Drum paper carcass forming device

Abstract

The invention discloses a drum paper carcass forming device which is characterized by comprising a filter, a high-pressure grouting device and a lifting mechanism, wherein the filter comprises a filter part, a carcass forming groove and a plurality of filter holes communicated with the carcass forming groove are formed in the filter part, and the hole diameter of each filter hole is smaller than or equal to 26 microns; the high-pressure grouting device is provided with a grout outlet, and the grout outlet faces the carcass forming groove; and the lifting mechanism is connected with the high-pressure grouting device. The drum paper carcass forming device disclosed by the invention can greatly reduce the waste of water and slurry, and the manufactured drum paper carcass has relatively bettertoughness and rigidity.

Description

technical field [0001] The invention relates to the technical field of horn production, in particular to a drum paper carcass forming device. Background technique [0002] Drum paper is the main sound-generating part of the speaker. The quality of the sound quality of the speaker has a lot to do with the drum paper. In addition to providing better output power and audio characteristics of the speaker and speaker, it is also a key factor in the manufacture of speakers and speakers. Speakers are the basis of quality control, and can effectively prolong the service life of speakers and speakers. [0003] With the continuous development of science and technology, speakers have been widely used in TVs, computers, automobiles, mobile phones and other equipment. Drum paper is the main sound-generating part of speakers, and the quality of drum paper has a great influence on the quality of speaker sound. [0004] Drum paper generally includes a cone body and a ring-shaped overhang c...

AI Technical Summary

Problems solved by technology

[0006] 1. Because the filter holes of the filter screen are relatively large, the surface of the formed drum paper carcass is relatively rough;

[0007] 2. Because the negative pressure is generated in the water hole of the forming mold through grouting, the drum paper carcass production material in the slurry is tightly adsorbed on the forming filter to form the drum paper carcass, so the water content in the slurry needs to be greatly increased The content of the pulp used to make the carcass of drum paper will generate more waste water, resulting in a relatively high waste of water

[0008] 3. The pore diameter of the forming filter is 0.26mm-0.433mm, which is relatively large, which will cause many fine wood fibers to pass through the forming filter and the water holes of the forming mold, resulting in a loss of more than 30% of the slurry

[0010] 5. Due to the relatively large pore size of the filter holes of the forming filter, the surface of the formed drum paper carcass is rough and not smooth, which reduces the aesthetics of the drum paper carcass
