[0041] See also Figures 1 to 7 , this embodiment includes:

[0042] The blister machine body 1 utilizes the vacuum suction force generated by the vacuum pump to blister the heated and softened thermoplastic plastic sheets such as PVC and PET into products of various shapes through a mold. A blocking plate 2 for blocking is provided at the top of the blister machine body 1. A cooling component 3 is provided at the periphery of the blister machine body 1. A plurality of connecting blocks 4 are installed at the periphery of the cooling component 3. The size of the connecting block 4 ensures that it does not affect the linear motor 9. A vertical electric push rod 5 is fixedly connected to the periphery of the connecting block 4.

The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0055] How it works

[0056] The automatic blister forming machine places the plastic raw material between the blister forming machine body 1 and the blocking plate 2, controls the vertical electric push rod 5 to contract, so that the blocking plate 2 is blocked, and turns on the exhaust device 61 to exhaust the blister forming. After the blister forming is completed, the semiconductor refrigeration sheet 33 is turned on for cooling and cooling, and the fan 37 is turned on for ventilation. With the help of the vent pipe 38, the air in the insulation shell 31 can form a flowing state to improve the temperature uniformity. When it is necessary to unload the material, the vertical electric push rod 5 is slightly extended to release the blocking of the blocking plate 2, and the forward and reverse motors are turned on. 8 drives the rotating shaft to rotate, and indirectly drives the blister machine body 1 to rotate, so that the opening of the blister machine body 1 faces downward, and the plastic product can fall with gravity. If the material has not been unloaded, the servo motor 15 drives the rotating rod 16 to rotate, and then drives the eccentric wheel 17 to rotate, so that the eccentric wheel 17 indirectly hits the blister machine body 1 to assist in unloading the plastic product. When unloading is required, the extension of the vertical electric push rod 5 can push open the sealing plate 2, and the linear motor 9 drives the push plate 10 to move to push the plastic product off the sealing plate 2.
