[0003] The existing thickness detection method of the wrapping paper used in tobacco section is generally to detect the thickness of the wrapping paper used in tobacco section with photoelectric detector, although this method can complete the process of detecting the thickness of the wrapping paper used in tobacco section, but there are still the following defects in actual use process:
[0004] (1) Since the manufacturers of the wrapping paper are different, the thickness of the wrapping paper produced by different manufacturers is also different, when detecting the wrapping paper with different thickness with photoelectric detector, since the thickness of the wrapping paper produced by different manufacturers is quite different, the error of photoelectric detector is also large, and the condition of misjudging the qualified thickness of the wrapping paper often occurs, which indirectly affects the production efficiency of cigarette;
[0005] (2) Since the equipment for producing cigarette needs to produce products of different brands, the thickness of tobacco section material needed for producing different brands is also different, when detecting the wrapping paper with different thickness with the same specification of photoelectric detector, since the thickness of the wrapping paper produced by different manufacturers is quite different, the photoelectric detector for detecting the wrapping paper with different thickness for producing different brands of cigarette at different time often misjudges the qualified thickness of the wrapping paper.

[0028] EMBODIMENT
[0029] The existing thickness detection method for the wrapping paper of the tobacco rod is generally to use a photoelectric detector to detect the thickness of the wrapping paper of the tobacco rod. Although this method can complete the process of detecting the thickness of the wrapping paper of the tobacco rod, in actual use, there still exist the following problems: when detecting the thickness of the wrapping paper of the tobacco rod of different brands or the wrapping paper of the tobacco rod produced by different manufacturers, due to the different thickness of the wrapping paper of the tobacco rod of different brands or the big difference in the thickness of the wrapping paper of the tobacco rod produced by different manufacturers, the photoelectric detector for detecting the thickness of the wrapping paper of the tobacco rod appears the condition of false detection due to big error.
[0030] Therefore, the present application provides a thickness detection teaching device to solve the problem that when detecting the thickness of the wrapping paper of the tobacco rod of different brands or the wrapping paper of the tobacco rod produced by different manufacturers, due to the different thickness of the wrapping paper of the tobacco rod of different brands or the big difference in the thickness of the wrapping paper of the tobacco rod produced by different manufacturers, the photoelectric detector for detecting the thickness of the wrapping paper of the tobacco rod appears the condition of false detection due to big error.
[0031] Specifically, please refer to Figure 1 , Figure 2 and Figure 3 , a thickness detection teaching device, comprising a microwave transmitting element 1, a microwave receiving element 2, a thickness detector 4 and an industrial computer 5; the microwave transmitting element 1 and the microwave receiving element 2 are connected with the thickness detector 4; the thickness detector 4 is provided with a teaching button 8 and a digital display screen 9 on the outer wall; and the thickness detector 4 is in communication connection with the industrial computer 5.
[0032] In actual use, when teaching the thickness detector 4, according to the different thickness of the material to be detected (the material to be detected: the wrapping paper of the tobacco rod) by the thickness detector 4, first, a teaching sample corresponding to the thickness of the wrapping paper of the tobacco rod is placed in the detection area between the microwave transmitting element 1 and the microwave receiving element 2, then the teaching button 8 on the side wall of the thickness detector 4 is turned on, the microwave transmitted by the microwave transmitting element 1 passes through the teaching sample to the microwave receiving element 2, then the microwave receiving element 3 transmits the feedback information to the thickness detector 4, and the digital display screen 9 on the thickness detector 4 displays the detection value at this time, which is used as the detection threshold value of the thickness detector 4 to complete the teaching process of the thickness detector 4.
[0033] When the cigarette wrapper of the corresponding thickness of the teaching sample is detected by the thickness detector 4 with the detection threshold set above, the cigarette wrapper is placed in the detection area between the microwave emitting element 1 and the microwave receiving element 2, and the microwave emitted by the microwave emitting element 1 passes through the cigarette wrapper to the microwave receiving element 2, and the microwave receiving element 2 receiving the feedback information transmits the information back to the thickness detector, if the detected value under this condition is higher than the detection threshold, the cigarette wrapper is a qualified product; if the detected value under this condition is lower than the detection threshold, the cigarette wrapper is an unqualified product, and the detection accuracy of the cigarette wrapper is further improved.
[0034] It should be noted that the teaching sample can be made according to the different thicknesses of the cigarette wrapper, and the teaching sample is generally 1.2 times the thickness of the material to be detected; or when the thickness of the material to be detected is very thin (the thickness is less than 50μ), the thickness of the teaching sample is selected as the thickness of the raw material plus 20μ.

The rejection mechanism can be arranged on the downstream conveying line of the conveying wrapper, and the microwave emitting element 1 and the microwave receiving element 2 are arranged on the upstream conveying line of the conveying wrapper. The rejection mechanism is generally a gas nozzle connected with a gas source and provided with a solenoid valve, and the industrial computer 5 is in communication connection with the solenoid valve on the gas nozzle, that is, when the feedback information (feedback signal) received by the microwave receiving element 2 is higher than the detection threshold set by the thickness detector 4, the thickness detector 4 sends a low-level signal information to the industrial computer 5, and the industrial computer 5 does not control the rejection mechanism in communication connection with the industrial computer 5 to act.
[0037] When the feedback information (feedback signal) received by the microwave receiving element 2 is lower than the detection threshold set by the thickness detector 4, the thickness detector 4 sends a high-level signal information to the industrial computer 5, and the industrial computer 5 controls the rejection mechanism in communication connection with the industrial computer 5 to act, so as to reject the unqualified materials.

[0040] In actual application, when the thickness detector is taught with the assistance of the microwave emitting probe and the microwave receiving probe, the microwave emitted by the microwave emitting probe passes through the sample to the microwave receiving probe, then the microwave receiving probe transmits the feedback information to the thickness detector 4, and the detection value at this time is displayed on the digital display screen 9 of the thickness detector 4, which is used as the detection threshold of the thickness detector 4 to complete the teaching process of the thickness detector 4.
[0041] It should be noted that the microwave probe is a prior art and is not improved or designed, so its structure is not described in detail.
