[0022] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to further illustrate the present invention.

[0023] First, combine Figure 1~2 A reeling and laminating device according to an embodiment of the utility model is described, which is used to be fixed on a printing machine to achieve reeling and laminating of aluminum-coated films, and has a wide range of application scenarios.

[0024] like Figure 1~2 As shown, an unwinding and compounding device according to an embodiment of the utility model comprises a housing 1, an air expansion shaft 2, a transmission disc 3 and a braking mechanism.

[0025] Specifically, Figure 1~2 As shown, one end of the air expansion shaft 2 can be rotatably inserted into the interior of the shell 1 to support the aluminum-coated film roll. The air expansion shaft 2 is used to facilitate the disassembly and assembly of the aluminum-coated film roll; the transmission disk 3 is fixedly sleeved on the end of the air expansion shaft 2 inserted into the interior of the shell 1; the braking mechanism is connected to the shell 1 to control the rotation of the transmission disk 3, and then indirectly control the rotation of the air expansion shaft 2.

[0026] Further, if Figure 1~2 As shown, the brake mechanism includes: a bearing 41, a driven wheel 42, a brake disc 43, a motor 44, a driving wheel 45 and a belt 46. The bearing 41 is sleeved on one end of the gas expansion shaft 2 inserted into the housing 1; the driven wheel 42 is sleeved on the bearing 41; the brake disc 43 is sleeved on one end of the gas expansion shaft 2 inserted into the housing 1, and is located between the driven wheel 42 and the transmission disc 3, the brake disc 43 is fixedly connected to the driven wheel 42, and the brake disc 43 is in contact with the transmission disc 3; the motor 44 is fixed inside the housing 1; the driving wheel 45 is sleeved on the output end of the motor 44; the belt 46 connects the driving wheel 45 and the driven wheel 42.

[0027] Further, if Figure 1As shown, an unwinding and compounding device according to an embodiment of the utility model further comprises: a mounting frame 5 , which is arranged at the bottom of the housing 1 and is used to fix the unwinding and compounding device of the present application on a printing machine 7 .
