Description

Technical Field

[0001] The utility model relates to the technical field of cigarette production, and particularly relates to a cleaning device. Background Art

[0002] During the process of cigarette production, due to mechanical reasons such as vibration and cigarette magazine blockage during the belt transmission of cigarette rods in the tipping and packaging production lines, the filter tips on the finally produced cigarette rods may be missing. To ensure the quality of cigarette rods, a filter tip imaging detection mechanism is usually installed on the cigarette production line to detect whether there is a defect of missing filter tips on the cigarette rods.

[0003] After the filter tips are assembled into cigarette rods, they are conveyed through a conveying channel to the filter tip imaging detection mechanism. The filter tip imaging detection mechanism is usually arranged on one side of the conveying channel and faces the filter tip end of the cigarette rod. Currently, during the production process, the filter tip imaging detection mechanism often misremoves qualified cigarette rods, resulting in waste. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the technical problem that the filter tip imaging detection mechanism is prone to misremoving qualified cigarette rods. The utility model provides a cleaning device, which can reduce the situation that the filter tip imaging detection mechanism is prone to misremoving qualified cigarette rods, thereby reducing waste and lowering costs.

[0005] To solve the above technical problems, the inventor explored and found that the main reason why the filter tip imaging detection mechanism is prone to misremoving qualified cigarette rods currently is that: in some new cigarettes, a binary paper tube composite filter tip is used, and there is a cavity at the front end of the filter tip. When the cigarette rod with the binary paper tube composite filter tip runs in the conveying channel, some tobacco dust will enter the cavity on the filter tip. When the cigarette rod runs to the filter tip imaging detection mechanism, the filter tip imaging detection mechanism cannot recognize the filter tip, and it is easy to mistake the filter tip section for the cigarette rod section, resulting in the filter tip imaging detection mechanism misremoving the qualified cigarette rod as a defective cigarette rod lacking a filter tip, causing the qualified cigarette rod to be misremoved.

[0006] An embodiment of the utility model provides a cleaning device for cleaning the filter tip of a cigarette rod. There is a cavity in the filter tip. The cigarette rod is conveyed along a conveying channel, and the conveying channel extends along a first direction. The cleaning device includes:

On the contrary, the purpose of introducing the utility model in conjunction with the implementation manner is to cover other alternatives or modifications that may be extended based on the claims of the present utility model.

[0029] In the description of this embodiment, it should also be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "coupled" should be understood in a broad sense.

For those of ordinary skill in the art, the specific meanings of the above terms in this embodiment can be understood according to specific situations.

[0030] Currently, after the filter tip is assembled into a cigarette, it is conveyed by a conveying channel to the filter tip imaging detection mechanism. The filter tip imaging detection mechanism is arranged on one side of the conveying channel and is oriented towards the filter tip end of the cigarette. During the production process, there often occurs a phenomenon that the filter tip imaging detection mechanism mistakenly rejects qualified cigarettes, resulting in waste.

[0031] To solve the above technical problems, the inventors explored and found that the main reason why the filter tip imaging detection mechanism is prone to erroneously rejecting qualified cigarette sticks is as follows: In some new types of cigarettes, a binary paper tube composite filter tip is used, and there is a cavity at the front end of the filter tip. When a cigarette stick with a binary paper tube composite filter tip runs in the conveying channel, some tobacco dust will enter the cavity on the filter tip. As a result, when the cigarette stick runs to the filter tip imaging detection mechanism, the filter tip imaging detection mechanism cannot recognize the filter tip and is prone to misidentifying the filter tip section as the cigarette stick section, causing the filter tip imaging detection mechanism to erroneously regard a qualified cigarette stick as a defective cigarette stick lacking a filter tip and resulting in the erroneous rejection of qualified cigarette sticks.

[0032] The present utility model provides a cleaning device, which can reduce the situation where the filter tip imaging detection mechanism is prone to erroneously rejecting qualified cigarette sticks, thereby reducing waste and lowering costs.

[0033] To make the technical solution and advantages of the present utility model clearer, the following further describes the embodiments of the present utility model in detail.

[0034] Referring to Figure 1 and Figure 2 , the embodiment of the present utility model provides a cleaning device, including a main body 1, a group of air blowing holes and a suction groove 3. The main body 1 extends along a first direction (such as the X direction shown in Figure 1 ) and is located on one side of the conveying channel 4. The side of the main body 1 close to the conveying channel 4 is a working surface 11, and the working surface 11 faces the filter tip end of the cigarette stick. The group of air blowing holes is arranged on the working surface 11. The group of air blowing holes includes a plurality of air blowing holes 2 arranged at intervals along the first direction. The air blowing holes 2 are used to blow air into the cavity of the filter tip. The suction groove 3 is arranged on the working surface 11 and extends along the first direction. The opening of the suction groove 3 faces the conveying channel 4. The suction groove 3 is connected to a negative pressure air source. Specifically, referring to Figure 1 , the main body 1 is further provided with a negative pressure air source access hole 8. The negative pressure air source access hole 8 is respectively connected to the two suction grooves 3. The negative pressure air source access hole 8 is used to connect the negative pressure air source and the suction groove 3.

[0035] Figure 2 shows a top view of the conveying channel 4. Referring to Figure 2 , in this embodiment, the cleaning device 14 is located upstream of the filter tip imaging detection mechanism 5. As shown in Figure 2 , the cigarette sticks output from the cigarette magazine 13 are conveyed in the conveying channel 4 towards a preset working station. The conveying direction of the cigarette sticks is as shown in Figure 2As shown in the N direction in the figure, the cigarette rod first passes through the cleaning device 14 and then through the filter tip imaging detection mechanism 5. When the cigarette rod located in the conveying channel 4 runs to the cleaning device 14, the air blowing holes 2 on the main body 1 can blow air towards the cigarette rod to blow out the tobacco dust in the filter tip cavity. Subsequently, the suction groove 3 sucks the blown tobacco dust into the suction groove 3 to prevent the tobacco dust from falling into the filter tip cavity again. By providing the air blowing holes 2 and the suction groove 3, the utility model can clean the tobacco dust in the filter tip of the cigarette rod, so that the filter tip imaging detection mechanism 5 can correctly identify the filter tip, thereby preventing qualified cigarette rods from being mis-rejected by the filter tip imaging detection mechanism 5, reducing waste and lowering costs.

[0036] Optionally, referring to Figure 1 , the number of the suction grooves 3 and the air blowing hole groups is at least two, and each suction groove 3 and each air blowing hole group are alternately arranged in the vertical direction (as shown in the Y direction in Figure 1 the figure). Exemplarily, the number of the suction grooves 3 and the air blowing hole groups is equal, and each suction groove 3 is respectively located below each air blowing hole group. When the air blowing hole group blows up the tobacco dust in the filter tip, the tobacco dust suspended in the air will settle under the action of gravity. By arranging the suction groove 3 below the air blowing hole group, the cleaning effect on the settled tobacco dust can be improved. In this embodiment, the number of both the suction grooves 3 and the air blowing hole groups is two. Since the conveying channel 4 usually transports two rows of cigarette rods at a time, by providing two suction grooves 3 and two air blowing hole groups respectively, the utility model can make each suction groove 3 and each air blowing hole group correspond to one row of cigarette rods in the conveying channel 4 respectively, so that the tobacco dust in the filter tip of each row of cigarette rods can be removed.

[0037] Optionally, referring to Figure 4 , two positive pressure air conveying channels 6 extending in the first direction are provided inside the main body 1. One end of the positive pressure air conveying channel 6 is closed, and the other end is connected to a positive pressure air source.
