Description

Technical Field

[0001] This utility model relates to the field of metallurgical processing technology, specifically to a large-diameter metallurgical paper sleeve with an oblique stress distribution structure. Background Technology

[0002] Metallurgy is the process of extracting metallic raw materials from minerals or other substances containing metallic substances. It starts from mining and ends with metal purification, covering the entire refining and extraction process. It is usually used for processing materials such as steel, iron, gold, silver, and copper. The extraction methods are nothing more than pyrometallurgical, hydrometallurgical, and electrolytic techniques.

[0003] When metal materials are refined and rolled into thin metal sheets, paper sleeves are used to wrap and collect them. These paper sleeves have a certain thickness and hardness so that they will not collapse under the wrapping of layers of metal sheets. However, these paper sleeves are often affected by axial and radial combined stresses during transportation, and the paper sleeves are inevitably squeezed and broken, and the wrapped metal sheets will also be damaged.

[0004] Now, a novel large-diameter metallurgical paper sleeve with an oblique stress distribution structure is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a large-diameter metallurgical paper sleeve with an oblique stress distribution structure to solve the problem of easy collapse of paper sleeves mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a large-diameter metallurgical paper sleeve with an oblique stress distribution structure, including an inner paper tube, an outer paper tube fixed to the outer surface of the inner paper tube, and a spiral paper strip I wound around the outer surface of the outer paper tube, a spiral groove formed between adjacent spiral paper strips I, and a spiral paper strip II wound in the spiral groove.

[0007] As a further technical solution of this utility model, the first spiral paper strip and the second spiral paper strip have the same winding direction, and the width of the second spiral paper strip matches the spiral groove.

[0008] As a further technical solution of this utility model, a transverse groove is provided between the left and right sides of the inner circumference of the outer paper tube, and a transverse metal wire is inserted and fixed in the transverse groove. A large annular groove is provided longitudinally inside the outer paper tube, and a small annular groove is provided in the gap between the large annular grooves. A second metal ring is fixed in the large annular groove, and a first metal ring is fixed in the small annular groove.

[0009] As a further technical solution of this utility model, both the first metal ring and the second metal ring are connected to multiple transverse metal wires, and the first metal ring, the second metal ring and the transverse metal wires are of the same thickness.

[0010] As a further technical solution of this utility model, insertion grooves are respectively provided on the inner walls on both sides of the inner paper tube, and a retaining ring is snapped and fixed in the insertion groove. A positioning paper sleeve is horizontally fixed on the outer side of the retaining ring, and a circular ring is fixed on the outer side of the positioning paper sleeve. A through groove is provided at the center of the circular ring.

[0011] As a further technical solution of this utility model, the retaining ring, positioning paper sleeve, ring and through groove are arranged in concentric circles, and the positioning paper sleeve moves left and right along the inner wall of the insertion groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the large-diameter metallurgical paper sleeve with oblique stress distribution structure not only prevents the paper sleeve from disintegrating and maintains the stability of the paper sleeve structure, but also strengthens the inner core of the paper sleeve from both sides.

[0013] (1) By winding a spiral paper strip one on the outer surface of the outer paper tube and a spiral paper strip two in the spiral groove, this paper sleeve is divided into two groups: an inner paper tube and an outer paper tube. The outer paper tube is fixedly sleeved on the outside of the inner paper tube, and the surface of the outer paper tube is fixedly wound with a spiral paper strip one. The spiral groove formed between multiple spiral paper strips one allows the spiral paper strip two to continue to be wound and fixed, which can form a spiral interlaced structure on the outer surface of the paper sleeve, so that the stress is dispersed along the oblique direction and avoids the single stress concentration in the axial and radial directions.

[0014] (2) By inserting and fixing transverse metal wires in the transverse grooves, transverse metal wires are inserted and fixed in the transverse grooves around the inside of the outer paper tube. The inner and outer sides of the multiple transverse metal wires are respectively connected to metal ring one and metal ring two. The two are intertwined and formed a reinforced structure with the transverse metal wires, maintaining the stability of the internal structure of the outer paper tube, preventing the outer paper tube from being deformed by pressure, and ensuring that the inner paper tube does not deform from the outside.

[0015] (3) By snapping and fixing the retaining ring in the insertion slot, the positioning paper sleeve is pushed in laterally along the insertion slots on both sides of the inner paper tube, so that the retaining ring on the inside of the positioning paper sleeve stays deep in the insertion slot, and the outer ring is flush with the two sides of the inner paper tube. The cylindrical positioning paper sleeve supports the two sides of the inner paper tube, which can prevent the two sides of the inner paper tube from being compressed and collapsing. The structure can be disassembled and reinstalled again. Attached Figure Description

The outer paper tube 6 is fixedly sleeved on the outside of the inner paper tube 1, and a spiral paper strip 11 is fixedly wound on the surface of the outer paper tube 6. The spiral groove 13 formed between the multiple spiral paper strips 11 allows the spiral paper strip 12 to continue to be wound and fixed, and a spiral interlaced structure can be formed on the outer surface of the paper sleeve for reinforcement.

[0025] A transverse groove 7 is provided between the left and right sides of the inner circumference of the outer paper tube 6, and a transverse metal wire 8 is inserted and fixed in the transverse groove 7. A large annular groove 14 is provided longitudinally inside the outer paper tube 6, and a small annular groove 15 is provided in the gap between the large annular grooves 14.

Both the first metal ring 9 and the second metal ring 10 are connected to multiple transverse metal wires 8. The first metal ring 9, the second metal ring 10 and the transverse metal wires 8 have the same thickness.

[0026] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, transverse metal wires 8 are inserted and fixed in the transverse grooves 7 around the inside of the outer paper tube 6. Metal rings 9 and 10 are respectively attached to the inner and outer sides of the multiple transverse metal wires 8. The two are intertwined and form a reinforcing structure with the transverse metal wires 8, which maintains the stability of the internal structure of the outer paper tube 6 and prevents the outer paper tube 6 from being deformed by pressure.

[0027] The inner walls on both sides of the inner paper tube 1 are respectively provided with insertion grooves 2, and a retaining ring 16 is fixed in the insertion groove 2. A positioning paper sleeve 3 is fixed laterally on the outside of the retaining ring 16, and a ring 4 is fixed on the outside of the positioning paper sleeve 3.

[0028] Specifically, such as Figure 1 and Figure 4 As shown, the positioning paper sleeve 3 is pushed horizontally into the insertion groove 2 on both sides of the inner paper tube 1, so that the retaining ring 16 on the inner side of the positioning paper sleeve 3 stays deep in the insertion groove 2, while the outer ring 4 is flush with the two sides of the inner paper tube 1. The cylindrical positioning paper sleeve 3 supports the two sides of the inner paper tube 1, which can prevent the two sides of the inner paper tube 1 from being compressed and collapsing.

[0029] Working principle: In use, a spiral paper strip 12 is wound in the spiral groove 13. The paper sleeve is divided into two groups: an inner paper tube 1 and an outer paper tube 6. The outer paper tube 6 is fixedly sleeved on the outside of the inner paper tube 1, and a spiral paper strip 11 is fixedly wound on the surface of the outer paper tube 6. The spiral groove 13 formed between the multiple spiral paper strips 11 allows the spiral paper strip 12 to continue to be wound and fixed, forming a spiral interlaced structure on the outer surface of the paper sleeve for reinforcement. A transverse metal wire 8 is inserted and fixed in the transverse groove 7 around the inside of the outer paper tube 6, and multiple wires are used for this purpose. Metal ring 19 and metal ring 20 are respectively attached to the inner and outer sides of the transverse metal wires 8. The two are intertwined and form a reinforced structure with the transverse metal wires 8 to maintain the stability of the internal structure of the outer paper tube 6. Finally, the positioning paper sleeve 3 is pushed into the insertion grooves 2 on both sides of the inner paper tube 1, so that the retaining ring 16 on the inner side of the positioning paper sleeve 3 stays deep in the insertion groove 2, and the outer ring 4 is flush with the two sides of the inner paper tube 1. The cylindrical positioning paper sleeve 3 supports the two sides of the inner paper tube 1, which can prevent the two sides of the inner paper tube 1 from being compressed and collapsing.
