[0022] In order to make the technical means, creative features, objectives and effects of the utility model easier to understand, the utility model is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the utility model, 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 utility model.
[0023] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment one:
[0025] Reference Figure 1-6, an online filter rod capsule detection device based on microwave method, comprising a support bracket 4 and a main material conveyor belt 1, an auxiliary material conveyor belt 2 is arranged on the top of the main material conveyor belt 1, support brackets 4 are symmetrically distributed on both sides of the main material conveyor belt 1, a microwave detection probe 9 is connected to the top of the support bracket 4, two groups of servo motors 5 are vertically arranged on the side of the support bracket 4, and the ends of the servo motors 5 are respectively connected with a detection drum wheel 6 and a transmission drum wheel 7, and the detection drum wheel 6 is located on the top of the transmission drum wheel 7, and an air blowing component 10 is arranged between adjacent servo motors 5, and the surfaces of the detection drum wheel 6 and the transmission drum wheel 7 are circumferentially distributed with limit arc grooves 11, and the limit arc grooves 11 are arranged inside the limit arc grooves A filter body 8 is provided in the part. When the whole device is actually used, an external connection controller is used to control and connect the microwave detection probe 9 and the air blowing assembly 10. The microwave detection probe 9 is mainly used to scan the filter body 8 engaged with the limit arc groove 11 on the surface of the detection drum 6 to detect the existence of the beads inside. When the detection is used, the filter body 8 to be detected is inserted into the surface of the detection drum 6 along one end of the limit arc groove 11, and each limit arc groove 11 on the surface of the detection drum 6 is distributed inside. The detection drum 6 is driven to rotate by the servo motor 5, so that the filter body 8 engaged with the surface of the detection drum 6 and the microwave detection probe 9 are aligned. Corresponding to the position, the microwave detection probe 9 operates to perform scanning detection. After the detection, the servo motor 5 rotates a fixed angle, and the angle value keeps the limit arc groove 11 at the next position just overlapping with the limit arc groove 11 at the previous position, thereby driving the detection drum 6 to rotate one circle to realize the detection of all filter bodies 8 on the surface of one side. During the detection process, for the filter body 8 without beads inside, the microwave detection probe 9 sends a signal to the external controller for marking and recording. Since the rotation angle of the servo motor 5 is fixed, according to the structure shown in the figure, the microwave detection probe 9 and the air blowing assembly 10 are distributed symmetrically on the upper and lower sides of the detection drum 6. 180 degree position, after marking the problematic filter body 8, a signal is transmitted to the air blowing assembly 10 through the controller. After the servo motor 5 rotates 180 degrees, the problematic filter body 8 just rotates to the corresponding position of the end of the air blowing assembly 10. At this time, the air blowing assembly 10 is running, and the filter body 8 is removed from the surface of the detection drum 6, and the removal of the quality filter assembly is completed, so that the whole device can quickly detect, remove and transfer the filter body 8, with a high degree of integration and simple operation, without manual operation, thereby improving the accuracy and efficiency of the detection of the filter body 8, improving the quality of the filter body 8, and facilitating rapid transportation and use.
[0026] To facilitate the auxiliary installation of the filter body 8, a limit assembly 12 is provided on the surface of the detection drum 6 and the conveying roller. A limit controller 1201 is provided on the side of the detection drum 6 surface away from the servo motor 5. A limit suction hole 1202 is provided on the surface of the detection drum 6 at a position corresponding to the limit arc groove 11. An electric-controlled sealing valve 1203 is provided inside the limit suction hole 1202. The electric-controlled sealing valve 1203 is electrically connected to the limit controller 1201. The limit assembly 12 limits and clamps the filter body 8 through the limit arc groove 11. After the filter body 8 is inserted into the limit arc groove 11, the limit controller 1201 drives the electric-controlled sealing valve 1203 at this position to close, and extracts air while closing to form a negative pressure environment, thereby sucking the filter body 8 through the limit suction hole 1202. , to limit the filter body 8, since the limiting arc groove 11 corresponds to the limiting suction hole 1202 one by one, the limiting suction hole 1202 corresponds to the electrically controlled sealing valve 1203 one by one, and the adjacent electrically controlled sealing valves 1203 are independently controlled by the limiting controller 1201. Therefore, when the filter body 8 is released, the limiting controller 1201 drives the electrically controlled sealing valve 1203 at the corresponding position to open. At the same time, the air is no longer squeezed, and the suction force is removed. The filter body 8 falls from the inside of the limiting arc groove 11 to the surface of the main material conveyor belt 1 for transportation. When the filter is removed, the electrically controlled sealing valve 1203 remains closed, and the blowing force of the air blowing component 10 is set to be greater than the suction force, so that the filter body 8 can be removed and separated along the side end when the electrically controlled sealing valve 1203 of the limiting component 12 is not closed.
[0027] When the filter body 8 is transferred between the detection drum 6 and the conveying drum 7 for use, the qualified filter bodies 8 are transferred to the conveying drum 7, and the unqualified ones are directly removed from the surface of the detection drum 6. When the qualified filter bodies 8 are transferred, the detection drum 6 rotates the filter body 8 to the position closest to the top of the conveying drum 7, and the limiting arc groove 11 on the surface of the conveying drum 7 engages with the end of the filter body 8. At this time, the electrically-controlled sealing valve 1203 opens to release the filter body 8 at the position clamped by the conveying drum 7 on the surface of the detection drum 6, and the electrically-controlled sealing valve 1203 at the clamping position of the conveying drum 7 opens to realize the handover and transfer of the filter body 8.
[0028] In order to facilitate the sorting and discharging of the filter body 8, power brackets 3 are symmetrically arranged on both sides of the main material conveyor belt 1. The top of the side of the power bracket 3 is connected to the two ends of the auxiliary material conveyor belt 2. The main material conveyor belt 1 and the auxiliary material conveyor belt 2 are independently controlled. Unqualified filter bodies 8 can be removed by the air blowing component 10 and enter the surface of the auxiliary material conveyor belt 2. Qualified filter bodies 8 are transported by the conveying drum wheel 7 to enter the main material conveyor belt 1 for sorting and transportation / removal of defective products. The surface of the power bracket 3 is provided with two groups of gear shafts with motors. The surface of the gear shaft is meshed with the inner wall of the main material conveyor belt 1. The gear shaft is driven to rotate by the motor to drive the main material conveyor belt 1. The auxiliary material conveyor belt 2 has the same operating principle as the main material conveyor belt 1.
[0029] Other limiting structures of the entire device are as follows: the microwave detection probe 9 and the servo motor 5 are both connected to the surface bolts between the supports to maintain the stability of the connection and prevent them from falling off; the detection drum 6 and the conveying drum 7 have the same surface connection structure, and the detection drum 6 and the conveying drum 7 are independently controlled by each other; the side vertical center line of the air blowing assembly 10 coincides with the side vertical center line of the detection drum 6; the horizontal center line of the air blowing assembly 10 is tangent to the arc surface at the top of the conveying roller; the positions of the microwave detection probe 9 and the air blowing assembly 10 are kept corresponding, so as to facilitate the positioning of the unqualified filter body 8. Specific embodiment 2:
[0031] Reference Figure 1-6 Different substances in the microwave detection probe 9 will generate different microwave signals when passing through the microwave resonance cavity. The filter rod made of segment A and the filter rod made of segment B in the composite filter rod should generate different microwave signals when passing through the microwave resonance cavity. The microwave detection probe 9 analyzes and compares the signals of the composite filter rod in the microwave resonance cavity. The filter rod made of segment A and the filter rod made of segment B can be clearly distinguished from the microwave signals, thereby realizing the detection of beads in the mouthpiece, detecting the change in phase and amplitude of the microwave signal after reflection from the substance being tested, and comparing it with the microwave signal from a cigarette without beads. Specific embodiment three:
[0033] Reference Figure 1-6 In the present application, the microwave detection probe 9, when in use, has at least the following structural contents: including the microwave detection probe 9, a control system, a microwave signal transceiver antenna, a phase and amplitude detection circuit, a signal comparison and processing circuit, a signal output drive, a rejection actuator, etc.
[0034] The microwave signal emitted by the microwave detection probe 9 passes through the detection drum 6 and is irradiated to the filter body 8 of the cigarette by the microwave transceiver antenna. The microwave signal passes through the filter body 8 and the bead particles therein, reaches the metal surface of the rotating drum, and is reflected by it. The reflected microwave signal again passes through the filter rod and the bead particles therein, reaches the microwave transceiver antenna, and then the detection drum 6 separates the reflected signal and enters the phase and amplitude detection amplifier. The reflection method actually just allows the microwave signal to pass through the substance to be detected twice, so that the difference between the incident signal and the reflected signal is more obvious.
[0035] The microwave detection and control system can be powered off or on at will according to the needs of the operator, and can work normally without preheating or zeroing. The detection and control accuracy and reliability are not affected. The transmission power of the microwave detection probe 9 is very small, hundreds of times smaller than the microwave power of an ordinary mobile phone, and has no harm or impact on the surrounding personnel and the environment. The entire detection system has undergone various strict inspections and tests such as high and low temperature tests, vibration tests and continuous power-on tests. The software and hardware are safe, stable and reliable, and it is relatively easy to use and maintain. Specific embodiment four:
[0037] Reference Figure 1-6 A channel formed by circumferentially distributed limit suction holes 1202 is provided inside the detection drum 6, and an electrically controlled sealing valve 1203 is provided inside each channel. The positioning is controlled one by one through a limit controller 1201. The limit controller 1201 is electrically connected to a controller connected to the outside of the microwave detection probe 9 of the entire device, so as to facilitate the unloading of the filter body 8.
[0038] In summary:
[0039] The filter body 8 is clamped by setting limiting arc grooves 11 on the surfaces of the vertically distributed detection drum 6 and the conveying drum 7, and the microwave detection probe 9 on the top is used for scanning and detection, so that unqualified filter bodies 8 can be rejected by the air blowing component 10 and enter the surface of the auxiliary material conveyor belt 2, and qualified filter bodies 8 are conveyed by the conveying drum 7 to the main material conveyor belt 1 for material separation and transportation / removal of defective products, so that the whole device can quickly detect, reject and separate the filter bodies 8, with a high degree of integration and simple operation, without manual operation, thereby improving the accuracy and efficiency of the detection of the filter body 8, improving the quality of the filter body 8, and facilitating rapid transportation and use.
