DETAILED DESCRIPTION

[0025] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments:

[0026] As Figures 1-7 shown, a strip package appearance detection device of the present invention includes a frame 1, a detection device, a rejection device, and a conveying device. The conveying device includes a first conveying device 31, a second conveying device 32, and a third conveying device 33. The first conveying device 31 includes a first conveyor belt 311, a first driving roller 312, and a first driven roller 313 respectively installed at both ends of the first conveyor belt 311. Installation grooves 12 are provided on both sides of the frame 1. A housing 5 is fixedly installed outside the installation grooves 12 by bolts. Through holes are provided on the housing 5. Both ends of the first driving roller 312 are rotatably installed in the through holes through bearings, and both ends of the first driven roller 313 are rotatably installed on the frame 1 through bearings. A driving motor 61 is provided on one side of the frame 1. The first driving roller 312 is fixedly connected to the output shaft of the driving motor 61. The driving motor 61 rotates the first driving roller 312, driving the first conveyor belt 311 to move. Thus, the strip package 4 on the first conveyor belt 311 moves along with the first conveyor belt 311.

[0027] Both the second conveying device 32 and the third conveying device 33 include a second conveyor belt 341, a second driving roller 342, and a second driven roller 343 respectively installed at both ends of the second conveyor belt 341. The second driving roller 342 and the second driven roller 343 are both rotatably installed in the installation grooves 12 through bearings. The second driving roller 342 is located above the first driving roller 312. A first bevel gear 314 is provided on the first driving roller 312 at the position of the second driving roller 342, and a second bevel gear 344 is provided on the second driving roller 342. Through the meshing of the first bevel gear 314 and the second bevel gear 344, when the driving motor 61 drives the first driving roller 312 to rotate, the second driving roller 342 is driven to rotate. Thus, both the first conveyor belt 311 and the second conveyor belt 341 move, and the first conveying device 31, the second conveying device 32, and the third conveying device 33 synchronously convey the strip packages.

[0028] A guide plate 35 is installed at one end of the first conveying device 31. The strip package 4 enters the first conveyor belt 311 of the first conveying device 31 through the guide plate 35. The conveying surface of the strip package 4 is in contact with the first conveyor belt 311 in the first conveying device 31. A support block 36 is provided inside the second conveyor belt 341. The support block 36 is fixedly connected to the bottom surface of the installation groove 12. The support block 36 supports the second conveyor belt 341, enabling the second conveyor belt 341 to ensure that the strip package 4 is clamped and transported forward.

[0029] When the first conveyor 31 conveys the strip pack 4 to the second conveyor 32 and the third conveyor 33, the end surfaces of the first conveyor belts 311 on the second conveyor 32 and the third conveyor 33 guide the strip pack 4, so that the strip pack 4 enters between the second conveyor 32 and the third conveyor 33. The second conveyor 32 and the third conveyor 33 clamp the strip pack 4 for conveyance, so that the conveying surface of the strip pack 4 on the first conveyor, i.e., the lower surface, is exposed.

[0030] The detection device includes a first detection device 21 and a second detection device 22. The first detection device 21 includes a mounting seat 211, on which a first camera group 212, a second camera group 213 and a third camera 214 are mounted. The first camera group 212 and the second camera group 213 each include two cameras, which are mounted opposite to each other. The first camera group 212 is used to take pictures of the front and back sides of the bag 4, and the second camera group 213 is used to take pictures of the sides of the bag 4. The third camera 214 is used to take pictures of the top surface of the bag 4. The second detection device 22 is mounted at the bottom of the area between the second conveying device 32 and the third conveying device 33. The second detection device includes a fourth camera 215, which is used to take pictures of the bottom surface of the bag 4.

[0031] Both sides of the top of the frame 1 are integrally formed with mounting blocks 11, and the mounting seat 211 is rotatably mounted between the two mounting blocks 11. A rotating shaft 22 is fixedly connected inside the mounting seat 211, and the rotating shaft 22 is rotatably connected to the mounting blocks 11 on both sides. A clamping groove 221 is provided at the outer end of the mounting block 11. A housing 13 is integrally formed on the mounting block 11, and a card body 7 is slidably arranged inside the housing 13. Both sides of the top surface of the card body 7 are integrally formed with clamping columns 71, and the clamping columns 71 are inserted into the clamping groove 221 to prevent the rotating shaft 22 from rotating. A column 131 is integrally formed on the bottom surface of the housing 13, and a spring 132 is sleeved on the column 131. One end of the spring 132 is connected to the bottom surface of the housing 13, and the other end is connected to the bottom surface of the card body 7. A toggle block 72 is integrally formed outside the card body 7, and an anti-slip pattern 721 is provided on the toggle block 72. When the first detection device needs to be repaired, the card body 7 can be moved downward by pressing the toggle block 72, thereby disengaging the card column 71 from the card slot 221, and then rotating the mounting seat 211 by 180 degrees so that the internal components are directly above, which is convenient for maintenance. Then, the toggle block 72 is released to allow the card column 71 to be inserted into the card slot 221 again, preventing the mounting seat 211 from rotating.

[0032] The rejection device is installed between the second conveying device 32 and the third conveying device 33. The rejection device includes a mounting plate 81, a rejection plate 82, a knocker 83 and a processor 84. The knocker 83 is fixedly installed on the mounting plate 81. A slot is opened on the mounting plate 81. The rejection plate 82 is rotatably connected in the slot through a torsion spring. The knocking end of the knocker 83 is located above the rejection plate 82. The knocker 83, the first camera group 212, the second camera group 213, the third camera 214 and the fourth camera 215 are all electrically connected to the processor 84. After the first camera group 212, the second camera group 213, the third camera 214 and the fourth camera 215 take pictures of the surface of the strip package 4, the pictures are transmitted to the processor 84 for analysis and detection whether they are qualified. If they are unqualified, when it is calculated that the unqualified strip package 4 is located at the rejection device, the processor 84 controls the knocker 83 to work. The knocker 83 can be a telescopic device commonly used in the prior art, such as a cylinder, an electric push rod, etc. The telescopic device knocks the reject plate 82 downward, and the reject plate 82 rejects the unqualified strip packages 4.

[0033] The present invention provides a strip pack appearance inspection device. During inspection, the strip pack 4 first passes through the first conveying device 31, and the first camera group 212, the second camera group 213 and the third camera 214 respectively take photos of the front, back, two sides and the top of the strip pack 4, and transmit the taken photos to the processor 84. Subsequently, the strip pack 4 is transported between the second conveying device 32 and the third conveying device 33, and the bottom surface of the strip pack 4 is photographed by the fourth camera 215 at the bottom, and the photographed photos are transmitted to the processor 84. The processor 84 analyzes the pictures and detects whether they are qualified. If they are unqualified, when it is calculated that the unqualified strip pack 4 is located at the rejection device, the processor 84 controls the knocker 83 to work, and the knocker 83 knocks the rejection plate 82 downward, and the rejection plate 82 rejects the unqualified strip pack 4. Compared with the prior art, the present invention solves the problem that the prior art has a detection blind spot on the transport surface and cannot achieve comprehensive detection of tobacco strips.

[0034] When the present invention is repaired, the card body 7 can be moved downward by pressing the toggle block 72, thereby disengaging the card column 71 from the card slot 221, and then rotating the mounting seat 211 by 180 degrees, so that the internal components are directly above, which is convenient for maintenance. Then, the toggle block 72 is released, so that the card column 71 is again inserted into the card slot 221, preventing the mounting seat 211 from rotating.
