Description

Technical Field

[0001] The utility model relates to the field of medicine packaging machinery, in particular to a paper box discharging and transferring device of a blister cartoning machine. Background Art

[0002] The blister plate cartoning machine is a mechanical device for loading blister plates and instructions into cartons. The carton discharging and transferring device is an important part of the blister cartoning machine. Its function is to absorb the cartons in the carton material library and transfer the cartons to the box feeding device. During the feeding process, the flat carton is stretched into a three-dimensional carton. The box feeding device conveys the three-dimensional carton forward, and finally the blister plate and the instructions are pushed into the three-dimensional carton by the pushing device. The existing carton discharging and transferring device includes a support, a rotating power source, a central axis, a central fixed synchronous wheel, a revolution disk, and a plurality of suction nozzle rod assemblies. The suction nozzle rod assembly can realize both revolution and self-rotation, thereby sucking the carton down. At present, the suction rod of the suction nozzle rod assembly directly realizes self-rotation through the meshing of the planetary gear and the central fixed gear. However, the gap between the gears is large, and the suction nozzle of the suction nozzle rod assembly is easy to misalign with the carton when sucking the carton, resulting in the suction nozzle failing to suck the carton.

[0010] Figure 2 The structure of the utility model is shown in FIG. Figure 2 ;

[0011] Figure 3 It is a cross-sectional view of the utility model. DETAILED DESCRIPTION

[0012] like Figure 1 As shown, this carton discharging and transferring device is installed between the carton material store and the box feeding device. Its function is to transfer the folding cartons (or flat cartons) in the carton material store to the box feeding device below, and the box feeding device transports the cartons to the next station.

[0013] like Figure 1 As shown, the paper box discharging and transferring device includes a support 1, a rotating power source 8, a fixed shaft sleeve 6, a rotating disk 3 and a plurality of suction nozzle rod assemblies 2. Figure 2 As shown, the suction nozzle rod assembly 2 includes a suction nozzle 20, a suction rod 21 and a ventilation shaft 23. The suction nozzle 20 is connected to the suction rod 21, the suction rod 21 is connected to the ventilation shaft 23, and the ventilation shaft 23 is connected to the negative pressure source, so that the suction nozzle 20 can generate suction; the rotating disk 3 is connected to the connecting sleeve 5, the connecting sleeve 5 is connected to the transmission wheel 4, and the connecting sleeve 5 is rotatably mounted on the fixed shaft sleeve 6, the fixed shaft sleeve 6 is mounted on the support 1, and the transmission wheel 4 is transmission-connected to the rotating power source 8; the ventilation shaft 23 is rotatably mounted on the rotating disk 3, the ventilation shaft 23 is connected with a planetary synchronous wheel 24, the fixed shaft sleeve 6 is connected with a center synchronous wheel 7, and the planetary synchronous wheel 24 is transmission-connected to the center synchronous wheel 7 through a synchronous belt 70.

[0014] The working principle of this carton discharging and transferring device is as follows: Figure 1 and Figure 2As shown, the rotating power source 8 drives the transmission wheel 4 through the belt 41. Since the transmission wheel 4 is connected to the rotating disk 3 through the connecting sleeve 5, the transmission wheel 4 drives the rotating disk 3 to rotate. Since the suction nozzle rod assembly 2 is rotatably mounted on the rotating disk 3 through the ventilation shaft 23, the suction nozzle rod assembly 2 realizes revolution when the rotating disk 3 rotates; when the suction nozzle rod assembly 2 revolves, the planetary synchronous wheel 24 on the ventilation shaft 23 also realizes revolution. Since the planetary synchronous wheel 24 is connected to the center synchronous wheel 7 through the synchronous belt 70, and the center synchronous wheel 7 is fixed (fixedly mounted on the fixed shaft sleeve 6), the planetary synchronous wheel 24 realizes self-rotation when realizing revolution. Since the planetary synchronous wheel 24 is mounted on the ventilation shaft 23, the ventilation shaft 23 realizes automatic rotation, that is to say, the suction nozzle 20 of the suction nozzle rod assembly 2 realizes self-rotation. The self-rotation of the suction nozzle 20 is achieved through the transmission structure of the synchronous wheel and the synchronous belt, which can greatly improve the rotation accuracy of the suction nozzle 20, ensure that the suction nozzle 20 can always align with the paper box during suction, and improve the stability of paper box transfer.

[0015] In order to facilitate the connection between the ventilation shaft 23 and the suction rod 21, a suction rod fixing sleeve 22 is connected to the ventilation shaft 23, and the suction rod 21 is connected to the suction rod fixing sleeve 22. The ventilation shaft 23 and the suction rod 21 can be conveniently connected together through the suction rod fixing sleeve 22.

[0016] In order to ventilate the vent shaft 23, Figure 3 As shown, a ventilation shaft 60 is rotatably installed in the fixed sleeve 6, one end of the ventilation shaft 60 is connected to a cyclone connector 10 (cyclone connector 10 is a prior art), and the other end of the ventilation shaft 60 is connected to the rotating disk 3 through a connector 61, and the cyclone connector 10 is connected to a ventilation pipeline (the ventilation pipeline is a hose, not shown), the ventilation pipeline is located in the ventilation shaft 60, and the ventilation pipeline is connected to the ventilation shaft 23 through a rotary joint 25. Since the ventilation shaft 60 is connected to the rotating disk 3 through the connector 61, when the rotating disk 3 rotates, the ventilation shaft 60 also rotates at the same time, that is, the ventilation shaft 23 keeps rotating synchronously with the rotating disk 3, so that the ventilation pipeline in the ventilation shaft 23 also keeps rotating synchronously with the suction nozzle rod assembly 2 on the rotating disk 3, and the problem of ventilation pipeline winding will not occur. At the same time, since the rotary joint 25 has a self-spinning function, when the ventilation shaft 60 rotates, it will not cause the ventilation pipeline to be wound.

[0017] The heights of boxes of different specifications are different. In order to adapt to the transportation of boxes of different specifications, the support 1 is installed on the base 9 in a lifting and adjusting manner. Specifically, a slider is connected to the support 1, and a guide rail 90 is connected to the base 9. The slider is slidably arranged on the guide rail 90. A rotatable adjustment screw 11 is installed on the base 9, and the adjustment screw 11 is threadedly connected with the screw sleeve on the support 1. During adjustment, by rotating the adjustment screw 11, the support 1 can be adjusted up and down on the guide rail 90, so that the entire device can be moved up and down, thereby meeting the transportation of boxes of different specifications. Of course, the lifting and lowering adjustment of the support 1 can be adjusted manually or by a motor.
