[0026] The specific implementation of the utility model is further described in detail below in conjunction with the drawings and embodiments.

[0027] The airbags in the paper machine inflation shaft cannot be restored after being deflated due to the bulging state of the airbags in the long-term use. The length of an inflation shaft is 155cm. When in use, the aluminum tube is put on the inflation shaft to roll up the paper roll. The length of the aluminum tube is about 131cm. During the paper roll rolling process, the aluminum tube is usually placed in the middle of the inflation shaft. There are about 9cm of airbags on the left and right that cannot be covered by the aluminum tube, resulting in the airbags that cannot be covered being in a bulging state when inflated, shortening the service life of the inflation shaft.

[0028] For example, Figure 1 As shown, the paper reel tube 20 is sleeved on the air shaft 10 , and the axial length of the paper reel tube 20 is smaller than the length of the air shaft 10 , resulting in a partial area of ​​the air shaft 10 being exposed through the paper reel tube 20 .

[0029] Based on this, the utility model provides a paper roll winding device for a papermaking machine, such as Figure 1 As shown, the paper roll winding device for a paper machine comprises an air expansion shaft 10, a paper reel tube 20 and an air expansion shaft protective sleeve 30. The paper reel tube 20 can be sleeved on the air expansion shaft 10, and the air expansion shaft 10 expands to fix the paper reel tube 20. The paper reel tube 20 is used to roll up stone paper. The axial length of the paper reel tube 20 is less than the axial length of the air expansion shaft 10, so that a part of the air expansion shaft 10 is exposed through the paper reel tube 20. The air expansion shaft protective sleeve 30 is used to cover the area of ​​the air expansion shaft 10 exposed through the paper reel tube 20.

[0030] The paper roll winding device for a papermaking machine provided in this embodiment is provided with an air inflation shaft protection sleeve 30, which can cover the area of ​​the air inflation shaft 10 exposed through the paper reel tube 20, thereby protecting the air inflation shaft 10, avoiding the problem of bulging of the air bag of the air inflation shaft 10 that cannot be covered by the paper reel tube 20, and extending the service life of the air inflation shaft 10.

[0031] In one embodiment, if Figure 2 As shown, the paper reel tube 20 is sleeved on the middle part of the air shaft 10, and the two end regions of the air shaft 10 are exposed through the paper reel tube 20. Two air shaft protection sleeves 30 are provided, and the two air shaft protection sleeves 30 respectively cover the two end regions of the air shaft 10, thereby ensuring the uniformity of the force of the paper reel tube 20 and the air shaft protection sleeve 30.

[0032] In one embodiment, if Figure 3 As shown, the inner diameter of the paper roll tube 20 is equal to the inner diameter of the air shaft protective sleeve 30, thereby ensuring that after the air shaft 10 is expanded, the area exposed by the paper roll tube 20 can form a good fit with the air shaft protective sleeve 30, thereby improving the protective effect of the air shaft protective sleeve 30 on the air shaft 10.

[0033] In one embodiment, if Figure 4 As shown, the end face of the inflatable shaft protective sleeve 30 facing one end of the paper winding tube 20 is provided with a first annular protrusion structure 31, and the outer diameter of the paper winding tube 20 is adapted to the inner diameter of the first annular protrusion structure 31, so that the paper winding tube 20 can be inserted into the first annular protrusion structure 31, thereby achieving good positioning of the paper winding tube 20.

[0034] In one embodiment, the axial length of the inflatable shaft protective sleeve 30 is adjustable, so that the inflatable shaft protective sleeve 30 can be adapted to the paper winding tube 20 with different axial lengths.

[0035] Exemplarily, the inflatable shaft protection sleeve 30 is a telescopic tube structure, and the axial length of the inflatable shaft protection sleeve 30 is adjusted by telescoping the telescopic tube structure.

[0036] In another embodiment, if Figure 5 As shown, the air shaft protective cover 30 is a multi-stage structure, and the air shaft protective cover 30 includes a plurality of protective cover units, and the adjacent protective cover units are detachably connected. In this way, different paper roll tubes 20 can be adapted by adjusting the number of protective cover units mounted on the air shaft 10.

[0037] In one embodiment, the multiple protective cover units include a first protective cover unit 32 located at one end away from the paper rolling tube 20 and at least two second protective cover units 33, the first protective cover unit 32 is provided with a second annular protruding structure 321 on the end surface facing the paper rolling tube 20, the second protective cover unit 33 is provided with a third annular protruding structure 331 on the end surface facing the first protective cover unit 32, and the second protective cover unit 33 is provided with a fourth annular protruding structure 332 on the end surface facing the paper rolling tube 20, the inner diameter of the second annular protruding structure 321 is adapted to the outer diameter of the third annular protruding structure 331, the inner diameter of the third annular protruding structure 331 is the same as the inner diameter of the paper rolling tube 20, and the inner diameter of the fourth annular protruding structure 332 is adapted to both the outer diameter of the third annular protruding structure 331 and the outer diameter of the paper rolling tube 20. In this way, while adjusting the number of the second protective sleeve units 33 to adapt to the paper reel tubes 20 of different axial lengths, the positioning of the paper reel tube 20 is facilitated, for example, Figure 6 As shown, when one second protective cover unit 33 is reduced, the paper winding tube 20 can also be positioned.

[0038] The above implementation modes are only used to illustrate the present invention, but not to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The scope of patent protection of the present invention should be limited by the claims.
