For example, the utility model patent 201922085967.5, the utility model name is a filter rod / cigarette online sampling mechanism and a filter rod / cigarette sampling launching device. The patent completes sampling by rotating the inlet of the sampling tube to open and close the sampling tube from the conveying belt of the forming machine within a specified time, and then controls the end of the sampling tube to blow air, so that the cigarettes / filter rods in the sampling tube are blown into the launching tube, thereby achieving automatic sampling. However, the automatic sampling method has the following defects: (1) the cigarettes / filter rods are not easy to enter the sampling tube, and the sampling tube is easy to cause the blockage of the cigarettes / filter rods; (2) the cigarettes / filter rods rolled into the sampling tube may have phenomena such as damage of cigarette paper, falling of tobacco, and extrusion deformation of cigarettes / filter rods, thereby affecting the accuracy of the detection results.

[0031] See attached document Figure 1 As shown, the pull-out cigarette / filter rod online sampling and launching device of this embodiment includes a gripping mechanism 1, a pull-out receiving mechanism 2, a launching mechanism 3, and a reversing mechanism 4.

[0032] Please refer to the appendix. Figure 2 As shown, in this embodiment, the gripping mechanism 1 is located above the cigarette / filter rod transfer belt. It includes a gripper 11, a first power mechanism that drives the gripper 11 to move up and down, and a positive and negative pressure mechanism for sucking up and releasing the cigarette / filter rod 10. Specifically, the first power mechanism includes a first drive motor 12, a first belt 13, a first belt pulley 14, a vertical guide rail 15, and a gripping arm 16. A slider is provided on the vertical guide rail 15, and the slider is connected to the upper part of the gripping arm 16. The lower part of the gripping arm 16 is connected to the gripper 11, and the upper part of the gripping arm 16 is also connected to the first belt 13 through a belt connector 17. The first belt 13 connects the drive wheel of the first drive motor 12 and the first belt pulley 14. Under the drive of the first drive motor 12, the first belt 13 drives the gripping arm 16 to slide up and down along the vertical guide rail 15, thereby realizing the up and down movement of the gripper 11.

[0033] The vertical guide rail 15 is equipped with two sliders, both of which are fixedly connected to the gripper arm 16 to ensure that the gripper arm 16 is always in a vertical state.

[0034] The gripper 11 adopts a hollow pipe structure communicated with the positive and negative pressure mechanism, the bottom of the gripper 11 is provided with a circular arc groove 18 matched with the outer periphery of the cigarette / filter stick 10, air holes are formed on the circular arc groove 18, the upper part of the hollow pipe structure is communicated with the positive and negative pressure mechanism through an air pipe plug 19, and the air holes are communicated with the positive and negative pressure mechanism to realize suction and release of the cigarette / filter stick 10. That is, when the gripper 11 needs to grab the cigarette / filter stick 10, the first driving motor 12 drives the gripper 11 to move downward to above the cigarette / filter stick conveying belt, and then the negative pressure system of the positive and negative pressure mechanism is started, and the cigarette / filter stick is adsorbed through the negative pressure of the air holes; at this time, the first driving motor 12 is reversed to drive the gripper 11 and the cigarette / filter stick 10 to move upward to above the pull-out type material receiving mechanism.

Specifically, the first end of the material receiving pipe 21 is provided with a sliding end plate 28, and the two sides of the sliding end plate 28 are connected with the second power mechanism for driving the material receiving pipe 21 to realize horizontal pulling action. The second power mechanism includes a second driving motor 22, a second belt 23, a second belt fixed wheel 24, horizontal guide rails 25 and connecting plates 26. The horizontal guide rails 25 include two, and the two horizontal guide rails 25 are arranged in parallel and are each provided with a sliding block 27. The sliding blocks 27 are respectively connected with the connecting plates 26, and the two connecting plates 26 are respectively connected with the two sides of the sliding end plate 28. One of the connecting plates 26 is further connected with the second belt 23 through a belt connecting piece 29. The second belt 23 is connected with the driving wheel of the second driving motor 22 and the second belt fixed wheel 24, so that the second belt 23 is driven by the second driving motor 22 to drive the sliding end plate 28 to slide along the horizontal guide rails 25, thereby realizing stretching and retracting of the material receiving pipe 21.

[0036] In the embodiment, the space between the two horizontal guide rails 25 is used for the gripper 11 to move up and down. When the material receiving pipe 21 is retracted under the driving of the second power mechanism, it provides a space for the gripper 11 to move up and down. When the material receiving pipe 21 is stretched under the driving of the second power mechanism, it is located below the gripper 11 in the upper position, and is used to receive the cigarette / filter stick released by the gripper 11.

The launching cavity 31 adopts a cavity structure with two open ends, and a first port of the launching cavity 31 is provided for inserting a second end of the material receiving conduit 21. A sealing ring 33 is arranged at the first port of the launching cavity 31, and a sealing cover 34 is arranged on the sliding end plate 28 and cooperates with the sealing ring 33, so as to form a seal of the first port of the launching cavity 31 when the material receiving conduit 21 completely enters the launching cavity 31. A through gas path 35 is further arranged in the sliding end plate 28 and communicates with the material receiving conduit 21, and the other end of the through gas path 35 is connected with the high-pressure gas path 32 through a gas pipe plug 36. Then, the cigarette / filter rod 10 on the material receiving conduit 21 is launched from the second port of the launching cavity 31 under the action of the high-pressure gas source.

[0038] More specifically, the sealing ring 33 adopts a V-shaped sealing ring, and is fixed at the first port of the launching cavity 31 through a pressing sheet 37. An annular protrusion 38 is arranged on the outer edge of the sealing cover 34, and the annular protrusion 38 matches a V-shaped groove of the V-shaped sealing ring, so as to achieve the reliability of the seal.

The arc-shaped hollow pipe 41 is sealingly connected with the second end of the launching cavity 31, and the two ends of the arc-shaped hollow pipe 41 form a 90-degree turning angle. Of course, other turning angles can be set according to actual conditions. The direction changing mechanism 4 can realize reliable transmission of more than one hundred meters under the action of high-pressure gas.
