[0032] Embodiment 1:

[0033] like Figure 1-Figure 3 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 driving device 40, 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 can selectively move toward the first roller 20 and contact the first roller 20, the driving device 40 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 toward or away from the first roller 20.

[0034] 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 first mounting holes facing each other, and the two ends of the first roller 20 in the axial direction are respectively rotatably provided in the first mounting holes. The driving device 40 is connected to the base 11 and / or the support seat 12. The driving end of the driving device 40 is connected to the second roller 30 and is suitable for driving the second roller 30 to move toward or away from the first roller 20.

[0035] It is worth noting that the driving device 40 is arranged outside the working space, and the two ends of the second roller 30 extend outside the working space respectively, and the two support seats 12 are respectively provided with first sliding holes 121 facing each other, and the second roller 30 can move along the extension direction of the first sliding holes 121. Therefore, the above arrangement can avoid interference between the driving device 40 and the first roller 20, thereby ensuring the normal operation of the liquid blocking roller assembly 1. At the same time, the above arrangement can also avoid contact between the liquid at the squeezed part on the fabric and the driving device 40, so that the driving device 40 can work normally, and can avoid corrosion of the driving device 40 by the liquid, thereby extending the service life of the driving device 40.

[0036] It is understandable 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 first roller 20 and the second roller 30 cooperate and squeeze the dyed fabric, thereby intercepting excess liquid on the fabric. The driving device 40 can drive the second roller 30 to move toward or away from the first roller 20, that is, when the fabric is ready to enter between the first roller 20 and the second roller 30, the driving device 40 can work to move the driving end, and the driving end moves to move the second roller 30 away from the first roller 20, so that the fabric can smoothly enter between the first roller 20 and the second roller 30, avoiding the fabric from overcoming the gravity of the second roller 30 when entering between the first roller 20 and the second roller 30, improving the smoothness between the first roller 20 and the second roller 30 of the fabric, thereby improving the production efficiency of the fabric.

[0037] When at least part of the fabric is located between the first roller 20 and the second roller 30, the driving device 40 can work to move the driving end, and the movement of the driving end can move the second roller 30 toward the first roller 20, thereby controlling the pressure of the first roller 20 and the second roller 30 on the fabric, thereby controlling the interception effect of excess liquid on the fabric. It is worth noting that the amount of liquid remaining on the fabric will affect the dyeing effect of the fabric, and thus, the dyeing effect of the fabric can be controlled through the above settings.

[0038] According to the liquid intercepting roller assembly 1 for fabric dyeing of the utility model, a driving device 40 is arranged on the frame 10, and the driving end of the driving device 40 is connected to the second roller 30. The driving device 40 can drive the second roller 30 to move toward or away from the first roller 20 through the driving end. The second roller 30 moves toward or away from the first roller 20 to control the squeezing force on the fabric, thereby achieving the effect of controlling the interception of excess liquid on the fabric, and at the same time, it can achieve the control of the dyeing effect of the fabric, improve the dyeing diversity of the fabric, and thus expand the process range of fabric production.

[0039] It is worth mentioning that the liquid-blocking roller assembly 1 of the present application can prevent the operator from manually lifting the second roller 30, thereby reducing the operator's workload; and the driving device 40 works to lift the second roller 30, compared to the operator manually lifting the second roller 30, which can prevent 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 prevent the operator from contacting the dye (the dye is corrosive), thereby preventing the dye from affecting the operator's safety.

[0040] At the same time, 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 causing the fabric movement speed to slow down or even stop, and then causing the fabric to get stuck during the production process.

[0041] 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 driving device 40 to work and move the second roller 30 away from the first roller 20, so that the wool accumulated at the joint place between 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 driving device 40 is controlled to work and the second roller 30 is stopped against the fabric, thereby avoiding the fabric from getting stuck during the production process and improving the production efficiency of the fabric.

[0042] Embodiment 2:

[0043] In this embodiment, based on the first embodiment, the driving device 40 includes: a connecting rod 41 and a first driving member 42, one end of the connecting rod 41 is rotatably connected to the frame 10, the other end of the connecting rod 41 is rotatably connected to the second roller 30, the first driving member 42 is connected to the frame 10, and the first driving member 42 has a first output end, and the first output end is connected to the connecting rod 41.

[0044] In some embodiments, the connecting rod 41 is configured as the driving end, and the two ends of the connecting rod 41 are respectively provided with a first rotating portion and a second rotating portion, and the first rotating portion is suitable for being rotatably connected with the second roller 30. At this time, the first sliding hole 121 extends circumferentially with the center of the second rotating portion. Here, the first rotating portion can be configured as a first rotating hole, and the second roller 30 can be rotatably inserted into the first rotating hole; or the first rotating portion can be configured as a second rotating rod extending in the axial direction, and the second roller 30 is provided with a second rotating hole extending in the axial direction, and the second rotating rod can be rotatably received in the second rotating hole, which is not limited here. Similarly, the second rotating portion can be configured as a third rotating hole or a third rotating rod, and it is sufficient to ensure that the two ends of the connecting rod 41 are rotatably connected with the second roller 30 and the frame 10, respectively, which is not limited here.

[0045] It can be understood that the second roller 30 rotates with the second rotating part as the center, and the second roller 30 rotates to move toward or away from the first roller 20, thereby controlling the distance between the first roller 20 and the second roller 30, and further controlling the pressure of the first roller 20 and the second roller 30 on the fabric.

[0046] Compared with the second roller 30 simply moving linearly toward or away from the first roller 20, the second roller 30 rotates in the circumferential direction. The path traveled by the second roller 30 approaching the first roller 20 is longer, so that the distance between the second roller 30 and the first roller 20 can change more slowly, thereby making the pressure control of the first roller 20 and the second roller 30 on the fabric more precise.

[0047] Embodiment three:

[0048] In this embodiment, based on the second embodiment, the first output end can selectively move toward or away from the first driving member 42, and the first output end is rotatably and movably connected to the connecting rod 41. It can be understood that the first driving member 42 can be constructed as a cylinder, a linear motor, a hydraulic cylinder, etc., as long as the first output end can move toward or away from the first driving member 42, and no limitation is made here.

[0049] The first driving member 42 is arranged on the frame 10, and the first output end is rotatably and movably connected to the connecting rod 41. Here, the first output end can be connected to any position between the first rotating part and the second rotating part of the connecting rod 41, and there is no limitation here. For example, a second sliding hole 411 is arranged between the connecting rods 41, and the extension direction of the second sliding hole 411 is parallel to the extension direction of the connecting rod 41. The free end of the first output end is provided with a sliding rod, and the sliding rod is movably and rotatably arranged in the second sliding hole 411.

[0050] Through the above arrangement, the present application can convert the linear movement of the first output end into the circumferential rotation of the second roller 30, so that the second roller 30 can rotate circumferentially with the center of the second rotating part, and then the second roller 30 can selectively move toward or away from the first roller 20.

[0051] Embodiment 4:

[0052] In this embodiment, on the basis of the second embodiment, the first output end can rotate relative to the first driving member 42, and the first output end is fixedly connected to the connecting rod 41. It can be understood that the first driving member 42 can be constructed as a rotating motor, etc., as long as the first output end can rotate relative to the first driving member 42, and no limitation is made here. At this time, the first driving member 42 is connected to the frame 10, and the first output end of the first driving member 42 is fixedly connected to the second rotating part of the connecting rod 41. The operation of the first driving member 42 can rotate the first output end, and the rotation of the first output end can drive the second rotating part to rotate. At this time, the connecting rod 41 rotates around the second rotating part, and at the same time, the second roller 30 follows the connecting rod 41 to rotate around the second rotating part.

[0053] Embodiment five:

[0054] In this embodiment, based on the first embodiment, the driving device 40 includes: a second driving member having a second output end that can selectively move toward or away from the second driving member, and the second output end is connected to the second roller 30 .

[0055] In some embodiments, the second driving member can be constructed as a linear motor, a cylinder or a hydraulic cylinder, etc., as long as the second output end can be oriented toward or away from the second driving member, and there is no limitation here. The second output end is rotatably connected to the second roller 30. At this time, the second output end, the second roller 30, and the first roller 20 are located in the same plane. When the second driving member is working, the second output end can move toward or away from itself, and the second driving end moves and drives the second roller 30 to move toward or away from the first roller 20, thereby controlling the distance between the first roller 20 and the second roller 30, and further controlling the pressure of the first roller 20 and the second roller 30 on the fabric.

[0056] Embodiment six:

[0057] In this embodiment, on the basis of the first embodiment, the outer periphery of the first roller 20 and / or the second roller 30 is provided with a roller 31.

[0059] According to some embodiments of the utility model, the first roller 20 and / or the second roller 30 are respectively provided with limit blocks 32 at both ends in the axial direction, and the limit blocks 32 are suitable for limiting the axial movement of the roller 31 relative to the first roller 20 and / or the second roller 30. It can be understood that the limit blocks 32 are suitable for abutting against the roller 31 when the roller 31 moves in the axial direction relative to the first roller 20 or the second roller 30, thereby preventing the roller 31 from moving in the axial direction relative to the first roller 20 or the second roller 30, improving the setting stability of the roller 31, and thus improving the working stability of the liquid blocking roller assembly 1.

[0060] According to some embodiments of the utility model, the liquid blocking roller assembly 1 further includes: a pressure sensor, which is disposed on the first roller 20 and / or the second roller 30, and is suitable for monitoring the pressure between the first roller 20 and the second roller 30. It can be understood that the pressure sensor can monitor the pressure between the first roller 20 and the second roller 30 in real time, and the operator can control the distance between the first roller 20 and the second roller 30 according to the value displayed by the pressure sensor, so as to achieve accurate control of the squeezing force of the first roller 20 and the second roller 30 on the fabric.

[0061] Preferably, the pressure sensor is electrically connected to the driving device 40, whereby the pressure sensor can control the operation of the driving device 40 in real time according to the pressure between the first roller 20 and the second roller 30, thereby achieving real-time control of the squeezing force of the first roller 20 and the second roller 30 on the fabric, thereby ensuring that the fabric is subjected to the same squeezing force during the production process, that is, the above-mentioned arrangement can ensure that the amount of liquid intercepted by the fabric is the same when the fabric passes through the liquid intercepting roller assembly 1, thereby ensuring the dyeing consistency of the fabric.
