Description

Technical Field

[0001] This utility model relates to the technical field of roller-rolling devices, specifically a pressure adjustment mechanism for a roller-rolling device for papermaking. Background Technology

[0002] In the papermaking industry, the rubber roller counter is a core piece of equipment for paper pressing and surface treatment processes. Its pressure adjustment mechanism ensures uniform paper thickness and a smooth surface during the pressing process by adjusting the distance and pressing force between the two rubber rollers. Currently, most common pressure adjustment mechanisms employ hydraulic or direct motor drives.

[0003] In the existing technology of the papermaking industry, the pressure regulating mechanism using electric cylinders as the driving source is gradually increasing. However, since the pressure regulation of rubber rollers requires a large force, the electric cylinder needs to withstand a high load, which can easily lead to cylinder fatigue or even failure after long-term use.

A mounting plate is fixedly connected at the common position of the two limiting blocks. A second rubber roller is rotatably connected to the bottom end of the mounting plate. An extrusion shaft is fixedly connected to the side of each of the two limiting blocks that are far apart from each other. A round shaft is rotatably connected to the side of the second support plate that is close to the extrusion shaft. An extrusion plate is rotatably connected to the round shaft. The extrusion plate is movably connected to the extrusion shaft. A transmission rod is fixedly connected to one side of the two extrusion plates. An electric cylinder is fixedly installed on the top side of the second support plate. A transmission plate is fixedly connected to the output end of the electric cylinder. The transmission plate is sleeved on the transmission rod and is movably connected to the transmission rod.

[0006] Preferably, the mounting plate has an I-shaped structure design and is fitted to the second support plate.

[0007] Preferably, the extrusion plate has a frame-shaped structure design, and the corners of the extrusion plate are chamfered.

[0008] Preferably, the transmission rod has a cylindrical structure and its surface is coated with a wear-resistant layer.

[0009] Preferably, a groove is provided at the middle position of the transmission plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are: by forming a lever effect through the extrusion plate, transmission rod and transmission plate, the output force of the electric cylinder is not only efficiently transmitted to the limit block, but also the direct load of the electric cylinder is reduced, thereby extending its service life, while enhancing the stability and durability of the equipment, and reducing energy consumption and maintenance costs.
