Description

Technical Field

[0001] This invention relates to the field of transformer insulating paper production technology, specifically to a method for using an insulating paper shearing machine for transformer production. Background Technology

[0002] Transformer insulating paper is an indispensable key insulating material in the transformer manufacturing process. Its main function is to form reliable electrical isolation between various components of the transformer, prevent short circuit faults, and ensure the safe and stable operation of the transformer.

[0003] Chinese patent CN202320977029.X discloses a transformer insulation paper shearing machine, including a processing table. A support frame is fixedly connected to the upper end of the processing table. A hydraulic rod with one end penetrating the support frame is fixedly installed at the upper end of the support frame. A cleaning box is fixedly connected to the outer side of the support frame, and a support plate is fixedly connected to the inner wall of the support frame. This transformer insulation paper shearing machine, through the cooperation of the extrusion block and the cleaning box, cuts the insulation paper conveyed to the inner side of the support frame. The activated hydraulic rod moves the cutter downwards, and simultaneously, through the connecting frame and the top horizontal plate, moves the top extrusion block downwards, thus simultaneously extruding and fixing the insulation paper located inside the support frame while shearing, improving the stability of the insulation paper during shearing. Meanwhile, the brushes located inside the cleaning box clean the insulation paper conveyed to the inner side of the support frame, improving the flatness and cleanliness of the insulation paper during the shearing process.

[0004] Chinese patent CN202221297777.5 discloses an insulating paper shearing machine for transformer production, including a workbench and a shearing mechanism on the workbench. The shearing mechanism includes a shearing blade. A positioning mechanism is provided on the side of the workbench corresponding to the shearing mechanism. The positioning mechanism includes a positioning frame on the side of the workbench, a threaded rod on the positioning frame, a crank handle at the end of the threaded rod, a positioning plate on the threaded rod, and a threaded hole on the positioning plate. The threaded rod passes through the threaded hole and connects to the positioning plate. Two guide rods are also provided on the positioning frame, and guide holes are provided on the positioning plate corresponding to the guide rods. The position of the positioning plate can be adjusted to clamp the insulating paperboard on a sliding plate. The sliding plate is then moved so that one end of the insulating paperboard contacts the positioning plate. The shearing blade on the shearing mechanism is then controlled to cut the insulating paperboard, ensuring that the cut insulating paperboard is of uniform length.

[0005] Chinese patent CN202420085523.X discloses a transformer insulation paper shearing machine, including an operating table. A feeding component is located on the top of the operating table, comprising a servo motor horizontally mounted on the right side wall of the operating table. T-shaped grooves are symmetrically formed on the front and back of the top of the operating table. Threaded rods are rotatably connected inside each of the two T-shaped grooves, and T-shaped sliding rods are threaded onto the circumference of each of the two threaded rods. The right ends of both threaded rods extend to the outside of the operating table, and rotating wheels are fixedly connected to the outer walls of the right ends of both threaded rods. Belts are installed on the outer walls of the two rotating wheels. The output end of the servo motor is fixedly connected to the right ends of the threaded rods. This machine can automatically feed insulation paper of different sizes, preventing finger cuts and improving safety, while also reducing manual labor and increasing shearing efficiency.

[0006] The aforementioned patent represents the closest prior art to this invention. While the technology disclosed in the patent has made some progress in the automated production of insulating paper shearing machines, enabling basic functions such as feeding, positioning, and cutting, and even some optimizations in cleaning or clamping, there is still room for improvement in the transfer and stacking of the cut insulating paperboard. For example, in the prior art, the cut insulating paperboard often requires manual transfer and stacking, which not only increases the labor intensity of operators and reduces overall production efficiency, but also easily leads to creases, contamination, or even damage to the insulating paperboard due to improper operation, affecting product quality.

[0007] Therefore, how to design an automatic transfer and stacking system that can efficiently, stably, and accurately complete the cutting of insulating paperboard, thereby further improving the automation level and production efficiency of transformer insulating paper production lines, is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0008] The purpose of this invention is to provide a method for using an insulating paper shearing machine for transformer production, in order to solve the problems mentioned in the background art, which require manual transfer and stacking of cardboard, increasing the labor intensity of operators, reducing overall production efficiency, and easily causing creases, contamination, or even damage to the insulating cardboard due to improper operation, thus affecting product quality.

[0009] To achieve the above objectives, the present invention provides the following technical solution: an insulating paper shearing machine includes a cutting table, a conveyor is provided at the feeding end of the cutting table, a cutting mechanism is provided above the cutting table and on the side close to the conveyor, a support plate X-axis sliding seat is slidably provided at the bottom of the cutting table along the longitudinal direction, a support plate Z-axis sliding seat is slidably provided on the support plate X-axis sliding seat along the vertical direction, a plurality of support plates arranged in the transverse direction are fixed on the support plate Z-axis sliding seat, and a clearance groove is provided through the cutting table, corresponding one-to-one with the support plates and extending along the longitudinal direction; Multiple trays are transitionally connected to the tray Z-axis sliding seat via a tray fixing platform; each tray includes a lifting part for directly supporting insulating paperboard, a connecting part connecting the lifting part and the tray fixing platform, and a limiting part provided at the end of the lifting part away from the cutter. A material transfer mechanism is provided at the end of the cutting table away from the conveyor. The material transfer mechanism includes a base mounting frame, a Y-axis material transfer slide that slides laterally on the top of the base mounting frame, a Z-axis material transfer slide that slides vertically on the top of the Y-axis material transfer slide, a transfer fork plate that is rotatably mounted on the Z-axis material transfer slide, the transfer fork plate including multiple fork heads that are arranged intersecting with the pallet, and a discharge push plate that can move along the extension direction of the fork heads on the top of the transfer fork plate; an object sensor is provided at the bottom of the transfer fork plate. A stacking platform is provided on one side of the material transfer mechanism. At least two stacking platforms are provided and slidably disposed on one side of the material transfer mechanism. The mechanism also includes a drive assembly for driving all the stacking platforms to move.

[0010] Instructions for using an insulating paper shearing machine for transformer production: S1. After the cutting mechanism finishes cutting a section of insulating cardboard, the Z-axis sliding seat and the tray move upward, and the corresponding lifting part inside the tray moves to the top surface of the cutting table. At the same time, the lifting part lifts up the cut insulating cardboard. S2. The tray X moves toward the sliding seat toward the position of the fork head. While the tray X moves toward the sliding seat, it also moves the tray and the insulating cardboard above the tray until the insulating cardboard is completely moved above the fork head. S3. When the Z-axis slide moves upward and the height of the fork head exceeds the height of the lifting part, the insulating cardboard on the lifting part is transferred to the fork head. The lifting part stops when it descends back to the height below the cutting table surface. The Z-axis slide stops when it moves to the maximum height. S4. The transfer fork plate and the insulating cardboard at the top of the fork head rotate until the fork head is aligned with the direction of the stacking platform. S5. The Y-axis transfer slide moves toward the stacking platform. The Y-axis transfer slide, along with the Z-axis transfer slide, the transfer fork plate, and the insulating cardboard at the top of the fork head, moves to the top of the stacking platform. S6. The transfer Z-axis slide moves downward, causing the transfer fork plate and the insulating cardboard located at the top of the fork head to gradually approach the already stacked insulating cardboard on the stacking platform. S7. The unloading pusher pushes the insulating cardboard off the fork head. At this time, the Y-direction slide moves away from the stacking platform. Simultaneously, the unloading pusher continues to push the insulating cardboard off the platform at the same speed as the Y-direction slide. Since the Y-direction slide moves in the opposite direction to the unloading pusher and the unloading pusher moves at the same speed, the unloading pusher stops relative to the stacking platform. The fork head gradually moves away from and separates from the stacking platform and the insulating cardboard.

[0011] Preferably, the cutting mechanism includes a gantry frame, the crossbeam of the gantry frame is located directly above the cutting table, and a cutter and a drive assembly for driving the cutter to move up and down are provided on the crossbeam of the gantry frame.

[0012] Preferably, the cutting table is provided with a cutting groove that is vertically corresponding to the cutting blade.

[0013] Preferably, the cutting mechanism further includes a clamping member, which includes an upper fixed plate and a lower clamping plate located below the upper fixed plate. The lower clamping plate slides vertically with the upper fixed plate. An elastic member is provided between the lower clamping plate and the upper fixed plate to prevent the lower clamping plate from moving upward. A drive assembly is provided on the gantry frame to drive the clamping member to move up and down.

[0014] Preferably, the top of the Y-axis material transfer slide is provided with an upwardly extending Z-axis extension plate seat, and the Z-axis material transfer slide is slidably disposed on the Z-axis extension plate seat in a vertical direction.

[0015] Preferably, the transfer fork plate is rotatably mounted on the Z-axis slide block of the transfer mechanism via a rotating shaft.

[0016] Preferably, multiple fork heads in the transfer fork plate are connected to a fork tail, the rotating shaft is fixed to the bottom of the fork tail, and a bearing seat that cooperates with the rotating shaft is provided on the top of the Z-axis slide block.

[0017] Preferably, the side of the stacking platform away from the transfer mechanism is provided with an upwardly extending protective plate.

[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention realizes the integrated automated cutting and stacking of insulating paperboard: the cutting mechanism precisely cuts the insulating paperboard to be cut, and the transfer mechanism smoothly transfers the cut insulating paperboard from the cutting table to the stacking table, where the stacking table achieves neat stacking of the insulating paperboard. The whole process does not require much manual intervention, greatly reducing manual operation links, reducing labor intensity, and significantly improving production efficiency.

[0019] 2. This invention improves the cutting and stacking quality of insulating paperboard: The clamping component in the cutting mechanism effectively ensures the positioning stability of the insulating paperboard during the cutting process, and, together with the precise cutting action of the cutter, ensures the accuracy of the cutting dimensions; When the transfer mechanism transfers the insulating paperboard, the coordinated action of the pallet and the transfer fork plate achieves a smooth transfer of the insulating paperboard, avoiding damage to the paperboard; During the stacking process, through the precise positioning of the infrared sensor, the reverse synchronous movement of the unloading push plate and the transfer Y-axis slide, the insulating paperboard is stacked very neatly, and the edge damage and burr generation that may be caused by directly pushing away the stacked paperboard are avoided, effectively protecting the edge quality of the insulating paperboard.

[0020] 3. This invention has continuous operation capability and improves equipment utilization: at least two stacking platforms are set and can slide. When a stacking platform is full of insulating cardboard, the corresponding drive component can drive the stacking platform to move, switching the empty stacking platform to the transfer position to continue receiving. The full stacking platform can be unloaded or processed on the side, avoiding equipment downtime caused by waiting for unloading, ensuring the continuity of production, and thus improving the overall utilization of the equipment.

[0021] 4. This invention features an ingenious structural design and stable, reliable operation: the connections and movements between components are precisely designed. For example, the X and Z-axis movement of the pallet, the rotation and X, Y, and Z-axis movement of the transfer fork, and the pushing action of the unloading pusher are all precisely controlled by drive components such as screw motors, cylinders, and drive motors, ensuring the stability and reliability of the entire equipment. The application of sensing elements such as object sensors and limit switches further improves the accuracy and automation level of the equipment's movements. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] For ease of description, the coordinate system is defined as follows: Figure 1 As shown, the X direction is vertical (front and back), the Y direction is horizontal (left and right), and the Z direction is vertical (up and down).

[0026] like Figures 1 to 7 As shown, a method for using an insulating paper shearing machine for transformer production is described. The insulating paper shearing machine includes a cutting table 1. The feeding end of the cutting table 1 is provided with a conveyor 10 for conveying insulating paperboard to be cut onto the cutting table 1. A cutting mechanism for cutting the insulating paperboard is provided above the cutting table 1 and on the side near the conveyor 10. A support plate X-axis sliding seat 13 is slidably provided on the bottom of the cutting table 1 along the longitudinal direction. A support plate Z-axis sliding seat 14 is slidably provided on the support plate X-axis sliding seat 13 along the vertical direction. A plurality of support plates 2 arranged in a transverse direction are fixed on the support plate Z-axis sliding seat 14. A clearance groove 12 is provided through the cutting table 1, corresponding one-to-one with the support plates 2 and extending longitudinally.

[0027] The cutting table 1 is provided with a material transfer mechanism at the end away from the conveyor 10. The material transfer mechanism includes a base mounting frame 41, a material transfer Y-axis slide 42 that slides laterally on the top of the base mounting frame 41, a material transfer Z-axis slide 43 that slides vertically on the top of the material transfer Y-axis slide 42, a transfer fork plate 5 that is rotatably mounted on the material transfer Z-axis slide 43, the transfer fork plate 5 including a plurality of fork heads 51 that are arranged intersectingly (staggered) with the pallet 2, and a discharge push plate 6 that can move along the extension direction of the fork heads 51 on the top of the transfer fork plate 5.

[0028] A stacking platform 8 is provided on one side of the material transfer mechanism.

[0029] It also includes drive components for moving the pallet X-axis sliding seat 13, pallet Z-axis sliding seat 14, material transfer Y-axis sliding seat 42, material transfer Z-axis sliding seat 43, transfer fork plate 5, and unloading push plate 6 respectively.

[0030] Specifically, in this embodiment, the conveyor 10 is any one of a belt conveyor, roller conveyor, or chain conveyor. The conveying surface of the conveyor 10 is flush with or slightly higher than the table surface of the cutting table 1 to ensure that the insulating paperboard can be smoothly transferred to the cutting table. The cutting table 1 is supported and fixed by a cutting table bracket 11, which is welded from common square tubing, resulting in a stable structure and light weight. The table surface of the cutting table 1 is made of steel plate with a thickness of not less than 10mm, and the surface is polished to reduce friction during the conveying of the insulating paperboard. The conveyor 10 is a conventional technology. Appropriate sizes and models can be selected based on the width and thickness of the insulating paperboard in actual production. Its specific structure and working principle will not be elaborated here.

[0031] Specifically, in this embodiment, the cutting mechanism includes a gantry frame 31, with its crossbeam located directly above the cutting table 1. A cutter 32 and a drive assembly (not shown in the figure) for driving the cutter 32 to move up and down are mounted on the crossbeam of the gantry frame 31. In the cutting field, common driving methods for moving the cutter and forming a cutting action include cylinder drive, hydraulic cylinder drive, and eccentric wheel drive. In this embodiment, a cylinder is used as an example for driving the cutter 32 to move up and down. The corresponding cylinder is fixed on the crossbeam of the gantry frame 31, and the cylinder's drive arm extends vertically. The cutter 32 is fixed to the top of the cylinder's drive arm. When the cylinder's drive arm extends downwards, it drives the cutter 32 to form a downward cutting action; when the cylinder's drive arm retracts upwards, it drives the cutter 32 to form a retracting action.

[0032] In this embodiment, the cutting table 1 is provided with a cutting groove 111 vertically corresponding to the cutter 32. When the cutter 32 cuts downwards, it enters the cutting groove 111 to avoid direct contact between the blade and the cutting table surface, thus preventing damage, and ensuring that the insulating cardboard can be completely cut. The width of the cutting groove 111 is slightly larger than the thickness of the cutter 32, and its depth is set according to the downward cutting stroke of the cutter 32, generally 5-15mm, which can be adjusted according to actual cutting needs. The blade of the cutter 32 can be made of high-carbon steel or high-speed steel, and the edge of the blade is hardened to improve wear resistance and sharpness. The shape of the blade can be designed as a straight line or a beveled line at a specific angle according to cutting needs.

[0033] To further improve the stability of the insulating cardboard during cutting, the cutting mechanism also includes a clamping element 33. For example... Figure 2 and Figure 10 As shown, the clamping member 33 includes an upper fixed plate 331 and a lower clamping plate 332 located below the upper fixed plate 331. The lower clamping plate 332 slides vertically with the upper fixed plate 331. An elastic member is provided between the lower clamping plate 332 and the upper fixed plate 331 to prevent the lower clamping plate 332 from moving upward. A drive assembly (not shown in the figure) is provided on the gantry frame 31 to drive the clamping member 33 to move vertically.

[0034] Specifically, the top of the lower clamping plate 332 is provided with a plurality of upwardly extending sliding connecting posts 333, and the upper fixing plate 331 is provided with insertion holes (not shown in the figure) corresponding to the sliding connecting posts 333. The insertion holes penetrate the upper fixing plate 331, and the sliding connecting posts 333 are slidably inserted into the corresponding insertion holes. The top of the sliding connecting posts 333 is provided with a limiting member to prevent the sliding connecting posts 333 from disengaging from the insertion holes. In one specific embodiment, the limiting member is a nut, and the top of the sliding connecting post 333 is provided with an external thread that mates with the nut. Under the obstruction of the nut, the sliding connecting post 333 is prevented from disengaging from the insertion hole, so that the lower clamping plate 332 can slide stably up and down along the insertion hole through the sliding connecting posts 333.

[0035] Preferably, the elastic element is a spring 334, which is sleeved on the outside of the corresponding sliding connecting post 333, and the spring 334 is located between the lower pressing plate 332 and the upper fixing plate 331.

[0036] Specifically, in this embodiment, the driving component used to drive the clamping member 33 to move up and down is either a cylinder or a hydraulic cylinder. Taking a cylinder as an example, the corresponding cylinder (not shown in the figure) is fixed on the crossbeam of the gantry 31. The driving arm of the cylinder extends vertically, and the top of the cylinder driving arm is fixed to the upper fixed plate 331. When the cylinder driving arm extends downward, it drives the upper fixed plate 331 and the lower clamping plate 332 connected to it to move downward as a whole. When the bottom of the lower clamping plate 332 contacts the surface of the insulating cardboard on the cutting table 1, the cylinder driving arm continues to extend downward. At this time, the sliding connecting column 333 slides upward relative to the upper fixed plate 331, the spring 334 is compressed and generates elastic force. This elastic force acts on the lower clamping plate 332, making it tightly press against the insulating cardboard. Thus, before or during the cutting action of the cutter 32, the periphery of the area to be cut of the insulating cardboard is effectively fixed, preventing the insulating cardboard from shifting or warping under the action of the cutting force, and ensuring the neatness of the cutting edge. After cutting, the cylinder drive arm retracts upward, causing the upper fixed plate 331 and the lower pressing plate 332 to move upward as a whole. The lower pressing plate 332 separates from the insulating cardboard, releasing the pressing state.

[0037] It is important to note that because the cutter used for cutting insulating cardboard has a certain thickness—the blade body thickness, excluding the cutting edge, is typically greater than 5mm—the cut portion of the cardboard will experience some displacement. Therefore, it is not suitable to use the clamping component 33 to clamp and fix the cut portion of the cardboard. This is because the cutter needs a certain amount of space to accommodate the cutting insulating cardboard after it makes a cut. If the insulating cardboard on both sides of the cutter is clamped and fixed, it will cause the cutter to experience significant lateral resistance during the cutting process. This may not only lead to cutter deformation or blade breakage, but also cause problems such as tearing and burrs on the cut edge because the cardboard cannot undergo slight natural displacement as the cutter enters the cutting process. Therefore, in this embodiment, the clamping member 33 is preferably positioned on the side of the cutter 32 facing the conveyor 10. The advantage of this design is that the cut of the insulating cardboard to be cut on the front side of the cutter 32 (with the side of the cutter 32 facing the conveyor 10 as the front side) remains flush under the clamping action of the clamping member 33, which does not affect the neatness of the insulating cardboard to be cut in the next cut. Although the cut insulating cardboard on the rear side of the cutter 32 is displaced, the displaced insulating cardboard provides space for the cutter 32 to accommodate it, preventing problems such as blade breakage, tearing of the cutting edge of the insulating cardboard, and burrs caused by fixing both sides.

[0038] Furthermore, a layer of rubber or silicone anti-slip pad can be attached to the bottom surface of the lower clamping plate 332 to increase the friction with the surface of the insulating cardboard, further improve the clamping effect, and at the same time avoid direct contact between the rigid board and the insulating cardboard, which may cause scratches on the surface of the insulating cardboard.

[0039] Specifically, in this embodiment, the X-axis sliding seat 13 of the pallet and the cutting table 1 are connected by a linear guide rail and a slider in a sliding fit. The corresponding linear guide rail is fixed to the bottom of the cutting table 1, and the corresponding slider is fixed to the top of the X-axis sliding seat 13 of the pallet. Since the linear guide rail and slider are existing conventional technologies, the sliding fit principle of the linear guide rail and slider will not be described in detail here and in the following content.

[0040] Specifically, in this embodiment, the Z-axis sliding seat 14 and the X-axis sliding seat 13 of the pallet are connected by a linear guide rail and a slider to form a sliding fit. The corresponding linear guide rail is fixed to the X-axis sliding seat 13 and extends vertically, and the corresponding slider is fixed to the Z-axis sliding seat 14 of the pallet. It should be noted that the shapes of the X-axis sliding seat 13 and the Z-axis sliding seat 14 of the pallet are not unique. According to the adaptive design, the main goal is to realize the longitudinal sliding of the X-axis sliding seat 13 and the vertical sliding of the Z-axis sliding seat 14.

[0041] Specifically, in this embodiment, multiple pallets 2 are transitionally connected to the pallet Z-axis sliding seat 14 via a pallet fixing platform 24. The multiple pallets 2 are fixedly connected to the pallet fixing platform 24 via any connection method such as welding, riveting, or fastener connection (bolt connection). The multiple pallets 2 are located at the top of the pallet fixing platform 24, and the bottom of the pallet fixing platform 24 is fixedly connected to the top of the pallet Z-axis sliding seat 14, using the same connection method as described above.

[0042] In this embodiment, the driving component used to move the X-direction sliding seat 13 of the pallet is any one of a cylinder, a hydraulic cylinder, or a lead screw motor; preferably, a first lead screw motor 91 is used in this embodiment. The first lead screw motor 91 is fixed on the cutting table bracket 11, and the threaded lead screw of the first lead screw motor 91 extends longitudinally, with its lead screw nut fixedly connected to the X-direction sliding seat 13 of the pallet. When the first lead screw motor 91 is started, the threaded lead screw rotates, driving the lead screw nut and the X-direction sliding seat 13 of the pallet fixed thereto to move longitudinally (X direction), thereby realizing the longitudinal position adjustment of the pallet 2. The model of the first lead screw motor 91 can be selected according to the total weight of the X-direction sliding seat 13 of the pallet, the Z-direction sliding seat 14 of the pallet, the pallet 2, and the insulating cardboard it carries, ensuring that its output torque and speed can meet the actual movement requirements. The lead screw motor drive has the advantages of high transmission accuracy, smooth operation, and precise position control, which is beneficial to improving the positioning accuracy of the pallet 2.

[0043] Specifically, in this embodiment, the driving component used to move the Z-direction sliding seat 14 of the pallet is any one of a cylinder, a hydraulic cylinder, or a lead screw motor; in this embodiment, a first cylinder 92 is preferably used. The cylinder body of the first cylinder 92 is fixed on the X-direction sliding seat 13 of the pallet, and its driving arm extends vertically upward, with the top end of the driving arm fixedly connected to the bottom of the Z-direction sliding seat 14 of the pallet. When the driving arm of the first cylinder 92 extends upward, it pushes the Z-direction sliding seat 14 of the pallet and the pallet 2 to rise vertically (in the Z direction); when the driving arm retracts downward, it drives the Z-direction sliding seat 14 of the pallet and the pallet 2 to descend. The stroke of the first cylinder 92 is set according to the height that the pallet 2 needs to lift the insulating paperboard and the space that needs to be avoided when descending. Its working pressure can be adjusted by the air source processor to adapt to the lifting requirements of insulating paperboards of different thicknesses and weights. The cylinder drive has the characteristics of fast response speed, simple structure, and convenient maintenance, and can quickly realize the lifting action of the pallet 2.

[0044] The structural design of tray 2 is as follows Figure 5As shown, the system includes a lifting section 21 for directly supporting the insulating cardboard, a connecting section 22 connecting the lifting section 21 and the pallet fixing platform 24, and a limiting section 23 located at the end of the lifting section 21 away from the cutter 32. The top surface of the lifting section 21 should be flat and smooth, and its length is determined according to the size of the cut insulating cardboard, generally slightly larger than the length of a single cut insulating cardboard sheet to ensure stable support. The limiting section 23 extends upward perpendicular to the top surface of the lifting section 21, and its function is to prepare and arrange the cut insulating cardboard for neatness before the lifting section 21 lifts it; the inner surface of the limiting section 23 is also smoothed to avoid scratching the insulating cardboard. The pallet 2 can be made of aluminum alloy or stainless steel. Aluminum alloy is lightweight and has a certain strength, while stainless steel has better corrosion resistance, and the choice can be made according to the working environment. Multiple pallets 2 are arranged at equal intervals in the transverse direction. The spacing between adjacent pallets 2 should ensure that the fork head 51 of the transfer fork plate 5 can be smoothly inserted without interfering with the pallet 2.

[0045] It is important to note that the clearance groove 12 on the cutting table 1 is positioned corresponding to the longitudinal movement path of the pallet 2. The width of the clearance groove 12 is slightly larger than the thickness of the pallet 2, and its length should cover the maximum travel range of the pallet 2 during longitudinal movement to ensure that the pallet 2 does not collide with the cutting table 1 during lifting and moving. The edges of the clearance groove 12 need to be chamfered and burrs removed to prevent it from being hooked or scratched during the conveying of the insulating cardboard.

[0046] Specifically, in this embodiment, the base mounting frame 41 of the material transfer mechanism is made of welded steel, such as square tubes or angle steel, and the bottom is fixed to the ground or equipment foundation by expansion bolts to ensure the stability of the material transfer mechanism during operation.

[0047] Specifically, in this embodiment, the material transfer Y-axis slide 42 and the base mounting frame 41 are connected by a linear guide rail and a slider in a sliding engagement. Specifically, the corresponding linear guide rail is fixed to the top of the base mounting frame 41, and the corresponding slider is fixed to the bottom of the material transfer Y-axis slide 42.

[0048] Specifically, in this embodiment, the driving component used to drive the Y-direction slide 42 to move is any one of a cylinder, a hydraulic cylinder, or a lead screw motor; in this embodiment, a second lead screw motor 93 is preferably used. The second lead screw motor 93 is fixed on the base mounting frame 41, and its threaded lead screw extends laterally (in the Y direction). The lead screw nut is fixedly connected to the lead screw slider mounting seat 421 at the bottom of the Y-direction slide 42. By rotating the second lead screw motor 93 forward and backward, the Y-direction slide 42 is driven to move laterally, thereby adjusting the lateral position of the transfer fork plate 5 so that it can be aligned with the cut insulating cardboard or the stacking platform 8.

[0049] Specifically, in this embodiment, the top of the Y-axis slide block 42 is provided with an upwardly extending Z-axis extension plate 422, and the Z-axis slide block 43 is slidably disposed on the Z-axis extension plate 422 in the vertical direction (Z direction). The two are also slidably engaged by a linear guide rail and a slider structure, that is, a vertically extending linear guide rail is fixed on the Z-axis extension plate 422, and a corresponding slider is fixed on the Z-axis slide block 43.

[0050] Specifically, in this embodiment, the driving component used to drive the Z-axis slide 43 of the material transfer is any one of a cylinder, a hydraulic cylinder, or a lead screw motor; in this embodiment, a third lead screw motor 94 is preferably used. The third lead screw motor 94 is fixed to the bottom of the Y-axis slide 42 of the material transfer or the top of the Z-axis extension plate seat 422, and its threaded lead screw extends vertically, with the lead screw nut fixedly connected to the Z-axis slide 43 of the material transfer. When the third lead screw motor 94 is working, it drives the Z-axis slide 43 of the material transfer to move vertically, realizing the lifting and lowering action of the transfer fork plate 5, so as to complete the action of receiving the insulating cardboard from the pallet 2 and placing the insulating cardboard on the stacking platform 8.

[0051] Specifically, in this embodiment, the transfer fork plate 5 is rotatably mounted on the Z-axis slide block 43 via a rotating shaft 54. In one specific implementation, multiple fork heads 51 within the transfer fork plate 5 are connected to a fork tail 52. The rotating shaft 54 ​​is fixed to the bottom of the fork tail 52. A bearing seat (not shown in the figure) is provided at the top of the Z-axis slide block 43 to cooperate with the rotating shaft 54. This bearing seat is preferably an axial bearing seat to ensure smooth rotation of the rotating shaft 54 ​​within the bearing seat and to support the weight of the transfer fork plate 5 and the insulating cardboard material it carries.

[0052] Specifically, in this embodiment, the driving component for driving the transfer fork plate 5 to rotate is a stepper motor, a servo motor, or a drive motor with a reduction mechanism. In this embodiment, a first drive motor 95 is preferably used. The first drive motor 95 is fixed on the Z-axis slide block 43, and its output shaft is connected to the rotating shaft 54 ​​through a coupling or gear transmission mechanism to drive the transfer fork plate 5 to rotate around the rotating shaft 54 ​​within a certain angle range. The rotation angle of the transfer fork plate 5 is set according to actual needs and is mainly used to rotate the horizontally supported insulating cardboard to the stacking angle required by the stacking platform 8. Taking the material transfer mechanism located directly behind the cutting table 1 and the stacking platform 8 located directly to the left or right of the material transfer mechanism as an example, the angle formed by the sequential lines connecting the cutting table 1, the material transfer mechanism, and the stacking platform 8 is 90 degrees. Therefore, when the transfer fork plate 5 receives the insulating cardboard behind the cutting table 1, it is in a horizontal state (0-degree angle). Before the transfer fork plate 5 moves laterally above the stacking platform 8, driven by the Y-axis slide 42, the first drive motor 95 drives the transfer fork plate 5 to rotate 90 degrees, aligning the insulating cardboard with the direction of the stacking platform 8, so that the insulating cardboard can be stably placed on the stacking platform 8. The rotation angle of the transfer fork plate 5 can be precisely controlled by setting an angle encoder on the output shaft or rotating shaft 54 ​​of the first drive motor 95, ensuring consistent rotation angle each time and improving the neatness of the stacking.

[0053] It should be noted that the fork head 51 is the part of the transfer fork plate 5 that directly inserts into the underside of the insulating cardboard. The width of the fork head 51 should be smaller than the distance between two adjacent pallets 2 so that it can be smoothly inserted into the gap between the pallets 2 and receive the insulating cardboard lifted by the pallets 2 from below. The front end of the fork head 51 should be designed with a smooth arc transition or a bevel to avoid scratching the insulating cardboard or the table surface of the cutting table 1 during insertion.

[0054] In this embodiment, the driving component for driving the unloading push plate 6 is any one of a cylinder, hydraulic cylinder, or lead screw motor; preferably, a second cylinder 96 is used in this embodiment. A cylinder fixing seat 53 is provided on the top of the fork tail 52, and the second cylinder 96 is fixed on the cylinder fixing seat 53. When the transfer fork plate 5 transfers the insulating cardboard to the top of the stacking platform 8 and lowers it to an appropriate height, the driving arm of the second cylinder 96 extends, pushing the unloading push plate 6 towards the stacking platform 8, pushing the insulating cardboard away from the transfer fork plate 5. A layer of rubber or silicone cushioning pad can be pasted on the pushing surface of the unloading push plate 6 (the side facing the insulating cardboard) to avoid impact or scratches on the surface of the insulating cardboard during the pushing process, while increasing the contact friction with the cardboard to ensure reliable pushing.

[0055] Furthermore, such as Figure 6 and Figure 7As shown, the bottom of the unloading push plate 6 is provided with an extension plate 61 extending to the space between two adjacent fork heads 51. The extension plate 61 serves two purposes: firstly, it acts as a guide, and secondly, it ensures that the insulating cardboard at the bottom (the insulating cardboard that is in direct contact with the fork head 51) can be pushed away smoothly.

[0056] Specifically, in this embodiment, the stacking platform 8 has an upwardly extending protective plate 81 on the side away from the transfer mechanism. An object sensor, such as an infrared sensor 7, is located at the bottom of the transfer fork plate 5. The infrared sensor 7 is preferably a diffuse reflection photoelectric sensor, and its sensing direction is the orientation of the top of the fork head 51. After the transfer fork plate 5 carrying the insulating cardboard moves above the stacking platform 8, it begins to descend, causing the transfer fork plate 5 and the insulating cardboard on it to gradually approach the already stacked insulating cardboard on the stacking platform 8 (e.g., ...). Figure 19 and Figure 20 As shown in the diagram, after the infrared sensor 7 located at the bottom of the transfer fork plate 5 detects the stacked insulating cardboard, the transfer fork plate 5 stops descending. At this time, the transfer fork plate 5 and the insulating cardboard on the transfer fork plate 5 are very close to the previously stacked insulating cardboard. At this time, the unloading push plate 6 is activated to push the insulating cardboard on the transfer fork plate 5 outward. During the pushing process, the moving distance of the unloading push plate 6 is determined according to the actual length of the insulating cardboard being cut. Taking the cutting length of the insulating cardboard as L as an example, the unloading push plate 6 stops when the distance between it and the front guard plate 81 is L. At this time, the two edges of the insulating cardboard on the transfer fork plate 5 are exactly in contact with the front guard plate 81 and the unloading push plate 6, respectively. Subsequently, the transfer slide 42 moves away from the stacking platform 8, while the unloading pusher 6 continues to push the insulating cardboard outward at the same speed as when it moved towards the transfer slide 42. Since the direction of movement of the transfer slide 42 and the unloading pusher 6 are opposite and their speeds are the same, the unloading pusher 6 remains stationary relative to the stacking platform 8. The transfer fork plate 5 gradually moves away from the stacking platform 8, thus creating the action of the transfer fork plate 5 gradually detaching from the insulating cardboard. Once the transfer fork plate 5 is completely detached from the insulating cardboard, the insulating cardboard above the transfer fork plate 5 is stacked precisely on top of the previously stacked insulating cardboard on the stacking platform 8. This stacking method of the insulating cardboard is not only neat but also does not damage the edges of the insulating cardboard (e.g., ...). Figure 23 As shown, if the insulating cardboard on the transfer fork plate 5 is pushed away and stacked directly from one side of the already stacked insulating cardboard, the unloading push plate 6 only needs to push the insulating cardboard away outwards, without the need for the transfer Y-axis slide 42 to retract, and the stacking operation can be completed. However, this stacking method is prone to relative displacement and friction between the corners of the bottommost pushed-away insulating cardboard and the already stacked insulating cardboard, which can easily cause damage to the bottommost pushed-away insulating cardboard and form burrs on the corners. Therefore, this stacking method is not recommended.

[0057] Furthermore, the top of the stacking platform 8 is provided with a side guard plate 82 located on the side of the front guard plate 81. One or two side guard plates 82 can be provided, and the specific arrangement is determined according to the method of later transferring the stacked insulating paperboard, with the main consideration being that the side guard plates 82 do not affect the later transfer of the stacked insulating paperboard. The main function of the side guard plates 82 is safety protection, reducing the risk of the stacked insulating paperboard tipping over.

[0058] Furthermore, such as Figure 8 and Figure 9 As shown, at least two stacking platforms 8 are provided and slidably disposed on one side of the transfer mechanism, and a drive assembly for driving all the stacking platforms 8 to move is also included.

[0059] As a specific implementation, taking two stacking platforms 8 as an example, the two stacking platforms 8 are fixedly connected by a transition connecting frame 83. The transition connecting frame 83 is welded from rectangular steel pipes, and its length is determined according to the distance between the two stacking platforms 8 to ensure connection strength and stability. The stacking platform 8 is connected to the corresponding ground or equipment foundation through a linear guide rail and a slider to form a sliding fit connection. The driving component used to drive the movement of the stacking platform 8 can be any one of a cylinder, hydraulic cylinder, or lead screw motor; in this embodiment, a second drive motor 97, which is an asynchronous motor, is preferred. A gear 84 is coaxially fixed on the power output shaft of the second drive motor 97, and a corresponding rack 85 is fixed on the corresponding ground or equipment foundation. The gear 84 meshes with the rack 85. When the second drive motor 97 is working, the meshing transmission between the gear 84 and the rack 85 drives the two stacking platforms 8 and the transition connecting frame 83 to slide along the linear guide rail as a whole. The purpose of setting up two stacking platforms 8 is to achieve continuous operation. When the insulating cardboard on one stacking platform 8 reaches a preset quantity or height, the platform 8 is moved so that the other empty platform 8 moves under the transfer fork plate 5 to continue receiving the transferred insulating cardboard. The full stacking platform 8 can be unloaded or processed on the side, avoiding the impact on the continuous operation efficiency of the equipment due to waiting for unloading. The travel distance of the stacking platform 8 can be controlled by setting limit switches (such as proximity switches or limit switches) at both ends of its sliding path. When the stacking platform 8 moves to the preset position, the limit switch triggers a signal to the control system, which then controls the second drive motor 97 to stop working, ensuring the positioning accuracy of the stacking platform 8.

[0060] It should be noted that all driving components involved in this invention (such as cylinders, hydraulic cylinders, lead screw motors, drive motors, conveyors, infrared sensors, etc.) are electrically connected to the equipment's control system (such as a PLC controller). The coordinated control of each component's actions is achieved through a preset program in the control system. For example, when the conveyor 10 transports the insulating cardboard to a predetermined position on the cutting table 1, the control system sends a signal to the corresponding driving component, causing the clamping member 33 to descend and clamp the insulating cardboard. After clamping, the control system controls the corresponding driving component to cause the cutter 32 to descend and cut. After cutting, the cutter 32 ascends to reset, and the clamping member 33 ascends to release, etc. The control system can also be equipped with a human-machine interface (such as a touchscreen), allowing operators to set cutting dimensions, adjust the operating parameters of each driving component, monitor equipment operating status and fault alarms, etc., thereby improving the equipment's ease of operation and intelligence. The aforementioned control system (such as a PLC controller) is prior art, and the specific parameter adjustment methods will not be elaborated here.

[0061] In addition, to ensure safe operation of the equipment, safety guards should be installed on the outside of moving parts such as the cutting mechanism and material transfer mechanism. These guards should be made of metal mesh or transparent acrylic sheets, ensuring that they do not obstruct observation of the equipment's operation while effectively preventing operators from coming into contact with the moving parts and causing injury. A safety interlock device should be installed on the guards; when the guards are opened, the equipment should immediately stop operating and can only restart after the guards are closed, further enhancing the equipment's safety performance. The safety guards can be adapted to the actual installation conditions of the device at the site; the design of the guards is not within the scope of the technical problems addressed in this invention, and specific installation methods will not be elaborated upon.

[0062] Instructions for using an insulating paper shearing machine for transformer production: First, it should be noted that the entire operation process of the device is cyclical when cutting insulating paperboard. For ease of understanding, the starting point of this working principle description is the working state when a piece of insulating paperboard has just been cut.

[0063] like Figure 11 As shown, under the pressing action of the clamping member 33, the cutter 32 cuts a section of insulating cardboard and returns to its working position; the lifting part 21 of the pallet 2 is in the clearance groove 12 and located below the surface of the cutting table 1, and the cut insulating cardboard is located directly above the corresponding lifting part 21 in the pallet 2; the Y-direction transfer slide 42 is located on the side away from the conveyor 10, and the Z-direction transfer slide 43 is located at the lowest working position. At this time, the transfer fork plate 5 is located above the cutting table 1 and close to the upper surface of the cutting table 1, with the fork head 51 facing the position of the pallet 2, and the unloading push plate 6 is close to the side of the fork tail 52.

[0064] Next step (such as) Figure 12As shown): The drive arm of the first cylinder 92 extends and pushes the tray Z towards the sliding seat 14 and the tray 2 to move upward. The corresponding lifting part 21 in the tray 2 moves to above the upper surface of the cutting table 1. At the same time, the lifting part 21 lifts up the cut insulating cardboard. At this time, the height of all the insulating cardboard at the top of the lifting part 21 is higher than the height of the fork head 51.

[0065] Next step (such as) Figure 13 As shown): The first lead screw motor 91 drives the tray X to slide the seat 13 towards the position of the fork head 51 through the corresponding lead screw nut. While the tray X moves towards the slide seat 13, it also moves the tray 2 and the insulating cardboard above the tray 2 until the insulating cardboard is completely moved above the fork head 51, completing the transfer preparation action of the insulating cardboard.

[0066] Next step (such as) Figure 14 (As shown): The third lead screw motor 94 drives the material transfer Z to move upward toward the slide block 43 via the corresponding lead screw nut. At the same time, the drive arm of the first cylinder 92 retracts and drives the pallet Z to move downward toward the slide block 14 and the pallet 2. During this process, when the height of the fork head 51 exceeds the height of the lifting part 21, the insulating cardboard on the lifting part 21 is transferred to the fork head 51. When the lifting part 21 descends back to a height below the cutting table 1, it stops. When the material transfer Z moves to the slide block 43 to its maximum height, it stops. At this time, the transfer fork plate 5 and the insulating cardboard on top of the fork head 51 are at their highest working height. At the same time, the clamping part 33 rises, releasing the positioning of the insulating cardboard to be cut, preparing to cut the insulating cardboard again.

[0067] Next step (such as) Figure 15 As shown): The conveyor 10 starts and moves the insulating cardboard to be cut onto the cutting table 1. The conveying length of the conveyor 10 is the length of the insulating cardboard to be cut.

[0068] At the same time, the first drive motor 95 drives the rotating shaft 54 ​​to rotate, thereby driving the transfer fork plate 5 and the insulating cardboard located on the top of the fork head 51 to rotate until the fork head 51 is aligned with the direction of the stacking platform 8.

[0069] Next step (such as) Figure 16 and Figure 17 As shown): the clamping element 33 descends again and clamps the insulating cardboard to be cut.

[0070] At the same time, the second lead screw motor 93 drives the Y-direction slide block 42 to move towards the stacking platform 8 through the corresponding lead screw nut. The Y-direction slide block 42, along with the Z-direction slide block 43, the transfer fork plate 5, and the insulating cardboard located on the top of the fork head 51, moves upward to the stacking platform 8 until the top of the fork head 51 is close to the inner wall of the positive guard plate 81.

[0071] Next step (such as) Figure 18 As shown): the cutter 32 moves downward and cuts the insulating cardboard to be cut.

[0072] At the same time, the third lead screw motor 94 drives the material transfer Z to move downward to the slide block 43 through the corresponding lead screw nut, so that the transfer fork plate 5 and the insulating cardboard located on the top of the fork head 51 gradually approach the insulating cardboard that has been stacked on the stacking platform 8.

[0073] Next step (such as) Figures 19 to 20 As shown): After the infrared sensor 7 located at the bottom of the transfer fork plate 5 detects the stacked insulating cardboard, the transfer fork plate 5 stops descending. At this time, the transfer fork plate 5 and the insulating cardboard on the transfer fork plate 5 are very close to the previously stacked insulating cardboard. The unloading push plate 6 is activated to push the insulating cardboard on the fork head 51 outward. During the pushing process, the moving distance of the unloading push plate 6 is determined according to the actual length of the insulating cardboard being cut. Taking the cutting length of the insulating cardboard as L as an example, the unloading push plate 6 stops when the distance between it and the front guard plate 81 is L. At this time, the two edges of the insulating cardboard on the fork head 51 are exactly in contact with the front guard plate 81 and the unloading push plate 6, respectively.

[0074] Next step (such as) Figure 21 As shown): The Y-direction slide 42 moves away from the stacking platform 8, while the unloading push plate 6 continues to push the insulating cardboard away from it at the same speed as the Y-direction slide 42. Since the Y-direction slide 42 moves in the opposite direction to the unloading push plate 6 and moves at the same speed, the unloading push plate 6 is stationary relative to the stacking platform 8. The fork head 51 gradually moves away from the stacking platform 8, which forms the action of the fork head 51 gradually separating from the insulating cardboard. After the fork head 51 is completely separated from the insulating cardboard, the insulating cardboard above the transfer fork plate 5 is just stacked on the insulating cardboard that was originally stacked on the stacking platform 8.

[0075] At the same time, the cutter 32 rises, leaving space for the cardboard to be cut to re-enter the cutting table 1.

[0076] Next step (such as) Figure 22 As shown): The first lead screw motor 91 drives the X-direction sliding seat 13 of the support plate to move in the direction of the cutter 32 through the corresponding lead screw nut until the lifting part 21 is directly below the cut insulating cardboard.

[0077] At the same time, the Z-axis slide 43 of the material transfer descends, and the transfer fork plate 5 rotates back to face the pallet 2.

[0078] At this point, all component workstations are restored to their normal state. Figure 11 The initial state, and complete a cutting-transfer-stacking process for insulating cardboard.

[0079] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
