[0027] The area density real-time detection device of the present application will be described in more detail below in conjunction with the schematic drawings, wherein the preferred embodiments of the present application are shown, and it should be understood that the present application described herein can be modified by those skilled in the art while still achieving the advantageous effects of the present application. Therefore, the following description should be understood as a broad knowledge for those skilled in the art, and not as a limitation of the present application.
[0028] The present application will be described in more detail below in conjunction with the drawings. The advantages and features of the present application will be more apparent according to the following description and claims. It should be noted that the drawings are very simplified and use non-precise proportions, only to facilitate, clearly assist in the purpose of illustrating the embodiments of the present application.
[0029] As shown in Figure 1 and Figure 2 The present application proposes an area density real-time detection device, comprising a signal transmitting end 1, a signal receiving end 2 and a detection conveying box 3.
[0030] Specifically, the signal transmitting end 1 is located at the side end of one side of the detection conveying box 3, and the signal transmitting end 1 is used to transmit detection light to the product to be detected.
[0031] The signal receiving end 2 is located at the side end of the other side of the detection conveying box 3, and the signal receiving end 2 is used to receive the attenuation signal of the detection light after passing through the product to be detected.
[0032] The detection conveying box 3 is used to transmit the product to be detected, and the product to be detected is in a straightened and tightened state, and the detection conveying box 3 is provided with a transmitting channel and a receiving channel on both sides, and the connecting line direction of the transmitting channel and the receiving channel is perpendicular to the thickness plane of the product to be detected.
[0033] In this embodiment, the detection device is installed on the transmission equipment of the product to be detected, and the product to be detected penetrates the detection conveying box 3. During the product conveying process, the signal transmitting end 1 transmits detection light to the product plane, and at the same time the signal receiving end 2 receives the attenuated detection light on the back of the product. According to the attenuated detection light, the area density of the product is analyzed and calculated, the area density information of the product can be quickly and accurately obtained in real time, and the coating process can be adjusted in time, so as to ensure the coating quality of the product.
[0034] The detection light is beta ray. The basic principle of beta ray detection density is to utilize the attenuation characteristics of beta ray when passing through the substance. When beta ray passes through the substance, the intensity thereof is weakened due to the interaction with atoms in the substance. The attenuation degree is negatively exponential to the density and thickness of the substance. The density of the substance can be calculated by measuring the intensity of the ray before and after passing through the substance.
[0035] In order to facilitate the product penetration, the detection conveying box 3 is provided with a maintenance door 4 which is detachably arranged on the detection conveying box 3. When the product penetration operation is performed, the maintenance door 4 can be opened to facilitate the product penetration into the detection conveying box 3.
[0036] Further, the signal transmitting end 1 comprises a transmitting box 5 and a light transmitter 6. The transmitting box 5 is fixedly arranged on the outer side wall of the detection conveying box 3, and the light transmitter 6 is arranged in the transmitting box 5. The detection light emitted by the light transmitter 6 passes through the transmitting channel.
[0037] In addition, the signal receiving end 2 comprises a receiving box 7 and a light receiver 8. The receiving box 7 is fixedly arranged on the outer side wall of the detection conveying box 3, and the light receiver 8 is arranged in the receiving box 7. The light receiver 8 is used to receive the detection light from the light transmitter 6.
[0038] Specifically, the controller 9 and the display 10 are further included. The output end of the controller 9 is connected with the light transmitter 6 and controls the light transmitter 6 to emit the detection light. The input end of the controller 9 is connected with the light receiver 8 and receives the receiving signal of the light receiver 8.
[0039] The display 10 is connected with the output end of the controller 9, and the display 10 is used to display the thickness of the product to be detected in real time.
[0040] In the embodiment, when the surface density of the product needs to be detected, the controller 9 turns on the light transmitter 6. The detection light emitted by the light transmitter 6 vertically irradiates the product plane. At the same time, the light receiver 8 located at the back of the product plane receives the attenuated detection light and converts it into an electric signal which is transmitted to the controller 9. The controller 9 analyzes and calculates the attenuation degree of the detection light and displays the calculated surface density value on the display 10. The on-site operator can observe the surface density information of the product in real time, which facilitates the adjustment of the coating process of the product, thereby improving the processing quality of the product.
[0041] It should be noted that the control of the controller 9 on the light transmitter 6, the light receiver 8 and the display 10 belongs to the prior art, and the specific circuit structure and control method thereof will not be described herein.
[0042] Further, the detection conveying box 3 is provided with an outlet 11 and an inlet 12 on the upper and lower sides respectively, and the outlet 11 and the inlet 12 are provided with elastic sealing strips 13.
[0043] Specifically, the elastic sealing strips 13 are symmetrically arranged in two, and the feeding gap between the two adjacent elastic sealing strips 13 is smaller than the thickness of the product to be detected.
[0044] In the embodiment, the product is in elastic and sliding contact with the elastic sealing strips 13 of the outlet 11 and the inlet 12 during the traction transportation, and the product between the inlet 12 and the outlet 11 is in a straightened state during the traction transportation, so as to avoid the surface density detection error caused by the relaxation and overlapping of the product, and greatly improve the accuracy of the surface density detection result.
[0045] In a specific embodiment, in order to reduce the wear between the product and the elastic sealing strip 13, the elastic sealing strip 13 is arranged in a semi-cylindrical shape.
[0046] Compared with the prior art, the utility model has at least the following beneficial effects:
[0047] The utility model utilizes the detection light to irradiate the product to be detected, and detects the thickness of the product to be detected by receiving and analyzing the attenuated detection light, so as to quickly and real-timely detect the thickness of the product to be detected, and greatly improve the detection efficiency.
[0048] Obviously, those skilled in the art can make various modifications and variations to the utility model without departing from the spirit and scope of the utility model. Therefore, if these modifications and variations of the utility model belong to the scope of the utility model claims and equivalent technologies, the utility model also intends to include these modifications and variations.
