[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Reference Figures 1-4 A conductive silicone rubber calendering and laminating device includes a column 1, a support plate 2 installed on the top of the column 1, an L-shaped vertical plate 3 and a protective cover 4 respectively installed on the top of the support plate 2, and the protective cover 4 is also threaded to the surface of the L-shaped vertical plate 3 by screws. A calendering thickness adjustment mechanism 5 and a two-end size positioning mechanism 6 are respectively provided between the opposite surfaces of the two L-shaped vertical plates 3.

[0015] The calendering thickness adjustment mechanism 5 enables the conductive silicone rubber to automatically adjust the calendering thickness according to the set rubber sheet thickness. The calendering thickness adjustment mechanism 5 includes a calendering conveyor roller 51, a calendering drive motor 52 installed on the top of the right support plate 2, and the bottom surfaces of the two L-shaped vertical plates 3 are respectively rotatably connected to the two ends of the calendering conveyor roller 51 through bearings. The input end of the calendering conveyor roller 51 is installed to the output end of the calendering drive motor 52 through a coupling. An auxiliary bearing seat 53 is installed on the front surface of the L-shaped vertical plate 3, and the opposite surfaces of the two auxiliary bearing seats 53 are rotatably connected to auxiliary rollers 54 through bearings.

[0016] Specifically, this is implemented in two ways: First, the calendering conveyor roller 51 is rotatably connected to the bottom end of the L-shaped vertical plate 3 via bearings. Power is transmitted via a coupling to the calendering drive motor 52, ensuring precise and efficient power transmission and smooth, uninterrupted operation. This provides stable and reliable power support for the automatic adjustment of the calendering thickness and avoids speed deviations or interruptions during power transmission, ensuring the timeliness and accuracy of calendering thickness adjustment and effectively preventing rubber sheet thickness fluctuations caused by unstable power. Second, the calendering conveyor roller 51 is symmetrically connected to the L-shaped vertical plate 3 at both ends via bearings, resulting in balanced force on the roller and high coaxiality of rotation. This prevents roller offset or tilting during calendering, thereby ensuring uniform calendering thickness of the conductive silicone rubber in the width direction and significantly reducing local thickness deviations. Firstly, it improves the dimensional accuracy of the product. Secondly, the auxiliary bearing seat 53 at the front end of the L-shaped vertical plate 3 provides a stable mounting carrier for the auxiliary roller 54. The auxiliary roller 54 is connected by a bearing rotation. On the one hand, it can pre-support and guide the conductive silicone rubber, preventing the material from sagging or shifting due to its own weight before calendering. This ensures that the material enters the calendering area of ​​the calendering conveyor roller 51 in a flat posture, laying the foundation for the accurate operation of the automatic thickness adjustment mechanism and reducing the calendering thickness error caused by material wrinkles and shifts. On the other hand, the auxiliary roller 54 can rotate synchronously with the material conveying. By replacing sliding friction with rolling friction, it reduces the friction and wear during the material conveying process, avoids scratches, damage and other defects on the surface of the conductive silicone rubber, and ensures the integrity of the product's appearance quality and conductivity.

[0017] The top of the L-shaped vertical plate 3 is provided with a drive groove 55. The inner wall of the drive groove 55 is slidably inserted with a drive slide block 56. The top of each of the two drive slide blocks 56 is equipped with a drive pressure plate 57. The opposing surfaces of the two drive slide blocks 56 are rotatably connected to a calendering roller 58 through a bearing. The conductive silicone rubber plate is located above the auxiliary roller 54 and below the calendering roller 58 and above the calendering conveyor roller 51. The top of the two L-shaped vertical plates 3 is also equipped with a top plate 59. The top of the top plate 59 is equipped with a drive cylinder 510. The two drive cylinders 510 are symmetrically arranged. The telescopic bottom ends of the two drive cylinders 510 penetrate through and extend to the bottom of the top plate 59, and are both installed on the top of the drive pressure plate 57.

[0018] Specifically, this is implemented in two ways: First, the sliding engagement of the drive slide 55 and the drive slide 56 provides precise guidance for the lifting and lowering movement of the calendering roll 58, ensuring that the calendering roll 58 remains parallel to the calendering conveyor roll 51 throughout the thickness adjustment process. This avoids localized calendering of the conductive silicone rubber that is too thin or too thick due to roll tilting, significantly improving the uniformity and dimensional accuracy of the calendering thickness, and providing structural assurance for automatically adjusting calendering parameters according to the set thickness. Second, two symmetrically arranged drive cylinders 510 serve as power sources, synchronously driving the drive slide 56 and the calendering roll via the drive pressure plate 57. The up-and-down movement of roller 58 not only enables precise control of the gap between calendering roller 58 and calendering conveyor roller 51, thus allowing for precise adjustment of the calendering thickness to meet processing requirements for different rubber sheet thicknesses, but also enables rapid switching of calendering thickness through quantifiable control of the cylinder's extension and retraction stroke. This significantly improves the device's adaptability and processing efficiency for conductive silicone rubber products of different specifications, solving the pain points of traditional manual thickness adjustment being time-consuming and inaccurate. Thirdly, the installation position of calendering roller 58 works in coordination with auxiliary roller 54 and calendering conveyor roller 51, with the conductive silicone rubber sheet being pre-supported and guided by auxiliary roller 54. Then, it smoothly enters the calendering area between the calendering roll 58 and the calendering conveyor roll 51. The calendering roll 58 applies uniform pressure under the drive of the drive cylinder 510. Combined with the conveying power of the calendering conveyor roll 51, it realizes a continuous processing flow of "pre-guiding - precise calendering - stable conveying". This not only avoids wrinkles and deviations of the material during calendering, but also ensures that the calendering force is evenly distributed in the width direction of the material, further reducing the product thickness deviation and improving the yield. Fourth, the top plate 59 provides a stable mounting carrier for the drive cylinder 510. The symmetrically arranged cylinders make the forces on both ends of the calendering roll 58 even. This effectively prevents the roller from deforming due to uneven force, extending the service life of the calendering roller 58. At the same time, the sliding connection structure between the drive slide 56 and the drive groove 55 reduces motion resistance and mechanical wear. Combined with the bearing rotation connection design, it ensures smooth operation and low noise, improving the stability and reliability of the device. Fifth, the automated drive method of the drive cylinder 510 replaces the traditional manual adjustment, which not only reduces the intensity of manual operation and human error, but also can be linked with the automatic control system to realize automatic closed-loop control of calendering thickness, meeting the needs of industrial mass production.

[0019] The two-end size positioning mechanism 6 realizes the action of positioning the thickness dimensions of the left and right ends to be the same during the adjustment of the rolling thickness adjustment mechanism 5; the two-end size positioning mechanism 6 includes a vertical guide rail 61, which is installed on the side of the L-shaped upright plate 3, and the two vertical guide rails 61 on the surface of each L-shaped upright plate 3 are symmetrically arranged. A vertical slider 62 is slidably inserted into the surface of the vertical guide rail 61, and an adjustment drive plate 63 is installed at the bottom of each of the two vertical sliders 62. A pointer 64 is installed at one end of the adjustment drive plate 63; a grating ruler 68 is also installed on the side of the L-shaped upright plate 3, and one end of the pointer 64 is installed with the sliding end of the grating ruler 68.

[0020] Specifically, the vertical guide rails 61 are symmetrically installed on the sides of the L-shaped vertical plate 3. The sliding engagement of the vertical slider 62 with the guide rails provides a stable and precise guiding constraint for the adjustment drive plate 63, ensuring that the pointer 64 maintains a synchronous displacement trajectory as it moves with the calendering roller 58. This avoids detection deviations caused by installation offsets and lays the structural foundation for accurate detection of the distance between the two ends. The cooperation between the pointer 64 and the grating ruler 68 enables real-time, high-precision detection of the distance between the two ends of the calendering roller 58 and the two ends of the bottom auxiliary roller 54, dynamically capturing the distance between the two ends during the calendering thickness adjustment process. The minute changes in the gap provide timely feedback on deviation information, providing data support for the closed-loop control of the calendering thickness adjustment mechanism 5. This fundamentally avoids the problem of uneven thickness on both sides during the calendering process of conductive silicone rubber sheets, significantly improving the thickness consistency and dimensional accuracy in the width direction of the product. This mechanism works in deep collaboration with the calendering thickness adjustment mechanism 5. When the drive cylinder 510 moves the calendering roller 58 up and down to adjust the thickness, the positioning and detection of the gap at both ends are completed simultaneously. There is no need to add an additional independent detection process, which not only ensures the continuity of calendering processing, but also simplifies the operation process and reduces the cost of manual intervention.

[0021] An upper limit plate 65 is installed on one side of the top of the vertical guide rail 61, and a lower limit plate 66 is installed on the side of the top of the vertical slider 62. A tension spring 67 is installed on the bottom of the upper limit plate 65 and the top of the lower limit plate 66.

[0022] Specifically, the upper limit plate 65 and the lower limit plate 66 form a mechanical limiting engagement, which can precisely limit the sliding stroke of the vertical slider 62 along the vertical guide rail 61. This effectively prevents the slider from over-traveling due to excessive adjustment or external impact, and prevents excessive squeezing between the calendering roller 58 and the auxiliary roller 54 from causing component deformation such as roller damage, guide rail wear, or excessive gap affecting the effectiveness of positioning detection. It defines a safe stroke range for the mechanism's operation, protecting the vertical guide rail 61, the vertical slider 62, and related calendering components, and extending the overall service life of the device. The tension spring 67 connects the upper limit plate 65 and the lower limit plate 66, providing a continuous and stable elastic restoring force. On the one hand, it ensures that the vertical slider 62 always fits against the guide surface of the vertical guide rail 61, eliminating sliding gaps and preventing pointer 6 from being affected by gaps. 4. Displacement deviation ensures the detection accuracy of pointer 64 and grating ruler 68, thereby guaranteeing the accuracy of the distance detection between the two ends of calendering roll 58 and auxiliary roll 54, providing a reliable guarantee for uniform thickness positioning at both ends; on the other hand, when the calendering thickness adjustment mechanism 5 completes thickness switching or the device stops, the tension spring 67 can drive the vertical slider 62 to quickly reset to the initial positioning position without manual intervention, improving the ease of operation and processing continuity of the mechanism, and avoiding the problem of recalibration due to slider position deviation during the next start-up; the elastic buffering effect of tension spring 67 can absorb the vibration generated during calendering, reduce the instantaneous deviation of vertical slider 62 due to vibration, ensure the stability of slider during detection and positioning, avoid detection data fluctuations caused by vibration, and further improve the consistency of dimensional positioning at both ends.

[0023] The grating ruler 68, as a high-precision displacement detection element, works in conjunction with the pointer 64 and the rigid connection between the sliding end to achieve real-time synchronous detection of the distance between the two ends of the calender roll 58 and the auxiliary roll 54. The pointer 64 moves synchronously with the vertical slider 62 and the lifting and lowering motion of the calender roll 58, driving the sliding end of the grating ruler 68 to move, ensuring that the detection data is completely consistent with the actual distance change. This avoids detection deviations caused by loose connections or relative displacement between the pointer 64 and the detection element. The detection accuracy is significantly improved compared to traditional mechanical measurement methods, accurately capturing micron-level distance fluctuations and providing core data support for the uniformity of thickness at both ends. The high-precision detection data from the grating ruler 68 can be directly fed back to the device control system for adjustment of the calender thickness. The drive cylinder 510 of mechanism 5 forms a closed-loop control: when a deviation in the distance between the two ends of the calendering roller 58 is detected, the system can quickly adjust the extension stroke of the corresponding cylinder to correct the distance deviation in real time, ensuring that the calendering roller 58 always maintains parallelism with the auxiliary roller 54, fundamentally eliminating the problem of uneven thickness on both sides during the calendering process of conductive silicone rubber sheet, and significantly improving product size consistency and yield; the grating ruler 68 has a quantitative data output function, which can intuitively display the real-time distance between the two ends of the calendering roller 58, making it convenient for operators to monitor processing parameters in real time, and at the same time facilitating the digital recording and traceability of the processing process, providing data support for product quality control, and adapting to the standardized needs of industrial mass production.

[0024] This conductive silicone rubber calendering and laminating device achieves multiple core benefits through the collaborative design of its various mechanisms: First, the overall structure relies on the column 1, support plate 2, and L-shaped upright plate 3 to construct a stable frame, while the protective cover 4 protects against impurities and interference, providing stable support for the operation of each mechanism and ensuring processing continuity; Second, the calendering thickness adjustment mechanism 5, through the collaboration of the drive cylinder 510, calendering roller 58, and calendering conveyor roller 51, combined with the precise guidance of the drive chute 55, achieves automated and precise adjustment of the calendering thickness, quickly adapting to products of different specifications and solving the pain points of low efficiency and poor accuracy of traditional manual adjustment; Third, the two-end dimension positioning mechanism 6 utilizes the grating ruler 68 The high-precision real-time detection of pointer 64, combined with the rolling adjustment mechanism, forms a closed-loop control, accurately correcting the distance deviation at both ends, eliminating uneven thickness on both sides from the root, and significantly improving product dimensional consistency and yield. Fourth, the cooperation of the upper limit plate 65, lower limit plate 66, and tension spring 67 not only protects the travel limit components from damage, but also eliminates sliding gaps and buffers vibration through elastic reset, ensuring detection accuracy and the service life of the mechanism. Fifth, the device has a high degree of automation, reducing manual intervention and errors, and the quantitative data output facilitates quality traceability, adapting to the needs of industrial mass production. At the same time, it has a compact structure, smooth operation, and combines practicality and reliability.

[0025] Working principle: Check the status of each component of the device to ensure that the supporting structures such as column 1, support plate 2, and L-shaped vertical plate 3 are stable, the calendering conveyor roller 51, auxiliary roller 54, and calendering roller 58 rotate flexibly, the vertical guide rail 61 and the slider are adequately lubricated, the tension spring 67 is not loose, and the grating ruler 68 is functioning normally; input the thickness parameter of the target conductive silicone rubber plate through the control system.

[0026] According to the input parameters, the control system commands two symmetrically arranged drive cylinders 510 to extend and retract synchronously, driving the drive pressure plate 57 and drive slide 56 to rise and fall along the drive slide groove 55, initially adjusting the initial gap between the calendering roller 58 and the calendering conveyor roller 51. At the same time, the vertical slider 62 moves in conjunction with the drive slide 56, and the pointer 64 and the sliding end of the grating ruler 68 move synchronously to complete the initial position calibration.

[0027] The conductive silicone rubber sheet to be processed is placed flat above the auxiliary roller 54. The auxiliary roller 54 pre-guides the material through rolling support to prevent the material from sagging or shifting due to its own weight, and ensures that it is aligned with the calendering area between the calendering roller 58 and the calendering conveyor roller 51 in a flat posture.

[0028] The calendering drive motor 52 is started, and the motor transmits power to the calendering conveyor roller 51 through the coupling, driving the calendering conveyor roller 51 to rotate at a uniform speed; at the same time, the drive cylinder 510 precisely adjusts the pressing height and pressure of the calendering roller 58 according to the control system command. Under the combined action of the conveying force of the calendering conveyor roller 51 and the calendering force of the calendering roller 58, the material completes the calendering process of the set thickness.

[0029] During the calendering process, the grating ruler 68 detects the distance between the two ends of the calendering roll 58 and the auxiliary roll 54 in real time and dynamically feeds the detection data back to the control system. If a deviation is detected in the distance between the two ends, the control system immediately instructs the drive cylinder 510 on the corresponding side to finely adjust the extension stroke to correct the distance deviation and ensure that the thickness of the conductive silicone rubber sheet is consistent at both ends.

[0030] The calendered conductive silicone rubber sheet is continuously conveyed to the outside of the device by the calendering conveyor roller 51, completing a single processing cycle; the calendering drive motor 52 is turned off, the drive cylinder 510 drives the calendering roller 58 to rise and reset, the tension spring 67 pulls the vertical slider 62 to reset to the initial position along the vertical guide rail 61, the control system records the processing parameters such as thickness and detection data, and the device is ready for the next batch of processing.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
