Description

Technical Field

[0001] The present invention relates to an overload protection device, specifically an overload protection device for a double push rod of a YB55 packaging machine, belonging to the technical field of cigarette manufacturing. Background Art

[0002] As is well known, the double push rod of the YB55 packaging machine plays a role in pushing cigarette packs during the normal operation of the equipment. It is divided into a front push rod and a rear push rod. The front push rod and the rear push rod are installed on the same shaft. The reciprocating movement of the shaft drives the left and right reciprocating cigarette pushing movements of the front push rod and the rear push rod. The function of the front push rod is to push the double-pack cigarettes lifted by the elevator into the ironing and sealing channel for ironing the cross-section of the cigarette pack. During the pushing process, the rear two packs of cigarettes will push the front two packs of cigarettes into the octagonal transfer turret. When the octagonal transfer turret rotates intermittently, unqualified cigarette packs will be removed. When the empty mold box after removal rotates to the next station, two qualified cigarette packs will be replenished into the empty mold box by the cigarette replenisher. The octagonal transfer turret continues to rotate intermittently. When it rotates to the entrance of the CT carton packaging machine, it will pause intermittently. When pausing, the rear push rod will push the double-pack cigarettes into the packaging station of the CT carton packaging machine.

[0003] Due to unexpected reasons, the equipment may occasionally produce cigarette packs with unqualified appearance during normal operation. When the cigarette packs with deformed appearance pass through the YB55 transparent paper packaging machine, loose cigarette packs will be generated; when the YB55 transparent paper packaging machine occasionally produces loose cigarette packs or deformed cigarette packs due to its own equipment reasons.

[0004] When the above-mentioned equipment failures occur, the defective cigarette packs will be removed at the removal station of the octagonal transfer turret. Since the removal process of this unqualified cigarette pack removal device is that the electromagnet action drives the rod dragging the cigarette pack away from the lower part of the cigarette pack, and the cigarette pack falls into the waste basket by its own gravity. This has a drawback that sometimes when the deformation or loose package is serious, it does not fall on time by its own gravity, and the octagonal turret starts to rotate. At this time, it will cause the defective cigarette packs to flow to the next process. When the octagonal turret rotates to the entrance of the CT carton packaging machine, the front push rod will push the cigarette pack into the CT packaging machine. Since the defective cigarette packs are not removed cleanly, blockage will occur during the pushing of the front push rod. At this time, the front push rod does not have an overload protection device. When the resistance is too large, the double push rod will be misaligned. After misalignment, the equipment cannot operate normally, and the maintenance personnel need to re-adjust and reset the phase of this double push rod, which is a waste of time.

[0005] At present, a Chinese utility model patent with the publication number CN213620399U discloses an overload protection device for a tobacco packaging machine, which includes a conveying channel with a U-shaped cross-section. A fixed baffle is provided at the open end of the conveying channel. It also includes a driving device for driving the baffle to reciprocate relative to the open end, so that the fixed baffle intermittently pats and moves the conveying channel. An adjustable baffle is hinged on the fixed baffle, and a torsion spring is provided between the adjustable baffle and the fixed baffle, so that the free end of the adjustable baffle away from the fixed baffle presses against the open end. A proximity switch is provided at the bottom of the conveying channel opposite to the free end. When the free end disengages from the conveying channel, the proximity switch disconnects to stop the equipment. This overload protection device is different from the scenario applied in this patent application, and there are also significant differences in structural features.

[0006] Therefore, the key to solving the above technical problems is to develop a practical and reliable overload protection device for the double-link push rod of the packaging machine. Summary of the Invention

[0136] In the present invention, the diameter of the steel ball 41 is greater than the thickness of the lower bottom plate of the installation groove of the fixed swing rod 1 or higher than the height of the steel ball connection hole 14; one end of the elastic piece 42 is also provided with a concave clamping portion adapted to be connected to the steel ball 41.

[0137] In summary, a more specific embodiment of the present invention is as follows:

[0138] During the normal operation of the device 5, due to unexpected reasons, occasionally unqualified cigarette packs in appearance may occur. When the deformed cigarette packs pass through the YB55 transparent paper packaging machine, unpacked cigarettes will be produced. Sometimes when the deformation or unpacking is serious and they do not fall by gravity on time, the octagonal turret starts to rotate. At this time, it will cause the defective cigarette packs to flow to the next process. When the octagonal turret rotates to the entrance of the CT carton packaging machine, the front push rod 55 pushes the cigarette packs into the CT packaging machine. Since the defective cigarette packs are not completely removed, blockage will occur during the pushing of the front push rod 55;

[0139] When the resistance is too large, due to the overload protection device of the present invention, after the connecting swing rod 2 presses the steel ball 41, one end of the connecting swing rod 2 disengages from the installation groove 11. At this time, the fixed swing rod 1 on the first connecting shaft 51 continues to rotate, while the connecting swing rod 2 stops rotating after disengaging from the steel ball 41. One end of the connecting swing rod 2 is connected to the push rod connecting shaft 57 through the connecting piece 54 and does not move, and the front and rear push rods at both ends of the push rod connecting shaft 57 also do not move. When the push time preset by the control device is exceeded, the machine will stop and a stop signal will be issued;

[0140] After the blockage fault is handled, at this time, the fixed swing rod 1 and the connecting swing rod 2 are misaligned. After the maintenance personnel readjust and reset the fixed swing rod 1 and the connecting swing rod 2, it can be used normally. The operator only needs to rotate the connecting swing rod 2 and move the connecting swing rod 2 into the installation groove 11. The connecting swing rod 2 will press down the steel ball 41. When the steel ball 41 is stuck into the connecting plate connection hole 22, the maintenance and adjustment work of the fixed swing rod 1 and the connecting swing rod 2 is completed. This maintenance and adjustment work is fast, efficient, time-saving and labor-saving.

[0141] Embodiment 2

[0142] Embodiment 2 is basically the same as Embodiment 1. The only difference is that a detector 6 is further provided on the outer wall of the housing of the device 5; due to the additional detector 6, when the detector 6 fails to detect the rear pushing bag rod 56 within a predetermined threshold, it will immediately send a signal to the control device, and the control device will immediately send a signal to stop the machine and display the shutdown information of "double-link pushing bag rod blockage" of the present invention on the display screen, greatly shortening the reaction time of the control device. At the same time, the blockage fault mode and the reset mode when the fixed swing rod 1 and the connecting swing rod 2 are misaligned are the same as those in Embodiment 1;

[0143] More specifically, if the detector 6 fails to detect the rear pushing bag rod 56 within the set predetermined interval, it will send a signal to the control device of the device 5. The control device will immediately issue a stop alarm and display "double-link pushing bag rod blockage" on the display screen, and the control device 5 will perform the shutdown work;

[0144] If the detector 6 detects the rear pushing bag rod 56 within the set predetermined interval, the device will maintain normal operation;

[0145] Specifically, the detector 6 can detect the position where the rear pushing bag rod 56 passes and the stroke of the rear pushing bag rod 56. For example, the presence of the rear pushing bag rod 56 should be detected between 30 degrees and 120 degrees. At this time, the device operates normally; if the rear pushing bag rod 56 is not detected within this angle range, it means that the stroke of the rear pushing bag rod 56 is incorrect, and then the machine will stop immediately and alarm, and display "double-link pushing bag rod blockage" on the external display screen.

[0146] In the present invention, the detector 6 is used to detect whether the rear pushing bag rod 56 is within a preset detection angle range.

[0147] Embodiment 3

[0148] As shown in the attached Figures 9 to 13 As shown in the figure, Embodiment 3 is basically the same as Embodiment 2. The only difference is that an auxiliary resetting member 7 is further provided on the connecting plate 53 at the lower part of one end of the guide plate 52; when the operator sees the shutdown information of "double-link pushing bag rod blockage" displayed on the display screen;

[0149] After the blockage fault is handled, the reset method for connecting the swing rod 2 and the fixed swing rod 1 is as follows: when the connecting swing rod 2 and the fixed swing rod 1 are not on the same axis, the operator drives the fixed swing rod 1 to rotate by rotating the connecting part below the first connecting shaft 51, thereby driving the connecting swing rod 2 rotatably connected to the fixed swing rod 1 to move. When the connecting swing rod 2 rotates to contact the auxiliary reset member 7, at this time, the auxiliary reset member 7 serves as a limiting member, so that the contact end of the connecting swing rod 2 and the auxiliary reset member 7 no longer moves. The operator continues to rotate the fixed swing rod 1, so that the connecting plate engagement hole 22 of the connecting swing rod 2 is snapped onto the steel ball 41 on the fixed swing rod 1, thereby completing the rapid reset of the connecting swing rod 2 and the fixed swing rod 1.

[0150] In the present invention, the auxiliary reset member 7 is used to assist the connecting swing rod 2 and the fixed swing rod 1 to be reset, and they are on the same axis after reset; a connecting plate threaded hole adapted to the auxiliary reset bolt is provided on the connecting plate 53. After the auxiliary reset bolt is threadedly connected to the connecting plate 53, the auxiliary reset bolt is locked by a locking nut.

[0151] In the present invention, an overload protection device is provided on the device 5. When the device 5 is running and the resistance is too large, the fixed swing rod 1 and the connecting swing rod 2 can be automatically disengaged, and the detector 6 detects that the fixed swing rod 1 and the connecting swing rod 2 are disengaged and stops the machine. After the operator handles the equipment blockage fault and turns the equipment, it can be quickly and automatically reset through the cooperation with the auxiliary reset member 7, which is very convenient and saves time.

[0152] When the current pushing package rod 55 is overloaded during cigarette extrusion, the position of the existing swing rod relative to the first connecting shaft 51 will change. Because the existing swing rod is held tightly on the first connecting shaft 51 by an 8MM screw, when the overload force exceeds the holding force, a relative position change will occur, that is, the misalignment mentioned in the background technology. If the existing swing rod is damaged, to replace the swing rod, this first connecting shaft 51 needs to be removed for replacement, and the workload is very large; the present invention designs the existing swing rod into a split structure. When the connecting swing rod 2 of the overload protection device is damaged and needs to be replaced, only the pin 31 of the limiting component 3 needs to be disassembled, and then only the connecting swing rod 2 needs to be replaced, and the fixed swing rod 1 connected to the first connecting shaft 51 later does not need to be replaced, greatly saving the maintenance time and material loss.

[0153] Finally, it should be noted that the above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution content of the present invention still belong to the protection scope of the technical solution of the present invention.
