Description

Technical Field

[0001] The invention relates to the technical field of ink testing, in particular to a printing ink adhesion testing system. Background Art

[0002] At present, it is a very common problem that the printed patterns on clothing fall off. The main reason for the printing falling off is that when the clothing is washed, the fabric is rubbed and the patterns contact and rub against each other. Therefore, printing inks with good adhesion can increase the service life of clothing patterns.

[0003] A Chinese patent discloses a printing ink adhesion test device on UV spray products, and its publication number is CN117825271B. It mainly tests the adhesion of printing ink by friction in multiple directions, but the results of friction detection with pattern light cannot fully reflect the adhesion problem. Since the fabric itself has not deformed, the irregular deformation of the fabric will easily cause the print to fall off. In addition, some garments have a large printing surface, and there is still a printed pattern at the seam edge, which makes it impossible to test. Summary of the invention

[0004] The object of the present invention is to provide a printing ink adhesion testing system to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions: A printing ink adhesion test system, comprising an image collector for collecting fabric images, the image collector transmitting the collected images to a computer for analysis and processing, and also comprising a multi-faceted test fabric, a fabric rubbing unit, a horizontal motion unit, and a clamping disk; The multi-faceted experimental fabric is formed by sewing a plurality of fabrics on the same side, the cross-sectional shape of the multi-faceted experimental fabric is a polyline of a circular array with straight lines and end points as the center, and the surfaces of the multi-faceted experimental fabric are all coated with printing ink; The clamping disk clamps the two ends of the multi-sided experimental fabric, the horizontal motion unit drives the two clamping disks to move relative to or away from each other, the fabric rubbing unit drives the clamping disks to rotate and move vertically, the rotation angle of the two clamping disks is less than 360 degrees, and the rotation direction and vertical movement direction of the two clamping disks are opposite.

[0006] As a further solution of the present invention: it also includes a fixed disk, which is slidably connected to the clamping disk, and an electromagnetic pushing unit is arranged on the surface of the fixed disk, and a magnetic repulsive force is generated between the electromagnetic pushing unit and the clamping disk.

[0007] As a further solution of the present invention: a clamping groove for accommodating the multi-sided experimental fabric is opened on the surface of the clamping disk, and an electromagnetic pushing and clamping unit and a magnetic clamping plate are slidably connected on both sides of the inner wall of the clamping groove. The electromagnetic pushing and clamping unit applies a magnetic repulsive force to the clamping disk, and the magnetic clamping plate clamps the multi-sided experimental fabric.

[0008] As a further solution of the present invention: the opposite surfaces of the two magnetic clamping plates are provided with clamping patterns or clamping protrusions or cloth-grabbing barbs.

[0009] As a further solution of the present invention: a friction surface is provided on the surface of the clamping disk, and the friction surface is located within the included angle of the clamping groove.

[0010] As a further solution of the present invention: the rotating unit of the fabric kneading unit is arranged inside the clamping disk.

[0011] As a further solution of the present invention, a method for using a printing ink adhesion testing system comprises: S1: Printing patterns on the disassembled fabric of the multi-faceted experimental fabric by transfer printing ink process, selecting one side of the multi-faceted experimental fabric as a sewing side, sewing a plurality of the multi-faceted experimental fabrics into a cross shape or other polygonal shapes, energizing the electromagnetic pushing and clamping unit to use magnetic repulsion to push the magnetic clamping plate to move relative to each other, and clamping and fixing the multi-faceted experimental fabric in the clamping groove by the magnetic clamping plate; S2: The fixed disk, the electromagnetic pushing unit, and the clamping disk are driven to move relative to each other by the horizontal motion unit, and the multi-faceted experimental fabric is bent and folded between the two clamping disks. At this time, a part of the fabric is in contact with the friction surface, and the other part of the fabric is in contact with the fabric. At the same time, the electromagnetic pushing unit applies a magnetic repulsive force to the clamping disk to generate a certain elastic margin space and increase the pressure on the fabric. The fabric rubbing unit drives the clamping disk to rotate and reciprocate or vertically reciprocate, so that relative motion is generated between the fabric and the friction surface, between the fabrics, between the sewing edges and the sewing edges, and between the sewing edges and the fabrics to simulate the wear behavior of the fabrics in a real environment; S3: After completion, the horizontal motion unit drives the clamping disks to move in opposite directions, and the two clamping disks rotate in the same direction, so that the image collector collects multi-faceted printing images, and analyzes and processes them through the computer to obtain adhesion evaluation.

[0012] Compared with the prior art, the present invention has the following beneficial effects: After multiple multi-sided experimental fabrics are sewn together, they form a cross-shaped or hexagonal cross-sectional shape. When the fabrics are sewn together, they will produce sewn edges. Printing ink is adhered to both sides of the multi-sided experimental fabric. When the multi-sided experimental fabric is wrinkled and bent, the ink surfaces are more likely to contact and rub against each other, and the fabric is constantly deforming, thus simulating a real laundry scene. In addition, a portion of the ink will also come into contact with the clamping disk, thus simulating the friction between clothing and other external objects in a real environment. The sewn edges also bend and rub during the experiment, and the adhesion of the sewn edge pattern can be detected.

DETAILED DESCRIPTION

[0015] In this embodiment, please refer to Figure 1-Figure 3 , including an image collector 2 for collecting fabric images, the image collector 2 transmits the collected images to a computer 1 for analysis and processing, and also includes a multi-faceted experimental fabric 3, a fabric rubbing unit 4, a horizontal motion unit 5, and a clamping disk 8.

[0016] In this embodiment, the image collector 2 collects pattern information on the surface of the multi-faceted experimental cloth 3, and the computer 1 processes and analyzes the photos using software to obtain the shedding condition of the printing ink.

[0017] In this embodiment, the fabric rubbing unit 4 includes a rotating unit and a vertical motion unit. The rotating unit can be a motor, and the vertical motion unit can be a motor with a cam mechanism to realize the reciprocating motion of the clamping plate 8. The horizontal motion unit 5 can be a hydraulic rod or an electric push rod. The purpose of the horizontal motion unit 5 is to move the clamping plate 8 toward the middle, so that the multi-faceted experimental fabric 3 is naturally wrinkled and bent, and the wrinkled and bent multi-faceted experimental fabric 3 is clamped between the two clamping plates 8. Through the rotation and vertical staggered motion of the two clamping plates 8, the fabric inside the multi-faceted experimental fabric 3 is rubbed and simulated. Thereby detecting the printing adhesion effect.

[0018] In this embodiment, the multi-faceted experimental fabric 3 is formed by sewing a plurality of fabrics on the same sides. The cross-sectional shape of the multi-faceted experimental fabric 3 is a polylinear shape of a circular array with straight lines and end points as the center. The surfaces of the multi-faceted experimental fabric 3 are all coated with printing ink.

[0019] In this embodiment, please refer to Figure 2 After the multi-faceted experimental fabrics 3 are sewn together, a cross-shaped or hexagonal cross-section is formed. When the fabrics are sewn together, sewing edges are generated. Printing ink is adhered to both sides of the multi-faceted experimental fabrics 3. When the multi-faceted experimental fabrics 3 are wrinkled and bent, the ink surfaces are more likely to contact and rub against each other, and the fabrics are constantly deformed, thereby simulating a real laundry scene. In addition, a portion of the ink will also come into contact with the clamping plate 8, thereby simulating the friction between clothing and other external objects in a real environment. The sewing edges also bend and rub during the experiment, and the adhesion of the sewing edge pattern can be detected. The entire device has a simple structure, and performs a comprehensive ink adhesion test on the friction, rubbing, and sewing edges of clothing. The test results of this system are closer to the real results.

[0020] In this embodiment, the clamping disk 8 clamps the two ends of the multi-sided experimental fabric 3, the horizontal motion unit 5 drives the two clamping disks 8 to move relative to or away from each other, and the fabric rubbing unit 4 drives the clamping disks 8 to rotate and move vertically. The rotation angle of the two clamping disks 8 is less than 360 degrees, and the rotation direction of the two clamping disks 8 is opposite to the vertical movement direction.

[0021] In this embodiment, please refer to Figure 1 When the horizontal motion unit 5 drives the clamping plate 8 to move in opposite directions, the multi-faceted experimental fabric 3 can be unfolded, thereby facilitating the image acquisition device 2 to acquire images. During the simulation process, the clamping plate 8 moves relatively, and the multi-faceted experimental fabric 3 is deformed and bent due to the squeezing, so that the fabrics will have relative contact with each other, and the real environment in which the fabrics are used is simulated in the state of rotation and vertical opposite motion.

[0022] In this embodiment, a fixed disk 6 is further included, and the fixed disk 6 is slidably connected to the clamping disk 8. An electromagnetic pushing unit 7 is arranged on the surface of the fixed disk 6, and a magnetic repulsive force is generated between the electromagnetic pushing unit 7 and the clamping disk 8.

[0023] In this embodiment, a permanent magnet can be set on the surface of the clamping disk 8. The permanent magnet has opposite magnetism to the electromagnetic pushing unit 7. The electromagnetic pushing unit 7 is an electromagnet. After power is supplied, the magnetic repulsion force of the electromagnetic pushing unit 7 is applied to the clamping disk 8. A space margin is generated between the fixed disk 6 and the clamping disk 8. The magnetic force is used to apply pressure to the clamping disk 8, which can avoid the problem of fabric damage caused by excessive pushing of the horizontal motion unit 5.

[0024] In this embodiment, a clamping groove 81 for accommodating the multi-sided experimental fabric 3 is provided on the surface of the clamping disk 8, and an electromagnetic pushing and clamping unit 83 and a magnetic clamping plate 84 are slidably connected on both sides of the inner wall of the clamping groove 81. The electromagnetic pushing and clamping unit 83 applies a magnetic repulsive force to the clamping disk 8, and the magnetic clamping plate 84 clamps the multi-sided experimental fabric 3.

[0025] In this embodiment, the multi-sided experimental fabric 3 is inserted into the clamping groove 81 during installation, and the magnetic clamping plate 84 is clamped by powering the electromagnetic pushing and clamping unit 83, so that the magnetic clamping plate 84 clamps and fixes the multi-sided experimental fabric 3. The control method of the magnetic clamping plate 84 and the electromagnetic pushing and clamping unit 83 is consistent with the control method of the above-mentioned electromagnetic pushing unit 7.

[0026] In this embodiment, the opposite surfaces of the two magnetic clamping plates 84 are provided with clamping patterns or clamping protrusions or cloth-grabbing barbs. Since the multi-faceted experimental fabric 3 only needs to be immobile in the clamping groove 81 during the friction process, the clamping force requirement of the magnetic clamping plates 84 is not large. When a structure that increases the friction force, such as a pattern or a protrusion, is provided on the surface of the magnetic clamping plates 84, it is sufficient to ensure that the fabric will not slip out of the clamping groove 81. Similarly, the barbs provided in the magnetic clamping plates 84 can be inserted into the fabric to prevent the fabric from slipping out.

[0027] In this embodiment, the surface of the clamping plate 8 is provided with a friction surface 82, and the friction surface 82 is located within the angle of the clamping groove 81. A small amount of fabric can contact the friction surface 82, so the friction surface 82 can also contact the friction surface 82 during the rubbing process, thereby meeting the experimental requirements.

[0028] In this embodiment, the rotating unit of the fabric kneading unit 4 is arranged inside the clamping disk 8; the fabric kneading unit 4 has a rotating unit and a vertical motion unit. If the rotating unit is arranged inside the clamping disk 8, the vertical motion unit can control the horizontal motion unit 5 to move up and down, thereby separating the two motion structures and making it easier to install.

[0029] The method of using the printing ink adhesion test system includes: S1: Print patterns on the disassembled fabric of the multi-faceted experimental fabric 3 by using a transfer printing ink process, select one side of the multi-faceted experimental fabric 3 as a sewing side, sew a plurality of multi-faceted experimental fabrics 3 into a cross shape or other polygonal shapes, energize the electromagnetic pushing and clamping unit 83 to use magnetic repulsion to push the magnetic clamping plate 84 to move relative to each other, and clamp the multi-faceted experimental fabric 3 in the clamping groove 81 by the magnetic clamping plate 84; S2: The fixed plate 6, the electromagnetic pushing unit 7, and the clamping plate 8 are driven to move relative to each other by the horizontal motion unit 5, and the multi-faceted experimental fabric 3 is bent and folded between the two clamping plates 8. At this time, a part of the fabric is in contact with the friction surface 82, and the other part of the fabric is in contact with the fabric. At the same time, the electromagnetic pushing unit 7 applies a magnetic repulsive force to the clamping plate 8 to generate a certain elastic margin space and increase the pressure on the fabric. The fabric rubbing unit 4 drives the clamping plate 8 to rotate and reciprocate or vertically reciprocate, so that the fabric and the friction surface 82, the fabrics and the fabrics, the sewing edges and the sewing edges, and the sewing edges and the fabrics generate relative motion to simulate the wear behavior of the fabric in a real environment; S3: After completion, the horizontal motion unit 5 drives the clamping plates 8 to move in opposite directions. The two clamping plates 8 rotate in the same direction, so that the image collector 2 collects multi-faceted printed images, and analyzes and processes them through the computer 1 to obtain adhesion evaluation.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
