Description

Technical Field

[0001] This utility model belongs to the field of tempered glass edge grinding and cleaning, specifically, it relates to a tempered glass edge grinding and cleaning device. Background Technology

[0002] When tempered glass is cut, tiny, barely perceptible cracks, chips, and edge breakage inevitably occur at its edges. These untreated, defective, sharp edges become stress concentration points. When subjected to external force, temperature changes, or even a slight release of internal stress, enormous stress will preferentially be released at these most vulnerable points, causing the cracks to propagate instantly and leading to spontaneous glass breakage. Edge grinding transforms these sharp, defective edges into smooth, rounded shapes. This rounded transition effectively disperses and eliminates stress concentration, significantly reducing the risk of spontaneous breakage due to edge defects and ensuring its safety and stability. After edge grinding, tempered glass often has a significant amount of glass powder concentrated at the edges. To prevent this glass powder from affecting the use of tempered glass, the edges usually need to be cleaned to remove the glass powder.

[0003] After tempered glass undergoes edge grinding, it is typically cleaned with a brush, followed by a strong airflow to dry the edges and remove residual glass powder. However, the airflow from existing nozzles is usually constant when cleaning the edges of tempered glass. This can cause the glass powder on the edges to remain under constant pressure, resulting in the powder remaining in a specific position and difficult to blow off the edges. Utility Model Content

This causes the impact force on the glass powder at the edge of the tempered glass to change continuously, which is more conducive to blowing the glass powder off the edge of the tempered glass.

[0017] This embodiment discloses a tempered glass edge grinding and cleaning device, such as... Figures 1-7 As shown, it may include: Conveyor assembly 100; A cleaning assembly 200 includes a spray unit 210, at least two brushing units 230, and at least two blowing units 240. The spray unit 210, brushing unit 230, and blowing unit 240 are spaced apart from each other. The blowing unit 240 includes an elastic rod 241, a rotating drum 242, and an air nozzle 243. The outer peripheral surface of the rotating drum 242 is elliptical in projection along its axial direction. The inner peripheral surface of the rotating drum 242 is rotatably connected to the outer peripheral surface of the elastic rod 241. The air nozzle 243 is connected to the elastic rod 241. One end of the elastic rod 241 along its axial direction is connected to the conveying assembly 100. The spray unit 210 and brushing unit 230 are respectively connected to the conveying assembly 100. A conveying channel is formed between the two brushing units 230 and between the two blowing units 240. The air outlet of the air nozzle 243 faces the conveying channel.

[0018] In this embodiment, by projecting the outer peripheral surface of the rotating drum 242 along its axial direction into an ellipse, when the tempered glass is conveyed in the conveying channel, it contacts the outer peripheral surface of the rotating drum 242, causing the rotating drum 242 to move the air nozzle 243 closer to or further away from the edge of the tempered glass during rotation. This creates a changing airflow, causing the impact force on the glass powder at the edge of the tempered glass to change continuously, which is more conducive to blowing the glass powder off the edge of the tempered glass. In this embodiment, the number of blowing and washing units 240 can be set according to the actual situation, thereby facilitating the removal of glass powder from the edge of the tempered glass.

[0019] In some embodiments of this utility model, such as Figure 2 , Figure 3 , Figure 6 , Figure 7 As shown, the elastic rod 241 includes a rod body portion 2411 and a second connecting portion 2412; one end of the second connecting portion 2412 is fixedly connected to the outer peripheral surface of the rod body portion 2411, and the other end is connected to the air nozzle 243; one end of the rod body portion 2411 along its axial direction is connected to the conveying assembly 100; the outer peripheral surface of the rod body portion 2411 is rotatably connected to the inner peripheral surface of the rotating drum 242; the connecting portion is located between the rotating drum 242 and the conveying assembly 100.

[0020] In this embodiment, the rod body 2411 and the conveying assembly 100 can be connected by welding and then threaded connection. It should be noted that in this embodiment, the rod body 2411 can have a certain elasticity, so that when the rotating drum 242 is squeezed by the edge of the tempered glass, it can produce a certain elastic deformation, so that the air nozzle 243 can move relative to the tempered glass.

[0021] In some embodiments of this utility model, such asFigure 6 , Figure 7 As shown, the rotating drum 242 includes a rigid part 2421 and a soft part 2422; the outer peripheral surface of the rigid part 2421 is fixedly connected to the inner peripheral surface of the soft part 2422; the projection of the outer peripheral surface of the soft part 2422 along its axial direction is elliptical; the inner peripheral surface of the rigid part 2421 is rotatably connected to the outer peripheral surface of the rod part 2411.

[0022] In this embodiment, by setting the rotating cylinder 242 as a combination of a hard part 2421 and a soft part 2422, the soft part 2422 can be a rubber material with a certain hardness. When the soft part 2422 comes into contact with the edge of the tempered glass, it can avoid hard contact with the tempered glass and prevent damage to the tempered glass.

[0023] In some embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the conveying assembly 100 includes a frame unit 110 and a conveying unit 120; the frame unit 110 includes a conveying frame 111, a guide box 112, a guide pipe 113, and a water pipe frame 114; the guide box 112 is connected to the conveying frame 111; a guide groove is provided inside the guide box 112; the guide groove is located below the conveying channel and communicates with the conveying channel; one end of the rod body 2411 along its axial direction is fixedly connected to the end face of the guide box 112 located below the conveying channel; the guide pipe 113 is fixedly connected to the guide box 112 and communicates with the guide groove; the water pipe frame 114 is connected to the conveying frame 111 and is above the conveying channel; the spray...

[0024] In this embodiment, the conveyor motor 121 is electrically connected to an external controller (not shown in the figure). The external controller can control the air nozzle 243 and supply water to the spray unit 210. Since the controller is a conventional technical application, this embodiment will not specifically describe the combination of the controller and other conventional existing equipment to achieve the functions described in this utility model. The brushing unit 230 is a brush that can rotate with the conveyor roller 122 to brush the edge of the tempered glass. In this embodiment, the bristles on two adjacent brushing units 230 in the conveying channel direction can be arranged to contact each other, so that the contacting bristles can remove glass powder from each other during the rotation of the brushing unit 230, thereby achieving self-cleaning of the bristles to a certain extent and improving the brushing efficiency of the bristles on the edge of the tempered glass.

[0025] In some embodiments of this utility model, such as Figure 1 , Figure 2 As shown, the spray unit 210 includes a spray pipe 211 and a plurality of nozzles 212; the spray pipe 211 is connected to the water pipe frame 114; the nozzles 212 are connected to the spray pipe 211; the nozzles of the nozzles 212 face the conveying channel.

[0026] In this embodiment, the cleaning fluid can be sprayed onto the edge of the tempered glass through the nozzle 212 in the spray unit 210, thereby cleaning the edge of the tempered glass.

[0027] In some embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 8 , Figure 9 As shown, the cleaning assembly 200 further includes two correction units 220; the two correction units 220 are respectively located on both sides of the conveying channel along its conveying direction; each correction unit 220 includes a correction plate 221, a plurality of correction rollers 222, and a correction belt 223; the correction plate 221 is connected to the conveying frame 111; the correction rollers 222 are rotatably connected to the correction plate 221; adjacent correction rollers 222 are spaced apart; the correction belt 223 is drive-connected to the correction rollers 222; the correction belt 223 is spaced apart from the correction plate 221; the distance between the correction plate 221 and the conveying channel gradually decreases along the conveying direction of the conveying channel; the correction belt 223 is spaced apart from the conveying channel; the axial direction of the conveying roller 122 is perpendicular to the conveying direction of the conveying roller 122.

[0028] The correction plate 221 includes a first connecting part 2211 and a spring part 2212; the first connecting part 2211 is connected to the conveyor frame 111; one end of the first connecting part 2211 along the conveying direction of the conveying roller 122 is fixedly connected to the spring part; the distance between the spring part 2212 and the first connecting part 2211 along the conveying direction of the conveying roller 122 gradually increases; the correction roller 222 is rotatably connected to the spring part 2212.

[0029] In this embodiment, by setting the correction unit 220, the tempered glass can come into contact with the correction belt 223 after it tilts during the tempered glass conveying process. The correction belt 223 can apply a force perpendicular to the extension direction of the conveying channel to the tempered glass, thereby playing a certain role in correcting deviation.

[0030] In some embodiments of this utility model, such as Figure 1 , Figure 2 As shown, the angle between the guide box 112 and the horizontal plane along the conveying direction of the conveying roller 122 is 5° to 10°.

[0031] As described above, the tempered glass edge cleaning equipment can only clean both sides of the tempered glass at a time. However, the equipment can be used to clean different sides of the tempered glass multiple times to remove glass powder from the edges of the tempered glass.

[0032] In this embodiment, by setting the flow box 112 in an inclined structure, it is easy for the cleaning fluid and glass powder to be discharged from the flow pipe 113.

[0033] The working principle of this utility model is as follows: By turning on the conveyor motor 121, supplying cleaning fluid to the spray pipe 211, and venting air to the air nozzle 243, the edge-ground tempered glass is then placed on the conveyor roller 122 in a predetermined manner. The conveyor roller 122 moves the tempered glass to the blowing unit 240 and contacts the outer surface of the rotating drum 242, driving the rotating drum 242 to rotate. During the rotation of the rotating drum 242, the air nozzle 243 moves away from or closer to the tempered glass, thereby forming a relatively changing blowing force to remove glass powder from the edge of the tempered glass.

[0034] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes can be made in form and detail without departing from the spirit and scope of this disclosure.
