Problems solved by technology

[0004] 1. It is necessary to add color-fixing chemical components during dyeing. Since the coloring material can be better dyed under acidic conditions, the water leached from the fiber slurry is acidic and contains many pollutants, and the water itself contains coloring material , the cost of post-treatment water is very high, and it cannot be guaranteed that the treated water can be directly reused, which wastes a lot of water resources, increases production costs, and puts great pressure on the environment.
[0005] 2. The degree of draining of the fiber slurry cannot be guaranteed to be the same in each batch, and it cannot be guaranteed to be in an absolute dry state. After adding water, the concentration of the fiber slurry in each batch is difficult to ensure consistent, resulting in the quality of the drum paper carcass produced in each batch. Different, it is difficult to meet the user's requirements; and in the process of taking out the fiber slurry, the fibers in the original water will be lost, which further increases the cost of raw materials; the wet fiber material may breed mold during the draining process, resulting in fiber material failure or product failure
[0006] 3. In the later stage, add the fiber slurry to the supply tank, add water and stir until it is taken evenly, take out the fiber slurry and filter it every time, after a period of time, the fiber slurry will become thinner, and the speed of taking the material needs to be adjusted, because The adjustment accuracy is limited, and the quality of the same batch of products will still be inconsistent, resulting in a significant drop in product yield

Embodiment 1

[0032] The drum paper carcass production method described in the embodiment of the present invention comprises the following steps:

[0033] S1, mixing the fiber material and water, and breaking the fiber material to form a fiber slurry;

[0034] S2. Quantitatively taking out the fiber slurry and molding it to form an initial pressed piece;

[0035] S3, immersing the initial pressing piece in the colorant liquid for a second preset time to form an initial pressing piece with colorant;

[0036] S4, extracting the moisture of the initial pressing part with coloring material to form a semi-finished product;

[0037] S5. Hot pressing the semi-finished product to form a primary product.

[0038] In one embodiment, step S1 specifically includes: mixing the fiber material and water according to a preset ratio, soaking the fiber material for a first preset time, and crushing the fiber material to form a fiber slurry. After soaking for a period of time and then smashing, the fiber m...

Embodiment 2

[0059] The embodiment of the present invention differs from the first embodiment in that it further includes the following step S6: dispersing the impregnating liquid onto the primary product to form a pre-product; removing moisture from the pre-product, heating and curing to obtain a finished product. The primary product is immersed in the immersion liquid and then solidified. The colloid in the immersion liquid adheres to the surface of the primary product, which can not only play a waterproof role, but also encapsulate the coloring material to ensure that the finished product will not fade.

[0060] In one embodiment, step S6 is specifically: placing the preliminary product on the mold, dispersing the immersion liquid from above the preliminary product onto the preliminary product, maintaining the third preset time to form the pre-finished product, and removing the moisture of the pre-finished product, Heating and curing to obtain finished products. Among them, the bottom o...

Abstract

The invention discloses a drum paper carcass production method. The drum paper carcass production method comprises the following steps: S1, mixing a fiber material with water, and crushing the fiber material to form fiber slurry; s2, the fiber slurry is quantitatively taken out and formed, and an initial pressing piece is formed; s3, the initial pressing piece is soaked in pigment liquid for second preset time, and the initial pressing piece with pigment is formed; s4, water of the initial pressing piece with the pigment is pumped out, and a semi-finished product is formed; and S5, the semi-finished product is subjected to hot press molding, and a primary finished product is formed. According to the drum paper carcass production method, materials can be continuously supplied, pigments and chemical agents do not need to be added, the drum paper carcass production method is environmentally friendly, the water treatment cost and the cost of water resources and fiber material resources are greatly saved, the concentration of fiber pulp in each batch is consistent, and the consistency and the yield of products are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of horn products, and in particular relates to a production method of a drum paper carcass. 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] At present, in the world, the method for preparing the drum paper carcass is similar. Generally, the fiber material (usually paper fiber) is soaked and broken to form a fiber slurry, and then the fiber slurry is dyed, and then the fiber slurry is drained. moisture, place it until the fiber slurry is dry, and then add water to take the material for molding. Th...
