Description

Technical Field

[0001] This utility model belongs to the field of tooling equipment technology, specifically relating to a steel strip unwinding frame. Background Technology

[0002] In polyimide film casting equipment, the quality of the conveyor belt is extremely important, as it directly affects the film casting quality and is one of the core quality control points in the quality management system.

[0003] Therefore, conveyor belts require frequent maintenance and replacement. Existing casting equipment typically uses steel strips joined end-to-end to form a loop, and the steel strip coil is the raw material for the conveyor belt.

[0004] A typical steel strip roll on the market weighs several tons, or even more than ten tons, and is extremely long. One roll of steel strip is used to make many conveyor belts, so it is difficult to use up the steel strip roll in a short period of time. However, after the packing strap is removed, the steel strip roll itself will completely loosen. The loose steel strip is prone to creases, increases the space occupied, and is also easy to cut people and is inconvenient to handle. Utility Model Content

[0005] This utility model provides a steel strip unwinding rack to solve the technical problems of existing steel strip rolls becoming loose after the packing strap is removed, which easily cause creases, increase space occupation, easily scratch people, and are inconvenient to use. This utility model includes: a base frame, the bottom of which is provided with multiple casters; Two side supports are respectively located at both ends of the bottom frame; Two bearing seats are respectively located at the top of the side bracket; A rotating shaft is provided on the two said shaft seats, and the rotating shaft is used to mount the steel strip coil; A pair of uprights are respectively installed on the same side of the two side supports; A pair of rotating rods are hinged to the upper part of the upright in a one-to-one correspondence; A pressure roller is hinged between a pair of said rotating rods, and the pressure roller is tangential to the steel strip coil.

[0006] This invention mounts the steel strip roll onto a side support via a rotating shaft and presses it down with pressure rollers, preventing the steel strip roll from loosening after the strapping is removed, allowing only the amount needed to be taken out; furthermore, the steel strip roll can be moved via casters, making it more convenient to use.

[0007] Furthermore: the bearing seat is an open groove, and the open groove has U-shaped notches on both sides of the rotating shaft; The top edges of the two sides of the open groove are also provided with guide plates. The beneficial effects of this step are: the open groove can accommodate the bearings on the rotating shaft, the U-shaped notch is used to place the two ends of the rotating shaft, and the guide plates can guide the bearings on the rotating shaft into the open groove.

[0008] Furthermore: the bearing seat is an open groove, the open groove has a U-shaped notch on the inner side wall corresponding to the rotating shaft, and the outer side wall of the open groove has a push rod at the position corresponding to the rotating shaft, the push rod being threadedly connected to the outer side wall; The top rod has a top plate at one end facing the rotating shaft, and a wrench or handwheel at the other end facing away from the rotating shaft; The top edges of both sides of the open groove are also provided with guide plates. The beneficial effect of this step is that the U-shaped notch on the inner wall is used to place the two ends of the rotating shaft. Then, the top rod on the outer wall is adjusted so that the top plate abuts against the end face of the rotating shaft, thereby limiting the rotation shaft. Finally, the guide plate can guide the bearing on the rotating shaft into the open groove.

[0009] Furthermore: at least one connecting rod is provided between the bearing seat and the upright; A connecting buckle is provided on the bottom surface of the end of the rotating rod near the pressure roller; A tension spring is provided between the connecting rod and the connecting buckle. The beneficial effect of this step is that the tension spring increases the downward pressure of the pressure roller, so as to ensure that the steel strip coil can be compacted.

[0010] Further: the rotating shaft includes: Shaft body; At least two sets of push rods are spaced apart on the shaft. Each set of push rods includes several fixed rods that are evenly distributed in a ring on the shaft. Each fixed rod has a telescopic rod at its end. The telescopic rod and the fixed rod are threaded together. The telescopic rod is also equipped with a locking nut. The beneficial effect of this step is that by adjusting the extension length of the telescopic rod on the fixed rod, the head end of the telescopic rod can abut against the inner ring of the steel strip coil, so that the steel strip coil and the rotating shaft are relatively fixed and maintain synchronous rotation.

[0011] Furthermore, the outer ring of the rotating shaft is also provided with several arc plates, which abut against the head end of the telescopic rod. The beneficial effect of this step is that the arc plates can increase the contact area with the inner ring of the steel strip roll, and prevent the telescopic rod from leaving extrusion marks on the steel strip of the inner ring.

[0012] Furthermore: a reversing roller is provided at one end of the top surface of the bottom frame near the pressure roller. The beneficial effect of this step is that the output direction of the steel strip is changed by the reversing roller, which also applies tension to the released steel strip to prevent the released steel strip from being too loose.

[0013] The beneficial effects of this utility model are: 1. This application allows the steel strip roll to rotate freely and release the steel strip through the rotating shaft, while the pressure roller above the steel strip roll can compact the steel strip roll after the strapping is released, preventing it from becoming loose, and allowing the steel strip roll to maintain a good shape without causing adverse effects. 2. This application also facilitates the relocation of the steel strip coil, making it easy to pick up and use, saving effort and time. Attached Figure Description
