Description

Technical Field

[0001] This utility model relates to the field of cigarette pack processing technology, and in particular to a cigarette pack pushing mechanism and a cigarette pack packaging machine. Background Technology

[0002] The double push rods of the packaging machine function to push cigarette packs during normal operation. It consists of a front push rod and a rear push rod, both mounted on the same drive shaft. An octagonal conveyor turret connects the front and rear push rods. The reciprocating motion of the drive shaft drives the front and rear push rods to move back and forth, pushing the cigarette packs. The rear push rod pushes the double packs of cigarettes lifted by the elevator into the soldering iron sealing channel for hot sealing the ends of the packs. During this pushing process, the last two packs push the first two packs into the octagonal conveyor turret. During the intermittent rotation of the octagonal conveyor turret, defective packs are removed. When the empty mold box rotates to the next station, a replenisher adds two qualified packs. The octagonal conveyor turret continues to rotate intermittently, pausing briefly at the entrance of the carton packaging machine. During this pause, the front push rod pushes the double packs of cigarettes into the packaging station of the carton packaging machine.

[0003] Occasionally, due to unforeseen circumstances, defective cigarette packs may appear during normal operation. These packs are removed at the rejection station of the octagonal conveyor turret and fall into the waste bin under their own weight. However, sometimes severely deformed or loose packs fail to fall on time due to gravity, and the octagonal turret begins to rotate. This causes the defective packs to flow to the next process. When the octagonal turret reaches the carton packaging machine inlet, the front push rod pushes the packs into the machine. Because defective packs are not completely removed, blockages can occur on the front push rod. When the resistance is too high, the front push rod can become misaligned relative to the drive shaft, potentially damaging the equipment. In this case, the equipment cannot operate normally and maintenance personnel need to readjust and reset the phase of the double push rod, resulting in low production efficiency.

[0004] Therefore, there is an urgent need for a cigarette pack pushing mechanism and a cigarette pack packaging machine to solve the aforementioned problems. Utility Model Content

[0005] Based on the above, the purpose of this utility model is to provide a cigarette pack pushing mechanism and a cigarette pack packaging machine.

The driving member is motive-connected to the driving shaft and is used to drive the driving shaft to reciprocate along the first direction. The cigarette pack pushing mechanism further includes:

[0008] A connector, the top of which is connected to the drive shaft;

[0009] A pusher rod, one end of which is hinged to the connector, and when the pusher rod rotates relative to the connector to the pusher position, the other end of the pusher rod is used to push the cigarette pack;

[0010] A damping assembly is provided, wherein when the pusher rod is located at the pusher station, the damping assembly is located between the pusher rod and the connector, and the damping assembly is used to apply a damping force between the pusher rod and the connector.

[0011] As a preferred technical solution for a cigarette pack pushing mechanism, the bottom end of the connector is provided with a hinge groove, the inner wall of the hinge groove is provided with a hinge shaft extending along a second direction, the second direction being perpendicular to the first direction, the hinge groove is provided with a clearance opening along the first direction and on the side away from the cigarette pack, and the end of the pusher rod extends into the hinge groove and is hinged to the hinge shaft.

[0012] As a preferred technical solution for a cigarette pack pushing mechanism, the damping component includes an elastic pressure plate and a spherical component. A sliding hole is provided on one side of the hinge groove, and a groove is provided on the side of the pushing rod near the sliding hole. The spherical component is slidably connected to the sliding hole, and one side of the spherical component is embedded in the groove. The first end of the elastic pressure plate is connected to the outer wall of the connector, and the second end of the elastic pressure plate is pressed against the other side of the spherical component.

[0013] As a preferred technical solution for a cigarette pack pushing mechanism, the damping component further includes a fastening screw, the first end of the elastic pressure plate is provided with a first through hole, the outer wall of the connector is provided with a first threaded hole, and the fastening screw passes through the first through hole and is threadedly connected to the first threaded hole.

[0021] This utility model provides a cigarette pack pushing mechanism and a cigarette pack packaging machine. The connecting part and the pushing rod are set as separate structures. During operation, the pushing rod rotates relative to the connecting part to the pushing position. When the driving part drives the driving shaft to reciprocate, it drives the pushing rod to move along the first direction. The pushing rod can push the cigarette pack. When a deformed or severely loose cigarette pack moves in front of the pushing rod, the resistance in front of the pushing rod is greater than the damping force provided by the damping component. The pushing rod then overcomes the damping force and rotates relative to the connecting part. The pushing rod can automatically disengage when the force is too large, protecting the cigarette pack pushing mechanism from misalignment due to excessive force and preventing overload damage to the equipment, thus improving the service life of the equipment. Afterwards, the operator only needs to remove the defective cigarette packs and operate the pushing rod to reset and rotate to the pushing position. The operation is simple and improves production efficiency. Attached Figure Description

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0031] like Figure 1As shown, this embodiment provides a cigarette packaging machine, which includes a cigarette pack pushing mechanism. The cigarette pack pushing mechanism includes a driving component, a connecting member 2, a pushing rod 4, and a damping component 5. Specifically, the driving component includes a driving member and a driving shaft 1 extending along a first direction. The driving member is driven and connected to the driving shaft 1 and is used to drive the driving shaft 1 to reciprocate along the first direction. The top end of the connecting member 2 is connected to the driving shaft 1. One end of the pushing rod 4 is hinged to the connecting member 2. When the pushing rod 4 rotates relative to the connecting member 2 to the pushing position, the other end of the pushing rod 4 is used to push the cigarette pack. When the pushing rod 4 is at the pushing position, the damping component 5 is located between the pushing rod 4 and the connecting member 2 and is used to apply a damping force between the pushing rod 4 and the connecting member 2.

[0032] In this embodiment, the connector 2 and the pusher rod 4 are configured as separate structures. During operation, the pusher rod 4 rotates relative to the connector 2 to the pusher position. When the drive shaft 1 reciprocates, the pusher rod 4 moves along the first direction. The pusher rod 4 can push the cigarette packs. When a severely deformed or loose cigarette pack moves to the front of the pusher rod 4, the resistance in front of the pusher rod 4 exceeds the damping force provided by the damping component 5. The pusher rod 4 then overcomes the damping force and rotates relative to the connector 2. The pusher rod 4 can automatically disengage when subjected to excessive force, protecting the cigarette pack pushing mechanism from misalignment due to excessive force and preventing overload damage to the equipment, thus improving the equipment's service life. Subsequently, the operator only needs to remove the defective cigarette packs and operate the pusher rod 4 to reset and rotate to the pusher position. The operation is simple and improves production efficiency.

[0033] In this embodiment, the driving component can be a motor-linkage drive or a motor drive, which are existing technologies and will not be described in detail here.

[0034] like Figure 1 and Figure 2 As shown, in this embodiment, the bottom end of the connector 2 is provided with a hinge groove 21, and the inner wall of the hinge groove 21 is provided with a hinge shaft 3 extending along a second direction, which is perpendicular to the first direction. The hinge groove 21 has a clearance opening 26 on the side along the first direction away from the cigarette pack. The end of the pusher rod 4 extends into the hinge groove 21 and is hinged to the hinge shaft 3. When the resistance experienced by the pusher rod 4 is greater than the damping force provided by the damping component 5, the pusher rod 4 rotates around the hinge shaft 3 and exits through the clearance opening 26. In this embodiment, the first direction is X, and the second direction is Y.

[0035] In this embodiment, the damping component 5 includes an elastic pressure plate 51 and a spherical component 52. A sliding hole 22 is provided on one side of the hinge groove 21, and a groove is provided on the side of the pusher rod 4 near the sliding hole 22. The spherical component 52 is slidably connected to the sliding hole 22, and one side of the spherical component 52 is embedded in the groove. The first end of the elastic pressure plate 51 is connected to the outer wall of the connector 2, and the second end of the elastic pressure plate 51 is pressed against the other side of the spherical component 52. When the pusher rod 4 is located at the pusher position, one side of the spherical component 52 is embedded in the groove of the pusher rod 4, providing damping force for the pusher rod 4. This damping force prevents the pusher rod 4 from rotating relative to the connector 2. When the resistance in front of the pusher rod 4 is greater than the damping force provided by the damping component 5, the pusher rod 4 drives the spherical component 52 to move away from the pusher rod 4. The spherical component 52 pushes against the second end of the elastic pressure plate 51 and deforms, forming overload protection.

[0036] In this embodiment, the damping component 5 also includes a fastening screw 53. The first end of the elastic pressure plate 51 is provided with a first through hole 511, and the outer wall of the connector 2 is provided with a first threaded hole 25. The fastening screw 53 passes through the first through hole 511 and is threaded to the first threaded hole 25, thereby realizing that the first end of the elastic pressure plate 51 is connected to the outer wall of the connector 2.

[0037] Preferably, there are two of each of the first through hole 511, the first threaded hole 25, and the fastening screw 53, and they correspond one-to-one. The first end of the elastic pressure plate 51 is connected to the outer wall of the connector 2 by two fastening screws 53. On the one hand, this improves the connection strength; on the other hand, it prevents the elastic pressure plate 51 from rotating relative to the outer wall of the connector 2, thereby improving reliability.

[0038] More preferably, the damping assembly 5 further includes a pressure plate 54, which has a second through hole 541. The pressure plate 54 is pressed against the first end of the elastic pressure plate 51. A fastening screw 53 is sequentially inserted through the second through hole 541 and the first through hole 511 and threaded into the first threaded hole 25. The pressure plate 54 presses the first end of the elastic pressure plate 51 against the outer wall of the connector 2, increasing the contact area with the elastic pressure plate 51 and improving the connection stability.

[0039] In other embodiments, the damping assembly 5 includes a first magnetic element and a second magnetic element. The first magnetic element is located on the side of the hinge groove 21 along a first direction and close to the cigarette pack, and the second magnetic element is located on the side of the pusher rod 4 close to the first magnetic element. The first magnetic element is magnetically connected to the second magnetic element. When the pusher rod 4 is in the pusher position, the magnetic attraction of the first and second magnetic elements forms a damping force between the pusher rod 4 and the connector 2, thus providing overload protection. The first and second magnetic elements can be magnets.

[0040] Preferably, the cigarette pack pushing mechanism further includes a detection sensor 6, which is used to detect the position of the push rod 4 relative to the connecting member 2. In this embodiment, the position of the drive shaft 1 can be identified by the equipment encoder. When the drive shaft 1 drives the push rod 4 to push the cigarette pack, the detection sensor 6 performs detection, which can detect whether the push rod 4 is located at the pushing position. When the resistance is too high, the push rod 4 can automatically disengage, and the detection sensor 6 detects that the push rod 4 is not at the pushing position and stops the machine, reminding the operator to perform maintenance. After the operator has dealt with the equipment blockage fault, the push rod 4 can be manually reset, saving a lot of maintenance time. In this embodiment, the detection sensor 6 can be a proximity sensor, which is located on one side of the second end of the push rod 4 along the second direction. When the push rod 4 pushes the cigarette pack, the proximity sensor detects whether the push rod 4 is located at the pushing position. In other embodiments, the detection sensor 6 can be a photoelectric sensor, which can detect the position of the end of the push rod 4 used to push the cigarette pack.

[0041] In this embodiment, the top end of the connector 2 is provided with a connecting groove 23, and the connecting groove 23 is provided with an opening 24. One of the two sidewalls opposite to the opening 24 is provided with a third through hole, and the other is provided with a second threaded hole. The connecting groove 23 is sleeved on the drive shaft 1, and a screw passes through the third through hole and is threaded into the second threaded hole, thereby connecting the connector 2 to the drive shaft 1. Preferably, the inner wall of the connecting groove 23 is provided with a keyway 27, and a key is installed on the outer wall of the drive shaft 1. The key is embedded in the keyway 27, which can prevent the connector 2 from rotating relative to the drive shaft 1.

[0042] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
