[0038] Optionally, the movable bearing seat 42 and the fixed bearing seat 32 are respectively slidably connected to the parallel slide rails 16. Two slide rails 16 are provided, and the movable bearing seat 42 and the fixed bearing seat 32 are respectively slid on the corresponding slide rails 16 to achieve respective adjustment with less mutual interference.

[0039] Further preferably, the frame 10 is installed with a ruler 17, and the ruler 17 is arranged corresponding to the slide rail 16, so that the distance between the fixed roller 31 and the movable roller 41 can be indicated by the ruler 17, so as to facilitate the adjustment of the squeeze space size.

[0040] like Figures 1 to 5 As shown, both the fixed roller 31 and the movable roller 41 include a roller body, and the roller body is used to squeeze the surface of the strip steel 70. The roller body includes a squeezing stem 311, a rotating shaft 312 protruding from both ends of the squeezing stem 311, and a water retaining ring 313 protruding radially along the rotating shaft 312, and at least one water retaining ring 313 is provided on the rotating shaft 312 at each end.

The water retaining ring 313 and the squeezing stem 311 are arranged at intervals to form a water retaining space.

[0041] The fixed roller 31 and the movable roller 41 are arranged in parallel, and the structures of the two are basically the same. Further preferably, the water retaining ring 313 of the movable roller 41 and the water retaining ring 313 of the fixed roller 31 are arranged in a staggered manner to form a cross-blocking effect of water flow. Wherein, the cross-arrangement includes: the water retaining ring 313 of the movable roller 41 is located between the water retaining ring 313 of the fixed roller 31 and the extrusion pipe 311; or, the water retaining ring 313 of the fixed roller 31 is located between the water retaining ring 313 of the movable roller 41 and the extrusion pipe 311. Further preferably, two water retaining rings 313 are arranged on the rotating shaft 312 at each end, and the water retaining ring 313 of the movable roller 41 and the water retaining ring 313 of the fixed roller 31 are arranged alternately and staggered.

[0042] In a preferred embodiment, the squeezing device further includes a water retaining plate 60 movably mounted on the frame 10, and the water retaining plate 60 is located between the movable bearing seat 42 and the water retaining ring 313. The water retaining plate 60 is inserted into the housing 11 to form a two-way barrier mechanism, thereby preventing the liquid from further diffusing into the internal space of the housing 11, and facilitating the liquid to gather in the water diversion groove 15.

[0043] The fixed roller 31 and the movable roller 41 are respectively attached to the surface of the steel strip 70 to squeeze out the liquid on the surface of the steel strip 70. Optionally, the fixed roller 31 and the movable roller 41 are configured as rigid rollers with smooth cylindrical surfaces. In order to reduce the wear between the fixed roller 31 and the movable roller 41 and the surface of the steel strip 70 or damage to the surface of the steel strip 70, the surface of the fixed roller 31 and / or the movable roller 41 is compounded with an elastic rubber layer 314 so that the wear is concentrated on the elastic rubber layer 314 and the surface of the steel strip 70 is avoided. Specifically, the surface of the fixed roller 31 is compounded with an elastic rubber layer 314; and / or the surface of the movable roller 41 is compounded with an elastic rubber layer 314.

[0044] During the operation of the continuous production line of the steel strip 70, friction occurs between the steel strip 70 and the elastic rubber layer 314 of the fixed roller 31 and / or the movable roller 41, which gradually thins the elastic rubber layer 314. The fixed roller 31 is kept in position by adjusting the lead screw 33, and the telescopic assembly 50 controls the movable roller 41 to move forward, so that the fixed roller 31 and the movable roller 41 are always squeezed with the steel strip 70 to ensure the squeezing efficiency.

The limit rod 12 and the slide rail 16 respectively limit the upper and lower ends of the fixed bearing seat 32 to form a clamping limit structure. Preferably, the fixed bearing seat 32 is provided with a mounting groove and a positioning groove located at the top from the top downward, one end of the fixed roller 31 is buckled into the mounting groove, and the limit rod 12 is buckled into the positioning groove and limits the fixed roller 31 in the mounting groove. Based on the same principle, one end of the movable roller 41 is assembled on the movable bearing seat 42 to facilitate disassembly and replacement.

[0046] When the elastic rubber layer 314 is worn to the point of being unusable; or when the fixed roller 31 or the movable roller 41 is damaged, the telescopic assembly 50 drives the movable roller 41 to move backward, and by replacing the movable roller 41 or the fixed roller 31 and realizing rapid roller change, the production efficiency of the continuous production line of the strip steel 70 is improved.

[0047] Furthermore, the two opposite side walls of the frame 10 are provided with a long hole 14 and a locking frame 13 detachably mounted on the side wall, the length direction of the long hole 14 intersects with the length direction of the slide rail 16, the limit rod 12 is limited in the long hole 14, and the locking frame 13 locks the limit rod 12. The locking frame 13 is detachably connected, thereby releasing the limit rod 12, and the limit rod 12 can slide along the long hole 14 and away from the fixed bearing seat 32 and the movable bearing seat 42, so as to improve the replacement efficiency of the fixed roller 31 or the movable roller 41 during the disassembly and assembly operation.
