[0026] The following specific embodiments illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0027] Please refer to Figure 1 , the present utility model provides a coil uncoiler, including:

[0028] Support frame 1, the support frame 1 includes: a base 4 placed on the ground; a gantry frame 5 fixed to the base 4; and a lifting plate 6 slidably assembled to the gantry frame 5 in the vertical direction. A linear module for driving the lifting plate 6 to slide in the vertical direction so that the lifting plate 6 can complete the descending and lifting actions is installed on the gantry frame 5.

[0029] Please refer to Figure 1, further comprising two sets of support arms 2 that are driven by independent drive sources and are slidably assembled on the lifting plate 6 in the horizontal direction. In this embodiment, the drive source is set as a lead screw mechanism, and in other embodiments, an electric cylinder or a linear module can also be used instead. One end of the support arm 2 away from the lifting plate 6 is rotatably connected to an air shaft 3 through a bearing. The air shaft 3 is connected to an external air supply device. The air shafts 3 on the two sets of support arms 2 are arranged oppositely to insert the two air shafts 3 into both ends of the coil material from both sides respectively during the sliding process of the support arms 2 driven, so as to support the coil material.

[0030] Please refer to Figure 1 , a rotary drive member 7 for driving the air shaft 3 to rotate to achieve continuous material feeding is installed on the support arm 2. In this embodiment, the rotary drive member 7 is set as a servo motor. The output shaft of the servo motor is in gear transmission with the air shaft 3. The servo motor drives the air shaft 3 to rotate stably, and then realizes the stable material feeding of the coil material. In other embodiments, the rotary drive member 7 can also be replaced by a stepping motor.

[0031] Please refer to Figure 1 and Figure 2 , a positioning plate 8 for abutting against the end of the coil material to limit the position of the end of the coil material is fixed on the support arm 2. The positioning plate 8 is used to limit the position of the coil material, so that the coil material cannot shift laterally and the stability is improved.

[0032] When installing the coil material of the present utility model, the linear module drives the lifting plate 6 to descend to a height suitable for the openings on both sides of the coil material. Specifically, the staying position of the lifting plate 6 can be set according to the radius length of the coil material. Then, the drive source drives the two sets of support arms 2 to move away and open the two sets of support arms 2 to the maximum distance. After placing the coil material on the moving paths of the two air shafts 3, the drive source drives the two sets of support arms 2 to close. During the closing process, the two air shafts 3 are inserted into both ends of the coil material respectively. After the air shafts 3 are opened, they can support the coil material. Then, the linear module drives the lifting plate 6 to lift, so that the coil material reaches the predetermined working height. The distance between the two sets of support arms 2 in this solution can be flexibly adjusted according to the width of the coil material, so as to meet the installation requirements of coils with different widths; at the same time, after the coil material is installed in this solution, the position of the coil material can be adjusted by synchronously sliding the two sets of support arms 2 towards the same side, which is more flexible in use.

[0033] The above embodiments only illustrate the principles and effects of the present utility model by way of example, and are not used to limit the present utility model.
