Abstract
Description
Technical Field
[0001] The utility model relates to a cigarette wire feeding pipeline air leakage detection device, belonging to the technical field of pipeline air leakage detection. Background Art
[0002] Studies have shown that the wind speed of the wind-forced wire feeding of cigarette making machines affects the physical quality of cigarettes, and different wind speeds of wind-forced wire feeding have a significant impact on the standard deviation of cigarette quality. At present, the wind speed of the wind-forced wire feeding pipeline is generally controlled at 17-20m / s. Since the wire feeding pipeline has many corners and is not a straight pipeline, there are many pipeline interfaces. In addition, the pipeline vibrates greatly. During long-term use, air leakage is prone to occur at the interface, which makes the pipeline wind speed lose consistency. The wind speed in the front section of the leak is high, and the wind speed in the back section is low, which affects the production quality of cigarettes. Utility Model Content
[0003] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a cigarette wire feeding pipeline leakage detection device, which can quickly detect the pipeline leakage position to prevent the pipeline leakage from affecting the production quality of cigarettes.
[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A pipeline connecting ring is connected between two adjacent wire feeding connecting pipelines, a fixing plate is installed on the surface of the pipeline connecting ring, a motor is fixedly installed on the surface of the fixing plate, a power switch of the motor is electrically connected to the output end of the signal acquisition controller, and a cam is installed on the output shaft of the motor.
[0007] A protective frame is installed on the surface of the fixed plate, and a movable plate is slidably connected inside the protective frame. The cam is located below the movable plate, and the rotation of the cam drives the movable plate to move up and down. A striking block is installed on the movable plate, and a gong that cooperates with the striking block is provided on the protective frame and above the striking block.
[0008] The knocking blocks are distributed on the upper surface of the movable plate at equal intervals.

DETAILED DESCRIPTION
[0019] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are not intended to limit the protection scope of the present invention.
[0020] like Figure 1 As shown, the utility model discloses a cigarette wire feeding pipeline leakage detection device, comprising a wire feeding connecting pipeline 1, on the surface of which an insulating heat-insulating gasket 2 is fixedly installed, and on the surface of which a flexible array temperature sensing unit 3 is fixedly installed.
[0021] like Figure 2 and Figure 4 As shown, a unit fixing ring 5 is installed on the outer surface of the flexible array temperature sensing unit 3, and a signal acquisition controller 6, a sound alarm 7 and a photoelectric alarm 8 are installed on the lower surface of the unit fixing ring 5. The input end of the signal acquisition controller 6 is electrically connected to the flexible array temperature sensing unit 3, and the output end of the signal acquisition controller 6 is electrically connected to the sound alarm 7 and the photoelectric alarm 8 respectively. The flexible array temperature sensing unit 3 integrates multiple small package thermistors on the flexible PCB, which are distributed axially and radially. When the wire feeding connection pipeline 1 leaks, gas will flow out from the interface leaking to form an airflow, and the airflow will take away the heat, causing the local temperature to drop. At this time, the temperature field is detected by the flexible array temperature sensing unit 3. After the temperature field reaches a certain deviation, the signal is transmitted to the signal acquisition controller 6. The signal acquisition controller 6 controls the sound alarm 7 and the photoelectric alarm 8 to work, so that the staff can find the location of the leak in time, which is convenient for maintenance.
[0022] In order to increase the monitoring flexibility of the utility model, the utility model also has a pipe connecting ring 4 connected between two adjacent wire feeding connecting pipes 1, and a fixed plate 9 is installed on the surface of the pipe connecting ring 4, and a motor 10 is fixedly installed on the surface of the fixed plate 9, and a cam 11 is installed on the output shaft of the motor 10. The power switch of the motor 10 is electrically connected to the output end of the signal acquisition controller 6. When the signal acquisition controller 6 receives the temperature field deviation, it also controls the motor 10 to work, driving the cam 11 to rotate. A protective frame 14 is installed on the surface of the fixed plate 9, and a movable plate 12 is slidably connected to the inside of the protective frame 14. A column 16 is fixedly installed on the inner wall of the protective frame 14, and the movable plate 12 passes through the column 16 and moves up and down along the column 16. The column 16 is an inverted L-shaped structure to prevent the movable plate 12 from falling off from the lower end of the column 16. Figure 3 As shown, the movable plate 12 is internally connected to a ball 17 for rotation, and the surface of the ball 17 is in contact with the surface of the column 16, so that the ball 17 allows the movable plate 12 to move only in the vertical direction. The cam 11 is located below the movable plate 12, and the rotation of the cam 11 drives the movable plate 12 to move up and down. The movable plate 12 is equipped with a knocking block 13, and the knocking blocks 13 are evenly spaced on the upper surface of the movable plate 12. A gong 15 that cooperates with the knocking block 13 is arranged on the protection frame 14 and above the knocking block 13.
[0023] After the temperature field reaches a certain deviation, the motor 10 also starts to work. At this time, the motor 10 drives the cam 11 to rotate. When the cam 11 rotates, the movable plate 12 loses its supporting force. At this time, the movable plate 12 drops under the action of its own gravity. After the cam 11 continues to rotate to its original position, the movable plate 12 is pushed up by the cam 11, and the column 16 makes the movable plate 12 move only in the vertical direction when it works, that is, repeating the above process, the movable plate 12 and the knocking block 13 make reciprocating linear motion in the vertical direction, and then the gong 15 will intermittently make a sound, that is, after the sound alarm 7, the gong 15 also plays the function of a sound alarm. The gong 15 provides a guarantee. When the sound alarm 7 and L are damaged, the device can still sound an alarm well.
[0024] In order to prevent dust from accumulating on the surfaces of the signal collector 6, the sound alarm 7, and the photoelectric alarm 8, the two ends of the movable plate 12 are respectively connected to the lower ends of two connecting rods 18, and the upper ends of the two connecting rods 18 are connected to the long plate 19, and the connecting rods 18 are symmetrically distributed about the center of the long plate 19. Figure 5As shown, three wiping plates 20 are connected to the long plate 19, and the three wiping plates 20 move up and down to wipe the surfaces of the signal acquisition controller 6, the sound alarm 7 and the photoelectric alarm 8 respectively. When the movable plate 12 makes a reciprocating linear motion in the vertical direction, it drives the connecting rod 18 and the long plate 19 to move synchronously. When the long plate 19 moves, it drives the wiping plates 20 to move synchronously, and then the wiping plates 20 can wipe the surfaces of the signal collector 6, the sound alarm 7, and the photoelectric alarm 8, so that the surfaces of the signal collector 6, the sound alarm 7, and the photoelectric alarm 8 will not accumulate a lot of dust, so that the signal collector 6, the sound alarm 7, and the photoelectric alarm 8 can work better.
[0025] The above are only preferred implementations of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
