[0002] In tobacco cigarette making and packing production, generally, cigarette rods are conveyed between a tipping machine and a packing machine through the connection of auxiliary equipment, which is used for cigarette rod storage and transfer between the tipping machine and the packing machine. The blanking bin on the auxiliary equipment is used for temporarily storing the cigarette rods transported by the conveyor belt of the tipping machine; the cigarette rods in the blanking bin are then dropped and transferred to the packing machine, thus playing a buffering role in the process of transporting cigarette rods between the tipping machine and the packing machine and ensuring the production rhythm between the tipping machine and the packing machine.

[0003] In the actual production process, the packing machine and the tipping machine do not run at a completely constant speed. When there is a speed change, due to the inability of the cigarette rod conveying speed matching to respond quickly, there will be a situation of cigarette rod conveying interruption or over-blocking of cigarette rods in the auxiliary equipment. In the prior art, in order to adapt to the speed changes of the tipping machine and the packing machine, workers need to manually adjust the parameters of the auxiliary equipment every time to meet the buffering of the connection of cigarette rods between the two devices under variable speed conditions and avoid cigarette rod conveying interruption or over-blocking. This parameter adjustment method has a large labor intensity, a long manual adjustment time and may have adjustment errors, resulting in a reduction in the production efficiency of the cigarette making and packing workshop.

[0041] In addition, in the description of the present utility model, unless otherwise stated, the meaning of "a plurality of" is two or more.

[0042] Such as Figure 1 or Figure 2 , the blanking bin 8 is arranged between the tipping and packaging equipment on the cigarette making and packaging production line, and is used for storing and transferring cigarettes. It includes a feeding port 10 and a discharging port 11. At the feeding port 10, there are two parallel cigarette conveying belts 4. The cigarettes coming from the tipping equipment are conveyed by the cigarette conveying belts 4, enter the blanking bin 8 from the feeding port 10, and then go to the packaging equipment from the discharging port 11.

[0043] The automatic adjusting device of the blanking bin of the present utility model includes an adjusting plate 9, a push-pull rod 12, and a driving device 1 for driving the movement of the push-pull rod 12 (see Figure 3 ), one end of the adjusting plate 9 is connected to a rotating shaft 2, and the driving device 1 drives the adjusting plate 9 to rotate around the rotating shaft 2 through the push-pull rod 12 for adjusting the volume of the blanking bin 8. Specifically, the automatic adjusting device of the blanking bin further includes a tension spring 5 and a transmission structure 7. One end of the tension spring 5 is connected to the push-pull rod 12, and the other end is connected to the adjusting plate 9 through the transmission structure 7; the transmission structure 7 includes a sprocket 71 and a chain 72 that cooperate with each other. The sprocket 71 is fan-shaped, its center is installed on the rotating shaft 2, the sprocket 71 is fixedly connected to the adjusting plate 9, and the sprocket 71 drives the adjusting plate 9 to rotate together to realize the adjustment of the space size of the blanking bin 8; one end of the chain 72 is fixed on the sprocket 71, and the other end is connected to the push-pull rod 12 through the tension spring 5. The magnitude of the restoring force of the tension spring 5 is controlled by the telescopic movement of the push-pull rod 12. The restoring force of the tension spring 5 pulls the chain 72 to move, and the chain 72 drives the sprocket 71 to rotate, thereby driving the adjusting plate 9 to rotate according to the feeding and blanking states; the automatic adjusting device of the blanking bin 8 further includes a controller, which is respectively connected to the cigarette conveying belt 4 and the driving device 1, collects the start-stop signal and / or rotation speed signal of the cigarette conveying belt 4, and then outputs a signal to control the driving device 1 to make the adjusting plate 9 of the blanking bin 8 rotate around the rotating shaft 2 accordingly.

[0044] Such as Figure 3, the driving device 1 is installed on a fixed bracket 6, which facilitates the fixed installation of the driving device 1 at a suitable position on the cigarette packing production line. A connecting seat 13 is provided at the end of the push-pull rod 12, and the connecting seat 13 is connected to the tension spring 5, which facilitates the reliable installation of the tension spring 5 on the push-pull rod 12. The driving device 1 can be a linear actuator such as an electric push rod, a cylinder or a hydraulic cylinder. When the driving device 1 is an electric push rod, the electric push rod is directly connected to the controller, and the telescopic rod of the electric push rod constitutes the push-pull rod 12; when the driving device 1 is a cylinder or a hydraulic cylinder, the cylinder or the hydraulic cylinder is connected to the controller through the solenoid valve 3, and the solenoid valve 3 is communicated with the cylinder or the hydraulic cylinder through the pneumatic connector 31, and the piston rod of the cylinder or the hydraulic cylinder constitutes the push-pull rod 12.

[0045] The working process of the above-mentioned preferred embodiment of the present invention will be introduced in detail below:

[0046] As Figure 1 , when the cigarette enters the blanking bin 8 (feeding), the cigarette enters the blanking bin 8 from the feeding port 10 through the feeding belt. The upper conveying roller 41 of the cigarette feeding belt 4 rotates counterclockwise, and the lower conveying roller 42 of the cigarette feeding belt 4 rotates clockwise. The cigarette coming from the cigarette making and tipping equipment enters the blanking bin 8 under the driving action of the cigarette feeding belt 4, so as to realize the transmission and feeding of the cigarette. If the feeding speed is greater than the discharging speed, as the number of cigarettes in the blanking bin 8 increases, due to the elastic characteristics of the tension spring 5, the adjusting plate 9 can rotate clockwise around the rotating shaft 2 by a certain angle under the extrusion and gravity of the cigarettes in the blanking bin 8, and the volume of the blanking bin 8 becomes larger. At the same time, the tension spring 5 is stretched, and the pulling force of the tension spring 5 that hinders the clockwise rotation of the adjusting plate 9 also becomes larger, which may cause extrusion deformation of the cigarettes. Therefore, when the cigarette feeding belt 4 rotates, the controller in the present invention will collect the signal of the running state of the cigarette feeding belt 4. When the controller collects the signal of the running state of the cigarette feeding belt 4, it judges that it is necessary to expand the volume of the blanking bin 8 and outputs a signal to the solenoid valve 3. As Figure 3 shown, the solenoid valve 3 controls the cylinder to drive the push-pull rod 12 to extend through the pneumatic connector 31, the elongation of the tension spring 5 becomes smaller, and the pressure generated by the tension spring 5 on the cigarette through the adjusting plate 9 becomes smaller. That is to say, when the feeding belt runs, according to the starting or accelerating state of the cigarette feeding belt 4, the adjusting plate 9 of the automatic adjusting device of the blanking bin will automatically increase the angle of rotation clockwise, and the volume of the blanking bin 8 becomes larger, which is convenient for feeding and can prevent the cigarettes in the blanking bin 8 from being blocked during feeding.

[0047] As Figure 2, if the feeding speed is less than the discharging speed, including when the cigarette conveying belt 4 stops, as the number of cigarettes in the blanking bin 8 decreases, the outward thrust of the cigarettes in the blanking bin 8 on the adjusting plate 9 is less than the pulling force of the tension spring 5 on the adjusting plate 9, causing the adjusting plate 9 to rotate counterclockwise around the rotating shaft 2, reducing the volume of the blanking bin 8. The gradually erected adjusting plate 9 is conducive to cigarette blanking, but its response speed and action range are limited. To further prevent the interruption of cigarette transfer, when the conveying belt stops or runs at a reduced speed, the controller in the present utility model will collect the signal of the conveying belt stopping or running at a reduced speed, determine that the volume of the blanking bin 8 needs to be reduced, and output a signal to the solenoid valve 3. As Figure 3 shown, the solenoid valve 3 controls the cylinder through the pneumatic connector 31, causing the push-pull rod 12 to contract and the tension spring 5 to be stretched. The restoring force of the stretched tension spring 5 will increase, and the pulling force generated by the other end of the tension spring 5 on the adjusting plate 9 will increase. That is to say, when the cigarette conveying belt 4 stops or runs at a reduced speed, the adjusting plate 9 of the automatic adjusting device of the blanking bin will automatically increase the angle of rotation counterclockwise, further reducing the volume of the blanking bin 8, facilitating the rapid blanking of the cigarettes in the blanking bin 8, and preventing the occurrence of cigarette interruption.

[0048] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection scope of the present utility model.
