[0002] Pharmaceutical packaging is crucial for maintaining its performance. Currently, pharmaceuticals such as capsules, tablets, and pills are commonly packaged in aluminum-plastic blister packaging, which offers excellent sealing properties and is convenient to carry, transport, sell, and use. The aluminum-plastic blister packaging machine consists of a PVC film forming unit, a feeding unit, a heat-sealing unit, a travel traction unit, and a punching unit. During the packaging process, the blister is heat-sealed with aluminum-plastic sheeting after being filled with the drug. Traditionally, a lifting and hot-pressing device has been installed on a linearly conveyed blister belt. Each section of the belt must stop before the hot-pressing die descends for hot-pressing. This is highly inefficient, and the time required for lifting and lowering after hot-pressing can cause deformation of the blister before and after hot-pressing, resulting in poor molding quality.
[0003] Therefore, there is an urgent need for a simple, efficient and fast device for rolling and sealing medicine blister packaging. Utility Model Content
[0004] In view of this, the technical problem to be solved by the present invention is to provide a rolling sealing device for medicine blister packaging, which is used to avoid the trouble of using a lifting hot pressing plate for hot pressing in the past, which has low efficiency and poor molding quality.
[0005] In order to solve the above technical problems, the utility model discloses a rolling sealing device for medicine blister packaging, comprising:
[0006] Two sway support frames are arranged opposite to each other, a bearing seat is installed on the inner side of the front end of the sway support frame, and a T-shaped support is pivotally connected to the outer side of the rear end. The T-shaped support has a limit portion extending to the front end of the sway support frame, and the limit portion is provided with a height adjustment component. The height adjustment component has a compression spring that presses against the sway support frame;
[0007] A swing cylinder installed at the rear end of the swing support frame;

[0010] A cooling fan is installed at the rear side of the roller mold;
[0011] A cooling assembly mounted on the bearing housing;
[0012] The swing cylinder drives the swing support frame to rotate around the pivot joint of the T-shaped support and retracts the compression spring to make the heat sealing roller press against or away from the rolling die.
[0013] According to one embodiment of the present invention, the heat sealing roller is equipped with 6 stainless steel heating tubes.
[0014] According to one embodiment of the present invention, the surface of the heat sealing roller is engraved with patterns.
[0015] According to one embodiment of the present invention, the cooling assembly includes an outer cover shell enclosing the bearing seat, and the outer cover shell is filled with coolant.
