Description

The hot-rolling of high-strength high-modulus polyethylene fiber drawing machine

Technical field

The utility model relates to a kind of drawing of fiber device, the particularly hot-rolling of high-strength high-modulus polyethylene fiber drawing machine.

Background technology

At present, be used to produce the hot-rolling of the drawing machine of high-strength high-modulus polyethylene fiber, it is by conduction oil or biphenyl, Steam Heating, the machining accuracy height, and difficult sealing is easily revealed, and dependence on import, costs an arm and a leg the production cost height.

The utility model content

For overcoming the deficiencies in the prior art part, the utility model provide a kind of rational in infrastructure, be easy to make, the hot-rolling of cheap drawing machine.

The technical scheme that its technical problem that solves the utility model adopts is: comprise roll body, roll shaft and heater, roll shaft places the inner chamber of roll body, and the inner of roll shaft and roll body are fixedly linked; Heater also places the inner chamber of roll body.

Above-mentioned heater is the cast aluminium electric heater.

The beneficial effects of the utility model are: simple and reasonable for structure, changed existing hot-rolling by conduction oil or biphenyl, the existing machining accuracy height of Steam Heating, difficult sealing, the weak point easily revealed, be easy to make, reduced production cost, improved economic benefit.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment.

Among the figure: 1 is that roll shaft, 2 is bearing block for back-up ring, 11 for locking nut, 10 for bearing, 9 for felt pad, 8 for the frame of drawing machine, 7 for roll body, 6 for heater, 5 for gland, 4 for bolt, 3.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

The utility model comprises: roll body 5, roll shaft 1 and heater 4, and roll shaft 1 places the inner chamber of roll body 5 with one heart, and (right side) end is fixedly linked with roll body 5 by gland 3 and bolt 2 in it.Cast aluminium electric heater 4 also places the inner chamber of roll body 5, and is placed on one heart on the roll shaft 1.

During use, the outer end (left side) of heater 4 of the present utility model and the frame 6 of drawing machine are fixed, connect power supply.One end (left side) of roll body 5 places on the frame 6 of drawing machine by Z-shaped bearing block 11 and bearing 8, roll body 5 lumen openings places seal with felt pad 7, the roll shaft 1 usefulness locking nut 9 that is positioned at frame 6 places of drawing machine carries out relative fixed, and is provided with back-up ring 10 in the left end outside and 6 of the frames of roll body 5.Use the same method again four or six the utility model are installed on the frame 6 of drawing machine, constitute five rollers or seven roller drawing machines, again a roll shaft 1 is wherein linked to each other with the motor of drawing machine, to obtain power.During work, the power of motor transfers to other hot-rolling successively by coupled roll shaft 1, and this moment, roll body 5 rotated with its roll shaft 1, and heater 4 does not change.Fibre bundle is around on each hot-rolling successively, heats, drawing-off.
