Technical Field

[0001] This utility model relates to a surface grinding device for processing plastic caps, and more particularly to a surface grinding device for processing plastic caps used in the field of grinding. Background Technology

[0002] Sanding plastic caps is a very important post-processing step. It can remove a series of surface defects such as parting lines, burrs, and gate marks generated during the injection molding or processing of plastic caps. It can also improve the feel and safety of use, avoid scratches from burrs, and finally provide a smooth base to prepare for subsequent secondary processing. Therefore, surface sanding is indispensable when processing plastic caps.

[0003] Chinese patent CN219380200U discloses a surface polishing device for plastic products, which uses two oppositely arranged lead screws to achieve clamping operation and uses a fan to achieve dust extraction.

[0004] Chinese patent CN219005573U discloses a ring-shaped surface grinding device for processing plastic caps. It uses a bidirectional screw for clamping and replaceable grinding brushes to allow for changing the grinding brush according to the different diameters of the bottle cap body. This reduces the labor intensity of workers, increases grinding efficiency, and facilitates fixing bottle cap bodies of different diameters.

[0005] In the aforementioned plastic cap grinding equipment, dust removal can be achieved through a suction fan. However, in actual operation, due to the inconsistent size of the grinding debris, some larger debris is trapped on the surface of the workbench and cannot be sucked away, thus affecting the quality of the cleaning operation on the workbench surface. Utility Model Content

[0006] The technical problem to be solved by this utility model is that the size difference of the grinding debris causes debris to remain on the surface of the grinding table during suction, resulting in incomplete cleaning.

[0007] To address the aforementioned problems, this utility model provides a surface polishing device for plastic caps, including a polishing table. The surface of the polishing table has multiple through slots. A support column is slidably connected to the centrally located through slot. A clamping plate, slidably arranged on the surface of the polishing table, is fixedly connected to the top of the support column. A soft pad is arranged on the surface of the clamping plate. A hydraulic cylinder is installed on the top of the polishing table. The output end of the hydraulic cylinder is connected to a base plate. Multiple rotating discs with anti-slip textures are rotatably connected to the top of the base plate. The rotating discs at both ends are connected by a transmission belt. A linkage rod extending to the bottom of the base plate is fixedly installed inside the rotating disc. A polishing block is connected to the tail end of the linkage rod. An electric push rod is installed on one side of the polishing table. The power end of the electric push rod extends through the interior of the polishing table and is connected to a cleaning push plate. A cleaning mechanism and a drive mechanism for driving the clamping plate are installed in the inner cavity of the polishing table.

[0008] In the aforementioned plastic cap processing surface polishing equipment, the surface of the polishing table is effectively removed by using a suction operation and a cleaning push plate to push and clean the surface of the polishing table.

[0009] As a further improvement of this application, the cleaning mechanism includes a suction fan installed in the inner cavity of the polishing table and an inclined filter screen, wherein the suction fan is located below the filter screen.

[0010] As a further improvement of this application, the drive mechanism includes a rotary motor installed in the inner cavity of the grinding table. The output end of the rotary motor is connected to a bidirectional screw located above the filter screen. A movable block is threaded onto the surface of the bidirectional screw, and the top of the movable block is fixedly connected to the bottom of the support column.

[0011] As a further improvement of this application, a discharge port is provided through one inner wall of the grinding table, and the cross-sectional dimensions of the discharge port are the same as those of the cleaning push plate. A collection frame is arranged on the other side of the grinding table.

[0012] As a further improvement of this application, the cross-sectional width of the through groove is less than 2cm, and the length of the through groove is not less than the length of the bidirectional screw.

[0013] As a further improvement of this application, a drive motor is mounted on one end of the top of the base plate via a bracket, and the output end of the drive motor is connected to one of the rotating disks. The connection position between the bracket and the base plate is offset from the movement path of the conveyor belt.

[0014] As another improvement of this application, in the initial state, the cleaning push plate is located on one side of the clamping plate, and the surface of the cleaning push plate is coated with an anti-stick coating. The interior of the cleaning push plate is provided with a strip groove with the same thickness as the clamping plate, and the cross-sectional length of the cleaning push plate is the same as the length of the through groove.

[0015] As a further improvement to this application, the back of the grinding table is provided with a movable groove, the tail end of the filter screen contacts the bottom of the movable groove, and a dust collection frame located below the movable groove is detachably installed on the back of the grinding table.

[0016] In summary, this application utilizes an adjustable clamping plate to stabilize the plastic cap to be processed, and uses the synchronous rotation of multiple grinding heads to perform uniform surface treatment, ensuring consistent processing quality. In addition, the cleaning operation, which combines suction and cleaning push plate to clean the surface of the grinding table, can effectively remove debris generated during the grinding process, avoiding the impact of impurities on processing accuracy, maintaining the cleanliness of the worktable, and ensuring the reliability of subsequent operations.

[0019] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0020] First implementation method: Figures 1-5A surface polishing device for processing plastic caps is shown, including a polishing table 1. The surface of the polishing table 1 is provided with multiple through grooves 10. A support column is slidably connected to the centrally located through groove 10. A clamping plate 5 is slidably arranged on the surface of the polishing table 1 and fixedly connected to the top of the support column. The surface of the clamping plate 5 is provided with a soft pad. A hydraulic cylinder 3 is installed on the top of the polishing table 1. The output end of the hydraulic cylinder 3 is connected to a base plate 4. Multiple rotating disks 11 with anti-slip textures are rotatably connected to the top of the base plate 4. The rotating disks 11 at both ends are connected by a transmission belt 12. A linkage rod 71 extending to the bottom of the base plate 4 is fixedly installed through the interior of the rotating disk 11. A polishing block 7 is connected to the tail end of the linkage rod 71. An electric push rod 2 is installed on one side of the polishing table 1. The power end of the electric push rod 2 extends through the interior of the polishing table 1 and is connected to a cleaning push plate 17. A cleaning mechanism and a drive mechanism for driving the clamping plate 5 are installed in the inner cavity of the polishing table 1.

[0021] The cleaning mechanism includes a suction fan 13 installed in the inner cavity of the polishing table 1 and an inclined filter screen 14, wherein the suction fan 13 is located below the filter screen 14.

[0022] The drive mechanism includes a rotary motor 15 installed in the inner cavity of the grinding table 1. The output end of the rotary motor 15 is connected to a bidirectional screw 16 located above the filter screen 14. A movable block is threaded onto the surface of the bidirectional screw 16, and the top of the movable block is fixedly connected to the bottom of the support column.

[0023] A discharge port 8 is provided through one inner wall of the grinding table 1, and the cross-sectional dimensions of the discharge port 8 are the same as those of the cleaning push plate 17. A collection frame 9 is arranged on the other side of the grinding table 1.

[0024] The cross-sectional width of the through groove 10 is less than 2cm, and the length of the through groove 10 is not less than the length of the bidirectional screw 16.

[0025] Specifically, when grinding the plastic cap, the plastic cap needs to be placed on the surface of the grinding table 1. Then, by using the cooperation of the rotating motor 15 and the bidirectional screw 16, the two clamping plates 5 are driven to move closer to each other, thereby clamping and constraining the plastic cap placed on the surface of the grinding table 1.

[0026] Then, the hydraulic cylinder 3 drives the base plate 4 to descend, allowing the grinding block 7 to descend and fit against the surface of the plastic cover. Then, the drive motor 6 is started, driving the rotating disk 11 connected to it to rotate. Through the transmission action of the conveyor belt 12 (the surface in contact with the rotating disk 11 is arranged with anti-slip texture to increase friction), multiple grinding blocks 7 can rotate synchronously to grind the top surface of the constrained plastic cover.

[0027] During the polishing process, the suction fan 13 is activated simultaneously, allowing some of the debris generated during polishing to be drawn through the channel 10 to the surface of the filter screen 14. The remaining debris remains on the surface of the polishing table 1 between adjacent channels 10. At this point, a single suction operation cannot remove the debris remaining on the surface of the polishing table 1 (because the cross-sectional width of the channel 10 is less than 2cm, larger debris can pass through, but the debris remaining on the surface of the polishing table 1 is difficult to remove due to obstruction, and the plastic cap is difficult to fall through the channel 10). Therefore, after polishing, the hydraulic cylinder 3 is used to lift the base plate 4 and stop the rotation of the polishing block 7. The rotating motor 15 is used to reset the clamping plate 5, creating space for the cleaning push plate 17 to push and clean, so that the surface of the plastic cap is no longer clamped. The electric push rod 2 is activated, moving the cleaning push plate 17 along the direction of the discharge port 8 (e.g., ...). Figure 6 As shown, the polished plastic cover is pushed close to the discharge port 8. Because the size of the plastic cover is larger than that of the through groove 10, the plastic cover can move stably as it approaches the discharge port 8. During this process, the debris remaining on the surface of the polishing table 1 between the two through grooves 10 can be pushed into the through groove 10, thereby achieving supplementary cleaning of the surface of the polishing table 1 and ensuring the quality of the surface cleaning work of the polishing table 1.

[0028] After passing through the discharge port 8, the polished plastic cap is transferred to the collection frame 9 to complete the collection operation. After the collection is completed, the collection frame 9 is moved using the rollers installed at the bottom.

[0029] A drive motor 6 is mounted on one end of the top of the base plate 4 via a bracket, and the output end of the drive motor 6 is connected to one of the rotating disks 11. The connection position between the bracket and the base plate 4 is offset from the movement path of the conveyor belt 12.

[0030] Specifically, the drive motor 6 provides power for the rotation of the rotating disk 11, and because the bottom of the bracket will not interfere with the conveyor belt 12, the normal operation of the conveyor belt 12 is guaranteed.

[0031] The back of the grinding table 1 is provided with a movable groove 19, the tail end of the filter screen 14 contacts the bottom of the movable groove 19, and a dust collection frame 20 located below the movable groove is detachably installed on the back of the grinding table 1.

[0032] Specifically, the inclined filter screen 14 can easily transfer most of the debris to the inside of the dust collection frame 20 during filtration, and the dust collection frame 20 is detachably connected to the surface of the grinding table 1 (it can be plug-in or other methods), which facilitates the transfer of the dust collection frame 20.

[0033] Second implementation method: Figure 7As shown, in the initial state, the cleaning push plate 17 is located on one side of the clamping plate 5, and the surface of the cleaning push plate 17 is coated with an anti-stick coating. The interior of the cleaning push plate 17 is provided with a strip groove 18 with the same thickness as the clamping plate 5, and the cross-sectional length of the cleaning push plate 17 is the same as the length of the through groove 10.

[0034] Unlike the first embodiment, this embodiment further restricts the cleaning push plate 17 so that the cleaning push plate 17 can thoroughly push and clean the surface of the through groove 10 during operation.

[0035] Specifically, in the first embodiment, when the clamping plate 5 is reset, it needs to be reset to the farthest distance. At this time, the clamping plate 5 and the strip groove 18 are on the same axis. When the cleaning push plate 17 moves in the future, it can slide across the surface of the clamping plate 5 and push and clean the surface of the grinding table 1 between the two clamping plates 5.

[0036] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
