[0019] As a further solution of the present invention: wherein, direction-changing rollers are respectively provided at the discharge port and the feed port.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In the detection device of this embodiment, when the rotating cleaning cylinder is in contact with the fabric, the contact rod will be deflected in the opposite direction of the rotation of the cleaning cylinder under the tension of the fabric. After the deflection, the contact rod is in an inclined state, and at this time, it will push the pushing rod to move inside the cleaning cylinder. The pushing rod acts on the rubber pad that blocks the water outlet, and the rubber pad is separated from the water outlet. After the separation, the water outlet starts to discharge water, and then the water is flushed onto the fabric, completing the flushing of the fabric.

[0022] 2. The detection device in this embodiment, when the contact rod contacts the fabric, the water outlet hole is passively opened, and the water inside the cleaning cylinder is discharged from the opened water outlet hole under the action of pressure and acts on the fabric. When the fabric leaves the contact rod, due to the action of the reset coil spring, the contact rod returns to its initial vertical state. At this time, the force applied to the pushing rod disappears, and the rubber pad covers the water outlet hole again, thereby achieving the effect of blocking the water outlet hole. Since the part of the cleaning cylinder that is not in contact with the fabric is in a closed state, and only the position in contact with the fabric is in an open state, on this basis, the water is discharged from the opened water outlet with greater intensity, and the flushing effect is better when acting on the fabric.

[0023] 3. When installing the detection equipment in this embodiment, the contact rod is rotated clockwise, and the limit rod retracts, so that the fixing frame can be easily inserted into the through hole. Then the contact rod is released, and the contact rod returns to its original state under the action of the reset coil spring. At this time, the adjustment gear is reversed, and the limit rod is pushed out to contact the inner wall of the cleaning cylinder, thereby achieving the purpose of fixing, thereby realizing the above-mentioned effect of disassembly and maintenance of the water outlet assembly.

[0024] 4. The detection device in this embodiment can drive the rotating gear to rotate on the fixed tooth plate through the movement of the connecting rod. The rotating rotating gear cooperates with the concentric shaft to drive the rotating wheel inside the sliding block to rotate. During the rotation process, the rotating wheel will cooperate with the eccentrically designed resistance rod to move up and down inside the fixed plate, thereby achieving the effect of lifting or lowering. With the flushing effect, the gaps between the fabric fibers can be better flushed. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] See also Figure 1 , which is the washing device part of the water washing color fastness testing equipment, and the device is also connected to the drying device, and is dried after the washing is completed. The device includes a washing box 10, and the washing box 10 is provided with a feed inlet and a discharge port. The washing box 10 is provided with a flushing mechanism 20 inside, and a pulling mechanism 30 is provided inside the washing box 10 and above the flushing mechanism 20. In this embodiment, the fabric is put into the washing box 10 through the feed inlet, and then passes through the flushing mechanism 20 and the pulling mechanism 30, and finally discharged through the discharge port, so as to achieve the flushing of the fabric inside the washing box 10.

[0038] In order to allow the fabric to change direction better inside the washing box 10 , a direction-changing roller 11 is provided at the discharge port and the feed port, and the fabric can change direction on the direction-changing roller 11 .

[0039] like Figure 2 and Figure 3As shown, on the basis of the prior art, the flushing mechanism 20 includes a cleaning cylinder 21 symmetrically distributed inside the washing box 10, and the cleaning cylinder 21 rotates inside the washing box 10. The surface of the cleaning cylinder 21 is provided with evenly distributed through holes 22, and a water outlet assembly 23 is embedded in the through hole 22. The water outlet assembly 23 includes a fixed frame 231 embedded in the through hole 22, and the interior of the fixed frame 231 is rotatably connected to a contact rod 232 through a rotating shaft. A reset disc spring 233 is arranged between the contact rod 232 and the inner wall of the fixed frame 231, and the reset disc spring 233 is sleeved on the rotating shaft for restoring the contact rod 232 to an initial state. A water outlet hole 235 blocked by a rubber pad 234 is arranged at the bottom of the fixed frame 231, and a pushing rod 236 is arranged between the rubber pad 234 and the contact rod 232. In this embodiment, when the rotating cleaning cylinder 21 is in contact with the fabric, the contact rod 232 will be deflected in the opposite direction of the rotation of the cleaning cylinder 21 under the tension of the fabric. After the deflection, the contact rod 232 is in an inclined state, and at this time, it will push the pushing rod 236 to move toward the inside of the cleaning cylinder 21. The pushing rod 236 acts on the rubber pad 234 that blocks the water outlet 235, and the rubber pad 234 and the water outlet 235 are separated. After the separation, the water outlet 235 starts to discharge water, and then the water is flushed onto the fabric, completing the flushing of the fabric.

[0040] In order to increase the water output intensity, a pressure pump is provided inside the cleaning cylinder 21. The pressure pump can circulate the water inside the washing tank 10 into the cleaning cylinder 21, and can keep the pressure inside the cleaning cylinder 21 greater than the external pressure.

[0041] like Figure 4 and Figure 5 As shown, when the contact rod 232 contacts the fabric, the water outlet 235 is passively opened, and the water inside the cleaning cylinder 21 is discharged from the opened water outlet 235 under the action of pressure and acts on the fabric. When the fabric leaves the contact rod 232, due to the action of the reset coil spring 233, the contact rod 232 returns to its initial vertical state. At this time, the force applied to the pushing rod 236 disappears, and the rubber pad 234 covers the water outlet 235 again, thereby achieving the effect of blocking the water outlet 235. Since the cleaning cylinder 21 is in a closed state at the part that is not in contact with the fabric, and only the position that is in contact with the fabric is in an open state, on this basis, the water is discharged from the opened water outlet 235 with greater strength, and the flushing effect is better when acting on the fabric.

[0042] However, since the device needs to be used for a long time, it is inevitable that it will be damaged. If the water outlet component 23 is damaged, it needs to be disassembled. Therefore, the following improvements have been made.

[0043] like Figure 6 and Figure 7, Figure 8 As shown, a ninety-degree ring gear 2321 is provided at the bottom of the contact rod 232, and an adjusting gear 2322 is rotatably connected to the internal part of the fixed frame 231 and meshed with the ring gear 2321. Connecting shafts 2323 are fixedly installed on both sides of the adjusting gear 2322, and a threaded sleeve 2324 is fixedly installed at the end of the connecting shaft 2323 away from the adjusting gear 2322, and the internal thread of the threaded sleeve 2324 is connected to a threaded rod. In this embodiment, by rotating the contact rod 232 clockwise, the contact rod 232 will drive the adjusting gear 2322 meshing with it to rotate under the action of the gear ring 2321, and the adjusting gear 2322 cooperates with the connecting shaft 2323 to drive the threaded sleeve 2324 to rotate. During the rotation of the threaded sleeve 2324, the threaded rod meshing with it will be driven to move. Semicircular holes are provided on the front and rear sides of the fixed frame 231 (i.e., in the direction perpendicular to the rotation direction of the contact rod 232), and a limiting rod is fixedly installed on the threaded rod, which passes through the semicircular hole and can extend to the outside of the fixed frame 231 and has a shape corresponding to the semicircular hole. When the threaded rod rotates, the existence of the semicircular hole will prevent the limit rod from rotating, and then prevent the threaded rod from rotating, so that the threaded rod will achieve the effect of contraction; in the initial state (that is, when the contact rod 232 is vertical), the limit rod is in the state of being pushed out. When installing, the contact rod 232 is rotated clockwise, and the limit rod is retracted. The fixing frame 231 can be easily put into the through hole 22, and then the contact rod 232 is released. The contact rod 232 is restored to its original state under the action of the reset coil spring 233. At this time, the adjustment gear 2322 is reversed, and the limit rod is pushed out to contact the inner wall of the cleaning cylinder 21, achieving the purpose of fixing, thereby achieving the above-mentioned effect of disassembling and maintaining the water outlet assembly 23. In order to prevent the push rod 236 from affecting the clockwise rotation of the contact rod 232, a moving groove is provided on the contact rod 232, and one end of the push rod 236 can slide on the moving groove. When the contact rod 232 rotates clockwise, the push rod 236 will move from the top of the moving groove to the bottom, and will not limit the deflection of the contact rod 232.

[0044] Although the above method can achieve high-intensity flushing of the fabric, if the fabric can be properly pulled during the flushing process, the gaps between the fabric fibers can be flushed more thoroughly.

[0045] Therefore, if Fig. 9 and Fig.10As shown, the pulling mechanism 30 includes a connecting rod 31 slidably arranged inside the washing box 10, and guide grooves 32 for the connecting rod 31 to slide are opened on both sides of the washing box 10. A sliding block 33 is slidably connected inside the guide groove 32, and a rotating gear 34 is rotatably connected to the outer side of the sliding block 33. The rotating gear 34 is meshed with a fixed tooth plate 35 fixedly installed on the washing box 10. The sliding block 33 is provided with a group of symmetrically distributed contact components 36 on the end face away from the rotating gear 34, and a fixed plate 37 is fixedly installed on the top of the sliding block 33. A concentric shaft is fixedly installed at the axis center of the rotating gear 34, and one end of the concentric shaft away from the rotating gear 34 extends to the inside of the fixed plate 37 and is fixedly installed with a rotating wheel 38, and the eccentric part of the rotating wheel 38 is movably hinged with a resistance rod 39 that passes through the fixed plate 37. In this embodiment, the movement of the connecting rod 31 can drive the rotating gear 34 to rotate on the fixed tooth plate 35. The rotating rotating gear 34 cooperates with the coaxial shaft to drive the rotating wheel 38 located inside the sliding block 33 to rotate. During the rotation process, the rotating wheel 38 cooperates with the eccentrically designed resistance rod 39 to move up and down inside the fixed plate 37, thereby achieving the effect of lifting or lowering. Figure 5 When passing through the fabric, as the rotating wheel 38 rotates, the abutment rod 39 will reciprocate and continuously push the fabric upward, that is, give the fabric a pulling force, and the pulling force is intermittent, so that the fabric can be better cleaned after continuous pulling in combination with the previous flushing device. Among them, the rotation of the rotating gear 34 and the rotation of the above-mentioned washing cylinder 21 are driven by a power mechanism. Because the driving mechanism is a prior art, it will not be described in detail here.

[0046] At the same time, the connecting rod 31 moving inside the guide groove 32 drives the two contact components 36 to move left and right on the washing box 10, and then a large degree of pulling of the washed fabric can be achieved through a large displacement movement. Combined with the small pulling of the fabric by the above-mentioned resistance rod 39, better flushing of the gaps between the fabric fibers can be achieved.

[0047] Furthermore, the contact assembly 36 includes a support rod 361 hinged to the left and right sides of the sliding block 33, and a tension spring 362 is provided between the support rod 361 and the fixing plate 37. In this embodiment, the force of the support rod 361 on the fabric can be controlled by moving the connecting rod 31 left and right, thereby completing a large-scale pulling action on the fabric.

[0048] Furthermore, rollers for reducing the frictional force with the fabric are provided on the end surfaces of the contact rod 232, the abutment rod 39 and the support rod 361 that are in contact with the fabric.

[0049] The outlet is also provided with guide rollers 40 with adjustable spacing. After the fabric comes out of the outlet, it passes through the guide rollers 40. The guide rollers 40 can adjust the upper and lower spacing to adapt to the thickness of the fabric.

[0050] After the above-mentioned complete rinsing, it is dried by a drying device, and then the discoloration and staining levels are evaluated using a gray card. The above is the complete workflow of the present invention, and the above steps can be repeated when it is used next time.

[0051] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
