Description

Technical Field

[0001] This invention relates to the field of cotton pressing machine technology, and in particular to an intelligent cotton pressing machine for pressing and adjusting the thickness of multi-layer composite materials. Background Technology

[0002] In fields such as new energy vehicles, consumer electronics, and aerospace, the demand for multilayer composite thermal insulation materials is growing. Among them, composite thermal insulation films with aerogel, ceramic cotton, etc. as the core layer and polymer film and other surface materials are widely used. The cotton pressing process is the core link in the production of multilayer composite materials. It directly determines the initial density, thickness and uniformity of the core layer material and is a key step that affects the performance of the final product.

[0003] Traditional cotton pressing equipment mostly uses mechanical rigid roller structures, which mainly achieve material compaction through the fixed gap or constant pressure of one or more pairs of parallel rollers. The thickness adjustment capability is limited, and the roller gap can usually only be changed manually or by a coarse adjustment mechanism. It cannot dynamically compensate for the uneven thickness of the cotton blank, resulting in poor thickness consistency of the finished product. Secondly, for loose and highly elastic fiber materials, traditional rigid pressing is prone to causing hard crushing or rebound of the fibers, resulting in uneven fiber distribution. It is difficult to achieve gradual and uniform compaction from shallow to deep, and it is difficult to eliminate internal stress. The product is prone to thickness rebound and deformation during subsequent processing or use. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an intelligent cotton pressing machine for multi-layer composite material pressing and thickness adjustment. It solves the technical problems of existing cotton pressing equipment being unable to dynamically compensate for uneven cotton blank thickness and having difficulty eliminating internal stress during the pressing process. It has the advantages of achieving high-precision thickness control and effectively suppressing material rebound.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an intelligent cotton pressing machine for multi-layer composite material pressing and thickness adjustment, comprising a housing, wherein an adaptive pressure roller mechanism and a zoned pressing mechanism are arranged inside the housing, a cotton material guiding mechanism is arranged on the feeding side of the housing, and a thickness measuring and correction mechanism is arranged on the discharging side of the housing. After the rolled pre-made cotton blank enters the housing, the adaptive pressure roller mechanism and the zoned pressing mechanism will press the cotton blank, and then the cotton blank will be discharged from the other side of the housing. During the discharge process, the thickness measuring and correction mechanism... The thickness of the pressed cotton blank will be detected. The adaptive pressure roller mechanism includes a pre-pressing component, a fine pressing component, and a shaping component. The fine pressing component is located between the pre-pressing component and the shaping component. The pre-pressing component includes a fixed steel roller and a lower pressing steel roller is arranged above the fixed steel roller. The inside of the box is symmetrically provided with side wall vertical grooves. A lower pressing protrusion is slidably connected inside the side wall vertical groove. The lower pressing steel roller is rotatably connected to the lower pressing protrusion. The pre-pressing component is used to initially compact the cotton blank. The lower pressing steel roller can move up and down along the side wall vertical groove, which can adapt to materials with different initial thicknesses.

[0006] Preferably, the interior of the vertical groove of the side wall is provided with a hydraulic push rod that drives the pressing protrusion to move up and down, and the exterior of the pressing steel roller is covered with a shallow toothed rubber sleeve, which can break up the cotton fiber clumps while initially compacting the incoming material, making them more evenly distributed, rather than simply flattening them.

[0007] Preferably, the precision pressing assembly includes a primary hydraulic rod fixedly mounted on the housing, an arc-shaped bracket fixedly mounted at the lower end of the primary hydraulic rod, a plurality of planetary pressure rollers movably mounted on the arc-shaped bracket, an adjustment groove provided on the side wall of the arc-shaped bracket, a fine-tuning slider slidably connected inside the adjustment groove, the fine-tuning slider being rotatably connected to the end of the planetary pressure rollers, and a secondary hydraulic rod provided inside the adjustment groove, the secondary hydraulic rod being used to drive the fine-tuning slider to move along the adjustment groove, thereby adjusting the local pressing amount.

[0008] Preferably, the shaping component includes a lower cooling roller and an upper cooling roller. Both the lower cooling roller and the upper cooling roller have liquid storage cavities inside. A liquid filling pipe is provided on the outside of the box body. The liquid filling pipe is connected to the liquid storage cavity. During the pressing of the cotton blank, cooling water can circulate into the liquid storage cavity through the liquid filling pipe, thereby ensuring that the surfaces of the lower cooling roller and the upper cooling roller are in a low temperature state.

[0009] Preferably, the partitioned pressurization mechanism includes symmetrically arranged mounting frames, on which alloy steel shafts are movably mounted. A pressure chamber is fixedly mounted on the outside of the alloy steel shaft, and an internal oil passage is coaxially opened inside the alloy steel shaft, which communicates with the pressure chamber. One mounting frame is provided with a hydraulic oil circuit, and a rotary connector is provided between the hydraulic oil circuit and the internal oil passage. A drive motor is fixedly mounted on the other mounting frame. The drive motor is used to rotate the alloy steel shaft at a constant speed. During the rotation of the alloy steel shaft, the hydraulic oil circuit can still input hydraulic oil into the internal oil passage.

[0010] Preferably, a piston assembly is movably installed inside the pressure chamber. One end of the piston assembly is slidably and sealed to the pressure chamber, and the other end of the piston assembly is fixedly installed with a wear-resistant bushing. The wear-resistant bushing is made of highly elastic, highly wear-resistant, and high-temperature resistant polyurethane or engineering ceramic composite material. Multiple wear-resistant bushings are tightly spliced ​​together to form a complete and smooth cylindrical working surface.

[0011] Preferably, the cotton material guiding mechanism includes a lightweight frame fixedly installed on the feeding side of the box body. Floating grooves are symmetrically opened on the lightweight frame. A wedge-shaped guide block is slidably connected to the lightweight frame. Fixed protrusions are symmetrically arranged on both sides of the wedge-shaped guide block. The fixed protrusions are slidably connected to the floating grooves. Initially, the wedge-shaped guide block will be located at the lower end of the floating groove under the action of gravity.

[0012] Preferably, the bottom surface of the wedge-shaped guide block is a bidirectional inclined wedge-shaped surface. From the feeding direction, the bottom surface is an inclined uphill surface, which is used to guide the cotton blank into the pressure roller biting area. From the middle to both sides, the bottom surface is a slightly convex arc-shaped surface that is high in the middle and low on both sides, which can generate a continuous, gentle stretching force on the cotton blank to both sides.

[0013] Preferably, the thickness correction mechanism includes a detection platform fixedly installed on the outlet side of the box. A mounting groove is provided on the outer side of the box. A ball screw is movably installed inside the mounting groove. A reciprocating slider is threaded to the outside of the ball screw. The pressed cotton blank will pass through the top of the detection platform. During this process, the reciprocating slider will move back and forth under the drive of the ball screw.

[0014] Preferably, a scanning beam is fixedly installed on the reciprocating slider, and a thickness sensor is provided on the scanning beam. During the back-and-forth movement of the scanning beam, the thickness sensor automatically measures the thickness of the cotton blank.

[0015] By employing the above technical solution, the present invention provides an intelligent cotton pressing machine for pressing and adjusting the thickness of multi-layer composite materials, which has at least the following beneficial effects: 1. This invention achieves progressive pressing from coarse to fine by setting an adaptive pressure roller mechanism. The pre-pressing component is used for initial pressing and fiber combing, the fine pressing component is used for high-precision molding, and the shaping component is used to suppress material springback. This can effectively ensure that the finished product has uniform thickness and dense structure, and significantly improve the consistency and stability of product performance.

[0016] 2. This invention, by setting an adaptive pressure roller mechanism, adopts a two-stage adjustment mechanism: a first-stage hydraulic rod controls the overall gap, and a second-stage hydraulic rod independently fine-tunes each planetary pressure roller. This enables the equipment to not only set a macroscopic pressing benchmark, but also to dynamically and independently compensate for thickness deviations in different areas of the cotton blank, thereby achieving precise control of the finished product thickness and solving the technical bottleneck of uneven thickness in traditional equipment.

[0017] 3. By setting an adaptive pressure roller mechanism, the shaping component can quickly cool and compact the cotton blank immediately after pressing. This can quickly eliminate the internal stress and elastic recovery tendency of the material caused by frictional heat, and prevent the finished product from deforming and changing in thickness during subsequent processing or storage. This fundamentally ensures the dimensional accuracy and long-term stability of the final product.

[0018] 4. By setting up a partitioned pressurization mechanism, the present invention can precisely coordinate with the planetary pressure rollers of the upper precision pressing component to form an intelligent clamping of upper pressure and lower push. When the output cotton blank is detected to be too thick, the upper and lower pressures are increased simultaneously to achieve efficient local compaction, which greatly improves the response speed and homogenization effect of thickness compensation.

[0019] 5. By setting up a partitioned pressurization mechanism, the pressure chamber is integrated into the pressure roller, and dynamic sealing oil supply is achieved through a rotary joint. This ensures that the equipment can still perform precise pressure partition control during continuous operation. Furthermore, the outer high-elasticity wear-resistant bushing can convert discrete piston thrust into a continuous and smooth radial pressure distribution, which can avoid damage to the cotton blank surface caused by sudden pressure changes.

[0020] 6. By setting up a cotton material guiding mechanism, the present invention utilizes the cooperation between the wedge-shaped guide block and the floating groove to intelligently pre-process the cotton blank without external power. This can optimize the feeding angle to avoid jamming and automatically eliminate slight wrinkles and edge curling of the cotton blank through the stretching force to both sides. This ensures that the material entering the main pressing zone is flat and has uniform stress from the source, laying an ideal foundation for subsequent high-precision pressing.

[0021] 7. By setting up a thickness correction mechanism, the present invention uses a high-precision ball screw to drive the thickness sensor to perform full-width reciprocating scanning, which enables online and real-time measurement of the thickness of the finished product. Furthermore, the collected data is immediately fed back to the control system, driving the adaptive pressure roller mechanism and the zoned pressure mechanism to make dynamic adjustments. This transforms the traditional post-production sampling inspection into precise process control, greatly improving the level of intelligent production and the product qualification rate.

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] Example 1 Traditional cotton pressing equipment mostly uses a mechanical rigid roller structure, which achieves material compaction mainly through the fixed gap or constant pressure of one or more pairs of parallel rollers. Its thickness adjustment capability is limited, usually only allowing manual or coarse adjustment mechanisms to change the roller gap. It cannot dynamically compensate for uneven cotton thickness, resulting in poor finished product thickness consistency. Secondly, for loose, highly elastic fiber materials, traditional rigid pressing easily causes fiber crushing or rebound, leading to uneven fiber distribution and making it difficult to achieve gradual, uniform compaction from shallow to deep. Furthermore, it is difficult to eliminate internal stress, making the product prone to thickness rebound and deformation during subsequent processing or use. To address these technical shortcomings in existing technology, such as... Figures 1-7 As shown in the figure, this embodiment proposes an intelligent cotton press for multi-layer composite material pressing and thickness adjustment, which can achieve high-precision thickness control and effectively suppress material rebound. The cotton press includes a box 1, inside which is set an adaptive pressure roller mechanism 2 and a zoned pressure mechanism 3. A cotton material guiding mechanism 4 is set on the feeding side of the box 1, and a thickness measurement and correction mechanism 5 is set on the discharging side of the box 1. After the rolled pre-made cotton blank enters the box 1, the adaptive pressure roller mechanism 2 and the zoned pressure mechanism 3 will press the cotton blank. Subsequently, the cotton blank will be discharged from the other side of the box 1. During the discharge process, the thickness measurement and correction mechanism 5 will detect the thickness of the pressed cotton blank.

[0026] Specifically, the adaptive pressure roller mechanism 2 includes a pre-pressing component 201, a fine pressing component 202, and a shaping component 203. The fine pressing component 202 is located between the pre-pressing component 201 and the shaping component 203. The pre-pressing component 201 includes a fixed steel roller 2011, and a lower pressing steel roller 2012 is arranged above the fixed steel roller 2011. The interior of the housing 1 is symmetrically provided with side wall vertical grooves 2013, and a lower pressing protrusion 2014 is slidably connected inside the side wall vertical grooves 2013. The lower pressing steel roller 2012 and the lower pressing protrusion 2014 rotate. The dynamic connection includes a pre-compression assembly 201 for initial compaction of the cotton blank, a lower pressure steel roller 2012 that can move up and down along the side wall vertical groove 2013 to accommodate materials with different initial thicknesses, a hydraulic push rod inside the side wall vertical groove 2013 to drive the lower pressure protrusion 2014 to move up and down, and a shallow toothed rubber sleeve 2015 on the outside of the lower pressure steel roller 2012 to break up cotton fiber clumps while initially compacting the material, making them more evenly distributed rather than simply flattening them. The fine compression assembly 202 includes a... A primary hydraulic rod 2021 is provided. An arc-shaped bracket 2022 is fixedly mounted at the lower end of the primary hydraulic rod 2021. Several planetary pressure rollers 2023 are movably mounted on the arc-shaped bracket 2022. An adjustment groove 2024 is provided on the side wall of the arc-shaped bracket 2022. A fine-tuning slider is slidably connected inside the adjustment groove 2024. The fine-tuning slider is rotatably connected to the end of the planetary pressure rollers 2023. A secondary hydraulic rod 2025 is provided inside the adjustment groove 2024. The secondary hydraulic rod 2025 is used to drive the fine-tuning slider along the adjustment groove 2024. The groove 2024 moves to adjust the local pressing amount. The shaping component 203 includes a lower cooling roller 2031 and an upper cooling roller 2032. Both the lower cooling roller 2031 and the upper cooling roller 2032 have liquid storage cavities inside. The box body 1 is provided with a liquid filling pipe 2033, which is connected to the liquid storage cavity. During the cotton blank pressing process, cooling water can circulate into the liquid storage cavity through the liquid filling pipe 2033, thereby ensuring that the surfaces of the lower cooling roller 2031 and the upper cooling roller 2032 are in a low temperature state.

[0027] As can be seen from the above, the pre-pressing component 201, the fine pressing component 202, and the shaping component 203 are arranged sequentially along the cotton blank traveling direction. During the pressing process, the rolled pre-made cotton blank will enter the box 1 from the feeding side of the box 1 under the action of the external winding device.

[0028] Next, the cotton blank will first enter the roll gap between the fixed steel roller 2011 and the pressing steel roller 2012, thereby completing the initial coarse pressing of the cotton blank. During this process, the shallow toothed rubber sleeve 2015 on the outside of the pressing steel roller 2012 will use its surface texture to break up and redistribute the cotton fiber clumps, so that the cotton material is initially homogenized, rather than simply flattened.

[0029] Furthermore, the two ends of the pressing steel roller 2012 are installed in the vertical groove 2013 on the side wall through the pressing protrusions 2014, and can slide up and down along the groove as a whole. During the pressing operation, the workers can adjust the height of the pressing steel roller 2012 in real time according to the initial thickness of the cotton blank, so as to automatically adapt to different materials, ensure the effectiveness of the initial compaction, and avoid material jamming or insufficient pressure.

[0030] Subsequently, the first-stage hydraulic rod 2021 will drive the arc-shaped support 2022 to descend as a whole, thereby setting the reference pressing gap between the multiple planetary pressure rollers 2023 and the lower partitioned pressing mechanism 3. At this time, the cotton blank after being coarsely pressed by the pre-pressing component 201 will pass between the planetary pressure rollers 2023 and the lower partitioned pressing mechanism 3, thereby performing fine pressing processing on the cotton blank.

[0031] During the fine pressing process, the fine adjustment slider can slide along the adjustment groove 2024 under the drive of the secondary hydraulic rod 2025. Therefore, each planetary pressure roller 2023 can be independently fine-tuned in radial position. When the thickness correction mechanism 5 detects that the cotton blank is too thick or too thin, it can individually control the corresponding planetary pressure roller 2023 to press in a little more or less.

[0032] Finally, the pressed cotton blank will enter between the lower cooling roller 2031 and the upper cooling roller 2032. At the same time, circulating coolant will be pumped into the liquid storage cavity inside the two rollers through the liquid filling pipe 2033, thereby continuously removing the heat generated by pressing. During this process, the cotton blank will be further compacted and shaped, and the elastic recovery of the material can be suppressed, thereby ensuring that the final product thickness is stable and consistent.

[0033] This embodiment, by setting up an adaptive pressure roller mechanism 2, utilizes a pre-pressing component 201 for initial pressing and fiber combing, a fine pressing component 202 for high-precision forming, and a shaping component 203 for suppressing material springback. This achieves a progressive pressing process from coarse to fine, effectively ensuring uniform thickness and dense structure of the finished product, significantly improving the consistency and stability of product performance. Furthermore, this embodiment employs a two-stage adjustment mechanism using a primary hydraulic rod 2021 to control the overall gap and a secondary hydraulic rod 2025 to independently fine-tune each planetary pressure roller 2023, enabling the equipment to not only… It can set a macroscopic pressing benchmark and perform dynamic and independent compensation pressing for thickness deviations in different areas of the cotton blank, thereby achieving precise control of the finished product thickness and solving the technical bottleneck of uneven thickness in traditional equipment. In addition, by setting an adaptive pressure roller mechanism 2, the shaping component 203 can quickly cool and compact the cotton blank immediately after pressing, which can quickly eliminate the internal stress and elastic recovery tendency of the material caused by frictional heat, prevent the finished product from deforming and changing thickness during subsequent processing or storage, and fundamentally ensure the dimensional accuracy and long-term stability of the final product.

[0034] Example 2 To maximize the response speed and homogenization effect of thickness compensation and achieve efficient local compaction, based on Example 1, as follows: Figure 3 , Figure 4 , Figure 8 as well as Figure 9 As shown, this embodiment includes a zoned pressurization mechanism 3. Specifically, the zoned pressurization mechanism 3 includes symmetrically arranged mounting frames 301. An alloy steel shaft 302 is movably mounted on the mounting frame 301. A pressure chamber 303 is fixedly mounted on the outside of the alloy steel shaft 302. An internal oil passage 307 is coaxially formed inside the alloy steel shaft 302, and the internal oil passage 307 communicates with the pressure chamber 303. A hydraulic oil circuit 306 is provided on one of the mounting frames 301, and a rotary connector is provided between the hydraulic oil circuit 306 and the internal oil passage 307. A drive motor is fixedly mounted on the other mounting frame 301. The drive motor is used to rotate the alloy steel shaft 302 at a constant speed. During the rotation of the alloy steel shaft 302, the hydraulic oil circuit 306 can still input hydraulic oil into the inner oil passage 307 of the roller. The piston assembly 305 is movably installed inside the pressure chamber 303. One end of the piston assembly 305 is slidably sealed to the pressure chamber 303, and the other end of the piston assembly 305 is fixedly installed with a wear-resistant bushing 304. The wear-resistant bushing 304 is made of high elasticity, high wear resistance, and high temperature resistance polyurethane or engineering ceramic composite material. Multiple wear-resistant bushings 304 are tightly spliced ​​to form a complete and smooth cylindrical working surface.

[0035] As can be seen from the above, during precision pressing, the alloy steel shaft 302 will rotate at a constant speed under the action of the drive motor. When the alloy steel shaft 302 rotates, multiple wear-resistant bushings 304 will rotate synchronously. This rotational motion not only provides auxiliary traction for the cotton blank to move forward, but more importantly, the rotating wear-resistant bushings 304 will form continuous frictional contact with the cotton blank, which can ensure that the material enters the precision pressing area smoothly.

[0036] Next, the arc-shaped support 2022 will move downward under the action of the first-stage hydraulic rod 2021. At this time, the planetary pressure rollers 2023 in the precision pressing assembly 202 will be arc-shaped and distributed above the partitioned pressurizing mechanism 3. Together, they form an intelligent pressing station with upper and lower clamping.

[0037] Subsequently, the high-pressure oil generated by the hydraulic system is introduced into the roller oil passage 307 without leakage through the rotary connector. Next, the roller oil passage 307 will accurately deliver the hydraulic oil to multiple independent pressure chambers 303. After the hydraulic oil enters the pressure chamber 303, it will push the piston assembly 305 to move outward, thereby causing the wear-resistant bushing 304 fixed at the end of the piston assembly 305 to produce radial displacement.

[0038] At the same time, the thickness correction mechanism 5 will scan the thickness distribution of the discharged cotton blank in real time and feed the data back to the central controller. The controller will independently and dynamically adjust the oil inlet pressure of each pressure chamber 303 according to the difference between the preset target thickness and the measured data. If a section of cotton blank is detected to be too thick, the oil pressure of the pressure chamber 303 will be increased to push the wear-resistant bushing 304 to bulge outward slightly. If the thickness of a certain area is appropriate or too thin, the oil pressure will be maintained or reduced to make the wear-resistant bushing 304 retract appropriately to avoid overpressure.

[0039] This embodiment, by setting up a partitioned pressurization mechanism 3, can precisely coordinate with the planetary pressure roller 2023 of the upper precision pressing component 202 to form an intelligent clamping action of upper pressure and lower push. When the output cotton blank is detected to be too thick, the upper and lower pressures are increased synchronously to achieve efficient local compaction, which greatly improves the response speed and homogenization effect of thickness compensation. Moreover, by setting up a partitioned pressurization mechanism 3, the pressure chamber 303 is integrated into the pressure roller, and dynamic sealing oil supply is achieved through a rotary joint. This ensures that the equipment can still perform precise pressure partitioning control during continuous operation. Furthermore, the outer high-elasticity wear-resistant bushing 304 can convert the discrete piston thrust into a continuous and smooth radial pressure distribution, which can avoid damage to the surface of the cotton blank caused by sudden pressure changes.

[0040] Example 3 To ensure the material entering the main pressing zone is flat and has uniform stress, laying the foundation for subsequent high-precision pressing, based on the above embodiments, such as... Figure 1 , Figure 3 , Figure 10 as well as Figure 11 As shown, this embodiment includes a cotton guiding mechanism 4. Specifically, the cotton guiding mechanism 4 includes a lightweight frame 401 fixedly installed on the feeding side of the housing 1. Floating grooves 403 are symmetrically opened on the lightweight frame 401. A wedge-shaped guide block 402 is slidably connected to the lightweight frame 401. Fixed protrusions 404 are symmetrically arranged on both sides of the wedge-shaped guide block 402. The fixed protrusions 404 are slidably connected to the floating grooves 403. Initially, the wedge-shaped guide block 402 will be located at the lower end of the floating grooves 403 under the action of gravity. The bottom surface of the wedge-shaped guide block 402 is a bidirectional inclined wedge surface. From the feeding direction, the bottom surface is an inclined uphill surface, used to guide the cotton blank into the pressure roller biting area. From the middle to both sides, the bottom surface is a slightly convex arc surface that is high in the middle and low on both sides, which can generate a continuous, gentle stretching force on the cotton blank to both sides.

[0041] As can be seen from the above, when the mechanism is working, the rolled cotton blank will first enter the guide area under the action of external traction force. At this time, the wedge-shaped guide block 402 will naturally droop under its own weight, so that its unique bidirectional inclined wedge-shaped bottom surface will gently rest on the surface of the moving cotton blank.

[0042] This floating installation method allows the wedge guide block 402 to adapt to slight changes in the initial thickness of the cotton blank. When the cotton blank is locally thicker, the wedge guide block 402 will be slightly lifted up. When the cotton blank is thinner, the wedge guide block 402 will fall naturally under the action of gravity, always maintaining a gentle contact with the surface of the cotton blank, which can both guide and avoid excessive pressure.

[0043] Moreover, from the perspective of the feeding direction, the bottom surface is designed as an inclined upward slope. This inclined structure can smoothly guide the horizontally conveyed cotton blanks upward gradually, so that they can be fed into the roller gap inlet of the pre-compression component 201 at a better angle, which can effectively reduce the risk of jamming.

[0044] In addition, viewed from the middle to both sides, the bottom surface is a slightly convex arc-shaped surface that is high in the middle and low on both sides. When a cotton blank with slight wrinkles or a loose central arch passes through, this arc-shaped surface will generate a continuous and uniform stretching force on the cotton blank to both sides. Specifically, the middle area of ​​the cotton blank is subjected to a component force to both sides due to contact with the higher arc surface. This mechanical action can effectively unfold slight lateral wrinkles and flatten any loose material in the center to both sides, while suppressing the tendency of the edges to curl. The whole process is achieved entirely by the interaction between the kinetic energy of the cotton blank moving forward and the geometry of the guide block, thus achieving passive active flattening.

[0045] This embodiment, by setting up a cotton material guiding mechanism 4, utilizes the cooperation between the wedge-shaped guide block 402 and the floating groove 403 to intelligently pre-process the cotton blank without external power. This can optimize the feeding angle to avoid jamming, and automatically eliminate slight wrinkles and edge curling of the cotton blank through the stretching force to both sides. This ensures that the material entering the main pressing zone is flat and has uniform stress from the source, laying an ideal foundation for subsequent high-precision pressing.

[0046] Example 4 To further improve the level of intelligent manufacturing and product qualification rate, based on the above embodiments, such as Figure 1 , Figure 2 as well as Figure 12 As shown, this embodiment includes a thickness correction mechanism 5. Specifically, the thickness correction mechanism 5 includes a detection platform 501 fixedly installed on the outlet side of the housing 1. A mounting groove 502 is provided on the outer side of the housing 1. A ball screw 503 is movably installed inside the mounting groove 502. A reciprocating slider 504 is threadedly connected to the outer side of the ball screw 503. The pressed cotton blank will pass through the upper end of the detection platform 501. During this process, the reciprocating slider 504 will move back and forth under the drive of the ball screw 503. A scanning beam 505 is fixedly installed on the reciprocating slider 504. A thickness sensor 506 is provided on the scanning beam 505. During the back and forth movement of the scanning beam 505, the thickness sensor 506 will automatically measure the thickness of the cotton blank.

[0047] As can be seen from the above, the cotton blank that has completed the pressing and shaping process will be horizontally drawn out from the outlet of the box 1 and pass smoothly over the detection platform 501. At this time, the ball screw 503 installed on the outside of the box 1 will rotate in the mounting groove 502 under the drive of the servo motor, thereby driving the reciprocating slider 504 that is threaded to it to perform a uniform and smooth reciprocating scanning motion along the width direction of the cotton blank.

[0048] Meanwhile, the thickness sensor 506 (usually a non-contact laser displacement sensor or ultrasonic thickness gauge) continuously and intensively measures the thickness of the passing cotton blank at a constant sampling frequency. The collected thickness data is then transmitted to the central control system in real time, and the control system processes and analyzes the data quickly.

[0049] Once a thickness deviation in a certain area or an abnormal overall thickness trend is detected, the system will immediately generate correction instructions. These instructions will be sent to the fine pressing component 202 and the partitioned pressing mechanism 3 of the adaptive pressure roller mechanism 2 through the control network, thereby dynamically fine-tuning the production parameters and realizing real-time compensation and correction of thickness deviation.

[0050] This embodiment sets up a thickness correction mechanism 5, which uses a high-precision ball screw 503 to drive the thickness sensor 506 to perform full-width reciprocating scanning. This enables online and real-time measurement of the finished product thickness. Furthermore, the collected data is immediately fed back to the control system, driving the adaptive pressure roller mechanism 2 and the zoned pressure mechanism 3 to make dynamic adjustments. This transforms the traditional post-inspection into precise process control, greatly improving the level of intelligent production and the product qualification rate.

[0051] The control method of this invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.
