Description

Technical Field

[0001] The invention belongs to the technical field of clothing and bag processing equipment, and particularly relates to an automatic spring buckle threading machine. Background Art

[0002] Spring buckles are widely used in the production of outdoor clothing, such as jackets, and luggage. Currently, threading these buckles is mostly done manually, which is inefficient and labor-intensive.

[0003] To address the above-mentioned issues, industry experts have developed a spring buckle threading device, such as the patent document CN112222808A, which includes a base, a fixed mold, and a movable mold. The fixed mold is disposed on the base; the movable mold is movably disposed on the base and can move relative to the fixed mold to achieve mold opening and closing. When the fixed mold and the movable mold are in the closed state, a rope winding channel and a spring buckle accommodating cavity are formed. The rope winding channel has an inlet and an outlet, which are respectively connected to the spring buckle accommodating cavity at the spring buckle threading holes. When air is introduced into the inlet, the threading rope can be passed through one threading hole and out of the other threading hole under the action of the air source. This device can assist manual threading operations, improve work efficiency, and reduce labor intensity. However, some processes still require manual completion, such as manual wire feeding, which affects work efficiency.

[0004] In view of this, the inventor conducted in-depth research on the above-mentioned defects in the prior art, which led to the present case. Summary of the Invention

When the two are connected, the elastic wire is passed through a threading hole of the spring buckle via the wire feeding mechanism, and enters the winding channel through the entrance of the winding channel. At the same time, the elastic wire can be conveyed by the wire feeding mechanism and can be passed through the exit and the other threading hole of the spring buckle in turn, thereby realizing the threading operation.

[0027] The present invention will be further described below with reference to 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.

[0028] The "wire feeding side" of the present invention refers to "the side of the wire feeding mechanism away from the winding channel".

[0029] 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.

[0030] The frame 1 is provided with a winding channel 4 and a spring buckle accommodating cavity 5. 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 extends toward a threading hole of the spring buckle 20, and the exit section 43 extends 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 exit are respectively connected with the spring buckle accommodating cavity 5 at the threading hole of the spring buckle 20.

[0031] The wire feeding mechanism 2 includes several wire feeding roller assemblies 21, a driver 22, and a synchronous belt 23. The driver 22 serves as the power device for the wire feeding roller assemblies 21 and is typically a motor. The synchronous belt 23 cooperates with each wire feeding roller assembly 21 to achieve power transmission between the different wire feeding roller assemblies 21. Each wire feeding roller assembly 21 includes two rollers, and the elastic wire 10 is sandwiched between the two rollers. The two rollers provide sufficient squeezing force and wire feeding friction to the elastic wire 10, so that the elastic wire 10 is fed along a threading hole of the spring buckle 20. Preferably, at least the surface of the roller that contacts the elastic wire 10 is made of ceramic or silicone to reduce wear on the elastic wire 10.

[0032] The wire transmission mechanism 3 includes a plurality of wire transmission pulleys 31, a driver 22, and a synchronous belt 23. The wire transmission pulleys 31 are evenly distributed along the outer edge of the winding channel 4. The driver 22 serves as the power device for the wire transmission pulleys 31. The driver 22 is conventionally a motor. The synchronous belt 23 cooperates with each wire transmission pulley 31 to achieve power transmission between different wire transmission pulleys 31. Each wire transmission pulley 31 includes two oppositely arranged wire transmission pulleys, which are distributed on both sides of the winding channel 4 and are used to clamp the elastic wire 10 and thus transport the elastic wire 10.

[0033] 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 holes 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.

[0034] Compared with the existing technology that requires manual wire feeding, the button threading machine of the present invention can realize automatic wire feeding operation, which to a certain extent reduces the labor intensity of manual labor, improves work efficiency, and reduces labor cost investment.

[0035] 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.

[0036] 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 slides in cooperation 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, and 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. 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.

[0037] 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.

[0038] In this embodiment, the buckle threading machine also includes a hot cutting machine 8, which is arranged between the spring buckle accommodating cavity 5 and the wire feeding mechanism 2. The hot cutting machine 8 has a heating source to heat the blade, so that the blade of the hot cutting machine 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.

[0039] 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 feed side of the wire feeding mechanism 2 .

[0040] The specific working process of the spring buckle 20 buckle threading machine of the present invention is as follows:

[0041] First, the spring buckle 20 to be threaded is placed in the spring buckle accommodating chamber 5, and the threading hole of the spring buckle 20 is opened; 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 wire feeding wheel and clamps 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 wire feeding wheel and releases the elastic wire 10. 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 operation of the spring buckle 20 can be completed by this cycle.

[0042] It should be understood that the above are only preferred embodiments 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.
