Description

Technical Field

[0001] The invention relates to the technical field of cleaning a cigarette group joining drum wheel, and in particular to a friction rotating automatic cleaning device for a filter tip joining machine drum wheel. Background Art

[0002] At present, the function of the splicing drum of the splicing machine is to splice the tipping paper on the surface of the plain cigarette and the filter to form a double-length cigarette. During the process of rolling and splicing cigarettes, if there is too much glue at the overlap of the double-length cigarette group, the glue at the overlap is not easy to dry, and the glue applied on the adhesive surface of the tipping paper is easy to overflow from the overlap or connection, resulting in adhesion to the splicing drum surface to form glue scale. As the production process proceeds, the glue scale adhered to the splicing drum surface gradually accumulates, and foreign objects such as cigarette dust, paper scraps and paper pieces will also adhere to the splicing drum surface under the adhesion of the glue scale.

[0003] Glue scale and foreign matter will affect the quality of cigarette splicing, resulting in quality defects such as wrinkles, tipping paper deviation and cigarette leakage. At the same time, glue scale and foreign matter will also affect the stability of the splicing process, resulting in an increased failure rate of the splicing drum. In order to ensure the quality of cigarette splicing and the stability of the equipment, the operator needs to check the cleanliness of the splicing drum surface every hour and clean it when necessary. This method affects the production efficiency of the equipment and increases the workload of the operator.

[0004] Although there are devices for cleaning the splicing drum in the prior art, the existing cleaning devices generally realize transmission by driving gears with toothed belts. In actual use, such toothed belts are prone to breakage, resulting in a short service life and the need for regular replacement, which greatly increases the subsequent maintenance workload and reduces production efficiency. In addition, the cleaning device usually uses blowing to assist in cleaning the surface of the splicing drum, but this method has very limited ability to clean glue scale and foreign matter and cannot effectively achieve overall cleaning of the splicing drum. Summary of the invention

[0005] In view of the problems existing in the prior art, the present invention provides a friction rotating automatic cleaning device for the drum wheel of a filter tip assembler, which solves the problem that the existing device for cleaning the splicing drum wheel is prone to breakage during transmission through a toothed belt, thereby extending the service life of the device and reducing the subsequent maintenance cost. At the same time, the cleaning brush cylinder can move axially back and forth along the rotating shaft relative to the splicing drum wheel, thereby improving the cleaning effect of the splicing drum wheel and enhancing production efficiency.

[0030] In this embodiment, a mounting base 3 is installed on the equipment on one side of the rubbing drum 1, and a transmission box 4 is connected to the mounting base 3. The inner wall of the transmission box 4 is rotatably connected with a fixed shaft 5 and a transmission shaft 6. One end of the transmission shaft 6 extends to the outside of the transmission box 4, and a rotating shaft 7 is fixedly mounted on the extended end. A baffle 8 is connected to the other end of the rotating shaft 7, and a cleaning brush cylinder 9 is slidably mounted on the outer side of the rotating shaft 7.

[0031] The cleaning brush cylinder 9 is rollingly connected with the surface of the rubbing drum 1 and the inner wall of the smoke groove 2, and can be driven to rotate on the surface of the rotating shaft 7 through friction when the rubbing drum 1 rotates.

[0032] Furthermore, the fixed shaft 5 is axially provided with a fixed shaft internal gear 14 and a fixed shaft external gear 15, and the transmission shaft 6 is axially provided with a transmission shaft internal gear 17 and a transmission shaft external gear 16, respectively. The fixed shaft internal gear 14 is meshingly connected with the transmission shaft internal gear 17, and the fixed shaft external gear 15 is meshingly connected with the transmission shaft external gear 16.

[0033] In this embodiment, if Figure 3As shown, the outer side surface of the fixed shaft 5 is respectively fixedly sleeved with a fixed shaft inner gear 14 and a fixed shaft outer gear 15, the outer side surface of the transmission shaft 6 is respectively fixedly sleeved with a transmission shaft inner gear 17 and a rotating sleeve with a transmission shaft outer gear 16, the fixed shaft inner gear 14 is meshingly connected with the transmission shaft inner gear 17, the fixed shaft outer gear 15 is meshingly connected with the transmission shaft outer gear 16, one side of the transmission shaft outer gear 16 is fixedly connected with a cam 18, and both sides of the inner radial direction of the transmission shaft inner gear 17 are slidably sleeved with a push rod 20, and the two ends of the push rod 20 respectively cooperate with the cam 18 and the ring 11 to slide against each other.

Due to the existence of the inclined surface, the distance between the multiple push rods 20 and the cam 18 along the axial direction of the rotating shaft is constantly changing, and the multiple push rods 20 can continuously reciprocate along the axial direction of the rotating shaft.

[0038] Further, such as Figure 5 As shown, an opening 13 is provided at one end of the cleaning brush cylinder 9 close to the transmission box 4 , and a ring 11 is slidably mounted on the rotating shaft 7 between the cleaning brush cylinder 9 and the transmission box 4 , and a boss 12 is provided on the ring 11 , and the boss 12 is matched and connected with the opening 13 .

The cam 18 is fixedly connected to the side of the transmission shaft outer gear 16 close to the limiting ring 23, and is rotatably mounted on the outer side of the small diameter section 22. A curved platform 19 is provided on the cross section of the side of the cam 18 close to the limiting ring 23. The push rod 20 passes through the sliding sleeve in the large diameter section 21, and the end close to the curved platform 19 is circular and slidably connected with the curved platform 19, while the other end close to the circular ring 11 is flat and slidably connected with the circular ring 11.

[0042] The cleaning brush cylinder 9 meshing and rollingly connected with the splicing drum 1 rotates by friction, thereby driving the rotating shaft 7 to rotate, so as to drive the transmission shaft internal gear 17 to mesh and rotate with the fixed shaft internal gear 14, and at the same time drive the fixed shaft 5 to rotate with the fixed shaft external gear 15, thereby driving the transmission shaft external gear 16 meshing with the fixed shaft external gear 15 to rotate, thereby driving the cam 18 to rotate, and through the rotation of the cam 18, the push rod 20 is pushed back and forth along the axial direction of the rotating shaft 7, thereby driving the cleaning brush cylinder 9 to reciprocate along the axial direction while rotating on the rotating shaft surface. Not only can the surface of the splicing drum 1 be rotated and cleaned by the rotation of the cleaning brush cylinder 9, but it can also reciprocate along the axial direction of the rotating shaft 7 to achieve cleaning along the axial direction of the splicing drum 1, thereby increasing the cleaning effect on the surface of the splicing drum 1 and the inside of the smoke receiving groove 2, and the durability is greatly increased through the meshing connection of the gears.

[0043] Furthermore, a baffle 8 is provided at one end of the rotating shaft 7 away from the transmission box 4 , and a cleaning brush cylinder 9 is sleeved on the rotating shaft 7 between the baffle 8 and the transmission box 4 .

Such an arrangement of the spring 10 can provide a rebound force when the cleaning brush cylinder 9 is reset, thereby ensuring the stability and smoothness of the cleaning brush cylinder 9 when it reciprocates axially along the rotating shaft 7.

[0046] The invention provides a friction rotating automatic cleaning device for a filter tip connecting machine drum wheel, wherein the cleaning brush cylinder meshing and rollingly connected with the rubbing drum wheel drives itself to rotate by friction when the rubbing drum wheel rotates, thereby driving the rotating shaft to rotate, thereby driving the inner gear of the transmission shaft to mesh and rotate with the inner gear of the fixed shaft, and at the same time driving the outer gear of the fixed shaft to rotate, thereby driving the outer gear of the transmission shaft meshing with the outer gear of the fixed shaft to rotate, further driving the cam to rotate, and through the rotation of the cam, the push rod is pushed back and forth along the axial direction of the rotating shaft, thereby driving the cleaning brush cylinder to reciprocate along the axial direction while rotating the surface of the rotating shaft, which can not only rotate and clean the surface of the rubbing drum wheel through the rotation of the cleaning brush cylinder, but also reciprocate along the axial direction of the rotating shaft to achieve cleaning along the axial direction of the rubbing drum wheel, thereby increasing the cleaning effect on the surface of the rubbing drum wheel and the inside of the cigarette receiving groove, and greatly increasing the durability through the meshing connection of the gears;

[0047] In addition, the device uses gear meshing transmission instead of the traditional transmission method of driving the gears with a toothed belt, which greatly increases the durability of the device during specific use, reduces maintenance costs, and improves production efficiency.
