Automatic folding mechanism and method and sleeve placket sewing device

Abstract

The invention provides an automatic folding mechanism and method and a sleeve placket sewing device. The automatic folding mechanism comprises a fixing base plate, a discharging plate, a baffle assembly, a discharging cavity formed by the discharging plate and the baffle assembly, a turnover clamping assembly located in the discharging cavity and a fold material shifting piece. One end of the discharging cavity is provided with a sleeve placket end forming part, a plurality of first suction holes distributed in the peripheral direction of the discharging cavity at intervals are formed in the discharging plate, the clamping assembly comprises a movable clamping plate and a fixed clamping plate which are stacked, and a clamping cavity formed in the movable clamping plate and the fixed clamping plate, the movable clamping plate can move close to or away from the fixed clamping plate, the fold material shifting piece is located at the upper side of the baffle assembly and can move close toor away from the sleeve placket end forming part. The small cutting pieces and large cutting pieces are automatically folded into sleeve plackets, operators just need to place the small cutting pieces and the large cutting pieces, time and labor are saved during operation, and the cutting piece folding efficiency and quality are greatly improved.

Description

technical field [0001] The invention relates to an automatic folding mechanism. [0002] The present invention also relates to an automatic folding method for folding the sleeve fork by using the above automatic folding mechanism. [0003] The present invention further relates to a cuff sewing device comprising the above-mentioned automatic folding mechanism. Background technique [0004] At present, the general steps of sewing the sleeve fork are: 1. Place the small cut piece; 2. Fold the small cut piece so that the rear end of the small cut piece is folded out of the sharp corner of the sleeve fork; 3. Place the large cut piece, and make the big cut piece A part of the sheet is clamped in the small cut piece, and the other part of the big cut piece is located above the small cut piece; 4. The large cut piece and the small cut piece are stitched together to complete the sewing of the sleeve fork. It can be seen from this that the folding of small pieces and large pieces i...

AI Technical Summary

Problems solved by technology

If the pieces are folded manually, the sewing quality and efficiency of the sleeve fork will be directly and greatly reduced, which cannot meet the requirements of modern production
