[0002] Vacuum rollers are key components in papermaking production lines. Their function is to absorb water from the pulp and form the paper. The greater the water absorption capacity of the vacuum roller, the less steam is needed in the subsequent drying section of papermaking. Due to their complex structure and large mass, vacuum rollers require reliable lubrication during operation.

[0003] Existing technologies require the use of lubrication tools to lubricate vacuum rollers, which is not convenient to operate and has poor practicality. Utility Model Content

[0004] The purpose of this invention is to provide a high-speed paper machine vacuum roll lubrication device 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-speed paper machine vacuum roll lubrication device, comprising a roll body, with a housing rotatably connected to the output shafts at both ends of the roll body, a rotating ring rotatably connected to each housing, a compression ring fixedly connected to each rotating ring, an oil tank fixedly connected to each housing adjacent to the rotating ring, a plurality of lifting rods slidably connected to the oil tank, a pressure block fixedly connected to one end of each lifting rod, a rubber block fixedly connected to the other end of each lifting rod, a spring fixedly connected to each rubber block, and a groove provided on the housing corresponding to the position of the rubber block.

[0006] Preferably, one end of the extrusion ring is set in an inclined state.

[0007] Preferably, each of the oil tanks has an oil inlet fixedly connected to its side wall, and each of the lifting rods has a rubber layer at the connection point with the oil tank.

[0008] Preferably, the rubber blocks are all annular in shape and are slidably connected inside the corresponding grooves.

[0009] Preferably, one end of each spring is fixedly connected to the inner wall of the oil tank, and one end of each lifting rod passes through the corresponding hollow position of the spring.

[0010] Compared with the prior art, the beneficial effects of this utility model are: by storing oil in the oil tank, the staff can save the step of taking tools, and can directly rotate the rotating ring to make the oil inside the oil tank flow to the shaft of the roller, thereby completing the oiling work of the roller. It is very convenient to use and has strong practicality. Attached Figure Description

[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-speed paper machine vacuum roller lubrication device, including a roller body 1, with a housing 2 rotatably connected to the output shafts at both ends of the roller body 1, a rotating ring 3 rotatably connected to the housing 2, a compression ring 4 fixedly connected to the rotating ring 3, an oil tank 5 fixedly connected to the housing 2 adjacent to the rotating ring 3, a plurality of lifting rods 6 slidably connected to the oil tank 5, a pressure block 7 fixedly connected to one end of each lifting rod 6, a rubber block 8 fixedly connected to the other end of each lifting rod 6, a spring 9 fixedly connected to each rubber block 8, and a groove 10 opened on the housing 2 corresponding to the position of the rubber block 8.

[0018] One end of the compression ring 4 is set at an inclined angle, which facilitates the compression of both ends of the pressure block 7. Oil inlets 11 are fixedly connected to the side walls of the oil tank 5. A rubber layer is provided at the connection between the lifting rod 6 and the oil tank 5. The oil inlets 11 facilitate the operator to add lubricating oil to the oil tank 5 at regular intervals. The rubber blocks 8 are all ring-shaped and are slidably connected to the inside of the corresponding grooves 10. The rubber blocks 8 can prevent the lubricating oil inside the oil tank 5 from flowing into the inside of the outer shell 2. One end of the spring 9 is fixedly connected to the inner wall of the oil tank 5. One end of the lifting rod 6 passes through the hollow position of the corresponding spring 9, which facilitates the spring 9 to drive the rubber blocks 8 to reset.

[0019] Specifically, when using this utility model, an external tool can be used to drive the compression ring 4 to rotate upward using the rotating ring 3. During the upward rotation of the compression ring 4, it will compress the first pressure block 7. At this time, the angled edge of one end of the compression ring 4 will compress the pressure block 7. The pressure block 7 will move away from the outer shell 2 under pressure. The movement of the pressure block 7 will also drive the lifting rod 6 to move. The movement of the lifting rod 6 will drive the rubber block 8 to move. The movement of the rubber block 8 will slowly separate from the trough 10. At the same time, the rubber block 8 will also compress and contract the spring 9. At this time, the oil inside the oil tank 5 will slowly... The lubricant enters through the trough 10 at the connection between the outer shell 2 and the output shaft of the roller 1, achieving a lubrication effect. Then, the continuously rotating extrusion ring 4 will squeeze the pressure block 7 one by one, moving it away from the outer shell 2. After that, all the rubber blocks 8 will separate from their corresponding troughs 10. At this time, the oil inside the oil tank 5 will flow through the trough 10 to the connection between the outer shell 2 and the output shaft of the roller 1. After the lubrication is completed, the rotating ring 3 can be reset. At this time, the spring 9 will drive the rubber block 8 to slowly retract into the trough 10, completing the lubrication work. It is easy to use. Just add an appropriate amount of lubricating oil to the oil tank 5 at regular intervals.

[0020] 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.
