Description

Technical Field

[0001] This utility model belongs to the field of cigarette machine technology, specifically relating to a cigarette rejection device for cigarette machines. Background Technology

[0002] The ZJ118 and ZJ17 cigarette production lines are the mainstream equipment in cigarette production lines and are widely used in major cigarette factories. During high-speed operation, the ZJ118 and ZJ17 cigarette production lines have a probability of producing defective products due to factors such as the operating environment and tobacco structure. Therefore, image sensors are used to detect the appearance of the cigarettes, and rejecters are installed on the rejecting drum to remove defective products.

[0003] When the rejection drum removes a large number of cigarettes, the continuous rejection action may cause insufficient air pressure on the rejection drum. The cigarettes are not adsorbed stably on the rejection drum, resulting in flying smoke. Cigarettes that are not adsorbed in the smoking trough fly around, causing the rejection drum and receiving drum to be crushed. They are then directly mixed into the finished cigarettes, which poses a quality risk. Utility Model Content

[0004] The purpose of this invention is to provide a cigarette rejection device for cigarette machines, which solves the problem that when existing cigarette machines remove a large amount of cigarettes, the air pressure used for cigarette adsorption becomes unstable, causing cigarette backflow, which in turn affects the quality of cigarette production in subsequent processes.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A cigarette rejection device for a cigarette rolling machine includes a frame and a rejection drum and a receiving drum rotatably mounted on the frame. The rejection drum and the receiving drum are coupled, and the rejection drum rejects cigarettes and transfers any unrejected cigarettes to the receiving drum. A mounting frame is mounted on the frame, and a baffle is mounted on the mounting frame. The top of the baffle extends below the side of the rejection drum near the receiving drum to intercept cigarettes that have detached from the rejection drum.

[0007] The overall structure of this application is simple and highly practical. Based on the existing cigarette machine, only a baffle needs to be installed through the mounting frame to block and intercept the swirling or flying smoke caused by unstable air pressure when the rejection drum removes cigarettes. This avoids the phenomenon of cigarettes being crushed due to the unstable adsorption of cigarettes by the rejection drum, and thus prevents defective cigarettes from entering subsequent processes and affecting the production quality of cigarettes.

[0008] Furthermore, the mounting frame is provided with a material guide channel in the middle, the top of the material guide channel is located below the baffle, and the bottom of the material guide channel is connected to a cigarette recycling end.

[0009] Further limited, the mounting frame is opened with a hanging hole away from one side of the rack; the bottom of the mounting frame is sleeved with a recycling frame, the outer side of the recycling frame is connected with a side plate, the top of the side plate is connected with a hanging nail, the hanging nail is clamped into the hanging hole to detachably hang the recycling frame, the recycling frame is connected with the material falling gap opened on the material guide channel, and the recycling end of the cigarette is formed.

[0010] Wherein, the cooperation of the hanging hole and the hanging nail is simple in structure, convenient to disassemble and replace, so as to facilitate the reprocessing and utilization of the recycled cigarettes.

[0011] Further limited, the mounting frame is opened with a connecting hole near one side of the rack, the connecting hole is connected with the rack through a screw; the top of the mounting frame is formed with an inclined mounting surface, the mounting surface is opened with a mounting hole, and the mounting hole is connected with the baffle through a screw.

[0012] Further limited, the top surface of the mounting frame is provided with two opposite limiting clamping plates, the opposite sides of the two limiting clamping plates are provided with limiting grooves, and the baffle is inserted into the limiting grooves.

[0013] Further limited, the top surface of the mounting frame is opened with an adjusting hole, an adjusting bolt is installed in the adjusting hole, the adjusting bolt abuts against the bottom of the baffle, and the adjusting bolt is used for adjusting the insertion depth of the baffle.

[0014] Further limited, the top surface of the mounting frame is provided with a limiting frame, the limiting frame is formed with a limiting cavity toward one side of the ejecting drum, and the baffle is inserted into the limiting cavity.

[0015] Further limited, the baffle comprises two segments of the material blocking segment and the limiting segment which are stacked and connected, a limiting edge is formed at the folding position of the material blocking segment and the limiting segment, and the limiting edge abuts against the top end surface of the mounting frame.

[0016] Wherein, by cooperating the limiting edge with the top end surface of the mounting frame, the baffle can be installed without using screws, and the baffle can be conveniently repaired and replaced without disassembling the screws.

[0017] Further limited, the baffle is connected with an arc plate near one end of the ejecting drum, and the inner arc surface of the arc plate faces downward.

Specific implementation

[0037] The utility model will be explained in detail in combination with the drawings and specific embodiments, and it should be explained that, in the drawings or the description, similar or same parts all use same figure number, and the implementation mode not drawn or described in the drawings is the form known by the ordinary skilled in the art. In addition, the direction language mentioned in the embodiment, for example, "up", "down", "top", "bottom", "left", "right", "front", "back" and the like, is only the direction of the drawings, and is not used to limit the protection scope of the utility model.

[0038] As Figure 1 , Figure 2As shown, the cigarette machine cigarette removing device of the utility model embodiment, including frame 13 and rotating installation frame 13 on the removing drum 10 and receiving drum 40 of removing drum 10;Wherein, the rotating installation of removing drum 10, receiving drum 40 and frame 13, can be realized by bearing;Generally, the structure of removing drum 10 and receiving drum 40 is basically same, and the size is different, the outer circumferential surface of removing drum 10 and receiving drum 40 is provided with suction slot 11, each suction slot 11 is provided with two air holes 12, and the suction slot 11 in removing drum 10 is transmitted to the suction slot 11 in receiving drum 40, that is, coupling;When the next suction slot 11 of removing drum 10 has no cigarette, it is still butted with the next suction slot 11 of receiving drum 40, but does not transmit cigarette;Wherein, the condition that removing drum 10's suction slot 11 has no cigarette, can be removed by cigarette.

[0039] In the embodiment, the air hole 12 is connected with the positive pressure gas pipeline and the negative pressure gas pipeline, and the positive pressure gas pipeline and the negative pressure gas pipeline are connected with the air pump; the connection of the positive pressure gas pipeline, the negative pressure gas pipeline and the air hole 12 can be switched by the valve, so that the suction slot 11 adsorbs the cigarette by negative pressure, and the cigarette in the suction slot 11 is discharged by positive pressure.

[0040] In the embodiment, the removing drum 10 removes the cigarette and transmits the cigarette not removed to the receiving drum 40; the mounting frame 20 is installed on the frame 13, the baffle 30 is installed on the mounting frame 20, the top of the baffle 30 extends to the lower side of the removing drum 10 close to the receiving drum 40, so as to intercept the cigarette separated from the removing drum 10; the extension direction of the baffle 30 can be along the radial direction of the removing drum 10 and align with the center of the removing drum 10. During the process that the cigarette not removed is transmitted to the receiving drum 40 by the removing drum 10, the baffle 30 does not affect the rotation of the removing drum 10 and the receiving drum 40. Such structure design is relatively simple, low in cost and high in practicability; it is especially suitable for the cigarette turning (or flying) phenomenon of the removing drum 10, and the flying cigarette is intercepted because the centrifugal force of the rotating transmission of the removing drum 10 makes the flying cigarette fly to the receiving drum 40, even enters the coupling position of the removing drum 10 and the receiving drum 40, resulting in that the cigarette is crushed; the crushed cigarette may enter the next process; the baffle 30 can avoid such flying cigarette influence and improve the production quality of the cigarette.

[0041] In order to reduce the installation and replacement difficulty of the mounting frame 20, such as Figure 3As shown, three connecting holes 21 are formed on the side of the mounting frame 20 close to the rack 13, and the mounting frame 20 can be connected to the rack 13 through two or three connecting holes 21 and screws. An inclined mounting surface 22 is formed on the top of the mounting frame 20, and a mounting hole 23 is formed on the mounting surface 22 and connected to the baffle 30 through a screw. A fixing hole 31 corresponding to the mounting hole can be formed on the baffle 30. As shown, Figure 10 As shown,

[0042] In fact, other fixing modes of the baffle 30 can also be selected according to actual needs. In the embodiment, the baffle can also be welded to the mounting surface or inserted into the mounting surface. As shown, Figure 13 As shown,

[0043] As shown, Figure 4 , Figure 13 As shown, the top surface of the mounting frame of the embodiment is provided with two opposite limiting clamping plates 25, and the opposite sides of the two limiting clamping plates 25 are provided with limiting grooves 24, and the baffle 30 is inserted into the limiting grooves 24. Such a structure design can realize the limiting installation of the baffle 30 without the need for screws, and can be more conveniently disassembled and replaced when the baffle 30 needs to be replaced.

[0044] In fact, other limiting modes of other structures can also be selected according to the design strength requirements. For example, an adjusting hole 26 is formed on the top surface of the mounting frame 20, and three adjusting holes 26 are obliquely arranged to form three gears. An adjusting bolt is installed in the adjusting hole 26 during use, the bottom of the baffle 30 abuts against the adjusting bolt, the bottom of the baffle 30 is limited by the adjusting bolt, and the insertion depth of the baffle 30 is adjusted by the adjusting bolt. In this way, it is suitable for different cigarette specifications. Because the specifications of cigarettes are different, the diameters of cigarettes may also be different. The gap between the baffle 30 and the rejecting drum 10 needs to be left during rejecting and conveying, and the gap can be adjusted by adjusting the insertion depth of the baffle 30. As shown, Figure 5 For another example, a limiting frame 27 is arranged on the top surface of the mounting frame 20, and a limiting cavity 28 is formed on the side of the limiting frame 27 facing the rejecting drum 10, and the baffle 30 is inserted into the limiting cavity 28. Its structure is shown in Figure 6 As shown,

[0045] During actual use, a certain thickness of a pad can be laid on the bottom of the limiting cavity 28 to adjust the insertion depth of the baffle 30. In this way, different setting modes are formed with the adjusting bolt, and the adaptability and practicability of the device can be flexibly selected as needed.

[0046] In the embodiment, as shown, Figure 7As shown, the mounting rack 20 is a housing structure, and when in use, the cigarettes are intercepted by the baffle 30, and then fall from the mounting rack 20. Therefore, a guide channel can be arranged in the middle of the mounting rack 20, the top of the guide channel is below the baffle 30, and the bottom of the guide channel is connected with the cigarette recovery end.

[0047] In this embodiment, as shown in the drawings, a material falling gap 210 can be arranged on the guide channel to perform material falling and cigarette recovery. The recovery period and method can be designed as required. When designing, a hanging hole 29 can be arranged on the side of the mounting rack 20 away from the rack 13; a recovery frame 50 is sleeved on the bottom of the mounting rack 20, the outer side of the recovery frame 50 is connected with a side plate 51, the top of the side plate 51 is connected with a hanging nail 52, the hanging nail 52 is clamped into the hanging hole 29, so that the recovery frame 50 is detachably hung and installed, the recovery frame 50 is connected with the material falling gap 210 arranged on the guide channel, and the cigarette recovery end is formed. Figures 7 to 9 In this embodiment, as shown in the drawings, the baffle 30 includes two segments of the material blocking segment 32 and the limiting segment 33 which are laminated and connected, and the folding part of the material blocking segment 32 and the limiting segment 33 forms a limiting edge 34, and the limiting edge 34 abuts against the top end face of the mounting rack 20.

[0048] Figure 11 In this embodiment, as shown in the drawings, the baffle 30 is connected with an arc plate 35 near one end of the rejection drum 10, and the inner arc surface of the arc plate 35 faces downward. Such a structure design, while the baffle 30 extends to one side of the rejection drum 10; the inner arc surface of the arc plate 35 can guide the cigarettes intercepted by the baffle 30, so that the cigarettes fall more smoothly, and the vertical impact of the cigarettes on the baffle 30 can be reduced, and the stability of the structure is improved.

[0049] Such a structure design, on the basis of the existing cigarette making machine, a baffle 30 is arranged below the rejection drum 10 and the receiving drum 40 through the mounting rack 20, the top of the baffle 30 extends to one side of the rejection drum 10, but does not contact the rejection drum 10, and does not affect the rotation of the rejection drum 10 and the receiving drum 40, and normal cigarette rejection and transmission are performed; when the rejection drum 10 rejects defective cigarettes, there may be a large amount of rejection, which may cause unstable adsorption air pressure of the rejection drum 10 on the cigarettes, the baffle 30 can intercept the cigarettes which are not completely adsorbed, cut off the cigarettes, does not affect the transmission and reception of the normally adsorbed cigarettes, and improves the production quality of the cigarettes; and the overall structure is simple and has high practicability.
