Description
TECHNICAL FIELD
[0001] The utility model belongs to cigarette machine blowing removes tail end technical field, concretely relates to a cigarette machine blowing removes tail end system. BACKGROUND
[0002] The cigarette supply system of YJ27 tipping machine mainly consists of a tipping drum, a cigarette cutting drum (first cutting drum), a cigarette cutter assembly, a separating drum and a merging drum. The process flow is that the tipping drum receives double-length cigarettes from a cigarette maker, the first cutting drum cuts the double-length cigarettes into two equal-length cigarettes, the separating drum separates the two equal-length cigarettes, and the merging drum forms a cigarette group by inserting a double-length filter segment between the two equal-length cigarettes.
[0003] The twisting and tipping forming system of YJ27 tipping machine mainly consists of a closing drum, a twisting plate, a conveying drum, a twisting and tipping drum and a filter cigarette cutting drum. The process flow is that the closing drum completes the alignment and pasting of tipping paper, the twisting and tipping drum completes the twisting and tipping process, the conveying drum completes the conveying of double-filter cigarettes, and the filter cigarette cutting drum completes the final cutting and rejection of filter cigarettes.
[0004] The cigarette with trapped tobacco ends is a common quality defect of cigarette makers. When the YJ27 tipping machine is running, the tobacco ends that fall from the cigarettes in the cigarette group will be scattered irregularly due to air flow and inertia during the running process. The tobacco ends may be scattered on the tipping paper that has not been wrapped on the closing drum during the twisting and forming process, or may be scattered on the twisting and tipping drum. The tobacco ends will be wrapped together with the tipping paper and the cigarettes during the subsequent twisting and tipping process, and the cigarette with trapped tobacco ends is formed.
[0005] To reduce the generation of the cigarette with trapped tobacco ends, a tobacco end removing device composed of a suction hood and a blowing block is installed on the original YJ27 tipping machine to absorb and blow off the tobacco ends. The suction hood is installed above the separating drum to absorb the scattered paper scraps and tobacco ends during the conveying of the cut cigarettes. The blowing block is installed below the tipping paper cutter guard of the YJ27 tipping machine to blow off the scattered tobacco ends from the cigarettes conveyed by the closing drum.
[0006] However, the suction hood above the separating drum cannot handle the tobacco ends generated by the merging drum and the subsequent twisting and tipping drum. The blowing block below the tipping paper cutter guard only provides an outward axial air flow, which cannot separate the air flow into two directions. Therefore, the tobacco end removing device installed on the original YJ27 tipping machine has a certain effect on removing the tobacco ends, but cannot effectively remove all the tobacco ends, and further improvement is still needed.

[0028] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.
[0029] Example:
[0030] From the original machine's process flow, it can be seen that the main areas where particulate matter is generated are the converging drum, the approaching drum, and the rubbing drum. Based on the space constraints of these three areas in the original machine, a blower system for removing particulate matter was designed, which may include: a particulate matter blowing device 10 for the converging drum, a cleaning device 20 for the approaching drum, and a cleaning device 30 for the rubbing drum. Figure 1 As shown.
[0031] like Figure 2 and Figure 3 As shown, this utility model provides a cigarette machine blowing and dust removal system, including a converging drum blowing device 10. The converging drum blowing device 10 includes a fixed shaft 100, a swing base 101, a swing rod 102, and a converging drum blowing block 103 disposed below the converging drum 100. One end of the fixed shaft 100 is connected to a support plate 3 near the drum cleaning brush 2, which can be directly installed using existing equipment. The other end of the fixed shaft 100 is connected to one end of the swing base 101. One end of the swing rod 102 is rotatably connected to the swing base 101, thereby allowing the swing rod 102 to swing relative to the fixed shaft 100. The other end of the rod 102 is connected to the converging drum blower block 103, which is used to adjust the distance between the converging drum blower block 103 and the converging drum 1 by rotating one end of the swing rod 102. When the swing rod 102 is swung, the converging drum blower block 103 can swing along with it, thereby adjusting the up and down of the converging drum blower block 103 and thus adjusting the distance between the converging drum blower block 103 and the converging drum 1. Both sides of the other end of the swing base 101 are threaded with positioning bolts 104. The two positioning bolts 104 abut against the two sides of the swing rod 102 respectively, thereby positioning the swing rod 102.
[0032] Preferably, one end of the fixed shaft 100 connected to the support plate 3 can be a screw structure for easy installation, and the other end of the fixed shaft 100 can be a round rod structure, which can be as follows: Figure 1 and Figure 2 The shown fits and is clamped to one end of the swing base 101.
[0033] This utility model provides a converging drum blowing device, which is directly installed on the support plate 3 of the original machine near the drum cleaning brush 2, reducing the overall footprint. During operation, the airflow blown by the converging drum blowing block 103 can blow away the paper scraps and tobacco dust remaining on the converging drum 1, and carry the tobacco dust out to the waste bin. The blowing continues during the operation of the equipment, thereby reducing the accumulation of tobacco dust and reducing the quality defects of the tobacco dust. When the equipment stops, the blowing stops. This invention rotatably connects one end of the swing rod 102 to the swing base 101, allowing adjustment of the distance between the converging drum blower block 103 and the converging drum 1 located at the other end of the swing rod 102. Then, the positioning bolt 104 at the other end of the swing base 101 abuts against the swing rod 102, thereby positioning the converging drum blower block 103. This allows the position of the converging drum blower block 103 to be adjusted according to actual conditions, providing high flexibility. Furthermore, the friction between the positioning bolt 104 and the swing rod 102 can be adjusted. When blockage occurs at the converging drum blower block 103, the converging drum blower block 103 can swing downwards, minimizing disruption to the normal operation of the equipment.
[0034] As a preferred embodiment of this invention, it should be further explained that a proximity switch 105 is also installed at the other end of the swing base 101, located above the swing arm 102. When the swing arm 102 triggers the proximity switch 105, the distance between the converging drum blower block 103 and the converging drum 1 is minimized. Under normal circumstances, the converging drum blower device 10 can be controlled to operate under this condition. Once a blockage occurs, the converging drum blower block 103 will drive the swing arm 102 to swing downward, thereby causing the swing arm 102 to disengage from the proximity switch 105. After the proximity switch 105 loses its signal, a stop signal can be remotely issued to avoid equipment failure due to excessive blockage.
[0035] As a preferred embodiment of this invention, it should be further explained that the swing base 101 has an adjustment hole extending through its upper and lower parts in the middle. A rotating shaft 106 is installed in the adjustment hole. One end of the swing rod 102 is a sleeve structure rotatably connected to the rotating shaft 106. The sleeve structure can be located slightly above one end of the swing rod 102, so that the sleeve structure can extend into the adjustment hole. The lower part of the other end of the swing base 101 has a relief groove, which allows the middle part of the swing rod 102 to rotate in the relief groove. When the swing rod 102 abuts against the inner top surface of the relief groove, the swing rod 102 triggers the proximity switch 105, which can allow the swing rod 102 to rotate to a horizontal state, so that the converging drum blower block 103 at the other end of the swing rod 102 can cooperate more tightly with the converging drum 1. Two positioning bolts 104 are respectively threaded to both sides of the relief groove, making the operation simple and convenient.
[0036] As a preferred embodiment of this invention, it should be further explained that a limiting plate 107 detachably connected to the swing base 101 is provided below the adjustment hole. The side of the limiting plate 107 facing the converging drum blower block 103 is an inclined surface structure that facilitates the downward swing of the swing rod 102. When the swing rod 102 contacts the proximity switch 105, there is a gap between the swing rod 102 and the limiting plate 107. When the swing rod 102 swings downward, it contacts the inclined surface. In this way, while limiting the swing angle of the swing rod 102 by the inclined surface, the swing rod 102 can also have a greater degree of rotational freedom.
[0037] As a preferred embodiment of this invention, it should be further explained that the converging drum blower block 103 is detachably connected to the other end of the swing arm 102 via a movable connector 108. One end of the movable connector 108 is slidably connected to the top surface of the other end of the swing arm 102, and one end of the movable connector 108 is detachably connected to the other end of the swing arm 102 via a locking bolt 109. Different movable connectors 108 can be designed according to actual conditions to adapt to the installation requirements of the converging drum blower block 103. The other end of the swing arm 102 has an elongated hole extending along its length. The screw part of the locking bolt 109 passes through the elongated hole from below the swing arm 102 and is threadedly connected to the movable connector 108. The nut part of the locking bolt 109 abuts against the ground of the swing arm 102, thereby allowing the relative position of the converging drum blower block 103 to be adjusted appropriately, so that the converging drum blower block 103 can better remove smoke.
[0038] As a preferred embodiment of this invention, it should be further explained that the converging drum blower block 103 includes a mounting plate 1031, a central blower hood 1032 and two side blower hoods 1033, both mounted on the upper end of the mounting plate 1031. The two side blower hoods 1033 are respectively mounted on both sides of the central blower hood 1032. A first air inlet pipe connector 1034 communicating with the interior of the central blower hood 1032 is mounted on the lower end of the mounting plate 1031. 34. The gas source is connected through a pipe. Small air outlets are opened on both sides of the central blower hood 1032 to blow airflow to the two side blower hoods 1033. The side blower hoods 1033 are open on one side and the other side facing the central blower hood 1032. The central blower hood 1032 blows air to the side blower hoods 1033 through the small air outlets on both sides, thereby forming a stable high-speed airflow. The high-speed airflow can form an adsorption pressure, thereby carrying away the paper scraps and tobacco dust remaining on the drum roller.
[0039] like Figures 4-6As shown, this utility model also includes a drum cleaning device 20. Considering the space at the original drum, the drum cleaning device 20 can be installed on the upper right side of the drum, mounted on the original drum float adjustment rod, to blow away residual paper scraps and tobacco dust on the drum. Specifically, the drum cleaning device 20 includes a hollow adjustment rod 200 mounted on the drum float. This hollow adjustment rod 200 is a modified version of the original adjustment rod, a hollow shaft, used as the hollow adjustment rod 200 of this drum cleaning device 20. A second air inlet connector 201 is installed at the end of the hollow adjustment rod 200 furthest from the drum float. The second air inlet connector 201 is connected to an air source via a pipe. A drum blower corresponding to the filter section of the drum is installed in the middle of the hollow adjustment rod 200. The air block 202, and the side of the air block 202 near the approaching drum 4 is an arc-shaped surface coaxial with the approaching drum 4, so as not to affect the rotation of the approaching drum. The hollow adjusting rod 200 has an air groove 204 in the middle to guide the gas in the hollow adjusting rod 200 to the air block 202. Multiple air blowing ports are opened on both sides of the air block 202. When the approaching drum cleaning device 20 is started, it blows out airflow. The airflow direction is from the cigarette filter section of the cigarette group on the approaching drum to the cigarettes on both sides, carrying the cigarette dust out to the waste box. The blowing continues during the operation of the equipment and stops when the equipment stops.
[0040] like Figures 7-8 As shown, this utility model also includes a paper-jointing drum cleaning device 30. In the paper-jointing forming section, the original guide rail is an irregularly shaped arc-shaped block, which is installed on the left side of the joining drum and above the joining drum via two positioning rods on the wall plate of the assembly machine. Specifically, the paper-jointing drum cleaning device 30 includes a fixing block 300, a lifting plate 301, and a side-blowing block 302. The fixing block 300 is installed on the positioning rod 6 above the joining drum 5, and one side of the lifting plate 301 is installed on the fixing block 300. The other side of the 1 is positioned above the rubbing drum and tangent to the outer circle of the rubbing drum. The side blowing block 302 is installed on one side of the lifting plate 301, and the air outlet of the side blowing block 302 faces one side of the lifting plate 301. This allows the airflow blown out by the side blowing block 302 to clean the area above the rubbing drum and clean the surface of the rubbing drum. This cleans the water-soaked paper pieces and tobacco dust adhering to the rubbing drum, reduces the frequency of rubbing plate blockage, and reduces the quality defects of the mixed tobacco.
[0041] As a preferred embodiment of this invention, it should be further explained that the side blowing block 302 has an air chamber inside, and a third air inlet pipe connector 303 communicating with the air chamber is installed on one side of the side blowing block 302. The other end of the side blowing block 302 is provided with a plurality of small air blowing holes aligned with one side of the lifting plate 301. Thus, a stable high airflow can be blown out through the small air blowing holes, effectively cleaning the cork paper and tobacco dust sticking to the rubbing drum.
[0042] As a preferred embodiment of this invention, it should be further noted that the lifting plate 301 can be an L-shaped plate or an arc plate, and can be set according to the actual situation without any specific restrictions.
[0043] Preferably, one side of the lifting plate 301 is connected to the fixing block 300 by bolts, and one side of the fixing block 300 is provided with a connecting surface for connecting to the lifting plate 301. The connecting surface has threaded holes for threaded connection with the bolts. Figure 8 As shown, a long strip hole extending vertically is provided on one side of the lifting plate 301. The bolt shank passes through the long strip hole and is connected to the threaded hole. The bolt nut abuts against one side of the lifting plate 301, thereby adjusting the height of the lifting plate 301. That is, the distance between the lifting plate 301 and the rubbing drum 5 can be adjusted according to the actual situation.
[0044] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
