Description

Technical Field

[0001] The present application relates to the technical field of plastic processing, and in particular to a plastic shell processing and edging device. Background Art

[0002] When the edge of the plastic shell is being polished, the polishing head is not easy to fit the edge of the plastic shell, resulting in poor polishing effect.

[0003] In this regard, China's patent application number CN202220659725.1 discloses a plastic shell edge grinding device. The solution mainly uses a spring to push an arc-shaped vibrating grinding plate against the edge of the plastic shell, and grinds as the plastic shell rotates, achieving a better grinding effect.

[0004] However, when the length of the spring changes, the thrust generated is different. If the plastic shell fluctuates too much, the protruding parts will be worn too much, while the concave parts will not be polished enough, resulting in poor overall polishing effect. Summary of the invention

[0009] In the above implementation process, the plastic shell is placed on the turntable, the pressing block is screwed on the turntable, and then the plastic shell is tightened. The motor A drives the turntable to rotate so that the edge of the plastic shell fits the grinding wheel for edge grinding. The grinding wheel is arc-shaped. By adding different numbers of gaskets, the height of the edge of the plastic shell is adjusted, and then the grinding angle is adjusted to achieve a suitable edge grinding effect.

[0010] In a specific embodiment, the slide frame includes a slide rail and a slider, the slide rail is arranged on the workbench, and the slider is slidably connected to the slide rail.

[0011] In a specific embodiment, a cantilever is installed on the sliding block, and a curved guide rail is fixedly connected to the front end of the cantilever, and the grinding plate slides on the guide rail.

[0012] In the above implementation process, the cantilever slides on the slide rail through the slider, and the cantilever is pulled by the gravity pulling member, so that the grinding plate on the guide rail can be close to or away from the edge of the plastic shell.

[0013] In a specific embodiment, the vibration member includes a flat sleeve and a motor B, wherein the flat sleeve is fixed on the grinding plate, the motor B is arranged on the cantilever, an eccentric rod is connected to the output end of the motor B, and the eccentric end of the eccentric rod rotates in the flat sleeve.

[0014] In the above implementation process, the motor B drives the eccentric rod to rotate, and the eccentric end of the eccentric rod rotates in the flat sleeve, thereby realizing the reciprocating motion of the flat sleeve, and then driving the grinding plate to reciprocate in the arc guide rail, with a simple structure and low cost.

[0016] In a specific embodiment, a counterweight is movably placed on the tray.

[0017] In the above implementation process, a designated counterweight is placed on a pallet to generate a designated pulling force. The sliding and turning of the cable on the pulley block pulls the slider and the grinding disc on its upper portion close to the edge of the plastic shell. As the edge of the shell rises and falls, the same fitting force is maintained to ensure the same degree of grinding.

[0018] Compared with the prior art, the beneficial effects of the present application are: the turntable drives the plastic shell to rotate, and the traction part uses gravity to pull the slide, keeping the grinding disc close to the edge of the plastic shell and maintaining the same thrust as the edge rises and falls, ensuring consistent grinding effect, which is beneficial to improving the overall grinding effect.

The rotating frame 20 drives the plastic shell to rotate, and the traction member 60 uses gravity to pull the slide 30, so as to keep the grinding sheet 40 attached to the edge of the plastic shell, and maintain the same thrust as the edge rises and falls, so as to ensure a consistent grinding effect, which is conducive to improving the overall grinding effect.

[0026] See also Figure 1-Figure 2 The rotating frame 20 includes a rotating disk 21 and a motor A22. The motor A22 is mounted on the lower wall of the workbench 10. The rotating disk 21 is rotatably connected to the workbench 10, and the rotating disk 21 is connected to the output shaft of the motor A22. A pressing block 23 is screwed on the rotating disk 21, and a gasket 24 is arranged on the rotating disk 21. The plastic shell is placed on the rotating disk 21, and the pressing block 23 is screwed on the rotating disk 21, and then the plastic shell is tightened. The motor A22 drives the rotating disk 21 to rotate, so that the edge of the plastic shell fits the grinding disc 40 for edge grinding. The grinding disc 40 is arc-shaped. By adding different numbers of gaskets 24, the height of the edge of the plastic shell is adjusted, and then the grinding angle is adjusted, so as to achieve a suitable edge grinding effect.

[0027] See also Figure 1-Figure 3The slide 30 includes a slide rail 31 and a slider 32. The slide rail 31 is arranged on the workbench 10, and the slider 32 is slidably connected to the slide rail 31. A cantilever 33 is installed on the slider 32, and an arc-shaped guide rail 34 is fixedly connected to the front end of the cantilever 33, and the grinding sheet 40 slides on the guide rail 34. The cantilever 33 slides on the slide rail 31 through the slider 32, and the cantilever 33 is pulled by the gravity pulling member 60, so that the grinding sheet 40 on the guide rail 34 can be close to or away from the edge of the plastic shell.

[0028] See also Figure 1-Figure 3 The vibration member 50 includes a flat sleeve 51 and a motor B52. The flat sleeve 51 is fixed on the grinding disc 40. The motor B52 is arranged on the cantilever 33. The output end of the motor B52 is connected to an eccentric rod 53. The eccentric end of the eccentric rod 53 rotates in the flat sleeve 51. The motor B52 drives the eccentric rod 53 to rotate, and the eccentric end of the eccentric rod 53 rotates in the flat sleeve 51, thereby realizing the reciprocating motion of the flat sleeve 51, and then driving the grinding disc 40 to reciprocate in the arc guide rail 34. The structure is simple and the cost is low.

[0029] See also Figure 1-Figure 2 The traction member 60 includes a pulley block 61, a cable 62 and a tray 63. The two ends of the cable 62 are fixedly connected to the slider 32 and the tray 63 respectively, and the cable 62 is wound around the pulley block 61. A counterweight block 64 is movably placed on the tray 63. The designated counterweight block 64 is placed on the tray 63 to generate a designated pulling force. Through the sliding and turning of the cable 62 on the pulley block 61, the slider 32 and the grinding sheet 40 on the upper part are pulled close to the edge of the plastic shell. With the ups and downs of the edge of the shell, the same adhesion force is maintained to ensure the same grinding degree.

[0030] The working principle of the plastic shell processing and edging device is as follows: the plastic shell is placed on the turntable 21, the pressing block 23 is screwed on the turntable 21, and then the plastic shell is tightened, and a specified counterweight block 64 is placed on the tray 63 to generate a specified pulling force, and the sliding and turning of the cable 62 on the pulley group 61 pulls the slider 32 and the grinding disc 40 on the upper part to fit the edge of the plastic shell, and the motor A22 drives the turntable 21 to rotate, so that the edge of the plastic shell fits the grinding disc 40 for edge grinding. The grinding disc 40 is arc-shaped. By adding different numbers of gaskets 24, the height of the edge of the plastic shell is adjusted, and then the grinding angle is adjusted, so as to achieve a suitable edge grinding effect. 40 fits the edge of the plastic shell under the traction of gravity, and maintains the same fitting force as the edge rises and falls, ensuring the same degree of grinding. On the other hand, the motor B52 drives the eccentric rod 53 to rotate, and the eccentric end of the eccentric rod 53 rotates in the flat sleeve 51, thereby realizing the reciprocating motion of the flat sleeve 51, and then drives the grinding disc 40 to reciprocate in the arc guide rail 34, thereby keeping the grinding angle unchanged. In summary, the rotating frame 20 drives the plastic shell to rotate, and the traction member 60 uses gravity to pull the slide 30, keeping the grinding disc 40 fit to the edge of the plastic shell, and maintaining the same thrust as the edge rises and falls, ensuring consistent grinding effect, which is beneficial to improving the overall grinding effect.
