Description

Technical Field

[0001] The utility model belongs to the technical field of filter rod online sampling and detection, and in particular relates to a conveying device for filter rod sampling. Background Art

[0002] Filter rods are an important component of cigarettes and are mainly used to filter smoke particulate matter, thereby reducing tar and reducing harm. Therefore, during the production process of filter rods, the quality of filter rods must be strictly controlled. The quality of filter rods is mainly reflected by the physical index parameters of the filter rods (such as circumference, roundness, suction resistance, weight, etc.).

[0003] In order to measure the physical index parameters of the filter rod, the currently commonly used filter rod automatic sampling device grabs the filter rod through a mechanical gripper or negative pressure suction, which is installed in the filter rod conveying channel of the forming machine. The filter rods obtained by the above two grabbing methods are conveyed through the conveying pipeline to the comprehensive test platform (abbreviated as QTM in English) in the filter rod inspection room for automatic measurement of physical indicators. In the actual production process, filter rods are usually measured in groups of 10 (different tobacco companies have different requirements), and the filter rods produced by the same forming machine are not sampled continuously and uninterruptedly, but sampled at certain time intervals. However, the existing filter rod sampling device of one QTM docking a forming machine leads to an increase in the number of QTMs and the cost of filter rod detection, and also reduces the utilization rate of QTM. Therefore, how to design a conveying device for filter rod sampling to reduce the number of comprehensive test platforms and improve the utilization rate of comprehensive test platforms has become a technical problem that technicians in this field urgently need to solve.

[0021] In order to enable those skilled in the art to better understand the technical solution of the utility model, the solution will be further described in detail below in conjunction with specific embodiments.

[0022] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a conveying device for filter rod sampling, which includes a collecting barrel and a cover plate 21, wherein the cover plate 21 is connected to the upper end surface of the collecting barrel, and the cover plate 21 is used to seal the upper port of the collecting barrel; at least two filter rod inlet pipes 31 are arranged on the cover plate 21, and each of the filter rod inlet pipes 31 is respectively connected to the filter rod conveying pipeline of each filter rod sampling device; the cover plate 21 is also provided with an air inlet pipe 41 for connecting to the air supply system; the collecting barrel is a detachable split structure, and the lower port of the collecting barrel is the filter rod outlet 14.

[0023] The filter rod sampling conveying device provided in the embodiment of the utility model, when in use, connects each filter rod inlet pipe 31 to the filter rod conveying pipeline of the filter rod sampling device of each molding machine in a one-to-one correspondence, so that the filter rod sampling device of each molding machine can convey the filter rod to the filter rod inlet pipe connected thereto through its own filter rod conveying pipeline at different times, and then the filter rod enters the collecting cylinder, and compressed air is introduced into the collecting cylinder through the air inlet pipe 41, so that the filter rod can slide out of the filter rod outlet 14 more smoothly and enter the filter rod receiving device, and then enter the comprehensive test platform. It can be seen that the utility model enables the same comprehensive test platform to simultaneously dock with the filter rod sampling devices of at least two molding machines, thereby effectively reducing the number of comprehensive test platforms, improving the utilization rate of the comprehensive test platforms, and reducing the cost of filter rod detection.

[0024] Furthermore, the collecting barrel comprises an inverted cone section 11 and a cylindrical section 12 which are sequentially connected from top to bottom, and the diameter of the cylindrical section 12 is the same as the diameter of the lower end of the inverted cone section 11, so as to facilitate the filter rod to enter the collecting barrel.

[0025] In an embodiment provided by the utility model, the left side of the inverted conical section 11 has a notch 15, and an arc plate 13 for covering the notch and forming an inverted conical structure together with the right side of the inverted conical section, and the arc plate 13 is detachably connected to the right side of the inverted conical section. With this solution, the collection tube is a detachable split structure, so that it is convenient to clean it when the collection tube is blocked.

[0026] Furthermore, a first connecting ring 51 is provided on the outer wall of the arc-shaped plate 13, a second connecting ring 52 is provided on the right outer wall of the inverted conical section, bolts 53 are provided at both ends of the first connecting ring, and through holes 54 opposite to the bolts are provided at both ends of the second connecting ring. With this solution, a detachable connection between the arc-shaped plate and the right side of the inverted conical section is conveniently realized. During installation, two bolts are respectively passed through the two through holes to match with nuts, and then tightened.

[0027] Specifically, the through hole 54 is a threaded hole, so that the connection between the first connecting ring and the second connecting ring is more firm and reliable.

[0028] Preferably, the first connecting ring 51 and the second connecting ring 52 are magnetically attracted to each other, so that the connection between the first connecting ring and the second connecting ring is more convenient, and the connection firmness between the first connecting ring and the second connecting ring can be further improved.

[0029] Specifically, each filter rod inlet pipe 31 is connected to each filter rod delivery pipeline through a quick-plug connector structure, so that when the collection tube is blocked, the filter rod inlet pipe and the filter rod delivery pipeline can be quickly separated. The air inlet pipe can also be connected to the air supply system through a quick-plug connector structure, so as to facilitate quick connection. Preferably, the arc plate is welded to the first connecting ring, and the second connecting ring is welded to the right outer wall of the inverted cone section.

[0030] It is understandable that the specific number of filter rod inlet pipes provided on the cover plate 21 can be determined according to the sampling interval of each forming machine to prevent filter rods generated by different forming machines from entering the collecting cylinder at the same time. When the filter rods pass through the collecting cylinder smoothly and are transported from the filter rod outlet to the filter rod receiving device, when the number of filter rods in the filter rod receiving device reaches 10, these 10 filter rods enter the QTM as a group for measurement.

[0031] In another embodiment provided by the utility model, the collecting cylinder comprises a left half cylinder and a right half cylinder, and the left half cylinder is detachably connected to the right half cylinder. Preferably, the left half cylinder and the right half cylinder are also detachably connected by using the first connecting ring and the second connecting ring.

[0032] Taking the two filter rod inlet pipes 31 provided on the cover plate 21 as an example, during installation, the two filter rod inlet pipes 31 are respectively connected to the filter rod conveying pipes of the filter rod sampling devices of the two forming machines, the air inlet pipe is connected to the air supply system, and the filter rod outlet is connected to the filter rod receiving device. Only one of the two filter rod sampling devices respectively connected to the two filter rod inlet pipes works at the same time to avoid the mixing of filter rods produced by different forming machines, so that the two forming machines can be connected to the same QTM, thereby facilitating the corresponding grouping measurement of filter rods produced by different forming machines.

[0033] The utility model has the advantages of simple structure, convenient maintenance and good adaptability and popularization.

[0034] The above are only preferred implementation modes of the present invention. It should be pointed out that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. Moreover, after reading the contents of the present invention, relevant technical personnel in the field can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.
