The horizontal rod 142a is connected between the two bent rods 142b, and is used to be connected with the output end of the electric cylinder 143 to drive the rotating frame 142 to move and drive the pressing roller 144 to move. In order to ensure that the pressing roller 144 applies force to the tobacco box evenly, the electric cylinder 143 is connected to the middle position of the horizontal rod 142a.

[0040] In some embodiments, the number of rotating frames 142 is at least two, and the two rotating frames 142 are symmetrically arranged on the fixed frame 141 to press or loosen the opposite sides of the tobacco box. In the embodiments of the present application, the rotating frame 142 and the pressing roller 144 are arranged on the two opposite sides of the tobacco box, which can act on the opposite sides of the tobacco box under the control of the control unit 130 according to the detection data of the level sensor 120, and is more conducive to the uniform distribution of tobacco leaves in the tobacco box.

[0042] The second aspect of the embodiment of the present application provides a tobacco leaf pressing device, which comprises a moving mechanism 200 and the tobacco leaf pressing balance assembly 100 described above. The moving mechanism 200 moves and places the tobacco leaf pressing balance assembly 100 on the tobacco leaves in the tobacco box or takes the tobacco leaf pressing balance assembly 100 out of the tobacco box.

[0043] In the embodiment of the present application, with reference to Figure 2 , the moving mechanism 200 can move the tobacco leaf pressing balance assembly 100 into the tobacco box. When the pressing reaches a balance, the tobacco leaf pressing balance assembly 100 can also be moved out of the tobacco box. The improvement of the tobacco leaf pressing device 10 of the embodiment of the present application is the same as the improvement of the tobacco leaf pressing balance assembly 100 described above. The technical problems that can be solved by the tobacco leaf pressing balance assembly 100 described above can also be solved by the tobacco leaf pressing device 10 of the embodiment of the present application, and thus the details are not described herein.

[0044] In some embodiments, the moving mechanism 200 comprises a frame body 210, a moving module 220 and a suction cup assembly 230. The moving module 220 is installed on the frame body 210, and the suction cup assembly 230 is installed on the moving module 220 so that the suction cup assembly 230 can suck the tobacco leaf pressing balance assembly 100 and place it in the tobacco box or take it out of the tobacco box.

[0045] In the embodiment of the present application, the moving module 220 can be configured to move the suction cup assembly 230 in the X-Y direction or in the X-Y-Z direction, and the details are not limited herein. The suction cup assembly 230 is used to suck the tobacco leaf pressing balance assembly 100 and place it in the tobacco box, or the suction cup assembly 230 takes it out of the tobacco box and transports it to the charging seat 300 for charging. The suction cup assembly 230 can also be replaced by other assemblies, but the method of clamping the pressing balance assembly is different. For example, the gripping assembly can use a gripper to clamp the pressing balance assembly, and the specific assembly can be a common mechanical hand assembly.

[0046] With reference to Figure 2 , the frame body 210 is a gantry frame, the moving module 220 comprises a first track fixed on the gantry frame and a second track horizontally moving on the first track, and the suction assembly is slidingly installed on the second track. Thus, the suction assembly can move in the X-Y direction. A track in the Z direction (i.e., the direction in which the tobacco box moves) can also be provided so that the suction assembly can also suck the tobacco leaf pressing balance assembly 100 at different positions.

[0047] In some embodiments, the tobacco leaf pressing device 10 further comprises a charging seat 300. The bottom end surface of the balance plate 110 is provided with a charging port 111. The moving mechanism 200 moves between the charging seat 300 and the tobacco box so that the tobacco leaf pressing balance assembly 100 is connected with the charging seat 300 or placed in the tobacco box. Figure 1The charging base 300 is located on one side of the cigarette box track, facilitating the transport of the suction component and the press-fit balancing component to the charging base 300 for charging. A charging port 111 is located at the bottom of the balancing plate 110. The charging port 111 is groove-shaped and can engage with a protrusion on the charging base 300 for charging. Magnetism can be provided at the charging port 111 to facilitate docking between the charging port 111 and the charging base 300.

[0048] Furthermore, there are multiple charging bases 300, and the moving mechanism moves among the multiple charging bases 300. That is, the moving mechanism can transport the press-fit balancing assembly that needs charging to the charging base 300 for charging, and simultaneously transport another press-fit balancing assembly that has already been charged to the cigarette box. In this embodiment, the moving mechanism is capable of moving in the XYZ directions, meaning that the same moving mechanism can move among multiple charging bases 300 to locate the charged press-fit balancing assembly and transport it to the cigarette box. In other embodiments, refer to... Figure 2 When the moving mechanism 200 can only move in the XY direction, each charging base 300 needs to be equipped with the same frame 210, moving module 220 and suction cup assembly 230 to cooperate with it, and move the cigarette box to the corresponding position of the charging base 300 so that the pressing and balancing assembly can be moved to the cigarette box or removed from the cigarette box.

[0049] Additionally, refer to Figure 2 The tobacco pressing device 10 also includes a conveying mechanism that transports the tobacco pressing balancing assembly 100 and the charging base 300 to one side of the tobacco box, thereby enabling the recycling of the pressing balancing assembly. The conveying mechanism includes a transport frame and a conveyor belt. The conveyor belt moves on the transport frame, and the charging base 300 is positioned on the conveyor belt and moves with it, transporting the charging base 300 to one side of the tobacco box. The conveyor belt is positioned on the transport frame and moves along the extension direction of the transport frame. When no charging base is provided, the pressing balancing assembly is placed directly on the conveyor belt; when the charging base 300 is provided, the charging base 300 is positioned on the conveyor belt, and the tobacco pressing balancing assembly 100 is placed above the charging base 300, cooperating with the charging base 300 for charging.

[0050] A third aspect of the present application provides a tobacco packaging device, including a loading device 20, a pre-compression device 30, a conveying mechanism 40 and the aforementioned tobacco pressing device 10, wherein tobacco boxes are placed on the conveying mechanism 40 and pass sequentially through the loading device 20, the pre-compression device 30 and the tobacco pressing device 10.

[0051] In the embodiments of this application, reference is made to Figure 2The loading device 20 is used for loading tobacco leaves into a tobacco box, and can load the tobacco leaves into the tobacco box by a feeder. The loading device 20 can also be provided with a conveying belt, and the tobacco box is conveyed to the conveying mechanism 40 by the conveying belt. The conveying mechanism 40 is used for moving the tobacco box between the loading device 20, the pre-pressing device 30 and the tobacco leaf pressing device 10. The conveying mechanism 40 can include a conveying track and a trolley, and the tobacco box is conveyed from the conveying belt of the loading device 20 to the trolley of the conveying track. After the tobacco leaves in the tobacco box are loaded, the tobacco leaves are prone to uneven distribution and to falling out of the tobacco box. The pre-pressing device 30 can pre-press the tobacco leaves in the tobacco box to preliminarily change the distribution of the tobacco leaves in the tobacco box. The pre-pressing device 30 can be a punch press. After the tobacco leaves in the tobacco box are pre-pressed by the pre-pressing device 30, the conveying mechanism 40 conveys the tobacco leaves to the tobacco leaf pressing device 10 for further balanced pressing.

[0052] The working principle of the tobacco leaf packaging equipment according to the embodiment of the present application is as follows:

[0053] The finished tobacco leaves are loaded into the tobacco box by the feeder, and then transported to the AGV transport vehicle by the belt conveyor and the roller conveyor. The AGV transport vehicle moves along the track laid on the ground, and when moving to the punch press station, the pressing plate of the punch press can compress the tobacco leaves in the tobacco box once, so as to minimize the gap between the tobacco leaves in the tobacco box.

[0054] The AGV transport vehicle continues to move along the track laid on the ground, and when moving to the pressing and balancing assembly station, the suction cup assembly 230 sucks the charged pressing and balancing assembly to the tobacco box on the AGV transport vehicle. The pressing and balancing assembly acts on the tobacco box, and is provided with a balancing plate 110, a horizontal sensor 120, a control unit 130, a fixed frame 141, a rotating frame 142, an electric cylinder 143 and a pressing roller 144. The balancing plate 110 is provided with a charging port 111, and the control unit 130 can control the electric cylinder 143 to drive the pressing roller 144 to move according to the signal transmitted by the horizontal sensor 120 on the balancing plate 110, so as to adjust the position of the balancing plate 110 in real time, so as to keep the tobacco leaves in the tobacco box from falling out and always uniformly distributed in the tobacco box during the transportation process of the AGV transport vehicle.

[0055] The AGV transport vehicle continues to move along the track laid on the ground, and when moving to the tobacco box packaging station, the suction cup assembly 230 sucks the pressing and balancing assembly on the tobacco box on the AGV transport vehicle to the charging seat 300 on the conveying belt. The charging port 111 on the pressing and balancing assembly can be matched and docked with the charging port 111 by the magnetic charging port 111 to assist the suction cup assembly 230.

[0056] The tobacco leaf packaging equipment of the embodiment of the application solves the problem of tobacco leaf scattering out of the tobacco box due to the large gap of tobacco leaves in the tobacco box, uneven distribution of tobacco leaves, large elasticity of tobacco leaves, and body shaking of the vehicle during transportation of the tobacco box; the pressing and assembling balance assembly automatically adjusts the distribution of tobacco leaves in the tobacco box, and has high automation; through the moving mechanism 200 and the charging base 300, automatic suction and charging of the tobacco leaf pressing and assembling balance assembly 100 are realized, so that the tobacco leaf pressing and assembling balance assembly 100 can be recycled, and the work efficiency is improved.

[0057] The above description of disclosed embodiments enables one of ordinary skill in the art to make or use the application. Various modifications to these embodiments will be readily apparent to those of ordinary skill in the art, and the generic principles defined herein can be applied to other embodiments without departing from the spirit or scope of the application.
