The support frame 2 is fixed on the inner wall of the cold water tank 1 and is immersed in the cold water. On the bottom wall of the shaping frame 3 and the top wall of the support frame 2, a number of support wheels 4 are arranged side by side along the length direction of the cold water tank 1. In the embodiment of the present application, each support wheel 4 includes two support rollers 41 and one model roller 42. Two first support pipes are coaxially connected to both ends of the model roller 42. The ends of the two support rollers 41 far from the model roller 42 are rotatably connected to the support frame 2 / the shaping frame 3 respectively. The two ends of the model roller 42 are detachably connected to the two support rollers 41 respectively. On the outer wall of the model roller 42, a mold base adapted to the shape of the edge sealing strip is arranged along its circumferential direction. The edge sealing strip passes through between the support frame 2 and the shaping frame 3 in the cold water tank 1. The model roller 42 on the support frame 2 and the model roller 42 on the shaping frame 3 respectively fit the bottom wall and the top wall of the edge sealing strip. According to the shape of the edge sealing strip, the cross-sectional shape of the mold base of the model roller 42 on the support frame 2 and the cross-sectional shape of the mold base of the model roller 42 on the shaping frame 3 respectively adapt to the cross-sectional shape of the bottom wall and the cross-sectional shape of the top wall of the edge sealing strip. A driving assembly for driving the support roller 41 to rotate is also arranged on the cold water tank 1. During the process of the edge sealing strip passing through the cold water tank 1, the driving assembly drives the support wheels 4 on the support frame 2 and the shaping frame 3 to rotate synchronously in the reverse direction. During the process of conveying the edge sealing strip forward, the model wheels on the support frame 2 and the model wheels on the shaping frame 3 are also used to support the bottom wall structure and the top wall structure of the edge sealing strip respectively, ensuring that the overall shape of the edge sealing strip is supported during the process of passing through the cold water tank 1, avoiding the distortion of the edge sealing strip structure, and improving the cooling and shaping quality of the edge sealing strip.

[0022] Specifically, the driving assembly includes a first driving motor 5. The support rollers 41 adjacent to each other on the same side of the support frame 2 and the shaping frame 3 are connected by belt transmission. The first driving motor 5 is simultaneously connected to any one support roller 41 on the support frame 2 and any one support roller 41 on the shaping frame 3 by transmission, so that the support rollers 41 on the support frame 2 and the support rollers 41 on the shaping frame 3 rotate synchronously in the reverse direction. The belt can be a wedge-shaped conveyor belt to keep each support wheel 4 rotating synchronously. A transmission wheel is rotatably installed on the support frame 2. The output shaft of the first driving motor 5 is connected to the transmission wheel on the support frame 2 and the support roller 41 on the shaping frame 3 by belt transmission, and then connected to the support roller 41 on the support frame 2 by belt transmission through the transmission wheel, so that the support rollers 41 on the support frame 2 and the support rollers 41 on the shaping frame 3 rotate in the reverse direction.

[0023] Refer to Figure 4, in the embodiment of the present application, one end of the supporting roller 41 is rotatably connected to the supporting frame 2 / forming frame 3, and a positioning block 6 is integrally fixed to the other end.
