[0004] Lightweight: Plastic products are light in weight, making them convenient to carry and transport;

[0005] Corrosion-resistant: Plastic products have good acid and alkali resistance and corrosion resistance, and are suitable for various environments;

[0006] Good processing performance: Plastic raw materials can be processed into products of different shapes through various processes such as injection molding, extrusion, and blow molding;

[0007] Low cost: The production cost of plastic products is relatively low, making them suitable for large-scale production;

[0008] Good insulation performance: Plastic products have good electrical insulation performance and are widely used as insulation materials for electrical equipment and cables.

[0009] At present, after the semi-finished plastic products are demolded, due to the remaining temperature during demolding and the adhesion between the semi-finished products and the mold during demolding, pulling will occur during the demolding process, which will directly cause the surface of the semi-finished products to be uneven or have barbs. If the trimming treatment is not carried out, the unevenness of the surface will greatly affect the product quality after the finished product is processed and colored in the later stage.

Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0030] Referring to Figures 1 - 5 , a trimming device for plastic products, comprising a U-shaped frame 10, characterized in that: bearings 11 are penetrated through both sides of the U-shaped frame 10, and the connection position between the outer ring wall of the bearing 11 and the U-shaped frame 10 is fixed by welding. The inner ring wall of the bearing 11 is in interference fit with a shaft rod 12. A cutting disc 13 and a grinding disc 14 are respectively arranged at both ends of the shaft rod 12. A grinding sheet 15 is fixedly embedded in the end face of the grinding disc 14;

[0031] A motor 16 is arranged inside the U-shaped frame 10, and the outer wall surface of the motor 16 is fixedly installed on the inner side of the U-shaped frame 10 through a bracket. A rotating shaft for driving is arranged inside the motor 16, and a driving bevel gear 17 is fixed at the end of the rotating shaft. A linkage bevel gear 18 is fixedly sleeved on the surface of the shaft rod 12, and the linkage bevel gear 18 is meshed with the driving bevel gear 17.

[0032] Furthermore, it should be noted that a handle 20 is arranged at the tail of the U-shaped frame 10. The connection position between the handle 20 and the U-shaped frame 10 is fixed by screws. The surface of the handle 20 is coated with a polyurethane coating for anti-slip. The handle 20 can be held by hand, and at the same time, anti-slip protection is provided through the anti-slip polyurethane coating.

[0033] Furthermore, it should be noted that a protective cover 21 is fixedly sleeved on the surface of the handle 20. The protective cover 21 is in an umbrella shape and is made of a lightweight plastic material, which can avoid debris splashing and damaging the hand skin when cutting or grinding plastic products.

[0034] Further, it should be noted that the cutting disc 13 is slidably sleeved on one end of the shaft rod 12. A first limiting block 31 is fixed inside the cutting disc 13, and a first limiting groove 30 is provided at the end of the shaft rod 12. The first limiting block 31 is slidably arranged in the first limiting groove 30. When the cutting disc 13 and the shaft rod 12 are easy to install, it also ensures that while the shaft rod 12 rotates, the cutting disc 13 rotates.

[0035] Further, it should be noted that a first external thread is provided at the end of the shaft rod 12, and a first nut 32 is threadedly connected to the surface of the first external thread. The first nut 32 is closely arranged with the cutting disc 13. After the cutting disc 13 and the shaft rod 12 are sleeved, the two can be locked by the first nut 32 to ensure the safety of the cutting process.

[0036] Further, it should be noted that the grinding disc 14 is slidably sleeved on the other end of the shaft rod 12. A second limiting block 41 is fixed inside the grinding disc 14, and a second limiting groove 40 is provided at the end of the shaft rod 12. The second limiting block 41 is slidably arranged in the second limiting groove 40. When the grinding disc 14 and the shaft rod 12 are easy to install, it also ensures that while the shaft rod 12 rotates, the grinding disc 14 rotates.

[0037] Further, it should be noted that a second external thread is provided at the end of the shaft rod 12, and a second nut 42 is threadedly connected to the surface of the second external thread. The second nut 42 is closely arranged with the grinding disc 14. After the grinding disc 14 and the shaft rod 12 are sleeved, the two can be locked by the second nut 42 to ensure the safety of the cutting process.

[0038] Working mode: When trimming and processing plastic products, by connecting the power supply of the wire 16, the motor 16 can drive the driving bevel gear 17 to rotate through the rotating shaft. Through the meshing of the driving bevel gear 17 and the linkage bevel gear 18, the shaft rod 12 rotates, so as to drive the cutting disc 13 and the grinding disc 14 to rotate respectively. The cutting disc 13 can cut and trim the unevenness and burrs of the plastic products. The ground part of the plastic products can be smoothed by the grinding piece 15 on the grinding disc 14. The stable operation can be carried out by holding the handle 20, and the protective cover 21 can avoid the flying debris from hurting the hands during grinding or cutting.

[0039] When the cutting disc 13 needs to be replaced, turn the first nut 32 with pliers so that the first nut 32 can threadedly separate the end of the shaft rod 12 from the first external thread, so that the first limiting block 31 slides out of the first limiting groove 30, and the cutting disc 13 can be separated from the shaft rod 12.

[0040] When it is necessary to replace the grinding disc 14, turn the second nut 42 with a work clamp so that the second nut 42 can thread-separate the end of the shaft rod 12 from the first external thread, so that the second limiting block 41 slides out of the second limiting groove 40, and the grinding disc 14 can be separated from the shaft rod 12.

[0041] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
