Description

Technical Field

[0001] The utility model relates to the technical field of cigarette experimental equipment, in particular to a cigarette empty tube docking system. Background Art

[0002] In the process of cigarette production, smokers' satisfaction and comfort need to be considered while ensuring the safety of tobacco products. Studies have shown that the intrinsic qualities of cigarettes, such as the proportion of tobacco product ingredients, tobacco filling density, and filling uniformity, have an impact on the aroma quality and the release of harmful components in smoke. Therefore, in order to improve the intrinsic quality of cigarettes, laboratory personnel of tobacco companies will change the proportion of tobacco products and develop new formula tobacco products. When developing new formula tobacco products, it is necessary to prepare cigarettes with good proportions of formula tobacco into cigarettes for smoking aroma testing. However, since it is an experimental test sample, the amount of formula tobacco is small, and it is impossible to prepare formula cigarettes on the cigarette production line. At present, most laboratory personnel manually fill formula tobacco into empty cigarette cylinders to obtain formula cigarettes, with extremely low filling efficiency and uncontrollable filling density. In order to obtain formula cigarettes more conveniently, some laboratory personnel will use some small cigarette machines on the market to fill cigarette empty cylinders with cigarettes. Before a small cigarette making machine is filled with cigarettes, it is necessary to first connect the empty cigarette tube with the cigarette filling structure. However, when existing small cigarette making machines connect the empty cigarette tube with the cigarette filling structure, the empty cigarette tube and the cigarette filling structure often come into contact and rub against each other, causing the end of the empty cigarette tube to wrinkle and be damaged, resulting in defects in the finished formula cigarettes and affecting the smoking aroma test.

[0003] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the invention

[0004] The purpose of the utility model is to address the deficiencies of the prior art and thus provide a cigarette empty tube docking system. The utility model can avoid contact friction when the cigarette empty tube and the cigarette filling introduction tube are docked, prevent wrinkling and damage to the cigarette empty tube port, improve the quality of cigarette empty tube docking, ensure the quality of the finished formula cigarette products, and facilitate smoking aroma testing.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a cigarette empty tube docking system, including a cigarette empty tube bearing platform, a first linear reciprocating drive mechanism, a cigarette filling introduction tube, a cigarette filling module and a second linear reciprocating drive mechanism, the cigarette empty tube bearing platform is installed on the first linear reciprocating drive mechanism, the cigarette filling introduction tube is installed on the cigarette filling module and is located on a side close to the cigarette empty tube bearing platform, the cigarette filling module is installed on the second linear reciprocating drive mechanism, the cigarette empty tube is placed on the cigarette empty tube bearing platform, the cigarette empty tube and the cigarette filling introduction tube are at the same height and their axes are parallel to the movement direction of the first linear reciprocating drive mechanism, the movement direction of the second linear reciprocating drive mechanism is perpendicular to the movement direction of the first linear reciprocating drive mechanism, the inner diameter of the cigarette empty tube is greater than or equal to the outer diameter of the cigarette filling introduction tube, the end of the cigarette filling introduction tube close to the cigarette empty tube bearing platform is a beveled and pointed elliptical end face, and the projection of the major axis of the elliptical end face on the vertical plane of the cigarette filling introduction tube is parallel to the movement direction of the second linear reciprocating drive mechanism.

[0006] Based on the above, the first linear reciprocating drive mechanism is a linear module including a slide.

[0007] Based on the above, the cigarette empty tube support platform includes an empty tube transverse push plate and an empty tube placement plate. The bottom of the empty tube transverse push plate is fixedly connected to the upper surface of the slide table of the first linear reciprocating drive mechanism. The empty tube placement plate is fixedly connected to the top of the empty tube transverse push plate and extends horizontally toward the cigarette filling module. The cigarette empty tube is placed on the empty tube placement plate and the end of the cigarette empty tube close to the cigarette filling inlet pipe extends out of the side of the empty tube placement plate close to the cigarette filling inlet pipe.

[0008] Based on the above, a horizontally arranged cantilever plate is integrally formed on one side of the upper part of the empty tube transverse push plate close to the smoke filling inlet pipe, and the empty tube placement plate is fixedly connected to the cantilever plate.

[0009] Based on the above, a receiving groove for placing empty cigarette tubes is provided on the upper surface of the empty tube placement plate along the movement direction of the first linear reciprocating drive mechanism, and the center line of the receiving groove intersects with the movement trajectory of the cigarette filling inlet tube. The side of the receiving groove close to the cigarette filling inlet tube is open and the side away from the cigarette filling inlet tube is blocked.

[0010] Based on the above, the inner diameter of the containing groove is greater than or equal to the outer diameter of the empty cigarette tube, and the empty cigarette tube is placed in the containing groove.

[0011] Based on the above, the length of the receiving groove is smaller than that of the empty cigarette tube, one end of the empty cigarette tube close to the cigarette filling introduction tube extends out of the receiving groove for a distance, and the other end of the empty cigarette tube contacts the blocking side of the receiving groove.

[0012] Based on the above, the second linear reciprocating drive mechanism includes a base plate, a stepper motor, a linear guide, a drive disk, a sliding plate and a connecting rod. The stepper motor and the linear guide are fixedly installed on the base plate at intervals. The motor shaft of the stepper motor is perpendicular to the linear guide and parallel to the first linear reciprocating drive mechanism. The drive disk is fixedly installed on the motor shaft of the stepper motor, and the sliding plate is slidably installed on the linear guide.

The stepper motor, linear guide, drive disk, sliding plate and connecting rod constitute a crank-connecting rod slider mechanism, and the cigarette filling module is installed on the sliding plate.

[0013] The utility model has substantial characteristics and progress compared with the prior art. Specifically, the utility model drives the empty cigarette tube carrier to make linear motion through the first linear reciprocating drive mechanism, so that the empty cigarette tube carrier drives the empty cigarette tube to approach or move away from the filling cigarette introduction tube, and drives the filling cigarette module to make linear motion through the second linear reciprocating drive mechanism, so that the filling cigarette module drives the filling cigarette introduction tube to reciprocate and deviate. The end of the filling cigarette introduction tube close to the empty cigarette tube carrier is an obliquely cut and pointed elliptical end face. When the empty cigarette tube and the filling cigarette introduction tube are aligned, the cigarette filling module is driven to move the empty cigarette tube to the filling cigarette introduction tube. Align the tip of the filling cigarette introduction tube with the center of the empty cigarette tube, then bring the empty cigarette tube close to the filling cigarette introduction tube and cover it on the tip of the filling cigarette introduction tube to avoid contact friction when the empty cigarette tube and the filling cigarette introduction tube are connected, and prevent the end of the empty cigarette tube from wrinkling and damage. Then, offset the filling cigarette introduction tube to align the filling cigarette introduction tube with the center of the empty cigarette tube, and the empty cigarette tube continues to move toward the filling cigarette introduction tube until the filling cigarette introduction tube is completely covered, thereby improving the connection quality of the empty cigarette tube, ensuring the quality of the finished formula cigarette, and facilitating the smoking aroma test.
