Description

Technical Field

[0001] The utility model relates to the technical field of convection leveling tempering furnaces, in particular to a glass collecting device for convection leveling tempering furnaces. Background Art

[0002] A tempering furnace is a device that produces tempered glass using physical or chemical methods. It includes physical glass tempering equipment and chemical glass tempering equipment. Physical glass tempering equipment heats flat glass and then rapidly cools it, creating compressive stress on the surface of the cooled glass and tensile stress inside the glass, thereby increasing the strength of the glass and turning ordinary annealed glass into tempered glass. Chemical tempering equipment increases the strength of the glass by changing the chemical composition of the glass surface, using methods such as surface dealkalization and alkali metal ion exchange.

[0003] However, in the prior art, when the leveling tempering furnace is processing tempered glass, part of the tempered glass will be broken during processing, and the broken fragments will remain inside the leveling tempering furnace, which will affect the processing of the subsequent tempered glass. In addition, the broken tempered glass is located inside the leveling tempering furnace, which is very inconvenient to clean. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a glass collecting device for a convection leveling tempering furnace.

[0005] In order to solve the above technical problems, the technical solution of the utility model is:

[0006] A convection leveling tempering furnace glass collection device includes a tempering furnace, wherein both ends of the tempering furnace are provided with an inlet and outlet, and the heights of the two inlet and outlet are flush; a plurality of rolling transmission rollers are rotatably installed inside the tempering furnace; a support bar is provided below the transmission roller, and the support bar is fixed inside the tempering furnace, and a plurality of electric telescopic rods are fixed on the upper surface of the support bar; a rotating sealing plate is installed above the electric telescopic rod; a supporting shaft is fixedly inserted through one side of the rotating sealing plate; both ends of the supporting shaft are inserted into the tempering furnace and connected to the tempering furnace through roller bearings; two supporting base plates are fixed to the bottom of the tempering furnace, and a conveyor belt is provided between the two supporting base plates.

[0007] Preferably, the upper surface of the rotary sealing plate is an inclined surface, and two supporting blocks are fixed to the upper surfaces of both ends of the rotary sealing plate.

[0008] Preferably, a guide rail is fixed to the upper surface of the support block, and a guide groove is provided on the inner side of the guide rail.

[0009] Preferably, a moving rod is provided between the two guide rails located above the same rotating sealing plate, and both ends of the moving rod are plugged with positioning plug rods, and one end of the positioning plug rod is slidably engaged with the inner side of the guide slide groove.

[0010] Preferably, a cleaning scraper is fixed to the bottom surface of the movable rod, and the bottom surface of the cleaning scraper is in contact with the upper surface of the rotating sealing plate and in sliding contact with the rotating sealing plate.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. When the glass inside the tempering furnace is broken, the end of the electric telescopic rod is retracted. At this time, the rotary sealing plate moves downward under the action of gravity and rotates around the positioning plug rod, so that the bottom of the tempering furnace is opened, and the broken glass is guided to the conveyor belt and transported to the end of the tempering furnace through the conveyor belt. This realizes the rapid cleaning of the broken glass inside the tempering furnace without affecting the subsequent processing of the tempered glass.

[0013] 2. A sliding moving rod and a cleaning scraper are installed on the surface of the rotating sealing plate. After the rotating sealing plate is rotated and opened, the cleaning scraper slides on the inside of the two guide rails driven by the positioning plug-in rod, so that the cleaning scraper slides along the surface of the rotating sealing plate to prevent broken steel glass fragments from remaining on the surface of the rotating sealing plate.

[0019] The following further describes specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the descriptions of these embodiments are intended to aid understanding of the present invention and do not constitute limitations on the present invention. Furthermore, the technical features involved in the various embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0020] like Figure 1 and Figure 2 As shown, both ends of the tempering furnace 1 are provided with an inlet and outlet 2, and the heights of the two inlet and outlet 2 are flush. A plurality of rolling transmission rollers 5 are rotatably installed inside the tempering furnace 1, and a support bar 6 is provided below the transmission roller 5. The support bar 6 is fixed inside the tempering furnace 1, and a plurality of electric telescopic rods 7 are fixed on the upper surface of the support bar 6. A rotating sealing plate 8 is installed above the electric telescopic rod 7. A supporting shaft 11 is fixedly inserted through one side of the rotating sealing plate 8. Both ends of the supporting shaft 11 are inserted into the tempering furnace 1 and connected to the tempering furnace 1 through roller bearings. Two supporting base plates 3 are fixed to the bottom of the tempering furnace 1, and a conveyor belt 4 is provided between the two supporting base plates 3. The rotating sealing plate 8 is supported by the electric telescopic rod 7 so that the rotating sealing plate 8 remains level with the ground, and adjacent rotating sealing plates 8 contact each other, so that multiple rotating sealing plates 8 form a plate-like structure at the bottom of the tempering furnace 1 to seal the bottom of the tempering furnace 1 and prevent heat from leaking out of the tempering furnace 1.

[0021] As the preferred technical solution of this embodiment, Figure 3 and Figure 4 As shown, the upper surface of the rotating sealing plate 8 is a slope, and two support blocks 14 are fixed to the upper surfaces of both ends of the rotating sealing plate 8. The inclination of the upper surface of the rotating sealing plate 8 can guide the broken tempered glass toward the moving rod 9, so that the tempered glass can be completely removed from the rotating sealing plate 8 when the moving rod 9 and the cleaning scraper 10 move subsequently.

[0022] In this embodiment, a guide rail 13 is fixed to the upper surface of the support block 14, and a guide groove is provided on the inner side of the guide rail 13. A moving rod 9 is provided between the two guide rails 13 located above the same rotating sealing plate 8, and both ends of the moving rod 9 are plugged with positioning plug rods 12. One end of the positioning plug rod 12 is slidably engaged with the inner side of the guide groove, and the positioning plug rod 12 is used to support the moving rod 9 located between the two guide rails 13, so that the end of the moving rod 9 is in contact with the guide rail 13 and can slide between the two guide rails 13.

[0023] A cleaning scraper 10 is fixed to the bottom surface of the movable rod 9. The bottom surface of the cleaning scraper 10 is in contact with the upper surface of the rotating sealing plate 8 and is in sliding contact with the rotating sealing plate 8. When the movable rod 9 slides, the cleaning scraper 10 is used to clean the tempered glass fragments on the surface of the rotating sealing plate 8 to prevent the tempered glass fragments from remaining on the surface of the rotating sealing plate 8.

[0024] Working principle: When the tempered glass is broken during the processing inside the tempering furnace 1, the tempered glass fragments pass through the gap between the adjacent transmission rollers 5 and fall on the surface of the rotating sealing plate 8. At this time, the electric telescopic rod 7 is energized and the movable end is recovered. Since the movable end of the electric telescopic rod 7 supports the bottom of the rotating sealing plate 8, when the movable end of the electric telescopic rod 7 is recovered, the rotating sealing plate 8 rotates downward around the axis of the support shaft 11 under the influence of gravity. When the rotating sealing plate 8 rotates and the inclination angle gradually increases, the moving rod 9 drives the positioning plug rod 12 to slide along the inner side of the guide rail 13. At this time, the cleaning scraper 10 slides against the surface of the rotating sealing plate 8 driven by the moving rod 9. The sliding cleaning scraper 10 sweeps the tempered glass fragments on the surface of the rotating sealing plate 8 onto the surface of the conveyor belt 4. Then the conveyor belt 4 is energized and transports the tempered glass fragments to the end of the tempering furnace 1, so as to quickly clean the broken glass inside the tempering furnace without affecting the subsequent processing of the tempered glass.

[0025] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
