Description
Technical Field
[0001] This utility model relates to the field of glass polishing technology, specifically to a shock-absorbing device for the production of refrigerator glass partition edge polishing. Background Technology
[0002] Food stored in the refrigerator should have some space between them and should not be placed against the left, right, or back walls of the refrigerator to allow for air convection. The refrigerator should not be overfilled. The glass shelves in the refrigerator serve to separate food and also improve the utilization of the internal space. When manufacturing refrigerator glass shelves, the edges of the cut glass need to be polished to prevent scratches to users and to improve the appearance.
[0003] The core objective of refrigerator glass shelf edge grinding is to eliminate sharp edges and burrs produced after glass cutting through mechanical processing, thereby improving product safety and aesthetics. Existing production lines generally use CNC edge grinding machines, which grind the glass edges with diamond grinding wheels. During grinding, operators need to accurately place the glass cover plate on the suction plate, then fix the refrigerator glass shelf with negative pressure, and then grind the edges of the refrigerator glass shelf with diamond grinding wheels. Fixing takes a lot of time, reducing the speed of refrigerator glass shelf production on the assembly line. Moreover, the glass vibrates during grinding, and after fixing, different parts of the glass will have different vibration amplitudes. The dynamic load caused by different vibration amplitudes will cause stress concentration inside the glass, and the edges and weak areas are prone to surface cracks, resulting in an increased glass damage rate.

[0008] Several rotating shafts are rotatably arranged between the two fixed slot plates. Several guide wheels are provided on the rotating shafts, and sprocket pairs are provided at the ends of the rotating shafts.

[0011] With the above structure, rotating the two locking screws disconnects them from the support block. Rotating the L-shaped plate causes the grinding assembly to rotate, making it easy to replace parts of the grinding assembly.
[0012] The grinding assembly includes a grinding motor, which is fixed on an L-shaped plate, and a grinding disc is fixed on the output shaft of the grinding motor.
[0013] With the above structure, the grinding motor drives the grinding disc to rotate through the output shaft, the glass moves to the grinding disc, and the grinding disc grinds the edges of the glass.
[0014] Compared with the prior art, the beneficial effects of this utility model are: This vibration damping device for refrigerator glass shelf edge grinding production can adjust the position of the extrusion plate according to the vibration amplitude during glass grinding.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] like Figures 1-5As shown, this utility model provides a technical solution: a shock-absorbing device for the production of refrigerator glass partition edge grinding, including four support legs 8, which are arranged in pairs. A fixing rod 5 is fixed between each pair of support legs 8. Two fixing groove plates 7 are fixed above the four support legs 8. A shock-absorbing component is provided above the fixing groove plates 7. The shock-absorbing component includes two first fixing blocks 14 and two second fixing blocks 16. The first fixing blocks 14 and the second fixing blocks 16 are respectively fixed on the fixing groove plates 7 at corresponding positions. A limit rod 13 is fixed between the first fixing blocks 14 and the corresponding second fixing blocks 16. A number of guide blocks 18 are slidably arranged on the limiting rod 13. A connecting plate 19 is fixed below the guide blocks 18. Two limiting sleeve rods 26 and two adjusting screws 22 are fixed below the connecting plate 19. A handwheel 21 is fixed above the adjusting screws 22. A pressing plate 27 is fixed at the end of the two limiting sleeve rods 26. Two telescopic sleeve rods 23 are fixed above the pressing plate 27. An adjusting block 25 is fixed above the two telescopic sleeve rods 23. A spring 24 is sleeved on the telescopic sleeve rods 23. The adjusting screws 22 are rotatably mounted on the adjusting block 25. A grinding assembly is arranged above the fixed groove plate 7.
[0019] A horizontal cross-section is provided above the limiting rod 13, and a fixing screw 20 is threadedly connected to the top of several guide blocks 18. The end of the fixing screw 20 abuts against the top of the limiting rod 13. When the fixing screw 20 is rotated, the fixing screw 20 moves downward and the end of the fixing screw 20 abuts against the top of the limiting rod 13, thereby fixing the guide block 18 above the limiting rod 13. The horizontal cross-section facilitates the locking of the fixing screw 20.
[0020] Several rotating shafts 6 are rotatably arranged between two fixed slot plates 7. Several guide wheels 10 are arranged on the rotating shafts 6. The ends of the rotating shafts 6 are provided with sprocket pairs. A conveyor motor 9 is fixed to the side of one of the fixed slot plates 7. The output shaft of the conveyor motor 9 is connected to one of the rotating shafts 6 through a coupling. When the glass is placed on the guide wheels 10, the conveyor motor 9 drives one of the rotating shafts 6 to rotate through its output shaft. One of the rotating shafts 6 drives the other rotating shafts 6 to rotate synchronously through the sprocket pairs. The several rotating shafts 6 drive the several guide wheels 10 to rotate, and the several guide wheels 10 drive the glass to move.
[0021] A mounting plate 4 is detachably and adjustable above each of the two fixed mounting plates 7. The two mounting plates 4 are symmetrical to each other. Several guide rollers 3 are rotatably arranged inside the mounting plates 4. Two support blocks 17 are fixed inside the mounting plates 4. An L-shaped plate 11 is rotatably arranged above the mounting plates 4. Two locking screws 15 are rotatably arranged on the L-shaped plate 11. The two locking screws 15 are threadedly connected to the support blocks 17 at corresponding positions. A dust collection box 12 is fixed to the side of the mounting plates 4. Rotating the two locking screws 15 releases the connection between the two locking screws 15 and the support blocks 17. Rotating the L-shaped plate 11 causes the grinding assembly to rotate, which facilitates the replacement of parts of the grinding assembly. The dust collection box 12 can be connected to a dust collection device to collect and process the debris during grinding.
[0022] The polishing assembly includes a polishing motor 1, which is fixed on an L-shaped plate 11. A polishing disc 2 is fixed on the output shaft of the polishing motor 1. The polishing motor 1 drives the polishing disc 2 to rotate through the output shaft. The glass moves to the polishing disc 2 and the polishing disc 2 polishes the edge of the glass.
[0023] The working principle of this utility model: Glass is placed on several guide wheels 10. A conveyor motor 9 drives one of the rotating shafts 6 via its output shaft. This rotating shaft 6 drives the other rotating shafts 6 to rotate synchronously via a sprocket pair. The rotating shafts 6 drive the guide wheels 10 to rotate, which in turn move the glass. The glass moves to below the extrusion plate 27. A grinding motor 1 drives a grinding disc 2 to rotate via its output shaft. The glass moves to the grinding disc 2, which grinds the glass edges. During grinding, vibrations from the glass edges are transmitted to the entire surface, with the vibration amplitude gradually decreasing from the edge to the center. The damping components are adjusted according to the vibration amplitude. Rotating the fixing screw 20 moves the screw upwards, releasing the locking of the guide block 18. Moving the guide block 18 adjusts the position of the extrusion plate 27. Rotating the fixing screw 20 moves the screw downwards, fixing the plate. The end of the screw 20 abuts against the upper part of the limiting rod 13, thereby fixing the guide block 18 above the limiting rod 13. Turning the handwheel 21 causes the adjusting screw 22 to rotate, which in turn presses the pressing plate 27. The pressing plate 27 compresses the spring 24, enhancing the buffering capacity of the pressing plate 27. When the vibration of the glass is transmitted to the pressing plate 27, the pressing plate 27 transmits the vibration to the telescopic sleeve 23 and the spring 24. The telescopic sleeve 23 and the spring 24 buffer and absorb the vibration of the pressing plate 27, eliminating the need to fix the glass. This reduces the time required for glass edge grinding, increases the speed of refrigerator glass partition production on the assembly line, and absorbs and buffers the vibration during glass grinding, reducing the glass damage rate. After grinding one side of the glass, it can be flipped over and placed on several guide wheels 10 as needed, so that the other side can be ground again.
[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
