Background
The dyeing is a process of applying dye to a fabric, and enabling the fabric to have certain color and luster through physical or chemical change between the dye and fabric fibers. Dyeing and finishing are also called printing and dyeing, wherein the dyeing is heavy in color, the printing is heavy in color, and the printing is heavy, compared with the dyeing, the process accuracy requirement of the printing is relatively higher, the process emphasis is biased to be different, and therefore, the dyeing and the printing have different common equipment. Dyeing is generally carried out in a dye vat or pad dyeing is carried out by a pad mill. Printing, according to different printing principles, common equipment comprises spray printing equipment, rotary screen printing equipment and the like.
As one type of printing, double-sided printing is to print both sides of a fabric, and since the dyeing book belongs to double-sided dyeing, studies on double-sided printing are mainly directed at printing. As disclosed in patent document 201920178014.0, two printing mechanisms are sequentially arranged on a fabric conveying path, and the two printing mechanisms print on two sides of the fabric sequentially to realize double-sided printing. This kind of two-sided stamp structure, dislocation set around two stamp mechanisms, independent stamp respectively, two stamp mechanisms of independent stamp have great to the flower precision problem, can't accurate to the flower, are difficult to realize both sides with the stamp of counterpoint flower shape, and stamp limit nature is big.
For this reason, vertical double-sided printing apparatuses have been developed. The vertical double-sided printing equipment is mainly based on a rotary screen printing machine, and two rotary screens are arranged tangentially, so that the two rotary screens print fabrics synchronously from two sides of the fabrics. The rotary screen printing machine comprises a magnetic rod type rotary screen printing machine and a scraper type rotary screen printing machine, wherein a magnetic table is arranged on the opposite side of the rotary screen in the magnetic rod type rotary screen printing machine, and the rotary screens of the two magnetic rod type rotary screen printing machines cannot form a tangential position, so that vertical double-sided printing equipment consisting of the two magnetic rod type rotary screen printing machines does not exist at present; the existing vertical double-sided printing equipment adopts a scraper type rotary screen printing machine, as disclosed in patent document 200810197560.5 of Chinese patent application number. In a vertical double-sided printing device formed by tangent of two scraper type rotary screen printing machines, after the two rotary screens are tangent and synchronously rotate, the problem of the two-sided printing precision can be solved to a certain extent, but in the scraper type rotary screen printing machines, slurry in a circular screen hole is scraped onto a fabric through a scraper knife edge to the rotary screen, the scraper knife edge is contacted with a line between the rotary screens, the positions of the scrapers in the two scraper type rotary screen printing machines and the scraper pressure are not easy to control, the slurry feeding of the two rotary screens is easy to be uneven, thereby causing fabric color difference and affecting the dyeing quality; and the scraper edge and the cylinder are directly pressed and rubbed, so that the cylinder has large transmission friction force, is easy to break, has poor equipment stability and has short service life.
In addition, in theory, the double-sided printing equipment can also dye, but as described above, the uniformity of sizing by the existing double-sided printing mechanism is difficult to control, the existence of fabric color difference makes the actual production impossible to realize dyeing by double-sided printing, and the existing dyeing is basically carried out in a dye vat by the traditional dyeing method or padding by a padder. However, in the conventional dyeing method, a large amount of water is required for washing, so that water resource waste is serious and water pollution is severe.

In the double-sided cylinder printing and dyeing machine of the present invention, preferably, as shown in fig. 5, two infrared drying devices 201 are mounted on a set of linear guide rails 202 in a rolling manner, and are driven by a driving mechanism 200 to move along the linear guide rails 202, the linear guide rails 202 are parallel to the arrangement direction of the two infrared drying devices 201, the driving mechanism 200 includes two sets of link units 203 and a third cylinder 204, the two sets of link units 203 are distributed up and down, each set of link units 203 includes two links 2031 with hinged ends, the two links 2031 are V-shaped, the free ends of the two links 2031 are hinged to the two infrared drying devices 201 in a one-to-one correspondence manner, the two links 2031 of one set of link units 203 at one end of the third cylinder 204 are hinged to one point P1, and the other end of the third cylinder 204 is hinged to the two links 2031 of the other set of link units 203 at one point P2.
In the double-sided rotary screen printing and dyeing machine, the linear guide rail 202 is arranged on the frame of the infrared drying device. When in operation, the third cylinder 204 acts to drive the two connecting rods 2031 of the two groups of connecting rod units 203 to open or close, and further drive the two infrared drying devices 201 to move along the linear guide rail 202, so as to realize opening and closing.
The driving structure for realizing the opening and closing of the two infrared emitting devices 201 of the double-sided rotary screen printing and dyeing machine can be a linear driving transmission structure such as a cylinder, a worm gear and the like, or can be the structure. Compared with other structures, the driving mechanism 200 comprising the two groups of the connecting rod units 203 and the third air cylinder 204 has the advantages that on one hand, the height of the infrared drying device 201 is higher, under the condition that the height of the infrared drying device 201 is higher, the two groups of the connecting rod units 203 are respectively connected with the upper part and the lower part of the infrared drying device 201 for synchronous transmission, the synchronous transmission stress of the upper part and the lower part is more uniform, and the movement of the infrared drying device 201 is more stable; on the other hand, under this structure, the two ends of the third cylinder 204 are respectively connected with the two groups of connecting rod units 203, which are not required to be fixed with the linear guide 202 or the drying device frame, and the structure is simpler, and meanwhile, the whole horizontal movement of the two infrared drying devices 201 is convenient, the positioning or the dismounting is convenient, and the flexibility of use is higher.
In the double-sided rotary screen printing machine of the present invention, the drying device 20 further preferably includes a drying cylinder 210, and the double-sided printing unit 10, the infrared drying device 201, and the drying cylinder 210 are sequentially disposed along the fabric conveying direction. In operation, after being printed and dyed by the double-sided printing and dyeing unit 10, the fabric enters the infrared drying device 201, is pre-dried by the infrared drying device 201, then passes through the drying cylinder 210, and is further dried and fixed by the drying cylinder 210. The fabric tension is easily controlled and the fabric is not easily curled when the drying cylinder 210 is dried.
The double-sided cylinder printing machine of the present invention preferably further comprises a cloth feeding mechanism 30 and a cloth discharging mechanism 40, wherein the cloth feeding mechanism 30, the double-sided printing unit 10, the drying device 20 and the cloth discharging mechanism 40 are sequentially arranged along the fabric conveying direction.
It should be understood by those skilled in the art that the present invention may be embodied in many different forms without departing from the spirit or essential characteristics thereof.
