DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1

[0031] The present embodiment discloses a double-width cloth-feeding printing device, as shown in Figures 1 and 2, comprising a cloth feed roller group 1, a cloth feed roller group 2 and a printing device 2. The cloth feed roller group 1 and the cloth feed roller group 2 are both mounted on a frame 1 of the device to transport the cloth. The cloth feed roller group 1 and the cloth feed roller group 2 can form two cloth transport routes.

[0032] 1 , the cloth feed roller group works together to transport the cloth 19. The cloth 19 is input from the cloth loading device 11, guided and transported by the cloth feed roller group 1, and then input to the printing device 2 for printing.

[0033] 2 , the cloth feed roller group 2 plays a role in conveying the cloth 29 . The cloth 29 is input from the cloth loading device 21 , guided and conveyed by the cloth feed roller group 2 , and then input to the printing device 2 for printing.

[0034] Feed roller group 1 and fabric roller group 2 are arranged side by side along the width direction. Feed roller group 1 and feed roller group 2 can operate independently and simultaneously transport fabric 1 19 and fabric 2 29, achieving double-width fabric feeding. Fabric 1 19 and fabric 2 29 can be simultaneously input into printing device 2, which can perform dual-width printing on fabric 1 19 and fabric 2 29. This printing equipment can process two sets of fabrics simultaneously. Each component of feed roller group 1 and feed roller group 2 is installed in frame 1, and the sum of the widths of feed roller group 1 and feed roller group 2 does not exceed the width of frame 1, allowing fabric 1 19 and fabric 2 29 to be transported side by side, achieving double-width fabric feeding and double-sided printing.

[0035] The cloth feed roller group 1 includes a plurality of guide rollers 18, each guide roller 18 is arranged along the conveying route of the cloth 19, and the guide roller 18 can allow the cloth 19 to bypass and further guide the cloth 19 so that the cloth 19 can be conveyed smoothly and stably.

[0036] The cloth feed roller group 2 includes several guide rollers 28, each of which is arranged along the conveying route of the cloth 29. The guide rollers 28 can allow the cloth 29 to bypass and then guide the cloth 29 so that the cloth 29 can be conveyed smoothly and stably.

[0037] In order to provide power for conveying cloth 19 and cloth 2 29, the cloth feed roller group 1 includes a traction roller 12, and the cloth feed roller group 2 includes a traction roller 2 22. The traction roller 12 and the traction roller 2 22 are respectively driven to rotate by two independent drives, thereby being able to provide power to cloth 19 and cloth 2 29 at the same time.

[0038] The traction roller 12 is driven to rotate actively by a driver 1. A pressure roller 13 is provided on the outside of the traction roller 12. The pressure roller 13 can press against the outer periphery of the traction roller 12. The pressure roller 13 can press the cloth 19 against the outer periphery of the traction roller 12, thereby providing power for the conveyance of the cloth 19 and ensuring smooth and stable conveyance of the cloth 19.

[0039] The second traction roller 22 is driven to rotate actively by the second driver. A second pressure roller 23 is provided on the outside of the second traction roller 22. The second pressure roller 23 can press against the outer periphery of the second traction roller 22. The second pressure roller 23 can press the second cloth 29 against the outer periphery of the second traction roller 22, thereby providing power for the transportation of the second cloth 29 and ensuring smooth and stable transportation of the second cloth 29.

[0040] In order to maintain the stability of fabric conveying and to have a good tension state during the conveying process, tension adjustment devices are installed in the cloth feed roller group 1 and the cloth feed roller group 2. The tension adjustment rollers are driven by cylinders to maintain a stable tension state of the fabric and ensure stable and smooth fabric conveying.

[0041] Specifically, the cloth feed roller group 1 includes a tension adjustment device 14. The cloth 19 can be passed through the tension roller in the tension adjustment device during transportation. The floating of the tension roller can adjust the tension of the cloth 19. The cloth feed roller group 2 includes a tension adjustment device 24. The cloth 29 can be passed through the tension roller in the tension adjustment device during transportation. The floating of the tension roller can adjust the tension of the cloth 29.

[0042] Additionally, feed roller group 1 and feed roller group 2 may be equipped with a width-expanding device and an edge-aligning device. The width-expanding device can expand the fabric to maintain a flat width. The edge-aligning device can align the fabric during transport to prevent deviation and interference between fabric 19 and fabric 29. In this embodiment, both the width-expanding device and the edge-aligning device can employ conventional structures, providing both width-expanding and edge-aligning functions. The edge-aligning device can employ a structure similar to a deviation-correcting roller, capable of adjusting the position of the corresponding fabric, thereby ensuring alignment across the width of the fabric and ensuring accurate positioning during subsequent printing.

[0043] Specifically, the feed roller assembly 1 also includes a width-expanding device 15 and an edge-aligning device 17. The width-expanding device 15 is capable of expanding the width of the fabric 19, while the edge-aligning device 17 is capable of aligning the edges of the fabric 19. The order in which the width-expanding device 15 and the edge-aligning device 17 are installed can be determined based on actual needs. Generally, the edge-aligning device 17 is positioned closer to the printing device 2 so that the edges of the fabric 19 can be aligned before entering the printing device 2.

[0044] Furthermore, a separating roller 16 is installed between the width expansion device 15 and the edge alignment device 17. The effective working width of the separating roller 16 corresponds to the width and position of the cloth 19. As the cloth passes through the separating roller 16, it is separated and expanded in the width direction, achieving a certain width expansion effect and ensuring that the cloth 19 remains flat.

[0045] Specifically, the second feed roller assembly also includes a second widening device 25 and a second edge alignment device 27. The widening device 25 can widen the width of the second fabric 29, and the edge alignment device 27 can align the edges of the second fabric 29. The order in which the widening device 25 and the edge alignment device 27 are installed can be determined based on actual needs. Generally, the edge alignment device 27 should be closer to the printing device 2 so that the second fabric 29 can be aligned before entering the printing device 2.

[0046] Furthermore, a second separator roller 26 is installed between the second expansion device 25 and the second edge alignment device 27. The effective working width of the separator roller 26 corresponds to the width and position of the second cloth 29. As the cloth passes through the separator roller 26, it separates the cloth, expanding it widthwise, achieving a certain width expansion effect and ensuring that the second cloth 29 remains flat.

[0047] In this embodiment, the printing device 2 can be a digital printing device 2, which includes a guide belt 3 and a plurality of printing nozzles. The same printing pattern can be used for the two fabrics, or different printing patterns can be used, which can be specifically set according to the desired printing pattern. The guide belt 3 has an annular structure and can achieve circular rotation. When the fabric 1 19 and the fabric 2 29 are input to the surface of the guide belt 3, the guide belt 3 and the fabric are bonded by the adhesive layer, so that the fabric 1 19 and the fabric 2 29 can be stably and flatly attached to the surface of the guide belt 3. Then, the fabric 1 19 and the fabric 2 29 follow the rotation of the guide belt 3 and pass through the lower side of the printing nozzle. The printing nozzle can print on the fabric 1 19 and the fabric 2 29 at the same time according to the pre-set printing program, realizing double-width feeding and double-width printing, thereby improving the printing efficiency of the fabric.

[0048] Example 2

[0049] This embodiment discloses a double-width cloth-feeding printing device, which is described in detail with reference to Figure 3, building upon the previous embodiment. In this embodiment, cloth 19 and cloth 2 are loaded by cloth loading device 11 and cloth loading device 21, respectively. These loading devices 11 and 21 are located on the side of the cloth feed roller assembly facing away from the printing device 2. To ensure stable cloth transport and prevent deflection during conveyance, a deviation correction device is installed on the side of the traction roller facing away from the printing device 2, ensuring stable cloth transport.

[0050] As shown in Figure 3, the first feed roller assembly also includes a first deflection correction device 110. The first deflection correction device 110 is a deflection correction roller assembly that can adjust the position of the fabric in the width direction and perform deflection correction on the fabric to prevent deflection that affects normal fabric transportation. The second feed roller assembly also includes a second deflection correction device. The second deflection correction device is a deflection correction roller assembly that can adjust the position of the fabric in the width direction and perform deflection correction on the fabric to prevent deflection that affects normal fabric transportation.

[0051] In the cloth feed roller group 1 and the cloth feed roller group 2, the expanding device 15 and the expanding device 2 25 may also share the same expanding device, and only the expanding device 1 15 or the expanding device 2 25 may be provided.

[0052] Example 3

[0053] This embodiment also discloses a dual-width printing method using the dual-width cloth-feeding printing apparatus described in the above embodiment. Referring to FIG4 , cloth 19 is fed to the printing device 2 via the first cloth feed roller assembly, and cloth 2 is fed to the printing device 2 via the second cloth feed roller assembly. Cloth 19 and cloth 2, 29, can be simultaneously fed into the printing device 2 for printing.

[0054] Furthermore, the double-width cloth-feeding printing apparatus of this embodiment further includes a third cloth feed roller set, which forms another cloth conveying route for conveying cloth 3 6. The width of the third cloth feed roller set is greater than the widths of the first and second cloth feed roller sets. The width of the third cloth feed roller set only needs to be less than the width of the running width of the frame 1, thereby enabling the printing apparatus to produce cloth of a larger width.

[0055] Specifically, the cloth feed roller set 3 can share a portion of the guide roller 18 with the cloth feed roller set 1; the cloth feed roller set 3 can share a portion of the guide roller 2 28 with the cloth feed roller set 2, and the cloth 3 6 is conveyed via the guide rollers 18 and 28. Furthermore, the cloth feed roller set 3 can also share the edge alignment device of the cloth feed roller set 1 and the cloth feed roller set 2.

[0056] Furthermore, because the position of cloth (3) 6 during transport differs from that of cloth (1) 19 and cloth (2) 29, the width of cloth (3) 6 is roughly the sum of the widths of cloth (1) 19 and cloth (2) 29. The feed roller assembly (3) is also equipped with an independent width-expanding device (3) 4 and a wire-separating roller (3) 5. These expand the width of cloth (3) 6, thereby maintaining the flatness of cloth (3) 6 during transport.

[0057] 5 , during the printing process, the double-width cloth-feeding printing device can realize double-width cloth feeding and double-width printing of cloth one 19 and cloth two 29, or can realize feeding and printing of either cloth one 19 or cloth two 29 separately, or can realize feeding and printing of cloth three 6 with a larger width separately.

[0058] In addition, in this embodiment, the cloth feed roller group 1 and the cloth feed roller group 2 are arranged side by side, which can realize the simultaneous feeding and printing of two kinds of cloth; or, multiple cloth feed roller groups can be arranged side by side at the same time, which can realize the simultaneous feeding and printing of multiple kinds of cloth.

[0059] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
