TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field, concretely is a plaster production punching equipment. BACKGROUND

[0002] In the production process of the drug patch, the patch needs to be punched. The patch punching device mainly consists of an upper die plate, a lower die plate and a punching needle. The punching needle is fixed on the upper die plate. The lower die plate is provided with a circular hole, and the diameter of the circular hole is slightly larger than the outer diameter of the punching needle. The position of the circular hole corresponds to the position of the punching needle. When punching, the patch to be punched is placed on the lower die plate, and the upper die plate moves from top to bottom towards the lower die plate, so that the punching needle penetrates through the circular hole of the lower die plate and pierces the patch at the same time.
