Description

Technical Field

[0001] The utility model relates to the technical field of grinding, in particular to an annular surface grinding device for processing plastic covers. Background Art

[0002] Plastic caps are mostly made directly by injection molding machines and used on plastic barrels to seal the plastic barrels. After the plastic caps are produced, there will be many burrs on their outer surface. If they are not cleaned, it will affect their use. Therefore, after the plastic caps are processed and produced, they must be polished to remove the burrs for later use.

[0003] At present, the plastic cover is polished manually. Since the inner side of the plastic cover is concave, in order to facilitate the removal of burrs on the side, the staff needs to use a grinding block to continuously polish the burrs on the side of the plastic cover to remove the burrs and ensure the smoothness of the side of the plastic cover.

[0004] Although the above method can remove burrs, there are a large number of plastic caps in the factory production. Only grinding by the staff will increase the labor intensity of the staff. At the same time, powder will appear in the grinding process, which will affect the respiratory system of the staff. Therefore, we propose a ring surface grinding device for plastic cap processing to solve the above problems. Utility Model Content

[0028] Example

[0029] Reference Figure 1-Figure 6The utility model provides a technical solution: a ring-shaped surface grinding device for processing plastic covers, comprising a processing plate 1 and a grinding mechanism 3, the upper surface of the processing plate 1 is rotatably mounted on a placement disk 2, the grinding mechanism 3 comprises a mounting frame 31, a positioning block 311 is arranged on the upper surface of the placement disk 2, the inner part of the positioning block 311 is slidably connected to the mounting frame 31, a grinding block 32 is mounted at a position inside the mounting frame 31, the bottom of the processing plate 1 is fixedly connected to a driving motor 33, the output end of the driving motor 33 is fixedly connected to a transmission rod 331, and the transmission rod 331 is fixedly connected to the placement disk 2.

[0030] In a preferred embodiment, a sliding groove 4 is provided on the inner side of the mounting frame 31, and a mounting block 5 is clamped inside the sliding groove 4. One side of the mounting block 5 is fixedly connected to a rectangular plate 6, and a grinding block 32 is bonded to one side of the rectangular plate 6. In order to facilitate the replacement of the grinding block 32 and replace the grinding block 32 with more wear in time to ensure the grinding effect of the plastic cover, a sliding groove 4 is provided on the inner side of the mounting frame 31, and a mounting block 5 is clamped inside the sliding groove 4. The mounting block 5 is pushed into the sliding groove 4 and the movement of the mounting block 5 is stopped, so that the mounting block 5 can be stably clamped inside the sliding groove 4, so that the grinding block 32 can be stably installed at the position inside the mounting frame 31, and the grinding block 32 can stably grind the plastic cover.

[0031] In a preferred embodiment, the upper surface of the processing plate 1 is fixedly connected to the annular plate 7, and the placement plate 2 is arranged at a position inside the annular plate 7. During the grinding process of the plastic cover, waste will fall onto the plastic cover, and the waste on the plastic cover is cleaned by a cleaning brush 112. In order to prevent the waste from being swept everywhere and affecting the surrounding environment, the annular plate 7 is fixedly connected to the upper surface of the processing plate 1 to shield the waste and prevent it from falling to the ground.

[0032] In a preferred embodiment, a groove is opened on the top of the positioning block 311, and a spring 8 is fixedly connected inside the groove. One end of the spring 8 is fixedly connected to the mounting frame 31. In order to enable the mounting frame 31 to stably cover the plastic cover and stably polish the plastic cover, a spring 8 is installed inside the positioning block 311. The spring 8 enables the mounting frame 31 to stably cover the plastic cover so that the plastic cover can be stably polished for use.

[0033] At the same time, in order to prevent the mounting frame 31 from jumping when grinding the plastic cover, a plurality of through holes 9 are opened on the outer surface of the mounting frame 31, and a threaded hole is opened on the outer surface of the positioning block 311. The inner thread of the threaded hole is connected to the screw 10, and the screw 10 is inserted into the inner part of the through hole 9. When the mounting frame 31 is covered on the plastic cover, the screw 10 can be screwed into the inner part of the mounting frame 31, so as to position the mounting frame 31, so that the mounting frame 31 can be stably used to grind the plastic cover, which is convenient for use.

[0034] The plastic cover is polished by the mounting frame 31, and the waste generated by the polishing will fall onto the plastic cover. In order to facilitate the cleaning of the waste, a cleaning mechanism 11 is installed on the processing plate 1, and the cleaning mechanism 11 includes a cylinder 111, a cleaning brush 112 and a rotating block 113. The upper surface of the processing plate 1 is fixedly connected to the support frame 12, and the top of the support frame 12 is fixedly connected to the cylinder 111. The telescopic end of the cylinder 111 is fixedly connected to the cylindrical rod 13, and the bottom end of the cylindrical rod 13 is rotatably connected to the rotating block 113. The outer surface of the rotating block 113 is fixedly connected to the mounting plate 14, and one side of the mounting plate 14 is connected to the cleaning brush 113. The brush 112 is fixedly connected, and the outer surface of the mounting frame 31 is fixedly connected to the push rod 15, and the position of the push rod 15 corresponds to the position of the mounting plate 14. In actual use, a rotating block 113 is rotatably installed at the bottom end of the cylindrical rod 13, and the mounting plate 14 is installed on the outer surface of the rotating block 113. A cleaning brush 112 is installed at the bottom of the mounting plate 14, and a push rod 15 is installed on the mounting frame 31 at the same time. By rotating the mounting frame 31, the push rod 15 is driven to rotate, and the cleaning brush 112 can be driven to clean the plastic cover, so that the waste on the plastic cover can be cleaned off in time, and the plastic cover can be kept clean.

[0035] Specifically, the working process or working principle of a ring-shaped surface grinding device for processing plastic covers is as follows: the current method of grinding plastic covers is to grind them manually. Since the inner side of the plastic cover is in a concave state, in order to facilitate the removal of burrs on the side, the staff needs to use a grinding block 32 to continuously grind the burrs on the side of the plastic cover to remove the burrs and ensure the smoothness of the side of the plastic cover.

[0036] Although the above method can remove burrs, there are a large number of plastic covers in the factory production. If the staff only polishes them, the labor intensity of the staff will increase. At the same time, powder will appear during the polishing process, which will affect the respiratory system of the staff. Therefore, the present device is designed to solve this problem. The external power supply is connected, and the plastic cover is placed on the upper surface of the placement plate 2. At the same time, the mounting frame 31 is pulled to move the mounting frame 31 upward so that the plastic cover can be placed on the upper surface of the placement plate 2, and the position on the plastic cover that needs to be polished corresponds to the position of the mounting frame 31. After determining the position of the plastic cover, the mounting frame 31 can be controlled to move downward, and the polishing block 32 can be attached to the position on the plastic cover that needs to be polished. The present device sets two mounting frames 31, and three polishing blocks 32 are respectively installed on the inner side of each mounting frame 31, and are respectively arranged on the side and top of the polishing position of the plastic cover.

[0037] Then, the cylinder 111 is opened, and the telescopic end of the cylinder 111 is used to push the cylindrical rod 13 downward and press against the plastic cover, so that the plastic cover is stably placed on the upper surface of the placement tray 2. At the same time, the mounting plate 14 is also moved to the position corresponding to the push rod 15, and the placement tray 2 is driven to rotate by the driving motor 33. Since the plastic cover is pressed by the cylindrical rod 13, it will not rotate with the placement tray 2. The rotation of the placement tray 2 will drive the mounting frame 31 to rotate, and the plastic cover is continuously polished by the rotation of the polishing block 32, so as to remove the burrs on the plastic cover.

[0038] When the placement plate 2 rotates, the positioning block 311 and the mounting frame 31 are driven to rotate, thereby driving the push rod 15 to rotate. By pushing the mounting plate 14 to rotate through the push rod 15, the cleaning brush 112 can be driven to rotate. When the cylindrical rod 13 of the device is pressed against the plastic cover, the cleaning brush 112 will contact the outer surface of the plastic cover. By pushing the mounting plate 14 to rotate through the push rod 15, the cleaning brush 112 is controlled to rotate, and the waste material falling on the plastic cover can be cleaned up, keeping the plastic cover clean, thereby meeting the use requirements.

[0039] It should be noted that the drive motor 33 and the cylinder 111 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they are not described in detail.
