[0002] Protective netting is a product used for protection and isolation. Regardless of the type of protective netting, its strength and quality are crucial factors. Among the factors affecting strength, besides the materials used, the method of fixing the netting's intersections is also important. In the mass production of existing protective netting, the netting ropes generally use... Figure 1 The methods shown are physical wrapping or using a knotting machine to fasten knots at the nodes for connection. Protective nets made using these two methods are convenient for mass production, but when opened for use, the net ropes bend at the connection nodes and are under stress and compression.

[0053] Example:

[0054] This embodiment provides a netting fastener machine for mass production. Figure 2 The net shown includes longitudinally extending warp threads and laterally extending weft threads, which are arranged in a cross shape and connected at the intersections by cross-shaped clips 10.

[0055] Please refer to Figures 3 to 5The netting fastener machine includes a frame 1, on which are sequentially arranged warp guide station 2, weft transfer station 3, node connection station 4, and winding station 5. The sequential arrangement refers to the process sequence, not a relative positional relationship; actual relative positions may overlap. The warp guide station 2 includes linearly spaced guide units 201. In this embodiment, there are twenty-four sets of guide units 201. Of course, in other embodiments, the number of guide units 201 can be adjusted according to actual conditions. The netting to be woven includes warp and weft threads. After the warp threads are led out from the guide units 201, they pass through the weft transfer station 3 and the node connection station 4, and are finally wound up to the winding station 5. The weft transfer station 3 is used to arrange the weft threads crosswise with the warp threads, and the node connection station 4 is used to connect the cross-shaped fasteners 10 at the intersections of the warp and weft threads. The weft transfer station 3 includes a clamping mechanism 301, which reciprocates through the passage of all guide units 201 along the arrangement direction of the guide units 201. After clamping the weft, the clamping mechanism 301 moves through all twenty-four warp threads, achieving a cross arrangement of warp and weft. The node connection station 4 includes a feeding device 401, a transfer device 402, and a stamping die 403. The feeding device 401 is used to feed the cross-shaped clips 10. The transfer device 402 reciprocates between the feeding device 401 and the stamping die 403 to transfer the cross-shaped clips 10 from the feeding device 401 to the stamping die 403. The stamping die 403 slides through the passage of all guide units 201 along the arrangement direction of the guide units 201. By sliding, the stamping die 403 can be aligned with any warp and weft node to install the cross-shaped clips 10 at the corresponding warp and weft node. After each node is connected, the stamping die 403 slides horizontally to the next node. Simultaneously, the transfer device 402 transports the next cross buckle 10 from the feeding device 401 to the stamping die 403 for connection to the next node. The netting continuously moves under the winding station 5 for continuous production. The netting buckle machine can fully automate the entire process of weaving, connecting, and winding, facilitating large-scale mass production.

[0056] Furthermore, based on Figure 6 and Figure 7As shown, the warp guide station 2 also includes a wire feeding component 202 mounted on the frame 1 and a rotating shaft 203 rotatably mounted on the frame 1. The rotating shaft 203 can be mounted on the frame 1 via bearings and bearing seats. The wire feeding component 202 has wire feeding holes 204 that correspond one-to-one with the guide units 201. In this embodiment, the number of wire feeding holes 204 is twenty-four. Each set of guide units 201 includes a first pulley 205 and a second pulley 206 whose axes are perpendicular to each other and whose edges are opposite. The first pulley 205 is rotatably mounted on the frame 1, and the second pulley 206 is sleeved and mounted on the rotating shaft 203. The twenty-four warp threads pass through the twenty-four wire feeding holes 204 respectively and then sequentially wind around the corresponding first pulley 205 and second pulley 206 to complete the feeding and arrangement of the warp threads.

[0057] based on Figure 7 and Figure 8 As shown, the system also includes a pulley bearing 207. The frame 1 has vertical shafts 208 corresponding to the first pulleys 205. A step 209 is provided at the end of the vertical shaft 208. The pulley bearing 207 is sleeved on the outside of the step 209, and the first pulley 205 is sleeved on the outside of the pulley bearing 207, achieving a rotatable connection between the first pulley 205 and the frame 1. A baffle 210 is bolted to the end of the vertical shaft 208. The inner ring of the pulley bearing 207 is clamped between the end of the step 209 and the baffle 210, achieving axial positioning of the pulley bearing 207 and the vertical shaft 208. The first pulley 205 has a groove 211. The pulley bearing 207 is sleeved in the groove 211. An annular retaining ring 212 is bolted to the opening of the groove 211, abutting against the end of the outer ring of the pulley bearing 207, achieving axial positioning between the pulley bearing 207 and the first pulley 205. The second pulley 206 has bushings 213 fitted on the rotating shaft 203 on both sides. The bushings 213 have set screws 214 screwed onto the rotating shaft 203 from the outer side wall to achieve axial positioning of the second pulley 206.

[0058] Furthermore, based on Figure 9As shown, the weft transfer station 3 also includes a clamping slide rail 302, an upper thread pulley 303, and a fixed pneumatic gripper 304, all of which are mounted on the frame 1. The clamping slide rail 302 is parallel to the arrangement direction of the guide unit 201, and the upper thread pulley 303 and the fixed pneumatic gripper 304 are located at both ends of the clamping slide rail 302. The clamping mechanism 301 includes a first mounting base 305 slidably disposed on the clamping slide rail 302 and a transfer pneumatic gripper 306 mounted on the first mounting base 305. The transfer pneumatic gripper 306 reciprocates between the upper thread pulley 303 and the fixed pneumatic gripper 304. In use, the weft yarn is fed through the upper pulley 303. The transfer gripper 306 clamps the end of the weft yarn at the upper pulley 303. The first mounting base 305 drives the transfer gripper 306 to slide along the clamping slide rail 302 to the fixed gripper 304. The fixed gripper 304 clamps the weft yarn, thus completing the operation of the weft yarn passing through the warp yarn. The sliding of the first mounting base 305 along the clamping slide rail 302 can be achieved by a transmission belt, ball screw, or push rod, which is a conventional setting and will not be described in detail.

[0059] Meanwhile, two sets of cutting devices 307 are provided between the upper pulley 303 and the fixed gripper 304, respectively. The two sets of cutting devices 307 are located close to the upper pulley 303 and the fixed gripper 304. The cutting devices 307 can be electrically controlled scissors, reciprocating blades, or devices that modify the gripping end of the gripper to a sharp shape to achieve the cutting function. After the weft thread passes through the warp thread and the node is connected by the cross clamp 10, the transfer gripper 306 returns to the space between the upper pulley 303 and the cutting device 307 near the upper pulley 303, and the transfer gripper 306 clamps the weft thread. At this time, the cutting device 307 near the fixed gripper 304 cuts off the end of the weft thread to remove the excess end, and the cutting device 307 near the upper pulley 303 cuts the weft thread to separate it from the weft thread to be fed later.

[0060] Furthermore, based on Figure 5 , Figure 10 , Figure 12 and Figure 13As shown, the node connection station 4 also includes a sliding frame 404 slidably mounted on the machine frame 1. The stamping die 403 includes a punch 405, a die 406, and a stamping cylinder 407. The punch 405 includes a support base 408 and a movable seat 409. The stamping cylinder 407 and the punch 405 are both mounted on the sliding frame 404. The die 406 is connected to the output end of the stamping cylinder 407. The stamping die 403 slides along the machine frame 1 with the sliding frame 404, aligning itself with each node in sequence. In use, the die 406 and the punch 405 are located on opposite sides of the node. The die 406 has a cross-shaped punch groove 410 with a smooth transition at the bottom wall on the side facing the punch 405. The support base 408 has a cross punch 411 matching the cross-shaped punch groove 410 on its side wall facing the cross-shaped punch groove 410. The movable seat 409 has a cross-shaped through hole 412. A cross punch 411 slides through a cross hole 412. A sliding rod 413 slides through a support base 408 on a movable seat 409. An elastic element 414 is held between the movable seat 409 and the support base 408. The elastic element 414 can be a spring sheet or a spring wound around the sliding rod 413. To ensure the stability of the die 406's movement, a guide rail 423 is also provided on the sliding frame 404, and the die 406 is slidably mounted on the guide rail 423.

[0061] When using it, firstly, based on Figure 12 As shown, the movable seat 409 is away from the support seat 408, and the cross punch 411 retracts into the inside of the cross through hole 412. The transfer device 402 reciprocates on the side of the loading device 401 and the cross through hole 412 away from the support seat 408 to transfer the cross latch 10 from the loading device 401 into the cross through hole 412, with the open end of the cross latch 10 facing the die cavity 406 (not shown in the figure). Subsequently, based on Figure 13 As shown, the die 406 extends to abut against the movable seat 409 under the action of the stamping cylinder 407, bringing the movable seat 409 closer to the support seat 408. The cross punch 411 drives the cross latch 10, warp and weft threads to extend into the cross punch groove 410. Because the bottom wall of the cross punch groove 410 has a smooth transition, the opening of the cross latch 10 deforms and wraps around the warp and weft threads after contacting the bottom wall of the cross punch groove 410. Finally, the die 406 returns to its original position under the action of the stamping cylinder 407, and the movable seat 409 returns to its original position under the action of the elastic element 414.

[0062] In this embodiment, the sliding frame 404 is U-shaped, and the punch 405 and the die 406 are located at the top two ends of the U-shaped sliding frame 404, respectively. The guide unit 201 is arranged to pass through the interior of the U-shaped sliding frame 404 to facilitate the placement of the warp thread between the punch 405 and the die 406.

[0063] Furthermore, based on Figure 5 and Figure 14As shown, the feeding device 401 is a vibratory feeder. The frame 1 is equipped with a feeding slide rail 415 parallel to the arrangement direction of the guide unit 201. The transfer device 402 includes a second mounting base 416 slidably disposed on the feeding slide rail 415 and an electromagnet 417 mounted on the second mounting base 416. The sliding of the second mounting base 416 along the feeding slide rail 415 can be achieved by a transmission belt, ball screw, or push rod, which is a conventional setting. The vibratory feeder, through vibration, can ensure that the cross latches 10 are aligned in the same direction during feeding. When the transfer device 402 moves to the vibratory feeder, the electromagnet 417 is energized, attracting the cross latches 10. When the electromagnet 417 moves to the cross through hole 412, the electromagnet 417 is de-energized, so that the cross latches 10 are lowered.

[0064] At the same time, based on Figures 10 to 12 As shown, the stamping die 403 also includes a rotary motor 418 mounted on a sliding frame 404, and a support base 408 connected to the output shaft of the rotary motor 418. Rotary shafts 424 are provided on both sides of the support base 408, and the rotary shafts 424 are mounted on the sliding frame 404 via bearings and bearing seats. The rotary motor 418 drives the punch 405 to rotate, causing the cross through hole 412 to alternately align with the cross punch slot 410 and the electromagnet 417. When the punch 405 rotates to... Figure 11 When positioned as shown, its cross-shaped through-hole 412 faces upwards. At this time, the electromagnet 417 moves with the cross-shaped latch 10 to directly above the cross-shaped through-hole 412. After the electromagnet 417 is de-energized, the cross-shaped latch 10 falls into the cross-shaped through-hole 412. Subsequently, the punch 405 rotates to... Figure 12 As shown, the cross-shaped through hole 412 is positioned facing the die 406, allowing for stamping connection.

[0065] Furthermore, based on Figure 15 As shown, the frame 1 is equipped with a stamped slide rail 419 parallel to the arrangement direction of the guide unit 201 and a rack 420 arranged parallel to the stamped slide rail 419. A gear 421 meshing with the rack 420 is rotatably mounted on the sliding frame 404, and a transfer motor 422 is mounted on the sliding frame 404 and driven by the gear 421. The transfer motor 422 drives the gear 421 to rotate, thereby moving the sliding frame 404 along the frame 1. To ensure stability during movement, the stamped slide rail 419, rack 420, and gear 421 are all provided in two sets.

[0066] Furthermore, based on Figure 3 and Figure 4 As shown, the winding station 5 includes a winding roller 501 and a drive roller. The drive roller includes a driving roller 502 and a driven roller 503 arranged side by side. The winding roller 501, driving roller 502, and driven roller 503 are all mounted on the frame 1. After the warp and weft threads are connected, they pass between the driving roller 502 and the driven roller 503, are led out by the driving roller 502, and finally wound around the winding roller 501.

[0067] In this embodiment, the winding station 5 also includes a transition roller 504 rotatably mounted on the frame 1. Both the transition roller 504 and the drive roller are located at the top of the frame 1, with the transition roller 504 spaced apart from the drive roller. The winding roller 501 is located at the bottom of the frame 1 and on the underside of the transition roller 504. The warp guide station 2, the weft transfer station 3, and the node connection station 4 are all located on the underside of the drive roller. The clamping mechanism 301 and the stamping die 403 are located between the winding roller 501 and the guide unit 201. At this time, the entire netting machine is in a U-shape. The netting first rises vertically for weaving and connection, moves horizontally a distance at the top, and then moves downwards and is wound up. This method facilitates monitoring personnel to observe the progress of each process and check the quality of the finished product.

[0068] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
