[0031] like Figure 1-2 As shown, a feeding device for plastic sheet vacuum forming includes a mounting base 1 and a fixed base 2. The fixed base 2 is fixedly connected to the top of the mounting base 1. The fixed base 2 consists of four vertical rods and a circular plate. It also includes a position adjustment component and a suction component. The position adjustment component is located at the upper end of the fixed base 2 and includes a rotating disc 3, a vertically moving slider 4, and a horizontally moving adjustment block 5 for flexible feeding of plastic sheets. The suction component is located at the lower end of the adjustment block 5 for sucking up and putting down the plastic sheets.

[0032] like Figure 1-5As shown, to improve the flexibility of material loading, the position adjustment assembly includes a servo motor 6, a vertical plate 7, a linear guide rail 8, a horizontal plate 9, a linear guide rail 10, a guide frame 11, a limiting block 12, a guide rod 13, a limiting frame 14, and a guide bar 15. The servo motor 6 is fixedly installed on the top of the mounting base 1, and its output end vertically penetrates the fixed base 2 and is rotatably connected to it. The disc 3 is fixedly connected to the output end of the servo motor 6. The limiting block 12 is fixedly connected to the bottom of the disc 3 and is C-shaped. The inner wall of the limiting block 12 fits against the outer wall of the fixed base 2. The rotation of the limiting block 12 on the fixed base increases the stability of the disc 3 during rotation. The vertical plate 7 is fixedly connected to the top of the disc 3. Symmetrically distributed reinforcing plates 21 are fixedly connected at the connection between the disc 3 and the vertical plate 7 and are triangularly arranged to increase the stability between the vertical plate 7 and the disc 3. The linear guide rail 8 is fixedly installed on the outer wall of the vertical plate 7. The slider 4 is slidably mounted on the linear guide rail 8. The guide rod 13... The guide rod 13 is fixedly connected to the outer wall of the vertical plate 7. The guide rod 13 is C-shaped. The limiting frame 14 is fixedly connected to the outer wall of the slider 4 and vertically passes through the guide rod 13 and is slidably connected to it. The limiting frame 14 is C-shaped. The limiting frame 14 slides on the guide rod 13 to increase the stability of the slider 4 when sliding vertically. The horizontal plate 9 is fixedly connected to the outer wall of the slider 4. The linear guide rail 10 is fixedly installed at the bottom of the horizontal plate 9. The adjusting block 5 is slidably set on the linear guide rail 10. The guide frame 11 is fixedly connected to the adjusting block 5. The guide frame 11 is composed of a square plate and an inclined U-shaped frame. The square plate is fixedly connected to the bottom of the adjusting block 5. The guide strip 15 is fixedly connected to the top of the horizontal plate 9. The frame and the guide strip 15 are slidably connected. The sliding of the frame on the guide strip 15 increases the stability of the adjusting block 5 when moving. The position of feeding can be flexibly adjusted by rotating the disc 3, sliding the slider 4 vertically, and moving the guide frame 11 laterally driven by the adjusting block 5.

[0033] like Figure 4-6 As shown, in order to quickly and stably complete the suction and placement of plastic sheets, the suction assembly includes a cylinder 16, an electric push rod 17, a piston 18, a connecting tube 19, and a suction cup 20. The cylinder 16 is fixedly connected to one bottom end of the square plate, the electric push rod 17 is fixedly connected to the inner top of the cylinder 16, the piston 18 is fixedly connected to the free end of the electric push rod 17, the connecting tube 19 is fixedly connected to the bottom of the cylinder 16, and four sets of them are arranged in a ring and communicate with the inside of the cylinder 16. The connecting tube 19 is bent, and the suction cup 20 is fixedly connected to the lower end of the connecting tube 19. By controlling the downward and upward movement of the piston 18 through the extension and retraction of the electric push rod 17, the suction and placement of the plastic sheet can be completed.

[0034] In practical use, the servo motor 6 is turned on, and the rotation of the disc 3 adjusts the direction of the suction cup 20. When the disc 3 rotates, it drives the limit block 12 to rotate on the fixed base 2. The linear guide rail 8 is controlled to make the slider 4 slide vertically, thereby adjusting the vertical position of the suction cup 20. As the slider 4 moves vertically, it drives the limit frame 14 to slide on the guide rod 13, increasing the stability of the slider 4 during sliding. The linear guide rail 10 is controlled to make the adjusting block 5 drive the guide frame 11 to move laterally, thereby adjusting the position of the suction cup 20. The position is adjusted laterally. When the guide frame 11 moves laterally, it slides on the guide strip 15, which increases the stability of the guide frame 11. When picking up the plastic sheet, after the suction cup 20 is attached to the plastic sheet, the electric push rod 17 is controlled to retract. The piston 18 moves upward so that each suction cup 20 sucks the plastic sheet tightly. Then, the plastic sheet is placed at the loading position by the above-mentioned adjustment mechanism for the position of the suction cup 20. The extension of the electric push rod 17 can separate the plastic sheet from the suction cup 20, thus completing the loading operation of the plastic sheet.
