Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of coating and washing machines, and in particular to an automatic spraying system for coating and washing machines. Background Technology
[0002] The first spray system of the coating and washing machine mainly utilizes an internal water tank circulation system. The tank is first filled with pure water, which is then pumped into the spray pipes and sprayed onto the glass to clean surface glass powder. While internal water circulation helps save water, the circulating pure water is quickly contaminated by glass powder. The pure water sprayed from the spray pipes contains glass powder, which can easily lead to incomplete cleaning of the glass surface, resulting in abnormal glass quality. Furthermore, the pure water in the tank needs to be replaced periodically, impacting production efficiency. Summary of the Invention
[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides an automatic spraying system for a coating glass washing machine, which ensures the cleaning quality of the coating glass washing machine and the quality of the coated glass, while reducing water consumption.
[0004] Technical Solution: To achieve the above objectives, this utility model provides an automatic spraying system for a coating and washing machine, comprising a spraying module and a sensing module. The water inlet of the spraying module is connected to a water supply pipe via a main control valve. The sensing module is located at the glass inlet of the coating and washing machine. The sensing signal output of the sensing module is electrically connected to the control signal receiving end of the main control valve via a control module. The sensing module is used to sense the entry of the glass sheet, and the control module is used to control the main control valve to open when it receives the sensing signal of the glass sheet entering.
[0005] Furthermore, the spray module includes several spray units, which are arranged at equal intervals with their arrangement direction perpendicular to the glass sheet entry direction. Each spray unit is equipped with a single-control valve. The sensing signal output terminal of the sensing module is electrically connected to the control signal receiving terminals of the multiple single-control valves through the control module. The sensing module is used to detect the width change of the glass sheet in the arrangement direction of the spray unit when the glass sheet enters. The control module is used to control the opening and closing of the multiple spray units according to the received width change sensing signal.
[0006] Furthermore, the sensing module includes a bracket, on which a main control sensing unit and multiple individual control sensing units are disposed. The main control sensing unit and multiple individual control sensing units are arranged along the arrangement direction of the multiple spray units. The main control sensing unit is electrically connected to the main control valve through the control module, and the multiple individual control sensing units are electrically connected to the multiple individual control valves through the control module.
[0007] Furthermore, the main control sensing unit is located on the central axis of the wafer feeding direction of the coating and washing machine, and the multiple single control sensing units are respectively located on both sides of the main control sensing unit.
[0008] Furthermore, the main control sensing unit and the multiple single control sensing units are all fixedly arranged, and the same number of single control sensing units are symmetrically arranged on both sides of the main control sensing unit. The main control sensing unit and the multiple single control sensing units are arranged at equal intervals.
[0009] Furthermore, the main control sensing unit is fixedly installed, and a single control sensing unit is slidably installed on each side of the main control sensing unit. The sliding direction is collinear with the arrangement direction of the three units. The single control sensing unit is electrically connected to the walking control unit of the sliding mechanism to which it is located. A distance measuring sensing module is provided on the side of each of the two single control sensing units closest to the main control sensing unit. The two distance measuring sensing modules are electrically connected to the multiple single control valves through the control module.
[0010] Beneficial Effects: This utility model discloses an automatic spray system for a coating glass washer. The spray module is directly connected to a pure water supply pipe to ensure that pure water is always used for cleaning, thereby achieving optimal cleaning quality and avoiding the impact of unwashed glass powder on glass quality. The system controls the start and stop of the spray by sensing whether a glass sheet enters the coating glass washer, spraying only when a glass sheet enters, effectively reducing water consumption. Furthermore, the system senses the shape and orientation of the glass entering the washer, selectively controlling the spray area to ensure that the glass sheet is completely covered and thoroughly cleaned while closing unnecessary spray nozzles, minimizing the total water output and further reducing water consumption. Overall, this system ensures the cleaning quality of the coating glass washer and the quality of the coated glass, while minimizing water consumption. Attached Figure Description
[0011] Figure 1 This is a schematic diagram of the overall structure of a coating and washing machine with glass inlet end face, according to an embodiment of the present invention. Detailed Implementation
[0012] The present invention will be further described below with reference to the accompanying drawings.
[0013] As attached Figure 1The automatic spray system for a coating and washing machine includes a spray module 1 and a sensing module 2. The water inlet of the spray module 1 is connected to a water supply pipe 4 via a main control valve 3. The sensing module 2 is located at the glass inlet of the coating and washing machine 8. The sensing signal output of the sensing module 2 is electrically connected to the control signal receiving end of the main control valve 3 via a control module. The sensing module 2 is used to sense the entry of the glass sheet 6. The control module is used to control the main control valve 3 to open when it receives the sensing signal of the glass sheet entering. By directly connecting the first spray pipe of the coating washing machine to the pure water supply pipe, the spray is controlled by the main control valve 3. The main control valve adopts a solenoid valve structure, and the sensing module 2 uses one or more photoelectric switches. The photoelectric switches are set at the inlet of the coating washing machine 8. When the photoelectric switch senses the glass entering, it transmits a sensing signal to control the main control solenoid valve to open and start spraying. After the glass sheet has completely passed through, when the photoelectric switch no longer senses the glass sheet, it controls the main control solenoid valve to close and end the spraying. In this way, spraying and cleaning are only performed when a glass sheet passes through the first spray pipe, and the machine is closed at other times, which effectively reduces water consumption. At the same time, pure water is always sprayed, which can effectively ensure the cleaning quality and thus ensure the quality of the coated glass. The contaminated water containing glass powder after cleaning is collected by the equipment's own water collection tank 7 and discharged in a timely manner, eliminating the need for frequent shutdowns for cleaning and reducing the impact on production efficiency.
[0014] The spray module 1 includes several spray units 11, which are arranged at equal intervals and perpendicular to the direction in which the glass sheet 6 enters. Each spray unit 11 is equipped with a single-control valve. The sensing signal output terminal of the sensing module 2 is electrically connected to the control signal receiving terminals of the multiple single-control valves through the control module. The sensing module 2 is used to detect the width change of the glass sheet 6 in the arrangement direction of the spray units 11 when the glass sheet enters. The control module is used to control the opening and closing of the multiple spray units 11 according to the received width change sensing signal. Normally, glass plates are mostly rectangular, but they may also be irregularly shaped. Or, when the glass plate is fed in, it may not be placed completely upright, or the size of the glass plate being cleaned may be small. This can cause the pure water sprayed out to not fully act on the glass plate, but water consumption is still generated. Therefore, the sensing module can roughly sense the relative position change of the glass plate as it passes under the spray pipe, thereby accurately and in real time controlling the spray area and shutting down the spray unit 11 that is not actually cleaning, thus minimizing water consumption.
[0015] The sensing module 2 includes a bracket 21, on which a main control sensing unit 22 and multiple individual control sensing units 23 are mounted. The main control sensing unit 22 and the multiple individual control sensing units 23 are arranged along the arrangement direction of the multiple spray units 11. The main control sensing unit 22 is electrically connected to the main control valve 3 through the control module, and the multiple individual control sensing units 23 are electrically connected to the multiple individual control valves through the control module. Figure 1 As shown, the support frame is horizontally mounted above the roller assembly 5 of the coating washer. The roller assembly 5 is used to receive and transport glass sheets into the coating washer. Below the roller assembly 5 is a water collection tank 7. The main control sensing unit 22 is located on the central axis of the coating washer 8 in the direction of sheet feeding, and multiple single-control sensing units 23 are located on both sides of the main control sensing unit 22.
[0016] The main control sensing unit 22 is preferably fixedly installed in the middle area of the bracket 21. There may be one or more units, with multiple units ensuring normal operation even if individual units are damaged. Since glass sheets of any size or shape are typically placed centered on the roller group 5 during feeding, automated equipment may be more precise. While manual feeding may not be perfectly centered, it won't deviate too much. Therefore, centering the main control sensing unit allows it to prioritize sensing the entry of the glass sheet, thus prioritizing the opening of the main control valve. Furthermore, the sensing results from multiple individual control sensing units 23 are used to selectively open localized spray units, achieving precise coverage cleaning.
[0017] In a preferred embodiment, the main control sensing unit 22 and multiple individual control sensing units 23 are fixedly arranged. The same number of individual control sensing units 23 are symmetrically arranged on both sides of the main control sensing unit 22, and the main control sensing unit 22 and multiple individual control sensing units 23 are arranged at equal intervals. Each main control sensing unit 22 and multiple individual control sensing units 23 uses a consistent photoelectric switch. The multiple photoelectric switches are arranged at equal intervals, with each photoelectric switch corresponding one-to-one or one-to-many to multiple spray units 11. One or more photoelectric switches located in the middle position serve as the main control sensing unit. When one or more photoelectric switches in the middle position sense the glass entering, they simultaneously open the main control solenoid valve and its corresponding individual control solenoid valve. Then, other photoelectric switches on both sides that can sense the glass sheet open their corresponding individual control solenoid valves. This achieves precise control of the spray range.
[0018] In another preferred embodiment, the main control sensing unit 22 is fixedly installed, and a single-control sensing unit 23 is slidably installed on each side of the main control sensing unit 22, with the sliding direction collinear with the arrangement direction of the three units. The single-control sensing unit 23 is electrically connected to the walking control unit of the sliding mechanism to which it is located. A distance measuring sensing module is installed on the side of each of the two single-control sensing units 23 closest to the main control sensing unit 22. The two distance measuring sensing modules are electrically connected to multiple single-control valves through the control module. Similarly, photoelectric switches are used. One or more fixed photoelectric switches in the middle control the opening and closing of the main solenoid valve. When the fixed photoelectric switch senses the entry of glass, the movable photoelectric switches on both sides move outward until they sense the edge of the glass sheet if they sense it, and inward until they sense the edge of the glass sheet if they do not sense it. This lateral adjustment ensures that the movable photoelectric switches on both sides are always near the edge of the glass sheet. Based on this, and according to the distance feedback from the two distance measuring sensing modules, the spray units within the corresponding length range are selectively opened. This allows for precise spray range control using fewer sensors.
[0019] The above are merely preferred embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
