Description

Technical Field

[0001] This utility model specifically relates to a vacuum roller with a stable supporting structure. Background Technology

[0002] Vacuum rollers typically consist of a robust outer shell, an internal chamber, a vacuum interface, and a roller surface. Their working principle involves an external vacuum pump evacuating the internal chamber through the vacuum interface. This gradually removes air from the chamber, causing the internal pressure to drop below the external atmospheric pressure. Based on the principle of pressure difference, outside air tends to flow into the chamber. However, due to the obstruction of the roller surface, adsorption occurs when the roller surface comes into contact with external substances. Vacuum rollers are widely used in the paper, printing, packaging, and textile industries.

[0003] Traditional vacuum rollers typically employ single-point support or simple double-sided symmetrical support. When the vacuum roller is running at high speed, due to the combined forces of the roller's own weight, external material pressure, and vacuum suction, this single-point or simple double-sided symmetrical support can easily lead to stress concentration at the stress points, thereby accelerating the wear of the roller's surface and internal structure and shortening the service life of the vacuum roller.

[0004] Therefore, it is necessary to invent a vacuum roller with a stable supporting structure to solve the above problems. Utility Model Content

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-3 The vacuum roller shown has a stable support structure, including support structures installed at the bottom of both ends of the vacuum roller body 1.

[0028] Specifically, the vacuum roller body 1 includes a roller body 11, and the two ends of the roller body 11 are connected to the drive device 13 through the mounting frame 12;

[0029] Reference Figure 2-3 The support structure includes two sets of support components 2, and a support bridge 3 is installed between the two sets of support components 2. The support bridge 3 is placed at the bottom of the vacuum roller body 1, and the support components 2 are supported at the mounting frame 12.

[0030] In this embodiment, both ends of the roller 11 are passed through the mounting frame 12 to ensure that the roller 11 can rotate freely within the mounting frame 12. Then, both ends of the roller 11 are connected to the drive device 13, so that the drive device 13 can provide power for the rotation of the roller 11.

[0031] Specifically, the support component 2 includes a support base 21, a support reinforcement platform 22 extending upward from the top of the support base 21, a support column 23 at the top of the support reinforcement platform 22, an arc-shaped fixing groove 24 at the top of the support column 23, the arc-shaped fixing groove 24 corresponding to the mounting bracket 12, and a fixing bracket 25 at the top of the support column 23, which is located at the top of the mounting bracket 12.

[0032] Specifically, the part of the support base 21 that connects to the support reinforcement platform 22 is set as an inclined surface, and multiple reinforcing ribs 26 are provided between the four corners of the support reinforcement platform 22 and the four outer corners of the support column 23.

[0033] Specifically, the fixing bracket 25 is arc-shaped, and its inner shape matches the outer wall shape of the mounting bracket 12, which cooperates with the arc-shaped fixing groove 24 to fix the mounting bracket 12.

[0034] Specifically, the connection between the fixing frame 25 and the support column 23 is provided with a docking mounting plate 27, and the docking mounting plates 27 on the upper and lower sides are the same size and are fixed by multiple bolts 28.

[0035] In this embodiment, for each support component 2, the support base 21 is first placed in a suitable position. Since the connection between the support base 21 and the support reinforcement platform 22 is designed as a slope, the slope design makes the connection between the support reinforcement platform 22 and the support base 21 more stable when installing the support reinforcement platform 22. The slope can increase the contact area between the two, and when subjected to external force, the slope can disperse stress and reduce the situation of excessive local pressure.

[0036] Specifically, multiple reinforcing ribs 26 are installed between the four corners of the supporting platform 22 and the four outer corners of the supporting column 23. These reinforcing ribs 26 can be fixed by welding or bolting. The function of the reinforcing ribs 26 is to enhance the connection strength between the supporting platform 22 and the supporting column 23, preventing deformation or breakage between them when subjected to large loads.

[0037] Specifically, at the top of the support column 23, the arc-shaped fixing groove 24 is aligned with the mounting bracket 12, and then the fixing bracket 25 is installed on top of the mounting bracket 12. The fixing bracket 25 is arc-shaped, and its inner shape matches the outer wall shape of the mounting bracket 12, cooperating with the arc-shaped fixing groove 24 to fix the mounting bracket 12. At the connection between the fixing bracket 25 and the support column 23, they are fixed together using multiple bolts 28 through mating mounting plates 27 of the same size on both the upper and lower sides.

[0038] Specifically, the support bridge 3 is fixed inside the two sets of support columns 23, and its shape matches the shape of the outer wall of the roller body 11. A distance of 15cm is left between the support bridge 3 and the outer wall of the roller body 11.

[0039] Specifically, the lowest surface of the support bridge 3 exceeds the highest connection point of the reinforcing rib 26.

[0040] In this embodiment, the support bridge 3 is installed inside the two sets of support columns 23, ensuring that its shape matches the shape of the outer wall of the roller body 11, and leaving a 15cm distance between the support bridge 3 and the outer wall of the roller body 11. During installation, care should be taken to ensure that the lowest surface of the support bridge 3 exceeds the highest connection point of the reinforcing rib 26 to avoid collision between the two during installation or operation.

[0041] In this embodiment, the inclined surface design on the support base 21 makes the support reinforcement platform 22 more stable after installation. When the vacuum roller is subjected to various forces during operation, the inclined surface can effectively transfer these forces to the base and disperse them. If it is vertical pressure, the inclined surface can convert part of the pressure into a horizontal component, thereby reducing the single-point pressure on the support base 21 in the vertical direction and preventing the support base 21 from sinking or being damaged locally.

[0042] Specifically, multiple reinforcing ribs 26 significantly enhance the connection strength between the supporting platform 22 and the supporting column 23. During the operation of the vacuum roller, when the supporting column 23 is subjected to pressure from above, the reinforcing ribs 26 prevent the supporting column 23 from tilting or shifting relative to the supporting platform 22. In a high-speed rotating vacuum roller, without the reinforcing ribs 26, the supporting column 23 may gradually loosen due to vibration, while the reinforcing ribs 26 effectively suppress this loosening tendency, ensuring the stability of the entire support structure.

[0043] Specifically, the two sets of support components 2 and the intermediate support bridge 3 together form a stable support system. The support components 2 support the mounting frame 12 from both ends, while the support bridge 3 provides auxiliary support to the roller body 11 from below. This structure allows the vacuum roller to remain stable during operation, reducing swaying and vibration. In some industrial applications where the flatness of the roller surface is critical, this stable support structure ensures that the surface of the roller body 11 maintains a uniform pressure distribution, thereby improving product quality.

[0044] In this embodiment, the fixing frame 25 engages with the arc-shaped fixing groove 24 at the top of the support column 23 to firmly fix the mounting frame 12 onto the support column 23. The arc-shaped inner side of the fixing frame 25 matches the outer wall shape of the mounting frame 12, and this tight fit prevents the mounting frame 12 from shifting in the horizontal and vertical directions. When the vacuum roller is subjected to lateral force, the mounting frame 12 will not easily shift, thereby ensuring the normal operation of the roller body 11.

[0045] In this embodiment, the mating mounting plate 27 of the connection between the fixing frame 25 and the support column 23 is fixed by multiple bolts 28. This fixing method makes the connection between the fixing frame 25 and the support column 23 more robust and reliable. The even distribution of the bolts 28 can make the connection part evenly stressed, and during long-term operation, even if it is affected by external forces such as vibration, it is not easy for the bolts to loosen or the connection to fail.

[0046] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
