An empty box conveying drive assembly and a full box conveying drive assembly are respectively provided on the empty box conveying channel and the full box conveying channel. The side of the empty box conveying channel at the box outlet is connected to the side of the full box conveying channel at the box inlet. An empty box pushing assembly is provided between the box outlet end of the empty box conveying channel and the box inlet end of the full box conveying channel.

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 5 As shown, a lighter clamping claw assembly provided in this embodiment includes an air claw seat 1, two hinge through holes 2 are arranged at intervals below the air claw seat 1, a hinge pin 3 is rotatably connected in each hinge through hole 2, a pneumatic clamping seat 4 is arranged on the hinge pin 3, the center of the pneumatic clamping seat 4 passes through the hinge pin 3, and a pneumatic connecting head 5 is arranged on the side above the pneumatic clamping seat 4, two pneumatic clamping seats 4 are arranged opposite to each other on the left and right, and two arc grooves 6 are arranged on the inner side below each pneumatic clamping seat 4, a longitudinally arranged clamping rod 7 is fixed in each arc groove 6, and the four clamping rods 7 are respectively located at the surrounding positions of the outer side of the lighter 8 and are used to clamp the lighter 8, a spring 9 is arranged between the two pneumatic clamping seats 4, the spring 9 is installed in the air claw seat 1, and the two ends of the spring 9 are respectively connected to the corresponding pneumatic clamping seat 4, and the hinge pin 3 is a stainless steel knurled locating pin.

[0022] The specific working principle of this structure is as follows:

[0023] The device is installed to the corresponding position of the lighter processing equipment, and then the vent hole of the air claw seat 1 is connected to the pneumatic device. When working, the air claw seat 1 pushes the two pneumatic clamping seats 4 outward after ventilation, and because the centers of the two pneumatic clamping seats 4 are hinged on the air claw seat 1, it is ensured that the two sides of the bottom of the two pneumatic clamping seats 4 move inward, and finally the clamping openings of the two pneumatic clamping seats 4 become smaller, so that the four clamping rods 7 clamp the lighter 8 to achieve the clamping operation of the lighter 8. Conversely, the lighter 8 is released. At this time, since two clamping rods 7 are provided on each pneumatic clamping seat 4, when clamping the lighter 8, the four clamping rods 7 are evenly located around the lighter 8 to achieve a four-point clamping effect on the lighter 8, ensuring that the clamping product is more accurate, more stable and more efficient. The addition of the four-rod clamping rods 7 makes the force points more uniform, and there will be no position offset during the clamping process, which affects the clamping effect and the problem of inaccurate clamping.

[0024] Preferably, for the convenience of operation, a pneumatic input main joint 10 is provided in the air claw seat 1, and a three-way T-shaped connector 11 is connected to the lower part of the pneumatic input main joint 10, and the common end of the three-way T-shaped connector 11 is connected to one end of the pneumatic input main joint 10, and the other two ends of the three-way T-shaped connector 11 are respectively connected to a corresponding pneumatic connector 5. At the same time, in order to improve the sealing performance, the pneumatic connector 5 is sleeved in the three-way T-shaped connector 11, and a sealing ring 12 is provided on the outer side of the pneumatic connector 5. The outer wall of the sealing ring 12 is against the inner wall of the three-way T-shaped connector 11 to achieve sealing. In this embodiment, the pneumatic connector 5 is sleeved in the three-way T-shaped connector 11, and the sealing ring 12 is provided on the outer side of the pneumatic connector 5. A sealing ring 12 is set on the outside of the joint 5, and the pneumatic connector 5 is inserted into the three-way T-shaped connector 11. When working, the other end of the pneumatic input main connector 10 is connected to the gas generator. At this time, the pneumatic input main connector 10 is ventilated to ensure that the three-way T-shaped connector 11 is ventilated and then pushes the upper ends of the pneumatic clamping seats 4 on both sides below to push outward. Since the midpoint of the pneumatic clamping seat 4 is hinged on the air claw seat 1, it is finally guaranteed that the lower part of the pneumatic clamping seat 4 moves inward, and finally the clamping openings of the two pneumatic clamping seats 4 become smaller, so that the four clamping rods 7 clamp the lighter 8 to realize the clamping operation of the lighter 8, otherwise, the lighter 8 is released; therefore, the sealing performance is improved by adding a sealing ring 12 to avoid air leakage affecting the clamping effect.

[0025] Preferably, in order to avoid damaging the surface of the lighter 8 when clamping the lighter 8 and to increase the scrap rate, the bottom of each clamping rod 7 is a tapered portion 701, and the bottom of the tapered portion 701 is an arc surface 702. In the above structure, the bottom of the clamping rod 7 is set as the tapered portion 701, and the bottom of the tapered portion 701 is set as the arc surface 702, to ensure that when the clamping rod 7 is inserted into the lighter 8 as the clamping drive device moves downward, the surface of the lighter 8 is not damaged, thereby affecting the scrap rate of the lighter 8; and the clamping drive device that needs to be explained belongs to the conventional technology in this field, so it is not described in detail; at the same time, in this embodiment, for easy installation, each clamping rod 7 is fixed to the corresponding one by a positioning pin 703 In the arc groove 6, in this embodiment, the clamping rod 7 is installed and locked to the arc groove 6 by the positioning pin 703 to facilitate later disassembly. If the clamping rod 7 is worn, the clamping rod 7 can be replaced later. At the same time, in order to increase the friction force in the later stage, a silicone layer can be set on the surface of the clamping rod 7 to increase the friction with the surface of the lighter 8, thereby improving the clamping effect on the lighter 8. In this embodiment, as a preference, in order to facilitate the later installation of the device, two screw mounting holes 13 are set above the air claw seat 1, and the screw mounting holes 13 are set on the air claw seat 1. The device can be conveniently installed on the corresponding air claw workbench with the screws. Different numbers of the devices can be set according to the number of clamping in the later stage.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
