Description

TECHNICAL FIELD

[0001] The utility model belongs to photovoltaic glass processing equipment technical field relates to a kind of annealing roll support structure of anti-positioning. BACKGROUND

[0002] Due to the particularity of photovoltaic glass production, weather changes and brick replacement have a greater impact on the temperature of the annealing furnace. The annealing roller of the annealing furnace is affected by temperature changes. The bearing of the annealing roller expands and contracts with heat. The locking sleeve loosens. The bearing seat is forced to move forward, which may cause the roller to fall off and cause the annealing roller to shift position, resulting in glass falling off the board, seriously affecting production and causing losses. It often occurs during sudden changes in weather temperature and machine replacement. And part of the roller is not obvious, so it is not easy to find out, which leads to sudden accidents. Due to the inherent reasons of production, it is difficult to make timely adjustments to the shift position. To prevent the roller from falling off and affecting production, a steel wire rope is installed on the driven side of the annealing roller. When the annealing roller shifts position and moves outward, the steel wire rope stops the annealing roller. A steel wire rope is installed on the bearing seat of the annealing roller. When the shift position is reached, the steel wire rope stops the annealing roller to prevent it from falling off. But the installation process of the steel wire rope is troublesome and inconvenient for subsequent repair work, and it is easy to cause material waste. SUMMARY

[0003] The utility model aims at the above-mentioned problems existing in the prior art, and provides an annealing roller support structure for preventing position shifting. The technical problem to be solved by the utility model is how to prevent the annealing roller from detaching from the support due to thermal expansion and contraction.

[0004] The utility model can be realized by the following technical scheme: an annealing roller support structure for preventing position shifting, characterized by comprising a bearing seat, a bearing and a roller body. The outer ring of the bearing is connected to the inner hole wall of the bearing seat through a spline. One end of the roller body is fixed in the inner ring of the bearing. Two ends of the outer ring of the bearing are respectively provided with a compression spring between the bearing seat.

[0005] Further, the inner hole of the bearing seat is threadedly connected with two limiting sleeves respectively located at the two ends of the outer ring of the bearing. The two ends of the compression spring are respectively abutted between the outer ring of the bearing and the limiting sleeves. The limiting sleeves facilitate the support of the compression spring and also limit the bearing to prevent it from falling off under a large external force.

[0006] In this scheme, the non-driving end of the annealing roller is set as a movable end. The spline structure between the outer ring of the bearing and the inner hole of the bearing seat allows the bearing as a whole to move axially in the inner hole of the bearing seat. The compression spring realizes the sliding limit of the bearing in the inner hole of the bearing seat and compensates for the length change of the roller body caused by thermal expansion and contraction, thereby preventing the roller body from falling off. It also greatly reduces the stress concentration caused by thermal expansion and contraction of the roller body, which provides good protection for the annealing roller. BRIEF DESCRIPTION OF DRAWINGS

[0007] Figure 1 This is a schematic diagram of the anti-displacement annealing roller support structure.

[0008] In the diagram, 1 is the bearing housing; 2 is the bearing; 3 is the roller body; 4 is the compression spring; and 5 is the limit sleeve. Detailed Implementation

[0009] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0010] like Figure 1 The annealing roller support structure shown includes a bearing housing 1, a bearing 2, and a roller body 3. The outer ring of the bearing 2 is connected to the inner wall of the bearing housing 1 by a spline. One end of the roller body 3 is fixed inside the inner ring of the bearing 2. A compression spring 4 is provided between the two ends of the outer ring of the bearing 2 and the bearing housing 1, respectively.

[0011] The bearing housing 1 has two limiting sleeves 5 located at both ends of the outer ring of the bearing 2 via internal thread connection. The two ends of the compression spring 4 abut against the outer ring of the bearing 2 and the limiting sleeves 5, respectively. The limiting sleeves 5 are provided to facilitate the support of the compression spring 4 and to restrict the bearing 2, preventing it from falling off under large external forces.

[0012] In this solution, the non-drive end of the annealing roller is set as a movable end. Through the spline structure between the outer ring of the bearing 2 and the inner hole of the bearing seat 1, the bearing 2 can be axially moved within the inner hole of the bearing seat 1. The sliding limit of the bearing 2 within the inner hole of the bearing seat 1 is achieved by the compression spring 4, and the length change of the roller body 3 caused by thermal expansion and contraction is compensated. As a result, the textile roller body 3 falls off, and the stress concentration caused by thermal expansion and contraction of the roller body 3 is greatly reduced, which plays a good protective role for the annealing roller.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
