[0002] The cardboard cutting line is a common processing step in the production process of the packaging industry. The technical performance of its processing equipment is directly related to the company's order delivery capabilities and resource utilization efficiency. The equipment currently used in the industry is designed based on the principle of mechanical transmission. The tool system and conveying mechanism adopt a fixed installation structure and rely on manual operation to complete parameter setting. During the production process, the operator needs to change the tool spacing by manually tightening the adjustment bolts according to the basic specifications of each batch of cardboard, and use mechanical fixtures to adjust the lateral span of the pulley group to match the width of the cardboard. This process involves the coordinated operation of multiple physical positioning links, which not only requires high experience from the operator, but also the adjustment accuracy is easily affected by human judgment errors. Summary of the invention

[0008] Furthermore, the transmission assembly of the longitudinal displacement actuator includes a ball screw pair and a driving servo motor. The ball screw pair is connected to the output end of the driving servo motor through a coupling, and its screw thread portion forms a motion coupling with the ball nut of the load-bearing unit.

When the longitudinal displacement actuator is set in multiple numbers, the linear guide rails of each actuator are arranged in parallel with the ball screw pair. The load-bearing unit is provided with a quick-change tool mounting base, which forms a detachable assembly connection with the processing tool.

[0009] Furthermore, the bearing base has multiple longitudinal displacement actuators, which are arranged in a mirror-symmetrical manner in the longitudinal direction within the same axial position range; the bearing unit of each longitudinal displacement actuator is independently equipped with a processing tool, and differentiated programming control of the tool position is achieved through an independent servo drive system, so that the tool density in a single axial position range is significantly increased and the movement is interference-free.

[0010] Furthermore, the pulley assembly includes a first linear guide and a second linear guide arranged in parallel with each other, wherein the first linear guide is provided with at least one group of axially displaceable sliding bases, and the sliding base is provided with at least one pulley; the second linear guide is provided with at least one axially displaceable wheel position adjustment mechanism, and the wheel adjustment mechanism includes an axially movable unit controlled by a driving device, a telescopic actuator arranged on the axially movable unit, and a driving insert connected to the end of the telescopic actuator; complementary interlocking structures are provided at corresponding positions of the sliding base and the driving insert to realize constraints during linkage displacement.

[0011] Furthermore, the first linear guide rail has a rectangular cross section, and in the working state, the radial load acting direction of the sliding base is orthogonal to the axial direction of the first linear guide rail, thereby forming a self-locking effect to maintain the position stability of the sliding base.

The operator does not need to manually screw the adjustment bolts and use mechanical fixtures to adjust the parameters such as the tool spacing and the horizontal span of the pulley one by one as in traditional equipment, which greatly reduces the dependence on the operator's experience, and effectively reduces the adjustment accuracy problems caused by human judgment errors, improves the efficiency and quality of cardboard cutting processing, and improves the overall production adaptability and stability of the equipment, thereby enhancing the company's order delivery capabilities and resource utilization efficiency in the packaging industry.

[0031] See attached Figure 1 and 2 This embodiment relates to a cardboard processing device, the overall structure of which is reasonably designed and the components cooperate with each other to achieve efficient and accurate cardboard processing. The device mainly includes a frame 1, a feeding mechanism 2, a belt conveyor mechanism 3, a processing tool assembly 4 and a controller (not shown in the drawings).

[0032] The frame 1, as the supporting body of the entire equipment, is welded with solid steel and has sufficient strength and stability to withstand various forces and loads during the operation of the equipment, thereby ensuring the stability of the equipment during long-term operation.

[0033] The feeding mechanism 2 installed on the frame 1 has a feeding platform 21 with a plane, which is composed of a plurality of horizontally arranged flat plates and has good flatness and wear resistance, and can ensure the stability of the cardboard during the feeding process.

[0034] At least two guide plates 22 are arranged opposite to each other on the feeding platform 21. At least the side surface of the guide plates 22 is smooth. The interval between the two guide plates 22 can be adjusted by an adjustment device. The adjustment device includes a screw nut mechanism arranged at the bottom of the guide plate 22. The position of the guide plate 22 can be changed by rotating the screw, so as to meet the feeding requirements of paperboards of different widths and ensure that the paperboards can accurately enter the subsequent processing area.

[0035] The belt conveying mechanism 3 is installed in the frame 1 and opposite to the feeding mechanism 2. Its conveying belt 31 is made of polymer plastic, has good flexibility and wear resistance, and can smoothly convey cardboard.

[0036] The belt conveying mechanism 3 has a plurality of pulleys 32 , which cooperate with the conveying belt 31 , and the spacing between adjacent pulleys 32 is adjusted by an adjustable pulley assembly.

[0037] See attached Figure 3 and 4 The pulley assembly includes a first linear guide 33 and a second linear guide 34 arranged in parallel with each other. The first linear guide 33 has a rectangular cross-section and is made of stainless steel with high precision and rigidity.

[0038] In the working state, the radial load acting direction of the sliding base 35 is orthogonal to the axial direction of the first linear guide rail 33 , thereby forming a self-locking effect to maintain the position stability of the sliding base 35 .

[0039] The first linear guide rail 33 is provided with at least one group of axially displaceable sliding bases 35, and the complementary interlocking structure between the sliding base 35 and the driving insert is a protrusion and a groove that cooperate with each other, wherein the protrusion is a guide rib with a trapezoidal cross-section, and the groove is a dovetail groove structure that matches it. This structural design enables precise linkage displacement between the sliding base 35 and the driving insert.

[0040] The second linear guide rail 34 is provided with at least one axially displaceable wheel position adjustment mechanism 45, which includes an axial movement unit 47 controlled by a driving device 46, a telescopic actuator 48 arranged on the axial movement unit 47, and a driving insert 49 connected to the end of the telescopic actuator 48.

[0041] The driving device 46 is a synchronous belt linear module, specifically including a motor fixed to the end of the second linear guide 34. The motor is connected to the end of the guide through a mounting seat, and its output shaft is coaxially driven with the driving synchronous pulley. The driving synchronous pulley and the driven synchronous pulley are respectively mounted on the two ends of the second linear guide 34 through bearing seats, and the axes of the two pulleys are parallel to the second linear guide 34. The synchronous belt is sleeved between the driving synchronous pulley and the driven synchronous pulley, and is rigidly connected to the axial moving unit through a synchronous belt pressure plate. The motor drives the synchronous belt to drive the axial moving unit to perform linear displacement along the second linear guide 34, thereby realizing precise adjustment of the spacing between adjacent pulleys 32 to meet the cardboard conveying needs under different processing requirements.

[0042] The belt conveyor mechanism 3 also includes a driven roller 36, which is installed in the frame 1 through a bearing seat and cooperates with the conveyor belt 31. Figure 7 The conveying belt 31 is driven to move by the rotation of the active roller 37 to realize the conveying of the cardboard. The driven roller 36 is made of steel or other suitable materials to ensure the tension and conveying stability of the conveying belt 31.

[0043] The processing tool assembly 4, which is also installed in the frame 1 and cooperates with the belt conveyor mechanism 3, is used to realize the slotting or slitting processing. Figure 5 and 6 The processing tool assembly 4 has at least one processing tool 41. The processing tool 41 is made of high-speed steel, has a sharp cutting edge and high hardness, and can accurately process the cardboard.

[0044] Driven by the machining tool assembly 4 , the machining tool 41 can achieve controllable displacement in both horizontal and vertical directions.

[0045] Specifically, the structure of the machining tool assembly 4 includes a bearing base 42, a lateral displacement mechanism 43 and at least one set of longitudinal displacement actuators 44. The bearing base 42 is a large cast iron base with good rigidity and stability. The longitudinal displacement actuator 44 is mounted on the bearing base 42, on which at least one machining tool 41 is arranged, and the longitudinal displacement actuator 44 includes a guide assembly, a bearing unit sliding along the guide assembly, and a transmission assembly 52 driving the bearing unit to reciprocate.

[0046] More specifically, the guide assembly 50 is a linear guide rail that cooperates with the carrying unit 0 and is made of high-precision alloy steel. When the longitudinal displacement actuator 44 is set in multiple numbers, the linear guide rails of each actuator are arranged in parallel with the ball screw pair, ensuring the stable movement of the carrying unit 0 in the longitudinal direction.

[0047] The transmission assembly 52 includes a ball screw pair and a driving servo motor. The ball screw pair is connected to the output end of the driving servo motor through a coupling. The threaded portion of the screw forms a motion coupling with the ball nut of the load-bearing unit. The longitudinal fine-tuning positioning of the load-bearing unit is achieved by controlling the speed and direction of the servo motor, thereby being able to accurately control the longitudinal position of the processing tool 41 to meet the requirements of different processing dimensions.

[0048] The lateral displacement mechanism 43 is configured in linkage with the bearing base 42 to achieve its linear displacement in the lateral direction. The lateral displacement mechanism 43 includes a rigid base 53 fixedly connected to the frame 1, and a linear guide rail arranged in the lateral direction is provided on its surface. The working surface of the guide rail forms a sliding pair with the bearing base 42 to ensure the smooth lateral movement of the bearing base 42. The cylinder 54 fixed to the side wall of the base 53 cooperates with the inclined groove guide block 56 provided on the bearing base 42 through the wedge-shaped slider 55 connected to the end of the piston rod. The cylinder drives the wedge-shaped slider 55 to move vertically relative to the bearing base 42, decomposing the vertical driving force into a horizontal thrust to achieve the lateral displacement of the bearing base 42.

[0049] The carrying unit 42 is provided with a quick-change tool mounting base, which forms a detachable assembly connection with the processing tool 41, so as to facilitate the rapid replacement of the tool according to different processing requirements during the processing, thereby improving the adaptability and working efficiency of the equipment.

[0050] In actual use, the cardboard to be processed is first placed on the feed platform 21, and the interval of the guide plate 22 on the feed mechanism 2 is adjusted so that the cardboard can accurately enter the conveying belt 31 of the belt conveyor mechanism 3. Then the controller is started, and the controller controls the belt conveyor mechanism 3 to start working, and the conveying belt 31 drives the cardboard to be conveyed forward. During the conveying process, according to the preset processing parameters, the controller controls the adjustment of the spacing between adjacent pulleys 32 to adapt to the width and processing requirements of the cardboard, so as to ensure the stability and accuracy of the cardboard during the conveying process. When the cardboard reaches the processing area, the controller controls the processing tool assembly 4 to start working, and the processing tool 41 is driven by the lateral displacement mechanism 43 and the longitudinal displacement actuator 44 to perform slotting or slitting processing according to the preset path and method. After the processing is completed, the controller controls the belt conveyor mechanism 3 to convey the processed cardboard to the discharge port, completing the entire processing process.

[0051] On the basis of the above structure, the present embodiment may have optional functions, specifically, it may complete the wire board slitting action. A slitting assembly 6 for realizing the slitting process is installed in the frame 1. The slitting assembly cooperates with the belt conveyor mechanism to realize relative movement with the cardboard when the cardboard is transported via the belt conveyor mechanism, thereby completing the slitting process. The slitting assembly 6 includes a knife shaft 61 driven by a motor and at least one group of slitting heads 62 installed on the knife shaft 61.

[0052] Specifically, refer to the attached Figure 7 and 8 The slitting assembly 6 is integrally installed inside the frame 1, and its position is coordinated with the belt conveyor mechanism 3 to ensure that the slitting operation can be accurately performed during the cardboard conveying process. The slitting assembly 6 is mainly composed of a motor, a knife shaft 61, and a slitting knife head 62.

[0053] The motor is used as the power source of the slitting assembly 6. An efficient and stable type is selected. Its installation position is reasonably arranged in the frame 1 and is firmly connected to the frame 1 through the mounting bracket to ensure stability and reliability during operation. The output shaft of the motor is connected to the knife shaft 61 by a belt, and the belt can smoothly and accurately transmit the rotational power of the motor to the knife shaft 61.

[0054] The blade shaft 61 is generally made of high-strength alloy steel, has good torsional resistance, and can maintain stable operation under high-speed rotation.

[0055] In terms of specific structure, both ends of the cutter shaft 61 are installed on the frame 1 through high-precision bearing seats. The selection and installation position of the bearing seats are precisely calculated to ensure that the cutter shaft 61 has sufficient support and positioning accuracy during rotation, reducing radial and axial runout, thereby ensuring the stability and processing accuracy of the slitting head 62 during operation.

[0056] The slitting heads 62 are installed on the blade shaft 61, at least in one group, and the number and layout can be adjusted according to actual processing requirements. The slitting heads 62 are generally made of hard alloy material, which has extremely high hardness and wear resistance, and can adapt to high-intensity slitting processing tasks. The cutting edges are finely ground, sharp and flat, ensuring that the edges cut on the cardboard are smooth and neat without burrs and tears.

[0057] The slitting cutter head 62 is connected to the cutter shaft 61 via a high-precision cutter disc.

[0058] In most cases, for the convenience of maintenance, the connection between the cutter disc and the cutter shaft 61 is a key connection.

[0059] During the cardboard processing, when the cardboard is transported to the working area of ​​the slitting assembly 6 through the belt conveyor mechanism 3, the slitting assembly 6 starts to work. After the motor is started, the knife shaft 61 is driven to rotate through the coupling, and then the slitting head 62 installed on the knife shaft 61 rotates at a high speed. During the rotation process, the slitting head 62 contacts the surface of the cardboard and applies appropriate pressure, and performs precise slitting processing on the cardboard according to the preset slitting depth and path.

[0060] The working parameters of the slitting assembly 6, such as the rotation speed of the motor, the rotation speed of the slitting head 62, and the slitting pressure, can be precisely controlled and adjusted by the controller. The controller automatically adjusts the working state of the slitting assembly 6 according to the preset processing parameters and the material, thickness and other characteristics of the cardboard to achieve the best slitting effect. For example, for thicker or harder cardboard, the controller can appropriately increase the speed of the motor and the pressure of the slitting head 62 to ensure the depth and quality of slitting; while for thinner or softer cardboard, the speed and pressure can be reduced accordingly to avoid excessive cutting or damage to the cardboard.
