Description

Technical Field

[0002] In garment manufacturing, many garments require pocket opening processes. Traditional pocket opening methods include manual pocket opening, mechanical pocket opening, and laser pocket opening. Manual pocket opening is quite complex, requiring seven or eight steps to complete, and its quality is inconsistent and its efficiency is low. There are also automatic mechanical pocket opening machines, which offer high efficiency and stable quality, but have a narrow range of applications and require subsequent steps such as turning the pocket lip and attaching the inner fabric, making mold changes troublesome and very difficult. Laser pocket opening machines typically integrate multiple stations such as laser cutting, folding, and sewing into one machine, achieving automated pocket opening for clothes, trousers, etc. Laser pocket opening machines are equipped with an upper folding and pulling pocket lip mechanism and a lower positioning pocket lip clamping fabric mechanism.

[0051] The front pull rod 33 has a front positioning piece 35 at its front end, and the rear pull rod 39 has a rear positioning piece 36 at its front end. The front positioning piece 35 and the rear positioning piece 36 are driven to perform two actions of moving towards and away from each other. In this technical solution, the positioning component drives one set of bidirectional screw assemblies to rotate through a first driving member. The bidirectional screw assemblies then synchronously drive the other set of bidirectional screw assemblies to rotate. The two sets of bidirectional screw assemblies are driven by the same driving member, so that the front positioning piece on the front pull rod and the rear positioning piece on the rear pull rod can achieve synchronous movement towards and away from each other. The distance between the front positioning piece and the rear positioning piece can be adjusted according to the actual situation to adapt to different sizes of bag lips. It has the advantages of good stability in symmetrical parallel operation and good practicality.

[0052] The bidirectional screw assembly includes:

[0053] The first screw 31 is rotatably mounted on the material support base plate 21 and is provided with positive and negative threads;

[0054] Two first nut sleeves 32, which respectively engage with the positive and negative threads of the first screw 31;

The fourth driving member is a cylinder, hydraulic cylinder or linear motor to drive the bottom clamping plate to rise and fall.

[0080] The bottom clamping plate 25 has a rectangular toothed fabric clamping opening 27 in the middle. The front end of the bottom clamping plate 25 is equipped with a pressure plate support 28 that rotates with the material support base plate 21. A fabric clamping frame 212 with rectangular teeth is installed below the material support base plate 21. The fabric clamping frame 212 cooperates with the fabric clamping opening 27 of the bottom clamping plate 25 to clamp the fabric.

[0081] The upper folding bag lip pulling mechanism includes four levers: front, back, left, and right. The pre-cut left and right bag lip fabric edges are inserted under the material support base plate, with the insertion depth just exceeding the bottom of the left and right positioning plates. Through the teeth on the bottom clamping plate of the lower positioning bag lip clamping mechanism, the bag lip fabric edges being pulled out are alternately pressed and clamped under the front positioning plate, the rear positioning plate, and the left and right positioning plates. Then, the levers corresponding to the left and right positions are withdrawn. After the levers leave the left and right bag lip edges, the left and right levers retract upwards to wait, while the front and back levers retract to the front and back bag lip edges.

[0082] This alternating clamping mechanism for the lower lip of the bag utilizes the toothed grooves of the front, back, left, and right pull plates in conjunction with the toothed grooves of the bottom clamping plate of the lower positioning bag lip clamping mechanism to alternately clamp the lower lip. This provides the advantage of stable operation and solves the instability issues of traditional bag lip rebound and failure to clamp the bag lip. It can also adapt to the openings of garment bags of different sizes.
