Description

Technical Field

[0001] This utility model relates to the field of garment processing technology, specifically a laser bag opening machine with ironing function. Background Technology

[0002] In garment manufacturing, pocket opening machines are essential auxiliary processing machinery, mainly used to create pockets in specific locations on garments for carrying small items such as mobile phones and wallets. The conventional approach is to process the pocket opening and lip separately first, and then sew the lip onto the opening to complete the pocket opening.

[0003] The bag opening process involves cutting, folding, shaping, and sewing the bag opening. Cutting involves making two "Y"-shaped or "I"-shaped slits at the bag opening. Folding involves folding the cut bag opening inward to form a folded edge. Shaping involves placing the bag lip on the folded edge. Finally, the bag is sewn together.

[0004] However, currently, during the sewing stage, because there are no obvious creases on the pocket edges, the pocket edges may shrink or become defective or burst during the process from when the pocket is folded until it reaches the sewing mechanism, resulting in defects in the sewn pocket.

[0005] Therefore, how to shape the folded edge of the pocket became the problem that needed to be solved in this case. Based on this, this case came into being. Summary of the Invention

[0028] This utility model embodiment provides a laser bag opening machine with ironing function, such as Figure 1-7 As shown, the machine includes a frame 10 with a worktable 11. A laser cutting mechanism 12, a sewing mechanism 13, and a folding mechanism 7 are provided on the frame 10 corresponding to the worktable 11. A movable or fixed substrate 1 and the folding mechanism 7 are also provided on the frame 10. When the substrate 1 and the folding mechanism 7 are movable, the frame 10 is provided with a substrate moving mechanism for moving the substrate 1 and a cutting tool moving mechanism for moving the folding mechanism 7. This is prior art; for the bag opening machine structure, please refer to an automatic bag opening machine with publication number CN220724510U. The substrate moving mechanism described in this application is consistent with the transverse moving mechanism in the aforementioned references. When the substrate moving mechanism is a screw and slide rail assembly, the moving nut on the screw and slide rail is connected to the substrate transverse moving platform 14, and the substrate 1 is connected through the substrate transverse moving platform 14.

[0029] The substrate 1 is equipped with a pressing frame assembly, a material fixing assembly, and a folding assembly. The material fixing assembly and the folding assembly are arranged vertically from a frontal view, and the two mechanisms do not interfere with each other when operating in a planar manner. The material fixing assembly is located above the folding assembly. A rectangular slot 3 is provided on the substrate 1 for opening the bag. The blades on the material fixing assembly and the folding assembly correspond to the front and rear sides of the slot.

[0030] For the specific structure of the frame pressing assembly, the material fixing assembly, and the material folding assembly, please refer to the genuine pocket sewing process of a laser bag opening machine published in CN120099726A.

[0031] The material positioning assembly includes an outer material positioning blade, an inner material positioning blade, and two sets of material positioning drive components. The outer material positioning blade is C-shaped, and the outer and inner material positioning blades correspond to the front and rear sides of the through slot. After the outer and inner material positioning blades are combined, a rectangular slot is formed in the middle. The length of the rectangular slot is the width of the largest "Y" or "I" shaped cut. The two sets of material positioning drive components are used to drive the outer and inner material positioning blades to move axially towards the front and rear sides of the through slot. The material positioning drive components include a material positioning driver and a material positioning connecting rod. The material positioning driver can be a material positioning blade cylinder or other modules that can achieve linear drive function, such as a lead screw and slide rail module. The material positioning driver is mounted on the base plate and is connected to the outer or inner material positioning blade through the material positioning connecting rod. Multiple material positioning connecting rods can be provided. In this embodiment, each set has two material positioning connecting rods, which are arranged at right angles and connected end to end. The base plate is provided with a guide groove for the axial displacement of the material positioning connecting rods.

[0032] The material handling assembly includes an outer pulling blade, an inner pulling blade, and two sets of pulling drive components. The outer and inner pulling blades have slots for inserting cutting tools. The two sets of pulling drive components drive the outer and inner pulling blades to move axially towards the front and rear sides of the through slot. Each pulling drive component includes a pulling driver and a pulling linkage. The pulling driver can be a pulling cylinder or other modules capable of linear drive, such as a lead screw and slide rail module. The pulling cylinder is mounted on the base plate and connected to either the outer or inner pulling blade via the pulling linkage. Two pulling cylinders can be used to drive the outer pulling blade, with each cylinder positioned on one side of the outer pulling blade. The output ends of the two cylinders are connected to the two ends of the outer pulling blade via the pulling linkage.

[0033] The outer and inner pull blades are equipped with guide plates at their tails. A guide groove is axially opened on the guide plate. A sliding shaft that can slide in the guide groove is fixed on the base plate. The pull drive is connected to the guide plate through the pull linkage.

[0034] To reduce the weight at the far end of the substrate, the stationary cutting cylinder and the pulling cylinder are positioned at the end of the substrate close to the substrate moving mechanism and arranged axially. In addition, the elimination of two sets of stationary cutting blades and pulling blades makes the weight of the substrate far from the bearing end smaller, and the far end of the substrate is less likely to sink and deform, thus improving the performance of the substrate.

[0035] The pressure frame assembly includes a pressure frame platform, a pressure strip platform, an outer pressure frame, an outer pressure strip, an inner pressure strip, a pressure strip cylinder, and a tension spring. A second guide rail is vertically mounted on the base plate. The pressure frame platform slides onto the second guide rail via a slider. A driver is provided on the base plate to drive the pressure frame platform's lifting and lowering. The driver can be a cylinder, a lead screw and slide rail module, or other modules that achieve linear movement. To improve the stability of the pressure strip platform during lifting and lowering, a first guide rail is provided on the pressure frame platform. The pressure strip platform slides onto the first guide rail via a slider. The outer pressure frame is mounted on the pressure frame platform, and the pressure strip cylinder is mounted on the pressure strip platform and is used to drive the inner pressure strip's lifting and lowering. The outer pressure strip is located at the bottom of the outer pressure frame and corresponds to the inner pressure strip front and back.

[0036] The pressing strip plate and the pressing frame plate are connected by a tension spring. The tension spring consists of a sleeve containing a spring. A through hole is formed in the pressing strip plate, and the sleeve is fixedly fitted over the through hole. The spring inside passes through the through hole and is connected to the pressing frame plate. The tension spring provides tension to the pressing strip plate, enabling it to press the fabric firmly.

[0037] The outer and inner pressure strips are located above the through groove. The outer pressure strip is used to secure the front side of the bag, and the inner pressure strip is used to secure the back side of the bag.

[0038] For the specific structure of the folding mechanism 7, please refer to the true pocket sewing process of a laser bag opening machine published in CN120099726A.

[0039] An ironing mechanism is installed on one of the following carriers: substrate 1, frame 10, or worktable 11. It is not limited to these three carriers.

[0040] Example 1, as Figure 1-3 As shown, when the ironing mechanism is set on the substrate 1, it is ironing mechanism 4. Ironing mechanism 4 includes cylinder 41, movable carrier 42, guide rail 43, slider 44 that is slidably adapted to the guide rail 43, cylinder 45, support frame 46, and pressure plate 47. Cylinder 41 and guide rail 43 are both longitudinally arranged on the transverse platform 14 of the substrate. The output end of cylinder 41 is connected to movable carrier 42, and movable carrier 42 is connected to slider 44. Cylinder 45 is vertically arranged on movable carrier 42, and its output end is connected to support frame 46. Pressure plate 47 is arranged at the bottom of support frame 46 and can correspond vertically to the through groove 3 on substrate 1. Cylinder 41 is used to drive the movable carrier 42 to move longitudinally. Under normal conditions, it can bring the pressure plate 47 to the rear of the through groove 3 to avoid interfering with the insert knife when folding the material. Cylinder 41 can drive the pressure plate 47 to the upper position of the through groove 3, and then the pressure plate 47 is driven down into the through groove 3 by cylinder 45 to iron the folded fabric. The size of the pressure plate 47 is slightly smaller than that of the through groove 3, and it is fitted with the through groove 3 with a clearance.

[0041] A heating mechanism is arranged on the top or inside of the pressure plate 47. The heating mechanism can be an electric heating wire 48. The electric heating wire 48 adopts a reciprocating serpentine arrangement or a ring-shaped involute arrangement. The pressure plate 47 is made of metal and is heated by the electric heating wire 48 to achieve the ironing function.

[0042] The heating mechanism can also be steam ironing. A cavity is set inside the pressure plate 47. The bottom of the pressure plate 47 corresponding to the through groove 3 is provided with dense through holes for steam to be released. The top or side of the pressure plate 47 is used to receive steam, and the fabric is ironed by steam ironing.

[0043] Example 2, as Figure 4-5 As shown, when the ironing mechanism is set on the frame 10, it is ironing mechanism two 5. The preferred embodiment of ironing mechanism two 5 is arranged between the folding mechanism 7 and the laser cutting mechanism 12, but it can also be set in other areas. Ironing mechanism two 5 includes a support beam 51, a cylinder three 52, a support frame two 53, and a pressure plate two 54. The support beam 51 is fixed on the frame 10 and extends above the worktable 11. The cylinder three 52 is vertically fixed on the support beam 51, and its output end is connected to the support frame two 53. The pressure plate two 54 is located at the bottom of the support frame two 53, and the pressure plate two 54 corresponds vertically to the through groove 3 on the base plate 1. The cylinder three 52 is used to drive the pressure plate two 54 down into the through groove 3. The structure of the pressure plate two 54 is the same as that of the pressure plate one 47, and will not be described again.

[0044] A heating mechanism 2 is arranged on the top or inside of the pressure plate 2 54. The heating mechanism 2 can be an electric heating wire 2 55. The arrangement of the electric heating wire 2 55 is the same as that of the electric heating wire 1 48, and will not be described in detail here. The heating mechanism 2 can also adopt the steam ironing function of Embodiment 1.

[0045] Example 3, as Figure 6-7 As shown, when the ironing mechanism is set at the bottom of the worktable 11, it is ironing mechanism three 6. Ironing mechanism three 6 includes a support plate 61, a cylinder four 62, a support frame three 63, and a pressure plate three 64. The support plate 61 is set at the bottom of the worktable 11. The cylinder four 62 is vertically set on the support plate 61, and its output end is connected to the support frame three 63. The pressure plate three 64 is set at the top of the support frame three 63. The worktable 11 has a pressure plate groove through which the pressure plate three 64 can pass. The pressure plate three 64 corresponds vertically to the through groove 3 on the base plate 1. Under normal conditions, the pressure plate three 64 is in the pressure plate groove and is flush with the upper surface of the worktable 11. During ironing, the cylinder four 62 drives the pressure plate three 64 to rise, so that it irons the fabric in the through groove 3.

[0046] A heating mechanism 3 is arranged on the top or inside of the pressure plate 3 64. The heating mechanism 3 can be an electric heating wire 3 65. The arrangement of the electric heating wire 3 65 is the same as that of the electric heating wire 1 48, and will not be described in detail here. The heating mechanism 3 can also adopt the steam ironing function of Embodiment 1.

[0047] It should be noted that only one ironing mechanism should be installed on the same machine, that is, one of the three embodiments above is sufficient.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
