Description

Technical Field

[0001] This utility model belongs to the field of glass cleaning. Specifically, this utility model relates to a calibration and detection structure for an air knife of a cleaning machine. Background Technology

[0002] With the rapid development of the photovoltaic industry and the increasing scale of production, the number of cleaning machines is constantly increasing. Cleaning machines are an indispensable part of the glass processing process. After cleaning, the glass needs to be dried. During the drying process, conveyor rollers are used to transport the glass, and air knives spray air onto the glass surface for drying. The direction of the air knives directly determines the cleaning quality.

[0003] Currently, the air knives of cleaning machines are all internally designed and installed. After the cleaning machine has been running for a long time, the probability of the air knife direction changing due to glass cards is constantly increasing. If the air knife direction changes, it cannot be detected from the outside, and there is no quantitative standard, making it difficult to calibrate. This results in poor batch cleaning of products, and if the machine is stopped for maintenance and calibration, it will also cause production losses.

[0004] Utility model patent CN210532970U, published on May 15, 2020, discloses a main air knife and air knife assembly for a glass cleaning and drying machine. This main air knife for a glass cleaning and drying machine includes a main airflow chamber and a branch airflow chamber. Both the main airflow chamber and the branch airflow chamber have a structure where the airflow is gradually compressed from top to bottom. The two sides of the main airflow chamber are connected to the branch airflow chambers. The main airflow chamber includes a first top surface and a guide surface. The first top surface has an air inlet. The branch airflow chamber includes a deflection surface and a bottom surface. The bottom surface has an elongated opening. The bottom surfaces of the two branch airflow chambers are connected to form an air outlet. The deflection surface is located on both sides of the guide surface. However, this main air knife and air knife assembly for a glass cleaning and drying machine cannot solve the aforementioned technical problems. Utility Model Content

[0020] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of this invention, and to facilitate its implementation.

[0021] like Figures 1 to 3As shown, the air knife calibration and testing structure of this cleaning machine includes a side plate 1 of the machine base, a sleeve 2 on the side plate 1, and an air knife 3 including a mounting shaft 4. The end of the mounting shaft 4 is located inside the sleeve 2, and a scale 6 is fixedly connected to the end of the mounting shaft 4. A pointer 7 is fixedly connected to the end of the sleeve 2. The calibration and testing principle of the air knife 3 is as follows: When the air knife 3 deviates due to glass clips, insufficient stability, or long-term lack of maintenance, the scale 6 will also deviate. Taking the direction pointed to by the pointer 7 as the origin, the deviation can be directly confirmed by observing the direction of the pointer 7. Maintenance personnel can then adjust the scale 6 in a timely and effective manner based on the deviation. Therefore, it is not necessary to inspect from inside the cleaning machine, eliminating the need for downtime maintenance, ensuring production continuity, and facilitating the periodic maintenance of the cleaning machine and the establishment of corresponding maintenance standards in the production workshop. Therefore, it is only necessary to determine whether the air knife 3 has deviated based on the scale data on the scale 6 pointed to by the pointer 7. For a few types of cleaning machines, the pointer 7 can be directly welded to the mounting shaft 4 of the air knife 3, and the arc-shaped scale 6 can be fixed on the side plate 1 of the machine base, which can also achieve the purpose of visually inspecting the air knife 3.

[0022] like Figure 1 As shown, a nut 8 is fixedly connected to the outside of the sleeve 2, and a bolt 9 is threaded onto the nut 8. The end of the bolt 9 passes through the sleeve 2 and abuts against the mounting shaft 4. The bolt 9 controls the position of the mounting shaft 4 by cooperating with the nut 8. By abutting against the mounting shaft 4 and applying force, the bolt 9 ensures that the mounting shaft 4 is centered inside the sleeve 2, thereby ensuring that the air knife 3 is in the correct position and that the air knife 3 is level, ensuring that the drying effect of each part is uniform. The above adjustment is made by bolt 9, which is easy to control, does not have an excessive impact on the stability of the air knife 3, and has low operation requirements for maintenance personnel.

[0023] like Figure 1 As shown, a connecting plate 10 is welded to the end of the sleeve 2, and the top of the pointer 7 is riveted to the connecting plate 10, with the pointer 7 set vertically. The connecting plate 10 provides a fixed position for the pointer 7, which can also be fixed by welding or other methods. The pointer 7 is installed vertically, so that its pointing direction vertically separates the dial 6, making it easy for maintenance personnel to confirm whether the air knife 3 is offset in the positive or negative direction, and thus make timely adjustments.

[0024] like Figure 1 As shown, bolts 9 are evenly spaced along the circumference. Using multiple bolts 9 ensures that the mounting shaft 4 is subjected to uniform force, which helps maintain its long-term stability.

[0025] like Figure 1 As shown, the tip of pointer 7 has a sharp structure. This structure facilitates maintenance personnel in accurately reading the scale to confirm the offset of the air knife 3, thereby enabling them to make accurate and effective adjustments to the air knife 3.

[0026] like Figure 2As shown, a conveyor roller 11 is provided between the side plates 1 of the machine base, and the air knife 3 is inclined relative to the conveyor roller 11. The conveyor roller 11 is used to transport the cleaned glass, and the air knife 3 is an inclined air knife 3 with a larger air outlet, which shortens the glass drying time and improves the glass drying efficiency.

[0027] like Figure 2 As shown, the top cross-section of the air knife 3 is conical, and the air knife 3 has an opening 5 that extends from one end to the other. The conical design at the top of the air knife 3 can effectively gather airflow, and the opening 5 is in a straight line and evenly distributed throughout the air knife 3, which helps to improve the consistency of airflow and the consistency of the drying effect on the glass.

[0028] The maintenance procedure is as follows: Check the reading indicated by pointer 7 to confirm whether the air knife 3 has shifted. If it is confirmed that the air knife 3 requires calibration, loosen bolt 9, adjust the position of the mounting shaft 4 so that pointer 7 aligns with the set origin value on the dial 6, and then tighten bolt 9 to secure the mounting shaft 4. Simultaneously, ensure that the mounting shaft 4 is centered relative to the sleeve 2 after tightening. If this calibration and testing structure is installed at both ends of the air knife 3, perform the above operations simultaneously on both sides of the machine.

[0029] The air knife calibration and testing structure of this cleaning machine provides convenience for maintenance personnel to calibrate and test the air knife 3 through the use of pointer 7 and dial 6. The structure is simple, and timely adjustments can be made visually. The testing and maintenance operations are simple, reducing the skill requirements for employees. The adjustment accuracy of the air knife 3 is high, which is conducive to improving the glass cleaning quality. Multiple bolts 9 are also designed to fix the mounting shaft 4, which improves the convenience of the air knife 3 calibration process and the air knife 3 attitude adjustment process.

[0030] 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 non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
