Description

Technical Field

[0001] This utility model relates to the field of glass heating technology, and in particular to a glass convection heating device. Background Technology

[0002] In the glass manufacturing industry, especially in the production of automotive window glass, the heating process is crucial, directly affecting the final quality and performance of the glass. Currently, glass heating mainly utilizes resistance heating.

[0003] Resistance heating devices typically involve arranging resistance wires inside or around glass production equipment. During operation, an electric current passes through the resistance wires, generating heat, which is then conducted to heat the glass. However, this heating method has the following drawbacks: 1. It is difficult to achieve a perfectly uniform arrangement of the resistance wires, resulting in varying distances between different parts of the glass and the wires, leading to uneven heat transfer. 2. The heat transfer efficiency of conduction is relatively low, creating a large temperature gradient within the glass. This not only affects heating efficiency but also easily leads to uneven heating, ultimately causing glass deformation due to stress differences and affecting the optical quality of the glass.

Please see below. Figures 1 to 7 The diagram illustrates a preferred embodiment of a glass convection heating device, comprising a housing 1, a first high-temperature fan 2, a second high-temperature fan 3, convection ducts 4, heating pipes 5, and a fixing block 6. Several first high-temperature fans 2 are arranged on one side of the housing 1, and several second high-temperature fans 3 are arranged on the other side. Two rows of convection ducts 4 are arranged inside the housing 1. One end of each convection duct 4 is connected to one side of the housing 1 via the fixing block 6, and the other end of each convection duct 4 extends through the other side of the housing 1. Several heating pipes 5 are arranged between the two rows of convection ducts 4, each heating pipe 5 containing a heating wire. An air outlet is provided on the outer wall of each convection duct 4 on the side pointing towards the heating pipe 5. In this embodiment, see [reference needed]. Figure 1 and Figure 2 As shown, there are four first high-temperature fans 2, arranged in two groups, and two second high-temperature fans 3, arranged in one group, with the two second high-temperature fans 3 located between the two first high-temperature fans 2. In operation, the first high-temperature fans 2 and the second high-temperature fans 3 start simultaneously, drawing air into the housing 1. The air flows within the housing 1, and as it passes the heating tube 5, the heat generated by the heating wire is transferred to the air, causing it to heat up and form a hot airflow. The hot airflow is blown out through the air outlet on the convection duct 4, pointing towards the heating tube 5, directly acting on the glass surface and creating convection to heat the glass. This heating method evenly transfers heat to all parts of the glass through the flow of hot air. The convection of hot air on the glass surface allows for rapid and uniform coverage of the glass, reducing temperature differences between different parts and effectively solving the problem of uneven heating in existing heating devices. Furthermore, uniform heating makes the internal stress distribution of the glass more uniform, greatly reducing the possibility of deformation due to uneven heating, laying a solid foundation for improving the optical quality of the vehicle window glass surface.

[0023] Furthermore, as a preferred embodiment, several first high-temperature fans 2 and several second high-temperature fans 3 are distributed on both sides of the two rows of convection ducts 4. In this embodiment, see... Figure 2As shown, two second high-temperature fans 3 are distributed on the upper and lower sides of the convection duct 4, while four first high-temperature fans 2 are also distributed on the upper and lower sides of the convection duct 4, with the first high-temperature fans 2 and the second high-temperature fans 3 staggered. This allows air to enter the housing 1 evenly from different positions, forming a more complex and uniform airflow path within the housing 1. The staggered distribution of the high-temperature fans on both sides promotes thorough mixing of air within the housing 1, avoiding localized dead zones in airflow and ensuring that hot air can contact the glass surface more comprehensively and evenly, further reducing temperature differences on the glass surface and improving heating uniformity. Moreover, this uniform heating helps the glass maintain good flatness during the heating process, thereby improving the optical quality of the car window glass surface, making light transmission through the glass more regular, reducing refraction and scattering phenomena, and improving visual clarity.

[0024] Furthermore, as a preferred embodiment, it also includes caster legs 7, a wheel bracket 8, and wheels 9. Caster legs 7 are located at the upper end of the housing 1, and a wheel bracket 8 is located on one side of the caster legs 7. Wheels 9 are mounted on the wheel bracket 8. The caster legs 7 are bolted to the upper end of the housing 1, and the wheel bracket 8 is bolted to the caster legs 7. The wheels 9 are mounted on the wheel bracket 8. This allows the entire heating device to have flexible movement, facilitating position adjustments within the glass production workshop according to the production process and layout. In this embodiment, the wheels 9 can cooperate with a track on the top of the external wall, thus restricting the movement path of the housing 1. Under the action of an external drive mechanism, the housing 1 can be driven to move along the track.

[0025] Furthermore, as a preferred embodiment, it also includes roller conveyor beams 10, with two roller conveyor beams 10 arranged on both sides of the housing 1. It also includes sprocket shafts 11, bearing seats 12, and double-row sprockets 13. Several sprocket shafts 11 are arranged on the roller conveyor beams 10, and the sprocket shafts 11 are connected to the roller conveyor beams 10 via bearing seats 12. Double-row sprockets 13 are arranged on the sprocket shafts 11. In this embodiment, one end of the sprocket shaft 11 passes through the bearing seat 12 and the side wall of the housing 1 and is connected to the heating tube 5, thus driving the heating tube 5 to rotate during the heating process.

[0026] Furthermore, as a preferred embodiment, the inner wall of the housing 1 has an insulation board 14, and the fixing block 6 is connected to the corresponding insulation board 14. In this embodiment, the insulation board 14 is fixedly connected to the inner wall of the housing 1, and the convection ducts 4 can all penetrate the insulation board 14 and the side wall of the housing 1 and extend out of the housing 1 to connect with an external heat source for pumping air into the housing 1. The insulation board 14 can effectively reduce heat loss and improve energy utilization efficiency.

[0027] Furthermore, as a preferred embodiment, it also includes support beams 15. Support beams 15 are provided on both outer walls of the housing 1. The first high-temperature fan 2 and the second high-temperature fan 3 are both mounted on the support beams 15, and both the first high-temperature fan 2 and the second high-temperature fan 3 extend into the housing 1. The support beams 15 provide a stable mounting foundation for the fans, ensuring the stability of the fans during operation. The support beams 15 are bolted to the side walls of the housing 1, and both the first high-temperature fan 2 and the second high-temperature fan 3 can be bolted to the support beams 15. Both the first high-temperature fan 2 and the second high-temperature fan 3 penetrate the insulation board 14 and are used to pump hot air into the housing 1.

[0028] In this embodiment, a PLC controller is also included, which is used to connect with the first high-temperature fan 2, the second high-temperature fan 3, as well as the external heat source and the heating wire inside the heating tube 5, to control the coordinated operation of each device.

[0029] In this embodiment, a temperature sensor can be installed on one of the insulation boards 14 to detect the temperature inside the box 1, and the temperature sensor is connected to the PLC controller, which facilitates the control of the temperature range inside the box 1.

[0030] In this embodiment, baffles 16 are provided at both ends of the box 1, and openings 17 for glass to pass through are provided on the baffles 16. The glass can enter and leave the box 1 under the action of an external conveying mechanism.

[0031] In this embodiment, the double-row sprocket 13 can be connected to an external chain, the chain can be connected to the output end of an external motor, the motor can be connected to a PLC controller, and the motor drives the chain to rotate the double-row sprocket 13, thereby driving the heating tube 5 to rotate.

[0032] In use, first, the heating element 5 is turned on to heat the inside of the chamber 1. Then, the first high-temperature fan 2, the second high-temperature fan 3, and the external heat source are turned on to blow hot air into the chamber 1 until the internal temperature of the chamber 1 reaches the specified range. Then, the glass enters the chamber 1 through the opening 17 on the baffle 16 at one end of the chamber 1. The hot air blown out by the first high-temperature fan 2, the second high-temperature fan 3, and the convection duct 4 will form convection and act on the glass surface to achieve uniform heating of the glass. After heating is completed, the glass leaves the chamber 1 through the opening 17 on the baffle 16 at the other end of the chamber 1 and can proceed to the next process.
