Description
Technical Field
[0001] This utility model relates to the field of coating technology for V-process casting models, specifically a tension adjustment mechanism for coating V-process casting models. Background Technology
[0002] V-process casting (vacuum-sealed molding) uses a plastic film to seal the sand box and utilizes vacuum negative pressure to compact the dry sand into shape. Its core steps include film heating and softening, vacuum adsorption molding, dry sand filling, and pouring.
[0003] During the coating stage, the film needs to be evenly adhered to the surface of the model. Tension control directly affects the quality of the casting. The film needs to be tightly adhered to the model through vacuum adsorption. Insufficient tension will cause wrinkles or poor adhesion, while excessive tension may tear the film.
[0004] Existing adjustment devices rely on rotating screws to change the spacing between guide rollers and manually adjust film tension. However, manual operation depends on the operator's experience and cannot adapt to dynamic tension changes, thus affecting production efficiency. Utility Model Content
