DETAILED DESCRIPTION

[0026] In order to better understand and implement, the technical solutions in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model.

[0027] In the description of the utility model, it should be pointed out that the orientations or position relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like are the orientations or position relationships shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and are not intended to indicate or imply that the devices or elements indicated thereby must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the utility model belongs. The terms used in the specification of the utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the utility model.

[0029] Referring to Figure 1 and Figure 2 The utility model discloses a cooling air grid of synchronous positioning, including conveying mechanism, air grid group 20 and positioning mechanism, conveying mechanism includes conveying support 12 and a plurality of conveying roller way 11, a plurality of conveying roller way 11 can be rotatablely installed on conveying support 12, and the rotation of conveying roller way 11 can be driven by motor, or is realized rotation with motor cooperation transmission structure such as belt or chain, and a plurality of conveying roller way 11 are spaced apart along a conveying direction, and a plurality of conveying roller way 11 are formed into workpiece conveying surface together. The above-mentioned air grid group 20 can be arranged above the workpiece conveying surface, or the air grid group 20 is arranged below the workpiece conveying surface, or the air grid group 20 is arranged above and below the workpiece conveying surface.

[0030] The positioning mechanism includes first positioning piece 31 and second positioning piece, and the first positioning piece 31 is arranged on the conveying support 12, and the second positioning piece is arranged on the air grid group 20, the second positioning piece is connected with the first positioning piece 31 to prevent the air grid group 20 and the conveying support 12 from deviating relatively in the conveying direction.

[0031] On the basis of the above structure, when the cooling air grid of synchronous positioning of the utility model is used, a plurality of conveying roller ways 11 are rotatablely installed on the conveying support 12 of the conveying mechanism during the cooling air grid group 20, the plurality of conveying roller ways 11 can convey the glass into the cooling section during the rotation, the air grid group 20 can blow and cool the glass on the workpiece conveying surface above and / or below the workpiece conveying surface, and after the cooling action is completed, the glass is conveyed to the next station by the plurality of conveying roller ways 11.

[0032] Since the glass is high-temperature glass heated in the heating furnace and then conveyed to the plurality of conveying tracks, the air grid group 20, the conveying roller way 11 and the conveying support 12 and other components in the cooling section receiving the high-temperature glass will also be affected by the high temperature of the high-temperature glass and deformed.

[0033] For example, the conveying support 12 and the air grid group 20 will expand in the high-temperature condition, so that the conveying support 12 and the air grid group 20 will be stretched to a certain degree in the conveying direction, and for another example, cold shrinkage will also occur after the cooling action is completed or during the cooling process, so that the conveying support 12 and the air grid group 20 and other components will be retracted to a certain degree in the conveying direction, if the air grid group 20 and the conveying support 12 are separately arranged, the deformation of the air grid group 20 and the conveying support 12 is separate, so that there is a large difference in deformation amount.

[0034] Therefore, in the present application, the air grid group 20 is connected with the first positioning member 31 of the conveying support 12 through the second positioning member, and the first positioning member 31 and the second positioning member can prevent the air grid group 20 and the conveying support 12 from deviating from each other in the conveying direction. That is, when the conveying support 12 deforms in the conveying direction, the first positioning member 31 on the conveying support 12 will deviate from the original position in the conveying direction, so as to pull the second positioning member connected thereto to deviate together. Thus, the deformed deviation position of the air grid group 20 in the high-temperature state can be kept consistent with the conveying support 12. Therefore, the relative position of the air grid group 20 and the conveying roller 11 connected to the conveying support 12 in the conveying direction does not deviate too much from the initial state, so that the blowing position of the air grid group 20 deviates less from the conveying roller 11, and the situation of uneven cooling caused by the air grid group 20 deviating too much from the conveying roller 11 is reduced.

[0035] Further, the second positioning member includes a first positioning seat 32 and a second positioning seat 33, and the first positioning seat 32 and the second positioning seat 33 are arranged on the air grid group 20. Specifically, the first positioning seat 32 and the second positioning seat 33 can have two arrangement positions, one of which is arranged on the two sides of the air grid group 20 in the axial direction of the conveying roller, and the other of which is arranged on the front and rear of the air grid group 20 in the conveying direction.

[0036] If the first positioning seat and the second positioning seat are in the front and rear direction of the air grid group 20 in the conveying direction, that is, spaced apart in the conveying direction, the first positioning seat 32 and the second positioning seat 33 are arranged at the front end and the rear end of the air grid group 20. Corresponding to the at least two first positioning members 31 arranged on the conveying support 12 in the conveying direction, the same air grid group 20 can be connected and limited by the two first positioning members 31 adjacent in the conveying direction. The first positioning seat 32 is connected with one of the first positioning members 31 and slides up and down along the first positioning member 31, and the second positioning seat 33 is connected with the other first positioning member 31 and slides up and down along the first positioning member 31, and simultaneously slides in the axial direction of the conveying roller 11.

[0037] When the air grid group 20 is connected and positioned, the first positioning seat 32 at the front end of the air grid group 20 in the conveying direction is connected with the corresponding first positioning member 31, and the second positioning seat 33 of the air grid group 20 in the conveying direction is connected with the corresponding first positioning seat 32. Thus, the deformation of the front and rear ends of the same air grid group 20 can be positioned by the first positioning member 31. After the connection and positioning, the connection points of the air grid group 20 and the conveying support 12 in the conveying direction have two, so that the blowing position of the air grid group 20 is deformed synchronously with the conveying roller 11 connected to the conveying support 12 in the conveying direction. Therefore, the deviation position of the air grid group 20 relative to the conveying roller 11 is smaller, and the situation of uneven cooling caused by the air grid group 20 deviating too much from the conveying roller 11 is reduced.

[0038] Of course, since the wind grid group 20 needs to be adjusted in height relative to the glass during use according to the cooling temperature of the glass, the wind grid group 20 generally needs to be adjusted in height to adjust the blowing distance. Since the first positioning member 31 and the second positioning member are positioned and connected, the first positioning member 31 and the first positioning seat 32 can slide in the height direction, and the second positioning member and the second positioning seat 33 can also slide in the height direction, which can guide the height position adjustment of the wind grid group 20. Thus, only the sliding in the height direction is allowed, and the sliding in the conveying direction is limited, that is, the height adjustment of the wind grid group 20 does not affect the positions of the two in the conveying direction.

[0039] In addition, the first positioning member 31 and the second positioning seat 33 have a sliding trend along the conveying roller 11, so that when the conveying direction is the front-back direction of the wind grid group 20, the wind grid group 20 and the conveying support 12 can have a certain deflection in the left-right direction of the wind grid group 20. However, the deflection action is along the axis of the conveying roller 11, so that the left-right deflection of the wind grid group 20 does not deviate from the axis position of the conveying roller 11.

[0040] Of course, the first positioning seat 32 and the second positioning seat 33 are respectively arranged on the left and right sides of the wind grid group 20, so that the first positioning seat 32 and the second positioning seat 33 are positioned and connected in the left-right direction. Thus, the wind grid group 20 and the conveying support 12 are better synchronized in the axis direction of the conveying track, so that the blowing position of the wind grid group 20 is synchronized in deformation relative to the conveying roller 11 connected to the conveying support 12, and the relative position deviation is smaller.

[0041] In addition, the first positioning seat 32 and the second positioning seat 33 can be arranged in the front-back direction on one side of the wind grid group 20, and the second positioning seat 33 and the first positioning seat 32 can be arranged in the front-back direction on the other side of the wind grid group 20. Two first positioning members 31 are arranged on both sides of the conveying support 12. Thus, the wind grid group 20 and the conveying support 12 can be positioned by four positioning connection points, and the positioning structure of the wind grid group 20 and the conveying support 12 is uniformly distributed, and the deformation synchronization is better. Thus, the deviation position of the wind grid group 20 and the conveying roller 11 is smaller in deformation.

[0042] Specifically, the first positioning seat 32 is provided with a positioning through hole, and the second positioning seat 33 is provided with a sliding hole; the sliding hole extends along the conveying direction; one of the first positioning members 31 is inserted into the positioning through hole and slides along the axial direction of the positioning through hole; the other first positioning member 31 is inserted into the sliding hole 331 and slides along the axial direction of the conveying roller 11. In this way, when the first positioning member 31 cooperates with the second positioning member, one of the first positioning members 31 can be slidably inserted into the sliding hole, and the other first positioning member 31 can be slidably inserted into the positioning through hole, so that both of the first positioning members 31 can be guided to slide in the height direction relative to the first positioning seat 32 and the second positioning seat 33 of the second positioning member, and at the same time, the deviation in the conveying direction can be limited.

[0043] Of course, the second positioning member can also be provided with a positioning seat structure, which can limit the deviation of the air grid group 20 on the conveying support 12 by cooperating with the first positioning member 31. For example, the first positioning member 31 is a sliding sleeve, and the corresponding second positioning member is a sliding block or a sliding rod.

[0044] Further, the first positioning member 31 in the embodiment is a positioning column, which can be a positioning pin structure connected to the conveying support 12 or a threaded column structure. In any case, the first positioning member 31 can be inserted into the corresponding hole to achieve sliding cooperation.

[0045] Specifically, a gap is formed between the above-mentioned two adjacent conveying rollers 11, and the air grid group 20 is arranged at the middle position of the gap after being connected to the first positioning member 31 of the conveying support 12 by the second positioning member. That is to say, one air grid group 20 can be arranged at the gap position between each adjacent two conveying rollers 11, so that the upper and lower air grid groups 20 can conveniently blow air to the upper and lower surfaces of the glass during conveying, and the cooling effect is more uniform.

[0046] The air grid group 20 directly blows air to the position of the conveying roller 11, and the conveying roller 11 blocks part of the airflow, so that the cooling speed of each part of the glass surface is inconsistent, which causes uneven stress and deformation of the glass, and affects the quality and performance of the glass, such as flatness and optical performance. Therefore, after the first positioning member 31 and the second positioning member are connected, the blowing position of the air grid group 20 corresponds to the middle position of the two conveying rollers 11, so that the airflow is effectively reduced by the conveying roller 11, and the cooling air uniformly covers the surface of the glass, so that each part of the glass is uniformly cooled.

[0047] Further, the air grid group 20 in the embodiment includes an air box and air nozzles 21 arranged in communication with the air box and used for guiding the airflow in the air box to blow towards the workpiece conveying surface; a second positioning member is connected to the air box, and the second positioning member is connected with the first positioning member 31 to make the plurality of air nozzles 21 correspond to the spaced intermediate positions. In this way, when the air box is installed, after the second positioning member of the air box is positioned and connected with the first positioning member 31 of the conveying support 12, the air nozzles 21 can be positioned at the intermediate positions of the conveying intervals.

[0048] Of course, it should be noted that in the case of one-sided arrangement of the first positioning member 31 and the second positioning member, taking the shaft ends of the adjacent two conveying roller tracks 11 and the conveying support 12 forming two connection points as an example, the first positioning member 31 for installing the same air grid group 20 is arranged at the intermediate position of the two connection points, and correspondingly, the second positioning member on the air box is arranged at the intermediate position in the front-rear direction of the air box; and the air nozzles 21 correspond to the intermediate position of the air box.

[0049] In the case of two-sided arrangement of the first positioning member 31 and the second positioning member, the two first positioning members 31 on one side of the conveying support 12 for installing the same air grid group 20 can correspond to the connection points of the adjacent two conveying roller tracks 11 and the conveying support 12, respectively, and the second positioning member formed by the first positioning seat 32 and the second positioning seat 33 of the air box can be arranged correspondingly to the two first positioning members 31, so that the air nozzles 21 are arranged at the intermediate position of the air box.

[0050] The arrangement positions of the first positioning member 31 and the second positioning member are selected according to actual needs, so that the blowing position of the air grid group 20 corresponds to the interval between the two conveying roller tracks 11 after assembly.

[0051] Further, the upper and lower sides of the workpiece conveying surface are provided with a plurality of air grid groups 20, so that different positions are provided with air grid groups 20 for upward and downward blowing and cooling during the glass cooling process, and the glass cooling effect is better.

[0052] Further, the synchronous positioning cooling air grid further includes a hanging member 40, one end of the hanging member 40 is slidably connected to the air grid group 20 located above the workpiece conveying surface, and the other end of the hanging member 40 is slidably connected to the air grid group 20 located below the workpiece conveying surface, so that the air grid group 20 can be hung on the air grid support or rack through the hanging member 40, and the air grid group 20 can be vertically positioned under the action of its own gravity.

[0053] Further, the hanging member 40 is a flexible member, which can be a boom hinged on the air grid support or rack through a ball head structure, so as to flexibly swing with deformation, or be a steel wire rope structure for hoisting, in any case, the air grid group 20 can be positioned in the vertical direction.

[0054] Embodiment 2,

[0055] A glass production equipment comprises the synchronously positioned cooling air grid of embodiment 1, and in particular, a conveying mechanism that conveys the glass to the cooling air grid after the glass is heated by a heating furnace of the glass production equipment, and a plurality of conveying rollers of the conveying mechanism receive the heated glass and cooperate with the air grid group 20 to guide the cold air to blow against the surface of the glass to cool the glass.

[0056] The air grid group 20 is connected to the first positioning member 31 of the conveying support 12 through the second positioning member, and the first positioning member 31 and the second positioning member can place the air grid group 20 and the conveying support 12 in relative deviation in the conveying direction, that is, when the conveying support 12 deforms in the conveying direction, the first positioning member 31 on the conveying support 12 deviates from the original position in the conveying direction, so as to pull the second positioning member connected thereto to deviate together, so that the air grid group 20 connected to the second positioning member can also be in a deformed deviation position under the high-temperature state, and the conveying support 12 can be kept relatively consistent, so that the relative position of the air grid group 20 and the conveying support 12 in the conveying direction does not deviate too much from the initial state, and thus the blowing position of the air grid group 20 deviates less from the conveying roller way 11 connected to the conveying support 12, reducing the situation that the air grid group 20 deviates too much from the conveying roller way 11 and causes uneven cooling, thereby improving the glass production quality.

[0057] It should be noted that the other structures and effects of the synchronously positioned cooling air grid of the embodiment are the same as those of embodiment 1, and will not be described in detail here.
