Description

Technical Field

[0001] The utility model belongs to the technical field of glass deviation correction and positioning, in particular to a positioning device which is convenient for realizing the deviation correction control of glass in a wind grille. Background Art

[0002] In the glass tempering production line, rollers are usually used to transport the glass, and then to the heating and cooling steps to complete the glass tempering process. When the tempered glass is transported over a long distance, insufficient equipment accuracy or reduced equipment accuracy can easily cause the glass to deviate, especially when the tempered glass is transported in the flexible shaft wind grille.

[0003] Most of the traditional flexible shaft bending wind grille equipment is positive bending, with a mechanical structure for support under the flexible shaft, and the top of the roller is relatively flat, so the tempered glass is not prone to deviation. With the development of the times, the requirements for tempered glass are getting higher and higher, and now there are also flexible shaft reverse bending equipment. The flexible shaft reverse bending equipment requires reverse arc change, so the mechanical structure cannot be set under the flexible shaft for support, which directly leads to a decrease in the flatness above the roller, which is easy to cause the glass to deviate.

[0004] When the soft-axis bending wind grille is used as a propulsion wind grille, due to the long travel distance of the glass, it will cause a large deviation. If the position of the tempered glass is not corrected and it is directly pushed into the heating furnace, it will affect the quality of the glass, especially when making hard-axis bending glass. When the glass is pushed to the inside of the hard-axis bend after heating, once the glass is offset, it will cause the glass to deform when the arc is changed, which is difficult to meet production requirements. In addition, if the deviation of the glass is large, the glass will directly hit the side wall of the furnace in the furnace. The positioning device in the previous tempering equipment has a complex structure, which is not only costly, but also can only be used for positioning small pieces of glass, and is not suitable for positioning glass in the soft-axis bending wind grille. Utility Model Content

[0005] In order to solve the problem that the glass in the existing glass tempering production line is prone to position deviation when the soft-axis bending wind grille is pushed forward, the purpose of the utility model is to provide a positioning device that is convenient for realizing the correction control of the glass in the wind grille, and the positioning device is installed between the heating furnace and the soft-axis bending wind grille. The positioning device includes a telescopic component and a positioning component for correcting the position deviation of the glass to be tempered. It can not only realize the positioning of the tempered glass when the soft-axis bending glass is tempered, but also meet the requirements of simple structure and low cost of the positioning device, and it is convenient for maintenance.

[0006] The technical solution adopted by the utility model to achieve the above-mentioned technical purpose is: a positioning device that is convenient for realizing the glass correction control in the wind grid, the positioning device is installed between the heating furnace and the soft-axis bent wind grid, the positioning device includes a telescopic component and a positioning component for correcting the position deviation of the tempered glass, the telescopic component is arranged at the junction of the heating furnace and the soft-axis bent wind grid and is located below the roller, and the telescopic component is connected to the positioning component through a connecting component.

[0007] Further optimized, the telescopic assembly is located between the rollers of the roller table.

[0008] Further optimization, the telescopic assembly and the connecting assembly are located on the same vertical line, wherein the connecting assembly is composed of a connecting rod and a cross bar, the upper end of the telescopic assembly is connected to the lower end of the connecting rod, the upper ends of multiple connecting rods are connected to the lower part of the cross bar, and the upper part of the cross bar is distributed with positioning assemblies.

[0009] Further optimized, the positioning components are evenly distributed on the cross bar.

[0019] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described in combination with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment in the utility model, all other embodiments that can be easily changed or replaced by ordinary technicians in the field without creative work are within the scope of protection of the utility model. The structures, proportions, sizes, etc. shown in the drawings of the specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions that can be implemented in the utility model, so they have no technical substantive significance. Any modification of the structure, change of the proportional relationship or adjustment of the size should still fall within the scope of the technical content disclosed in the utility model without affecting the effect and purpose that can be achieved by the utility model.

[0020] At the same time, it should be noted that, unless otherwise specified, "multiple" means two or more; the directions or positional relationships indicated by the terms "upper", "lower", "left", "right", "front end", "rear end", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. Changes or adjustments in their relative relationships shall also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0021] A positioning device is provided for realizing the correction control of glass in a wind grid. The positioning device is installed between a heating furnace 1 and a flexible shaft bending wind grid 2. The position deviation of the tempered glass to be tempered is corrected before the tempered glass enters the heating furnace 1. On the one hand, it is avoided that the position is corrected too early, which may cause the need to repeat the correction operation if the position deviation occurs again later, thereby saving costs. On the other hand, after the position deviation is corrected, the tempered glass 8 is directly pushed into the heating furnace by a roller 3, thereby maximizing the glass quality and reducing the deviation rate. The positioning device includes a telescopic component 4 and a positioning component 7 for correcting the position deviation of the tempered glass 8. The positioning component 7 for correcting the position deviation of the tempered glass 8 can be flexibly lifted and lowered by matching the telescopic component 4, thereby meeting the reverse arc change requirements of the flexible shaft reverse bending equipment for producing bent glass. The telescopic component 4 is arranged at the junction of the heating furnace 1 and the flexible shaft bending wind grid 2 and is located below the roller 3. The telescopic component 4 is connected to the positioning component 7 through a connecting component. The arrangement of the positioning device does not affect the normal operation of the heating furnace 1, the flexible shaft bending wind grid 2 and the roller 3. The simple structure also reduces the production cost.

[0022] Example 1

[0023] A positioning device for realizing the correction control of glass in the wind grille, such as Figure 1 and Figure 2 As shown, when the positioning device is not working, the positioning device is located between the heating furnace 1 and the soft shaft bending wind grid 2, and the telescopic component 4 of the entire positioning device is located below the roller 3 through the connecting component and the positioning component 7 used to correct the position deviation of the tempered glass 8. When the tempering production starts, the tempered glass 8 enters the soft shaft bending wind grid from the plate, and continues to move forward according to the advancement distance set by the computer. Once the low-speed advancement begins, the positioning device rises under the action of the telescopic component 4, and the positioning component 7, which often uses a block in production, rises vertically through the connecting component. The tempered glass 8 moves forward until it hits the positioning component 7. With the continued rolling of the roller 3 and the fixed blocking of the positioning component 7, the position of the glass is corrected. After the glass is straightened, the roller 3 stops working, that is, stops pushing the glass forward. The positioning component 7 drops to the bottom of the roller 3 through the telescopic component 4 and returns to the initial position. The roller 3 continues to work and continues to push the glass forward until the glass moves to a suitable position and waits to enter the heating furnace.

[0024] Example 2

[0025] This embodiment is an improved solution based on the embodiment 1. Its main structure is the same as that of the embodiment 1. The improvement is as follows: Figure 1 and Figure 2As shown, the telescopic assembly 4 is located between the rollers of the roller 3. The rollers of the roller 3 can ensure that the telescopic assembly 4 is not easily blocked during the telescopic process, and avoid the telescopic assembly 4 from rubbing against the rollers of the roller 3, which not only affects the effect of correcting the position deviation of the glass, but also easily causes damage to the rollers of the roller 3, which has an adverse effect on the advancement of the glass.

[0026] like Figure 1 and Figure 3 As shown, the telescopic assembly 4 and the connecting assembly are located on the same vertical line, wherein the connecting assembly is composed of a connecting rod 5 and a cross bar 6, the upper end of the telescopic assembly 4 is connected to the lower end of the connecting rod 5, the upper ends of multiple connecting rods 5 are connected to the lower part of the cross bar 6, and the upper part of the cross bar 6 is distributed with a positioning assembly 7. The telescopic assembly 4 controls the lifting and lowering of the cross bar 6 through the connecting rod 5, and controls the lifting and lowering of the positioning assembly 7 through the cross bar 6, so the positioning assembly 7 can be directly controlled by the telescopic assembly 4, and the entire positioning device realizes the free lifting and lowering of the positioning assembly 7.

[0027] Example 3.

[0028] This embodiment is an improved solution based on the embodiment 1. Its main structure is the same as that of the embodiment 1. The improvement is as follows: Figure 3 As shown, the positioning components 7 are evenly distributed on the crossbar 6. The even arrangement of the positioning components 7 can ensure that when the positioning block is raised, the position deviation of the tempered glass 8 is effectively corrected and the deviation rate is reduced.

[0029] like Figure 3 As shown, the cross bar 6 controls the displacement of the positioning assembly 7 under the push of the telescopic assembly 4 through the connection of the connecting rod 5. The simple structure of the integrated positioning device can realize the direct control of the positioning assembly 7 through the telescopic assembly 4, and the entire positioning device can realize the free lifting and lowering of the positioning assembly 7. The overall structure of the positioning device is simple and convenient for subsequent maintenance, while reducing the production cost and maintenance cost.

[0030] It should be noted that the connection assembly described in the present invention including its structure is not a limitation of the present invention. Based on this purpose, those skilled in the art can use other similar mechanical structures to realize the direct control of the telescopic assembly 4 on the lifting and lowering of the positioning assembly 7.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the same. Those skilled in the art should understand that the specific implementation methods of the present invention can be modified or replaced by equivalents with reference to the above embodiments. Any modifications or equivalent replacements that do not depart from the spirit and scope of the present invention are within the scope of protection of the claims of the present invention.
