Abstract
The utility model relates to a filament spray hole for production of artificial turf filaments. The filament spray hole is formed on a filament spray plate in a unit die head and is provided with a runner, a plurality of reinforcing rib grooves are evenly arranged in the runner along the filament extruding direction, a separation distance between every two adjacent reinforcing rib grooves in the plurality of reinforcing rib grooves is 0.4mm-0.8mm, the maximum inner diameter of the positions in the runner provided with the reinforcing rib grooves is larger than that of the positions in the runner provided with no reinforcing rib groove, and the ratio of the maximum inner diameter of the positions in the runner provided with the reinforcing rib grooves to the maximum inner diameter of the positions in the runner provided with no reinforcing rib groove is in a range of 1.1-3. Artificial filaments produced by the filament spray hole provided with the reinforcing rib grooves are provided with reinforcing ribs, an artificial turf made of the filaments has good drainage performance, abrasive resistance, bulk density and rebound resilience, touch feeling of the artificial turf formed by weaving the filaments is extremely similar to touch feeling of a real turf, the improvement cost is low, the filament spray hole is practical, and the problem that filaments spun by a traditional spinning machine are hard and non-abrasion-resisting is effectively solved.
Description
Technical field
The utility model relates to a kind of spinneret orifice, relates in particular to a kind of spinneret orifice for the production of the bent silk of chinampa.
Background technology
Pedaline is developed into the history of now existing four more than ten years, and the pedaline technique functions comes from the U.S. of nineteen sixties, at first is applied to the rugby court, and very fast American football, baseball and the Association football field of just being applied to.Just accept chinampa abroad gradually to the eighties, earlier 2000s just enters Chinese market, and very fast quilt masses accept and develop rapidly.Pedaline has overcome the several main difficult points of natural grass: the one, under extreme weather conditions, can't grow; The 2nd, some countries and regions are because economic cause can't be paid high maintenance cost; The 3rd, in having the stadiums of ceiling, some can't plant.Except these, pedaline also has the frequency of utilization height, mats formation easily, maintaining is simple, draining characteristics efficiently, and these advantages all make pedaline have wide development space, and the trend that replaces natural grass is arranged greatly!
Spin processes is generally adopted in the production of the bent silk of chinampa, and traditional spinning machine, spun silk pliability and ABRASION RESISTANCE are not enough, and the simulative grass effect is bad.
Summary of the invention
The technical problems to be solved in the utility model is: in order to solve traditional spinning machine, spun silk pliability and ABRASION RESISTANCE are not enough, the problem that the simulative grass effect is bad, the utility model provide a kind of spinneret orifice for the production of the bent silk of chinampa to solve the problems referred to above.
The technical solution of the utility model is: a kind of spinneret orifice for the production of the bent silk of chinampa, be arranged on the spinnerets in the unit die head, has runner in the described spinneret orifice, the direction of extruding along bent silk in the described runner evenly is provided with a plurality of reinforcement grooves, the spacing of extruding two adjacent reinforcement grooves of direction along bent silk in described a plurality of reinforcement groove is 0.4mm-0.8mm, have the maximum inner diameter at reinforcement groove place in the described runner greater than the maximum inner diameter at no reinforcement groove place, the ratio of the maximum inner diameter that has reinforcement groove place in the described runner and the maximum inner diameter at no reinforcement groove place is in the scope of 1.1-3.When material process spinneret orifice, the material that is in the center in the spinneret orifice is faster than the flow velocity of material on every side, can produce a shearing force, after having been arranged, the reinforcement groove of a projection can produce a cushion effect to material, the silk of ejection can be more soft like this, fidelity is higher, and intensity and the ABRASION RESISTANCE of silk all can improve.
According to actual needs, the cross section at no reinforcement place is rectangle or circle in the described runner.
As preferably, described reinforcement groove is circular arc.
The spacing of two adjacent reinforcement grooves is 0.75mm in described a plurality of reinforcement groove.The maximum inner diameter that has reinforcement groove place in the described runner is 1.2 with the ratio of the maximum inner diameter at no reinforcement groove place.According to the experiment repeated detection, better according to silk drainage, ABRASION RESISTANCE and resilience that the spinneret orifice of above-mentioned numerical Design is produced.
The beneficial effects of the utility model are: the artificial bent silk of the band reinforcement that the spinneret orifice that has the reinforcement groove of the present utility model is produced, the chinampa of making has good drainage, ABRASION RESISTANCE, bulk density and resilience, human body is extremely similar to true lawn for the sense of touch of the chinampa that this bent silk weaves out, improve with low cost, be suitable for practicality, effectively solved the hard not wear-resisting problem of the spun silk of traditional spinning machine.

Fig. 1 is die head schematic diagram of the present utility model,
Fig. 2 is the structural representation of the optimum embodiment of spinneret orifice of the present utility model.
Among the figure 1, the unit die head, 2, spinnerets, 3, spinneret orifice, 4, runner, 5, the reinforcement groove.
The specific embodiment
As Fig. 1-shown in Figure 2, the utility model is for the production of the spinneret orifice of the bent silk of chinampa, spinneret orifice 3 is arranged on the spinnerets 2 in the bent silk of the chinampa unit die head 1, has runner 4 in the spinneret orifice 3, the direction of extruding along bent silk in the runner 4 evenly is provided with a plurality of reinforcement grooves 5, have the maximum inner diameter at reinforcement groove 5 places in the runner 4 greater than the maximum inner diameter at no reinforcement groove 5 places, the cross section at no reinforcement 5 places is rectangle or circle in the runner 4, and reinforcement groove 5 is circular arc.
Embodiment 1: the spacing of extruding two adjacent reinforcement grooves 5 of direction along bent silk in a plurality of reinforcement grooves 5 is 0.4mm, and the maximum inner diameter that has reinforcement groove place in the runner 4 is 1.1 with the ratio of the maximum inner diameter at no reinforcement groove place.
Embodiment 2: the spacing of extruding two adjacent reinforcement grooves 5 of direction along bent silk in a plurality of reinforcement grooves 5 is 0.6mm, and the maximum inner diameter that has reinforcement groove place in the runner 4 is 2 with the ratio of the maximum inner diameter at no reinforcement groove place.
