[0035] The transmission assembly includes two pairs of roller frames 7, which are fixedly connected to both sides of the top of the measuring platform 3, and a motor 8 is installed on the roller frame 7. A transmission roller 9 is fixedly connected to the output shaft of the motor 8. The transmission roller 9 is located between the two pairs of roller frames 7, and a transmission belt 10 is drivingly connected between the two transmission rollers 9. The height of the transmission belt 10 is flush with the first light source 4. The transmission belt 10 can be supplemented with light from one side by the first light source 4 to provide brightness for the shooting of the first camera 15. The surface of the transmission belt 10 is respectively provided with a plurality of blocks 11 and positioning blocks 12. The transmission roller 9 can be driven by the driving motor 8 to move together with the transmission belt 10, the block 11 and the positioning block 12, so as to transmit the cigarette filter to be measured to the measuring position;

[0036] The first shooting assembly includes a first shooting frame 13, which is fixedly connected to the base 1, and a first mounting plate 14 is mounted on the top of the first shooting frame 13, and a first camera 15 is mounted on the first mounting plate 14;

[0037] The second shooting assembly includes a second shooting frame 16, which is fixedly connected to the top inner wall of the base 1, and an electric telescopic rod 17 is installed at the bottom. The bottom end of the output shaft of the electric telescopic rod 17 is fixedly connected to a second mounting plate 18, and a second camera 19 is installed on the second mounting plate 18. By driving the electric telescopic rod 17, the second mounting plate 18 can be driven to move up and down together with the second camera 19, so as to adjust the shooting height of the second camera 19, so as to obtain a corresponding complete picture according to the different lengths of the filter tip.

[0038] Among them, the top of the measuring platform 3 is an inclined end surface, and its height close to the first shooting frame 13 is less than the height close to the fixed frame 2. The first shooting frame 13 and the second shooting frame 16 are both inclined and respectively located directly above and on one side of the measuring platform 3, and the top of the first shooting frame 13 and the bottom of the second shooting frame 16 are both parallel to the top surface of the measuring platform 3. The center of the first camera 15 is coaxial with the center of the stopper 11. The first camera 15 can be used to shoot from the circular side of the cigarette filter to obtain a diameter hole number image of the filter. The second camera 19 can be used to shoot from the radial top of the cigarette filter to obtain a length image of the filter. The first camera 15 and the second camera 19 are both externally connected to a visual recognition system. The visual recognition system can identify and analyze the collected images, thereby measuring the required filter diameter hole number and length. The visual recognition system belongs to the existing conventional technology in the computer field. Since its specific structure and working principle do not belong to the protection scope of the present technical method, it will not be described in detail.

[0039] Among them, the conveyor belt 10 is located directly above the installation groove 5 and directly below the second camera 19, and the conveyor belt 10 adopts a light-transmitting design. When the conveyor belt 10 drives the cigarette filter to move directly above the installation groove 5, the second light source 6 in the installation groove 5 can be used to fill the conveyor belt 10 from the bottom to provide brightness for the shooting of the second camera 19.

[0040] Among them, the number of blocks 11 and positioning blocks 12 is the same, and they are equidistantly distributed along the surface of the conveyor belt 10. The center of each block 11 corresponds to the center of each positioning block 12 one by one, and one side of each positioning block 12 is attached to the side wall of the corresponding block 11. The block 11 and the positioning block 12 can be made of soft rubber or silicone material and fixed to the conveyor belt 10 by glue or other means.

[0041] Among them, each stopper 11 has a through hole 20 on its surface, and each positioning block 12 has a positioning groove 21 on its top surface. The through hole 20 is a circular hole, and the positioning groove 21 is an arc-shaped groove. The through holes 20 and the positioning grooves 21 have the same number and diameter, and the bottom height of each through hole 20 is flush with the bottom height of each positioning groove 21. The top and bottom hole walls of each through hole 20 are fixedly connected with a protrusion 28. Since the top of the measuring platform 3 is an inclined end face, when measuring the cigarette filter, the filter can slide along the positioning groove 21 to one side of the stopper 11 under the action of gravity until one end of the filter is aligned and inserted. To the corresponding through hole 20, at this time, the filter tip is attached to the side wall of the protrusion 28 in the through hole 20, and the combined effect of the through hole 20 and the protrusion 28 can make all cigarette filter tips to be measured in the same batch remain flush, thereby avoiding measurement errors, and there is no need to manually align them one by one, which not only effectively improves work efficiency, but also reduces labor intensity. The aperture of the through hole 20 is designed to be larger than the maximum filter tip diameter in the same batch, and the spacing between the protrusions 28 is designed to be smaller than the minimum filter tip diameter in the same batch, so as to ensure that all cigarette filter tips can enter the through hole 20 and will not leak out of the through hole 20.

[0042] Among them, a pair of threaded holes 22 are provided on the surface of the first mounting plate 14, and bolts 23 matching therewith are threadedly connected inside the threaded holes 22, and nuts 24 matching therewith are threadedly connected on the bolts 23. An adjustment hole 25 is provided on the top of the first shooting frame 13, and the adjustment hole 25 is a square hole structure, and its width is equal to the aperture of the threaded hole 22. The first mounting plate 14 can drive the first camera 15 to move horizontally along the first shooting frame 13 to adjust the shooting position of the first camera 15, so as to obtain a corresponding complete picture according to the different diameters of the filter tip. When the bolt 23 in the threaded hole 22 is tightened, the end of the bolt 23 can pass through the adjustment hole 25. At this time, the nut 24 is threadedly connected to the bolt 23 and tightened. The first mounting plate 14 can be locked by the mutual cooperation between the bolt 23, the threaded hole 22 and the adjustment hole 25, so as to fix the installation position of the first camera 15.

[0043] Among them, a pair of guide blocks 26 are fixedly connected to the top of the first mounting plate 14. The guide blocks 26 are rectangular block structures and are respectively located on both sides of the pair of threaded holes 22. A pair of guide grooves 27 are opened on the top surface of the first shooting frame 13. The guide grooves 27 are rectangular groove structures and are respectively located on both sides of the adjustment hole 25. The groove width of the guide grooves 27 is equal to the width of the guide blocks 26. The center of each guide groove 27 corresponds to the center of each guide block 26 one by one. The guide blocks 26 can be aligned and fit in the corresponding guide grooves 27. The mutual cooperation between the guide blocks 26 and the guide grooves 27 can play a guiding and limiting role to avoid the position of the first mounting plate 14 from being offset, thereby facilitating the rapid positioning and fixing of the first mounting plate 14.

[0044] The circuits, electronic components and chip modules involved in the utility model are all existing technologies and can be fully implemented by those skilled in the art. Needless to say, the content protected by the utility model does not involve improvements to software and methods.

[0045] The standard parts used in the application documents can all be purchased from the market. All the components in this application document can be customized according to the description in the specification and drawings. The specific connection methods of each part adopt mature conventional means such as bolts, rivets, welding, etc. in the prior art. Machinery, parts and equipment all adopt conventional models in the prior art. The electrical components appearing in this article are all electrically connected to the external main controller and 220V AC power, and the main controller can be a conventional known device that controls the LED lamp body, etc.

[0046] The working principle of the utility model is:

[0047] When the utility model is used, firstly, the electrical components in the measuring instrument device are connected to the control switch and the power supply through the wires, then the first light source 4 and the second light source 6 are turned on respectively, and the cigarette filter to be measured is placed on the conveyor belt 10. Since the top of the measuring platform 3 is an inclined end face, the filter can slide along the positioning groove 21 to the side of the block 11 under the action of gravity until one end of the filter is aligned and inserted into the corresponding through hole 20. At this time, the filter fits the side wall of the protrusion 28 in the through hole 20. Through the joint action of the through hole 20 and the protrusion 28, all the cigarette filter to be measured in the same batch can be kept flush, thereby avoiding measurement errors, and there is no need to align them one by one manually, which not only effectively improves work efficiency, but also reduces labor intensity. When it is necessary to measure the cigarette filter, the driving motor 8 drives the conveyor roller 9 to move together with the conveyor belt 10, the block 11 and the positioning block 12 until the cigarette filter to be measured is transferred to the measuring position and stops. Then, the first camera 15 and the second camera 19 can respectively detect the circular shape of the filter. The first camera 15 and the second camera 19 are both connected to an external visual recognition system, through which the collected images can be recognized and analyzed, so as to measure the required parameters such as the number of holes and length of the filter. The visual recognition system belongs to the existing conventional technology in the computer field. Since its specific structure and working principle do not belong to the protection scope of the present technical method, they are not described in detail. By driving the electric telescopic rod 17, the second mounting plate 18 can be driven to move up and down together with the second camera 19, so as to adjust the shooting height of the second camera 19, so as to obtain a corresponding complete picture according to the different lengths of the filter. The first mounting plate 14 can drive the first camera 15 to move horizontally along the first shooting frame 13, so as to adjust the shooting position of the first camera 15, so as to obtain a corresponding complete picture according to the different diameters of the filter, thereby effectively improving the accuracy of the measurement results. After that, the motor 8 is continued to be driven to drive the conveyor belt 10 to move, and the next cigarette filter can be measured.
