Description

Technical Field

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

[0002] During the production and processing of glass, especially in the manufacturing of automotive windshields, architectural curtain wall glass, and coated glass, a cleaning process is usually required to remove surface impurities and stains. If the water in the cleaned glass cannot be completely removed in a short time, water droplets or water films will remain on the glass surface. This will not only cause bubbles and watermarks in subsequent processes such as coating, lamination, and heat treatment, but will also affect the optical properties and adhesion of the coating layer, thus causing product defects.

[0003] Existing glass drying equipment mostly uses blowers or centrifugal fans to generate high-pressure airflow, which is then blew and dried along the glass conveying path by air knives. These devices can meet the drying requirements to a certain extent for ordinary, uncoated glass. However, when dealing with coated glass, due to the extremely high requirements for surface cleanliness and drying effect of the coating layer, existing drying methods have the following shortcomings: Traditional air knives are mostly fixed in a single direction, usually perpendicular to the glass conveying direction. Although this method can initially remove large areas of water film, there are often drying dead zones at the edges, corners, and flow ends of the glass where the airflow cannot fully cover, making it difficult to completely remove residual water droplets. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a glass drying device that can effectively remove residual water droplets from the edges of glass.

[0010] In some embodiments, the air outlet blade is an alloy blade with an adjustable opening, and the adjusting component is an adjusting bolt, which is assembled and connected to both sides of the air outlet blade.

[0011] In some embodiments, the housing assembly includes an upper housing and a lower housing that are assembled together; the upper housing and the lower housing enclose the cavity; The conveying assembly is located between the upper housing and the lower housing; a plurality of air knife assemblies are symmetrically arranged on both sides of the conveying assembly along the height direction and are respectively assembled and connected to the upper housing and the lower housing.

[0017] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0018] In existing technologies, traditional air knives mostly operate in a fixed, single-direction blowing pattern, typically perpendicular to the glass conveying direction. While this method can initially remove large areas of water film, "drying dead zones" often exist at the edges, corners, and flow tails of the glass, where the airflow cannot adequately cover them, making it difficult to completely remove residual water droplets. To address these issues, a glass drying device is provided; please refer to [reference needed]. Figure 1 as well as Figure 2 ,include: A housing assembly having a cavity 1 therein; The conveying assembly 2 is located at least partially inside the cavity 1 and is used to transport glass. An air knife assembly 3 is assembled and connected to the cavity 1; there are at least two air knife assemblies 3, and the blowing direction of the air knife assembly 3 is towards the conveying assembly 2; wherein, the blowing direction of at least one air knife assembly 3 is perpendicular to the conveying direction of the conveying assembly 2; the blowing direction of at least one air knife assembly 3 is inclined relative to the conveying direction of the conveying assembly 2.

[0019] As described above, the beneficial effects of this invention are as follows: by setting a conveying component 2 inside the cavity and arranging multiple air knife components 3 around it, the glass can be swept by airflow from multiple angles and directions during the conveying process. At least one air knife component 3 has its sweeping direction perpendicular to the conveying direction, ensuring a high-impact lateral airflow on the glass surface to quickly remove large areas of residual water film. Meanwhile, at least one air knife component 3 is arranged at an angle, creating a combined effect of tangential and longitudinal airflow, especially at glass edges, corners, and flow tails, effectively removing residual water droplets and avoiding drying dead zones. Through the combined arrangement of vertical and inclined air knives, targeted removal of moisture from different locations is achieved, ensuring uniform drying of the glass surface and efficiently meeting the high cleanliness requirements of coated glass production.

[0020] Preferably, the conveying component 2 consists of conveying rollers arranged sequentially according to a preset direction and spatial arrangement. The glass product comes into contact with the conveying rollers, and the glass is conveyed by the rotation of the conveying rollers.

[0021] Preferably, the number of air knife components 3 is three; the blowing direction of two air knife components 3 is perpendicular to the conveying direction of the conveying component 2; and the blowing direction of one air knife component 3 is inclined relative to the conveying direction of the conveying component 2. That is, two air knife components perpendicular to the conveying direction are used to quickly remove large areas of residual water film, and then an inclined air knife component is used to remove residual water droplets from the glass edge. According to experimental statistics, this can achieve a good drying effect on the glass surface.

[0022] Please refer to Figure 3 In some embodiments, the cavity includes two opposing clamping plates 11, which are fixedly connected to the inner wall of the cavity 1 and are arranged parallel to the horizontal plane; the air knife assembly 3 is assembled and connected to the clamping plates 11.

[0023] As described above, the symmetrical clamping plates 11 installed within the cavity and fixed to the inner wall of the cavity provide a stable installation reference, allowing for more precise assembly of the air knife assembly 3. The clamping plates 11, arranged parallel to the horizontal plane, help maintain the symmetry of the air knife assembly 3 on both sides of the glass's running path, ensuring a balanced distribution of the purging airflow and preventing inconsistent drying effects on the left and right sides of the glass. Furthermore, the parallel arrangement of the clamping plates 11, as a load-bearing component, facilitates later maintenance and replacement of the air knife, improving the overall stability and maintainability of the equipment.

[0024] Please refer to Figure 3 In some embodiments, the card plate 11 is provided with U-shaped slots 12 arranged at preset intervals, and the air knife assembly 3 is engaged with the U-shaped slots 12.

[0025] As described above, by opening U-shaped slots 12 with preset spacing on the clamping plate 11, the air knife assembly 3 can be quickly installed and positioned by snap-fit. This structure can be fixed without complex fasteners, making it easy to adjust or replace according to different glass specifications during production, significantly shortening the debugging time. The preset spacing of the U-shaped slots 12 ensures that the distance between the air knives is consistent, making the blowing airflow cover uniform and helping to achieve comprehensive drying of the glass surface.

[0026] Please refer to Figure 4 In some embodiments, the inclined air knife assembly 3 is positioned near the end of the conveying assembly 2.

[0027] As described above, the inclined air knife assembly 3, positioned at the end of the conveying assembly 2, enables a secondary, enhanced purging process as the glass is about to leave the drying chamber. This structure utilizes the inclined airflow to concentrate and remove moisture from the glass's tail end, preventing water droplets from remaining on the glass upon exiting the chamber and thus avoiding secondary contamination from subsequent environmental airflow or handling. Furthermore, the inclined purging at the end is particularly effective at drying edges and corners, ensuring consistent drying quality across the entire glass surface.

[0028] Please refer to Figure 2 and Figure 5 In some embodiments, the housing assembly includes an upper housing 13 and a lower housing 14 that are assembled together; the upper housing 13 and the lower housing 14 form a cavity; The conveying assembly 2 is located between the upper housing 13 and the lower housing 14; multiple air knife assemblies 3 are symmetrically arranged on both sides of the conveying assembly 2 along the height direction and are respectively assembled and connected to the upper housing 13 and the lower housing 14.

[0029] As described above, the cavity is assembled from an upper shell 13 and a lower shell 14, with the conveying assembly 2 located between them, enabling the glass to move within the enclosed cavity. Figure 11 Multiple air knife components 3 are symmetrically distributed along the height direction on both sides of the conveying component 2 and fixed to the upper and lower housings 14 respectively. This design forms an all-around enveloping airflow, which can simultaneously blow air from both the upper and lower sides of the glass. At the same time, although gas flow occurs at the junction of the conveying component 2 and the cavity, the blowing process of the air knife components 3 within the cavity formed by the upper and lower housings 14 maintains a positive pressure inside the cavity relative to the outside, thereby preventing external gas from mixing into the cavity, effectively reducing the risk of external dust contamination, and preventing damage to the glass during the blowing process.

[0030] Please refer to Figure 5 In some embodiments, a silencer box 131 is provided on the top of the upper housing 13, and a sealing strip 15 is provided at the assembly connection between the upper housing 13 and the lower housing 14.

[0031] As described above, the addition of a silencer box 131 to the top of the upper housing 13 can absorb the noise generated by the fan and air knife during operation, improve the production environment, reduce auditory interference to workers, and meet the requirements of green production. Meanwhile, a sealing strip 15 is installed at the connection between the upper and lower housings 14, effectively preventing airflow leakage and water vapor overflow, ensuring the stability of the internal air circulation system, and improving the level of air cleanliness control.

[0032] Please refer to Figure 6 and Figure 7 In some embodiments, the air knife assembly 3 includes an air duct 31, an air outlet 32, and an adjusting member 33; the air duct 31 is assembled and connected to the cavity, the air outlet 32 ​​is connected to the air duct 31, and the adjusting member 33 is movably connected to the air outlet 32 ​​and is used to adjust the opening of the air outlet 32.

[0033] As described above, the assembly and connection between the air duct 31 and the cavity ensures a stable delivery of high-pressure airflow to the blade edge. The air outlet blade 32, as the final airflow outlet, has an adjustable opening that allows for flexible control of the airflow volume and speed to adapt to glass of different thicknesses and shapes. The adjusting component 33 provides a precise control method, enabling the air outlet to be flexibly adjusted according to process requirements. Overall, this structure ensures controllable drying effects and process adaptability.

[0034] Please refer to Figure 6 and Figure 7In some embodiments, the air outlet blade 32 is an alloy blade with adjustable opening, and the adjusting member 33 is an adjusting bolt, which is assembled and connected to both sides of the air outlet blade 32.

[0035] As described above, the air outlet blade 32 uses an alloy blade, ensuring high strength and wear resistance, and preventing deformation during long-term operation. Simultaneously, the blade opening is adjustable, allowing for flexible settings of the airflow distribution according to the cleaning and drying needs of different types of glass. Adjusting bolts are connected to both sides of the blade, enabling precise control of the blade gap through threaded adjustment, thus ensuring that the airflow distribution meets expectations and guarantees a stable and consistent drying effect on the glass surface.

[0036] Please refer to Figure 8 and Figure 9 In some embodiments, it also includes a dehumidification assembly 4, a filter assembly 5, and a fan assembly 6; the dehumidification assembly 4 is connected to the cavity pipeline, the filter assembly 5 is connected to the dehumidification assembly 4 pipeline, the fan assembly 6 is connected to the filter assembly 5 pipeline, and the fan assembly 6 is connected to the air knife assembly 3 pipeline.

[0037] As described above, the equipment is further equipped with a dehumidification component 4, a filter component 5, and a fan component 6, forming an internal air circulation purification system. During the circulation process, the purge airflow passes through the dehumidification component 4 to remove moisture, preventing the repeated use of humid air and thus reducing drying efficiency; it passes through the filter component 5 to remove dust and particulate matter, preventing secondary contamination of the glass; and the fan component 6 provides continuous and stable power to maintain the delivery of high-pressure airflow. This circulation system ensures that the airflow within the cavity remains dry and clean at all times, significantly improving the cleanliness and production qualification rate of the coated glass.

[0038] Please refer to Figure 4 In some embodiments, the angle between the blowing direction of at least one air knife assembly 3 and the conveying direction of the conveying assembly 2 is in the range of 55°-60°.

[0039] As described above, limiting the angle between the inclined air knife assembly 3 and the conveying direction to 55°-60° is the optimal range verified through extensive experiments. Within this angle range, the airflow maintains sufficient impact force while forming an effective tangential airflow, enhancing the removal of residual water droplets from the glass surface. Particularly at the glass edge, the triangular airflow coverage area gradually shrinks, forcing water droplets towards the edge and completely removing them. This angle range ensures an optimal balance between drying efficiency and energy consumption.

[0040] Embodiment 1 of this utility model is as follows: Please refer to Figures 1 to 5A glass drying device includes a cavity 1 enclosed by a housing assembly, a conveying assembly 2 located at least partially inside the cavity for transporting glass, and air knife assemblies 3 assembled and connected to the cavity. Three pairs of air knife assemblies 3 are symmetrically distributed on both sides of the conveying assembly 2, with three air knives on each side, for a total of six. The blowing direction of the air knife assemblies 3 faces the conveying assembly 2. At least one pair of air knife assemblies 3 has a blowing direction perpendicular to the conveying direction of the conveying assembly 2, forming a high-impact transverse airflow on the glass surface. At least one pair of air knife assemblies 3 has an inclined blowing direction relative to the conveying direction of the conveying assembly 2, located near the end of the conveying assembly 2, with an angle between the inclined blowing direction and the conveying direction ranging from 55° to 60°. This arrangement creates a combined tangential and longitudinal effect, particularly enhancing drying at glass edges, corners, and tail ends.

[0041] Please refer to Figure 3 The cavity includes two symmetrically arranged retaining plates 11, which are fixedly connected to the inner wall of the cavity and are parallel to the horizontal plane. Three pairs of air knife assemblies 3 are respectively assembled and connected to the retaining plates 11. Preferably, the retaining plates 11 are provided with U-shaped slots 12 arranged at preset intervals, and the air knife assemblies 3 are engaged with the U-shaped slots 12, thereby realizing the rapid installation and positioning of the air knife assemblies 3.

[0042] Please refer to Figure 2 and Figure 5 The housing assembly consists of an upper housing 13 and a lower housing 14, with the conveying assembly 2 located between the upper housing 13 and the lower housing 14. For example... Figure 11 Three pairs of air knife assemblies 3 are symmetrically arranged on both sides of the conveying assembly 2 along the height direction, and are respectively assembled and connected to the upper housing 13 and the lower housing 14 to form a bidirectional enveloping airflow. When the glass is running, the first two pairs of air knife assemblies 3 perform preliminary blowing on the glass in a vertical manner, while the third pair of inclined air knife assemblies 3 is located at the end of the conveying assembly 2 for secondary enhanced blowing to ensure that the glass is completely dry before leaving the cavity.

[0043] Please refer to Figure 5 The top of the upper housing 13 is provided with a silencer box 131 to reduce the noise when the air knife is running; a sealing strip 15 is provided at the assembly connection between the upper housing 13 and the lower housing 14 to prevent air leakage and water vapor overflow, and to maintain stable airflow inside the cavity.

[0044] Please refer to Figure 6 and Figure 7The air knife assembly 3 includes an air duct 31, an air outlet blade 32, and an adjusting component 33. The air duct 31 is assembled and connected to the cavity, the air outlet blade 32 communicates with the air duct 31, and the adjusting component 33 is movably connected to the air outlet blade 32 and used to adjust the opening degree of the air outlet blade 32. Preferably, the air outlet blade 32 is an alloy blade with an adjustable opening degree, and the adjusting component 33 is an adjusting bolt. The adjusting bolt is assembled and connected to both sides of the air outlet blade 32 respectively, so as to achieve precise control of the air outlet gap through thread adjustment.

[0045] Please refer to Figure 8 and Figure 9 The glass drying equipment also includes a dehumidification component 4, a filter component 5, and a fan component 6. The dehumidification component 4 is connected to the cavity pipeline and is used to dehumidify the return air. The filter component 5 is connected to the dehumidification component 4 pipeline and is used to remove particulate matter and impurities from the air. The fan component 6 is connected to the filter component 5 pipeline and is connected to the air knife component 3 pipeline to provide a continuous and stable high-pressure airflow for the air knife.

[0046] Please refer to Figure 10 Preferably, the filter assembly 5 and the fan assembly 6 are disposed inside the air box 7. The top of the air box 7 has an air inlet 71 and is connected to the dehumidification assembly 4 through the air inlet 71. The filter assembly 5 consists of two layers of filter media, namely a medium-efficiency filter media and a high-efficiency filter media, which are disposed in the air box 7 near the air inlet 71. The air box 7 is provided with a filter media insertion port 72, and the medium-efficiency filter media and the high-efficiency filter media are respectively disposed in independent cavities through the insertion port 72. The blower assembly 6 is a blower located in the air box 7 on the side of the filter medium away from the air inlet 71. The blower absorbs the filtered gas from the filter medium and outputs the airflow through the pipeline to the air knife assembly 3.

[0047] With the above structure, as the glass moves on the conveying assembly, three pairs of air knife assemblies, arranged vertically and at an angle, achieve multi-angle, multi-stage high-pressure airflow purging. The cavity, formed by the upper and lower shells, is a closed space, and with the help of sealing strips and a silencer box, it ensures the cleanliness of the cavity interior and low operating noise. The air knife assemblies are quickly assembled via U-shaped slots, and the opening of the alloy blades is adjusted by adjusting bolts, thus adapting to different glass sizes and thicknesses. During airflow circulation, dehumidification and filtration components ensure the dryness and cleanliness of the airflow, while the fan assembly ensures the power output of the airflow. Overall, this equipment can efficiently dry the glass while ensuring the cleanliness of the glass surface and avoiding secondary contamination, making it particularly suitable for the high-standard production requirements of coated glass. The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
