[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0032] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0033] The following is in conjunction with the appendix Figures 1-5 This invention describes a stainless steel uncoiling device provided by some embodiments of the present invention.

[0034] Example 1

[0035] like Figures 1 to 5 As shown, this embodiment provides a stainless steel uncoiling device for continuously uncoiling stainless steel coils and achieving ridge embossing and flattening effects. Its structure includes:

[0036] Fixed base 100 and unwinding frame 110

[0037] The fixed base 100 is used to provide the installation basis of the whole machine, and the upper side of the fixed base 100 is fixedly installed with a unwinding frame 110 for placing and rotating a stainless steel coil. The unwinding frame 110 and the fixed base 100 are fixed by welding or bolt connection or the like to ensure the stability of the whole machine.

[0038] The ridge pressing assembly 200

[0039] The concave roller 210 and the convex roller 220 are arranged side by side and form ridge line texture on the surface of the stainless steel coil by mutual cooperation. The surface of the convex roller 220 is provided with a ridge pressing strip 221, and the ridge pressing strip 221 adopts a two-section reverse spiral structure and is cooperatively rolled in the corresponding groove of the concave roller 210.

[0040] The first guide block 230 and the second guide block 240 are respectively used to support the concave roller 210 and the convex roller 220. The surface of the fixed base 100 is provided with a driving rod 250, the driving rod 250 is connected with the first guide block 230 and the second guide block 240, and the distance between the concave roller 210 and the convex roller 220 can be adjusted by means of lifting control.

[0041] When the stainless steel coil passes through the ridge pressing assembly 200, the ridge pressing strip 221 on the surface of the convex roller 220 and the groove of the concave roller 210 produce a rolling effect to form a convex ridge line texture on the surface of the coil, and the two-section reverse spiral design gradually extends the stainless steel coil to both sides, further enhancing the flatness.

[0042] The flattening assembly 300

[0043] The shaft guide frame 310 provides support and guidance for the supporting roller 320 and the rolling roller 330 and drives the supporting roller 320 to rotate synchronously through the driving teeth 311 or other transmission mechanisms.

[0044] The supporting roller 320 and the rolling roller 330 are arranged oppositely and are used to apply pressure flattening effect on the surface of the stainless steel coil. The supporting roller 320 can have two groups, and the rolling roller 330 is slidably installed on the inner side of the shaft guide frame 310.

[0045] The pressure guide strip 312 and the lever pressing plate 313: the pressure guide strip 312 can be adjusted in lifting on the shaft guide frame 310 through a screw rod assembly or the like mechanism, and the bottom surface is arc convex, and abuts against the lever pressing plate 313. The lever pressing plate 313 is in contact with the top surface of the rolling roller 330 and maintains a certain pressure, and can be freely deflected, evenly distributes the downward pressure on the rolling roller 330, so that the stainless steel coil obtains more uniform flattening effect when passing through.

[0046] Working principle

[0047] The stainless steel coil is firstly placed on the unwinding frame 110, and is unwound by rotation and then enters the ridge pressing assembly 200. When passing through the pressing area formed by the convex roller 220 and the concave roller 210, the coil is pressed to form ridge lines, and the double helical convex strips 221 help the coil to extend to both sides, relieving the middle convex and both sides lifting.

[0048] The stainless steel coil with ridge lines continues to move forward to the flattening assembly 300, and is further flattened and leveled under the cooperation of the supporting roller 320 and the roller 330. Since the lever pressing plate 313 can be freely deflected with the pressing guide strip 312 contact point as the fulcrum, the left and right rollers 330 can receive balanced downward pressure, and finally the purpose of eliminating the pressure lines and improving the flatness is achieved.

[0049] The entire process can be driven by hydraulic or electric mechanism, so that the adjustment of the gap between the concave roller 210 and the convex roller 220, the lifting adjustment of the pressing guide strip 312, and the rotation transmission of the supporting roller 320 are all automatically controlled, ensuring the production efficiency and the quality of the finished product.

[0050] The device described in the embodiment has simple structure, easy operation and maintenance, and can meet the requirements of uncoiling and flattening of stainless steel coils of various specifications and thicknesses.

[0051] Embodiment two

[0052] On the basis of the structure substantially same as that of embodiment one, the inclined installation of the driving rod 250 is further optimized, so that the distance between the convex roller 220 and the concave roller 210 can be adjusted more flexibly and efficiently. The inclined arrangement of the driving rod 250 and the second guide block 240 can save the occupied space while meeting the height adjustment. The other parts not mentioned are the same as those of embodiment one or can be combined with each other.
