Problems solved by technology

At present, the microporous setters used in domestic production are made of ordinary ceramic materials, and the backward plastic production process is adopted. The processing is rough, the product shrinks greatly, and the deformation is serious; the holes are made by piercing with steel needles, and the holes are round. The flatness is very poor; the wear resistance of the material is poor, and the micropores of the thread collector after wear and tear increase and lose their roundness, which not only makes it difficult to remove knots on the thread, but also causes damage to the thread

Embodiment

[0018] Raw material preparation: refer to Table 1, which is the component distribution ratio raw material of the zirconia ceramic material for the preparation of the silk reeling device provided in this embodiment. According to the component distribution ratio (mass ratio) of Table 1, add an organic binder with a mass ratio of 5% to 15% of raw materials, such as polystyrene, diethyl phthalate and stearic acid, etc., and mix them uniformly to prepare Plastic sample 1, sample 2 and sample 3. Among them, Al 2 o 3 The average particle size is 0.2-2 μm.

[0019] Table 1

[0020]

[0021] Molding: The prepared plastic samples 1 to 3 are injection molded on the injection molding machine respectively to prepare the plain body of the silk reeling device, and the plain body is punched on the fixture by an ultrasonic punching machine. Adjust the current of the punching machine to 50-30 mA, keep the stage rising slowly and at a constant speed, use diamond abrasives with a particle ...

Abstract

The invention discloses a zirconia filament guide button for silk reeling and a method for preparing the same. The characteristics of a zirconia material of high strength, wearing resistance and self lubrication are utilized, and the injection forming process is adopted; micro pores of which the diameters are between 0.16 and 0.30mm are prefabricated on a biscuit by an ultrasonic puncher; and the biscuit is sintered and formed at a temperature of 1,600 DEG C, and punched with through holes by the ultrasonic puncher so as to prepare the zirconia filament guide button for silk reeling. The technical proposal effectively solves the problem of punching micro pores on ceramics and realizes low cost in punching micro pores on ceramics. Compared with the common ceramic filament guide button, the wear resistance of the zirconia filament guide button is improved by more than ten times, the micro pores are round and uniform, the yarns are smooth, and the grade of raw silk is one grade improved.

Description

technical field [0001] The invention relates to a silk reeling device and a preparation method thereof, in particular to a silk reeling device made of zirconia ceramic material. Background technique [0002] The microporous threader is an important part of the silk reeling machine, which plays the roles of gathering cocoon threads, fixing the sheath position, reducing moisture, blocking knots, enhancing cohesion, and increasing tensile force. The microporous setter has a great influence on the quality of silk during the silk reeling process. At present, the microporous setters used in domestic production are made of ordinary ceramic materials, and the backward plastic production process is adopted. The processing is rough, the product shrinks greatly, and the deformation is serious; the holes are made by piercing with steel needles, and the holes are round. The flatness is very poor; the wear resistance of the material is poor, and the micropores of the thread collector aft...
