Description

Technical Field

[0001] This utility model relates to the field of clothing testing technology, and in particular to a color fastness tester for rubbing used in clothing testing. Background Technology

[0002] Clothing refers to all kinds of garments worn by people for covering the body, keeping warm, beautifying, and expressing personality or identity. There are many types of clothing, including work clothes and sportswear designed according to functional needs, as well as casual wear, formal wear, evening dresses, etc. designed according to seasons, occasions, and aesthetic needs. During the production process, clothing needs to be tested using a color fastness to rubbing tester. This test is mainly to examine the color stability of the fabric or finished garment under rubbing conditions and its color fastness to rubbing. Color fastness to rubbing is an important indicator for measuring whether the color of the fabric will transfer to other surfaces or whether the fabric itself will fade during the rubbing process.

[0003] Existing color fastness-to-rubbing testers test clothing fabrics by first placing the fabric on the top of the testing platform and fixing it in place. Then, the rubbing head is brought into contact with the outside of the fabric and rotated on top of the fabric to simulate the friction that the fabric may encounter during actual wear, use, or washing. During the rubbing process, the rubbing head will rub against the fabric, which may cause the color on the fabric surface to transfer or fade. After the rubbing is completed, the color change in the area where the rubbing head and the fabric are in contact is observed, and the color fastness of the fabric is evaluated.

[0004] Although existing rubbing color fastness testers can effectively test clothing fabrics, the rubbing head of traditional equipment is usually an integrated design with the instrument and cannot be replaced. As the usage time increases, the rubbing head is prone to wear, resulting in uneven friction pressure or deformation of the rubbing head surface, thus affecting the accuracy of the test results. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a rubbing color fastness tester for clothing testing, aiming to improve the problem that in the prior art, the rubbing head and the instrument are usually designed as an integral part and cannot be replaced. As the usage time increases, the rubbing head is prone to wear, resulting in uneven friction pressure or deformation of the rubbing head surface, thus affecting the accuracy of the test results.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A color fastness tester for rubbing used in garment testing includes a testing platform. A mounting frame is fixedly connected to the upper part of the testing platform. An electric push rod is fixedly connected to the outside of the mounting frame. A mounting shell is fixedly connected to the output end of the electric push rod. A first motor is fixedly connected inside the mounting shell. A mounting column is fixedly connected to the output end of the first motor. A connecting column is inserted into the mounting column. A rubbing head is fixedly connected to the bottom of the connecting column. A replacement component is provided inside the mounting column. An anti-offset component is provided on the right side of the outside of the testing platform. A placement plate is fixedly connected to the upper part of the testing platform.

[0008] The replacement component includes a crossbar, which is fixedly connected inside the mounting post. Sliders are slidably connected to both outer sides of the crossbar. Extension rods are fixedly connected to the front outer sides of both sliders. Springs are fixedly connected to the outer sides of both sliders. The springs are sleeved on both outer sides of the crossbar. L-shaped inserts are fixedly connected to the rear outer sides of both sliders.

[0009] Furthermore, the anti-deviation component includes a second motor, which is located on the outer right side of the detection platform. A rotating rod is fixedly connected to the output end of the second motor. The rotating rod is rotatably connected to the inside of the detection platform. Gears are fixedly connected to both outer sides of the rotating rod. Rack plates are provided on both inner sides of the detection platform. The two rack plates mesh with the two gears. Guide blocks are fixedly connected to the rear outer sides of the two rack plates. Mounting rods are fixedly connected to the upper part of the two rack plates. Pressure plates are fixedly connected to the outer side of the two mounting rods. Protrusions are fixedly connected to the lower part of the two pressure plates. The two protrusions are made of rubber.

[0010] Furthermore, a first through hole is provided on the outside of the mounting post, and the two extension rods are slidably connected inside the first through hole.

[0011] Furthermore, a second through hole is provided on both sides of the inside of the mounting column, and the two L-shaped plug rods are slidably connected inside the two second through holes.

[0012] Furthermore, slots are provided on both the inner and outer sides of the connecting column, and the two L-shaped plugs are inserted into the two slots.

[0013] Furthermore, a mounting ring is fixedly connected to the outer right side of the testing platform, and the second motor is fixedly connected inside the mounting ring.

[0014] Furthermore, guide rods are fixedly connected to both sides inside the testing platform, and two guide blocks are slidably connected to the outside of the two guide rods. Third through holes are opened on both sides of the upper part of the testing platform, and two rack plates are slidably connected to the inside of the two third through holes.

[0015] Furthermore, grooves are provided on both sides of the upper part of the placement plate, and the two protrusions engage with the two grooves.

[0016] This utility model has the following beneficial effects:

[0017] 1. In this utility model, when replacing the friction head, first move the extension rod to both sides, causing the bottom slider and the fixed L-shaped plug to move synchronously, compressing the spring to deform it. When the L-shaped plug disengages from the slot, the friction head and connecting post can be removed and replaced. During installation, insert the connecting post into the mounting post, release the extension rod, and under the spring's reaction force, the L-shaped plug will re-enter the slot. This design simplifies the replacement of the friction head, ensures consistent test conditions, reduces wear errors, and improves test accuracy and reliability.

[0018] 2. In this utility model, during testing, the garment fabric is first laid flat on the placement plate. The second motor is started to drive the rotating rod to rotate, which in turn drives the gears on both sides to rotate, thereby causing the rack plate to move down synchronously. The rack plate drives the mounting rod to move down, which in turn drives the pressure plate and the protrusions fixed at the bottom to move down. The two protrusions lock the two ends of the fabric into the grooves, thus fixing the fabric. This process ensures that the fabric remains stable throughout the entire test, thereby ensuring the accuracy of the test results. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figure 1 , Figure 3 and Figure 6 This utility model provides an embodiment of a color fastness tester for rubbing used in clothing testing, comprising a testing platform 1, a mounting frame 2 fixedly connected to the upper part of the testing platform 1, an electric push rod 3 fixedly connected to the outside of the mounting frame 2, a mounting shell 4 fixedly connected to the output end of the electric push rod 3, a first motor 5 fixedly connected inside the mounting shell 4, a mounting column 6 fixedly connected to the output end of the first motor 5, a connecting column 9 inserted into the mounting column 6, a friction head 7 fixedly connected to the bottom of the connecting column 9, a replacement component provided inside the mounting column 6 for easy replacement of the friction head 7, an anti-displacement component provided on the right side of the outside of the testing platform 1 to prevent displacement of the clothing fabric during testing, and a placement plate 27 fixedly connected to the upper part of the testing platform 1 for easy handling of the clothing fabric. During testing, the electric push rod 3 is activated, causing the mounting shell 4, which is fixed at the output end, to move downwards. The movement of the mounting shell 4 causes the first motor 5, which is fixed inside, to move synchronously. The movement of the first motor 5 causes the mounting column 6, which is fixed at the output end, to move. The movement of the mounting column 6 causes the connecting column 9, which is inserted inside, to move. The movement of the connecting column 9 causes the friction head 7, which is fixed at the bottom, to move, bringing the friction head 7 into contact with the garment fabric. Then, the first motor 5 is activated, causing the mounting column 6, which is fixed at the output end, to rotate. The rotation of the mounting column 6 causes the connecting column 9, which is inserted inside, to rotate and rub against the upper part of the garment fabric. The rotation of the friction head 7 simulates the friction force that the fabric may encounter during daily wear or washing, thereby testing the color fastness of the fabric.

[0029] The replacement component includes a crossbar 10, which is fixedly connected inside the mounting post 6. Sliding blocks 11 are slidably connected to both outer sides of the crossbar 10. Extension rods 12 are fixedly connected to the front outer sides of both sliding blocks 11, facilitating operator use. Springs 13 are fixedly connected to the outer sides of both sliding blocks 11, and are fitted onto both outer sides of the crossbar 10. L-shaped inserts 14 are fixedly connected to the rear outer sides of both sliding blocks 11. A first through hole 8 is provided on the outer side of the mounting post 6, and the two extension rods 12 are slidably connected inside the first through hole 8, facilitating the movement of the L-shaped inserts 14. Second through holes 15 are provided on both inner sides of the mounting post 6, and the two L-shaped inserts 14 are slidably connected inside the two second through holes 15, facilitating the movement of the L-shaped inserts 14. Slots 16 are provided on both the inner and outer sides of the connecting post 9, and the two L-shaped inserts 14 are inserted into the two slots 16, improving the stability of the friction head 7 installation.

[0030] Specifically, during the replacement of the friction head 7, the extension rod 12 needs to be moved to both sides first. This action causes the two sliders 11 fixed at the bottom to move laterally along the outside of the crossbar 10. The movement of the two sliders 11 is not independent, but synchronized with the movement of the two L-shaped inserts 14 fixed at the rear. When the sliders 11 move, the L-shaped inserts 14 also move. In addition, the movement of the two sliders 11 will exert a compressive force on the two springs 13, causing the springs 13 to deform. As the force on the springs 13 changes, the L-shaped inserts 14 will gradually disengage from the slots 16. At this time, the friction head 7 and the connecting post 9 can be easily removed from the mounting post 6 for replacement. To ensure the smooth replacement of the friction head 7, when installing a new friction head 7, firstly, the connecting post 9 fixed on the upper part of the friction head 7 needs to be reinserted into the mounting post 6. Then, the operator releases the previously moved extension rod 12. Under the reaction force of the two springs 13, the two L-shaped inserts 14 will spring back and accurately re-engage into the slot 16. This design greatly improves the replacement efficiency of the friction head 7 and avoids the impact of wear caused by long-term use on the test results. By ensuring that the friction head 7 is in the same state for each test, the error caused by the aging or wear of the friction head 7 can be effectively reduced, and the reliability and accuracy of the test results can be improved.

[0031] Reference Figure 2 , Figure 4 and Figure 5The anti-deviation component includes a second motor 18, which is located on the outer right side of the detection table 1. A rotating rod 19 is fixedly connected to the output end of the second motor 18. The rotating rod 19 is rotatably connected inside the detection table 1. Gears 20 are fixedly connected to both outer sides of the rotating rod 19. Two rack plates 21 are provided on both inner sides of the detection table 1, meshing with the two gears 20. Guide blocks 22 are fixedly connected to the rear outer sides of both rack plates 21. Mounting rods 24 are fixedly connected to the upper parts of both rack plates 21. Pressure plates 25 are fixedly connected to the outer sides of both mounting rods 24. Protrusions 26 are fixedly connected to the lower parts of both pressure plates 25. Both protrusions 26 are made of rubber. The softness of rubber allows the protrusions 26 to easily adapt to fabrics of different thicknesses and softness. When the fabric is inserted into the groove 28, the rubber... The protrusion 26 can better fit the surface of the fabric, avoiding deformation or damage to the fabric due to contact with hard objects. An installation ring 17 is fixedly connected to the right side of the outer side of the testing platform 1. The second motor 18 is fixedly connected inside the installation ring 17. The installation ring 17 facilitates the fixation of the second motor 18. Guide rods 23 are fixedly connected to both sides inside the testing platform 1. Two guide blocks 22 are slidably connected to the outside of the two guide rods 23. The guide rods 23 facilitate the movement of the guide blocks 22. The upper two sides of the testing platform 1 are provided with third through holes 29. Two rack plates 21 are slidably connected inside the two third through holes 29. The third through holes 29 facilitate the movement of the rack plates 21. The upper two sides of the placement plate 27 are provided with grooves 28. The two protrusions 26 engage with the two grooves 28 to ensure the stability of the garment fabric.

[0032] Specifically, during testing, the garment fabric to be tested is first laid flat on the upper part of the placement plate 27, ensuring the fabric surface is flat and wrinkle-free. Next, the second motor 18 is started. The second motor 18 drives the connected rotating rod 19 to rotate through its output end. During the rotation of the rotating rod 19, it drives the two gears 20 fixed on its outer sides to rotate. These two gears 20 mesh with the rack plate 21, causing the rack plate 21 to move downward synchronously. The downward movement of the rack plate 21 further drives the two mounting rods 24 fixed to it to move downward together. As the two mounting rods 24 move downward, the two pressure plates 25 connected to the mounting rods 24 also begin to move downward synchronously. The downward movement of the pressure plates 25 is driven by the protrusions fixed to them. 26 further affects the fixation of the fabric. When the two pressure plates 25 move downward, the two protrusions 26 fixed at their lower ends move downward simultaneously, ultimately firmly locking both ends of the fabric into the two grooves 28. This process ensures that the fabric is stably fixed during the test, avoiding any displacement of the fabric position caused by slight external forces or friction, improving the stability of the fabric during the test, and ensuring the accuracy of the test results. Especially in test items that require high stability, such as friction, tensile, or pressure tests, any slight displacement of the fabric may lead to test errors. Therefore, this fixing mechanism effectively prevents this from happening, ensuring that the fabric is fixed in the same state each time, thereby ensuring that the conditions for each test are consistent.

[0033] Working principle: When the friction head 7 needs to be replaced, firstly, move the extension rods 12 to both sides. The movement of the two extension rods 12 moves the two sliders 11 fixed at the bottom to both sides outside the crossbar 10. When the two sliders 11 move, they move the two L-shaped inserts 14 fixed at the rear side of the outside synchronously, and at the same time, they squeeze the two springs 13, causing the two springs 13 to deform under force. Then, when the two L-shaped inserts 14 disengage from the inside of the two slots 16, the friction head 7 and the connecting post 9 can be taken out from the inside of the mounting post 6 for replacement. During installation, insert the connecting post 9 fixed at the upper part of the friction head 7 into the inside of the mounting post 6. Then, release the two extension rods 12. Under the reaction force of the two springs 13, the two L-shaped inserts 14 can be re-inserted into the inside of the two slots 16. This makes it easy to replace the friction head 7, ensures that the test conditions are consistent each time, avoids errors caused by wear, and thus improves the reliability and accuracy of the test results.

[0034] During testing, the garment fabric is first laid flat on the upper part of the placement plate 27. Then, the second motor 18 is started, which drives the rotating rod 19 fixed at the output end to rotate. As the rotating rod 19 rotates, it drives the gears 20 fixed on both sides. The rotation of the two gears 20 drives the two meshing rack plates 21 to move downward synchronously. The movement of the two rack plates 21 drives the two mounting rods 24 fixed at the upper part to move downward synchronously. As the two mounting rods 24 move, they drive the two pressure plates 25 fixed at the outer part to move synchronously. The movement of the two pressure plates 25 drives the two protrusions 26 fixed at the lower part to move downward. The two protrusions 26 simultaneously engage the two ends of the garment fabric into the two grooves 28, thus fixing the garment fabric. This facilitates the fixing of the garment fabric to be tested and ensures that the fabric remains stable throughout the test, preventing it from moving due to slight external forces or friction, thereby guaranteeing the accuracy of the test results.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
