Description

Technical Field

[0001] This utility model relates to the field of heat treatment furnace technology, specifically a glass heat treatment furnace. Background Technology

[0002] Glass tunnel heat treatment furnaces are widely used in the production and processing of glass products, mainly for the annealing of architectural glass parts. Through high-temperature treatment, internal stress in glass products can be eliminated, improving the stability and safety of glass products. Some have an upper and lower heating structure, where the conveyor belt ensures that the glass is transported in the center, ensuring that the distance between the upper and lower ends of glass of different thicknesses and the upper and lower heating ends is consistent, thus ensuring uniform heating.

[0003] An investigation revealed that a Chinese utility model patent discloses a tempering furnace for glass heat treatment (publication number: CN218340849U), comprising a tempering support, a conveying roller, a high-temperature tempering chamber, and a cooling chamber. A preheating chamber is located at the front end of the high-temperature tempering chamber, and a waste heat collection chamber is located between the high-temperature tempering chamber and the cooling chamber. The heat from the waste heat collection chamber is transported to the preheating chamber via a fan. A residue conveyor belt for recovering broken glass fragments is located at the bottom of the conveying roller, and a collection bucket is located at the tail end of the residue conveyor belt. This invention can improve the situation of glass material bending deformation and pitting, thereby increasing the glass tempering yield.

[0004] While the aforementioned patents can improve the bending and deformation of glass materials and the appearance of pits, thus increasing the yield of glass tempering, they cannot clean the dust and impurities adhering to the glass surface. When dust enters the high-temperature furnace with the glass, it forms a covering on the glass surface, resulting in an uneven glass surface, affecting its optical performance and appearance quality, and reducing the quality of glass production.

[0005] Therefore, this utility model provides a glass heat treatment furnace to solve the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figure 1-6 As shown, this utility model provides a glass heat treatment furnace, including a body 1, a high-temperature furnace chamber 11 is provided on the top of the body 1, and a roller conveyor belt 12 is provided inside the upper part of the body 1.

[0033] The cleaning component 2 includes a support cover 21, which is fixedly connected to the feed end of the roller conveyor belt 12. A cleaning tank 22 is provided inside the support cover 21. A first silicone scraper 23 is vertically mounted on the upper half of the cleaning tank 22, and a second silicone scraper 24 is vertically mounted on the lower half of the cleaning tank 22. The first and second silicone scrapers 23 and 24 are used for scraping and cleaning the upper and lower surfaces of the glass. A lifting component 3 and an adjusting component 4 are also included. The lifting component 3 is used to adjust the height of the second silicone scraper 24 and the distance between the first and second silicone scrapers 24. Through the arrangement of the first and second silicone scrapers 23 and 24, the upper and lower surfaces of the glass can be scraped, thereby removing impurities from the glass surface and ensuring the surface quality of the glass entering the high-temperature furnace chamber 11. This improves the quality of glass heat treatment and prevents dust from affecting and reducing the quality of the glass after heat treatment.

[0034] Furthermore, guide shafts 25 slide through both ends of the first silicone scraper 23 and the second silicone scraper 24, and the guide shafts 25 are fixedly connected to the inner wall of the support cover 21. Guide rollers 26 are rotatably provided at both corners of the first silicone scraper 23 and the second silicone scraper 24, and the guide rollers 26 rotatably abut against the inner wall of the support cover 21. The guide shafts 25 are mainly used to guide and limit the vertical displacement of the first silicone scraper 23 and the second silicone scraper 24. At the same time, the rotational contact between the guide rollers 26 and the inner wall of the support cover 21 further guides the vertical displacement of the first silicone scraper 23 and the second silicone scraper 24. The rotational contact reduces the sliding friction resistance and ensures the stability of the vertical adjustment of the first silicone scraper 23 and the second silicone scraper 24.

[0035] Furthermore, both ends of the first silicone scraper 23 and the second silicone scraper 24 are fixedly connected to a scale pointer 27. The support cover 21 has a sliding groove corresponding to the scale pointer 27, and the edge of the sliding groove is provided with scale lines. Through the cooperation of the scale lines and the scale pointer 27, the adjustment position of the first silicone scraper 23 or the second silicone scraper 24 can be determined, thereby determining the spacing size according to the height of the first silicone scraper 23 and the second silicone scraper 24.

[0036] Furthermore, the lifting assembly 3 includes a main shaft 31, a worm gear 32 fixedly connected to the outer wall of the main shaft 31, a worm wheel 33 meshing with the outside of the worm gear 32, a nut assembly 34 fixedly connected to the center of the worm wheel 33, a lead screw 35 connected to the center of the nut assembly 34, the top of the lead screw 35 fixedly connected to the bottom of the second silicone scraper 24, a support frame 36 connected to the outer wall of the nut assembly 34 via ball bearings, and the support frame 36 fixedly connected to the inner wall of the support cover 21 by screws, the two ends of the support cover 21 being rotatably connected to the support cover 21 via ball bearings, and handwheels connected to the two ends of the main shaft 31 extending to the outside of the support cover 21. By rotating the main shaft 31, the worm gear 32 is driven to rotate, and further, the meshing of the worm gear 32 and the worm wheel 33 drives the nut assembly 34 to rotate, thereby realizing the up-and-down adjustment of the lead screw 35. When the lead screw 35 moves up and down, the height of the second silicone scraper 24 can be adjusted, thus realizing the height adjustment of the second silicone scraper 24.

[0037] Furthermore, the adjustment component 4 includes a support shaft 41, which is fixedly connected to the inner wall of the support cover 21. A gear 42 is rotatably connected to the outside of the support shaft 41. A first rack 43 meshes with one side of the gear 42, and a second rack 44 meshes with the other side of the gear 42. The adjustment component 4 is provided in two sets, and the two sets of adjustment components 4 are symmetrically distributed at both ends of the first silicone scraper 23 and the second silicone scraper 24. The first rack 43 is fixedly connected to the outer wall of the second silicone scraper 24, and the second rack 44 is fixedly connected to the outer wall of the first silicone scraper 23. The lifting component 3 adjusts the height of the second silicone scraper 24 while simultaneously moving the first rack 43 up and down. When the first rack 43 moves, it drives the support shaft 41 to rotate, which in turn drives the second rack 44 to adjust up and down. Thus, the position of the first silicone scraper 23 can be adjusted while the position of the second silicone scraper 24 is adjusted. The two are centrally matched, effectively adapting to the centrally located conveyor roller for cleaning glass of different thicknesses.

[0038] Working principle: First, an external conveyor frame is installed at the end of the machine body 1. At the same time, the height of the roller conveyor belt 12 and the conveyor frame are adjusted to ensure that the glass is conveyed in the center and that the distance between the upper and lower surfaces of the glass and the upper and lower heating ends of the high-temperature furnace chamber 11 is consistent. When the glass passes through the cleaning tank 22, impurities on the glass surface are scraped off by the upper and lower first silicone scrapers 23 and the second silicone scraper 24 to ensure the surface quality of the glass when it enters the high-temperature furnace chamber 11, thereby improving the heat treatment quality of the glass and avoiding the influence of impurities on the glass quality.

[0039] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
