Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of textile performance testing, in particular to a textile printing fastness testing device. Background Art
[0002] Textiles are often printed on, and print fastness refers to the durability of the print pigment on the fabric, which prevents it from fading, breaking, or falling off during washing. By testing print fastness, the degree of fixation and durability of the print pigment can be assessed, providing reliable data support for textile printing processing. Currently, most tests for print fastness use a washing, drying, and inspection test method. During the washing process, the impact of water flow on the print exerts an external force on the print, causing the print to fall off. The textile is then dried, and the print is inspected for shedding, thereby evaluating the print fastness. This method has a complex operating process, a long testing cycle, and low testing efficiency. For prints with a large area, the prints may fold over each other during the washing process, causing the impact force of the water flow to act on a local part of the print, resulting in lower accuracy in the test results.

[0030] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.
[0031] Textiles are often printed on, and print fastness refers to the durability of the print pigment on the fabric, which prevents it from fading, breaking, or falling off during washing. By testing print fastness, the degree of fixation and durability of the print pigment can be assessed, providing reliable data support for textile printing processing. Currently, most tests for print fastness use a washing, drying, and inspection test method. During the washing process, the impact of water flow on the print exerts an external force on the print, causing the print to fall off. The textile is then dried, and the print is inspected for shedding, thereby evaluating the print fastness. This method has a complex operating process, a long testing cycle, and low testing efficiency. For prints with a large area, the prints may fold over each other during the washing process, causing the impact force of the water flow to act on a local part of the print, resulting in lower accuracy in the test results.
[0032] In order to solve the above problems, the utility model provides a textile printing fastness testing device for testing the fastness of printing, which simplifies the testing process, shortens the testing cycle, and improves the testing efficiency and test accuracy.
[0033] Example 1
[0034] See also Figures 1 to 3 The textile print fastness testing device includes a roller 1 and a connecting assembly 2. The roller 1 is cylindrical and extends along a first axis. The outer surface of the roller 1 is used for roller printing. The connecting assembly 2 includes a first connecting member 21 and a second connecting member 22. The first connecting member 21 is rotatably connected to the roller 1 and can rotate relative to the first connecting member 21 about the first axis. The second connecting member 22 is disposed on one side of the roller 1 and is detachably connected to the first connecting member 21.
[0035] During use, an adhesive layer is laid on the outer surface of the rolling member 1, and the second connecting member 22 is held to push the rolling member 1 to rotate relative to the first connecting member 21 about the first axis, so that the rolling member 1 rolls the print. During the rolling process of the rolling member 1, the adhesive layer repeatedly adheres to and detaches from the print. During the process of detaching from the print, the adhesive layer pulls the print away from the fabric, thereby observing the shedding of the print and evaluating the firmness of the print, simplifying the test process, shortening the test cycle, and improving test efficiency. The operator holds the second connecting member 22 to push the rolling member 1, which can ensure that the rolling member 1 rolls on the printed area, improving test accuracy.
[0036] The roller 1 is cylindrical and conveniently rolls over the printed surface. A first connector 21 is rotatably connected to the roller 1, enabling it to rotate relative to the first connector 21 about a first axis, thereby rolling over the printed surface. A second connector 22 is positioned on one side of the roller 1 to prevent interference with its rotation and facilitate gripping by the operator. The first and second connectors 21, 22 are detachably connected, facilitating assembly and storage.
[0037] See also Figure 1 In this embodiment, the first connecting member 21 is inserted into the rolling member 1 along the first axial direction, and both ends of the first connecting member 21 protrude from the rolling member 1. The second connecting member 22 includes two support arms 221 and a connecting arm 222 arranged between the two support arms 221. Each end of the first connecting member 21 is connected to a support arm 221.
[0038] The first connecting member 21 extends through the rolling member 1 along the first axis, ensuring that the rolling member 1 can rotate relative to the first connecting member 21 about the first axis. The first connecting member 21 protrudes from both ends of the rolling member 1 and connects to support arms 221. The two support arms 221 are fixedly connected to connecting arms 222, securing the second connecting member 22 to the first connecting member 21. The first connecting member 21 is rotatably connected to the rolling member 1, allowing the operator to grasp the connecting arms 222 to roll the rolling member 1 across the printing area.
[0039] The rotational connection between the first connecting member 21 and the rolling member 1 can be a clearance connection or a bearing connection, as long as the rolling member 1 can rotate about the first axis relative to the first connecting member 21. The first connecting member 21 is rod-shaped, and the rolling member 1 is provided with a mounting through-hole. The mounting through-hole passes through the rolling member 1 along the first axis. The first connecting member 21 is inserted into the mounting through-hole, and the outer surface of the first connecting member 21 and the inner wall of the mounting through-hole are clearance-fitted, so that the rolling member 1 can rotate about the first connecting member 21.
[0040] The second connecting member 22 can be a whole or a split structure. In this embodiment, the second connecting member 22 is an integrally formed structure. Specifically, the second connecting member 22 is a U-shaped structure, and the support arm 221 and the connecting arm 222 are integrally formed, which is simple to process and easy to manufacture.
[0041] The second connecting member 22 is detachably connected to the first connecting member 21, which is convenient for replacing the rolling member 1, changing the length of the rolling member 1, ensuring that the rolling member 1 rolls on the print, and improving the accuracy of the test. In this embodiment, the first connecting member 21 and the second connecting member 22 are connected by existing nuts, which are firmly connected and easy to assemble and disassemble. The first connecting member 21 is passed through the rolling member 1 along the first axial direction and protrudes from the two ends of the rolling member 1. The protruding part is provided with a thread. The support arm 221 is plate-shaped, and the support arm 221 is provided with a through hole for passing the first connecting member 21. For the convenience of description, the two support arms 21 are respectively the first support arm and the second support arm. The first connecting member 21 is provided with four nuts 23, two of which are provided on both sides of the first support arm. After tightening, the first support arm can be fixed. The other two nuts 23 are provided on both sides of the second support arm. After tightening, the second support arm can be fixed.
[0042] When testing the print's fastness, rollers 11 of varying mass are used to ensure accuracy. Rollers 1 of varying mass exert varying pressures on the adhesive layer, and thus, varying pulling forces on the print. Rollers 1 of varying mass can be easily replaced. Specifically, remove the nut 23 from the first connector 21, separate the first connector 21, roller 1, and second connector 22, and then select a roller 1 of appropriate mass and connect it to the first connector 21 using the nut.
[0043] The mass of the current rolling element 1 can also be changed without replacing it. In this embodiment, the rolling element 1 is provided with a housing chamber, which contains a counterweight. By placing the counterweight in the housing chamber, the mass of the rolling element 1 can be changed, improving the accuracy of the test results. The housing chamber can be spherical or cylindrical, depending on the design requirements. To change the mass of the rolling element 1, the mass of the counterweight can be increased or decreased.
[0044] Illustratively, one end of the rolling element 1 is provided with an opening communicating with the accommodating cavity, and a cover is provided at the opening. By opening the cover, the counterweight can be replaced. Illustratively, the rolling element 1 includes a first body 11 and a second body 12, which interlock to form the accommodating cavity. The first body 11 and the second body 12 are detachably connected. The detachable connection design facilitates the placement of the counterweight within the accommodating cavity. Optionally, at least one of the first body 11 and the second body 12 is hollow.
[0045] The detachable connection between the first body 11 and the second body 12 can be a clamping connection or a threaded connection. Referring to Figure 3 , for example, the first body 11 is threadedly connected with the second body 12. The first body 11 includes a protruding portion, the outer surface of the protruding portion is provided with threads, and the inner side of the second body 12 is provided with threads, so that the protruding portion can be threadedly connected with the second body 12. The outer diameters of the first body 11 and the second body 12 are the same, so that the outer surface of the rolling element 1 can be uniformly stressed during the rolling and printing of the rolling element 1, thereby improving the test results.
[0046] In the present embodiment, the counterweight is a ball, and the counterweight can roll inside the accommodating cavity. When the rolling element 1 rolls on the print, the counterweight is always at the bottom of the rolling element 1 due to the action of gravity, continuously applying pressure to the adhesive layer, thereby ensuring the accuracy of the test results. The counterweight can be one or more, as long as it can roll inside the accommodating cavity, and the present embodiment does not specifically limit the number of counterweights.
[0047] Referring to Figure 1 and Figure 2 , in order to more conveniently roll the rolling element 1, the textile print fastness testing device further includes a holding element 3, which is arranged on the side of the second connecting element 22 away from the rolling element 1, and extends in a direction perpendicular to the first axis and is fixedly connected with the second connecting element 22.
[0048] The holding element 3 and the second connecting element 22 can be connected by existing bolts, which is reliable and convenient to disassemble. The operator can hold the holding element 3 and press it downward to make the rolling element 1 roll on the print, thereby reducing the labor intensity of the operator. The outer surface of the holding element 3 can also be sleeved with a buffer element for improving the holding comfort. The buffer element can be made of existing rubber, which is easy to obtain and convenient to process.
[0049] Embodiment Two
[0050] Figure 4 Embodiment Two is shown, wherein the same or corresponding parts as in Embodiment One are denoted by the same reference numerals. For the sake of simplicity, only the differences between Embodiment Two and Embodiment One are described. The difference lies in that the connecting arm 222 is detachably connected with the supporting arm 221, and the spacing between the two supporting arms 221 is adjustable. The detachable connection between the connecting arm 222 and the supporting arm 221 can be a threaded connection or a clamping connection. Referring to
[0051] Figure 4 , the connecting arm 222 and the support arm 221 are connected by nuts to achieve detachable connection. The support arm 221 is plate-shaped, and through holes are provided at both ends of the support arm 221. For the convenience of description, the two through holes are respectively a first through hole and a second through hole. The connecting arm 222 is passed through the first through hole, and the first connecting member 21 is provided in the second through hole. The connecting arm 222 can be a threaded rod or at least partially provided with threads at both ends. Four nuts 23 are sleeved on the connecting arm 222. Two of the nuts 23 are provided on both sides of the first through hole of one support arm 221, and the other two nuts 23 are provided on both sides of the first through hole of the other support arm 221. By loosening or tightening the nuts 23, the connecting arm 222 and the support arm 221 can be disassembled or installed.
[0052] The first connecting member 21 is rod-shaped and extends through the rolling member 1 along the first axis. The first connecting member 21 and the rolling member 1 are loosely fitted, ensuring that the rolling member 1 can roll around the first connecting member 21 and facilitating separation of the rolling member 1 and the first connecting member 21. Both ends of the first connecting member 21 protrude from both sides of the rolling member 1, facilitating a fixed connection between the first connecting member 21 and the second connecting member 22.
[0053] The first connector 21 and the second connector 22 can be connected using nuts or a snap-on connection. The nuts connect the first connector 21 and the second connector 22, achieving detachable connection. The first connector 21 has threads at both ends, and four nuts 23 are sleeved on the first connector 21. Two nuts 23 are positioned on either side of the second through-hole of one support arm 221, and the other two nuts 23 are positioned on either side of the second through-hole of the other support arm 221. The first connector 21 and the support arm 221 can be removed or installed by loosening or tightening the nuts 23.
[0054] The first connecting member 21 can be mounted with one or more rollers 1. To accommodate prints of varying sizes, the spacing between the two support arms 221 can be adjusted, and rollers 1 of varying lengths can be replaced. Alternatively, the number of rollers 1 can be varied to adjust their length, improving test accuracy.
[0055] When a rolling member 1 is mounted on the first connecting member 21, to replace the rolling member 1, it is necessary to loosen the nut 23 on the side of one of the support arms 221 away from the rolling member 1, remove the support arm 221 and the nut 23 from the first connecting member 21 and the connecting arm 222, then remove the nut 23 on the side close to the rolling member 1, and then replace the rolling member 1 of a suitable length, install the nut 23 and the support arm 221, tighten the nut 23 to clamp the support arm 221, so that the support arm 221 and the first connecting member 21 and the connecting arm 222 are fixed, and the rolling member 1 can roll around the first connecting member 21. The operator holds the connecting arm 222 and pushes the rolling member 1 to roll in the printing area.
[0056] When multiple rolling members 1 are mounted on the first connecting member 21, the length of the rolling members 1 can be changed by splicing them together. Specifically, one end face of the rolling member 1 has a groove, and the other end face has a protrusion. The protrusion is inserted into the groove, so that the two rolling members 1 are fixed together, and the length of the rolling member 1 is changed. When in use, first remove the support arm 221 located on one side of the groove, and then insert the protrusion of another rolling member 1 into the groove to increase the rolling length of the rolling member 1. After the two rolling members 1 are spliced together, install the connecting arm 222 on one side of the groove of the rolling member 1 and fix it with a nut 23, so that the first connecting member 21 and the second connecting member 22 are fixed together. The operator holds the connecting arm 222 and pushes it downward at an angle to make the rolling member 1 rotate around the first connecting member 21 and roll on the printing surface.
[0057] Example 3
[0058] Figure 5 A third embodiment is shown, wherein components identical or corresponding to those in the first embodiment are denoted by corresponding reference numerals. For simplicity, only the differences between the third embodiment and the first embodiment are described. The difference lies in the provision of two first connecting members 21, each of which is L-shaped. One end of the first connecting member 21 is rotatably connected to the rolling member 1, and the other end of the first connecting member 21 is detachably connected to the second connecting member 22, which extends parallel to the first axis.
[0059] One end of the two first connecting members 21 is rotatably connected to the rolling member 1, so that the rolling member 1 can rotate relative to the first connecting member 21, and the other end of the two first connecting members 21 is fixedly connected to the second connecting member 22. The operator can hold the second connecting member 22 to push the rolling member 1 to roll on the printing.
[0060] In order to more conveniently roll the rolling member 1, in this embodiment, the textile printing fastness testing device also includes a holding member 3, which is arranged on the side of the second connecting member 22 away from the rolling member 1. The holding member 3 extends in a direction perpendicular to the first axis and is fixedly connected to the second connecting member 22.
[0061] The gripping member 3 and the second connecting member 22 can be connected using existing bolts, ensuring a secure connection and easy disassembly. The operator can grip the gripping member 3 and apply downward force to roll the rolling member 1 onto the printed piece, reducing labor intensity. The outer surface of the gripping member 3 can also be provided with a cushioning member to enhance grip comfort. The cushioning member can be made of readily available rubber, which is easily available and easy to process.
[0062] The first connecting member 21 and the second connecting member 22 can be connected by nuts or clamped. Figure 5For example, the first connecting member 21 is rod-shaped and one end of the first connecting member 21 connected to the second connecting member 22 is provided with a thread, the second connecting member 22 is plate-shaped, and the second connecting member 22 is provided with a mounting hole, the mounting hole passes through the second connecting member 22, and the mounting hole is used to penetrate the first connecting member 21. The first connecting member 21 passes through the mounting hole and two nuts 23 are sleeved on the first connecting member 21. The second connecting member 22 is sandwiched between the two nuts 23. When the nuts 23 are tightened, the first connecting member 21 is fixed to the second connecting member 22. When the nuts 23 are loosened, the first connecting member 21 is detachable.
[0063] The rolling element 1 is rotatably connected to the first connecting member 21, which can be a bearing connection or a ball joint connection. Schematically, the rolling element 1 and the first connecting member 21 are connected via a bearing. Grooves are provided on both end faces of the rolling element 1 to accommodate bearings. The outer ring of the bearing forms an interference fit with the inner wall of the groove, and the inner ring of the bearing forms an interference fit with the first connecting member 21. The bearing connection ensures that the rolling element 1 can rotate relative to the first connecting member 21 and reduces wear on the rolling element 1 during rotation relative to the first connecting member 21.
[0064] In order to adapt to rolling elements 1 of different lengths, the mounting hole can be configured as an elongated hole. When a rolling element 1 of a different length needs to be replaced, the first connecting member 21 can be removed from the rolling element 1 and a new rolling element 1 can be installed. Since the mounting hole is an elongated hole, the first connecting member 21 can slide along the elongated hole and be locked by a nut.
[0065] One or more rolling members 1 can be provided between the two first connecting members 21. For printing of different areas, the two first connecting members 21 can be removed and replaced with rolling members 1 of different lengths; alternatively, the number of rolling members 1 can be changed to adjust the length of the rolling members 1, thereby improving test accuracy.
[0066] When a rolling member 1 is arranged between the two first connecting members 21, when replacing the rolling member 1, first loosen the nut 23 used to connect the first connecting member 21 and the second connecting member 22, separate the second connecting member 22 and the first connecting member 21, then remove the first connecting member 21, separate the first connecting member 21 from the bearing on the rolling member 1, select a rolling member 1 of appropriate length and install the bearing in the groove of the rolling member 1, tighten the first connecting member 21 and the bearing, and finally connect the first connecting member 21 and the second connecting member 22 with the nut 23, so that the first connecting member 21, the second connecting member 22 and the rolling member 1 are fixed together, and the operator pushes the second connecting member 22 to make the rolling member 1 roll on the printing.
[0067] When a plurality of rolling elements 1 are arranged between two first connecting elements 21, adjacent rolling elements 1 can be fixed by insertion, thereby changing the length of the rolling elements 1 between the two first connecting elements 21. Specifically, the rolling element 1 connected to one of the first connecting elements 21 through the bearing is provided with a groove, the rolling element 1 connected to the other first connecting element 21 through the bearing is provided with a protrusion, and the remaining rolling elements 1 are both provided with a groove and a protrusion on the two end faces, which are inserted and matched through the groove and the protrusion, thereby facilitating the connection or separation between the rolling elements 1, and further changing the length of the rolling elements 1. When it is necessary to change the length of the rolling elements 1, first loosen the nut 23 used to connect the first connecting element 21 and the second connecting element 22, separate the second connecting element 22 and the first connecting element 21, then separate two rolling elements 1, and increase or decrease the number of rolling elements 1 to change the length of the rolling elements 1. Finally, connect the first connecting element 21 and the second connecting element 22 with the nut 23, so that the first connecting element 21, the second connecting element 22 and the rolling element 1 are fixed together, and the operator pushes the second connecting element 22 to make the rolling element 1 roll on the printing.
[0068] Obviously, the above embodiments of the present application are merely examples for clear illustration of the present application, and are not a limitation on the embodiments of the present application. For those skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and impossible to enumerate all the embodiments.
