Problems solved by technology
In the manufacturing process of polyester capacitors, a polyester capacitor winding machine is required. The center of the polyester capacitor winding machine is equipped with a needle cylinder that provides metal foil or metal needles. Usually, the needle cylinder is fixed on the polyester capacitor with screws. In the center of the winding machine, because the polyester capacitor winding machine will vibrate during the working process, the screws will also loosen from the screw holes with the vibration, making the fixing of the needle cylinder unstable, which will affect the manufacturing accuracy of the polyester capacitor , leading to an increase in the scrap rate of polyester capacitors. In order to fix them, workers need to manually tighten them, which reduces work efficiency

The invention provides a central part needle cylinder fixing device of a polyester capacitor winding machine, wherein the central part needle cylinder fixing device comprises a bolt and a nut, wherein the bolt penetrates through a rack of the winding machine and a needle cylinder main body; the nut is screwed to the bolt and is used for fixing the rack of the winding machine and the needle cylinder main body; the nut is provided with at least one splicing groove which penetrates through the outer side wall and inner side wall of the nut; and the splicing groove is internally provided with a splicing sheet which is spliced with a thread on the bolt. The needle cylinder can be firmly fixed on the polyester capacitor winding machine, and has less possibility of dropping off; the influence on the manufacturing accuracy of a polyester capacitor is avoided; the rejection rate of the polyester capacitor is reduced; and the working efficiency is improved.
Description
technical field [0001] The invention relates to the field of polyester capacitor processing, in particular to a central syringe fixing device of a polyester capacitor winding machine. Background technique [0002] Polyester capacitors have a high dielectric constant, small size, large capacity, and good stability. They are suitable as bypass capacitors and used in various DC or low-to-medium frequency dynamic circuits. The accuracy, loss angle, insulation resistance, temperature characteristics, reliability and environmental adaptation of polyester capacitors are better than those of electrolytic capacitors and ceramic capacitors. Polyester capacitors use two pieces of metal foil as electrodes, sandwiched in a very thin insulating medium, rolled into a cylindrical or flat cylindrical core, and the medium is polyester. In the manufacturing process of polyester capacitors, a polyester capacitor winding machine is required. The center of the polyester capacitor winding machine...
