Description

Technical Field

[0001] This utility model relates to the field of glass processing equipment technology, and in particular to a cleaning device for glass after it is broken online. Background Technology

[0002] In float glass production, edge-pulling rollers are used to apply appropriate tension to both sides of the glass to ensure that the width and thickness of the glass remain within the required production range. During this process, the edge-pulling rollers leave marks on the glass edges, which naturally need to be cut and broken off. This process is called edge cleaning in the cold-end section. It is usually done using an edge cleaning machine. Before passing through the edge cleaning machine, the glass edges have already been cut by a longitudinal cutting bridge, then by a transverse cutting bridge, and finally broken off to the required length. At this point, the glass is suspended on both sides. The pressure roller mechanism above the edge cleaning machine presses down, breaking off the passing glass edges, which fall into the edge cleaning machine's hopper and finally enter the glass breakage system.

[0003] Existing technical problems:

[0004] Edge cleaning machines typically use a cylinder to drive a single pressure roller to break the glass edges. In this process, the pressure roller only contacts the glass surface at a single point, while the lower glass contacts multiple rollers. Even if a contact point is aligned vertically with the upper contact point, the glass experiences a momentary force during edge cleaning. Uneven force distribution can cause uneven edge breaking, resulting in raised or recessed flanges. Even if the upper mechanism is replaced with a rod-type mechanism, allowing the entire glass surface to contact the upper surface, the lower rollers still only make point contact, still producing raised or recessed flanges. This renders the glass unusable and requires edge trimming. Thicker glass is more prone to uneven stress during annealing, and after the compressive stress at the edges is removed, the resulting cracks will not open vertically as ideally. Therefore, edge cleaning is more difficult for thicker glass. In actual production of glass thicker than 15mm, manual edge cleaning is necessary, further increasing costs. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention proposes a device for repairing the edges of glass after it has been broken online.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a glass edge-cleaning device after online glass breakage, characterized in that it includes two symmetrically arranged grinding structures at the upper and lower ends of the side of the glass plate; the grinding structure includes a mounting plate and a swing arm, the mounting plate is fixed on the glass conveyor, a slide rod is fixedly provided at the lower end of the mounting plate, a sliding sleeve is slidably connected on the slide rod, a tension spring connecting the mounting plate and the sliding sleeve is sleeved on the slide rod, a grinding wheel with a conical grinding surface is rotatably connected to the middle of the swing arm, one end of the swing arm is fixedly connected to the sliding sleeve, and a compression spring is connected between the other end of the swing arm and the mounting plate; the grinding wheel is connected to the output shaft of a motor.

[0007] Furthermore, a drive shaft is fixedly mounted on the axle of the grinding wheel, and the drive shaft has spiral guide ribs on its exterior.

[0008] After the glass edge is broken off, the main board continues to move along the line, while the edge material is separated and recycled. This edge-cleaning device is located at the corresponding position on the glass conveyor after the glass is broken off. It includes two grinding structures, symmetrically arranged on the upper and lower sides of the glass main board edge, respectively grinding the upper and lower sides of the glass. Of course, multiple upper grinding structures and multiple lower grinding structures can be set as needed. When the glass edge approaches the grinding wheel, the concave and convex edges of the edge can be cleaned by the lateral squeezing and rotation of the grinding wheel, making the edge... Sharp edges and shavings are cleaned; when the glass side cannot be effectively pressed against the grinding wheel, the spring drives the swing arm to swing down around the drive shaft, the grinding wheel presses down, and the guide rib on the drive shaft can contact the glass surface, thereby driving the entire swing arm to move a certain distance inward to the glass. At the same time, the distance between the grinding surface of the grinding wheel and the glass side decreases. In this way, when the glass side is uneven, it can ensure that the grinding wheel maintains pressure on the glass side, ensuring continuous edge grinding without interruption, and that all parts of the glass side can be effectively ground.

[0012] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0013] like Figure 1 and Figure 2 As shown, the edge-cleaning device after the glass is broken online includes two symmetrically arranged grinding structures at the upper and lower ends of the glass plate. Each grinding structure includes a mounting plate 1 and a swing arm 2. The mounting plate 1 is fixed to the glass conveyor frame. A slide rod 3 is fixedly installed at the lower end of the mounting plate 1, and a sliding sleeve 4 is slidably connected to the slide rod 3. A tension spring 5 connecting the mounting plate 1 and the sliding sleeve 4 is fitted on the slide rod 3. A grinding wheel 6 with a conical grinding surface is rotatably connected to the middle of the swing arm 2. One end of the swing arm 2 is fixedly connected to the sliding sleeve 4, and a compression spring 7 connects the other end of the swing arm 2 to the mounting plate 1. The grinding wheel 6 is connected to the output shaft of a motor. A drive shaft 8 is fixedly installed on the axle of the grinding wheel 6, and the drive shaft 8 has spiral guide ribs 9 on its exterior.

[0014] After the glass edge is broken off, the main board continues to move along the line, while the edge material is separated and recycled. This edge-cleaning device is located at the corresponding position on the glass conveyor after the glass is broken off. It includes two grinding structures, symmetrically arranged on the upper and lower sides of the glass main board edge, respectively grinding the upper and lower sides of the glass. Of course, multiple upper grinding structures and multiple lower grinding structures can be set as needed. When the glass edge approaches the grinding wheel, the concave and convex edges of the edge can be cleaned by the lateral squeezing and rotation of the grinding wheel, making the edge sharp and smooth. The residue is cleaned up; when the glass side cannot be effectively pressed against the grinding wheel, the compression spring 7 drives the swing arm 2 to swing down around the drive shaft 8, the grinding wheel 6 presses down, and the guide rib 9 on the drive shaft 8 can contact the glass surface, thereby driving the entire swing arm 2 to move a certain distance towards the inside of the glass. At the same time, the distance between the grinding surface of the grinding wheel and the glass side decreases. In this way, when the glass side is uneven, it can be ensured that the grinding wheel maintains pressure on the glass side, ensuring continuous edge grinding without interruption, and all parts of the glass side can be effectively ground.

[0015] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
