[0051] The weighing module 3 is disposed at one end where the base 1 is connected to the cover 2 and is electrically connected to the processing control unit.

[0052] Among them, the weighing module 3 is used to collect the weight information of the trademark paper and output the weight information of the trademark paper to the processing control unit. The weighing module 3 can adopt the weighing component of the electronic scale sold on the market, and in order to improve the detection accuracy, the accuracy of the weighing module 3 is at least accurate to the percentile.

[0053] The image acquisition module includes a CCD camera 5 and an image acquisition card. The CCD camera 5 is fixedly connected to the top inner wall of the cover body 2. The central axis of the CCD camera 5 coincides with the central axis of the weighing module 3. The CCD camera 5 is electrically connected to the image acquisition card and the power supply. The image acquisition card is electrically connected to the processing control unit.

[0054] Among them, the power supply provides the required electric energy for the CCD camera 5, and the CCD camera 5 and the image acquisition card can be connected through the Cameralink serial port. The CCD camera 5 is used to take photos of the trademark paper and transmit the photos to the image acquisition card for processing. The image acquisition card outputs the processed photo information to the processing control unit, and the processing control unit identifies and calculates the processed photo information to obtain the area information of the trademark paper. In order to improve the imaging effect of the CCD camera 5, the cover body 2 is set as a light-shielding cover body to prevent external light from affecting the imaging effect.

[0055] The intelligent interactive display screen 4 is embedded in one side of the base 1, and is electrically connected to the processing control unit and the power supply. Several light sources 6 are fixedly connected to the top inner wall of the cover body 2, and several light sources 6 are evenly distributed in a ring shape on the outer peripheral side of the CCD camera 5. The central axes of several light sources 6, the central axis of the CCD camera 5 and the central axis of the weighing module 3 are collinear, and the light source 6 is electrically connected to the processing control unit.

[0056] Among them, the power supply provides the required electric energy for the smart interactive display screen 4, and the smart interactive display screen 4 is embedded in the inclined side of the base 1. The smart interactive display screen 4 can obtain the weight information, area information and gram weight information of the trademark paper from the processing control unit for the staff to know. The staff can operate the detection device involved in the embodiment of the present application through the smart interactive display screen 4. The smart interactive display screen 4 includes at least touch buttons for weight collection, area collection and turning on the light source 6, and displays the collected weight information, area information and calculated gram weight information. In order to improve the imaging effect of the CCD camera 5, several of the light sources 6 and the CCD camera 5 are coaxially arranged to provide uniform lighting.

[0057] At least three of the legs 19 are fixedly connected to the bottom end of the base 1 , and a rubber buffer pad 20 is provided at one end of the leg 19 away from the base 1 , and the rubber buffer pad 20 is threadedly matched with the leg 19 .

[0058] Among them, a plane is determined according to three points, and the number of the legs 19 is at least three. In the present embodiment, in order to improve stability, the number of the legs 19 is four, which are respectively arranged at the four corners of the bottom end of the base 1. Because the weighing module 3 is a precision instrument, the influence of external vibration on the device can be effectively avoided by arranging the rubber buffer pad 20. By arranging the rubber buffer pad 20 to be threadedly matched with the legs 19, the horizontality of the device can be ensured by adjusting the four rubber buffer pads 20, thereby improving the accuracy of the device in detecting the weight information of the trademark paper.

[0059] The alarm buzzer is disposed inside the base 1 , and the alarm buzzer is electrically connected to the processing control unit.

[0060] Specifically, when the grammage information of the trademark paper calculated by the processing control unit does not meet the standard, the alarm buzzer sends out an alarm message to prompt the staff.

[0061] Next, the working principle of the embodiment is described in detail to enable those skilled in the art to better understand the present invention:

[0062] The staff puts the trademark paper on the weighing module 3, closes the sliding door 10, turns on the light source 6 through the intelligent interactive display screen 4, collects the weight information and area information of the trademark paper, and the processing control unit calculates the gram weight information of the trademark paper based on the weight information and area information of the trademark paper, opens the sliding door 10, takes out the trademark paper, and completes the gram weight detection of the trademark paper.

[0063] In other embodiments, a cover plate assembly is further provided in the detection space, and the cover plate assembly includes a cover plate 15 and at least two lifting devices 16. The cover plate 15 is arranged between the weighing module 3 and the CCD camera 5, and the cover plate 15 is made of transparent material. The fixed ends of at least two of the lifting devices 16 are diagonally arranged at the top of the base 1, and the lifting ends of at least two of the lifting devices 16 are connected to the cover plate 15. The lifting devices 16 are electrically connected to the power supply and the processing control unit.

[0064] Specifically, in order to prevent the cover plate 15 from contacting and squeezing the weighing module 3 when the cover plate 15 drops to the lowest point, it is defined that when the lifting stroke of the lifting device 16 is the smallest, the vertical distance between the end of the cover plate 15 close to the base 1 and the top end face of the base 1 is H, and the vertical distance between the top end of the weighing module 3 and the top end face of the base 1 is h, then H>h is satisfied.

[0065] Among them, in this embodiment, by setting the cover plate assembly, the trademark paper can be flattened to avoid inaccurate area information of the trademark paper collected due to warping or wrinkles on the trademark paper. However, since the cover plate assembly will affect the accuracy of the weight information collected on the trademark paper, it is necessary to first use the intelligent interactive display screen 4 to control the cover plate 15 to press down to flatten the trademark paper, then collect the area information of the trademark paper, and then raise the cover plate 15. When the cover plate 15 leaves the trademark paper, the weight information of the trademark paper is collected. The processing control unit calculates the gram weight information of the trademark paper based on the collected area information and weight information of the trademark paper, and the lifting device 16 can be an electric push rod.

[0066] In other embodiments, a horizontal detection component is provided at the top of the cover body 2, and the horizontal detection component includes a transverse horizontal detection device 17 and a longitudinal horizontal detection device 18. The transverse horizontal detection device 17 is arranged along the direction from the left side panel to the sliding door 10, and the longitudinal horizontal detection device 18 is arranged along the direction from the front side panel 7 to the back panel 8.

[0067] Among them, the staff can judge the parallelism of the device by observing the transverse horizontal detection device 17 and the longitudinal horizontal detection device 18 to prevent the accuracy of the weight information of the trademark paper from being affected by the tilt of the device. The transverse detection device 17 and the longitudinal horizontal detection device 18 can be level rulers sold on the market.

[0068] In summary, the embodiment of the present application arranges a plurality of light sources on the inner wall of the top end of the cover body, and arranges a CCD camera to shoot the trademark paper, and transmits the shot image to an image acquisition card electrically connected to the CCD camera for processing, and then outputs the processed image information to a processing control unit electrically connected to the image acquisition card to calculate the area of ​​the trademark paper and obtain the area information of the trademark paper, and arranges a weighing module on the base to obtain the weight information of the trademark paper, and outputs the weight information to a processing control unit electrically connected to the weighing module, and the processing control unit calculates the gram weight information based on the obtained weight information and area information of the trademark paper, and outputs the gram weight information of the trademark paper. The weight information is output to the intelligent interactive display screen for the staff to know, which solves the technical problems in the prior art that the production efficiency of cigarettes is low due to the low efficiency of the trademark paper weight detection, and the area verification of the trademark paper is inaccurate due to the errors in cutting, which leads to inaccurate data of the trademark paper weight detection and affects the quality of cigarette boxes and strip boxes. At the same time, the trademark paper is flattened by setting a cover plate assembly to further improve the accuracy of the trademark paper area information collection, thereby improving the accuracy of the trademark paper weight detection. By setting a horizontal detection assembly to judge the parallelism of the device, the accuracy of the trademark paper weight information collection is improved, thereby improving the accuracy of the trademark paper weight detection.
