Description

Technical Field

[0001] The utility model relates to the technical field of uncoiler processing equipment, in particular to a positioning mechanism for an uncoiler. Background Art

[0002] An uncoiler is a device dedicated to leveling metal sheets. The main function of the uncoiler is to lead out the leading end, level it and feed it into the rolling mill, and at the same time provide sufficient uncoiling tension during rolling. Its main functions include rotating the coil material, fixing the coil material, loading and unloading the coil material, etc. When the uncoiler is working, first, an inner support cylinder is sleeved outside the supporting tile plate of the uncoiler, and then the supporting tile plate is controlled to rotate to wind up the strip steel. In order to ensure the stability and regularity of the strip steel during winding, generally, according to the width of the strip steel, a triangular baffle plate (also called A-shaped plate) is installed at the corresponding position of the supporting tile plate. The baffle plate can limit the position of the strip steel during winding, so as to ensure that the strip steel is wound neatly together. At present, when the baffle plate is installed, its bottom plate is directly fixed to the supporting tile plate through bolts. When assembling in this way, in order to strengthen the connection, tools such as wrenches and pliers are needed for assistance. Due to the limited installation space, it is very inconvenient for workers to install the baffle plate. Summary of the Utility Model

[0005] Furthermore, the detachable lock pin includes a pin rod. Pin holes that communicate with each other are provided on the bottom plates of the material supporting tile plate and the material retaining plate. The pin rod is inserted into the pin holes. An annular edge is provided on the part of the pin rod located inside the mounting cylinder base. The diameter of the annular edge is adapted to the inner diameter of the mounting cylinder base.

[0023] The detachable locking pin includes a pin rod 7, pin holes 13 communicating with each other are arranged on the bottom plate 5a of the material supporting tile plate 4 and the material blocking plate 5, the pin rod 7 is inserted into the pin holes 13, an annular edge 8 is arranged on the part of the pin rod 7 located in the mounting cylinder seat 6, the diameter of the annular edge 8 is adapted to the inner diameter of the mounting cylinder seat 6, a telescopic spring 9 is further arranged on the part of the pin rod 7 above the annular edge 8, the upper end of the telescopic spring 9 abuts against the bottom of the material supporting tile plate 4, the lower end of the telescopic spring 9 abuts against the upper end of the annular edge 8, a plurality of positioning protrusions 10 are arranged circumferentially at one end of the pin rod 7 passing through the bottom plate 5a upward, and a plurality of chutes 11 adapted to the positioning protrusions 10 are evenly arranged on the material supporting tile plate 4 and the bottom plate 5a in the circumferential position along the pin holes 13, and the chutes 11 in the same vertical direction on the material supporting tile plate 4 and the bottom plate 5a communicate with each other to form a slideway convenient for the positioning protrusions 10 to slide up and down.

[0024] At the top of the bottom plate 5a, several positioning grooves 14 adapted to the positioning protrusions 10 are also provided at positions circumferentially along the pin holes 13, and the positioning grooves 14 are arranged in a staggered manner with the sliding grooves 11 on the bottom plate 5a.

[0025] One end of the pin rod 7 penetrates downward through the bottom wall of the mounting cylinder base 6 and is provided with a rod head 15.

[0026] At the two end corners of the lower end of the material baffle 5, plug connectors 5b are provided, and slots adapted to the ends of the material supporting tile plates 4 are provided on the plug connectors 5b. The two ends of the material supporting tile plates 4 are respectively inserted into the slots of the plug connectors 5b.
