Description

Technical Field

[0001] This utility model belongs to the field of glass production technology, and more specifically, it relates to a wet spray structure for glass cleaning machine. Background Technology

[0002] In the field of glass manufacturing technology, there is a need for cleaning glass using wet scrubbing machines with chemical spraying. Existing wet scrubbing machines use a traditional top-spray structure, where multiple nozzles are mounted on a spray pipe. During spraying, problems arise such as nozzle clogging leading to no spray, uneven spraying, and nozzle breakage due to chemical corrosion. Addressing these issues significantly impacts manpower and safety. This not only affects production efficiency but also reduces product yield due to poor spraying.

[0003] Existing technology includes a device titled "A Cleaning Apparatus for Glass Substrates" with publication number CN213856172U. This device comprises a roller conveyor belt and a first U-shaped support frame and a second U-shaped support frame fixedly installed at the front and rear ends of the roller conveyor belt. A glass substrate is tightly mounted above the roller conveyor belt. The first U-shaped support frame includes a horizontal plate and a first vertical plate and a second vertical plate vertically installed at the left and right ends of the bottom surface of the horizontal plate. This invention, through the arrangement of the first and second cleaning mechanisms, can simultaneously clean both ends of the glass substrate, avoiding quality fluctuations caused by detergent residue on the glass substrate. The distance between the nozzle and the glass substrate can be adjusted, making it suitable for practical use. The water-blocking mechanism prevents moisture from entering without damaging the glass surface. The liquid cutting mechanism, consisting of two cutters, allows for the introduction of clean air, effectively blowing away any moisture containing the detergent from the glass substrate. The prior art includes a technology entitled "An Ultra-Fine Cleaning Process for Thin Mobile Phone Glass" with publication (announcement) number "CN112387733A". This technology discloses an ultra-fine cleaning process for thin mobile phone glass. The cleaning equipment used includes a frame, a feeding conveyor mechanism, a dust removal air knife area, a brush washing area, a two-fluid spray area, a DI water spray area, a water-cutting air knife area, and a discharge conveyor mechanism. The feeding conveyor mechanism passes sequentially through the dust removal air knife area, the brush washing area, the two-fluid spray area, the DI water spray area, and the water-cutting air knife area on the frame. The brush washing area includes a brush rotation unit, a chemical spraying unit, and a circulating water spraying unit. This invention employs a method of brushing with a chemical solution followed by spray cleaning, which has stronger cleaning power and a wider cleaning range, meeting the needs of cleaning thin mobile phone glass of various sizes; the use of two fluids and DI water rinsing can effectively wash away dirt on thin mobile phone glass; and the use of air knives to blow away dust and residual moisture on thin mobile phone glass provides a good blowing effect, ensuring good surface cleanliness of the product.

[0004] However, this technology does not address the technical issues and solutions of this application. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a simple structure for a wet spraying machine for glass cleaning that ensures uniform liquid output from the waterfall sprayer, avoids clogging and uneven liquid flow, and improves production efficiency and yield, in order to address the shortcomings of the existing technology.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] This utility model relates to a wet spray structure for glass cleaning. Multiple waterfall blades are arranged above the glass conveying roller group. Each waterfall blade has a spray opening at the front and top. Each waterfall blade is connected to a liquid supply pipe. The width of the overflow opening of the waterfall blade is larger than the width of the glass to be cleaned.

[0008] The glass conveying roller assembly includes multiple guide rollers arranged at intervals.

[0009] The glass conveying roller assembly has multiple waterfall blades arranged at intervals above it. The multiple waterfall blades are arranged in parallel horizontally and in parallel vertically to the guide rollers.

[0010] The waterfall medicine knife has a cavity structure. A bottom horizontal plate is set on the lower front side of the waterfall medicine knife, and the opening above the bottom horizontal plate is an overflow opening.

[0011] The liquid supply pipeline includes multiple liquid supply branch pipelines and a liquid supply main pipeline. Each waterfall medicine knife is connected to a liquid supply branch pipeline, and each liquid supply branch pipeline is connected to a liquid supply main pipeline. A liquid supply pump is installed on the liquid supply main pipeline.

[0012] The multiple guide rollers of the glass conveying roller assembly are located at the same height.

[0013] A flow control valve is installed on the main liquid supply pipeline near the branch liquid supply pipeline, or a flow control valve is installed on each branch liquid supply pipeline.

[0014] The glass conveying roller assembly has multiple guide rollers arranged in parallel.

[0015] The main liquid supply pipeline is connected to the liquid storage tank.

[0016] The working principle and beneficial effects of this utility model are as follows:

[0017] The wet-type spray structure for glass cleaning described in this utility model uses a glass conveying roller assembly to transport the glass. Instead of spray pipes and nozzles, multiple waterfall-style cleaning blades are installed above the glass conveying roller assembly. Each waterfall-style cleaning blade has a hollow structure with an internal supply of cleaning solution. Each waterfall-style cleaning blade has a spray opening at its front top, and each blade is connected to a supply pipe. The cleaning solution is continuously supplied to the waterfall-style cleaning blades, overflowing from the spray openings and forming a waterfall-like overflow that cleans the glass below. Multiple waterfall-style cleaning blades can be installed at intervals, and they can be partially or fully opened to meet the cleaning needs of glass of different lengths. The width of the overflow opening of the waterfall-style cleaning blade is larger than the width of the glass to be cleaned, resulting in a cleaning surface width that is larger than the glass width, effectively covering the glass and ensuring a good cleaning effect.

[0022] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part:

[0023] As attached Figure 1 Appendix Figure 2As shown, this utility model is a wet spray structure for glass cleaning. Multiple waterfall-style cleaning blades 4 are arranged above the glass conveying roller assembly. Each waterfall-style cleaning blade 4 has a spray opening 6 at its front upper part. Each waterfall-style cleaning blade 4 is connected to a liquid supply pipe. The width of the overflow opening 6 of the waterfall-style cleaning blade 4 is larger than the width of the glass 1 to be cleaned. This structure addresses the shortcomings of existing technologies by proposing an improved technical solution. In this structure, a glass conveying roller assembly is used to transport the glass. The spray pipe and nozzles are eliminated; instead, multiple waterfall-style cleaning blades 4 are arranged above the glass conveying roller assembly. Each waterfall-style cleaning blade 4 has a hollow structure that can supply cleaning solution internally. Each waterfall-style cleaning blade 4 has a spray opening 6 at its front upper part, and each waterfall-style cleaning blade 4 is connected to a liquid supply pipe. The liquid is continuously supplied to the waterfall-style cleaning blades 4, and the liquid continuously overflows from the spray opening 6, forming a waterfall-like overflow liquid that cleans the glass below. Multiple waterfall cleaning blades 4 can be installed at intervals, and these blades can be partially or fully opened to meet the cleaning needs of glass of different lengths. The width of the overflow opening 6 of the waterfall cleaning blade 4 is larger than the width of the glass 1 to be cleaned, resulting in a cleaning surface width of the overflow liquid that is larger than the width of the glass, effectively covering the glass and ensuring a good cleaning effect. The wet spray structure for glass cleaning described in this invention is simple in structure, ensures uniform liquid output from the waterfall cleaning blades, avoids clogging and uneven liquid flow, and improves production efficiency and yield.

[0024] The glass conveying roller assembly includes multiple guide rollers 2 arranged at intervals. These guide rollers 2 are located at the same height and are arranged in parallel. In this structure, each guide roller 2 includes a drive roller and a driven roller, and the multiple guide rollers 2 rotate in the same direction and at the same speed, ensuring reliable conveying of the glass 1 to be cleaned. During the conveying process on the guide rollers 1, the glass 1 is cleaned with a cleaning solution below the waterfall cleaning knife 4.

[0025] Multiple waterfall-style cleaning blades 4 are arranged at intervals above the glass conveying roller assembly. These blades are horizontally parallel and vertically parallel to the guide rollers 2. With this structure, the distances between the multiple waterfall-style cleaning blades 4 and the guide rollers are equal, resulting in equal distances between the blades 4 and the glass, allowing cleaning to be completed during the glass conveying process.

[0026] The waterfall medicine knife 4 has a cavity structure. A bottom horizontal plate 7 is provided on the lower front side of the waterfall medicine knife 4, and the opening above the bottom horizontal plate 7 is an overflow opening 6. In the above structure, the upper part of the bottom horizontal plate is a straight structure, and an opening is formed at the upper front part of the waterfall medicine knife to realize overflow.

[0027] The liquid supply pipeline includes multiple branch supply pipelines 9 and a main supply pipeline 8. Each waterfall knife 4 is connected to a branch supply pipeline 9, and each branch supply pipeline 9 is connected to the main supply pipeline 8. A liquid supply pump 11 is installed on the main supply pipeline 8. In this structure, the main supply pipeline 8 is used for supplying the liquid medicine, and each branch supply pipeline 9 is used to supply the liquid medicine to the corresponding waterfall knife 4.

[0028] A flow control valve 10 is installed on the main supply pipeline 8 near the branch supply pipeline 9. In this structure, the flow control valve controls the total amount of liquid, and since the different supply branch pipelines have the same diameter, the amount of liquid supplied is basically the same. Alternatively, the flow control valve 10 is not installed on the main supply pipeline 8, but rather one flow control valve 10 is installed on each supply branch pipeline 9 to control the amount of liquid.

[0029] The main supply pipeline 8 is connected to the storage tank 3. In this structure, the storage tank 3 stores the cleaning solution, supplying the solution when the supply pump and flow control valve 10 are open, and stopping the supply when the supply pump and flow control valve 10 are closed, thus meeting actual needs.

[0030] The wet spray structure for glass cleaning described in this utility model features a glass conveying roller assembly for transporting the glass. Instead of spray pipes and nozzles, multiple waterfall-style cleaning blades 4 are positioned above the glass conveying roller assembly. Each waterfall-style cleaning blade 4 has a hollow cavity structure that can supply cleaning solution. A spray opening 6 is located above the front of each waterfall-style cleaning blade 4, and each waterfall-style cleaning blade 4 is connected to a liquid supply pipe. The solution is continuously supplied to the waterfall-style cleaning blades 4, overflowing from the spray opening 6 and forming a waterfall-like overflow liquid that cleans the glass below. Multiple waterfall-style cleaning blades 4 can be spaced apart and can be partially or fully opened to meet the cleaning needs of glass of different lengths. The width of the overflow opening 6 of the waterfall-style cleaning blade 4 is larger than the width of the glass to be cleaned 1, resulting in a cleaning surface 5 wider than the glass width, effectively covering the glass and ensuring a good cleaning effect.

[0031] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
