Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for paper roll production, and in particular to a paper roll lifting device. Background Technology

[0002] Paper rolls, as finished paper products, are widely used in industries such as papermaking, printing, packaging, and logistics. Subsequent paper cutting, printing processing, and packaging are key intermediate carriers connecting paper production and end-use applications.

[0003] At the back end of paper roll production, it is usually necessary to place the paper rolls onto or remove them from the winding table. Existing winding tables are not compatible with forklifts, so a crane is needed to lift the paper rolls from the winding table to the ground support, and then the forklifts can move them. Alternatively, the forklifts can unload the paper rolls onto the ground, and then a person can manually push them onto the lifting platform, which will then lift them. Forklifts cannot directly connect to the lifting platform, making the process complicated and labor-intensive. Utility Model Content

[0004] The purpose of this utility model is to provide a paper roll lifting device to solve the technical problems of incompatible connection between lifting platforms and forklifts, and high manual labor intensity during unloading or loading processes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

Support rollers for supporting the paper roll are rotatably mounted on the support frame. There are two support rollers arranged in parallel. The lifting platform is equipped with a lifting assembly for lifting the paper roll on the support rollers. A gap is left between the top of the lifting assembly and the support rollers for the forks of a forklift to insert.

[0007] As a preferred embodiment of this utility model, the support roller is rotatably mounted on the support frame via a seated bearing.

[0008] As a preferred embodiment of this utility model, the lifting assembly includes lifting blocks and connecting seats. The connecting seats are bolted to the lifting platform. There are two lifting blocks, which are respectively located at both ends of the connecting seats.

[0009] As a further embodiment of this utility model, the lifting block is located between the two support rollers, and the lifting platform is located below the support rollers.

[0010] As a further preferred embodiment of this utility model, the upper end of the lifting block is provided with a detachable connecting plate, and the longitudinal center of the connecting plate is recessed relative to the two sides to form a groove.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0023] In the description of the embodiments of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of the present invention.

[0024] In the description of the embodiments of the present invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an integral connection, or a detachable connection; they can refer to the internal connection of two components; they can refer to a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the embodiments of the present invention should be understood according to the specific circumstances.

[0025] See Figures 1 to 4 As shown, the paper roll lifting device of this utility model includes a support frame 1 and a lifting platform 2. The lifting platform 2 is height-adjustable and installed inside the support frame 1 via a lifting device 20. Two support rollers 3 for supporting the paper roll are rotatably mounted on the support frame 1. The two support rollers 3 are arranged in parallel. The lifting platform 2 is provided with a lifting component 4 for lifting the paper roll on the support rollers 3. A gap is left between the top of the lifting component 4 and the support rollers 3 for the forks of a forklift to insert.

[0026] The support frame 1 provides a support base for the whole device; the lifting platform 2 is height-adjustable under the drive of the lifting device 20, which drives the lifting component 4 to move up and down; the two parallel support rollers 3 are used to carry the paper roll and can reduce friction as the paper roll rotates.

[0027] When it is necessary to transfer the paper roll, the lifting platform 2 rises so that the lifting component 4 lifts the paper roll on the support roller 3. The gap between the lifting component 4 and the support roller 3 allows the forklift forks to extend into and directly pick up the paper roll. When it is necessary to load the paper roll, the forklift forks load the paper roll above the lifting component 4. The forks descend through the gap between the lifting component 4 and the support roller 3. Once the paper roll is placed on the lifting component 4, the forks can be withdrawn. The unloading or loading process of this utility model embodiment is simplified and no additional lifting equipment is required.

[0028] It should be noted that in this embodiment of the present invention, the lifting device 20 adopts a conventional scissor lift device, that is, the lifting end of the scissor lift is connected to the lower part of the lifting platform 2, and an electronic scale 21 is provided below the scissor lift device 20.

[0029] In this embodiment of the invention, the support roller 3 is rotatably mounted on the support frame 1 via a seated bearing 301. The seated bearing 301 rotatably mounts the support roller 3 on the support frame 1, reducing the frictional resistance when the support roller 3 rotates, making it easier for the paper roll to rotate on the support roller 3, and reducing damage to the surface of the paper roll caused by friction; at the same time, the seated bearing 301 ensures the stability of the support roller 3 installation, ensuring reliable support for the paper roll.

[0030] See Figure 2 , 3 As shown, the lifting assembly 4 includes lifting blocks 401 and connecting seats 402. The connecting seats 402 are fixed to the lifting platform 2 by bolts. Two lifting blocks 401 are provided, and the two lifting blocks 401 are respectively fixed to both ends of the connecting seats 402. The connecting seats 402 are fixed to the lifting platform 2 by bolts, realizing a rigid connection between the lifting assembly 4 and the lifting platform 2, ensuring effective transmission of lifting power. The two lifting blocks 401 are located at both ends of the connecting seats 402 and are symmetrically distributed, which can evenly bear the weight of the paper roll and avoid uneven force on the paper roll during lifting, which may cause tilting or damage.

[0031] The lifting block 401 is located between the two support rollers 3, and the lifting platform 2 is located below the support rollers 3.

[0032] The lifting block 401 is located between the two support rollers 3, ensuring that it will not interfere with the support rollers 3 during lifting and can directly contact the bottom of the paper roll to achieve lifting; the lifting platform 2 is below the support rollers 3, providing sufficient lifting space for the lifting block 401 to ensure that it can smoothly lift the paper roll from below the support rollers 3 to the required height.

[0033] See Figure 3 As shown, each lifting block 401 has a detachable connecting plate 404 at its upper end. The longitudinal center of the connecting plate 404 is recessed relative to the sides to form a groove 405. When lifting the paper roll, the groove 405 acts as a buffer, reducing the pressure damage to the paper roll surface caused by rigid contact. At the same time, the groove 405 increases the friction between the paper roll and the paper roll, preventing the paper roll from shifting during lifting, enhancing the positioning effect of the paper roll, preventing the paper roll from shifting laterally during lifting or resting, dispersing the pressure of the paper roll on the lifting block 401, and improving the lifting stability.

[0034] The two lifting blocks 401 are fixedly connected by a reinforcing rod 403. The reinforcing rod 403 connects the two lifting blocks 401 into a whole, enhancing the structural strength and rigidity of the lifting assembly 4, preventing the lifting blocks 401 from deforming or shifting due to excessive force when lifting heavy paper rolls, and ensuring the stability and reliability of the lifting process.

[0035] The foregoing has shown and described the basic principles of the present invention. The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only illustrative of the principles of the present invention. Any modifications, equivalent substitutions, and improvements made within the scope of the present invention without departing from the scope of the present invention should be included within the protection scope of the present invention.
