[0036] Specifically, the primary frame 210 includes a primary frame side panel, a primary frame top panel and a primary frame cross panel, and the two primary frame side panels are arranged opposite to each other; the two primary frame cross panels are fixed to the two ends of the bottom of the primary frame side panels; the primary frame top panel is fixed to the top of the two primary frame side panels; a box structure is formed by the two primary frame side panels, the primary frame top panel and the two primary frame cross panels to improve the stability of the primary frame 210.

[0041] Specifically, the secondary frame 310 includes a secondary frame side plate, a secondary frame top plate and a secondary frame support plate, and the two secondary frames are arranged opposite to each other; the two secondary frame support plates are fixed between the secondary frame side plates, and the two ends are respectively abutted against the secondary frame side plates; the secondary frame top plate is fixed to the top of the two secondary frame side plates.

[0042] The secondary sliding assembly 320 includes a secondary slider and a secondary sliding rail, wherein the secondary sliding rail is fixed to the inner side of the primary frame side panel, the secondary slider is arranged along the length direction of the primary frame side panel, and the secondary slider is fixed to the outer side of the secondary frame side panel. The secondary slider is slidably connected to the secondary sliding rail to achieve a sliding connection between the secondary frame 310 and the primary frame 210. In this embodiment, both sides of the secondary frame 310 are slidably connected to the primary frame 210 through the secondary sliding assembly 320. Two secondary sliders are arranged on the secondary sliding rail of this embodiment, thereby further improving the stability of the relative movement between the secondary frame 310 and the primary frame 210.

[0043] The linkage assembly 330 includes an input clamping plate 331, an output clamping plate 332, a first synchronous pulley 333, a second synchronous pulley 334 and a synchronous toothed belt 335. The first synchronous pulley 333 and the second synchronous pulley 334 are respectively arranged at two ends of the bottom of the primary frame 210, the first synchronous pulley 333 is fixed to the primary frame horizontal plate close to the push plate assembly 400 through a synchronous pulley seat, and the second synchronous pulley 334 is fixed to the primary frame horizontal plate away from the push plate assembly 400 through a synchronous pulley seat; the synchronous toothed belt 335 is sleeved on the first synchronous pulley 333 and the second synchronous pulley 334 in the circumferential direction. Define the direction from the first synchronous pulley 333 to the second synchronous pulley 334 as the first direction, and the direction from the second synchronous pulley 334 to the first synchronous pulley 333 as the first direction, then the synchronous toothed belt 335 on both sides of the first synchronous pulley 333 and the second synchronous pulley 334 respectively form a first direction segment and a second direction segment, the first direction segment is the synchronous toothed belt 335 in the direction from the first synchronous pulley 333 to the second synchronous pulley 334, and the second direction segment is the synchronous toothed belt 335 in the direction from the second synchronous pulley 334 to the first synchronous pulley 333;

[0044] The input clamping plate 331 is clamped and fixed in the first direction section, and the input clamping plate 331 is arranged near the first synchronous pulley 333; the bottom of the input clamping plate 331 is connected to the horizontal plate of the fixed frame 100 near one end of the push plate assembly 400 at the bottom through the clamping plate seat. The output clamping plate 332 is clamped and fixed in the second direction section, and the output clamping plate 332 is arranged near the second synchronous pulley 334, and the side of the output clamping plate 332 is connected to the inner side of the secondary frame side plate; thereby, the relative displacement between the primary frame 210 and the fixed frame 100 provides power, driving the secondary frame 310 to move back and forth along the length direction of the primary frame 210.

[0045] The push plate assembly 400 of this embodiment includes a box push plate 410, the side of which is connected to the end of the secondary frame 310; the box push plate 410 has a pushing surface adapted to the inner cavity of the carton, and the box push plate 410 pushes the hard box out of the carton under the drive of the secondary frame 310.

[0046] When in use, the servo motor 231 provides power, and drives the lead screw 241 to rotate through the driving wheel 232, the power wheel 233 and the transmission belt 234. The rotation drives the lead screw to rotate forward and reverse, thereby driving the first-level frame 210 to move back and forth relative to the fixed frame 100, thereby realizing the telescopic function of the first-level pushing component 200. When the first-stage pushing assembly 200 is extended relative to the fixed frame 100, the synchronous pulley group fixed on the first-stage frame 210 and the input clamping plate 331 fixed on the fixed frame 100 generate relative movement, so that the input clamping plate 331 moves in the first direction (that is, the direction in which the first synchronous pulley 333 points to the second synchronous pulley 334), and the first synchronous pulley 333 and the second synchronous pulley 334 rotate under the drive of the synchronous toothed belt 335, driving the output clamping plate 332 to move in the second direction (that is, the direction in which the second synchronous pulley 334 points to the first synchronous pulley 333), driving the side plate of the secondary frame fixed to the output clamping plate 332 to move, and driving the secondary frame 310 to move in the second direction relative to the first-stage frame 210, that is, the secondary frame 310 extends from the first-stage frame 210, thereby realizing the telescopic function of the second-stage pushing assembly 300. To sum up, the servo motor 231 directly drives the first-level pushing assembly 200 to move, and through the movement of the first-level pushing assembly 200, it drives the synchronous toothed belt 335 to rotate, and then drives the secondary frame 310 to move linearly along the secondary slide rail, so as to achieve the function of synchronous extension and retraction of the secondary pushing assembly 300 and the first-level pushing assembly 200, and drives the strip box push plate 410 fixed at the end of the secondary frame 310 to push the hard strip box out of the carton. The box pushing device of the automatic cigarette carton opener of this embodiment adopts a multi-stage pushing assembly synchronous extension and retraction method, which makes the box pushing process smoother and the structure more compact under the condition of the same box pushing stroke, which is beneficial to the optimization of the internal space of the automatic cigarette carton opener.
