Description

Technical Field

[0001] This utility model relates to the field of button-attaching equipment, and in particular to a button-attaching device on an automatic button-attaching machine and an automatic button-attaching machine with the punching device. Background Art

[0002] A button-attaching machine is a device that attaches metal buttons or eyelets to clothing or fabric. Conventional automated button-attaching machines generally involve two processes: punching and fastening. Chinese patent document CN219229131U discloses an automatic button-attaching machine, including a frame with a button-picking platform, a punching mechanism, a first feeding pusher, a second feeding pusher, and a drive mechanism. The punching mechanism includes a punching die, a button-pressing die, a punching head, and a button-pressing head. The punching head and punching die are arranged vertically opposite each other, as are the button-pressing head and button-pressing die. In this patent, the punching die and button-pressing die are arranged side-by-side and linked in a forward-backward sliding direction. Therefore, after the punching head and punching die complete punching at a designated station, the button-pressing die with the button and the punching die move synchronously under the push of a cylinder until the button-pressing die reaches the designated station for buttoning. During this process, the sudden lateral movement of the lower clip within the pressure control mold can easily lead to positional displacement or the clip jumping out of the mold, resulting in defective products or clipping failure. Secondly, the punching process generates a large amount of fabric debris. This debris accumulates in the gaps at or near the designated workstation, easily causing blockages in machine parts and accelerating machine wear. Summary of the Invention

[0032] like Figure 1-8 As shown, a stamping device for an automatic button-fastening machine includes a punching head module, a button-pressing head module, a punching module 1, a button-pressing module 2, and a feeding module 3. The punching head module includes a punching head 100 and a drive device for pushing the punching head to move back and forth and up and down. The button-pressing head module includes a button-pressing head 101 and a drive device for pushing the button-pressing head 101 to move back and forth and up and down. The button-pressing head 101 also has the function of picking up the upper or lower button. The punching head module and the button-pressing head module are existing technologies, and their specific structures and working principles will not be described in detail here.

[0033] The punching module 1 includes a punching table 10 and a punching drive device 11 connected thereto. The punching drive device 11 enables the punching table 10 to move between a working position and a non-working position. The working position refers to the position of the punching table 10 when the punching head 101 presses down and cooperates with the punching table 10 to drill a hole. The non-working position, as the name suggests, is the position outside the working position area. The punching table 10 is provided with a working hole 12. When the punching head 100 presses down and inserts into the working hole 12, it punctures the fabric located in the working hole 12, so that the fabric forms a hole that can be fastened with a metal button or eyelet.

[0034] The feeding module 3 includes a base plate 31, a push plate 32, and a pusher 33; one end of the base plate 31 is connected to the punching table 10 and is located below the working hole 12; the base plate 31 has a second feeding hole 310 directly opposite the working hole 12; the push plate 32 is located above the base plate 31 and is pushed by the pusher 33 to slide along the base plate 31.

[0035] The snap-fit ​​module 2 is located in the working position and includes a snap-fit ​​platform 20 and a snap-fit ​​drive device 21 connected thereto; the snap-fit ​​drive device 21 can move the snap-fit ​​platform 20 up and down; when the punching platform 10 is located in the working position, the snap-fit ​​platform 20 is housed under the base plate 31.

[0036] To facilitate understanding of the working principle of this embodiment, this embodiment discloses an installation method for the stamping device, including a first fixed base 41, a second fixed base 42, and a third fixed base 43. As shown in the accompanying drawings, the push plate 32 is mounted on the second fixed base 42 via a push device 33. One end of the base plate 31 is connected to the punching table 10, and the other end extends below the push plate 32. The pressing table 20 is fitted onto the first fixed base 41 and slides up and down along the first fixed base 41. The punching table 10 is provided with a first guide groove 13. The first fixed base 41 is provided with a first slider 410 that slides with it. The first guide groove 13 is used to guide the punching table 10 between the working position and the non-working position. The third fixed base 43 is used to install the pressing table drive device 21 and is connected to the first fixed base 41.

[0037] In this embodiment, the snap-on head 101 can pick up the upper snap, while the lower snap is fed in sequence by the lower snap feeding device and pushed by the pusher plate 32 into the second feeding hole 310 of the falling base plate 31. The pusher device 33 is responsible for driving the pusher plate 32 to reciprocate. The pusher device, drive device, etc. in this embodiment can be a cylinder, a motor, or other automatic drive method. Since the snap-on machine's process is punching first and snapping second, when the punching table 10 is in the working position, the working hole 12, the second feeding hole 310, and the snap-on table 20 are kept in the same vertical direction, so that the lower snap can fall onto the snap-on table 20 through the second feeding hole 310. When the punching table 10 moves to the non-working position after punching, the snap-on table 20 is pushed upward to cooperate with the snap-on head 101 to snap the snap. Compared to existing technologies, the snap-fitting table 20 in this embodiment does not need to move laterally after obtaining the snap-fit; it only needs to rise vertically. This avoids the situation where the snap-fitting table shifts position due to inertia or falls during lateral displacement, thus improving the yield rate of snap-fitting.

[0038] Furthermore, in this embodiment, a work cover 103 is provided at the front end of the stamping device to cover components such as the punching table, which is both aesthetically pleasing and protective of the punching table 10. The fabric to be processed is laid on the surface of the work cover 103 for punching and pressing. The work cover is prior art and will not be described in detail here.

[0039] Furthermore, the push plate 32 is provided with a first feeding hole 320; when the buckle is fed in sequence by the buckle feeding device, it falls freely into the first feeding hole 320; the first feeding hole 320 is supported by a base plate 31, which can transport the buckle; when the first feeding hole 320 moves to be directly opposite the second feeding hole 310, the buckle falls freely from the second feeding hole 310 onto the pressing table 20. The second feeding hole 320 is provided with a notch to facilitate the buckle falling.

[0040] Furthermore, the pressing table 20 is provided with pressing holes 200; when the pressing table 20 is housed below the base plate 31, the pressing holes 300, the second feeding hole 310 and the working hole 12 are located on the same axis, which facilitates the positioning and processing of the pressing head 101.

[0041] Furthermore, the snap-on driving device 21 includes a snap-on cylinder 210; the output end of the snap-on cylinder 210 has an inclined surface 211; the bottom of the snap-on platform 20 has a guide inclined surface 201 adapted to the inclined surface 211; the inclined surface 211 of the snap-on cylinder moves back and forth along the guide inclined surface 201 to realize the lifting and lowering of the snap-on platform 20. Furthermore, the inclined surface 211 has a second guide groove 212; the bottom of the snap-on platform 20 has a second slider 202 that cooperates with it; the second guide groove 212 is used to guide the lifting and lowering of the snap-on platform 20.

[0042] Furthermore, the stamping device in this embodiment also has the function of collecting and removing debris left after punching. Specifically, the punching table 10 has a material drain trough 15 formed below the working hole 12. Fabric debris after punching will fall from the working hole 12 into the material drain trough 15.

[0043] Furthermore, it also includes a blowing device, such as a vacuum pump or an air pump; the blowing device is connected to the material leakage trough 15; the blowing device is used to remove debris from the material leakage trough 15 by blowing or sucking air. In this embodiment, the debris is blown away by blowing. More specifically, the punching platform 10 has an air hole 14 on one side for installing the blowing device; the air hole 14 is connected to the material leakage trough 15; the punching platform 10 has a discharge port 16 on the other side; the discharge port 16 is connected to the material leakage trough 15. When the blowing device is activated, gas enters the material leakage trough 15 from the air hole 14, blowing the debris out through the discharge port 16.

[0044] The specific steps of this embodiment are as follows: The punching table 10 is initially located in the working position, the snap-fit ​​table 20 is housed below the base plate 31 and already holds a lower snap-fit, while the punching head 101 also holds an upper snap-fit. The punching head 100 first presses down, cooperating with the punching table 10 to complete the punching process; after punching, the punching table 10 carries the base plate 31 and moves forward a short distance along the direction of the push plate 32; the punching head 100 moves in the opposite direction simultaneously, leaving the working position for the snap-fit ​​module 2 and the snap-fit ​​head module. The snap-fit ​​head module, which has picked up the upper snap-fit, moves to the working position, and the snap-fit ​​table 20, without interference from the base plate 31 and the punching table 10, also rises upwards to cooperate with the snap-fit ​​head 101 to snap-fit. After the snapping is completed, the snapping table 20 descends and resets, and the snapping head 101 returns to pick up the next upper snap; simultaneously, the punching table 10 moves backward and resets, and the punching head 100 resets forward to perform the next punching. At the same time, the pushing device 3 also pushes a new lower snap to the second material leakage hole 310, and the cycle repeats. The snapping device in this embodiment has almost no downtime, and the feeding, punching, and snapping processes are synchronized, which greatly improves efficiency compared to existing designs.

[0045] like Figure 1 As shown in the figure, this embodiment also discloses an automatic buttoning machine that uses the above-mentioned buttoning device.

[0046] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model.
