[0002] Rubbing color fastness refers to the evaluation of the staining or discoloration of the rubbing cloth using a gray sample card after the product is rubbed with dry or wet rubbing cloth.

[0003] The existing dry and wet friction color fastness test device can only install one test paper towel at a time, and it is impossible to achieve simultaneous comparative testing of two products or simultaneous dry and wet comparative testing of one product. Therefore, it is very necessary to design a dry and wet friction color fastness test device. Summary of the invention

[0004] The utility model aims to solve the above problems in the prior art and proposes a dry and wet friction color fastness testing device.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a dry and wet friction color fastness testing device, comprising a base, a main machine is installed on the base, and the main machine is connected to a reciprocating rod through a driving structure, characterized in that a counterweight guide block is installed on the reciprocating rod, the front end of the reciprocating rod is rotatably connected to the middle part of the switching arm, friction heads are installed at both ends of the switching arm, the friction head has a water storage tank, the friction head also has a water guide hole that penetrates the water storage tank, the counterweight guide block also has a locking assembly for locking the switching arm, and a placing table is also installed on the base, and pressure rollers are installed at both ends of the placing table for horizontal rotation.

[0006] The locking assembly includes a locking rod, which is vertically slidably connected to the counterweight guide block. A spring is provided between the locking rod and the counterweight guide block. The lower end of the locking rod has a locking tongue, and the middle part of the switching arm has a locking hole that matches the locking tongue.

[0007] The upper end of the locking rod is provided with a pulling handle.

[0008] A hand wheel is installed on the pressing roller.

[0009] The shape of the lock hole is square.

[0010] Compared with the prior art, this dry and wet rubbing color fastness test device has the following advantages:

[0011] In the utility model, two friction heads that can be directly injected with water are arranged. After the test paper towels are installed on the friction heads, the switching arm is used to reciprocate. When the switching arm overlaps with the reciprocating rod, water is injected into one of the friction heads to make the test paper towel at that location wet, thereby the dry friction color fastness test and the wet friction color fastness test can be performed on the same product at the same time; when the switching arm is perpendicular to the reciprocating rod, the two friction heads can be used to perform the dry friction color fastness test or the wet friction color fastness test on two products at the same time.

DETAILED DESCRIPTION

[0017] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0018] like Figure 1-Figure 4 As shown, the dry and wet friction color fastness test device includes a base 1, on which a main machine 6 is installed, and the main machine 6 adopts an existing product; the main machine 6 is connected to the reciprocating rod 4 through a driving structure 5. In this embodiment, the reciprocating rod 4 is reciprocated by the driving structure 5, which adopts the existing technology; a counterweight guide block 7 is installed on the reciprocating rod 4, and the front end of the reciprocating rod 4 is rotatably connected with the middle part of the switching arm 8, and friction heads 10 are installed at both ends of the switching arm 8. The friction head 10 has a water storage tank 10a, and the friction head 10 also has a water guide hole 10b that penetrates the water storage tank 10a. In this embodiment, the test tissue is fixed on the friction head 10, which adopts the existing technology, and water is injected into the water storage tank 10a to make the test tissue wet; the counterweight guide block 7 also has a locking component for locking the switching arm 8, and a placing table 2 is also installed on the base 1, and pressure rollers 3 are installed at both ends of the placing table 2 for horizontal rotation.

[0019] The locking assembly includes a locking rod 11, which is vertically slidably connected to the counterweight guide block 7. A spring 12 is provided between the locking rod 11 and the counterweight guide block 7. A locking tongue 11a is provided at the lower end of the locking rod 11. A locking hole 8a matching the locking tongue 11a is provided in the middle of the switching arm 8, and the shape of the locking hole 8a is square. With this structure, the switching arm 8 can be parallel to the movement direction of the reciprocating rod 4, or perpendicular to the movement direction of the reciprocating rod 4. After adjusting the position, release the pulling handle 11b to insert the locking tongue 11a into the locking hole 8a, thereby locking the position of the switching rod.

[0020] The locking rod 11 has a pull handle 11 b at its upper end.

[0021] A hand wheel 9 is installed on the pressing roller 3. With this structure, the two ends of the product are placed under the pressing roller 3, and the pressing roller 3 is driven to rotate by the hand wheel 9. The pressing roller 3 presses the end of the product onto the placement table 2. This adopts the existing technology. The product can be yarn or fabric, etc.

[0022] In the utility model, two friction heads 10 that can be directly injected with water are arranged. After the test paper towel is installed on the friction head 10, the switching arm 8 is used to reciprocate. When the switching arm 8 overlaps with the reciprocating rod 4, water is injected into one of the friction heads 10 to make the test paper towel at that location wet, so that the dry friction color fastness test and the wet friction color fastness test can be performed on the same product at the same time; when the switching arm 8 is perpendicular to the reciprocating rod 4, the two friction heads 10 can be used to perform the dry friction color fastness test or the wet friction color fastness test on two products at the same time.
