[0030] Please refer to Figure 1 and Figure 7The movable mold fixing mechanism 6 includes a driving assembly 601, a bevel gear assembly 602, a screw assembly 603 and a T-shaped fixing column 604. The driving assembly 601 is installed on the side of the lifting seat 302, and the bevel gear assembly 602 is installed inside the lifting seat 302. The screw assembly 603 is installed on the side of the lifting seat 302 close to the bevel gear assembly 602. The bottom of the screw assembly 603 is installed with a T-shaped fixing column 604. On the threaded part of the screw assembly 603, a nut is the most common connecting component. When the screw When rotating, the nut will move along the threaded part, thereby driving the connected component T-shaped fixed column 2 604 to rise and fall. The lifting seat 302 supports the internal screw assembly 603. The screw assembly 603 is rotatably arranged inside the lifting seat 302. The screw assembly 603 is threadedly connected to the T-shaped fixed column 2 604. The driving assembly 601 is used to drive multiple bevel gear assemblies 602 to operate at the same time. The bevel gear assemblies 602 respectively drive the multiple screw assemblies 603 to rotate, and at the same time drive the multiple T-shaped fixed column 2 604 to rise and fall.

[0031] Specifically, in order to realize the molding processing of the square blister box, the cylinder 2 501 works, and its moving end will drive the lifting seat 302 to move up and down. At the same time, the driving component 601 drives multiple bevel gear components 602 to rotate, and the bevel gear component 602 drives the screw component 603 to rotate. The screw component 603 can drive the threaded driving end to drive the T-shaped fixed column 2 604 to move up and down, and then the fixed mold 401 and the movable mold 402 can be fixed by the lifting of the T-shaped fixed column 1 502 and the T-shaped fixed column 2 604. At this time, the square blister box is placed inside the fixed mold 401, and then the cylinder 1 301 works, and its moving end will drive the lifting seat 302 to move, and the lifting seat 302 can drive the movable mold 402 to move toward the surface of the fixed mold 401, so that the fixed mold 401 and the movable mold 402 can be molded together, and the internal square blister box can be curled and pressed.

[0032] Please refer to Figure 4 , Figure 6 and Figure 7 The fixed mold 401 and the movable mold 402 are both provided with guide grooves 8 on the inner side close to the T-shaped fixing column 1 502 and the T-shaped fixing column 2 604 , and the guide grooves 8 are located on the outer side of the T-shaped fixing column 1 502 and the T-shaped fixing column 2 604 .

[0033] Specifically, in order to achieve the limited installation of the fixed mold 401 and the movable mold 402, the worker slides the fixed mold 401 and the movable mold 402 so that the guide groove 8 inside the fixed mold 401 moves along the outer side of the T-shaped fixed column 502, and the guide groove 8 inside the movable mold 402 moves along the outer side of the T-shaped fixed column 604. By moving the guide groove 8 along the outer sides of the T-shaped fixed column 502 and the T-shaped fixed column 604, the fixed mold 401 and the movable mold 402 can be limited during installation.

[0034] Please refer to Figure 1 and Figure 8 The pretreatment mechanism 7 includes a vortex tube 701, a heat treatment plate 702, a cold treatment plate 703 and exhaust holes 704. The vortex tube 701 is installed on the side of the fixed seat 1, the heat treatment plate 702 is installed at one end of the vortex tube 701, and the cold treatment plate 703 is installed at the end of the vortex tube 701 away from the heat treatment plate 702. A plurality of exhaust holes 704 are equidistantly arranged inside the heat treatment plate 702 and the cold treatment plate 703.

[0035] Specifically, in order to realize the processing before and after the curling forming of the square blister box, the compressed gas will expand in the nozzle through the operation of the vortex tube 701, and then enter the interior of the vortex tube 701 along the tangential direction at a very high speed. When the airflow rotates at a high speed in the vortex tube 701, it is separated into two parts of airflow with unequal total temperatures after the vortex transformation. One end of it generates cold air and the other end generates hot air. The hot air generated by the vortex tube 701 will be transported to the heat treatment plate 702. When the hot air is vented, the hot air will be discharged to the heat treatment plate 702. When the exhaust holes 704 inside the overheating treatment plate 702 blow toward the surface of a stack of square blister boxes on the automatic loading equipment, the square blister boxes can be preheated. At the same time, when the unloading suction cup takes out the curled square blister boxes from the inside of the forming mold mechanism 4, the cold air generated inside the vortex tube 701 will be transported to the cold treatment plate 703. When the cold air is blown out from the exhaust holes 704 inside the cold treatment plate 703, the square blister boxes on the unloading suction cup that have been curled can be cooled, thereby accelerating their forming rate.

[0036] Please refer to Figure 3 and Figure 8 A temperature rod 7021 is rotatably disposed inside the heat treatment plate 702 and the cold treatment plate 703. The outer surface of the temperature rod 7021 is a thermosensitive material. The thermosensitive paint is a material that can change color according to temperature changes.

[0037] Specifically, in order to realize real-time monitoring of the temperature inside the heat treatment plate 702 and the cold treatment plate 703, and to facilitate monitoring of the staff, at low temperatures, the molecular structure or chemical properties of the thermochromic material make it mainly absorb light other than blue and reflect blue light, so it appears blue. When the temperature rises, the molecular structure or chemical properties of the material change, causing it to begin to absorb light other than red or yellow and reflect red or yellow light. When the temperature changes, the color of the temperature rod 7021 will change accordingly, thereby providing an intuitive temperature indication, which is convenient for the staff to observe and know the working status of the vortex tube 701 and the status of wind transmission inside the heat treatment plate 702 and the cold treatment plate 703.

[0038] Please refer to Figure 8An elastic ring 7041 is installed inside the exhaust hole 704, and the elastic ring 7041 is made of high-temperature resistant rubber material, specifically fluororubber.

[0039] Specifically, in order to block the exhaust hole 704 and avoid clogging of the exhaust hole 704 when not in use, thereby affecting the subsequent wind flow, as the wind blows out of the vortex tube 701, when the wind force is large, the elastic ring 7041 can be blown up to expose the internal through hole. At this time, as the wind gets stronger, the through hole gets larger, and the amount of ventilation that can flow will increase. Conversely, the amount of ventilation that can flow will decrease. When the wind stops, the elastic ring 7041 will return to its original state to block the exhaust hole 704, thereby avoiding external objects from causing the exhaust hole 704 to be blocked when not in use.

[0040] Working principle: The mold loading rack 2 is provided with a plurality of rollers 201 for the molding mold mechanism 4. The molding mold mechanism 4 is transported by the rollers 201, which can increase the convenience of the staff to manually install and disassemble the mold. The molding mold mechanism 4 is installed on the production line using the mold loading rack 2. The cylinder 2 501 works, and its moving end drives the T-shaped fixed column 1 502 to rise and fall. At the same time, the driving component 601 drives the plurality of bevel gear components 602 to rotate. The bevel gear components 602 respectively drive the plurality of screw components 603 to rotate, and at the same time drive the plurality of T-shaped fixed columns 2 604 to rise and fall. Then the worker slides the fixed mold 401 and the movable mold 402, so that the guide groove 8 inside the fixed mold 401 moves along the outer side of the T-shaped fixed column 1 502, and the guide groove 8 inside the movable mold 402 moves along the outer side of the T-shaped fixed column 2 604. The movable mold 402 is moved, and then the fixed mold 401 and the movable mold 402 can be fixed by lifting and lowering the T-shaped fixed column 1 502 and the T-shaped fixed column 2 604. After the molding mold mechanism 4 is installed, the mold loading rack 2 is moved away, and the automatic loading equipment is placed at the position of the mold loading rack 2, so that the square blister box can be automatically loaded. The square blister box is then transported and placed inside the fixed mold 401, and then the cylinder 1 301 works, and its moving end drives the lifting seat 302 to move, and the lifting seat 302 can drive the movable mold 402 to move toward the surface of the fixed mold 401, so that the fixed mold 401 and the movable mold 402 are molded, and the pressing head 404 at the bottom of the movable mold 402 presses the square blister box inside the fixed mold 401. At this time, the edge position of the square blister box will be pressed and curled along the shape inside the curling groove 403 for forming.

[0041] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
