[0007] The effect achieved by the above components is as follows: by setting up a polishing device, it is easy to adjust the height of the polishing sandpaper, thereby facilitating the polishing of hinge heads of different sizes and thicknesses, thus ensuring the quality of the hinge head polishing and improving its durability and appearance quality.

[0008] Preferably, the inner wall of the groove is provided with a plurality of circular grooves, and a plurality of conical blocks are fixedly connected to the surface of the pressure plate, the size of the conical blocks being adapted to the size of the circular grooves.

[0009] The effect achieved by the above components is as follows: when the pressure plate moves, it will drive the conical block to move. After the conical block moves to the appropriate position, it will pierce the sandpaper. After the pressure plate moves to the appropriate position, the conical block will insert into the circular groove. The conical block achieves the function of raising the pressure plate to limit the position of the sandpaper.

[0010] Preferably, a turntable is fixedly connected to the end of the lead screw away from the support, and the cross-section of the turntable is in the shape of a cross.

[0011] The effect achieved by the above components is that the rotation of the turntable will drive the lead screw to rotate, and the turntable facilitates the rotation of the lead screw.

[0012] Preferably, two limiting rods slide through the surface of the U-shaped plate, and a rectangular hole is provided on the surface of the connecting plate. A limiting strip is slidably connected to the inner wall of the rectangular hole, and the limiting strip is fixedly connected to the limiting rods.

[0013] The effects achieved by the above components are as follows: when the connecting plate moves, it will drive the limiting strip to move; when the limiting strip moves, it will drive the limiting rod to slide inside the U-shaped plate; when the connecting plate moves, it will cause the limiting strip to slide inside the rectangular hole; the limiting strip will prevent the rectangular plate from rotating when it moves; and the limiting rod will prevent the rectangular plate from rotating when it moves towards the base plate.

[0014] Preferably, the surface of the base plate is provided with a cleaning device, the cleaning device including a through hole, the through hole being opened on the surface of the base plate, a round rod being slidably inserted into the surface of the base plate, one end of the round rod being fixedly connected to a push plate, the push plate being slidably connected to the inner wall of the through hole, and a filter screen being fixedly connected to the inner wall of the through hole.

[0015] The effect achieved by the above components is as follows: by setting up a cleaning structure, it is possible to collect the debris generated during the polishing of the hinge head, thereby preventing debris from accumulating on the surface of the base plate and affecting the movement of the hinge head on the surface of the base plate, thus ensuring the polishing effect of the hinge head.

[0016] Preferably, a cleaning plate is fixedly connected to the surface of the push plate, and a plurality of bristles are fixedly connected to the surface of the cleaning plate.

[0020] In summary:

[0021] 1. In this utility model, by setting a polishing device, the rotation of the lead screw slides within the U-shaped plate via the thread. The movement of the lead screw drives the movement of the bracket, which in turn drives the movement of the servo motor. The movement of the servo motor drives the limit ring to move closer to the base plate, which in turn drives the movement of the connecting plate. The movement of the connecting plate drives the rectangular plate to move closer to the base plate, which in turn drives the sandpaper to adhere to the surface of the hinge head. The servo motor drives the servo motor, which in turn drives the gear disk to rotate repeatedly in both directions. The rotation of the gear disk drives the sawtooth plate to move via the teeth, which in turn drives the rectangular plate to move. The movement of the rectangular plate drives the sandpaper to move along the surface of the hinge head, and then pushes the hinge head to slide on the surface of the base plate at a uniform speed. This allows the sandpaper to rub and polish the surface of the hinge head back and forth, making it easy to adjust the height of the polishing sandpaper and thus easy to polish hinge heads of different sizes and thicknesses.

[0022] 2. In this utility model, by setting up a cleaning device, when polishing the hinge head, the debris generated during polishing will fall onto the surface of the base plate. The debris will pass through the filter screen on the surface of the base plate and fall into the through hole. When the surface of the hinge head is polished, the round rod is pressed, and the movement of the round rod will drive the push plate to move. When the pressing rod moves, it will drive the push plate to move. The push plate will slide in the through hole, thereby gradually pushing out the debris collected in the through hole. When the push plate moves to a suitable position, the push plate will remove the debris from the through hole, thus facilitating the cleaning of the debris generated during polishing of the hinge head, avoiding the accumulation of debris on the surface of the base plate, which would affect the movement of the hinge head on the surface of the base plate, and thus ensuring the polishing effect of the hinge head.

[0031] Reference Figure 1 As shown, this utility model provides a technical solution: a container hinge polishing structure, including a base plate 1 and a hinge head 2. The surface of the base plate 1 is provided with a polishing device 3. By setting the polishing device 3, the height of the polishing sandpaper can be easily adjusted, thus facilitating the polishing of hinge heads 2 of different sizes and thicknesses, thereby ensuring the quality of polishing the hinge head 2 and improving its durability and appearance. The surface of the base plate 1 is provided with a cleaning device 4. By setting the cleaning structure, it is possible to collect the debris generated during the polishing of the hinge head 2, thereby preventing debris from accumulating on the surface of the base plate 1 and affecting the movement of the hinge head 2 on the surface of the base plate 1, thus ensuring the polishing effect of the hinge head 2.

[0032] The specific setup and function of the polishing device 3 and the cleaning device 4 will be described in detail below.

[0033] Reference Figure 2 - Figure 6As shown in this embodiment: the polishing device 3 includes a U-shaped plate 301, which is fixedly connected to the surface of the base plate 1. A lead screw 302 is threaded through the surface of the U-shaped plate 301. A bracket 303 is rotatably connected to one end of the lead screw 302 near the base plate 1. A servo motor 304 is fixedly connected to the surface of the bracket 303. A gear disk 305 is fixedly connected to the output end of the servo motor 304. Two limiting rings 306 are sleeved on the output end of the servo motor 304. Two connecting plates 307 are fixedly connected to the surface of the limiting rings 306. A rectangular plate 308 is fixedly connected to the side of the connecting plate 307 away from the limiting plate. A serrated plate 309 is fixedly connected to the surface of the rectangular plate 308. The serrated plate 309 meshes with the gear disk 305. Grooves 310 are provided on both sides of the rectangular plate 308. Two threaded rods 311 are threadedly connected to the surface of the rectangular plate 308. A pressure plate 312 is slidably connected to the inner wall of the groove 310. The threaded rods 311 are rotatably connected to the surface of the pressure plate 312. The inner wall of the groove 310 has several circular grooves 314. Several conical blocks 313 are fixedly connected to the surface of the pressure plate 312. The size of the conical blocks 313 matches the size of the circular grooves 314. When the pressure plate 312 moves, it will drive the conical blocks 313 to move. After the conical blocks 313 move to the appropriate position, they will pierce the sandpaper. After the pressure plate 312 moves to the appropriate position, the conical blocks 313 will insert into the circular grooves 314. The conical blocks 313 achieve the function of raising the pressure plate 312 to limit the position of the sandpaper. A turntable 315 is fixedly connected to the end of the lead screw 302 away from the bracket 303. The cross-section of the turntable 315 is cross-shaped. The rotation of the turntable 315 will drive the lead screw 302 to rotate. The turntable 315 facilitates the rotation of the lead screw 302. Two limiting rods 316 slide through the surface of the U-shaped plate 301. A rectangular hole 318 is provided on the surface of the connecting plate 307. A limiting strip 317 is slidably connected to the inner wall of the rectangular hole 318. The limiting strip 317 is fixedly connected to the limiting rod 316. When the connecting plate 307 moves, it will drive the limiting strip 317 to move. The movement of the limiting strip 317 will drive the limiting rod 316 to slide within the U-shaped plate 301. When the connecting plate 307 moves, it will cause the limiting strip 317 to slide within the rectangular hole 318. The limiting strip 317 achieves the function of preventing the rectangular plate 308 from rotating when it moves. The limiting rod 316 achieves the function of preventing the rectangular plate 308 from rotating when it moves towards the base plate 1.

[0034] Reference Figure 2 and Figure 7As shown, specifically, the cleaning device 4 includes a through hole on the surface of the base plate 1. A round rod 42 is slidably inserted into the surface of the base plate 1. One end of the round rod 42 is fixedly connected to a push plate 43, which is slidably connected to the inner wall of the through hole. A filter screen 47 is fixedly connected to the inner wall of the through hole. A cleaning plate 44 is fixedly connected to the surface of the push plate 43, and several bristles 45 are fixedly connected to the surface of the cleaning plate 44. When the push plate 43 moves, it drives the cleaning plate 44 to move. The movement of the cleaning plate 44 drives the bristles 45 to slide along the surface of the filter screen 47. The bristles 45 facilitate the removal of debris stuck in the holes on the surface of the filter screen 47, thereby further improving the cleaning effect of debris. A spring 46 is sleeved on the arc surface of the round rod 42. The two ends of the spring 46 are fixedly connected to the round rod 42 and the base plate 1, respectively. The round rod 42 will drive the push plate 43 to reset with the help of the extension force of the spring 46. The spring 46 restricts the position of the round rod 42, thereby facilitating the reset of the push plate 43.

[0035] Working principle: When polishing the hinge head 2, first, sandpaper is attached to the surface of the rectangular plate 308 near the base plate 1. Then, both sides of the sandpaper are placed in the groove 310. Rotating the threaded rod 311 causes it to move within the rectangular plate 308 via the thread. This movement of the threaded rod 311 moves the pressure plate 312 towards the sandpaper. The movement of the pressure plate 312 moves the conical block 313. Once the conical block 313 reaches the appropriate position, it pierces the sandpaper. After the pressure plate 312 reaches the appropriate position, it squeezes the sandpaper. When the conical block 313 reaches the inner wall of the groove 310, it will insert into the circular groove 314. The pressure plate 312 will then limit the position of the sandpaper. The conical block 313 will raise the pressure plate 312 to limit the position of the sandpaper. Place the hinge head 2 on the surface of the base plate 1 and then rotate the turntable 315. The rotation of the turntable 315 will drive the lead screw 302 to rotate. The rotation of the lead screw 302 will slide within the U-shaped plate 301 by means of the thread. The movement of the lead screw 302 will drive the support 303 to move. The movement of the support 303 will drive the servo motor 304 to move. The movement of the servo motor 304 will drive the limiting ring 306 to move closer to the base plate 1. The movement of the limiting ring 306 causes the connecting plate 307 to move, which in turn causes the rectangular plate 308 to move closer to the base plate 1. The movement of the connecting plate 307 causes the limiting strip 317 to move, which in turn causes the limiting rod 316 to slide within the U-shaped plate 301. When the rectangular plate 308 moves to the appropriate position, it causes the sandpaper to adhere to the surface of the hinge head 2, driving the servo motor 304. The rotation of the servo motor 304 causes the gear disk 305 to rotate repeatedly in both directions. The rotation of the gear disk 305, through its teeth, causes the sawtooth plate 309 to move. The movement of the sawtooth plate 309 causes the rectangular plate 308 to move, which in turn causes the connecting plate 307 to move. The movement of the connecting plate 307 causes the limiting ring 306 to slide on the surface of the output end of the servo motor 304. When the connecting plate 307 moves, the limiting strip 317 slides within the rectangular hole 318. The limiting strip 317 prevents the rectangular plate 308 from rotating during movement. The movement of the rectangular plate 308 causes the sandpaper to move along the surface of the hinge head 2, and then pushes the hinge head 2 to slide on the surface of the base plate 1 at a uniform speed, thereby causing the sandpaper to rub and polish the surface of the hinge head 2 back and forth.

[0036] When polishing the hinge head 2, the polishing debris will fall onto the surface of the base plate 1. The debris will pass through the filter screen 47 on the surface of the base plate 1 and fall into the through hole. When the surface of the hinge head 2 is polished, press the round rod 42. The movement of the round rod 42 will drive the push plate 43 to move. When the round rod 42 moves, it will compress the spring 46. The movement of the push rod will drive the push plate 43 to move. The push plate 43 will slide in the through hole, thereby gradually pushing out the debris collected in the through hole. When the push plate 43 moves, it will drive the cleaning plate 44 to move. The movement of the brush 45 will cause the brush bristles 45 to slide along the surface of the filter screen 47, so that the brush bristles 45 can easily remove the debris stuck in the holes on the surface of the filter screen 47, thereby further improving the cleaning effect of the debris. When the push plate 43 moves to the appropriate position, the push plate 43 will remove the debris from the through hole, so as to facilitate the cleaning of the debris generated during the polishing of the polishing head 2. Then, the round rod 42 is released, and the round rod 42 will drive the push plate 43 to return to its original position with the help of the extension force of the spring 46. The spring 46 can limit the position of the round rod 42, thereby facilitating the return of the push plate 43 to its original position.
