Detailed implementation mode

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-5 , in the embodiment of the present invention, a dispensing device for a speaker based on dispensing flow rate adjustment includes a dispensing cylinder 10, a dispensing head 11, and an anti - coagulation mechanism 20. The anti - coagulation mechanism 20 is arranged inside the dispensing cylinder 10. The anti - coagulation mechanism 20 includes a rotatably arranged outer shaft 22, an inner shaft 21 arranged inside the outer shaft 22, and a flow regulator head 24. It can be understood that the outer shaft 22 has a hollow shaft structure; a sliding sleeve 25 is slidably installed inside the lower end of the outer shaft 22. The lower end of the inner shaft 21 is provided with a threaded section, and the threaded section is threadedly connected to the sliding sleeve 25. The flow regulator head 24 is fixedly connected to the lower end of the sliding sleeve 25. When the inner shaft 21 rotates inside the outer shaft 22, the threaded section adjusts the sliding sleeve 25 to slide along the inner wall of the outer shaft 22, thereby adjusting the up - and - down position of the flow regulator head 24; the flow regulator head 24 has a conical structure, and an outlet with the same shape as the flow regulator head 24 is arranged inside the lower end of the dispensing cylinder 10. When the position of the flow regulator head 24 inside the dispensing cylinder 10 changes, the distance between the flow regulator head 24 and the outlet changes, thereby changing the flow rate of the glue flowing out of the outlet to adjust the dispensing flow rate during the dispensing operation.

[0021] In the embodiment of the present application, an upper cover 12 is provided at the upper end of the dispensing cylinder 10. The upper end of the outer shaft 22 passes through the upper end of the dispensing cylinder 10 and extends into the interior of the upper cover 12. The upper end of the outer shaft 22 is rotatably connected to the dispensing cylinder 10. A first motor 121 and a second motor 122 are fixedly installed on the upper cover 12. The output end of the first motor 121 is fixedly connected to the inner shaft 21. The first motor 121 is used to drive the inner shaft 21 to rotate to adjust the up and down position of the flow rate adjusting head 24. Further, in the embodiment of the present application, a spiral blade 23 is fixedly installed on the outer shaft 22. When the outer shaft 22 rotates, the outer shaft 22 drives the spiral blade 23 to rotate. The spiral blade 23 pushes the glue in the dispensing cylinder 10 to flow, so that the glue flows out from the liquid outlet. During this process, the spiral blade 23 stirs the glue to prevent the glue from solidifying. In the embodiment of the present application, a first gear 123 is fixedly installed on the outer shaft 22. The output end of the second motor 122 is fixedly installed with a second gear 124. The second gear 124 meshes with the first gear 123. It can be understood that the second motor 122 drives the outer shaft 22 to rotate through the first gear 123 and the second gear 124. In addition, a liquid inlet 13 is provided on the dispensing cylinder 10. The liquid inlet 13 is used to inject glue into the interior of the dispensing cylinder 10.

[0022] In the embodiment of the present application, the dispensing head 11 is installed at the liquid outlet of the dispensing cylinder 10. The dispensing head 11 includes a connecting seat 111 and a glue injection head 112. One side of the connecting seat 111 is connected to the dispensing cylinder 10, and the other side of the connecting seat 111 is connected to the glue injection head 112. A glue channel is provided inside the connecting seat 111. The glue channel is used to introduce the glue flowing out of the liquid outlet into the glue injection head 112, so that the glue is discharged from the glue injection head 112.

[0023] Such as Figure 5As shown, a lifting tube 113 and a glue injection tube 114 are arranged inside the glue liquid channel. The glue injection tube 114 is located inside the lifting tube 113, and the lifting tube 113 is slidably connected to the glue liquid channel. The glue injection tube 114 is fixedly connected to the glue injection head 112, and the lower end of the glue injection tube 114 is communicated with the glue injection head 112. At least one glue liquid inlet is formed on the side of the glue injection tube 114. In the initial state, the inner wall of the lifting tube 113 blocks the glue liquid inlet, and the glue liquid cannot enter the inside of the glue injection tube 114. When dispensing glue, the spiral blade 23 pushes the glue liquid inside the dispensing cylinder 10 to flow. The glue liquid flows into the inside of the lifting tube 113 from the liquid outlet. The lifting tube 113 moves downward along the glue liquid channel under the push of the glue liquid, so that the glue liquid inlet on the side of the glue injection tube 114 is exposed. The glue liquid enters the inside of the glue injection head 112 from the glue liquid inlet. After the dispensing is completed, the spiral blade 23 stops rotating, the glue liquid inside the dispensing cylinder 10 is static, and the lifting tube 113 resets after losing the external force, and the glue liquid inlet is blocked again, avoiding the leakage of the glue liquid after the dispensing is completed, thereby improving the dispensing effect. Further, in the embodiment of the present application, a chute is formed inside the glue liquid channel, a slider 115 is slidably installed inside the chute, the slider 115 is fixedly connected to the outer wall of the lifting tube 113, and the slider 115 is also connected to one side of the chute through a return spring 116. The slider 115 and the return spring 116 are used to drive the lifting tube 113 to reset.
