The patent mainly includes a rack, which is sequentially provided with a first guide roller, a tension roller, a pressure roller, a parallel double roller, a second guide roller, and a winding roller according to the movement direction of the fabric. The tension roller is adjustably arranged on the rack through a lifting mechanism to adjust the tension of the fabric. The pressure roller is arranged on the rack through a spring mechanism. A cutting mechanism is arranged below the parallel double roller to cut the fabric. Although the tension of the fabric winding can be adjusted by the tension roller to ensure the quality of the winding, and the pressure roller is movably connected to the rack by a spring to maintain the balance of the fabric tension and has a certain buffering effect.

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figures 1-4This utility model discloses an adjustable tension coated fabric winding device, which includes a U-shaped frame 1. One end of the frame 1 is rotatably connected to a guide roller 2, and the other end of the frame 1 is equipped with a winding roller 3. The winding roller 3 is located on one side near the middle of the frame 1. Two adjusting rollers 6 are installed on the inner side of the frame 1, which are arranged vertically and spaced apart. Two connecting components for fixing the winding roller 3 are symmetrically arranged on the side of the frame 1 near the winding roller 3. The connecting components include two adjacent rotating wheels 11 rotatably connected to one side of the frame 1, and a roller 6 installed on the outer side of the frame 1. An electric push rod 14 is located above the central shaft of the take-up roller 3, a mounting bracket 15 is fixedly connected to the bottom end of the piston rod of the electric push rod 14, and a roller 16 is rotatably connected to the inner side of the mounting bracket 15. The two ends of the central shaft of the take-up roller 3 are respectively attached to each of two adjacent rollers 11. A limit groove 13 is opened on the side of the central shaft of the take-up roller 3 near both ends. The roller 16 is rotatably connected to the inside of the limit groove 13. A second motor 12 is also fixedly connected to the side of the frame 1 near one of the rollers 11. The central shaft of the roller 11 near the second motor 12 is fixedly connected to the output shaft of the second motor 12.

[0025] After the take-up roller 3 to be wound is placed above the rollers 11, the electric push rod 14 moves the roller 16 downward into the limiting groove 13, which helps ensure the stability of the take-up roller 3 during rotation. When the second motor 12 is working, it can drive the take-up roller 3 to rotate and wind up the fabric. After the take-up roller 3 has finished winding, the electric push rod 14 separates the roller 16 from the limiting groove 13, so the take-up roller 3 can be removed for replacement. The operation is convenient, making the replacement of the take-up roller 3 simpler and more efficient, thus helping to improve winding efficiency.

[0026] Inside the frame 1, on one side near the middle, there are two symmetrically rotatably connected shafts 4. Each shaft 4 has a turntable 5 fixedly connected to one of its adjacent ends. Two adjusting rollers 6 are rotatably connected between the turntables 5. On one side of the frame 1 near one of the shafts 4, there is a drive assembly for driving the shaft 4 to rotate. The drive assembly includes a first motor 8 fixedly connected to the outside of the frame 1 and two meshing gears 7. One gear 7 is fixedly connected to the end of the shaft 4, and the other gear 7 is fixedly connected to the output shaft of the first motor 8.

[0027] When the first motor 8 is working, it can drive the rotating shaft 4 and the turntable 5 to rotate through the transmission of the gear 7. The rotating turntable 5 drives the adjusting roller 6 to rotate. The rotating adjusting roller 6 drives the side of the fabric close to the take-up roller 3 to move downward, and at the same time drives the side of the fabric close to the guide roller 2 to move upward, so as to apply pressure to the fabric and adjust the tension of the fabric during the take-up process.

[0028] A bidirectional lead screw 9 is rotatably connected between the turntables 5 and on the side near the top. Two adjusting discs 10 are symmetrically threaded on the outside of the bidirectional lead screw 9. The adjusting discs 10 are slidably connected to the adjusting rollers 6. One end of the bidirectional lead screw 9 passes through the turntable 5 and extends between the frame 1 and the turntable 5. An internal hexagonal groove is opened inside the end of the bidirectional lead screw 9 located between the frame 1 and the turntable 5 so as to use tools for rotation operation.

[0029] By rotating the bidirectional lead screw 9, two adjusting discs 10 can be driven to move towards or away from each other on the bidirectional lead screw 9, thereby driving the adjusting rollers 6 to adjust the distance between them, realizing the limiting operation of fabrics of different sizes, so as to ensure the neatness of the fabric when it is rolled up.

[0030] Working principle: After the take-up roller 3 to be wound is placed above the rollers 11, the electric push rod 14 moves the roller 16 downward into the limiting groove 13, which helps to ensure the stability of the take-up roller 3 when it rotates.

[0031] Arrange the fabric according to Figure 4 As shown in the diagram, when the second motor 12 is working, it can drive the take-up roller 3 to rotate and take up the fabric. When it is necessary to adjust the tension during the winding process, the first motor 8 can drive the rotating shaft 4 and the turntable 5 to rotate through the transmission of the gear 7. The rotating turntable 5 drives the adjusting roller 6 to rotate. The rotating adjusting roller 6 drives the side of the fabric close to the take-up roller 3 to move downward, and at the same time drives the side of the fabric close to the guide roller 2 to move upward, so as to apply pressure to the fabric, so as to adjust the tension of the fabric during the winding process and ensure the quality of winding.

[0032] After the take-up roller 3 completes winding, the roller 16 is separated from the limiting groove 13 by the electric push rod 14, and the take-up roller 3 can be removed for replacement. The operation is convenient, making the replacement of the take-up roller 3 simpler and more efficient, which helps to improve winding efficiency.

[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
