Description

Technical Field

[0001] The utility model relates to a glass tempering transmission wheel and a transmission device. Background Art

[0002] Physical tempering of glass deep processing is the process of heating glass products to a temperature close to the softening point and then quickly sending them into a cooling device for uniform cooling to form a uniform stress layer inside and outside the glass. After the glass is tempered, due to the uneven heating and cooling during the tempering process, different stress distributions will be generated on the glass plate surface. When tempered glass is placed under polarized light, the color and light and dark changes in different areas on the glass plate surface can be observed. This is the stress spot of tempered glass. The tempering of bent tempered glass is the process of quickly sending the glass into an arc bending device after heating is completed, and quickly cooling it after forming an arc in the arc bending device.

[0003] The cooling device of the soft-shaft bent tempered glass realizes the arc forming and glass transmission through a deformable soft transmission shaft. The transmission shaft needs to be interspersed with multiple bearings to realize the arc forming. Therefore, the soft transmission shaft cannot directly contact and transmit the glass. It is necessary to add a cylindrical transmission wheel to the soft transmission shaft to contact and transmit the glass. However, the continuous contact between the cylindrical transmission wheel and the lower surface of the glass will cause the cooling effect of this area to be inconsistent with that of other areas, resulting in differences in glass density and stress, thereby producing striped stress spots.

[0032] Example 1

[0033] See also Figures 1 to 5 The glass tempering transmission wheel shown in the figure includes a wheel body 1, which is cylindrical and has a center hole 11 for the transmission shaft 7 to pass through. The extension direction of the center hole 11 is consistent with the extension direction of the wheel body 1. A plurality of blades 5 are arranged on the outer peripheral surface of the wheel body 1. The plurality of blades 5 are arranged around the outer periphery of the wheel body 1, and the plurality of blades 5 are arranged at intervals. The blades 5 are arranged obliquely, and the projections of two adjacent blades 5 on a plane perpendicular to the center line of the wheel body 1 overlap. A groove is arranged on one side of the blade 5, and a buffer 3 is arranged in the groove. The buffer 3 is made of a flexible material and is used to contact the glass in the working state. During the transmission process, the side of the wheel body 1 where the buffer 3 is arranged can alternately contact the lower surface of the glass, so that the cooling wind can blow through the lower surface of the glass, avoiding continuous contact between the transmission wheel and the lower surface of the glass, thereby achieving the purpose of weakening the stress spot of the tempered glass.

[0034] In this example, the blades 5 are arranged at an angle, which means that there is an angle between the bottom edge where the blades 5 are connected to the wheel body 1 and the center line of the wheel body 1, that is, the bottom edge is not parallel to the center line of the wheel body 1. This arrangement allows the projections of two adjacent blades 5 on a plane perpendicular to the center line of the wheel body 1 to overlap. Figure 2 In the embodiment, A contacts the glass first, and then B contacts the glass. At this time, C also contacts the glass, so that the blade 5 can better support the glass and ensure stable transmission.

[0035] In some embodiments, the blade 5 is spiral-shaped, that is, the blade 5 is twisted.

[0036] See also Figure 3The blade 5 includes a first side surface, a second side surface 51, a third side surface 52, a fourth side surface 53, a fifth side surface, and a sixth side surface. The first side surface is connected to the wheel body 1 (i.e., coplanar). The second side surface 51 is flush with one end surface of the wheel body 1. The third side surface 52 is connected to the second side surface 51, the fourth side surface 53, and the fifth side surface. The fourth side surface 53 and the fifth side surface (located on the back side of the fourth side surface 53) are respectively located on both sides of the third side surface 52. The sixth side surface is opposite to the second side surface 51. The sixth side surface is flush with the other end surface of the wheel body 1. The sixth side surface is connected to the third side surface 52, the fourth side surface 53, and the fifth side surface.

[0037] In some embodiments, the blade 5 and the wheel body 1 are integrally formed; the blade 5 and the wheel body 1 are made of metal; and the thickness of the blade 5 is 5-12 mm.

[0038] In some embodiments, the buffer member 3 is an aramid rope.

[0039] In some embodiments, the transmission wheel further comprises a fastener 2, and two mounting grooves 4 are formed on the blade 5, the two mounting grooves 4 are respectively located at opposite ends of the groove, the mounting grooves 4 are connected to the groove, the two ends of the buffer 3 are respectively located in the two mounting grooves, and the fastener 2 is used to fix the buffer 3 located in the mounting grooves. Figure 3 The groove is located on the third side 52 of the blade 5, and the two mounting grooves can be located on the second side 51 and the sixth side respectively, that is, in the working state, the fastener 2 will not contact the glass.

[0040] In some embodiments, the fastener 2 is a screw, the inner wall of the mounting groove 4 is provided with an internal thread, the two ends of the buffer 3 are respectively located in the two mounting grooves, and the buffer 3 is fixed by installing the fastener 2 in the mounting groove 4. In other embodiments, the buffer 3 can be bonded in the groove, and the buffer 3 will not be separated from the mounting groove 4 during the transmission process.

[0041] Example 2

[0042] This example provides a transmission device, see Figure 6 The device includes a transmission shaft 7 and a glass tempering transmission wheel, and the glass tempering transmission wheel is sleeved on the transmission shaft 7.

[0043] In some embodiments, a plurality of glass-tempered transmission wheels are provided, and the plurality of glass-tempered transmission wheels are distributed along the axial direction of the transmission shaft 7 , so that the transmission is more stable. The transmission device further includes a fixed bearing 6 , and the fixed bearing 6 is sleeved outside the transmission shaft 7 .

[0044] The glass in this example is curved glass 8. The flat glass is formed into curved glass 8 after being curved. The curved glass 8 is then contact-transmitted through a transmission device. During transmission, the glass discontinuously contacts the transmission wheel. The blades 5 on the wheel body 1 of the transmission wheel contact the lower surface of the glass alternately, so that cooling wind can blow toward the glass surface through the gap between two adjacent blades 5, thereby achieving uniform cooling and weakening of stress spots.
