[0036] Referring to Figures 1-6 The present embodiment provides a cigarette buffer device, which comprises a rack, a tobacco bin 1 and an adjusting mechanism 2. The cigarette buffer device can ensure the consistency of the width adjustment of the tobacco bin 1, facilitate adjustment, and has high adjustment accuracy, so that the tobacco bin 1 can be adapted to more specifications of cigarettes, and has strong versatility.

[0037] The tobacco bin 1 is arranged on the rack, and the tobacco bin 1 comprises first bin plates 11 and second bin plates 12 which are oppositely arranged and have an adjustable spacing, and the tobacco bin 1 is configured to buffer cigarettes. The adjusting mechanism 2 comprises a plurality of first adjusting rods 21 and a transmission assembly 22.

The plurality of first adjusting rods 21 are distributed along the extension direction of the first bin plate 11 and the second bin plate 12. The transmission assembly 22 is in transmission connection with the plurality of first adjusting rods 21. Driving any first adjusting rod 21 can drive the transmission assembly 22 to synchronously rotate the plurality of first adjusting rods 21, so as to adjust the spacing of the first bin plate 11 and the second bin plate 12.

[0038] The cigarette buffer device provided by the present embodiment can adjust the width of the tobacco bin 1. Since the plurality of first adjusting rods 21 are in transmission connection through the transmission assembly 22, driving any first adjusting rod 21 can drive the transmission assembly 22 to synchronously rotate the plurality of first adjusting rods 21, so that the plurality of first adjusting rods 21 synchronously adjust the spacing of the first bin plate 11 and the second bin plate 12, and the adjustment is convenient. The synchronous action of the plurality of first adjusting rods 21 realizes multi-point synchronous adjustment of the width of the tobacco bin 1, improves the stability of the width adjustment, and especially for the first bin plate 11 and the second bin plate 12 which are relatively long, the synchronous rotation of the plurality of first adjusting rods 21 driven by the transmission assembly 22 ensures the consistency of the width adjustment of the tobacco bin 1, improves the adjustment accuracy of the width of the tobacco bin 1, and makes the cigarette buffer device be able to adapt to various specifications of cigarettes, thereby improving the distribution efficiency of the cigarettes.

[0039] The structural design of the above-mentioned cigarette buffer device is suitable for the width adjustment of horizontal tobacco bins, vertical tobacco bins, horizontal-vertical combined tobacco bins and similar tobacco bins, and can ensure the consistency of the width adjustment of the tobacco bin 1.

The first adjusting rod 21 is rotationally connected with the first bin plate 11 and the second bin plate 12 through the threaded connection, which can drive the first bin plate 11 and / or the second bin plate 12 to slide relative to the rack while the first adjusting rod 21 rotates, so as to adjust the distance between the first bin plate 11 and the second bin plate 12. Meanwhile, the threaded connection is stable and convenient to assemble and disassemble. Optionally, the first adjusting rod 21 is a positive and negative toothed screw rod.

[0041] Optionally, the rack is provided with a track along the first direction, the first direction is perpendicular to the extending direction of the first bin plate 11 and the second bin plate 12, and the first bin plate 11 and / or the second bin plate 12 are provided with a sliding part 111 (as shown in Figure 2 The structure realizes the sliding connection between the first bin plate 11 and / or the second bin plate 12 and the rack. When the first adjusting rod 21 is screwed, the first bin plate 11 and / or the second bin plate 12 slide along the track through the sliding part 111, so as to adjust the distance between the first bin plate 11 and the second bin plate 12.

[0042] Further, in the embodiment, the first bin plate 11 and the second bin plate 12 are both slidably arranged on the rack, and correspondingly, the first bin plate 11 and the second bin plate 12 are both provided with a sliding part 111. Since the rotation directions of the first thread section and the second thread section are opposite, the first bin plate 11 and the second bin plate 12 can be driven to approach or move away from each other along the first direction by screwing the first adjusting rod 21, so as to adjust the distance between the first bin plate 11 and the second bin plate 12. The first bin plate 11 and the second bin plate 12 are both slidably arranged on the rack, which can shorten the sliding distance of the first bin plate 11 and the second bin plate 12 and improve the adjustment efficiency. In the embodiment, referring to Figure 2 , the sliding part 111 is a groove arranged at the lower part of the first bin plate 11 and the second bin plate 12.

[0043] In other embodiments, one of the first bin plate 11 and the second bin plate 12 can be slidably connected with the rack, and the other can be fixedly connected with the rack, as long as the distance between the two can be adjusted.

[0044] For the convenience of description, the extending direction of the first bin plate 11 and the second bin plate 12 is defined as the second direction, and in the embodiment, the first direction is the width direction of the tobacco bin 1, and the second direction is the length direction of the tobacco bin 1.

[0045] Optionally, referring to Figure 1 and Figure 4 , the adjusting mechanism 2 further comprises a plurality of second adjusting rods 23, one end of each of the plurality of second adjusting rods 23 is rotationally connected with the first bin plate 11, and the other end of each of the plurality of second adjusting rods 23 is rotationally connected with the second bin plate 12, the plurality of second adjusting rods 23 and the plurality of first adjusting rods 21 are sequentially staggered and spaced along the extending direction of the first bin plate 11 and the second bin plate 12, the transmission assembly 22 is transmissionally connected with the plurality of second adjusting rods 23, and driving any first adjusting rod 21 or any second adjusting rod 23 can make the transmission assembly 22 drive the plurality of first adjusting rods 21 and the plurality of second adjusting rods 23 to synchronously and reversely rotate. The sequentially staggered and spaced arrangement of the plurality of second adjusting rods 23 and the plurality of first adjusting rods 21 can balance the force between the first adjusting rod 21 and the transmission assembly 22 and the force between the second adjusting rod 23 and the transmission assembly 22 when driving any first adjusting rod 21 or any second adjusting rod 23 to rotate, so that the transmission assembly 22 is balanced in force, the stability of the transmission of the transmission assembly 22 is improved, vibration is reduced, and the transmission efficiency is improved.

[0046] Further, the two ends of the second adjusting rod 23 are respectively provided with a third threaded section and a fourth threaded section, the third threaded section has an opposite rotation direction to the first threaded section, and the fourth threaded section has an opposite rotation direction to the second threaded section, the first bin plate 11 is provided with a third threaded hole, the second bin plate 12 is provided with a fourth threaded hole, the third threaded section is screwed into the third threaded hole, and the fourth threaded section is screwed into the fourth threaded hole, so that the two ends of the second adjusting rod 23 are respectively rotationally connected with the first bin plate 11 and the second bin plate 12. That is, the second adjusting rod 23 is provided with the third threaded section and the fourth threaded section having opposite rotation directions, so that rotating any second adjusting rod 23 can drive the first bin plate 11 and the second bin plate 12 to move close to or away from each other. Although the first adjusting rod 21 and the second adjusting rod 23 synchronously and reversely rotate, the first bin plate 11 and the second bin plate 12 can also synchronously move close to or away from each other due to the opposite rotation directions of the third threaded section and the first threaded section and the opposite rotation directions of the fourth threaded section and the second threaded section, so that the consistency of the width adjustment of the tobacco bin 1 is ensured. Optionally, the second adjusting rod 23 is a positive and negative toothed screw rod.

[0047] Optionally, referring to Figure 5The first connecting plate 113 and the second connecting plate 121 are respectively arranged on the side of the first bin plate 11 and the second bin plate 12 facing each other, the first threaded hole is arranged on the first connecting plate 113, and the second threaded hole is arranged on the second connecting plate 121. The third connecting plate and the fourth connecting plate 122 are respectively arranged on the side of the first bin plate 11 and the second bin plate 12 facing each other, the third threaded hole is arranged on the third connecting plate, and the fourth threaded hole is arranged on the fourth connecting plate 122. Since the thickness of the first bin plate 11 and the second bin plate 12 is usually small, it is not suitable to directly open the threaded hole on the first bin plate 11 and the second bin plate 12. In the embodiment, the first connecting plate 113 and the third connecting plate are arranged on the first bin plate 11, the second connecting plate 121 and the fourth connecting plate 122 are arranged on the second bin plate 12, and the threaded hole is arranged on the four connecting plates (at this time, only the through hole opposite to the threaded hole needs to be arranged on the first bin plate 11 and the second bin plate 12), so that the thickness of the connection part between the first bin plate 11 and the second bin plate 12 and the first adjusting rod 21 and the second adjusting rod 23 is locally increased, thereby improving the stability of the threaded connection, and further stably driving the first bin plate 11 and the second bin plate 12 to move close to or away from each other. At the same time, the existence of the four connecting plates can avoid damaging the opening part of the first bin plate 11 and the second bin plate 12 due to the frequent threaded screwing of the threaded segment and the threaded hole, prolonging the service life of the bin 1.

[0048] Optionally, the first connecting plate 113 and the second connecting plate 121 are respectively detachably connected to the first bin plate 11 and the second bin plate 12 by bolts, and the third connecting plate and the fourth connecting plate 122 are respectively detachably connected to the first bin plate 11 and the second bin plate 12 by bolts. The bolt connection is convenient to assemble and disassemble, and stable in connection.

[0049] Optionally, referring to Figure 1 , Figure 3 and Figure 4The transmission assembly 22 comprises a transmission chain 221, a first sprocket 222 and a second sprocket 223.

That is, the first sprocket 222 and the second sprocket 223 are engaged with the two sides of the transmission chain 221 oppositely (in this embodiment, the first sprocket 222 is engaged with the first engaging tooth on the lower side of the transmission chain 221, and the second sprocket 223 is engaged with the second engaging tooth on the upper side of the transmission chain 221), so that driving any one of the first adjusting rod 21 or the second adjusting rod 23 can synchronously drive the first adjusting rod 21 and the second adjusting rod 23 to rotate reversely. Meanwhile, such arrangement can also increase the meshing angle of the transmission chain 221 with the first sprocket 222 and the second sprocket 223, prevent tooth skipping, and improve the accuracy of adjustment. Meanwhile, chain transmission is reliable and has high transmission efficiency, and can adapt to complex working environment.

[0050] Preferably, the transmission chain 221 is an integral molded part, which has a row of first engaging teeth arranged on the lower side and a row of second engaging teeth arranged on the upper side.

At the same time, the ring-shaped transmission structure makes the structure of the transmission assembly 22 more compact, and further improves the stability of the transmission.

[0055] In an alternative embodiment, the two rows of first adjusting rods 21 and second adjusting rods 23 described above can also be synchronously driven and connected through an open-loop transmission chain 221. Specifically, the upper row of first adjusting rods 21 and second adjusting rods 23 are connected through one transmission chain 221, and the lower row of first adjusting rods 21 and second adjusting rods 23 are connected through another transmission chain 221.
