DETAILED DESCRIPTION

[0017] The technical solution of the present invention will be further specifically described below with reference to embodiments and in conjunction with the accompanying drawings.

[0018] Example: Figure 1 、 Figure 2 and Figure 3As shown, a blowing mechanism for eliminating fabric roll tension comprises a pair of wall panel frames 1, with a pair of protective doors 10 provided on the outside of the wall panel frames 1 and fixedly connected to the wall panel frames 1 in a hinged manner. Four connecting crossbars 7 are provided between the lower portions of the wall panel frames 1, connecting to the wall panel frames 1 to form a frame structure. A blowing plate 4 is provided at the upper end of one side of the wall panel frames 1, with 95 blowing slots 9 arranged in an array. A plurality of air guide ducts 13 are provided at the lower end of the blowing plate 4, connecting to the blowing slots 9 and the wall panel frames 1. Two fans 8 are mounted on the connecting crossbars 7. A bellows 6 connected to the air guide ducts 13 is provided between the fans 8 and the wall panel frames 1. A flow control valve 5 is provided between the bellows 6 and the air guide ducts 13. A spreading roller 3 is located at the upper end of the other side of the wall panel frame 1. A motor 11 is installed on the inner wall of one side of the wall panel frame 1. A driving pulley 14 is installed inside the wall panel frame 1, which is fixed to the motor 11 with a parallel key retaining spring. A driven pulley 15 is installed diagonally above the driving pulley 14, which is fixed to the spreading roller 3 with an insertable bolt connection. Bearing blocks 12 are located between each end of the spreading roller 3 and the inner wall of the wall panel frame 1. These bearing blocks 12 are bolted to the wall panel frame 1. Cloth pressing rollers 2 are installed on the outer sides of the spreading roller 3 and the outer sides of the blowing plate 4, connected to the inner walls of the wall panel frame 1 on both sides. Three cloth pressing rollers 2 are installed between the spreading roller 3 and the blowing plate 4, connected to the inner walls of the wall panel frame 1 on both sides.

[0019] Working Principle: When the operator turns on the power, both fans 8 and motor 11 start simultaneously. During operation, fans 8 blow strong air into bellows 6. After passing through bellows 6, the strong air enters flow control valve 5 and finally enters air guide duct 13, where it is blown out through air holes 9 in air blowing plate 4.

[0020] When the unwinding mechanism sends the cloth to the top of the blowing plate 4, it will be blown by the wind to make an upward undulating motion, similar to the motion when a person shakes the cloth manually, thereby eliminating the tension of the cloth roll. The operator controls the wind force by adjusting the flow control valve 5 to control the amplitude of the shaking of the cloth.

[0021] During the operation of the motor 11, the driving pulley 14 is driven to rotate, the driving pulley 14 drives the belt 16, the belt 16 drives the driven pulley 15 to rotate, and the driven pulley 15 drives the cloth spreading roller 3 to rotate. The cloth spreading roller 3 drives the cloth forward while rotating, and at the same time, with the cooperation of the cloth pressing roller 2, the cloth passing through the blowing plate 4 is flattened to prevent wrinkles.

[0022] In summary, this air blowing mechanism for eliminating cloth roll tension is characterized by a compact structure and good operational stability. As the cloth moves forward with the roller, it is simultaneously blown upward by the wind from the fan, simulating the movement of manually shaking the cloth, thereby eliminating cloth roll tension.

[0023] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the essential characteristics of the present invention.
