Technical Field

[0001] The utility model relates to the technical field of tobacco rolling and splicing equipment, in particular to a drum cleaning device for a cigarette rolling and splicing machine. Background Art

[0002] In the tobacco industry, the current mainstream cigarette rolling and connecting equipment includes models such as ZJ17, ZJ118, and ZJ116. Among them, the ZJ17 cigarette packaging equipment is mainly composed of the YJ17 feeding and strip-forming machine, the YJ17 rolling and forming machine, and the YJ27 filter tip connecting machine. The main function of the YJ27 filter tip connecting machine is to complete the filter tip connecting work.

[0003] After the cigarettes are rolled and formed by the rolling and forming machine, the double-length tobacco rods are transferred by a robot to the filter tipping machine. They are then joined with the double-length filter at the joining drum, joined with the tipping paper at the closing drum, and then spliced ​​by the splicing drum. The laser perforation drum then completes the online perforation. After the spliced ​​double-length cigarettes are transferred from the splicing drum to the laser perforation drum, they rotate one full revolution on the pneumatic wheel. Then, a laser head positioned at the twelve o'clock position on the laser perforation drum burns the cigarettes, creating uniform round holes.

[0004] Laser burning of the tipping paper and filter creates residual dust that adheres to the surface of the laser perforated drum, gradually clogging the drum's air intake holes and affecting the laser perforation of cigarettes. The laser perforated drum needs to be removed and cleaned at the end of each night shift, and the production process requires multiple stops for cleaning. This cleaning requires manual shutdown and the use of a copper brush. Due to the crowded location of the laser perforated drum, cleaning is difficult and time-consuming, seriously impacting production efficiency. Failure to clean the drum promptly or properly can also lead to product quality issues. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, exemplary embodiments of the present invention are described below in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding. These details should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0030] In the description of this utility model, it should be noted that the term "including" and its variations represent open inclusion, that is, "including but not limited to." The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0031] The utility model provides a cigarette making machine drum cleaning device, Figure 1 and Figure 2 As shown, it includes a brush support 100 and a cleaning brush 200; the brush support 100 includes a fixing frame 1 and a brush shaft 2; the fixing frame 1 includes a mounting plate 11 and a support plate 12, the mounting plate 11 is provided with a first through hole 111, which is used to be connected to the threaded hole of the baffle support of the rubbing drum smoke wheel by bolts. The support plate 12 is set at one end of the mounting plate 11, and the support plate 12 can be fixed to the mounting plate 11 by welding, riveting, integral setting, etc., making the entire fixing frame 1 more stable. The support plate 12 is provided with a second through hole 121; the first end of the brush shaft 2 passes through the second through hole 121 and is fixed to the support plate 12; the cleaning brush 200 is rotatably sleeved on the brush shaft 2.

[0032] The bottom of the laser drilling drum 300 has space for accommodating the cleaning brush 200. The shape of the support plate 12 avoids the drum inside the equipment and other fixed supports provided by the equipment, and adapts to the space at the bottom of the laser drilling drum 300. Two first through holes 111 can be provided, which are connected to the threaded holes of the baffle support of the splicing drum and the smoke plucking wheel by two bolts, which is easy to install and does not require modification to the existing equipment. Figure 3 As shown, when the cleaning brush 200 is mounted on the baffle support of the splicing drum smoke wheel through the brush support 100, the cleaning brush 200 is in contact with the bottom surface of the laser drilling drum 300. When the laser drilling drum 300 rotates, it can drive the cleaning brush 200 to rotate around the brush shaft 2, and automatically clean the surface of the laser drilling drum 300 online. At the same time, the cleaned glue scale and dust can directly fall into the waste smoke collection box on the lower side of the laser drilling drum 300, which is convenient for cleaning. It can also prevent glue scale and dust from falling into other parts of the equipment and affecting equipment safety and product quality. The cleaning brush 200 continuously cleans the surface of the laser drilling drum 300 online, and less dust accumulates on the surface of the laser drilling drum 300. The cleaning brush 200 can be made of a plastic brush, which is low in cost and will not cause damage to the surface of the laser drilling drum 300.

[0033] The threaded hole of the splicing drum's smoke plucking wheel baffle support extends perpendicularly to the axis of the laser-drilling drum 300. Accordingly, the first through-hole 111 extends perpendicularly to the second through-hole 121. This allows the cleaning brush 200 to extend in the same direction as the axis of the laser-drilling drum 300 when the mounting bracket 1 is secured to the splicing drum's smoke plucking wheel baffle support. This makes it easier for the laser-drilling drum 300 to rotate the cleaning brush 200, reduces the length of the cleaning brush 200, and achieves a good cleaning effect. Preferably, the second through-hole 121 is configured as an elongated hole, allowing the brush shaft 2 to move along the second through-hole 121. This allows the cleaning brush 200 to be adjusted relative to the laser-drilling drum 300 in a radial direction, achieving different cleaning effects. When there is a lot of dirt and dust on the surface of the laser drilling drum 300, the distance between the cleaning brush 200 and the laser drilling drum 300 is reduced to increase the cleaning force; when there is less dirt and dust on the surface of the laser drilling drum 300, the distance between the cleaning brush 200 and the laser drilling drum 300 is increased to reduce the cleaning force.

[0034] There is a gap between the inner wall of the cleaning brush 200 and the brush shaft 2, so that the cleaning brush 200 can rotate around the brush shaft 2, but the cleaning brush 200 can also move along the brush shaft 2. In order to prevent the cleaning brush 200 from moving too much along the extension direction of the brush shaft 2, the first end of the brush shaft 2 is provided with a baffle 21, and the second end thereof is provided with a blocking component. The cleaning brush 200 is restricted between the baffle 21 and the blocking component. In this way, the cleaning brush 200 can be prevented from falling off from the second end of the brush shaft 2 during use.

[0035] In one embodiment, Figure 1 As shown, the first end of the brush shaft 2 is provided with a first threaded rod 22, and the outer end of the first threaded rod 22 is provided with a first nut 23 adapted to the first threaded rod 22, and the first nut 23 abuts against the outer side of the support plate 12; the baffle 21 is provided at the inner end of the first threaded rod 22, abutting against the inner side of the support plate 12. When installing the brush shaft 2, after the first threaded rod 22 is passed through the second through hole 121, the baffle 21 is abutted against the inner side of the support plate 12, and the first nut 23 is then tightened from the outer end of the first threaded rod 22, so that the first threaded rod 22 is fixed to the support plate 12 through the first nut 23 and the baffle 21, and the brush shaft 2 can be stably and reliably fixed to the support plate 12. It can be understood that the end away from the cleaning brush 200 is the outer end, and the end close to the cleaning brush 200 is the inner end.

[0036] In one embodiment, the baffle 21 is fixedly arranged at the inner end of the first threaded rod 22, and the brush shaft 2 between the baffle 21 and the blocking component is a smooth rod, which can reduce the friction between the inner wall of the cleaning brush 200 and the brush shaft 2, so that the cleaning brush 200 rotates smoothly around the brush shaft 2.

[0037] In one embodiment, the baffle 21 is configured as a second nut that is compatible with the first threaded rod 22. The second nut is screwed onto the first threaded rod 22 and can move along the first threaded rod 22, so that the distance between the baffle 21 and the blocking component can be adjusted to adapt to cleaning brushes 200 of different lengths.

[0038] In one embodiment, a second threaded rod is provided at the second end of the brush shaft 2, and the blocking member is configured as a third nut adapted to the second threaded rod. When the cleaning brush 200 moves toward the second end of the brush shaft 2, it abuts against the third nut, thereby preventing the cleaning brush 200 from falling off the second end of the brush shaft 2.

[0039] In one embodiment, reference Figure 1 and Figure 2 As shown, the second end of the brush shaft 2 is provided with a slot 24, and the blocking member is configured as a retaining spring 25, which is disposed within the slot 24. When the cleaning brush 200 moves toward the second end of the brush shaft 2, it abuts against the retaining spring 25, thereby preventing the cleaning brush 200 from falling off the second end of the brush shaft 2. When replacing the cleaning brush 200, the retaining spring 25 can be quickly removed from the slot 24, allowing the cleaning brush 200 to be removed quickly and easily for cleaning or replacement, making the operation convenient and quick.

[0040] The cleaning device has a simple structure, is easy to install, and is highly practical. The cleaning brush rotates along with the rotation of the laser punching drum to clean the surface of the drum, realizing online automatic cleaning without the need to stop the machine for manual cleaning, and meeting the equipment operation requirements. It solves the current problem in the tobacco industry that the laser punching drum of the ZJ17 model needs to be stopped during production and manually disassembled for cleaning at regular intervals, affecting the equipment operation efficiency and product quality.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
