DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 4 The utility model provides a deviation correction device for the production of polyurethane optical lens tape, including a U-shaped frame 2 and a deviation correction mechanism connected to the U-shaped frame 2. The bottom of the U-shaped frame 2 is connected to a base 1 for supporting the U-shaped frame 2. The deviation correction mechanism includes two deviation correction plates 11, two guide plates 10, and two cylinders 16. The deviation correction plate 11 is movably connected to the guide plate 10. The cylinder 16 is used to drive the deviation correction plate 11 to rise and fall. As the amount of tape rewinding by the rewinding roller 12 increases, the corresponding diameter also increases immediately, and the cylinder 16 can drive the deviation correction plate 11 to rise, so that the deviation correction plate 11 is always attached to both sides of the tape, which is convenient for the deviation correction operation. The guide plate 10 is connected to a driving mechanism for driving the two deviation correction plates 11 to move closer to or away from each other. The driving mechanism includes two push-pull plates 4, a turntable 6, and a motor 9. The motor 9 is used to drive the turntable 6 to rotate. The two ends of the push-pull plate 4 are connected to the turntable 6 and the corresponding guide plate 10. The U-shaped frame 2 is connected to a positioning mechanism for positioning the turntable 6.

[0022] During the tape reeling process, the deflection correcting plates 11 are located on both sides of the tape to prevent the tape from deviating. The motor 9 can drive the turntable 6 to rotate, and the turntable 6 simultaneously applies a push or pull force to the two push-pull plates 4, so that the two moving blocks 3 are synchronously moved closer or farther from each other, thereby achieving the two deflection correcting plates 11 to move closer or farther from each other, which can correct the tape from deviating during the reeling process and can be applied to tapes of different widths, and can be flexibly adjusted according to actual needs.

[0023] The deflection correction mechanism also includes two lifting blocks 17 and two connecting rods 18. The guide plate 10 is used to guide the lifting blocks 17. The two ends of the connecting rod 18 are connected to the lifting blocks 17 and the deflection correction plate 11. The end of the second cylinder 16 is connected to the guide plate 10, and the power output end of the second cylinder 16 is connected to the lifting block 17. The second cylinder 16 can drive the lifting block 17 to move up and down, and synchronously drive the connecting rod 18 to move, thereby realizing the lifting and lowering of the deflection correction plate 11. As the amount of tape winding increases, the position of the deflection correction plate 11 is adjusted at all times to make it fit on both sides of the tape.

[0024] The connecting rod 18 passes through the bottom of the guide plate 10 , and cooperates with the use of the lifting block 17 to improve the stability of the lifting of the deviation correcting plate 11 .

[0025] The driving mechanism also includes two moving blocks 3, which are movably connected to the U-shaped frame 2, and the bottom of the moving block 3 is connected to the guide plate 10, and the two ends of the push-pull plate 4 are connected to the moving block 3 and the turntable 6. When the turntable 6 rotates clockwise, a pulling force is applied to the two push-pull plates 4 simultaneously, and the push-pull plates 4 drive the corresponding moving blocks 3 to move in the direction close to the turntable 6, that is, the two correcting plates 11 are close to each other; when the turntable 6 rotates counterclockwise, a thrust is applied to the two push-pull plates 4 simultaneously, and the push-pull plates 4 drive the corresponding moving blocks 3 to move in the direction away from the turntable 6, that is, the two correcting plates 11 are away from each other, and the distance between the two correcting plates 11 can be flexibly adjusted according to the width of the tape.

[0026] The U-shaped frame 2 is provided with two guide holes 5, and the moving block 3 is slidably connected to the guide holes 5, so as to improve the stability of the movement of the moving block 3, that is, the guide plate 10 and the deviation correcting plate 11 move stably.

[0027] A rotating groove 7 is provided on the top of the U-shaped frame 2, and the turntable 6 is rotatably connected to the rotating groove 7. A motor 9 is connected to the bottom of the U-shaped frame 2, and the output shaft of the motor 9 is connected to the bottom center of the turntable 6. The rotating groove 7 makes the turntable 6 rotate stably.

[0028] The positioning mechanism includes a cylinder 8, a positioning head 19, and a push rod 20. The cylinder 8 is connected to the bottom of the U-shaped frame 2, and the power output end of the cylinder 8 is connected to the push rod 20, and the end of the push rod 20 is connected to the positioning head 19. When the turntable 6 is in a suitable position, the cylinder 8 drives the push rod 20 to move up, and the push rod 20 drives the positioning head 19 to move up, so that the positioning head 19 is connected to the corresponding positioning groove 21, so as to lock and fix the turntable 6.

[0029] A plurality of positioning grooves 21 are provided at the bottom of the turntable 6 . The positioning grooves 21 match the positioning heads 19 , and the cross-section of the positioning grooves 21 is an isosceles trapezoidal structure.

[0030] Two rotating shafts 14 are rotatably connected in the U-shaped frame 2, and the ends of the rotating shafts 14 are connected to connecting plates 13. The two ends of the winding roller 12 are connected to the connecting plates 13 by bolts, which is convenient for disassembly and assembly of the winding roller 12. The side of the U-shaped frame 2 is connected to a second motor 15, and the output end of the second motor 15 is connected to the rotating shaft 14. The second motor 15 can drive the rotating shaft 14 to rotate, and synchronously drive the winding roller 12 to rotate, so as to facilitate the winding of the tape.

[0031] Working principle: Motor 2 15 drives the winding roller 12 to rotate, which is convenient for winding the tape, and the two correcting plates 11 are attached to both sides of the tape, which is convenient for correcting the tape and avoiding deviation. When facing tapes of different widths, motor 1 9 drives the turntable 6 to rotate, and the turntable 6 applies thrust or pulling force to the two push-pull plates 4, and the push-pull plates 4 drive the corresponding moving blocks 3 to move, so that the two moving blocks 3 are close to or away from each other, so that the two correcting plates 11 are close to or away from each other, which can correct the deviation of the tape during the winding process and can be applied to tapes of different widths, and has strong applicability. When the correcting plate 11 is in a suitable position, cylinder 1 8 drives the push rod 20 to move up, and the push rod 20 drives the positioning head 19 to move up, so that the positioning head 19 is connected to the corresponding positioning groove 21, so as to lock and fix the turntable 6 and improve the stability of the two correcting plates 11.
