[0016] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0017] The utility model provides a cloth unwinding tension regulating structure which is easy to operate and adjust and is applied in a tension regulating mechanism of a coating machine.

[0018] Please refer to Figure 1 to Figure 2 As shown, the utility model is an easy-to-operate and adjustable cloth unwinding tension adjustment structure, comprising:

[0019] The frame 1 is provided with an unwinding roller 11, a front guide roller 12 and a rear guide roller 13;

[0020] The turntable 2 is connected to the frame 1 through a worm gear mechanism 21. Two support rollers 22 are evenly distributed on the turntable 2 along the circumferential direction. The support rollers 22, the unwinding roller 11, the front guide roller 12 and the rear guide roller 13 are parallel to each other. The cloth unwound by the unwinding roller 11 passes through the front guide roller 12, the support roller 22 and the rear guide roller 13 in sequence.

[0021] From the above description, it can be seen that the beneficial effects of the utility model are: an easy-to-operate and adjustable fabric unwinding tension adjustment structure, after the unwinding roller 11 on the frame 1 unwinds the fabric, the fabric is guided by the front guide roller 12 and the tension control of the support roller 22 and then transported to the rear guide roller 13, and the tension control method is to rotate the worm gear mechanism 21 to drive the turntable 2 to rotate, and when the turntable 2 rotates, the two support rollers 22 rotate accordingly, and when the fabric passes through the two support rollers 22 in turn, it is bent in opposite directions by the two support rollers 22, thereby changing the tension of the fabric. The easy-to-operate and adjustable fabric unwinding tension adjustment structure provided by the utility model reduces the difficulty of tension adjustment operation while ensuring the accuracy of tension adjustment, improves the efficiency of tension adjustment, and is conducive to saving manpower and improving production capacity.

[0022] In an optional embodiment, the frame 1 is provided with an unwinding motor 14 , and the unwinding motor 14 is connected to the unwinding roller 11 .

[0023] From the above description, it can be seen that the unwinding motor 14 is used to assist in controlling the unwinding of the cloth and improve the tension control accuracy.

[0024] In an optional embodiment, the frame 1 is provided with a guide rail 15 , the guide rail 15 is perpendicular to the unwinding roller 11 , a slidable mounting seat 16 is provided on the guide rail 15 , and the turntable 2 is connected to the mounting seat 16 via a worm gear mechanism 21 .

[0025] It can be seen from the above description that the mounting seat 16 can slide on the guide rail 15, thereby changing the position of the tension control component and improving the tension control accuracy.

[0026] In an optional embodiment, the turntable 2 is coaxially connected to the worm wheel of the worm gear mechanism 21 , and the worm of the worm gear mechanism 21 is provided with a handwheel 23 .

The support rollers 22, the unwinding roller 11, the front guide roller 12 and the rear guide roller 13 are parallel to each other. The cloth unwound by the unwinding roller 11 passes through the front guide roller 12, the support roller 22 and the rear guide roller 13 in sequence.

[0033] The frame 1 is provided with an unwinding motor 14, and the unwinding motor 14 is connected to the unwinding roller 11. The frame 1 is provided with a guide rail 15, and the guide rail 15 is perpendicular to the unwinding roller 11. The guide rail 15 is provided with a slidable mounting seat 16, and the turntable 2 is connected to the mounting seat 16 through a worm gear mechanism 21.

The frame 1 is provided with a heating plate 17, and the cloth unwound by the unwinding roller 11 passes through the heating plate 17, the front guide roller 12, the support roller 22 and the rear guide roller 13 in sequence.

[0034] In summary, the utility model has an easy-to-operate and adjustable cloth unwinding tension adjustment structure. After the unwinding roller on the frame unwinds the cloth, the cloth is guided by the front guide roller and the tension of the support roller is controlled before being transported to the rear guide roller. The tension control method is to rotate the worm gear mechanism to drive the turntable to rotate. When the turntable rotates, the two support rollers rotate accordingly. When the cloth passes through the two support rollers in turn, it is bent in opposite directions by the two support rollers, thereby changing the tension of the cloth. The easy-to-operate and adjustable cloth unwinding tension adjustment structure provided by the utility model reduces the difficulty of tension adjustment operation while ensuring the accuracy of tension adjustment, improves the efficiency of tension adjustment, and is conducive to saving manpower and improving production capacity.
