Abstract
Description
Technical Field
[0001] This utility model relates to the field of daily chemical product washing, specifically a soiled cloth dyeing device for evaluating the performance of laboratory detergents. Background Technology
[0002] In the detergent industry, detergency is one of the key indicators for measuring its performance. Corresponding detergency testing experiments require soiled cloths with different stains. The current industry standard GB / T13174-2021, "Determination of Detergency and Cyclic Washing Performance of Detergents for Clothing," specifies three standard soiled cloths (JB-01 carbon black oil-stained cloth, JB-02 protein-stained cloth, and JB-03 sebum-stained cloth) and their preparation methods, which can be used to verify the detergency against oil, dust stains, protein stains, and human body oil stains.
[0003] However, the methods for preparing soiled cloths specified in the standard require specialized dyeing equipment, such as rollers with soiling tanks, which are more suitable for standardized, large-scale continuous production and have limited applicability in small-scale laboratory testing. Furthermore, the types of stains covered in the standard are relatively limited and differ significantly from common stains in real life, which may lead to an incomplete and inaccurate evaluation of detergent performance. Therefore, it is necessary to develop a soiled cloth dyeing device that can be used for laboratory detergent performance evaluation. This device would allow for the rapid and convenient preparation of soiled cloths, thus providing strong support for accurate detergent performance assessment in the laboratory. Utility Model Content

Detailed Implementation
[0017] A preferred embodiment of the present invention will now be described in conjunction with the accompanying drawings, providing a clear and complete description of the technical solution in this preferred embodiment.
[0018] A soiled cloth dyeing device for evaluating the performance of laboratory detergents includes: a tray-type dispersion tank 1 for storing soiled liquid and a dyeing tank 2 for dyeing cloth, arranged side by side. The dyeing tank 2 has a soiled cloth placement area 21 in the center and a liquid collection tank 211 around the soiled cloth placement area 21. A plastic film 22 for covering soiled cloth 100 is laid on top of the soiled cloth placement area 21. A clamping frame 11 is provided above the tray-type dispersion tank 1. The clamping frame 11 extends from both ends of the tray-type dispersion tank 1 and is connected to a left rotating lifting mechanism 12 and a right rotating lifting mechanism 13 respectively provided on both sides of the tray-type dispersion tank 1. A plurality of clamps 111 for clamping the soiled cloth 100 are provided in the middle of the clamping frame 11.
[0019] The tray-type dispersion tank 1 and the dyeing tank 2 share a first telescopic cylinder 3 on one side and a slide 4 on the other side. The output end of the first telescopic cylinder 3 is connected to the left rotation lifting mechanism 12, and the right rotation lifting mechanism 13 is slidably connected in the slide 4.
[0020] Specifically, the left rotating lifting mechanism 12 includes a left rotating motor 121, the output end of which is connected to a left telescopic rod 122, the output end of which is vertically upward and connected to one end of the clamping frame 11; the right rotating lifting mechanism 13 includes a right rotating motor 131, the output end of which is connected to a right telescopic rod 132, the output end of which is vertically upward and connected to the other end of the clamping frame 11.
[0021] The preparation process of this utility model of soiled cloth is as follows: Step 1) Prepare the soiled liquid and perform pretreatment. Inject the prepared soiled liquid into the tray-type dispersion tank 1, and install a constant temperature water bath at the bottom of the tray-type dispersion tank 1. Turn on the stirrer 51 and stir the soiled liquid for 1 minute to ensure that the soiled liquid is uniform and there is no stratification or stain settling.
[0022] Step 2) Use clip 111 to clamp the cut fabric. The left telescopic rod 122 and the right telescopic rod 132 retract so that the lower end of the fabric just touches the sewage in the tray-type dispersion tank 1. Start the left rotary motor 121 and the right rotary motor 131. The left telescopic rod 122 and the right telescopic rod 132 rotate counterclockwise so that the fabric is immersed in the sewage in the tray-type dispersion tank 1. The output end of the first telescopic cylinder 3 extends to completely flatten the fabric and soak for 1 minute.
[0023] Step 3) Start the left rotary motor 121 and the right rotary motor 131, causing the left telescopic rod 122 and the right telescopic rod 132 to rotate clockwise, pulling the fabric out of the dirty liquid. The output ends of the left telescopic rod 122 and the right telescopic rod 132 extend, allowing the fabric to hang naturally in the air for 30 seconds. Then, the first telescopic cylinder 3 retracts, driving the clamping frame 11 to move closer to the dirty cloth placement area 21 of the dyeing tank 2. Start the left rotary motor 121 and the right rotary motor 131 again, causing the clamping frame 11 to continue rotating clockwise, so that the fabric is laid flat in the dirty cloth placement area 21. Then release the clamp 111, and the left rotary motor 121 and the right rotary motor 131 reset.
[0024] Step 4) Place absorbent paper in the collection tank 211 opened around the soiled cloth placement area 21 of the dyeing tank 2, and put down the plastic film 22 so that the plastic film 22 covers the soiled cloth placement area 21 flat.
[0025] Step 5) Roll the fabric. First, roll it horizontally from one side of the fabric to the other side, rolling it 8 times in the same direction. Then roll it 8 times in the opposite direction. After that, roll it vertically in the same way as the horizontal rolling method.
[0026] Step 5) Carefully peel off the plastic film 22 covering the cloth, hold one end of the cloth with a clip, hold the clip, pull up the cloth, and place it on the wire rack to air dry naturally, thus making a soiled cloth 100.
[0027] Specifically, a stirring rack 5 is fixed above the tray-type dispersion tank 1, and a stirrer 51 is fixed on the stirring rack 5.
[0028] Through the above design, this utility model uses a mechanical stirring device when dispersing the sewage, which can avoid problems such as the separation of the sewage and the sedimentation of stains during the dyeing process of the soiled cloth, and ensure the uniformity of the sewage.
[0029] Specifically, a plurality of fixing rings 14 are installed in the middle of the clamping frame 11, and each fixing ring 14 is connected to the clamp 111.
[0030] Specifically, the dyeing tank 2 is a square tank, and rolling grooves 23 are provided around the dyeing tank 2. A roller 24 for rolling the soiled cloth placement area 21 is rolled on the top of the dyeing tank 2. Roller blades 241 are rolled in the rolling grooves 23 at both ends of the roller 24. The length of the roller 24 is greater than the widest width of the soiled cloth 100.
[0031] Specifically, the roller 24 is made of black rubber or ABS.
[0032] Specifically, the dyeing tank 2 is made of acrylic.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
