Description

Technical Field

[0001] This invention relates to the field of insulating steel paper forming technology, specifically to an insulating steel paper hot-pressing composite flattening forming device. Background Technology

[0002] After the semi-finished insulating steel paper is impregnated and gelled, its internal fiber structure is relatively loose and contains a certain amount of moisture. It must undergo continuous and precise hot pressing and leveling processes to form a finished product with a dense structure and satisfactory insulation performance. Traditional hot pressing equipment has shortcomings in structural design and process coordination in multi-layer paper web composite processing. In the feeding stage, the equipment generally lacks an automatic lateral offset correction mechanism, which causes paper webs with initial tension differences, feeding skew, or local wrinkles to directly enter the hot pressing zone. Under such conditions, hard pressing will cause misalignment, local bias, and interlayer voids between multiple layers of materials, which will seriously damage the density of the internal structure of the board.

[0003] During the hot-press curing process, the high temperature and pressure inevitably cause the adhesive between the paper layers to be squeezed outwards and hardened on the work panel to form stubborn adhesive residue and carbon deposits. Existing equipment relies on manual periodic shutdowns for scraping. This operation not only disrupts the rhythm of continuous production and reduces equipment uptime, but also makes it difficult to ensure thorough cleaning by hand. The remaining tiny hardened adhesive lumps will leave indentations and pits on the surface of the steel paper in subsequent continuous production. These micro-defects can become hidden dangers of partial discharge in electrical applications, leading to fluctuations or even failure of the overall insulation strength of the finished product.

[0004] Furthermore, the insulating steel paper accumulates significant thermal stress after undergoing high-temperature hot pressing, requiring stable constraint and gradual release during the subsequent cooling and unloading stage. Existing unloading traction mechanisms employ fixed-axis roller drive structures, which cannot dynamically and adaptively adjust to the minute thickness fluctuations that occur in the multi-layer composite board. When the board entering the traction roller is too thin, the fixed-gap traction mechanism will slip, causing the board's dwell time in the machine to become uncontrolled. Conversely, when the board is too thick, it will be subjected to excessive compression, damaging the surface flatness of the newly formed material. This lack of flexibility in mechanical pulling and compression will induce irregular release of internal stress in the board, ultimately leading to irreparable edge wavy lines and overall warping deformation after the finished product has completely cooled. This makes it difficult to meet the technical requirements of high flatness and high dimensional stability for precision electrical insulation materials. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an insulating steel paper hot-pressing composite flattening forming device, which solves the problems of feed deviation, difficulty in cleaning residual adhesive residue on the working surface, and warping and deformation of finished products caused by the inability of the traction roller to adapt to changes in the thickness of the sheet material in existing insulating steel paper hot-pressing equipment.

[0009] Preferably, the traction mechanism includes a placement box and a support block. Both the placement box and the support block are fixedly connected to the top of the base.

[0016] This invention provides an insulating steel paper hot-pressing composite flattening forming device. It has the following beneficial effects: 1. This invention, by setting up a traction mechanism, utilizes a third motor to drive a rotating shaft. The convex block on the outer side of the rotating shaft is slidably connected to the second bevel gear, allowing the second bevel gear to maintain the transmission of rotational power while moving up and down. Simultaneously, the end of the second traction roller slides within a groove. Combined with the downward tension provided by the tension spring and the bracket, the second traction roller can adaptively float and press according to the different thicknesses of the insulating steel paper after molding. This ensures synchronous transmission of the upper and lower traction rollers while preventing traction slippage or damage to the sheet material due to excessive local pressure, thus improving the stability of the output.

[0017] 2. This invention features a cleaning mechanism that uses a second motor to drive an eccentric wheel to rotate. The rotational motion of the eccentric wheel is converted into linear reciprocating motion of a slider within a groove on a fixed plate via a connecting rod. This motion, in turn, drives a scraper to continuously scrape the hot-pressing surface. The scraped-off adhesive residue falls directly into an outer collection box for centralized processing. Simultaneously, it can automatically clean residual adhesive and impurities on the working surface during equipment operation intervals, preventing indentations on the steel paper surface during subsequent pressing and ensuring the smoothness of the finished board surface.

[0018] 3. This invention, by setting up a correction mechanism, uses a first motor to drive the main gear to mesh with the rack at the bottom of the placement plate, converting the rotational power of the motor into the lateral linear displacement of the placement plate. With the guidance and limiting of the guide rail, the top guide roller is driven to perform lateral translational movement. At the same time, it can correct the lateral offset of the insulating steel paper in real time during the feeding stage, ensuring that the multi-layer paper web can enter the preheating and hot pressing station straight and aligned, reducing the problems of board surface wrinkles and composite misalignment caused by feeding skew.

[0021] The technical solutions in 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.

[0022] Please see the appendix Figure 1 This invention provides an insulating steel paper hot-pressing composite flattening forming device, including a base 1. A correction mechanism 3 is installed on the top of the base 1 to correct the lateral deviation of the insulating steel paper, ensuring it enters the machine straight. A preheating box 4 is fixedly connected to one side of the correction mechanism 3 on the top of the base 1. A fixing plate 5 is fixedly connected to the top of the base 1, and a cleaning mechanism 9 is installed inside the fixing plate 5 to clean impurities and adhesive residue from the working surface. Multiple gradient coolers 11 are fixedly connected to the top of the base 1, and a traction mechanism 12 is installed on the top of the base 1 to smoothly pull and flatten the formed steel paper. Multiple support columns 6 are fixedly connected to the top of the fixing plate 5, and a top plate 8 is fixedly connected to the top of the multiple support columns 6. Multiple cylinders 10 are fixedly connected to the bottom of the top plate 8, and a hot-pressing plate 7 is fixedly connected to the output end of the multiple cylinders 10. A railing 2 is fixedly connected to the outer side of the base 1. The correction mechanism 3, preheating box 4, fixing plate 5, gradient coolers 11, and traction mechanism 12 are arranged in a linear array along the longitudinal centerline of the base 1. Specifically, during the hot-pressing and leveling operation of insulating steel paper, the multi-layer impregnated semi-finished product passes through each processing station sequentially along the longitudinal centerline of the base 1 at a speed of 4 to 12 m / min. First, the feeding position is corrected by the front-end correction mechanism 3. Then, the insulating steel paper enters the preheating box 4 at a uniform speed for constant temperature preheating at 60 to 80°C to eliminate residual moisture and internal stress on the paper surface. Next, multiple cylinders 10 extend downwards to drive the hot-pressing plate 7 to cooperate with the fixing plate 5 below to complete the high-temperature and high-pressure pressing. At this time, the working temperature of the hot-pressing plate 7 and the fixing plate 5 is controlled between 120 and 160°C. A working pressure of 0.4 to 1.0 MPa is applied uniformly throughout the entire area, and the pressure holding and curing time is set to 3 to 10 seconds to fully cross-link and composite the multi-layer steel paper fibers and compact the gaps between the layers. After pressure holding and curing, the steel paper passes through multiple gradient coolers 11 for segmented slow cooling and temperature reduction, gradually releasing stress and shaping it according to the first section 90℃, the middle section 60℃, and the last section 40℃. Finally, the traction mechanism 12 at the tail end provides smooth traction and output. The entire system has temperature and pressure linkage control and overpressure and overtemperature safety interlock emergency stop functions. The outer railing 2 is used for safety protection and isolation of the high temperature and high pressure operating area.

[0023] Please see the appendix Figure 2In a preferred embodiment of the present invention, the correction mechanism 3 includes a base plate 31, which is fixedly connected to the top of the base 1. A first motor 32 is fixedly connected to the bottom of the base plate 31. A rotating shaft 33 is fixedly connected to the output end of the first motor 32. A main gear 34 is fixedly connected to the outside of the rotating shaft 33. Two guide rails 35 are fixedly connected to the top of the base plate 31. A guide strip 37 is slidably connected to the outside of the guide rails 35. A placement plate 36 is fixedly connected to the top of the guide strip 37. A rack 38 is fixedly connected to the outside of the guide strip 37. The rack 38 meshes with the main gear 34. Two guide rollers 39 are rotatably connected to the top of the placement plate 36. The guide rails 35 are arranged laterally and perpendicular to the paper feeding direction. Specifically, when the feeding deviates, the first motor 32 is started to drive the rotating shaft 33 and the main gear 34 to rotate. The main gear 34 moves the rack 38 that meshes with it, causing the bottom guide bar 37 to slide in the horizontally set guide rail 35. The linear motion causes the placement plate 36 and the two top guide rollers 39 to move laterally as a whole, thereby correcting the lateral deviation of the insulating steel paper web in real time, smoothing out the paper surface wrinkles, and ensuring that the multi-layer paper web can enter the subsequent hot pressing station flat and straight, avoiding local indentation or bias defects.

[0024] Please see the appendix Figure 3 - Appendix Figure 5 In a preferred embodiment of the present invention, the cleaning mechanism 9 includes a collection box 91, which is fixedly connected to the outside of the fixed plate 5. A second motor 92 is fixedly connected to the top of the base 1. An eccentric wheel 93 is fixedly connected to the output end of the second motor 92. A fixed rod 94 is fixedly connected to the eccentric position at the top of the eccentric wheel 93. A connecting rod 95 is rotatably connected to the outside of the fixed rod 94. A slider 97 is rotatably connected to the other end of the connecting rod 95. A groove 96 is provided inside the fixed plate 5. A scraper 98 is fixedly connected to the outside of the slider 97. The slider 97 is slidably connected inside the groove 96. The bottom of the scraper 98 is in contact with the top surface of the fixed plate 5. Specifically, during equipment operation breaks or cleaning shutdowns, the second motor 92 is started to rotate the eccentric wheel 93. The fixed rod 94 eccentrically arranged on the eccentric wheel 93 drives the connecting rod 95 to swing back and forth. The connecting rod 95 transmits the motion to the slider 97, forcing the slider 97 to slide linearly back and forth in the groove 96 in the fixed plate 5. Since the bottom of the scraper 98 is in close contact with the top surface of the fixed plate 5, the slider 97 drives the scraper 98 to scrape back and forth on the working surface, pushing the residual paper dust, glue residue and impurities into the collection box 91 on the side for centralized collection, thereby maintaining the smoothness of the hot pressing working surface and ensuring the surface quality and insulation performance of the finished product.

[0025] Please see the appendix Figure 6 - Appendix Figure 8In a preferred embodiment of the present invention, the traction mechanism 12 includes a placement box 121 and a support block 122. Both the placement box 121 and the support block 122 are fixedly connected to the top of the base 1. A third motor 123 is fixedly connected to the top of the placement box 121. A rotating shaft 124 is fixedly connected to the output end of the third motor 123. A first bevel gear 125 is fixedly connected to the outer side of the rotating shaft 124, and a second bevel gear 128 is slidably connected to the outer side of the rotating shaft 124. A first traction roller 127 is rotatably connected inside the placement box 121. A first transmission wheel 126 is fixedly connected to the outer side of the first traction roller 127. A second traction roller 1210 is slidably connected inside the placement box 121. A second transmission wheel 129 is fixedly connected to the outer side of the second traction roller 1210. The first transmission wheel 126 and the first bevel gear 125... The second drive wheel 129 meshes with the second bevel gear 128; a bracket 1211 is sleeved on the outside of the second traction roller 1210, a connecting plate 1212 is fixedly connected to the outside of the placement box 121, a tension spring 1213 is fixedly connected to the bottom of the connecting plate 1212, and the bottom end of the tension spring 1213 is fixedly connected to the top of the bracket 1211. The bracket 1211 is used to provide downward compressive force to the second traction roller 1210; a groove 1215 is opened on the inner side of the support block 122, the first traction roller 127 is rotatably connected to the inside of the support block 122, and the end of the second traction roller 1210 away from the placement box 121 is slidably connected to the inside of the groove 1215; a protrusion 1214 is fixedly connected to the outside of the rotating shaft 124 near the top, and the second bevel gear 128 is slidably connected to the outside of the protrusion 1214; Specifically, during the traction discharge, the third motor 123 drives the rotating shaft 124 to rotate, and the first bevel gear 125 below drives the first transmission wheel 126 to rotate the first traction roller 127. When the formed steel paper enters the roller gap, one end of the second traction roller 1210 floats upward along the groove 1215 of the support block 122 to adapt to the thickness of the board. At the same time, the second bevel gear 128 at the other end slides upward along the protrusion 1214 of the rotating shaft 124, so that it can still maintain meshing with the second transmission wheel 129 and synchronously transmit rotational power during the up and down floating process. At this time, the connecting plate 1212 at the top provides a continuous downward pressing force to the support 1211 and the second traction roller 1210 below through the tension spring 1213, realizing adaptive pressure stabilization and uniform speed traction output for steel paper of different thicknesses.

[0026] Working Principle: When using the equipment, the semi-finished insulating steel paper is first introduced into the front section of the equipment. Then, the correction mechanism 3 set on the top of the base 1 is activated to correct the lateral deviation of the insulating steel paper and ensure that it enters the machine straight. Next, the steel paper enters the preheating box 4 at a uniform speed for preheating treatment to eliminate residual moisture and internal stress. After preheating, the steel paper moves to the top of the fixed plate 5, and the cylinder 10 at the bottom of the top plate 8 is activated to drive the hot press plate 7 to move downward, so as to perform high temperature and high pressure bonding and flattening of the multi-layer insulating steel paper. After pressure holding and curing, the cylinder 10 drives the hot press plate 7 to reset and rise. During the hot pressing interval, the cleaning mechanism 9 inside the fixed plate 5 can be activated to scrape and clean the overflow glue and impurities on the working surface. Then, the flattened steel paper moves into the gradient cooler 11 for segmented slow cooling and pressure stabilization to lock the flatness of the plate surface. Finally, the traction mechanism 12 at the tail end of the base 1 is activated to smoothly pull out the formed insulating steel paper, completing the entire continuous hot pressing composite flattening process.

[0027] When correcting the lateral deviation of the insulating steel paper, the first motor 32 at the bottom of the base plate 31 is started, which drives the rotating shaft 33 and the main gear 34 to rotate. The main gear 34 meshes with the rack 38 fixed at the bottom of the placement plate 36, converting the rotational motion into linear motion. This causes the guide bar 37 on one side of the rack 38 to slide laterally on the outside of the guide rail 35. At the same time, it causes the placement plate 36 and the two guide rollers 39 at the top to move laterally, thereby automatically correcting the lateral deviation of the insulating steel paper web. When cleaning the residual glue and impurities on the hot-pressed working surface, start the second motor 92 fixed at the top of the base 1, drive the eccentric wheel 93 to rotate, and cause the fixed rod 94 fixed at the eccentric position to drive the connecting rod 95 connected to the outside to swing back and forth. Then, through the connecting rod 95, drive the slider 97 at the other end to slide back and forth in a linear groove 96 opened inside the fixed plate 5. This causes the scraper 98 fixed on the outside of the slider 97 to scrape back and forth on the top surface of the fixed plate 5, pushing the impurities and glue into the collection box 91 on the outside of the fixed plate 5 for centralized collection. When insulating steel paper of different thicknesses is smoothly pulled, the third motor 123 on the top of the placement box 121 is started, which drives the rotating shaft 124 to rotate, thereby driving the first bevel gear 125 fixed on the outside of the rotating shaft 124 to rotate, and causing the second bevel gear 128 to rotate synchronously on the outside of the protrusion 1214. The first bevel gear 125 drives the meshing first transmission wheel 126 and the first traction roller 127 at the bottom to rotate. At the same time, the insulating steel paper enters between the first traction roller 127 and the second traction roller 1210. One end of the second traction roller 1210 slides upward inside the groove 1215 to adapt to the thickness of the steel paper. At this time, the tension spring 1213 at the bottom of the connecting plate 1212 provides downward compressive force to the second traction roller 1210 through the bracket 1211, and the second bevel gear 128 slides upward on the outside of the protrusion 1214 to keep the transmission uninterrupted. The second bevel gear 128 drives the meshing second transmission wheel 129 and the second traction roller 1210 to rotate synchronously, thereby realizing adaptive pressing and smooth traction leveling of the steel paper.
