Description

Technical Field

[0001] The utility model belongs to the technical field of glass production machinery, and in particular relates to a driving roller of a mesh belt annealing furnace for glass products. Background Art

[0002] The annealing furnace is a mechanical equipment specially used for manufacturing glass bottles. Its main purpose is to perform stress relief annealing on glass bottles that have not yet cooled down to ensure their quality and performance. The mesh belt in the annealing furnace carries dozens of tons of glass bottles, so the driving capacity and quality of the mesh belt transmission roller directly determine the performance and service life of the annealing furnace.

[0003] Traditional drive rollers have some defects. First, there are multiple steps on the transmission shaft, which will cause stress concentration and make the strength of the shaft uneven. In the process of welding the transmission shaft, micro cracks are easily generated, which will accelerate the fatigue fracture of the transmission shaft.

[0004] In addition, the transmission shaft also has the problem of axial movement. When the transmission shaft is squeezed with surrounding parts, it will cause radial force overload, which will lead to the fracture of the transmission shaft. In addition, the rubber layer has a small contact area with the roller and is easy to peel off, which will affect the stability and efficiency of the transmission. Utility Model Content

DETAILED DESCRIPTION

[0024] Figures 1 to 4 It is the best embodiment of the utility model, and the following Figures 1 to 4 The utility model is further described.

[0025] like Figure 1~2 As shown, the utility model is a driving roller of a glass product mesh belt annealing furnace, comprising a roller 1 and a rotating shaft, characterized in that: support rings 4 are respectively provided on both sides of the roller 1, the roller 1 is sleeved on the support rings 4, the rotating shaft comprises a transmission shaft 9 and a tail shaft 12, sleeves 11 are respectively sleeved on the transmission shaft 9 and the tail shaft 12, the transmission shaft 9 and the tail shaft 12 are respectively interference fit with the sleeve 11, the support ring 4 is fixed to the sleeve 11 by welding, the support ring 4 is arranged perpendicular to the length direction of the rotating shaft, and the roller 1 rotates synchronously with the rotating shaft.

[0026] In this embodiment, the inner diameter of the support ring 4 is the same as the outer diameter of the sleeve 11, and the outer diameter of the support ring 4 is the same as the inner diameter of the roller 1. A plurality of ribs 14 are evenly welded on the support ring 4, one end of the rib 14 is welded to the sleeve 11, and the other end is welded to the inner wall of the roller 1. The ribs 14 can enhance the support strength of the support ring 4. The support ring 4 is also provided with air holes to facilitate the discharge of gas generated during the heating and cooling of welding.

[0027] An inner ring 2 is also provided between the support rings in the roller 1, and a connecting pipe 3 is also sleeved between the sleeve 11 of the transmission shaft and the tail shaft. The inner ring 2 and the connecting pipe 3 are fixed by welding, and the inner ring 2 is arranged perpendicular to the length direction of the rotating shaft. In this embodiment, two inner rings 2 are provided between the two support rings 4, and the inner rings 2 play a role in increasing the strength of the roller 1. The provision of the sleeve 11 enables the support ring 4 to be indirectly connected to the rotating shaft, avoiding microcracks caused by direct welding on the rotating shaft, and reducing the possibility of the rotating shaft breaking.

[0028] Combination Figure 3 A thread 15 is provided on the outer wall of the roller 1. In this embodiment, the angle of the thread 15 is set to 60°. A rubber layer 10 is sleeved on the outer wall of the roller 1. The thread 15 on the outer wall of the roller 1 increases the contact area between the rubber layer 10 and the roller 1, making it difficult for the rubber layer 10 to peel off.

[0029] Combination Figure 4The transmission shaft 9 is arranged through the first seat bearing 8. The inner positioning sleeve 17 and the outer positioning sleeve 16 are respectively arranged at the positions on both sides of the first seat bearing 8 that contact the transmission shaft 9, which play the role of pressing the transmission shaft 9 to prevent the transmission shaft 9 from shaking up and down. The end of the transmission shaft 9 is connected to the sprocket 5. In this embodiment, a flat key 6 is provided on the sprocket 5, and the transmission shaft 9 is installed in the sprocket 5 through the flat key 6.

[0032] In order to further improve the performance of the transmission roller, the utility model sets a rib plate 14 on the support ring 4 and evenly welds it on the support ring 4. This design can not only strengthen the support strength of the support ring 4, but also increase the overall rigidity of the transmission roller, making it more durable and stable. At the same time, the gas discharge generated during the welding process is also effectively handled, and the air holes set on the support ring 4 ensure the smooth progress of the welding process.

[0033] The utility model solves many problems existing in traditional drive rollers, including welding weaknesses, axial movement, and peeling of the rubber layer 10, by improving the design and optimizing the structure.
