Description

Technical Field

[0001] The utility model relates to the technical field of color fastness testing, in particular to a device for controlling the moisture content of a friction cloth. Background Art

[0002] Color fastness to rubbing is an important evaluation content in my country's existing textile quality evaluation system. The rubbing color fastness test includes dry rubbing and wet rubbing. The wet rubbing process requires the use of rubbing cloth, which needs to be humidified first to make its moisture content reach 95%-100%.

[0003] The laboratory usually uses an adjustable squeezing device to adjust the moisture content of the friction cloth. By adjusting the pressure between the two rollers, when the wet friction cloth passes through the rollers, the excess water is squeezed out. The wet friction cloth after squeezing is weighed on an electronic balance to calculate the moisture content. Since the pressure between the rollers needs to be adjusted manually, in general, the moisture content of the wet friction cloth after the first squeezing is usually not within the standard range. Therefore, the inspector needs to adjust the roller pressure multiple times to make the moisture content of the friction cloth meet the requirements, resulting in long test time and low work efficiency. Utility Model Content

[0004] The utility model aims to overcome the above-mentioned shortcomings and provides a device for controlling the moisture content of friction cloth, which automatically controls the moisture content of friction cloth more accurately and reduces the influence of the moisture content of friction cloth on the wet friction color fastness result; avoids repeated adjustment of roller pressure and improves work efficiency.

[0018] See also Figure 1 and Figure 2 The utility model relates to a device for controlling the moisture content of a friction cloth, comprising a base 1, an electronic balance 2, an operating screen 3 and an extrusion assembly, wherein the base 1 is provided with an electronic balance 2, a tray of the electronic balance 2 extends out of the base 1, the operating screen 3 is arranged at the front side of the base 1, the extrusion assembly comprises a column 4, a fixed extrusion arm 5 and a movable extrusion arm 6, the column 4 is fixed to one side of the left and right sides of the base 1, the movable extrusion arm 6 and the fixed extrusion arm 5 are arranged on the column up and down, the fixed extrusion arm 5 is fixedly arranged on the column 4, and the fixed extrusion arm 5 is fixedly arranged on the column 4. A fixed extrusion block 7 is provided at one end of the pressure arm 5, and the movable extrusion arm 5 is movably arranged on the column 4, and a movable extrusion block 8 is provided at one end of the movable extrusion arm 6, and a sliding sleeve 9 is provided at the other end. The gear 10 and the column 4 are arranged in the sliding sleeve 9, and the column 4 is provided with a rack 4.1 corresponding to the gear 10. The gear 10 is driven by a motor 11, and the motor 11 is fixed outside the sliding sleeve 9. The friction cloth after humidity adjustment is arranged between the fixed extrusion block 7 and the movable extrusion block 8. The motor 11, the operating screen 3, and the electronic balance 2 are all electrically connected to the controller.

[0019] The fixed extrusion block 7 is arranged just above the tray. The fixed extrusion block 7 is provided with guide surfaces around it. A plurality of guide surfaces converge at one point to facilitate the extruded water to fall into the tray of the electronic balance.

[0020] The tray is surrounded by enclosures to prevent the squeezed water from being lost.

[0021] The fixed extrusion block 7 and the movable extrusion block 8 are both made of hydrophobic material, and the contact surfaces between the two are flat.

[0022] Working principle:

[0023] The electronic balance 2 weighs the weight of the humidified friction cloth, completely immerses the humidified friction cloth in water, and places the humidified friction cloth on the fixed extrusion block 7. The driving motor 11 drives the gear 10, the sliding sleeve 9 and the movable extrusion arm 6 to move downward along the rack 4.1. The movable extrusion block 8 approaches the fixed extrusion block 7 to fully squeeze the friction cloth. The excess water squeezed out falls into the tray of the electronic balance 2, and the electronic balance weighs the weight of the squeezed water.

[0024] The electronic balance uploads the weighing data (including the weight of the humidified friction cloth and the weight of the squeezed water) to the controller, which analyzes the collected weighing data in real time to calculate the actual moisture content. When the actual moisture content reaches the preset moisture content range, the controller controls the motor to stop rotating, and the active squeeze block no longer squeezes the friction cloth. The weighing data and the preset moisture content range are displayed on the operation screen, which is convenient for the operator to monitor and record.

[0025] Actual moisture content = squeezed water weight / wet friction cloth weight, which greatly simplifies the moisture content measurement process.

[0026] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
