Description

Technical Field

[0001] This utility model relates to the field of paper machine pressing technology, specifically a high wear-resistant paper machine press roll. Background Technology

[0002] As an important basic industry, papermaking products are widely used in culture, packaging, and daily life. With the continuous growth and diversification of social demand for paper, the papermaking industry is constantly pursuing efficient and high-quality production technologies to meet market demands and enhance corporate competitiveness. In the papermaking process, press rolls are one of the key components.

[0003] After prolonged use, current press rolls experience increased wear, resulting in decreased flatness and smoothness of the roll surface. This leads to uneven stress on the paper during the pressing process, causing quality problems such as inconsistent thickness and rough surface. To address this, we propose a highly wear-resistant paper machine press roll. Utility Model Content

[0004] The purpose of this invention is to provide a high-abrasion-resistant paper machine press roll to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-wear-resistant paper machine press roll, comprising a rotating shaft and a sealing block, wherein a roll body is fixedly connected to the middle of the rotating shaft wall, and mounting rings are fixedly connected to both sides of the rotating shaft wall near the roll body, wherein an air pump is fixedly connected to the wall of one of the mounting rings, and a connector is fixedly connected to the output end of the air pump, wherein a spiral channel is opened inside the roll body, and one end of the spiral channel extends through to the outer wall of the roll body, wherein a plurality of first oil outlet holes are opened through the roll body at one end of the spiral channel, and a plurality of second oil outlet holes are opened through the roll body at the other end of the spiral channel.

[0006] Preferably, couplings are provided at both ends of the shaft wall.

[0007] Preferably, the outer diameter of the connector is adapted to the inner diameter of the spiral channel.

[0008] Preferably, the diameter of the spiral channel gradually increases from one end to the other.

[0009] Preferably, a rubber ring is fixedly connected to the outer wall of the sealing block.

[0010] Compared with the prior art, the beneficial effects of this utility model are: by setting a gradually increasing spiral channel, in conjunction with the first oil outlet and the second oil outlet, the pressure loss can be compensated, so that the lubricating oil can reach each point more evenly, reducing the wear of the press roller and thus improving the service life of the press roller. Furthermore, by setting the air pump and the connector, on the one hand, the lubricating oil can be distributed to the spiral channel path, and on the other hand, the lubricating oil inside the spiral channel can be cleaned during the maintenance of the roller body.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 This utility model provides a technical solution: a high wear-resistant paper machine press roll, including a rotating shaft 1 and a sealing block 16. A roll body 11 is fixedly connected to the middle of the shaft wall of the rotating shaft 1. Mounting rings 13 are fixedly connected to both sides of the shaft wall of the rotating shaft 1 near the roll body 11. An air pump 14 is fixedly connected to the ring wall of one of the mounting rings 13. A connector 15 is fixedly connected to the output end of the air pump 14. A spiral channel 101 is opened inside the roll body 11, and one end of the spiral channel 101 extends through to the outer wall of the roll body 11. A plurality of first oil outlet holes 102 are opened through the roll body 11 at one end of the spiral channel 101, and a plurality of second oil outlet holes 103 are opened through the roll body 11 at the other end of the spiral channel 101.

[0018] Furthermore, couplings 12 are provided at both ends of the shaft wall of the rotating shaft 1, through which the roller body 11 can be installed on the pressing equipment.

[0019] Furthermore, the outer diameter of the connector 15 is compatible with the inner diameter of the spiral channel 101, so that the connector 15 can be snapped into the inlet of the spiral channel 101.

[0020] Furthermore, the diameter of the spiral passage 101 gradually increases from one end to the other. The gradually increasing spiral passage 101 compensates for pressure loss, allowing the lubricating oil to reach each point more evenly.

[0021] Furthermore, a rubber ring 17 is fixedly connected to the outer wall of the sealing block 16, which can seal the spiral channel 101.

[0022] Specifically, when using this utility model, the roller body 11 can first be removed from the pressing equipment via the coupling 12, then the sealing block 16 is pulled out, and then lubricating oil is injected into the spiral channel 101. Then, the connector 15 is connected to the inlet end of the spiral channel 101, and the air pump 14 is started to inject gas into the spiral channel 101 through the connector 15, so that the lubricating oil is distributed throughout the entire spiral channel 101 path. Then, the roller body 11 can be installed on the pressing equipment via the coupling 12. When the roller body 11 rotates, the lubricating oil will flow out through several first oil outlet holes 102 and second oil outlet holes 103, and gradually increase the spiral channel 101 to compensate for pressure loss, so that the lubricating oil can reach each point more evenly, so that the roller wall of the roller body 11 can be covered with lubricating oil, reducing the wear of the roller body 11, thereby improving the service life of the pressing roller.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
