Description

Technical Field

[0001] The utility model belongs to the field of laser cutting, and particularly relates to a laser cutting device for a filter component. Background Art

[0002] In the production process of filter components, the cutting quality of the filter screen is crucial.

[0003] However, the problem of unevenness before cutting the filter screen will seriously affect the cutting quality, and the specific manifestations are as follows: dimensional deviation: when there are local protrusions or depressions on the filter screen, the laser cutting head operates according to the preset program, and there will be a deviation between the actual cutting position and the ideal position, resulting in the size of the cut filter screen not meeting the requirements, thereby affecting subsequent assembly and use; shape error: the unevenness of the filter screen will cause different effects of the laser at different positions. The protruded part may be over-cut due to concentrated laser energy, while the sunken part may be under-cut due to insufficient laser energy, ultimately resulting in an irregular shape of the cut filter screen and unable to meet the designed shape accuracy standard; rough cut: during the cutting process of the uneven filter screen, the melting and vaporization of the material are uneven. At the uneven places, the laser energy is unevenly distributed, resulting in defects such as serrations and burrs at the cut, increasing the surface roughness of the cut. This not only affects the filtering performance of the filter screen but also reduces its service life; increased slag: due to the unstable cutting process, the melt at the uneven part cannot be smoothly blown away from the cutting area by the auxiliary gas, and it is more likely to form slag residues near the cut, further reducing the quality of the cutting surface;

[0004] Therefore, a laser cutting device for filter components is needed to solve the above problems. Summary of the Utility Model

[0005] The purpose of the embodiment of the utility model is to provide a laser cutting device for filter components to solve the problems put forward in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A laser cutting device for filter components includes a cutting component, two first support rollers, a unwinding component, a winding component, a second support roller, a pressing component, and a positioning and fixing component. The cutting component includes a workbench and a cutting piece, and the cutting piece (12) is fixedly connected to the upper surface of the workbench (11);

[0030] The two first support rollers 2 and the second support roller 6 are rotatably connected in the workbench 11;

[0031] The unwinding component 3 is connected to the back of the workbench 11, and the winding component 5 is connected to the front of the workbench 11. A filter screen 4 is wound around both the unwinding component 3 and the winding component 5;

[0032] The pressing component 7 includes a connecting frame 71 and a plurality of guide rods 73. The plurality of guide rods 73 are connected to the upper surface of the workbench 11.

A spring 74 is sleeved outside the guide rod 73, and the two ends of the spring 74 are respectively connected to the guide rod 73 and the workbench 11.

[0033] In this embodiment, when one end of the filter screen 4 wound around the unwinding component 3 passes through between the pressure roller 72 and the first support tube, and then both sides of the filter screen 4 are located inside the movable frame 83, and then one end of the filter screen 4 is fixed outside the rotating roller in the winding component 5. Due to the connecting frame 71 driving the pressure roller 72 to press the filter screen 4 under the action of the elastic force of the plurality of springs 74, the filter screen 4 is in a taut state, and the filter screen 4 pulled out from between the pressure roller 72 and the first support roller 2 can be leveled, so that the filter screen 4 moving onto the workbench 11 is in a flat state. Then, control the cutting member 12 to work, and the working cutting member 12 cuts the flat filter screen 4;

[0034] When the filter screen 4 is a woven filter screen 4 and a plastic filter screen 4, the taut filter screen 4 can ensure flatness; when the filter screen 4 is a metal filter screen 4, the metal filter screen 4 can be pressed flat under the action of the pressure roller 72 and the first support roller 2;

[0035] When the filter screen 4 moving onto the workbench 11 is cut, control the winding component 5 and the unwinding component 3 to work. The working winding component 5 winds up the cut filter screen 4, and the filter screen 4 wound around the unwinding roller continues to pass through between the pressure roller 72 and the first support roller 2 and moves onto the workbench 11.

[0036] Specifically, two first support rollers 2 are arranged between the second support roller 6 and the unwinding assembly 3, the second support roller 6 is arranged between the winding assembly 5 and the first support roller 2, and the tops of the first support roller 2 and the second support roller 6 are on the same plane as the upper surface of the workbench 11.

[0041] Embodiment 2

[0042] Please refer to Figures 1 - 4 , the difference between this embodiment and Embodiment 1 is that: it further includes a positioning and fixing assembly 8. The positioning and fixing assembly 8 includes a plurality of support seats 81. A first cylinder 82 is connected inside each of the plurality of support seats 81. One ends of the plurality of first cylinders 82 close to each other are respectively connected to the two movable frames 83. A plurality of first rollers 84 are rotatably connected to one side of the two movable frames 83 close to each other. A plurality of second cylinders 85 are connected inside the two movable frames 83. The bottoms of the plurality of second cylinders 85 are connected to the two pressing plates 86. A plurality of second rollers 87 are rotatably connected inside the two pressing plates 86; the shape of the movable frame 83 is set to be L-shaped.

The two approaching movable frames 83 drive a plurality of first rollers 84 to respectively contact both sides of the filter screen 4. At this time, the two pressing plates 86 move above the filter screen 4. Control the plurality of second cylinders 85 to extend. The two moving pressing plates 86 drive a plurality of second rollers 87 to contact the upper surface of the filter screen 4. At this time, the filter screen 4 moving onto the workbench 11 can be positioned and pressed, so that the filter screen 4 is not likely to be displaced during the cutting process. And when the winding assembly 5 winds the cut filter screen 4, the filter screen 4 limited and fixed by the two positioning and fixing assemblies 8 can be smoothly wound outside the winding assembly 5. And during this process, the filter screen 4 is not likely to shift;

[0044] Moreover, since the distance between the two movable frames 83 is adjustable, the two movable frames 83 can position the filter screens 4 with different widths. Since the distance between the pressing plate 86 and the workbench 11 is adjustable, the moving pressing plate 86 can press and fix the filter screens 4 with different thicknesses on the workbench 11.

[0045] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
