DETAILED DESCRIPTION

[0019] In order to more clearly illustrate the embodiments of the present invention and the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work. In addition, the design orientation only represents the relative position relationship between the components, not the absolute position relationship.

[0020] In a first aspect, an embodiment of the present invention provides a tobacco filling value detection device, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , mainly includes a frame 2, a tobacco filling measuring instrument 3, a moving component 4, a measuring cup 5 and a cleaning component 6.

[0021] In the embodiment of the present application, the entire tobacco filling value detection device is arranged around the tobacco conveying line, and the tobacco filling value detection device includes a frame 2, a detection space 1 is arranged on the frame 2, and a tobacco filling measuring instrument 3 is arranged in the detection space 1. A moving component 4 and a cleaning component 6 are arranged on the frame 2, and a measuring cup 5 is arranged on the moving component 4. The moving component 4 can drive the measuring cup 5 to move. When it is necessary to detect the tobacco filling value, the moving component 4 first drives the measuring cup 5 to move to the tobacco conveying line, and the moving component 4 moves the measuring cup 5 to guide the tobacco on the tobacco conveying line into the measuring cup 5, and then the moving component 4 drives the measuring cup 5 containing the tobacco to move to the tobacco filling measuring instrument 3 to detect the tobacco filling value, and finally the moving component 4 moves the measuring cup 5 to the arrangement position of the cleaning component 6, and the cleaning component 6 clears the tobacco in the measuring cup 5, so that the next tobacco filling value detection can be performed. Compared with the prior art, the operator takes samples on site, transfers the samples to the laboratory, takes quantitative samples into the measuring cup 5 (weighing about 10g), and then puts them into the filling value detector. After the data is obtained, the operator manually records the measurement results. In this application, the entire process of tobacco filling value detection is realized by moving the measuring cup 5 by the moving component 4, avoiding the differences caused by different operating techniques of the operators and the changes in the state of tobacco in the process of transferring the samples to the laboratory, improving the accuracy of the detection, and reducing the labor intensity.

[0022] In one embodiment, a weighing piece 7 is provided on the mobile component 4, and the weighing piece 7 is rotatably connected to the mobile component 4. When the mobile component 4 obtains the measuring cup 5 containing tobacco from the tobacco conveying line, the weighing piece 7 abuts against the measuring cup 5 to weigh the weight of the tobacco. When the weight of the tobacco does not meet the detection standard, the current tobacco filling value is not recorded to improve the accuracy of subsequent tobacco filling value detection.

[0023] In one embodiment, the moving assembly 4 includes a rotating seat 41, a receiving seat 42, and a plurality of mechanical arms 43 arranged between the rotating seat 41 and the receiving seat 42. The rotating seat 41 is rotatably connected to the frame 2, and the plurality of mechanical arms 43 are rotatably connected to each other. The rotating seat 41 is rotatably connected to the frame 2, the rotating seat 41 is rotatably connected to the mechanical arm 43, the receiving seat 42 is rotatably connected to the mechanical arm 43, the weighing piece 7 and the gripper 44 are both arranged on the receiving seat 42, and the gripper 44 is used to grab the measuring cup 5.

[0024] Furthermore, the weighing seat includes a weighing sensor 71, a transition block 72 and a turntable 73. One end of the transition block 72 is connected to the weighing sensor 71, and the other end is connected to the turntable 73. The turntable 73 is rotatably connected to the receiving seat 42. When the mechanical arm 43 drives the measuring cup 5 to grab the tobacco, the turntable 73 rotates, thereby driving the weighing sensor 71 to rotate with the turntable 73 as the center of the circle, so that the detection surface of the weighing sensor 71 faces downward, thereby preventing the tobacco from adhering to the weighing sensor 71. When the weight of the tobacco in the measuring cup 5 needs to be weighed, the turntable 73 rotates and drives the weighing sensor 71 to move to the bottom of the measuring cup 5 to measure the weight of the tobacco in the measuring cup 5.

[0025] Preferably, the moving component 4 also includes an abutment screw 45, which is threadedly connected to the transition block 72. When the turntable 73 rotates to drive the weighing sensor 71 to abut against the measuring cup 5, the abutment screw 45 will also abut against the receiving seat 42 driven by the turntable 73. The abutment screw 45 can be used to prevent the weighing sensor 71 from moving due to inertia during rotation and colliding with the measuring cup 5, thereby ensuring the accuracy of the weighing sensor 71 in detecting weight.

[0026] Specifically, the gripper 44 includes a slide rail 441 arranged on the receiving seat 42, two sliders 442 arranged on the slide rail 441, and both sliders 442 are provided with gripping plates 443. The two sliders 442 move towards each other, thereby driving the two gripping plates 443 to abut against the measuring cup 5, and then the gripping plates 443 grip the measuring cup 5.

[0027] Furthermore, a plurality of limit blocks 444 are provided on the gripping plate 443, and a plurality of limit holes 445 are provided on the measuring cup 5. When the gripping handle 44 abuts against the measuring cup 5, the limit blocks 444 are embedded in the limit holes 445 to ensure that the measuring cup 5 does not shake during the gripping process, thereby improving the stability of the measuring cup 5 during the movement.

[0028] In one embodiment, the cleaning component 6 includes a cleaning rod 61, one end of which is connected to the frame 2, and the other end is used to remove the tobacco in the measuring cup 5. When the moving component 4 moves the measuring cup 5 to the arrangement position of the cleaning rod 61, the cleaning rod 61 will abut against the inner wall of the measuring cup 5, and then the moving component 4 drives the measuring cup 5 to move, so that the cleaning rod 61 and the inner wall of the measuring cup 5 produce relative movement, and then the tobacco on the inner wall of the measuring cup 5 is removed, so as to detect the tobacco filling value next time. The tobacco on the measuring cup 5 is removed by the cleaning rod 61, so as to improve the accuracy of the next tobacco filling value detection.

[0029] Furthermore, the cleaning component 6 also includes a plurality of blowing units 62 arranged around the cleaning rod 61, and the blowing units 62 blow air toward the measuring cup 5 to further remove the tobacco on the inner wall of the measuring cup 5, so as to improve the accuracy of the next tobacco filling value detection. At the same time, when the moving component 4 moves the measuring cup 5 containing tobacco to the moving path of the tobacco filling measuring instrument 3, a plurality of blowing units 62 are added to remove the tobacco attached to the measuring cup 5 and the moving component 4, so as to improve the accuracy of the subsequent tobacco filling value detection.

[0030] Specifically, the blowing unit 62 may be an air valve, an air duct or other air-blowing equipment.

[0031] In one embodiment, a plurality of universal wheels 21 and a plurality of support plates are further provided at the bottom of the frame 2. The support plates are used to increase the contact area between the entire device and the ground when the universal wheels 21 are not rotating, thereby preventing the entire detection device from moving during the detection process and improving the stability of the entire detection process.

[0032] In a second aspect, an embodiment of the present invention provides a method for detecting a tobacco filling value, using the above-mentioned tobacco filling value detection device, comprising the following steps: S1: The control unit of the tobacco filling value detection device controls the weighing sensor 71 to rotate so that the detection surface of the weighing sensor 71 faces downward. The control unit of the tobacco filling value detection device controls the gripper 44 of the moving component 4 to grab the measuring cup 5 and drive the measuring cup 5 to move, and then immerse the measuring cup 5 in the tobacco transported by the tobacco transport line, thereby obtaining the measuring cup 5 filled with the tobacco to be measured, and then remove the tobacco outside the measuring cup 5 through multiple blowing units 62. The control unit of the tobacco filling value detection device controls the weighing sensor 71 to rotate so that the weighing sensor 71 and the measuring cup 5 are offset, and the weight of the tobacco in the measuring cup 5 is measured, and the tobacco weight data obtained by weighing is transmitted to the data platform through the communication system. The data platform obtains the net weight of the tobacco by calculation, and screens the net weight data according to the setting, and eliminates the net weight data of the tobacco that does not meet the filling value detection standard, thereby improving the accuracy and efficiency of subsequent data processing. After measuring the weight of the tobacco in the measuring cup 5, the weighing sensor 71 is rotated so that the detection surface of the weighing sensor 71 faces downward.

[0033] S2: The control unit of the tobacco filling value detection device controls the moving component 4 to drive the measuring cup 5 to move to the tobacco filling measuring instrument 3, and then detects the tobacco filling value through the tobacco filling measuring instrument 3. When the detection work is completed, the detector will transmit the detected data back to the data platform. The data platform receives the detection data and calculates the average filling value data within each batch time based on data records such as detection time, sampling weight, and filling value detection results.

[0034] S3: The control unit of the tobacco filling value detection device controls the moving component 4 to drive the measuring cup 5 to move to the arrangement position of the cleaning component 6, and the cleaning component 6 removes the tobacco in the measuring cup, specifically, the cleaning rod 61 contacts the inner wall of the measuring cup 5, and then the moving component 4 drives the measuring cup 5 to make a circular motion with the cleaning rod 61 as the center, thereby removing the tobacco on the inner wall of the measuring cup 5. Repeat the above steps to perform the next tobacco filling value detection.
