As a specific embodiment of the present invention, one end of the connecting rope 23 far from the corresponding iron block 24 is fixed at the midpoint of the length direction of the sealing ring 16, and the connection point of the connecting rope 23 and the sealing ring 16 is located at the bottom of the side wall of the sealing ring 16, and the strip plate 12 is an elastic plate; when the device is used, the connecting rope 23 lifts the middle section of the sealing ring 16 to enable the sealing ring 16 to arch, the separation point is the middle section of the sealing ring 16, the separation point gradually diffuses towards the two ends of the sealing ring 16 in the process of separating the sealing ring 16 from the supporting block 15, and the separation speed of the sealing ring 16 and the supporting block 15 is improved; the middle section of the sealing ring 16 is provided with a rectangular groove 17, and the sealing ring 16 is easy to be pulled to deform by the tensile force of the connecting rope 23, so that the normal separation of the sealing ring 16 is ensured; the strip-shaped plate 12 is an elastic plate to ensure that the pressing block 13 can slightly deform in the process of separating the sealing ring 16 from the supporting block 15, so that the inclination angle of the separation point of the sealing ring 16 and the supporting block 15 is increased, and the separation difficulty of the sealing ring 16 and the supporting block 15 is further reduced.

As a specific embodiment of the present invention, the diameter value of the middle section of the first roller 19 is greater than the diameter values of the two ends of the first roller, the diameter value of the middle section of the second roller 20 is less than the diameter values of the two ends of the second roller, and the outer contours of the first roller 19 and the second roller 20 are matched; when the air bubble removing device is used, the bottom of the fabric may exist in the process of extruding air bubbles in the fabric, and the surface of the normal second roller 20 is parallel, so that the air bubbles are accumulated at the bottom of the fabric and cannot be discharged; the second roller 20 is thick at two ends and thin in the middle, and the first roller 19 is thick at the middle and thin at two ends, so that air bubbles are extruded into a V shape when the fabric passes through the first roller 19 and the second roller 20, and the fabric has an inclination angle; the bubbles at the fabric can move freely on the surface of the fabric, so that the bubbles can smoothly move to the top end of the reaction liquid along the surface of the fabric, and the content of the bubbles in the fabric is reduced.

When the fabric is used, the reaction liquid is not uniformly contacted with the fabric in the reaction process, and particularly the reaction liquid is prevented from entering the inner layer of the fabric under the blocking of bubbles in the fabric, so that the reaction uniformity degree of the fabric is low, and the hand feeling of the fabric is further influenced, and the problem is improved; the fabric passes through the guide roller 11 in sequence, and the free end of the fabric is fixed on the traction device, so that the fabric passes through the reaction tank 1 at a constant speed; injecting reaction liquid into the reaction tank 1, and reacting the fabric with the reaction liquid in the reaction tank 1 in the process of passing through the reaction tank 1, thereby finishing alkali decrement treatment; in the process of moving the fabric, the driving motor 3 drives the turntable to rotate, so that the connecting plate 5 makes eccentric motion, and the piston 7 makes piston 7 motion in the piston 7 cylinder 6; the piston 7 drives the pressing block 13 to reciprocate up and down in the moving process, so that the pressing block 13 is in contact with the supporting block 15 and clamps the fabric in the middle; after the pressing block 13 is contacted with the supporting block 15, a closed space is formed, the pressing block 13 continues to move downwards under the driving of the piston 7, so that the pressing block 13 is extruded and deformed, and meanwhile, the reaction liquid in the gas collecting tank 14 at the bottom of the pressing block 13 is extruded out from the interior of the fabric, so that the reaction liquid is fully contacted with the fabric; in addition, the driving motor 3 drives the rotating shaft 8 to rotate through the synchronous belt 10, so that the roller brush 9 on the rotating shaft 8 synchronously rotates; the fabric is contacted with the roller brush 9 when passing through the roller brush 9, and the roller brush 9 washes the surface of the fabric, so that the fabric is more fully and uniformly contacted with the reaction liquid; according to the invention, the pressing block 13 and the support block 15 are utilized to extrude the fabric, the pressing block 13 and the support block 15 form a closed space, and the reaction liquid enters the fabric in the extruding process, so that the fabric treatment effect is better.
