Drum paper carcass forming device

Abstract

The invention discloses a drum paper carcass forming device. The drum paper carcass forming device comprises a forming mechanism and a forming mechanism, wherein the forming mechanism is used for receiving fiber pulp and forming the fiber pulp into an initial pressing piece; the coloring mechanism is arranged on one side of the forming mechanism and used for containing coloring liquid; the shifting mechanism comprises a shifting driving part and a mechanical arm installed on the shifting driving part, and the mechanical arm is driven by the shifting driving part to move so as to move the primary pressing piece into the coloring mechanism to be colored and then move the colored primary pressing piece; and the pressing mechanism is used for receiving the colored primary pressing piece and pressing and forming the colored primary pressing piece. According to the drum paper carcass forming device, the drum paper carcass is dyed after being formed, no chemical component is added into the pigment, and the pigment is not in direct contact with the environment, so that the drum paper carcass forming device is environment-friendly, and the water treatment cost is greatly saved.

Description

technical field [0001] The invention belongs to the technical field of trumpet product preparation devices, and in particular relates 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] At present, the method for preparing the drum paper carcass is similar. Generally, the paper material is first soaked and crushed to form a fiber slurry, then the fiber slurry is dyed, and then the moisture of the fiber slurry is drained, and then placed until the fiber slurry is dry. This method has the following disadvantages: when dyeing, it ...

Problems solved by technology

[0003] At present, the method for preparing the drum paper carcass is similar. Generally, the paper material is first soaked and crushed to form a fiber slurry, then the fiber slurry is dyed, and then the moisture of the fiber slurry is drained, and then placed until the fiber slurry is dry. This method has the following disadvantages: when dyeing, it is necessary to add color-fixing chemical components. Since the color material can be better dyed under acidic conditions, the water leached from the fiber slurry is acidic. It contains a lot of pollutants, and the water itself contains pigments. 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 a lot of pressure on the environment.
