The required material of the thermoplastic plate is softened after being heated one by one, and the softened material is mixed after being sent into the fluid fusion frame 1. The mixed material can complete the preliminary shaping and be discharged from the fluid fusion frame 1. For details of the step of transmitting the material into the fluid fusion frame 1, please refer to the Chinese patent with the authorization announcement No. CN207617068U, a thermoplastic pull rod box plate extrusion forming device, which is described in detail in the application.

[0027] Among them, the transmission roller 2 for transmitting the thermoplastic plate is uniformly distributed on one side of the fluid fusion frame 1. The heat dissipation structure 17 is arranged between the adjacent two transmission rollers 2. The heat dissipation structure 17 is used for active cooling at intervals through the transmission roller 2. The high-pressure gas mist is transmitted into the heat dissipation structure 17 to complete the contact with the high-temperature thermoplastic plate, and the cooling is completed after the contact.

[0028] In order to avoid the uneven heat dissipation caused by the transmission of high-pressure mist from one side edge to the other side edge, as shown in Figure 3 As shown, the heat dissipation structure 17 is composed of a first heat dissipation frame 8, a second heat dissipation frame 9, a third heat dissipation frame 10, a fourth heat dissipation frame 11, a shunt pipe 15, a first connecting ring 16 and a shunt piece 19. The first heat dissipation frame 8, the second heat dissipation frame 9, the third heat dissipation frame 10 and the fourth heat dissipation frame 11 are arranged in sequence. The shunt pipe 15 is provided with four pairs. The four pairs of shunt pipes 15 are respectively located at the lower ends of the first heat dissipation frame 8, the second heat dissipation frame 9, the third heat dissipation frame 10 and the fourth heat dissipation frame 11. Each pair of shunt pipes 15 corresponds to a first heat dissipation frame 8, a second heat dissipation frame 9, a third heat dissipation frame 10 and a fourth heat dissipation frame 11. One shunt pipe 15 is used for receiving the transmitted high-pressure gas mist, and the other shunt pipe 15 is used for discharging the high-pressure gas mist after heat dissipation.

[0029] Among them, the shunt piece 19 is transversely distributed with four shunt pieces 19. The shunt piece 19 is located between a pair of shunt pipes 15. The shunt piece 19 is located in the middle of the first heat dissipation frame 8, the second heat dissipation frame 9, the third heat dissipation frame 10 and the fourth heat dissipation frame 11. Through the shunt of the shunt piece 19, a pair of shunt pipes 15 can complete the input and output of the high-pressure gas mist. The shunt piece 19 and the shunt pipe 15 provide and give the high-pressure gas mist a stable and efficient flow trajectory, so that the high-pressure gas mist can stably and efficiently contact the thermoplastic plate in the transmission process. The first heat dissipation frame 8, the second heat dissipation frame 9, the third heat dissipation frame 10 and the fourth heat dissipation frame 11 are welded and fixed with the corresponding shunt piece 19.

[0030] In addition, two first connecting rings 16 are transversely arranged, and one of the two first connecting rings 16 is sealingly connected with the mutually close split flow pipes 15 at the lower ends of the first heat dissipation frame 8 and the second heat dissipation frame 9, and the other first connecting ring 16 is sealingly connected with the mutually close split flow pipes 15 at the lower ends of the third heat dissipation frame 10 and the fourth heat dissipation frame 11.

The lower ends of the split flow pipes 15 on both sides of the heat dissipation structure 17 are provided with first connecting fasteners 12, and the lower end of the second connecting ring 20 is provided with a second connecting fastener 13. The second connecting fastener 13 and the first connecting fastener 12 are sealingly connected through an exhaust pipe 7. The discharged high-pressure gas mist is uniformly discharged from the position of the exhaust pipe 7, which is convenient for the recovery of high-pressure gas mist.

The lower ends of the two connecting pipes 14 are sealingly connected through an air inlet pipe 6. Through the air inlet pipe 6, the high-pressure gas mist required for heat dissipation can be directly transmitted into the heat dissipation structure 17, and through flow guiding and splitting, it can be simultaneously fed into the first heat dissipation frame 8, the second heat dissipation frame 9, the third heat dissipation frame 10 and the fourth heat dissipation frame 11 to complete the cooling of the plate.

[0033] In order to avoid the adhesion of the high-temperature thermoplastic plate to the transmission roller 2 when the high-temperature thermoplastic plate contacts the transmission roller 2, as shown in Figure 2 , a support 18 is arranged between the transmission roller 2 and the fluid fusion frame 1. The upper and lower ends of the side of the support 18 facing the fluid fusion frame 1 are transversely provided with liquid transmission pipes 4. The two liquid transmission pipes 4 are provided with spray heads 5 towards the middle position of the support 18. Fluorine release agent transmitted into the liquid transmission pipe 4 is sprayed from the spray head 5 and contacts the high-temperature thermoplastic plate to avoid adhesion.

[0034] Two liquid transmission pipes 4 are sealed on one side by a pump 3, and the pump 3 can extract fluorine release agent reserved in the water tank, so as to complete the transmission and discharge of the fluorine release agent.

[0035] Working principle: when the device is used to cool and form the thermoplastic plate, the mixed material of the thermoplastic plate is heated and softened and uniformly sent into the fluid fusion frame 1, and the material is mixed and preliminarily formed into a long strip-shaped thermoplastic plate in the fluid fusion frame 1, when the material discharged from the fluid fusion frame 1 passes through a pair of liquid transmission pipes 4, the pump 3 is started, the pump 3 extracts fluorine release agent and sprays it from the spray head 5, the long strip-shaped thermoplastic plate is continuously transmitted and contacts the transmission roller 2, the transmission roller 2 supports the thermoplastic plate without cooling, high-pressure gas mist is extracted and sent into the heat dissipation structure 17 from the air inlet pipe 6, the high-pressure gas mist is transmitted into the first connecting ring 16 after being divided by a pair of connecting pipes 14, the high-pressure gas mist in one of the first connecting rings 16 is transmitted into the first heat dissipation frame 8 and the second heat dissipation frame 9 and is divided by the dividing piece 19, and the high-pressure gas mist in the other first connecting ring 16 is transmitted into the third heat dissipation frame 10 and the fourth heat dissipation frame 11 and is divided by the dividing piece 19, the high-pressure gas mist divided in the first heat dissipation frame 8 and the fourth heat dissipation frame 11 is transmitted from the first connecting pipe 12 to the exhaust pipe 7, and the high-pressure gas mist divided in the second heat dissipation frame 9 and the third heat dissipation frame 10 is transmitted from the second connecting pipe 13 to the exhaust pipe 7, and the high-pressure gas mist after absorbing heat and cooling the plate is uniformly discharged from the exhaust pipe 7.
