During installation, the bolts penetrate through the second waist-shaped holes from the outer side faces of the side plates 13 and are connected with the threaded holes in the limiting plates 16, and therefore the limiting plates 16 are fixed. In use, when a material is lifted away, the subsequent material is guided by the upper surface of the bottom plate 11 to move forward and stay on the opening formed between the front plate 12 and the bottom plate 11.

When in use, the top block 22 ejects the raw material out of the material storage cavity 15, the raw material rolls down onto the material transporting bin 32 under the guiding action of the guiding surface of the top block 22, and then the raw material continues to roll down under the action of the inclined surface of the material transporting bin 32 and finally abuts against the rear end surface of the elastic piece 333. Subsequently, the linear motor module operates to move the slide block thereon, so as to drive the sealing assembly 33, the material transporting bin 32 and the raw materials to move. When the transportation bin 32 reaches a designated position, the linear motor module stops operating, so that the transportation bin 32 stops moving. At this time, the sealing cylinder 331 operates such that the moving end thereof moves to drive the baffle 332 and the elastic member 333 to move upward for a certain distance, and thus, the raw material on the material transporting bin 32 can fall to a designated position through the gap between the elastic member 333 and the raw material.

In use, the driving cylinder 21 is operated, so that the jacking block 22 moves vertically upwards and jacks up the raw material in the storage assembly 10. Then, the raw material falls into the material transporting bin 32, rolls downward under the action of the inclined surface of the material transporting bin 32, and finally abuts against the rear end surface of the elastic member 333. The slider of linear electric motor module will seal subassembly 33 and fortune feed bin 32 and take to the casing in to stop in the top of card material device, at this moment, seal subassembly 33 work, its removal end removes, thereby drives baffle 332 and elastic component 333 rebound, so, the raw materials just can fall into on the card material device through the clearance between elastic component 333 and the fortune feed bin 32. Finally, the material clamping device conveys the raw material to a chuck of the main body, so that the raw material is machined by a numerical control lathe (not shown). So, realized automatic feeding, and because storage component 10 installs in the outside of casing, so, can place the raw materials in numerical control lathe's outside, and need not to open numerical control lathe's emergency exit, when reducing labour's consumption, practiced thrift a large amount of process time to production efficiency has been improved.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
