Description

Technical Field

[0001] This utility model relates to the field of insulating paperboard manufacturing technology, and in particular to an ultra-high voltage insulating paperboard testing and conveying device. Background Technology

[0002] Ultra-high voltage (UHV) insulating paperboard is a key insulating material in power equipment. Its thickness, density, and insulation performance directly affect the safe and stable operation of the power system. Therefore, strict quality inspection and classification of each piece of paperboard during its production process is crucial. Existing production lines generally employ manual sampling, offline sorting, and manual stacking for the inspection, sorting, stacking, and transfer of insulating paperboard. This method involves high labor input, low overall efficiency, and is difficult to match the pace of modern high-speed production lines. Furthermore, the inspection accuracy and reliability are insufficient, potentially leading to missed inspections and misjudgments, making it difficult to achieve full inspection. Utility Model Content

[0003] Based on the above, the purpose of this utility model is to provide an ultra-high voltage insulating paperboard testing and conveying device to solve the problems of low testing reliability, low production efficiency, and high dependence on manual labor in the existing technology.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A testing and conveying device for ultra-high voltage insulating paperboard includes a conveyor table, a testing mechanism, a stacking platform, a lifting mechanism, a balancing mechanism, and a transfer platform vehicle, wherein:

[0006] The conveyor table docks with the unloading machine, used to receive and continuously convey the cardboard output from the unloading machine;

[0007] The testing unit is located on the conveyor path of the conveyor table and is used to test the performance indicators of the cardboard.

[0008] The stacking platform is connected to the conveyor platform, which is used to receive cardboard that has passed the inspection by the testing agency;

[0009] The lifting mechanism is used to drive the stacking platform to move up and down so that multiple cardboard boxes can be stacked in sequence.

[0010] The straightening mechanism is located on the outside of the stacking platform and is used to align the various cardboard pieces on the platform.

[0011] Transfer platform vehicles are used to move stacking platforms that hold a set number of cardboard pieces.

[0012] As an optional solution, the inspection mechanism includes a laser thickness gauge, a metal detector, an inkjet printer, and an alarm separation component. The laser thickness gauge is used for online, non-contact measurement of the thickness of the cardboard. The metal detector is used to detect and identify whether there are any metal foreign objects in the cardboard. The inkjet printer is used to print information markings on the cardboard that passes the inspection. The alarm separation component is used to sound an alarm when non-conforming cardboard is detected and to remove the non-conforming cardboard from the conveyor.

[0013] As an optional solution, the conveying end of the conveyor platform is equipped with a support frame, on which four columns are installed. The top of each column is equipped with a pulley. The lifting mechanism includes a first drive cylinder and four sliding blocks. The four sliding blocks are slidably mounted on the four columns. The output end of the first drive cylinder is connected to the four sliding blocks via a steel wire rope that passes over the corresponding pulley, thereby driving the four sliding blocks to lift synchronously. A first crossbeam is connected between the two sliding blocks closest to the conveyor platform, and a second crossbeam is connected between the two sliding blocks furthest from the conveyor platform. The first and second crossbeams cooperate to support the two opposite sides of the stacking platform.

[0014] As an alternative, the transfer platform vehicle is positioned between the first and second crossbeams. When the first and second crossbeams move from above the loading platform of the transfer platform vehicle to below the loading platform of the transfer platform vehicle, the stacking platform is transferred from the first and second crossbeams to the transfer platform vehicle.

[0015] As an alternative, the straightening mechanism includes a baffle, a pusher plate, and a suction cup assembly. The baffle is located at the end of the stacking platform away from the conveyor, and two pushers are distributed on both sides of the stacking platform. The two pushers are aligned to center the cardboard. The suction cup assembly is located above the baffle and is used to move one end of the cardboard output from the conveyor to the baffle.

[0016] As an optional solution, the suction cup assembly includes a second drive cylinder, a third drive cylinder, and a vacuum suction cup. The second drive cylinder is mounted on a support frame and its output direction is the same as or opposite to the conveying direction of the conveyor table. The third drive cylinder is mounted on the output end of the second drive cylinder, and its output direction is perpendicular to the conveying plane of the conveyor table. The vacuum suction cup is mounted on the output end of the third drive cylinder and is used to adsorb or release cardboard.

[0017] As an alternative, the support frame is equipped with sensors for detecting the stacking height of the cardboard.

[0018] As an alternative, a number of spaced conveyor rollers are arranged on the conveyor table along the conveying direction. The conveyor rollers include a drive roller and a driven roller with a gap located above the drive roller. The drive roller is driven to rotate by a motor, and the driven roller is driven by a cylinder to move closer to or away from the drive roller. Guide bars are arranged between adjacent conveyor rollers.

[0019] The beneficial effects of this utility model are:

[0020] This ultra-high voltage insulating paperboard testing and conveying device integrates conveying, online testing, automatic sorting, and stacking functions to form a continuous automated production line. It significantly improves the testing and conveying efficiency of paperboard, reduces labor costs and labor intensity, and meets the stringent quality consistency requirements of ultra-high voltage insulating paperboard. In particular, the lifting design of the stacking platform, in conjunction with the sorting mechanism, ensures that the paperboard is stacked neatly and stably, facilitating subsequent transfer and improving overall operational efficiency and reliability.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0038] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0039] Furthermore, the terms "first" and "second" are merely used to distinguish between different terms in description and do not have any special meaning.

[0040] Please see Figures 1 to 5As shown, this embodiment provides an ultra-high voltage insulating paperboard testing and conveying device, including a conveying platform 1, a testing mechanism 2, a stacking platform 3, a lifting mechanism 4, a aligning mechanism 5, and a transfer platform 6. The conveying platform 1 connects to a plate unloading machine 7 and is used to receive and continuously convey the paperboard 8 output by the plate unloading machine 7. The testing mechanism 2 is located on the conveying path of the conveying platform 1 and is used to test the performance indicators of the paperboard 8. The stacking platform 3 connects to the conveying platform 1 and is used to receive the paperboard 8 that has passed the testing by the testing mechanism 2. The lifting mechanism 4 drives the stacking platform 3 to move up and down, so as to stack multiple paperboards 8 sequentially. The aligning mechanism 5 is located on the outside of the stacking platform 3 and is used to align the various paperboards 8 on the stacking platform 3. The transfer platform 6 is used to remove the stacking platform 3 containing a set number of paperboards 8.

[0041] Thus, by integrating conveying, online detection, automatic sorting and stacking functions, a continuous automated production line is formed, which significantly improves the detection and conveying efficiency of paperboard 8, reduces labor costs and labor intensity, and meets the stringent quality consistency requirements of ultra-high voltage insulating paperboard 8; among them, the lifting design of the stacking platform 3 and the sorting mechanism 5 work together to ensure that the paperboard 8 is stacked neatly and stably, which facilitates subsequent transfer and improves the overall operation efficiency and reliability.

[0042] In some embodiments, the detection mechanism 2 includes a laser thickness gauge, a metal detector, an inkjet printer, and an alarm separation component. The laser thickness gauge is used to measure the thickness of the cardboard 8 online and non-contactly. The metal detector is used to detect and identify whether there are any metal foreign objects in the cardboard 8. The inkjet printer is used to print information markings on the qualified cardboard 8. The alarm separation component is used to sound an alarm when an unqualified cardboard 8 is detected and to remove the unqualified cardboard 8 from the conveyor table 1.

[0043] Among them, the laser thickness gauge uses the triangulation principle for non-contact measurement, avoiding scratches or deformation problems that may be caused by contact measurement. It has high detection accuracy, no radiation, good safety performance, and can monitor online in real time. The metal detector can quickly detect and identify whether there are metal foreign objects such as iron, stainless steel, copper, and aluminum mixed in the cardboard 8, preventing metal impurities from damaging subsequent processing equipment and causing the cardboard 8 to fail to meet insulation performance standards. The inkjet printer prints information labels (such as production date, batch, barcode, QR code, etc.) on the qualified cardboard 8, realizing traceability function, which is convenient for warehousing, logistics management and consumer inquiry. The alarm separation component can promptly alarm (such as sound and light alarm) when non-conforming products are detected, and quickly link with the rejection device to remove non-conforming products from the conveyor table 1, preventing non-conforming products from flowing into subsequent links and reducing the workload and error rate of manual sorting. Thus, the detection mechanism 2 realizes online, non-contact dual-indicator detection of thickness and foreign objects. Qualified products are marked with inkjet printing, and non-conforming products are automatically alarmed and rejected, achieving zero missed detection and data traceability.

[0044] In some embodiments, a support frame 41 is provided at the conveying end of the conveying platform 1. Four columns are mounted on the support frame 41, and pulleys 42 are mounted on the top of each column. The lifting mechanism 4 includes a first drive cylinder 43 and four sliding blocks 44. The four sliding blocks 44 are slidably mounted on the four columns. The output end of the first drive cylinder 43 is connected to the four sliding blocks 44 via steel wire ropes 45 that pass over the corresponding pulleys 42, thereby driving the four sliding blocks 44 to lift synchronously. A first crossbeam 46 connects the two sliding blocks 44 closest to the conveying platform 1, and a second crossbeam 47 connects the two sliding blocks 44 furthest from the conveying platform 1. The first crossbeam 46 and the second crossbeam 47 cooperate to support the two opposite sides of the stacking platform 3. See details... Figure 3 and Figure 4 .

[0045] Furthermore, the parking position of the transfer platform vehicle 6 is between the first crossbeam 46 and the second crossbeam 47. When the first crossbeam 46 and the second crossbeam 47 move from above the loading platform of the transfer platform vehicle 6 to below the loading platform of the transfer platform vehicle 6, the stacking platform 3 is transferred from the first crossbeam 46 and the second crossbeam 47 to the transfer platform vehicle 6.

[0046] The four sliding blocks 44 are driven to rise and fall synchronously by the first drive cylinder 43, wire rope 45 and pulley 42, which ensures the smooth lifting and lowering of the stacking platform 3 and prevents the cardboard 8 from falling and being damaged due to tilting or shaking during the lifting process. The first crossbeam 46 and the second crossbeam 47 are cleverly used to support the stacking platform 3, realizing the automated transfer of the stacking platform 3 from the lifting mechanism 4 to the transfer platform 6 without any forklift action, which helps to improve the unloading efficiency, reduce the time and physical labor of manual handling, better protect the cardboard 8 and reduce collisions and squeezing during transportation. In addition, when one transfer platform 6 carries the stacking platform 3 with cardboard 8 and moves it away, another transfer platform can simultaneously carry the empty stacking platform 3 and stack cardboard 8, so that the production line can continue to operate without stopping.

[0047] In some embodiments, the straightening mechanism 5 includes a baffle 51, a pusher plate 52, and a suction cup assembly. The baffle 51 is disposed at one end of the stacking platform 3 away from the conveyor platform 1. The two pusher plates 52 are distributed on both sides of the stacking platform 3. The two pusher plates 52 are aligned to center the cardboard 8. The suction cup assembly is disposed above the baffle 51. The suction cup assembly is used to move one end of the cardboard 8 output from the conveyor platform 1 against the baffle 51.

[0048] The baffle 51 provides a reliable positioning reference surface for the stacking of cardboard 8, ensuring that one end of the cardboard 8 is neat after being moved from the conveyor 1 to the stacking platform 3. The suction cup assembly can efficiently and accurately move the cardboard 8 against the baffle 51, improving the leveling efficiency. The pusher plate 52 can effectively correct the positional deviation of the cardboard 8 by pushing it from both sides, making the cardboard 8 centered and aligned on the stacking platform 3, forming a neat stack, improving the stability of the stack, and facilitating subsequent stacking, transportation, and storage. In the process, it is best to first gradually pull the cardboard 8 against the baffle 51 for positioning by the suction cups, and then center it with the pusher plates 52 on both sides, controlling the edge error of each stack of cardboard 8 and completely solving the problem of uneven stacking by manual stacking.

[0049] Furthermore, the suction cup assembly includes a second drive cylinder 53, a third drive cylinder 54, and a vacuum suction cup 55. The second drive cylinder 53 is mounted on the support frame 41, and the output direction of the second drive cylinder 53 is the same as or opposite to the conveying direction of the conveyor table 1. The third drive cylinder 54 is mounted on the output end of the second drive cylinder 53, and the output direction of the second drive cylinder 53 is perpendicular to the conveying plane of the conveyor table 1. The vacuum suction cup 55 is mounted on the output end of the third drive cylinder 54, and the vacuum suction cup 55 is used to adsorb or release the cardboard 8.

[0050] The second drive cylinder 53 and the third drive cylinder 54 work in series to help the cardboard 8 get off the conveyor table 1 and to make the cardboard 8 abut against the baffle 51 for positioning. The vacuum suction cup 55 can gently pick up the cardboard 8 to avoid damage to the surface of the cardboard 8 (such as scratches or indentations). It works with the second drive cylinder 53 and the third drive cylinder 54 to complete the picking and releasing actions, with a high degree of automation.

[0051] In some embodiments, the support frame 41 is provided with a sensor for detecting the stacking height of the cardboard 8.

[0052] The sensor and the lifting mechanism 4 work together to ensure that the top layer of cardboard 8 is always at the same receiving height, avoiding impact or jamming. At the same time, it can accurately count and realize the stacking of a set number of cardboard 8 on the stacking platform 3. When the sensor detects that the stacking height has reached a certain value, it drives the lifting mechanism 4 to lower the stacking platform 3 until the stacking platform 3 is handed over to the transfer platform 6 for support, realizing automatic stacking.

[0053] In some embodiments, a plurality of spaced conveying rollers are arranged on the conveying table 1 along the conveying direction. Each conveying roller includes a driving roller 11 and a driven roller 12 positioned above the driving roller 11. The driving roller 11 is driven to rotate by a motor, and the driven roller 12 is driven by a cylinder 13 to move closer to or away from the driving roller 11. See details... Figure 5 Guide bars 14 are provided between adjacent conveyor rollers.

[0054] The driving roller 11 provides the conveying power, and the driven roller 12 can move closer to or further away from the driving roller 11. This can adjust the clamping force on the paperboard 8 and adapt to paperboards 8 with different thicknesses, materials and surface characteristics, avoiding slippage or damage to the paperboard 8 and meeting the conveying requirements. The guide bar 14 helps guide the paperboard 8 to move smoothly along the predetermined conveying direction, which is convenient for subsequent accurate detection and output.

[0055] Production process: The UHV insulating paperboard testing and conveying device is set after the unloading machine 7, and connects to the paperboard 8 output by the unloading machine 7 to identify indicators such as thickness, density and insulation, separate / classify, convey, test, and align, and finally transfer to the semi-finished product warehouse through the transfer platform vehicle 6. The whole process is completed automatically and intelligently according to the transmission rhythm.

[0056] In summary, this UHV insulating paperboard inspection and conveying device, through automated conveying, online inspection (thickness and metal foreign objects), intelligent straightening and stacking functions, forms a continuous production line, significantly improving inspection efficiency and quality consistency. Its unique features include: laser thickness gauges and metal detectors enabling non-contact, high-precision inspection to avoid damage; inkjet printers establishing a product traceability system; straightening mechanism 5 ensuring neat and stable stacking; and lifting mechanism 4 and transfer platform 6 working together to automatically transfer the stacking platform 3. The entire process reduces manual intervention, ensuring the production quality of the paperboard 8 and meeting the stringent requirements of UHV insulating paperboard 8 for insulation, mechanical strength, and heat resistance.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
