[0021] The present invention is further described below in conjunction with the accompanying drawings and specific examples. Obviously, the specific examples described here are only used to explain the present invention, and are not used to limit the present invention.

[0022] The "wire-incoming side" of the present invention refers to "the side of the wire-feeding mechanism away from the wire-winding channel".

[0023] See also Figures 1 to 5 The present invention discloses an automatic spring buckle 20 threading machine, comprising: a frame 1, a wire feeding mechanism 2 and a wire conveying mechanism 3.

[0024] The frame 1 is provided with a winding channel 4 and a spring buckle accommodating cavity 5, and the winding channel 4 is composed of an entrance section 41, a semi-annular section 42 and an exit section 43 which are smoothly connected in sequence. The entrance section 41 is extended toward a threading hole of the spring buckle 20, and the exit section 43 is extended toward another threading hole of the spring buckle 20. The entrance section 41 is provided with an entrance at a threading hole close to the spring buckle 20, and the exit section 43 is provided with an exit at another threading hole close to the spring buckle 20. The entrance and the exit are respectively connected with the spring buckle accommodating cavity 5 at the threading hole of the spring buckle 20.

[0025] The wire feeding mechanism 2 includes a plurality of wire feeding roller groups 21, a driver 22 and a synchronous belt 23. The driver 22 is used as a power device for the wire feeding roller group 21. The driver 22 is generally a motor. The wire feeding roller groups 21 are matched with each other through the synchronous belt 23 to realize power transmission between different wire feeding roller groups 21. Each wire feeding roller group 21 includes two rollers, and the elastic wire 10 is sandwiched between the two rollers. The two rollers give the elastic wire 10 sufficient extrusion force and wire feeding friction force, so that the elastic wire 10 is transported along a threading hole of the spring buckle 20. Preferably, at least one side of the roller in contact with the elastic wire 10 is made of ceramic or silicone material to reduce the wear of the elastic wire 10.

[0026] The wire transmission mechanism 3 includes a plurality of wire transmission wheel groups 31, a driver 22 and a synchronous belt 23. The wire transmission wheel groups 31 are evenly distributed on the outer edge of the winding channel 4. The driver 22 is used as a power device for the wire transmission wheel groups 31. The driver 22 is generally a motor. The wire transmission wheel groups 31 are matched with each other through the synchronous belt 23 to realize power transmission between different wire transmission wheel groups 31. Each wire transmission wheel group 31 includes two wire transmission wheels arranged opposite to each other. The two wire transmission wheels are distributed on both sides of the winding channel 4, which are used to clamp the elastic wire 10 and then transport the elastic wire 10.

[0027] With the above design, during the specific operation of the buckle threading machine of the present invention, the spring buckle 20 to be threaded can be placed in the spring buckle accommodating chamber 5, and the threading hole of the spring buckle 20 can be opened to ensure that the entrance and exit of the winding channel 4 are respectively connected with the threading hole of the spring buckle 20. When the two are connected, the elastic wire 10 is passed through a threading hole of the spring buckle 20 via the wire feeding mechanism 2, and enters the winding channel 4 through the entrance of the winding channel 4. At the same time, the elastic wire 10 can be conveyed by each wire feeding wheel group 31 and can be passed through the exit and the other threading hole of the spring buckle 20 in turn, thereby realizing the threading operation.

[0028] Compared with the prior art which requires manual wire feeding, the buckle threading machine of the present invention can realize automatic wire feeding operation, which reduces the labor intensity of manual work to a certain extent, improves work efficiency, and reduces labor cost investment.

[0029] Preferably, a plurality of guard plates 9 are provided on the outer edge of the winding channel 4, and the guard plates 9 are arranged around the center of the semi-annular segment 42. The arrangement of the guard plates 9 makes it difficult for the elastic wire 10 to pop out of the winding channel 4 during the threading operation.

[0030] In this embodiment, the buckle threading machine also includes a clamping mechanism 7; a plurality of slide grooves 6 corresponding to the wire feeding wheel group 31 are provided on the outer edge of the winding channel 4 on the frame 1, and a wire feeding wheel of each wire feeding wheel group 31 is slidably matched with the corresponding slide groove 6, and the wire feeding wheel is defined as a slidable wire feeding wheel; the clamping mechanism 7 includes a plurality of movable wheel frames 71, a plurality of struts 72 and a screw 73 arranged corresponding to the slide groove 6, the movable wheel frame 71 is arranged on the slidable wire feeding wheel, the screw 73 is rotatably arranged on the frame 1, and the two ends of the strut 72 are respectively arranged on the movable wheel frame 71 and the screw 73, and by rotating the screw 73, the movable wheel frame 71 is driven to move up and down, and then the slidable wire feeding wheel is driven to slide along the corresponding slide groove 6, so that the slidable wire feeding wheel and the opposite side wire feeding wheel are close to or away from each other, thereby clamping or releasing the elastic line 10.

[0031] With the above design, when the two wire feeding wheels of each wire feeding wheel group 31 approach and clamp the elastic wire 10, the wire feeding wheels give the elastic wire 10 sufficient squeezing force and wire feeding friction force, so that the elastic wire 10 is transported in the winding channel 4 to realize the threading operation; after the threading is completed, when the two wire feeding wheels move away from and release the elastic wire 10, the threaded spring buckle 20 can be taken out.

[0032] In this embodiment, the buckle threading machine also includes a hot cutter 8, which is arranged between the spring buckle accommodating cavity 5 and the wire feeding mechanism 2. The hot cutter 8 has a heating source to heat the blade, so that the blade of the hot cutter 8 can melt the elastic wire 10, so that the elastic wire 10 has a cleaner cross-section at the cut, reducing burrs and damage.

[0033] In this embodiment, the button threading machine further includes an elastic wire support 30 , which is used to surround the elastic wire 10 and is arranged at the wire inlet side of the wire feeding mechanism 2 .

[0034] The specific working process of the spring buckle 20 buckle threading machine of the present invention is as follows: First, place the spring buckle 20 to be threaded in the spring buckle accommodating chamber 5, and open the threading hole of the spring buckle 20; then, the wire feeding mechanism 2 starts to feed the wire, and the wire feeding roller group 21 of the wire feeding mechanism 2 and the wire feeding wheel group 31 of the wire feeding mechanism 3 rotate synchronously; then, after the elastic wire 10 passes through a threading hole of the spring buckle 20, the support rod 72 of the clamping mechanism 7 drives the slidable wire feeding wheel to approach the opposite side wire feeding wheel and clamp the elastic wire 10, thereby conveying the elastic wire 10; finally, after the elastic wire 10 passes through the other threading hole of the spring buckle 20, the hot cutting machine 8 cuts off the elastic wire 10 and closes the threading hole of the spring buckle 20, the support rod 72 drives the slidable wire feeding wheel away from the opposite side wire feeding wheel and releases the elastic wire 10, and the threaded spring buckle 20 is taken away manually or by a robot. At this step, the threading operation of one spring buckle 20 has been completed, and the subsequent threading operations of the spring buckle 20 can be completed in this cycle.

[0035] It should be understood that the above are only preferred implementations of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
