Description

Technical Field

[0001] The utility model belongs to the technical field of glass annealing, and particularly relates to an annealing device for glass production. Background Art

[0002] Glass is an inorganic non-metallic material that is currently widely used and has a wide range of applications. It can be used in construction, daily use, art, instrumentation and other fields. There are many types of glass. Annealing equipment is required in the production process of glass. The annealing equipment is used to heat treat the glass to reduce the residual stress of the glass, stabilize the size, and reduce the tendency to deformation and cracking.

[0003] After searching, the patent with application number 201721523272.5 discloses an annealing device for glass production. The patent can complete the annealing process at one time by setting a heating zone 6, a heat preservation zone 9, a cooling zone 11 and a cooling zone 14, without the need for secondary annealing, thereby greatly reducing the glass production cycle. However, it adopts a transmission roller conveying method. When the glass moves on the transmission roller, the fan can only dissipate heat on the upper surface of the glass, resulting in low heat dissipation efficiency. The transmission roller conveying method may cause scratches on the glass surface, thereby affecting the processing quality. Utility Model Content

[0015] See attached Figure 1-3As shown, an annealing device for glass production includes a glass conveying mechanism 7 and a cooling mechanism 8 located in an annealing channel 1. A support leg 2 is provided on the bottom side of the annealing channel 1. Four partitions are provided in the annealing channel 1, which are a heating zone 3, a heat preservation zone 4, a cooling zone 5 and a cooling zone 6 from left to right. Heating plates 9 are provided on the upper and lower sides of the heating zone 3, and heat insulation layers 10 are provided on the upper and lower sides of the heat preservation zone 4. Glass conveying mechanisms 7 are provided in the four partitions, and a cooling mechanism 8 is provided in the cooling zone 5; the glass conveying mechanism 7 includes a rotating shaft 71, a reduction motor 72, a conveying wheel 73 and a conveying trough 74. The front and rear ends of the upper side of the inner cavity of the annealing channel 1 are equidistantly connected to a plurality of rotating shafts 71. A reduction motor 72 connected to the rotating shaft 71 is installed on the upper side of the annealing channel 1. Conveying wheels 73 are fixed to the bottom ends of the rotating shafts 71, and conveying troughs 74 are provided on the outer sides of the conveying wheels 73. The cooling mechanism 8 includes a hydraulic cylinder 81, a bellows 82, blower 83 and air inlet pipe 84, hydraulic cylinders 81 are installed on the upper and lower sides of the inner cavity of the cooling zone 5, and bellows 82 are fixed to the telescopic ends of the hydraulic cylinder 81. Blowers 83 are installed at the air inlets on the outside of the bellows 82, and air inlet pipes 84 are installed at the air inlets of the blower 83. Through grooves are provided on the upper and lower sides of the cooling zone 5, and the air inlet pipe 84 is slidably connected in the through grooves. A number of air outlet holes 13 are equidistantly provided on the inner side of the bellows 82, and a number of exhaust holes 11 are equidistantly provided on the front and rear sides of the cooling zone 5. By setting up a glass conveying mechanism 7 and adopting a suspended glass conveying mechanism 7, scratches on the glass surface caused by the transmission roller are avoided, and the processing quality is guaranteed. In conjunction with the cooling mechanisms 8 at the upper and lower ends, the glass surface can be cooled at the same time, thereby improving the cooling efficiency. The bellows 82 is controlled by the hydraulic cylinder 81, which is convenient for adjusting the cooling position of the glass and improving the cooling effect.

[0016] The inner sides of the bellows 82 are rotatably connected with rollers 12 via rotating shafts. The rotation directions of the rollers 12 and the conveying wheel 73 are consistent. By arranging the rollers 12 around the inner sides of the bellows 82, the air outlets 13 on the inner side of the bellows 82 can maintain a certain distance from the glass surface when the glass is conveyed, thereby further improving the cooling effect.

[0017] Working principle: The glass to be annealed enters the annealing channel 1, and the reduction motor 72 drives the conveying wheel 73 to rotate through the rotating shaft 71, and the glass is conveyed through the conveying grooves 74 of the conveying wheels 73 at the front and rear ends. The glass first enters the heating zone 3 and is heated by the heating plate 9, then enters the insulation zone 4 for insulation treatment, and then enters the cooling zone 5. At this time, the hydraulic cylinder 81 extends, thereby driving the bellows 82 to approach each other until the roller 12 inside the bellows 82 contacts the surface of the conveyed glass, and the blower 83 conveys external air to the bellows 82 through the air inlet pipe 84, and discharges it through the air outlet 13 inside the bellows 82, thereby achieving the cooling treatment of the glass. The cooled glass continues to cool down. The glass is then conveyed to the cooling zone for natural cooling. A suspended glass conveying mechanism 7 is used to avoid scratches on the glass surface by the transmission roller, thereby ensuring the processing quality. In conjunction with the cooling mechanisms 8 at the upper and lower ends, the glass surface can be cooled at the same time, thereby improving the cooling efficiency. The bellows 82 is controlled by a hydraulic cylinder 81, which makes it easy to adjust the cooling position of the glass and improves the cooling effect. Rollers 12 are provided around the inner side of the bellows 82, so that the air outlet 13 on the inner side of the bellows 82 can maintain a certain distance from the glass surface when the glass is conveyed, thereby further improving the cooling effect. The several air outlets 13 on the inner side of the bellows 82 ensure the uniformity of the glass cooling.
