Description

Technical Field

[0001] The invention relates to a nonwoven fabric production technology, in particular to a double-row soft towel machine. Background Art

[0002] The non-woven fabric industry has achieved great development in recent years. Its application in sanitary absorbent materials, medical materials, and transportation textile materials has increased significantly. The large demand for non-woven fabrics has led to the continuous updating and improvement of non-woven fabric manufacturing equipment.

[0003] At present, most medical non-woven fabrics need to be folded. After the large roll of non-woven fabric is cut into narrow non-woven fabrics by a slitting machine, it is folded and then rolled up. At present, the production mode of single machine single roll or multiple machines multiple rolls is adopted. The existing technology has the problems of low efficiency of single roll winding and uneven and difficult to adjust multi-roll winding.

[0004] For example, the patent non-woven double-roll soft towel machine 2019109262623 applied by the applicant discloses a dual-channel winding soft towel machine, including roll feeding, slitting, punching and winding. The whole roll of cloth is unrolled and cut into two pieces of the same size for work, which means that it can only be cut and used, and two pieces of the same size cannot be combined and used together. Summary of the invention

[0005] The technical problem to be solved by the present invention is to propose a double-row soft towel machine which can realize the division into two and the merging of two rolls in view of the deficiencies in the prior art.

[0006] The technical problem to be solved by the present invention is achieved through the following technical solutions: a double-row soft towel machine, a non-woven fabric roll positioning feeding mechanism, a slitting mechanism, a forming mechanism, a point breaking mechanism, a rear traction mechanism and a winding mechanism, which are characterized by:

[0007] The non-woven fabric roll positioning and feeding mechanism includes a front bracket and a material carrying shaft installed on the front bracket, two bearing sleeves are arranged side by side on the material carrying shaft, and baffles for blocking the material are arranged at both ends of each bearing sleeve, and the baffles rotate with the shaft sleeve, and two pneumatic feeding arms for pressing the raw materials are arranged corresponding to the bearing sleeves, the feeding arms are hinged to the front bracket through a hinge shaft, and the hinge shafts of the two feeding arms are coaxially arranged, and a material pressing roller is arranged at the free end of the feeding arm, and a transmission shaft is coaxially arranged with the above-mentioned hinge shaft, and a feeding belt is arranged between the material pressing roller and the transmission shaft, and a second transmission shaft is arranged at the rear of each transmission shaft, the second transmission shaft is arranged parallel to the transmission shaft, and the two second transmission shafts are coaxially arranged, and the second transmission shaft is connected to the transmission shaft through a stepless speed change mechanism, and the two second transmission shafts are connected to the main transmission shaft through two sets of independent sprocket chains for transmission.

[0008] The technical problem to be solved by the present invention can be further achieved by the following technical solution: a material lifting mechanism is provided at the front bracket.

[0009] The technical problem to be solved by the present invention can be further achieved through the following technical scheme: the material lifting mechanism is provided with a material lifting arm, a swing arm is provided at the lower part of the material lifting arm, the swing arm is hinged to the front bracket, and a material lifting cylinder for driving the swing arm to swing is provided on both sides of the front bracket.

[0010] Compared with the prior art, the present invention has two sprockets installed on the main transmission shaft, which are respectively transmitted to one end of two independent second transmission shafts, and the other end is installed with a continuously variable speed wheel, which is then transmitted to the flat belt conveyor arm, so that the two cloth rolls of 1+1 can be combined and unwound independently, and the tension is adjusted by two continuously variable speed wheels. When not making 1+1 double-roll raw materials, the shaft sleeve on the material bearing shaft is replaced and a roll of whole material is installed, and the one-to-two working mode can also be used.
