Description

Technical Field

[0001] The utility model belongs to the field of glass production, and in particular relates to a glass cleaning device. Background Art

[0002] The processing of engineering glass involves the transportation between various processes such as cutting, edging, tempering, coating, hot dipping, tempering, hollowing, and interlayering. In order to avoid scratches and breakage of the glass during transportation, cork pads or cardboard are pasted between the lower glass of each process, and the cork pads or cardboard need to be manually removed at the upper position of the next process. However, manual removal of cork pads or cardboard on the glass surface is labor-intensive and affects the production continuity of the entire line. If the cork pads or cardboard are not removed, the cork pads or cardboard enter the circulation system of the cleaning machine, causing pipe blockage, reducing the cleaning quality of the cleaning machine, and failing to meet the production process requirements. Therefore, the cleaning machine needs to be cleaned and maintained frequently.

[0003] In order to avoid scratches on float glass and coated glass, sandblasting isolation powder is applied on the glass surface. Once this substance enters the circulation system of the cleaning machine, it is very easy to cause blockage of the cleaning machine's pipes and form silt-like greasy substances around the cleaning machine's water tank, causing quality defects such as roller marks on the glass surface after the cleaning machine, thereby reducing the cleaning quality.

DETAILED DESCRIPTION

[0033] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0034] See also Figures 1 to 12 The glass cleaning device shown comprises a bracket 9, a pressing component, and a scraping component, wherein:

[0035] In this example, the glass is transported through a conveying assembly (the conveying assembly includes a plurality of conveying rollers 12 extending along the Y-axis, a transmission wheel 13 arranged on the conveying rollers 12, and a motor connected to the conveying rollers 12). The glass moves along a direction (such as the X-axis). The conveying assembly is arranged on a frame 11, and a space is opened on the bracket 9 for the frame 11 to pass through.

[0036] The scraping assembly is connected to the bracket 9, and the scraping assembly includes a scraper 4, which extends in a direction perpendicular to the glass transmission direction (Y axis), and is located below the glass to be cleaned. The upper end of the scraper 4 can be against the support pad under the glass to scrape off the support pad (cork pad or cardboard), and the scraper 4 scrapes off the cork pad or cardboard during the glass transmission, and the scraper 4 does not contact the lower surface of the glass. The glass is basically in a horizontal state during the transmission process, and a scraper 4 is set below the glass to scrape off the support pad under the glass. Therefore, the distance between the upper end of the scraper 4 and the glass must be adjusted, and the preferred distance is 0.5-1mm, which is less than the thickness of the cork pad (2-3mm), and the effect is better.

[0037] In some embodiments, the upper end of the scraper 4 has a pointed tip, and the pointed tip has an inclined surface. The inclined surface extends upward from the lower end to the upper end of the scraper 4 in an inclined direction opposite to the glass conveying direction, that is, the inclined surface extends upward from the lower end to the upper end of the scraper 4 in an inclined direction away from the blowing assembly. The inclined surface is provided to facilitate scraping the support pad under the glass.

[0038] In some embodiments, see Figure 8-11 The scraper 4 includes a first section and a second section 43 connected to each other. The first section is located above the second section 43.

The lower edge of the first inclined surface 41, the lower edge of the second inclined surface 42 are connected to the second section 43. An acute angle is formed between the first inclined surface 41 and the second inclined surface 42. The second section 43 is in a rectangular shape.

[0039] When the scraper 4 scrapes the support pad under the glass, the glass and the support pad are easy to tilt during the transmission, resulting in the inability to scrape the support pad. A pressing assembly is specially provided, which includes a pressure roller 5 and a driving member 6. The pressure roller 5 is located above the transmission assembly, the pressure roller 5 is located above the glass, and the pressure roller 5 extends in a direction perpendicular to the glass transmission direction (Y axis). The pressure roller 5 is used to press down the glass located on the transmission assembly. The driving member 6 is connected to the pressure roller 5 to drive the pressure roller 5 to move in the vertical direction. The pressure roller 5 can be adjusted according to different glass thicknesses. The pressure roller 5 is pressed against the upper surface of the glass. The glass is smoothly transmitted due to the extrusion of the pressure roller 5 during the transmission process, ensuring that the scraper 4 can smoothly scrape the support pad under the glass.

The fan provides wind, and the wind passes through the connecting pipe and the air outlet 101 of the wind knife 1 and blows toward the glass.

[0045] In order to further ensure that the isolation powder on the upper surface of the glass is cleaned up, the structure, blowing angle, wind pressure, etc. of the wind knife 1 can be adjusted. If a plurality of air outlets 101 are provided on the wind knife 1, the line connecting the plurality of air outlets 101 extends axially along the wind knife 1, and an acute angle is formed between the line connecting the plurality of air outlets 101 and the horizontal plane where the glass is located, such as preferably 8°; the outlet pressure of the wind knife 1 is 300-500Kpa (preferably 400Kpa), which can ensure that the isolation powder on the surface of the glass is blown away clean.

[0046] The connecting pipe 2 in this example can be elbow-shaped, that is, the connecting pipe 2 includes a first pipe 21, a second pipe 22, and a third pipe 23 connected in sequence, the first pipe 21 and the third pipe 23 are respectively arranged on opposite sides of the second pipe 22, the second pipe 22 extends in the vertical direction, the first pipe 21 and the third pipe 23 extend in the horizontal direction, the third pipe 23 is connected to the wind knife 1, and the first pipe 21 is connected to the fan; the wind knife 1 is cylindrical.

[0047] The device further comprises a support plate 10, which may be in the shape of a long strip, connected to the bracket 9, and connected to the blowing assembly to support the blowing assembly. Figure 6 One end of the support plate 10 is connected to the bracket 9, and the other end of the support plate 10 is provided with a through hole, through which one end of the connecting pipe 2 or the wind knife 1 passes, and the blowing assembly is fixed by the support plate 10, so that the device is more stable.

[0048] The device further comprises a beam sensor 14 and a fixing plate 15.

[0049] See also Figure 6-7 The bracket 9 includes a first longitudinal rod, a second longitudinal rod 91, a first crossbar 92, and a second crossbar 93. The first longitudinal rod and the second longitudinal rod both extend in the vertical direction. The first longitudinal rod and the second longitudinal rod are arranged opposite to each other. The first crossbar 92 and the second crossbar 93 are connected between the first longitudinal rod and the second longitudinal rod. The first crossbar 92 and the second crossbar 93 are perpendicular to the first longitudinal rod and the second longitudinal rod 91. The first crossbar 92 is located above the second crossbar 93. The first crossbar 92 and the second crossbar 93 are arranged in parallel. The first crossbar 92 and the second crossbar 93 both extend in a direction perpendicular to the glass transmission direction (Y axis); the scraper 4 is connected to the second crossbar 93 (a connection method is: corresponding mounting holes are opened on the scraper 4 and the second crossbar 93, and the scraper 4 is connected to the second crossbar 93 by installing fasteners in the mounting holes), the blowing assembly is connected to the first longitudinal rod and the second longitudinal rod 91, the pressing assembly is connected to the first crossbar 92, or the pressing assembly is connected to the first longitudinal rod and the second longitudinal rod 91.

[0050] The device of this example is used as follows:

[0051] The installation and setting of this device is as follows Figure 1, assuming that the transmission direction of the glass is as indicated by the arrow, the driving shaft of the driving member 6 is in a retracted state under normal conditions. When the opposing sensor 14 senses the front end of the glass, the pressure roller 5 starts to descend after a delay of 1S, and the fan is started after a delay of 2s (the time can be adjusted according to the production site conditions), so that the pressure roller 5 just presses the upper part of the front end of the glass. In this way, the glass is smoothly transmitted during the transmission process due to the extrusion of the pressure roller 5, and the scraper 4 is only 0.5-1mm away from the glass surface, which is less than the thickness of the cork pad (2-3mm). The scraper 4 will hang the cork pad or paper skin during the glass transmission; when the glass passes through the wind knife 1, the wind knife 1 can blow away foreign objects such as paper scraps and isolation powder on the upper surface of the glass surface. When the tail of the glass leaves the opposing sensor 14, the driving shaft of the driving member 6 starts to retract after a delay of 1S (the time can be adjusted according to the production site conditions), and the fan is turned off after a delay of 180s (the default is that the line has been stopped and the fan is automatically turned off to reduce power consumption). Because the isolation powder and paper skin on the glass surface are all cleared around this device.

[0052] The device in this example removes foreign matter such as cork pads, dust particles, etc. on the glass surface online before cleaning, thereby improving the maintenance cycle and quality of the cleaning machine, reducing the workload of workers, and improving equipment continuity; the recovered isolation powder is reused to reduce waste; the structure is simple, easy to install, process and maintain, and easy to use, which greatly reduces the intensity of manual labor and improves production efficiency. The normal glass loading cycle is 20-25S / piece, and the time required to manually remove the cork pad is at least 3S / piece, and there are certain safety hazards. After using this device, the efficiency is increased by at least 12% (3 / 25), and the actual production continuity is increased by more than 5%, which greatly reduces the production cost and has high social benefits.
