[0003] When its roll is in use, through continuous rolling and extrusion, the moisture in the pulp is squeezed out. Then, when the existing technology is in use, due to the wet surface of the pulp, when the roll body squeezes it, some pulp will adhere to the outer surface of the roll body. And the pulp adhering to the roll body surface, on the one hand, will cause indentations on the pulp surface, affecting the quality of the pulp after extrusion. On the other hand, the pulp adhering to the roll body surface will adhere more tightly to the roll body after drying for a certain time, resulting in difficulty in subsequent cleaning. Therefore, we propose a roll structure of a paper machine to solve the problems raised above. Summary of the Utility Model

[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1, as Figures 1-4 shown, a structure of a machine roll for a paper machine includes an overall structure 1 and a support structure 2. The support structure 2 is located at the front and rear positions on both sides of the bottom of the overall structure 1. The overall structure 1 includes a bottom plate 101 and a fixed plate 102. A roll body 106 is rotatably connected to the relative side of the two fixed plates 102 near the top position. A first pulley 110 is fixedly connected to the outer surface of one side of the roll body 106. A servo motor 108 is fixedly installed on the outer surface of one side of one of the fixed plates 102 near the bottom position. The output end of the servo motor 108 is fixedly connected to a second pulley 103. A brush plate 113 is rotatably connected to the relative side of the two fixed plates 102 near the rear position of the top. A third pulley 111 is fixedly connected to the center of the outer surface of one side of the brush plate 113. The inner surface centers of the first pulley 110, the second pulley 103 and the third pulley 111 are slidably connected with a belt body 105. A connecting plate 117 is fixedly connected to the front outer surface of the fixed plate 102 near the top position.

[0024] The effect achieved by the entire Example 1 is that, as Figure 1 and Figure 2 shown, subsequently through the mutual cooperation of the servo motor 108, the first pulley 110, the second pulley 103, the belt body 105 and the third pulley 111, the roller 106 and the brush plate 113 can rotate normally. Then, the brush plate 113 can clean the pulp on the roller 106, thereby playing a role in preliminary cleaning. Subsequently, through the setting of the scraper 114, the surface of the roller 106 can be cleaned for the second time. And as Figure 1 and Figure 3 shown, part of the scraper 114 is chamfered, so it will not damage the surface of the roller 106 when scraping.

[0025] Example 2, as Figures 1-4 shown, on both sides of the front and rear positions of the top of the bottom plate 101, cylinders 119 are fixedly connected. A connecting rod 120 is slidably connected to the inner wall of the cylinder 119 near the center. The top end face of the connecting rod 120 is fixedly connected to the bottom surface of the fixing plate 102. An electric push rod 118 is fixedly installed at the center of the inner bottom of the cylinder 119. The extending end of the electric push rod 118 is fixedly connected to the bottom surface of the connecting rod 120. A number of uniformly distributed circular grooves 107 are formed on the outer surface of the roller 106. Slide rods 115 are fixedly connected to both sides of the inner surface of the connecting plate 117. Compression springs 116 are sleeved on the outer surfaces of the slide rods 115. The extending ends of the slide rods 115 are fixedly connected to the scraper 114. The outer surfaces of the scraper 114 and the brush plate 113 are slidably connected to the outer surface of the roller 106. Card slots 109 are formed on the front and rear outer surfaces of the fixing plate 102 near the center. A clamping block 104 is slidably connected to the center of the inner wall of the card slot 109. A collecting box 112 is fixedly connected to the opposite sides of the two clamping blocks 104. The support structure 2 includes a fixing rod 201. A support foot 202 is fixedly connected to the bottom end face of the fixing rod 201. The top end face of the fixing rod 201 is fixedly connected to the bottom surface of the bottom plate 101.

[0026] The effect achieved by the entire Example 2 is that subsequently when the electric push rod 118 extends or retracts, it will drive the connecting rod 120 to move up and down in the cylinder 119, and the connecting rod 120 can drive the fixing plate 102 and the roller 106 to move up and down, so that the height of the roller 106 can be adjusted to facilitate subsequent adjustment according to different requirements. Through the setting of the card slot 109 and the clamping block 104, it is convenient for the user to disassemble and assemble the collecting box 112. And through the setting of the fixing rod 201 and the support foot 202, the overall stability can be improved.

[0027] Working principle: When it is necessary to extrude the pulp, the pulp is continuously conveyed below the roller body 106. Under the extrusion of the roller body 106, the water in the pulp is squeezed out. The roller body 106 and the fixed plate 102 have completed the height adjustment through the cooperation of the electric push rod 118 and the connecting rod 120. Since the surface of the pulp is wet, part of it will adhere to the surface of the roller body 106. Then, while the roller body 106, the second pulley 103 and the first pulley 110 can rotate, the third pulley 111 can be driven to rotate together through the belt body 105, so that the brush plate 113 can rotate normally, thereby realizing the preliminary cleaning of the pulp on the surface of the roller body 106. The scraper 114 uses the expansion force of the compression spring 116 to scrape forcefully against the roller body 106, realizing the secondary cleaning of the roller body 106, avoiding the remaining pulp on the roller body 106, and the cleaned pulp can directly fall into the collection box 112 for subsequent users to process it.

[0028] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
