[0030] In combination Figure 1 As shown, the push plate mechanism provided by the embodiment is arranged in the cigarette box pushing and extending mechanism, which is used to push the cigarette box, so that the cigarette box completes the transition connection between the cigarette box shaping device and the cigarette box pushing and extending mechanism, thereby reducing the probability of causing indentation or damage to the bottom of the cigarette box by the cigarette box push plate 100, and ensuring the appearance quality of the cigarette box. Specifically, the push plate mechanism includes a cigarette box push plate 100 and a rolling friction assembly 200, the cigarette box push plate 100 is connected to the cigarette box pushing and extending mechanism through a connecting piece; the rolling friction assembly 200 includes a rolling roller 210, the rolling roller 210 is rotationally arranged on the cigarette box push plate 100, and the rolling roller 210 can roll with the cigarette box when the cigarette box shaping device and the cigarette box pushing and extending mechanism are transitionally connected.
[0031] Since the cigarette box pusher plate 100 is rotatably equipped with a rolling roller 210, and the cigarette box pusher plate 100 is set after the cigarette box pushing extension mechanism, when the cigarette box pusher plate 100 pushes the cigarette box, the cigarette box shaping device and the cigarette box pushing extension mechanism complete the transition connection through chain drive under the drive of the cigarette box pusher plate 100. At the moment of transition connection, the movement trajectory of the cigarette box pusher plate 100 under the traction of the chain drive is arc-shaped. At this time, the rolling roller 210 contacts the surface of the cigarette box before the cigarette box pusher plate 100. Then the rolling roller 210 is subjected to force and begins to roll, thereby avoiding the cigarette box pusher plate 100 from contacting the surface of the cigarette box, so as to reduce the probability of the cigarette box pusher plate 100 causing indentation or damage to the bottom of the cigarette box and ensuring the appearance quality of the cigarette box.
[0032] Preferably, the cigarette box push plate 100 is provided with a relief groove 110, and the rolling friction assembly 200 further includes a mounting shaft 220. The mounting shaft 220 is connected to the cigarette box push plate 100 corresponding to the relief groove 110, and the mounting shaft 220 extends along the A direction. The rolling roller 210 is rotatably disposed on the mounting shaft 220, and part of the rolling roller 210 is placed in the relief groove 110.
[0033] Combination Figure 1 As shown, the rolling roller 210 is connected to the cigarette box push plate 100 via the mounting shaft 220 to improve the connection strength and stability of the rolling roller 210. Simultaneously, as the operating time of the rolling roller 210 increases, when wear occurs, the rolling roller 210 can be replaced simply by removing the mounting shaft 220, making the operation convenient and quick, and improving overall maintenance efficiency. Since part of the rolling roller 210 is placed within the clearance groove 110, it ensures that the rolling roller 210 can roll and engage with the bottom surface of the cigarette box while reducing the volume of the rolling roller 210 exposed on the side of the cigarette box push plate 100 closest to the cigarette box. This avoids damage to other areas of the cigarette box surface due to excessive distance between the rolling roller 210 and the cigarette box push plate 100 during rolling and engaging with the bottom surface of the cigarette box, further ensuring the appearance quality of the cigarette box.
[0034] In some other embodiments, instead of setting the mounting shaft 220, connecting columns are directly set on the two side walls of the clearance groove 110 that are opposite to each other along the A direction, and the two ends of the rolling roller 210 are directly connected to the cigarette box push plate 100 through the two connecting columns respectively.
[0035] Preferably, the rolling friction assembly 200 further includes a mounting bearing (not shown in the figure), and the rolling roller 210 is mounted on the mounting shaft 220 via the mounting bearing. This arrangement improves the rolling sensitivity of the rolling roller 210 when it contacts the bottom surface of the cigarette box, further reducing the probability of the cigarette box pusher plate 100 causing indentations or damage to the bottom of the cigarette box. The mounting bearing can be adapted to deep groove ball bearings, needle rollers, angular contact ball bearings, cylindrical roller bearings, etc., according to actual needs; this embodiment does not impose a specific limitation.
[0036] In order to reduce the probability of damage to the bottom surface of the tobacco box caused by the rolling roller 210 when the rolling roller 210 is in rolling cooperation with the bottom surface of the tobacco box, in the embodiment, the rolling roller 210 is a nylon roller, and in other embodiments, the rolling roller 210 can also be a rubber roller.
[0037] Alternatively, the rolling roller 210 includes a rigid roller body and a flexible buffer shell, the rigid roller body is rotatably arranged on the mounting shaft 220 through a mounting bearing, and the flexible buffer shell covers the rigid roller body. The rigid roller body can improve the structural strength of the rolling roller 210 itself and the connection strength when connected to the mounting shaft 220; when the rolling roller 210 is in rolling cooperation with the bottom surface of the tobacco box, the flexible buffer shell contacts the bottom surface of the tobacco box, thereby reducing the probability of damage to the bottom surface of the tobacco box caused by the rolling roller 210. In the embodiment, the flexible buffer shell is made of rubber or nylon, and the material of the rigid roller body is not limited, which can be set according to the prior art.
[0038] In order to further reduce the connection difficulty of the mounting shaft 220 connected to the tobacco box push plate 100, and improve the connection strength and stability of the mounting shaft 220 connected to the tobacco box push plate 100, in the embodiment, the cross-sectional shape of both ends of the mounting shaft 220 is rectangular. The both ends of the mounting shaft 220 are provided with threaded holes, and the bolts (not shown in the figure) connect the mounting shaft 220 to the tobacco box push plate 100 through the corresponding threaded holes. When the rolling roller 210 needs to be replaced due to wear, the mounting shaft 220 can be removed by removing the bolts, thereby completing the replacement of the rolling roller 210, which is convenient and fast, and can improve the overall maintenance efficiency.
[0039] Preferably, the length of the avoidance groove 110 in the A direction is less than the length of the rolling roller 210. In this way, the rolling roller 210 can be moved in the A direction according to the size of the tobacco box being transported, so as to change the relative position of the rolling roller 210 and the tobacco box push plate 100, thereby improving the applicability of the push plate mechanism.
[0040] The number of rolling friction assemblies 200 arranged on the tobacco box push plate 100 can be adaptively set according to actual conditions, such as one group, two groups, three groups, four groups, etc. In the embodiment, two groups of rolling friction assemblies 200 are arranged on the tobacco box push plate 100, and the two groups of rolling friction assemblies 200 are arranged in the A direction. In this way, the contact area between the rolling roller 210 and the bottom surface of the tobacco box is increased, thereby further reducing the probability of causing indentation or damage to the bottom of the tobacco box by the tobacco box push plate 100.
[0041] In the embodiment, the size of the rolling roller 210, the tobacco box push plate 100, and the avoidance groove 110 is not limited, and can be adaptively set according to actual production needs.
[0042] Preferably, the cigarette box push plate 100 is provided with a plurality of countersunk holes 120 at intervals, and the connector passes through the corresponding countersunk holes 120 to connect to the cigarette box pushing and extending mechanism. In this embodiment, the connector is set as a threaded connector, which ensures the connection strength of the cigarette box push plate 100 while improving the connection convenience of the cigarette box push plate 100; at the same time, when the connector passes through the corresponding countersunk hole 120 to connect to the cigarette box pushing and extending mechanism, the thread head in the threaded connector is flush with the end face of the cigarette box push plate 100 near the cigarette box, avoiding the situation where the cigarette box surface abuts against the thread head due to the thread head protruding from the side of the cigarette box push plate 100 near the cigarette box, thus further ensuring the appearance quality of the cigarette box.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
