Abstract

The utility model provides a buffer cylinder head, relating to a self-stop device of cylinder pressurizing and roller lapping detecting, in particular to security detection of the cylinder pressurizing mode of the traction roller and the drafting roller used in the combined production line of the post-processing of the chemical fiber for the equipment of traction and drafting. The buffer cylinder head comprises a pin shaft (1), a spring (2), an adjusting shaft (3) and a column pin (4). The adjusting shaft is sheathed with the spring. The head part of the adjusting shaft is provided with a radial via hole in which the column pin is mounted. The end part of the pin shaft is provided with a deep hole used for connecting the adjusting shaft. The head part of the adjusting shaft and the deep hole at the end part of the pin shaft are connected. The end part of the pin shaft is provided with two oppositely arranged coordinating long waist-holes used for mounting the column pin. The buffer cylinder head of the utility model has simple structure, long service life, practicality, and reliability, and is matched with the self-stop device without occupying extra space.

Description

The cushion gas cylinder head

(1) technical field

The utility model relates to the pressurization of a kind of cylinder, around the automatic stop arrangement that roller detects, relate in particular in a kind of traction that is used for chemical fibre post processing combined production line, the draft apparatus safety detection of carry-over pinch rolls, drawing roller upper cylinder pressuring method.

(2) background technology

At present; make the hauling machine of production line in the tow drawing process of large-tonnage polyster fibre post processing; all be equipped with the fiber of cylinder pressurization to detect automatic stop arrangement on the drawing machine around roller; the principle of this automatic stop arrangement is: combined production line is under normal operating condition; because of lousiness; fracture of wire; or because the unstable caused winding carry-over pinch rolls of other state of the art of tow surface; grip block is with lifting on the wrapping wire progressive additive; do not resist the reaction force of grip block when cylinder; the angular displacement of hinged generation hinge support; contact breaks away from the plush copper of electric executive component microswitch; microswitch sends signal; cylinder piston rod pull-up grip block; instruct simultaneously that the seal wire of combined production line---crimping segment stops, thereby can protect equipment and remove wrapping wire for stopping.

But in actual use,, adopt and concentrate pressure regulation air feed in parallel, compressed air accurately can not be adjusted to the pressure that is not enough to overcome generation wrapping wire phenomenon, so usually adopt pressure bigger than normal in order to simplify gas circuit.Since take place hair, fracture of wire around the roller phenomenon be at random, uncertain, at single drawing roller, the counter-pressure that wrapping wire produces is impacted bigger to cylinder, and influences cylinder service life, so the gudgeon of cylinder or piston rod often have the generation phenomenon of rupture.

In order to address the above problem, this kind equipment in addition following improvement at present: keep the cylinder pressuring method, change hinge support angular displacement and microswitch signalling form into mechanical linkage contact apparatus, the attached drawing roller surface of leaning on of stock contact, send signal by sensor or limit switch, draw and lift cylinder and parking.Because the many and complex structure of this cover mechanism element, connecting rod exposes easy extension silk, twines silk, the operation maintenance is proposed requirements at the higher level, particularly this covering device enlarged original limited installing space again.

(3) summary of the invention

The utility model has overcome cylinder short, the baroque defective in service life of existing automatic stop arrangement, and a kind of cushion gas cylinder head is provided.The utility model bounce cylinder header structure is simple, and cylinder prolongs service life, and is practical reliable; Supporting with automatic stop arrangement, additionally do not take up room.

The utility model is achieved in that a kind of cushion gas cylinder head, comprise bearing pin, spring, adjustment axle and straight pin, adjust on the axle and be with spring, adjust shaft head and have radial direction through hole, straight pin is housed in the through hole, the afterbody of bearing pin is useful on deep hole that connect to adjust axle, adjust the head of axle and the afterbody deep hole of bearing pin and link, the afterbody of bearing pin have be used to install straight pin to wearing the coordination long lumbar hole.

Above-mentioned cushion gas cylinder head, the tail end of described adjustment axle is connected with cylinder piston rod, and the head end of bearing pin connects with the hinge bar on the grip block.

Operation principle of the present utility model is as follows: an original hard cylinder head is replaced by cushion gas cylinder head of the present utility model, original rigid connection is transformed into flexibly connects.Under the normal fast running status of production line; because of lousiness; the drawing roller surface wrapping wire that other state of the art instabilities of fracture of wire or tow cause; cause lifting on the winding silk of grip block with progressive additive; spring in the utility model strengthens compress variation thereupon gradually; make hinge support produce angular displacement; the contact on hinge support top breaks away from the microswitch plush copper gradually; the microswitch action is also sent signal; the action of instruction cylinder; cylinder lifts grip block; simultaneously combined production line seal wire---crimping segment stops in emergency, thereby realize safety protection function to cylinder around the roller automatic stop arrangement.The utility model bounce cylinder header structure is simple, and cylinder prolongs service life, and is practical reliable; Supporting with automatic stop arrangement, additionally do not take up room.

(4) description of drawings

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Fig. 1 is the assembly structure figure of the utility model cushion gas cylinder head;

Fig. 2 is an A-A sectional drawing among Fig. 1;

Fig. 3 is of the present utility model around the roller automatic stop arrangement for using.

Among the figure: 1 bearing pin, 2 springs, 3 adjust axle, 4 straight pins, 5 carry-over pinch rolls, 6 grip blocks, 7 cylinders, 8 is hinged, 9 microswitches.

(5) specific embodiment

Referring to Fig. 1, Fig. 2 and Fig. 3, a kind of cushion gas cylinder head, comprise bearing pin 1, spring 2, adjust axle 3 and straight pin 4, adjust on the axle 3 and be with spring 2, spring 2 one ends are near adjusting axle 3, and the other end is adjusted axle 3 heads and had radial direction through hole near bearing pin 1, straight pin 4 is housed, the straight pin 4 fixing axles of adjusting in the through hole; The afterbody of bearing pin 1 is useful on and connects the deep hole of adjusting axle 3, adjusting the head of axle 3 and the afterbody deep hole of bearing pin 1 links, the afterbody of bearing pin 1 have be used to install straight pin 4 to wearing the coordination long lumbar hole, this is to wearing coordination long lumbar hole can be used to the to limit the quantity of compressive deformation of spring 2.The tail end of adjusting axle 3 is connected with cylinder piston rod, and the head end of bearing pin 1 connects with the hinge bar on the grip block.The drawing roller surface wrapping wire that combined production line causes because of other state of the art instabilities of lousiness, fracture of wire or tow; lift on the winding silk of grip block with progressive additive; spring 2 strengthens compress variation thereupon gradually; make hinged 8 among Fig. 3 produce the hinge support angular displacements; the contact on hinged 8 tops breaks away from microswitch 9 plush coppers gradually; microswitch 9 sends signal; 7 actions of instruction cylinder; lift grip block 6; simultaneously combined production line seal wire---crimping segment stops in emergency, thereby realize safety protection function around the roller automatic stop arrangement.
