Description

Technical Field

[0001] This utility model relates to the field of glass tempering production technology, and in particular to a glass tempering furnace production line. Background Technology

[0002] Tempered glass is a type of safety glass. It is actually a prestressed glass. To improve its strength, chemical or physical methods are typically used to create compressive stress on the glass surface. When the glass is subjected to external force, this surface stress is first neutralized, thus increasing its load-bearing capacity and enhancing its resistance to wind pressure, temperature changes, and impact. The commonly used physical tempering method involves heating the glass in a tempering furnace to its softening point. At this point, the glass retains its original shape, but the particles within it have a certain ability to migrate, allowing for structural adjustment to quickly eliminate internal stress. The tempered glass is then rapidly cooled by blowing air. Once the temperature reaches equilibrium, compressive stress is generated on the glass surface, and tensile stress is generated in the inner layer. This creates a uniform and regularly distributed internal stress, increasing the tensile strength of the glass as a brittle material, thereby improving its bending and impact resistance.

[0003] A search revealed a Chinese patent for a glass tempering furnace production line, publication number CN206607164U, which includes a tempering furnace, a bellows, and conveyor rollers. The tempering furnace is equipped with carbon fiber heating tubes, and the bellows has upper and lower ventilation fans on its left side. This invention uses carbon fiber heating tubes instead of furnace wires for heating, offering advantages such as rapid heating and uniform heating of the glass plate. The ventilation fans inside the bellows promptly expel water vapor generated during the glass cooling process, ensuring the quality of the tempered glass.

[0004] The aforementioned patent uses carbon fiber heating tubes to replace furnace wire heating, which improves the heating effect to a certain extent. However, this technology still has obvious drawbacks: First, it does not recover and utilize the heat generated by the tempering furnace, resulting in energy waste and increased production costs. Second, during the material transfer process, there is a lack of a correction mechanism for the material transfer position, which can easily lead to material deviation, affecting the subsequent processing accuracy and product qualification rate. Therefore, we propose a glass tempering furnace production line. Utility Model Content

[0005] The purpose of this invention is to provide a glass tempering furnace production line to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0026] Example

[0027] like Figure 1-4 As shown, this utility model provides a technical solution: a glass tempering furnace production line, including an equipment base 1, a workbench 2 for carrying processed materials on the top of the equipment base 1, a transmission channel 201 on the top of the workbench 2, multiple transmission rollers 3 in the transmission channel 201, the multiple transmission rollers 3 cooperating to rotate to realize the conveying of materials in the transmission channel 201, a tempering furnace body 4 on the top of the workbench 2 and above the transmission channel 201, a cooling box 5 for cooling the tempered materials on one side of the tempering furnace body 4, a preheating box 6 for preheating the materials on the other side of the tempering furnace body 4, heat preservation cavities 7 are opened inside the shells of both the tempering furnace body 4 and the preheating box 6, and a correction component 8 for correcting the material conveying position is provided on one side of the preheating box 6 and on the front and back of the top of the workbench 2.

[0028] Mounting bases 401 are fixedly attached to the top front and back of the tempering furnace body 4. Multiple heating rods 402 are arranged between the two mounting bases 401. The mounting bases 401 are used to fix the heating rods 402, ensuring that the installation position of the heating rods 402 in the tempering furnace body 4 is stable, so that the heating rods 402 can be evenly distributed and provide a uniform heating environment for the material. The heating rods 402, as heating elements of the tempering furnace body 4, generate heat after being energized, and heat the material in the transmission channel 201 to make it reach the temperature required for tempering. The multiple heating rods 402 work together to improve heating efficiency and heating uniformity, ensure good tempering effect of the material, and improve product quality.

[0029] Multiple air coolers 501 are installed on the top of the cooling box 5 near the front and back. The air coolers 501 blow cold air into the cooling box 5 to accelerate the airflow inside the cooling box 5, remove the heat from the surface and inside of the tempered material, and achieve rapid cooling of the material. The multiple air coolers 501 work together to enhance the cooling effect, shorten the cooling time, improve production efficiency, and at the same time ensure uniform cooling of the material to avoid product quality problems caused by uneven cooling.

[0030] The preheating chamber 6 is equipped with a fixed base 601, and the bottom of the fixed base 601 has multiple air outlets 6011. The fixed base 601 supports and fixes the air outlets 6011, so that the air outlets 6011 maintain a stable position and layout within the preheating chamber 6, ensuring that hot air can be evenly discharged from the air outlets 6011 to preheat the material uniformly. The air outlets 6011 are the channels through which the preheating chamber 6 delivers hot air to the material. After the hot air is discharged from the air outlets 6011, it comes into full contact with the material during the transmission process, thereby preheating the material. The setting of multiple air outlets 6011 can increase the contact area between the hot air and the material, improve the preheating efficiency and uniformity, and prepare for the subsequent tempering process.

[0031] A blower 602 is installed on the top of the tempering furnace body 4. The blower 602 is connected to the fixed base 601 by a pipe. The blower 602 draws out the hot air inside the tempering furnace body 4, recovering the heat that might otherwise be lost. The heat is then transported to the fixed base 601 of the preheating box 6 through the pipe. This not only realizes the recycling of heat and reduces overall energy consumption, but also reduces dependence on external energy, improves energy utilization efficiency, and reduces production costs. The pipe serves as a channel for heat transmission, stably transporting the hot air drawn by the blower 602 to the fixed base 601 of the preheating box 6, ensuring the sealing and stability of heat transmission, preventing heat loss during transmission, and ensuring the preheating effect.

[0032] The insulation cavity 7 is filled with ceramic fiber material to reduce heat loss from the tempering furnace body 4 and the preheating box 6. The ceramic fiber material has good thermal insulation properties. When filled into the insulation cavity 7, it can effectively prevent the heat inside the tempering furnace body 4 and the preheating box 6 from being transferred to the external environment. Compared with other ordinary materials, the ceramic fiber material can significantly reduce the heat loss rate, reduce energy waste, maintain the stability of the internal temperature of the equipment, ensure the accuracy and consistency of the processing technology, and extend the service life of the equipment.

[0033] The alignment component 8 includes a fixed plate 801 fixed to the top of the workbench 2. Alignment plates 802 are provided on the inner sides of both fixed plates 801. Hydraulic cylinders 803 are provided on the outer surfaces of both fixed plates 801. The output end of the hydraulic cylinder 803 is fixedly connected to the outer surface of the alignment plate 802, driving the alignment plate 802 to move and adjust the material conveying position. Auxiliary guide rods 804 are slidably connected to both sides of the fixed plates 801. The other end of the auxiliary guide rods 804 is fixedly connected to the alignment plate 802, used to move the alignment plate 802. Guiding and stabilizing support; the fixing plate 801 is fixed to the top of the workbench 2, providing an installation base for the straightening plate 802, hydraulic cylinder 803 and auxiliary guide rod 804, ensuring the stability of the overall structure of the straightening assembly 8, so that it can reliably correct the material transmission position. The straightening plate 802 is in direct contact with the material, and through the drive of the hydraulic cylinder 803, it adjusts the position of the material that has deviated during the transmission process, so that it returns to the correct transmission path, ensuring that the material can accurately enter the subsequent processing equipment, improving processing accuracy and product qualification rate.

[0034] The working process of this utility model is as follows: When using a glass tempering furnace production line, the material to be processed is first placed on the transmission channel 201 of the workbench 2. Multiple transmission rollers 3 within the transmission channel 201 rotate in coordination, forming a stable transmission force, allowing the material to be smoothly conveyed along the transmission channel 201. The arrangement of the transmission rollers 3 ensures that the material maintains a continuous and stable movement during the transmission process, preparing it for subsequent processing stages.

[0035] When materials are conveyed on the conveying channel 201, the alignment components 8 located on the top of the workbench 2 near the front and back begin to work. The fixed plate 801, as the basic structure of the alignment components 8, is firmly installed on the top of the workbench 2 to provide support for other components. The hydraulic cylinder 803 drives the alignment plate 802 to move, and the auxiliary guide rod 804 guides and stabilizes the movement of the alignment plate 802. When the material conveying position deviates, the hydraulic cylinder 803 is activated, pushing the alignment plate 802 to move, contact the material, and adjust its position so that the material returns to the correct conveying path, ensuring that the material can accurately enter the subsequent processing equipment, improving processing accuracy and product qualification rate.

[0036] After being aligned, the material enters the preheating box 6. The fixing seat 601 inside the preheating box 6 supports and fixes multiple air outlets 6011, ensuring that hot air can be discharged evenly from the air outlets 6011. When the material passes through the preheating box 6 during the transmission process, the hot air is discharged from the air outlets 6011 and comes into full contact with the material, achieving uniform preheating of the material. The multiple air outlets 6011 increase the contact area between the hot air and the material, improving the preheating efficiency and uniformity, preparing for the subsequent tempering process, so that the material reaches a suitable initial temperature before entering the tempering furnace body 4, reducing energy consumption and time in the tempering process.

[0037] The exhaust fan 602 at the top of the tempering furnace body 4 extracts the hot air from the furnace. This hot air is stably transported to the fixed seat 601 of the preheating box 6 through pipelines. The pipelines ensure the sealing and stability of the hot air transmission, preventing the hot air from being lost during the transmission process. In this way, the heat that might otherwise be lost is recovered and reused, which not only reduces the overall energy consumption and the dependence on external energy, but also improves energy utilization efficiency and reduces production costs.

[0038] The preheated material continues to be conveyed to the tempering furnace body 4 via the transfer roller 3. Multiple heating rods 402 are fixed in the mounting seats 401 on the top front and back of the tempering furnace body 4, so that the heating rods 402 are evenly distributed. The heating rods 402 generate heat after being energized, providing a uniform heating environment for the material. The multiple heating rods 402 work together to improve heating efficiency and heating uniformity, so that the material reaches the temperature required for tempering, ensuring good tempering effect and improving product quality.

[0039] After being tempered, the material enters the cooling box 5 from the tempering furnace body 4. Multiple air coolers 501 on the top, front and back of the cooling box 5 work together to blow cold air into the cooling box 5, accelerating the airflow inside the box and removing the heat from the surface and interior of the tempered material, thus achieving rapid cooling of the material. The combined effect of multiple air coolers 501 enhances the cooling effect, shortens the cooling time, improves production efficiency, and ensures uniform cooling of the material, avoiding product quality problems caused by uneven cooling.

[0040] After cooling, the material continues to be conveyed through the transfer roller 3 and is finally output from the production line as a qualified tempered glass product. Throughout the process, the various structures cooperate with each other to efficiently and stably complete the tempering process of the material, ensuring product quality and production efficiency.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
