[0034] Embodiment 1:

[0035] like Figure 1-Figure 4 As shown, the utility model provides a liquid blocking roller assembly 1 for fabric dyeing, comprising: a frame 10, a first roller 20, a second roller 30 and a lifting device, a working space is arranged in the frame 10, the first roller 20 is rotatably arranged in the working space, the second roller 30 is rotatably and movably arranged in the working space, the second roller 30 is located above the first roller 20, the second roller 30 can selectively move toward the first roller 20 and contact with the first roller 20, the lifting device is connected to the frame 10 and has a movable driving end, the driving end is connected to the second roller 30 and is suitable for driving the second roller 30 to move away from the first roller 20.

[0036] In some embodiments, a working space is provided in the frame 10. For example, the frame 10 may include a base 11 and two support seats 12. The two support seats 12 are respectively provided on both sides of the base 11 in the width direction, and the two support seats 12 extend in the height direction. A working space is defined between the base 11 and the two support seats 12. The two support seats 12 are respectively provided with a first rotating hole and a second rotating hole facing each other. The two ends of the first roller 20 in the axial direction are respectively rotatably provided in the first rotating hole, and the two ends of the second roller 30 in the axial direction are respectively provided in the second rotating hole. It is worth noting that the second rotating hole is located above the first rotating hole, and the two support seats 12 are respectively provided with movable holes extending in the height direction, and the movable holes are connected to the second rotating hole, so that the second roller 30 can move along the extension direction of the movable hole and move toward the first roller 20 under the action of its own gravity and stop with the first roller 20. The lifting device is connected to the base 11 and / or the support seat 12 , and the driving end of the lifting device is connected to the second roller 30 and is suitable for driving the second roller 30 to move away from the first roller 20 in the height direction.

[0037] It can be understood that after dyeing, the fabric will enter between the first roller 20 and the second roller 30, and when the dyed fabric passes through the first roller 20, the second roller 30 relies on its own gravity to squeeze the dyed fabric, thereby intercepting excess liquid on the fabric. When the fabric is ready to enter between the first roller 20 and the second roller 30, the lifting device can operate to move the driving end, and the movement of the driving end can drive the second roller 30 to move away from the first roller 20 in the height direction, so that the second roller 30 is separated from the stop with the first roller 20. At this time, the fabric can smoothly enter between the first roller 20 and the second roller 30, and after the fabric enters between the first roller 20 and the second roller 30, the lifting device operates and moves the driving end. At this time, the second roller 30 moves toward the first roller 20 under the action of its own gravity and stops with the fabric.

[0038] Therefore, compared with the traditional method, the liquid-blocking roller assembly 1 of the present application can avoid the operator from manually lifting the second roller 30, thereby reducing the operator's work intensity; and the lifting device works to lift the second roller 30 compared to the operator manually lifting the second roller 30, which can avoid the operator from climbing up and down, making it more convenient to lift the second roller 30, thereby improving the production efficiency of the fabric; at the same time, it can avoid the operator from contacting the dye (the dye is corrosive), thereby avoiding the dye from affecting the safety of the operator.

[0039] It is worth mentioning that in the actual production process, since the wool on the fabric will fall off more or less, and the second roller may not rotate when cooperating with the moving fabric (at this time, the second roller cooperates with the fabric in a scraper form), when the fabric passes through the first roller and the second roller, the wool on the fabric will gradually accumulate at the contact point between the second roller and the fabric, and when too much wool accumulates, the rotation of the second roller will be stuck, thereby slowing down or even stopping the movement of the fabric, and causing the fabric to get stuck during the production process.

[0040] On the other hand, with respect to the liquid intercepting roller assembly 1 of the present application, when the operator finds that the movement speed of the fabric slows down, the operator can control the lifting device to work and move the second roller 30 away from the first roller 20, so that the wool accumulated at the joint of the second roller 30 and the fabric can pass through the second roller 30 smoothly, and after the movement speed of the fabric returns to normal, the lifting device is controlled to work and the second roller 30 is stopped above the fabric, thereby avoiding the fabric from getting stuck during the production process and improving the production efficiency of the fabric.

[0041] According to the liquid intercepting roller assembly 1 for fabric dyeing of the utility model, a lifting device is arranged on the frame 10, and the driving end of the lifting device is connected to the second roller 30. When the lifting device works, the driving end can drive the second roller 30 to move away from the first roller 20, so that the fabric can smoothly enter between the first roller 20 and the second roller 30 at the beginning of production, avoiding the operator to manually lift the second roller 30, thereby improving the production efficiency of the fabric, reducing the work intensity of the operator and avoiding the influence of the dye on the operator, and at the same time avoiding the fabric from getting stuck during the production process, further improving the production efficiency of the fabric.

[0042] Embodiment 2:

[0043] In this embodiment, based on the first embodiment, the lifting device comprises: a cam 40, which is rotatably disposed on the frame 10, and a protrusion 42 of the cam 40 can selectively contact the second roller 30 and is suitable for driving the second roller 30 to move in the height direction.

[0044] In some embodiments, the cam 40 includes a body 41 and a convex portion 42, the convex portion 42 is disposed on the outer peripheral wall of the body 41, and the cam 40 is rotatably disposed on the support seat 12. It can be understood that the convex portion 42 can rotate with the body 41, and during the rotation of the convex portion 42, it can contact the second roller 30 and move the second roller 30 away from the first roller 20 in the height direction. Therefore, in the above embodiment, the rotation of the cam 40 can drive the second roller 30 to move away from the first roller 20, and the movement of the second roller 30 is easy to control, making the operation of the liquid blocking roller assembly 1 convenient, reducing the work intensity of the operator, and improving the user experience.

[0045] It is worth noting that the number of cams 40 can be constructed as 1, 2 or other numbers, and there is no limitation here. When the number of cams 40 is 2, the two cams 40 are rotatably arranged on the two support seats 12 respectively, and the two cams 40 rotate and are respectively suitable for driving the two ends of the second roller 30 in the axial direction to move away from the first roller 20. Therefore, through the above arrangement, the movement of the second roller 30 can be made more stable, and the two ends of the second roller 30 are respectively subjected to force and move away from the first roller 20, so that the distance between the first roller 20 and the second roller 30 changes more smoothly, so that the fabric can more easily enter between the first roller 20 and the second roller 30.

[0046] According to some embodiments of the utility model, the second roller 30 is provided with a boss 321 suitable for cooperating with the cam 40, and the boss 321 is arranged around the outer peripheral wall of the second roller 30. In some embodiments, the outer peripheral wall of the second roller 30 is provided with a boss 321, the boss 321 protrudes from the outer peripheral wall of the second roller 30 in the radial direction, and the boss 321 is arranged around the outer peripheral wall of the second roller 30. It can be understood that the diameter of the boss 321 is greater than the diameter of the second roller 30, and thus, the structural strength of the boss 321 in the radial direction is greater than the structural strength of the second roller 30 in the radial direction. Therefore, by providing the boss 321 to cooperate with the cam 40, the damage to the second roller 30 when the second roller 30 cooperates with the cam 40 can be reduced, thereby extending the service life of the second roller 30, reducing the use cost of the liquid blocking roller assembly 1, and improving the production efficiency of the enterprise.

[0047] Embodiment three:

[0048] In this embodiment, based on the second embodiment, the second roller 30 includes: a roller portion 31 and a connecting portion 32, wherein the connecting portion 32 is constructed into two and respectively arranged at the two ends of the roller portion 31 in the axial direction, and the boss 321 is arranged on at least one of the connecting portions 32; wherein the connecting portion 32 is detachably connected to the roller portion 31.

[0049] It is understandable that the roller portion 31 is detachably provided with connecting portions 32 at both ends in the axial direction, and the connection methods of the roller portion 31 and the connecting portions 32 include, but are not limited to, clamping, threaded connection, or fixing by fasteners, which are not limited here. For example, the roller portion 31 is provided with threaded holes at both ends in the axial direction, and the two connecting portions 32 are provided with screws at one end in the axial direction, and the screws are threadedly connected with the threaded holes to fix the roller portion 31 and the two connecting portions 32.

[0050] It is worth noting that the boss 321 is arranged on the connecting part 32, so that the boss 321 will produce wear when cooperating with the cam 40. When the boss 321 is worn to a large extent, the operator only needs to replace the connecting part 32 to avoid replacing the entire second roller 30, thereby reducing the use cost of the liquid blocking roller assembly 1.

[0051] In some embodiments, a control rod 43 is provided on the cam 40. The control rod 43 can extend in the axial direction (in this case, the control rod 43 is provided on one side of the cam 40 in the thickness direction), and the control rod 43 can also extend in the radial direction (in this case, the control rod 43 is provided on the outer peripheral wall of the cam 40). The operator can drive the cam 40 to rotate by moving the control rod 43, which makes the rotation control of the cam 40 more convenient, thereby improving the operational convenience of the liquid blocking roller assembly 1.

[0052] In other embodiments, the liquid blocking roller assembly 1 further includes: a driving motor, the driving motor is provided with a rotatable output end, the output end is suitable for being fixedly connected to the cam 40, it can be understood that the driving motor can rotate the output end when it is working, the rotation of the output end can drive the cam 40 to rotate, and the rotation of the cam 40 can drive the second roller 30 to move away from the first roller 20 in the height direction. Therefore, the above-mentioned configuration can make the liquid blocking roller assembly 1 more automated, and further reduce the workload of the operator.

[0053] Embodiment 4:

[0054] In this embodiment, based on the third embodiment, the second roller 30 further includes: a roller 33, which is sleeved on the outer periphery of the roller portion 31. It can be understood that the design of the roller 33 can protect and enhance the surface performance of the roller portion 31, that is, the above-mentioned arrangement can avoid direct contact between the roller portion 31 and the fabric, reduce the wear on the roller portion 31, and the rotation of the roller 33 is stronger than that of the roller portion 31, thereby improving the uniform distribution of the liquid on the fabric and the stability of the fabric when passing through.

[0055] According to some embodiments of the utility model, the second roller 30 further includes: a limit block 322, the limit block 322 is constructed as two and is respectively arranged on the two connecting parts 32, the limit block 322 protrudes from the connecting part 32 in the radial direction, and the two limit blocks 322 cooperate to limit the axial movement of the roller 33. It can be understood that the limit blocks 322 are respectively arranged on the two connecting parts 32, and the limit blocks 322 are suitable for stopping with the roller 33 when the roller 33 has an axial movement relative to the roller part 31, thereby preventing the roller 33 from moving in the axial direction relative to the roller part 31, improving the setting stability of the roller 33, and thus improving the working stability of the second roller 30.
