Description

Technical Field

[0001] The present application relates to the technical field of cigarette production equipment, and in particular to a timed automatic cleaning device for a ZJ17 cigarette making machine rubbing drum. Background Art

[0002] Currently, the structure of filter cigarettes on the market can be divided into two parts: the cigarette and the filter. The two parts are wrapped and bonded by kraft paper, and this wrapping and bonding process is achieved by the twisting and forming system.

[0003] The function of the splicing and forming system is to receive and merge the double-length filter segment and the two separated single-length cigarettes to form a cigarette group of "single-length cigarette + double-length filter segment + single-length cigarette"; then the three segments of the "cigarette group" are brought closer to each other and the gaps are eliminated, and aligned with the center line of the machine; the front end of the tipping paper is pasted on the "cigarette group", and the tipping paper is wrapped around the "cigarette group" by the interaction of the splicing drum and the rubbing board to form a double-length filter cigarette, which is cut into two filter cigarettes on the filter cigarette cutting drum.

[0004] At present, the ZJ17 cigarette making machine mainly realizes the forming of cigarettes by twisting and splicing the drum wheel. When the twisting and splicing drum wheel receives the "cigarette group" with the tipping paper from the drum wheel, the suction in the cigarette receiving groove of the twisting and splicing drum wheel makes the "cigarette group" fall into the cigarette receiving groove. At the same time, the suction from the air holes on the working surface of the twisting and splicing drum wheel spreads the tipping paper on the working surface with straight lines. Before entering the twisting and splicing working position, the starting rail takes the "cigarette group" out of the cigarette receiving groove, so that the "cigarette group" rolls purely between the working surface of the twisting and splicing drum wheel and the washboard, so that the tipping paper tightly wraps and adheres the "cigarette group" to form a double-length filter cigarette. After forming, the double-length filter cigarette rolls out from the washboard and just falls into the cigarette receiving groove of the twisting and splicing drum wheel. If the filter cigarette is displaced due to sliding during the twisting and splicing process, the auxiliary effect of the return drum wheel can help the double-length filter cigarette fall into the cigarette receiving groove. During the pure rolling process of the "cigarette group", the heated washboard dries the glue on the tipping paper in time.

[0005] During the production process, since one side of the kraft paper is coated with glue, a small amount of glue overflow is inevitable when splicing. After a long period of accumulation, glue scale will form, which will not only block the air intake holes, but also cause concave indentations in the splicing of the "group cigarettes", affecting the appearance quality of the cigarettes.

[0006] The splicing drum is mainly cleaned by a cleaning brush. Existing cleaning devices generally adopt a continuous cleaning mode. The cleaning brush needs to continuously press the working surface of the splicing drum, which causes serious wear on the cleaning brush and the working surface of the splicing drum. The wear of the brush not only fails to achieve the cleaning effect, but also requires frequent replacement of the brush, which increases production costs. The wear of the splicing drum will directly affect the splicing quality of filter cigarettes. In addition, as the use time of the cleaning brush increases, a large amount of debris is easily attached to the cleaning brush, resulting in a deterioration in the cleaning effect of the brush.

[0034] See also Figure 1-7The timing automatic cleaning device for the splicing drum of the ZJ17 cigarette making machine comprises a bottom plate 1, a cleaning assembly 2, a driving assembly 3, a lifting assembly 4, and a self-cleaning block 5. The bottom plate 1 is fixedly connected to the ZJ17 cigarette making machine through a kidney hole 11, and the installation position of the bottom plate 1 can be fine-tuned through the kidney hole 11. The lifting assembly 4 is installed at the first installation hole 13 of the bottom plate 1, and the lifting assembly 4 is installed with a cleaning assembly 2 for cleaning the splicing drum, and a square opening 12 is opened on the bottom plate 1, so that the lifting assembly 4 can drive the cleaning assembly 2 to move up and down to clean the gap of the splicing drum. The bottom plate 1 is also equipped with a driving assembly 3 for providing power to the cleaning assembly 2, and a self-cleaning block 5 for cleaning the cleaning assembly.

[0035] like Figure 6 As shown, the lifting assembly 4 includes a lifting seat 41, a cylinder 43, a fixed rod 44, an air pipe 45, and a roller 48. The cylinder body of the cylinder 43 is fixedly connected to the fixed rod 44, the fixed rod 44 is fixedly connected to the first mounting hole 13, and the cylinder 43 is installed vertically. The cylinder 43 is connected to the external air supply device through the air pipe 45. The telescopic part of the cylinder 43 is fixedly connected to the second boss 42 on the lifting seat 41. Two slide rails 15 are arranged on the side of the bottom plate 1. Roller rods 46 are fixedly installed at the four corners of the lifting seat 41. Rollers 48 are rotatably installed on the roller rods 46 through the third bearing 47. The lifting seat 41 is slidably installed between the two slide rails 15 through the roller 48, thereby improving the stability of the lifting seat 41 when sliding up and down. A cleaning assembly 2 for cleaning the rubbing drum is installed on one side of the lifting seat 41, and a driving assembly 3 for providing power to the cleaning assembly 2 is installed on the other side of the lifting seat 41. During use, the extension and retraction of the cylinder 43 can drive the lifting seat 41 to slide up and down, thereby changing the position of the cleaning component 2. When the splicing drum needs to be cleaned, the cylinder 43 extends to drive the cleaning component 2 to move down and contact the splicing drum; after cleaning, the cylinder 43 shortens to drive the cleaning component 2 to rise and reset, and the splicing drum can produce normally.

[0036] like Figure 3-5As shown, the cleaning assembly 2 includes a connecting seat 25, a rotating shaft 21, a brush 22, a spring 23, and a second bearing 29. The connecting seat 25 is fixedly connected to the lifting seat 41 by screws, and the rotating shaft 21 is rotatably mounted on the connecting seat 25 through the first bearing 28. The brush 22 is sleeved on the rotating shaft 21, and a protrusion 211 is provided on the rotating shaft 21. The brush 22 is provided with a sliding groove 221 corresponding to the protrusion 211, so that the brush 22 can slide along the axial direction of the rotating shaft 21. A first boss 26 is provided on the connecting seat 25, and a second bearing 29 is rotatably installed on the bottom of the first boss 26 through a semicircular head screw. The second bearing 29 contacts one end of the brush 22, and the end surface of the brush 22 contacting the second bearing 29 is a beveled surface; further, a spring 23 is installed on the rotating shaft 21 through a fixing screw 24, and the spring 23 contacts the other end of the brush 22, so that the brush 22 is pressed against the second bearing 29 under the action of the spring 23. When the brush 22 rotates, since the contact surface between the brush 22 and the second bearing 29 is a beveled surface, the brush 22 can reciprocate along the axial direction of the rotating shaft 21, thereby improving the cleaning effect of the brush 22 on the rubbing drum.

[0037] like Figure 6 As shown, the driving assembly 3 includes a motor 31, a first gear 32, and a second gear 33. The motor 31 is fixedly mounted on the side of the lifting seat 41, and the first gear 32 is fixedly connected to the output shaft thereof, and the second gear 33 meshing with the first gear 32 is fixedly connected to the rotating shaft 21. When the motor 31 is started, the first gear 32 and the second gear 33 are driven to rotate the rotating shaft 21, thereby driving the brush 22 to rotate.

[0038] like Figure 7 As shown, the trachea quick-connect connector 52 is divided into a male head and a female head, wherein the male head is connected to the external air supply device through a pipeline, and the male head is fixedly connected to the second mounting hole 14 on the bottom plate 1, and the female head is installed at the air inlet of the self-cleaning block 5. The spraying angle of the self-cleaning block 5 can be fine-tuned through the trachea quick-connect connector 52, thereby ensuring the spraying effect of the self-cleaning block 5 on the brush 22. A row of spray holes 51 corresponding to the brush 22 are evenly opened at the bottom of the self-cleaning block 5, so that the sprayed airflow is more uniform, thereby improving the cleaning effect on the brush 22.

[0039] Furthermore, in order to improve the degree of automation of the device, the motor 31 and the external air supply device are electrically connected to the PLC and controlled by the PLC.

[0040] The working process of this device:

[0041] When it is necessary to clean the splicing drum, the external air supply device is controlled by PLC to provide an air source for the cylinder 43, so that the cylinder 43 extends, driving the lifting seat 41 to descend, thereby driving the brush 22 to descend and contact the working surface of the splicing drum, and the motor 31 is started by PLC control to drive the rotating shaft 21 to rotate, so that the brush 22 reciprocates along the axial direction of the rotating shaft 21 while rotating, and cleans the working surface of the splicing drum. At the same time, the external air supply device is controlled by PLC to provide an air source for the self-cleaning block 5, so that the attachments on the brush 22 are sprayed to ensure the cleaning effect of the brush 22; after cleaning is completed, the external air supply device is controlled by PLC to stop supplying air, so that the cylinder 43 rises and resets, and the self-cleaning block 5 stops blowing. At the same time, the motor 31 is controlled to stop running and wait for the next cleaning.
