[0032] Sealing assembly 3 is arranged at the connecting position of fixed groove body 11 and movable groove body 12 and is used for sealing the connecting position of fixed groove body 11 and movable groove body 12.

[0033] The utility model discloses, fixed groove body 11 and movable groove body 12 constitute the groove body 1, utilize drive mechanism 2 drive movable groove body 12 and move to adjust the length of groove body 1, and the sealing assembly 3 is sealed to the fixed groove body 11 and movable groove body 12 junction, so that the cooling water tank can correspond to the length adjustment after the extrusion speed changes, to ensure that the different conveying speed's material strip can be cooled completely, and simultaneously will not cause unnecessary space occupation.

[0034] In an embodiment, the fixed groove body 11 includes a first sink 111, and the bottom of one end of the first sink 111 in the length direction is provided with at least two first legs 112 for connecting with the ground. The fixed groove body 11 further includes at least two second legs 113 for connecting with the ground, and the second legs 113 are located at the bottom of the other end of the first sink 111 in the length direction. The top of the second legs 113 is provided with a first load-bearing roller 114 for supporting the movable groove body 12.

[0035] The movable groove body 12 includes a second sink 121 which is sleeved on the first sink 111 and communicates with the first sink 111. The first load-bearing roller 114 abuts against the bottom of the second sink 121. The bottom of one end of the second sink 121 away from the first sink 111 is provided with at least two rolling legs 122. The rolling legs 122 are provided with rollers which abut against the ground.

[0036] In this way, the first sink 111 will not move randomly due to the connection of the first legs 112 with the ground. The second sink 121 can reduce the frictional resistance between the second sink 121 and the ground when moving due to the action of the rolling legs 122 and the rollers, thereby ensuring smoothness of adjustment. The second sink 121 away from the rolling legs 122 can be supported by the second legs 113, thereby improving the installation stability of the cooling water tank. The first load-bearing roller 114 can reduce the wear between the first load-bearing roller 114 and the second sink 121 due to the rolling contact between the first load-bearing roller 114 and the second sink 121.

[0037] In an embodiment, the drive mechanism 2 includes a linear module 21. The linear module 21 is provided with a sliding plate 22 which can be driven by the linear module 21 to move along the length direction of the first sink 111. The end of the sliding plate 22 away from the linear module 21 is fixedly connected with the bottom of the second sink 121. The linear module 21 is arranged between the first legs 112 and the second legs 113.

[0038] In this way, the sliding plate 22 is driven to move by the linear module 21, and the second sink 121 connected with the sliding plate 22 is further driven to move.

[0039] It should be noted that the motor transmission shaft of the straight line module 21 is provided with an electromagnetic brake for locking the output shaft. The electromagnetic brake prevents the output shaft from rotating, ensuring that the adjusted length of the cooling water tank cannot be changed arbitrarily.

[0040] In an embodiment, the sealing assembly 3 includes a sealing member 31 for sealing the connection between the fixed tank body 11 and the movable tank body 12, and a tightness control member 32 for controlling the tightness of the sealing member 31.

[0041] The sealing member 31 includes a U-shaped sealing strip 311. The first water tank 111 has a U-shaped groove at one end inside the second water tank 121 for installing the U-shaped sealing strip 311. The U-shaped sealing strip 311 is movably arranged in the U-shaped groove. The U-shaped sealing strip 311 is provided with a plurality of guide columns 313 inserted into the first water tank 111. The first water tank 111 has a slope groove that guides the guide columns 313 to move towards one side of the U-shaped sealing strip 311. The sealing member 31 further includes a U-shaped blocking plate 314 detachably arranged on one end of the first water tank 111 inside the second water tank 121. The U-shaped blocking plate 314 is used to prevent the U-shaped sealing strip 311 and the U-shaped sealing strip 312 from moving out of the U-shaped groove.

[0042] The tightness control member 32 includes a fixed seat arranged on the first water tank 111. The fixed seat is provided with a screw rod and at least one positioning column on the top. The fixed seat is provided with a pressing plate sleeved with the screw rod and the positioning column. The screw rod is threadedly connected with a nut located on the top of the pressing plate. The bottom of the pressing plate abuts against the top of the U-shaped sealing strip 312.

[0043] In this way, by rotating the nut, the nut moves downward, pushing the pressing plate downward, and extruding the U-shaped sealing strip 312. Due to the action of the guide column 313 and the slope groove, the U-shaped sealing strip 312 moves towards the side close to the U-shaped sealing strip 311. By extruding the U-shaped sealing strip 311, the U-shaped sealing strip 311 deforms and tightly abuts against the connection between the fixed tank body 11 and the movable tank body 12, completing the sealing and blocking of the connection, ensuring that the cooling water tank can be sealed after being adjusted to any length, and preventing water leakage during use.

[0044] It should be noted that when the length of the cooling water tank needs to be adjusted, the nut can be loosened first, so that the U-shaped sealing strip 312 no longer extrudes the U-shaped sealing strip 311, thereby reducing the frictional resistance between the second water tank 121 and the U-shaped sealing strip 311 when moving, and reducing the wear of the U-shaped sealing strip 311.

[0045] In an embodiment, the first water tank 111 is provided with at least one second load-bearing roller 4 for rolling and walking on the top of the second water tank 121.

[0046] In this way, the second water tank 121 can support the first water tank 111 through the second load-bearing roller 4, so that the wear of the first water tank 111 and the second water tank 121 during movement can be further reduced, and the installation stability can be improved.
