Description

Technical Field

[0001] The utility model relates to the technical field of unwinding machines, in particular to an unwinding device. Background Art

[0002] The unwinder is an important equipment on the stainless steel strip punching production line. The unwinder mainly includes a spindle chassis, a spindle and a tensioning mechanism. When the steel strip needs to be unwound, the user puts the steel strip roll on the tensioning mechanism of the unwinder, and the tensioning mechanism tightens the inner wall of the steel strip roll. The unwinder spindle drives the tensioning mechanism to rotate, and the tensioning mechanism drives the steel strip roll to rotate, thereby achieving the unwinding effect.

[0003] The Chinese patent publication number CN218433939U proposes "a reel with a clamping mechanism". The technical solution proposes the problem that "when the reel is about to finish the reeling operation of the steel strip, the last few turns of the steel coil are prone to bounce off under the action of their own elasticity, which will pose a threat to the safety of the user". The utility model provides the following technical solution: "When the user uses it, he presses the rotating disk with his hand and turns the adjusting screw. The adjusting screw drives the sliding support to slide along the radial direction of the rotating disk away from the axis of the rotating disk; in this process, all the sliding supports jointly drive the elastic tension ring to tighten, and the elastic tension ring corresponding to the clamping groove expands. The two clamping blocks move closer to each other, and the steel coil is sleeved on the outer wall of the elastic tensioning ring, so that the end of the innermost coil is inserted between the two clamping blocks and clamped; after the steel coil is installed, the rotating disk is loosened and the adjusting screw is turned. The friction between the adjusting screw and the rotating disk is less than the friction between the rotating disk and the support seat. The adjusting screw drives the rotating disk and the steel coil to rotate together to unwind the steel coil. This design can clamp the inner steel ring while tightening the steel coil. When the steel coil is unwound to the last few turns, it can also effectively reduce the probability of the steel coil bouncing off, and to a certain extent prevent the bouncing steel coil from causing damage to the staff.

[0004] The above scheme also has the following defects: when using the above device, it is necessary to control the sliding support plate to slide away from the axis of the rotating disk in order to fix the steel belt. However, common steel belt rolls are very heavy. At this time, the steel belt roll needs to be lifted up before it can be docked with the rotating disk. The above device does not have an auxiliary winding structure, so the above device is more difficult to operate. Therefore, a rewinding device is proposed to solve the above problem.

[0010] The beneficial effect of adopting the above further solution is that the inner ring of the steel strip coil can be fixed inside the rotating disk by the provided extrusion fixing mechanism.

[0011] Furthermore, the cross-section of the groove bottom plate is a "concave" structure, the left side plate is located at an end close to the left side of the groove bottom plate, and the right side plate is located at an end close to the right side of the groove bottom plate.

[0012] The beneficial effect of adopting the above further solution is that the bottom of the device is supported by the groove bottom plate.

[0013] Furthermore, the exterior of the movable plate is a rectangular structure, the stepper motor is located on the symmetry axis of the mounting side frame, and the threaded rod is rotatably mounted inside the mounting side frame.

[0015] Furthermore, the moving block slides up and down inside the mounting side frame, the outside of the support plate is semicircular, the two limit blocks are both located at one end close to the top of the support plate, and the two limit blocks slide up and down outside the two vertical rods respectively.

[0016] The beneficial effect of adopting the above-mentioned further scheme is that the forward and reverse rotation of the threaded rod can realize the movable block driving the pallet to rise and fall on the left side of the mounting side frame, so that the pallet lifts the steel strip roll, and the pallet on the left side of the two limit blocks is restricted to the left side of the mounting side frame by two vertical rods, thereby making the lifting of the pallet more stable.

[0017] Furthermore, a motor for driving a gear to rotate is fixedly mounted on the surface of the front lower support plate, and the gear is meshed and mounted on the top of the rack.

[0022] The beneficial effect of adopting the above-mentioned further scheme is that the electric push rod can be extended and retracted to drive the block to move left and right inside the rotating disk. The left and right movement of the block inside the rotating disk can drive the four arc outer support plates to expand and retract simultaneously inside the rotating disk through four connecting rods. The four arc outer support plates can expand outward at the same time to squeeze and fix the inner circle of the steel strip roll on the inner cavity side wall of the rotating disk.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] The unwinding device drives the threaded rod to rotate forwardly through a stepper motor, which can force the support plate to drive the steel coil to rise. After the steel coil is flush with the rotating disk, the motor drives the gear to rotate counterclockwise to drive the movable plate and the steel coil on its top to move closer to the rotating disk, so that the outer coil of the steel coil can be easily sleeved on the outside of the four arc outer supporting plates. After that, the electric push rod pulls the block to move to the left, causing the four arc outer supporting plates to expand outward, so that the outer coil of the steel coil can be memorized and fixed inside the rotating disk, thereby achieving the effect of convenient operation and labor saving.
