 drives the slotting gear 340 to cut along the upper surface of the cardboard, realizing continuous slotting of the corrugated cardboard. Throughout the process, all components work in coordination, so that flattening and slotting are completed simultaneously, thereby significantly improving work efficiency and processing accuracy.
