Specific embodiments

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-3 , the present utility model provides a technical solution: a feeding mechanism, including a bottom plate 1, a support frame 2 and a lifting motor 3. Pulley 4 is installed at the bottom of the bottom plate 1. The support frame 2 is vertically fixed on one side of the bottom plate 1. A lifting motor 3 is fixedly installed at the top end of the support frame 2 through a support platform frame 5. A handrail frame 6 is fixedly installed on the back of the bottom plate 1. A longitudinal chute 7 is provided on the support frame 2. The bottom end of the lifting motor 3 is connected to a fixed back plate 8 through a motor telescopic shaft. A coil bracket 9 is fixedly installed at the end of the fixed back plate 8;

[0020] The material roll holder 9 is a "匸"-shaped structure, and the opposite surfaces of the left and right side panels of the material roll holder 9 are set as arc surfaces. An electric push rod 10 is fixedly installed on the back of the material roll holder 9, and the electric push rod 10 is respectively located on the left and right sides of the fixed back plate 8. The telescopic rod end of the electric push rod 10 is connected to a limited baffle 11 along the axial direction of the side panel of the material roll holder 9 and penetrates the side panel. A door beam frame 12 is installed on the limit baffle 11, and a stop plate 14 is rotatably installed at the center of the door beam frame 12 by rotating a screw 13.

[0021] The left and right side plates of the material coil bracket 9 and the longitudinal slide groove 7 are slidably connected through a slider 15, which is used to enhance the stability of the material coil bracket 9 during the up and down lifting process.

[0022] A coil workpiece 16 is placed on the coil bracket 9 , and the coil workpiece is supported by the coil bracket 9 .

[0023] The lifting motor 3 drives the fixed back plate 8 and the material roll bracket 9 to perform lifting and displacement movements along the longitudinal slide groove 7 of the support frame 2 through the motor telescopic shaft, which is used for the up and down lifting movement of the material roll workpiece during the feeding process, making it convenient to feed the material roll to different upper and lower heights.

[0024] The door beam frame 12 and the limit baffle 11 are detachably embedded and fixed by bolts. The height of the door beam frame 12 is adapted according to the height of the coil workpiece, so that the stop plate 14 installed on the door beam frame 12 can limit and block the side of the coil workpiece.

[0025] Working principle:

[0026] In this scheme, the entire device is used for feeding material rolls or disc-shaped workpieces. During the feeding process, the material rolls and disc-shaped workpieces are inconvenient to be manually transported and fed due to their large size, which affects the efficiency of material roll feeding and unloading.

[0027] First, the lifting motor 3 works, and the motor telescopic shaft of the lifting motor 3 drives the fixed back plate 8 and the material roll bracket 9 to move downward until the material roll bracket 9 moves to the bottom plate 1, and then the material roll workpiece or the disc-shaped workpiece is manually rolled onto the material roll bracket 9, so that the bottom of the material roll or the disc-shaped workpiece is supported by the left and right side plates of the material roll bracket 9. The left and right side plates of the material roll bracket 9 have an arc-shaped surface structure facing each other, which makes it more convenient for the material roll or the disc-shaped workpiece to enter and exit the material roll bracket 9;

[0028] Next, according to the width of the coil workpiece, the two electric push rods 10 work simultaneously. The end parts of the electric telescopic shafts of the electric push rods 10 drive the limit baffles 11 to be pushed forward from the inside of the left and right side plates of the coil bracket 9, so as to adapt to coil workpieces of different widths. Then, according to the height of the coil workpiece, the gantry frame 12 corresponding to the height is selected, and the rotating screw 13 is manually rotated. The bottom end of the rotating screw 13 is rotatably connected to the abutting plate 14, and the rotating screw 13 and the gantry frame 12 are in threaded rotational connection. When the rotating screw 13 rotates, the abutting plate 14 at the bottom end is displaced downward from the gantry frame 12, so that the bottom plate 14 blocks the coil workpiece from the side, thereby enabling the coil workpiece to be stably supported on the coil bracket 9. Again, the lifting motor 3 drives the fixed back plate 8 and the coil bracket 9 to be lifted upward. During the up and down movement of the coil bracket 9, it is slidably connected to the longitudinal chute 7 on the support frame 2 through the slider 15 to maintain a stable effect. It can be pushed manually by holding the handrail frame 6 on the back of the bottom plate 1. After the coil is fed to the corresponding position, the gantry frame 12 is manually disassembled from the limit baffle 11, and then the coil located on the coil bracket 9 is pushed out by external machinery or manual force.

[0029] 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 principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
