[0029] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0030] The up and down directions described in the present invention refer to Figure 1 The up and down directions in the present invention refer to the left and right directions. Figure 1 left and right direction in center.

[0031] like Figure 1-3As shown, the feeding mechanism of the tattoo needle assembly machine provided by the present invention is used to convey materials for assembling tattoo needles, and the feeding mechanism includes: a vibration plate 10, a feeding bin 20, a feeding trough 30, a vibration table 40 and a detection component 50, wherein the vibration plate 10 causes the materials in the vibration plate 10 to flow out in order by vibration, and the bottom wall 11 of the vibration plate 10 is parallel to the horizontal plane; the feeding bin 20 is located above the side of the vibration plate 10, and the feeding bin 20 is used to replenish materials into the vibration plate 10, and a bottom outlet 21 is provided at the bottom of the feeding bin 20. By providing the feeding bin 20, the amount of materials required for a shift (12 hours) or a day (24 hours) can be stored in the feeding bin 20 at one time; the conveying trough 30 is used to convey the materials in the feeding bin 20 to the vibration plate 10, and the left end of the conveying trough 30 is located directly below the bottom outlet 21, and there is a gap for the passage of materials between the bottom of the left end of the conveying trough 30 and the bottom outlet 21, and the conveying trough The right end of 30 is suspended above the vibration plate 10, the projection of the edge of the right end of the conveying trough 30 on the bottom wall 11 of the vibration plate 10 passes through the center of the bottom wall 11, and the left end of the conveying trough 30 is slightly higher than the right end of the conveying trough 30, so that the bottom of the conveying trough 30 forms an inclined surface inclined toward the vibration plate 10; the vibration table 40 is connected to the left end of the conveying trough 30. When the vibration table 40 is started, the conveying trough 30 follows the vibration and conveys the material flowing out of the bottom outlet 21 into the vibration plate 10; the detection component 50 is used to detect the amount of material in the vibration plate 10. The detection component 50 is electrically connected to the control circuit of the vibration table 40. When the detection component 50 detects that the amount of material in the vibration plate 10 is lower than the set value, the control circuit controls the vibration table 40 to start and vibrate the feed trough 30. When the detection component 50 detects that the amount of material in the vibration plate 10 reaches or exceeds the set value, the control circuit controls the vibration table 40 to stop and make the feed trough 30 stationary.

[0032] In order to prevent the detection component 50 from being disturbed by the materials dropped from the conveying trough 30 and the material path of the vibration plate 10 and to improve the accuracy of the detection result, in the present embodiment, the detection component 50 includes a bakelite board 51, a metal rod 52, and a contact. The bakelite board 51 is fixed on the top of the vibration plate 10, the upper end of the metal rod 52 is rotatably connected to the bakelite board 51, the lower end of the metal rod 52 extends into the vibration plate 10 and contacts with the materials, the contact is embedded in the bakelite board 51, the contact and the metal rod 52 are connected in series to the control circuit, specifically, the contact is connected to one end of the positive voltage or negative voltage of the control circuit, the metal rod 52 is connected to one end of the zero voltage of the control circuit, when the metal rod 52 is connected to the contact, the control circuit controls the vibration table 40 to start or stop, when the metal rod 52 is not connected to the contact, the voltage on the metal rod 52 is zero, and the static electricity on the material (especially plastic material) in contact with the metal rod 52 will be discharged by the metal rod 52, thereby achieving the technical effect of eliminating the static electricity of the material.

[0033] The amount of material in the vibration plate 10 will affect the efficiency of the vibration plate 10. The efficiency of the vibration plate 10 will be maximized only when it is stabilized at a certain value. However, this is obviously an ideal state. During actual use, it is impossible to dynamically stabilize the amount of material in the vibration plate 10 at a certain fixed value. Therefore, it becomes an inevitable choice to control the amount of material in the vibration plate 10 within a certain range.

[0034] In this embodiment, in order to control the amount of material in the vibration plate 10 within a certain range, there are two contacts, namely the first contact 53 and the second contact 54. The first contact 53 and the second contact 54 are arranged at intervals. When the metal rod 52 is connected to the first contact 53, the control circuit controls the vibration table 40 to start, and the feed trough 30 conveys the material to the vibration plate 10. As the material in the vibration plate 10 gradually increases, the material moves on the bottom wall 11 of the vibration plate 10, driving the metal rod 52 to rotate, so that the metal rod 52 is separated from the first contact 53. At this time, the feed trough 30 is still moving toward the vibration plate. The material is conveyed in the moving plate 10. When the metal rod 52 rotates to connect the second contact 54, the control circuit controls the vibration table 40 to stop, and the feed trough 30 stops conveying the material into the vibration plate 10. The material in the vibration plate 10 gradually decreases, and the material thrust on the metal rod 52 gradually decreases. When the material thrust cannot overcome the self-weight of the metal rod 52, the metal rod 52 rotates in the opposite direction under the action of its own weight to disengage from the second contact 54. When the metal rod 52 rotates to connect the first contact 53, the control circuit controls the vibration table 40 to start again, and the cycle is repeated to stabilize the material amount in the vibration plate 10 within a certain range.

[0035] To facilitate the arrangement of the first contact 53 and the second contact 54 , in this embodiment, the first contact 53 and the second contact 54 are located on the same arc, and the center of the arc is located on the rotation axis of the metal rod 52 .

[0036] In order to facilitate the adjustment of the above range, a counterweight block is also provided on the metal rod 52. The position of the counterweight block on the metal rod 52 can be adjusted along the axial direction of the metal rod 52. Specifically, the counterweight block is a nut 521 threadedly connected to the metal rod 52. In order to prevent the nut 521 from moving due to vibration transmitted by the material, in the present embodiment, there are two nuts 521, which are tightened together to prevent movement.

[0037] The angle between the bottom of the conveying trough 30 and the horizontal plane is preferably 1-4°. The advantage of this setting is that when the conveying trough 30 is stationary, the material on the conveying trough 30 will not move spontaneously. When the conveying trough 30 vibrates, the movement of the material has a certain efficiency. In this embodiment, the angle is 2°.

[0038] The feeding mechanism of the tattoo needle assembly machine provided by the present invention can form an inclined surface inclined toward the vibration plate at the bottom of the conveying trough by making the left end of the conveying trough slightly higher than the right end of the conveying trough, and then connect the left end of the conveying trough with the vibration table, and electrically connect the detection component with the control circuit of the vibration table, so that the amount of material in the vibration plate can be detected in real time by the detection component, and the control circuit controls the vibration table to start or stop according to the detection result, so that the conveying trough follows the vibration to convey the material flowing out of the bottom outlet of the feeding bin to the vibration plate to complete the feeding or stop the feeding, and the feeding timeliness is good. When feeding, the material enters the vibration plate with good balance, and can achieve real consumption and real supplementation. The operation efficiency of the vibration plate is high, saving time and labor, and the efficiency is high.

[0039] It should be noted that, in this document, relational terms such as first and second, etc. are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0040] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the contents of the present invention and implement them accordingly. They cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
