Description

Technical Field

[0001] This utility model relates to the field of micro-perforated mesh processing technology, specifically a micro-perforated mesh flattening and cutting device. Background Technology

[0002] Microporous mesh is a mesh material with numerous tiny pores, typically at the micrometer or even nanometer level. These tiny pores are evenly distributed on the mesh surface, giving the microporous mesh a large specific surface area. Its mesh structure can be regular or irregular, with common shapes including square and circular meshes. Microporous mesh is often used in fields with high dimensional accuracy requirements, such as electronics, medical, and precision instruments. Cutting devices can accurately cut the mesh according to predetermined dimensions, ensuring that the length, width, and shape of the microporous mesh meet design requirements. This avoids mismatches during subsequent assembly and use due to dimensional deviations, thus improving the overall quality and performance of the product.

[0003] The existing technology has the following problems:

[0004] Flat cutting devices typically employ automated control technology, enabling high-speed, continuous cutting operations that significantly improve production efficiency and reduce labor intensity. However, inaccurate cutting can lead to excessive scrap, increasing material costs. During the production and transportation of micro-perforated mesh, localized protrusions or depressions may occur, resulting in inaccurate cutting precision, uneven material, and scrap. Furthermore, when faced with different cutting requirements, it is impossible to finely adjust the horizontal and vertical directions of the cutting head independently, reducing the accuracy of the cutting dimensions.

[0023] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0024] like Figure 1-5 As shown, this utility model provides a microporous mesh flattening and cutting device, including a pressure flattening device 1. The pressure flattening device 1 can apply pressure to flatten the microporous mesh, which is convenient for subsequent cutting. Fixed connecting plates 3 are provided on the left and right rear sides of the pressure flattening device 1. The fixed connecting plates 3 can support the laser cutting device 2. The laser cutting device 2 is fixedly connected to the top of the two fixed connecting plates 3. The laser cutting device 2 is located above the top rear side of the pressure flattening device 1. The laser cutting device 2 can cut the microporous mesh from top to bottom.

[0025] like Figure 2As shown, this utility model provides a technical solution for a micro-perforated mesh flattening and cutting device: Preferably, the pressure flattening device 1 includes two vertically parallel pressure rollers 11. Both pressure rollers 11 are provided with component support plates 15 at their left and right ends. The bottom ends of the two component support plates 15 are fixedly connected to a fixed base 16. A flattening drive component 14 is provided inside the right component support plate 15. A horizontally penetrating movable slide groove 13 is provided above the middle of the right component support plate 15. A spacing adjustment component 12 is provided inside the movable slide groove 13. A conveyor roller 18 is provided parallel behind the lower pressure roller 11. The left and right ends of the conveyor roller 18 are rotatably connected to the opposite sides of two fixed connecting plates 3. A conveyor belt 17 is provided on the outer surface of the conveyor roller 18 and the lower pressure roller 11. The left end of the lower pressure roller 11 is rotatably connected to the right end of the left component support plate 15, and the left end of the upper pressure roller 11 is rotatably and slidably connected to the right end of the left component support plate 15.

[0026] Two parallel pressure rollers 11 are key components for leveling the microporous mesh. They are supported and positioned by component support plates 15 at the left and right ends and fixed on the base 16 to ensure the stability of the entire pressure leveling device. The component support plate 15 on the right side undertakes more functions. It is equipped with a leveling drive component 14 to provide power for the rotation of the pressure rollers. The moving slide 13 at the top center provides installation and movement space for the spacing adjustment component 12. When the microporous mesh is placed on the conveyor belt 17, the lower pressure roller 11 rotates under the drive of the leveling drive component 14. While squeezing the microporous mesh, it can also move the microporous mesh forward through the conveyor belt 17 in conjunction with the conveyor roller 18.

[0027] like Figure 3 As shown, this utility model provides a technical solution for a micro-perforated mesh flattening and cutting device: Preferably, the flattening drive assembly 14 includes a connecting rod 143, with drive worm gears 142 fixedly connected to both the upper and lower ends of the connecting rod 143. A drive motor 145 is provided at the bottom end of the lower drive worm gear 142, and the bottom end of the drive motor 145 is fixedly connected to the inside of the assembly support plate 15. The connecting rod 143 and the drive worm gear 142 are both rotatably connected to the inside of the assembly support plate 15. A movable [device] is meshed with the rear side of the upper drive worm gear 142. Adjusting worm gear 141 is located inside the movable slide groove 13. The lower drive worm gear 142 is meshed with a transmission worm gear 144 on its rear side. The left end of the transmission worm gear 144 extends to the outside of the component support plate 15 and is fixedly connected to the middle of the right end of the lower pressure roller 11. The left end of the movable adjusting worm gear 141 extends to the outside of the component support plate 15 and is fixedly connected to the middle of the right end of the upper pressure roller 11. Both the movable adjusting worm gear 141 and the transmission worm gear 144 are rotatably connected inside the component support plate 15.

[0028] As the power source for the entire leveling drive assembly 14, the drive motor 145, when started, drives the drive worm 142 to rotate simultaneously. The movable adjusting worm wheel 141 and the transmission worm wheel 144 begin to rotate under the drive of the drive worm 142, thereby transmitting the power of the drive motor 145 to the upper and lower pressure rollers 11, enabling them to rotate stably in opposite directions, extruding and outputting the passing microporous mesh. When the movable adjusting worm wheel 141 moves up and down under the control of the spacing adjustment assembly 12, due to the meshing connection between the movable adjusting worm wheel 141 and the drive worm 142, the movable adjusting worm wheel 141 will rotate during the movement, maintaining the meshing connection with the drive worm 142.

[0029] like Figure 3 As shown, this utility model provides a technical solution for a micro-perforated mesh flat cutting device: preferably, the movable adjusting worm gear 141 and the upper driving worm 142 are always engaged, and the length of the upper driving worm 142 is greater than that of the lower driving worm 142, and the upper driving worm 142 and the lower driving worm 142 rotate in opposite directions.

[0030] The upper drive worm 142 rotates in opposite directions to the lower drive worm 142, ensuring that the upper and lower pressure rollers 11 rotate in opposite directions so as to perform a flattening operation on the microporous mesh. Since the upper drive worm 142 is longer than the lower drive worm 142, it provides space for the movable adjusting worm wheel 141 to move within a certain range in the movable slide groove 13, so as to realize the spacing adjustment and maintain power transmission.

[0031] like Figure 3 As shown, this utility model provides a technical solution for a micro-perforated mesh flat cutting device: Preferably, the spacing adjustment component 12 includes an adjustment moving block 124, the inner side of the adjustment moving block 124 is rotatably connected to the left side of the outer surface of the moving adjustment worm gear 141, the outer surface of the adjustment moving block 124 is slidably connected to the inner side of the moving slide groove 13, the top center of the adjustment moving block 124 is rotatably connected to an adjustment threaded column 123, the top of the adjustment threaded column 123 extends to the outer side of the top of the component support plate 15, the outer surface of the adjustment threaded column 123 is threadedly connected to the inside of the component support plate 15, the top of the adjustment threaded column 123 is fixedly connected to a rotating disk 121, and the outer side of the top of the rotating disk 121 is fixedly connected to a rotating handle 122.

[0032] When it is necessary to adjust the distance between the upper and lower pressure rollers 11 to accommodate microporous meshes of different thicknesses, the operator holds the rotating handle 122 and rotates the rotating disk 121. Since the adjusting threaded column 123 is threadedly connected to the component support plate 15, when the rotating disk 121 drives the adjusting threaded column 123 to rotate, the adjusting threaded column 123 will move up and down within the component support plate 15. The up and down movement of the adjusting threaded column 123 will drive the adjusting moving block 124 to slide up and down within the moving slide groove 13, thereby pushing the moving adjusting worm gear 141 to move up and down within the moving slide groove 13, thus realizing the adjustment of the distance between the upper and lower pressure rollers 11.

[0033] like Figure 4 As shown, this utility model provides a technical solution for a micro-perforated mesh flat cutting device: preferably, the laser cutting device 2 includes a cutting and fixing frame 22, the bottom end of the cutting and fixing frame 22 is fixedly connected to the top of two fixed connecting plates 3, the cutting and fixing frame 22 is located above the conveyor belt 17, a moving positioning device 21 is provided inside the cutting and fixing frame 22, and a laser emitting device 23 is fixedly connected to the moving base of the moving positioning device 21.

[0034] The cutting and fixing frame 22 ensures the stable installation of the entire laser cutting device 2 in the device. Located above the conveyor belt 17, it provides a suitable position for cutting the micro-perforated mesh on the conveyor belt 17. The moving positioning device 21 moves the laser emitting device 23, which is fixedly connected to its moving base, in the horizontal and vertical directions according to the preset cutting path or the operator's instructions, so that the laser emitting device 23 can be positioned at the position where the micro-perforated mesh needs to be cut.

[0035] The operation of the mobile positioning device 21 depends on its functional design and is existing technology, so it will not be explained here.

[0036] like Figure 5As shown, this utility model provides a technical solution for a micro-perforated mesh flat cutting device: Preferably, the laser emitting device 23 includes a fixing plate 231, which is fixedly connected to the moving base of the moving positioning device 21. A fixing guide block 232 is fixedly connected to the front end of the fixing plate 231. A limiting guide groove 234 is opened in the middle of the front end of the fixing guide block 232. A moving connecting block 235 is slidably connected to the inner side of the limiting guide groove 234. A vertical fine-tuning threaded column 233 is threadedly connected to the rear end of the moving connecting block 235. The bottom end of the vertical fine-tuning threaded column 233 is rotatably connected to the bottom of the inner side of the limiting guide groove 234. The top end of the vertical fine-tuning threaded column 233 extends... A connecting moving block 237 is provided in front of the fixed guide block 232, and a transverse moving space groove 238 is provided behind the connecting moving block 237 for the moving connecting block 235 to move left and right. The front end of the moving connecting block 235 slides inside the transverse moving space groove 238. The front end of the moving connecting block 235 is threaded to the left and right sides with transverse fine-tuning threaded posts 236. The left end of the transverse fine-tuning threaded posts 236 extends to the outer side of the left end of the connecting moving block 237. The right end of the transverse fine-tuning threaded posts 236 is rotatably connected to the right end of the inner side of the transverse moving space groove 238. A laser cutting head 239 is fixedly connected to the bottom end of the connecting moving block 237.

[0037] The fixed plate 231 provides a stable mounting base for the entire laser emitting device 23, and the limiting guide groove 234 provides a vertical sliding track for the movable connecting block 235. When it is necessary to adjust the vertical position of the laser cutting head 239, rotating the vertical fine-tuning threaded column 233 will cause the movable connecting block 235 to slide up and down within the limiting guide groove 234. The up and down movement of the movable connecting block 235 will drive the connecting moving block 237 and the laser cutting head 239 to adjust their vertical positions together, thereby achieving the vertical position adjustment of the laser cutting head 239. Precise fine-tuning is used to meet the cutting needs at different heights or to adjust the laser focusing position according to actual conditions. When it is necessary to adjust the lateral position of the laser cutting head 239, the operator rotates the lateral fine-tuning threaded column 236. The thread action causes the movable connecting block 235 to slide left and right in the lateral moving space groove 238. Since the movable connecting block 235 cannot move left and right under the limit of the limiting guide groove 234, the moving block 237 will move laterally through the reaction force, thereby achieving precise fine-tuning of the lateral position of the laser cutting head 239.

[0038] The working principle of this microporous mesh flattening and cutting device will be explained in detail below.

[0039] like Figure 1-5As shown, based on the thickness of the microporous mesh, the rotating handle 122 of the rotation spacing adjustment component 12 drives the adjusting threaded column 123 to rotate, causing the adjusting moving block 124 to push the moving adjusting worm gear 141 to adjust the distance between the upper and lower pressure rollers 11. The drive motor 145 of the flattening drive component 14 is started, driving the drive worm 142 to rotate the moving adjusting worm gear 141 and the transmission worm gear 144. The upper and lower pressure rollers 11 rotate in opposite directions to flatten the protrusions or depressions of the placed microporous mesh. After the flattened microporous mesh moves to below the laser cutting device 2, the drive motor 145 stops. The moving positioning device 21 of the laser cutting device 2 drives the laser emitting device 23 to position the cutting position according to the instruction. The laser emitting device 23 emits laser light, which is finely adjusted by components such as the fixed plate 231, the vertical fine-tuning threaded column 233, and the horizontal fine-tuning threaded column 236 to accurately cut the microporous mesh.

[0040] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
