Description

Technical Field

[0001] The utility model specifically relates to the technical field of fabric laser cutting, and specifically is a fabric laser cutting mechanism. Background Technique

[0002] A workpiece is heated by a laser beam with a high energy density, so that the temperature rises rapidly, reaches the boiling point of the material in a very short time, the material begins to vaporize and form vapor; using a laser for fabric cutting has the advantages of high efficiency and low cost. However, for some special fabrics, the existing laser cutting equipment and cutting processes cannot be used for cutting at present.

[0003] Currently, the traditional projection laser cutting device uses a projector to project the cutting route. However, limited by the irradiation range of the projector, multiple projectors need to be used for route projection. However, the adjacent two projectors are adjusted separately. In this way, when projecting, there will be a situation where the projected routes overlap or have gaps, and thus the laser cutting process cannot be effectively guaranteed.

[0004] After retrieval, Chinese Patent Application No. CN201820963704.2 discloses a large-format projection laser cutting device; it has a frame, the upper end of the frame is an open structure, a laser cutting component is embedded in the open structure of the frame, and a workbench is arranged at the lower end of the laser cutting component; a projection component is also fixedly arranged at the upper end of the frame; the projection component includes columns, a cross beam, a projector connecting plate and a high-definition projector; the columns are vertically arranged on both sides of the frame, the cross beam is horizontally arranged at the upper ends of the columns, the projector connecting plate is fixedly arranged in the middle of the cross beam, the high-definition projector is fixedly arranged on the projector connecting plate, and the lower end of the high-definition projector faces the workbench;

[0005] When the structure in the above patent cuts the fabric, the cutting route is irradiated by the projector above. Since the irradiation range of the projector has a certain range, when multiple projectors are used, the projected routes of the projectors will overlap or have gaps, and the accurate route movement of the laser cutting machine cannot be effectively guaranteed.

[0006] In view of the above situation, we provide a fabric laser cutting mechanism. In this device, multiple projectors are fixedly installed with a support component and a linkage component. In this way, when adjusting the projectors, it can effectively achieve equidistant projection adjustment among multiple projectors. When adjusting, an electric push rod drives one of the moving sliders to move effectively. At this time, the moving slider drives the first movable arm and the second movable arm or the third movable arm and the fourth movable arm to move simultaneously. The first connecting arm and the second connecting arm installed on the fixed block drive the two movable arms on the other moving slider to move simultaneously, achieving the effect of simultaneously adjusting multiple projectors, ensuring that the projection routes of adjacent two projectors will not overlap or have gaps, and ensuring that the moving component drives the laser cutting head to move along the correct cutting route; improving work efficiency.

Detailed implementation

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-6 , in the embodiment of the present invention, a fabric laser cutting mechanism includes a workbench 1; a plurality of projectors 4 are arranged on the top of the workbench 1; the projectors 4 are fixedly installed with a connecting arm 8 through a fixing connecting plate 9; the connecting arm 8 is fixedly installed with a supporting component 6; the supporting component 6 includes a support plate 60; a slide rail 61 is arranged on one side of the support plate 60; a plurality of moving sliders 65 are movably installed on the slide rail 61 and a fixing block 66 is fixedly installed; there are at least two moving sliders 65, and the fixing block 66 is arranged at the middle position of the moving sliders 65;

[0030] The fixing block 66 and the moving slider 65 are cooperatively installed through a linkage component 7; the linkage component 7 includes a first connecting arm 72 and a second connecting arm 73; the first connecting arm 72 and the second connecting arm 73 are installed on the fixing block 66 through a rotating shaft;

[0031] Specifically, a first movable arm 70 and a second movable arm 71 and a third movable arm 74 and a fourth movable arm 75 are respectively installed on the moving sliders 65 on both sides of the fixing block 66 through a rotating shaft; the first movable arm 70 is movably connected to the fourth movable arm 75 through the first connecting arm 72; the second movable arm 71 is movably connected to the third movable arm 74 through the second connecting arm 73;

[0032] By adopting the above technical solution, when in use, the fabric to be cut is placed on the workbench 1, and by adjusting the distance between the plurality of projectors 4, the cutting route can be effectively projected and irradiated, and then the moving component 2 drives the laser cutting head 3 to run along the route irradiated by the projector 4 to achieve the laser cutting effect;

[0033] The first movable arm 70, the second movable arm 71, the third movable arm 74 and the fourth movable arm 75 are all arranged in a V shape; the first connecting arm 72 and the second connecting arm 73 are arranged in a cross shape; by changing the opening angle of both ends of the first connecting arm 72 and the second connecting arm 73, the distance between the moving slider 65 and the fixed block 66 can be adjusted.

[0034] In this embodiment, one end of the slide rail 61, the moving slider 65 is fixedly installed with the electric push cylinder 62 through the connecting plate 64; the electric push cylinder 62 is fixedly installed with the support plate 60 through the fixing plate 63.

[0035] By adopting the above technical solution, when adjusting the distance between the projectors 4, the electric push cylinder 62 drives the connecting plate 64 fixedly installed with the moving slider 65 to move, so as to realize the approach or separation between the moving slider 65 and the fixed block 66. When adjusting, the third movable arm 74 and the fourth movable arm 75 are movably connected to the first movable arm 70 and the second movable arm 71 through the first connecting arm 72 and the second connecting arm 73. When the moving slider 65 connected to the connecting plate 64 approaches the fixed block 66, the openings at both ends of the first connecting arm 72 and the second connecting arm 73 open wide, so as to drive the other moving slider 65 to approach the fixed block 66. On the contrary, when the openings at both ends of the first connecting arm 72 and the second connecting arm 73 shrink, the two moving sliders 65 are separated from the fixed block 66.

[0036] In this embodiment, the connecting arm 8 is fixedly installed at the bottoms of the moving slider 65 and the fixed block 66; the connecting arms 8 installed on the moving slider 65 are symmetrically arranged.

[0037] One end of the connecting arm 8 far away from the moving slider 65 and the fixed block 66 is fixedly installed with a fixed connecting plate 9; the fixed connecting plate 9 is fixedly installed with the top of the projector 4.

[0038] By adopting the above technical solution, the first connecting arm 72 and the second connecting arm 73 are installed on the fixed block 66 through a rotating shaft, and are respectively movably connected to the first movable arm 70, the second movable arm 71, the third movable arm 74 and the fourth movable arm 75 at both ends. The lengths of the first movable arm 70, the second movable arm 71, the third movable arm 74 and the fourth movable arm 75 are the same. In this way, when moving, the distance between adjacent two projectors 4 can be effectively guaranteed to be the same. In this way, when the projector 4 irradiates the route, the situation of route overlap or vacancy will not occur, effectively ensuring that the moving component 2 drives the laser cutting head 3 to realize the cutting process of the irradiation route, and greatly improving the working efficiency.

[0039] In this embodiment, a moving component 2 is arranged on the workbench 1; the moving component 2 is fixedly installed with the laser cutting head 3.

[0040] By adopting the above technical solution, after the projection irradiation of the cutting route is completed, the moving component 2 drives the laser cutting head 3 to effectively move and cut along the projected route, ensuring that there is no deviation during laser cutting and guaranteeing the cutting quality.

[0041] The working principle of the present utility model is as follows: during use, the fabric to be cut is placed on the workbench 1. By adjusting the spacing between multiple projectors 4, the cutting route is effectively projected and irradiated. Then, the moving component 2 drives the laser cutting head 3 to run along the route irradiated by the projector 4 to achieve the laser cutting effect.

[0042] When adjusting the spacing between the projectors 4, the electric push rod 62 drives the connecting plate 64 fixedly installed with the moving slider 65 to move, realizing the approach or separation between the moving slider 65 and the fixed block 66. During the adjustment, the third movable arm 74 and the fourth movable arm 75 are movably connected to the first movable arm 70 and the second movable arm 71 through the first connecting arm 72 and the second connecting arm 73. When the moving slider 65 connected to the connecting plate 64 approaches the fixed block 66, the openings at both ends of the first connecting arm 72 and the second connecting arm 73 expand, driving the other moving slider 65 to approach the fixed block 66. Conversely, when the openings at both ends of the first connecting arm 72 and the second connecting arm 73 shrink, the two moving sliders 65 move away from the fixed block 66.

[0043] The first connecting arm 72 and the second connecting arm 73 are installed on the fixed block 66 through a rotating shaft and are respectively movably connected to the first movable arm 70 and the second movable arm 71 and the third movable arm 74 and the fourth movable arm 75. The first movable arm 70 and the second movable arm 71 are of the same length as the third movable arm 74 and the fourth movable arm 75. In this way, during movement, the spacing between adjacent two projectors 4 is effectively guaranteed to be the same. In this way, when the projector 4 irradiates the route, there will be no situation of route overlap or vacancy, effectively ensuring that the moving component 2 drives the laser cutting head 3 to realize the cutting process of the irradiated route, greatly improving the work efficiency.
