Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] The glass production device can be used to form patterned glass, specifically, the patterned glass is formed by rolling with a roller. However, after the glass production device has been running for a long time, oxides such as sulfate will adhere to the roller, which may easily lead to shallow pattern depth or incomplete pattern on the formed glass. Therefore, the roller needs to be cleaned regularly and frequently to ensure the processing quality of the glass pattern, but this cleaning operation will affect the processing efficiency of the glass.

[0034] In view of this, the first embodiment of the utility model proposes an anti-glare patterned glass production device 10, which can ensure the processing quality of the pattern of the glass 20 and improve the processing efficiency of the glass 20. It should be noted that the anti-glare patterned glass production device 10 can be used to process glass 20 with anti-glare patterns, and can also be used to process glass 20 with other patterns. Some embodiments of the present application are described by taking the processing of glass 20 with anti-glare patterns as an example. Figures 1 to 4 The anti-glare patterned glass production device 10 according to an embodiment of the present application is introduced. Specifically, the anti-glare patterned glass production device 10 includes a roller group 100 and an air outlet assembly 200 .

[0035] Reference Figure 1 and Figure 2The roller group 100 is used for rolling the glass 20. The roller group 100 includes a first roller body 110 and a second roller body 120 arranged at intervals. The structure of the first roller body 110 can be the same as that of the second roller body 120, or it can be different. Some embodiments of the present application are described by taking the first roller body 110 and the second roller body 120 having the same structure as an example. The specific arrangement of the first roller body 110 and the second roller body 120 is described below. The axis of the first roller body 110 is parallel to the axis of the second roller body 120. Figure 1 As a reference, the first roller body 110 and the second roller body 120 are both arranged to extend in the front-to-back direction. The first roller body 110 and the second roller body 120 form a gap 130, and the specific size of the gap 130 can be determined according to actual conditions. It can be understood that the gap 130 is suitable for the glass 20 to pass through so as to roll the glass 20. The specific arrangement of the roller group 100 can refer to the relevant known technology.

[0036] Reference Figure 1 and Figure 2 , the specific configuration of the air outlet assembly 200 is described below. The air outlet assembly 200 includes a first air outlet 210. The first air outlet 210 faces the roller assembly 100, that is, it can guide the airflow to the roller assembly 100. Specifically, the first air outlet 210 can guide the airflow to the peripheral wall of the roller assembly 100. In addition, in some embodiments, the air outlet assembly 200 can be arranged on the side of the roller assembly 100 for the glass 20 to enter the roller assembly 100, so as to Figure 2 The orientation in FIG. 1 is used as a reference, that is, the air outlet assembly 200 can be arranged on the left side of the roller assembly 100. In other embodiments, the air outlet assembly 200 can be arranged on the side of the roller assembly 100 for the glass 20 to be rolled out. Figure 2 The orientation in is used as a reference, that is, the air outlet assembly 200 can also be arranged on the right side of the roller assembly 100. Some embodiments of the present application are described by taking the air outlet assembly 200 being arranged on the side of the roller assembly 100 for the glass 20 to be rolled out as an example.

[0037] It should be noted that in some embodiments, the air outlet assembly 200 may be connected to the roller assembly 100. In other embodiments, the air outlet assembly 200 may also be arranged separately from the roller assembly 100, that is, the air outlet assembly 200 can be conveniently adjusted to the blowing position according to actual needs.

[0038] In the technical solution of the utility model, the anti-glare patterned glass production device 10 includes a roller group 100 and an air outlet assembly 200. The roller group 100 includes a first roller body 110 and a second roller body 120 arranged at intervals. The axis of the first roller body 110 is parallel to the axis of the second roller body 120, and the first roller body 110 and the second roller body 120 can form a gap 130, and the gap 130 can allow the glass 20 to pass through to roll the glass 20. In the prior art, it is necessary to regularly and frequently clean the oxides on the roller body to ensure the rolling quality of the glass pattern, but this cleaning operation will affect the processing efficiency of the glass 20. In this solution, the first air outlet 210 of the air outlet assembly 200 faces the roller group 100, that is, it can guide the airflow to the roller group 100. Therefore, this solution can effectively slow down the accumulation of oxides on the roller group 100, that is, reduce the frequency of cleaning the roller group 100. This solution can not only ensure the processing quality of the glass 20 pattern, but also improve the processing efficiency of the glass 20. Furthermore, in the present solution, the airflow directed toward the roller group 100 by the first air outlet 210 can also blow toward the glass 20 along the surface of the roller group 100. Therefore, the airflow can also cool the glass 20 after exiting the rollers, that is, it can achieve the shaping of the pattern of the glass 20, weaken the effect of deviation or fluctuation of the pattern of the glass 20, and further improve the molding quality of the pattern of the glass 20.

[0039] The specific configuration of the first air outlet 210 is described below. Figure 1 In some embodiments, the first air outlet 210 can be directed toward the first roller body 110 to direct the airflow toward the first roller body 110 , which can effectively slow down the accumulation of oxides on the first roller body 110 and reduce the cleaning frequency of the first roller body 110 .

[0040] In other embodiments, not shown in the drawings, the first air outlet 210 may be directed toward the second roller 120, thereby directing the airflow toward the second roller 120, which can effectively reduce the accumulation of oxides on the second roller 120 and reduce the cleaning frequency of the second roller 120. In other embodiments, the first air outlet 210 may be directed toward both the first roller 110 and the second roller 120, which can simultaneously reduce the accumulation of oxides on both the first roller 110 and the second roller 120.

[0041] Reference Figure 2 In some embodiments, the air outlet assembly 200 includes a second air outlet 220. The structure of the second air outlet 220 may be the same as that of the first air outlet 210, or may be different from that of the first air outlet 210. In some embodiments of the present application, the structure of the second air outlet 220 is the same as that of the first air outlet 210.

[0042] The second air outlet 220 is specifically configured as follows. The second air outlet 220 faces the glass 20, that is, it can direct the airflow toward the glass 20, thereby achieving rapid cooling of the glass 20, effectively suppressing deformation of the pattern of the glass 20, allowing the pattern of the glass 20 to be quickly fixed, and improving the quality of the pattern of the glass 20.

[0043] Reference Figure 1 and Figure 2 In some embodiments, the air outlet assembly 200 includes an air outlet pipe 240. The air outlet pipe 240 can be connected to the air supply device, that is, the airflow generated by the air supply device can be introduced into the air outlet pipe 240, and then guided to the roller group 100 from the air outlet on the air outlet pipe 240, so as to delay the accumulation of oxides on the roller group 100 and realize the cooling of the glass 20.

[0044] Reference Figure 1 The air outlet pipe 240 is provided with a plurality of first air outlets 210. Specifically, the first air outlets 210 can be set to two, three or four, etc. The specific number of the first air outlets 210 can be determined according to actual conditions. The specific settings of the first air outlets 210 can be the same or different.

[0045] The specific arrangement of the first air outlets 210 on the air outlet duct 240 is introduced below. The first air outlets 210 are arranged at intervals along the direction of the axis of the air outlet duct 240. In some embodiments, the interval between each adjacent two first air outlets 210 on the air outlet duct 240 can be uniformly spaced. In other embodiments, the interval between each adjacent two first air outlets 210 on the air outlet duct 240 can also be non-uniformly spaced. Some embodiments of the present application are described by taking the non-uniform arrangement of multiple first air outlets 210 as an example. Specifically, the roller group 100 has a middle portion along its extension direction, so that the multiple first air outlets 210 near the middle portion of the air outlet duct 240 can be densely arranged. Affected by the traction force of the glass 20 during the forming process, the temperature of the position of the glass 20 close to the middle portion of the roller group 100 is higher, and the temperature of the side of the glass 20 away from the middle portion is lower. This solution arranges the multiple first air outlets 210 near the middle part of the air outlet duct 240 densely, which can achieve strong cooling of the middle glass 20, inhibit deformation of the pattern of the glass 20, and make the temperature of each part of the molded glass 20 uniform, thereby ensuring the quality of the glass 20.

[0046] In some embodiments, the air outlet assembly 200 includes an adjustment member, which is not shown in the drawings, and the adjustment member is connected to the air outlet pipe 240. The adjustment member is used to drive the air outlet pipe 240 to rotate around its axis, thereby adjusting the air outlet direction of the first air outlet 210. By setting the adjustment member, this solution can selectively blow air to cool down various positions of the roller group 100, thereby ensuring the molding quality of the glass 20.

[0047] Reference Figure 4 In some embodiments, the air outlet 240 has a cavity 241, and the air outlet 240 includes a plurality of vents 242 that are in communication with the cavity 241. Each first air outlet 210 is connected to each vent 242 in a one-to-one correspondence, that is, the airflow in the cavity 241 can be guided from the vent 242 to the first air outlet 210, and then guided from the first air outlet 210 to the roller group 100. Among them, the opening area of ​​the vent 242 in the air outlet 240 is smaller than the opening area of ​​the air outlet. In some embodiments, the vent 242 can be circular, square, polygonal, etc. It should be noted that the shape of the first air outlet 210 can be the same as or different from the vent 242. Some embodiments of the present application take the shape of the first air outlet 210 as the same as the vent 242, and both are square as an example for explanation. This scheme adopts the above-mentioned setting so that the airflow can be compressed at the vent 242, the air outlet speed at the first air outlet 210 is increased, and the air outlet area is increased, so as to ensure the cooling effect of the roller group 100.

[0048] Reference Figure 4 In some embodiments, the air outlet duct 240 includes a first side wall 243 arranged along the transverse direction X. Figure 4 The orientation in is used as a reference, and the horizontal direction X can point to the front-to-back direction. One end of the first side wall 243 is connected to the first air outlet 210, and the other end is connected to the vent 242, that is, the first side wall 243 is used to form the first air outlet 210 and the vent 242. Along the vent 242 to the first air outlet 210, the distance from the first side wall 243 to the axis of the air outlet gradually decreases. In other words, the first side wall 243 is arranged at an angle. The above-mentioned arrangement adopted in this scheme can ensure the acceleration effect of the outlet airflow and increase the air outlet area.

[0049] In other embodiments, the air outlet duct 240 includes a second side wall 244 opposite to the first side wall 243. Similarly, one end of the second side wall 244 is connected to the first air outlet 210, and the other end is connected to the vent 242, that is, the second side wall 244 and the first side wall 243 are both used to form the first air outlet 210 and the vent 242. The above arrangement of this solution can ensure the acceleration effect of the outlet airflow and further increase the outlet area.

[0050] Reference Figure 1 and Figure 3 In some embodiments, the first roller body 110 and the second roller body 120 are arranged opposite to each other along the vertical direction Z. Figure 1The first roller 110 and the second roller 120 are arranged opposite to each other along the vertical direction Z. The first roller 110 has a first portion 111 and a second portion 112 along the vertical direction Z. In order to facilitate the description and understanding of the specific division of the first portion 111 and the second portion 112, a central plane is defined. The first portion 111 and the second portion 112 are symmetrical about the central plane. In addition, the first portion 111 is located on the side of the second portion 112 that is away from the second roller 120. Figure 2 The direction in is used as a reference, wherein the dotted line indicates the center plane, that is, the first part 111 is located above the dotted line, and the second part 112 is located below the dotted line. Compared with the solution in which the first air outlet 210 faces the first part 111, the first air outlet 210 in this solution faces the second part 112, which can effectively shorten the distance that the airflow is guided to the glass 20, that is, the glass 20 exiting the roller can be cooled more quickly, the deformation of the pattern of the glass 20 can be suppressed, and the molding quality of the pattern of the glass 20 can be guaranteed.

[0051] Reference Figure 3 In some embodiments, the air outlet assembly 200 includes an air outlet pipe 240, and the air outlet pipe 240 is provided with a first air outlet 210 and a third air outlet 230. It can be understood that the first air outlet 210 and the third air outlet 230 are arranged at intervals. It should be noted that the first air outlet 210 and the third air outlet 230 can be arranged on the same air outlet pipe 240, or can be arranged on different air outlet pipes 240 respectively. Some embodiments of the present application are described by taking the first air outlet 210 and the third air outlet 230 being arranged on the same air outlet pipe 240 as an example. The positions of the first air outlet 210 and the third air outlet 230 are introduced below. For the convenience of description and understanding, it is defined that the first roller body 110 has a middle part along its axial direction, the first air outlet 210 is arranged near the middle part, and the third air outlet 230 is arranged away from the middle part.

[0052] Reference Figure 3 , the first air outlet 210 and the third air outlet 230 are both facing the first roller body 110. The structure of the first outlet can be the same as that of the third air outlet 230. Further, the distance from the first air outlet 210 to the first roller body 110 is less than the distance from the third air outlet 230 to the first roller body 110. It should be noted that in some embodiments, the air outlet pipe 240 can be set to an arc shape, so that the first air outlet 210 is closer to the first roller body 110 than the third air outlet 230, so as to achieve strong cooling of the middle part of the glass 20. In other embodiments, the first air outlet 210 and the third air outlet 230 can be set on different air outlet pipes 240, and the part of the air outlet pipes 240 are all linear, so that the first air outlet 210 is closer to the first roller body 110 than the third air outlet 230. Some embodiments of the present application are described by taking the air outlet pipe 240 as an example.

[0053] In some embodiments, reference Figure 1 and Figure 2 The anti-glare patterned glass production device 10 may also be provided with a transition roller 140. The transition roller 140 may drive the glass 20 to continuously move to the next process for processing.

[0054] The second embodiment of the utility model proposes a production line, which includes the anti-glare patterned glass production device 10 of the above embodiment. This solution can effectively slow down the accumulation of oxides on the roller group 100, that is, reduce the frequency of cleaning the roller group 100. This solution can not only ensure the processing quality of the pattern of the glass 20, but also improve the processing efficiency of the glass 20. Furthermore, in this solution, the airflow directed to the roller group 100 by the first air outlet 210 can also blow toward the glass 20 along the surface of the roller group 100. Therefore, the airflow can also cool the glass 20 after it leaves the roller, that is, it can achieve the shaping of the pattern of the glass 20, weaken the effect of deviation or fluctuation of the pattern of the glass 20, and further improve the molding quality of the pattern of the glass 20.
