Description

Technical Field

[0001] This invention relates to a paper roll holder that facilitates feeding, and belongs to the technical field of paper roll holders. Background Technology

[0002] Papermaking is an important invention of the ancient Chinese working people. It has two forms: machine-made and handmade. Machine-made papermaking is carried out continuously on a papermaking machine. Pulp suitable for paper quality is diluted with water to a certain concentration, and then initially dewatered in the wire section of the papermaking machine to form a wet sheet. After pressing and dewatering, it is then dried into paper.

[0003] Modern papermaking equipment requires paper rolls to be transferred to other processes such as slitting after they are made. Due to the different requirements of paper rolls, some paper rolls are suitable for vertical placement, while others are not suitable for vertical placement and can only be placed horizontally. This requires the use of different feeding supports, which is inconvenient.

[0004] Therefore, the present invention proposes a new solution. Summary of the Invention

[0005] The main objective of this invention is to address the shortcomings of existing technologies by providing a paper roll support that facilitates feeding.

[0006] The objective of this invention can be achieved by adopting the following technical solution:

[0007] A paper roll holder for easy loading includes a movable chassis. A support frame is mounted on the top of the movable chassis. A first hydraulic telescopic rod is mounted on the top of the movable chassis, located inside the support frame. The output end of the first hydraulic telescopic rod is connected to a lifting frame that is slidably connected to the support frame. A support frame is fixedly connected to the middle of one side of the lifting frame. A rotating block is rotatably mounted on one end of the support frame. An air expansion shaft is fixedly connected to one side of the rotating block. A second hydraulic telescopic rod is rotatably mounted on the inner side of the support frame. The output end of the second hydraulic telescopic rod is eccentrically rotatably connected to the rotating block.

[0010] Preferably, the support frame includes two slide bars and two vertical bars located on one side of the slide bars, with a handle connecting the top of the slide bars and the vertical bars.

[0011] Preferably, an intermediate plate is fixedly connected between the two vertical rods, and a fixing plate is connected between the intermediate plate and the sliding rod.

[0012] Preferably, the output end of the first hydraulic telescopic rod is fixedly connected to a rotating frame, a sprocket is rotatably mounted in the middle of the rotating frame, and a chain is mounted on the outer side of the sprocket, with one end mounted on the intermediate plate and the other end mounted on the lifting frame.

[0013] Preferably, a fixed frame located at the top of the support frame is fixedly connected to one side of the lifting frame, and a first rotating rod rotatably connected to the second hydraulic telescopic rod is installed in the middle of the fixed frame.

[0014] Preferably, the output end of the second hydraulic telescopic rod is connected to a hinge seat, and a hinge joint that is rotatably connected to the hinge seat is fixedly connected to one side of the rotating block. The hinge joint and the air expansion shaft are arranged perpendicularly.

[0015] Preferably, a second rotating rod is installed at one end of the support frame, and a rotating hole that cooperates with the second rotating rod is provided in the middle of the rotating block.
