Description

Technical Field

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

[0002] In existing technology, bag opening machines are widely used. Most existing bag opening machines are equipped with a feeder, laser cutting device, bag folding device, and sewing device on the work surface of the bag opening machine. The bag folding device is fixed above the loading area for accessories such as bag eyebrows, bag opening fabric, or zippers, and the feeder slides back and forth between the bag folding device, laser cutting device, and sewing device. The bag opening processing process includes: the feeder determines the position of the bag opening of the garment by the feeder, then the laser cutting device completes the cutting. After cutting, the bag is moved above the accessories and folded by the bag folding device. The garment is then stacked on the accessories and finally moved to the sewing station for sewing. However, this technical solution cannot achieve continuous processing and requires a high degree of manual intervention.

[0003] Chinese utility model patent publication number CN214244833U discloses a continuous production garment bag opening machine. Based on existing bag opening machines, a lower support plate is installed below the bag folding device for placing accessories such as bag eyebrows, bag fabric, or zippers. The material setting device is equipped with an upper plate mechanism that can clamp the lower support plate and move it along with the setting device toward the sewing device. A lower support plate reset device is installed on the work surface to transfer the lower support plate from the upper plate mechanism to the bottom of the bag folding device, achieving continuous processing.

[0004] However, in the above technical solution, after the bag opening is folded, a shaping pressure block needs to be set to maintain the fit between the bag opening and the accessories. At the same time, since the bag folding device is fixedly set above the accessory loading point, the bag opening needs to be transported to the bag folding mechanism for folding after cutting. These factors will cause accessories such as bag eyebrows, bag cloth or zippers to offset and shift during the processing process, thereby affecting the stability of product quality. Utility Model Content

DETAILED DESCRIPTION

[0026] The present invention will be further described below with reference to the accompanying drawings, which are for illustrative purposes only and are not to be construed as limiting the present invention.

[0027] To more concisely illustrate this embodiment, some components well known to those skilled in the art but not relevant to the main content of this invention may be omitted from the drawings or descriptions. In addition, for ease of description, some components may be omitted, enlarged, or reduced in size in the drawings, but they do not represent the dimensions or entire structure of the actual product.

[0028] A bag opening folding device for a bag opening machine, such as Figure 1-5 As shown, it includes a folding mechanism 2 and a dosing mechanism 3 arranged on the work surface of the bag opening machine, and the folding mechanism 2 is arranged on the upper part of the dosing mechanism 3; in the existing bag opening machine, the folding mechanism 2 is fixedly arranged on the work surface, and the dosing mechanism 3 slides at each station on the work surface. When folding the bag, the dosing mechanism 3 runs under the folding mechanism 2; or, the folding mechanism 2 and the dosing mechanism 3 are arranged together, and the folding mechanism 2 and the dosing mechanism 3 move together, and the folding mechanism 2 is also arranged on the upper part of the dosing mechanism 3.

[0029] like Figure 1 As shown, a base 1 is provided, and a folding mechanism 2 is provided on the base 1 through a lifting mechanism; this technology is prior art and will not be described in detail.

[0030] like Figure 2 As shown, the folding mechanism 2 includes a folding knife seat 21, a folding knife group and a folding knife driving mechanism. The folding knife group consists of two X-axis folding knives 23 and two Y-axis folding knives 25. The folding knife driving mechanism includes an X-axis driving mechanism 22 for driving the two X-axis folding knives 23 to rise and fall, and a Y-axis driving mechanism for driving the two Y-axis folding knives 25 to open or reset along the Y-axis direction; the X-axis driving mechanism 22 is generally a cylinder.

[0031] The two X-axis folding knives 23 are relatively arranged at both ends of the X-axis axis of the folding knife seat 21, and the two Y-axis folding knives 25 are relatively arranged on the Y-axis axis of the folding knife seat 21; when the two Y-axis folding knives 25 are relatively opened, the folding knife group is arranged in a rectangular shape.

[0032] like Figure 1 As shown, the material fixing mechanism 3 is provided with a small pressure frame 31 and an external pressure frame 32. The small pressure frame 31 is provided above the external pressure frame 32 and rises and falls above the external pressure frame 32. The external pressure frame 32 and the small pressure frame 31 are provided with bag opening processing windows 34 correspondingly. This setting also belongs to the existing design and will not be repeated.

[0033] like Figure 4 、 Figure 5 As shown, a folding plate 35 cooperating with the two Y-axis folding knives 25 of the folding mechanism 2 is provided on the lower surface of the external pressure frame 32, and a control mechanism for controlling the folding plate 35 to move toward or away from each other is provided on the external pressure frame 32.

[0034] The function of the Y-axis folding knife 25 is to complete the folding of the fabric. When the Y-axis folding knife 25 completes the folding, the folding pressure plate 35 will take over from the Y-axis inserting knife 25 to press the folding so that the Y-axis inserting knife 25 can be withdrawn. However, at this time, the folding edge is easy to loosen and shift, resulting in deformation of the bag opening.

[0035] In order to enhance the strength of the folding knife to fold the bag cloth, it is also necessary to ensure that the folding edge does not become loose, shift or deform when the Y-axis folding knife 25 exits. Figure 4As shown, two folding plates 35 are provided to cooperate with the Y-axis folding knife 25 , and the folding plates 35 are correspondingly provided on the lower surfaces of the two frames on the Y-axis axis of the processing window 34 of the outer pressure frame 32 .

[0036] In order to achieve the perfect replacement of the folding plate 35 and the Y-axis folding knife 25, as shown in FIG. Figure 3 As shown, the Y-axis folding knife 25 includes a vertical portion 252 and a bending portion 253 that are perpendicularly connected to each other. The longitudinal section of the Y-axis folding knife 25 is L-shaped, and the bending portion 253 of the Y-axis folding knife 25 is configured to be composed of a plurality of evenly spaced tooth-like protrusions.

[0037] Accordingly, if Figure 4 As shown, the folding plate 35 is also arranged to have evenly spaced tooth-like protrusions on one side of the bending portion 253 of the Y-axis folding knife 25, and the tooth-like protrusions of the folding plate 35 are staggered with the tooth-like protrusions of the bending portion 253 of the Y-axis folding knife 25.

[0038] Combine Figure 4 、 Figure 5 When the Y-axis folding knife 25 is opened and the folding edge is completed, the control mechanism on the material fixing mechanism 3 causes the two folding pressure plates 35 to move toward their respective matching Y-axis folding knives 25 and move closer together. The toothed protrusions of the folding pressure plates 35 can be embedded in the gaps between the toothed protrusions of the bending part 253 of the Y-axis folding knife 25, thereby pressing the folding edge and perfectly replacing the Y-axis folding knife 25. With this design, the folding edge of the bag cloth will not loosen or shift, and the folding edge can also be narrower than the existing technology, so that the bag opening processed in this way is more beautiful.

[0039] In order to meet customers' different size requirements for products, such as Figure 2 As shown, the X-axis folding knife 23 adjustment slots 212 are symmetrically arranged at both ends of the X-axis axis of the folding knife seat 21, and the X-axis folding knife 23 is arranged in the adjustment slots 212. The setting of the adjustment slot 212 is used to adjust the width between the two X-axis folding knives 23 according to the width of the product bag opening.

[0040] In addition, in order to solve the synchronization problem and edge pressing force of the Y-axis folding knife 25, the gear shaft 241 is used to drive the synchronous movement of the Y-axis folding knife 25. Figure 3 As shown, the Y-axis drive mechanism includes a drive component 24 and a gear shaft 241. The drive component 24 is preferably a motor, which drives the gear shaft 241 to rotate. A rack 251 is provided on the top of each Y-axis folding knife 25. The tooth surfaces of the racks 251 of the two Y-axis folding knives 25 face each other and mesh with the gear shaft 241. The motor drives the gear shaft 241 to rotate, driving the two racks 251 in opposite directions, thereby driving the two Y-axis folding knives 25 to move synchronously toward or away from each other, thereby achieving synchronous closing or opening of the two Y-axis folding knives 25.

[0041] Two Y-axis folding knife slide rails 211 are set at both ends of the X-axis axis of the folding knife seat 21, and the Y-axis folding knife 25 is slidably connected to the folding knife slide rails 211; the sliding connection can be that the Y-axis folding knife 25 is provided with a slide rail seat, and then connected to the slide rail 211 through the slide rail seat to realize the sliding of the Y-axis folding knife 25 on the slide rail 211; it can also be that the rack 251 is connected to the slide rail 211, and the gear shaft 241 rotates to drive the rack 251 to move, thereby driving the movement of the Y-axis folding knife 25 connected thereto; of course, the rack 251 can also be provided with a slide rail seat, and the slide rail seat is connected to the slide rail 211.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. In other words, any equivalent changes and modifications made within the scope of the patent application of the present invention should fall within the technical scope of the present invention.
