[0027] like Figure 1 As shown, the device for automatically adjusting the cigarette hardness test position provided in this embodiment includes: columns 5 set on both sides of the hardness unit of the comprehensive test platform, a clamping base 7 set at the lower end of each column 5, a clamping piece 6 movably set above each clamping base 7, a belt 1 set above the column 5, a camera 9 set below the belt 1, a guide rail 3 set on the front side of the belt 1, a cigarette push rod 4 set on the guide rail 3, a push piece 8 set at the end of the cigarette push rod 4, and a processor connected to the camera 9 and the cigarette push rod 4.

[0028] The pusher 8 is made of silicone to avoid damaging the cigarette. In other embodiments of this invention, the pusher 8 may also be made of soft materials such as rubber to avoid damaging the cigarette. It should be noted that this invention does not specifically limit the material of the pusher 8.

[0029] Furthermore, the camera 9 is fixed below the belt 1 by screws, and the camera 9 is specifically used to acquire images of the cigarette to be tested. In some embodiments of this utility model, the camera 9 is a CCD camera. It should be noted that this utility model does not specifically limit the type and model of the camera 9.

[0030] Furthermore, the belt 1 is connected to a motor 2, which drives the belt 1 to rotate clockwise or counterclockwise.

[0031] Furthermore, the processor is specifically used to determine the specifications of the cigarette to be tested based on the image captured by the camera 9, and then determine the cigarette hardness test position based on the specifications of the cigarette to be tested; the cigarette pusher 4 is specifically used to push the cigarette to be tested to the test position based on the cigarette hardness test position determined by the processor.

[0032] Furthermore, each of the clamping plates 6 is clamped on both sides of the hardness unit of the integrated testing platform, serving as a fixing device, and the height of each clamping plate 6 is adjusted by a nut. The clamping base 7 below the clamping plate 6 is fixed to the corresponding column 5.

[0033] Furthermore, the upper end of the cigarette pusher 4 is connected to the belt 1 via a clamp. The cigarette pusher 4 can rotate with the belt 1 and reciprocate within the guide rail 3, thereby pushing the cigarette to the corresponding test position on the test platform and then resetting.

[0034] During operation, the camera 9 takes pictures of the cigarette sample to collect the original image and transmits it to the processor. The processor then calculates the sample length to obtain the measured cigarette specifications. Based on the cigarette specifications, the processor calculates and sets the pushing distance of the push rod 4 to l=Dd, where D is the distance from the center of the pressing test head to the initial position of the push rod, and d is the distance from the middle of the cigarette to the end face of the filter.

[0035] Furthermore, such as Figure 2 As shown, the specific testing process is as follows:

[0036] 1. Start the integrated testing platform and hardness testing position adjustment device;

[0037] 2. When the first test sample enters the hardness unit test stand, the camera 9 takes pictures of the cigarette sample to collect the original image, and then transmits it to the processor of the test system.

[0038] 3. The processor analyzes and processes the acquired raw images to measure the length of the cigarette sample. If the measured length does not meet the cigarette design requirements, the image is retaken and measured. If the measured length meets the cigarette design requirements, the system identifies the corresponding cigarette specifications.

[0039] 4. When the sample to be tested is a regular cigarette, based on the distance D from the center of the pressure test head to the initial position of the push rod, and the distance d from the middle of the sample cigarette to the end face of the filter tip d=55mm, the system calculates and sets the pushing distance of the push rod 4 to l=D-55; when the sample to be tested is a short cigarette, based on d=50, the system calculates and sets the pushing distance of the push rod 4 to l=D-50; when the sample to be tested is a medium cigarette, based on d=60, the system calculates and sets the pushing distance of the push rod 4 to l=D-60; when the sample to be tested is a short cigarette, based on d=64, the system calculates and sets the pushing distance of the push rod 4 to l=D-64.

[0040] 5. Based on the pushing distance set by the system, the cigarette pusher 4 pushes the cigarette sample to the test position for hardness measurement. At this point, the hardness test position adjustment of the sample is complete.

[0041] The device for automatically adjusting the cigarette hardness test position provided in this embodiment of the utility model is based on image processing technology. It directly adjusts the hardness test position during the test according to the length of the cigarette, eliminating the need to manually mark the sample and adjust the test position before the test, thus simplifying the operation steps. Moreover, it can avoid deviations in the test results caused by human error, further ensuring the consistency and accuracy of the test results.
