Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, specifically to a thermoforming device for plastic processing that prevents misalignment of the seal. Background Technology

[0002] Plastic products are often processed using a thermoforming process. To prevent misalignment during processing, a thermoforming device for plastic processing is needed to prevent misalignment.

[0003] A patent document with authorization announcement number CN216300144U discloses a thermoforming device for plastic processing that prevents misalignment during sealing. This utility model includes: a hydraulic cylinder with an upper support plate mounted at its bottom, a middle support column mounted below the upper support plate, and a support base mounted below the middle support column; a heating groove formed on the surface of the support base, a workpiece groove formed on one side of the heating groove, a horizontal clamp mounted above the workpiece groove, and a connecting groove cover formed inside the support base to prevent misalignment during sealing. Compared with existing technologies, this thermoforming device places the workpiece to be sealed into the workpiece groove and pushes it towards the heating groove. Because the height of the workpiece groove is lower than the surface of the support base, the workpiece is held in place by the heating groove, ensuring the sealing point of the workpiece is horizontally aligned. The horizontal clamp then firmly clamps the workpiece inside the workpiece groove, preventing loosening and ensuring the sealing position of the workpiece is not misaligned.

A positioning screw block 13 is threadedly connected to the outer end of the threaded rod 11. A support guide rod 14 is fixedly installed at the top of the worktable 1. The top end of the support guide rod 14 is fixedly connected to the bottom end of the U-shaped bracket 9. A slider 15 is movably installed at the outer end of the support guide rod 14. A limit rod 16 is fixedly installed between the positioning screw block 13 and the slider 15. A support rod 17 is fixedly installed on one side of the positioning screw block 13 and the slider 15, away from the positioning screw block 13. A connecting plate 18 is fixedly installed on one side of the slider 15. Two limiting guide rods 19 are fixedly installed on the top of the worktable 1 away from the U-shaped bracket 9. Two limiting holes 20 are opened at the top of the connecting plate 18. The limiting guide rods 19 extend through the limiting holes 20 to the top of the connecting plate 18.

[0026] Working principle: When needed, first, the anti-misalignment thermoforming device for plastic processing is stably placed in the required position using the placement foot 27. The plastic molding film is placed on the molding mold groove 2. The second motor 10 is started to rotate the threaded rod 11, causing the positioning screw block 13 to move downwards on the threaded rod 11, driving the limiting rod 16 to move. Simultaneously, the limiting rod 16 drives the slider 15 to move on the support guide rod 14, causing the connecting plate 18 and the heating block 21 to move, fitting the heating block 21 into the molding mold groove 2. The limiting guide rod 19 moves within the limiting hole 20, adjusting the connection plate 18 and the heating block 21. This process prevents misalignment during sealing. Simultaneously, heating wire 22 is activated to heat heating block 21, which in turn heats the plastic molding film. At the same time, vacuum pump 24 is activated to generate negative vacuum pressure through vacuum tube 25. Subsequently, the heated and softened plastic workpiece film is adsorbed onto the inner wall of molding mold trough 2 through suction hole 23 for molding. Then, the second motor 10 is activated again to move positioning screw block 13 upward on threaded rod 11, which in turn moves connecting plate 18 and heating block 21 upward. At the same time, the first motor 6 is activated to rotate fan blades 7, which exhaust air through exhaust mesh 8 to cool the heated and softened plastic workpiece and improve molding efficiency.
