Technical Field

[0001] This utility model relates to the field of tobacco machinery technology, specifically to a self-adjusting cleaning device for a cork paper cutting drum. Background Technology

[0002] In the cigarette manufacturing industry, mainstream cigarette making machines such as the ZJ17 model generally use a tipping paper cutting drum to complete the cigarette filter attachment process. Its working principle is as follows: after the tipping paper substrate is quantitatively glued by a glue roller, it is precisely cut by a high-speed rotating cutting drum to form tipping paper sheets of predetermined specifications, which are then laminated with the cigarette pack. However, in actual production, it has been found that when the glue application exceeds the critical threshold or the ambient temperature is too high or the cutting drum is unclean, abnormal adsorption can easily occur between the tipping paper sheets and the drum surface. This ultimately leads to quality problems such as air leakage and wrinkled cigarette filters, and may even cause blockage of the filter press, resulting in equipment downtime.

[0003] In view of this, in order to overcome the above problems, it is necessary to provide a self-adjusting cleaning device for the tipping paper cutting drum to remove the tipping paper adhering to the tipping paper cutting drum, so as to improve the production efficiency of the winding and splicing unit.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-7 This utility model provides a technical solution: a self-adjusting cleaning device for a cork paper cutting drum, including a base 1, a positioning block 2, a storage box 4, a baffle 6, a cleaning felt 7, and a cutting component 8. The storage box 4 is installed on the base 1 by an installation component. The positioning block 2 is movably disposed on the base 1. A support component is provided between the positioning block 2 and the baffle 6. The baffle 6 is slidably installed in the storage box 4. One end of the cleaning felt 7 is disposed in the storage box 4 and contacts the baffle 6. The cutting component 8 is provided at one end of the base 1, and a positioning mechanism is provided at the upper end of the base 1.

[0018] When the self-adjusting cleaning device of the cork paper cutting drum 14 is working, the relative position of the overall device and the cutting drum 14 is first adjusted by the positioning mechanism. The positioning block 2 can move on the base 1. The position is determined by fixing the second mounting screw in the irregular hole 16 and the fifth positioning hole 17. When the cutting drum 14 rotates at high speed, since the paper-scraping surface 80 of the scraping part 8 forms an angle of 15° to 20° with the outer circle surface of the cutting drum 14, it can initially scrape up the cork paper adhering to the cutting drum 14. At the same time, when the support screw 3 moves towards the direction of the positioning block 2, the baffle 6 moves towards the direction of the spring 5. When the positioning block 2 moves in the direction of the support screw 3, the support screw 3 will push against the baffle 6 and drive the cleaning felt 7 to move towards the cutting drum 14. Thus, the baffle 6 is set so that the cleaning felt 7 always maintains full contact with the cutting drum 14 as needed. As the cork paper cutting drum rotates, the paper scraping surface 80 of the base 1 continuously cleans large foreign objects on the cork paper cutting drum, and the cleaning felt 7 further cleans the interface. When the cleaning effect of the cleaning felt 7 is not good, cleaning fluid or lubricating fluid can be injected through the oil tank 12 on the storage box 4 to improve the cleaning effect.

[0019] The mounting components include a first positioning hole 9, a second positioning hole 10, and a first mounting screw 11. Two symmetrically distributed first positioning holes 9 are provided on the two side walls of the storage box 4, and two symmetrically distributed second positioning holes 10 are provided on the base 1 at positions corresponding to the first positioning holes 9. The lower end of the first mounting screw 11 passes through the first positioning hole 9 and is threadedly connected to the second positioning hole 10. An oil injection groove 12 is provided on the upper wall of the storage box 4. By setting the mounting components, it is convenient to install and disassemble the storage box 4 and the base 1. The oil injection groove 12 can inject lubricating liquid into the storage box 4, which can wet the cleaning felt 7 and thus fully perform flexible cleaning on the surface of the cutting drum 14, removing residual adhesive and small debris.

[0020] The support includes a support screw 3, a third positioning hole 13, and a spring 5. Two symmetrically distributed third positioning holes 13 are provided on the wall of the storage box 4 away from the cleaning felt 7. The two third positioning holes 13 are movably set with one end of the support screw 3. The storage box 4 is provided with a spring 5. One end of the spring 5 is fixedly connected to the baffle 6. When working, one end of the support screw 3 is installed in the positioning block 2, and the other end passes through the storage box 4 and extends into the interior of the storage box 4. The spring 5 is sleeved on the support screw 3. By adjusting the length of the support screw 3 in the storage box 4, the position of the baffle 6 can be controlled, thereby adjusting the position of the cleaning felt 7.

[0021] One end of the support screw 3 inside the storage box 4 contacts the baffle 6. A spring 5 is sleeved on the outer wall of the support screw 3. One end of the spring 5 is fixedly connected to the inner wall of the storage box 4, and the other end is fixedly connected to the baffle 6. The arrangement of the support screw 3, the baffle 6 and the spring 5 can adjust the position of the cleaning felt 7 when the position of the baffle 6 is adjusted, so that the baffle 6 can apply continuous pressure to the cleaning felt 7 and ensure full contact between the cleaning felt 7 and the cutting drum 14.

[0022] The scraper 8 is integrally formed with the base 1. One end of the scraper 8 is provided with a cutting drum 14. The front of the scraper 8 is provided with a scraping paper cutting surface 80. The included angle between the scraping paper cutting surface 80 and the outer circular surface of the cutting drum 14 is 15° to 20°. The edge of the scraping paper cutting surface 80 is provided with a rounded corner 81. The radius of the rounded corner 81 is 0.3mm. The specific included angle and rounded corner 81 can effectively scrape off the cork paper adhering to the cutting drum 14, and avoid damage to the cutting drum 14.

[0023] The positioning mechanism includes a fourth positioning hole 15, a shaped hole 16, a fifth positioning hole 17, a frame 18, and a second mounting screw. The shaped hole 16 is aligned with the fifth positioning hole 17 and is initially fixed by the second mounting screw. The lateral position of the base 1 is finely adjusted so that a gap of 0.5-1mm is left between the paper scraping surface 80 and the outer surface of the cutting drum 14. The fourth positioning hole 15 is provided on the wall of the positioning block 2. One end of the frame 18 passes through the fourth positioning hole 15 and is fixedly connected to it. Two symmetrically distributed fifth positioning holes 17 are provided on the lower wall of the positioning block 2. The upper part has irregular holes 16 corresponding to the positions of the two fifth positioning holes 17. The upper end of the second mounting screw passes through the fifth positioning hole 17 and is threaded to the fourth positioning hole 15. In use, the second mounting screw is rotated in the forward direction to loosen the second mounting screw from the base 1. The second mounting screw is no longer fixing the position of the positioning block 2. At this time, the positioning block 2 can be moved left and right, which drives the support screw 3 to move, thereby adjusting the position of the cleaning felt 7. After the adjustment is completed, the second mounting screw is turned in the reverse direction to tighten the second mounting screw at the lower end of the base 1, thereby fixing the position of the positioning block 2.

[0024] The irregular hole 16 is an elongated oval slot with a length of 10mm. The end of the support screw 3 away from the storage box 4 is fixed in the positioning block 2. The opening direction of the irregular hole 16 is consistent with the moving direction of the positioning block 2. The elongated oval slot provides space for the movement of the positioning block 2, making it easy to adjust the position.

[0025] The cleaning felt 7 is located outside the storage box 4, and one end of it contacts the cutting drum 14. The cleaning felt 7 has a trapezoidal cubic structure and is made of wool felt material with a density of 50D. The high-density sponge material can fully absorb the lubricating liquid poured into the oil tank 12 on the storage box 4, ensuring the cleaning effect of the cleaning felt 7. The trapezoidal structure makes it easier to contact the cutting drum 14.

[0026] The base 1, positioning block 2, support screw 3, storage box 4, spring 5, and baffle 6 are all made of 45# steel, and the Rockwell hardness of the base 1, positioning block 2, support screw 3, storage box 4, spring 5, and baffle 6 is HRC50. 45# steel has good mechanical properties, and after treatment, it reaches the Rockwell hardness of HRC50, which ensures the strength and wear resistance of each component and extends the service life of the device.

[0027] Finally, it should be noted that: all parts not described in this utility model are the same as or can be implemented using existing technology. The above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
