DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Reference Figure 1-3 The top of the plurality of first electric telescopic rods 4 are rotatably connected to the tension roller 5, and the top of the plurality of first electric telescopic rods 4 are rotatably connected to the tension roller 5. The top of the plurality of first electric telescopic rods 4 are rotatably connected to the tension roller 5. The top surface of the base 1 is away from the side of the mounting seat 2 and is rotatably connected to the winding roller 6. The top surface of the base 1 is fixedly installed with a gantry 7. The two inner sides of the gantry 7 are rotatably connected to two second guide rollers 19, and the two second guide rollers 19 are distributed up and down. Two screw sleeves 13 are symmetrically slidably connected to the gantry 7. The gantry 7 drives the two screw sleeves 13 to slide symmetrically through the driving mechanism. One of the second guide rollers 19 is connected to the driving mechanism through a gear transmission mechanism. Each screw sleeve 13 is slidably connected to a smoothing plate 14. A height adjustment structure is provided on the outer side of the gantry 7, and the height adjustment mechanism is connected to each smoothing plate 14.

[0023] It is worth noting that the winding roller 6 is driven to rotate by an external driving device.

[0024] like Figure 1-3 As shown, the specific implementation method is as follows: by arranging the first guide roller 3 and the second guide roller 19, the fabric can pass between the first guide roller 3 and the second guide roller 19, thereby ensuring the height of both sides of the fabric, and at the same time, through the first electric telescopic rod 4 and the tension roller 5, the tension roller 5 can lift the fabric, thereby tensioning the fabric, and at the same time, through the driving mechanism and the gear transmission mechanism, the smoothing plate 14 can reciprocally smooth the fabric, and at the same time, through the height adjustment mechanism, the smoothing plate 14 is made to resist the fabric when it slides outward, and when the smoothing plate 14 slides inward, the height adjustment mechanism is used to raise the smoothing plate 14 to avoid contact with the fabric.

[0025] The driving mechanism includes a double-headed reciprocating screw 17, and the two ends of the double-headed reciprocating screw 17 are respectively rotatably connected to the two inner sides of the gantry 7, and the two screw sleeves 13 are symmetrically threaded on the double-headed reciprocating screw 17. A slide groove 18 is provided on the outer side of the gantry 7, and each screw sleeve 13 is slidably connected to the slide groove 18. The rotation of the double-headed reciprocating screw 17 drives the two screw sleeves 13 to slide symmetrically, and at the same time, the screw sleeves 13 are limited by the slide groove 18 so that they cannot rotate and can only slide linearly.

[0026] The gear transmission mechanism includes a driven gear 16, and the driven gear 16 is installed at one end of the double-headed reciprocating screw 17. One end of the second guide roller 19 located above passes through one side of the gantry 7 and is installed with a driving gear 15, and the driving gear 15 is engaged with the driven gear 16. It is worth noting that when the tension roller 5 drives the fabric to lift, the fabric is abutted against the second guide roller 19 above, so that the second guide roller 19 can be driven to rotate by the movement of the fabric.

[0027] The height adjustment mechanism includes a fixed plate 8, and the fixed plate 8 is fixedly installed on the outside of the gantry 7. A second electric telescopic rod 9 is fixedly installed on the top surface of the fixed plate 8, and an assembly seat 10 is fixedly installed on the top of the second electric telescopic rod 9. Automatic telescopic rods 11 are fixedly installed on both outsides of the assembly seat 10, and the other end of each automatic telescopic rod 11 is fixedly installed with a sliding column 12, and each sliding column 12 is slidably connected to the corresponding position of the screw sleeve 13, and each smoothing plate 14 is fixedly installed on the bottom end of the sliding column 12. It is worth noting that the assembly seat 10 is driven to slide up and down by the second electric telescopic rod 9, and the connection of the automatic telescopic rod 11 can drive the sliding column 12 to slide up and down synchronously.

[0028] The pitch circle diameter length of the driving gear 15 is greater than the pitch circle diameter length of the driven gear 16 , so that the driven gear 16 can rotate quickly, thereby increasing the reciprocating sliding frequency of the smoothing plate 14 .

[0029] The outer side of each comforting plate 14 is arranged in an arc shape, and each first electric telescopic rod 4 is arranged between the mounting seat 2 and the gantry 7.

[0030] When the utility model is used, the fabric is first passed between the two first guide rollers 3, and the fabric passes over the tension roller 5, then passes between the two second guide rollers 19, and is wound on the winding roller 6, and then the winding roller 6 is driven to rotate by an external driving device, thereby driving the fabric to move, and at the same time, the tension roller 5 can be driven to rise in height by starting the two first electric telescopic rods 4, thereby driving the fabric to rise, so as to adjust the tension of the fabric, and at the same time, after the fabric is tensioned, the fabric is against the second guide roller 19 above, thereby driving the second guide roller 19 to rotate, and the driving gear 15 and the second guide roller 19 are connected. With the cooperation of the moving gear 16, the double-headed reciprocating screw 17 is driven to rotate. Due to the cooperation of the slide groove 18, the two screw sleeves 13 can be driven to slide back and forth. At the same time, when the screw sleeve 13 drives the smoothing plate 14 to slide outward, the second electric telescopic rod 9 can be started to retract, and the smoothing plate 14 is driven to move downward through the assembly seat 10 and the automatic telescopic rod 11, so that the fabric is smoothed by the smoothing plate 14. At the same time, when the smoothing plate 14 slides inward, the smoothing plate 14 is lifted by the second electric telescopic rod 9, thereby avoiding contact between the smoothing plate 14 and the fabric, thereby realizing reciprocating smoothing of the fabric and reducing the curling of the fabric edge.

[0031] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
