Description

Technical Field

[0001] The present invention relates to the technical field of film processing equipment, and in particular to a film constant tension regulating device and method. Background Art

[0002] In the film processing system, the tension control system occupies an important position. Constant tension control is an important guarantee for the processing of high-quality film products. The quality of tension control will affect the surface finish and thickness uniformity of the film, and directly determine the quality grade and yield rate of the film product. If the film tension is small, it is easy to slip horizontally between the film belt and the roller, affecting the coating effect; if the tension is large, the film belt will break under the stretching state.

[0003] Existing constant tension adjustment devices for films usually adjust the tension by changing the torque between rollers. However, during the film winding process, the momentary change in torque will cause a drastic change in the tension on the film. These momentary changes can easily cause the film to deform or even break. Summary of the invention

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Specifically, when the device is winding the film and needs to adjust the tension, the tension fine-tuning module 7 is used to make subtle and continuous adjustments to the tension applied to the film so that the tension meets the requirements. In the process of winding the film, the smoothing module 9 is used to smooth the wrinkles on the film. After the film is wound, the disassembly module 8 is used to quickly remove the winding roller 10 carrying the film on the shaft 6, and reinstall the unloaded winding roller 10 on the device; the device uses the tension fine-tuning module 7 to enable the device to adjust the tension on the film in a low-amplitude and high-frequency manner in the process of winding the film. The method of decomposing the total tension avoids the situation in which the film is pulled and damaged or even broken due to the drastic tension change caused by a one-time adjustment, thereby improving the yield and quality of the film products.

[0031] Reference Figure 3 , Figure 4 and Figure 5In a preferred embodiment, the outside of the fixed seat 704 is connected to the inner wall of the accommodating groove 702 by bolts, and two symmetrical movable seats 707 are arranged on the outside of the two-way threaded rod 703. The upper sides of the two movable seats 707 are rotatably connected with connecting rods 708 through bearings, and the ends of the connecting rods 708 away from the movable seat 707 are rotatably connected to the side of the connecting rod 708 on the same side close to the movable seat 707 through bearings; a stable seat 709 is arranged on the outside of the two-way threaded rod 703, and the stable seat 709 is located in the middle of the accommodating groove 702. A notch is provided on the stable seat 709, and a toothed ring 710 is provided in the notch. The inner wall of the toothed ring 710 is connected to the outside of the two-way threaded rod 703 by bolts, and a groove 711 is provided on the side of the rotating seat 701 away from the supporting bracket 4, and the groove 711 is provided A gear 712 is provided, which meshes with a gear ring 710. A motor 713 is provided on one side of the gear 712. The outside of the motor 713 is connected to the outside of the rotating seat 701 by bolts, and the output end of the motor 713 is connected to one side of the gear 712 by a coupling. Vertical slots 718 are provided on the two supporting brackets 4. The outside of the long rod 714 is rotatably connected to two symmetrical sliders 719 through bearings. The outsides of the two sliders 719 are respectively slidably connected to the inner walls of the two vertical slots 718, and a shock-absorbing pad 720 is bolted to the upper side of the connecting member 5. The upper side of the shock-absorbing pad 720 is bolted to a hydraulic rod 716. The output end of the hydraulic rod 716 is bolted to a locking member 717. The inner wall of the locking member 717 is bolted to the outside of the long rod 714.

[0032] Specifically, when the film tension needs to be adjusted, the motor 1 713 is started, and the motor 1 713 drives the gear ring 1 710 meshing with the gear 1 712 to rotate, so that the bidirectional threaded rod 703 drives the two moving seats 707 to move to both ends, and the connecting rod 708 on the moving seat 707 pushes the bracket 1 705 and makes the bracket 1 705 rotate outward, so that the bracket 2 706 connected to the bracket 1 705 rotates. Since the end of the bracket 2 706 away from the bracket 1 705 can only rotate on the long rod 714 and cannot move, the bracket 2 The angle between 706 and bracket 1 705 gradually increases, and bracket 1 705 pushes the long rod 714 connected to bracket 2 706 to move. The long rod 714 is set on the support frame 4, so that the device can adjust the distance between the support frame 4 and the manufacturing machine body 1, so that the tension of the film body 11 rolled up by the winding roller 10 on the support frame 4 changes. When a more subtle tension adjustment is required, the hydraulic rod 1 716 is started to push the long rod 714 to slide and rise on the vertical groove 718, thereby reducing the amplitude of the movement of the support frame 4 driven by the long rod 714.

[0033] In specific application scenarios, the tension fine-tuning module 7 is mainly suitable for the tension fine-tuning link in the tension fine-tuning process, that is, the tension fine-tuning module 7 uses the bidirectional threaded rod 703, the long rod 714 and the hydraulic rod 716 to enable the device to more effectively adjust the amplitude of the film tension change, so that the device can meet different film tension requirements while ensuring the efficiency and effect of tension adjustment.

[0035] Specifically, after the film body 11 on the winding roller 10 is wound up, the motor 2 804 is turned off, the rotating rod 808 is grasped and pushed upward, so that the rotating rod 808 overcomes the thrust of the spring 1 809 and retracts into the eccentric member 806, so that the limit groove 811 releases the lock on the rotating rod 808, and the rotating rod 808 is rotated counterclockwise to drive the eccentric member 806 to rotate. As the eccentric member 806 rotates, the long axis position of the eccentric member 806 no longer pushes the support platform 814 The support platform 814 drives the shaft 6 on the support platform 814 to rise and fall on the curved groove 801 and disengage the gear 2 805 from the gear ring 2 803.

[0037] Reference Figure 8 In a preferred embodiment, the smoothing module 9 includes two symmetrical support frames 901, and the two support frames 901 are respectively connected to the upper sides of the two supporting frames 4 by bolts. The upper sides of the two support frames 901 are connected to the same top plate 902 by bolts.

[0038] Specifically, after the tension during film winding is adjusted, the increase in tension may cause wrinkles on the film surface, and hydraulic rod 2 903 is started, which drives the mounting seat 904 to descend, so that the round rod 905 on the mounting seat 904 drives the spiral rubber plate 906 to contact the film body 11 and maintain a light pressure state, and motor 3 907 is started, which drives the two spiral rubber plates 906 to roll on the film body 11 in opposite directions, thereby pushing the wrinkles to the edge of the film body 11 and smoothing the film body 11.

By controlling the force of the spiral rubber plate 906 pressing down on the film body 11, the smoothing effect of the device on the film wrinkles is improved while ensuring that the film body 11 will not be damaged.

[0040] A film constant tension adjustment method, using the film constant tension adjustment device as described above, comprises the following steps:

[0041] Step 1: When the device is winding the film and needs to adjust the tension, use the tension fine-tuning module 7 to finely and continuously adjust the tension applied to the film so that the tension meets the requirements (when the film tension needs to be adjusted, start the motor 1 713, the motor 1 713 drives the gear ring 1 710 meshing with the gear 1 712 to rotate, so that the bidirectional threaded rod 703 drives the two moving seats 707 to move to both ends, and the connecting rod 708 on the moving seat 707 pushes the bracket 1 705 and makes the bracket 1 705 rotate outward, so that the bracket 2 706 connected to the bracket 1 705 rotates. Since the bracket 2 706 is away from the bracket 1 706, the bracket 1 706 is rotated. One end of bracket 05 can only rotate on long rod 714 but cannot move, so that the angle between bracket 2 706 and bracket 1 705 gradually increases and bracket 1 705 pushes long rod 714 connected to bracket 2 706 to move. Long rod 714 is arranged on support frame 4, so that the device can adjust the distance between support frame 4 and manufacturing machine body 1, so that the tension of film body 11 rolled up by winding roller 10 on support frame 4 changes. When more subtle tension adjustment is needed, hydraulic rod 1 716 is started to push long rod 714 to slide and rise on vertical slot 718, so as to reduce the amplitude of movement of support frame 4 driven by long rod 714);

[0042] Step 2: In the process of winding the film, use the smoothing module 9 to smooth the wrinkles on the film (after adjusting the tension when winding the film, the increase in tension may cause wrinkles on the film surface, start the hydraulic rod 2 903, the hydraulic rod 2 903 drives the mounting seat 904 to descend, so that the round rod 905 on the mounting seat 904 drives the spiral rubber plate 906 to contact the film body 11 and maintain a light pressure state, start the motor 3 907, the motor 3 907 drives the two spiral rubber plates 906 to roll on the film body 11 in opposite directions, so as to push the wrinkles to the edge of the film body 11 and smooth the film body 11);

[0043] Step 3: After the film is rolled up, use the disassembly module 8 to quickly remove the winding roller 10 carrying the film on the shaft 6, and reinstall the unloaded winding roller 10 on the device (after the film body 11 on the winding roller 10 is rolled up, turn off the motor 2 804, grab and push the rotating rod 808 upward, so that the rotating rod 808 overcomes the thrust of the spring 1 809 and retracts into the eccentric member 806, so that the limit groove 811 releases the lock on the rotating rod 808, and the rotating rod 808 is rotated counterclockwise to drive the eccentric member 806 to rotate. With the rotation of 806, the long axis position of the eccentric piece 806 no longer supports the support platform 814, so that the support platform 814 drives the shaft rod 6 on the support platform 814 to rise and fall in the curved groove 801 and disengage the gear 2 805 from the gear ring 2 803.
