Can be divided into special filter sticks with the functions of enhancing and reducing harm and special filter sticks with the function of flavoring according to functions. The special filter stick with the function of enhancing and reducing harm comprises an active carbon composite filter stick, a particle composite filter stick, a groove filter stick and the like; the groove filter stick is a special filter stick made by wrapping cellulose diacetate tows by groove cellulose paper with a special structure, smoke is continuously changed transversely or obliquely in the filter stick under the action of the groove, and the probability of being intercepted by the cellulose diacetate tows is increased, so that the aim of reducing harm is fulfilled.

In order to ensure the quality of the filter stick, the roundness, the circumference and the hardness of a plurality of positions on the filter stick need to be detected so as to judge whether the quality of the filter stick meets the standard. At present, a comprehensive test bench is generally adopted to detect filter rods, for example: the comprehensive test platform of Europe and beauty and the comprehensive test platform of Ruitou technology. A detection head, a sliding rail and a sliding table capable of sliding on the sliding rail are arranged in the comprehensive test platform.

In order to ensure the accuracy of the detection result, the same position on the filter stick needs to be detected for multiple times, and a certain time interval exists between two adjacent detections; in the process, an operator needs to ensure that the detection environment of each detection performed on the same position is the same and the detection positions are consistent, so that the detection accuracy is improved; therefore, a great deal of time is consumed by the operator to adjust the detection position of the filter stick, so as to ensure that the actual detection position of the filter stick corresponding to the detection head is the same as the preset detection position in each detection. However, even in this case, the conventional filter rod detection method still tends to cause a problem of inaccurate detection results.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the problems that the conventional filter stick detection mode consumes large amount of manual labor and is easy to generate inaccurate detection results. The utility model provides a positioning rod for checking the detection position of a filter stick, which can simplify the detection steps, reduce the amount of manual labor and enhance the accuracy of the detection result of the filter stick.

The length and the diameter of the positioning rod are consistent with those of the filter stick to be detected, and the positioning rod is a simulation model of the filter stick and is used for verifying the detection position of the filter stick before the filter stick is detected. When the parameters of a certain position on the filter stick need to be checked, before the filter stick is detected each time, the positioning rod is placed in the comprehensive test bench, one end of the positioning rod is abutted against the sliding table, and then the sliding table is slid to enable the sliding table to push the positioning rod to move along the axis direction of the positioning rod.

The special filter stick is a filter stick which is manufactured by adopting a special filter stick forming process through the working procedures of processing, rolling, slitting and the like and has a special effect on cigarette smoke. Can be divided into special filter sticks with the functions of enhancing and reducing harm and special filter sticks with the function of flavoring according to functions.

In order to ensure the quality of the filter stick, the roundness, the circumference and the hardness of a plurality of positions on the filter stick need to be detected so as to judge whether the quality of the filter stick meets the standard. At present, a comprehensive test bench is generally adopted to detect filter rods, for example: the comprehensive test platform of Europe and beauty and the comprehensive test platform of Ruitou technology. The comprehensive test bench is internally provided with a test head, a slide rail 1 and a slide table 2 which can slide on the slide rail 1. The detection head comprises a laser detection head 3 and a hardness detection head 4, and the laser detection head 3 detects the roundness and the circumference of the filter stick 5 by emitting laser as shown in figure 1; the hardness detecting head 4 detects the hardness of the filter rod 5 by pressing the filter rod 5, as shown in fig. 2.
Before the filter stick 5 is detected, the position of the filter stick 5 needs to be adjusted so that the detection position of the filter stick 5 is aligned with the detection head. The existing way of adjusting the position of the filter stick 5 is: the sliding table 2 slides along the sliding rail 1, and the sliding table 2 pushes one end of the filter stick 5 to enable the filter stick 5 to move along the axial direction of the filter stick 5 so as to adjust the position of the filter stick 5; when the detection position of the filter stick 5 is aligned with the detection head, the sliding table 2 stops running, and then the detection head detects each parameter on the detection position. The accuracy of the test results is important and directly affects the probability that the product is rejected. In order to ensure the accuracy of the detection result, the same position on the filter stick 5 needs to be detected for multiple times, and a certain time interval exists between two adjacent detections; in the process, an operator needs to ensure that the detection environment of each detection performed on the same position is the same and the detection positions are consistent, so that the detection accuracy is improved; therefore, the operator consumes a lot of time to adjust the detection position of the filter rod 5 to ensure that the actual detection position of the filter rod 5 corresponding to the detection head is the same as the preset detection position in each detection. However, even in this case, the conventional filter rod 5 detection method is still prone to cause a problem of inaccurate detection results.
In order to solve the above technical problems, the inventors have found that the main reasons that the conventional filter stick 5 detection method is prone to generating inaccurate detection results are: in the existing detection mode of the filter stick 5, the same position on the filter stick 5 needs to be detected for multiple times, and a certain time interval exists between two adjacent detections; in the interval time, other detection positions of the filter rod 5 may be detected, so that the sliding table 2 is difficult to accurately return to the previous position after moving, and in multiple detections at the same detection position, a deviation exists between the actual detection position on the filter rod 5 corresponding to the detection head and the preset detection position, so that the consistency of the detection environment is damaged, and the detection result is inaccurate.
The positioning rod for verifying the detection position of the filter stick can simplify the detection steps, reduce the amount of manual labor and enhance the accuracy of the detection result of the filter stick 5.
To make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

When the detection head is aligned to the mark corresponding to the preset detection position on the positioning rod 6, the sliding table 2 and the positioning rod 6 stop running, then the positioning rod 6 is manually taken out from the comprehensive test table, and then the filter stick 5 is put in, so that the end part of the filter stick 5 is abutted to the sliding table 2, and the position on the filter stick 5 aligned to the detection head is the preset detection position. Therefore, the detection position of the filter stick 5 is verified by the positioning rod 6, so that the actual detection position of the filter stick 5 aligned by the detection head is the same as the preset detection position in each detection of the filter stick 5, the consistency of the detection environment can be further ensured, and the accuracy of the detection result is enhanced.
