Description

Technical Field

[0001] The present invention relates to the technical field of release film compounding equipment, and particularly to a specification-adjustable release film compounding equipment and method. Background Art

[0002] A release film refers to a film with distinguishable surface energy. The release film does not have adhesiveness or has slight adhesiveness after contacting a specific material under limited conditions. Its main functions include excellent properties such as isolation, filling, protection, and easy peeling.

[0003] Polyester release film (PET release film) is a commonly used release film, and the base material is a PET film. During its preparation, it is usually necessary to apply a release agent to the base material. Currently, different release force release films need to be produced according to different requirements. When producing the existing release films, different release forces are achieved by adjusting the thickness of the release agent applied to the side surface. Currently, the method of spraying the release agent with a nozzle and scraping it with a squeegee is used, but the coating effect of this method is not good and the cost is high. In addition, there is also an operation of coating the base material with different coating rollers. When producing release films with different release forces, the coating rollers need to be replaced, resulting in poor production efficiency. Therefore, we propose a specification-adjustable release film compounding equipment and method. Summary of the Invention

Two groups of first trigger slots are provided on the side of the second group of trigger rods. Third trigger slots are provided on the sides of the first group and the third group of trigger rods. The third trigger slots are at corresponding positions to the two groups of first trigger slots.

First trigger slots are provided on the sides of the first group and the third group of trigger rods, and the first trigger slots are at positions corresponding to the second trigger slots of the second group of trigger rods;

[0008] The auxiliary component includes a fixed extrusion roller and a movable extrusion roller, and clamping plates and a guiding group are provided on its side.

[0009] Further, the coating component includes a coating roller rotatably arranged inside the frame. An inner cavity is provided inside the coating roller. A feeding group is provided on the side of the coating roller. A mounting plate is movably installed inside the inner cavity. A connecting cavity is provided on the inner wall of the inner cavity. A trigger rod is movably installed inside the connecting cavity. First trigger slots, second trigger slots, and third trigger slots are equidistantly and staggeredly provided on the side of the trigger rod. A discharge hole is provided on the top wall of the connecting cavity. A linkage rod is movably installed inside the discharge hole. A first spring is fixedly connected between the side of the linkage rod and the wall surface of the discharge hole.

[0010] Further, a mounting cavity is provided on the wall surface of the inner cavity. A second electric push rod is fixedly installed on the wall surface of the mounting cavity. The output end of the second electric push rod is fixedly installed with a motor. The output end of the motor is fixedly installed with a matching rod. Stirring rods are fixedly installed on the side of the matching rod.

[0011] Further, the auxiliary component includes a fixed extrusion roller rotatably installed inside the frame. A movable extrusion roller is rotatably installed inside the frame. A third electric push rod is fixedly installed inside the frame. A connecting rod is fixedly installed on the side of the circular ring connecting piece at the output end of the third electric push rod. A scraping plate is provided on the side of the connecting rod. A first bolt group is fixedly installed on the side of the connecting rod.

[0012] Further, a mounting block is fixedly installed inside the frame. Detection blocks penetrate through the upper and lower sides of the mounting block. A clamping plate is movably installed inside the mounting block. A constraint rod is fixedly installed inside the mounting block. A second spring is fixedly connected between the inside of the mounting block and the side of the clamping plate. Sliding grooves are provided on the sides of the clamping plate facing away from each other. The guiding group is provided on the sides of the clamping plate facing away from each other. A second bolt group is movably installed inside the sliding grooves.

[0013] A usage method of a specification-adjustable release film composite device: Before use: First step, according to the widths of the base film and the composite film, loosen the second bolt group and then adjust the position of the guiding group, and then tighten to fix the guiding group;

[0014] Second step, control the coating assembly through the control cabinet to switch to the state with the required release force for use. The second electric push rod defaults to push the motor to make the fitting rod fit against the side of the mounting plate near the feeding group. The motor drives the fitting rod to rub against the mounting plate, causing the trigger rod to slide inside the connection cavity and trigger the corresponding linkage rod. At this time, the fitting rod blocks the feeding group;

[0015] Third step, place the base film and the composite film between the clamping plates. Use the elastic force provided by the second spring to squeeze and fix the base film and the composite film. The synchronous guiding group also clamps on the side position of the release film after the base film and the composite film are laminated. Install the laminated release film on the side of the first material roll to complete the preparation for use.

[0016] Furthermore, during use: First step, use the second electric push rod to pull the motor to make the fitting rod disengage from the side of the mounting plate. Feed the external release agent into the inner cavity through the feeding group. The release agent flows into the connection cavity through the inner cavity and then discharges from the discharge hole. At the same time, the base film fits against the side of the coating roll and contacts the release agent for coating operation. The synchronous motor drives the fitting rod to rotate, and the stirring rod can stir the release agent;

[0017] Second step, clamp the composite position of the base film and the composite film through the clamping plates. The detection block detects the distance change of the clamping plates and feeds it back to the internal control module of the control cabinet. Judge the composite thickness of the base film and the composite film according to the data, and make the control module control the third electric push rod to push and pull to adjust the distance between the movable extrusion roll and the fixed extrusion roll, so that the fixed extrusion roll and the movable extrusion roll perform heating and stable lamination operation on the base film and the composite film. At the same time, the position of the movable extrusion roll is adjusted, and the connecting rod drives the scraper to adjust the distance from the base film, so that the scraper levels the thickness of the release agent to match the coating;

[0018] Third step, when switching production of release films with different release forces during production, use a tool to cut and disconnect the release film between the clamping plates and the fixed extrusion roll. At this time, the clamping plates can clamp the release film. Control the state switching of the coating assembly through the control module of the control cabinet. That is, at this time, the second electric push rod pulls the motor to make the fitting rod fit against the side position of the mounting plate far from the feeding group. The motor drives the fitting rod to rotate to adjust the position of the trigger rod inside the connection cavity. At this time, just pull the release film and install it on the side of the first material roll to start the production and use of a new release film. Production switching can be carried out without changing production, improving efficiency.

[0019] Furthermore, after use: First step, disassemble the first material roll and the second material roll, cut the corresponding release film, and remove the base film and the composite film;

[0020] In the second step, the cleaning liquid is conveyed into the inner cavity by the feeding group. At this time, the coating assembly switches to fully open the discharge holes, and the inner part of the coating roller is cleaned and rinsed with the cleaning liquid. The synchronous cooperation rod rotates and stirs between the mounting plates to enhance the cleaning effect. After completion, all components are restored to the default state and the power is cut off.

[0021] Compared with the prior art, the beneficial effects that the present invention can achieve are:

[0022] 1. By setting the coating assembly and the auxiliary assembly, when producing the release film by coating and laminating, it is not necessary to replace the coating roller to produce release films with different release force requirements. And there are fewer internal trigger driving components, and most of the trigger components are mechanical structures, so the cost is controlled. In addition, with the cooperation of the auxiliary assembly, the production of release films with different release forces can be switched at any time during the production process. The operation is convenient and semi-automatic, greatly reducing the number and duration of production changeovers, and improving the on-site production efficiency.

[0023] 2. By setting the clamping plate and its peripheral components, the clamping plate can clamp the laminated release film, and the distance between the clamping plates can be detected through the mounting block to detect the thickness of the substrate film and the composite film in real time after lamination. The third electric push rod is controlled to adjust the distance between the movable pressing roller and the fixed pressing roller, and the distance between the scraping plate and the substrate film can be adjusted, and combined with the scraping operation of the release agent on its side, to ensure the subsequent lamination effect of the release film.

[0024] 3. By setting the trigger rod and its peripheral components, the coating assembly can be adjusted in multiple states only through a set of driving ends, and the trigger component is a mechanical structure, which reduces the cost while ensuring the trigger stability.

[0025] 4. By setting the cooperation rod and its peripheral components, when the cooperation rod contacts the side of the mounting plate far from the feeding group, it can drive the trigger rod to perform the triggering operation. When the cooperation rod contacts the side of the mounting plate close to the feeding group, it can also drive the trigger rod to perform the triggering operation and can block the feeding group to prevent the release film from flowing into the inner cavity when not in use. In addition, when the cooperation rod does not contact the mounting plate, it can drive the stirring rod to rotate inside the inner cavity, stir the release film to avoid its excessive viscosity and poor flowability, and can stir the cleaning liquid later to improve the cleaning effect inside the coating roller.

[0041] Through the provided coating assembly 2, multi-state coating operations can be performed on the film to adapt to the production and use of release films with different release forces;

[0042] As Figures 2 to 8As shown, the coating assembly 2 includes a coating roller 21 rotatably arranged inside the frame 11, and one end of the coating roller 21 is connected to the drive module inside the control cabinet 1 and is driven by it to rotate. An inner cavity 22 is provided inside the coating roller 21. The inner cavity 22 is a cylindrical cavity with an I-shaped cross-section. A feeding group 211 is arranged on the side of the coating roller 21 away from the control cabinet 1, and the feeding group 211 penetrates into the inner cavity 22 and is rotatably connected to the coating roller 21. The other end of the feeding group 211 is connected to the release agent feeding device. Symmetrically movable mounting plates 221 are installed inside the inner cavity 22. The mounting plates 221 are circular ring plates. Connecting cavities 23 are equidistantly arranged in a circumferential array on the inner wall of the inner cavity 22. The connecting cavities 23 are "T"-shaped arc-shaped cavities. The number of the connecting cavities 23 is a multiple of three. Trigger rods 231 are movably installed inside the connecting cavities 23, and the trigger rods 231 are fixedly connected to the side surfaces between the mounting plates 221. The trigger rods 231 are arc-shaped rods. First trigger grooves 232, second trigger grooves 233, and third trigger grooves 234 are alternately arranged equidistantly on the side surface of the trigger rod 231. The first trigger grooves 232, second trigger grooves 233, and second trigger grooves 233 are rectangular grooves. The width ratio of the first trigger grooves 232, second trigger grooves 233, and second trigger grooves 233 is 1:2:3. Discharge holes 24 penetrating the coating roller 21 are equidistantly arranged on the top wall of the connecting cavity 23. The discharge holes 24 are cylindrical holes with an I-shaped cross-section. Link rods 241 are movably installed inside the discharge holes 24, and the link rods 241 are attached to the side surface of the trigger rod 231. The link rods 241 are cylindrical rods with an I-shaped cross-section. A first spring 242 is fixedly connected between the side surface of the link rod 241 and the wall surface of the discharge hole 24, and the first spring 242 is movably sleeved on the side surface position of the link rod 241;

[0043] Among them, as Figure 7As shown, the distribution of the first trigger groove 232, the second trigger groove 233 and the third trigger groove 234 is formed into a unit with three groups of trigger rods 231. The side of the second group of trigger rods 231 is equidistantly provided with two groups of first trigger grooves 232 corresponding to the position of the discharge hole 24. The side of the first and third groups of trigger rods 231 is equidistantly provided with third trigger grooves 234 corresponding to the discharge hole 24. The third trigger groove 234 corresponds to the position of the two groups of first trigger grooves 232. The side of the second group is equidistantly provided with second trigger grooves 233 corresponding to the position of the discharge hole 24 at staggered adjacent positions of the two groups of first trigger grooves 232. The second trigger grooves 233 correspond to the position of the discharge hole 24. The side of the first and third groups of trigger rods 231 is equidistantly provided with second trigger grooves 233 corresponding to the position of the discharge hole 24. A first triggering groove 232 is provided and the first triggering groove 232 corresponds to the position of the second triggering groove 233 of the second group of triggering rods 231; specifically, the mounting plate 221 can be driven to rotate through subsequent components, and the mounting plate 221 drives the triggering rod 231 to slide inside the connecting cavity 23 when rotating. In the default state, the triggering rod 231 is pressed on the side of the linkage rod 241 to block the discharge hole 24. According to the rotation position of the triggering rod 231, the elastic force of the first spring 242 triggers the linkage rod 241 at the corresponding position to slide into the first triggering groove 232, the second triggering groove 233 and the third triggering groove 234. At this time, the discharge holes 24 at different positions are connected to discharge the release agent for coating and use;

[0044] The inner cavity 22 is provided with an installation cavity 25 on the wall away from the feeding group 211. The installation cavity 25 is a cylindrical cavity with a convex cross-section. A second electric push rod 251 is fixedly installed on the wall of the installation cavity 25. A motor 252 is fixedly installed on the output end of the second electric push rod 251. A matching rod 253 is fixedly installed on the output end of the motor 252 and the matching rod 253 is arranged between the mounting plates 221. The matching rod 253 is attached to the side of the mounting plate 221 close to the feeding group 211 by default. The matching rod 253 is a cylindrical rod of wear-resistant material with an I-shaped cross-section. The side of 53 is fixedly installed with stirring rods 254 in a staggered circular array at equal intervals, and the stirring rods 254 are attached to the wall of the inner cavity 22, and the stirring rods 254 are cylindrical rods; specifically, the second electric push rod 251 drives the motor 252 to drive the matching rod 253 to move inside the inner cavity 22, so that when the motor 252 drives the matching rod 253 to rotate, the stirring rod 254 can stir the release agent inside the inner cavity 22, and the mounting plate 221 can be driven to rotate and adjust the position through different positions of the matching rod 253, which can cause the feed group 211 to be blocked and stop the internal feeding;

[0045] The auxiliary component 3 can assist in the scraping of the release agent on the coated substrate film 43, and can cooperate with the composite film 44 and the substrate film 43 for composite operation to ensure the composite effect and quality;

[0046] like Figure 2 , Figure 9 andFigure 10 As shown, the auxiliary component 3 includes a fixed extrusion roller 31 rotatably installed inside the frame 11, and the height of the fixed extrusion roller 31 is flush with that of the movable guiding roller 13. An active extrusion roller 32 is rotatably installed at a position corresponding to the upper side of the fixed extrusion roller 31 inside the frame 11, and an active rectangular groove is formed at a position corresponding to the active extrusion roller 32 on the side of the frame 11. The fixed extrusion roller 31 and the active extrusion roller 32 are circular rollers with a heating function on their sides. A third electric push rod 33 is vertically and fixedly installed at a position corresponding to the active extrusion roller 32 inside the frame 11, and the output end of the third electric push rod 33 is rotatably connected to the side of the active extrusion roller 32 through a circular ring connecting piece. The third electric push rod 33 can drive the active extrusion roller 32 to move and adjust the position between it and the fixed extrusion roller 31. A connecting rod 34 is horizontally and fixedly installed on the side of the circular ring connecting piece at the output end of the third electric push rod 33. The connecting rod 34 is a rectangular rod. A scraping plate 35 is arranged on the side of the connecting rod 34 close to the movable guiding roller 13. The scraping plate 35 is a rectangular plate with a groove on its side. A first bolt group 351 is fixedly installed on the side of the connecting rod 34, and the first bolt group 351 is movably arranged on the side of the scraping plate 35. The first bolt group 351 is composed of a circular threaded rod and a nut. Specifically, after loosening the nut of the first bolt group 351, the scraping plate 35 can be constrained to adjust its position up and down on the side of the connecting rod 34, so that the scraping plate 35 can stably fit on the side of the base material film 43 to level the release agent on its side. Then, the nut of the first bolt group 351 is tightened to fix the scraping plate 35. In this way, the base material film 43 and the composite film 44 are subjected to composite extrusion operation by the fixed extrusion roller 31 and the active extrusion roller 32, and at the same time, the scraping plate 35 assists in leveling the release agent on the base material film 43.

[0047] The inner side of the frame 11 is symmetrically fixedly installed with a mounting block 36 corresponding to the position of the fixed squeezing roller 31. The mounting block 36 is a U-shaped block. Detection blocks 361 are provided on the upper and lower sides of the mounting block 36. The detection block 361 is a distance sensor (not described in detail in the present technical solution, and a model that can detect a small distance is sufficient). The detection block 361 can detect the distance of the clamping plate 37. A clamping plate 37 is symmetrically and movably installed on the inner side of the mounting block 36. The clamping plate 37 is a rectangular plate. A restraining rod 371 is symmetrically fixedly installed on the inner side of the mounting block 36 and the restraining rod 371 penetrates the clamping plate 37. The restraining rod 371 is a circular rod. A second spring 371 is fixedly connected between the inner side of the mounting block 36 and the side of the clamping plate 37 at the position corresponding to the detection block 361. 72. A slide groove 381 is provided on the mirror image of the side away from the splint 37. The slide groove 381 is a convex groove. A guide group 38 is symmetrically arranged on the side away from the splint 37. The guide group 38 is a "J"-shaped rectangular block and a heating module is arranged inside the guide group 38. A second bolt group 382 is movably installed inside the slide groove 381 and the second bolt group 382 passes through the center position of the guide group 38. The second bolt group 382 is composed of a "T"-shaped cylindrical threaded rod and a nut. By loosening the nut of the second bolt group 382, ​​it can slide inside the slide groove 381, driving the guide group 38 to adjust its position, and then the second bolt group 382; The nut is tightened to fix the guide group 38 to adapt to the production of release films of different specifications.

[0048] A method for using a release film composite device with adjustable specifications:

[0049] Before use: First, according to the width of the base film 43 and the composite film 44, loosen the second bolt group 382 to adjust the position of the guide group 38, and then tighten and fix the guide group 38;

[0050] In the second step, the coating assembly 2 is switched to the state of the required release force through the control cabinet 1. The second electric push rod 251 pushes the motor 252 by default to make the matching rod 253 fit the side of the mounting plate 221 close to the feeding group 211. The motor 252 drives the matching rod 253 to rub against the mounting plate 221 to make the trigger rod 231 slide inside the connecting cavity 23 to trigger the corresponding linkage rod 241. At this time, the matching rod 253 blocks the feeding group 211.

[0051] The trigger rod 231 slides inside the connecting cavity 23 to the first stage, such as Figure 11 As shown, at this time, in the position of the first trigger rod 231, the discharge hole 24 slides into the first group of first trigger grooves 232 and the first and third groups of third trigger grooves 234 on the side of the second group of trigger rods 231, and the discharge hole 24 is intermittently opened on the side of the coating roller 21, so that the coating roller 21 is in the shape of a gravure roller, and the side of the substrate film 43 is lightly coated with release force; the trigger rod 231 slides inside the connecting cavity 23 to the second stage, as shown in FIG. Figure 12As shown in the figure, at this time, in the position of a unit trigger rod 231, the discharge hole 24 slides out of the first trigger groove 232 on the side of the second group of trigger rods 231 and slides into the second trigger groove 233 on its side. The discharge hole 24 still remains in the third trigger groove 234 on the sides of the first group and the third group of trigger rods 231. The discharge holes 24 are opened in a grid diamond shape on the side of the coating roller 21, making the coating roller 21 in the shape of a gravure roller, and medium release force coating is carried out on the side of the base film 43; the trigger rod 231 slides to the third stage inside the connection cavity 23. At this time, in the position of a unit trigger rod 231, the discharge hole 24 slides into the first trigger groove 232 of the second group on the side of the second group of trigger rods 231 and still remains in the second trigger groove 233 on its side. The discharge hole 24 still remains in the third trigger groove 234 on the sides of the first group and the third group of trigger rods 231 and slides into the trigger rod 231 on its side. The discharge holes 24 are all opened on the side of the coating roller 21, making the coating roller 21 in the shape of a thick coating roller, and heavy release force coating is carried out on the side of the base film 43;

[0052] In the third step, place the base film 43 and the composite film 44 between the clamping plates 37. The elastic force provided by the second spring 372 is used to squeeze and fix the base film 43 and the composite film 44. The synchronous guiding group 38 is also clamped at the side position of the release film after the base film 43 and the composite film 44 are compounded. Install the compounded release film on the side of the first material roller 41 to complete the preparation for use;

[0053] During use: In the first step, the second electric push rod 251 is used to pull the motor 252 to separate the matching rod 253 from the side of the mounting plate 221. The external release agent is conveyed to the inner cavity 22 through the feeding group 211. The release agent flows into the connection cavity 23 through the inner cavity 22 and then is discharged from the discharge hole 24. Synchronously, the base film 43 is attached to the side of the coating roller 21 to contact the release agent for coating operation. Synchronously, the motor 252 drives the matching rod 253 to rotate, and the release agent can be stirred by the stirring rod 254;

[0054] In the second step, the clamping plates 37 are used to clamp the compounding position of the base film 43 and the composite film 44. The detection block 361 detects the distance change of the clamping plates 37 and feeds it back to the internal control module of the control cabinet 1. The compounding thickness of the base film 43 and the composite film 44 is judged according to the data, so that the control module controls the third electric push rod 33 to push and pull to adjust the distance between the movable pressing roller 32 and the fixed pressing roller 31, so that the fixed pressing roller 31 and the movable pressing roller 32 carry out heating and stable compounding operation on the base film 43 and the composite film 44. Synchronously, the position of the movable pressing roller 32 is adjusted, and the connecting rod 34 drives the scraper 35 to adjust the distance from the base film 43, so that the thickness of the release agent scraped by the scraper 35 matches the coating;

[0055] Among them, for the release film after the base film 43 and the composite film 44 are compounded, the side of the release film can be heated by being clamped by the guiding group 38, so that the release agent on the side of the release film can be quickly and preferentially cured, preventing the release agent from flowing out of the side of the release film. At the same time, the composite film 44 is attached to the side of the guiding group 38 to play a guiding and supporting role;

[0056] Third step, when switching production between release films with different release forces during production, the release film between the clamping plate 37 and the fixed extrusion roller 31 can be cut and disconnected by a cutter. At this time, the clamping plate 37 can clamp the release film. The control module of the control cabinet 1 is used to switch the state of the coating assembly 2. That is, at this time, the second electric push rod 251 pulls the motor 252 to make the matching rod 253 fit on the side of the mounting plate 221 away from the feeding group 211. The motor 252 drives the matching rod 253 to rotate and adjust the position of the trigger rod 231 inside the connection cavity 23. At this time, just pull the release film and install it on the side of the first material roller 41 to start the production and use of a new release film. Production switching can be carried out without changing the production, improving efficiency;

[0057] After use: First step, disassemble the first material roller 41 and the second material roller 42, cut the corresponding release film, and remove the base film 43 and the composite film 44;

[0058] Second step, convey the cleaning liquid into the inner cavity 22 through the feeding group 211. At this time, the coating assembly 2 is switched to fully open the discharge holes 24, and the inside of the coating roller 21 is cleaned and rinsed with the cleaning liquid. At the same time, the matching rod 253 rotates and stirs between the mounting plates 221 to enhance the cleaning effect. After completion, restore all components to the default state and cut off the power.
