Description

Technical Field

[0001] The invention relates to the technical field of glass processing equipment, and in particular to a glass tempering furnace. Background Art

[0002] Glass tempering furnace mainly uses physical or chemical methods to form a compressive stress layer on the surface of the glass and a tensile stress layer inside the glass, thereby achieving the purpose of improving the strength of the glass. The glass is heated to the softening temperature point through the glass tempering furnace, so that the particles in the glass have a certain migration ability and adjust the structure, and then the glass is blown and quenched, so that the glass produces a uniform and regularly distributed internal stress, thereby improving the strength of the glass.

[0003] The basic production process of glass tempering is: placing, heating, cooling, and taking out the glass. In the cooling stage, the glass is cooled by spraying cold air evenly from the upper and lower cooling air grids onto the upper and lower surfaces of the heated glass. However, during the rapid cooling process of the high-temperature glass, it may explode due to various reasons, and the broken glass will fall to the ground from between the conveyor rollers. In the prior art, the broken glass on the ground is usually cleaned manually, which increases the labor intensity of the workers, and the cleaning process requires downtime, affecting production efficiency. In addition, some of the broken glass powder will adhere to the surface of the conveyor roller, which is easy to affect the appearance and quality of the glass produced later. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the prior art and provide a glass tempering furnace that can automatically clean and collect broken glass without manual cleaning, thereby reducing labor intensity and improving work efficiency.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: a glass tempering furnace, comprising a feeding track, a heating chamber and a cooling chamber are sequentially arranged on the feeding track along the conveying direction of the feeding track, a plurality of feeding conveying rollers are arranged on the feeding track near the feeding end of the heating chamber, a plurality of discharging conveying rollers are arranged on the feeding track near the discharging end of the cooling chamber, a conveyor belt is arranged below the discharging conveying roller, the conveyor belt is arranged along the conveying direction of the feeding track, a collecting box is arranged at the discharging end of the conveyor belt, a cleaning mechanism 1 is arranged at the bottom of the discharging conveying roller, the cleaning mechanism 1 is located above the conveyor belt, the cleaning mechanism 1 is used to clean the discharging conveying roller so that the glass cullet particles adhered to the discharging conveying roller fall onto the conveyor belt, a cleaning mechanism 2 is arranged at the discharging end of the conveyor belt, the cleaning mechanism 2 is used to clean the conveyor belt so that the glass cullet particles adhered to the conveyor belt fall into the collecting box.

[0006] By adopting the above technical scheme, the glass is placed on the feed conveyor roller during feeding, and under the conveying action of the feed conveyor roller, the glass is transported to the heating chamber and the cooling chamber for tempering. When the glass is broken after rapid cooling, the broken glass fragments fall onto the conveyor belt from the gaps between the discharge conveyor rollers, and the broken glass is transported to the collection box for collection through the conveyor belt. No manual cleaning is required, which saves time and effort. Since fine glass fragments will be formed and adhere to the discharge conveyor roller after the tempered glass explodes, the glass fragments adhered to the discharge conveyor roller can be cleaned by the cleaning mechanism that reciprocates along the feeding track and under the rotation of the discharge conveyor roller, thereby avoiding the subsequent occurrence of pitting on the glass surface. Under the cleaning action of the cleaning mechanism one, the broken glass particles are scraped onto the conveyor belt and transported to the collection box through the conveyor belt for collection. However, the fine broken glass particles are also easy to adhere to the conveyor belt and are not easy to fall into the collection box. As the conveyor belt moves, the broken glass particles may reach the bottom of the conveyor belt and fall on the ground, requiring manual cleaning. Not only is cleaning inconvenient, but there are also certain safety hazards. By arranging a cleaning mechanism two at the discharge end of the conveyor belt, the broken glass particles adhering to the conveyor belt can be cleaned, ensuring that the broken glass blocks and broken glass particles can be cleaned into the collection box for unified collection. The cleaning is cleaner and more thorough, which greatly reduces the labor intensity of workers. There is no need to stop the machine during the cleaning process, thereby improving work efficiency.

[0008] By adopting the above technical solution, when the discharge conveyor roller needs to be cleaned, the cleaning rod is driven by the driving mechanism to reciprocate along the feeding track. As the discharge conveyor roller rotates, the cleaning rod cleans the discharge conveyor roller and brushes off the broken glass particles adhering to the discharge conveyor roller. The structure is simple and practical.

[0009] The present invention is further configured as follows: the driving mechanism 1 includes a driving motor 1, a screw rod and a guide rod, the screw rod and the guide rod are respectively rotatably connected to the feeding tracks on both sides of the discharging conveying roller, the driving motor 1 is fixed to the feeding track at the bottom of the discharging conveying roller, the output shaft of the driving motor 1 is transmission-connected to one end of the screw rod, one end of the cleaning rod is threadedly connected to the screw rod through a nut seat, and the other end of the cleaning rod is slidably sleeved on the guide rod through a slider.

[0010] By adopting the above technical solution, a driving motor drives the screw rod to rotate, and the screw rod drives the cleaning rod to move back and forth along the screw rod through the nut seat, and the other end of the cleaning rod moves back and forth synchronously along the guide rod, thereby realizing the cleaning of the discharge conveyor roller.

[0011] The present invention is further configured as follows: a cleaning brush is provided on the top of the cleaning rod.

[0012] By adopting the above technical solution, the discharge conveyor roller is cleaned with a cleaning brush, and the broken glass particles adhering to the surface of the discharge conveyor roller can be brushed off, so that the broken glass particles fall onto the conveyor belt, and at the same time, the outer surface of the discharge conveyor roller will not be worn.

[0014] By adopting the above technical solution, when the conveyor belt moves to the discharge end during rotation, the glass fragments on the conveyor belt are scraped off and collected in the collection box under the action of the fixed scraper. The size of the fixed scraper matches the width of the conveyor belt, which can ensure that all the glass fragments on the conveyor belt are scraped off to avoid omission. The fixed scraper is fixed to the support plate by bolts, so that the fixed scraper and the support plate are detachably connected. After long-term use, when the fixed scraper is worn or the scraping effect is poor, the fixed scraper can be removed and replaced with a new fixed scraper.

At the same time, the movable scraper keeps moving, which can also prevent the broken glass particles from adhering to the outer wall of the movable scraper. The setting of the sliding groove can play a certain limiting role in the movement of the sliding rod, thereby ensuring the movement trajectory of the movable scraper, improving the cleaning and scraping effect of the movable scraper, and preventing the rotation of the sliding rod from affecting the cleaning effect of the movable scraper.
