[0016] The utility model will be further explained in connection with the drawings.

[0017] As attached Figs. 1-2 The multiple adaptability anti-deviation unwinding device of the blanking production line, including the rotating drum structure, can be matched with the inner hole of the coiled material 1 and form a supporting force on the inner hole wall of the coiled material 1, a pair of limiting structures 2 are sleeved on the rotating drum structure, and the two limiting structures 2 are respectively attached to the two side end faces of the coiled material 1, the two limiting structures 2 form a side thrust on the coiled material 1, one end of the limiting structure 2 away from the coiled material 1 is fixedly connected with the rotating drum structure, and the other end close to the coiled material 1 is axially slidably connected with the rotating drum structure, the fixed end structure 21 of the two limiting structures 2 is symmetric about the axial center of the rotating drum structure, the fixed end structure 21 and the sliding end structure 22 are connected by an adaptive adjusting structure, and the sliding end structure 22 can slide to the axial length of the two limiting structures 2. That is, the position of the coiled material on the rotating drum structure is restricted by the two side thrust limiting members with adaptive length adjustment, since one end of the limiting structure is fixed and the other end can slide and adjust, the spacing of the two limiting structure members can be adjusted at will, thereby meeting the limiting requirements of coiled materials of different widths, then the axial center position of the fixed end structure relative to the rotating drum structure is symmetrically arranged, and the adaptive length adjustment of the adjusting structure is matched, so that the coiled material can be maintained on the axial center line of the rotating drum structure on the basis of lateral limiting, and bidirectional side thrust is conducive to maintaining the flushness of each layer of the side end face of the coiled material, stabilizing the coiled material structure, ensuring stable and orderly unwinding, and a compression wheel 4 can be arranged above or below the axial center line of the rotating drum structure, depending on whether the coiled material is unwound from the upper side or the lower side, after being restricted and positioned by the two side limiting structures, the compression wheel 4 can press on the unwinding side of the coiled material of any width to avoid the loosening of the outer layer of the coiled material, and the width direction limiting of the two side limiting structures and the radial limiting of the compression wheel can prevent the strip drawn from the coiled material from shifting left and right, achieving the anti-deviation effect, and this effect is achieved when any width coiled material is installed.

[0018] The rotating drum structure includes a plurality of supporting members 3, and the plurality of supporting members 3 are annularly distributed to form an annular discontinuous supporting surface, which is attached to the inner hole wall of the coiled material 1; the plurality of supporting members 3 are connected with a zoom mechanism and can be simultaneously gathered or expanded. The supporting member 3 is a sheet-shaped supporting plate with a circular arc cross section, the outer circular arc surface of which is attached to the inner hole of the coiled material to form a supporting force, and the annular plurality of supporting members form an expansion force on the coiled material, so that the coiled material and the rotating drum structure are relatively tensioned as a whole, thereby enabling the rotating drum structure to have a function of adjustable cylinder diameter when unwinding, so as to meet the sleeving of coiled materials of different inner diameters and form an expansion jacking force on the inner hole to further ensure the stability of the coiled material structure during unwinding, avoid the left and right sliding of the coiled material due to the gap between the coiled material and the rotating drum structure, and effectively achieve the effects of centering, anti-deviation and stable unwinding.

[0019] The scaling mechanism comprises a central sleeve, which is connected to the transverse pull rod through a bearing sleeve, the pull rod is connected with the motor shaft through a screw rod transmission mechanism, and the axial transverse movement of the pull rod is driven by the motor. The central sleeve is connected to the inner side of the support 3 through two rocker arms, and the two rocker arms, the central sleeve and the support form a hinged four-bar mechanism. One end of the central sleeve is also provided with a limiting disc, and radial guide grooves are arranged on the limiting disc corresponding to each support for constraining and supporting the radial sliding movement of the support. When the central sleeve is driven to move axially by the pull rod, the multiple supports can be driven to expand and contract synchronously by the annular multiple hinged screw rod mechanisms. During the expansion and contraction process, each support always maintains a horizontal state, thereby meeting the internal support requirements of the roll material with any inner diameter.

[0020] Based on the above-mentioned adjustable outer diameter rotary drum structure, the limiting structure is correspondingly arranged on the multiple supports. The limiting structure arranged on one support is regarded as one limiting unit. Then the limiting structure on one side of the roll material is composed of multiple limiting units. If the number of supports is even, the multiple limiting units forming the limiting structures on both sides of the roll material can be distributed annularly and equidistantly, and the limiting structures on both sides can be staggered, so that the lateral stress of the roll material is balanced. The limiting unit on a single support is also composed of a fixed end structure 21, a sliding end structure 22 and an adjusting structure. The fixed end structure 21 and the sliding end structure 22 each comprise a sliding block matched with the support 3. The sliding block is provided with a threaded hole. A positioning screw is fitted in the threaded hole of the fixed end structure 21. The positioning screw is in screwing cooperation with a positioning screw hole on the support 3. A locking screw is fitted in the threaded hole of the sliding end structure 22. When the locking screw is screwed, the end portion thereof is tightly pressed against the surface of the support 3. In this way, the entire limiting unit can be freely disassembled and installed relative to the support. When the roll material is sleeved, the limiting unit at the sleeving end of the rotary drum structure can be disassembled. After the roll material is sleeved, the limiting unit is installed relative to the support. The cooperation of the positioning screw and the positioning screw hole can accurately determine the installation position of the fixed end structure relative to the support. The locking screw of the movable end structure can lock the length of the limiting structure after the self-adaptive adjustment of the adjusting structure is completed, so that after the sleeving position of the roll material is centered, the position of the roll material in the subsequent unwinding process is ensured not to shift.

[0021] The positioning screw holes are arranged in the axial direction. The multiple positioning screw holes at both ends of the support 3 are symmetrical about the axial center position of the rotary drum structure. The fixed position of the fixed end structure on the support can be changed. The limiting structures on both sides are changed simultaneously and maintain a symmetrical relationship. By changing the axial position of the fixed end, the lateral pushing strength on the roll material can be flexibly adjusted.

[0022] The sliding end structure 22 comprises a limiting piece 23 fixedly connected on the corresponding sliding block and abutting against the side end surface of the coiled material 1, and the length of the limiting piece 23 is greater than the thickness of the coiled material 1 in the radial direction of the rotating drum structure, so as to ensure the constraint force of the limiting piece on the whole side end surface of the coiled material.

[0023] The adjusting structure comprises a telescopic piece, and the two ends of the telescopic piece are fixedly connected with the fixed end structure 21 and the sliding end structure 22 respectively.

[0024] In the embodiment one, the telescopic piece is a telescopic rod, and the telescopic rod is provided with a spring piece outside, and the telescopic rod has the ability of free telescoping.

[0025] In the embodiment two, the telescopic piece is a driving cylinder, the driving cylinders on the two sides of the coiled material 1 are connected with the same hydraulic system, a distance measuring sensor is arranged between the fixed end structure 21 and the sliding end structure 22, and the distance measuring sensors of the two limiting structures 2 are electrically connected with the controller of the hydraulic system.

[0026] The above is only the preferred embodiment of the present application, and it should be pointed out that: for those skilled in the art, without departing from the principle of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered as the protection scope of the present application.
