Embodiment Construction

[0024] Please refer to figure 1 , The fiber pretreatment device according to one embodiment of the present invention includes a chamber body 10 , a screw mechanism 20 , a crimping mechanism 30 , a retaining plate 40 and a first power source 50 .

[0025] The cavity 10 is provided with a cavity 100, and the cavity 10 has a feed port 11 for the fiber raw materials used in papermaking to enter and a discharge valve 12 for the fibers to flow out. The discharge valve 12 is set with a predetermined pressure value. When the cavity When the pressure in the chamber 100 is greater than the predetermined pressure value, the discharge valve 12 is opened to allow the fibers to discharge.

[0026] The screw mechanism 20 is disposed in the chamber 100 and adjacent to the feeding port 11 , and is used to push the fiber entering from the feeding port 11 into the chamber 100 .

[0027] The crimping mechanism 30 is disposed in the chamber 100 and rubs, squeezes, and crimps the fiber propelled b...

Abstract

A fiber processing device comprises a cavity body, a screw mechanism, a crimp mechanism, a material blocking plate and a power source. The cavity body is provided with a feed port for fiber entering and a discharge calve for discharging the fiber, and a preset pressure value is set on the discharge valve. When the pressure inside the cavity body is larger than the preset pressure value, the discharge valve is opened to discharge the fiber. The screw mechanism is used for pushing the fiber entered from the feed port into a chamber. The crimp mechanism is used for kneading and squeezing the fiber pushed by the screw mechanism to produce crimps. The material blocking plate is used for blocking curved fiber so as to enable the pressure in the chamber to rise. The power source is used for providing motive power needed by the screw mechanism and the crimp mechanism. After the fiber is preprocessed by the fiber processing device, the structural properties of natural fiber can be effectively changed, and bulk and water absorption capability of paper products made of the fiber are greatly improved.

Description

technical field [0001] The invention relates to a fiber pretreatment device, in particular to a pretreatment device for crimping fibers used as papermaking raw materials. Background technique [0002] In recent decades, my country's economic level has developed by leaps and bounds, and the people's demand for tissue paper is not only increasing, but also increasing. At present, the growth rate of my country's demand for household paper is much higher than the world average level, which poses a huge pressure on the protection and rational use of resources. If it is not handled properly, it will not only fail to effectively meet social needs, but will also cause great damage to natural resources. [0003] Rational use of natural resources and improvement of paper production technology have always been important research topics worldwide. At present, domestic and foreign researches on how to improve the characteristics of natural fibers, meet the basic needs of consumers, red...
