Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard production technology, and more specifically, to a fully automatic alignment device for corrugated cardboard production. Background Technology

[0002] Corrugated cardboard, also known as corrugated paperboard, is made by bonding at least one layer of corrugated paper and one layer of linerboard (also called boxboard). It has good elasticity and extensibility. It is mainly used to manufacture cartons, carton fillings, and other packaging materials for fragile goods. It is made by pulping straw pulp and waste paper to create a base paperboard similar to cardboard, which is then mechanically rolled into a corrugated shape. Finally, it is bonded to linerboard using adhesives such as sodium silicate.

[0003] In the corrugated cardboard production industry, cardboard is prone to shifting during transportation. In traditional production processes, the cardboard is mostly adjusted manually and frequently. This method not only consumes a lot of manpower, but also causes workers to become fatigued from long hours of operation, resulting in untimely or inaccurate correction, which in turn leads to production interruptions and a decline in product quality. Some of the simple correction equipment used has poor versatility and adaptability, making it difficult to meet the production needs of corrugated cardboard of different specifications and materials. Moreover, the equipment has an unreasonable structural design, and its internal components are easily damaged by external environmental factors. It lacks effective protection measures, and its shock absorption performance is poor. Vibration during equipment operation will aggravate component wear, shorten the service life of the equipment, increase maintenance costs, and seriously restrict the efficiency and quality stability of corrugated cardboard production.

[0004] This invention can further improve the efficiency and quality stability of corrugated cardboard production. Utility Model Content

[0005] The present invention aims to solve the technical problems mentioned in the background art and provide a fully automatic correction device for corrugated cardboard production.

[0007] A further preferred embodiment: the limiting assembly includes a limiting plate, a cylinder, and a limiting block. The limiting plate is mounted on the upper end of the bracket, and the output end of the cylinder is connected to the limiting block by bolts. The limiting block and the cylinder are detachably connected.

[0008] A further preferred embodiment: the positioning assembly includes a positioning block, a connecting block, a rotating rod, and a motor. The bottom of the positioning block contacts the upper end of the bracket, and the connecting block is fixedly installed on the outside of the positioning block.

[0009] A further preferred embodiment: the rotating rod passes through both ends of the connecting block, the connecting block and the rotating rod are connected by a thread, and the bottom of the rotating rod is connected to an output end of the motor. The two ends of the conveying roller can be embedded inside the positioning block, and are movably connected to the positioning block.

[0010] A further preferred embodiment: a second motor is installed on the outside of the telescopic cover, a screw is fixedly installed at the output end of the second motor, and two sliders are nested on the outer surface of the screw, with the two sliders being movably connected to the screw.

[0011] A further preferred embodiment: positioning rods are fixedly installed on the upper ends of the two sliders, and a sliding groove is opened at the upper end of the inside of the telescopic cover. The positioning rods can be embedded in the sliding grooves, and the positioning rods and the sliding grooves are slidably connected.

[0012] A further preferred embodiment: the two ends of the correction roller are respectively installed inside the two sliders, and the correction roller is detachably connected to the two sliders.

[0013] A further preferred embodiment: the bottom of the telescopic cover is equipped with several automatically telescopic legs.

[0014] A further preferred embodiment: a control unit is installed on the outside of the telescopic cover, and the control unit is electrically connected to each component.

[0015] A further preferred embodiment: the bottom of the bracket is provided with a support leg, and the bottom of the support leg is made of rubber.

[0016] Beneficial effects:

[0017] 1. By setting up a positioning group, which mainly consists of a positioning block, a connecting block, a rotating rod, and a motor, the height of the transport roller can be precisely adjusted. When the motor starts, it drives the rotating rod to rotate. Because the rotating rod is threadedly connected to the connecting block, the connecting block and the positioning block move up and down, thereby adjusting the height of the transport roller. This function allows the device to adapt to the transport needs of corrugated cardboard of different thicknesses and specifications, greatly improving the versatility and applicability of the device. Moreover, the positioning blocks are embedded at both ends of the transport roller and are movably connected to ensure its normal rotation to assist in transporting the cardboard. When cardboard deviation is detected, the positioning group can transmit the signal to the control machine in time, providing the prerequisite for subsequent correction operations, ensuring the smooth operation of the entire production process, effectively avoiding production problems caused by mismatched transport roller height or failure to detect cardboard deviation in time, and ensuring production efficiency and product quality.

[0018] 2. By setting up a limit group, which includes a limit plate, a cylinder, and a limit block, the limit plate is fixed to the upper end of the bracket, providing basic support for the entire limit system. During the transportation of corrugated cardboard, if the cardboard shifts to one side and approaches the limit position, the controller quickly instructs the cylinder to start. The cylinder output pushes the limit block to move towards the cardboard, preventing the cardboard from shifting further. This precisely limits the movement of the cardboard within a certain range, effectively preventing the cardboard from exceeding the specified range during transportation. At the same time, the limit block and the cylinder are detachably connected. When the limit block is worn or when different specifications of limit blocks need to be replaced for different production needs, disassembly and installation are very convenient. This not only reduces equipment maintenance costs but also allows for flexible adjustment of the limit position according to actual production conditions, providing more precise limit control for the corrugated cardboard, reducing production interruptions and product quality degradation caused by excessive cardboard shift, and improving the stability and continuity of production.

[0019] 3. Equipped with a correction roller installed inside a telescopic cover, driven by a motor, screw, and slider, the system activates the motor upon receiving a cardboard offset signal. The screw rotates, causing the slider to move axially. The upper positioning rod of the slider slides and guides the correction roller in the groove, changing its position and applying a lateral force to the offset cardboard, thus returning it to the correct transport path. Its simple structure, rapid and accurate operation, and quick response to cardboard offset significantly improve correction efficiency, ensuring the continuity and stability of corrugated cardboard production. Furthermore, the correction roller and slider are detachably connected, facilitating quick disassembly and replacement when the correction roller wears or malfunctions during operation, reducing maintenance time, improving maintainability, and ensuring efficient production.

[0020] 4. In summary, this fully automatic alignment device for corrugated cardboard production, through the setting of limit groups and other structures, allows the positioning group, limit group, and alignment roller to work together in corrugated cardboard production, each demonstrating its advantages. The positioning group, by adjusting the height of the transport rollers, adapts to different specifications of cardboard and can also provide timely feedback on offset signals; the limit group, driven by cylinders, precisely limits the movement range of the cardboard, and its detachable design facilitates maintenance and flexible adjustment; the alignment roller, driven by a motor and screw, can quickly respond to offsets, has a simple structure, and is detachable, facilitating maintenance and replacement. The coordinated work of these three components not only improves the versatility and applicability of the device, but also ensures the stability and continuity of production, reduces maintenance costs, and effectively improves the production efficiency and product quality of corrugated cardboard.

[0026] The following will refer to the appendix in the embodiments of this utility model. Figures 1-4 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0027] Please see Figure 1-4 In this embodiment of the present invention, a fully automatic correction device for corrugated cardboard production includes: a support 1, a conveyor 2 disposed inside the support 1, limit groups 3 fixedly installed on both sides of the upper end of the support 1, a conveyor roller 4 disposed above the conveyor 2, positioning groups 5 disposed at both ends of the conveyor roller 4, a telescopic cover 6 nested on the outside of the support 1, a correction roller 7 disposed inside the telescopic cover 6, and sensors disposed on the sides of the positioning groups 5; several automatic telescopic legs disposed at the bottom of the telescopic cover 6; a control unit disposed on the outside of the telescopic cover 6, the control unit being electrically connected to each component; and support legs disposed at the bottom of the support 1, the bottom of the support legs being made of rubber.

[0028] Corrugated cardboard is transported on conveyor 2. Limiting groups 3, located on both sides of the upper end of support 1, restrict the cardboard's lateral position during transport, preventing excessive deviation. Transport rollers 4 assist in transport and provide initial positioning. When the cardboard deviates during transport, sensors detect the change in position and transmit a signal to the control unit. Upon receiving the signal, the control unit controls the correction rollers 7 within the telescopic cover 6 to apply a lateral force to the deviated cardboard, returning it to the correct transport path, thus achieving automatic correction. The control unit is electrically connected to all components, coordinating the operation of conveyor 2, transport rollers 4, automatic telescopic legs, and correction rollers 7, ensuring the automation and accuracy of the entire correction process. The support legs at the bottom of support 1 stabilize the entire device; their rubber bottom increases friction with the ground, preventing shaking or displacement during operation. The fully automatic correction function can detect and correct cardboard deviation in real time, reducing... The reduced need for manual intervention avoids production interruptions and readjustments caused by cardboard misalignment, thereby improving the production efficiency of corrugated cardboard. Precise alignment control ensures that the corrugated cardboard maintains the correct position and posture during transportation, reducing quality problems such as wrinkles and damage caused by misalignment, and improving product quality stability. The elimination of frequent manual adjustments to the cardboard position reduces worker workload, improves the working environment, and also reduces instances of untimely or inaccurate alignment due to human fatigue. The device achieves flexible control of each component through a control unit, adapting to the production needs of corrugated cardboard of different specifications and materials, exhibiting strong versatility and adaptability. The telescopic cover 6 protects the internal alignment rollers 7 and automatic telescopic legs from external environmental influences such as dust and moisture, extending the equipment's service life. Simultaneously, the rubber support legs also provide some shock absorption, reducing wear and tear on components during equipment operation.

[0029] In this embodiment of the utility model, the limiting group 3 includes a limiting plate 301, a cylinder 302, and a limiting block 303. The limiting plate 301 is installed on the upper end of the bracket 1. The output end of the cylinder 302 is connected to the limiting block 303 by bolts. The limiting block 303 and the cylinder 302 are detachably connected. The positioning group 5 includes a positioning block 501, a connecting block 502, a rotating rod 503, and a motor 504. The bottom of the positioning block 501 contacts the upper end of the bracket 1. The connecting block 502 is fixedly installed on the outside of the positioning block 501. The rotating rod 503 passes through the upper and lower ends of the connecting block 502. The connecting block 502 and the rotating rod 503 are threadedly connected, and the bottom of the rotating rod 503 is connected to the output end of the motor 504. The conveying roller... 4. Both ends can be embedded inside the positioning block 501, and are movably connected to the positioning block 501; a second motor 601 is installed on the outside of the telescopic cover 6, and a screw 602 is fixedly installed at the output end of the second motor 601. Two sliders 603 are nested on the outer surface of the screw 602, and are movably connected to the screw 602; a positioning rod 604 is fixedly installed on the upper end of the two sliders 603, and a sliding groove 605 is opened at the upper end of the telescopic cover 6, and the positioning rod 604 can be embedded inside the sliding groove 605, and is slidably connected to the sliding groove 605; the two ends of the correction roller 7 are respectively installed inside the two sliders 603, and are detachably connected to the two sliders 603.

[0030] The limiting plate 301 is installed on the upper end of the bracket 1 as a fixing component. When the corrugated cardboard is transported on the conveyor 2, if the cardboard shifts to one side and approaches the limiting position, the controller issues a command, and the cylinder 302 starts. The output end of the cylinder 302 pushes the limiting block 303, which is bolted to it, to move towards the cardboard. The limiting block 303 can prevent the cardboard from shifting further, thus limiting the movement of the cardboard within a certain range. Since the limiting block 303 and the cylinder 302 are detachably connected, it is easy to disassemble and install when the limiting block 303 is worn or needs to be replaced with a different specification of limiting block 303. The bottom of the positioning block 501 contacts the upper end of the bracket 1, providing stable support. The connecting block 502 is fixed to the outside of the positioning block 501. The rotating rod 50... 3. A through-connector 502 is threadedly connected to the connecting block 502. The bottom of the rotating rod 503 is connected to the output end of motor 1 504. When the height of the transport roller 4 needs to be adjusted, motor 1 504 starts, driving the rotating rod 503 to rotate. Since the rotating rod 503 is threadedly connected to the connecting block 502, the rotation of the rotating rod 503 will cause it to move in the vertical direction, thereby driving the connecting block 502 and the positioning block 501 to move up and down, thus adjusting the height of the transport roller 4. The two ends of the transport roller 4 are embedded in the positioning block 501 and are movably connected to ensure that the transport roller 4 can rotate normally to assist in transporting corrugated cardboard. When the positioning group 5 detects that the corrugated cardboard has shifted, it transmits a signal to the control machine. The control machine controls motor 2 601 to start, and the screw at the output end of motor 2 601... When rod 602 rotates, the two sliders 603 are movably connected to screw 602. The rotation of screw 602 causes the two sliders 603 to move axially along screw 602 (the sliders 603 move in the corresponding direction according to the cardboard offset direction). The positioning rod 604 at the upper end of slider 603 slides in the groove 605 inside the telescopic cover 6, guiding and stabilizing the movement of slider 603. As slider 603 moves, the position of the correction roller 7 installed inside slider 603 also changes accordingly, applying a lateral force to the offset cardboard, returning the cardboard to the correct transport path. Since the correction roller 7 is detachably connected to slider 603, it is convenient to maintain and replace the correction roller 7. The cylinder 302 and limit block 303 in the limit group 3 cooperate to... The positioning unit 5, through the design of motor 504, rotating rod 503, and connecting block 502, allows for convenient and precise adjustment of the height of the transport roller 4. This enables the device to adapt to the transportation needs of corrugated cardboard of different thicknesses or specifications, improving its versatility and applicability. The driving mechanism of the correction roller 7, achieved through motor 601, screw 602, and slider 603, is simple in structure and operates quickly and accurately. It can rapidly respond to cardboard deviation and perform correction operations, greatly improving correction efficiency and ensuring the continuity and stability of corrugated cardboard production.The detachable connection design between the limit block 303 and the cylinder 302, and between the correction roller 7 and the slider 603, allows for quick and convenient disassembly and replacement of relevant components during operation when wear or failure occurs. This reduces maintenance time and costs, and improves maintainability. The sliding connection design between the positioning rod 604 and the slide 605 provides stable guidance for the movement of the slider 603, ensuring the stability of the correction roller 7 during movement, thereby improving the reliability and correction accuracy of the entire correction device.

[0031] Working Principle: When the fully automatic alignment device for corrugated cardboard production is working, the corrugated cardboard is placed on the conveyor 2 and transported by the conveyor rollers 4. The limit groups 3 on both sides of the upper end of the support 1 limit the left and right position of the cardboard through the limit plate 301, cylinder 302 and limit block 303. When the cardboard deviates close to the limit, the controller commands the cylinder 302 to push the limit block 303 to stop the cardboard from deviating further. During transportation, if the cardboard deviates, the sensor on the side of the positioning group 5 will detect the position change and transmit the signal to the controller. After receiving the signal, the controller starts the motor 601, and the screw 602 at its output end rotates, driving the two sliders 603 movably connected to the screw 602 to move axially. The positioning rod 604 at the upper end of the slider 603 slides and guides in the slide groove 605 inside the telescopic cover 6. As the slider 603 moves, the position of the correction roller 7 installed inside the slider 603 changes, applying a lateral force to the offset cardboard and returning it to the correct transport path. In addition, the motor 504, rotating rod 503, and connecting block 502 in the positioning group 5 can adjust the height of the transport roller 4 to accommodate different cardboard specifications. The detachable design of the limit block 303 and cylinder 302, and the correction roller 7 and slider 603 facilitates component maintenance and replacement. The sliding connection between the positioning rod 604 and the chute 605 ensures the stability of the movement of the correction roller 7. The controller is electrically connected to each component, coordinating the operation of the transport machine 2, transport roller 4, automatic telescopic legs, and correction roller 7 to achieve automated and precise correction, thereby improving the production efficiency and product quality of corrugated cardboard, reducing the labor intensity of workers, and enhancing the versatility and adaptability of the device.
