Description

Technical Field

[0001] This utility model relates to the field of drying oven technology, specifically a drying oven for tempered glass. Background Technology

[0002] Drying is a crucial step in the tempered glass production process. Its purpose is to remove residual moisture or processing fluid from the glass surface, ensuring the quality stability of subsequent tempering, coating, and cutting processes. Currently, most mainstream tempered glass drying equipment on the market adopts an integrated drying oven structure, where multiple pieces of tempered glass are stacked or placed together on trays inside the oven for unified drying. However, this type of equipment has many technical drawbacks in practical applications, making it difficult to meet the demands of efficient and high-quality production. The drying efficiency of existing equipment is low. Uneven airflow distribution inside traditional drying ovens, coupled with the dense placement of glass, leads to insufficient heating and airflow contact on some glass surfaces, resulting in uneven drying. To achieve satisfactory drying results, the drying time needs to be extended, severely restricting production cycle time. Furthermore, the traditional equipment requires opening the entire oven door to handle glass, which not only causes a rapid drop in oven temperature and requires significant energy for reheating but also increases operation time, further reducing production efficiency. Therefore, improvements to existing technology are necessary. Summary of the Invention

[0003] The purpose of this invention is to provide a drying oven for tempered glass to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a tempered glass drying oven, comprising a main body of the oven, wherein operating openings are evenly spaced from bottom to top on the side wall of the main body of the oven, and a slide rail is installed on the inner wall of each operating opening on both sides. A tempered glass support plate is slidably installed in the slide rail, and four glass drying chambers are opened at the top of the tempered glass support plate; a support block is installed at the center of the interior of each glass drying chamber, and a glass suction cup is installed at the top of the support block; drying holes are evenly opened at the bottom of the glass drying chamber; a sealing plate is vertically installed on the front side wall of the tempered glass support plate, and the sealing plate is inserted into the operating opening; guide components are installed on both the left and right sides of the top of the tempered glass support plate; and a locking rod is installed at the center of the front side of the top of the tempered glass support plate.

[0005] As a preferred embodiment of the tempered glass drying oven of this utility model, the guide assembly includes a fixed plate installed on the top of the tempered glass support plate, a compression spring vertically installed on the top of the fixed plate, a universal seat installed on the top of the compression spring, and a universal ball installed inside the universal seat.

[0006] As a preferred embodiment of the tempered glass drying oven of this utility model, the inner wall of the universal seat is provided with rotating cavities evenly spaced along its axis, and ball bearings are installed inside the rotating cavities, with the ball bearings fitting snugly against the universal ball bearings.

[0007] In a preferred embodiment of the tempered glass drying oven of this utility model, a sealing gasket is fitted on the outer wall of the sealing plate, the outer wall of the sealing gasket is fitted against the inner wall of the operating port, and a handle is installed on the outer wall of the sealing plate.

[0008] As a preferred embodiment of the tempered glass drying oven of this utility model, the sealing gasket has a filling cavity inside, an arched elastic plate is installed inside the filling cavity, and the outer wall of the sealing gasket has an adhesive surface.

[0009] As a preferred embodiment of the tempered glass drying oven of this utility model, a support frame is installed at the bottom of the main body of the drying oven, a drying fan is installed at the bottom of the support frame, the output end of the drying fan is connected to the interior of the main body of the drying oven, and an exhaust valve is installed at the top of the main body of the drying oven.

[0010] As a preferred embodiment of the tempered glass drying oven of this utility model, an equipment box is installed on the side wall of the support frame, a drive frame is installed at the bottom of the support frame, and casters are installed at the four corners of the bottom of the drive frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the setting of the tempered glass drying oven has a reasonable structural design; The main side wall of the drying oven features evenly spaced operating openings from bottom to top. Each opening corresponds to an independent tempered glass support plate, and each support plate has four glass drying chambers, allowing for the independent placement of multiple glass panes in layers and zones. This structure allows operators to handle specific layers of glass through a single operating opening without opening the overall oven door, avoiding overall temperature fluctuations within the oven and eliminating the need for repeated heating, significantly shortening the drying cycle and increasing production speed. Simultaneously, the layered design ensures more even airflow across the surface of each glass pane, and combined with the evenly spaced drying holes at the bottom of the glass drying chambers, ensures that hot air directly acts on the glass surface, solving the problem of uneven drying in traditional equipment.

[0014] 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.

[0015] Please see Figure 1-4 This utility model provides a technical solution: In this technical solution, a tempered glass drying oven includes a main body 1. The side walls of the main body 1 are evenly spaced from bottom to top with operation ports 4. Each operation port 4 has a slide rail installed on both inner walls. A tempered glass support plate 5 is slidably installed in the slide rail. Four glass drying chambers 10 are opened at the top of the tempered glass support plate 5. A support block 14 is installed at the center of the glass drying chamber 10. A glass suction cup 13 is installed at the top of the support block 14. Drying holes 15 are evenly opened at the bottom of the glass drying chamber 10. A sealing plate 17 is vertically installed on the front side wall of the tempered glass support plate 5. The sealing plate 17 is inserted into the operation port 4. Guide components 11 are installed on both the left and right sides of the top of the tempered glass support plate 5. A locking rod 12 is installed at the center of the front side of the top of the tempered glass support plate 5.

[0016] In the specific implementation process, the main body 1 of the drying oven, as the core frame of the equipment, is made of high-temperature resistant stainless steel. The inner walls on both sides of each operating port 4 are fixed with sliding rails by welding, allowing the tempered glass support plate 5 to be inserted and removed within the operating port 4. During actual operation, operators can remove and place the glass by pushing and pulling the tempered glass support plate 5. This structure eliminates the need to open the entire oven door; operation is completed simply by pushing and pulling a single-level support plate. Each operation only affects the temperature of a single level, significantly reducing energy consumption and drying cycle. A support block 14 is bolted to the center of the glass drying chamber 10. The support block 14 is made of high-temperature resistant silicone, and the glass suction cup 13 at the top of the support block 14 is a vacuum suction cup, which can firmly adhere and fix the glass, preventing damage during the drying process due to hot air impact or other factors. To prevent slight vibrations that could cause shifting or sliding, the bottom of the glass drying chamber 10 is evenly provided with drying holes 15. This design allows the hot air supplied by the drying fan 8 to be evenly blown to the bottom of the glass through the drying holes 15, while the hot air at the top of the glass can flow upwards, forming a "bottom in, top out" airflow circulation. This ensures that both the upper and lower surfaces of the glass can fully contact the hot air, avoiding the uneven drying problem caused by traditional single-direction airflow. The locking rod 12 installed at the center of the front side of the top of the tempered glass support plate 5 adopts a spring pin structure: the locking rod 12 can move up and down in the vertical direction. When the support plate is pushed back into the furnace, the locking rod 12 is pulled upwards so that its top end is inserted into the pre-set locking hole on the side wall of the drying furnace body 1, thus fixing the position of the support plate. To unlock, the locking rod 12 is pressed downwards to disengage it from the locking hole, and the support plate can be pulled out.

[0017] In some technical solutions, the guide assembly 11 includes a fixing plate 19 installed on the top of the tempered glass support plate 5, a compression spring 20 is vertically installed on the top of the fixing plate 19, a universal seat 21 is installed on the top of the compression spring 20, and a universal ball 22 is installed inside the universal seat 21.

[0018] In the specific implementation process, each tempered glass support plate 5 corresponds to two sets of guide components 11, located on the left and right edges of the four glass drying chambers 10 respectively, ensuring that each piece of glass is guided during placement. The universal seat 21 is a cylindrical structure with a spherical groove inside, ensuring that the universal ball 22 can rotate freely within the groove. When the glass is placed into the glass drying chamber 10, the two edges of the glass contact the universal ball 22. The operator only needs to gently push the glass, and the universal ball 22 will rotate with the direction of glass movement, guiding the glass accurately into the designated position above the support block 14, avoiding edge breakage caused by the glass colliding with the edge of the tempered glass support plate 5. At the same time, the compression spring 20 can automatically compress according to the glass thickness: the greater the glass thickness, the greater the spring compression, and the lower the height of the universal seat 21, always maintaining close contact between the universal ball 22 and the side of the glass, ensuring stable guiding effect.

[0019] In some technical solutions, the inner wall of the universal seat 21 is provided with rotating cavities 23 evenly spaced along its axis, and ball bearings 24 are installed inside the rotating cavities 23, with the ball bearings 24 fitting together with the universal ball 22.

[0020] In the specific implementation process, the inner wall of the universal seat 21 has rotating cavities 23 that are evenly and equidistantly opened along its axis. The rotating cavities 23 are hemispherical. After the ball bearings 24 are installed in the rotating cavities 23, their surfaces are closely attached to the outer wall of the universal ball 22 to form a rolling support structure.

[0021] In some technical solutions, a sealing gasket 16 is fitted on the outer wall of the sealing plate 17, and the outer wall of the sealing gasket 16 is fitted to the inner wall of the operating port 4. A handle 18 is installed on the outer wall of the sealing plate 17.

[0022] In the specific implementation process, the sealing plate 17 is made of the same stainless steel material as the main body 1 of the drying oven. After the tempered glass support plate 5 enters the interior of the main body 1 of the drying oven, the sealing plate 17 can be inserted into the operation port 4 and sealed by the sealing gasket 16. The sealing plate 17 can be easily operated by the handle 18. In some technical solutions, the sealing gasket 16 has a filling cavity 26 inside, an arched elastic plate 27 is installed inside the filling cavity 26, and the outer wall of the sealing gasket 16 is provided with an adhesive surface 25.

[0023] In the specific implementation process, the elasticity of the sealing gasket 16 can be improved by the arched elastic plate 27, and the sealing performance between the sealing gasket 16 and the operating port 4 can be improved by the bonding surface 25.

[0024] In some technical solutions, a support frame 2 is installed at the bottom of the drying oven body 1, a drying fan 8 is installed at the bottom of the support frame 2, the output end of the drying fan 8 is connected to the interior of the drying oven body 1, and an exhaust valve 3 is installed at the top of the drying oven body 1.

[0025] In the specific implementation process, the support frame 2 installed at the bottom of the main body 1 of the drying oven adopts a square tube welded structure, and the drying fan 8 is a high temperature centrifugal fan, which is connected to the air inlet pipe at the bottom of the main body 1 of the drying oven through a flange connection.

[0026] In some technical solutions, an equipment box 9 is installed on the side wall of the support frame 2, a drive frame 6 is installed at the bottom of the support frame 2, and casters 7 are installed at the four corners of the bottom of the drive frame 6.

[0027] In the specific implementation process, the equipment box 9 is made of cold-rolled steel plate, and the surface is sprayed with high temperature resistant and rust-proof paint. The interior is equipped with multiple partitions, which can be used to classify and store the tools required in the drying process. The bottom of the support frame 2 is fixed to the drive frame 6 by welding. The drive frame 6 is a rectangular frame structure. Universal wheels 7 are installed at the four corners of the bottom of the drive frame 6. The universal wheels 7 are heavy-duty polyurethane wheels with braking function.
