Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Two guide belt mechanisms can be arranged in the double-sided printing machine to convey the fabric to be jet-printed, and the front side and the back side of the fabric are respectively jet-printed in the two guide belt mechanisms. In a double-sided printing machine, the surfaces of the two guide belt mechanisms used for jet printing the fabric are generally two substantially parallel planes (e.g., the main bodies of the two guide belt mechanisms are substantially parallel to each other) for printing, and a large separation distance is required between the two parallel planes due to the need for a printing device or the like. At two conduction band mechanism's junction, if the interval distance between two conduction band mechanisms is bigger (for example more than 1 meter apart), can make the fabric of junction be in midair to produce the deformation, the interval distance is big more, and the deflection is also big more, reduces the spout seal precision of fabric, causes harmful effects to product quality.
It should be noted that "splice" is used to indicate a functional connection between two belt guiding mechanisms, and is not limited to direct contact (connection) between two belt guiding mechanisms. In practice, a pre-set region is provided in which the fabric is to be removed from one guide and fed to another, the pre-set region being the "splice" where the two guides are "spliced".
At least one embodiment of the present disclosure provides a double-sided printing machine and a double-sided printing method thereof, which can at least solve the above technical problems. The double-sided printing machine comprises a first guide belt mechanism and a second guide belt mechanism, wherein the first guide belt mechanism and the second guide belt mechanism are configured to be connected at a distance not larger than a preset threshold value so as to convey fabrics to be subjected to jet printing to each other, and enable the fabrics to be turned over in a front-back direction. Because the distance between the first guide belt mechanism and the second guide belt mechanism at the joint is limited by setting the preset threshold, the distance transmitted by the fabric between the first guide belt mechanism and the second guide belt mechanism is small in the process of spraying and printing the fabric by using the double-sided printing machine, so that the deformation of the fabric in the printing process is small, the alignment precision of double-sided printing is improved, the product yield is improved, and the cost is reduced.
For example, in a double-sided printing machine provided in at least one embodiment of the present disclosure, a line connecting a position where the fabric is loaded and unloaded on the first belt guiding mechanism is a first straight line segment, a line connecting a position where the fabric is loaded and unloaded on the second belt guiding mechanism is a second straight line segment, and a distance from an end point of the first straight line segment located at the junction to the second straight line segment is smaller than a distance from another end point of the first straight line segment located outside the junction to the second straight line segment. In this manner, extensions of the first and second linear segments, or both, intersect at or near the junction. Through this scheme, can make to have sufficient space between first conduction band mechanism and the second conduction band structure to set up other devices (for example printing dolly, belt cleaning device etc.), the fabric that can also link up the department can not be unsettled or unsettled size is little to eliminate because of unsettled deformation that causes or reduce the deflection, make the double-sided calico printing machine to the spout of fabric seal the precision height.
For example, in at least one embodiment of the present disclosure, at a junction of the first and second linear segments, the preset threshold is a distance from an end point of the first linear segment at the junction to the second linear segment.
Hereinafter, a double-sided printing machine and a double-sided printing method thereof according to at least one embodiment of the present disclosure will be described with reference to the accompanying drawings.
At least one embodiment of the present disclosure provides a double-sided printing machine including a first guide belt mechanism and a second guide belt mechanism configured to engage at a distance no greater than a preset threshold to convey a fabric to be jet printed to each other and to turn the fabric over on both sides. Illustratively, as shown in FIG. 1A, a double-sided printing machine includes a first belt guide mechanism 100 and a second belt guide mechanism 200. During production, the fabric 1 is loaded into the first belt guide 100 and at the junction (region Q) of the first 100 and second 200 belt guides, the fabric 1 is transported from the first 100 belt guide to the second 200 belt guide. In fig. 1A, the fabric 1 is shown in phantom and moves along a trajectory "→" on the first and second belt guiding mechanisms 100 and 200.
It is noted that in embodiments of the present disclosure, the fabric may be loaded by a first belt guide mechanism and then output to a second belt guide mechanism, or may be loaded by a second belt guide mechanism and then output to the first belt guide mechanism. Illustratively, in a double-sided printing machine as shown in FIG. 3, the web 1 is carried by the second belt guide 200, and at the junction of the first belt guide 100 and the second belt guide 200, the web 1 is transferred from the second belt guide 200 to the first belt guide 100.
In the embodiment of the disclosure, the preset threshold may be set to a fixed value according to the actual process requirement, or may be set according to the thickness of the fabric to be jet-printed. For example, the fixed value may be not more than 1 meter, such as further not more than 50 cm, 40 cm, 30 cm, 20 cm, 10 cm, 5 cm, 2 cm, 1 cm, 0.5 cm, 0.3 cm, 0.2 cm, or 0.1 cm, and the like. For example, the thickness of the fabric to be jet printed may be set to be not more than 30 times the thickness of the fabric, which may be, for example, 25, 20, 15, 10, 5, 2, 1, 0.5, or the like.
For example, in a double-sided printing machine provided in some embodiments of the present disclosure, the preset threshold is set to be no greater than the thickness of the fabric. For example, the ratio of the predetermined threshold to the fabric thickness is about 0.1 to 1, such as further 0.2, 0.4, 0.5, 0.7, or 0.9. In this way, as shown in fig. 1A, the fabric 1 on the first belt guiding mechanism 100 contacts the second belt guiding mechanism 200 after being conveyed to the region Q, so that the automatic conveyance of the fabric 1 between the first belt guiding mechanism 100 and the second belt guiding mechanism 200 is realized, and in the region Q, the fabric 1 does not generate a position deviation in a direction perpendicular to the X axis and the Z axis, so that the fabric 1 is prevented from being deformed in the region Q, and the product yield is high. In such embodiments, the ratio of the predetermined threshold to the fabric thickness may not be limited to the above values.
For example, in some other embodiments of the present disclosure, a preset threshold is set to be greater than the thickness of the fabric. For example, the ratio of the predetermined threshold to the fabric thickness is about 1 to 6, such as further 2, 3, 4, or 5. In this way, as shown in fig. 1A, after the fabric on the first belt guiding mechanism 100 reaches the region Q, the fabric 1 can be transferred to the second belt guiding mechanism 200 by manual operation or an auxiliary device, because the preset threshold is relatively small, the distance for manually moving the fabric 1 is very small, and therefore, the risk of deformation of the fabric 1 at the region Q is small or the amount of deformation is very small, and the product yield is high. In such embodiments, the ratio of the predetermined threshold to the fabric thickness may not be limited to the above values.
Hereinafter, a double-sided printing machine and a double-sided printing method thereof in at least one embodiment of the present disclosure described below will be described by taking as an example that a preset threshold is set not greater than the thickness of a fabric.
For example, in a double-sided printing machine provided in at least one embodiment of the present disclosure, the first guide belt mechanism includes at least two first guide belt rollers configured to support the first guide belt to form a first surface having a role of a printing platform; and the second guide belt mechanism comprises at least two second guide belt rollers and a second guide belt, the second guide belt rollers being configured to support the second guide belt to form a second surface and a third surface having a print platform role; wherein the second surface is engaged with a surface of the first conduction band.
Illustratively, as shown in fig. 1A, the first tape guide rollers 101 and 102 support a first tape guide 110, a surface of the first tape guide 110 located between the first tape guide rollers 101 and 102 and facing away from the first tape guide rollers is a first surface 111, a first printing region 11 is provided between the first tape guide rollers 101 and 102, and a portion of the first surface 111 located in the first printing region 11 serves as a printing platform. The second guide rollers 201 and 202 support a second guide belt 210, the surface of the second guide belt 210 between the second guide rollers 201 and 202 facing the first guide belt mechanism 100 being a second surface 211, the second surface 211 being for carrying the fabric 1, a second printing area 12 being provided between the second guide rollers 201 and 202, the portion of the second surface 211 located in the second printing area 12 serving as a printing platform. The portion of the outer surface of the second conduction band 210 that is not used to carry the fabric 1, between the second conduction band rollers 201 and 202, is a third surface 212. The second surface 211 is engaged with the surface of the first belt 110, so that, during production, the fabric 1 is first carried by the first belt 110 into the first belt mechanism 100, the surface of the fabric 1 facing away from the first belt 110 is assumed to be the front surface, the fabric 1 is brought into contact with the second belt 210 after being conveyed by the first belt 110 into the region Q, and then the fabric 1 is conveyed by the second belt 210 into the second belt mechanism 200, in which case the fabric 1 is turned over, i.e. the surface of the fabric 1 facing away from the second belt 210 is the back surface, during which process it is possible to carry out jet printing on the front surface and the back surface of the fabric 1, respectively.
It should be noted that, in the embodiments of the present disclosure, the first tape guide roller and the second tape guide roller may include a driving roller, a supporting roller, a guiding roller, or other types of rollers. The drive roller may be connected to a drive means (e.g. a motor) to drive the belt in movement. The supporting roller is used for supporting the conduction band, can be arranged in a rolling mode or other types, and the guide roller can be arranged at the inflection point of the conduction band or the fabric so as to adjust the motion track of the conduction band or the fabric. For example, in the first belt guiding mechanism, the plurality of first belt guiding rollers include at least one driving roller, may further include a supporting roller, and further may include a guiding roller. Illustratively, in the first tape guide roller of fig. 1A, 104 is a guide roller, and one of 101 and 102 is a drive roller and the other is a support roller.
For example, in a double-sided printing machine provided in at least one embodiment of the present disclosure, a line connecting a position where the fabric is loaded and unloaded on the first belt guiding mechanism is a first straight line segment, a line connecting a position where the fabric is loaded and unloaded on the second belt guiding mechanism is a second straight line segment, and a distance from an end point of the first straight line segment located at the junction to the second straight line segment is smaller than a distance from another end point of the first straight line segment located outside the junction to the second straight line segment. Illustratively, as shown in fig. 1B, after the fabric 1 is loaded onto the first belt 110, it is pulled off the first belt 110 at the splice Q and onto the second belt 210, and finally pulled off the second belt 210. The line connecting the position where the fabric 1 is carried on the first belt 110 and exits at the splice Q is a first straight line segment (shown as its extension L1), and the line connecting the position where the fabric 1 is carried on the second belt 210 at the splice Q and finally exits the second belt 210 is a second straight line segment (shown as its extension L2). Because one end point of the first straight line segment at the junction Q is closer to the second straight line segment than the other end point of the first straight line segment is to the second straight line segment, the first straight line segment and the second straight line segment are closer at the junction Q, so that the extension lines of the first straight line segment and the second straight line segment intersect to define an included angle C. In this way, while the preset threshold of the joint Q is ensured, there is enough space in the region corresponding to the included angle C with the first straight line segment and the second straight line segment as the boundary for arranging other devices (e.g., the first cleaning device 401, the second printing cart 20, etc. in fig. 1A).
It should be noted that the smaller the distance from the end point of the first straight line segment located at the joint to the second straight line segment is, the closer the vertex of the included angle between the first straight line segment and the second straight line segment is to the joint, and correspondingly, the smaller the preset threshold value at the joint is, the smaller the suspended size of the fabric at the joint is, so that the smaller the deformation amount of the fabric is, the higher the spray printing precision of the double-sided printing machine on the fabric is. For example, as shown in fig. 1B, when the preset threshold is equal to the thickness of the fabric 1, the vertex of the included angle C is located at the joint Q, and the distance from the end point of the first straight line segment located at the joint Q to the second straight line segment is the thickness of the fabric 1, that is, the fabric 1 is not suspended at the joint Q, so that there is no deformation caused by suspension, and the spray printing precision of the double-sided printing machine on the fabric is high.
For example, in a double-sided printing machine provided in at least one embodiment of the present disclosure, the first belt guide mechanism further includes a first belt guide glue layer on a surface of the first belt guide, the first belt guide glue layer covering the first surface; and the second conduction band mechanism also comprises a second conduction band glue layer positioned on the surface of the second conduction band, and the second conduction band glue layer covers the second surface and the third surface. For example, in some embodiments of the present disclosure, the viscosity of the second conductive tape glue layer and the first conductive tape glue layer are not equal. Illustratively, as shown in fig. 1A, 2A and 2B, a first layer of conductive tape 120 is applied to a surface of the first conductive tape 110 facing away from the first tape guide roller for adhering the fabric 1, and a second layer of conductive tape 220 is applied to a surface of the second conductive tape 210 facing away from the second tape guide roller for adhering the fabric 1. For example, in fig. 1A, the viscosity of the first belt rubber layer 120 is lower than that of the second belt rubber layer 220, so that the fabric 1 is separated from the first belt rubber layer 120 after reaching the region Q and being bonded to the second belt rubber layer 220, thereby realizing the transfer of the fabric 1 from the first belt guide 100 to the second belt guide 200.
It should be noted that, in other embodiments of the present disclosure, the viscosities of the second conductive tape layer and the first conductive tape layer may be approximately equal. In this case, the transfer of the fabric between the two belt guiding mechanisms may be accomplished by manual operation, by the provision of auxiliary equipment, or the like.
For example, in a double-sided printing machine provided in at least one embodiment of the present disclosure, the first belt guiding mechanism includes at least three first belt guiding rollers, a first and a second of the at least three first belt guiding rollers are located on a first horizontal plane to support the first belt to form a first surface, a third and a first of the at least three first belt guiding rollers are located on a plane perpendicular or inclined to the first horizontal plane to support the first belt to form a fourth surface, and the first surface and the fourth surface are connected.
In one example, as shown in FIG. 1A, first through third first tape guide rollers are labeled 101, 102, and 103 in that order, the first tape guide rollers 101 and 102 are positioned in a plane parallel to the X-axis, the first tape guide rollers 101 and 102 support the first tape guide 110 to form a first surface 111, the first tape guide rollers 101 and 103 are positioned in a plane parallel to the Z-axis, the first tape guide rollers 101 and 103 support the first tape guide 110 to form a fourth surface 112, and the first surface 111 is connected to the fourth surface 112. For example, the fourth surface 112 is engaged with the second surface 211.
In another example, as shown in fig. 4, first to third first tape guide rollers are sequentially designated as 101, 102 and 103, the first tape guide rollers 101 and 102 are positioned on a plane parallel to the X-axis, the first tape guide rollers 101 and 102 support the first tape guide 110 to form a first surface 111, the first tape guide rollers 101 and 103 are positioned on a plane intersecting both the Z-axis and the X-axis, the first tape guide rollers 101 and 103 support the first tape guide 110 to form a fourth surface 112, and the first surface 111 is connected to the fourth surface 112. For example, the fourth surface 112 is engaged with the second surface 211. In this example, the gravitational force generated by the portion of the fabric 1 located at the fourth surface 112 during the transport of the fabric 1 by the first conduction band 110 may be shared by the first conduction band 110, thereby reducing the risk of the portion of the fabric 1 escaping from the first conduction band 110. For example, the Z-axis is parallel to the direction of gravity.
For example, in some embodiments of the present disclosure, a first surface of a first conduction band and a second surface of a second conduction band are joined. Illustratively, as shown in fig. 5, the first belt guiding mechanism 100 includes a plurality of first belt guiding rollers, the first belt guiding rollers 101 and 102 support the first belt 110 to form the first surface 111, the first belt guiding roller 101 has a larger diameter than the other first belt guiding rollers, and the first belt guiding roller 101 is located at the junction of the first belt guiding mechanism 100 and the second belt guiding mechanism 200 so that the first surface 111 and the second surface 211 are joined.
For example, in some embodiments of the present disclosure, a double-sided printing machine is provided, wherein the first guide belt mechanism includes at least four first guide belt rollers, and a fourth of the at least four first guide belt rollers is located between the second and third guide belt rollers to change a path of the first guide belt. Illustratively, as shown in fig. 1A, 3 and 4, the first belt guiding mechanism 100 includes four first belt guiding rollers, and the first to fourth first belt guiding rollers are designated 101, 102, 103 and 104 in this order. The first to third first tape guide rollers may be arranged in a manner as described in relation to the previous embodiment, with the fourth first tape guide roller 104 being located between the second first tape guide roller 102 and the third first tape guide roller 103.
For example, in other embodiments of the present disclosure, as shown in fig. 5, where the first surface 111 of the first belt 110 is engaged with the second surface 211 of the second belt 210, the first belt guide mechanism 100 includes at least three first belt guide rollers, a first 101 and a second 102 of the at least three first belt guide rollers being configured to support the first belt 110 to form the first surface 111, the first 101 being located at the engagement of the first belt guide mechanism 100 and the second belt guide mechanism 200 to engage the first surface 111 with the second surface 211, and the third 103 being located between the first 101 and the second 102 to alter the path of the first belt 110.
For example, at least one embodiment of the present disclosure provides a double-sided printing machine further comprising a first printing carriage and a second printing carriage. The first printing carriage is configured to be opposite to a first surface on the first belt guiding mechanism to jet print one of the obverse and reverse surfaces of the fabric, and the second printing carriage is configured to be opposite to a second surface on the second belt guiding mechanism to jet print the other of the obverse and reverse surfaces of the fabric. Illustratively, as shown in FIG. 1A, a first print carriage 10 is provided at a first print zone 11 and a second print carriage 20 is provided at a second print zone 12. Thus, when the fabric 1 is loaded on the first conduction band 110 and enters the first printing area 11, the surface of the fabric 1 facing away from the first conduction band 110 is the front (or back), the front (or back) of the fabric 1 is jet printed by the first printing cart 10, when the fabric 1 is transferred from the first conduction band 110 to the second conduction band 210, the fabric 1 is turned over, that is, on the second conduction band 210, the surface of the fabric 1 facing away from the second conduction band 210 is the back (or front), and when the fabric 1 enters the second printing area 12, the back (or front) of the fabric 1 is jet printed by the second printing cart 20, so that double-sided printing of the fabric 1 can be achieved.
For example, in an embodiment of the present disclosure, the first and second printing carriages may be mounted on an inkjet printing rail beam fixed to the frame and may reciprocate on the inkjet printing rail beam to inkjet print the obverse or reverse side of the fabric.
For example, in the embodiments of the present disclosure, the jet printing ink used in jet printing may include reactive dye ink, acid dye ink, disperse dye ink, or water-based paint ink, and the like, and the fabric includes silk, cotton cloth, wool, cashmere, or chemical fiber, and the like.
It should be noted that, in the embodiments of the present disclosure, the inkjet printing may be a high and new technology product integrating mechanical, computer and electronic information technologies, which is gradually formed along with the continuous development of computer technology, and is a printing method in which, under the control of a computer, ink containing a colorant is ejected onto a substrate to be printed through a nozzle according to design requirements, and then, after appropriate treatment, a pattern with certain fastness and vividness is formed. The jet printing ink may include, but is not limited to, reactive dye inks, acid dye inks, disperse dye inks, or aqueous paint inks, among others.
For example, at least one embodiment of the present disclosure provides a double-sided printing machine further including a first washing device and a second washing device. The first cleaning device is configured to be opposite to a portion of an outer surface of the first belt detached from the fabric to clean the first belt, for example, the first cleaning device is configured to be opposite to a surface of the first belt other than the first surface and the fourth surface to clean the first belt. The second cleaning device is configured to be opposite to a third surface of the second conduction band to clean the second conduction band. Illustratively, as shown in FIG. 1A, two first belt guide rollers 102 and 104 support the first belt 110 to form a fifth surface 113, a first cleaning device 401 is disposed opposite the fifth surface 113, and a second cleaning device 402 is disposed opposite the third surface 212. In this way, the parts of the first and second belts 110 and 210 separated from the fabric 1 are respectively cleaned by the first and second cleaning devices 401 and 402, so that the fabric is prevented from being polluted by residues of the fabric or other pollutants, thereby improving the product yield.
For example, at least one embodiment of the present disclosure provides that the double-sided printing machine further comprises an alignment device configured to acquire a specific position of the fabric and/or a pattern shape on the fabric. The aligning device is positioned between the first printing trolley and the second printing trolley along the moving track of the fabric on the first guide belt and the second guide belt. Illustratively, as shown in fig. 1A, along the moving track of the fabric 1, the first printing carriage 10, the aligning device 300 and the second printing carriage 20 are arranged in sequence, for example, the aligning device 300 is located between the region Q and the second printing carriage 20. In this way, the fabric 1 is first captured by the alignment device 300 to obtain a specific position and/or pattern shape on the fabric before being jet-printed by the second printing cart 20, so that the second printing cart 20 can be adjusted and controlled accordingly.
For example, in a double-sided printing machine provided by some embodiments of the present disclosure, in a case where the alignment device is located between the first printing carriage and the second printing carriage, the alignment device and the two printing carriages are arranged at an interval. For example, the aligning device is close to the next printing trolley along the moving track of the fabric.
For example, in other embodiments of the disclosure, a double-sided printing machine is provided, in which the aligning device is mounted on one of the printing carriages with the aligning device located between the first printing carriage and the second printing carriage. For example, the aligning device is arranged on the subsequent printing trolley along the moving track of the fabric. Illustratively, as shown in fig. 1A, the alignment device 300 is mounted on the second print carriage 20.
For example, the alignment device may be a camera or a laser positioning device. Illustratively, as shown in fig. 1A, the alignment device 300 is a camera, and before the fabric 1 is jet-printed by using the second printing cart 20, the camera is used to photograph a specific position of the fabric (e.g., a relative position to the second guiding belt 210) and/or a pattern shape on the fabric, so as to determine whether the fabric 1 is shifted or deformed, and then adjust and control a position of the second printing cart 20, so as to improve the accuracy of the jet-printing.
For example, in a double-sided printing machine provided in at least one embodiment of the present disclosure, the fabric is a whole roll of fabric, and the double-sided printing machine further includes a cloth receiving roller and a cloth releasing roller. The cloth receiving roller is configured to drive the whole roll of fabric to step by one of the first guiding mechanism and the second guiding mechanism, and the cloth releasing roller is configured to drive the whole roll of fabric to be recovered from the other of the first guiding mechanism and the second guiding mechanism. Illustratively, as shown in fig. 1A, a feed roll 510 is located at the inlet of the double-side printing machine for providing the web 1 for transport into the first belt guide 100, and a take-up roll 520 is located at the outlet of the double-side printing machine for recovery by the take-up roll 520 after the web 1 has been subjected to the double-side printing process and is transported out of the second belt guide 200.
For example, in a double-sided printing machine provided in at least one embodiment of the present disclosure, as shown in fig. 1A, the double-sided printing machine includes a first cloth guide roller 410 and a second cloth guide roller 420, the first cloth guide roller 410 is used for guiding the fabric 1 on the cloth placing roller 510 into the first belt guiding mechanism 100 at a proper angle, and the second cloth guide roller 420 is used for guiding the fabric 1 in the second belt guiding mechanism 200 out to the cloth collecting roller 520.
For example, in at least one embodiment of the present disclosure, the double-sided printing machine may further include a cloth press roller. Illustratively, as shown in fig. 1A, a cloth press roll 610 may press the web 1 against the first surface 111 of the first conduction band 110. Note that the number of the cloth pressing rollers is not limited, and the positions are set as needed, and are not limited to the positions shown in fig. 1A.
For example, in the double-sided printing machine provided by at least one embodiment of the present disclosure, the fabric is a cut fabric, and the double-sided printing machine further includes a material placing frame and a material receiving frame. The feeding frame is configured to place the cut piece fabric on one of the first belt guiding mechanism and the second belt guiding mechanism. The collecting frame is configured to recycle the other of the first belt guiding mechanism and the second belt guiding mechanism of the cut piece fabric. For example, as shown in fig. 6, the double-sided printing machine includes a material placing frame 710 and a material receiving frame 720, the material placing frame 710 is used for placing the fabric 1 to be double-sided printed, the material receiving frame 720 is used for placing the fabric 1 with double-sided printed, and other structures in fig. 6 may refer to the relevant description of the embodiment shown in fig. 1A, and are not described herein again.
For example, the double-sided printing machine provided by at least one embodiment of the present disclosure may further include at least one drying device. For example, the fabric, the first conduction band or the second conduction band may be dried after the fabric is subjected to spray printing and the first conduction band or the second conduction band is washed with water. For example, the drying temperature is between 100 ℃ and 120 ℃, for example, further 105 ℃, 110 ℃, 115 ℃ or the like; the drying time is between 5 minutes and 10 minutes, for example, further 6, 7, 8, or 9 minutes, and the like.
For example, in at least one embodiment of the present disclosure, the dried fabric may be steamed and/or washed with water. For example, after the fabric is dried by the drying device, the fabric may be steamed; and further, washing the steamed fabric with water to remove the loose color and the auxiliary agent on the surface of the fabric. Here, the vaporization temperature is generally between 100 ℃ and 105 ℃, for example, further 101 ℃, 102 ℃, 103 ℃ or 104 ℃ and the like; the steaming time is generally between 10 minutes and 15 minutes, for example, further 11, 12, 13 or 14 minutes, and the like. For example, the water washing may be performed by washing with cold water at 20 to 26 ℃ for 4 to 8 minutes and then with hot water at 40 to 50 ℃ for 3 to 4 minutes.
At least one embodiment of the present disclosure provides a double-sided printing method of a double-sided printing machine including a first guide belt mechanism and a second guide belt mechanism configured to engage at a distance not greater than a preset threshold to convey a fabric to be jet-printed to each other and to turn the fabric over on both sides, the method including: and driving one of the first and second guiding mechanisms to load the fabric, and conveying the fabric into the other of the first and second guiding mechanisms at the junction of the first and second guiding mechanisms, thereby realizing the reversible turning of the fabric between the first and second guiding mechanisms. Because the distance between the first guide belt mechanism and the second guide belt mechanism is limited by setting the preset threshold, the distance transmitted by the fabric between the first guide belt mechanism and the second guide belt mechanism is reduced in the process of spraying and printing the fabric by using the double-sided printing machine, so that the deformation of the fabric in the printing process is reduced, the alignment precision of double-sided printing is improved, the product yield is improved, and the cost is reduced. In the double-sided printing method, the structure of the double-sided printing machine and the process of spraying and printing the fabric can refer to the related descriptions in the foregoing embodiments (for example, the embodiments shown in fig. 1A, fig. 2B, and fig. 3-fig. 5), and are not described herein again.
For example, in a double-sided printing method of a double-sided printing machine provided in at least one embodiment of the present disclosure, the structure of the double-sided printing machine is: the connecting line of the positions where the fabric is loaded and separated on the first guide belt mechanism is a first straight line section, the connecting line of the positions where the fabric is loaded and separated on the second guide belt mechanism is a second straight line section, and the distance from the end point of the first straight line section, which is positioned at the joint, to the second straight line section is smaller than the distance from the other end point of the first straight line section, which is positioned outside the joint, to the second straight line section. For example, at the junction of the first and second belt guiding mechanisms, the preset threshold is the distance from the end point of the first straight line segment at the junction to the second straight line segment.
For example, in a double-sided printing method provided in at least one embodiment of the present disclosure, the first guide belt mechanism includes a first guide belt coated with a first guide belt glue layer for adhering to the fabric, the second guide belt mechanism includes a second guide belt coated with a second guide belt glue layer for adhering to the fabric. Under the condition that the viscosity of the first conduction band glue layer is smaller than that of the second conduction band, the first conduction band is loaded into the fabric, and the fabric is separated from the first conduction band and loaded onto the second conduction band by using the second conduction band glue layer at the joint of the first conduction band mechanism and the second conduction band mechanism; or in the case that the viscosity of the first conduction band glue layer is larger than that of the second conduction band, the second conduction band is loaded into the fabric, and the fabric is separated from the second conduction band and loaded onto the first conduction band by using the first conduction band glue layer at the joint of the first conduction band mechanism and the second conduction band mechanism. Therefore, the fabric is fixed by the adhesive way through the tape guide glue layer, and the fabric can be separated from the tape guide glue layer conveniently while being convenient to load and convey the fabric, so that the damage to the fabric is reduced. In the double-sided printing method, the structure of the double-sided printing machine and the process of spraying and printing the fabric can refer to the related descriptions in the foregoing embodiments (for example, the embodiments shown in fig. 1A, fig. 2A and fig. 2B), and details are not described herein.
For example, in a double-sided printing method provided in at least one embodiment of the present disclosure, the preset threshold is set to be not greater than a thickness of the fabric, and the feeding of the fabric to the other of the first and second belt guiding mechanisms includes: when the fabric is conveyed to the joint of the first guide belt mechanism and the second guide belt mechanism, the fabric is automatically contacted with the first guide belt glue layer or the second guide belt glue layer on the other one of the first guide belt mechanism and the second guide belt mechanism, so that the front and back of the fabric between the first guide belt mechanism and the second guide belt mechanism are turned over. Therefore, the automatic transmission of the fabric between the first guide belt mechanism and the second guide belt mechanism can be realized, the fabric cannot generate position deviation in the process, the fabric is prevented from being deformed, and the product yield is high. In the double-sided printing method, the structure of the double-sided printing machine and the process of spraying and printing the fabric can refer to the related descriptions in the foregoing embodiments (for example, the embodiments shown in fig. 1A, fig. 2B, and fig. 3-fig. 5), and are not described herein again.

Therefore, the preset threshold is smaller, the distance for manually moving the fabric is very small, the risk of deformation of the fabric is small or the deformation amount is very small in the process of conveying the fabric between the first guide belt mechanism and the second guide belt mechanism, and the product yield is high. In the double-sided printing method, the structure of the double-sided printing machine and the process of spraying and printing the fabric can refer to the related descriptions in the foregoing embodiments (for example, the embodiments shown in fig. 1A, fig. 2B, and fig. 3-fig. 5), and are not described herein again.
For example, in a double-sided printing method provided in at least one embodiment of the present disclosure, the double-sided printing machine further includes a first printing carriage and a second printing carriage, and the method further includes: carrying out jet printing on one of the front surface and the back surface of the fabric positioned on the first conduction band by using a first printing trolley; and spraying and printing the other of the front surface and the back surface of the fabric on the second conduction band by using a second printing trolley. In this way, double-sided printing of the fabric can be achieved. In the double-sided printing method, the structure of the double-sided printing machine and the process of spraying and printing the fabric can refer to the related descriptions in the foregoing embodiments (for example, the embodiments shown in fig. 1A, fig. 2B, and fig. 3-fig. 5), and are not described herein again.
For example, in a double-sided printing method provided by at least one embodiment of the present disclosure, the double-sided printing machine further includes an alignment device for acquiring a specific position of the fabric and/or a pattern shape on the fabric, the alignment device is located between the first printing carriage and the second printing carriage along a moving track of the fabric on the first guiding belt and the second guiding belt, and the double-sided printing method further includes: after one pair of fabrics of the first printing trolley and the second printing trolley is used for spray printing, the position of the fabrics is confirmed through the aligning device, and then the other pair of fabrics of the first printing trolley and the second printing trolley is used for spray printing. For example, the alignment device is a camera. In this way, the specific position (for example, the relative position with the second conduction band) of the fabric and/or the pattern shape on the fabric are shot by using the camera, so that whether the fabric deviates or deforms is determined, and then the position of the second printing trolley is regulated, so that the jet printing accuracy is improved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and the like that are within the spirit and principle of the present invention are included in the present invention.
