Abstract
The utility model provides a drawing heat box for high-strength and high-modulus polyethylene fibers. The drawing heat box includes a working channel and an air duct which are arranged in a box body; a tow feeding inlet and a tow discharging outlet for feeding and discharging fiber tows are formed at two ends of the working channel; a fan is arranged in the air duct; both a wind inlet and a wind outlet formed at two ends of the air duct respectively are communicated with the working channel; and heaters are arranged on upper and lower wall bodies of the working channel and along the working channel; and wind direction regulations plates are arranged at the wind inlet and the wind outlet at two ends of the air duct respectively to facilitate the direction regulation of wind entering and leaving the working channel, and to enable the heating of fiber tows to be more uniform. Due to the arrangement of the heaters on the upper and the lower wall bodies of the working channel, the drawing heat box realizes the uniformity of both vertical temperature and temperate at two ends, thereby enhancing the heating uniformity of fiber tows, improving the heating effect and working efficiency and ensuring the product quality of fibers.
Description
Technical field
The utility model relates to a kind of process units of high-strength high-modulus polyethylene fiber, particularly a kind of high-strength high-modulus polyethylene fiber drafting heat box.
Background technology
High-strength high-modulus polyethylene fiber has high strength, high-modulus, high orientation, light weight, shock-resistant, dielectric properties advantages of higher, is bringing into play very important effect in fields such as modern war, Aero-Space, marine site defence, weaponrys; Simultaneously, this fiber also has wide application prospect in fields such as automobile, boats and ships, netting, medicine equipment, sports equipments.
In the production process of high-strength high-modulus polyethylene fiber, need fibre bundle is heated drawing-off, with promote the big molecule of polyethylene along fiber axis to orientation, changed to extended chain by folded chain, draw close mutually between the extended chain, active force strengthens each other, fiber increases with the strand quantity that adds tension force, the fracture strength of fiber is significantly improved, and ductility descends, and the fatigue strength that ABRASION RESISTANCE reaches all kinds of deformation also obviously improves.Present drafting heat box normally is provided with service aisle and air channel in its casing; The two ends of described service aisle are provided with thread a mouth and the filament mouth of advancing for the fibre bundle turnover; Be provided with blower fan, voltage balancer and heater in the described air channel, the air inlet at two ends, air channel and air outlet all interlink with service aisle.During work, be provided with drawing machine in the rear and front end of drafting heat box, fibre bundle is walked from service aisle, and by the hot blast that heater and blower fan provided in the air channel to the fibre bundle heating that circulates.Can be located among the air channel owing to its heater by existing drafting heat box, the length of service aisle is longer in addition, thereby at the two ends of service aisle and very easily occur the temperature difference up and down, make that being heated of fibre bundle is inhomogeneous, influenced the product quality that adds thermal effect and fiber of fiber.
The utility model content
For overcoming the deficiencies in the prior art, the high-module high-strength polyethylene fibre drafting heat box that the utility model provides a kind of rational in infrastructure, homogeneous heating, effectively improves the quality of products.
The technical scheme that its technical problem that solves the utility model adopts is: be provided with service aisle and air channel in the casing; The two ends of described service aisle are provided with thread a mouth and the filament mouth of advancing for the fibre bundle turnover; Be provided with blower fan in the described air channel, the air inlet at two ends, air channel and air outlet all interlink with service aisle; It is characterized in that: on lower wall on the service aisle, be equipped with the heater that distributes along service aisle.
Air inlet and air outlet place at the two ends, air channel are equipped with wind direction adjusting plate, so that regulate the direction of the wind of turnover service aisle, make being heated of fibre bundle more even.
The beneficial effects of the utility model are: because heater is arranged on the last lower wall of service aisle, make service aisle to reach the two ends temperature up and down even, thereby strengthened the being heated evenly property of fibre bundle, improving knows clearly adds thermal effect and operating efficiency, has guaranteed the product quality of fiber.
Description of drawings
Fig. 1 is the structural representation of utility model.
Among the figure: 1 for casing, 2 for the air channel, 3 for advance silk a mouth, 4 air inlets, 5 for service aisle, 6 for heater, 7 for side door, 8 for air outlet, 9 for observation window, 10 for wind direction adjusting plate, 11 for filament mouth, 12 be blower fan.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
High-strength high-modulus polyethylene fiber drafting heat box described in the utility model is provided with service aisle 5 and air channel 2 in its casing 1; The top of casing 1 is provided with several transparent observation windows 9, so that observe operation, the heating state of fibre bundle in service aisle 5; One side of casing 1 is provided with openable side door 7 corresponding to service aisle 5 places, so that manually connect silk behind the fibre bundle fracture of wire, and need not to open loam cake, and reduce heat loss.The two ends of described service aisle 5 are provided with thread a mouth 3 and the filament mouth 11 of advancing for the fibre bundle turnover; Be provided with blower fan 12 in the described air channel 2, the air inlet 4 at 2 two ends, air channel and air outlet 8 all interlink with service aisle 5.On lower wall on the service aisle 5, be equipped with the heater 6 that distributes along service aisle 5.The air inlet 4 at 2 two ends and air outlet 8 places are equipped with wind direction adjusting plate 10 in the air channel, so that regulate the direction of the wind of turnover service aisle 5, make being heated of fibre bundle more even.
Claims (2)
