[0017] When the plastic sheet supporting device of the blister forming machine is actually used, the staff first installs the plastic material 2 on the positioning frame 102, and the pressure plate 201 and the fastener 202 are used to limit and fix the plastic material 2 so that the plastic material 2 is initially limited and fixed above the positioning frame 102, and then the support plate 3 below the positioning frame 102 starts to move upward, and the upward work of the support plate 3 is completed by the motors 302 on both sides and the rotors 303. The rotor 303 drives the screw rod 301 to rotate, and the support plate 3 and the screw rod 301 are threadedly connected. Driven by the screw rod 301, they slide up and down along the vertical placement until the rectangular plate 401 on the support plate 3 and the protrusion 4 on the positioning frame 102 are abutted to complete the initial positioning of the rectangular plate 401 in the positioning frame 102, and then the cylinder 305 on the support plate 3 starts to work and drives the bottom plate 304 to move upward through the slide rod 306 until the bottom plate 3 04 is in contact with the plastic material 2 to complete the support work of the plastic material 2.

The overall structure is compact and easy for the staff to install and maintain. The structure is stable and not prone to failure, thereby reducing the later maintenance cost.

[0020] Working principle: First, the staff will install the plastic material on the positioning frame, and the pressure plate and the fasteners will limit and fix the plastic material so that it is initially limited and fixed above the positioning frame. Then the support plate under the positioning frame starts to move upward. The upward movement of the support plate is driven by the motors on both sides and the rotors, and the rotor drives the screw rod to rotate. The support plate and the screw rod are threadedly connected, and driven by the screw rod, they slide up and down along the vertical placement until the rectangular plate on the support plate and the protrusion on the positioning frame are in contact with each other to complete the initial positioning of the rectangular plate in the positioning frame. Then the cylinder on the support plate starts to work and drives the bottom plate to move upward through the sliding rod until the bottom plate and the plastic material are in contact, completing the support of the plastic material. The staff can make adaptive adjustments according to the thickness of different plastic materials.
