[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0026] Some embodiments of this utility model are described below with reference to the accompanying drawings.

[0027] Example 1:

[0028] Combination Figure 1-6 As shown, this embodiment provides a microphone head sealing device, including: a main body mechanism 100 and a feeding mechanism 200.

[0029] The main structure 100 includes a base 110, columns 120 fixed in a circular array on the base 110, a top plate 130 fixed to the top of the column 120, a movable seat 140 slidably sleeved on the column 120, a rolled edge sealing device 150 fixed in a circular array on the outer side of the movable seat 140, a hydraulic rod 160 fixed on the top plate 130 and fixedly connected to the movable seat 140, a turntable 170 rotatably sleeved on the base 110, a delivery component 180 fixed on the base 110 and located above the turntable 170, and a drive component 190 fixed to one side of the delivery component 180.

[0030] The base 110 is used to fix the column 120 and ensure the stability of the column 120. The column 120 is used to install the movable seat 140 and limit the movement of the movable seat 140 to ensure the stability of the movable seat 140 when moving up and down. The top plate 130 is used to install the hydraulic rod 160. The hydraulic rod 160 is used to drive the movable seat 140 to move up and down. The up and down movement of the movable seat 140 drives the sealing and rolling device to move up and down to roll and seal the microphone.

[0031] The turntable 170 includes an annular disk 171 rotatably sleeved on the outside of the base 110 and a toothed ring 172 fixed on the outside of the annular disk 171. An annular protrusion is provided on the inner side of the annular disk 171, and an annular groove is provided on the outer side of the base 110. The annular protrusion is rotatably fitted into the annular groove to ensure the stability of the annular disk 171 when rotating.

[0032] The feeder 180 is used to feed the microphones on the annular plate 181. It includes an annular plate 181 fixed on the base 110 and located above the annular disk 171, a guide plate 182 extending outward through the annular plate 181, and a discharge conveyor belt 183 installed on the guide plate 182. The annular plate 181 is divided into inner and outer parts. The inner annular plate 181 is close to the inner edge of the annular disk 171, and the outer annular plate 181 is close to the outer edge of the annular disk 171. It limits the microphones on the annular disk 171 to prevent the microphones from being thrown out during the rotation of the annular disk 171. One side of the guide plate 182 is connected to the inner and outer annular plates 181, and the other side extends outward from the outer annular plate 181 to discharge the microphones on the annular disk 171. The discharge conveyor belt 183 is used to feed the sealed microphones out.

[0033] The driving component 190 is used to drive the annular disk 171 to rotate. It includes a motor 191 fixed on the feeder 180 and a gear 192 fixed on the shaft of the motor 191. The gear 192 meshes with the gear ring 172, so that when the motor 191 rotates, it drives the gear 192 to rotate. The rotation of the gear 192 drives the gear ring 172 to rotate, which in turn drives the annular disk 171 to rotate.

[0034] The feeding mechanism 200 includes a placement seat 210 fixed in a circular array on the base 110, a positioning seat 220 fixed at the top of the placement seat 210, a feeding conveyor belt 230 installed on one side of the positioning seat 220, a pusher 240 installed at the bottom of the placement seat 210 and passing through the feeding conveyor belt 230, and a discharger 250 installed on one side of the placement seat 210.

[0035] One side of the placement seat 210 is fixed to the top of the base 110 by a bracket to ensure its stability. The positioning seat 220 is used to position the microphone to ensure that the microphone is directly below the edge sealing device 150. The feeding conveyor belt 230 is used to transport the microphone that needs to be sealed.

[0036] The pusher 240 is used to push the microphone on the feed conveyor belt 230 into the placement seat 210 and fix it in place with the positioning seat 220. The pusher 240 includes a first electric telescopic rod 241 fixed at the bottom of the placement seat 210 and a push plate 242 that passes through the feed conveyor belt 230 and is fixedly connected at its end to the end of the first electric telescopic rod 241. When the first electric telescopic rod 241 is activated, it can drive the push plate 242 to move and push the microphone at the outermost edge of the feed conveyor belt 230 into the placement seat 210, where it is fixed in place with the positioning seat 220 to ensure the stability of the microphone.

[0037] An opening 211 is provided on the placement seat 210 for discharging the sealed microphone, so that the sealed microphone can fall into the annular disc 171 through the opening 211. The discharge component 250 includes a baffle 251 that is slidably fitted into the opening 211 and a second electric telescopic rod 252 that is fixed to one side of the placement seat 210 and whose end is fixedly connected to the baffle 251. A sliding groove is opened on the opposite inner wall of the opening 211, and protrusions are provided on both sides of the baffle 251, and the protrusions are fitted into the sliding groove to ensure the stability of the baffle 251 in the opening 211. The second electric telescopic rod 252 is used to drive the baffle 251 to move, thereby controlling the opening and closing of the opening 211.

[0038] The working principle and usage process of this utility model are as follows: During use, the feeding conveyor belt 230 rotates to feed materials. Simultaneously, the first electric telescopic rod 241 is activated, driving the push plate 242 to push the microphones on the feeding conveyor belt 230 into the placement seat 210, and cooperating with the positioning seat 220 to fix the microphones. Then, the hydraulic rod 160 drives the movable seat 140 to move downwards. The downward movement of the movable seat 140 drives multiple edge-sealing devices 150 to move downwards, simultaneously sealing multiple microphones. After the microphones are sealed, the second electric telescopic rod is activated, driving the baffle 251 to... The external movement opens the opening 211 on the placement seat 210. At this time, the first electric telescopic rod 241 drives the push plate 242 to reset. The sealed microphone falls into the annular disk 171 through the opening 211. The motor 191 starts and drives the gear 192 to rotate. The rotation of the gear 192 drives the toothed ring 172 to rotate. The rotation of the toothed ring 172 drives the annular disk 171 to rotate, which in turn drives the microphone on the annular disk 171 to rotate. The microphone rotates with the annular disk 171 and enters the discharge conveyor belt 183 for discharge under the action of the discharge plate 182.
