Description

Technical Field

[0001] The utility model specifically relates to the technical field of burr trimming of plastic products, in particular to a burr trimming device for processing plastic products. Background Art

[0002] Plastic products are made of plastics, polymer compounds formed by addition polymerization or condensation polymerization, commonly known as plastics or resins. The composition and shape can be freely changed. It is composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. In the production process or for the convenience of transportation or storage, plastic products are generally produced or cut according to the specified size, which will cause more burrs on the edges of plastic products, so the burrs need to be removed.

[0003] The traditional method for repairing the burrs of plastic products is manual repair. With the continuous advancement of science and technology, some auxiliary burr repair devices have gradually emerged. The burr repair device clamps and fixes the plastic product, and then uses a tool to repair the plastic product. However, the traditional burr repair device can only clamp and fix plastic products of a single shape. It is difficult to clamp and fix some plastic products with special-shaped structures, which is very inconvenient to use.

[0004] After searching, Chinese patent publication number CN202023009264.3 discloses a device for quickly repairing burrs of plastic products; it includes a workbench and a trimming knife, the workbench is provided with a fixed box, a fixed cylinder is rotatably installed in the fixed box through a bearing, an air bag is embedded in the inner cavity of the fixed cylinder, an air nozzle connected to the air bag is provided at one end of the fixed cylinder, a driving motor is also provided on the workbench, and the output end of the driving motor is connected to the fixed cylinder; a through hole is opened on the workbench on one side of the fixed box, a shell is provided on the workbench below the through hole, and the shell is provided inside Support platforms are provided on both sides of the bottom of the wall, and filters slidably inserted into the shell are provided on the support platforms, and a filter box is also provided under the workbench; when the structure in the above patent fixes the plastic product, it is fixed in the fixed cylinder through the air bag, so when trimming, the pruning knife needs to penetrate the burr when trimming the burr of the plastic product, so the sharp pruning knife will contact the surface of the air bag, which will cause the air bag to be damaged, resulting in the effect that the plastic product and the fixed cylinder cannot be effectively fixed, so when trimming, it is necessary to trim by pure manual labor, and the work efficiency is low.

[0005] In view of the above situation, we provide a burr trimming device for processing plastic products. The plastic product is placed on a turntable, and the product is fixed by the clamps on both sides of the turntable. The turntable is driven by a driving motor to rotate, so that the burr on the edge of the product is rotated under the trimming knife. The trimming knife is driven up and down by an electric push cylinder to contact the burr. The rotation of the turntable and the movement of the slide plate and the crossbeam can effectively trim and cut along the edge of the product. The trimmed burr is collected into the collection box through the negative pressure pipe inside the collection cover, so that the burr is centrally processed. Utility Model Content
