Detailed implementation manners

[0046] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below in conjunction with the implementation manners and the accompanying drawings. Herein, the illustrative implementation manners of the present application and their descriptions are used to explain the present application, but do not limit the present application.

[0047] Refer to Figures 1 to 7 As Figure 1 shown, this embodiment provides a bead feeding mechanism for a bead embroidery device of an embroidery machine, including: a support 1, a feeding device, a hose 6, a locking device 4 and a time-sharing clamping mechanism 5. The feeding device is installed on the support 1. The feeding device includes a vibrating bowl 2 and a blanking cylinder 21. The vibrating bowl 2 is arranged on the support 1. The blanking cylinder 21 is connected to the bottom of the vibrating bowl 2. The vibrating bowl 2 is a common structure in the prior art that can realize vibrating blanking. The bottom of the blanking cylinder 21 is connected with a hose 6. The embroidery beads 3 are placed in the feeding device. Through the vibration of the vibrating bowl 2, the embroidery beads 3 can fall into the hose 6 through the blanking cylinder 21, and then the feeding of the embroidery beads 3 is realized. There is a bead stringing hole in the middle of the embroidery beads 3 to string a plurality of embroidery beads 3 on a line, which is convenient for subsequent embroidery bead operations; the hose 6 is connected below the feeding device, and the hose 6 can convey the embroidery beads 3 downward; the locking device 4 is arranged on the support 1. The locking device 4 includes a limiting rod 47 that can horizontally expand and contract. By extending the limiting rod 47, the limitation of the embroidery beads 3 can be realized. By retracting the limiting rod 47, the embroidery beads 3 can pass through (i.e., bead passing); the time-sharing clamping mechanism 5 is arranged in the support 1 and is located below the locking device 4. The time-sharing clamping mechanism 5 can clamp the hose 6 to limit the embroidery beads 3 accommodated in the hose 6. The locking device 4 cooperates with a pair of time-sharing clamping mechanisms 5 to realize the quantitative feeding of the embroidery beads 3, and further realize the accurate feeding of the embroidery beads 3 to the next process.

[0048] As Figure 2As shown, the locking device 4 further includes: a first cylinder 41, a wedge block 43, a first compression spring 46, and a pressure wheel 44. The first cylinder 41 is installed on the bracket 1 through a fixed bracket 411. A piston rod 42 is provided at the lower end of the first cylinder 41. To facilitate the installation and operation of the piston rod 42, a first through hole 11 for allowing the piston rod 42 to move up and down is provided on the bracket 1. The wedge block 43 is connected to the lower end of the piston rod 42. By driving the piston rod 42 to move vertically by the first cylinder 41, the wedge block 43 can move vertically synchronously. The pressure wheel 44 is installed at the left end of the limit rod 47, and the pressure wheel 44 abuts against the wedge block 43. The first compression spring 46 is sleeved on the limit rod 47. When the first cylinder 41 drives the wedge block 43 to move downward, the wedge block 43 can drive the limit rod 47 to move horizontally to the right, so that the right end of the limit rod 47 moves into the hose 6, thereby preventing the embroidery beads 3 from continuing to fall. When the limit rod 47 moves, the first compression spring 46 is compressed. When the first cylinder 41 moves up and resets, the pressing action of the wedge block 43 on the pressure wheel 44 disappears. Then the first compression spring 46 drives the limit rod 47 to move left and reset.

[0049] Preferably, a limit plate 48 is fixedly arranged inside the bracket 1. The limit rod 47 is slidably inserted through the limit plate 48. The limit plate 48 can enable the limit rod 47 to move smoothly in the horizontal direction. A retaining ring 45 is installed on the limit rod 47. The retaining ring 45 is located on the left side of the limit plate 48. The first compression spring 46 abuts between the retaining ring 45 and the limit plate 48.

[0050] As Figure 3 , Figure 5 As shown, the time-sharing clamping mechanism 5 includes: a base 51, a second cylinder 52, a driving block 53, a second compression spring 58, and a pair of clamping components. The base 51 is installed inside the bracket 1. The second cylinder 52 is installed on the base 51. The driving block 53 is connected to the lower end of the second cylinder 52. For convenient installation, a second through hole 511 for the second cylinder 52 to pass through is provided on the base 51. The second compression spring 58 is connected between a pair of clamping components. A pair of clamping components are symmetrically connected inside the base 51. When the second cylinder 52 drives the driving block 53 to move downward, a pair of clamping components can clamp the hose 6, thereby preventing the embroidery beads 3 from continuing to fall downward.

[0051] Among them, a V-shaped groove 531 is provided inside the driving block 53. A pair of moving arms 55 of a pair of clamping components are slidably matched with the two side surfaces of the V-shaped groove 531.

[0052] As Figure 5 As shown, the clamping component includes: a moving arm 55, a connecting plate 56, and a clamping block 57. The moving arm 55 is slidably matched with the driving block 53. The connecting plate 56 is connected to the moving arm 55. The clamping block 57 is connected to the connecting plate 56. The clamping block 57 can abut against the hose 6. The second compression spring 58 is connected between a pair of moving arms 55.

[0053] Among them, the moving arm 55 includes a guiding portion 551 and a resisting portion 552 that are integrally connected. The guiding portion 551 is slidably connected to the base 51, and the resisting portion 552 has an outer inclined surface 553, and the outer inclined surface 553 is slidably engaged with a corresponding inner inclined surface 532 on the V-shaped groove 531.

[0054] As Figure 6 shown, side holes 554 are formed on one side of the two guiding portions 551 that are close to each other, and the second compression spring 58 is connected between a pair of side holes 554.

[0055] As Figure 7 shown, the clamping block 57 is provided with an avoidance groove 572 in a "V" shape to accommodate the hose 6. The avoidance groove 572 is provided with protruding portions 571 at intervals, and the protruding portions 571 abut against the outer wall of the hose 6, which can prevent slipping when clamping the hose 6, thereby improving the clamping effect on the hose 6.

[0056] As Figure 4 shown, a sunk groove 512 is further formed in the base 51. The sunk groove 512 is connected through below the second through hole 511. The driving block 53 is accommodated in the sunk groove 512, and side sliding grooves 513 are formed on both sides of the sunk groove 512. Sliders 54 are provided on both sides of the driving block 53, and the sliders 54 are slidably connected to the corresponding side sliding grooves 513. A guiding hole 514 is vertically formed at the bottom of the sunk groove 512, and a pair of moving arms 55 can slide relative to each other in the guiding hole 514. A pair of third through holes 515 are further formed below the guiding hole 514, and the third through holes 515 are used to accommodate the corresponding connecting plates 56 to move therein.

[0057] In the embodiment of the present application, when the second cylinder 52 is started, it can drive the driving block 53 to move downward. The downward movement of the driving block 53 will squeeze a pair of moving arms 55, so that a pair of moving arms 55 approach each other. Then a pair of connecting plates 56 drive a pair of clamping blocks 57 to approach each other, and finally the hose 6 is clamped.

[0058] Working principle: In the initial state, the locking device 4 is in the extended state, and the time-sharing clamping mechanism 5 is in the state of clamping the hose 6 to prevent the embroidery beads 3 from directly moving downward in the hose 6. During operation, the vibrating disk 2 vibrates, and the embroidery beads 3 in the vibrating disk 2 fall one by one to the locking device 4. The limit rod 47 moves rightward and extends to block the embroidery bead 3. When an embroidery bead 3 is needed below the hose 6, the limit rod 47 quickly retracts, allowing an embroidery bead 3 to pass through. The embroidery bead 3 moves to the time-sharing clamping mechanism 5. Since the time-sharing clamping mechanism 5 clamps the hose 6 at this time, the embroidery bead 3 cannot continue to move downward and stays at the time-sharing clamping mechanism 5. When an embroidery bead 3 is needed in the next process, the time-sharing clamping mechanism 5 releases the clamping of the hose 6, quickly clamps the hose 6 after the embroidery bead 3 falls, and then the limit rod 47 quickly retracts and extends, allowing an embroidery bead 3 to fall to the time-sharing clamping mechanism 5 and stay, waiting to fall. Repeating the above process subsequently can achieve the quantitative and precise feeding of the embroidery beads 3.

[0059] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the embodiments of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
