Abstract
Description
Technical Field
[0001] This utility model belongs to the field of tempered glass, specifically relating to a rope winding method for the cooling section of a glass tempering furnace. Background Technology
[0002] Currently, glass tempering furnaces on the market typically include an loading platform, a heating section, a cooling section, and an unloading platform. Glass sheets are carried by conveyor rollers sequentially through these sections. The glass to be processed is loaded onto the loading platform, heated at high temperatures in the heating section, tempered and cooled by airflow from upper and lower bellows in the cooling section, and finally unloaded at the unloading platform. During the cooling section, rapid cooling by airflow from both above and below is necessary to generate internal stress and achieve the tempering effect. In the cooling section, especially the air-blowing tempering section, because the glass it carries still has a very high surface temperature (around 600°C) after being discharged from the heating section, a steel pipe or ceramic roller structure is typically used as the main conveyor, with high-temperature refractory rope wrapped around its exterior.
[0003] The existing roller conveyor rope winding cross section is rectangular, as shown in the attached figure. Figure 2 As shown, the transverse width D is 8-15mm, and the thickness H is 1-4mm. A rope is wound around the roller conveyor, and the glass is supported on the rope. The contact area between the glass and the rope is positively correlated with its transverse width D. However, when the rope comes into contact with the high-temperature glass, it also rapidly absorbs heat from the glass. This results in a difference in the actual temperature drop rate between the contact surface and the non-contact surface, leading to different tempering stress values on the lower surface of the glass compared to the contact surface. This difference in stress values creates wind marks, which in turn affects the flatness of the glass. All of these issues require improvement. Utility Model Content
[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a roller winding rope in the cooling section of a glass tempering furnace that can reduce stress spots on glass.
[0005] To achieve the above objectives, the present invention provides the following technical solution.
[0006] A roller winding rope for the cooling section of a glass tempering furnace is provided. The winding rope is long and has a flat bottom and a protrusion that are tightly fastened together. The protrusion is located above the flat bottom. The flat bottom is wound and in contact with the roller. The protrusion is in contact with the glass and carries the glass. The lateral width D2 of the protrusion is smaller than the lateral width D1 of the flat bottom, where D2 is 2-5mm.
[0007] Furthermore, the cross-section of the rope is convex, with the protruding part located in the middle of the flat bottom.
[0008] Furthermore, the cross-section of the rope is L-shaped, with its protruding part located at one end of the flat bottom.
[0009] Further, D1 is 8-15mm, and D2 is 2-5mm.
[0010] Further, the thickness H1 of the flat bottom part is 1-4mm, and the thickness H2 of the convex part is 1-4mm.
[0011] Further, the cross section of the rope is an arc surface, and the convex part of the arc surface is an arc.
[0012] Further, the transverse width D1 of the flat bottom part is 3-12mm, and the overall thickness H of the rope is 1-4mm.
[0013] Further, the flat bottom part and the convex part are integrally woven and formed.
[0014] Compared with the prior art, the roller rope in the utility model is provided with a convex part, the width of the convex part is narrower than the width of the bottom part of the prior rope, the glass only contacts with the convex part, so that the direct contact area of the rope and the glass is reduced, the heat absorption effect of the rope is reduced, the temperature difference between the contact surface and the non-contact surface of the glass and the rope is reduced, the stress spot of the glass caused by the contact of the rope is reduced, the flatness of the glass is better, and the glass quality is improved. Meanwhile, the bottom part of the roller rope in the utility model has a flat bottom part, so that the winding strength of the roller rope and the roller is ensured, that is, the roller rope in the utility model has the heat insulation and heat absorption reduction effects without affecting the winding strength of the roller, and the design is ingenious and practical.

[0020] In order to make the shape, structure and characteristics of the utility model better understood, the following preferred embodiments will be enumerated and described in detail in combination with the drawings. EMBODIMENT
[0021] As Figure 1As shown in the figure, the rope 1 is wound on the roller 2, the rope 1 is in contact with the lower surface of the glass and bears the glass to protect the glass from bumping, and the glass and the roller are heat insulated. As shown in the figure, Figure 2 As shown in the figure, the cross section of the rope 1 is rectangular, the transverse width D is 8-15mm, and the thickness H is 1-4mm. Therefore, the transverse contact length of the rope 1 with the roller and the glass is the transverse width D. When the rope is in contact with the high-temperature glass, it will also absorb the heat on the glass, which will cause the actual cooling effect of the contact surface and the non-contact surface of the glass and the rope to be different, and finally cause the lower surface of the glass to generate more stress spots due to the contact with the rope, affecting the flatness of the glass.
[0022] Therefore, the present embodiment provides a new type of roller rope for the cooling section of the glass tempering furnace, as shown in the figure, Figure 3 The rope is in the shape of a long strip, has a flat bottom part 11 and a protruding part 12, and the flat bottom part 11 and the protruding part 12 are integrally woven. The flat bottom part 11 is also a longitudinal long strip, and the protruding part 12 can be a long strip or a protruding block. The protruding part 12 is located above the flat bottom part 11, the flat bottom part 11 is in contact with the roller 2, and the protruding part 12 is in contact with the glass 3 and bears the glass.
[0023] In the present embodiment, the transverse width D2 of the protruding part 12 is smaller than the transverse width D1 of the flat bottom part 11. Specifically, D1 is 8-15mm, and D2 is 2-5mm. The width of the flat bottom part 11 can ensure the winding strength of the roller rope and the roller. The protruding part 12 can support the glass to avoid the glass collapsing the protruding part 12 and losing the effect of reducing the absorption of the glass heat.
[0024] In the present embodiment, the cross section of the rope 1 is convex, and the protruding part 12 is located in the middle of the flat bottom part 11. In this way, the glass can achieve better balance on the rope.
[0025] In addition, the thickness H1 of the flat bottom part 11 is 1-4mm, and the thickness H2 of the protruding part 12 is 1-4mm. In this way, the glass can obtain sufficient support strength. Embodiment
[0026] As shown in the figure, Figure 4 Compared with the first embodiment, the cross section of the rope 1 in the present embodiment is L-shaped, and the protruding part 12 is located at one end of the flat bottom part 11. It also has the effects of support and heat absorption reduction. Embodiment
[0027] As shown in the figure, Figure 5As shown, compared with the first and second embodiments, the cross section of the rope 1 in the third embodiment is an arcuate surface, and the convex portion 12 is an arc. The width D1 of the flat bottom portion 11 is 3-12 mm, and the overall thickness H of the rope 1 is 1-4 mm. The width D2 of the convex portion 12 in the figure is the schematic width after the arc top of the glass pressing convex portion 12, and the size is also limited within 2-5 mm, which is also lower than the contact width of 8-15 mm in the prior art. The arcuate rope is more convenient for weaving and forming.
[0028] The above description of the present application is illustrative rather than limiting and many modifications, changes, and equivalents will become apparent to those skilled in the art, which fall within the spirit and scope of the claims.
