Description

Technical Field

[0001] The utility model relates to the technical field of glass product manufacturing, in particular to an annealing device for improving the crystallinity of glass products. Background Art

[0002] Annealing is a heat treatment process used to reduce internal stress in a material and improve its mechanical properties. For glass products, the annealing process is particularly critical because it helps eliminate stress generated during the manufacturing process, thereby improving the uniformity and transparency of the glass.

[0003] The existing glass product annealing device uses a conveyor belt to transport the glass products to an annealing hood for annealing. Usually, the annealing temperature near the two sides of the conveyor belt is higher. During the conveying process, the glass products are placed on the conveyor belt, and the positions of the glass products and the conveyor belt are relatively fixed, resulting in uneven heating of the glass products during annealing. The uneven annealing causes different degrees of residual stress inside the glass, so that the glass has different refractive indices in different areas, thereby affecting the propagation of light and the crystallinity of the glass products. Utility Model Content

[0004] The utility model aims to provide an annealing device for improving the crystallinity of glass products, which effectively solves the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions.

[0006] An annealing device for improving the crystallinity of glass products comprises a workbench, two side guard plates are symmetrically fixed above the workbench, an annealing module is arranged on the workbench, a conveying mechanism is arranged between the two side guard plates, the conveying mechanism passes through the annealing module, the conveying mechanism is used to convey glass products, the annealing module is used to spray flames from both sides and downward to anneal the glass products, a plurality of mounting plates are arranged in an array along the conveying direction of the conveying mechanism, a mounting seat is installed on each mounting plate, a vertically extending shaft rod is rotatably installed on the top of each mounting seat, and a placement seat for placing glass products is fixed at the end of each shaft rod, and a linkage mechanism is provided on one side of the side guard plates, which is used to link the shaft rod to rotate when the conveying mechanism is running for conveying.

[0007] It can be seen that by setting a linkage mechanism on one side guard plate, during the transportation of the glass products by the conveying mechanism, the linkage effect of the linkage mechanism can be utilized to drive the shaft rod, the placement seat and the glass products to rotate, so that the glass products can rotate during the movement, thereby ensuring the uniformity of heat annealing of the glass products at all parts, effectively improving the crystal clearness of the glass products, and the self-rotation drive of the glass products comes from the linkage of the linkage mechanism, without the need to set up additional drive, thereby reducing the equipment cost investment.

[0008] Furthermore, the conveying mechanism includes a main guide roller, a driven guide roller, a driving motor and two conveying chains. The main guide roller and the driven guide roller are respectively rotatably installed on both sides between the two side guard plates. The driving motor is fixed on the outer surface of one of the side guard plates, and the output shaft is fixed to one end of the main guide roller. Two sprockets are fixedly mounted on the main guide roller and the driven guide roller. The corresponding two sprockets are jointly driven by a conveying chain, and a plurality of mounting plate arrays are fixed on the two conveying chains.

[0009] Furthermore, the linkage mechanism includes a bracket and a rack, wherein a plurality of brackets are fixed on the inner surface of a side guard plate, the rack is fixed on the end of the bracket, each shaft rod is fixedly sleeved with a gear meshing with the rack, each mounting plate is provided with a slide groove, each mounting seat is slidably installed in the corresponding slide groove, each slide groove is arranged with a spring, one end of the spring is fixed to the side surface of the mounting seat, and the other end is fixed to the inner wall of the slide groove, each slide groove is also fixed with a horizontally extending guide rod, and each mounting seat is slidably sleeved on the corresponding guide rod.

[0011] Furthermore, the length of the rack is smaller than the length of the side guard plate, and the height of the placement seat is higher than the side guard plate.

[0012] Furthermore, each placement seat is provided with a placement groove.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0014] The utility model arranges a linkage mechanism on one side guard plate. During the process of the conveying mechanism transporting the glass products, the linkage effect of the linkage mechanism can be utilized to drive the shaft rod, the placement seat and the glass products to rotate, so that the glass products can rotate on their own during the travel, thereby ensuring the uniformity of heat annealing of various parts of the glass products and effectively improving the crystallinity of the glass products. The self-rotation drive of the glass products comes from the linkage of the linkage mechanism, and there is no need to arrange additional drive, thereby reducing the equipment cost investment.

[0015] When the gear and the rack come into contact again, the gear is squeezed by the rack and pushes the mounting seat to slide in the slide groove. At this time, the spring is compressed, causing the gear to retreat until the teeth on the gear match and mesh with the teeth on the rack. Under the elastic reset action of the spring, the mounting seat is pushed to slide and reset, so that the teeth on the gear and the rack match and match, ensuring that the gear and the rack can be smoothly re-engaged, and the structural layout is reasonable.

[0025] See also Figure 1-Figure 5 The utility model provides an annealing device for improving the crystallinity of glass products, comprising a workbench 1, with two side guard plates 2 symmetrically fixed above the workbench 1, an annealing module 7 on the workbench 1, a conveying mechanism 3 arranged between the two side guard plates 2, the conveying mechanism 3 passes through the annealing module 7, the conveying mechanism 3 is used to convey glass products, the annealing module 7 is used to anneal the glass products by spraying flames from both sides and downward, a plurality of mounting plates 4 are arranged in an array along the conveying direction of the conveying mechanism 3, a mounting seat 5 is installed on each mounting plate 4, a vertically extending shaft rod 51 is rotatably installed on the top of each mounting seat 5, and a placement seat 6 for placing glass products is fixed at the end of each shaft rod 51, wherein a linkage mechanism 8 is provided on one side of the side guard plates 2, which is used to link the shaft rod 51 to rotate when the conveying mechanism 3 is running and conveying.

[0026] When the annealing device is used to anneal glass products, the glass products are loaded onto the placement seat 6 on the upstream side of the conveying mechanism 3. As the conveying mechanism 3 is conveyed, the glass products can be conveyed to the annealing module 7. The annealing module 7 can spray flames on the glass products from both sides and downward to achieve annealing of the glass products. At the same time, during the transportation of the glass products by the conveying mechanism 3, the linkage effect of the linkage mechanism 8 can be used to drive the shaft 51 to rotate, the placement seat 6 and the glass products to rotate, so that the glass products can rotate during the movement, thereby ensuring the uniformity of heat annealing of the glass products at all locations and effectively improving the crystallinity of the glass products.

[0027] In addition, each placement seat 6 is provided with a placement groove 61 . Placing the glass products in the placement groove 61 can prevent the glass products from sliding off the side of the placement seat 6 , thereby ensuring stability during transportation.

[0028] Specifically, the conveying mechanism 3 includes a main guide roller 31, a driven guide roller 32, a driving motor 33 and two conveying chains 35. The main guide roller 31 and the driven guide roller 32 are rotatably installed on both sides between the two side guard plates 2 respectively. The driving motor 33 is fixed on the outer surface of one side guard plate 2, and the output shaft is fixed to one end of the main guide roller 31. Two sprockets 34 are fixedly mounted on the main guide roller 31 and the driven guide roller 32. The corresponding two sprockets 34 are jointly driven with the conveying chain 35. A plurality of mounting plates 4 are fixed on the two conveying chains 35 in an array. When the driving motor 33 works, the output shaft of the driving motor 33 drives the main guide roller 31 and the sprocket 34 on the main guide roller 31 to rotate. Under the cooperation of the driven guide roller 32 and the sprocket 34 on the driven guide roller 32, the two conveying chains 35 can be driven to run synchronously, thereby driving the mounting plate 4 and the placement seat 6 to move synchronously, thereby realizing the conveying of glass products.

[0029] Specifically, the linkage mechanism 8 includes a bracket 81 and a rack 82, wherein a plurality of brackets 81 are fixed on the inner surface of one side guard plate 2, the rack 82 is fixed on the end of the bracket 81, and each shaft rod 51 is fixedly provided with a gear 83 meshing with the rack 82. During the conveying process of the glass products by the conveying mechanism 3, the gear 83 is meshed with the rack 82 to drive the gear 83 and drive the shaft rod 51 to rotate, thereby driving the placement seat 6 and the glass products thereon to rotate. The shaft rod 51 and the placement seat 6 are driven to rotate by the linkage effect of the rack 82 and the gear 83, without the need to set an additional driving source, thereby reducing the equipment cost investment.

[0030] When the gear 83 is separated from the rack 82 and then re-engages with it, since the gear 83 cannot directly engage with the rack 82, the present application makes the following improvements:

[0031] Each mounting plate 4 is provided with a slide groove 41, and each mounting seat 5 is slidably installed in the corresponding slide groove 41. A spring 42 is arranged in each slide groove 41. One end of the spring 42 is fixed to the side surface of the mounting seat 5, and the other end is fixed to the inner wall of the slide groove 41. When the gear 83 and the rack 82 contact again, the gear 83 is squeezed by the rack 82, pushing the mounting seat 5 to slide in the slide groove 41. At this time, the spring 42 is compressed, causing the gear 83 to retreat until the teeth on the gear 83 match and mesh with the teeth on the rack 82. Under the elastic reset action of the spring 42, the mounting seat 5 is pushed to slide and reset, so that the teeth on the gear 83 and the rack 82 match and match, ensuring that the gear 83 and the rack 82 can be smoothly re-engaged, and the structural layout is reasonable.

[0032] In addition, a horizontally extending guide rod 43 is fixed in each slide groove 41, and each mounting seat 5 is slidably mounted on the corresponding guide rod 43. Sliding the mounting seat 5 on the guide rod 43 plays a guiding and limiting role for the mounting seat 5, which can prevent the mounting seat 5 from falling out of the slide groove 41.

[0033] Specifically, the annealing module 7 includes an annealing hood 71 fixed on the workbench 1, flamethrowers A72 evenly distributed on the inner wall of one side of the annealing hood 71, flamethrowers B73 evenly distributed on the inner wall of the other side of the annealing hood 71, and flamethrowers C74 evenly distributed on the inner top wall of the annealing hood 71. The conveying chain 35 passes through the annealing hood 71 and operates in a circular manner. The flamethrower A72 can spray fire on the glass product from one side, the flamethrower C74 can spray fire on the glass product from the other side, and the flamethrower C74 can spray fire on the glass product from top to bottom. The flamethrowers A72, flamethrowers B73 and flamethrowers C74 are evenly distributed, which has the effect of spraying fire at multiple points, further improving the uniformity of heat annealing of the glass product.

[0034] In addition, the structure, specific working principle and corresponding supporting equipment of each flamethrower all adopt existing technologies and will not be described in detail.

[0035] Specifically, the length of the rack 82 is smaller than that of the side guard plate 2, the height of the placement seat 6 is higher than the side guard plate 2, and the placement seat 6 is higher than the top of the side guard plate 2 to avoid the placement seat 6 blocking the flame and interfering with the heating of the glass products.

[0036] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
