Description
Technical field
The present invention relates to a kind of machinery making fiber, particularly relate to a kind of drawing of fiber mechanism, be specifically related to a kind of vinal drawing machine.
Background technology
At present, China is used for the dry heat drafting machine that polyvinyl alcohol special fibre is produced, and mainly contains domestic cold roll-type, domestic hot roller and import hot roller.In application, cold roll-type drawing machine owing to can not heat while drawing-off, although fibre bundle is through multistage drawing-off, is also difficult to reach desirable drawing-off effect.A kind of high-modulus high-strength polyvinyl fibre drafting machine is disclosed in Chinese patent ZL200720043935.3, this drawing machine is domestic hot roller, although structure comparison is reasonable, and cheap, drawing-off and heating can be carried out, but its design comparison is simple simultaneously, row's drawing roller operation room distance is less up and down, automatic controlling level is not high, and it does not have safety device, very easily occur because of carelessness or operate miss, and by rotary machine the situation of hindering.Import hot roller drawing machine, though can heat while drawing-off, machining accuracy is higher, but expensive, it also exists arranges drawing roller operation room up and down apart from less, and does not have safety device, also can occur because of carelessness or operate miss, and by rotary machine the situation of hindering.
Summary of the invention
The object of the present invention is to provide a kind of vinal drawing machine, this drafting machine structure more rationally, more safe and effective, and cheap.
The object of the present invention is achieved like this:
A kind of vinal drawing machine, it comprises motor, frame and hot-rolling, it is characterized in that: it also comprises photoelectric detection switch; Described hot-rolling, comprises roll body, roll shaft and steam swivel joint, and in application, this roll body is both as steam heater, again as fiber channel; The two ends of each roll body all arrange flange, and flange evenly arranges detect aperture, and in conjunction with the detect aperture evenly arranged, the signal that photoelectric detection switch exports is regular pulse signal, and consistent with the time interval of process tow curling round the roll; Described photoelectric detection switch is fixed in frame, and its transmitting terminal and receiving terminal are placed in detect aperture two ends with one heart, and photoelectric detection switch is safety device.
Above-mentioned photoelectric detection switch, preferably adopts infrared electro sense switch; Described detect aperture, number is at least 6, is preferably set to 8.Infrared electro sense switch is when normally working, and the signal that infrared beam transfers out is regular pulse signal, when there being tow curling round the roll, infrared electro detects the signal transferred out will be weakened, even interrupt, simultaneously by arranging requirement output alarm signal, reminding employees processes curling round the roll fiber in time.Very little, the time of process tow curling round the roll, especially the curling round the roll of the lower heat extraction roller of process was inconvenient very little for the number of application mid-infrared light electro-detection switch.
The thermo-roll surface at above-mentioned detect aperture place is provided with groove, and groove is preferably set to isosceles right triangle, and at the both sides of groove and tow contact point rounding, when processing tow curling round the roll, to avoid hot-rolling impaired.
Above-mentioned hot-rolling is preferably set to 5, and points two rows by upper three, lower two spread configurations in frame, be provided with siphon pipe in its roll body, use condensed water in middle roll body by this siphon pipe from the sucking-off of steam adapter, to avoid forming " steam hammer " phenomenon with during Steam Heating in hot-rolling.
Above-mentioned roll shaft is flatly arranged in frame, and its one end is fixedly linked with roll body is concentric, and its other end is placed in frame by bearing block, then is connected with steam swivel joint, and the steam condensate (SC) be conducive to like this in roll body is discharged in time.
In above-mentioned hot-rolling, angle angle between the direction that the center of circle of the horizontal direction of adjacent two hot-rollings of upper row and upper heat extraction roller and contiguous lower heat extraction roller is connected is 75 DEG C, adjacent two hot-rollings of upper row and lower heat extraction roller operation of vertical spacing are increased to 700 ~ 750mm, add the operation room distance of 2 ~ 3 times, increase the operating time for employee processes curling round the roll fiber in time, thus reach the safety ensureing employee.
The output shaft of above-mentioned motor is connected with the turning cylinder in frame, it is connected preferably by shaft coupling, this turning cylinder is connected with sprocket wheel by chain successively with hot-rolling, the i.e. sprocket wheel of this turning cylinder first and on upper row's tow import first hot-rolling, be connected successively according to the sprocket wheel on the hot-rolling of tow advance sequence, get back to turning cylinder by chain tension gear again and transmit power, hot-rollings all like this can share a motor, to ensure the uniformity of all hot-rolling linear velocities.
By cylinder, pressure roller is housed being in above the hot-rolling of wire vent side, with make the fibre bundle through heating, drawing-off orderly, regular be delivered to next operation, this pressure roller is rubber rollers.
The present invention has following beneficial effect:
This vinal drawing machine, structure is more reasonable, is easy to manufacture, cheap, achieves the drawing-off and heating of carrying out fiber simultaneously, and by the setting of the safety devices such as photoelectric detection switch, ensure that production safety.In practical application, the several infrared electro sense switches arranged, the signal that infrared beam transfers out when normal work is regular pulse signal, when there being tow curling round the roll, infrared electro detects the signal transferred out will be weakened, until interrupt, simultaneously by arranging requirement output alarm signal, reminding employees processes curling round the roll fiber in time.
