Description

TECHNICAL FIELD

[0001] The application relates to the technical field of packaging machines, in particular to a belt automatic joint and continuous conveying device for a cotton-soft-wipe bag making machine. BACKGROUND

[0002] With the upgrading of the flexible packaging industry automation, especially the rapid growth of the demand for bag making of disposable sanitary products such as cotton-soft-wipe, the continuous, stable and efficient conveying of the packaging belt (roll material) by the bag making machine is put forward with higher requirements. In the prior art, the cotton-soft-wipe bag making machine usually relies on an independent unwinding mechanism to release the belt, which is guided and transmitted by a multi-stage conveying roller group, and the positioning of the belt at the bag making station (such as heat sealing and slitting) is realized by combining servo drive and PLC control.

[0003] However, the existing belt conveying device still has the following significant bottlenecks when applied to the cotton-soft-wipe bag making scene:

[0004] Roll change interruption and repeated belt threading: the biggest pain point of the existing device is the replacement process after the roll material is exhausted. When a roll of belt material is used up, the machine must be stopped, the old roll tail end is cut by hand, the new roll end is manually threaded through the complex conveying roller path, and is preliminarily fixed (such as glued or knotted) with the old belt. This process is not only complicated, time-consuming and labor-intensive, resulting in long equipment downtime, which seriously affects the continuity and efficiency of the bag making production line, especially under high production capacity requirements.

[0005] Insufficient tension control adaptability: cotton-soft-wipe packaging belt materials have various materials (such as non-woven fabric, composite film, etc.), and their friction coefficients, elasticity and stiffness differ significantly. The multi-stage roller group of the existing conveying device is usually rigidly connected, and the tension adjustment mechanism is not flexible enough. For the belt material with smooth surface, it is easy to slip on the roller due to insufficient friction, causing unstable conveying; and for high-elasticity materials, uneven tension easily causes excessive stretching and deformation or relaxation and wrinkling of the belt material, which seriously affects the quality and precision of subsequent bag making (such as heat sealing).

[0006] Belt wrinkling problem: ultra-thin or soft cotton-soft-wipe belt material is prone to wrinkling during conveying due to unreasonable path or uneven local tension. The existing device lacks targeted wrinkle removal structure, which causes wrinkled belt material to enter the bag making station, directly affecting the appearance flatness and sealing strength of the final bag.

[0007] The degree of automation and intelligentization needs to be improved: the existing device generally lacks highly automated solutions in the aspects of roll material remaining amount monitoring, automatic recognition and connection of new and old belt material ends, and automatic processing of waste materials after connection, which still requires more manual intervention.

Figure 7 Finally, the end of the strip 33 passes between the driving roller 241 and the driven roller 32, the threaded rod one 28 is rotated, so that the driven roller 32 can tightly press the strip 33 on the driving roller 241, and finally the end of the strip 33 passes between the cutter plate 254 and the protective cover 251.

[0065] When the machine is working normally, the motor 26 pulls the strip 33 to move at a constant speed to the right through the belt transmission mechanism. When the scanner 23 identifies the color card on the outer surface of the strip 33, the external single-chip microcomputer controls the electric telescopic rod five 252 to press down the cutting knife 253. The cutting knife 253 cuts off the strip 33. The cut-off packaging bag is lifted by the bag lifting mechanism and then enters the bag filling process.

[0066] When the left material roll is unwound, the laser receiver 14 receives the light signal emitted by the laser emitter 15. The external single-chip microcomputer controls the electric telescopic rod two 176 on the left to extend and press the tail of the strip 33 against the outer surface of the roller five 171.

[0067] Then, the stud two 1112 is loosened to move the material roll loading device 11 on the left after unwinding to the right. The end of the new strip is placed on the upper surface of the support table 174 after being wound around the roller five 171 on the right from below. To ensure that the ends of the two material rolls are stacked together, the electric telescopic rod two 176 on the right is extended to press the head of the new strip against the outer surface of the roller five 171. The electric telescopic rod one 172 is extended to press the heated electric nickel-chromium alloy strip 175 against the stacked strip, so that the stacked strip is bonded together. The code marking machine 173 is started at the same time to mark the overlapping part for easy identification.

[0068] After the material roll is combined, when the marked position moves to the scanner 23, the scanner 23 identifies the code. Then, the connecting part is cut off by the cutting device 25. The cut-off connecting part is sucked by the negative pressure suction nozzle 105 and then moved into the waste box.

[0069] It is worth noting that the input ends of the deviation correcting device 5, the motor two 101, the electric telescopic rod three 102, the electric telescopic rod four 103, the laser receiver 14, the laser emitter 15, the electric telescopic rod one 172, the code marking machine 173, the electric nickel-chromium alloy strip 175, the electric telescopic rod two 176, the scanner 23, and the motor 26 are electrically connected to the output end of the external power supply through the external single-chip microcomputer.

[0070] The single-chip microcomputer controls the deviation correcting device 5, the motor two 101, the electric telescopic rod three 102, the electric telescopic rod four 103, the laser receiver 14, the laser emitter 15, the electric telescopic rod one 172, the code marking machine 173, the electric nickel-chromium alloy strip 175, the electric telescopic rod two 176, the scanner 23, and the motor 26 to work, which adopts a common scheme in the existing technology.

[0071] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are merely exemplary and that changes can be made in detail without departing from the principles and spirit of the application. The scope of the application is therefore defined by the appended claims and their equivalents.
