Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of garment machinery, and particularly relates to a folding mechanism for a garment bagging machine. BACKGROUND

[0002] In the process of garment processing, a bagging machine is an essential auxiliary processing machine, which is mainly used to form a pocket at a specific position of a garment to facilitate carrying small items such as a mobile phone and a wallet. The conventional method is to separately process a bag mouth and a bag lip, and then sew the bag lip to the bag mouth to complete the bagging. The processing of the bag mouth needs to be cut, folded, positioned, shaped and sewn. The folding of the bag mouth is to fold the cut bag mouth inward to form a flange. The utility model patent with the application number 202020675344.3 (the authorized announcement number is CN 212655959U) discloses a bag mouth folding mechanism for garment bagging processing, which comprises a folding seat and a fixed plate suspended above a processing station. The fixed plate is vertically arranged on the folding seat. The fixed plate is provided with four sets of folding knives forming a rectangular contour. Each set of folding knives is connected with a lifting assembly and a horizontal moving assembly. The lifting assembly can drive the folding knives to complete the vertical lifting movement. The horizontal moving assembly can drive the folding knives to move axially or radially on the horizontal plane to fold the bag mouth downward. The bag mouth folding mechanism disclosed in the technical solution is located above the processing station. The structure of the lifting fixed plate makes the folding knives close to the bag mouth. The lifting assembly and the horizontal moving assembly in the folding knives fold the bag mouth downward to realize the folding process. It is convenient to cooperate with other mechanisms of the bagging machine to realize automatic bagging processing, reduce labor cost and improve processing efficiency. However, the folding knives of the structure cannot be quickly replaced. The folding knives are installed on the folding guide rail plate through the sliding cooperation of the sliding block and the guide rail. The folding knives do not have a dismounting and locking structure, which makes them unable to adapt to the folding processing of different types and sizes of bag mouths, and the use is extremely inconvenient.

[0003] In view of this, the Chinese utility model patent with the application number 202220630108.9 (the authorized announcement number CN218026643U) discloses a bag folding mechanism of a bag opening machine, which comprises a bag folding seat, a fixed plate and four groups of cloth folding knives combined to form a rectangular contour. The fixed plate is driven by a lifting cylinder to be lifted and arranged on the bag folding seat. Four rectangular folding knife adjusting plates are arranged on the fixed plate. Each folding knife adjusting plate is arranged on the bottom of the fixed plate in a lifting and axial or radial horizontal manner. A clamping dovetail block is arranged on the folding knife adjusting plate and is clamped by a clamping cylinder. The cloth folding knife is detachably locked between the clamping dovetail block and the folding knife adjusting plate. The cloth folding knife is locked between the clamping dovetail block and the folding knife adjusting plate by the driving of the clamping cylinder, which realizes detachable connection and facilitates the disassembly and assembly of the cloth folding knife to adapt to different types and sizes of bag opening folding processing, and improves the processing efficiency and application range to a certain extent. However, such bag folding mechanism also has some disadvantages: each group of cloth folding knives is driven by a pair of cylinders arranged on the folding knife adjusting plate, and four groups of cloth folding knives are driven by eight groups of cylinders at the same time. Too many cylinder settings will make the structure of the whole bag folding mechanism complex and cumbersome, increase the cost, and also affect the production efficiency, so further improvement is needed. In addition, when encountering soft and thin cloth, the edges of the folded cloth will sag after folding, which will cause wrinkles in the subsequent sewing process, thereby affecting the processing quality.

[0004] Therefore, how to provide a cloth folding structure for a garment bag opening machine which can make the overall structure of the cloth folding mechanism more simplified and optimized, and also applicable to various types or specifications of cloth, is a problem that needs to be solved by those skilled in the art.
