Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] Please refer to Figure 1 A wind knife assembly provided in an embodiment of the utility model includes: a wind knife 10, an anti-collision net assembly 20 and a fastener. A connecting portion 11 is provided at the upper end of the wind knife 10. The wind knife 10 is a cylindrical structure. The wind knife 10 is preferably made of SUS316 material. In addition, it can also be made of other types of stainless steel. The anti-collision net assembly 20 includes a bracket 21 and an anti-collision net 22. The bracket 21 is provided with a mounting hole corresponding to the connecting portion 11. The anti-collision net 22 is connected to the bracket 21, wherein a blade is provided on one side of the wind knife 10, and the anti-collision net 22 is located on one side of the blade of the wind knife 10. The bracket 21 is detachably connected to the connecting portion 11 through fasteners and mounting holes. The connection part 11 may be an internal threaded hole arranged at one end of the wind knife 10, and the fastener may be a screw. When installing, the bracket 21 is placed above the connection part 11 of the wind knife 10, and the mounting hole corresponds to the internal threaded hole, and then the screw passes through the mounting hole from top to bottom and is connected in the threaded hole. The screw may be a hexagon socket screw; or the connection part 11 may be a connecting column arranged at one end of the wind knife 10, and the outer diameter of the connecting column is not larger than the mounting hole and smaller than the outer diameter of the wind knife 10. When installing, the mounting hole on the bracket 21 is sleeved on the connecting column, wherein the end of the connection part 11 passing through the mounting hole is provided with an external thread, and the fastener may be a nut, which is connected to the external thread on the connecting column. When the wind knife 10 needs to be replaced and maintained, the fastener may be removed from the connection part 11, and then the bracket 21 may be lifted out of the connection part 11. Finally, the wind knife 10 may be removed from the wind knife device by acting on the connection part 11 with a screwing tool. When installing, the reverse operation steps may be performed. Since the anti-collision net 22 can be disassembled and assembled from the top during the disassembly and assembly process, the convenience of disassembly and assembly of the anti-collision net 22 can be improved. In addition, when disassembling and assembling the wind knife 10, there is no need to clamp the body of the wind knife 10 for screwing, so the convenience of disassembly and assembly of the wind knife assembly can be effectively improved, and the wind knife 10 will not be damaged, thereby effectively ensuring the service life of the wind knife 10.
[0033] In some embodiments, the mounting hole is a first waist-shaped hole 2121, and the bracket 21 can move relative to the wind knife 10 to adjust the position of the anti-collision net 22 relative to the wind knife 10, thereby improving its application flexibility, wherein the moving direction of the bracket 21 is the length extension direction of the first waist-shaped hole 2121, and the fastener can fix the connecting part 11 at any position of the first waist-shaped hole 2121. Specifically, after the bracket 21 moves to the target position relative to the wind knife 10, it can be fixed by the fastener.
[0034] In some embodiments, the bracket 21 includes a fixed frame 211 and a movable plate 212, the fixed frame 211 is provided with a second waist-shaped hole 2111, the length of the second waist-shaped hole 2111 is perpendicular to the length extension direction of the first waist-shaped hole 2121, one end of the movable plate 212 can be fixed at any position of the second waist-shaped hole 2111 by a locking member, the first waist-shaped hole 2121 is provided on the movable plate 212, wherein the locking member is preferably a bolt. The position of the bracket 21 in the plane can be effectively adjusted through the first waist-shaped hole 2121 and the second waist-shaped hole 2111, so that the installation of the bracket 21 can be effectively facilitated. Furthermore, a step surface is provided on one end of the movable plate 212 facing the fixed frame 211, and the side surface of the step surface contacts the side surface of the fixed frame 211 to prevent the movable plate 212 from rotating relative to the fixed frame 211, thereby ensuring the accuracy of the relative position of the anti-collision net 22 and the wind knife 10. Specifically, the bottom surface of the step surface of the movable plate 212 can contact the lower surface of the fixed frame 211, and the side surface of the step surface contacts the side surface of the fixed frame 211, thereby limiting the freedom of the movable plate 212 relative to the fixed frame 211211.
[0035] In some embodiments, Figure 1~Figure 3 As shown, the wind knife assembly includes two groups of wind knives 10, the two groups of wind knives 10 are arranged parallel to each other and the air outlets of the two groups of wind knives 10 are arranged opposite to each other, and the anti-collision net assembly 20 includes two groups of anti-collision nets 22, the two groups of anti-collision nets 22 are connected to the bracket 21, and the two groups of anti-collision nets 22 are located between the two groups of wind knives 10. When working, the workpiece 30 can pass through the channel between the two groups of anti-collision nets 22, and the two groups of wind knives 10 blow air on both sides of the workpiece 30.
[0036] In some embodiments, Figure 1 As shown, the fixing frame 211 is an I-shaped plate structure, and the middle plate of the I-shaped plate structure is installed on the two groups of wind knives 10. For example, two second waist-shaped holes 2111 arranged parallel to each other can be set on the middle plate, and one second waist-shaped hole 2111 corresponds to a movable plate 212. The two groups of anti-collision nets 22 are respectively installed on the two horizontal plates of the I-shaped plate structure. The two horizontal plates have the same length and width. The middle parts of the two groups of anti-collision nets 22 protrude toward each other. At this time, the channel formed by the two groups of anti-collision nets 22 is a structure with large ends and small middle. The wind knife 10 is located in a recessed position on the outside of the anti-collision net 22. This arrangement reduces its volume, which is beneficial to reducing the space occupied by the wind knife assembly.
[0037] In some embodiments, the anti-collision net 22 includes two mounting rods 221 and multiple anti-collision wires 222. The two mounting rods 221 are perpendicular to the fixing frame 211, and one end of the two mounting rods 221 is connected to one side of the fixing frame 211. For example, the upper ends of the two mounting rods 221 of one anti-collision net 22 are respectively fixed on the two extending ends on the left side of the I-shaped plate structure, and the upper ends of the two mounting rods 221 of the other anti-collision net 22 are respectively fixed on the two extending ends on the right side of the I-shaped plate structure.

Specifically, mounting holes are provided on the sides of the two mounting rods 221 that are opposite to each other, and hooks are provided at the ends of the anti-collision wires 222. The hooks are used to hook on the mounting holes. When the anti-collision wires 222 need to be removed, the two ends of the anti-collision wires 222 can be pulled outward. It should be noted that the number of anti-collision wires 222 can be selected according to actual needs, and this embodiment does not make specific limitations on this.
[0038] In some embodiments, the ends of the two mounting rods 221 away from the fixing frame 211 are connected by a support rod. The support rod can improve the load-bearing stability of the mounting rod 221. The support rod can be connected to the mounting rod 221 by welding, screw connection or other methods, wherein the bending angle of the support rod is the same as the bending angle of the anti-collision wire 222.
[0039] The utility model also provides a wind knife device, including a fan, and also including the wind knife assembly provided in any of the above embodiments, the fan is connected to the wind knife assembly, and the fan is used to supply air to the wind knife assembly.
