Description

Technical Field

[0001] This utility model relates to the field of conductive thin film multilayer calendering technology, specifically to a multilayer composite calendering device for conductive thin film processing. Background Technology

[0002] Conductive films are composite materials that combine conductivity and high light transmittance. They are widely used in touch screens, displays, photovoltaics, transparent electromagnetic shielding, and other fields. Multilayer composite calendering equipment is a precision processing system that integrates calendering, stretching, and composite functions. Through the coordinated movement of multiple sets of rollers, metal layers are composited with polymer substrates layer by layer to form films with excellent conductivity and optical properties.

[0003] Existing conductive films do not have a cleaning function before calendering. However, the calendering surface of the conductive film (i.e. the contact surface with the metal layer and polymer substrate later) easily adsorbs suspended dust in the workshop environment during the transportation process. This suspended dust will be embedded into the composite layer during the calendering process, resulting in problems such as uneven conductivity and reduced light transmittance of the film.

[0004] For example, a PVC calendering film machine disclosed in CN222431369U includes a processing table with several calendering rollers movably connected to the upper end. A sliding groove is provided on both the front and rear sides of the lower end of the processing table. An adjustment component is provided at the lower end of the processing table, and a drive component is provided at the upper end of the adjustment component. A sponge concave plate is fixedly installed on the outer surface of the drive component. Although this patent allows the drive component to move along the sliding groove via the adjustment component, thus enabling the sponge concave plate to adapt to the cleaning needs of calendering rollers at different positions and wipe residual materials on the surface of the calendering rollers with the sponge concave plate, reducing the risk of impurities from the rollers transferring to the calendering surface of the film, its cleaning-related components (such as the sponge concave plate and drive component) are fixedly installed, making disassembly and assembly inconvenient. Therefore, when the sponge concave plate absorbs a large amount of dust and its adhesion decreases, requiring replacement, disassembly and assembly are difficult, time-consuming, and labor-intensive.

[0005] Therefore, it is necessary to invent a multilayer composite calendering device for conductive thin film processing to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a multilayer composite calendering device for processing conductive thin films, which solves the problem of inconvenient disassembly and assembly of cleaning components and regular cleaning and replacement.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multilayer composite calendering device for conductive thin film processing, comprising a machine body, with supports on both sides of one end of the machine body, three guide rollers rotatably supported between the two supports, a cleaning component disposed in the middle of the upper part of the machine body corresponding to the output end of the guide rollers, the cleaning component comprising two support plates mounted on the top surface of the machine body, three adhesive rollers disposed parallel between the two support plates, the two shaft ends of the three adhesive rollers being fixed to the support plates by a limiting component, the limiting component comprising a servo motor fixed to the side wall of the machine body by a motor mount, the output end of the servo motor being connected to a bidirectional lead screw via a coupling, the two ends of the bidirectional lead screw being rotatably supported inside the machine body by bearing seats, and the threads at the two ends of the bidirectional lead screw having opposite directions, and sliding seats being threadedly fitted on the threaded sections at both ends of the bidirectional lead screw, a calendering component disposed at the other end of the upper part of the machine body corresponding to the output end of the cleaning component.

[0008] Preferably, L-shaped mounting grooves are provided at the contact positions between the two shaft ends of the adhesive roller and the support plate. The depth of the vertical section of the mounting groove is greater than the radius of the shaft end of the adhesive roller, and the width of the horizontal section is in clearance fit with the diameter of the shaft end.

[0009] Preferably, the top surface of the machine body has a slide groove extending along the direction of the bidirectional lead screw axis at the position corresponding to the slide block, and the top of the slide block slides through the slide groove and extends to the top of the machine body.

[0010] Preferably, the limiting component further includes a limiting plate installed on the top surface of the slide block, and a cylindrical limiting sleeve is provided on the side wall of the limiting plate facing the sticky roller at the position corresponding to the end of the sticky roller shaft. The inner diameter of the limiting sleeve is in transition fit with the diameter of the end of the sticky roller shaft.

[0011] Preferably, a cylindrical limiting rod is provided at the center of the limiting sleeve, and a limiting hole with clearance fit is provided at the center of the dust-adhesive roller shaft end corresponding to the position of the limiting rod.

[0012] Preferably, the calendering assembly includes a support mounted on the top surface of the machine body. A lower pressure roller is rotatably supported inside the support via a bearing seat. One end of the lower pressure roller extends to the outside of the support and is connected to a transmission assembly. The transmission assembly includes a driven gear fixed to the shaft end of the lower pressure roller, a driving gear fixed to the output end of the drive motor, and a synchronous toothed belt tensioned and sleeved on the two gears. The drive motor is fixed inside the machine body via a motor seat.

[0013] Preferably, an upper pressure roller is arranged parallel to the lower pressure roller directly above it, and the shaft end of the upper pressure roller slides through the vertical guide grooves on both sides of the support. Hydraulic cylinders are arranged on the left and right sides of the upper pressure roller respectively. The two hydraulic cylinders are connected to a PLC controller through hydraulic pipelines. The PLC controller is installed in the control box on the side wall of the machine body. The cylinder bodies of the two hydraulic cylinders are vertically fixed to the top surface of the support through flanges, and the lower end of the piston rod is connected to the top surface of the bearing seat of the upper pressure roller through a floating joint.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. This utility model uses three adhesive rollers to fully contact the surface of the conductive film. By utilizing the adhesive properties of the adhesive rollers, the dust adhering to the surface of the conductive film is removed, thereby effectively cleaning the conductive film, improving the processing quality of the conductive film, avoiding the adverse effects of dust on subsequent processing steps such as calendering, and ensuring the performance of the final product.

[0016] 2. This utility model, through the limiting component, enables the synchronous disassembly and assembly of three adhesive rollers. When it is necessary to replace the adhesive roller, simply start the servo motor to drive the bidirectional lead screw to rotate, causing the two side slides to move away from the support plate synchronously. This allows the limiting sleeve to disengage from the shaft end of the adhesive roller and the limiting rod to be pulled out of the limiting insertion hole. Then, the old adhesive roller can be quickly removed along the L-shaped mounting groove. After installing the new adhesive roller, start the servo motor in reverse. The limiting component can then complete the precise positioning and fixing, eliminating the need to disassemble and assemble each of the three adhesive rollers individually. This significantly shortens the replacement and maintenance time of the adhesive rollers and improves the efficiency of equipment operation and maintenance. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figure 1-5 The illustrated conductive thin film processing multilayer composite calendering equipment includes a machine body 1. Supports 2 are mounted on both sides of one end of the machine body 1. Three guide rollers 3 are rotatably supported between the two supports 2. A cleaning component 4 is mounted in the middle of the upper part of the machine body 1, corresponding to the output end of the guide rollers 3. The cleaning component 4 includes two support plates 401 mounted on the top surface of the machine body 1. Three adhesive rollers 402 are arranged parallel between the two support plates 401. L-shaped mounting grooves 403 are formed at the contact points between the two shaft ends of the adhesive rollers 402 and the support plates 401. The vertical section of the mounting groove 403 has a depth greater than the radius of the shaft end of the adhesive roller 402, and the horizontal section has a width that is clearance-fitted with the shaft end diameter. The two shaft ends of the three adhesive rollers 402 are fixed to the support plates 401 by limiting components 5.

[0026] In this embodiment, when the conductive film is conveyed to the cleaning component 4 by the guide roller 3, the three adhesive rollers 402 can fully contact the surface of the conductive film. Utilizing the adhesive properties of the adhesive rollers 402, the dust adhering to the surface of the conductive film is removed, effectively cleaning the conductive film, improving the processing quality of the conductive film, avoiding adverse effects of dust on subsequent processing steps such as calendering, and ensuring the performance of the final product. Furthermore, the design of the L-shaped mounting groove 403, with its vertical section depth greater than the radius of the shaft end of the adhesive roller 402, can provide initial positioning and support for the shaft end of the adhesive roller 402, preventing large displacement of the adhesive roller 402 in the vertical direction. The width of the horizontal section is clearance-fitted with the shaft end diameter, facilitating the placement of the shaft end of the adhesive roller 402 into the mounting groove 403, providing a basis for subsequent limiting and fixing operations, and also facilitating the installation and disassembly of the adhesive roller 402.

[0027] The limiting assembly 5 includes a servo motor 501 fixed to the side wall of the body 1 via a motor mount. The output end of the servo motor 501 is connected to a bidirectional lead screw 502 via a coupling. The two ends of the bidirectional lead screw 502 are rotatably supported inside the body 1 via bearing seats, and the threads at the two ends of the bidirectional lead screw 502 have opposite directions. Slide seats 503 are threadedly fitted onto the threaded sections at both ends of the bidirectional lead screw 502. A sliding groove extending along the axis of the bidirectional lead screw 502 is opened on the top surface of the body 1 at the position corresponding to the slide seat 503. The top of the slide seat 503 slides through it. The slide extends to the top of the machine body 1. The limiting assembly 5 also includes a limiting plate 504 installed on the top surface of the slide block 503. A cylindrical limiting sleeve 505 is provided on the side wall of the limiting plate 504 facing the dust-adhesive roller 402 at the position corresponding to the shaft end of the dust-adhesive roller 402. The inner diameter of the limiting sleeve 505 is transitionally fitted with the diameter of the shaft end of the dust-adhesive roller 402. A cylindrical limiting rod 506 is provided at the center of the inside of the limiting sleeve 505. A limiting insertion hole 507 with clearance fit is opened at the center of the shaft end of the dust-adhesive roller 402 corresponding to the position of the limiting rod 506.

[0028] In this embodiment, when the servo motor 501 is working, it drives the bidirectional lead screw 502 to rotate. Since the threads at both ends of the bidirectional lead screw 502 rotate in opposite directions, the two slide blocks 503 move towards or away from each other along the axis of the bidirectional lead screw 502. The slide blocks 503 drive the limiting plate 504 to move. The limiting sleeve 505 on the limiting plate 504 covers the shaft end of the sticky roller 402 to achieve initial limiting. The inner diameter of the limiting sleeve 505 is in transition fit with the diameter of the shaft end of the sticky roller 402 to ensure the accuracy and stability of the limiting. At the same time, the limiting rod 506 is inserted into the limiting insertion hole 507 at the center of the shaft end of the sticky roller 402, which further enhances the limiting effect on the sticky roller 402 and prevents the sticky roller 402 from axially moving or rotating during operation, ensuring that the sticky roller 402 can be stably installed on the support plate 401.

[0029] At the other end of the upper part of the machine body 1, corresponding to the output end of the cleaning component 4, a calendering component 6 is provided. The calendering component 6 includes a support 601 installed on the top surface of the machine body 1. Inside the support 601, a lower pressure roller 602 is rotatably supported via a bearing seat. One end of the lower pressure roller 602 extends to the outside of the support 601 and is connected to a transmission component 603. The transmission component 603 includes a driven gear fixed to the shaft end of the lower pressure roller 602, a driving gear fixed to the output end of the drive motor, and a synchronous toothed belt tensioned and sleeved on the two gears. The drive motor is fixed to the machine body via a motor seat. Inside the machine body 1, an upper pressure roller 604 is arranged parallel to the lower pressure roller 602 directly above it, and the shaft ends of the upper pressure roller 604 slide through the vertical guide grooves on both sides of the support 601. Hydraulic cylinders 605 are arranged on the left and right sides of the upper pressure roller 604 respectively. The two hydraulic cylinders 605 are connected to a PLC controller through hydraulic pipelines, and the PLC controller is installed in the control box on the side wall of the machine body 1. The cylinder bodies of the two hydraulic cylinders 605 are vertically fixed to the top surface of the support 601 through flanges, and the lower end of the piston rod is connected to the top surface of the bearing seat of the upper pressure roller 604 through a floating joint.

[0030] In this embodiment, the transmission component 603 adopts a transmission method consisting of a driven gear, a driving gear, and a synchronous toothed belt. The drive motor drives the driving gear to rotate, and the synchronous toothed belt transmits power to the driven gear, thereby driving the lower pressure roller 602 to rotate. This transmission method has the advantages of smooth transmission, accuracy, and low noise, ensuring that the lower pressure roller 602 rotates stably at the set speed, providing stable power support for the calendering of the conductive film. Furthermore, the upper pressure roller 604 slides through the vertical guide grooves on both sides of the support 601, ensuring that the upper pressure roller 604 moves linearly in the vertical direction, improving the calendering accuracy. The two hydraulic cylinders 605 are connected to the PLC controller through hydraulic pipelines. The PLC controller can precisely control the extension and retraction of the piston rod of the hydraulic cylinders 605 according to the preset program, thereby accurately adjusting the distance between the upper pressure roller 604 and the lower pressure roller 602, achieving precise control of the calendering thickness of the conductive film, meeting the processing requirements of conductive films of different specifications, and improving the standardization and quality stability of the products.

[0031] Working principle of this utility model:

[0032] Refer to the instruction manual appendix Figure 1-5When using this invention, firstly, one end of the three conductive films is passed sequentially under the guide rollers 3 between the two supports 2 at one end of the upper part of the machine body 1, so that the conductive films are conveyed to the cleaning component 4. This ensures that the conductive films are in flat contact with the surface of the adhesive rollers 402. When the conductive films pass through the cleaning component 4, the three adhesive rollers 402 make full contact with the surface of the three conductive films. Utilizing the adhesive properties of the adhesive rollers 402, the dust adhering to the surface of the conductive films is removed, effectively cleaning the conductive films and improving the subsequent calendering processing quality. Then, by operating the PLC controller in the control box on the side wall of the machine body 1, the upper pressure roller 604 and lower pressure roller 604 are preset according to the specifications and processing requirements of the conductive films. The distance between the upper roller 604 and the lower roller 602 is the calendering thickness of the conductive film. The PLC controller can precisely control the extension and retraction of the piston rod of the hydraulic cylinder 605 according to the preset program, thereby accurately adjusting the distance between the upper roller 604 and the lower roller 602. The drive motor is started by the control device, and the drive motor drives the drive gear to rotate. The drive gear transmits power to the driven gear through the synchronous tooth belt, which in turn drives the lower roller 602 to rotate. As the lower roller 602 rotates, the cleaned conductive film is transported from the output end of the cleaning component 4 to the calendering component 6 and enters between the upper roller 604 and the lower roller 602. Under the joint action of the upper roller 604 and the lower roller 602, the conductive film is subjected to pressure and undergoes plastic deformation, realizing the calendering process.

[0033] When the adhesive roller 402 needs to be cleaned periodically, the servo motor 501 is started by the control device. The servo motor 501 drives the bidirectional lead screw 502 to rotate. The two slides 503 move towards each other along the axis of the bidirectional lead screw 502. The slides 503 drive the limit plate 504 to move, so that the limit sleeve 505 on the limit plate 504 moves away from the shaft end of the adhesive roller 402. At the same time, the limit rod 506 disengages from the limit insertion hole 507 at the center of the shaft end of the adhesive roller 402. Finally, the shaft end of the adhesive roller 402 is directly removed from the horizontal section of the L-shaped mounting groove 403 on the support plate 401. The disassembly is completed when the shaft end is removed from the vertical section of the mounting groove 403. After cleaning, the adhesive roller 402 can be directly reinstalled. The operation is simple and convenient.
