[0023] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0024] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment one:

[0026] Reference Figure 1-6 A composite filter rod online microwave detection and rejection device comprises a support platform 1 and a filter rod body 3. Three groups of guide motors 10 are arranged on the top surface of the support platform 1. The output shafts of the three groups of guide motors 10 are respectively connected with a turning drum wheel 6, a detection drum wheel 8 and a rejection drum wheel 9. The surfaces of the turning drum wheel 6, the detection drum wheel 8 and the rejection drum wheel 9 are all circumferentially provided with a filter rod mounting groove 11. The filter rod mounting groove 11 is engaged with the surface of the filter rod body 3. A microwave detection component 5 is arranged on one side of the turning drum wheel 6, and a detection and rejection component 7 is arranged on one side of the rejection drum wheel 9. An electric control box 4 is arranged on the surface of the support platform 1. When the whole device is actually used, the filter rod body 3 is clamped mainly by the filter rod mounting groove 11 on the surfaces of the turning drum wheel 6, the detection drum wheel 8 and the rejection drum wheel 9 to form a transmission The conveying mechanism is convenient for transmitting and detecting mechanical energy of multiple groups of filter rod bodies 3. When the filter rod body 3 is detected and rejected on the surface, the filter rod body 3 is first engaged through the filter rod mounting groove 11 on the surface of the turning drum 6. After engagement, the guide motor 10 rotates to drive the turning drum 6 to rotate, so that the filter rod bodies 3 on the surface pass through the surface of the microwave detection component 5 one by one for microwave detection. Then, the detected filter rod bodies 3 are engaged and transmitted with the surface of the detection drum 8 through rotation until they are transmitted to the surface of the rejection drum 9. The rejection component 7 uses the detection result of the microwave detection component 5 to blow and reject unqualified filter rod bodies 3. The rejected filter rod bodies 3 fall along the filter rod rejection groove 12 on the surface of the support platform 1, completing the entire processing and rejection process.

[0027] When performing microwave detection on the surface of the filter rod body 3, since the microwave detection component 5 includes a microwave detection head 501 and a guide rail 502, the bottom surface of the guide rail 502 is bolted to the surface of the support platform 1, and an adjusting cylinder 503 is bolted to the top surface of the guide rail 502, and the movable end of the adjusting cylinder 503 is connected to the end of the microwave detection head 501, the microwave detection head 501 corresponds to the position of the filter rod mounting groove 11 on the surface of the turning drum 6, and the microwave detection head 501 can be driven by the adjusting cylinder 503 to move up and down to scan the surface of the filter rod body 3. The adjustable structure facilitates adaptive scanning of the microwave range of filter rod bodies 3 of different lengths. The scanning result is transmitted to the rejection component 7, and the rejection component 7 is controlled by the electric control box 4 to reject the filter rod body 3 at the specified position.

[0028] When the filter rod body 3 is being removed, since the removal assembly 7 includes a pressure-regulated air supply box 703 and an air blowing head 701, an air supply pipe 702 is connected between the air blowing head 701 and the pressure-regulated air supply box 703, an L-shaped support frame 2 is bolted to one side of the top surface of the support platform 1, and the end of the L-shaped support frame 2 is bolted to the top of the air blowing head 701, the air is supplied to the air blowing head 701 through the pressure-regulated air supply box 703, connected through the air supply pipe 702, and the air blowing pressure is controlled by the pressure-regulated air supply box 703, which is convenient for filtering filters of different weights. The filter rod body 3 is provided with corresponding air blowing force, which is convenient for the rapid removal of the filter rod body 3. The air blowing head 701 removes the filter rod body 3 in the vertical direction along the top of the removal drum 9. Since a filter rod removal groove 12 is provided on the top surface of the support platform 1 near the removal roller position, and the filter rod removal groove 12 penetrates the top surface of the support platform 1, and the filter rod removal groove 12 corresponds to the vertical position of the filter rod mounting groove 11 on the surface of the removal drum 9, the removed filter rod body 3 falls into the filter rod removal groove 12 for transportation, thereby completing the removal of the filter rod.

[0029] Other limiting structures of the entire device are as follows: the friction force between the filter rod mounting groove 11 and the filter rod body 3 is 1.5-2 times the weight of the filter rod body 3 itself, which prevents the filter rod body 3 and the filter rod mounting groove 11 from falling off after being engaged, and maintains the stability of the connection engagement; the turning drum 6, the detection drum 8 and the rejection drum 9 have the same thickness, and the adjacent guide motors 10 are independently controlled, which is convenient for controlling the filter rod body 3 for transmission. Specific embodiment 2:

[0031] Reference Figure 1-6The turning drum 6, the detection drum 8 and the rejection drum 9 are staggered in the vertical direction, and the bottom surface of the detection drum 8 is coplanar with the top surface of the rejection drum 9, and the top surface of the rejection drum 9 is coplanar with the top surface of the turning drum 6. When the filter rod body 3 between adjacent drum wheels is exchanged, taking the turning drum 6 and the detection drum 8 as an example, when the turning drum 6 clamps the filter rod body 3, it clamps the lower half of the filter rod body 3, and the turning drum 6 rotates to a position close to the detection drum 8, and the filter rod mounting groove 11 on the surface of the detection drum 8 contacts and engages with the upper part of the filter rod body 3. As the turning drum 6 and the detection drum 8 rotate in opposite directions, the filter rod body 3 gradually detaches from the inside of the turning body, thereby realizing the conversion of the filter rod body 3 between adjacent drum wheels. Specific embodiment three:

[0033] Reference Figure 1-6 In actual use, in order to reduce processing costs, for a small number of filter rod bodies 3, only one set of drum wheels can be set on the surface of the support platform 1, such as only one set of turning drum wheels 6 to engage the filter rod body 3, and the position of the rejection component 7 is adjusted to be located directly above the microwave detection component 5, so that the filter rod installation groove 11 vertically corresponding to the bottom end of the air blowing head 701 and the filter rod installation groove 11 opposite to the side of the microwave detection head 501 are the same group, so that when the microwave detection component 5 detects an unqualified filter rod body 3, the air blowing head 701 directly runs to perform vertical rejection. In this way, compared with the above-mentioned way, the filter rod body 3 is quickly positioned without the need for calculation. After the microwave detection component 5 transmits the unqualified signal to the electric control box 4, the electric control box 4 transmits the opening signal to the rejection component 7, and the rejection component 7 directly runs to perform vertical rejection without the need for positioning. Specific embodiment four:

[0035] Reference Figure 1-6 When multiple drum wheels are used for transmission, since the rotation rate of the drum wheel can be calculated according to the time and the operating rate of the guide motor 10, and according to the filter rod mounting groove 11 set on the surface of the drum wheel, the time t required for passing through a filter rod mounting groove 11 can be obtained, thereby combining the operating speeds of the three drum wheels to obtain the time for the unqualified filter rod body 3 to reach the rejection position from the detection position of the microwave detection component 5, thereby driving the air blowing head 701 to open for rejection, and the specific calculation formula is set in combination with the existing technology and the actual usage scenario parameters. Specific embodiment five:

[0037] Reference Figure 1-6 ,When the whole device is actually used, the filter rod body 3 with the following parameters is mainly eliminated:

[0038] This microwave probe is integrated with a photoelectric measuring tube for gap detection. Due to the high frequency and fast change speed of microwave signals, it is extremely sensitive to changes in the inherent resonant frequency and amplitude of different materials, and it will not cause any damage to the material being detected, so it has the characteristics of online, real-time, rapid and non-destructive detection of material properties. The microwave power used in this product is extremely small, only about 10mW, so it will not cause any pollution or harm to the workplace and operators. Different substances will generate different microwave signals when passing through the microwave resonant cavity. The filter rods made of material A and B in the composite filter rod should generate different microwave signals when passing through the microwave resonant cavity. The signals of the composite filter rod in the microwave resonant cavity are analyzed and compared, and the filter rods made of material A and B can be clearly distinguished from the microwave signals.

[0039] The entire device of the present application, in addition to the electric control box 4, also includes a microwave electromagnetic field cavity assembly, a smoke guide tube assembly, an air path assembly, a temperature control assembly, a shell assembly, a dedicated microwave source and control circuit, a detection and amplification circuit, a photoelectric measuring tube component, a data signal processing system, a signal output drive, a rejection actuator, etc. The specific content and structure can be set according to the existing technology.

[0040] The filter rod body 3 is generally a spliced ​​structure, such as a structure in which segments A and B are spliced ​​together, or a structure in which multiple segments ABCDE are spliced ​​together.

[0041] When two adjacent sections, such as A+B, are not equal to the target total length, and when the error is greater than the set value, it is determined that there is a gap in the composite filter rod and a rejection signal is output;

[0042] Elimination conditions:

[0043] (A+B)-(a+b)≥︳0.3︳mm

[0044] Among them: A+B equals the theoretical length of segments A and B, and a+b equals the measured length of segments A and B.

[0045] The filter rod is misplaced; that is, the filter rod of section B is mistakenly placed where the filter rod of section A should be placed, or vice versa. The misplaced filter rod will be rejected;

[0046] Phase shift; that is, the length of the filter rods in section A and section B does not meet the process quality requirements;

[0047] When the length of section A is not equal to the length of section E, and when the error is greater than the set value, the composite filter rod is judged to be phase-deviation and a rejection signal is output;

[0048] Elimination conditions:

[0049] ae≥︳1.0︳mm

[0050] A is the theoretical length of section A, E is the theoretical length of section E, a is the measured length of section A, and e is the measured length of section E.

[0051] In summary:

[0052] The filter rod body 3 is clamped and converted by the turning drum 6, the detection drum 8 and the rejection drum 9 on the surface of the support platform 1, and the surface of the filter rod body 3 is scanned by the microwave detection head 501 of the microwave detection component 5 to locate the unqualified filter rod body 3, and the filter rod body 3 is rejected by the air blowing head 701 and the pressure-regulating air supply box 703 of the rejection component 7, thereby realizing the detection, screening and rejection processing of the surface of the filter rod body 3. The degree of automation is high, and the qualified rate of the filter rod body 3 can be improved by automatic monitoring and rejection, thereby improving the production quality. It has the characteristics of being able to detect material properties online, in real time, quickly and non-destructively.
