[0002] With social development and the increasing variety of goods, people are paying more and more attention to the outer packaging of goods. Corrugated paper is one of the important materials for outer packaging of goods, so the demand for corrugated paper is increasing day by day. In order to better cater to consumers, corrugated paper manufacturers are also setting up factories like mushrooms after rain.

[0003] Currently, corrugated rolls are used in corrugated paper production lines. These rolls effectively control the moisture content of the corrugated paper, thus controlling the finishing effect. Therefore, corrugated rolls play a crucial role in the corrugated paper production line. During production, corrugated rolls need to be transferred to different processing equipment. However, corrugated rolls are generally large, making manual handling inconvenient and impractical. Therefore, lifting equipment is required for transfer. Existing lifting fixtures are generally only suitable for corrugated rolls of one diameter. When transferring corrugated rolls of different diameters, multiple lifting fixtures of different specifications need to be prepared, increasing production costs and occupying workshop space.

[0004] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a corrugated roll lifting fixture applicable to multiple diameters, aiming to solve the technical problems of low applicability of existing lifting fixtures and the need to prepare lifting fixtures of multiple diameters to meet production needs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

Each main body includes a clamping part with two intersecting clamping surfaces on its inner side. The two main bodies are arranged opposite each other, and the four clamping surfaces enclose a quadrilateral to clamp the corrugated roll. The distance between the two main bodies can be adjusted by screws.

[0008] The aforementioned corrugated roll lifting fixture applicable to various diameters includes two connecting parts in the main body. The two connecting parts are respectively connected to the two ends of the clamping part and are arranged close to the inner side of the clamping part.

[0009] The aforementioned corrugated roll lifting fixture applicable to various diameters includes a connecting part with multiple connecting holes. The number of connecting holes on a single main body is the same as the number of screws, and the connecting holes are used to install the screws.

[0010] The aforementioned fixture for lifting corrugated rolls of various diameters includes a transition plane on the inner side of the included angle of the clamping part, with the two ends of the transition plane connected to two clamping surfaces respectively.

[0011] The aforementioned corrugated roll lifting fixture applicable to various diameters includes a mounting plane on the outer side of the clamping part, and a mounting hole recessed inward from the mounting plane, which accommodates a lifting ring.

[0012] The aforementioned corrugated roll lifting fixture applicable to various diameters has a rounded corner at the connection of the outer connecting part of the clamping part.

[0013] The aforementioned corrugated roll lifting fixture applicable to various diameters also includes washers, which are fitted onto the screw and located between the main body and the nut.

[0014] Beneficial effects:

[0015] This invention provides a lifting fixture suitable for corrugated rolls of various diameters, comprising two main bodies connected by a screw. Each main body includes a clamping section with two clamping surfaces. Before lifting and transferring the corrugated roll, one end of the roll is inserted between the clamping sections of the two main bodies, and the nut on the screw is tightened, causing the clamping surfaces to fit tightly against the end side of the roll, thus achieving clamping and fixation. This lifting fixture, suitable for corrugated rolls of various diameters, clamps the roll by connecting two main bodies with a screw. Adjusting the distance between the two main bodies allows for the installation of corrugated rolls of different diameters, eliminating the need to prepare multiple lifting fixtures of different specifications, reducing costs for manufacturers, and is easy to use.

[0026] Please see Figures 1 to 2 As shown, this utility model provides a lifting fixture suitable for corrugated rolls of various diameters. It includes two main bodies 1, connected by multiple screws 2 and nuts 3. Each main body 1 includes a clamping portion 11 with two intersecting clamping surfaces 12 on its inner side. The two main bodies 1 are positioned opposite each other, and the four clamping surfaces 12 form a quadrilateral to clamp the corrugated roll. The distance between the two main bodies 1 can be adjusted via the screws 2. In this embodiment, four screws 2 are used, specifically double-ended screws, resulting in eight nuts 3. The four screws 2 are positioned in pairs on both sides of the clamping portion 11, connecting the two main bodies 1. Before lifting and transferring the corrugated roll, one end of the roll is inserted between the clamping portions 11 of the two main bodies 1, and the nuts 3 on the screws 2 are tightened, causing the clamping surfaces 12 to fit tightly against the end side of the corrugated roll, thus achieving clamping and fixing. This lifting fixture, applicable to corrugated rolls of various diameters, uses a screw 2 to connect two main bodies 1 to clamp the corrugated rolls. Adjusting the distance between the two main bodies 1 allows it to accommodate corrugated rolls of different diameters. It eliminates the need to prepare multiple lifting fixtures of different specifications, reducing the cost for manufacturers in terms of lifting fixtures, and is also easy to use.

[0027] Please see Figures 1 to 2As shown, the main body 1 also includes two connecting parts 13, which are respectively connected to both ends of the clamping part 11. The two connecting parts 13 are disposed near the inner side of the clamping part 11. In this embodiment, the two connecting parts 13 and the clamping part 11 are integrally formed. The fact that the connecting parts 13 are disposed near the inner side of the clamping part 11 facilitates a shorter connection distance between the two main bodies 1, and requires a shorter screw 2, which helps to save manufacturing costs.

[0028] Please see Figure 2 As shown, the connecting part 13 is provided with multiple connecting holes 14. The number of connecting holes 14 on a single main body 1 is the same as the number of screws 2. The connecting holes 14 are used to install screws 2. In this embodiment, a main body 1 has four connecting holes 14, which are arranged in pairs on two connecting parts 13. The two connecting holes 14 on the same connecting part 13 are distributed on the diagonal of the connecting part 13, so that the two screws 2 are staggered and the nuts 3 of the two screws 2 are also staggered. This eliminates the need for a large connecting part 13, reduces the raw material cost of the main body 1, and reduces the overall weight of the lifting fixture.

[0029] Please see Figure 2 As shown, a transition plane 15 is provided on the inner side of the included angle of the clamping part 11, and the two ends of the transition plane 15 are respectively connected to the two clamping surfaces 12. In this embodiment, the transition plane 15 is provided between the two clamping surfaces 12 for connection, which can strengthen the strength of the clamping part 11, make the clamping part 11 less prone to cracking, and extend the service life of the lifting fixture.

[0030] Please see Figure 2 As shown, a mounting plane 16 is provided on the outer side of the included angle of the clamping part 11, and a mounting hole 17 is recessed inward from the mounting plane 16. The mounting hole 17 accommodates and installs a lifting ring 4. In this embodiment, a universal lifting ring 4 is selected, which can rotate 360° for easy use. The outer side of the included angle of the clamping part 11 is made into a plane to facilitate the installation of the lifting ring 4.

[0031] Please see Figure 2 As shown, the connection of the outer connecting part 13 of the clamping part 11 is provided with a rounded corner 18, which can increase the connection strength between the clamping part 11 and the connecting part 13, and prevent the clamping part 11 from being squeezed by the corrugated roller, which would reduce the angle between the clamping part 11 and the connecting part 13 and thus affect the service life of the entire hoisting fixture.

[0032] Please see Figure 1 As shown, it also includes a washer 5, which is sleeved on the screw 2 and located between the main body 1 and the nut 3. The washer 5 improves the locking tightness of the nut 3 on the screw 2, preventing loosening between the two main bodies 1 and thus avoiding the corrugated roller clamped on them from falling off and causing an accident. In this embodiment, a flat washer is selected for the washer 5.

[0033] In summary, this utility model uses a screw 2 to connect two main bodies 1 to clamp the corrugated roller. Adjusting the distance between the two main bodies 1 allows it to be used for corrugated rollers of different diameters. It eliminates the need to prepare multiple lifting fixtures of different specifications, reducing the cost of lifting fixtures for manufacturers, and is also convenient to use.

[0034] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of the appended claims of this utility model.
