Description

Technical Field

[0001] This utility model belongs to the field of metal sheet processing and post-processing technology, and particularly relates to a drying mechanism for a phased array flaw detector for sheet metal. Background Technology

[0002] During the production of sheet metal, water stains often remain on the surface of the sheet after ultrasonic testing or cleaning. If not treated in time, these water stains will not only affect the quality of subsequent processes such as spraying and welding, but will also accelerate the oxidation of the sheet surface, leading to rust. Manual wiping is inefficient and may introduce secondary pollution.

[0003] Currently, common drying methods include natural air drying, hot air drying, or fixed air knife blowing. However, natural air drying is too time-consuming and unsuitable for continuous production lines; hot air drying is energy-intensive and prone to causing board deformation due to uneven temperature; fixed air knife blowing has limited airflow coverage, resulting in poor drying effect on board edges. Existing drying devices suffer from uneven airflow distribution, leading to water stains. Furthermore, high-pressure airflow can easily cause water splashing or board vibration. The entire device cannot flexibly adapt to boards of different widths, thicknesses, or surface conditions, resulting in a limited applicability, high energy consumption, and low drying efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problems of poor drying effect, low drying efficiency, poor adaptability and time and labor cost of existing drying devices. It provides a drying mechanism for a phased array flaw detector for sheet metal, which can quickly dry surface water stains after ultrasonic flaw detection of sheet metal, improve the quality of subsequent processing and prevent rust, and is highly efficient, environmentally friendly and widely applicable.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A drying mechanism for a phased array flaw detector for sheet metal includes a support frame spanning above a sheet metal conveyor line. The two sides of the support frame are fixed to columns on both sides of the sheet metal conveyor line. The support frame is provided with two parallel rotating air pipes, a first rotating air pipe and a second rotating air pipe. The two ends of the first rotating air pipe are connected to an automatic angle adjustment mechanism, and one end of the second rotating air pipe is connected to a manual angle adjustment mechanism. The first rotating air pipe and the second rotating air pipe are each provided with a row of adjustable nozzles to adjust the airflow angle and pressure in a timely manner according to different types of sheet metal.

[0007] Furthermore, the automatic angle adjustment mechanism includes a pair of adjusting cylinders. The adjusting cylinders are connected to the corresponding columns via cylinder mounting seats. The telescopic rods of the adjusting cylinders are vertically downward and connected to the end of the rotating air pipe through a crank mechanism, so as to adjust the rotation angle of the rotating air pipe by extending or retracting the cylinders.

[0008] Furthermore, the manual angle adjustment mechanism includes a rotating bracket, with both ends of the rotating air tube II connected to the column via the rotating bracket, and one end of the rotating air tube II extending out of the rotating bracket and connected to a rotating handle, so as to achieve angle adjustment by rotating the rotating air tube II via the handle.

[0009] Furthermore, the rotating air tubes are configured as two, which are on the same horizontal plane and respectively located on both sides of the column. The column is provided with a set of positioning holes arranged in the vertical direction, and the rotating bracket is connected with a set of positioning bolts that cooperate with the positioning holes. The rotating bracket is fixed to the column by the positioning bolts.

[0010] Furthermore, each column is equipped with an adjustment bracket at its bottom. The adjustment bracket includes a fixed platform and a set of adjustable feet connected to the bottom of the fixed platform. The bottom of the column is connected to the fixed platform to adjust the height and level of the fixed platform by adjusting the feet.

[0011] Furthermore, both the first and second rotary air tubes are connected in series with the pressure regulating module, and the air pressure inside the tubes is controlled by the pressure regulating valve, which can adjust the airflow pressure range from 0.1 to 0.7 MPa in real time.

[0012] Furthermore, the nozzles of the adjustable nozzle assembly are made of tungsten carbide and are arranged along the axial direction of the rotating air pipe. They are connected to rotating air pipe one or rotating air pipe two via a universal joint for manual adjustment of the angle of each nozzle.

[0013] Compared with the prior art, the advantages of the technical solution of this utility model are as follows:

[0014] (1) The multi-nozzle of this utility model covers the entire width, improving the drying efficiency by more than 50%;

[0015] (2) This utility model can adapt to the angle to ensure that the airflow adheres closely to the surface and the water stain removal rate is ≥99.5%;

[0025] To make this utility model clearer, the following description, in conjunction with the accompanying drawings, further illustrates a drying mechanism for a phased array flaw detector for sheet metal. The specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this utility model.

[0026] See Figure 1 , Figure 3 and Figure 4 A drying mechanism for a phased array flaw detector for sheet metal, characterized in that:

[0027] See Figure 1 , Figure 2 , Figure 5 The support frame 1 spans the top of the sheet material conveying line. The two sides of the support frame 1 are fixed to the columns 2 on both sides of the sheet material conveying line. Each column 2 has an adjustment fixing frame 9 at its bottom. The adjustment fixing frame 9 includes a fixing platform 91 and a set of adjusting feet 92 connected to the bottom of the fixing platform 91. The bottom of the column 2 is connected to the fixing platform 91 to adjust the height and level of the fixing platform by adjusting the feet.

[0028] See Figure 1 , Figure 2 and Figure 3 The support frame 1 is provided with a rotating air pipe 3 and a rotating air pipe 4 that are parallel to each other. The two ends of the rotating air pipe 3 are respectively connected to an automatic angle adjustment mechanism 5. The automatic angle adjustment mechanism 5 includes a pair of adjusting cylinders 51. The adjusting cylinders 51 are connected to the corresponding column 2 through the cylinder fixing seat 52. The telescopic rod 53 of the adjusting cylinder 51 is vertically downward and connected to the end of the rotating air pipe 3 through the crank mechanism, so as to adjust the rotation angle of the rotating air pipe 3 by the extension and retraction of the cylinder.

[0029] See Figure 1 , Figure 2 , Figure 3 and Figure 4Two rotating air tubes 4 are provided, which are on the same horizontal plane and respectively located on both sides of the column 2. One end of each rotating air tube 4 is connected to a manual angle adjustment mechanism 6. The manual angle adjustment mechanism 6 includes a rotating bracket 61. The two ends of the rotating air tube 4 are respectively connected to the column 2 through the rotating bracket 61, and one end of the rotating air tube 4 extends out of the rotating bracket 61 and is connected to a rotating handle 62, so as to adjust the angle by rotating the rotating air tube 4 through the handle.

[0030] The column 2 is provided with a set of positioning holes 21 arranged in the vertical direction, and the rotating bracket 61 is connected with a set of positioning bolts 8 that cooperate with the positioning holes 21. The rotating bracket 61 is fixed to the column 2 by the positioning bolts 8.

[0031] A row of adjustable nozzle groups 7 is provided on the first rotary air pipe 3 and the second rotary air pipe 4 respectively. The adjustable nozzle groups 7 are arranged along the axial direction of the rotary air pipe and are connected to the first rotary air pipe 3 or the second rotary air pipe 4 through a universal joint for manual adjustment of the angle of each nozzle.

[0032] Rotary air tube 3 and rotary air tube 4 are both connected in series with the pressure regulating module, and the air pressure inside the tube is controlled by the pressure regulating valve. The real-time airflow pressure range is 0.1~0.7MPa, which can be used to adjust the airflow angle and pressure in a timely manner according to different types of sheet materials.

[0033] When using it, first set the parameters: adjust the nozzle spacing to match the width of the board; then set the air pressure automatically according to the thickness of the board through the PLC; then perform dynamic drying: when the board is conveyed, the nozzles are automatically activated by photoelectric sensors; finally, perform a safety reset: the nozzles automatically stop after the operation is completed.

[0034] In this embodiment, 45 nozzles were set for a stainless steel plate that is 2 m wide and 8 mm thick, with an air pressure of 0.4 MPa. After drying, there were no water stains on the surface, and the temperature of the plate did not rise significantly.

[0035] Furthermore, the drying mechanism of this embodiment can be connected to an existing wiper device.

The nozzle material is preferably tungsten carbide, which is wear-resistant and corrosion-resistant. It can also be expanded to include an infrared sensor to detect the drying effect and realize closed-loop control.

[0036] This invention utilizes a support frame, an airflow distribution system, a pressure adjustment module, and an angle adaptation mechanism to adjust the airflow pressure in real time, enabling free adjustment of the nozzle angle. It is applicable to sheet widths of 600~4700 mm, achieving a drying efficiency of ≤3s / m. 2(Wind speed 20 m / s); Working air pressure range 0.1~0.7 MPa, automatically adjustable according to plate thickness. Compared with traditional air knives, the drying time on an 8 mm thick steel plate is reduced from 8 seconds to 3 seconds, and the water residue is reduced from 0.5 g / m². 2 Reduced to 0.02 g / m 2 The effect was remarkable.
