Description

Technical Field

[0001] The utility model relates to a buffer device, in particular to a cigarette pack conveying channel buffer device, belonging to the technical field of cigarette manufacturing. Background Art

[0002] The existing ZB25 / ZB45 packaging units are composed of small box packaging machines, small box transparent paper packaging machines, strip box trademark paper packaging machines, and strip box transparent paper packaging machines. The qualified cigarette packs produced by the small box packaging machine are transported to the small box transparent paper packaging machine through the cigarette pack conveying channel. Since the cigarette pack conveying channel is relatively long, when the small box transparent paper packaging machine stops for paper replacement or fails, the main machine will not stop, but will continue to produce until the cigarette pack conveying channel is full. At this time, the small box transparent paper packaging machine will continue to start after the fault is handled. Since the conveyor belts of the cigarette pack conveying channel are driven by fixed-frequency motors, that is to say, no matter how fast the packaging speed of the equipment is, the speed of the conveyor belts of the conveying channel is consistent, so at this time, the cigarette packs on the conveyor belt at the back will exert great pressure on the cigarette packs and conveyor belts at the entrance of the small box transparent paper packaging machine. If it is a soft pack cigarette, it will cause the cigarette packs to deform and the aluminum foil on the top of the cigarette packs to deform, resulting in product appearance. Quality defects; if it is a hard box cigarette pack, it will cause a great thrust on the conveyor belt in front of the C600 turntable. The function of the conveyor belt in front of the C600 is to slow down and separate the continuous cigarette packs, and then the single cigarette packs will be sucked by the suction foot of the C600 for conveying and turning into the cigarette feeding channel of the small box transparent paper packaging machine. Because there are too many cigarette packs in the cigarette pack channel, the forward thrust is too large, so the conveyor belt in front of the C600 must be adjusted very tightly, otherwise the cigarette packs will move forward, and the phase of the suction foot of the C600 sucking the cigarette packs will change. When conveying and turning into the cigarette feeding channel of the small box transparent paper packaging machine, cigarettes will be stuck, causing equipment shutdown or jamming the lug conveyor belt. If the conveyor belt in front of the C600 is adjusted very tightly, it will cause the cigarette packs to deform. Product quality defects will also cause the conveyor belt to wear faster, resulting in frequent replacement of the conveyor belt, resulting in the consumption of a large number of spare parts, and increased maintenance costs and maintenance time.

[0003] At present, the Chinese utility model patent with the announcement number CN213139244U discloses a cigarette conveying buffer device, including a conveyor belt and buffer components arranged on both sides of the upper end of the conveyor belt, the buffer components include buffer belts rotatably arranged on both sides of the conveyor belt, and buffer sheets arranged in the buffer belt to press the buffer belt against the upper side of the conveyor belt, and the spacing between the two buffer belts is less than the length of the cigarette. The device has a low degree of automation and a small range of application.

[0057] 6. The buffer motor of the utility model can also be connected to an external solenoid valve, and then the output shaft of the buffer motor body is controlled by the external solenoid valve to change the direction, thereby slowing down too many cigarette packs from entering the rear conveying channel, causing excessive pressure on subsequent downstream equipment, resulting in equipment damage or product quality degradation.

[0116] In the present invention, the buffer motor 33 can change the rotation speed of the buffer motor body through the control device 2 .

[0117] In summary, a more specific implementation method of the present invention is:

[0118] Before using the cigarette packet conveying channel buffer device of the above-mentioned design structure, it is necessary to install it as a backup.

[0119] The specific steps are:

[0120] When the third detector 53 detects a cigarette pack 6 at the corner of the conveying channel 1, the third detector 53 sends a signal to the control device 2, and the control device 2 gives a signal to the buffer motor 33 to make the buffer motor 33 rotate a little slower; if the third detector 53 does not detect a cigarette pack 6, it sends a signal to the control device 2, and the control device 2 gives the buffer motor 33 a signal current to make the motor rotate faster to speed up the replenishment of the cigarette pack 6;

[0121] Two first detectors 51 and a second detector 52 are installed in the original conveying channel 1, which are connected to the control device 2, and then the action of the adjustment component 4 is controlled by the control device 2; when the first detector 51 does not detect the cigarette pack 6, but the second detector 52 detects the cigarette pack 6, the friction force of the buffer belt 325 of the buffer device 3 can buffer the thrust of the cigarette pack 6 in the conveying channel of the cigarette pack 6. When the first detector 51 and the second detector 52 both detect the cigarette pack 6, it means that there are too many cigarette packs 6 in the conveying channel 1. At this time, the front first detector 51 and the second detector 52 will send a signal to the control device 2, and the control device 2 controls the solenoid valve 43 to perform the reversing action of the adjustment cylinder 42. The adjustment cylinder 42 drives the adjustment block 321 connected thereto to move toward the other buffer unit 32 through the connecting plate 44, thereby reducing the distance between the two buffer belts 325 and increasing the pressure on the cigarette pack 6. In this way, the buffer device 3 will buffer all the excessive thrust and will not directly act on the conveyor belt before C600.

[0122] During use, when the first detector 51 and the second detector 52 detect that there are too many cigarette packs 6 in the conveying channel 1, the first detector 51 sends a speed signal to the control device 2, and the control device 2 controls the motor to slow down, so that the buffer motor 33 drives the buffer transmission belt 325 to decelerate, thereby slowing down too many cigarette packs 6 entering the rear conveying channel 1, resulting in excessive pressure on subsequent downstream equipment, causing equipment damage or product quality degradation.

[0123] Finally, it should be noted that the above is only a preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the content of the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
