[0027] like Figure 1-3 As shown, a box-type bar material automatic feeding device of this embodiment includes a feeding mechanism 1, a feeding box 2, and a pushing mechanism 3. One end of the feeding mechanism 1 is connected to a material tray 4, and the other end is connected to the feeding box 2 at the end. The pushing mechanism 3 is arranged on the side of the feeding box 2;

[0028] The feeding box 2 includes a front side plate 21, a rear side plate 22, a bottom plate 23, a feed valve plate 24 that can rotate in a vertical plane, and a fixed plate 25. The two ends of the feed valve plate 24 and the fixed plate 25 are fixed between the front side plate 21 and the rear side plate 22, and the bottom plate 23 is fixed between the front side plate 21 and the bottom of the rear side plate 22. The feed valve plate 24 includes two movable stations. In station one, the feed valve plate 24 and the fixed plate 25 are set at a distance, and the minimum distance between the two is less than the maximum size of the blank 5. In station two, the minimum distance between the feed valve plate 24 and the fixed plate 25 is greater than the maximum size of the blank 5. The feeding process can be carried out in an orderly manner.

[0029] The feeding mechanism 1 includes a feeding spring 11, a feeding push plate 12, and a feeding cylinder 13 (not shown in the figure); one end of the feeding spring 11 is connected to the feed tray 4, and the other end is connected to the feeding push plate 12, and the feeding push plate 12 is connected to the feeding cylinder 13. The feeding push plate 12 can move horizontally and linearly inside and outside the feeding box 2, driving the blank 5 into the feeding box 2, and then extending out to transport the next blank 5.

[0030] The pushing mechanism 3 comprises a pushing plate 31 and a pushing cylinder 32. The pushing plate 31 is connected to the movable end of the pushing cylinder 32. The pushing plate 31 can be moved horizontally and linearly inside and outside the feeding box 2, and its moving direction is perpendicular to the feeding pushing plate 12. The pushing plate 31 is a rectangular plate structure, and its length is longer than the width of the feeding box, so that the pushing plate can push out the blank 5.

[0031] This embodiment also includes a trough adjustment mechanism 26, which can slide on the fixed plate 25 in a horizontally adjustable manner, and the distance between the trough adjustment mechanism 26 and the front side plate 21 is equal to or greater than the length of the blank 5. The trough adjustment mechanism 26 includes an adjustment nut 261 and a movable plate 262. A groove 2621 is provided at the top of the fixed plate 25. The adjustment nut 261 passes through the movable plate 262 and is stuck in the groove 2621.

[0032] This embodiment also includes a discharging limit plate 27 that can be adjusted up and down. Figure 6 As shown, the discharge limiting plate 27 is arranged on the side of the feeding box 2 and opposite to the pushing mechanism 3. Its function is to prevent the blank from sliding freely. The distance between the bottom surface of the discharge limiting plate 27 and the top surface of the bottom plate 23 is equal to or slightly smaller than the diameter of the blank 5.

[0033] This embodiment also includes a material pressing block 241, which is fixed on the feed valve plate 24 to help the blank to be lowered.

[0034] Specifically, the front side plate 21 is a feed limiting plate, and its function is to allow the blank 5 to enter the feeding box and block the feed push plate 12 outside.

[0035] The working process of the present invention is combined with Figure 4-6 As shown, the blanks 5 do not need to be arranged neatly. When the device feeds, it only needs to ensure that there are blanks 5 in the material tray 4. The feed spring 11 will push the blanks 5 through the feed push plate 12 of the feed box feed port, and the feed cylinder 13 will be used to transport the blanks to the feed box 2 slot. The slot adjustment mechanism 26 can be adjusted arbitrarily according to the length of the blanks. After the blanks 5 enter the box slot, the feed valve plate 24 is actuated. Figure 5 As shown, the pressing block 241 presses the blank 5 into the feeding box 2, and then the feeding push plate 31 pushes the blank 5 into the processing equipment through the gap between the discharge limit plate 27 and the bottom plate.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
