DETAILED DESCRIPTION

[0022] Those skilled in the art will understand the above advantages and other advantages and benefits of various embodiments after reading the following detailed description of the embodiments with reference to the listed drawings. According to common practice, the various components of the various figures discussed below are not necessarily drawn to scale. The sizes of different components and elements in the various figures may be enlarged or reduced to more clearly illustrate the embodiments of the utility model.

[0023] In order to improve the problem of inaccurate positioning or overturning of cigarette packages during transportation, the negative pressure adsorption area used to adsorb and hold cigarette packages on the conveyor belt is supplied with negative pressure in sections, so that the section with cigarette packages is supplied with negative pressure, while the section without cigarette packages is not supplied with negative pressure, thus reducing the problem of negative pressure leakage in the section without cigarette packages.

[0024] like Figure 1 As shown, the utility model provides a cigarette package conveyor line, including a conveyor belt 2, a negative pressure adsorption zone 3 and a gas distribution device 4. The conveyor belt 2 is used to convey cigarette packages 1. The negative pressure adsorption zone 3 includes a plurality of fixed negative pressure chambers, which are fixedly arranged in sequence along the conveying direction of the conveyor belt 2 and are adjacent to one side of the conveyor belt 2. The top surfaces of the plurality of negative pressure chambers are substantially flush with the top surface of the conveyor belt 2, so that the cigarette packages 1 can be held by means of negative pressure adsorption during the process of the conveyor belt 2 conveying the cigarette packages 1. The air distribution device 4 is connected to the negative pressure source, and is used to provide negative pressure to multiple negative pressure chambers in turn along the conveying direction. When the cigarette package 1 passes over multiple negative pressure chambers, negative pressure is only provided to a corresponding negative pressure chamber below the cigarette package 1, while no negative pressure is provided to other negative pressure chambers, so that there is always a negative pressure chamber that holds the cigarette package 1 by means of negative pressure adsorption. In this way, by supplying negative pressure to multiple negative pressure chambers in turn along the conveying direction, there is no negative pressure leakage, which reduces the situation where the negative pressure suction is insufficient and the cigarette package 1 cannot be adsorbed, thereby reducing the risk of overturning of the cigarette package 1.

[0025] In some embodiments, Figure 1As shown, a plurality of protrusions 21 are provided on the conveyor belt 2, the distance between two adjacent protrusions 21 is much larger than the size of the cigarette package box 1, and the negative pressure adsorption area 3 between two adjacent protrusions 21 is divided into a plurality of negative pressure chambers.

[0026] In some embodiments, Figure 2 As shown, the negative pressure adsorption area 3 includes the first to fourth negative pressure chambers 301-304, and the top surface of each negative pressure chamber is provided with a plurality of air holes 305, which are used to hold the cigarette package box 1 above by means of negative pressure adsorption, and the bottom of each negative pressure chamber is provided with a negative pressure interface. In this way, the cigarette package box 1 can be relatively evenly adsorbed on the entire top surface where the cigarette package box 1 contacts the negative pressure chamber, avoiding the occurrence of excessive local negative pressure.

[0027] In some embodiments, the air distribution device 4 includes an air distribution disk 412 provided with multiple airways, and the multiple airways can be switched to be connected to the negative pressure source in a selective manner. The multiple airways correspond one-to-one to the multiple negative pressure chambers. The multiple airways are connected to the corresponding negative pressure chambers through multiple air pipes, respectively, and when one of the airways is switched to be connected to the corresponding negative pressure chamber, the remaining airways are not connected to their respective corresponding negative pressure chambers.

[0028] In some embodiments, the gas distribution device 4 includes a rotatable gas distribution disk 407 connected to the negative pressure source, the gas distribution disk 407 is coaxially and connected to the gas distribution disk 412, and the entire circumferential area of ​​the gas distribution disk 407 is divided into multiple areas along the circumference, and the multiple areas correspond one by one to multiple airways. When one area of ​​the gas distribution disk 407 is rotated to be connected to the corresponding airway, the remaining areas are not connected to their respective corresponding airways. When the gas distribution disk 407 is rotated one circle, the multiple negative pressure chambers 301, 302, 303, and 304 are connected to their respective areas in turn.

[0029] In some embodiments, Figure 3 and 4 As shown, the gas distribution device 4 includes a gas supply disk 409, which is connected to the negative pressure source through an air pipe and is fixed. The gas supply disk 409 and the gas distribution disk 412 are coaxially and connectedly arranged on both sides of the gas distribution disk 407, respectively, and the negative pressure from the negative pressure source is sequentially provided to the negative pressure adsorption area 3 through the gas supply disk 409, the gas distribution disk 407 and the gas distribution disk 412.

[0030] In some embodiments, Figure 3 and 4As shown, since the gas distribution disk 407 rotates as an intermediate air chamber and is rotatably connected to the gas distribution disk shaft 410, in order to avoid negative pressure leakage between the gas supply disk 409 and the gas distribution disk 407, and between the gas distribution disk 412 and the gas distribution disk 407, an air supply disk graphite sheet 408 is arranged between the gas supply disk 409 and the gas distribution disk 407, and a gas distribution disk graphite sheet 406 is arranged between the gas distribution disk 407 and the gas distribution disk 412. The gas distribution disk 407 rotates while the graphite sheet remains stationary, so that the graphite sheet becomes smoother and smoother, and the gas distribution disk 407 and the graphite sheet become closer to each other, thereby reducing the risk of negative pressure leakage caused by the rotation of the gas distribution disk 407.

[0031] In some embodiments, Figure 4 As shown, a mounting plate 403 is coaxially arranged outside the gas distribution plate 412 and the gas supply plate 409, and springs 405 are respectively arranged between the gas distribution plate 412 and the mounting plate 403 and between the gas supply plate 409 and the mounting plate 403. Since the two mounting plates 403 are fixedly mounted on the bottom plate 401, the springs 405 push the gas distribution plate 412 and the gas supply plate 409 toward the gas distribution plate 407, thereby reducing the risk of negative pressure leakage.

[0032] In some embodiments, Figure 5 and 6As shown, the gas distribution disk 412 is provided with first to fourth air passages 4121-4124, and the gas distribution disk 407 is divided into first to fourth areas along the circumferential direction. When the gas distribution disk 407 rotates to 0-90 degrees, the first area of ​​the gas distribution disk 407 is connected to the first air passage 4121 on the gas distribution disk 412, and the second to fourth areas of the gas distribution disk 407 and the second to fourth air passages 4122-4224 on the gas distribution disk 412 are in a truncated state; when the gas distribution disk 407 rotates to 90-180 degrees, the second area of ​​the gas distribution disk 407 is connected to the second air passage 4122 of the gas distribution disk 412, and the first, third and fourth areas of the gas distribution disk 407 are connected to the second air passage 4122 of the gas distribution disk 412. The four regions are in a cut-off state with the first, third and fourth air passages of the gas distribution disk 412; when the gas distribution disk 407 rotates to 180-270°, the third region of the gas distribution disk 407 is connected with the third air passage 4123 on the gas distribution disk 412, while the first, second and fourth regions of the gas distribution disk 407 are in a cut-off state with the first, second and fourth air passages of the gas distribution disk 412; when the gas distribution disk 407 rotates to 270-360°, the fourth region is connected with the fourth air passage on the gas distribution disk 412, while the first, second and third regions of the gas distribution disk 407 are in a cut-off state with the first, second and third air passages on the gas distribution disk 412. Thus, the first to fourth air passages on the gas distribution disk 412 are connected with the four negative pressure interfaces in the negative pressure chamber 3 in turn through the air pipe, so as to realize the segmented air supply to the four negative pressure chambers. The negative pressure adsorption area 3 between two adjacent protrusions 21 is divided into four negative pressure chambers 301-304, and the four negative pressure chambers 301-304 are connected to the first, second, third and fourth air channels 4121-4124 of the gas distribution plate 412 through air pipes respectively.

[0033] In some embodiments, the cigarette packaging box conveyor line includes a servo motor 10, a first pulley 5 and a second pulley 7. The first pulley 5 is connected to the motor 10 for driving and rotating the gas distribution device 4; the second pulley 7 is connected to the motor 10 for driving and rotating the conveyor belt 2; the negative pressure adsorption area 3 between two adjacent protrusions 21 is divided into multiple negative pressure chambers, and the gas distribution disk 407 of the gas distribution device 4 is rotated one circle, and the multiple negative pressure chambers between the two adjacent protrusions 21 are connected to the negative pressure in turn one circle, and the conveyor belt 2 transports the cigarette packaging box 1 a distance corresponding to the multiple negative pressure chambers 301, 302, 303, and 304, thereby realizing the synchronous cooperative action of the gas distribution device 4, the multiple negative pressure chambers and the conveyor belt 2.

[0034] In some embodiments, since cigarette packages of different specifications need to be adsorbed and held, the negative pressure needs to be adjusted to accommodate cigarette packages of different specifications, and thus the negative pressure provided to the negative pressure adsorption area 3 is adjustable.

[0035] The utility model also provides a cigarette production line, comprising the cigarette packaging box conveying line.
