[0002] In the current filter rod forming technology of the cigarette industry, the filter rod forming machine is one of the filter rod production equipment with the highest automation and processing capabilities in China. Among them, the accelerator transfer process is a very important process in the filter rod transfer process. The accelerator absorbs the cut filter rods through the negative pressure suction holes distributed on the outer circumference of the acceleration wheel and accelerates the delivery to the receiving drum.

[0003] In the actual production process, since there will inevitably be residues such as glue scale and broken wires on the surface of the filter rod after cutting, the acceleration wheel will adsorb the filter rod for a long time, which may easily cause the negative pressure channel in the accelerator to be blocked, resulting in equipment failures such as filter rod running, and the accelerator negative pressure channel needs to be cleaned periodically.

[0004] The acceleration wheel has only a negative pressure suction hole connected to the outside. It is difficult to clean the glue scale and broken wires by cleaning the negative pressure channel through the negative pressure suction hole. Therefore, cleaning the accelerator requires disassembling the entire accelerator bracket and the acceleration wheel, which is labor-intensive and time-consuming, affecting the efficiency of the equipment. At the same time, the accelerator bracket and the acceleration wheel have high requirements for the alignment and installation accuracy. Improper installation may easily make the negative pressure channel insufficiently sealed, resulting in low filter rod transmission effect and reduced accelerator service life. Summary of the invention

[0005] The purpose of the present invention is to address the deficiencies of the above-mentioned prior art and to provide an acceleration wheel and an accelerator, which do not require the entire accelerator to be disassembled when cleaning the acceleration wheel, have high cleaning efficiency and will not affect the use effect and service life of the accelerator.

[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other arbitrarily without conflict.

[0023] Reference Figure 1 and Figure 2 As shown, the present invention provides an acceleration wheel, including an acceleration wheel body 1 and a plug 2, the acceleration wheel body 1 is a cylindrical structure, the interior of the acceleration wheel body 1 is hollow and a vacuum hole 4 is provided on the side wall of the acceleration wheel body 1, and a blowing hole 5 is provided on an end face of one side of the acceleration wheel body 1. The end face of the acceleration wheel body 1 refers to two circular faces parallel to both sides of the side wall of the acceleration wheel body 1 when the acceleration wheel body 1 is a cylindrical structure, and the plug 2 is detachably installed in the blowing hole 5.

[0024] In the acceleration wheel provided by the present invention, the acceleration wheel can be rotated by an external driving mechanism. During the rotation of the acceleration wheel, the filter rod is adsorbed through the vacuum hole 4 on the side wall to complete the filter rod transfer process.

[0025] During the filter rod transfer process, the remaining glue scale and broken wires on the filter rod will be absorbed into the acceleration wheel body 1 with the negative pressure at the vacuum hole 4. The direction of the negative pressure airflow on the acceleration wheel body 1 is always in the same direction. The long-term accumulation of glue scale and broken wires in one direction will gradually become compact and accumulate more and more. It is difficult to clean the accumulated glue scale and broken wires through the negative pressure airflow at the vacuum hole 4. In the acceleration wheel provided by the present invention, a blowing hole 5 is provided on the end face of the acceleration wheel body 1. When the glue scale and broken wires accumulated in the acceleration wheel body 1 are difficult to clean, air is blown inwardly through the blowing hole 5 through an air gun to blow away the dirt of the glue scale and broken wires, and then the blown-away glue scale and broken wires are sucked away through the negative pressure channel that generates the negative pressure airflow. When the glue scale and broken wires accumulated in the acceleration wheel body 1 are very compact and the airflow of the air gun cannot blow them away, a scraper can be extended into the blowing hole 5, and the glue scale and broken wires are scraped away by the scraper, and then the glue scale and broken wires are sucked away through the negative pressure channel in combination with the air gun and the negative pressure. And when the acceleration wheel is working normally, the blowing hole 5 can be closed by the plug 2, so that the acceleration wheel body 1 is in a closed state, and the plug 2 is opened only when cleaning is needed. The plug 2 can be a rubber plug 2 and also includes a sealing ring 3. The sealing ring 3 is installed between the plug 2 and the blowing hole 5 to seal the blowing hole 5.

[0026] As described above, the entire cleaning process does not require the acceleration wheel to be removed from the entire device, thereby avoiding low work efficiency caused by removing the acceleration wheel for cleaning, reducing the sealing performance of the negative pressure channel of the device and the service life of the entire device.

[0027] Furthermore, the number of the blowing hole 5 is at least one. In this embodiment, the number of the blowing hole 5 is one. The opening position of the blowing hole 5 is set according to the accumulation position of the adhesive scale and broken wire in the acceleration wheel in actual use, so as to facilitate the cleaning of the accumulated adhesive scale and broken wire. When the number of the blowing holes 5 is multiple, the multiple blowing holes 5 are distributed in a circle, wherein the circumferential distribution is also adapted to the cylindrical shape of the acceleration wheel, wherein the accumulated adhesive scale and broken wire are also accumulated in the circumferential direction, and the circumferential distribution is more convenient for cleaning the adhesive scale and broken wire.

[0028] Furthermore, the blowing hole 5 is located at the edge of the end face of the acceleration wheel body 1. During the rotation of the acceleration wheel body 1, the adhesive scale and broken wires adsorbed into the acceleration wheel body 1 will move and accumulate toward the edge inside the acceleration wheel body 1 under the action of the centrifugal force of the acceleration wheel body 1. The blowing hole 5 is located at the edge of the end face of the acceleration wheel body 1 so that the air gun can face the accumulated adhesive scale and broken wires when blowing air into the acceleration wheel body 1, thereby facilitating the cleaning of the adhesive scale and broken wires. At the same time, when the adhesive scale and broken wires are accumulated densely, the scraper can easily contact the adhesive scale and broken wires when it is extended into the blowing hole 5, thereby facilitating the cleaning of the adhesive scale and broken wires and improving the cleaning efficiency.

[0029] like Figure 3 and Figure 4 As shown in, the present invention also provides an accelerator, comprising a motor 7, a rotating shaft 8, a connecting block 9, a joint pipe 10 and the acceleration wheel as described above, wherein the opposite surface of the end surface of the acceleration wheel body 1 having the blowing hole 5 is an open surface, one end of the rotating shaft 8 is connected to the motor 7, and the other end of the rotating shaft 8 is connected to the inner side surface of the end surface of the acceleration wheel body 1 having the blowing hole 5; the connecting block 9 is installed between the motor 7 and the acceleration wheel body 1, the connecting block 9 is cylindrical, and the connecting block 9 is divided into an upper part 91 and a lower part 92 along its axial direction, the interior of the upper part 91 is hollow, and the end surface of the upper part 91 facing the acceleration wheel body 1 is an open surface, and the lower part 92 has a through hole, the rotating shaft 8 is rotatably penetrated in the through hole, and the outer side wall of the upper part 91 is in contact with the inner side wall of the acceleration wheel body 1, the side wall of the upper part 91 has a connecting hole, and the joint pipe 10 is connected to the connecting hole.

[0030] In the accelerator provided by the present invention, the hollow environment inside the acceleration wheel body 1, the hollow environment inside the upper part 91 of the connecting block 9, and the joint pipe 10 together constitute a negative pressure channel, and the airflow direction of the negative pressure channel is: from the vacuum hole 4 on the side wall of the acceleration wheel body 1 to the interior of the acceleration wheel and the interior of the upper part 91 of the connecting block 9, and then flows out from the joint pipe 10, wherein the joint pipe 10 is connected to a vacuum manufacturing device, and a negative pressure airflow is generated by the vacuum manufacturing device to generate a negative pressure at the vacuum hole 4 of the acceleration wheel body 1, which can adsorb the filter rod. When the motor 7 drives the rotating shaft 8 to rotate, the rotating shaft 8 drives the acceleration wheel body 1 to rotate. During the rotation of the acceleration wheel body 1, the vacuum manufacturing device connected to the joint pipe 10 generates a negative pressure at the vacuum hole 4, adsorbs the cut filter rod and accelerates its delivery to the receiving drum.

[0031] The accelerator provided by the present invention also includes a bearing and an oil seal 6, wherein the bearing is installed in the through hole of the lower portion 92, the rotating shaft 8 is passed through the bearing, and the oil seal 6 is installed at the through hole, and the oil seal 6 is used to seal the through hole. The bearing can make the rotating shaft 8 rotate more smoothly on the connecting block 9, and the sealing of the through hole by the oil seal 6 can ensure the sealing of the negative pressure channel and the adsorption effect of the vacuum hole 4 on the acceleration wheel body 1.

[0032] In addition, the accelerator provided by the present invention also includes a shell 11, the connecting block 9 is located in the shell 11, and a corresponding connecting hole is provided on the shell 11 at the connecting hole of the connecting block 9. The joint pipe 10 is inserted into the connecting hole and the connecting hole. The outer protection of the shell 11 can prevent the accelerator from being displaced by the acceleration wheel body 1, the rotating shaft 8, and the connecting block 9 during daily collisions, thereby affecting the sealing of the accelerator.

[0033] Furthermore, in order to ensure the maintenance function of the accelerator provided by the present invention, the accelerator provided by the present invention also includes a screw 12, and a screw hole is opened along the axial direction of one end of the rotating shaft 8 facing the acceleration wheel body 1, and the screw 12 passes through the end surface of the acceleration wheel body 1 and is connected to the screw hole. When the acceleration wheel body 1 needs to be disassembled, the acceleration wheel body 1 can be disassembled by loosening the screw 12 to disconnect the screw 12 and the rotating shaft 8. At the same time, the connecting hole is a threaded hole, and the joint pipe 10 is threadedly connected to the connecting hole. The threaded connection between the joint pipe 10 and the connecting hole can also ensure that the joint pipe 10 can be detachably installed, and can be disassembled during subsequent repairs or maintenance.
