Description

Technical Field

[0001] This utility model relates to the technical field of rewinding and slitting equipment, specifically a rewinding and slitting equipment for photovoltaic films. Background Technology

[0002] Photovoltaic encapsulant film is a key encapsulation material in solar photovoltaic modules, primarily used to wrap and protect the solar cells while ensuring efficient light transmission. Rewinding and slitting are crucial steps in the production and processing of photovoltaic encapsulant film. Rewinding involves rewinding the produced photovoltaic encapsulant film onto a specific reel for subsequent storage, transportation, and further processing; slitting involves cutting the wide photovoltaic encapsulant film to the dimensions required by the customer to obtain products that meet specifications.

[0003] In existing photovoltaic film rewinding equipment, the installation and disassembly of the rolls are often cumbersome. Traditional rewinding equipment typically has a fixed roll mounting structure. During installation, the small distance between the roll ends and the corresponding mounting points on the equipment, coupled with limited operating space, makes it difficult for workers to quickly and accurately insert the roll ends into the mounting holes, resulting in a time-consuming and inefficient installation process. Furthermore, after rewinding, removing the photovoltaic film from the roll is also inconvenient due to the tight fit between the roll and the mounting points, increasing the workload for workers and reducing overall production efficiency. Therefore, this paper proposes a photovoltaic film rewinding and slitting device. Utility Model Content

[0013] Preferably, the frame is hinged to a second cylinder on the side away from the second motor, and the push rod end of the second cylinder is hinged to a support plate hinged to one side of the frame. Two bearing seats are fixed on one side of the support plate. When one side of the bearing seat is rotatably connected to one end of the second and third air shafts, the photovoltaic film body is in a winding state.

[0014] Preferably, one side of the connecting frame is fixed to one side of the frame and the support frame respectively, a plurality of guide rollers are rotatably connected to the inner wall of the frame, one side of the photovoltaic film body is wrapped around the outside of the guide rollers, and the guide rollers are located at the bottom of the cutting assembly.

[0015] Preferably, the cutting assembly includes a fixing frame and a disassembly mechanism. The inner wall of the fixing frame is fixed with a first slide rod and a second slide rod respectively. A plurality of cutting blades are sleeved on the outer side of the first slide rod, and a plurality of sliders are sleeved on the outer side of the second slide rod.

[0020] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:

[0021] 1. Initially, the first cylinder push rod retracts, positioning the slide block in a specific position. This creates a larger distance between the two rotating seats, facilitating the insertion of the insertion shafts and rods at both ends of the first air expansion shaft into the first and second insertion holes of the corresponding rotating seats, enabling rapid installation. The first cylinder pushes the slide block to move, bringing the rotating seats closer together and accurately inserting both ends of the first air expansion shaft into the insertion holes, further ensuring installation accuracy. During rewinding, the second motor drives the second air expansion shaft to rotate, precisely rewinding the photovoltaic film onto the outside of the second air expansion shaft. The stable transmission mechanism ensures uniform tension during rewinding, avoiding problems such as loosening, wrinkling, or breakage of the photovoltaic film due to unstable transmission. This effectively guarantees the quality of the rewound photovoltaic film, improving product yield and consistency.

[0022] Second, by controlling the retraction of the second cylinder push rod end, the support plate is driven to rotate away from one end of the second and third air expansion shafts, making it convenient to wrap one end of the photovoltaic film body around the second or third air expansion shaft. After winding, the second cylinder push rod end extends, pushing the support plate to rotate, so that one side of the bearing seat is rotatably connected to one end of the second and third air expansion shafts to achieve support. After winding is completed, the second cylinder push rod end is retracted again, driving the support plate to rotate away, and the wound photovoltaic film body can be removed. The installation and disassembly process is convenient and efficient.

[0023] Third, by loosening the first bolt, the position of the movable slider on the second slide rod can be adjusted, thereby adjusting the position of the cutting blade on the first slide rod. This allows the position of the cutting blade to be flexibly adjusted according to different cutting needs, greatly improving the adaptability and flexibility of the equipment.

[0024] IV. When it is necessary to disassemble or assemble the cutting blade, simply loosen the second bolt, move the limit block and collar to expose the first and second through slots, and the slider and cutting blade can be taken out or installed from the through slots. This makes the disassembly and assembly of the cutting blade simple and quick, facilitates the maintenance and upkeep of the equipment, and makes it easy to replace different types of cutting blades according to production needs.

[0036] Example

[0037] Please see Figure 1-7 This utility model provides a technical solution: a rewinding and slitting device for photovoltaic encapsulant film, including a frame 1, a support frame 4 fixed on one side of the top of the frame 1, a photovoltaic encapsulant film body 7 on one side of the frame 1, an unwinding assembly 2 for the rewinding process of the photovoltaic encapsulant film body 7 on one side of the frame 1, a cutting assembly 5 for cutting the photovoltaic encapsulant film body 7 on one side of the unwinding assembly 2, and a winding assembly 3 for winding the photovoltaic encapsulant film body 7 on one side of the cutting assembly 5.

[0038] The unwinding assembly 2 includes a first motor 21 and a first cylinder 23. A slide 27 is fixed to the push rod end of the first cylinder 23. A rotating seat 22 is provided on both the output shaft end of the first motor 21 and one side of the slide 27. A first air expansion shaft 24 is provided between the two rotating seats 22. One side of one rotating seat 22 is fixed to the output shaft end of the first motor 21 and this rotating seat 22 is fixed to one side of the frame 1. One side of the other rotating seat 22 is rotatably connected to one side of the slide 27. A first insertion hole 29 and a second insertion hole 210 are respectively opened on one side of the rotating seat 22. The fit tolerance between the insertion rod 25 and the insertion shaft 28 and the first insertion hole 29 and the second insertion hole 210 is ≤0.05mm. Insertion rod 25 and insertion shaft 28 are fixed at both ends of the first air expansion shaft 24. A first slide rail 26 is fixed to the top of the support frame 4. The bottom of the slide 27 is slidably connected to the inner side of the track groove of the first slide rail 26.

[0039] One side of the first motor 21 is fixed to one side of the frame 1, and one side of the first cylinder 23 is fixed to one side of the support frame 4. When the insertion shaft 28 is inserted into the first insertion hole 29 and the insertion rod 25 is inserted into the inside of the second insertion hole 210, the first air shaft 24 is in the installation state. When the slide 27 moves, the direction of the insertion rod 25 and the insertion shaft 28 relative to the first insertion hole 29 and the second insertion hole 210 can be manually aligned to ensure that the insertion rod and the insertion hole are automatically aligned when moving.

[0040] The winding assembly 3 includes a connecting frame 32. A second motor 31 is fixed to one side of the top of the connecting frame 32. A second pulley 34 is fixed to the output shaft end of the second motor 31. The second pulley 34 is connected to a first pulley 33 via a belt. A second air shaft 35 and a third air shaft 36 are respectively fixed to the shaft center of one end of the first pulley 33 and the second pulley 34 via a rotating shaft.

[0041] A second cylinder 39 is hinged to the side of the frame 1 away from the second motor 31. The push rod end of the second cylinder 39 is hinged to a support plate 38 hinged to one side of the frame 1. Two bearing seats 37 are fixed on one side of the support plate 38. When the push rod end of the second cylinder 39 retracts, the support plate 38 rotates and moves away from one end of the second air shaft 35 and the third air shaft 36. At this time, the photovoltaic film body 7 after winding can be removed. When one side of the bearing seat 37 is rotatably connected to one end of the second air shaft 35 and the third air shaft 36, the fit tolerance between the bearing seat 37 and the second air shaft 35 and the third air shaft 36 is ≤0.05mm. When the push rod end of the second cylinder 39 retracts, the support plate 38 is driven to rotate around the hinge point of the frame 1 through the hinge structure, so that the bearing seat 37 is disengaged from the ends of the second air shaft 35 and the third air shaft 36.

[0042] When the photovoltaic encapsulant film body 7 is being wound and slit, after being slit by multiple cutting blades 59, the photovoltaic encapsulant film body 7 is wound in multiple parallel states on the surfaces of the second air expansion shaft 35 and the third air expansion shaft 36 respectively. When the second air expansion shaft 35 and the third air expansion shaft 36 are wound, paper core tubes need to be sleeved on the outside. By releasing the air pressure in the shaft body by releasing the air nozzle of the second air expansion shaft 35, the photovoltaic encapsulant film body 7 after being rewound and slit on the outside of the second air expansion shaft 35 can be quickly and safely removed.

[0043] One side of the connecting frame 32 is fixed to one side of the frame 1 and the support frame 4 respectively. Several guide rollers 6 are rotatably connected to the inner wall of the frame 1. One side of the photovoltaic film body 7 is wrapped around the outside of the guide rollers 6. The guide rollers 6 are located at the bottom of the cutting assembly 5. The guide rollers 6 play the role of guiding the transmission direction of the photovoltaic film body 7, ensuring that the photovoltaic film body 7 can smoothly enter the cutting assembly 5 and the winding assembly 3 to complete the corresponding operations.

[0044] The cutting assembly 5 includes a fixing frame 51 and a disassembly mechanism. The inner wall of the fixing frame 51 is fixed with a first slide rod 55 and a second slide rod 56 respectively. Several cutting blades 59 are sleeved on the outer side of the first slide rod 55, and several sliders 57 are sleeved on the outer side of the second slide rod 56. A first bolt that abuts against one side of the second slide rod 56 is threaded to one side of the slider 57. One side of the slider 57 is fixed to one side of the cutting blade 59. A limit plate 52 is fixed to the top of the inner wall of the frame 1. A third cylinder 53 is fixed to the bottom of the limit plate 52. The push rod end of the third cylinder 53 is fixed to the top of the fixing frame 51. A second slide rail 514 is fixed to both sides of the inner wall of the frame 1. The two sides of the fixing frame 51 are slidably connected to the inner side of the track groove of the second slide rail 514.

[0045] The disassembly mechanism includes a third slide rod 512 and a fourth slide rod 515. A limiting block 58 is sleeved on the outside of the fourth slide rod 515. A second bolt that abuts against the side of the second slide rod 56 is threaded onto one side of the limiting block 58. A sliding plate 511 is fixed to one end of the third slide rod 512. A collar 513 is slidably connected to the outside of the sliding plate 511. One side of the collar 513 is fixed to one side of the limiting block 58. One end of both the third slide rod 512 and the fourth slide rod 515 is fixed to one side of the inner wall of the fixing frame 51. A first through groove 54 is provided between the first slide rod 55 and the third slide rod 512. A second through groove 510 is provided between the second slide rod 56 and the fourth slide rod 515. When the limiting block 58 and the collar 513 move to one side to expose the first through groove 54 and the second through groove 510, the slider 57 and the cutting blade 59 are in the disassembly / reassembly state.

[0046] Working principle: Initially, the push rod end of the first cylinder 23 is in the retracted state, and the slide 27 is located at the end of the first slide rail 26 away from the first motor 21. At this time, the distance between the two rotating seats 22 is large, which facilitates the installation of the first air expansion shaft 24. The insertion shafts 28 and insertion rods 25 at both ends of the first air expansion shaft 24 are inserted into the inner side of the first insertion hole 29 and the second insertion hole 210 of the corresponding rotating seat 22, respectively, to realize the installation of the first air expansion shaft 24. The first cylinder 23 pushes the slide 27 to move, so that one rotating seat 22 is close to the other rotating seat 22, and the two ends of the first air expansion shaft 24 are accurately inserted into the insertion holes of the rotating seat 22 to complete the installation.

[0047] Start the first motor 21. The output shaft of the first motor 21 drives the rotating seat 22 fixed to it to rotate. Since the two rotating seats 22 are connected by the first air expansion shaft 24, the first air expansion shaft 24 rotates accordingly. After the photovoltaic film body 7 wrapped around the outside of the first air expansion shaft 24 is wrapped around the outside of the guide roller 6, the paper core tube is sleeved on the outside of the second air expansion shaft 35 located at the bottom, and one end of the photovoltaic film body 7 is connected to the paper core tube. The power of the second motor 31 drives the second air expansion shaft 35 to rotate, so that the photovoltaic film body 7 is rewound to the outside of the second air expansion shaft 35. After the rewinding is completed, the push rod end of the second cylinder 39 is retracted, which drives the support plate 38 to rotate away from one end of the second air expansion shaft 35. The air pressure in the shaft body is released by the air nozzle of the second air expansion shaft 35, and the photovoltaic film body 7 rewound to the outside of the second air expansion shaft 35 can be removed.

[0048] The second cylinder 39 retracts its push rod, causing the support plate 38 to rotate and move away from one end of the second and third air shafts 35 and 36. This facilitates the connection of the photovoltaic film body 7 and the paper core tube to the second or third air shaft 35 or 36. After one end of the photovoltaic film body 7 is wound around the second or third air shaft 35 or 36, the push rod of the second cylinder 39 extends, pushing the support plate 38 to rotate. This causes one side of the bearing seat 37 to rotate and connect to one end of the second or third air shaft 35 or 36, providing support. The second motor 31 is then started. The output shaft of the second motor 31 drives the second pulley 34 to rotate, which in turn drives the first pulley 33 to rotate via belt drive. This, in turn, drives the second and third air shafts 35 and 36 to rotate, thus winding up the photovoltaic film body 7 after it has been cut by the cutting component 5. During the cutting of the photovoltaic film body 7, the photovoltaic film bodies 7 cut by multiple cutting blades 59 are staggered and fixed on the surfaces of the upper and lower second and third air shafts 35 and 36. After winding is completed, the push rod end of the second cylinder 39 is retracted again, causing the support plate 38 to rotate away from one end of the second air expansion shaft 35 and the third air expansion shaft 36, so that the wound photovoltaic film body 7 can be removed.

[0049] By loosening the first bolt, the position of the movable slider 57 on the second slide bar 56 can be adjusted, thereby adjusting the position of the cutting blade 59 on the first slide bar 55 to adapt to different cutting needs. After adjustment, tighten the first bolt to fix the positions of the slider 57 and the cutting blade 59. When cutting is required, the push rod end of the third cylinder 53 extends and pushes the fixing frame 51 to move downward along the second slide rail 514, which in turn drives the cutting blade 59 to move downward to cut the photovoltaic film body 7.

[0050] When it is necessary to disassemble or assemble the cutting blade 59, loosen the second bolt, move the limiting block 58 and the collar 513 to expose the first through groove 54 and the second through groove 510. At this time, the slider 57 and the cutting blade 59 can be removed or installed from the first through groove 54 and the second through groove 510 to realize the disassembly and assembly of the cutting blade 59, which facilitates flexible adjustment of the cutting scheme according to production needs.

[0051] In summary, by initially retracting the first cylinder 23, the slide 27 is positioned in a specific location, resulting in a larger distance between the two rotating seats 22. This facilitates the insertion of the insertion shafts 28 and insertion rods 25 at both ends of the first air expansion shaft 24 into the inner sides of the first insertion holes 29 and second insertion holes 210 of the corresponding rotating seats 22, enabling rapid installation. The first cylinder 23 pushes the slide 27 to move, bringing the rotating seats 22 closer together and accurately inserting both ends of the first air expansion shaft 24 into the insertion holes, further ensuring installation accuracy. During rewinding, the power of the second motor 31 drives the second air expansion shaft 35 to rotate, precisely rewinding the photovoltaic film body 7 to the outside of the second air expansion shaft 35. The stable transmission mechanism ensures uniform tension during the rewinding process, avoiding problems such as loosening, wrinkling, or breakage of the photovoltaic film body 7 caused by unstable transmission. This effectively guarantees the quality of the photovoltaic film body 7 after rewinding, improving the product yield and consistency.

[0052] By controlling the retraction of the push rod end of the second cylinder 39, the support plate 38 is rotated away from one end of the second air expansion shaft 35 and the third air expansion shaft 36, making it convenient to wrap one end of the photovoltaic film body 7 around the second air expansion shaft 35 or the third air expansion shaft 36. After winding, the push rod end of the second cylinder 39 extends and pushes the support plate 38 to rotate, so that one side of the bearing seat 37 is rotatably connected to one end of the second air expansion shaft 35 and the third air expansion shaft 36 to achieve support. After winding is completed, the push rod end of the second cylinder 39 is retracted again, causing the support plate 38 to rotate away, and the wound photovoltaic film body 7 can be removed. The installation and disassembly process is convenient and efficient.

[0053] By loosening the first bolt, the position of the movable slider 57 on the second slide bar 56 can be adjusted, thereby adjusting the position of the cutting blade 59 on the first slide bar 55. This allows the position of the cutting blade 59 to be flexibly adjusted according to different cutting requirements, greatly improving the adaptability and flexibility of the equipment.

[0054] When it is necessary to disassemble or assemble the cutting blade 59, simply loosen the second bolt, move the limit block 58 and the collar 513 to expose the first through groove 54 and the second through groove 510, and the slider 57 and the cutting blade 59 can be taken out or installed from the through groove. This makes the disassembly and assembly process of the cutting blade 59 simple and quick, facilitates the maintenance and upkeep of the equipment, and also makes it easy to replace different types of cutting blades 59 according to production needs.
