Description

Technical Field

[0001] The utility model relates to the technical field of clothing processing, in particular to a pressing frame component of a bag opening machine. Background Art

[0002] In the process of garment processing, the pocket opening machine is an indispensable auxiliary processing machine, which is mainly used to form pockets at specific positions of garments to facilitate carrying small items such as mobile phones and wallets. The conventional method is to process the pocket opening and the pocket lip separately first, and then sew the pocket lip to the pocket opening to complete the pocket opening.

[0003] The pocket opening processing requires cutting, folding, lip shaping and sewing of the pocket opening of the garment. Cutting means making a "Y"-shaped crack at both ends of the pocket opening, folding means folding the cut pocket opening inward to form a flange, lip shaping means placing the bag lip on the flange, and finally sewing.

[0004] Specifically, in the sewing process, the pressing frame initially presses the fabric onto the dowel knife, and will first withdraw the two dowel knives on both sides and the front, then sew the three sides, then place a piece of bottom fabric under the fabric, push out the rear dowel knife, and finally sew the back side.

[0005] However, the current press frame is a four-sided integrated press on four dowel knives. Since the sewing is divided into two processes, in the first three-side sewing process, only three dowel knives are withdrawn, and the pressing height of the press frame remains at that height. When the last side is sewn, the dowel knives at the rear are withdrawn, and the press frame becomes loose and fails to completely press the rear side of the fabric, resulting in pocket defects during sewing.

DETAILED DESCRIPTION

[0020] The utility model embodiment provides a pressing frame assembly of a bag opening machine, such as Figure 1-2As shown. The pressing frame assembly is arranged on the substrate 1, and the substrate 1 is a component of the bag opening machine. The structure of the bag opening machine refers to an automated real bag manufacturing machine with the publication number CN221167014U, and the frame-type "pressing plate 6" recorded therein is a technical point for its improvement in this case. A notch is arranged on the substrate 1. A material fixing assembly and a material pulling assembly corresponding to the notch are arranged in the substrate 1. The specific structures of the material fixing assembly and the material pulling assembly are consistent with the structures of the "material fixing mechanism 7" and "material pulling mechanism 8" in CN221167014U, and will not be described in detail.

[0021] like Figure 1 As shown, the frame pressing assembly includes a frame pressing platen 2, a pressure strip platen 3, an outer frame pressing 7, an inner pressure strip 8, a driving cylinder 9 and a tension spring 4. A downward pressure cylinder for driving the frame pressing platen 2 to rise and fall is arranged on the base plate 1. In order to improve the lifting stability of the frame pressing platen 2, a slide rail is vertically arranged on the base plate 1, and a slide block slidably adapted in the slide rail is arranged on the frame pressing platen 2.

[0022] The pressure strip table 3 is connected to the frame pressing table 2 through a tension spring device 4. The tension spring device 4 is a sleeve body, in which a spring is arranged. A through hole is opened on the pressure strip table 3. The sleeve body is fixedly covered on the through hole. The spring inside the sleeve passes through the through hole and is connected to the frame pressing table 2. The tension spring device 4 is used to provide tension to the pressure strip table 3 so that it can press the cloth.

[0023] The driving cylinder 9 is arranged on the pressing frame table 2 and is used to drive the inner pressing strip 8 to rise and fall. In order to improve the stability of the pressing strip table 3 when it is raised and lowered, a vertical slide rail 5 is vertically arranged on the pressing frame table 2, and a slider 6 is provided on the pressing strip table 3 and is slidably adapted on the vertical slide rail 5.

[0024] The outer pressing frame 7 is arranged on the pressing frame plate 2, and the outer pressing frame 7 and the inner pressing strip 8 form a four-sided frame. The outer pressing frame 7 is three sides of the frame, specifically the left and right sides and the front side; the inner pressing strip 8 is the back side of the frame. The outer pressing frame 7 and the inner pressing strip 8 correspond to the top of the notch. The outer pressing frame 7 is used to fix the left and right sides and the front side of the cloth bag, and the inner pressing strip 8 is used to fix the back side of the cloth bag.

[0025] When the pressing cylinder drives the pressing frame platen 2 to press down, the outer pressing frame 7 and the inner pressing strip 8 are pressed down synchronously, and the driving cylinder 9 is used to independently drive the inner pressing strip 8 to press down.

[0026] In order to make the outer pressure frame 7 and the inner pressure strip 8 adaptable to the manufacture of pockets of different sizes, a front pressure strip 10 and a rear pressure strip 11 with adjustable longitudinal distances are respectively provided on the front edge of the outer pressure frame 7 and the inner pressure strip 8 .

[0027] Specifically, the front pressure strip 10 and the rear pressure strip 11 are both provided with a long strip-shaped adjustment groove 13 along the longitudinal direction thereof, and the outer side of the adjustment groove 13 can be open for easy disassembly. The outer pressure frame 7 and the inner pressure strip 8 are both provided with fixing holes 12 corresponding to the adjustment groove 13. The adjustment groove 13 of the front pressure strip 10 and the fixing hole 12 of the outer pressure frame 7, and the adjustment groove 13 of the inner pressure strip 8 and the fixing hole 12 of the rear pressure strip 11 are all connected by bolts.

[0028] like Figure 2 As shown, two side pressure strips 14 are also included, a plurality of positioning holes 15 are provided at intervals along the transverse length direction on the front edge of the outer pressure frame 7 or the inner pressure strip 8, and connecting holes 16 corresponding to the positioning holes 15 are provided on the side pressure strip 14. The positioning holes 15 and the connecting holes 16 are connected by bolts.

[0029] Working principle:

[0030] Step 1: Place a piece of fabric for pocket opening on the substrate 1, and then use the laser cutting mechanism to cut a "Y"-shaped opening or an "I"-shaped opening according to the size of the pocket;

[0031] Step 2: The knife inserting mechanism and the material pulling component in the base plate 1 perform a bag folding action on the pocket;

[0032] Step 3: the downward pressure cylinder drives the outer pressure frame 7 and the inner pressure strip 8 to press down synchronously, pressing the folded pocket edge onto the setting knife, and then the base plate 1 drives the cloth to move horizontally to the sewing area.

[0033] Step 4: The left, right and front three material-setting knives corresponding to the outer pressure frame 7 withdraw, and the sewing mechanism sews the corresponding three sides.

[0034] Step 5: Place a second pocket base fabric under the base plate 1 so that the base fabric and the base fabric on the base plate 1 overlap each other.

[0035] Step 6, the dosing knife at the rear side withdraws, and the driving cylinder 9 drives the inner pressing strip 8 to press down, so that it firmly presses one side of the pocket at the rear side, and then the sewing mechanism sews it.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
