It can efficiently remove burrs, uneven parts or excess materials on the edge of the wire mesh, making the edge of the wire mesh neater and smoother, thereby improving the product quality and appearance aesthetics. To ensure the welding quality, a rough edge is left when welding the wire mesh, and then the rough edge is trimmed manually or cut off with a guillotine shear. Manual trimming is time-consuming and laborious. When using a guillotine shear to cut the wire mesh, if the wires of the wire mesh are not straight, the wire mesh will be damaged, and the trimmed wire mesh has burrs and is easy to cut hands.

[0003] In the existing wire mesh trimming technology, for example, the prior art with the application number CN201720404853.0 includes a mounting plate, an anvil, a lower blade, a counterweight, a connecting plate, an adjusting handwheel, a crank connecting rod, a support column, a crank seat, a flywheel, a guide cylinder and a vertical knife seat, etc. The driving motor and the crank seat are respectively fixedly installed on the rear side and the front side of the lifting seat.

The structure is simple, easy to manufacture, easy to operate, time-saving and labor-saving, fast in speed, high in efficiency and good in trimming effect.

[0004] However, the prior art is not convenient for automatic stacking, automatic trimming and automatic palletizing. And when trimming a wire mesh with uneven wires, the wire mesh is easily damaged, resulting in reduced practicability. Moreover, the prior art is not convenient for grasping the wire mesh.

And when trimming a wire mesh with uneven wires, the wire mesh is not easily damaged, resulting in reduced practicability. Moreover, the efficiency and quality of grasping the wire mesh are relatively high, and the trimming efficiency is improved.

The two units work together. The warp fluff can be trimmed first, and then the weft fluff can be trimmed, realizing assembly line operation.

[0052] Such as Figures 1 to 9As shown in the figure, when the automatic edge trimming machine of the utility model is working, when loading and unloading the wire mesh 81, by turning on the second motor 16, the grasping lifting manipulator 15 is driven to descend due to the meshing relationship between the second gear and the second rack. Then, the grasping mechanism 02 contacts the wire mesh 81 to complete the grasping and fixing of the wire mesh 81. After that, the second motor 16 is reversed to raise the grasping lifting manipulator 15. Then, by turning on the first motor 14, the moving slide plate slides on the adjusting frame 13 due to the transmission relationship between the gear and the rack. When the wire mesh 81 is located on the edge trimming workbench 12, the second motor 16 is controlled to lower the grasping lifting manipulator 15, and the grasping mechanism 02 is controlled to place the wire mesh on the edge trimming workbench 12. When grasping, the first cylinder 26 is in the pushed-out state, and the magnet seat 29 is higher than the bottom surface of the retaining net plate 27. By turning on the second motor 16 to drive the grasping lifting manipulator 15 to descend, the magnet 291 contacts the wire mesh 81. Then, the second motor 16 is reversed to drive the grasping lifting manipulator 15 to rise, and the wire mesh 81 in contact with the magnet 291 will be firmly attracted by the magnet 291 and rise together to achieve grasping and stacking. When placing the wire mesh, the first cylinder 26 retracts, driving the magnet seat 29 to slide within the retaining net plate 27, thereby causing the magnet 291 to retract into the retaining net plate 27 and separating the magnet 291 from the wire mesh 81, and the wire mesh 81 drops to achieve the placement of the wire mesh 81. The designed mechanism is simple, low in cost, and easy to install. After the wire mesh 81 is placed on the edge trimming workbench 12, the third cylinder 34 is turned on to drive the sliding block 33 to slide within the slideway of the edge trimming workbench 12, thereby driving the limiting roller 35 to limit the wire mesh front and back. Then, by turning on the second cylinder 31 to drive the limiting push plate 32 to limit the wire mesh left and right. Then, by turning on the fourth cylinder 42 to drive the pressing plate 43 to fix the wire mesh on the edge trimming workbench 12, improving the stability of edge trimming. After the wire mesh 81 is fixed, the fifth cylinder 58 operates to push the sliding cutter seat 54 to slide on the linear bearing track 53 until the moving cutter tail 631 approaches the wire mesh 81. With the assistance of the protection mechanism 07, by turning on the servo motor 52 to drive the third gear to rotate, and then driving the servo tool carriage 51 to slide on the working frame 11 through the meshing relationship, thereby adjusting the position of edge trimming front and back, so that the fixed cutter 62 and the moving cutter 63 move to the position to be cut. The servo reduction motor 64 operates to drive the turntable to rotate, and then drives the eccentric shaft to pull the connecting rod, causing the moving cutter 63 to move up and down once to cooperate with the fixed cutter 62 to cut off the burrs of the wire mesh 81. The servo motor 52 then moves to find the next burr position and cycles in turn to finish trimming the burrs of all wire meshes 81. The fifth cylinder 58 operates to withdraw the cutting mechanism 06 from the wire mesh 81. Since there is a protection spring 73 in front of the fifth cylinder 58, the moving cutter tail 631 and the wire mesh 81 are in flexible contact. When the servo tool carriage 51 slides and travels, even if the wire mesh 81 is not straight, the cutter will travel along the concave and convex trajectory of the wire mesh 81 and will not damage the wire mesh.

[0053] Two units can work in tandem. The warp yarn frayed ends can be trimmed first, followed by the weft yarn frayed ends. It operates in an assembly line manner, improving the efficiency of automatic edge trimming. There are an upper cutter and a lower cutter for trimming the frayed ends of the warp and weft yarns.

[0054] The first motor 14, the second motors 16, 36, the second cylinder 31, the third cylinder 34, the fourth cylinder 42, the servo motor 52, the servo reduction motor 64 and the fifth cylinder 58 of the present utility model are purchased on the market. Those skilled in the art only need to install and operate them according to the attached operation manuals, without the need for creative labor from those skilled in the art.

[0055] The main functions achieved by the present utility model are as follows: during the netting edge trimming process, it facilitates automatic stacking, automatic edge trimming and automatic palletizing. When trimming a netting with uneven netting yarns, the netting is not easily damaged, reducing its practicality. Moreover, the netting grasping efficiency and quality are relatively high, improving the edge trimming efficiency.

[0056] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
