Description

Technical Field

[0001] This utility model relates to the field of PET sheet winding technology, and in particular to a PET sheet winding and correction device. Background Technology

[0002] In the PET sheet manufacturing and processing industry, the winding process is a crucial step in ensuring product quality and subsequent processing efficiency. PET sheets, due to their excellent transparency, impact resistance, and chemical stability, are widely used in packaging, electronics, optics, and other industries. During the winding process, the sheet must be neatly wound around the winding drum. If the sheet shifts laterally, the edges of the wound material will be uneven, affecting not only the product's appearance but also creating difficulties for subsequent cutting and laminating processes. Therefore, a specialized PET sheet winding and correction device is needed to adjust the sheet's transport path, ensuring a stable and orderly winding process and meeting the precision requirements of industrial production.

[0003] Existing PET sheet winding and correction devices mostly use a structure with side guide rollers and cylinder drive to achieve the correction function. The technical principle is to use photoelectric sensors to detect the edge position of the sheet. When the sheet is detected to be off, the sensor transmits the signal to the controller. The controller controls the cylinder to push the side guide roller to move. The lateral thrust of the guide roller on the sheet is used to adjust the conveying direction of the sheet. Some devices also use a screw drive mechanism. The motor drives the screw to rotate, which drives the slider that cooperates with the screw to move, thereby pushing the guide component to correct the position of the sheet, so as to achieve the purpose of correction when winding the sheet.

[0004] However, existing PET sheet winding and correction devices are difficult to effectively ensure that the sheet is always in the center of the winding drum during practical applications. Especially when processing PET sheets of different widths and thicknesses, the existing devices have limited adjustment range and poor adaptability due to the limited adjustment range of the correction structure. This can easily lead to sheet winding deviation, resulting in uneven edges of the wound material. This not only affects the normal operation of subsequent processing steps but also reduces the product qualification rate, causing certain production cost losses for enterprises. Therefore, a PET sheet winding and correction device is proposed to solve the above problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-3 This utility model provides an embodiment of a PET sheet winding and correction device, comprising a winding frame 1, which serves as the support frame for the entire device. The winding frame 1 is welded from high-strength Q235 steel plate, and its bottom is welded with anti-slip feet to provide stable support for the entire winding and correction device, preventing displacement due to vibration during operation and ensuring stable winding operations. A winding drum 3 is rotatably connected inside the winding frame 1. The winding drum 3 has a hollow cylindrical structure, and its outer wall is coated with a wear-resistant epoxy resin coating to reduce wear. To reduce frictional damage during PET sheet winding and prevent the sheet from sticking to the outer wall of the winding drum 3, a winding motor 2 is fixedly connected to the outer wall of the winding frame 1. The winding motor 2 used in this application is a 1LE0001 series three-phase asynchronous motor manufactured by Shanghai Siemens, with a power of 1.5kW to 5kW, used to provide rotational power for the winding drum 3. This is existing technology and will not be described in detail here. The output end of the winding motor 2 passes through the winding frame 1 and is fixedly connected to one end of the winding drum 3. A correction component is provided on the top of the winding drum 3. The correction assembly includes two correction plates 4, each a rectangular steel plate with a silicone buffer layer adhered to the side closest to the sheet. This buffer layer prevents hard contact that could damage the sheet edges during sheet positioning and enhances adhesion, thus improving the correction effect. The outer wall of the correction plate 4 is fitted into the top of the winding drum 3 via a slot, allowing its position to be adjusted synchronously with the sheet winding progress. A fixing frame 5 is fixedly connected inside the winding frame 1. The fixing frame 5 is a rectangular frame structure made of stainless steel, providing excellent load-bearing capacity and corrosion resistance. It is used to install and fix the drive motor 12, the correction assembly, and other components. The fixing frame 5 contains the correction assembly and a drive motor 12. A transmission rod 11 is fixedly connected to the output end of the drive motor 12. The outer wall of the transmission rod 11 is rotatably connected inside the fixing frame 5. Rotating rods 10 are rotatably connected to both sides of the transmission rod 11. 10. A connecting column 9 is rotatably connected to the other side. A connecting plate 7 is fixedly connected to the top of the connecting column 9. The outer wall of the correction plate 4 is set inside the connecting plate 7. The connecting plate 7 is equipped with a disassembly and assembly assembly. The limiting assembly includes a limiting rail 6, which is a T-shaped guide rail structure made of 45# steel with heat treatment, and has high hardness and wear resistance. The bottom of the limiting rail 6 is fixedly connected to the top of the fixing frame 5 by bolts to ensure that the limiting rail 6 is installed firmly. The connecting plate 7 has a T-shaped groove that matches the limiting rail 6. Its outer wall is slidably connected to the outer wall of the limiting rail 6 through the T-shaped groove. The limiting rail 6 slides and guides the connecting plate 7 with the T-shaped groove, thereby limiting the connecting plate 7 to move only in the horizontal direction and preventing it from shifting up and down. The bottom of the limiting rail 6 is fixedly connected to the top of the fixing frame 5. The outer wall of the connecting plate 7 is slidably connected to the outer wall of the limiting rail 6. The fixing frame 5 has a moving groove 8. The outer wall of the connecting column 9 is slidably connected to the moving groove 8.

[0020] Reference Figure 1 , Figure 4 and Figure 5The assembly and disassembly components include a locking post 16, which is a cylindrical structure made of 45# steel with a chrome-plated surface, providing good wear resistance and rust prevention. It is used to insert into the alignment plate 4 for fixation. The outer wall of the locking post 16 is slidably connected to the connecting plate 7 via a clearance fit. This clearance fit ensures that the locking post 16 slides freely within the connecting plate 7, preventing jamming. The connecting plate 7 has a slot 17, and the outer wall of the alignment plate 4 is slidably connected to the slot 17. The connecting plate 7 also has a limiting groove 15, which is rectangular and its length is related to the sliding motion of the connecting plate 18. The stroke is matched to limit the movement trajectory of the connecting plate 18, ensuring that the connecting plate 18 moves only in the horizontal direction. The connecting plate 7 is slidably connected to the connecting rod 14. One end of the connecting rod 14 is rotatably connected to the pull ring 13. The pull ring 13 has a U-shaped structure and is made of stainless steel. Its outer wall is fitted with a silicone anti-slip sleeve to facilitate the operator's grip and force application, while preventing hand slippage. Multiple connecting plates 18 are fixedly connected to the outer wall of the connecting rod 14. The outer wall of the connecting plate 18 is slidably connected to the inside of the limiting groove 15. One end of the locking post 16 is fixedly connected to one side of the connecting plate 18. The outer wall of the connecting rod 14 is fitted with a spring 19. One end of the spring 19 is fixedly connected to the connecting plate 18, and the other end of the spring 19 is fixedly connected to the inner wall of the connecting plate 7.

[0021] Working principle: When winding PET sheets, the winding motor 2 is started first. The power output of the winding motor 2 directly drives the winding drum 3 connected to it to rotate at a constant speed along a fixed axis. The sheet is gradually wound around the outer wall of the winding drum 3 under the conveying mechanism, so as to achieve orderly winding. To prevent lateral shift of the sheet material during winding due to transmission deviations and tension fluctuations, the drive motor 12 can be started synchronously. After the drive motor 12 starts running, it drives the transmission rod 11 connected to its output end to rotate. Since the two ends of the transmission rod 11 are connected to the two rotating rods 10 on both sides through gears or couplings, the rotation of the transmission rod 11 will synchronously drive the two rotating rods 10 to rotate in the same direction. When the rotating rod 10 rotates, the threaded structure or cam structure on its outer wall will drive the connecting column 9 to slide smoothly inside the preset moving groove 8. The top of the connecting column 9 is fixedly connected to the connecting plate 7, which in turn drives the connecting plate 7 to slide along the outer wall of the limiting rail 6. The guiding effect of the limiting rail 6 can ensure that the connecting plate 7 always maintains a straight line movement and avoids deviation. The two side correction plates 4 connected to the connecting plate 7 will slide synchronously against the two sides of the sheet material. Through physical limiting, the sheet material is limited to the middle winding area of ​​the winding drum 3, which effectively prevents the sheet material from shifting left and right during winding and ensures that the edge of the roll is neat.

[0022] When the alignment plate 4 shows signs of wear and dirt buildup after long-term use and requires maintenance and cleaning, the operator can directly pull the pull ring 13 on the outside of the device. After the pull ring 13 is under force, it drives the connecting rod 14 fixed to it to slide horizontally. The two ends of the connecting rod 14 are respectively hinged to the two connecting plates 18. Its sliding will drive the two connecting plates 18 to slide towards each other in the corresponding limiting grooves 15. During the sliding process of the connecting plates 18, it will compress the spring 19 sleeved on its outside, so that the spring 19 is in a compressed state. At the same time, the end of the connecting plate 18 away from the connecting rod 14 is fixedly connected to the locking post 16. The sliding of the connecting plate 18 will simultaneously drive the locking post 16 to slide completely out of the locking groove at the bottom of the alignment plate 4. At this time, the fixed relationship between the alignment plate 4 and the installation structure is released, and the operator can pull the alignment plate 4 out horizontally from the slot 17 for maintenance, cleaning or replacement. After maintenance, reinsert the alignment plate 4 into the slot 17, ensuring its alignment, and then release the pull ring 13; the compressed spring 19 will quickly rebound, pushing the two connecting plates 18 to slide in opposite directions inside the limiting groove 15, thereby driving the locking pin 16 to slide back into the locking groove of the alignment plate 4, thus achieving a stable fixation of the alignment plate 4 and ensuring the stable operation of subsequent winding and alignment work.
