Description

Technical Field

[0001] The utility model relates to the technical field of rubber roller equipment, in particular to a pressure regulating mechanism for a traction and paper pressing rubber roller. Background Art

[0002] Platen rollers are used in the papermaking process and play a crucial role in papermaking machines. Platen rollers are typically made of polymer materials such as rubber or plastic. They exhibit excellent elasticity and flexibility, are capable of transmitting high pressure, and are wear-resistant and corrosion-resistant. These properties make them useful in various industrial processes, particularly in the papermaking industry, where they are widely used in processes such as squeezing, pressing, and calendering. The design and use of platen rollers have a direct impact on paper quality. By applying appropriate pressure, they help paper achieve the desired thickness, uniformity, and smoothness. During the papermaking process, platen rollers work in conjunction with other components such as cooling rollers and calendering rollers to ensure uniform contact between the film or substrate and the adhesive, thereby producing paper products that meet standards. However, the existing traction and press paper rollers use ordinary cylinders as their power. When adjusting the traction and press paper pressure for materials of different thicknesses, it is necessary to use an open-end wrench to tighten the cylinder piston rod. The operating space is limited, the operation is inconvenient and inefficient, and each adjustment of the roller pressure takes a lot of time.

[0003] Based on the above problems, there is an urgent need for a traction paper pressing roller pressure adjustment mechanism that can be easily adjusted to adapt to materials of different thicknesses while ensuring efficiency. Utility Model Content

[0016] In the following description, specific details such as specific system structures and techniques are provided for purposes of illustration rather than limitation to facilitate a thorough understanding of the embodiments of the present application. However, it will be apparent to those skilled in the art that the present application may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid obscuring the description of the present application with unnecessary detail.

[0017] It should be understood that when used in the present specification and the appended claims, the term "comprising" indicates the presence of described features, integers, steps, operations, elements and / or components, but does not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or collections thereof.

[0018] See also Figure 1 For example, the original traction paper pressing rubber roller pressure adjustment mechanism generally uses an ordinary cylinder for the adjustment cylinder. When adjusting the traction paper pressing pressure for materials of different thicknesses, it is necessary to use an open-end wrench to tighten the cylinder piston rod. The cylinder design provides limited operating space and is inconvenient to operate, and the efficiency is very low. Based on the above problems, an embodiment of the present application discloses a traction and press-on rubber roller pressure adjustment mechanism, comprising a traction and press-on rubber roller, wherein a rubber roller core shaft is fixed through the center of the top surface of the traction and press-on rubber roller, and an adjustable stroke cylinder is fixed by a horizontal plate. The rubber roller core shaft extends a distance from the top surface of both sides of the traction and press-on rubber roller, and through holes are formed on the upper sides of the rubber roller core shafts at both ends extending a distance from the top surface of the traction and press-on rubber roller. The through holes are penetrated by the adjustable stroke cylinder to achieve a fixed connection between the adjustable stroke cylinder and the traction and press-on rubber roller. As shown in the figure, two adjustable stroke cylinders are provided and arranged on the fixed horizontal plate. The connecting rod below the adjustable stroke cylinder extends through the rubber roller core shaft. A nut is provided on the adjustable stroke cylinder. By adjusting the nut, the stroke of the adjustable stroke cylinder is changed, thereby changing the paper pressing pressure. It is worth mentioning that when the thickness of the material changes and height adjustment is required, the height of the connecting rod below the cylinder can be changed by adjusting the nut, thereby adjusting the distance between the traction and press-on rubber roller and the traction roller.

[0019] Rubber roller supports are provided on both sides of the traction paper pressing rubber roller. The rubber roller supports serve as a supporting structure, which can realize the groove support and fixation of the cross plate, the traction paper pressing rubber roller and the traction roller. A U-shaped slide is provided above the rubber roller support, and the traction paper pressing rubber roller can move up and down along the U-shaped slide, thereby realizing the adjustment of the height of the traction paper pressing rubber roller. An arc groove is provided below the rubber roller support, and the setting of the arc groove can realize the adaptation to the rotation of the traction roller.

[0020] A speed regulating valve is arranged on the outer wall of the adjustable stroke cylinder.
