Description

Technical Field

[0001] This invention belongs to the technical field of coating equipment, specifically a resin coating thickness control device. Background Technology

[0002] In fields such as composite materials, optoelectronic thin films, and flexible packaging, it is often necessary to uniformly coat resin between two thin films to form a stable sandwich structure (such as photovoltaic EVA film, optically transparent film, etc.). The uniformity of the thickness of the intermediate resin layer directly affects the light transmittance, bonding strength, and service life of the product.

[0003] Patent document CN121339147A discloses an automated coating sandwich device, relating to the field of coating sandwich production, comprising: a Pi film roll with a Pi film layer wound on it; a roller assembly including a coating roller for pressing material onto the Pi film; a material trough corresponding to the coating roller, the rotation of which causes the material layer in the trough to be bonded to the Pi film layer; and a calender for calendering the material output from the roller assembly; wherein the material, driven by the coating roller, is bonded to the Pi film in the roller assembly, and then transported to the calender for calendering and forming. This can improve production efficiency.

[0004] Existing equipment has certain shortcomings in resin sandwich coating operations. Sandwich coating (i.e., double-layer composite coating) is a process in which resin material is sandwiched between two thin films and the composite is completed during the synchronous movement of the films. However, this process has inherent drawbacks: the continuous compression of the resin between the two films causes the resin to overflow to both sides of the film, resulting in severe uneven coating thickness along the width direction; and the coating gap and baffle structure of traditional equipment are fixed, which cannot flexibly adjust the overall coating thickness according to the actual flow state of the resin, nor can it compensate for the edge overflow phenomenon. As a result, the thickness deviation accumulates continuously with production, ultimately leading to low product qualification rate, serious material waste, and difficulty in meeting the stringent requirements for thickness consistency in high-precision sandwich coating. Summary of the Invention

[0005] This invention provides a resin coating thickness control device, which solves the problem in the prior art where continuous compression of the intermediate resin by two layers of film causes resin to overflow to both sides of the film edges, resulting in severe uneven coating thickness along the width direction; and the problem that the coating gap and baffle structure of traditional equipment are fixed, which cannot flexibly adjust the overall coating thickness according to the actual flow state of the resin, nor can it compensate for the edge overflow phenomenon locally: A resin coating thickness control device includes a first roller and a second roller. The first roller is movably mounted on one side of the second roller. At least four sets of sliding bases are movably mounted on the upper part of the first roller and the second roller. The sliding bases are slidably connected to each other by slide rails. A baffle plate for use with the first roller and the second roller is installed at one end of each of the first and last sliding bases. The lower part of both sides of the baffle plate is an arc-shaped structure. The first roller and the second roller are connected by a fixing frame. The two ends of the second roller are slidably connected to the fixing frame by a docking slider.

[0006] As a further technical solution of the present invention, positioning rods are fixedly installed at the lower part of the other end of the sliding bases at both ends. The baffle plate is located on one side of the positioning rod, and the baffle plate and the positioning rod are distributed along the same straight line. In use, the position of the baffle plate is synchronously adjusted according to the width of the film. The two sets of films are conveyed by the second roller and the first roller respectively, so that the two sets of films pass through the gap between the second roller and the first roller and are discharged downward. By moving the sliding base, the sliding base synchronously drives the baffle plate and the positioning rod to move, and the two sets of positioning rods are moved to both sides of the film respectively. Because the baffle plate and the positioning rod are distributed along the same straight line, the baffle plate is located at the outer edge of the film. The nozzle and the thickness detector are installed through the two sets of sliding bases in the middle. The resin material is output downward by the nozzle, so that the resin material is placed between the first roller and the second roller. When the two sets of films move, the resin material is sandwiched between the two sets of films. The setting of the two sets of baffle plates has a sealing effect on both ends of the two sets of films, preventing the resin material from overflowing to both ends of the film.

[0007] As a further technical solution of the present invention, the lower part of the sliding base is provided with a clamping plate, and the sliding base and the clamping plate are movably connected by a fastening bolt. During operation, by rotating the fastening bolt, the fastening bolt drives the clamping plate to move up and down using the threaded structure, and the clamping plate completes the locking and fixing between the sliding base and the slide rail.

[0008] As a further technical solution of the present invention, the bottom of the slide rail is provided with a slide groove for use with the pressure plate, and the upper end of the pressure plate is provided with protrusions on both sides of the fastening bolt. The fastening bolt and the pressure plate are movably connected. When the fastening bolt rotates, the fastening bolt will not drive the pressure plate to rotate. At the same time, the mating between the protrusion and the slide groove plays an auxiliary positioning role in the use of the pressure plate.

[0009] As a further technical solution of the present invention, a rotating rod is provided in the middle of both the first roller and the second roller, and an electric push rod is provided on one outer surface of the fixed frame to cooperate with the second roller. By using the rotating rod structure, the first roller and the second roller can be rotated, and the electric push rod can be used to move the second roller horizontally with the use of the docking slider, thereby adjusting the distance between the second roller and the first roller and controlling the thickness of the resin material.

[0010] As a further technical solution of the present invention, a connecting seat is fixedly installed on one side of the docking slider, a guide rod is provided between the connecting seat and the electric push rod, the second roller and the docking slider are movably connected through a rotating rod, the docking slider and the fixed frame are slidably connected, and the fixed frame and the first roller are directly movably connected through a rotating rod. During operation, the connecting seat is driven by the electric push rod, so that the connecting seat moves along the direction of the guide rod, and the docking slider is driven by the connecting seat. The movement of the docking slider on the fixed frame drives the second roller to move.

[0011] As a further technical solution of the present invention, the baffle plate includes a fixed plate and a telescopic plate. The telescopic plate is movably installed on one side of the fixed plate. Both the fixed plate and the telescopic plate have arc-shaped grooves on the lower part of one side. By using the arc-shaped grooves, the lower parts of both sides of the baffle plate form an arc-shaped structure, so that the baffle plate matches the surface of the first roller and the second roller, thereby improving the sealing effect on the resin material. By moving the position of the telescopic plate, the position of the telescopic plate can be adjusted synchronously after the position of the second roller is adjusted, so that the baffle plate can meet the resin sealing needs of the first roller and the second roller at different spacings.

[0012] As a further technical solution of the present invention, the telescopic plate and the fixed plate are movably connected by an inner sleeve plate. The telescopic plate is movably sleeved on the outside of the inner sleeve plate, and the fixed plate and the inner sleeve plate are fixedly connected. During operation, the telescopic plate can be moved laterally by utilizing the movable connection between the inner sleeve plate and the telescopic plate, thereby adjusting the distance between the telescopic plate and the fixed plate to meet the synchronous position adjustment of the second roller.

[0013] As a further technical solution of the present invention, a lead screw is movably installed between the telescopic plate and the inner sleeve plate, the lead screw and the telescopic plate are movably connected, and the lead screw and the inner sleeve plate are threadedly connected. During operation, by rotating the lead screw, the lead screw drives the telescopic plate to move by utilizing the threaded connection between the inner sleeve plates. The movable connection between the telescopic plate and the lead screw ensures that the telescopic plate itself is not affected by the threaded structure.

[0014] As a further technical solution of the present invention, the upper end of the inner sleeve plate is provided with a limiting slide groove for use with the telescopic plate, and an installation block is fixedly installed at the middle position of the upper outer surface of the inner sleeve plate. A guide roller is provided on one side of the second roller. The fixed frame and the slide rail are fixedly connected. During operation, the installation block is used to complete the docking and fixing between the inner sleeve plate and the sliding base, so that the baffle plate is fixed at the lower position of the other end of the sliding base, and the guide roller plays a guiding and conveying role for the coated film material.

[0015] The beneficial effects of this invention are as follows: By setting two sets of baffles, the baffles can be moved by the sliding base during the use of the resin coating thickness control device. The baffle position can be flexibly adjusted according to the film width, effectively preventing the resin material from overflowing to the edges of the film and ensuring precise control of the coating area. At the same time, by adjusting the distance between the second roller and the first roller, the device can adapt to resin materials of different thicknesses for interlayer coating, realizing flexible setting and rapid switching of coating thickness, which significantly improves the equipment's adaptability to different product specifications and coating uniformity. During daily operation, the position of the baffle plate is synchronously adjusted according to the width of the film. Two sets of films are conveyed by the second and first rollers respectively, allowing them to pass through the gap between the second and first rollers and discharge downwards. Moving the sliding base synchronously moves the baffle plate and positioning rods, positioning the two sets of positioning rods to both sides of the film. Rotating the fastening bolts causes the threaded structure to move the pressure plate up and down, locking the sliding base and slide rail together. Because the baffle plate and positioning rods are aligned along the same straight line, the baffle plate is positioned at the outer edge of the film. The positioning rods, based on the film width, complete the positioning... The positioning of the baffle plate is achieved by installing the nozzle and thickness gauge on the two sets of sliding bases in the middle. The nozzle outputs resin material downwards, placing the resin material between the first and second rollers. When the two sets of films move, the resin material is sandwiched between them. The two sets of baffle plates seal the ends of the two sets of films, preventing the resin material from overflowing to the ends of the films. Next, the electric actuator drives the connecting seat, causing the connecting seat to move along the guide rod. The connecting seat drives the docking slider, and the movement of the docking slider on the fixed frame drives the second roller to move. By adjusting the distance between the second roller and the first roller, the thickness of the resin material is controlled. By setting a telescopic plate, the use of the baffle plate is optimized when the resin coating thickness control device is used, so that the baffle plate can be adjusted according to the position of the second roller, thereby meeting the baffle operation of resin materials with different thicknesses and improving its applicability. In use, the arc-shaped grooves create an arc-shaped structure on the lower sides of the baffle plate, allowing it to match the surfaces of the first and second rollers and improving the sealing effect on the resin material. By moving the telescopic plate, the position of the telescopic plate can be adjusted synchronously after the position of the second roller is adjusted, so that the baffle plate can meet the resin sealing needs of the first and second rollers at different spacings. By rotating the lead screw, the lead screw drives the telescopic plate to move through the threaded connection between the inner sleeve plates. The movable connection between the telescopic plate and the lead screw ensures that the telescopic plate itself is not affected by the threaded structure, allowing the telescopic plate to adjust accordingly to the position of the second roller.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1-4As shown, a resin coating thickness control device includes a first roller 1 and a second roller 2. The first roller 1 is movably mounted on one side of the second roller 2. At least four sets of sliding bases 3 are movably mounted on the upper part of the first roller 1 and the second roller 2. The sliding bases 3 are slidably connected to each other by slide rails 8. At one end of each of the first and last sliding bases 3, a baffle plate 11 is installed to cooperate with the first roller 1 and the second roller 2. The baffle plate 11 is fixed by bolts. The lower part of both sides of the baffle plate 11 is an arc-shaped structure. The first roller 1 and the second roller 2 are connected by a fixing frame 6. The two ends of the second roller 2 and the fixing frame 6 are slidably connected by a docking slider 13.

[0021] Positioning rods 12 are fixedly installed at the lower part of the other end of the sliding bases 3 at both ends. A baffle plate 11 is located on one side of the positioning rod 12. The baffle plate 11 and the positioning rod 12 are distributed along the same straight line. During use, the position of the baffle plate 11 is synchronously adjusted according to the width of the film. Two sets of films are conveyed by the second roller 2 and the first roller 1 respectively, allowing the two sets of films to pass through the gap between the second roller 2 and the first roller 1 and discharge downwards. By moving the sliding base 3, the sliding base 3 synchronously drives the baffle plate 11 and the positioning rod 12 to move, moving the two sets of positioning rods 12 to the two ends of the film respectively. On the side, because the baffle plate 11 and the positioning rod 12 are distributed along the same straight line, the baffle plate 11 is located at the outer edge of the film. The nozzle and the thickness detector are installed through the two sets of sliding bases 3 in the middle. The nozzle is installed at one end of the sliding base 3 and is located above the first roller 1 and the second roller 2. The resin material is output downward by the nozzle, so that the resin material is placed between the first roller 1 and the second roller 2. When the two sets of films move, the resin material is sandwiched between the two sets of films. The setting of the two sets of baffle plates 11 plays a role in sealing the two ends of the two sets of films, preventing the resin material from overflowing to the two ends of the film.

[0022] The lower part of the sliding base 3 is provided with a clamping plate 10. The sliding base 3 and the clamping plate 10 are movably connected by a fastening bolt 9. During operation, by rotating the fastening bolt 9, the fastening bolt 9 drives the clamping plate 10 to move up and down using the threaded structure. The clamping plate 10 completes the locking and fixing between the sliding base 3 and the slide rail 8.

[0023] The bottom of the slide rail 8 is provided with a groove for use with the pressure plate 10. The upper end of the pressure plate 10 is provided with protrusions on both sides of the fastening bolt 9. The fastening bolt 9 and the pressure plate 10 are movably connected. When the fastening bolt 9 rotates, the fastening bolt 9 will not drive the pressure plate 10 to rotate. At the same time, the mating between the protrusion and the groove plays an auxiliary positioning role in the use of the pressure plate 10.

[0024] Both the first roller 1 and the second roller 2 are provided with a rotating rod in the middle. The outer surface of one side of the fixed frame 6 is provided with an electric push rod 4 for use with the second roller 2. The rotating rod structure enables the first roller 1 and the second roller 2 to rotate. The electric push rod 4 can move the second roller 2 horizontally with the use of the docking slider 13, thereby adjusting the distance between the second roller 2 and the first roller 1 and controlling the thickness of the resin material.

[0025] A connecting seat 5 is fixedly installed on one side of the docking slider 13. A guide rod 14 is provided between the connecting seat 5 and the electric push rod 4. The second roller 2 and the docking slider 13 are movably connected through a rotating rod. The docking slider 13 is slidably connected to the fixed frame 6. The fixed frame 6 and the first roller 1 are directly movably connected through a rotating rod. During operation, the electric push rod 4 drives the connecting seat 5, causing the connecting seat 5 to move along the direction of the guide rod 14. The connecting seat 5 drives the docking slider 13. The movement of the docking slider 13 on the fixed frame 6 causes the docking slider 13 to drive the second roller 2 to move.

[0026] The baffle plate 11 includes a fixed plate 15 and a telescopic plate 16. The telescopic plate 16 is movably installed on one side of the fixed plate 15. Both the fixed plate 15 and the telescopic plate 16 have arc-shaped grooves 17 on the lower part of one side. The arc-shaped grooves 17 make the lower parts of both sides of the baffle plate 11 form an arc-shaped structure, so that the baffle plate 11 matches the surface of the first roller 1 and the second roller 2, improving the sealing effect on the resin material. By moving the position of the telescopic plate 16, the position of the telescopic plate 16 can be adjusted synchronously after the position of the second roller 2 is adjusted, so that the baffle plate 11 can meet the resin sealing needs of the first roller 1 and the second roller 2 at different spacings.

[0027] The telescopic plate 16 and the fixed plate 15 are movably connected by the inner sleeve plate 18. The telescopic plate 16 is movably sleeved on the outside of the inner sleeve plate 18, and the fixed plate 15 and the inner sleeve plate 18 are fixedly connected. During operation, the telescopic plate 16 can be moved laterally by utilizing the movable connection between the inner sleeve plate 18 and the telescopic plate 16, thereby adjusting the distance between the telescopic plate 16 and the fixed plate 15 to meet the synchronous position adjustment of the second roller 2.

[0028] A lead screw 19 is movably installed between the telescopic plate 16 and the inner sleeve plate 18. The lead screw 19 is movably connected to the telescopic plate 16, and the lead screw 19 is threadedly connected to the inner sleeve plate 18. During operation, by rotating the lead screw 19, the lead screw 19 drives the telescopic plate 16 to move through the threaded connection between the inner sleeve plate 18. The movable connection between the telescopic plate 16 and the lead screw 19 ensures that the telescopic plate 16 itself is not affected by the threaded structure.

[0029] The upper end of the inner sleeve plate 18 is provided with a limiting groove 20 for use with the telescopic plate 16, and an installation block 21 is fixedly installed at the middle position of the upper outer surface of the inner sleeve plate 18. A guide roller 7 is provided on one side of the second roller 2. The fixed frame 6 and the slide rail 8 are fixedly connected. During operation, the installation block 21 is used to complete the docking and fixing between the inner sleeve plate 18 and the sliding base 3, so that the baffle plate 11 is fixed at the lower position of the other end of the sliding base 3, and the guide roller 7 plays a guiding and conveying role for the coated film material.

[0030] A resin coating thickness control device, in use, synchronously adjusts the position of the baffle plate 11 according to the width of the film. Two sets of films are conveyed by the second roller 2 and the first roller 1 respectively, allowing them to pass through the gap between the second roller 2 and the first roller 1 and discharge downwards. By moving the sliding base 3, the baffle plate 11 and the positioning rods 12 are moved synchronously, positioning the two sets of positioning rods 12 to both sides of the film. By rotating the fastening bolt 9, the fastening bolt 9, through its threaded structure, moves the pressure plate 10 up and down, locking the sliding base 3 and the slide rail 8 together. Because the baffle plate 11 and the positioning rods 12 are distributed along the same straight line, the baffle plate 11 is positioned at the outer edge of the film, utilizing the positioning rods 12... Positioning of the baffle plate 11 is achieved by measuring the width of the film. The nozzle and thickness detector are installed through the two sets of sliding bases 3 in the middle. The resin material is output downward by the nozzle, so that the resin material is placed between the first roller 1 and the second roller 2. When the two sets of films move, the resin material is sandwiched between the two sets of films. The setting of the two sets of baffle plates 11 can seal the two ends of the two sets of films to prevent the resin material from overflowing to the two ends of the films. Next, the electric push rod 4 drives the connecting seat 5, so that the connecting seat 5 moves along the direction of the guide rod 14. The connecting seat 5 drives the docking slider 13. The movement of the docking slider 13 on the fixed frame 6 drives the docking slider 13 to move the second roller 2. The thickness of the resin material is controlled by adjusting the distance between the second roller 2 and the first roller 1. By utilizing the arc-shaped groove 17, the lower parts of both sides of the baffle plate 11 form an arc-shaped structure, allowing the baffle plate 11 to match the surfaces of the first roller 1 and the second roller 2, thus improving the sealing effect on the resin material. By moving the position of the telescopic plate, the position of the telescopic plate can be adjusted synchronously after the position of the second roller 2 is adjusted, so that the baffle plate 11 can meet the resin sealing needs of the first roller 1 and the second roller 2 at different spacings. By rotating the lead screw 19, the lead screw 19 drives the telescopic plate to move through the threaded connection between the inner sleeve plate 18. The movable connection between the telescopic plate and the lead screw 19 ensures that the telescopic plate itself is not affected by the threaded structure, allowing the telescopic plate to be adjusted accordingly according to the position of the second roller 2.

[0031] The above description is merely an example and illustration of the structure of the present invention.
