Description

Technical Field

[0001] The utility model relates to a bead supplying device. Background Art

[0020] See also Figure 1-5 This embodiment includes a bead supply device, including a feeding cup 1 arranged above the bead supply mechanism barrel 5, the bottom of the feeding cup 1 is provided with a discharge port 11 for feeding to the barrel 5, and one side of the feeding cup 1 is provided with a toggle groove 12 at the discharge port 11, and the feeding cup 1 is provided with a toggle rod 13 inserted into the discharge port 11 on the side corresponding to the toggle groove 12, and the toggle rod 13 is provided with a second driving structure for driving the toggle rod 13 to move in the toggle groove 12.

[0021] The second drive structure can be independently configured as needed, and a corresponding driver can be provided. For example, an electromagnet can be provided to drive the toggle lever 13, causing the toggle lever 13 to move within the toggle slot 12; the toggle lever 13 can be provided on the motor shaft of the drive motor, and the motor shaft can be used to drive the toggle lever 13 to swing; an intermediate actuator member connected to the electromagnet and the drive motor can be provided to connect the toggle lever 13 to move within the toggle slot 12. The second drive structure can be fully implemented using existing technical conditions.

[0022] Or as preferred in this embodiment, the first driver of the existing feeding cup plug can be used for driving.

[0023] To facilitate material discharge, the bottom of the feeding cup 1 is provided with a tapered guide surface 10 that guides the material toward the lower feeding port 11, and a portion of the toggle groove 12 is disposed at the tapered guide surface 10. Furthermore, the feeding port 11 of the feeding cup 1 is provided with a feeding tube 14 that can be inserted into the barrel 5, and a portion of the toggle groove 12 is disposed at the feeding tube 14, so that the toggle lever 13 can move between the upper and lower positions of the feeding port 11, facilitating the driving and toggling of the toggle lever 13, thereby ensuring that the beads can smoothly pass through the feeding port 11 from the tapered guide surface 10 and then smoothly fall into the barrel 5 from the feeding tube 14.

[0024] In order to facilitate driving and smoothly moving the beads at the discharge port 11, the length direction of the moving groove 12 is set up and down.

[0025] A plug 4 is provided at the bottom of the feed opening 11 of the feeding cup 1, which intermittently opens the feed opening 11 as the barrel 5 rotates. The plug 4 is equipped with a first actuator, which drives the plug 4. The first actuator constitutes the power source of the second drive structure. The first actuator intermittently opens and closes the barrel 5 as it rotates, intermittently controlling the opening of the plug 4 to achieve a stable drop of beads from the feeding cup 1.

[0026] For details, please refer to the accompanying drawings. The first driver includes a transmission assembly 2 mounted on the mounting bracket 7, a drive column 3 mounted on the cover plate 51 of the barrel 5, and cooperating with the transmission assembly 2 to drive the plunger 4. The discharge tube 14 may also be mounted on the cover plate 51. The toggle lever 13 is connected to the drive column 3 or the transmission assembly, and the drive column 3 or the transmission assembly constitutes the second drive structure of the toggle lever 13. As a preferred embodiment, the toggle lever 13 can be connected to the drive column 3, and the drive column 3 constitutes the second drive structure of the toggle lever 13. To facilitate the installation of the toggle lever 13, an extension portion can be provided on the drive column 3 above the cover plate 51, and the toggle lever 13 can be mounted on the extension portion.

[0027] The mounting frame 7 includes a mounting frame for mounting the transmission assembly and the barrel 5, and a frame structure of a corresponding shape is set according to the installation requirements. For example, a base 71 for mounting the rotating barrel 5 can be set, and a stand 71 connected to the base 71 can be installed on which the transmission assembly 2 is mounted.

[0028] The transmission assembly 2 includes a transmission rod 21 mounted on a mounting frame 7, a transmission arm 22 that drives the drive column 3, a cam 6 that drives the transmission rod 21, and a driven pulley 61 coaxially connected to the cam 6. The transmission rod 21 is rotatably mounted on the mounting frame 7, with one end of the transmission rod 21 mating with the cam 6 and the other end mating with the transmission arm 22. The transmission arm 22 is rotatably mounted on the mounting frame 7, and the mating between the ends of the transmission rod 21 and the transmission arm 22 drives the transmission arm 22. The barrel 5 is provided with a transmission wheel assembly 8 that drives the barrel 5 in rotation. The driven pulley 61 cooperates with a corresponding wheel in the transmission wheel assembly 8 to transmit power. The transmission wheel assembly 8 generally includes a driving pulley connected to a power shaft, a synchronous belt, and a driven pulley. A drive gear 62 is coaxial with the driven pulley. The driving gear cooperates with the driven pulley 61 (the driven gear) to drive the cam 6 in rotation. The drive gear 62 also simultaneously drives the barrel 5 in rotation via the barrel transmission gear.

[0029] The corresponding end of the transmission rod 21 is movably connected to a reciprocating rod 23 that cooperates with the cam 6, and the other end of the transmission rod 21 that cooperates with the transmission arm 22 is movably connected to the transmission arm 22; or a driving inclined surface 24 or a curved surface is provided between the other end of the transmission rod 21 that cooperates with the transmission arm 22 and the transmission arm 22.

[0030] In this embodiment, as a preference, in order to prevent the driving rod 31 and the driving column 3 from working independently without interfering with each other, the transmission arm 22 is connected with a driving rod 31 that can drive the driving column 3 to move, and the toggle rod 13 is connected to the driving rod 31, and the driving rod 31 constitutes a second driving structure of the toggle rod 13; the driving column 3 and / or the driving rod 31 may be respectively provided with a second return spring 32.

[0031] The material plug 4 is provided with a first return spring. The transmission arm 22 is provided with a third return spring 25 .

[0032] During use, the cam 6 cooperates with the reciprocating rod 23 provided on the stand 71 to drive the transmission rod 21 connected to the stand 71 to swing back and forth. The other corresponding end of the reciprocating transmission rod 21, i.e. the upper end, drives the transmission arm 22 to move upward through the driving inclined surface 24 or the curved surface. The upward-moving transmission arm 22 drives the toggle rod 13 to move upward in the toggle groove 12 through the driving rod 31. The driving column 3 resets upward under the action of the second reset spring 32, disengages from the pushing plug 4, and the plug 4 can open the outlet of the discharge pipe 14, so that the beads fall from the feeding cup 1 into the barrel 5 to realize feeding.

[0033] When the reciprocating transmission rod 21 disengages from the transmission arm 22, the transmission arm 22, under the action of the third return spring 25, drives the drive rod 31 downward to reset, simultaneously driving the toggle rod 13 downward within the toggle slot 12. The upward and / or downward movement of the toggle rod 13 enables the beads to be toggled at the discharge port 11, preventing bead blockage. The downward movement of the drive column 3 pushes the material plug 4, causing it to seal the outlet of the discharge tube 14, preventing excessive beads from falling into the barrel 5 and achieving a controlled drop of beads.
