Description

Technical Field

[0001] This utility model relates to a tempered glass production equipment, and more particularly to a surface treatment equipment for tempered glass production. Background Technology

[0002] Tempered glass and float glass are two common types of glass, differing significantly in several aspects. Tempered glass has 4-5 times higher impact resistance and bending strength than ordinary glass, enabling it to withstand greater external forces. Tempered glass also boasts better thermal stability, withstanding substantial temperature changes without easily breaking, typically withstanding temperature variations exceeding 200 degrees Celsius. Tempered glass has a higher surface hardness, making it more scratch-resistant. Furthermore, when subjected to a strong impact, tempered glass shatters into numerous small, fine fragments rather than large, sharp pieces, greatly reducing the risk of injury. Therefore, tempered glass has a wide range of applications.

[0003] The standard production steps for tempered glass are: raw glass cutting, edge grinding, cleaning and drying, tempering, inspection, and packaging. The cleaning and drying step specifically involves using a cleaning and drying machine to thoroughly clean and dry the glass. The cleaning section uses water sprayed from nozzles and brushes to clean the glass, removing surface dirt and impurities. The drying section uses air knives to quickly dry the glass, preventing residual moisture from affecting subsequent processing. Air knife drying offers high drying efficiency and excellent cleaning results; however, the air knife consumes a significant amount of power during operation, resulting in substantial energy consumption for the entire equipment. Summary of the Invention

[0004] This invention provides a surface treatment device for tempered glass production, which solves the problem of high energy consumption in the cleaning and drying process of tempered glass production in the prior art.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a surface treatment equipment for tempered glass production, comprising: a glass conveying line for continuously conveying vertical glass, including a horizontally arranged bearing bottom roller group and two vertically arranged anti-tilting roller groups, with a conveying zone formed between the two anti-tilting roller groups;

[0006] The cleaning chamber is a relatively enclosed compartment through which the glass transfer line passes.

[0007] The cleaning spray assembly is entirely housed within the cleaning chamber and includes a cleaning agent supply chamber, a first water pump, a first piping system, and several nozzles. The nozzles can spray both sides of the glass in the transfer area.

[0008] The cleaning roller assembly is located inside the cleaning chamber and behind the cleaning spray assembly. It consists of several brush rollers vertically distributed on both sides of the glass conveyor line and a motor. The motor is used to drive the brush rollers to rotate at a constant speed.

[0009] The wiping assembly is located at the rear of the cleaning chamber and includes two supports, several shafts horizontally mounted on the supports, a scraper seat mounted on the shafts, and a rubber scraper mounted on the scraper seat. The two supports are located on both sides of the glass conveying line, and the rubber scraper can wipe water off the glass in the conveying area.

[0010] The hot air assembly includes a blower, a filter, an electric heater, a duct system, and nozzles, the nozzles being located on both sides of the glass transport line behind the wiper assembly.

[0011] The glass conveyor line in this invention is used for the stable and continuous transport of glass sheets. The supporting bottom roller assembly consists of several horizontally and evenly distributed bottom rollers, all or some of which have an active rotation function. The glass sheets are placed vertically on the supporting bottom roller assembly. The anti-tilting roller assembly consists of several vertically distributed guide rollers. The spacing of the guide rollers is not uniform; it can be adjusted for suitability to facilitate subsequent cleaning operations. These guide rollers are located on both sides of the glass sheets, constraining them to remain vertical. The cleaning chamber isolates the cleaning spray assembly and the cleaning roller assembly, preventing water splashes from these two components from contaminating the rest of this invention. The cleaning spray assembly uses a first water pump to deliver cleaning agent from the cleaning agent supply chamber to the nozzles via a first piping system. These nozzles face both surfaces of the glass sheet in the transfer area. Then, a motor on the cleaning roller assembly drives the brush rollers to rotate at high speed, cleaning the surface of the glass sheet. The glass sheet exiting the cleaning chamber then passes through a squeegee assembly. The rubber blades on the squeegee assembly adhere closely to the glass sheet, efficiently removing water and minimizing residual moisture. Finally, a hot air assembly continuously blows hot air from the nozzles, effectively drying any remaining moisture on the glass sheet. A filter is installed at the air inlet of the hot air assembly to ensure that the hot air blown from the nozzles is clean, preventing secondary contamination of the glass surface.

[0012] Furthermore, this invention also includes a self-cleaning system located within the cleaning chamber. This system comprises a clean water supply chamber, a second water pump, a second piping system, and several self-cleaning nozzles. These nozzles spray the brush rollers. The self-cleaning system uses the second water pump to deliver clean water from the supply chamber to the nozzles via the second piping system. Under the spray of these nozzles, the brush rollers achieve a self-cleaning effect, preventing the accumulation of dirt on the glass slide and ensuring a good cleaning effect. Additionally, before shutdown, the self-cleaning system and the cleaning roller assembly must be started separately to perform a self-cleaning procedure on the cleaning roller assembly.

[0013] Furthermore, the support frame is inclined, and each frame has two or more rubber scrapers. The projections of adjacent rubber scrapers on the vertical plane partially overlap. The rubber scrapers are arranged in an inclined vertical array with an inclination angle between 45° and 70°. The inclined arrangement of the rubber scrapers guides the scraped wastewater to flow diagonally downwards along the inclined rubber scrapers. The partial overlap of the projections of adjacent rubber scrapers on the vertical plane ensures that the subsequent rubber scraper can remove the water stains left by the preceding rubber scraper. The segmented rubber scrapers are used to reduce the space occupied and avoid excessive spacing between the guide rollers in this area.

[0014] Furthermore, the front and rear sides of the cleaning chamber are provided with two slots for the glass to pass through. Water-retaining strips are fixed to both sides of each slot, with the two strips respectively fixed to the inner and outer sides of the slots and partially overlapping each other. The water-retaining strips are mainly used to block the slots, preventing water vapor or water droplets from splashing outwards from the cleaning chamber.

[0015] Therefore, this utility model has the following characteristics compared with the prior art: 1. This utility model uses a glass conveyor line to transport glass sheets, a cleaning spray assembly to spray the glass sheets, a cleaning roller assembly to clean the glass sheets, and a squeegee assembly to directly scrape off a large amount of adhering water on the glass sheets. Finally, a hot air assembly dries the glass sheets. Since the squeegee assembly removes most of the water, the power requirement of the hot air assembly in this utility model is significantly reduced, which can significantly improve the power consumption of the equipment and reduce power consumption.

[0024] Example 1: See Figure 1 A surface treatment device for tempered glass production includes: a glass conveyor line 100 for continuously conveying vertically positioned glass, comprising a horizontally arranged support roller group 110 and two vertically arranged anti-tilting roller groups 120, with a conveying zone 130 formed between the two anti-tilting roller groups;

[0025] The cleaning chamber is 200 cubic meters, a relatively enclosed compartment, with a glass conveyor line running through it.

[0026] See Figure 2 The cleaning spray assembly 300 is installed inside the cleaning chamber and includes a cleaning agent supply chamber 310, a first water pump 320, a first piping system 330, and several nozzles 340. The nozzles can spray both sides of the glass in the transmission area.

[0027] See Figure 6 The cleaning roller assembly 400 is located inside the cleaning chamber and behind the cleaning spray assembly. It consists of six brush rollers 410 vertically distributed on both sides of the glass conveyor line, a mounting frame 430, and a motor 420. The motor is used to drive the brush rollers to rotate at a constant speed.

[0028] The wiping assembly 500 is located at the rear of the cleaning chamber and includes two brackets 510, several shafts 520 horizontally mounted on the brackets, a scraper seat 530 mounted on the shafts, and a rubber scraper 540 mounted on the scraper seat. The two brackets are located on both sides of the glass conveying line, and the rubber scraper can wipe water off the glass in the conveying area.

[0029] See Figure 3 The hot air assembly 600 includes a blower 610, a filter 620, an electric heater 630, an air duct system 640, and nozzles 650, with the nozzles located on both sides of the glass transmission line behind the wiper assembly.

[0030] See Figure 5 In this embodiment, the glass transport line is used for stable and continuous transport of glass sheets. The supporting bottom roller group consists of several horizontally and evenly distributed bottom rollers 111. Bottom roller mounting frames 112 are mounted on both sides of the bottom rollers. All or some of the bottom rollers have an active rotation effect. The glass sheets are placed vertically on the supporting bottom roller group. The anti-tilting roller group consists of several vertically distributed guide rollers 121. Guide roller mounting frames 122 are mounted at both ends of the guide rollers. The spacing of the guide rollers is not uniform; it can be adjusted for suitability to facilitate subsequent cleaning operations. These guide rollers are located on both sides of the glass sheets, serving to constrain the glass sheets to remain vertical. The cleaning chamber isolates the cleaning spray assembly and the cleaning roller group, preventing these... The water spray generated by the operation of the two sets of components contaminates other areas and the glass sheet in this embodiment. The cleaning spray assembly uses a first water pump to deliver cleaning agent from the cleaning agent supply chamber to the nozzles via a first piping system. These nozzles are positioned directly over the two surfaces of the glass sheet in the transfer area. Then, the motor on the cleaning roller assembly drives the brush rollers to rotate at high speed, using the brush rollers to clean the surface of the glass sheet. The glass sheet output from the cleaning chamber then passes through a squeegee assembly. The rubber blades on the squeegee assembly adhere closely to the glass sheet, efficiently removing accumulated water from the glass surface, leaving very little residual moisture. Then, the hot air assembly continuously blows hot air from the nozzles, which efficiently dries any remaining moisture on the glass sheet. The air inlet of the hot air assembly is equipped with a filter, thus ensuring that the hot air blown from the nozzles is clean and preventing secondary contamination of the glass surface.

[0031] See Figure 2 This embodiment also includes a self-cleaning system 700, located within the cleaning chamber. This system includes a clean water supply chamber 710, a second water pump 720, a second piping system 730, and several self-cleaning nozzles 740. The self-cleaning nozzles spray the brush rollers. The self-cleaning system uses the second water pump to deliver clean water from the clean water supply chamber to the self-cleaning nozzles via the second piping system. Under the spray of these nozzles, the brush rollers achieve a self-cleaning effect, preventing the accumulation of dirt on the glass slides and ensuring a good cleaning effect. Furthermore, before shutdown, this embodiment requires a separate start-up of the self-cleaning system and the cleaning roller assembly to perform a self-cleaning procedure on the cleaning roller assembly.

[0032] See Figure 4The support frame is angled, with two or more rubber scrapers on each frame. The projections of adjacent rubber scrapers on the vertical plane partially overlap. The rubber scrapers are arranged in an angled vertical array at 60°. The angled arrangement of the rubber scrapers guides the scraped wastewater to flow downwards along the inclined rubber scrapers. The partial overlap of the projections of adjacent rubber scrapers on the vertical plane ensures that the subsequent rubber scraper can remove water stains left by the preceding rubber scraper. The segmented rubber scrapers are used to reduce the space occupied and avoid excessive spacing between the guide rollers in that area.

[0033] See Figure 1 Two positioning nuts 521 are screwed onto the shaft and located on both sides of the bracket. The position of the water-blocking rubber strip can be finely adjusted by adjusting the position of the two positioning nuts.

[0034] See Figure 1 The cleaning chamber has two slots 210 on its front and rear sides for the glass to pass through. Water-retaining strips 220 are fixed to both sides of the slots, with the two water-retaining strips fixed to the inner and outer sides of the slots respectively and partially overlapping each other. The water-retaining strips are mainly used to block the slots and prevent water vapor or water droplets from splashing out of the cleaning chamber from the slots.

[0035] See Figure 4 The wiper assembly also includes a wastewater collection tank 550 located at the bottom for collecting the wiped-off wastewater.

[0036] This invention can be modified in many ways, as will be apparent to those skilled in the art, and such modifications are not considered to depart from the scope of this invention. All such modifications that are obvious to those skilled in the art are included within the scope of these claims.
