Description

Technical Field

[0001] This utility model relates to the field of tempered glass production technology for household appliances, specifically to a tempering furnace for household appliance glass production with high cooling efficiency. Background Technology

[0002] Tempered glass is widely used in the home appliance industry due to its surface compressive stress strengthening properties. Traditional tempering furnaces heat the glass in a heating chamber and then cool it in a cooling chamber, which causes compressive stress to form on the surface of the cooled glass and tensile stress to form inside the glass, thereby improving the strength of the glass.

[0003] However, the U-shaped and S-shaped glass widely used in the home appliance industry has a curved structure. When the existing tempering furnace cools the irregularly shaped glass, the cold air blows towards the glass surface at a fixed angle, which creates a cooling blind zone. This results in uneven cooling in different parts of the irregularly shaped glass, thus affecting the quality of tempered glass products. Therefore, there are still shortcomings and deficiencies in the existing technology. Utility Model Content

[0004] This invention provides a tempering furnace for the production of household appliance glass with high cooling efficiency, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a tempering furnace for household appliance glass production with high cooling efficiency, including a heating box, a cooling box provided on the outlet side of the heating box, and a conveying mechanism passing through the heating box and the cooling box; multiple air supply branch pipes parallel to the conveying direction of the conveying mechanism are rotatably connected inside the cooling box, and nozzles facing the conveying mechanism are installed on the air supply branch pipes. The air supply branch pipes are connected to the main air supply pipe through a rotary joint. The end of the main air supply pipe away from the air supply branch pipes extends to the outside of the cooling box and is connected to a cold air fan; a lead screw perpendicular to the air supply branch pipes is rotatably connected inside the cooling box. One end of the lead screw extends to the outside of the cooling box and is driven by a driving mechanism. A slider corresponding to the air supply branch pipe is threaded on the lead screw. The slider is slidably connected to the inner wall of the cooling box. A telescopic rod is provided between the slider and the corresponding air supply branch pipe. One end of the telescopic rod is hinged to the slider, and the other end of the telescopic rod is fixedly connected to the air supply branch pipe.

[0006] Preferably, a groove parallel to the lead screw is provided on the inner wall of the cooling box, and the slider is located in the groove and slidably connected to the groove.

[0007] Preferably, the air supply branch pipe includes a first air supply branch pipe and a second air supply branch pipe, with the first air supply branch pipe located above the conveying mechanism and the second air supply branch pipe located below the conveying mechanism.

[0008] Preferably, there are two lead screws, one of which corresponds to the first air supply branch pipe and the other corresponds to the second air supply branch pipe.

[0009] Preferably, the drive mechanism includes a stepper motor, the output shaft of which is driven to one of the lead screws, and the two lead screws are driven to each other through a transmission assembly.

[0010] The beneficial effects of this utility model are as follows: (1) This utility model drives the screw to rotate back and forth through the drive mechanism. The screw can drive the slider to move back and forth, so that the telescopic rod can rotate back and forth around the air supply branch pipe. The telescopic rod can drive the air supply branch pipe to rotate back and forth, so that the air supply branch pipe can drive the nozzle to swing back and forth, so that the cold air sprayed out can swing and sweep. In this way, the swinging cold air can better cover the complex curved surface of the irregular glass, thereby improving the uniformity of cooling of the irregular glass; (2) By setting the first air supply branch pipe and the second air supply branch pipe above and below the conveying mechanism respectively, the cold air can be blown from the upper and lower surfaces of the irregular glass at the same time, realizing double-sided synchronous cooling, thereby increasing the heat exchange area, shortening the cooling time, and improving the overall production efficiency.

Detailed Implementation

[0015] The present invention will now be further described with reference to the accompanying drawings.

[0016] like Figure 1-3As shown, this utility model provides a high-efficiency tempering furnace for the production of household appliance glass, including a heating box 1, a cooling box 2 located at the outlet side of the heating box 1, and a conveying mechanism 3 passing through the interior of the heating box 1 and the cooling box 2; multiple air supply branch pipes 4 rotatably connected inside the cooling box 2, parallel to the conveying direction of the conveying mechanism 3, with nozzles 5 installed on the air supply branch pipes 4 facing the conveying mechanism 3, and the air supply branch pipes 4 connected to a main air supply pipe 7 via a rotary joint 6, with one end of the main air supply pipe 7 extending away from the air supply branch pipes 4 to... A cooling fan 8 is connected to the outside of the cooling box 2; a lead screw 9 perpendicular to the air supply branch pipe 4 is rotatably connected inside the cooling box 2. One end of the lead screw 9 extends to the outside of the cooling box 2 and is connected to a drive mechanism 10. A slider 11 corresponding to the air supply branch pipe 4 is threaded onto the lead screw 9. The slider 11 is slidably connected to the inner wall of the cooling box 2. A telescopic rod 12 is provided between the slider 11 and the corresponding air supply branch pipe 4. One end of the telescopic rod 12 is hinged to the slider 11, and the other end of the telescopic rod 12 is fixedly connected to the air supply branch pipe 4.

[0017] Specifically, in use, the irregularly shaped glass is placed on the conveying mechanism 3, which drives the glass into the heating chamber 1 at a constant speed for heating. Then, the conveying mechanism 3 drives the glass into the cooling chamber 2. The cold air blower 8 continuously outputs cold air, which passes through the main air supply pipe 7, the rotary joint 6, and the branch air supply pipe 4 before being sprayed out from the nozzle 5. This allows the cold air to blow onto the surface of the irregularly shaped glass, cooling it down. At the same time, the drive mechanism 10 drives the lead screw 9 to rotate back and forth, and the lead screw 9 drives the slider 11 to move back and forth, causing the branch air supply pipe 4 at the position of the telescopic rod 12 to rotate back and forth. Since the telescopic rod 12 and the branch air supply pipe 4 are fixedly connected, while the branch air supply pipe 4 and the main air supply pipe 7 are rotatably connected through the rotary joint 6, the telescopic rod 12 can drive the branch air supply pipe 4 to rotate back and forth, causing the nozzle 5 to swing back and forth. This allows the sprayed cold air to swing and sweep, thus better covering the complex curved surface of the irregularly shaped glass and improving the uniformity of cooling.

[0018] In some embodiments, a groove 13 parallel to the lead screw 9 is provided on the inner side wall of the cooling box 2, and the slider 11 is located in the groove 13 and slidably connected to the groove 13, so that the slider 11 moves along the lead screw 9 through the groove 13.

[0019] In some embodiments, the air supply branch pipe 4 includes a first air supply branch pipe 41 and a second air supply branch pipe 42. The first air supply branch pipe 41 is located above the conveying mechanism 3, and the second air supply branch pipe 42 is located below the conveying mechanism 3. In this way, cold air can be blown from the upper and lower surfaces of the irregularly shaped glass at the same time, realizing double-sided synchronous cooling, thereby increasing the heat exchange area, shortening the cooling time, and improving the overall production efficiency.

[0020] In some embodiments, there are two lead screws 9, one of which corresponds to the first air supply branch pipe 41 and the other corresponds to the second air supply branch pipe 42. The two lead screws 9 drive the first air supply branch pipe 41 and the second air supply branch pipe 42 to rotate, causing the nozzles 5 above and below the irregularly shaped glass to swing, thereby uniformly cooling the upper and lower sides of the irregularly shaped glass.

[0021] In some embodiments, the drive mechanism 10 includes a stepper motor 101, the output shaft of which is connected to one of the lead screws 9. The two lead screws 9 are connected by a transmission assembly 102, which may be a sprocket transmission mechanism or a gear transmission mechanism, etc. Specifically, in use, the stepper motor 101 drives one of the lead screws to rotate, and the lead screw 9 drives the other lead screw 9 to rotate through the transmission assembly 102, so that the two lead screws 9 can rotate simultaneously. This ensures that the nozzles 5 on the upper and lower surfaces of the irregularly shaped glass can reciprocate synchronously, thereby ensuring the uniformity of cooling of the irregularly shaped glass in the thickness direction.

[0022] The above embodiments can be combined with each other.

[0023] The above embodiments are not intended to limit the shape, material, structure, etc. of this utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
