Uncoiler comprises the material roller of a place work piece, workpiece is generally the reel pattern of rolling and is set on material roller, one end connecting axle of material roller turns driving mechanism, uncoiler material roller is by being with gradient dovetail groove to connect four fanning strips on four end faces, every fanning strip tail end by one radially slideway prevent its axial float, but can realize radially harmomegathus.At spool shaft material roller tail end, be connected with rotary oil cylinder, cylinder piston rod drives front end four rib axles to endwisely slip by the pull bar at spool shaft center, thereby drives radially harmomegathus of fanning strip, and can increase nominal diameter by four additional fanning strips.Uncoiler frame can move on the guide rail of support, by hydraulic cylinder, is driven, and can realize center and control.For strengthening the stability of reel, in material roller head design, there is support arm device, while having coil of strip on material roller, support arm, by hydraulic oil cylinder driving, is held material roller head, and support arm is retracted at ordinary times, can not affect rolling steel coil.Though this device can have to a certain extent expand fixing effect because four fanning strips are that mode by radially folding completes, so external support force is stressed minimum, needs very large motive force just can complete spreading.
Summary of the invention
The purpose of this utility model is the problems referred to above that exist for existing uncoiler, and has proposed a kind of circumferentially spacing closelyr, and stability is stronger, the material roller of the uncoiler of spreading better effects if.
The purpose of this utility model can realize by following technical proposal: a kind of material roller of uncoiler, it is characterized in that, it comprises that multi-disc circumferentially encloses pillared expansion piece, the tail end of expansion piece is provided with accepts circle, the middle part of material roller is provided with the expansion ejector sleeve that two ends differ in size vertically, the outer surface of expansion ejector sleeve and the laminating of the inner surface of expansion piece, and be connected with hydraulic cylinder on this expansion ejector sleeve, by hydraulic cylinder, pull the front and back position of expansion ejector sleeve to change the nominal diameter of expansion piece, the lateral surface of expansion piece is provided with flat key, flat key is axial towards establishing along material roller, flitch is wound on reel, described drum sheath is located at and on material roller and in inner side, offers the keyway coordinating with flat key.
Support that expansion piece is swollen can not rocked reel, and flat key can limit relatively rotating of sleeve, and the big or small two ends of expansion ejector sleeve are along pipe to evenly excessive.
In the material roller of above-mentioned a kind of uncoiler, on described every expansion piece, be equipped with flat key.
In the material roller of above-mentioned a kind of uncoiler, the outer surface of described expansion ejector sleeve and the inner surface of expansion piece are respectively equipped with projection and the groove of the screens that cooperatively interacts, and projection and groove arrange vertically.
Compared with prior art, this device form by expansion piece changes nominal diameter, the power in the time of can reducing to promote and reach identical effect, and the circumferential rotation of the spacing reel of flat key, has reinforced relatively rotating of reel and material roller.
