Description

Technical Field

[0001] This utility model relates to the field of steel strip processing equipment, and in particular to a feeding device for a film unwinding frame. Background Technology

[0002] In order to enhance the protection of steel strips and reduce rust and wear during the processing of steel strips, a thin film can be attached to the surface of the steel strips during the packaging process. The film protects the surface of the steel strips, improves the safety during packaging and storage, and reduces rust and scratches.

[0003] Film typically requires an unwinding rack for unwinding and then adhered to the surface of a moving steel strip. To extend the continuous working time of the unwinding rack and reduce downtime, longer films are needed, meaning the outer diameter of the rolled film is relatively large and its weight is heavy. This makes it difficult for a single person to load the film, requiring multiple people to cooperate in the loading operation, which increases operational risks and labor costs, necessitating improvements. Utility Model Content

[0004] The purpose of this invention is to provide a feeding device for a film unwinding frame, which improves the ease of film feeding operation and safety.

[0005] To achieve this objective, the present invention adopts the following technical solution: A feeding device for a film unwinding frame includes: an unwinding shaft, an electric hoist, a boom, and a lifting belt. The unwinding shaft is concentrically arranged in the rolled film. The electric hoist is movably suspended above the unwinding frame. The boom is horizontally arranged below the hook of the electric hoist. Steel wire ropes connected to the hooks are provided at both ends of the boom. The lifting belt is provided at both ends of the boom for lifting the ends of the unwinding shaft. Elastic rubber particles are spaced apart in the area of ​​the lifting belt that contacts the unwinding shaft.

[0006] The unwinding shaft is an air-expanding shaft.

[0007] The elastic rubber particles are spherical or hemispherical rubber particles.

[0008] The boom has lugs spaced apart on both sides, and the lifting sling has rings at both ends corresponding to the lugs.

[0009] It also includes crossbeams and longitudinal beams. The crossbeams are horizontally suspended above both sides of the unwinding path of the unwinding frame, and the longitudinal beams are vertically suspended above the two crossbeams. The ends of the longitudinal beams are respectively provided with trolleys located on the corresponding crossbeams, and the electric hoist is suspended below the longitudinal beams.

[0010] The longitudinal beam has sliding grooves on both sides, and the electric hoist has booms on both sides that extend upward to the corresponding sides of the longitudinal beam. Rollers located in the sliding grooves are provided on the inner side of the booms.

[0011] The unwinding frame is equipped with a rotating shaft, and two cantilever arms are spaced apart on the rotating shaft. Each cantilever arm has a clamp corresponding to the unwinding shaft at both ends.

[0012] The beneficial effects of this utility model are as follows: A feeding device for a film unwinding frame uses an electric hoist to raise and lower the boom, and in conjunction with the lifting belt, lifts the unwinding shaft and film, and then moves them onto the unwinding frame, which improves the ease of feeding operation. Moreover, the elastic rubber particles deform during the extrusion process, increasing the friction with the unwinding shaft, avoiding the problem of relative slippage between the lifting belt and the unwinding shaft, and improving operational safety. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 yes Figure 1 A magnified view of part A in the middle. Detailed Implementation

[0014] The following is combined Figures 1 to 2 The technical solution of this utility model will be further illustrated through specific embodiments.

[0015] like Figure 1 The film unwinding frame feeding device shown is used for feeding film 5 onto the unwinding frame. It includes: unwinding shaft 4, electric hoist 1, lifting rod 2, lifting belt 3, crossbeam 12 and longitudinal beam 13. The unwinding shaft 4 is concentrically arranged in the rolled film 5. In this embodiment, the unwinding shaft 4 is an air-expanding shaft, which is easy to disassemble and assemble and can improve the stability of film 5 on the unwinding shaft 4.

[0016] A rotating shaft 8 is provided on the unwinding frame 7, and two cantilever arms 6 are spaced apart on the rotating shaft 8. Each cantilever arm 6 has a clamp 9 at both ends corresponding to the unwinding shaft 4, which can clamp both ends of the unwinding shaft 4. Figure 1 As shown, each of the clamps 9 at both ends of the cantilever 6 corresponds to a set of unwinding shafts 4. When one set of unwinding shafts 4 is unwinding, the other set of unwinding shafts is loading and unloading materials, without affecting each other.

[0017] The electric hoist 1 is movably suspended above the unwinding frame 7. In this embodiment, the crossbeam 12 is horizontally suspended above both sides of the unwinding path of the unwinding frame 7. The crossbeam 12 can be fixed by the building in the workshop, or a bracket can be added to support and fix the crossbeam 12.

[0018] The longitudinal beam 13 is suspended longitudinally above the two crossbeams 12. The ends of the longitudinal beam 13 are respectively provided with trolleys 10 located on the corresponding crossbeams 12. The trolleys 10 can be pushed manually or driven by electric wheels for lateral movement, providing flexibility.

[0019] like Figure 1 As shown, the electric hoist 1 is suspended below the longitudinal beam 13. In this embodiment, the longitudinal beam 13 has grooves on both sides and can be an I-beam structure. The electric hoist 1 has booms 14 extending upwards to the corresponding sides of the longitudinal beam 13 on both sides. Rollers 15 located in the grooves are provided on the inner side of the booms 14, providing rolling support for the longitudinal movement of the electric hoist 1. The rollers 15 can be driven by a motor or the electric hoist 1 can be manually pushed for longitudinal movement.

[0020] The boom 2 is horizontally positioned below the hook 11 of the electric hoist 1. Both ends of the boom 2 are equipped with wire ropes 16 connected to the hook 11, exhibiting high tensile strength. Figure 1 As shown, the hanger rod 2 is made of hollow square steel, which has high strength, good bending resistance, and light weight.

[0021] The lifting slings 3 are set at both ends of the lifting rod 2 for lifting the two ends of the unwinding shaft 4. In this embodiment, the two sides of the lifting rod 2 are provided with hanging ears 17 at intervals, and the two ends of the lifting slings 3 are provided with hanging rings 18 corresponding to the hanging ears 17. The hanging rings 18 are used to select the corresponding hanging ears 17 for suspension, and the distance between the two lifting slings 3 is changed to adapt to unwinding shafts 4 of different lengths.

[0022] The hoist 1 raises the boom 2, and the lifting belt 3 drives the unwinding shaft 4 and the film 5 on the unwinding shaft 4 to rise. Then, the electric hoist 1 is adjusted to move horizontally and vertically so that the unwinding shaft 4 is positioned between the clamps 9 of the two cantilever 6. The two ends of the unwinding shaft 4 are clamped by the clamps 9 to complete the feeding operation of the film 5. This operation can be carried out by a single person.

[0023] To enhance safety, elastic rubber granules 19 are spaced apart on the inner side of the lifting sling 3 in the area where it contacts the unwinding shaft 4. These elastic granules 19 are spherical or hemispherical rubber particles, fixed to the inner side of the lifting sling 3 in the area where they contact the unwinding shaft 4 with an adhesive, preventing them from falling off. During lifting, the elastic rubber granules 19 deform under pressure, increasing friction with the unwinding shaft 4 and preventing relative sliding between the lifting sling 3 and the unwinding shaft 4, thus improving operational safety.

[0024] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
