Description

Technical Field

[0001] The utility model relates to the technical field of glass edge grinding systems, and specifically relates to a fine grinding system for grinding four sides of glass. Background Art

[0002] When grinding the edges of glass sheets, the edge grinding is often carried out by means of an assembly line processing method. The edge grinding steps of the glass can be roughly divided into three steps. First, grind the edges of two opposite sides of the glass, then rotate the glass by 90° through a transfer mechanism, and then grind the remaining edges through an edge grinding mechanism again. As a result, the edge grinding of the glass needs to pass through three linearly arranged mechanisms, which greatly occupies space, and the transfer mechanism is prone to internal damage and is not conducive to maintenance. Therefore, a fine grinding system for grinding four sides of glass is proposed. Content of the Utility Model

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, and it can be the communication inside two elements.

[0028] Please refer to Figure 6 , a fine grinding system for grinding the four sides of glass, comprising two mutually perpendicular edge grinding structures and a deflection structure fixedly installed between the two edge grinding structures.

[0029] Please refer to Figure 2-5, the direction-changing structure includes a direction-changing box 1. A number of rolling balls 2 are clamped on the upper box surface of the direction-changing box 1. The direction-changing box 1 is a box structure with a semi-hollow interior. The rolling balls 2 can all roll freely on the direction-changing box 1. The purpose of the rolling balls 2 is to have a smaller rolling friction, which facilitates the direction-changing transportation of the glass sheet 14 on the direction-changing box. A number of telescopic rods 3 are inserted into the right end of the direction-changing box 1. The right end of the telescopic rod 3 is a disc structure, and the left end is a cylindrical structure. The cylindrical part is inserted into the right end of the direction-changing box 1. A buffer rod 4 is fixedly installed on the part of the telescopic rod 3 on the box surface side. A large spring 5 is sleeved between each buffer rod 4 and the direction-changing box 1. A number of small springs 6 are fixedly installed at the front and rear ends of the direction-changing box 1. Each side of the small springs 6 is fixedly installed with the same limiting block 7. The left side of the buffer rod 4 and the right side of the limiting block 7 are both flexible structures. The flexible structure and the large spring 5 are both to ensure a good buffer during the process of the glass sheet 14 from transportation to stopping, ensuring that the glass sheet 14 will not be damaged. And the limiting block 7 is a right-angled trapezoid structure. The opposite surfaces of the two limiting blocks 7 are bevel surfaces, and the left end distance between the two is greater than the right end distance, and the opposite tangent surfaces are made of smooth flexible material. When the glass sheet 14 passes through the limiting block 7, its width is between the maximum distance at the left end and the minimum distance at the right end of the two limiting blocks 7, and its length is between the right end of the limiting block 7 and the left end of the buffer rod 4. This positional relationship makes the glass sheet 14 squeeze the two side limiting blocks 7 when passing through the limiting blocks 7 on both sides due to the spring, causing the springs on the limiting blocks 7 to contract. When the glass sheet 14 completely passes through the limiting block 7, the limiting block 7 returns to its original state, making the glass sheet 14 unable to return to the conveyor belt 13 again. The limiting block 7 and the buffer rod 4 have a fixing effect on the left and right directions of the glass sheet 14. A fixing block 8 is fixedly installed at the front end of the direction-changing box 1. A hydraulic device 9 is installed at the upper end of the fixing block 8. The working end of the hydraulic device 9 is inserted into the front end of the direction-changing box 1. And the part of the hydraulic device 9 inside the direction-changing box 1 is connected with a push block 10. There is an anti-slip coating behind the push block 10. The function of the anti-slip coating is to prevent the glass sheet 14 from slipping when the push block 10 pushes it backward, affecting subsequent processing.

[0030] Please refer to Figure 1, the edge grinding structure includes an edge grinding frame 11. Inside the edge grinding frame 11, several rollers 12 are rotatably connected. A power device is arranged on the rollers 12 to drive the conveyor belt 13 to rotate by the rollers 12. The outer surfaces of the rollers 12 are commonly sleeved with a conveyor belt 13. A glass sheet 14 is placed above the conveyor belt 13. On both upper sides of the edge grinding frame 11, several limiting rollers 15 are rotatably connected. Both sides of the glass sheet 14 are in close contact with the limiting rollers 15. The limiting rollers 15 can limit the edge grinding of the glass sheet 14 to achieve the directional transportation of the glass sheet 14. Above the positive side of each side of the limiting rollers 15, an edge grinder 16 is arranged and installed on the edge grinding frame 11. The right end of one edge grinding structure is fixedly installed at the left end of the direction-changing structure, and the front end of the other edge grinding structure is fixedly installed at the rear end of the direction-changing structure. The edge grinding frames 11 of the edge grinding structures are all fixed to the direction-changing box 1 of the direction-changing structure, and the horizontal plane of the conveyor belt 13 is coplanar with the plane formed by the tops of several rolling balls 2 clamped on the box surface. The overall structure of this device is an L-shaped mirror flip, and the left end is the starting end of this device, and the rear end is the terminal end of this device. When the fine grinding system for grinding the four sides of the glass grinds the glass sheet 14, it sequentially passes through the edge grinding structures distributed left and right below, grinds through the transportation of the conveyor belt 13, and then makes the glass sheet 14 positioned left and right and stationary through the limiting block 7 and the buffer rod 4 on the direction-changing structure. Then, the hydraulic device 9 is used to push the glass sheet 14 backward. When the rear end of the glass sheet 14 reaches above the conveyor belt 13 of the upper edge grinding structure, the conveyor belt 13 provides the power for the backward transportation of the glass bottle to perform secondary edge grinding, so as to jointly complete the edge grinding of the glass sheet 14.

[0031] In summary: For the fine grinding system for grinding the four sides of the glass, through two mutually perpendicular edge grinding structures and a direction-changing structure fixed between the two, the transfer mechanism is omitted during the edge grinding process of the glass sheet 14. And the direction-changing box 1 is provided with a limiting block 7 and a telescopic rod 3, which have positioning and buffering functions. And through the push block 10 connected by the hydraulic device 9, the glass sheet 14 is directionally transported. This device occupies a small area, and the vertical structure is more conducive to maintenance. At the same time, the transfer mechanism is omitted, greatly improving the work efficiency.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
