[0031] In this embodiment, preferably, the moving component 21 includes a second threaded sleeve 2101, a vertical rod 2102 and a support rod 2103.

[0033] During use, the staff first controls the push rod 805 to contract through the electric push rod 804 of the feeding component 8 and stores it in the sliding frame 801 to prevent the push rod 805 from protruding from the sliding frame 801. Then, the wide-width galvanized sheet is placed between the two angle irons 19 of the bed body 1, and the push rod 805 will not hinder the feeding activity of the galvanized sheet. Then, the motor two 14 drives the main shaft 12, and the main shaft 12 drives the two worm wheels 16 to rotate synchronously through the two worm gears 13. The two worm wheels 16 convert the rotational motion into the linear motion of the vertical rod 2102 through the second threaded sleeve 2101 of the moving component 21, so as to synchronously adjust the distance between the two angle irons 19. The angle iron 19 can limit the galvanized sheet with different widths through the limiting rollers 20;

[0034] After the two sides of the galvanized sheet are limited, the staff drives the push rod 805 to rise through the electric push rod 804, making its top protrude from the bed body 1. Then, the motor one 6 drives the lead screw 5, and the lead screw 5 converts the rotational motion into the linear motion of the sliding frame 801 through the first threaded sleeve 802. The slideway 3 guides the sliding frame 801, and the sliding frame 801 pushes the galvanized sheet to move horizontally through the push rod 805, so as to feed it. During the feeding process, the moving component 21 can provide stable support for the two angle irons 19. The angle iron 19 increases the support area on both sides of the galvanized sheet through a plurality of limiting rollers 20, which can improve the stability of the galvanized sheet. When the galvanized sheet contacts the limiting rollers 20, the limiting rollers 20 can rotate, which can reduce the friction on both sides of the galvanized sheet;

[0035] When the wide-width galvanized sheet is subjected to a horizontal thrust in a direction different from the feeding direction, the worm 13, the worm wheel 16 and the bidirectional screw 17 can realize the self-locking of the moving component 21, which can prevent the motor two 14 from being stressed. The angle iron 19 and the limiting rollers 20 are not easy to loosen, which can improve the positioning effect of the galvanized sheet and can prevent it from tilting under stress. At the same time, the reliability of the angle iron 19 and the limiting rollers 20 can be ensured. After the galvanized sheet reaches the servo shearing machine 4, the servo shearing machine 4 can perform shearing activities on it.

[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
