Description

Technical Field

[0001] This invention relates to the field of garment processing machinery technology, specifically to a bag opening forming device for a bag opening machine. Background Technology

[0002] In the prior art, pocket opening machines are widely used. Chinese invention application CN111575926A discloses a pocket opening machine for processing garment pocket openings. Its technical solution discloses that a material fixing device, a laser cutting device, a pocket folding device, and a sewing device are set on the worktable of the pocket opening machine. The pocket folding device is fixedly positioned above the material feeding area for accessories such as the bag flap, pocket opening fabric piece, or zipper. The material fixing device slides back and forth between the pocket folding device, the laser cutting device, and the sewing device. The pocket opening processing includes: the material fixing device fixing the pocket opening position of the garment, then the laser cutting device cutting it, after cutting, moving it above the accessory and having the pocket folding device fold it, then stacking the garment on the accessory, and finally moving it all to the sewing station for sewing. However, this technical solution cannot achieve continuous processing and has a high degree of manual intervention.

[0003] Chinese utility model patent CN214244833U discloses a continuous production garment pocket-opening machine. Based on the technical solution of CN111575926A, it adds a lower support plate below the pocket-folding device for placing accessories such as pocket flaps, pocket fabric, or zippers. The material-setting device has an upper plate mechanism that can clamp the lower support plate and move it towards the sewing device. A lower support plate reset device is provided on the worktable, which can transfer the lower support plate from the upper plate mechanism to below the pocket-folding device. This enables continuous processing.

[0004] However, in the above technical solutions, after the bag opening is folded, a shaping block is needed to maintain the fit between the bag opening and the accessories. At the same time, since the bag folding device is fixed above the accessory feeding area, the bag opening needs to be transported to the bag folding mechanism for folding after cutting. These factors will cause the bag eyebrow, bag cloth or zipper and other accessories to shift or move during the processing, thus affecting the stability of product quality. Summary of the Invention

[0005] The purpose of this invention is to provide a bag opening forming device for a bag opening machine, which integrates the folding mechanism and the material setting mechanism into one unit, thus solving the defects in the prior art where accessories such as bag flaps, bag fabric, and zippers are offset or displaced during processing, thereby affecting the stability of product quality.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows:

[0007] A bag opening forming device for a bag opening machine includes a folding mechanism and a material fixing mechanism; a base is provided, the folding mechanism and the material fixing mechanism are disposed on the base, and the folding mechanism is movably disposed above the material fixing mechanism;

[0008] The base is equipped with a Y-axis slide rail and a first drive mechanism, and the folding mechanism is equipped with a mounting seat. The mounting seat is connected to the Y-axis slide rail and slides along the Y-axis direction under the drive of the first drive mechanism.

[0009] The base is also equipped with a Z-axis connecting plate, through which the material setting mechanism is connected to the base;

[0010] The material setting mechanism is equipped with a small pressure frame and an outer pressure frame. The small pressure frame is located above the outer pressure frame, and the outer pressure frame and the small pressure frame are respectively equipped with bag opening processing windows. The outer pressure frame and the small pressure frame are mounted on the connecting plate in a height-adjustable manner.

[0011] The folding mechanism includes a blade holder, a blade assembly, a blade slide rail assembly, and a blade drive mechanism. The blade assembly consists of two X-axis blades and two Y-axis blades arranged in a rectangular shape. The blade slide rail assembly consists of an X-axis blade slide rail and a Y-axis blade slide rail. The blade drive mechanism includes an X-axis drive component that drives the two X-axis blades to open or return along the X-axis blade slide rail, and a Y-axis drive component that drives the two Y-axis blades to open or return along the Y-axis blade slide rail.

[0012] The mounting base is also equipped with a lifting slide rail in the Z-axis direction and a second drive mechanism. The tool holder is connected to the lifting slide rail and moves up and down along the Z-axis direction on the mounting base under the drive of the second drive mechanism.

[0013] An X-axis tool lifting component is also provided, and the X-axis tool is connected to the X-axis tool slide rail through the X-axis tool lifting component.

[0014] The first drive mechanism is a cylinder or a servo motor, and the X-axis drive component, Y-axis drive component, and X-axis tool lifting component are all cylinders or servo motors.

[0015] The bottom of the outer pressure frame is also equipped with a folding edge plate. The outer pressure frame is equipped with an opening drive unit that connects to the folding edge plate. The folding edge plate is equipped with a sewing window that cooperates with the bag opening processing window.

[0017] The opening section consists of two clamping arms that extend outward from both sides of the sewing window towards the inside of the outer pressing frame.

[0018] The opening drive unit is a cylinder.

[0019] The advantages of this invention are: 1. The folding mechanism and the material fixing mechanism are integrated, allowing for immediate folding of the bag opening fabric after cutting, thus preventing offset or displacement during transport; 2. The folding edge pressing plate setting of the material fixing mechanism further prevents deformation or displacement of the bag opening by fixing the folded edge of the bag opening after the folding process; 3. The integration of the folding mechanism and the material fixing mechanism shortens the length of the bag opening machine's worktable and the distance the bag opening fabric moves, which not only improves processing speed and efficiency but also reduces the size of the bag opening machine, saving space.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings. The drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent.

[0028] To simplify the description of this embodiment, some components that are well-known to those skilled in the art but are not related to the main content of this invention may be omitted in the accompanying drawings or description. Additionally, for ease of description, some components in the drawings may be omitted, enlarged, or reduced, but these do not represent the actual product dimensions or the complete structure.

[0029] A bag opening forming device for a bag opening machine, such as Figure 1 As shown, it includes a folding mechanism 2 and a material fixing mechanism 3; the folding mechanism 2 and the material fixing mechanism 3 are disposed on the base 1, and the folding mechanism 2 is movably disposed above the material fixing mechanism 3;

[0030] The base 1 is provided with a Y-axis slide rail 11 and a first drive mechanism 12. The folding mechanism 2 is provided with a mounting base 21. The mounting base 21 is connected to the Y-axis slide rail 11 and slides along the Y-axis direction under the drive of the first drive mechanism 12. Preferably, the first drive mechanism 12 can be a cylinder or a servo motor.

[0031] like Figure 2 , Figure 3 As shown, the folding mechanism 2 includes a blade holder 22, a blade assembly, a blade slide rail assembly, and a blade drive mechanism. The blade assembly consists of two X-axis blades 23 and two Y-axis blades 24 arranged in a rectangular shape. The blade slide rail assembly consists of an X-axis blade slide rail 231 and a Y-axis blade slide rail 241. The blade drive mechanism includes an X-axis drive component 232 that drives the two X-axis blades 23 to open or return along the X-axis blade slide rail 231, and a Y-axis drive component 242 that drives the two Y-axis blades 24 to open or return along the Y-axis blade slide rail 241.

[0032] Furthermore, an X-axis inserter lifting component 233 is provided, and the X-axis inserter 23 is connected to the X-axis inserter slide rail 231 through the X-axis inserter lifting component 233.

[0033] Preferably, the X-axis drive component 232, the Y-axis drive component 242, and the X-axis tool lifting component 233 can be configured as cylinders or servo motors.

[0034] like Figure 3 As shown, the mounting base 21 is also provided with a lifting slide rail 25 in the Z-axis direction and a second drive mechanism. The inserter seat 22 is connected to the lifting slide rail 25 and moves up and down along the Z-axis direction on the mounting base 21 under the drive of the second drive mechanism.

[0035] like Figure 1 , Figure 4 As shown, the base 1 is also provided with a Z-axis connecting plate 31, and the material fixing mechanism 3 is connected to the base 1 through the connecting plate 31;

[0036] like Figure 4As shown, the material setting mechanism 3 is provided with a small pressure frame 32 and an outer pressure frame 33. The small pressure frame 32 is located above the outer pressure frame 33. The outer pressure frame 33 and the small pressure frame 32 are respectively provided with bag opening processing windows 34. The outer pressure frame 33 and the small pressure frame 32 are raised and lowered on the connecting plate 31.

[0037] like Figure 4-6 As shown, the bottom of the outer pressure frame 33 is also provided with a folding edge pressing plate 36. The folding edge pressing plate 36 is provided with a sewing window 363 that cooperates with the bag opening processing window 34. The sewing window 363 is located below the processing window 34 and is connected to it. The connected part is the sewing part of the bag opening fabric piece.

[0038] The folded edge pressing sheet 36 can have various designs, such as Figure 5 , Figure 6 The diagram shows two design options, but it does not mean that the structure of the folded edge pressing sheet 36 of the present invention is limited to these two methods.

[0039] A design scheme such as Figure 5 As shown, the hem pressing plate 36 has a fixing part 361 on the outside of the sewing window 363, an opening part 362 on the inside of the sewing window 363, and an opening driving part 37 on the inside of the outer pressing frame 33. The fixing part 361 is fixedly connected to the bottom outer side of the outer pressing frame 33, and the two inner corners of the opening part 362 are connected to two opening driving parts 37 on the inside of the outer pressing frame 33. Preferably, the opening driving part 37 is a cylinder. The opening part 362 can separate (open) from the bottom of the outer pressing frame 33 under the drive of the opening driving part 37.

[0040] Another design scheme is as follows Figure 6 As shown, the opening portion 362 can also be configured as two clamping arms extending from both sides of the sewing window 363 toward the inner side of the outer pressure frame 33. The top ends of the two clamping arms are respectively connected to an opening drive portion 37. Under the drive of the opening drive portion 37, the clamping arms separate (open) from the bottom of the outer pressure frame 33.

[0041] When this invention is installed on a bag opening machine, the bag opening fabric is pressed between the outer pressure frame 33 and the small pressure frame 32 by the material fixing mechanism 3, and then transported to the laser cutting machine for bag opening cutting. After cutting, the folding mechanism 2 slides along the Y-axis direction above the material fixing mechanism 3 under the drive of the first drive mechanism 12. The second drive mechanism drives the insert knife group to insert into the processing window 34 of the material fixing mechanism 3. First, two Y-axis insert knives 24 are inserted into the processing window 34 and open along the Y-axis direction under the drive of the Y-axis drive component 242, opening and folding the long side of the cut of the bag opening fabric along the Y-axis direction. Subsequently, the X-axis insert knife lifting component 233 descends, and two X-axis insert knives 23 are inserted into the processing window 34 and open along the X-axis direction under the drive of the X-axis drive component 232, opening and folding the short side of the cut of the bag opening fabric along the X-axis direction, thus completing the folding process of the cut bag opening.

[0042] During the descent of the folding mechanism 2, the opening drive unit 37 of the outer pressure frame 33 drives the opening part 362 of the folding edge pressing plate 36 to move downward and separate from the bottom of the outer pressure frame 33, leaving space for the folding process of the folding mechanism 2. After the folding mechanism 2 completes the folding process, the opening drive unit 37 drives the opening part 362 to reset and press the bag opening folded edge tightly against the bottom of the outer pressure frame 33. The bag opening folded edge is pressed, stable and does not shift, which can ensure that the shape of the bag opening does not deform when the bag opening fabric is transported to the bag eyebrow, bag cloth or zipper and other accessory feeding station.

[0043] After the bag opening folding process is completed, the folding mechanism 2 returns to its initial position along the Y-axis under the drive of the first drive mechanism 12, that is, it withdraws from above the material setting mechanism 3.

[0044] In this way, after the bag opening fabric is cut, the bag opening is folded during the process of moving to the accessory feeding station. Compared with the existing technology, this not only shortens the processing time but also shortens the movement distance of the device, thus shortening the length of the bag opening machine's worktable.

[0045] The 36-folded edge pressing plate effectively fixes and maintains the shape of the bag opening after folding. Compared with the existing shaping pressing block, it has a simpler structure, better fixing and maintaining effect, and greatly reduces the defect rate of finished products.

[0046] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the invention. All equivalent changes and modifications made within the scope of the claims of this invention should be considered within the technical scope of this invention.
