Description

Technical Field

[0001] The utility model relates to the technical field of tempered glass processing, in particular to a multi-head blowing device for cooling tempered glass. Background Art

[0002] Tempered glass is a type of safety glass. In fact, tempered glass is a prestressed glass. In order to increase the strength of the glass, chemical or physical methods are usually used to form compressive stress on the surface of the glass. When the glass is subjected to external force, the surface stress is first offset, thereby increasing the bearing capacity and enhancing the glass's own resistance to wind pressure, cold and heat, impact, etc. Please note to distinguish it from fiberglass.

[0003] The Chinese utility model patent with the authorization announcement number "CN220224003U" specifically states that "the cooling device for processing tempered glass, through the cooling mechanism, the wind blows on the ice and quickly turns into cold wind, and the two rows of cold wind blow on the tempered glass, thereby achieving the purpose of rapid cooling of the tempered glass and improving the efficiency of cooling the tempered glass. The cooling device for processing tempered glass, through the conveying mechanism, places the tempered glass inside the support frame, at which time the two sides of the tempered glass are respectively in contact with the first conveying roller, and the bottom of the tempered glass is in contact with the second conveying roller, which can achieve the purpose of conveying the tempered glass";

[0004] The above device reduces the problem of the fan blowing onto the surface of the tempered glass by adding ice cubes to improve the cooling efficiency. However, ice cubes are easy to melt. Therefore, in order to ensure long-term efficient cooling, ice cubes need to be added frequently. In addition, the number of ice cubes is large, and each addition is very inconvenient. More importantly, the cooling exhaust ducts designed for the above device are all located on the upper surface of the tempered glass, and can only cool one side of the tempered glass, resulting in an incomplete cooling effect. At the same time, due to the various shapes of tempered glass, it is difficult for the curved tempered glass to be cooled evenly and efficiently when passing through the exhaust duct designed for the above device, resulting in an incomplete cooling effect. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the utility model provides a multi-head blowing device for cooling tempered glass, which can effectively solve the problems raised in the background technology.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] The utility model provides a multi-head blowing device for cooling tempered glass, comprising a machine base and a plurality of conveying rollers rotatably mounted on two opposite inner side walls of the machine base, a blowing air box is lifted and slidably mounted above the machine base, a plurality of blowing air pipes are lifted and slidably mounted at the bottom of the blowing air box, extrusion cross bars that are simultaneously in contact with the outer tube walls of the plurality of blowing air pipes are telescopically and slidably mounted in the blowing air box, the blowing assembly comprises a fan arranged above the blowing air box, a refrigerator is mounted on the input end of the fan, one of the output ends of the fan is connected to the plurality of blowing air pipes through the blowing air box, and the other output end is connected to a bottom exhaust tube that is located below the plurality of conveying rollers and embedded in the bottom of the inner cavity of the machine base.

[0008] Furthermore, the ends of several conveying rollers extending into the machine base are equipped with sprockets that are mutually transmission-connected, the outer wall of the machine base is equipped with a motor whose output end is connected to one of the sprockets, and the bottom of the machine base is equipped with two symmetrically distributed frames.

[0009] Furthermore, a top seat is fixedly installed on the top of the machine base, and a lifting cylinder is fixedly installed on the top of the top seat. The output end of the lifting cylinder extends through and extends to the bottom of the machine base and is connected to the top of the blowing air box.

[0010] Furthermore, the fan is installed on the top of the top seat, and the output end of the fan extends through to the bottom of the seat, and is connected to the blower air box through an air inlet pipe.

[0011] Furthermore, the bottom of the inner cavity of the air box is provided with square holes penetrating through the bottom to facilitate the lifting and sliding of the corresponding air pipe, a rubber ball is installed at the bottom of the air pipe, an exhaust hole connected to the output end of the bottom of the air pipe is penetrated on the rubber ball, and an anti-slip ring is installed at the top of the air pipe extending into the air box.

[0012] Furthermore, a telescopic cylinder is installed on the outer side wall of the blowing air box, and the output end of the telescopic cylinder is connected to a telescopic rod extending into the inner cavity of the blowing air box and fixedly connected to the extrusion cross bar.

[0013] Compared with the known prior art, the technical solution provided by the utility model has the following beneficial effects:

[0014] 1. A number of blowing air pipes with adjustable lengths are arranged above the walking path of the tempered glass. When the curved tempered glass is transported to the bottom of the blowing air pipes, the blowing air pipes fall freely due to gravity, and automatically adjust to different degrees of expansion and contraction according to the curved surface of the tempered glass, ensuring that the distance between each blowing air pipe and the surface of the tempered glass is consistent, and the positions of the blowing air pipes are fixed by squeezing and limiting. After the fan is started, cold air is blown into the blowing air pipes to cool the surface of the tempered glass in an all-round and uniform manner;

[0015] 2. Install a cooler at the input end of the fan. The cooler cools the air generated at the air inlet end of the fan, eliminating the need to repeatedly add ice cubes, which is convenient to operate. At the same time, the fan not only supplies air to several air-blowing pipes but also supplies air to the exhaust pipe located under the tempered glass, enabling the upper and lower sides of the tempered glass to be cooled simultaneously by low-temperature air cooling, featuring a comprehensive cooling effect.

This refrigerator uses a conductor to connect two different metals. When direct current is turned on, the temperature at one connection point decreases and the temperature at the other connection point increases. One of the output ends of the fan 22 is connected to a plurality of blowing air pipes 41 through a blowing air box 3, and the other output end is connected to a bottom exhaust duct 14 located below a plurality of conveying rollers 11 and embedded in the bottom of the inner cavity of the base 1. The tempered glass moves on the plurality of conveying rollers 11, so there is no cooling dead corner.

[0026] Example 2

[0027] Reference Figures 1-4 , which is the second embodiment of the utility model, which is different from the first embodiment in that: one end of a plurality of conveying rollers 11 extending into the base 1 is equipped with sprockets that are mutually transmission-connected, that is, a chain is set between the sprockets at the ends of two adjacent conveying rollers 11, and the outer wall of the base 1 is equipped with a motor 12 whose output end is connected to one of the sprockets, and the bottom of the base 1 is equipped with two symmetrically distributed frames 13, the top of the base 1 is fixedly installed with a top seat 2, and the top of the top seat 2 is fixedly installed with a lifting cylinder 21, the output end of the lifting cylinder 21 extends through the bottom of the base 1 and is connected to the top of the blowing air box 3, the fan 22 is installed on the top of the top seat 2, and the output end of the fan 22 extends through the bottom of the base 1, and is connected to the top of the blowing air box 3 with an air inlet pipe 23, and the blowing air box 3 The bottom of the inner cavity is penetrated through the lower bottom and is provided with square holes 31 for facilitating the lifting and sliding of the blowing air pipe 41. The bottom of the blowing air pipe 41 is installed with a rubber ball 42. The rubber ball 42 can prevent the tempered glass surface from being damaged by impact during the descent of the blowing air pipe 41. The rubber ball 42 is penetrated with an exhaust hole connected to the output end of the bottom of the blowing air pipe 41 to ensure that the air-cooling air path is unobstructed. The top of the blowing air pipe 41 extending into the blowing air box 3 is installed with an anti-slip ring 43. The specification of the anti-slip ring 43 is larger than the caliber of the square hole 31, so that the blowing air pipe 41 will not fall out of the square hole 31. The outer wall of the blowing air box 3 is installed with a telescopic cylinder 51. The output end of the telescopic cylinder 51 is connected to a telescopic rod 53 that extends into the inner cavity of the blowing air box 3 and is fixedly connected to the extrusion cross bar 52.

[0028] The remaining structures are the same as those of Example 1.

[0029] The working process of the present utility model is as follows:

[0030] First, start the lifting cylinder 21 to drive the blowing air box 3 including a number of blowing air pipes 41 to rise as a whole, and place the tempered glass to be cooled on the conveying roller 11. Then start the motor 12 to drive the corresponding sprocket to rotate. Through the meshing transmission between a number of sprockets, the synchronous rotation of a number of conveying rollers 11 is realized, and the tempered glass is conveyed at a uniform speed;

[0031] Secondly, when one end of the tempered glass moves directly above a number of blowing air pipes 41, start the lifting cylinder 21 to drive the blowing air box 3 including a number of blowing air pipes 41 to descend as a whole until the rubber balls 42 at the bottom of all blowing air pipes 41 are in contact with the upper surface of the tempered glass. For the tempered glass with an arc surface, at this time, the lengths of a number of blowing air pipes 41 extending into the blowing air box 3 are not exactly the same, but it is always ensured that the rubber balls 42 are in contact with the upper surface of the tempered glass. At this time, start the telescopic cylinder 51, and push the extrusion cross bar 52 through the telescopic rod 53 to extrude and resist a number of blowing air pipes 41, so that a number of blowing air pipes 41 and the rubber balls 42 at their bottoms are fixed. Finally, start the lifting cylinder 21 again to drive the blowing air box 3 including a number of blowing air pipes 41 to rise slightly as a whole, so that the bottom of the rubber ball 42 is no longer in contact with the arc-shaped tempered glass, ensuring that the exhaust holes opened on the rubber ball 42 are not blocked;

[0032] Finally, along with the uniform conveyance of the tempered glass, start the fan 22 and the cooler installed at the input end of the fan 22. Cool the air introduced into the air inlet end of the fan 22 through the cooler. After being extracted by the fan 22, it is sent into the blowing air box 3 through the air inlet pipe 23 and discharged through a number of blowing air pipes 41 and the exhaust holes on the rubber balls 42 at the bottom, so as to uniformly and efficiently cool the upper surface of the arc-shaped tempered glass by air cooling. At the same time, another output end of the fan 22 is connected to the bottom exhaust duct 14, and the bottom of the tempered glass being conveyed at a uniform speed is cooled by air cooling through the bottom exhaust duct 14, ensuring that the upper and lower surfaces of the tempered glass are cooled by air cooling at the same time, improving the cooling efficiency and making the cooling effect more uniform.

[0033] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present utility model.
