Description

Technical Field

[0001] This utility model relates to the field of garment processing equipment, specifically a bead-punching mechanism for a bead-pinning machine. Background Technology

[0002] In existing technologies, beading machines typically place the bead-punching mechanism on the top surface of the fabric. During beading, the beads are conveyed to the top surface of the fabric, while the fasteners that mate with the beads are conveyed to the bottom surface. The punch of the bead-punching mechanism picks up the beads and moves downward, while the punch of the fastening mechanism pushes against the fasteners and moves upward, thereby securing the beads and fasteners to the fabric.

[0003] In the aforementioned prior art, the bead-attaching mechanism of a bead-attaching machine typically requires an additional bead mold for receiving and positioning the beads, ensuring that the beads are accurately held by the punch of the bead-attaching mechanism. Clearly, this additional bead mold design is structurally complex, and its compatibility with different types of beads is somewhat insufficient.

[0004] Therefore, it is necessary to propose a bead-receiving and positioning mechanism with a simpler structure. Utility Model Content

[0005] This utility model aims to meet the above-mentioned needs of the prior art and proposes a bead-punching mechanism for a bead-pinning machine, the technical solution of which is as follows.

[0006] A bead-punching mechanism for a bead-pinning machine includes a frame, and a feed rail, a rocker plate, and a punch assembly disposed on the frame.

[0007] The feed rail is inclined for downward output of beads at an angle;

[0008] The rocker arm is horizontally positioned below the discharge end of the feed rail to receive the beads output by the feed rail. The first end of the rocker arm is pivotally connected to the frame to enable it to flip up and down. The first end of the rocker arm is also provided with an elastic return device to drive the rocker arm that has been flipped down to return to its original position when no external force is applied. The second end of the rocker arm, relative to the first end, abuts against the lower edge of the discharge end of the feed rail when the rocker arm is horizontal.

[0009] The punch assembly is provided with a needle sleeve that forms a sliding pair with the frame in the vertical direction. An axially vertical guide rod is fixed to the upper end of the needle sleeve. The guide rod is used to connect to an external punching mechanism to drive the needle sleeve to move vertically up and down. An axially vertical needle bar is fixed to the lower end of the needle sleeve. The lower end face of the needle bar has a downwardly extending flange on one side.

[0010] When the needle sleeve is at the upper end of the lifting stroke, the lower end face of the needle bar is exactly connected to the upper edge of the discharge end of the feed rail, and the stop edge is exactly opposite to the discharge end to block the beads output by the feed rail to the rocker plate.

[0011] Furthermore, the needle rod is an axially hollow tube with an adsorption end formed on its lower end face; the needle sleeve has a cavity communicating with the needle rod, and the side wall of the needle sleeve is provided with an air nozzle that enters the cavity, the air nozzle being used to draw air to create a negative pressure in the cavity and inside the needle rod.

[0012] Compared with the prior art, the present invention has the following advantages: the beads conveyed to the rocker by the feed rail will be blocked by the stop edge at the lower end of the needle bar. Without setting an additional bead mold, the lower end face of the needle bar, the stop edge and the rocker can cooperate to limit the beads in multiple positions, which significantly simplifies the positioning method of the bead punching mechanism and has good compatibility with different beads.

[0013] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0026] Please see Figures 1 to 4 As shown, in one embodiment, the bead-punching mechanism for the bead-pinning machine includes a frame 1, and a feed rail 2, a rocker plate 3, and a punch assembly 4 disposed on the frame 1.

[0027] The feed rail 2 is inclined for outputting beads downwards at an angle;

[0028] The rocker plate 3 is horizontally positioned below the discharge end of the feed rail 2 to receive the beads output by the feed rail 2. The first end of the rocker plate 3 is pivotally connected to the frame 1 to enable it to flip up and down. The first end of the rocker plate 3 is also provided with an elastic return device 5, which is used to drive the rocker plate 3 that has been flipped down to flip up and reset when there is no external force. The second end of the rocker plate 3 relative to the first end abuts against the lower edge of the discharge end of the feed rail 2 when the rocker plate 3 is horizontal.

[0029] The punch assembly 4 is provided with a needle sleeve 41 that forms a sliding pair with the frame 1 in the vertical direction. The upper end of the needle sleeve 41 is fixed with an axially vertical guide rod 42, which is used to connect to an external punching mechanism to drive the needle sleeve 41 to move vertically up and down. The lower end of the needle sleeve 41 is fixed with an axially vertical needle rod 43, and the lower end face of the needle rod 43 has a downwardly extending flange 431 on one side edge.

[0030] When the needle sleeve 41 is at the upper end of the lifting stroke, the lower end face of the needle bar 43 is exactly connected to the upper edge of the discharge end of the feed rail 2, and the stop edge 431 is exactly opposite to the discharge end to block the beads output by the feed rail 2 to the rocker plate 3.

[0031] Combination Figure 3 As shown, the bead 9, fed onto the rocker plate 3 via the feed rail 2, is precisely blocked by the stop edge 431 at the lower end of the needle bar 43. Without the need for an additional bead mold, the lower end face of the needle bar 43, the stop edge 431, and the rocker plate 3 work together to limit the bead 9 in multiple positions, including vertically, horizontally, and at the front end, significantly simplifying the bead positioning method of the punching mechanism. Furthermore, when the shape and size of the beads differ, there is no need to change the bead mold as in existing technologies, thus providing good compatibility with different beads.

[0032] In a preferred embodiment, combined with Figure 2 , Figure 3 and Figure 4 As shown, the needle rod 43 is an axially hollow tube with an adsorption end 430 formed on its lower end face; the needle sleeve 41 has a cavity (not shown) communicating with the needle rod 43 inside, and an air nozzle 411 is provided on the side wall of the needle sleeve 41 to enter the cavity. The air nozzle 411 is used to draw air to generate negative pressure in the cavity and inside the needle rod 43.

[0033] exist Figure 3 In the shown working state, air is drawn in through the air nozzle 411, creating a negative pressure inside the cavity and the needle bar 43. The beads 9, conveyed by the feed rail 2 to the rocker plate 3, are attracted by this negative pressure at the adsorption end 430. Furthermore, in... Figure 4 In the working state shown, when the external stamping mechanism drives the needle sleeve 41 to descend vertically through the guide rod 42, the needle rod 43 and the bead 9 that is attracted by negative pressure at the adsorption end 430 will descend synchronously, causing the rocker plate 3 to be flipped down by force. The bead 9 that is attracted by negative pressure at the adsorption end 430 will not fall off, but will move downward with the needle rod 43.

[0034] In another preferred embodiment, such as Figure 5 As shown, the feed rail 2 includes an upper feed rail 21 and a lower feed rail 22 arranged in the same direction and inclined. The upper feed rail 21 and the lower feed rail 22 cooperate with each other to form a conveying channel. The upper feed rail 21 forms a blocking part 23 extending beyond the lower feed rail 22 at the discharge end along its inclined direction. The end of the blocking part 23 has a vertically opened clearance opening 24. When the needle sleeve 41 is located at the upper end of the lifting stroke, the suction end 430 just enters the clearance opening 24, and the stop edge 431 just fits with the outer edge of the end of the blocking part 23. Through the aforementioned arrangement, the upper side of the discharge end of the feed rail 2 is blocked by the blocking part 23. For the beads conveyed to the rocker plate 3 through the feed rail 2, the limiting area of ​​the top surface of the beads is actually increased, reducing the probability of the beads getting stuck at the output end of the feed rail 2.

[0035] Furthermore, in the aforementioned configuration, the top surface of the lower feed rail 22 forms a buffer section 221 that curves and transitions to a horizontal plane at the discharge end, and the bottom surface of the upper feed rail 21 forms a curved section 211 that curves and transitions to a horizontal plane at the discharge end. This buffers the beads that are fed onto the rocker 3 via the feed rail 2 at the end of the output path, reducing the probability of the beads rolling over due to excessive output speed to a certain extent. It further reduces the chance of the beads getting stuck at the output end of the feed rail 2, and also allows the beads to be fed onto the rocker 3 more smoothly via the feed rail 2.

[0036] In another preferred embodiment, such as Figure 1 and Figure 2As shown, the frame 1 is provided with a vertical slide rail 11, and the needle sleeve 41 is provided with a slider 412 that slides in cooperation with the vertical slide rail 11.

[0037] In another preferred embodiment, such as Figure 5 As shown, the frame 1 is provided with a horizontally arranged rotating shaft 12, and the second end of the rocker 3 is provided with a rotatable shaft bracket 31 that passes through the rotating shaft 12. The elastic recovery device 5 is a torsion spring that passes through the rotating shaft 12. One end of the torsion spring is connected to the frame 1, and the other end of the torsion spring is connected to the second end of the rocker 3.

[0038] In another preferred embodiment, such as Figure 1 As shown, the frame 1 is provided with a guide sleeve 13 coaxially sleeved on the guide rod 42. The guide sleeve 13 and the guide rod 42 are connected by a linear bearing 14, so that the guide rod 42 can maintain axial stability better when moving up and down.

[0039] In another preferred embodiment, such as Figure 2 As shown, the flange 431 forms an axially vertical arc surface on the side facing the axis of the needle bar 43.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
