Detailed Implementation
[0021] like Figures 1-2 As shown, a film winding device according to this application includes a frame 1, a flipping frame 2 mounted on the frame 1, and the film winding device also includes a flattening roller 3, a traction mechanism 4, a transition roller 5, a tension adjustment mechanism 6, a winding mechanism 7, a cutting mechanism 8, a film coating pressure roller 9, and a gap adjustment mechanism 10.
[0022] Specifically, the flattening roller 3 is located at the top of the frame 1 and connected to the frame 1; the traction mechanism 4 and the tension adjustment mechanism 6 are located at the upper part of the frame 1 and connected to the frame 1; the transition roller 5 is located at the middle part of the frame 1 and connected to the frame 1; the gap adjustment mechanism 10 is located at the lower part of the frame 1 and connected to the frame 1; the film-coating roller 9 and the cutting mechanism 8 are slidably connected to the gap adjustment mechanism 10. The gap adjustment mechanism 10 includes a guide rail 101 and a guide member 102 adapted to the guide rail 101. The film-coating roller 9 and the cutting mechanism 8 are connected to the guide member 102. The gap adjustment mechanism 10 is configured to move the film-coating roller 9 and the cutting mechanism 8 towards the turning frame 2 or away from the turning frame 2.
[0023] The winding mechanism 7 is mounted on the flipping frame 2 and includes a first winding shaft 71, a first guide roller 72, a second winding shaft 73, and a second guide roller 74. The first winding shaft 71, the first guide roller 72, the second winding shaft 73, and the second guide roller 74 are alternately mounted on the flipping frame 2. The first winding shaft 71 is electrically connected to a first motor, and the second winding shaft 73 is electrically connected to a second motor.
[0024] Specifically, since the winding mechanism 7 includes a first winding shaft 71, a first guide roller 72, a second winding shaft 73, and a second guide roller 74, the film winding device described in this application has two winding stations. During winding, it is necessary to adjust the relative position of the winding station and the frame 1. Therefore, a flipping shaft is provided on the flipping frame 2. The flipping shaft is electrically connected to a power component, which can be a motor or other power mechanism capable of driving the flipping shaft. The winding mechanism 7 is connected to the flipping shaft. Driven by the power component, the flipping shaft drives the winding mechanism 7 to flip, thereby adjusting the relative position of the winding station and the frame 1 so that the winding station is in a suitable position when the film winding device described in this application is winding. Furthermore, by rationally setting the dimensions of the winding mechanism 7 and the positions of the first winding shaft 71, the first guide roller 72, the second winding shaft 73, and the second guide roller 74, the maximum roll diameter of the film winding device described in this application is 800 mm, which is the diameter of each roll of substrate after winding. At the same time, due to the characteristics of the substrate, the maximum winding linear speed of the film winding device described in this application can reach 120 m / min during winding, which is fast and thus improves the winding efficiency.
[0025] During substrate winding, the flipping frame 2 flips the winding mechanism 7, bringing the first guide roller 72 closer to the coating roller 9 and the first winding shaft 71 closer to the tension adjustment mechanism 6. The gap adjustment mechanism 10 adjusts the distance between the coating roller 9 and the first guide roller 72. The cooperation between the coating roller 9 and the first guide roller 72 makes the substrate flatter when it enters the first winding shaft 71. The substrate passes through the flattening roller 3, traction mechanism 4, transition roller 5, tension adjustment mechanism 6 and coating roller 9 set on the frame 1 in sequence before entering the flipping frame 2. It is then wound up by the first winding shaft 71. After winding, the cutting mechanism 8 cuts the substrate. The flipping frame 2 flips the winding mechanism 7, bringing the second guide roller 74 closer to the coating roller 9 and the second winding shaft 73 closer to the tension adjustment mechanism 6. The substrate passes through the flattening roller 3, traction mechanism 4, transition roller 5, tension adjustment mechanism 6 and coating roller 9 set on the frame 1 in sequence before entering the flipping frame 2. It is then wound up by the second winding shaft 73. The substrate is wound up cyclically.
[0026] More specifically, the substrate is wound up sequentially through the flattening roller 3, the traction mechanism 4, the tension adjustment mechanism 6, the coating pressure roller 9, and the winding mechanism 7. The cooperation between the coating pressure roller 9 and the first guide roller 72 / second guide roller 74 further flattens the substrate, preventing wrinkles from reappearing during the winding process, thereby improving the winding effect.
[0027] Furthermore, the gap adjustment mechanism 10 described in this application is used to adjust the gap between the film-coating roller 9 and the first guide roller 72 / second guide roller 74. The gap adjustment mechanism 10 also includes a third motor and a transmission component. The third motor is connected to the transmission component, and the guide component 102 is slidably disposed on the guide rail 101, with one part of the guide component 102 connected to the transmission component.
[0028] Specifically, the guide rail 101 is in the shape of an "I", the bottom of the guide member 102 is adapted to the groove of the guide rail 101, and the bottom of the guide member 102, away from the guide rail 101, extends downward to form a structure connected to the transmission member. For example, the transmission member is a gear, and the guide member 102 is provided with a toothed structure adapted to the gear at the point of engagement with the gear.
[0029] Furthermore, the tension adjustment mechanism 6 includes a float roller 61, a guide roller 62, and an adjustment member 63. The float roller 61 is connected to the adjustment member 63, and the guide roller 62 is connected to the float roller 61.
[0030] Specifically, the float roller 61 is typically made of an elastic material; for example, the float roller 61 can be made of rubber or polyurethane. The main function of the float roller 61 is to provide appropriate support and friction to help the material remain flat during winding; the tension adjustment mechanism 6 ensures smooth movement of the substrate during winding, improving winding quality and efficiency.
[0031] More specifically, the adjusting element 63 is a cylinder or a hydraulic cylinder, preferably a cylinder.
[0032] Furthermore, the cutting mechanism 8 includes a cutting body 81, a driving member 82, and a connecting member 83. The cutting body 81 is connected to the driving member 82, and the connecting member 83 is connected to the guide member 102. The connecting member 83 is also connected to the cutting body 81. That is, the cutting body 81 is connected to the guide member 102 through the connecting member 83.
[0033] Preferably, since the winding process requires adjusting the gap between the coating roller 9 and the first guide roller 72 or the coating roller 9 and the second guide roller 74, and after the gap is adjusted, the cutting mechanism 8 is used to cut the substrate after winding, in order to avoid the frequent use of the gap adjustment mechanism to adjust and affect the winding efficiency, the connecting piece 83 is connected to the coating roller 9 on the same shaft, which is connected to the guide piece 102, connecting the cutting mechanism 8 and the coating roller 9 on the same shaft. After winding is completed, the substrate is directly cut by the cutting mechanism 8, thereby improving the winding efficiency.
[0034] Furthermore, the traction mechanism 4 includes a steel roller 41 and a rubber roller 42, which are arranged opposite to each other, and a traction gap is left between the steel roller 41 and the rubber roller 42.
[0035] Furthermore, the film winding device of this application also includes a connecting frame, which is disposed on the top of the frame 1 and connected to the frame 1; the end of the flattening roller 3 is connected to the connecting frame.
[0036] The working process of the film winding device described in this application is as follows:
[0037] Taking the winding process via the first take-up shaft 71 as an example, the flipping frame 2 flips the winding mechanism 7, bringing the first guide roller 72 closer to the coating roller 9 and the first take-up shaft 71 closer to the tension adjustment mechanism 6. The gap adjustment mechanism 10 adjusts the distance between the coating roller 9 and the first guide roller 72. The cooperation between the coating roller 9 and the first guide roller 72 makes the substrate flatter when it enters the first take-up shaft 71. The substrate then passes sequentially through the flattening roller 3, the traction mechanism 4, the transition roller 5, the tension adjustment mechanism 6, and the tension adjustment mechanism 6, all mounted on the frame 1. After the coating roller 9 enters the flipping frame 2, it is wound up by the first winding shaft 71. After winding, the cutting mechanism 8 cuts the substrate, and the flipping frame 2 flips the winding mechanism 7 so that the second guide roller 74 is close to the coating roller 9 and the second winding shaft 73 is close to the tension adjustment mechanism 6. The substrate passes through the flattening roller 3, traction mechanism 4, transition roller 5, tension adjustment mechanism 6 and coating roller 9 set on the frame 1 in sequence before entering the flipping frame 2 and being wound up by the second winding shaft 73. The substrate is wound up cyclically.
