Description

Technical Field

[0001] The utility model relates to the technical field of clothing processing, in particular to a bag sewing and shaping mechanism of a clothing bag opening machine. Background Art

[0002] Pocket opening machines are essential auxiliary processing equipment in the garment manufacturing process. They are primarily used to create pockets in specific locations on garments, making it convenient for carrying small items such as mobile phones and wallets. Conventional methods involve separately processing the pocket opening and lip, then sewing the lip to the opening to complete the bag. The pocket opening process involves cutting, folding, positioning and shaping the lip, and finally sewing.

[0003] The conventional bag opening shaping mechanism for opening clothing bags, as described in announcement number CN213061298U, has the following problems and defects: 1. The fabric is shaped only by a single shaping press plate, and the shaping effect is poor, which easily affects the subsequent sewing process; 2. The shaping press plate presses the bag opening and needs to be sewn around. The shaping press plate needs to be lifted up and down once before the interfering part can be sewn. The sewing after lifting is prone to wrinkles, resulting in a defective rate, and the stability performance is poor. Therefore, further improvement is needed. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a bag opening sewing and shaping mechanism for clothing bag opening processing which has a reasonable structure, good shaping effect and good stability.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A pocket sewing and shaping mechanism of a clothing bag opening machine includes a mounting frame and a lifting and lowering material fixing connecting plate that cooperates with the mounting frame; the lifting and lowering material fixing connecting plate is cooperated with an external pressure frame device; the external pressure frame device is installed with an internal pressure plate device; the internal pressure plate device includes a pressure plate frame that slides and cooperates with the external pressure frame device, an internal pressure plate arranged at the front end of the pressure plate frame, a pressure plate lifting assembly that drives the pressure plate frame to rise and fall, and a pressure plate translation assembly that drives the internal pressure plate to slide back and forth on the pressure plate frame; the internal pressure plate intersects with the front end of the external pressure frame device to form a pocket sewing cavity.

[0007] Preferably, the external pressure frame device includes a pressure frame that is lifted and matched on the fixed material connecting plate, a pressure frame cylinder that drives the pressure frame to lift and lower on the fixed material connecting plate, and an external pressure frame arranged at the bottom of the pressure frame. The external pressure frame is correspondingly arranged below the inner pressure plate, and a pressure frame connecting plate is arranged between the pressure frame cylinder and the pressure frame.

[0008] Preferably, the bag opening sewing cavity is formed by the inner pressure plate moving downward under the action of the pressure plate lifting assembly and resting on the outer pressure frame.

[0009] Preferably, the pressure plate lifting assembly includes a slider slidingly fitted on the pressure frame, a pressure plate connecting plate fixed on the pressure plate frame, and a pressure plate lifting cylinder driving the pressure plate frame to lift and lower on the pressure frame. The slider is fixed on the pressure plate frame, and the pressure plate lifting cylinder is linked to the pressure plate connecting plate.

[0010] Preferably, the pressure plate translation assembly includes a translation frame that is slidably fitted on the pressure plate frame, a translation connecting plate arranged on the translation frame, and a pressure plate translation cylinder arranged on the pressure plate frame for driving the translation frame to slide horizontally. The pressure plate translation cylinder and the translation connecting plate are linked and connected, and the inner pressure plate is fixed to the bottom of the translation frame.

[0011] Preferably, axial sliders are symmetrically provided on both sides of the mounting frame.

[0012] Preferably, a radial synchronous belt plate is provided at the center of the mounting frame.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. This practical bag mouth shaping mechanism, the design of the outer pressure frame device and the inner pressure plate device cooperate to form a bag mouth sewing cavity with a certain space for sewing processing. The outer pressure frame and the inner pressure plate cooperate to fix the material and process the bag mouth instead of the traditional single shaping plate bag mouth shaping mode. The layout is reasonable and the bag mouth shaping effect is excellent.

[0015] 2. In this practical bag opening shaping mechanism, the inner pressure plate needs to be lifted up and down once during the process of sewing one circle in order to sew the interference part. At the same time, since the outer pressure frame of the outer pressure frame device is always pressed on the bag opening for shaping, even if the inner pressure plate is partially lifted up for sewing, it will not affect the sewing process, thus avoiding wrinkles, ensuring cost rate and good stability.

The practical bag sewing shaping mechanism performs sewing shaping on the bag mouth shaping mechanism through the external pressure frame on the external pressure frame device 3 and the internal pressure plate 42 on the internal pressure plate device 4. The external pressure frame on the external pressure frame device 3 can be lifted and lowered on the fixed material connecting plate 2 for shaping, and the internal pressure plate 42 on the internal pressure plate device 4 can be moved back and forth by the pressure plate translation component 44 to avoid interference, and is lifted and lowered by the pressure plate lifting component 43 for shaping. The external pressure frame and the internal pressure plate 42 cooperate with the fixed material processing to replace the traditional single shaping pressure plate bag mouth shaping mode, the layout is reasonable, and the bag mouth shaping effect is excellent.

[0019] The external pressure frame device 3 includes a pressure frame 31 that is lifted and matched on the fixed material connecting plate 2, a pressure frame cylinder 32 that drives the pressure frame 31 to rise and fall on the fixed material connecting plate 2, and an external pressure frame 33 arranged at the bottom of the pressure frame 31. The external pressure frame 33 is correspondingly arranged below the inner pressure plate 42. A pressure frame connecting plate 34 is arranged between the pressure frame cylinder 32 and the pressure frame 31. The lifting of the external pressure frame 33 is achieved by the pressure frame cylinder 32 controlling the pressure frame connecting plate 34 and then driving the pressure frame 31 to slide up and down on the entire fixed material connecting plate 2.

The pressure plate translation cylinder 443 and the translation connecting plate 442 are linked together, and the inner pressure plate 42 is fixed at the bottom of the translation frame 441. The pressure plate translation cylinder 443 in the pressure plate translation assembly 44 drives the translation connecting plate 442 to control the translation frame 441 to move back and forth on the pressure plate frame 41, thereby directly controlling the back and forth translation of the inner pressure plate 42. The layout is reasonable and the stability is good.

[0023] Axial sliders 6 are symmetrically arranged on both sides of the mounting frame 1, and the axial sliders 6 ensure the forward and backward movement of the entire mounting frame on the bag opening machine.
