Description

Technical Field

[0001] This utility model relates to the field of button attaching machine technology, and in particular to an automatic button feeding device for button attaching machines. Background Technology

[0002] The most common type of button sewing machine is for sewing disc-shaped two- or four-hole buttons. By replacing various specialized button sewing machine accessories, one machine can sew various types of buttons, including handle buttons, metal buttons, snap buttons, loop buttons, and capo buttons. When using a button sewing machine to sew buttons onto garments, an automatic button feeding device is required. Current automatic button feeding devices typically use a vibrating disc to vibrate at a certain frequency, causing the buttons to move along the inner wall of the vibrating disc. To prevent the buttons from moving side-by-side along the vibrating disc's inner wall, a screening plate is placed along the button's movement path. Since different buttons have different diameters, the position of the screening plate needs to be adjusted when feeding buttons of different sizes. Current automatic button feeding devices for button sewing machines, such as... Figure 1-2 As shown, the device includes a vibrating plate 10 and a screening assembly 20. The vibrating plate 10 has a spiral feeding track 101 inside. The screening assembly 20 includes a screening plate 201 and a mounting base 202. The screening plate 201 is located at the spiral feeding track 101 and smoothly transitions with the spiral feeding track 101. The screening plate 201 has a waist hole 2011. The mounting base 202 has a fixing hole. Bolts 203 are installed inside the fixing hole and the waist hole 2011. When it is necessary to adjust the position of the screening plate 201, the bolts 203 need to be loosened and the screening plate 201 needs to be moved manually to adjust its position. After the adjustment is completed, the position of the screening plate 201 is fixed by the bolts 203. The manual movement of the screening plate 201 to adjust its position cannot control the movement distance of the screening plate 201 well, and the adjustment accuracy is low. Therefore, the adjustment process is relatively cumbersome. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose an automatic button feeding device for a button-attaching machine. This solves the technical problem that in the existing automatic button feeding device for button-attaching machines, the position of the sieve plate is adjusted by manually moving the sieve plate, which cannot control the moving distance of the sieve plate well, has low adjustment accuracy, and therefore the adjustment process is relatively cumbersome.

[0004] To achieve the above technical objectives, the present invention provides an automatic button feeding device for a button-attaching machine, comprising a vibrating plate and a screening assembly. The vibrating plate is provided with a spiral feeding track, and the screening assembly includes a screening plate and a mounting base. The screening plate is located at the spiral feeding track and smoothly transitions with the spiral feeding track. The screening plate and the mounting base are connected by an elastic component, and a threaded rod is threadedly connected to the mounting base, which abuts against the screening plate.

[0005] Furthermore, the screening plate has serrations on the side closest to the inside of the vibrating plate, and a first folded edge on the side of the screening plate away from the inside of the vibrating plate, with one end of the threaded rod abutting against the first folded edge.

[0006] Furthermore, the mounting base has a second folded edge on the side away from the inside of the vibratory plate, and a first threaded hole is provided in the middle of the second folded edge, with the threaded rod threadedly connected inside the first threaded hole.

[0007] Furthermore, both ends of the first folded edge and both ends of the second folded edge are connected by an elastic component. The elastic component includes a connecting rod. Both ends of the first folded edge are provided with a first through hole, and both ends of the second folded edge are provided with a second through hole. Both ends of the connecting rod pass through the first through hole and the second through hole respectively and are provided with a limiting block. One of the limiting blocks is connected to the second folded edge by a spring.

[0008] Furthermore, the connecting rod and the limiting block are connected by threads.

[0009] Furthermore, the limiting block has a threaded groove inside, and the end of the connecting rod is threaded into the threaded groove.

[0010] Furthermore, the second flange is threaded with a threaded component for fixing the connecting rod inside the second through hole.

[0011] Furthermore, the second folded edge is provided with a second threaded hole that communicates with the first threaded hole, and the threaded part is threadedly connected inside the second threaded hole.

[0012] The beneficial effects of this utility model include: This utility model provides an automatic buckle feeding device for a button-attaching machine. Under the thrust of the elastic component, the rotating threaded rod can drive the screen plate to move and adjust the position of the screen plate. Compared with the existing automatic buckle feeding device for button-attaching machines that uses manual movement of the screen plate to adjust the position of the screen plate, this device can better control the movement distance of the screen plate, has high adjustment accuracy, and therefore the adjustment process is simple, which can improve the efficiency of adjusting the position of the screen plate.

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] This utility model embodiment provides a button feeding device for a button-attaching machine, such as... Figure 3-4 The device includes a vibrating plate 1 and a screening assembly 2. The vibrating plate 1 has a spiral feeding track 11 inside. The screening assembly 2 includes a screening plate 21 and a mounting base 22. The screening plate 21 is located at the spiral feeding track 11 and smoothly transitions with the spiral feeding track 11. The screening plate 21 and the mounting base 22 are connected by an elastic component 23. The mounting base 22 is fixedly installed on the vibrating plate 1. A threaded rod 24 is threadedly connected to the mounting base 22. The threaded rod 24 abuts against the screening plate 21. Under the thrust of the elastic component 23, the screening plate 21 can be driven to move horizontally by rotating the threaded rod 24, thereby adjusting the position of the screening plate 21. Compared with the existing buckle feeding device of the fastener machine, which uses manual movement of the screening plate 21 to adjust the position of the screening plate 21, this device can better control the movement distance of the screening plate 21, has high adjustment accuracy, and therefore simplifies the adjustment process and improves the efficiency of adjusting the position of the screening plate 21.

[0016] In this embodiment, the sieve plate 21 has serrations 211 on the side near the inside of the vibrating plate 1, and a first folded edge 212 on the side away from the inside of the vibrating plate 1. The first folded edge 212 is perpendicular to the sieve plate 21. The sieve plate 21 is located below the mounting base 22, and one end of the threaded rod 24 abuts against the first folded edge 212.

[0017] It should be noted that the mounting base 22 has a second folded edge 221 on the side away from the inside of the vibrating plate 1. The second folded edge 221 is perpendicular to the mounting base 22. The second folded edge 221 has a first threaded hole 2211 in the middle. The threaded rod 24 is threaded into the first threaded hole 2211.

[0018] In this embodiment, as Figure 5 As shown, both ends of the second folded edge 221 are connected to both ends of the first folded edge 212 via elastic components 23. The elastic components 23 include connecting rods 231. Both ends of the first folded edge 212 are provided with first through holes 2121, and both ends of the second folded edge 221 are provided with second through holes 2212. Both ends of the connecting rod 231 pass through the first through holes 2121 and the second through holes 2212 respectively and are provided with limiting blocks 232. One of the limiting blocks 232 is connected to the mounting base 22 via a spring 233. The elastic components 23 with the above structure not only have good elastic performance, but also allow the screening plate 21 to move stably. At the same time, the connecting rod 231 and the limiting block 232 are threadedly connected, which can facilitate disassembly and assembly.

[0019] It should be noted that the limiting block 232 has a threaded groove 2321 inside, and the end of the connecting rod 231 is threaded into the threaded groove 2321.

[0020] When the vibrating plate 1 is feeding material, the spring 233 may extend or retract due to the vibration of the vibrating plate 1, causing the connecting rod 231 to move, and thus causing the screening plate 21 to move. In order to avoid the above-mentioned problem, in this embodiment, the second folded edge 221 is threadedly connected with a threaded part 25 for fixing the connecting rod 231 inside the second through hole 2212. The threaded part 25 is either a thread or a screw, so as to prevent the connecting rod 231 from moving due to vibration when the vibrating plate 1 is feeding material, thereby preventing the screening plate 21 from moving.

[0021] It should be noted that, as Figure 6 As shown, the second folded edge 221 is provided with a second threaded hole 2213 that communicates with the first threaded hole 2211, and the threaded part 25 is threadedly connected to the inside of the second threaded hole 2213.

[0022] Specific principle: When adjusting the position of the screening plate 21, the threaded part 25 is loosened, and the threaded rod 24 is rotated. The threaded rod 24 can drive the screening plate 21 to move, thereby adjusting the position of the screening plate 21. After adjustment, the connecting rod 231 is fixed in the second through hole 2212 through the threaded part 24 to fix the position of the screening plate 21. Compared with the existing automatic buckle feeding device of the fastener machine, which uses manual movement of the screening plate 21 to adjust the position of the screening plate 21, this method can better control the movement distance of the screening plate 21, and has high adjustment accuracy. Therefore, the adjustment process is simple and can improve the efficiency of adjusting the position of the screening plate 21.

[0023] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
