A film-pressing and groove-pressing device applied to large-area and complex plastic-absorbing molds

Abstract

The invention discloses a film and groove pressing device applied to a large-area complex plastic suction mold. The film and groove pressing device comprises a shaping device arranged on a working table. The shaping device comprises a fixed frame. A positioning rod is arranged in the fixed frame in the vertical direction. A set of balls are arranged on the rod wall of the positioning rod. An inner core rod is arranged in the length direction of the positioning rod. A central rod is arranged in the length direction of the inner core rod. Compared with the prior art, by means of the film and groove pressing device applied to the large-area complex plastic suction mold, a plastic suction plate can be tightly attached to the inner portion of the irregular plastic suction mold through pressure so that the phenomenon that due to the fact that the shape of the plastic suction mold is irregular, folds, gaps and excessive stretching are generated on the plastic suction plate where plastic suction is conducted can be prevented.

Description

technical field [0001] The invention relates to a film-pressing device used on a plastic-absorbing mold, in particular to a film-pressing and groove-pressing device applied to a large-area and complicated plastic-absorbing mold. Background technique [0002] Since the development of the blister process, the improvement of its process has been able to meet the needs of most users, and the quality of the blister products depends on the occurrence of the blister process and the material of the plastic sheet. Generally, there are many choices of PET materials. The material has good plasticity and is suitable for various blister machines. This material is especially suitable for use on some molds with complex structural shapes. There is no need to worry about the phenomenon that the folding depth caused by complex shapes is difficult to absorb completely or excessive stretching. However, this material costs Higher, more waste in use, but ordinary plastic sheet is prone to defecti...

AI Technical Summary

Problems solved by technology

There are multiple suction holes drilled on the cylindrical surface of the outer film roller on the vacuum suction roller. When the blown film meets the suction holes, the film is sucked into the suction holes by the vacuum suction of the suction holes and cooled. After the film is separated from the blister hole, small bumps are formed on the film surface, realizing the purpose of embossing on the film; this scheme uses the blister hole on the blister roller to carry out the blister work, which is different from the common blister The difference between reverse implementation, the blister shape produced by this method cannot be guaranteed, and it cannot meet the utilization of molds with irregular shapes
