[0030] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. The described embodiment is a contact part embodiment of the utility model, not all embodiments.

[0031] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0032] Example 1

[0033] Please refer to the attached Figure 1-4The present embodiment provides an oven valve opening detection device, which is used to control the opening of the air valve 310 inside the oven and detect the opening of the air valve 310, adjust the air flow, thereby controlling the temperature inside the oven and improving the stability of the oven. The oven air valve 310 is usually composed of a valve body, a valve disc, a valve stem, etc. Its working principle is based on the principles of fluid mechanics and elasticity. When the air valve 310 is in a closed state, a sealed gap is formed between the valve disc and the valve seat to prevent gas from passing through. When the air flow needs to be adjusted, the gap between the valve disc and the valve seat is gradually increased or decreased by rotating the valve stem, thereby achieving the purpose of adjusting the air flow. Because it is a prior art, the specific structure of the air valve 310 is not introduced in detail in this embodiment.

[0034] The valve assembly 3 includes a first connecting rod 1, a second connecting rod 2, a valve assembly 3, a coupling 4 and an angle sensor 5. The valve assembly 3 includes a wind valve 310 and a fixing frame 320. The wind valve 310 is movably arranged on the fixing frame 320. The wind valve 310 can rotate relative to the fixing frame 320. The number of wind valves 310 can be multiple, and this embodiment does not limit this. For example, when using, please refer to Figure 1 When the air valve 310 is closed relative to the fixing frame 320, the air flow is blocked. When the air valve 310 rotates relative to the fixing clamp, the air flow passes through the gap between the air valve 310 and the fixing frame 320.

[0035] The first connecting rod 1 is connected to one end of the second connecting rod 2 in a transmission manner to drive the second connecting rod 2 to rotate, and the other end of the second connecting rod 2 is connected to the air valve 310 to drive the air valve 310 to rotate relative to the fixed frame 320. Specifically, the first connecting rod 1 is vertically arranged, and the first connecting rod 1 and the second connecting rod 2 are arranged in a transmission manner. The first connecting rod 1 and the second connecting rod 2 can be arranged by setting a rotating joint, a gear rack, etc., so that when the first connecting rod 1 rotates, the second connecting rod 2 is driven to rotate, thereby driving the air valve 310 to rotate relative to the fixed frame 320 to control the opening of the air valve 310. The angle sensor 5 is arranged on the first connecting rod 1 or the second connecting rod 2 through the coupling 4 to detect the rotation angle of the air valve 310. Among them, the angle sensor 5 can be arranged on the first connecting rod 1 or the second connecting rod 2, and it can detect the rotation angle of the first connecting rod 1 and the second connecting rod 2. The angle sensor 5 can be a rotation angle sensor 5, a potentiometer, a rotary transformer, etc. Preferably, when the coupling 4 is set, its rigidity should not be too high to prevent it from damaging the angle sensor 5 .

[0036] By setting the first connecting rod 1 and the second connecting rod 2, the opening of the air valve 310 can be controlled. At the same time, an angle sensor 5 is set on the first connecting rod 1 or the second connecting rod 2 to detect its rotation angle, thereby inferring the rotation angle of the air valve 310, monitoring the opening of the air valve 310, adjusting the air intake inside the oven, and adjusting the temperature inside the oven. The collected data is fed back, and the function of early warning of the opening of the oven valve can be realized in the rapid changeover of the coating machine and the conventional process production, thereby improving the product yield; compared with the existing mechanical and manual detection method, its detection accuracy is high and the response is fast, and it can achieve accurate feedback and control, which is conducive to improving product quality.

[0037] Furthermore, the angle sensor 5 is a potentiometer. When in use, when the potentiometer rotates with the first connecting rod 1 or the second connecting rod 2, its output end can obtain a resistance value or voltage proportional to the rotation angle, and detect the rotation angle of the first connecting rod 1 or the second connecting rod 2.

[0038] In some embodiments, the lowest temperature that the potentiometer can withstand is greater than 65° C. This prevents the potentiometer from being damaged due to high regional temperature during the production process.

[0039] In some embodiments, the range of the potentiometer is greater than the rotation angle of the air valve 310. Preferably, the range of the potentiometer is 360 degrees, and the rotation angle is fully detected. If the use angle of the potentiometer is less than 360 degrees, its range should be greater than the rotation angle of the air valve 310 to ensure that the detection range covers the full range and does not damage the potentiometer.

[0040] In some embodiments, a driving member is further included, and the driving member is in transmission connection with the first connecting rod 1 to drive the first connecting rod 1 to rotate. The driving member is used to drive the first connecting rod 1 to rotate. By setting the driving member, the rotation of the first connecting rod 1 can be made simpler and more convenient. The driving member can be an adjustment handle, a motor, a steering gear, etc., which is not limited in this embodiment. Exemplarily, the driving member is an adjustment handle, which is arranged at the end of the first connecting rod 1 facing away from the second connecting rod 2, and the first connecting rod 1 is driven to rotate by rotating the adjustment handle.

[0041] In some embodiments, the end of the first connecting rod 1 and the end of the second connecting rod 2 are meshed through gears, so that the first connecting rod 1 drives the second connecting rod 2 to rotate. By setting gears, the relative rotation angle and speed between the first connecting rod 1 and the second connecting rod 2 can be accurately controlled, thereby improving the accuracy of control.

[0042] Preferably, one end of the second connecting rod 2 facing away from the air valve 310 is connected to one end of the coupling 4, and the other end of the coupling 4 is connected to the potentiometer. The potentiometer is arranged on the second connecting rod 2 through the coupling 4, and compared with being arranged on the first connecting rod 1, being arranged on the second connecting rod 2 can more accurately detect the rotation angle of the air valve 310.

[0043] For example, Figure 1-2 As shown, the oven valve opening detection device also includes a connecting rod fixing shell and a potentiometer fixing shell, and the first connecting rod 1 and the second connecting rod 2 are fixedly arranged through the connecting rod fixing shell, and the gears are meshed at the same time. The end of the second connecting rod 2 is connected with a coupling 4, and then the potentiometer fixing shell is sleeved on the connecting rod fixing shell, and the potentiometer is connected to the other end of the coupling 4. When the first connecting rod 1 rotates to a fixed position, the potentiometer rotates to a corresponding position, and at this time, the opening angle of the air valve 310 corresponds to the potentiometer angle.

[0044] In some embodiments, the fixing frame 320 is provided with a first rotating rod 321, a second rotating rod 322 and a transmission rod 323, the two ends of the transmission rod 323 are respectively movably connected with the first rotating rod 321 and the second rotating rod 322, and the second connecting rod 2 is connected with the first rotating rod 321. There are two air valves 310, which are respectively arranged on the first rotating rod 321 and the second rotating rod 322, the first rotating rod 321 is hinged with the transmission rod 323, and the second rotating rod 322 is hinged with the transmission rod 323. When the second connecting rod 2 drives the first rotating rod 321 to rotate, the second rotating rod 322 is driven to rotate through the transmission rod 323, and the two air valves 310 can be controlled to open and close at one time, and the air valves 310 are adjustable in the range of vertical blocking and horizontal full opening.

[0045] Example 2

[0046] Embodiment 2 provides a system for detecting the opening of an oven valve, such as Figure 5-6 As shown, it includes an oven valve opening device, an input module, a PLC module and a touch screen, the input module is connected to the potentiometer, the PLC module is connected to the input module, and the touch screen is connected to the PLC module. Specifically, it also includes a DC power supply, the signal of the potentiometer adopts a 12V power supply, and the power supply, each module and the potentiometer wiring use a shielded national standard signal cable. Exemplarily, during use, the PLC module A301 can recognize that the signal is a 0-10V voltage signal, and the input voltage signal 12V and 0V of the 12V DC power supply A101 are respectively connected to the B1 and B3 ports of the potentiometer A201; the B2 and B3 signals of the potentiometer A201 are output to the input module A202. When the first connecting rod of the potentiometer A201 rotates, the angle changes, and then the voltage between B2 and B3 changes. The PLC module A301 reads the value of the input module A202 and feeds the monitoring back to the touch screen A401.

[0047] In the daily production of the coating machine, the oven valves at different positions in different ovens are collected in real time through the potentiometer A201 and processed in the PLC module A301. The normal opening of the corresponding process can be compared with the opening value collected in real time. When an abnormal deviation occurs, the manual valve of the air valve does not match the current process, and an alarm prompt is given on the touch screen A401. This system can feedback and warn the signal of the potentiometer, with a fast response speed, improving product yield.
