Description

Technical Field

[0001] This utility model relates to the field of paper pressure roller technology, specifically to an adjustable pressure roller for improving the dry strength of paper. Background Technology

[0002] Pressure rolls play a crucial role in the papermaking process, primarily used for pressing, calendering, and shaping wet or dry paper webs to improve their physical properties and surface quality. In existing technologies, the outer surface of pressure rolls is generally smooth. Using a smooth surface for pressure rolling weakens the fiber bonding process, leading to insufficient dry strength and requiring multiple pressure cycles. Therefore, this paper proposes an adjustable pressure roll to improve paper dry strength. Summary of the Invention

[0003] The purpose of this invention is to solve the above problems by proposing an adjustable pressure roller to improve the dry strength of paper.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an adjustable pressure roller for improving the dry strength of paper, comprising a frame and a pressure roller body mounted on the frame; characterized in that the outer surface of the pressure roller body is provided with pressure roller texture to promote paper positioning and bonding and improve fiber density; an adjusting block for fixing the pressure roller body and a driving source for driving the adjusting block to slide are slidably mounted on the frame; an electromagnet for further fixing the adjusting block is also mounted on the frame.

[0005] Preferably, the pressure roller body is mounted on the adjusting block via bearings, allowing the pressure roller body to be adjustablely mounted on the frame.

[0006] Preferably, the frame is also provided with a guide groove for adjusting the adjustment block.

[0007] Preferably, the adjusting block is provided with a guide boss adapted to the guide groove and a magnet used in conjunction with the electromagnet.

[0008] Preferably, the roller texture on the roller body is a micro-groove texture or a grid texture.

[0009] The beneficial effects of this utility model are as follows: By setting the pressure roller texture on the outer surface of the pressure roller body, the contact area between the pressure roller body and the paper is increased, which promotes the bonding of paper fibers and helps the moisture and air in the paper to be discharged, thereby improving the fiber density and thus improving the strength of the paper.

[0010] By using the magnet generated by the electromagnet on the frame after being energized, the adjusting block is further fixed, which facilitates multiple fixation of the pressure roller body during production and prevents the pressure roller body from shifting during production, thereby affecting paper production.

[0011] The adjustment block is driven by a drive source to move, and the adjustment block drives the pressure roller body to adjust the pressure roller body along the frame according to the requirements of paper production, thereby expanding the range of applications. Attached Figure Description

[0016] The adjustable pressure roller for improving the dry strength of paper according to this utility model will be further described below with reference to the accompanying drawings.

[0017] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.

[0018] See appendix Figure 1-3 As shown in the figure, this embodiment of an adjustable pressure roller for improving the dry strength of paper includes a frame 1 and a pressure roller body 2 mounted on the frame 1. The roller body 2 is characterized by a pressure roller texture 201 on its outer surface that promotes paper fiber bonding and increases fiber density. The pressure roller texture 201 on the roller body 2 is a micro-groove texture or a grid texture. An adjusting block 3 for fixing the pressure roller body 2 and a driving source 301 for driving the adjusting block 3 to slide are also slidably mounted on the frame 1. The driving source 301 is one of a cylinder, a hydraulic cylinder, or an electric actuator. By providing the pressure roller texture 201 on the outer surface of the roller body 2, the contact area between the roller body 2 and the paper is increased, promoting paper fiber bonding and facilitating the removal of moisture and air from the paper, thus increasing fiber density and improving paper strength. The driving source 301 drives the adjusting block 3 to move, and the adjusting block 3 drives the roller body 2 to adjust along the frame 1 according to the requirements of paper production, thereby expanding the range of applications.

[0019] See appendix Figure 1As shown, the pressure roller body 2 is mounted on the adjusting block 3 via bearings, so that the pressure roller body 2 can be adjusted and mounted on the frame 1; the pressure roller body 2 is mounted on the adjusting block 3 via bearings, so that the pressure roller body 2 can be rotatably mounted on the adjusting block.

[0020] See appendix Figure 1 As shown, the frame 1 is also provided with a guide groove 102 for adjusting and guiding the adjusting block 3; the adjusting block 3 is provided with a guide boss 302 adapted to the guide groove 102 and a magnet 303 used in conjunction with the electromagnet 101; the frame 1 is also equipped with an electromagnet 101 for further fixing the adjusting block 3; by using the magnet generated by the electromagnet 101 on the frame 1 after being energized to attract the magnet 303 on the adjusting block 3, the adjusting block 3 is further fixed, thereby facilitating multiple fixation of the pressure roller body 2 during production, preventing the pressure roller body 2 from shifting during production, which would affect the paper production; by installing the guide boss 302 of the adjusting block 3 into the guide groove 102 on the frame 1, and being able to slide along the guide groove 102, the adjustment of the adjusting block 3 is guided, facilitating the adjustment of the adjusting block 3.

[0021] In the process of using this utility model, when it is necessary to adjust the pressure roller body 2, the drive source drives the adjustment block 3 to adjust along the guide groove 102 on the frame 1. The adjustment block 3 drives the pressure roller body 2 to move until the pressure roller body 2 is adjusted to the corresponding position. Then, the electromagnet 101 is energized. After the electromagnet 101 on the frame 1 is energized, it generates magnetism and attracts the magnet 303 on the adjustment block 3, further fixing the adjustment block 3.

[0022] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
