Description

Technical Field

[0001] The utility model relates to the technical field of cigarette packet packaging, in particular to a limiting ejector rod device for a cigarette packet packaging machine and a cigarette packet packaging machine. Background Art

[0002] The YF64 cigarette packet storage device is an important part of the ZB418 cigarette packet packaging machine. It is mainly a temporary storage device for cigarette packets that connects the upstream (small box) cigarette packet packaging machine and the downstream transparent paper packaging machine. Its function is that when the downstream transparent paper packaging machine stops, the upstream cigarette packet packaging machine is still running. At this time, the cigarette packets continuously output by the upstream cigarette packet packaging machine will be intercepted when passing through the YF64 cigarette packet storage device, and then pushed into the storage box of the cigarette packet storage device. When the downstream transparent paper packaging machine resumes operation, the cigarette packets in the storage box will output the cigarette packets orderly according to the number of cigarette packets in the conveying channel and provide them for the transparent paper packaging machine to use.

[0003] Specifically as Figure 1 shown, the conveying line of the cigarette packet packaging machine includes a lower conveying frame 100 and an upper conveying frame 200. Conveyor belts are provided on both the lower conveying frame 100 and the upper conveying frame 200. When the downstream transparent paper packaging machine breaks down, the cigarette packets conveyed from the upstream cigarette packet packaging machine are stopped at a set position on the lower conveying frame 100 corresponding to the inlet of the storage box. When the number of cigarette packets meets the pushing quantity, the air cylinder 300 starts, and the top plate 400 located below the lower conveying frame 100 and the upper conveying frame 100 are pushed upward. The purpose is to separate the cigarette packets from the conveyor belt, release the conveying force of the upper and lower conveyor belts on the cigarette packets, and push the cigarette packets up to the same level as the inlet of the storage box through the top plate 400, and then push the multiple groups of cigarette packets into the storage box through a push rod. When the push rod pushes the cigarette packets, in order to prevent the end of the multiple groups of cigarette packets, that is, the last cigarette packet, from tipping over, a cigarette packet ejector rod device 500 is provided at the corresponding position of the cigarette packet packaging machine. The cigarette packet ejector rod device 500 is used to contact the top surface of the end cigarette packet to limit the cigarette packet to prevent it from tipping over. However, since the current cigarette packet ejector rod device is in hard contact with the cigarette packet, it may squeeze the cigarette packet and deform it or cause a jamming situation when limiting the cigarette packet. In addition, when the cigarette packet ejector rod device is adjusted up and down according to the size of the cigarette packet, the adjustment accuracy is not high and the adjustment difficulty is large, resulting in poor use effects.

Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0051] Please refer to Figures 1 to 5 . It should be noted that the illustrations provided in this embodiment only schematically illustrate the basic concept of the present utility model. Therefore, only the components related to the present utility model are shown in the drawings, rather than being drawn according to the number, shape, and size of the components in actual implementation. The types, quantities, and proportions of the components in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0052] One aspect of the present utility model provides a limiting ejector rod device for a cigarette pack packaging machine. The limiting ejector rod device is used to limit the cigarette pack, specifically as Figure 2 shown. The limiting ejector rod device includes an adjustable ejector rod 10, a fixed block 11, an adjusting screw 12, and an adjusting block 13. Among them, a flexible limiting member 101 is provided at the bottom of the adjustable ejector rod 10. The top of the adjustable ejector rod 10 is fixedly connected to the fixed block 11 through a locking member. The fixed block 11 is used to be connected to the frame of the cigarette pack packaging machine, so as to fix the limiting ejector rod device on the frame of the cigarette pack packaging machine. The adjusting screw 12 is rotatably arranged on the fixed block 11, and the fixed block 11 can limit the adjusting screw 12 to move along its axial direction. The adjusting screw 12 is threadedly connected to the adjusting block 13, and the adjusting block 13 is connected to the adjustable ejector rod 10.

[0053] The beneficial effects of the limit ejector rod device for the cigarette pack packaging machine of the present utility model are as follows. When the limit ejector rod device of the present utility model limits the end cigarette pack, since the bottom of the adjustable ejector rod 10 is provided with a flexible limit member, the flexible limit member makes soft contact, that is, elastic contact, with the cigarette pack, so that it can avoid squeezing the cigarette pack or causing the phenomenon of cigarette pack jamming. At the same time, when adjusting the height of the flexible limit member 101 according to cigarette packs of different specifications and sizes, first loosen the locking member 20 that fixes the adjustable ejector rod 10, so that the adjustable ejector rod 10 can move up and down. Then, by screwing the adjusting screw 12 to rotate, the adjusting block 13 will move up and down along the axial direction of the adjusting screw 12. Furthermore, the adjusting block 13 drives the adjustable ejector rod 10 to move up and down together, thereby realizing the adjustment of the height of the flexible limit member 101. The operation is convenient and the adjustment accuracy is high.

[0054] Preferably, as Figure 2 shown, in this embodiment, the flexible limit member 101 includes a connecting plate 1011 and a brush 1012. Among them, the connecting plate 1011 is connected to the bottom of the adjustable ejector rod 10, and the brush 1012 is connected to the connecting plate 1011. When limiting the cigarette pack, the top of the cigarette pack is contacted by the brush 1012 to prevent it from tipping over. As a preference, in this embodiment, the material of the brush 1012 is nylon, that is, the brush 1012 is made of nylon filaments, so as to improve the wear resistance of the brush.

[0055] Furthermore, in order to improve the stability of the flexible limit member 101 in limiting the cigarette pack, as Figure 2 shown, in this embodiment, the brush 1012 has a set inclination angle with the vertical direction, and the inclination direction of the brush 1012 is the same as the conveying direction of the cigarette pack. Through this structural design, when pushing the cigarette pack into the storage box, the brush 1012 can conform to the movement of the cigarette pack, thereby improving the stability of the push. As a preference, in this embodiment, the set inclination angle between the brush 1012 and the vertical direction is 10°. Of course, in other alternative embodiments, those skilled in the art can set the inclination angle between the brush and the vertical direction to be less than 10° or greater than 10° according to requirements.

[0056] Furthermore, as Figures 2 to 3As shown, the locking member includes a clamping hole 21 provided on the fixed block 11. The top of the adjustable ejector rod 10 is inserted into the clamping hole 21. Specifically, an opening slot 211 is provided on one side of the clamping hole 21. The opening slot 211 divides the fixed block 11 into a first clamping block 111 and a second clamping block 112. Connecting holes 1110 are provided on both the first clamping block 111 and the second clamping block 112. A locking bolt (not shown in the figure) is inserted through the connecting hole on the first clamping block 111 and the connecting hole on the second clamping block 112. By tightening the locking bolt, the first clamping block 111 and the second clamping block 112 can be made to approach each other, so that the clamping hole 21 can clamp the adjustable ejector rod 10. When it is necessary to adjust the height of the adjustable ejector rod 10, the locking screw can be loosened. Specifically, a fixing hole 110 is also provided on the fixed block 11. The fixed block 11 is connected to the frame of the cigarette pack packaging machine by inserting a fixing bolt through the fixing hole 110.

[0057] Further, as Figure 3 and Figure 4 shown, a first limiting flange 121 and a second limiting flange 122 are provided on the adjusting screw 12. The first limiting flange 121 and the second limiting flange 122 are arranged at intervals up and down. Correspondingly, a clamping groove 113 is provided on the fixed block 11. The bottom surface of the first limiting flange 121 is in contact with the top wall of the clamping groove 113, and the top surface of the second limiting flange 122 is in contact with the bottom wall of the clamping groove 113. Through this structural design, that is, the adjusting screw 12 is clamped in the clamping groove 113 through the part between the first limiting flange 121 and the second limiting flange 122, thereby restricting the adjusting screw 12 from moving up and down. Therefore, when the adjusting screw 12 is rotated, since the adjusting screw 12 cannot move up and down, the adjusting block 13 threadedly connected to the adjusting screw 12 will move up and down along the axial direction of the adjusting screw 12. Since the adjusting block 13 is connected to the adjustable ejector rod 10, the adjusting block 13 drives the adjustable ejector rod 10 to move up and down together. Specifically, as Figure 2 shown, in this embodiment, the adjusting block 13 is connected to the adjustable ejector rod 10 through a connecting screw 131, with a simple structure and convenient disassembly and assembly.

[0058] Further, when adjusting the up and down movement of the adjusting block 13, in order to improve the stability of the up and down movement of the adjusting block 13, preferably, as Figure 2 and Figure 5 shown, in this embodiment, a guiding block 14 is also fixedly provided on one side of the fixed block 11. A sliding groove 141 is provided on the guiding block 14. The sliding groove 141 extends in the vertical direction. Correspondingly, a sliding block 130 is provided on the adjusting block 13, which is slidably embedded in the sliding groove 141.

[0059] Further, in this embodiment, the adjusting screw 12 uses an M5 thread with a major diameter of 5 mm, and the pitch of the thread on the adjusting screw 12 is 0.8 mm. By rotating the adjusting screw 12 one full turn, i.e., 360°, the adjusting block 13 can be moved up and down by 0.8 mm, and rotating 45° can achieve a movement of the adjusting block 13 by 0.1 mm. It can be seen that the adjustment accuracy is high and the operation is convenient.

[0060] On the other hand, the present utility model also provides a cigarette pack packaging machine, which includes the above-described limiting ejector rod device.

[0061] The beneficial effects of this cigarette pack packaging machine are the same as those of the above-described limiting ejector rod device, so they will not be elaborated here.

[0062] In summary, the limiting ejector rod device for a cigarette pack packaging machine and the cigarette pack packaging machine of the present utility model can avoid squeezing the cigarette pack or causing the cigarette pack to jam. At the same time, a high adjustment accuracy can be achieved for the adjustable ejector rod, and the adjustment operation is simple and convenient. Therefore, the present utility model effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

[0063] The above embodiments are only illustrative of the principles and effects of the present utility model, and are not used to limit the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present utility model should still be covered by the claims of the present utility model.
