Description

Technical Field

[0001] The utility model relates to the field of paper towel production, in particular to a paper towel production line. Background Art

[0002] Paper towels are widely used in many fields such as home hygiene and catering because they are easy to carry and have cleaning capabilities. In order to improve the aesthetics of paper towels, paper towels on the market are usually printed with exquisite patterns or texts to attract consumers' attention and purchase. However, such patterned paper towels are usually purchased from raw paper rolls with printed patterns, which are then cut and folded and put into packaging. However, since the positions of these patterns or texts on the paper towels are usually different after cutting, the patterns or texts on the raw paper rolls need to be designed in a repeated and cyclical printing form, which is difficult to meet the customization needs of customers. At the same time, the patterns or texts printed on paper towels in the same package are all the same, which is relatively simple and lacks interest, and can no longer meet the needs of current consumers.

The utility model discloses a paper towel production line, including a paper feeding device 1, a folding device 2, a printing device 3, a flattening device 4, a large rotary cutting device 5 and a conveyor line connected in sequence. The paper feeding device 1 is used to transport raw paper, and it usually includes a roller that can mount a paper roll. When the roller rolls, the paper roll releases the raw paper. The folding device 2 is arranged at the discharge end of the paper feeding device 1, and a cutting component for cutting the raw paper into a specified length and a folding component for folding the cut single raw paper are usually arranged inside. This is a conventional technical means and will not be repeated.

[0029] The printing device 3 is arranged on both sides of the folding device 2, and includes a plurality of printing nozzles 31. The printing nozzles 31 spray ink onto the raw paper, thereby printing patterns or texts into the target area on a single raw paper. The flattening device 4 is arranged behind the folding device 2 to compact and flatten the folded raw paper. The large rotary cutting device 5 is arranged behind the flattening device 4 to cut the compacted raw paper into paper towel stacks with a fixed width. The conveyor line sends the paper towel stacks into the packaging device and the sealing device in sequence. The packaging device puts the paper towel stacks into a package, which can be a soft package or a hard package. The sealing device puts a plurality of finished paper towel stacks that have been packaged into a structure such as a carton, thereby forming a final sales product.

[0030] The print head 31 is arranged on the mounting frame 32, and a nozzle protection assembly is also arranged on the print head 31. The nozzle protection assembly includes a protective cover 33 and a driving source, and the driving source drives the protective cover 33 to move closer to or away from the printing end of the print head 31. The driving source includes a lifting motor 34 and a translation motor 35, the output end of the lifting motor 34 is arranged on the print head 31, and its body reciprocates along the inkjet direction of the print head 31, the body of the translation motor 35 is fixedly connected to the body of the lifting motor 34, and the output end of the translation motor 35 drives the protective cover 33 to move.

[0031] The protective cover 33 is provided with a sealing ridge 331. When the protective cover 33 is placed on the print head 31, the sealing ridge 331 surrounds the outer periphery of the print head 31. When the print head 31 is not in use, in order to prevent the ink from drying up and causing the print head to be blocked, the translation motor 35 is started to align the protective cover 33 with the print head 31 in the vertical direction, and then the lifting motor 34 is started to move the protective cover 33 closer to the print head 31, and finally the protective cover 33 is placed on the print head 31. When the print head 31 needs to be used, the lifting motor 34 is used to move the protective cover 33 away from the print head 31, and then the translation motor 35 is used to move the protective cover 33 further away from the print head 31.

[0032] The protective cover 33 is also connected to the water spray assembly. When the protective cover 33 is covered on the print nozzle 31, the water spray assembly sprays water to the ink outlet end of the print nozzle 31, thereby improving the cleaning effect and preventing ink clogging. The protective cover 33 is provided with a plurality of concave water storage tanks 332, and the water storage tanks 332 are all located in the area surrounded by the sealing ridges 331, so that excess water after cleaning flows into the water storage tanks 332, avoiding affecting the subsequent inkjet printing or dripping of sewage. The printing device 3 also includes a centralized ink supply system, which is connected to the print nozzle 31 to supply ink to the print nozzle 31.

[0033] As a preferred embodiment, since there are various packagings of paper towels, if a production line is set for each paper towel of different packaging, a large amount of factory area will be occupied, and a large equipment and labor cost will be generated. In order to make the production line structure simple and compact, the production line also includes a lane dividing device 6, and the conveying line includes a first conveying line 71 and a second conveying line 74. The lane dividing device 6 is provided with an inlet connected to the large rotary cutting device 5, and the lane dividing device 6 is provided with two outlets.
