Description

Technical Field

[0001] The utility model relates to the technical field of unwinding racks, in particular to an unwinding rack which is easy to adjust. Background Art

[0002] The uncoiler is a special equipment for leveling metal plates. It is used to level steel plates and uneven plates. It can be used to form uncoiler, leveling, shearing production lines and other plate product production lines according to relevant configurations. It is suitable for machinery, vehicles, metal products, household appliances, steel structures, decoration and other industries.

[0003] However, in the unwinding process of the traditional uncoiler, the unwinding rack is used to fix the objects to be unwinded. In order to ensure the stability of the objects, a guard arm is used to fix the objects to be unwinded. However, the guard arm needs to be disassembled and installed each time the coil is unwound, which is extremely complicated, time-consuming and labor-intensive to use, thus increasing the manufacturing cost.

[0004] For example, Chinese patent CN208390690U discloses a material unwinding rack for coils of an uncoiler, in which a base, a mounting seat, a rotating shaft, a support column, a support seat, an arc plate, a fixed seat and a support rod are matched to set the article to be unwound on the outer wall of the arc plate, and the base, the mounting seat, the rotating shaft, the support column, the support seat, the arc plate, the fixed seat, the support rod, the handle, the first bevel gear, the second bevel gear, the clamping rod, the threaded groove, the threaded rod, the limit block and the fixed rod are matched to shake the handle, the handle drives the support rod to rotate, the support rod drives the first bevel gear to rotate, and the first bevel gear drives the second bevel gear located directly above the support rod to rotate , the second bevel gear drives the threaded rod to rotate, and the threaded rod drives the clamping rod to move upward. At the same time, the first bevel gear drives the second bevel gear located directly below the support rod to rotate, and the second bevel gear drives the threaded rod to rotate, and the threaded rod drives the clamping rod to move downward, thereby fixing the object to be unrolled, and then turning on the motor to unwind. The use of this device effectively prevents the objects on the material rack from being thrown out of the material rack due to rotation, thereby preventing waste of materials and damage to the machine. When the unwinding is completed and the material needs to be placed again, just shake the handle to re-place the material. It is simple and convenient, saves time and effort, and effectively reduces the possibility of the unrolled material falling off.

[0005] However, the device cannot fix the objects to be unwound with different inner diameters on the unwinding rack during use, and has limitations in use and low practicality.

[0006] For this reason, we urgently need to provide a kind of unwinding and unwinding rack that is easy to adjust. Utility Model Content

[0012] Preferably, the connecting parts are symmetrically distributed around the outer side of the disc, and the end of the connecting parts away from the disc is rotatably connected to one side of the fixed plate. The threaded rod is driven to rotate by rotating the remote rod. When the threaded rod is threadedly connected to the disc, the connecting parts are driven to rotate around the disc and the fixed plate, and the fixed plate is pushed to move outward or toward, thereby facilitating the fixation of objects to be unwound with different inner diameters.

[0013] Preferably, symmetrically distributed sliding grooves are provided around the outer surface of the support column to prevent the connecting piece from being blocked by the support column when rotating.

[0014] Preferably, the guide rod 2 is fixedly connected to the top of the telescopic member and the support platform. By starting the telescopic member, the support platform is pushed down along the guide rod 2, thereby facilitating the unwinding of the object on the support column. There is no need for workers to lift the object and then put it on the outside of the support column, thereby reducing the labor intensity of workers.

[0015] Preferably, the number of the guide rods is eight and two are symmetrically distributed on the outer surface of the support column in a group, and the guide rods play a limiting role through the movement of a pair of fixed plates.

[0016] Preferably, a rubber pad is installed on the outer surface of the fixing plate, so as to prevent the fixing plate from abutting against the inner diameter of the object to be unwound, thereby preventing the unwound object from being scratched.
