Coil opening machine with deviation rectifying device for coiled materials

Abstract

The invention discloses a coil opening machine with a deviation rectifying device for coiled materials. The coil opening machine for the coiled materials comprises a worktable, a reel mechanism which is arranged on the worktable in an auto-rotation manner and a deviation rectifying mechanism which is arranged on the outer side of the reel mechanism and is positioned on the worktable; the reel mechanism comprises a drum body which can be arranged in an auto-rotation manner, and a distance between the top face of the drum body and the upper surface of the worktable can be adjusted; the deviation rectifying mechanism comprises upright posts which are arranged on the worktable and positioning pieces which are arranged on the end parts of the upright posts; the positioning pieces and the end parts of the drum body are arranged in clamping and connecting manners; and the upright posts are equipped with balanced limiting assemblies which are used for limiting the end faces of the coiled materials and are positioned between the positioning pieces and the worktable. By using the machine disclosed by the invention, the winding effect of the coiled materials can be realized, and the overall flatness effect is improved.

Description

technical field [0001] The invention relates to the field of film and coil processing equipment, in particular to an unwinder for coils with a deviation correcting device. Background technique [0002] In the production process of the film, it is often necessary to unwind the wound film roll and then rewind it tightly, and this loosening and winding operation process often requires the use of an unwinding machine for operation. [0003] The general unwinding machine realizes the unwinding of the film directly by rotating, and the flatness of the end surface of the film after winding mainly depends on factors such as the gravity of the film itself during the rotation and winding process. Therefore, this method will lead to insufficient flatness of the end surface of the film roll in the later stage, and further have a certain influence on the effect of the film roll after winding. Contents of the invention [0004] In view of the above-mentioned prior art, the object of th...

Problems solved by technology

[0004] In view of the above-mentioned prior art, the object of the present invention is to overcome the problems in the prior art that the film coil mainly relies on its own gravity to maintain the flatness of the coil surface and poor controllability during the winding process, thereby providing a An uncoiler for coils with a deviation correction device that can improve the coiling effect of the coils and improve the overall flatness
