Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, specifically to a friction color fastening device with a material changing structure. Background Technology

[0002] A rubbing fastness tester is a device used to test the color transfer of fabrics or printed and dyed products during rubbing. It primarily assesses the color fastness of fabrics during use by simulating the rubbing process between the fabric and other objects. Existing rubbing fastness testers often use a fixed clamp; after one fabric test, the machine needs to be stopped, disassembled, and re-clamped. This prevents automatic switching of the fabric position and the simultaneous testing and fabric removal, resulting in prolonged downtime and reduced testing efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a rubbing color fastening device with a material changing structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a friction color fastening device with a material changing structure, comprising:

Detailed Implementation

[0021] 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.

[0022] Please see Figure 1 , 2 As shown in Figures 3, 4, and 5, this utility model provides a technical solution: a friction color fastening device with a material changing structure, comprising: a support platform 1; a linear guide rail 4, the linear guide rail 4 being placed at the bottom of the support platform 1, a movable frame 3 being slidably connected to the top of the linear guide rail 4, the support platform 1 having a groove for the movable frame 3 to move, a driving part for driving the movable frame 3 to reciprocate sliding being installed on the top of the support platform 1, a linkage plate 5 being rotatably connected to the middle of the movable frame 3, an electric telescopic rod 6 for lifting the linkage plate 5 being fixedly installed on the top of the support platform 1, a crossbar being fixedly connected to the top of the electric telescopic rod 6; a friction part being adjustablely installed at the end of the linkage plate 5, a placement plate 11 being slidably placed on the top of the support platform 1, a linear module 16 for driving the placement plate 11 to move in a direction perpendicular to the linkage plate 5 being fixedly connected to the bottom of the support platform 1, and multiple sets of pressing components for fixing the fabric being symmetrically arranged on the top of the support platform 1.

[0023] It should be noted that the drive box 2 in this embodiment is equipped with a controller and an operation panel. The cut fabric is fixed to the top of the placement plate 11 by the pressing assembly. Different standard attached fabrics are installed at the corresponding ends of the linkage plate 5. The linear module 16 drives the placement plate 11 to move, so that the placement plate 11 moves the corresponding fabric to the bottom of the linkage plate 5. The electric telescopic rod 6 resets and drives the end of the linkage plate 5 to move downward, so that the standard attached fabric contacts the fabric to be tested. The drive box 2 drives the moving frame 3 to reciprocate on the top of the linear guide rail 4. The moving frame 3 drives the standard attached fabric to reciprocate and rub against the fabric on the top of the placement plate 11 through the linkage plate 5. Under the action of the timer, when the friction ends, the drive box 2 stops working, and the electric telescopic rod 6... The linkage plate 5 is lifted from the middle, separating the friction part at the end of the linkage plate 5 from the placement plate 11. At this time, the linear module 16 drives the placement plate 11 to move in the direction perpendicular to the linkage plate 5, conveying the remaining fabric to the bottom of the linkage plate 5 to correspond to the friction part. Then the electric telescopic rod 6 is reset, so that the standard attached fabric rubs against the fabric. This cycle is repeated, so that the placement plate 11 automatically switches positions, so that different fabrics correspond to the friction parts. In this way, after one clamping and a single friction is completed, the equipment automatically switches the fabric. The disassembly of the processed fabric does not affect the use of the existing test.

[0024] In one embodiment, a fixed frame 18 is fixedly connected to one end of the top of the support platform 1, and a pressing roller 19 is provided inside the fixed frame 18 for lifting and lowering. A support roller is rotatably connected inside the fixed frame 18 and below the pressing roller 19.

[0025] It should be noted that, in this embodiment, an n-shaped frame is slidably connected inside the fixed frame 18, and the extrusion roller 19 is rotatably installed inside the frame. A screw is threadedly connected to the middle of the fixed frame 18, and the screw is rotatably connected to the frame. A handwheel that drives the support roller to rotate is rotatably connected to the outside of the fixed frame 18, so that the wet standard attachment is placed between the extrusion roller 19 and the support roller, and the standard attachment is squeezed by rotating the support roller.

[0026] In one embodiment, the drive unit includes a drive box 2 in which a motor is installed. A crank 14 fixed to the output end of the motor is rotatably connected to one side of the drive box 2. A connecting rod 15 is rotatably connected to one end of the crank 14. One end of the connecting rod 15 is rotatably connected to the moving frame 3.

[0027] It should be noted that in this embodiment, the output end of the motor drives one end of the connecting rod 15 to rotate around the motor shaft through the crank 14, and the other end of the connecting rod 15 pulls the moving frame 3 to slide back and forth along the linear guide rail 4, thereby driving the friction part to rub the fabric back and forth.

[0028] In one embodiment, the friction part includes a fixed cylinder 7 fixed to the end of the linkage plate 5, a motor 8 fixedly connected inside the fixed cylinder 7, an mounting plate 9 fixedly connected to the output end of the motor 8, and a fixed rod 10 fixedly connected to the middle of the mounting plate 9 for fixing the standard attached cloth.

[0029] It should be noted that in this embodiment, the fixing rod 10 is symmetrical about the mounting plate 9. A rubber clamping ring is sleeved on the outer side of the fixing rod 10. Different standard attachments are installed at both ends of the fixing rod 10, or wet and dry standard attachments are fixed at the ends of the fixing rod 10. When it is necessary to switch the standard attachments, the motor 8 drives the mounting plate 9 to move. Under the action of the limit switch, the ends of the two fixing rods 10 are swapped, thereby switching the standard attachments.

[0030] In one embodiment, a pull plate 17 is fixedly connected to the moving slide of the linear module 16, the end of the pull plate 17 is fixedly connected to the placement plate 11, and a limiting block that is slidably connected to the support platform 1 is fixedly connected to the bottom of the placement plate 11.

[0031] It should be noted that, in this embodiment, the linear module 16 includes a motor fixed to the bottom of the support platform 1 and a lead screw fixed to the end of the motor. The outer side of the lead screw is threaded with a movable slide that is slidably connected to the support platform 1. The movable slide moves at the bottom of the support platform 1 under the drive of the lead screw. During this period, the movable slide drives the pull plate 17 to move. Multiple magnets are fixed at equal intervals on the outer side of the placement plate 11, and a Hall sensor that cooperates with the magnet disk is fixed on the top of the support platform 1. Thus, the placement plate 11 can be stopped after moving to a designated position through the linear module 16, the Hall sensor and the controller.

[0032] In one embodiment, the clamping assembly includes a plurality of support frames 12, with a semi-circular fixed pressure rod 13 rotatably connected between the support frames 12. A drive rod for driving the fixed pressure rod 13 to rotate is rotatably connected to the outer side of the support frame 12, and the end of the drive rod is located at a position offset from the center of the fixed pressure rod 13.

[0033] It should be noted that, in this embodiment, when the fabric is fixed, the fabric is placed between the fixed pressure rod 13 and the support platform 1. The fixed pressure rod 13 is rotated by the drive rod. Since the rotation position of the drive rod and the support frame 12 is deviated from the center position of the fixed pressure rod 13, the fixed pressure rod 13 will squeeze and fix the fabric under the action of compression.
