Thermoplastic mould cup trimming device

Abstract

The invention discloses a thermoplastic mould cup trimming device which comprises a base the shape of which is the same as that of the mould cup. The trimming device also comprises an edge tracing guide device and a cutter device matched with the edge tracing guide device, wherein the edge tracing guide device is connected with a rotating shaft of a drive motor. In the thermoplastic mould cup trimming device, the cutter device matched with the edge tracing guide device is driven to work by the drive motor, and because the structure of the edge tracing guide device is the same as the shape of the mould cup, the moving track of the cutter deice moving along the edge tracing guide device under the driving of the drive motor is the same as the shape of the mould cup; and the cutter device and the base are matched with the edge tracing guide device, which ensures that a mould cup corner placed between the edge tracing guide device and the base is better cut off so as to achieve the purpose of trimming. Compared with the prior art, the thermoplastic mould cup trimming device can better and orderly cut a three-dimensional mould cup corner, improve the cutting efficiency and be widely applied to bra mould cups, shoulder pads, and the likes.

Description

technical field [0001] The invention relates to the field of trimming devices for thermoplastic mold cups, in particular to a three-dimensional thermoplastic mold cup trimming device. Background technique [0002] Bras are usually three-dimensional cup-shaped structure, in order to fit the breasts well and reshape the figure. [0003] The existing three-dimensional brassiere is usually made of a mold cup molded in a thermoplastic manner. When the mold cup is thermoplastically molded, corners are usually produced at the edge of the mold cup. Therefore, in the production process of brassiere, it is necessary to trim the corners of the mold cup. Since the mold cup is a three-dimensional structure, each edge position of the mold cup may be on a different surface, so the existing two-dimensional trimming device or manual cutting is usually used. When two-dimensional trimming device is used for trimming, the edge of the mold cup after trimming is not neat, and the mold cup after...

AI Technical Summary

Problems solved by technology

When two-dimensional trimming device is used for trimming, the edge of the mold cup after trimming is not neat, and the mold cup after trimming cannot meet the requirements. Generally, the error is required to be within the range of 2 mm; if manual trimming is used, the trimming The edge efficiency is low, and the edge cutting is affected by the experience of the cutting personnel, and the cutting accuracy is not high, resulting in inconsistent cutting standards, resulting in unqualified quality
