Description

Technical Field

[0001] The utility model belongs to the field of tobacco processing equipment, and particularly relates to an improved automatic label feeding device for a ZB25 soft-pack cigarette packing machine. Background Art

[0002] The ZB25 soft-pack cigarette packing machine is a mainstream medium-speed packing machine in China at present. Its maximum packing speed is 400 packs per minute, that is, 400 labels can be pasted per minute. The original label paper magazine is fixed. It takes about 5000 labels to completely fill this kind of label paper magazine (the thickness of label papers of different brands is different, so the number of labels added to the paper magazine is different). When the equipment runs at a speed of 380 packs per minute, labels need to be added about every 13 minutes (when there are about 1500 labels left, labels must be added, otherwise the positive pressure on the suction nozzle is not enough, resulting in the failure to suck down the label in time). The equipment runs for 8 hours in a normal shift, so the operator has to add labels at least 37 times. If there are problems with the raw and auxiliary materials of the labels, resulting in the inability to add more labels, the number of times the operator adds labels 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.

[0051] Among them, several connection cover plate mounting holes are provided on the connection cover plate (7a).

[0052] The working principle is:

[0053] 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 driving motor (3).

[0054] During use, the default state of the seal limit component (6) corresponding to the seal paper slot (1a) aligned with the material dropping bin (4) is that the "L"-shaped connecting rod of the driving device (15) compresses the label paper drag plate (6d) towards the fixed plate (6g), the first spring (6f) is compressed and has a pre-tightening force, and the label paper drag plate (6d) of the seal limit component (6) does not extend out of the sliding slot at the bottom of the seal paper slot (1a). The default state of the label paper drag plates (6d) corresponding to the remaining seal paper slots (1a) is that they extend out of the sliding slot at the bottom of the seal paper slot (1a), and the first spring (6f) is stretched. 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 down.

[0055] When the detection device (5) sends a paper shortage signal to the control system, the control system sends an instruction to the driving motor (3) to rotate one station. The drum hopper (1) rotates under the drive of the driving device. After the drum hopper (1) rotates 45 degrees, the driving motor (3) stops rotating, and a signal is sent to the driving device (15) through the control system. The next seal paper slot (1a) of the drum hopper (1) is aligned with the material dropping bin (4) again. The label paper drag plate (6d) corresponding to the next seal paper slot (1a) is compressed again by the "L"-shaped connecting rod of the driving device (15) towards the fixed plate (6g), the first spring (6f) is compressed and has a pre-tightening force, and the label paper drag plate (6d) retracts into the interior from the sliding slot at the bottom of the seal paper slot (1a). The seal paper (2) in the seal paper slot (1a) can be fed again until the amount of the seal paper (2) decreases to the low material level that the detection device (5) can detect, and then the next working cycle starts to continue working.

[0056] As the equipment operates, the number of seal papers (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 driving motor (3). The rotation of the driving 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). The position of the seal paper slot (1a) also changes accordingly.

[0057] The beneficial effects of the present utility model compared with the prior art are:

[0058] 1. The utility model reduces the labor intensity of the staff: By using an automated feeding device, compared with the frequent manual addition of sealing labels by the staff, the labor intensity of the staff is greatly reduced;

[0059] 2. The utility model significantly improves the work efficiency: Since the manual feeding process is reduced, the equipment can run continuously for a longer time without frequent shutdowns waiting for feeding, thus improving the work efficiency of the entire tobacco packaging process;

[0060] 3. The utility model can accurately control the feeding: By using a detection device to monitor the amount of sealing labels in the sealing label slot in real time, when the preset low level is reached, the drive motor is automatically triggered for feeding operation, ensuring the timely supply of sealing labels and avoiding production interruptions caused by insufficient sealing labels;

[0061] 4. The utility model can improve the production quality: Due to the timely supply and accurate control of the sealing labels, production quality problems caused by insufficient sealing labels or untimely feeding are reduced, such as poor adhesion or misalignment of the sealing labels.

[0140] In summary, a more specific embodiment of the present utility model is as follows:

[0141] Before the improved automatic label feeding device of the ZB25 soft box packaging machine with the above design structure is used, it needs to be installed as a standby.

[0142] The specific usage steps are as follows:

[0143] During the initial installation, the operator adjusts any one of the label 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 driving motor 3;

[0144] During use, in the default state of the label limiting component 6 corresponding to the label paper slot 1a aligned with the material dropping bin 4, the "L"-shaped connecting rod of the driving device 15 compresses the label paper drag plate 6d towards the fixed plate 6g, the first spring 6f is compressed and has a pre-tightening force, and the label paper drag plate 6d of the label limiting component 6 does not extend out of the sliding slot at the bottom of the label paper slot 1a. The default state of the label paper drag plates 6d corresponding to the remaining label paper slots 1a is to extend out of the sliding slot at the bottom of the label paper slot 1a, and the first spring 6f is stretched; when any one of the label paper slots 1a is aligned with the material dropping bin 4, the label paper 2 in the corresponding label paper slot 1a can accurately drop down;

[0145] When the detection device 5 sends a paper shortage signal to the control system, the control system sends an instruction to the driving motor 3 to rotate one station. The drum hopper 1 rotates under the drive of the driving device. After the drum hopper 1 rotates 45 degrees, the driving motor 3 stops rotating, and a signal is sent to the driving device 15 through the control system. The next label paper slot 1a of the drum hopper 1 is aligned with the material dropping bin 4 again, and the label paper drag plate 6d corresponding to the next label paper slot 1a is compressed towards the fixed plate 6g by the "L"-shaped connecting rod of the driving device 15 again. The first spring 6f is compressed and has a pre-tightening force, and the label paper drag plate 6d retracts into the internal part from the sliding slot at the bottom of the label paper slot 1a, and the label paper 2 in the label paper slot 1a can be fed down again until the amount of the label paper 2 decreases to the low material level that the detection device 5 can detect, and then the next working cycle starts to continue working.

[0146] As the equipment runs, the number of label papers 2 in the label 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 driving motor 3. The rotation of the driving 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 label paper slot 1a also changes its position accordingly.
