Description
Technical field
The present invention relates to a kind of machinery of making fiber, relate in particular 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 the 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 is owing to can not heating in drawing-off, although fibre bundle, through the multistage drawing-off, also is difficult to the drawing-off effect that reaches desirable.A kind of high-modulus high-strength polyvinyl fibre drafting machine is disclosed in Chinese patent ZL 200720043935.3, this drawing machine is domestic hot roller, although structure is more reasonable, and cheap, can carry out simultaneously drawing-off and heating, but its design comparison is simple, arrange up and down the drawing roller operation room apart from less, automatic controlling level is not high, and it does not have safety device, very easily occurs because of carelessness or operate miss, and is rotated the situation that machinery is hindered.Import hot roller drawing machine, though can heat in drawing-off, machining accuracy is higher, but expensive, it also exists arranges the drawing roller operation room up and down apart from less, and there is no safety device, also can occur because of carelessness or operate miss, and be rotated the situation that machinery is hindered.
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, comprise 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, evenly arrange on flange and detect hole, and in conjunction with the detection hole that evenly arranges, the signal of photoelectric detection switch output is regular pulse signal, and consistent with the time interval of processing the tow curling round the roll; Described photoelectric detection switch is fixed on frame, and its transmitting terminal and receiving terminal are placed in one heart and detect the two ends, hole, and photoelectric detection switch is safety device.
Above-mentioned photoelectric detection switch, preferably adopt the infrared electro sense switch; Described detection hole, number are at least 6, preferably are set to 8.The infrared electro sense switch is when normal operation, and the signal that infrared beam transfers out is regular pulse signal, when the tow curling round the roll is arranged, infrared electro detects the signal that transfers out will be weakened, even interrupt, by the requirement output alarm signal is set, reminding employees is in time processed the curling round the roll fiber simultaneously.The number of application mid-infrared light electro-detection switch very little, is processed the time of tow curling round the roll very little, and the curling round the roll of especially processing lower heat extraction roller is inconvenient.
Hot-rolling surface at above-mentioned detection hole place is provided with groove, and groove preferably is set to isosceles right triangle, and at both sides and the tow contact point rounding of groove, in order to when the curling round the roll of processing tow, avoid hot-rolling impaired.
Above-mentioned hot-rolling preferably is set to 5, and minutes two row by upper three, lower two spread configurations on frame, be provided with siphon pipe in its roll body, the condensed water in use in roll body, from the sucking-off of steam adapter, forms " steam hammer " phenomenon by this siphon pipe when avoiding with Steam Heating in hot-rolling.
Above-mentioned roll shaft flatly is arranged on frame, and the one end is fixedly linked with roll body is concentric, and its other end is placed on frame by bearing block, then with steam swivel joint, is connected, and the steam condensate (SC) that is conducive to like this in roll body is in time discharged.
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 ℃, adjacent two hot-rollings of upper row and lower heat extraction roller operation of vertical spacing are increased to 700～750mm, increased the operation room distance of 2～3 times, increase the operating time for the employee in time processes the curling round the roll fiber, thereby reach the safety that ensures the employee.
The output shaft of above-mentioned motor is connected with the turning cylinder on frame, it preferably is connected by shaft coupling, this turning cylinder is connected with sprocket wheel by chain successively with hot-rolling, namely this turning cylinder first with first hot-rolling of upper row's tow import on sprocket wheel, be connected successively according to the sprocket wheel on the hot-rolling of tow advance sequence, get back to turning cylinder and transferring power by chain tension gear again, all like this hot-rollings can share a motor, to guarantee the uniformity of all hot-rolling linear velocities.
Be in wire vent side hot-rolling above by cylinder, pressure roller is housed so that through the fibre bundle of 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 make, cheap, has realized carrying out simultaneously drawing-off and the heating of fiber, and the setting by safety devices such as photoelectric detection switch, has guaranteed production safety.In practical application, the several infrared electro sense switches that arrange, the signal that infrared beam transfers out when normal operation is regular pulse signal, when the tow curling round the roll is arranged, infrared electro detects the signal that transfers out will be weakened, until interrupt, by the requirement output alarm signal is set, reminding employees is in time processed the curling round the roll fiber simultaneously.
