the polyurethane bar screen mesh produced and used at present uses a steel wire rope to coat a polyurethane layer as a warp and weft wire, is woven at a certain temperature and process and is in a mesh shape by hot-melt welding, a specially-made metal tensioning hook is arranged at the edge part, a specially-made fixed bent iron and a tensioning bolt are used for tensioning on a screen machine wall plate when the polyurethane bar screen mesh is used, and the purposes of prolonging the service life and improving the wear resistance of the screen mesh are achieved by utilizing the rigidity and the strength of the steel wire rope and the high wear resistance of polyurethane. However, the bar screen with the polyurethane layer coated by the steel wire rope used at present has the following phenomena in the use process: because the cross section of the polyurethane bar screen is circular, the hole pattern is in a hyperbolic shape, the upper part of the upper half part of the hole pattern is large and the lower part of the hole pattern is small, and the steel wire rope used as the bar of the framework is not easy to deform in the vibration process, so that some granular materials with the size close to that of the sieve holes are clamped in the holes, the holes are not easy to pass through, the screening efficiency is influenced, and the screening effect is seriously influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming prior art not enough, providing a stifled hole polyurethane stick screen cloth is prevented to high resilience, have good high wear-resisting, high resilience, toughness is strong, from clearance, can effectively eliminate sifter plug hole phenomenon, improves the screening effect, reduces and maintains the degree of difficulty, improves work efficiency.
The utility model provides a stifled hole polyurethane stick screen cloth is prevented to high resilience comprises tight hook, connecting plate, bolt, round steel and polyurethane stick screen cloth, its characterized in that, polyurethane stick screen cloth uses steel wire rope core polyurethane to cover the glued stick strip and be reinforcement area, aramid cord core polyurethane cladding glued stick for the warp yarn, frameless polyurethane stick for the woof, forms through hot melt welding, the warp yarn of polyurethane stick screen cloth, woof cross section are the down-trapezoidal, make all sieve meshes all be the back taper, tighten with the bolt between the tight hook of limit portion tight hook of polyurethane stick screen cloth and the connecting plate, the steel wire rope core polyurethane of limit portion covers the glued stick strip and is reinforcement area for the woof to attach a round steel and strengthen.
The production process of the utility model: firstly, drawing wires with different materials of steel wire ropes, aramid ropes or frameless as core wires on an extruder to produce polyurethane coated bars according to requirements; the extrusion port is trapezoidal, namely the section of the polyurethane coated glue stick strip is trapezoidal; secondly, according to the pass demand hot melt welding silk screen joint, steel wire rope core polyurethane cladding stick sets up in tight hook installation department that rises, and the warp sets up to aramid fiber rope core polyurethane cladding glue stick, and the woof sets up to no skeleton polyurethane glue stick, and thirdly, tighten tight hook and fixed plate with the bolt to screen cloth edge portion, the round steel is placed in screen cloth edge portion tight hook and fixed plate centre that rises for increase the tight intensity that rises of screen cloth.
The utility model discloses a theory of operation: the utility model adopts the aramid cord polyurethane coating rubber rod strip as the warp yarn, fully utilizes the strength of the aramid fiber and the high wear resistance of the polyurethane high polymer elastomer, and ensures the strength and the service life of the screen mesh; the steel wire rope core polyurethane coating glue bar and the round steel are used for edge reinforcement, so that the edge strength can be effectively enhanced, and the firmness and reliability of installation are improved; the framework-free polyurethane rubber bars are adopted as the wefts, so that the pass of the screen is ensured to be neat, the size meets the requirement, and the polyurethane framework-free bars have elasticity, so that the materials can be bounced or pass through the screen through deformation under the vibration condition when entering the screen holes.
The utility model discloses an useful part: 1. the product has the advantages of wear resistance, high elasticity, strong toughness, strong screen mesh deformation capability and excellent self-cleaning effect, and is particularly suitable for grading materials with medium and fine particle sizes and irregular shapes; 2. the utility model is a great technical improvement to the prior bar screen, and ensures the expansion strength of the screen mesh by arranging the steel wire rope polyurethane coating rubber bars; the adoption of the aramid cord polyurethane coating glue bar ensures the strength and toughness of the longitudinal tension of the screen; by arranging the framework-free polyurethane rubber bar weft, the integrity of the screen is ensured, and the hole patterns between the weft are transversely deformed due to the elastic extension of the framework-free polyurethane warp, so that materials with the granularity close to the hole pattern size can smoothly pass through the screen, and the screening efficiency is improved; 3. the sieve plate not only has excellent wear resistance, corrosion resistance, oil resistance and aging resistance, but also has very strong toughness, and the bars can generate strong secondary high resonance when the sieve plate vibrates, thereby effectively preventing the phenomenon of hole blockage; 4. due to the design of the inverted trapezoid cross section of the bar, all sieve holes are inverted conical, which is beneficial to the sieving of materials; 5. the adoption of nonmetal materials such as aramid fiber rope, polyurethane, etc. under the prerequisite that does not reduce screen cloth intensity, greatly reduced the weight of screen cloth, easy to assemble and maintenance have reduced the energy consumption of sieve machine.
