Description

Technical Field

[0001] This invention relates to the field of deep processing technology for metal sheets, and in particular to a multi-layer texture embossing device and process for metal sheets. Background Technology

[0002] Existing metal plate multi-layer texture embossing devices mainly consist of a frame, an upper embossing roller assembly, a lower embossing roller assembly, a drive transmission mechanism, and an embossing gap adjustment mechanism. The lower embossing roller is rotatably mounted on a fixed support base of the frame, while the upper embossing roller is rotatably mounted on a liftable support base of the frame. To avoid mechanical interference between the roller rotation drive mechanism and the lifting mechanism during embossing gap adjustment, existing devices generally adopt a technical solution where the upper and lower embossing rollers are independently equipped with drive motors. Specifically, the lower embossing roller is directly driven by a first motor fixedly mounted on the frame, and the upper embossing roller is directly driven by a second motor that moves synchronously with the liftable support base. During operation, the metal plate to be processed is conveyed to the embossing gap between the upper and lower embossing rollers via a guide mechanism. The control system synchronously controls the two motors to rotate in opposite directions at the same speed, driving the upper and lower embossing rollers to continuously roll-press the metal plate. When it is necessary to replace the embossing rollers with different texture specifications, the bearing seats, couplings, end covers, and related fasteners at both ends of the embossing roller must be disassembled in sequence. The old embossing roller is then axially pulled out from the shaft before the new embossing roller is installed. Finally, all connecting parts are reassembled and coaxiality is adjusted. The embossing gap is adjusted by moving the liftable support up and down using a screw and nut mechanism or a hydraulic cylinder.

[0003] However, existing multi-layer texture embossing equipment for metal sheets still faces the following pressing technical problems in practical industrial applications: Firstly, the process of replacing the embossing roller is cumbersome and complex, resulting in low production conversion efficiency. The existing embossing roller uses a fixed bearing support structure at both ends. Replacing the embossing roller requires disassembling a large number of mechanical connecting parts. The cycle of a single embossing roller replacement and debugging usually exceeds 1.5 hours, which seriously restricts the improvement of production efficiency. In particular, it cannot meet the current market demand for flexible production with small batches, multiple varieties, and rapid production changeover. Moreover, frequent disassembly and assembly operations can easily lead to a decrease in the fitting accuracy between the bearing seat and the rotating shaft, which in turn causes problems such as uneven embossing texture and increased equipment vibration, thus shortening the service life of the equipment.

[0004] Secondly, the dual-motor independent drive synchronous control has low precision, poor transmission stability, and high equipment cost and operating energy consumption. The dual-motor independent drive scheme adopted by the existing equipment to solve the problem of embossing gap adjustment and transmission interference, although avoiding mechanical interference, introduces new technical defects: the upper roller drive motor moves up and down frequently with the liftable support, and the power supply cable and signal cable of the motor are prone to fatigue breakage, poor contact and other faults, resulting in high equipment maintenance costs and high failure rate; in addition, the overall energy consumption of the dual-motor drive mode is 20% to 30% higher than that of the single-motor drive, which increases the production and operation costs of enterprises.

[0005] Therefore, it is necessary to provide a new multi-layer texture embossing device and process for metal plates to solve the above-mentioned technical problems. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the present invention provides a metal plate multi-layer texture embossing processing device and process.

[0007] The metal plate multi-layer texture embossing processing device provided by the present invention includes a base, a sliding seat at one end of the base, a fixed seat fixedly connected to the upper surface of the base, a first lifting seat above the fixed seat, and a second lifting seat above the sliding seat; a lower rotating rod and a lower guide roller are rotatably connected to the side of the fixed seat near the sliding seat, and an upper rotating rod and an upper guide roller are rotatably connected to the side wall of the first lifting seat facing the second lifting seat; two rotating cylinders are rotatably connected to the sides of the sliding seat and the second lifting seat near the fixed seat, respectively, and the ends of the lower rotating rod, the lower guide roller, the upper rotating rod, and the upper guide roller facing the sliding seat are rotatably inserted into the corresponding rotating cylinders; an upper pattern roller is fixedly sleeved on the outer wall of the upper rotating rod, and a lower pattern roller is fixedly sleeved on the outer wall of the lower rotating rod; a horizontal adjustment component is provided inside the base for driving the sliding seat to slide horizontally; vertical adjustment components are provided inside the sliding seat and the fixed seat for driving the first lifting seat and the second lifting seat to rise and fall vertically; a driving component is provided inside the fixed seat for driving the lower rotating rod and the upper rotating rod to rotate in opposite directions.

[0008] Preferably, the horizontal adjustment assembly includes a horizontal electric push rod, which is fixedly disposed inside the base in the horizontal direction, and the output end of the horizontal electric push rod is fixedly connected to the sliding seat; two horizontal guide rods are symmetrically slidably connected inside the base in the horizontal direction, and the end of the horizontal guide rod near the sliding seat is fixedly connected to the sliding seat.

[0009] Preferably, the vertical adjustment assembly includes vertical electric push rods. Both the fixed seat and the sliding seat have vertical electric push rods fixedly connected inside in the vertical direction. The output ends of the two vertical electric push rods are fixedly connected to the lower surfaces of the corresponding first lifting seat and second lifting seat, respectively. Both the fixed seat and the sliding seat have two vertical guide rods symmetrically slidably connected inside in the vertical direction. The top ends of the vertical guide rods are fixedly connected to the lower surfaces of the corresponding first lifting seat and second lifting seat, respectively.

[0010] Preferably, the drive assembly includes a drive sprocket, which is rotatably disposed inside the fixed seat and is fixedly connected to one end of the lower rotating rod; a driven sprocket is rotatably connected inside the first lifting seat; a tension sprocket is disposed inside the fixed seat; and the drive sprocket, driven sprocket, and tension sprocket are connected by the same chain drive.

[0011] Preferably, the drive assembly further includes a drive gear, and the driven sprocket facing the lower roller is fixedly connected to the drive gear via a shaft; the first lifting seat is rotatably connected to a driven gear, which is fixedly connected to one end of the upper rotating rod; the drive gear meshes with the driven gear.

[0012] Preferably, the fixed base has two slide rails symmetrically fixedly connected in the horizontal direction inside, with the two slide rails respectively facing the two sides of the tension sprocket; each of the two slide rails has a groove on its facing sidewall, and a slider is slidably connected inside the groove; the two ends of the tension sprocket are rotatably connected to the corresponding slider through a shaft.

[0013] Preferably, each slide rail is equipped with a spring inside. The end of the spring facing the tension sprocket is fixedly connected to the corresponding slider, and the end of the spring away from the tension sprocket is fixedly connected to the inner wall of the slide rail. When the spring is in a stretched state, it always has an elastic force that pulls the slider away from the drive sprocket.

[0014] Preferably, both the slider and the groove have a T-shaped longitudinal section.

[0015] Preferably, the middle sections of both the lower and upper rotating rods are regular hexagonal cylindrical segments, and both ends of both the lower and upper rotating rods are circular cylindrical segments; the longitudinal section of the circular cylindrical segment is the inscribed circle of the longitudinal section of the regular hexagonal cylindrical segment; the lengths of both the lower and upper patterned rollers are equal to the lengths of the regular hexagonal cylindrical segments, and the middle sections of both the lower and upper patterned rollers are provided with regular hexagonal through holes along their circumference that are adapted to the regular hexagonal cylindrical segments; a motor is fixedly connected to the top of the end of the base away from the sliding seat, and the output end of the motor is fixedly connected to one end of the lower rotating rod through a coupling.

[0016] The metal plate multi-layer texture embossing process provided by the present invention, using the above-mentioned metal plate multi-layer texture embossing device, includes the following steps: S1. Installation and positioning of the pattern roller: The sliding seat is driven to slide horizontally away from the fixed seat by the horizontal adjustment component, so that the lower rotating rod, lower guide roller, upper rotating rod and upper guide roller are completely separated from the corresponding rotating drum. The lower pattern roller and upper pattern roller with the target texture are coaxially sleeved on the regular hexagonal column segments of the lower rotating rod and upper rotating rod respectively. Then, the sliding seat is driven to reset by the horizontal adjustment component, so that each rotating rod and guide roller are re-inserted into the corresponding rotating drum, thus completing the axial and circumferential dual positioning of the pattern roller. S2. Embossing gap adjustment: The first and second lifting seats are driven to rise and fall vertically in sync through the vertical adjustment component, adjusting the embossing gap between the upper and lower embossing rollers to a preset value. At the same time, the guide gap between the upper and lower guide rollers is simultaneously adjusted to match the embossing gap. S3. Sheet metal passing guide: Pass the front end of the metal sheet to be processed through the guide gap between the lower guide roller and the upper guide roller in sequence, and then pull it to the embossing gap entrance between the upper embossing roller and the lower embossing roller; S4. Continuous embossing process: Start the drive assembly to drive the lower rotating rod and the upper rotating rod to rotate synchronously in opposite directions, which in turn drives the upper and lower embossing rollers to rotate in opposite directions at the same linear speed, and perform continuous roll pressing multi-layer texture embossing on the metal plate. S5. Finished Product Export and Collection: After the embossing is completed, the metal plate is exported through the rear end of the upper and lower guide rollers, completing the entire multi-layer texture embossing process.

[0017] Compared with related technologies, the metal plate multi-layer texture embossing device and process provided by the present invention have the following beneficial effects: 1. Significantly improves the efficiency of changing patterned rollers and reduces production changeover costs. This invention employs a single-end cantilevered roller support structure and a sliding seat opening and closing design, allowing for roller replacement without disassembling any bearing seats, couplings, end covers, or other mechanical connecting parts. After the sliding seat is opened via a horizontal adjustment component, the upper and lower rollers can be directly pulled out and installed along the axial direction of the rotating rod. Once the sliding seat returns to its original position, the rotating drum automatically completes the axial positioning of the roller. Combined with the circumferential positioning of the regular hexagonal column segment, the cycle for a single roller replacement and adjustment can be shortened from over 1.5 hours in existing technologies to less than 15 minutes. This design significantly reduces the labor intensity of workers, minimizes the damage to equipment precision caused by frequent disassembly and assembly operations, effectively extends the service life of the equipment, and better adapts to the current market demand for flexible production with small batches, multiple varieties, and rapid changeover.

[0018] 2. Achieve highly reliable mechanical synchronous transmission, reducing equipment costs and operating energy consumption. This invention abandons the dual-motor independent drive scheme used in existing technologies to avoid transmission interference, and instead uses a single motor in conjunction with a sprocket-gear composite transmission system to achieve synchronous counter-rotation of the upper and lower rollers. This mechanical hard synchronization method is unaffected by electromagnetic interference, load fluctuations, and other factors, and does not suffer from the synchronization error accumulation problem of dual-motor drives, thus maintaining stable transmission synchronization accuracy over a long period. Furthermore, this invention eliminates the need for complex servo control systems and high-precision encoders, significantly reducing equipment manufacturing costs; the absence of a follow-up drive motor on the upper roller side avoids fatigue breakage and poor contact in moving power and signal cables, resulting in a significant reduction in equipment failure rate and maintenance costs; compared to dual-motor drive schemes, overall operating energy consumption can be reduced by 20%–30%, effectively reducing enterprise production and operating costs.

[0019] 3. Achieve synchronous and precise adjustment of embossing gap and guide gap to improve the stability of sheet material conveying. This invention utilizes a synchronous lifting design of the first and second lifting seats to enable the upper rotating rod, upper guide roller, and corresponding two rotating drums to move vertically in sync. During the adjustment of the embossing gap between the upper and lower embossing rollers, the guide gap between the upper and lower guide rollers changes synchronously, always maintaining the same value as the embossing gap. This design ensures that the metal sheet remains straight throughout the conveying and embossing process, effectively reducing warping, wrinkles, and lateral shift of the sheet material. It avoids quality defects such as uneven embossing texture and pattern deformation, significantly improving product yield and consistency.

[0020] 4. Enables dynamic automatic compensation of chain tension, improving the stability and service life of the transmission system. This invention employs a spring-driven automatic tensioning sprocket structure. When the first lifting seat moves up and down to adjust the embossing gap, the stretched spring pulls the slider to slide automatically along the groove, causing the tensioning sprocket to adjust its position in real time. This automatically compensates for changes in the effective transmission length of the chain, ensuring the chain remains at a suitable tension. This design effectively reduces chain skipping and slippage, lowers the wear rate of the sprocket and chain, and significantly extends the service life of the transmission components. Simultaneously, it eliminates the need for manual tension adjustment, ensuring continuous production and maintaining the synchronous rotation accuracy of the upper and lower embossing rollers throughout the entire embossing gap adjustment range, thus stabilizing the embossing quality.

[0021] 5. Enables precise step-by-step adjustment of multi-layer texture phase, improving product processing quality and flexibility. This invention provides six circumferential positioning surfaces for the pattern roller by using a hexagonal column segment in the middle of the rotating rod and a hexagonal through-hole in the middle of the pattern roller. This enables precise phase adjustment of 60° steps between the upper and lower pattern rollers. When processing different types of multi-layer textures, simply rotate the pattern roller to the corresponding angle and install it directly; no repeated disassembly or adjustment is required, making operation simple and convenient. This design can meet various processing needs such as single-layer basic textures, double-layer superimposed textures, and triple-layer interlaced textures. It effectively improves the alignment accuracy of multi-layer textures, reduces quality problems such as texture misalignment, uneven overlap, and pattern distortion, and significantly enhances the decorative effect and market competitiveness of the product.

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the invention and are not intended to limit the invention.

[0025] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0026] like Figures 1 to 8 As shown, a multi-layer texture embossing device for metal plates includes a base 1, which is a rectangular box-shaped structure made of cast iron, possessing sufficient structural rigidity and stability. A sliding seat 2 is provided at one end of the base 1, with its bottom slidably connected to the upper surface of the base 1. A fixed seat 3 is fixedly connected to the upper surface of the base 1, and the fixed seat 3 is positioned opposite to the sliding seat 2. A first lifting seat 4 is provided above the fixed seat 3, and a second lifting seat 5 is provided above the sliding seat 2. The first lifting seat 4 and the second lifting seat 5 have the same structural dimensions and are located at the same horizontal height.

[0027] The fixed seat 3 is rotatably connected to the side wall of the sliding seat 2 by a lower rotating rod 6 and a lower guide roller 7. The axes of the lower rotating rod 6 and the lower guide roller 7 are parallel to each other and are both arranged in the horizontal direction. The lower guide roller 7 is located behind the lower rotating rod 6. The first lifting seat 4 is rotatably connected to the side wall of the second lifting seat 5 by an upper rotating rod 8 and an upper guide roller 9. The upper rotating rod 8 is located directly above the lower rotating rod 6, and the upper guide roller 9 is located directly above the lower guide roller 7. The axes of the upper rotating rod 8 and the lower rotating rod 6 are located in the same vertical plane, and the axes of the upper guide roller 9 and the lower guide roller 7 are also located in the same vertical plane.

[0028] like Figure 1 , Figure 3 and 8 As shown, two rotating cylinders 10 are rotatably connected to the side of the sliding seat 2 and the second lifting seat 5 near the fixed seat 3, respectively. The axes of the four rotating cylinders 10 correspond one-to-one with the axes of the lower rotating rod 6, the lower guide roller 7, the upper rotating rod 8, and the upper guide roller 9. The ends of the lower rotating rod 6, the lower guide roller 7, the upper rotating rod 8, and the upper guide roller 9 facing the sliding seat 2 are rotatably inserted into the corresponding rotating cylinders 10. The inner diameter of the rotating cylinder 10 is adapted to the outer diameter of the circular cylindrical section 27 at the end of the rotating rod and the guide roller, ensuring that the rotating rod and the guide roller can rotate freely within the rotating cylinder 10. The length of the rotating cylinder 10 is greater than the length of the circular cylindrical section 27 at the end of the rotating rod and the guide roller. When the sliding seat 2 is reset, the end face of the rotating cylinder 10 near the fixed seat 3 is in close contact with the end face of the flower roller near the sliding seat 2, forming an axial limit.

[0029] An upper pattern roller 11 is fixedly sleeved on the outer wall of the upper rotating rod 8, and a lower pattern roller 12 is fixedly sleeved on the outer wall of the lower rotating rod 6. The outer surfaces of the upper and lower pattern rollers 11 and 12 are engraved with preset multi-layered texture patterns. A horizontal adjustment assembly is installed inside the base 1 to drive the sliding seat 2 to slide horizontally along the upper surface of the base 1, thus opening and closing the device. Vertical adjustment assemblies are installed inside the sliding seat 2 and the fixed base 3, respectively, to drive the first lifting seat 4 and the second lifting seat 5 to rise and fall synchronously in the vertical direction, adjusting the embossing gap and guide gap. A drive assembly is installed inside the fixed base 3 to drive the lower rotating rod 6 and the upper rotating rod 8 to rotate in opposite directions at the same linear velocity.

[0030] like Figures 1 to 3 As shown, the horizontal adjustment assembly includes a horizontal electric push rod 13, which is fixedly installed horizontally in the internal cavity of the base 1. The cylinder of the horizontal electric push rod 13 is fixedly connected to the inner wall of the base 1, and the output end of the horizontal electric push rod 13 is fixedly connected to the side wall of the sliding seat 2 near the base 1. Two horizontal guide rods 14 are symmetrically arranged horizontally inside the base 1, located on the upper and lower sides of the horizontal electric push rod 13, respectively. The horizontal guide rods 14 are slidably connected to the base 1, and the end of the horizontal guide rod 14 near the sliding seat 2 is fixedly connected to the side wall of the sliding seat 2. When the horizontal electric push rod 13 extends or retracts, it drives the sliding seat 2 to slide smoothly along the axis of the horizontal guide rod 14. The horizontal guide rod 14 plays a guiding and supporting role, preventing the sliding seat 2 from tilting or shaking.

[0031] like Figure 4 , Figure 6 and Figure 7 As shown, the vertical adjustment assembly includes a vertical electric push rod 15. Both the fixed base 3 and the sliding base 2 have vertical electric push rods 15 fixedly connected to each other in the vertical direction. The specifications of the two vertical electric push rods 15 are identical. The output end of the vertical electric push rod 15 located inside the fixed base 3 is fixedly connected to the lower surface of the first lifting seat 4, and the output end of the vertical electric push rod 15 located inside the sliding base 2 is fixedly connected to the lower surface of the second lifting seat 5. Two vertical guide rods 16 are symmetrically arranged in the vertical direction inside both the fixed base 3 and the sliding base 2. The two vertical guide rods 16 are located on the left and right sides of the vertical electric push rod 15, respectively. The vertical guide rods 16 are slidably connected to the fixed base 3 and the sliding base 2, respectively, and their top ends are fixedly connected to the lower surfaces of the corresponding first lifting seat 4 and second lifting seat 5. The two vertical electric push rods 15 are synchronously controlled by the same control system to ensure that the first lifting seat 4 and the second lifting seat 5 can be raised and lowered synchronously, and to ensure that the free ends of the upper rotating rod 8 and the upper guide roller 9 always maintain coaxial rotation with the corresponding rotating drum 10.

[0032] like Figures 4 to 6As shown, the drive assembly includes a drive sprocket 17, which is rotatably mounted in the internal cavity of the fixed base 3. The drive sprocket 17 is coaxially fixedly connected to the end of the lower rotating rod 6 away from the sliding seat 2. A driven sprocket 18 is rotatably connected inside the first lifting seat 4, and the axis of the driven sprocket 18 is located in the same vertical plane as the axis of the drive sprocket 17. A tension sprocket 19 is also provided inside the fixed base 3, located on one side between the drive sprocket 17 and the driven sprocket 18. The drive sprocket 17, the driven sprocket 18, and the tension sprocket 19 are connected by the same chain drive, forming a closed transmission circuit.

[0033] The drive assembly also includes a drive gear 20. The driven sprocket 18 facing the lower roller 12 is coaxially and fixedly connected to the drive gear 20 via a connecting shaft, which is rotatably connected to the first lifting seat 4. The first lifting seat 4 is rotatably connected to a driven gear 21, which is coaxially and fixedly connected to the end of the upper rotating rod 8 away from the sliding seat 2. The drive gear 20 and the driven gear 21 mesh with each other, and the number of teeth of the drive gear 20 and the driven gear 21 are the same, ensuring that the rotation speed of the upper rotating rod 8 and the lower rotating rod 6 are equal in magnitude and opposite in direction.

[0034] Two slide rails 22 are symmetrically fixedly connected horizontally inside the fixed base 3. The two slide rails 22 are located on either side of the tension sprocket 19, and their length direction is parallel to the horizontal direction. Each slide rail 22 has a groove 23 on its facing sidewall, and a slider 24 is slidably connected inside the groove 23. The two ends of the tension sprocket 19's shaft are rotatably connected to the corresponding slider 24. Each slide rail 22 contains a spring 25, which is positioned along the length of the slide rail 22. The end of the spring 25 facing the tension sprocket 19 is fixedly connected to the corresponding slider 24, and the end of the spring 25 away from the tension sprocket 19 is fixedly connected to the inner wall of the slide rail 22. The spring 25 is always under tension, applying an elastic force to the slider 24 away from the drive sprocket 17, thereby causing the tension sprocket 19 to always press the chain, achieving automatic compensation of chain tension. Both the slider 24 and the groove 23 have T-shaped longitudinal sections, which can prevent the slider 24 from falling out of the groove 23 and ensure the stability of the tension sprocket 19.

[0035] like Figure 1 , Figure 3 and Figure 8As shown, both the lower rotating rod 6 and the upper rotating rod 8 have a regular hexagonal column segment 26 in the middle, and both ends of the lower rotating rod 6 and the upper rotating rod 8 have circular column segments 27. The cross-section of the circular column segment 27 is the incircle of the cross-section of the regular hexagonal column segment 26. The lengths of the lower pattern roller 12 and the upper pattern roller 11 are equal to the length of the regular hexagonal column segment 26. The middle of the lower pattern roller 12 and the upper pattern roller 11 is provided with a regular hexagonal through hole 28 that matches the regular hexagonal column segment 26. The pattern roller is sleeved on the regular hexagonal column segment 26 of the rotating rod through the regular hexagonal through hole 28 to achieve circumferential positioning, which can transmit a large torque and has high circumferential positioning accuracy. A motor 29 is fixedly connected to the top of the end of the base 1 away from the sliding seat 2. The motor 29 is a geared motor 29. The output end of the motor 29 is coaxially fixedly connected to the end of the lower rotating rod 6 away from the sliding seat 2 through a coupling.

[0036] like Figure 1 and Figure 9 As shown, the present invention also discloses a multi-layer texture embossing process for metal plates, which uses the above-mentioned multi-layer texture embossing device for metal plates and includes the following steps: S1. Installation and Positioning of the Pattern Roller: The control system extends the horizontal electric push rod 13, driving the sliding seat 2 to slide horizontally away from the fixed seat 3, so that the free ends of the lower rotating rod 6, lower guide roller 7, upper rotating rod 8, and upper guide roller 9 are completely separated from the corresponding rotating drum 10. The lower pattern roller 12 and upper pattern roller 11 with the target texture are coaxially sleeved on the regular hexagonal column segments 26 of the lower rotating rod 6 and upper rotating rod 8 through the regular hexagonal through holes 28, respectively. According to the processing requirements of multi-layer texture, the circumferential phase difference between the upper pattern roller 11 and the lower pattern roller 12 is adjusted. Then, the control system retracts the horizontal electric push rod 13, driving the sliding seat 2 to reset, so that each rotating rod and guide roller is re-inserted into the corresponding rotating drum 10, and the end face of the rotating drum 10 is tightly abutted against the end face of the pattern roller, completing the axial and circumferential dual positioning of the pattern roller.

[0037] S2. Embossing Gap Adjustment: The control system simultaneously controls the synchronous extension and retraction of two vertical electric push rods 15, driving the first lifting seat 4 and the second lifting seat 5 to rise and fall vertically synchronously, adjusting the embossing gap between the upper embossing roller 11 and the lower embossing roller 12 to a preset value. Since the upper guide roller 9 rises and falls synchronously with the upper embossing roller 11, the guide gap between the upper guide roller 9 and the lower guide roller 7 is also synchronously adjusted to the same value as the embossing gap.

[0038] S3. Plate Passing Guide: The front end of the metal plate to be processed is fed in from the rear side of the device, passes through the guide gap between the lower guide roller 7 and the upper guide roller 9 in sequence, and is then pulled forward to the embossing gap entrance between the upper embossing roller 11 and the lower embossing roller 12. The position of the metal plate is adjusted so that its edge is parallel to the edge of the embossing roller.

[0039] S4. Continuous Embossing Process: Start motor 29, which drives lower rotating rod 6 and lower embossing roller 12 to rotate via a coupling. Lower rotating rod 6 simultaneously drives drive sprocket 17 to rotate, which in turn drives driven sprocket 18 via a chain. Driven sprocket 18 drives drive gear 20 via a connecting shaft. Driven gear 20 meshes with driven gear 21, causing driven gear 21 and upper rotating rod 8 to rotate in opposite directions, thus causing upper embossing roller 11 and lower embossing roller 12 to rotate in opposite directions at the same linear velocity. The upper and lower embossing rollers 12 apply continuous roller pressure to the metal plate, causing plastic deformation of the metal plate surface and forming multi-layered decorative patterns corresponding to the surface texture of the embossing rollers. During processing, tension sprocket 19 automatically adjusts its position under the elastic tension of spring 25, always maintaining chain tension and ensuring the synchronous rotation accuracy of the upper and lower embossing rollers 12.

[0040] S5. Finished Product Export and Collection: After embossing, the metal plate is sent out from the embossing gap outlet between the upper and lower embossing rollers 12, and then exported through the rear end of the upper guide roller 9 and the lower guide roller 7. It is then collected by the subsequent winding device or conveying device to complete the entire multi-layer texture embossing process.

[0041] The working principle of the metal plate multi-layer texture embossing device provided by this invention is as follows: When the pattern roller needs to be replaced, the horizontal adjustment component drives the sliding seat 2 to slide horizontally away from the fixed seat 3, so that the free ends of the lower rotating rod 6, lower guide roller 7, upper rotating rod 8, and upper guide roller 9 are completely separated from the corresponding rotating drum 10. At this time, the upper and lower pattern rollers 12 are only fitted on the regular hexagonal column section 26 of the rotating rod and can be directly pulled out axially for replacement. After the replacement is completed, the horizontal adjustment component drives the sliding seat 2 to reset, and each rotating rod and guide roller is re-inserted into the corresponding rotating drum 10. The rotating drum 10 not only provides rotational support for the free ends of the rotating rod and guide roller, but also abuts against the end of the pattern roller near the sliding seat 2. Together with the end face limit of the regular hexagonal column section 26 of the rotating rod, it achieves axial positioning of the pattern roller and prevents the pattern roller from moving axially along the rotating rod during the embossing process.

[0042] When the embossing gap needs adjustment, the vertical adjustment component simultaneously drives the first lifting seat 4 and the second lifting seat 5 to rise and fall vertically in sync. The first lifting seat 4 drives the upper rotating rod 8 and the upper guide roller 9 to rise and fall as a whole, while the second lifting seat 5 drives the corresponding two rotating drums 10 to rise and fall synchronously, ensuring that the free ends of the upper rotating rod 8 and the upper guide roller 9 always maintain good rotational engagement with the rotating drums 10. Since the upper guide roller 9 rises and falls synchronously with the upper embossing roller 11, and the lower guide roller 7 and the lower embossing roller 12 are in fixed positions, the guide gap between the upper guide roller 9 and the lower guide roller 7 will change synchronously with the embossing gap between the upper embossing roller 11 and the lower embossing roller 12, and always maintain the same value, ensuring that the metal plate remains straight during the conveying process and avoiding warping or wrinkles.

[0043] The drive assembly adopts a single motor 29 drive scheme. The power output of motor 29 is transmitted to the lower rotating rod 6 through a coupling, driving the lower rotating rod 6 and the lower pattern roller 12 to rotate. The lower rotating rod 6 simultaneously drives the drive sprocket 17 to rotate. The drive sprocket 17 drives the driven sprocket 18 to rotate through a chain. The driven sprocket 18 drives the drive gear 20 to rotate through a shaft. The drive gear 20 meshes with the driven gear 21, driving the driven gear 21 and the upper rotating rod 8 to rotate in opposite directions, thereby achieving the opposite synchronous rotation of the upper pattern roller 11 and the lower pattern roller 12. During the process of adjusting the embossing gap by raising and lowering the first lifting seat 4, the driven sprocket 18 will move synchronously with the first lifting seat 4, causing the effective transmission length of the chain to change. At this time, the spring 25, which is in a stretched state, will pull the slider 24 to slide along the slide groove 23, driving the tension sprocket 19 to automatically adjust its position, always keeping the chain in a taut state, and ensuring that the transmission synchronization accuracy is not affected by the adjustment of the embossing gap.

[0044] The circumferential positioning between the pattern roller and the rotating rod is achieved through the cooperation of the regular hexagonal column segment 26 and the regular hexagonal through hole 28. This not only transmits sufficient torque to prevent relative rotation between the pattern roller and the rotating rod during the embossing process, but also allows for precise adjustment of the texture phase difference between the upper and lower pattern rollers 12 by rotating the pattern roller by an integer multiple of 60° and then reinstalling it, thus meeting the processing requirements of different multi-layer textures.
