[0034] Among them, the control module can be but is not limited to using PLC; first, the lower mold pulling mechanism 4 is controlled to open by PLC, and the PVC film is placed on the lower mold 13, and then the temperature sensor on the heating plate 6 is controlled by PLC. When the temperature on the temperature sensor reaches a preset value, the PLC controls the driving mechanism 5 to descend, and the PVC film is clamped between the upper mold 7 and the lower mold 13 to form a closed space, and then the vacuum generator 8 is controlled by PLC to work, and the gas is transmitted to the upper mold 7 through the heating plate 6, and then the PVC film is blown through the blowing hole on the upper mold 7. The pressure of the gas is used to make the PVC film quickly formed under the action of the upper mold 7 and the lower mold 13, and finally the desired blister product is formed. The upper mold 7, lower mold 13 and heating plate 6 are separated. When quickly switching molds, there is no need to involve any wiring or plugging and unplugging of air pipes. The replacement is convenient and the switching of the upper mold 7 and lower mold 13 can be completed in ten seconds. This design not only saves time for mold replacement and improves production efficiency, but also reduces the risk of equipment damage and failure caused by frequent plugging and unplugging. The ability to quickly change molds allows the equipment to quickly adapt to the production of different products, thereby improving the flexibility and response speed of the production line.

[0035] In this embodiment, a touch screen 201 is provided on the front of the housing 2. All operating and display functions are integrated into the touch screen 201. The PLC's recipe parameters are integrated, allowing for one-touch molding at the preset temperature, eliminating the need for manual time control and maintaining temperature control, thus enhancing the user experience. All operating and display functions are integrated into the touch screen 201, creating an intuitive and easy-to-understand interface that significantly reduces the learning curve and operational difficulty for operators. The use of the touch screen 201 not only enhances operational flexibility but also facilitates real-time monitoring and data logging of the equipment.

The lower mold 13 is fixedly mounted on the lower mold support plate 402. When the drawer panel 401 is pulled outward (with the inner direction of the shell as the inner direction), the first guide shaft 404 moves linearly along the box-type linear bearing 403, thereby playing a guiding role. The lower mold support plate 402 is pulled by the drag chain 405 to prevent the lower mold support plate 402 from falling off, thereby realizing the placement or replacement of the product.

[0038] The front bottom of the housing 2 is provided with a pull-out opening 202. The pull-out opening 202 is provided to facilitate the drawer panel 401 to pull out, and the pull-out opening 202 is adapted to the drawer panel 401 to ensure internal sealing.

[0039] In this embodiment, an electric lock tongue is installed inside the drawer panel 401. Upon receiving a valid signal, the PLC drives the electric lock tongue to move, thereby unlocking the drawer. After closing the drawer, the electric lock tongue automatically returns to its original position, ensuring the safety of the device. When the built-in sensor of the electric lock tongue detects an abnormality, the PLC controls the electric lock tongue to lock. This design can effectively prevent burns or crushing injuries caused by misoperation during work. This design fully considers the safety needs of operators and embodies the concept of humanized design.

The cylinder 501 is driven by PLC control to move the floating joint 503 up and down, thereby driving the ultra-thin cylinder 504 to move up and down along the second guide shaft 506, and then moving the upper mold 7 located at the bottom of the heating plate 6 up and down.

[0043] In this embodiment, tooling guide bars 507 are provided on both sides of the heating plate 6 along the pulling direction; the tooling guide bars 507 are fixedly connected to the bottom of the ultra-thin cylinder 504; and the opposing inner sides of each tooling guide bar 507 are provided with a clamping groove 5071. The two clamping grooves 5071 support and clamp the upper mold 7, making the upper mold 7 and the heating plate 6 fit together, thereby achieving heat conduction of the upper mold 7.

[0044] In this embodiment, the distribution board 9 is equipped with a solenoid valve 10 and an electrical proportional valve 11, both of which are electrically connected to the driving cylinder 501. The solenoid valve 10 and the electrical proportional valve 11 are provided to control the on / off state of the driving cylinder 501.

[0045] In this embodiment, fans 12 are provided on the side and rear of the housing 2. The fans 12 can effectively dissipate heat inside the blister machine.
