Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric raw material preparation, in particular to a modification device for non-woven fabric production. Background Art

[0002] Non-woven fabric is a kind of non-woven fabric. It is a non-woven fabric formed by directly using polymer chips, short fibers or filaments to form a net through airflow or machinery, and then through water spunlace, needle punching, or hot rolling reinforcement, and finally after finishing. Non-woven fabrics are made of polyester, polypropylene, nylon, spandex, acrylic, etc. according to their composition. The modification of non-woven fabrics is mainly for the modification of chemical fiber raw materials such as polyester, polypropylene, nylon, etc.

[0003] The modification of chemical fiber raw materials is the process of adding one or more other substances to the plastic resin to change its original properties and expand its scope of application. It is specifically achieved by blending using a mixer, and the corresponding modified materials are added according to different modification requirements.

[0004] At present, plastic mixers mix raw materials evenly by stirring. During the stirring process, plastic particles rub against each other, which will generate a lot of static electricity. The static electricity is released in the form of sparks, which will ignite the scattered raw material powder during the stirring process. Under the action of static electricity adsorption, the scattered raw material powder will adhere to the mixer and is difficult to clean.

[0005] In order to reduce the impact of static electricity, a vertical spreading mixer is used to mix only plastic particles. During mixing, the mixing is carried out in a spreading manner, and the friction of the plastic particles is small. At the same time, an antistatic agent is added when the plastic particles are stirred, but the vertical spreading mixer only reduces the degree of friction of the material, and static electricity will still be generated by friction. Although the addition of the antistatic agent makes the plastic have an antistatic effect, other properties of the plastic may also be affected. Utility Model Content

[0034] Furthermore, the blades of the auger 3 extend to above the top of the lifting pipe 2, and the centrifugal force of the blades of the auger 3 when rotating is utilized to fully scatter the material.

[0035] In this way, the non-woven fabric raw material particles and the modified raw material are put into the hopper 13, the raw materials enter the lifting tube 2 through the feed port at the bottom of the lifting tube 2, and are lifted to the top of the lifting tube 2 by the auger 3. Under the action of the rotating centrifugal force of the auger 3, the materials are thrown into the mixing tank 1 for mixing, and the materials inside the mixing tank 1 flow back to the hopper 13 through the return pipe 11, and then lifted and thrown into the mixing tank 1 by the auger 3. The materials are circulated, lifted and thrown to fully mix the non-woven fabric raw material particles and the modified raw material.

[0036] Although the vertical spreading mixer can reduce the degree of material friction, it will still generate static electricity during the material circulation and lifting process. If antistatic agents are added to the material, although the plastic can have an antistatic effect, other properties of the plastic may also be affected.
