Description

Technical Field

[0001] The utility model belongs to the field of clothing processing machinery, and more specifically relates to a material setting device for a bag opening machine. Background Art

[0002] In the process of garment processing, the bag opening machine is an indispensable auxiliary processing machine. When processing fabrics, the bag opening machine needs to cut, fold and sew at the bag opening; cutting is to make a "Y"-shaped slit at both ends of the bag opening; folding is to fold the bag opening that has been cut inward to form a flange; the sewing operation includes sewing the bag opening that has been folded, and sewing the fabric and zipper at the bag opening; among them, the sewing step is generally carried out by the fixed material device in the bag opening machine to transport the fabric to the sewing machine, and the sewing machine completes the sewing operation on the fabric transported by the fixed material device.

[0003] For example, a Chinese patent with an application date of December 26, 2020 and patent number CN202023039502.5, discloses a material taking and fixing device for a clothing pocket opening machine, including a sliding table for sliding installation on the pocket opening machine, and an outer pressure frame and a small pressure frame connected to the lower pressure assembly are arranged to be lifted and lowered on the sliding table for supporting the outer pressure frame under the fabric; when performing the sewing step, the outer pressure frame transports the fabric to the sewing machine, and the small pressure frame is used to close the outer pressure frame to fix the bag opening or the zipper head to the fabric, and the needle of the sewing machine moves along the sewing path in the small pressure frame to sew the bag opening after the folded bag is completed, and sew the fabric and the zipper head at the bag opening.

[0004] However, since zippers often have zipper heads, which are made of rigid materials and are long strips, the long zipper head will often interfere with the needle of the sewing machine during the process of sewing the cloth and the zipper head at the bag opening. One end of the zipper head is arranged on the upper side of the cloth and is located on the sewing path. As the sewing machine continues to work, the needle of the sewing machine will collide with the zipper head, which will damage the needle of the sewing machine and cause losses to the equipment. On the other hand, the needle cannot pass through the zipper head to sew the zipper to the garment or cloth, resulting in the loose and unsightly sewing of the bag opening and the zipper, affecting the quality of the product. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a material metering device for a bag opening machine, which can control the zipper head to be away from the sewing path of the sewing machine, avoid the collision between the needle of the sewing machine and the zipper head, and ensure the yield rate of the product.

[0006] The utility model discloses a material setting device for a bag opening machine, comprising a large pressing frame for supporting the upper layer of fabric and a small pressing frame for pressing and fixing the upper layer of fabric.

[0009] Each group of air blowing mechanisms corresponds to at least one sewing path; each group of air blowing mechanisms operates independently; when there is a sewing machine head on the sewing path, the corresponding air blowing mechanism is in an operating state.

[0010] As a further improvement of the utility model, the blowing mechanism is divided into two groups, and the air outlets corresponding to the two groups of blowing mechanisms are respectively opened on both sides of the shaping window in the length direction.

[0011] As a further improvement of the utility model, the zipper head is arranged at one end of the shaping window, and the air outlet direction of the air outlet is arranged toward the zipper head, so that the air outlet direction of the air outlet is inclined.

[0012] As a further improvement of the utility model, two blowing channels are provided in the small pressure frame, and the two blowing channels are respectively arranged on both sides of the length direction of the shaping window; the blowing channels are connected with the corresponding air outlets on the same side; an air pump connecting port is provided at one end of each blowing channel, and each air pump connecting port is connected with the corresponding blowing channel and an external air pump; the external air pump controls the two blowing channels to ventilate independently.

[0013] As a further improvement of the utility model, on each inner wall of the shaping window, a plurality of air outlets are evenly distributed along the length direction of the shaping window.

[0014] As a further improvement of the utility model, the air pump connection port is opened on the left and right side surfaces / upper and lower end surfaces of the small pressure frame.

[0019] (1) The toggle mechanism can toggle the zipper head to the back side when the sewing machine is processing the front side of the zipper, and can toggle the zipper head to the front side when the sewing machine is processing the back side of the zipper, so as to avoid the zipper head interfering with the needle of the sewing machine during the processing, so that the stitches of the product obtained after processing are uniform and tight, the style is beautiful, and the quality is high;

The air pump connection port 254 is provided on the left and right side surfaces / upper and lower end surfaces of the small pressure frame 25. The air pump connection port 254 is connected to the air blowing channel 253 and an external air pump, so that the external air pump blows air into the air blowing channel 253 through the air pump connection port 254.

[0050] It should be noted that when the number of external air pumps is one, an electromagnetic tee is connected between the external air pump and the air blowing channel 253, and the electromagnetic tee is connected to the two air blowing channels 253, so that the electromagnetic tee controls the external air pump to ventilate the two air blowing channels 253 independently;

[0053] Preferably, the blowing hole 252 is arranged parallel to the work surface 11, and the blowing hole 252 is inclined relative to the length direction of the shaping window 251. The blowing hole 252 is inclined toward the zipper head from the end away from the zipper head to the end close to the zipper head, so that the blowing direction of the blowing hole 252 is toward the zipper head.

[0054] Working principle: When the shaping window 251 is set corresponding to the material setting window 241, and a zipper head is set in the shaping window 251, a sewing machine is required to sew the zipper head and the clothing fabric;

[0055] During sewing, the length direction of the zipper and the zipper head is the same as the length direction of the shaping window 251. At this time, the sewing machine needs to work on the front and back sides and the left and right sides of the zipper head to sew the zipper with the clothing fabric. Since the zipper head is movable relative to the zipper, the zipper head may interfere with the sewing of the sewing machine on its front and back sides.

[0056] When the sewing machine is ready to work on the front side of the zipper head for sewing, the external air pump connected to the blowing channel 253 located on the front side works to blow air into the blowing channel 253, so that the blowing hole 252 blows air toward the zipper head, so that the zipper head is forced to move in a direction away from the blowing hole 252 on the front side, thereby avoiding interference with the zipper head when the sewing machine works on the front side of the zipper head for sewing;

[0057] When the sewing machine is ready to work at the rear side of the zipper head for sewing, the external air pump connected to the blowing channel 253 located at the rear side works to blow air into the blowing channel 253, so that the blowing hole 252 blows air toward the zipper head, so that the zipper head is forced to move in the direction away from the blowing hole 252 on the rear side, thereby avoiding interference with the zipper head when the sewing machine works at the rear side of the zipper head for sewing.
