Description

Technical Field

[0001] This utility model relates to plastic processing, and in particular to a device for polishing and removing the printed layer of optical discs. Background Technology

[0002] The demand for high-quality plastic raw material granules remains strong across a wide range of industries, including footwear, daily-use plastic products, and packaging materials. As a fundamental processing raw material, the performance of these granules directly determines the quality of the final product. Traditional virgin plastic pellets are relatively expensive; therefore, recycling post-consumer plastics into standard-compliant recycled plastic pellets has become a crucial way for the industry to reduce costs, increase efficiency, and achieve sustainable development. Currently, the raw material sources for recycled plastic pellets are diverse, including various optical waste media such as plastic optical discs (CDs / VCDs / DVDs). These media are typically made from high-purity engineering plastics such as polycarbonate (PC) or polypropylene (PP) and have extremely high recycling value. However, to transform these regularly sized, hard solid plastics into uniform pellets suitable for injection molding or extrusion, a critical pretreatment process—grinding—is essential. Mechanical grinding reduces their size to easily meltable, granulated flakes, a prerequisite for efficient melting, homogenized extrusion, and ultimately, the production of high-quality recycled plastic pellets.

[0003] Before traditional CD recycling, the printed layer on its surface needs to be removed. This usually requires manual removal, which results in poor polishing effect, low efficiency, and high labor intensity. Utility Model Content

[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 the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] Please see Figure 1-5 This utility model provides a technical solution for a device for polishing and removing the printing layer of an optical disc: A device for polishing and removing the printing layer of an optical disc includes a conveying mechanism 1, on which several sets of polishing boxes 2 are sequentially and spaced apart, and each set of polishing boxes 2 is fixedly connected to a mounting plate 3. Two sets of first polishing mechanisms 4 are symmetrically installed on the mounting plate 3. Several sets of second polishing mechanisms 5 are arranged at intervals inside the polishing boxes 2 on the conveying mechanism 1. A spraying mechanism 6 is installed on one side of the several sets of polishing boxes 2. A feeding mechanism 7 is installed at the feeding end of the conveying mechanism 1.

[0027] In this embodiment, a conveying mechanism 1 is provided to transport optical discs to be polished into the polishing box 2. A first polishing mechanism 4 is provided to polish and remove the printing layer of the optical discs transported by the conveying mechanism 1. By providing multiple sets of first polishing mechanisms 4, the printing layer of the optical discs can be polished multiple times to improve the polishing effect. A second polishing mechanism 5 is provided to cooperate with the first polishing mechanism 4 to further polish and remove the printing layer of the optical discs, thereby improving the polishing effect. A spraying mechanism 6 is provided to spray water to clean the optical discs on the conveying mechanism 1, which facilitates the cleaning of surface coating residues while polishing the optical discs. A feeding mechanism 7 is provided to feed the stacked optical discs into the polishing box 2 in sequence along with the conveying mechanism 1. All electrical components of the equipment are controlled by an external controller to ensure normal operation of the equipment.

[0028] Furthermore, the conveying mechanism 1 includes a workbench 11, with an active conveying roller 12 and a passive conveying roller 13 rotatably connected to both ends of the workbench 11 via bearings.

A conveying motor 15 is installed on one side of the workbench 11 located on the active conveying roller 12. The output end of the conveying motor 15 is drivenly connected to the active conveying roller 12 via a belt.

[0029] In this embodiment, a conveying mechanism 1 is provided to convey the optical disc to be polished into the polishing box 2. The conveying mechanism 1 includes a worktable 1, and an active conveying roller 12 and a passive conveying roller 13 are rotatably connected at both ends of the worktable 1 via bearings. A conveyor belt 14 is fitted on the active conveying roller 12 and the passive conveying roller 13. Driven by the conveying motor 15, the active conveying roller 12 is rotated by the belt, thereby driving the conveyor belt 14 to drive the transmission. The surface of the conveyor belt 14 is patterned, which can increase the friction of the optical disc on the conveyor belt 14 and improve its polishing effect.

[0030] Typically, the first grinding mechanism 4 includes: a grinding frame 41, which is fixedly connected to the mounting plate 3. The upper and lower ends of the grinding frame 41 are rotatably connected to an active grinding shaft 42 and a passive grinding shaft 43 via bearings.

[0031] In this embodiment, a first polishing mechanism 4 is provided to polish and remove the printed layer of the optical disc conveyed by the conveying mechanism 1. The first polishing mechanism 4 includes a polishing frame 41, which is vertically fixed on the mounting plate 3. The frame 41 is driven by a drive motor 45 to rotate, which in turn drives the active polishing shaft 42 via a belt, thereby driving the polishing sand belt 44 to rotate on the active polishing shaft 42 and the passive polishing shaft 43. The surface of the polishing sand belt 44 is a frosted layer, and there is a gap between the bottom of the polishing sand belt 44 and the conveyor belt 14, so that the conveyor belt 14 can pass through the gap and polish and remove the printed layer on the surface of the optical disc through the polishing sand belt 44.

[0032] Specifically, the second grinding mechanism 5 includes a fixed sleeve 51, and two sets of fixed sleeves 51 are provided. The two sets of fixed sleeves 51 are symmetrically installed on both sides of the worktable 11 located on the conveyor belt 14. A bearing column 52 is installed on the fixed sleeve 51, and a grinding roller 53 is installed on the two sets of bearing columns 52.

[0033] In this embodiment, a second polishing mechanism 5 is provided to polish and remove the printed layer of the optical disc conveyed by the conveying mechanism 1. The second polishing mechanism 5 includes a fixed sleeve 51, which is symmetrically installed on both sides of the worktable 11. Bearing columns 52 are fixedly connected to the two fixed sleeves 51. The two ends of the polishing roller 53 are installed on the bearing columns 52, which are mounted above the conveyor belt 14 and have a gap with the conveyor belt 14 to facilitate the passage of the optical disc while polishing and removing the printed layer of the optical disc.

[0034] In addition, the spraying mechanism 6 includes a water inlet pipe 61, which is fixedly connected to the same side of several grinding boxes 2 by several sets of water pipe fixing clamps 62. Several sets of spray pipes 63 are fixedly connected to the water inlet pipe 61 in sequence. The number of spray pipes 63 corresponds to the number of grinding boxes 2, and the spray pipes 63 extend into the interior of the grinding box 2 in sequence. Several sets of spray holes are opened at the bottom of each spray pipe 63.

[0035] In this embodiment, a spraying mechanism 6 is provided to spray water to clean the optical discs on the conveyor mechanism 1, which facilitates cleaning the surface coating residue of the optical discs while polishing them. The spraying mechanism 6 includes a water inlet pipe 61, which is connected to an external water inlet device to supply water to the water inlet pipe 61. The water inlet pipe 61 is horizontally installed on the back side of several sets of polishing boxes 2 in sequence by fixing clamps 61. A spray pipe 63 is fixedly connected to the water inlet pipe 61. The spray pipe 63 extends into the interior of the polishing box 2 in sequence, which facilitates the spray holes at the bottom of the spray pipe 63 to spray water to clean the optical discs on the lower conveyor belt 14.

[0036] In addition, the feeding mechanism 7 includes a feeding fixing plate 71, which is provided in two sets. The two sets of feeding fixing plates 71 are symmetrically installed on both sides of the workbench 11 located on the conveyor belt 14. The two sets of horizontal plates 72 are fixedly connected to each other. The two sets of feeding arc plates 73 are symmetrically installed on the horizontal plates 72. There is a gap between the feeding arc plates 73 and the conveyor belt 14.

[0037] In this embodiment, a feeding mechanism 7 is provided to sequentially feed stacked optical discs into the polishing box 2 along with the conveyor mechanism 1. The feeding mechanism 7 includes a feeding fixing plate 71, which is fixed horizontally on the fixing plate 71 by two horizontal plates 72. During feeding, the optical discs are stacked on two feeding arc plates 73, where there is a gap between the feeding arc plates 73 and the conveyor belt 14. When the conveyor belt 14 moves, the optical discs sequentially enter the polishing box 2 under the action of friction and gravity, thus realizing sequential feeding.

[0038] It should be noted that the grinding roller 53 is located above the conveyor belt 14, and there is a gap between the two.

[0039] In this embodiment, a gap exists between the polishing roller 53 and the conveyor belt 14 to facilitate the passage of the optical disc while the polishing roller 53 polishes and removes the printed layer of the optical disc. The height of this gap is adapted to the thickness of the optical disc.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
