[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1-2As shown, this embodiment discloses a sheet cold pressing device, including a lifting platform 5, which is a long strip block structure. A baffle 4 is slidably connected to the outer wall of the lifting platform 5. The baffle 4 is a long strip plate structure, located on both sides of the lifting platform 5. The lifting platform 5 can move up and down along the inner wall of the baffle 4. A support base 41 is installed at the bottom of the baffle 4. Multiple rods 42 are installed on the support base 41, and multiple rods 42 are arranged along the length direction of the support base 41. Springs 43 are sleeved on the rods 42. Springs 43 are installed on the upper end of the support base 41. The upper end of the springs 43 abuts against the lifting platform 5, and the lower end of the springs 43 abuts against the support base 41.

[0021] The bottom of the lifting platform 5 passes through the support base 41, and a base 8 is fixedly installed on the bottom of the lifting platform 5. The base 8 can move up and down to drive the lifting platform 5 to move synchronously. Specifically, a bracket plate 6 is installed on the bottom of the support base 41. Two bracket plates 6 are arranged opposite each other on the left and right sides. A shaft 62 is installed between the two bracket plates 6. The two ends of the shaft 62 are inserted into the bracket plates 6, and the two are connected by bearings 61. The shaft 62 is connected to a gear pair 622, which is driven by a motor 623 so that the shaft 62 can rotate along its own axis. The base 8 has a through groove 81, through which the shaft 62 passes. A cam 621 is installed on the shaft 62. When the long shaft end of the cam 621 rotates, it can push the upper wall of the bottom of the base 8 to move the base 8 downward, thereby driving the lifting platform 5 to move synchronously.

[0022] like Figure 1 , Figure 3 As shown, the lifting platform 5 includes protrusions 51 on both sides. Protrusions 51 are elongated structures, extending upwards along the upper surface of the lifting platform 5. Each protrusion 51 includes an extension platform 511 at its upper end, which extends upwards along the upper surface of the protrusion 51 to form an elongated structure. Figure 3 As shown, the extension platform 511 is provided with a groove 5111, which is located at the bottom of the extension platform 511 and extends through one side wall of the extension platform 511.

[0023] like Figures 1-3 As shown, the extension platform 511 can hold the sheet body 7. The lower wall of the sheet body 7 is in contact with the upper wall of the extension platform 511. The sheet body 7 is provided with a second boss 71, and the second boss 71 is provided with an extension platform 711, which is inserted into a groove 5111. The sheet body 7 can be transported along the length of the lifting platform 5. The lifting platform 5 is provided with a groove 52, which is located between the two bosses 51 to reduce the resistance to the transmission movement of the sheet body 7.

[0024] like Figure 1As shown, it also includes a fixing plate 1, on which a bladder 3 is installed. The bladder 3 has a cavity 32, through which coolant flows. The fixing plate 1 is equipped with two connecting pipes 11, which are connected to the cavity 32. Coolant is introduced into and out of the cavity 32 through the connecting pipes 11.

[0025] like Figure 1 , Figure 3 As shown, the lifting platform 5 is located below the bladder 3. The bladder cavity 32 includes a wall 33 at the bottom. The wall 33 is made of elastic material. When the bladder cavity 32 is filled with liquid, the wall 33 hangs down, and the upper wall of the sheet body 7 can be attached to the bottom surface of the wall 33 so that the wall 33 can cool the upper wall of the sheet body 7. A thin film is also attached to the upper wall of the sheet body 7. The pressure formed by the wall 33 on the upper wall of the sheet body 7 prevents the film from shrinking and producing raised textures during the cooling process, thereby improving the surface quality.

[0026] A pressure plate 2 is installed on the upper end of the fixing plate 1, and the bladder 3 is provided with a connecting part 31. The fixing plate 1 and the pressure plate 2 are pressed together with the connecting part 31 to fix the bladder 3.
