In the production process of photovoltaic modules, a tape unwinder is needed to unwind the rolled EVA film to provide a continuous and stable material supply for docking equipment for subsequent processing. The operation of the unwinder can realize the automatic unwinding of the material, thereby improving production efficiency and reducing the labor intensity of manual operation.

[0067] Specifically, the bracket 1 is used to provide stable support for the drive unit 2, follower roller group 3 and other components of the unwinding machine. The bracket 1 may include a crossbeam 101 and two side panels 102. The crossbeam 101 is located between the two side panels 102 and is clamped or welded to the two side panels 102 respectively. The crossbeam 101 may be close to the bottom surface of the side panels 102 at both ends to avoid other components.

[0068] The driving unit 2 is used to provide power to drive the coil 12 to rotate around the first horizontal direction A to achieve the unwinding action. The driving unit 2 can be located on the first side of the follower roller group 3 along the second horizontal direction B. The driving unit 2 can be connected to the bracket 1 by bolts or clamping to ensure the stability and reliability of the driving unit 2. The driving unit 2 can be connected to the core shaft of the coil 12 by a flange or a coupling to achieve effective force transmission. The driving unit 2 can be an electric motor or a hydraulic motor.

[0069] The follower roller group 3 is used to ensure that the coil 12 moves smoothly during the unwinding process and ensure the stability of the raw material. The follower roller group 3 is away from the support surface where the bracket 1 is located relative to the coil 12. The follower roller group 3 may include multiple rollers, and the multiple rollers may be arranged in parallel and at intervals along the second horizontal direction B.

The swing assembly 4 is located at a position close to the second side of the follower roller group 3 along the second horizontal direction B. The swing assembly 4 is close to the support surface where the bracket 1 is located relative to the follower roller group 3. The swing assembly 4 may include a first shaft, a second shaft, a third shaft and two connecting rods. The first shaft and the second shaft may be arranged at intervals along the first horizontal direction A. The axis of the first shaft and the axis of the second shaft may coincide.

The connection groove or the connection hole can be strip-shaped, and its length direction can be consistent with the direction of the cutter 7, so as to achieve more uniform and comprehensive heating of the cutter 7. The heating component can be an electric heating wire or a heating rod, etc. The heating component is electrically connected to a power source to achieve heating.

[0099] When it is necessary to cut the raw material, the driving unit 2 can be stopped to suspend the unwinding, and then the first lifting mechanism 6 can accurately control the lifting of the cutter 7, and cooperate with the top plate 103, so that it can quickly and accurately contact the raw material for cutting operations, without the need to manually adjust the height of the cutter 7, which greatly improves the convenience and efficiency of the operation. Since the heating component heats the cutter 7, the heated cutter 7 can cut the raw material, such as EVA film or rubber, more smoothly during the cutting process, which can effectively reduce burrs and tearing at the incision, making the incision more neat and beautiful, and improving the quality of the product. When not in use, the first lifting mechanism 6 can lift the cutter 7 to ensure normal unwinding.

The driving member 81 may be connected to the top plate 103 by bolts or clamping. A through hole may be provided on the top plate 103 in the vertical direction. The driving end of the driving member 81 may pass through the through hole and be riveted or bolted to the pressure strip 82. The pressure strip 82 is arranged at intervals with the cutter 7, and the length direction of the pressure strip 82 may be consistent with the first horizontal direction A. In order to ensure the stability of the drive, there may be two driving members 81, and the two driving members 81 are arranged at intervals along the second horizontal direction B, and the two driving members 81 are respectively connected to the two ends of the pressure strip 82. The raw material can pass between the pressure strip 82 and the top plate 103, and the driving member 81 is used to drive the pressure strip 82 to move in the vertical direction close to the raw material to achieve the compression of the raw material. The driving member 81 may be a linear motor or a hydraulic cylinder.

[0103] There may be one or two clamping mechanisms 8. When there are two clamping mechanisms 8, the two clamping mechanisms 8 may be respectively located on both sides of the cutter 7 along the first horizontal direction A. When cutting is required, the clamping mechanism 8 may first press the raw material on the top plate 103, and then the cutter 7 is lowered under the control of the first lifting mechanism 6 for cutting, so that the cutter 7 can act on the raw material more stably during cutting, thereby improving the stability and reliability of cutting.

The second driving mechanism can be a linear motor or a hydraulic cylinder, etc.

[0112] When rolling up, the second lifting mechanism 92 can lower the carrier 93 to a suitable height, so that the operator can place the coil 12 on the carrier 93. After the rolling up is completed, the second lifting mechanism 92 can lift the coil 12 to the working height, and then lock and position it through the blocking member 94 and the abutting bolt 95 to ensure the stability of the installation and improve the efficiency and safety of the rolling up.

[0113] like Figure 1 and Figure 2 As shown, in some embodiments, it also includes:

[0118] Example 2

[0119] Embodiment 2 of the present application provides a method for controlling the unwinding speed of a tape unwinding machine, which is used for the tape unwinding machine of embodiment 1, such as Figures 1 to 3 As shown, including:

[0120] The raw material after unwinding the coil 12 and flattening it is in close contact with the swing component 4; wherein the raw material can drive the swing component 4 to swing during the movement;

[0121] Measuring the swing angle of the swing component 4;

[0122] The unwinding speed of the web 12 is controlled based on the swing angle.

[0123] Specifically, the unwinding machine is started, and the coil 12 begins to unwind. The unwound raw material can be manually brought into close contact with the follower roller group 3 and the swing assembly 4, and docked with the docking device. The angle sensor 5 measures the swing angle of the swing assembly 4. When the angle measured by the angle sensor 5 is 0, that is, when there is no swing, the drive unit 2 maintains the current unwinding speed; when the angle measured by the angle sensor 5 is not 0, that is, the swing assembly 4 swings, the angle sensor 5 converts the measured angle information into a first signal, and the drive unit 2 obtains the first signal and controls the unwinding speed of the coil 12 based on the first signal, so that the unwinding speed can be consistent with the docking speed of the docking device, so that the tension of the raw material is maintained within a suitable range, and the stability and reliability of the unwinding process are ensured.

[0124] The unwinding speed control method of the unwinding machine of Example 2 of the present application realizes the tensioning of the raw material due to the close contact between the raw material and the swing component 4, thereby ensuring the stability of the raw material during the unwinding process; when the unwinding speed and the docking speed are inconsistent, the tension of the raw material will change, and this change will cause the swing component 4 to swing. By measuring the swing angle of the swing component 4, the unwinding speed of the coil 12 can be controlled in real time to match the docking speed, effectively solving the problems of material stretching, deformation or breakage caused by unstable tension, and significantly improving the quality of the material in subsequent processing steps.
