A guide groove 6 for the first mandrel 2 to move in the height direction is provided on the device main body 1. A pair of second hydraulic cylinders 7 for lifting the height of the first mandrel 2 are provided in the device main body 1. The output shaft of the second hydraulic cylinder 7 is fixedly connected to the first mandrel 2 through a bushing. The pair of second mandrels 3 are fixedly connected to the device main body 1. The first mandrel 2 and the pair of second mandrels 3 are arranged in a triangular shape. A slide rail 8 is provided on one side of the device main body 1. A feeding assembly is provided on the slide rail 8 and the feeding assembly is fixedly connected to the output shaft of the first hydraulic cylinder 4. A driving assembly for driving the rotation of the steel belt 12 is further provided on the feeding assembly.

[0016] A guiding groove 6 is provided on the device main body 1, and the first mandrel 2 is lifted by a second hydraulic cylinder 7 so that the material taking device can be adapted to steel belts 12 with different apertures for installation. The second mandrel 3 is used to support the weight of the steel belt 12, and the first mandrel 2 is used to adjust the tension so that the steel belt 12 installed on the mandrel can be stable. In practical applications, the steel belt 12 is transported to the feeding assembly by a crane. The feeding assembly drives the steel belt 12 to be placed on the paired second mandrels 3 through a first hydraulic cylinder 4, and the steel belt 12 is tensioned by adjusting the height position of the first mandrel 2. Finally, the driving assembly on the feeding assembly drives the steel belt 12 to take materials.

[0017] The feeding assembly includes a base 9 installed on a slide rail 8, a lifting platform 10 installed on the base 9, a storage seat 11 installed on the lifting platform 10, and a laser distance sensor installed at the central position of the storage seat 11. The base 9 is fixedly connected to the output shaft of the first hydraulic cylinder 4 to drive the base 9 to move on the slide rail 8. The driving assembly is arranged on the storage seat 11, and the driving assembly lifts the height through the lifting platform 10 to abut against the bottom of the steel belt 12 and drive the steel belt 12 to rotate. The lifting platform 10 is provided to adjust the height of the storage seat 11, so as to facilitate the abutment of the driving assembly with the steel belt 12 and the preliminary installation of the steel belt 12 on the second mandrel 3.
