Description

Technical Field

[0001] The utility model belongs to the field of tobacco processing equipment, and particularly relates to a simple automatic feeding device for seals of a ZB25 soft-packaging machine. Background Art

[0002] The ZB25 soft-packaging machine is a mainstream medium-speed packaging machine in China at present. Its maximum packaging speed is 400 packs per minute, that is, 400 seal stickers can be pasted per minute. The original seal sticker magazine is fixed. It takes about 5000 seal stickers to completely fill this kind of seal sticker magazine (the thickness of seal stickers of different brands is different, so the number of seal stickers added to the magazine is different). When the equipment runs at a speed of 380 packs per minute, seals need to be added about every 13 minutes (seals must be added when there are about 1500 left, otherwise the positive pressure on the suction nozzle is not enough, resulting in the seals not being sucked down in time). A normal shift of the equipment runs for 8 hours, so the operator has to add seals at least 37 times. If there are problems with the raw and auxiliary materials of the seals and more seals cannot be added, the number of times the operator adds seals per shift will far exceed 37 times, and can even reach between 60 and 90 times. This increases the labor intensity of the operator and greatly affects the work efficiency.

[0116] In summary, a more specific implementation manner of the present utility model is:

[0117] Before using a simple ZB25 soft box packaging machine sealing label automatic feeding device with the above design structure, it needs to be installed for standby.

[0118] The specific usage steps are:

[0119] During the initial installation, the operator adjusts any one of the seal paper slots 1a of the storage drum 1 to the phase aligned with the material dropping slot of the material dropping bin 4 through the drive motor 3;

[0120] During use, the default state of the seal limiting component 6 corresponding to the seal paper slot 1a aligned with the material dropping bin 4 is that the bottom roller closely adheres to the groove of the seal fork support base 14, the first spring 6b is stretched, and the fork needle 6c of the seal limiting component 6 does not protrude from the seal paper slot through hole at the bottom of the seal paper slot 1a. The fork needles 6c of the seal limiting components 6 corresponding to the remaining seal paper slots 1a are in the default state of protruding from the seal paper slot through holes at the bottoms of the seal paper slots 1a, and the first spring 6b is compressed and has a pre-tightening force; when any one of the seal paper slots 1a is aligned with the material dropping bin 4, the seal paper 2 in the corresponding seal paper slot 1a can accurately drop downward;

[0121] When the detection device 5 sends a paper shortage signal to the control system, the control system sends an instruction to the drive motor 3 to rotate one station. The drum hopper 1 rotates under the drive of the driving device. When the drum hopper 1 rotates 45 degrees, the drive motor 3 stops rotating, and the next seal paper slot 1a of the drum hopper 1 is aligned with the material dropping bin 4 again. The third roller 6a of the seal limiting component 6 corresponding to the next seal paper slot 1a moves into the groove of the seal fork support base 14 again, and the first spring 6b rebounds to retract the fork needle 6c from the seal paper slot through hole at the bottom of the seal paper slot 1a. The seal paper 2 in the seal paper slot 1a can be fed downward again until the quantity of the seal paper 2 decreases to the low material level that can be detected by the detection device 5, and then the next working cycle starts to continue working.

[0122] As the equipment operates, the quantity of the seal paper 2 in the seal paper slot 1a gradually decreases, and the material level gradually drops. When it drops to trigger the detection device 5, that is, the photoelectric detector, the detection device 5 sends an electrical signal to control the movement of the drive motor 3. The rotation of the drive motor 3 drives the rotation of the transmission gear assembly 9, then drives the rotation of the first driven assembly 10 and the second driven assembly 11, and finally drives the rotation of the drum hopper 1, and the seal paper slot 1a also changes its position accordingly.

[0123] During the above use process, the operator can calculate the total time for adding all the seal paper 2 in the storage drum 1 according to the time when all the seal paper 2 in the storage drum 1 is added. After that, the paper adding time of the seal paper 2 in the storage drum 1 can be reasonably arranged, which greatly reduces the labor intensity of the staff.

[0124] Finally, it should be noted that the above description is only a preferred embodiment of the present invention, and it is not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content 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 fall within the protection scope of the technical solution of the present invention.
