Description
Technical field
The pumped vacuum systems that the present invention relates to a kind of screen cloth Integratively shaping dies and consist of, the pumped vacuum systems that relates in particular to a kind of polyurethane fine screen mesh particular manufacturing craft and consist of.
Background technology
The relative metallic sieve of polyurethane fine screen mesh has following superiority: 1, high-wearing feature, be several times to tens times of metallic sieve the service life that facts have proved polyurethane fine screen mesh.2, self-cleaning property is high, is difficult for plug-hole, because polyurethane fine screen mesh has high resiliency, has effectively avoided the adhesion of moist particle, has guaranteed that screen(ing) machine can not block sieve aperture yet when the particle of screening dimension limit.3, lightweight, dynamic load is little, and the screen(ing) machine power consumption is little, has increased treating capacity, has improved production efficiency, has also reduced the operating noise of screen(ing) machine, has improved workman's working environment.
Present domestic polyurethane fine screen mesh can adopt following several manufacture usually:
1, spliced screen cloth: adopt screen cloth face, the crochet of polylith band edge to splice, adopt bonding agent to carry out bonding during splicing, although manufacturing process is comparatively simple, cost is lower, shortcoming is that the overall performance of screen cloth is bad, and the intensity of abutting edge is relatively poor, compare with integrally formed screen cloth, do not have the reinforced-core of perforation, the impact that intensity and life-span are subject to is larger, the reason that exists owing to abutting edge frame area simultaneously, its percent opening is affected, and it decreases.Because whole screen cloth face is not provided with reinforced-core and the bar shaped flow guide bar of perforation, and the strain of polyurethane material is larger, screen cloth pulling force when installing and using is larger, and whole screen cloth face can not sustain the due pulling force of fixed grit, and its intensity and life-span can be affected widely.
2, polyurethane punching screen cloth: adopt at the polyurethane flat-form material and make screen cloth with the way of laser beam drilling, its shortcoming is that percent opening is low, the shortcomings such as the compass screen surface hole of opening and the sieve end are measure-alike, easily stop up sieve aperture during use, and it has, and percent opening is low, processing capacity large, cost is higher.
Chinese patent CN101254655 discloses a kind of fiber reinforcement polyurethane fine screen mesh forming mold.Mould is comprised of upper and lower template, and cope match-plate pattern is designed with locating hole, reinforcement groove, fiber briquetting locating slot and a plurality of cast gate.Lower bolster is comprised of core rod, mould bases, fleece-laying piece and fiber briquetting.Core rod is formed by the module combinations of 1～2000 same size, and the core rod upper surface is the rectangle of 30mm～2000mm.Each module upper surface is the square of 30mm * 30mm～500mm * 500mm, at porose dividing strip runner of module upper surface design, segmentation parting bead runner and coarse segmentation bar runner, is the essential elements of moulding fine screen mesh.Use this mould to adopt injection molding method to make fabric reinforced polyurethane fine sieve, can be because the viscosity of the interior solution of system be excessive, can not be full of elongated and complicated runner or die cavity, defective is shorted in generation, thereby affected quality and the yield rate of fabric reinforced polyurethane fine sieve finished product, and product shaping is difficult.
In present screen cloth manufacturing technology, the defectives such as mesh structure is insecure, manufacturing process is complicated, the screen cloth serviceability is poor that it mainly exists.Because the screen size of screen cloth is less, heart yearn is thinner, traditional moulds and technique are difficult to realize its manufacturing, therefore traditional screen cloth all is to be divided into multistep to implement, can not the disposable integral manufacturing, and its percent defective is often higher.
