DETAILED DESCRIPTION
[0025] The technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.
[0026] Embodiment 1: please refer to Figure 1 、 Figure 2 and Figure 3 , the utility model provides a technical scheme:
[0027] A flattening device for plastic film production, comprising winding equipment 1, guide roller 2 and winding roller 3;
[0028] The winding roller 3 for winding is installed above the winding equipment 1, the plastic film 4 is wound outside the winding roller 3, and the guide roller 2 is rotatably connected with the winding equipment 1 outside the plastic film 4;
[0029] A leveling mechanism 5 is also provided on the outer side of the aforementioned plastic film 4, and both ends of the leveling mechanism 5 are fixedly connected to the moving plate 8. An adjustment mechanism 6, which is fixedly connected to the winding device 1, is fixedly connected to the outer side of the aforementioned moving plate 8.
[0030] The aforementioned leveling mechanism 5 includes a rotating shaft 501, a support sleeve 502, and a sponge sleeve 503. The two ends of the rotating shaft 501 are fixedly connected to bearings 504, and the outer side of the bearings 504 is fixedly connected to the movable plate 8.
[0031] A support sleeve 502 is fixedly connected to the outer side of the aforementioned rotating shaft 501, and a sponge sleeve 503 is fixedly connected to the outer side of both the aforementioned rotating shaft 501 and the support sleeve 502.
[0032] The outer side of the aforementioned support sleeve 502 is curved, and the support sleeve 502 is thicker in the center and thinner on both sides.
[0033] The aforementioned sponge sleeve 503 is cylindrical in shape, and the outer diameter of the sponge sleeve 503 is uniform.
[0034] Pressure sensors 505, which are evenly distributed and arranged in a circular trajectory, are installed in the central part of the support sleeve 502.
[0035] One side of the aforementioned movable plate 8 is raised, and the raised part of the aforementioned movable plate 8 is slidably connected to the guide groove 7 opened on the surface of the winding device 1.
[0036] Currently, plastic film products need to be wound up during production. The traditional winding method uses a winding roller to wind up the plastic film. Because the stress of the plastic film moves to both sides during winding, this winding method is prone to wrinkles. If not dealt with in time, it will seriously affect the winding quality. This device is powered by an external power source. A support sleeve 502 is set on the outside of the rotating shaft 501. The support sleeve 502 is thicker in the middle and thinner on both sides. A sponge sleeve 503 is set on the outside. During winding, the winding roller 3 rotates. At this time, the plastic film 4 moves and squeezes the sponge sleeve 503. Under the action of the support sleeve 502, the stress can be transferred to the outside, thereby achieving the purpose of flattening the plastic film 4 and achieving stable winding of the plastic film 4.
[0037] In this embodiment, during winding, the plastic film 4 squeezes the sponge sleeve 503 and simultaneously squeezes the bearing 504 on the outside of the support sleeve 502. When the detection data of the bearing 504 is within the set range, its adjustment mechanism 6 does not operate. When the detection data exceeds or falls below the set range, the adjustment mechanism 6 can drive the moving plate 8 to move, thereby moving the leveling mechanism 5. The position of the leveling mechanism 5 can be adjusted according to the degree of winding of the winding roller 3 to ensure stable use of the equipment. One side of the moving plate 8 has a protrusion that cooperates with the guide groove 7 to ensure that the moving plate 8 moves stably up and down. The support sleeve 502 and the sponge sleeve 503 cooperate to transfer stress to both sides when the plastic film 4 is wound, ensuring that the plastic film 4 is wound flat.
[0038] Example 2: This example is an improvement upon Example 1. Please refer to [link / reference]. Figure 4 Specifically, the adjustment mechanism 6 includes a mounting frame 601, a motor 602, and a threaded shaft 603. The outer side of the mounting frame 601 is fixedly connected to the winding device 1. The motor 602 is fixedly connected inside the mounting frame 601. The threaded shaft 603 is fixedly connected to the end of the main shaft of the motor 602. A movable sleeve 604 is spirally connected to the outer side of the threaded shaft 603. The other end of the movable sleeve 604 is fixedly connected to the movable plate 8.
[0039] The pressure sensor 505 sends a signal to the external control unit, which then controls the motor 602 to start, thereby driving the threaded shaft 603 to rotate. The threaded shaft 603 drives the outer threaded sleeve 604 to move, which in turn drives the moving plate 8 to slide. At this time, the orientation of the rotating shaft 501 can be adjusted to ensure that the winding roller 3 stably winds up the plastic film 4.
