Description

Technical Field

[0001] This utility model relates to the field of slitting machine feeding technology, specifically to an auxiliary winding device for a slitting machine. Background Technology

[0002] The winding device of the slitting machine is the core component responsible for loading and conveying the raw material rolls (such as film, paper, metal foil, etc.) to the slitting host. Its main function is to ensure the smooth operation of the rolls.

[0003] Chinese patent disclosure (CN221049126U) discloses a feeding device for a packaging bag slitting machine. It includes a frame for clamping and feeding packaging bag rolls, a lifting device for supporting the lifting and lowering of the packaging bag rolls in the middle of the frame, and a feeding device above the lifting device for swinging, pressing, and rotating the packaging bag rolls for feeding. The feeding device includes a swing frame with a first motor at one end, a drive shaft at the bottom of the swing frame, a second motor at one end of the drive shaft, and two feeding wheels symmetrically mounted on the drive shaft. This packaging bag slitting machine feeding device, through its swing-pressing mechanism, avoids loose and scattered packaging bag rolls; its electric rotation and pushing mechanism ensures controllability in packaging bag slitting and feeding; and its single-end limiting three-jaw chuck facilitates packaging bag slitting and alignment.

[0004] However, the device still has the following drawbacks: when replacing the guide rollers, the guide rollers must first be unlocked, then the electric push rod must be moved downwards, and after replacing the guide rollers, they must be installed again, which takes a long time. Therefore, we propose an auxiliary winding device for the slitting machine to solve this problem. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary winding device for a slitting machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a slitting machine auxiliary winding device, comprising a frame, wherein a feeding device is provided inside the frame, and the feeding device includes a mounting part;

[0007] The mounting part includes a mounting frame, a second locking block, a first rotating shaft, and a limiting sleeve. The limiting sleeve is slidably fitted on the outer surface of the second locking block. The outer surface of the right end of the first rotating shaft rotates through the inner wall of the mounting frame and extends to the right side of the mounting frame via a first tapered roller bearing. The outer surface of the left end of the limiting sleeve rotates through the inner wall of the mounting frame and extends to the left side of the mounting frame via a second tapered roller bearing.

The rear mounting roller can then be put into use immediately. When unwinding the rear mounting roller, the positioning bolts are rotated to replace the used mounting roller, significantly reducing equipment waiting time.

[0018] By setting up a second motor, lead screw, driving roller and driven roller, rotating the lead screw causes the driving roller to squeeze the driven roller, which facilitates the installation of the roller to discharge material;

[0019] By setting up an electric telescopic rod and a support plate, the telescopic rod can be controlled to extend and retract, making it easy to replace the front installation roller without affecting the use of the rear installation roller. Attached Figure Description

The outer surface of the left end of the second rotating shaft 219 is rotatably connected to the inner wall of the movable frame 210 through the second bearing seat. The outer surface of the mounting roller 213 is provided with a slot. The outer surfaces of the first locking block 214 and the second locking block 215 both extend into the interior of the mounting roller 213 and are slidably connected to the inner wall of the mounting roller 213. The outer surface of the roller 212 is rotatably connected to the inner wall of the mounting frame 211 through the fourth bearing seat.

[0031] The outer surface of the mounting frame 211 is provided with a threaded groove, and the thread on the outer surface of the positioning bolt 216 penetrates the outer surface of the movable frame 210 and extends into the interior of the mounting frame 211.

[0032] The bottom surface of the electric telescopic rod 201 is fixedly connected to the inner wall of the frame 1, and the top surface of the output rod of the electric telescopic rod 201 is fixedly connected to the bottom surface of the support plate 202. By setting the electric telescopic rod 201 and the support plate 202, the telescopic rod 201 can be controlled to extend and retract, which facilitates the replacement of the front installation roller 213.
