Description

Technical Field

[0001] The utility model belongs to the field of papermaking equipment, in particular to a pulping machine for electrolytic capacitor paper raw materials. Background Art

[0002] Electrolytic capacitor paper is a special paper, usually used in the production of electrolytic capacitors. In the production of electrolytic capacitor paper, the main function of the pulping machine is to crush and grind the raw materials to release the fine fibers and fillers in the fiber raw materials. This process can improve the smoothness and uniformity of the electrolytic capacitor paper, thereby affecting the performance and reliability of the capacitor. Through the crushing and grinding of the pulping machine, the fiber raw materials can be further processed into finer fibers, increasing the fineness and uniformity of the pulp, which is beneficial to improving the quality of the electrolytic capacitor paper. The existing pulping machine feeds through the feeding hopper to destroy the bridging phenomenon of the materials in the feeding hopper to ensure smooth feeding. Chinese patent CN219364167U discloses a high-concentration pulping machine, which uses a telescopic rod to push the pusher to swing back and forth in the feeding hopper, so that the pusher intermittently pushes the materials in the feeding hopper to break up the accumulation of materials. However, the device needs to push the material return piece back and forth, and the decrease in the feeding speed causes the pulping efficiency of the pulping machine to decrease.

[0005] In the present technical scheme, the material entering the refiner body is put into the feed hopper, and is crushed by the crushing roller in the crushing structure. The material is broken into smaller particles and powder and enters the feeding pipe below. The material is pushed into the grinding disc of the refiner body by the spiral feeding device arranged in the feeding pipe. At the same time, in order to avoid blockage and bridging of the crushed material between the feed hopper and the feeding pipe, an anti-blocking structure is arranged, and the working block is driven to rotate by the first rotating shaft to ensure that the material crushed by the crushing roller smoothly enters the feeding pipe below from the feed hopper. At the same time, the setting of the crushing roller can, on the one hand, crush the material to reduce the volume of the material to avoid blockage of the material in the feed hopper, and make it easier to transport the material.
