Description

Technical Field

[0001] This utility model relates to the field of cigarette pack processing technology, and in particular to a cigarette pack pushing magnetic overload protection device 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 be generated during normal operation. These packs should fall into the waste bin by their own weight at the rejection station of the octagonal conveyor turret. However, when the packs are deformed or severely loose, and their weight is insufficient to make them fall on time, the octagonal turret continues to rotate, and the defective packs flow into the next process. At the carton packaging machine inlet, the push rod pushes the packs, but blockages occur because defective packs are not completely removed. Excessive resistance can cause the push rod to misalign with the drive shaft, potentially damaging the equipment and causing it to stop operating. Maintenance personnel must then readjust and reset the double push rod phase, impacting production efficiency.

[0004] Therefore, there is an urgent need for a cigarette pack pushing magnetic overload protection device and a cigarette pack packaging machine to solve the above-mentioned problems. Utility Model Content

[0005] Based on the above, the purpose of this utility model is to provide a cigarette pack pushing magnetic overload protection device and a cigarette pack packaging machine, which solves the problem of misalignment of the cigarette pack pushing magnetic overload protection device due to excessive force, thereby improving the service life of the equipment and production efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] On one hand, a cigarette pack pushing magnetic overload protection device is provided, including a driving assembly. The driving assembly includes a driving member and a driving shaft extending along a first direction. 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 magnetic overload protection device further includes:

[0008] A connector, one end of which is connected to the drive shaft, and the other end of which is provided with a hinge groove;

[0009] A pack pusher rod has a first end hinged to the hinge groove, and the rotation axis of the pack pusher rod extends along the second direction. A pushing surface for pushing cigarette packs is provided on one side of the second end of the pack pusher rod. A first magnetic suction member is provided on the side wall of the pack pusher rod, and a second magnetic suction member is provided on the side wall of the hinge groove. When the pack pusher rod rotates relative to the connector to the pack pusher position, the pushing surface can push the cigarette packs, and the first magnetic suction member can be magnetically connected to the second magnetic suction member.

[0010] As a preferred technical solution for a cigarette pack pushing magnetic overload protection device, the hinge groove is provided with an avoidance opening on the side opposite to the cigarette pack along the first direction; the hinge groove is provided with a stop wall on the side close to the cigarette pack along the first direction.

[0011] As a preferred technical solution for a cigarette pack pushing magnetic overload protection device, a first magnetic element is provided on the side of the pushing rod near the stop wall, and a second magnetic element is provided on the stop wall.

[0012] As a preferred technical solution for a cigarette pack pushing magnetic overload protection device, the pusher rod is provided with a first mounting groove on the side near the stop wall, the first magnetic component is installed in the first mounting groove, the stop wall is provided with a second mounting groove, and the second magnetic component is installed in the second mounting groove.

[0013] As a preferred technical solution for a cigarette pack push magnetic overload protection device, the first magnetic component is bonded, snapped, or connected to the first mounting slot by fasteners; the second magnetic component is bonded, snapped, or connected to the second mounting slot by fasteners.

[0014] As a preferred technical solution for a cigarette pack pushing magnetic overload protection device, a hinge shaft extending in a second direction is provided in the hinge groove, and the pusher rod is hinged to the hinge shaft.

[0015] As a preferred technical solution for a cigarette pack pushing magnetic overload protection device, it also includes a detection sensor, which is used to detect the position of the pusher rod relative to the connector.

[0018] On the other hand, a cigarette packaging machine is provided, including the cigarette pack pushing magnetic overload protection device described in any of the above solutions.

[0019] The beneficial effects of this utility model are as follows:

[0020] This utility model provides a cigarette pack pushing magnetic overload protection device and a cigarette pack packaging machine. The connecting part and the pushing rod are configured as separate structures. During operation, the pushing rod rotates relative to the connecting part to the pushing position. The magnetic attraction of the first and second magnetic components creates a damping force between the pushing rod and the connecting part, providing overload protection. When the driving component drives the drive shaft to reciprocate, it in turn drives the pushing rod to move along a first direction, pushing the cigarette pack. When a deformed or severely loose cigarette pack moves to the front of the pushing rod, the resistance in front of the pushing rod exceeds the magnetic attraction between the first and second magnetic components. The pushing rod then overcomes the magnetic attraction and rotates relative to the connecting part. The pushing rod can automatically disengage when subjected to excessive force, protecting the cigarette pack pushing magnetic overload protection device from misalignment due to excessive force and preventing overload damage to the equipment, thus extending the equipment's service life. Afterwards, operators only need to remove the defective cigarette packs and operate the pushing rod to reset and rotate back to the pushing position. The first and second magnetic components then re-establish their magnetic connection. Operation is simple and production efficiency is improved. Attached Figure Description

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.

[0031] like Figures 1-3As shown, this embodiment provides a cigarette packaging machine, including a cigarette pack pushing magnetic overload protection device. This device includes a drive assembly, a connector 2, and a pushing rod 6. The drive assembly includes a drive member and a drive shaft 1 extending along a first direction. The drive member is driven and connected to the drive shaft 1, and is used to drive the drive shaft 1 to reciprocate along the first direction. One end of the connector 2 is connected to the drive shaft 1, and the other end is provided with a hinge groove 21. The first end of the pushing rod 6 is hinged to the hinge groove 21. The rotation axis of the pushing rod 6 extends along a second direction. One side of the second end of the pushing rod 6 is provided with a pushing surface 61 for pushing cigarette packs. A first magnetic attractor 3 is provided on the side wall of the pushing rod 6, and a second magnetic attractor 4 is provided on the side wall of the hinge groove 21. When the pushing rod 6 rotates relative to the connector 2 to the pushing position, the pushing surface 61 can push the cigarette packs, and the first magnetic attractor 3 can be magnetically connected to the second magnetic attractor 4. In this embodiment, the first direction is X, the second direction is Y, and the first direction is perpendicular to the second direction. The first magnetic attractor 3 and the second magnetic attractor 4 can be magnets.

[0032] The connector 2 and the pusher rod 6 are configured as separate structures. During operation, the pusher rod 6 rotates relative to the connector 2 to the pusher position. The magnetic attraction of the first magnetic 3 and the second magnetic 4 forms a damping force between the pusher rod 6 and the connector 2, providing overload protection. When the drive shaft 1 reciprocates, it drives the pusher rod 6 to move along the first direction. The pusher rod 6 can push the cigarette pack. When a deformed or severely loose cigarette pack moves to the front of the pusher rod 6, the resistance in front of the pusher rod 6 is greater than that of the first magnetic 4. When there is magnetic attraction between component 3 and the second magnetic component 4, the pusher rod 6 overcomes the magnetic attraction and rotates relative to the connector 2. The pusher rod 6 can automatically disengage when the force is too great, protecting the overload protection device for pushing cigarette packs from misalignment due to excessive force, and preventing overload damage to the equipment, thus improving the service life of the equipment. Subsequently, the operator only needs to remove the defective cigarette packs and operate the pusher rod 6 to reset and rotate to the pusher position. The first magnetic component 3 and the second magnetic component 4 will then re-establish their magnetic connection. 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] In this embodiment, a hinge shaft 5 extending in the second direction is provided in the hinge groove 21, and the first end of the push rod 6 extends into the hinge groove 21 and is hinged to the hinge shaft 5.

[0035] In this embodiment, the hinge groove 21 has a clearance opening 23 on the side facing away from the cigarette pack along the first direction; a stop wall 22 is provided on the side of the hinge groove 21 along the first direction and close to the cigarette pack. When the resistance of the unqualified cigarette pack in front of the pusher rod 6 is greater than the magnetic attraction force of the first magnetic suction member 3 and the second magnetic suction member 4, the pusher rod 6 rotates around the hinge axis 5 and rotates out through the clearance opening 23. When the operator drives the pusher rod 6 to reset, the pusher rod 6 rotates in the opposite direction until it abuts against the stop wall 22, which proves that the pusher rod 6 has rotated to the pusher position, improving the convenience of operation.

[0036] In this embodiment, a first magnetic attractor 3 is provided on the side of the pusher rod 6 near the stop wall 22, and a second magnetic attractor 4 is provided on the stop wall 22. The pusher rod 6 can withstand the maximum resistance. When the pusher rod 6 rotates to the point where the first magnetic attractor 3 is magnetically connected to the second magnetic attractor 4, it indicates that the pusher rod 6 has rotated to the pusher position.

[0037] Preferably, the pusher 6 is provided with a first mounting groove on the side near the stop wall 22, and the first magnetic suction member 3 is embedded in the first mounting groove. The stop wall 22 is provided with a second mounting groove, and the second magnetic suction member 4 is embedded in the second mounting groove. This reduces the distance between the pusher 6 and the stop wall 22, reduces the volume of the cigarette pack pushing magnetic overload protection device, and improves the installation stability of the first magnetic suction member 3 and the second magnetic suction member 4.

[0038] Furthermore, the first magnetic component 3 is bonded, snapped, or connected to the first mounting slot by fasteners, thus realizing the installation of the first magnetic component 3 in the first mounting slot; the second magnetic component 4 is bonded, snapped, or connected to the second mounting slot by fasteners, thus realizing the installation of the second magnetic component 4 in the second mounting slot.

[0039] Preferably, the overload protection device for the cigarette pack pushing magnetic attraction further includes a detection sensor 7, which is used to detect the position of the pusher rod 6 relative to the connector 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 pusher rod 6 to push the cigarette pack, the detection sensor 7 performs detection, and can detect whether the pusher rod 6 is located at the pushing position. When the resistance is too high, the pusher rod 6 can automatically disengage, and the detection sensor 7 detects that the pusher rod 6 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 pusher rod 6 can be manually reset, saving a lot of maintenance time. In this embodiment, the detection sensor 7 can be a proximity sensor, which is located on one side of the second end of the pusher rod 6 along the second direction. When the pusher rod 6 pushes the cigarette pack, the proximity sensor detects whether the pusher rod 6 is located at the pushing position. In other embodiments, the detection sensor 7 can be a photoelectric sensor, which can detect the position of the end of the pusher rod 6 used to push the cigarette pack.

[0040] In this embodiment, the top end of the connector 2 is provided with a connecting hole 24, and the side wall of the connecting hole 24 is provided with an opening 25. One of the two side walls opposite the opening 25 is provided with a third through hole, and the other is provided with a second threaded hole. The connecting hole 24 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 hole 24 is provided with a keyway 26, and a key is installed on the outer wall of the drive shaft 1. The key is embedded in the keyway 26, which can prevent the connector 2 from rotating relative to the drive shaft 1.

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.
