Description

Technical Field

[0001] The utility model relates to the technical field of rewinding machines, in particular to an automatic balancing device for a paper pressing roller of a rewinding machine. Background Art

[0002] A rewinder is a device used to rewind paper rolls. Its primary function is to rewind large rolls of paper into smaller rolls that meet specific specifications and quality requirements. Rewinders are widely used in the papermaking, printing, and packaging industries. In paper mills, they are used to further process the original paper rolls; in the printing industry, they rewind printed paper into rolls suitable for subsequent processing or use. The rewinder's pressure roller is a crucial component, typically located in a suitable position within the rewinder. Its primary function is to apply pressure to the paper during the rewinding process, ensuring a tight and neat roll.

The balancing mechanism includes a fixed plate, a connecting plate, two springs, two support plates and two groups of paper pressing assemblies. The two support plates are fixedly connected to the top of the support platform, the fixed plate is fixedly connected to the top of the support plate, one end of the two springs is symmetrically fixedly connected to the bottom of the fixed plate, and the connecting plate is fixedly connected to the other end of the spring. The two groups of paper pressing assemblies each include a rotating shaft, a paper pressing roller and two fixed blocks, and the two fixed blocks are fixedly connected to the connecting plate. The utility model balances the tension of the paper tape, making it smoother during rewinding, with neater cutting edges and tighter winding. The elastic force of the spring can adapt to paper tapes of different thicknesses and materials, making it easy to promote and solving the problem that the tension of the paper tape changes during movement, resulting in uneven cutting edges and loose winding when entering the rewinder. In daily work, it is found that the above-mentioned automatic balancing device for the rewinder's pressure roller mainly realizes automatic balancing of the paper through a spring, but when the rewinder's pressure roller rotates, it is not convenient to limit the running paper, and the paper is prone to offset.

[0021] Specifically, the auxiliary device 5 includes a slide rail 54, and there are two slide rails 54. The two slide rails 54 are fixedly connected to the two side surfaces of the movable plate 2 respectively. The surfaces of the two slide rails 54 are slidably connected with intercepting members 51. The surface of the movable plate 2 is fixedly connected with two support seats 58. The inner wall of the support seat 58 is rotatably connected with a screw 57.

The surface of the movable plate 2 is provided with a driving assembly 56, and the surface of the intercepting member 51 is provided with an observation assembly 55.

[0022] In this embodiment: when in use, the screw 57 can be driven to rotate by the driving component 56, and the screw 57 can control the two intercepting members 51 to move on the slide rail 54, and the intercepting member 51 can be adjusted to the specified position through observation by the observation component 55 to restrict the paper and improve the stability during winding.

[0023] Specifically, the driving assembly 56 includes a motor 561 , which is fixedly connected to the surface of the movable plate 2 , a transmission head 562 is fixedly connected to the surface of the screw 57 , and a transmission belt 563 is provided between the output end of the motor 561 and the transmission head 562 .

[0024] In this embodiment, when driving, the motor 561 is turned on, and the motor 561 drives the transmission head 562 and the screw 57 to rotate through the transmission belt 563, so as to drive and adjust the positions of the two intercepting members 51.

[0025] Specifically, the observation component 55 includes a scale 551, which is opened on one side surface of the slide rail 54. An observation port 552 is opened on the side of the intercepting member 51 close to the scale 551.
