Description

Technical Field

[0001] The utility model belongs to the technical field of protective layer spraying, and in particular relates to a protective layer spraying device for the surface of float glass. Background Art

[0002] Float glass is a process for manufacturing float glass with a protective layer spraying device. It refers to glass made using the floating method. The general principle is to pour the molten glass liquid on the surface of a liquid (liquid tin) with a specific gravity greater than the glass liquid to form the glass. Compared with other mechanical methods, its advantage is that it can reduce the occurrence of uneven glass or bubbles caused by mechanical vibration, and because as long as the glass liquid is continuously added to the liquid surface, it is theoretically possible to make infinitely long glass;

[0003] Spraying a protective layer on the surface of float glass can make it have better performance, but in the prior art, usually only one side of the float glass can be sprayed at a time. If both sides of the float glass are to be sprayed, the float glass needs to be turned over. During the turning process, the float glass is easily damaged. Utility Model Content

[0027] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0028] like Figure 1-3 As shown, a float glass surface protective layer spraying device comprises a workbench 1, two mounting plates 2 are symmetrically fixedly connected to the upper side of the workbench 1, a plurality of conveying shafts 21 are rotatably connected between the two mounting plates 2, the plurality of conveying shafts 21 are transmission-connected to each other, the plurality of conveying shafts 21 are all fixedly connected to a plurality of supporting rings 22, the supporting rings 22 fixedly connected to the mounting plate 2 on the left side and the supporting rings 22 fixedly connected to the mounting plate 2 on the right side are alternately arranged, the plurality of supporting rings 22 are evenly arranged, a plurality of first nozzles 31 are arranged above the conveying shafts 21, a plurality of second nozzles 32 are arranged below the conveying shafts 21, the first nozzles 31 and the second nozzles 32 are assembled and connected to a gas delivery component 3.

[0029] With the technical solution of this embodiment, it should be noted that the float glass is transferred into the device through a conveying device, the support ring 22 is made of rubber material, the conveying shaft 21 drives the support ring 22 to rotate, and the support ring 22 conveys the float glass when it rotates. The float glass is input from the left side and output from the right side. When the float glass moves from the left side to the right side, the contact positions of the support ring 22 on the left side and the support ring 22 on the right side with the float glass are different. During the movement of the float glass, the first nozzle 31 and the second nozzle 32 spray the float glass.

[0030] Reference Figure 3 : Support columns 11 fixedly connected to the workbench 1 are fixedly connected at both ends of the two mounting plates 2.

[0031] In this embodiment, the support column 11 is used to isolate the workbench 1 from the mounting plate 2.

[0032] Reference Figure 2A conveyor belt 41 is connected between the conveying shafts 21, and a motor 42 is assembled and connected in the middle of a mounting plate 2, and the output shaft of the motor 42 is connected to the conveyor belt 41.

[0033] In this embodiment, the motor 42 is used to drive the conveyor belt 41 to work, and the conveyor belt 41 drives the conveyor shaft 21 to rotate.

[0034] Reference Figure 2 : The gas delivery component 3 includes a first gas delivery pipe 301, a second gas delivery pipe 302 and a third gas delivery pipe 303. The first gas delivery pipe 301, the second gas delivery pipe 302 and the third gas delivery pipe 303 are connected by a connecting pipe 304. The connecting pipe 304 is connected to the gas. The first gas delivery pipe 301 and the second gas delivery pipe 302 are located below the delivery shaft 21. Multiple second nozzles 32 are connected to the first gas delivery pipe 301 and the second gas delivery pipe 302. Multiple first nozzles 31 are connected to the third gas delivery pipe 303.

[0035] In this embodiment, the connecting pipe 304 is used to connect the first gas pipe 301, the second gas pipe 302 and the third gas pipe 303. The first nozzle 31 sprays the upper surface of the float glass, and the second nozzle 32 sprays the lower side of the float glass. The first gas pipe 301 and the second gas pipe 302 transport gas to the second nozzle 32, and the third gas pipe 303 sprays the first nozzle 31.

[0036] Reference Figure 2 : The number of conveying shafts 21 arranged on the input side and the output side of the workbench 1 is three, the first air pipe 301 is located on the input side of the workbench 1, the second air pipe 302 is located between the two conveying shafts 21 in the middle, the second nozzles 32 assembled and connected to the first air pipe 301 and the second air pipe 302 are arranged alternately, and the second nozzle 32 is located between two adjacent support rings 22.

[0037] In the present embodiment, when the float glass enters above the conveying shaft 21, the first gas pipe 301 conveys gas to the second nozzle 32, and the second nozzle 32 sprays the portion of the lower side of the float glass located between the support rings 22. When the float glass is conveyed to the upper position of the second gas pipe 302, the second nozzle 32 sprays the portion of the lower side of the float glass located between the support rings 22. Since the position of the support rings 22 on the input side is staggered with the position of the support rings 22 below the second gas pipe 302, the second nozzle 32 connected to the second gas pipe 302 sprays the unsprayed portion of the lower side of the float glass, and the sprayed portion contacts the support ring 22. The sprayed portion of the float glass contacts the support ring 22 on the right side after a period of time, so the support ring 22 will not affect the sprayed portion of the float glass.

[0038] Reference Figure 2: A stopper 5 is provided between two adjacent second nozzles 32 .

[0039] In this embodiment, the width of the block 5 is the same as the width of the support ring 22 and is located on the same line as the support ring 22, so the contact portion of the float glass with the support ring 22 will not come into contact with the gas. The block 5 is used to isolate the gas sprayed from the second nozzle 32 to prevent the gas from being sprayed to the middle position between two adjacent second nozzles 32.

[0040] Reference Figure 1 : An isolation cover 6 is fixedly connected to the upper side of the workbench 1.

[0041] In this embodiment, the isolation cover 6 is used to isolate the gas inside the isolation cover to prevent sulfur dioxide gas from polluting the environment.

[0042] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0043] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
