Description

Technical Field

[0001] This utility model relates to the field of glass processing equipment technology, and in particular to a wind guide device for a tempering furnace used in tempered glass production. Background Technology

[0002] Currently, with increasing demands for safety and mechanical performance in architectural glass, tempered glass has become a key material in building exterior walls, curtain walls, and the home appliance industry. The tempering process typically combines high-temperature heating with rapid cooling to create permanent compressive stress on the glass surface, thereby enhancing its impact and thermal shock resistance. In this process, the airflow system of the tempering furnace, as the core structure of the cooling section, plays a decisive role in the airflow velocity, direction, and temperature uniformity, directly affecting the quality stability and yield of the finished glass. Therefore, the structural design of the airflow device, the airflow organization method, and the clamping method with the glass have become key concerns in the technological development of tempering equipment.

[0003] Regarding the aforementioned issues, most existing tempering furnaces employ fixed air ducts or adjustable air vanes to distribute and regulate airflow. Air is delivered into the furnace's air guide chamber by an external fan, rectified, and then blown onto the glass surface for rapid cooling. Simultaneously, some equipment is equipped with filters or metal screens for primary air filtration to reduce dust particles entering the tempering chamber. The glass is typically positioned by fixed blocks or flexible support plates to prevent movement under wind impact.

[0004] However, existing air guiding devices still have several shortcomings in actual operation. First, the filtration system has a simple structure, which usually makes it difficult to continuously clean a large filtration area. The accumulation of impurities can easily cause airflow turbulence and affect the cooling effect. Second, cleaning is mostly done manually, resulting in frequent equipment interruptions, high maintenance costs, and low efficiency. Third, the clamping structure is rigidly fixed, making it impossible to flexibly adapt to the glass thickness, inconvenient to install, and prone to glass displacement due to unstable clamping, affecting the uniformity of tempering.

[0005] To address the above problems, a drafting device for a tempering furnace used in tempered glass production is proposed. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides an air guide device for a tempering furnace used in tempering glass production, aiming to solve the problems of incomplete air filtration and cleaning in existing air guide devices for tempering furnaces used in tempering glass production, and the lack of a suitable way to fix the glass to be processed.

[0020] As a further description of the above technical solution:

[0021] A scraper is installed between the two threaded rods, and a filter plate is installed inside the cleaning box. The bottom of the scraper is slidably connected to the top of the filter plate.

[0030] 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.

[0031] Reference Figure 1 - Figure 3 This utility model provides an embodiment of an air guiding device for a tempering furnace used in tempered glass production. The device includes a housing 1, which is generally rectangular in shape and forms the air guiding and heating space of the tempering furnace. A cleaning box 2 is fixedly installed on the top of the housing 1. Multiple intake fans 4 are installed on the top wall of the cleaning box 2 to draw in external air and introduce it into the system for heat exchange and air circulation. The multiple intake fans 4 are evenly distributed along the top of the cleaning box 2 to ensure a balanced airflow velocity. Two collection boxes 3 are symmetrically arranged on the left and right sides of the cleaning box 2, corresponding to the movement trajectory of the cleaning components 8, for the centralized collection of impurities and dust, maintaining the cleanliness and efficient operation of the cleaning system. A heater 5 is installed on the rear interior of the housing 1 to preheat the incoming airflow or maintain the internal temperature of the furnace cavity to meet the heating environment required for tempered glass. The cleaning components 8 are installed inside the cleaning box 2, which can effectively clean the filter structure, ensuring the continuity of air filtration and thus improving the overall operating efficiency of the air guiding device. Furthermore, two clamping mechanisms 6 are symmetrically installed inside the housing 1 to provide elastic limit adjustment according to the glass thickness, thereby improving the adaptability and stability of clamping.

[0032] Reference Figure 1 - Figure 3 The clamping mechanism 6 is located on the left and right sides inside the housing 1, respectively for firmly clamping and guiding the installation of tempered glass. The clamping mechanism 6 includes two opposing outer shells 61. The opposite sides of the two outer shells 61 are fastened to the inner wall of the housing 1 by a fixing connector, forming a stable support base. Each outer shell 61 has two symmetrically arranged clamping components 62 inside, used to clamp the glass workpiece placed between the two mechanisms, ensuring that it does not shift or tilt under the action of high-temperature airflow. The core component of the clamping component 62 is the clamping plate 625, which is made of high-strength heat-resistant material, suitable for the high-temperature working environment of the tempering furnace. Multiple guide posts 624 are installed horizontally side-by-side inside the plate, evenly distributed, to limit and guide the glass during insertion, ensuring that the glass slides smoothly into and aligns with the clamping area, improving loading efficiency and installation accuracy. The clamping plate 625 is also equipped with multiple T-shaped limiting plates 621 on the side near the outer shell 61. The T-shaped limiting plates 621 are slidable in the vertical direction and are respectively inserted into the T-shaped grooves 623 provided inside the outer shell 61. The internal space of the T-shaped grooves 623 accommodates adjusting springs 622. The adjusting springs 622 are located between two T-shaped limiting plates 621. When the T-shaped limiting plates 621 are pushed by external force, they are compressed to generate elastic restoring force, thereby forming a buffer-type clamping effect on the limiting plates, ensuring good adaptability to glass thickness and preventing the glass from shaking or being poorly clamped due to dimensional deviations.

[0033] Reference Figure 1 - Figure 3 The cleaning component 8 is mainly located inside the cleaning box 2 and is used to periodically remove dust and impurities accumulated on the surface of the filter plate 7 to ensure the cleanliness of the introduced air and improve the overall system operating efficiency. The cleaning component 8 includes two threaded rods 806 arranged parallel to each other on both sides of the inside of the cleaning box 2. The threaded rods 806 are fixed to the inner wall of the corresponding collection box 3 by an outer mounting plate 805, ensuring stable installation and easy maintenance. A scraper 807 is horizontally arranged between the two threaded rods 806. The bottom of the scraper 807 is slidably connected to the top of the filter plate 7 installed inside the cleaning box 2, and can move left and right along the surface of the filter plate 7 to scrape off dust particles and impurities. The scraper 807 is typically made of elastic or flexible material, ensuring thorough cleaning without causing wear to the surface of the filter plate 7. A worm gear 804 is installed at one end of each threaded rod 806, meshing with worms 802 located at both ends of the connecting rod 801. The worms 802 are driven to rotate by a drive motor 803 located outside the collection box 3. The output shaft of the drive motor 803 is fixedly connected to the connecting rod 801. The connecting rod 801 and the two threaded rods 806 are arranged perpendicularly and cross each other. Its rotation drives the worm gear 802 to move synchronously. Thus, through the worm wheel 804 and worm gear 802 transmission mechanism, the threaded rods 806 on both sides rotate synchronously, thereby driving the scraper 807 installed on it to move laterally along the surface of the filter plate 7.

[0034] Working Principle: During operation, the device first draws external air into the cleaning chamber 2 via multiple intake fans 4 at the top. The air undergoes initial filtration through a filter plate 7 installed inside the cleaning chamber 2. A sliding scraper 807 is mounted above the filter plate 7, with its bottom slidably connected to the top of the filter plate 7 to remove surface impurities. The scraper 807 is connected between two threaded rods 806 on either side. The threaded rods 806 are fixed to the inner wall of the collection chamber 3 via mounting plates 805. One end of each threaded rod 806 is connected to a worm gear 804, which meshes with worms 802 installed at both ends of a connecting rod 801. The connecting rod 801 is vertically connected to the threaded rods 806 and is driven to rotate by a drive motor 803 on the outside of the collection chamber 3, thereby causing the scraper 807 to reciprocate and clean the filter plate 7. The filtered air flows inside the chamber 1 and is heated by a heater 5 installed at the rear of the chamber 1. The heated air is then used in the tempering process. Two clamping mechanisms 6 are symmetrically installed inside the housing 1. Each clamping mechanism 6 consists of a housing 61 fixed to the inner wall of the housing 1. A clamping assembly 62 is installed inside the housing 61. The clamping plates 625 in the clamping assembly 62 are arranged opposite to each other. Multiple guide posts 624 are arranged side by side in the clamping plate 625 for positioning the glass. Multiple T-shaped limiting plates 621 are provided on the side near the housing 61. The T-shaped limiting plates 621 are slidably connected in the T-shaped grooves 623 opened in the housing 61. An adjusting spring 622 is provided between two T-shaped limiting plates 621 to form an elastic support structure when the glass is inserted, so that the glass to be processed is guided and firmly clamped between the two clamping mechanisms 6, and finally the entire process of air guiding and tempering auxiliary functions is completed.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
