Description
Technical Field
The invention relates to textile machinery, in particular to a front compression roller microswitch of an FA306 drawing frame.
Background
The drawing frame is used for improving the internal structure of the sliver so as to improve the uniformity of long sections of the sliver, simultaneously reducing the weight unevenness, straightening and paralleling fibers in the sliver, reducing hooks, enabling the fineness to accord with the specification, and enabling raw materials of different types or different qualities to be uniformly mixed to achieve the specified mixing ratio.
The drawing frame works with the tasks of drawing, doubling, drafting, mixing and loop forming. The thick and thin sections of the sliver have the opportunity of random overlapping, so that the evenness of the long and middle sections of the cooked sliver is improved, and the cooked sliver is regularly placed in a sliver can after being combined, drawn, bunched and pressed by a front pressing roller. It can be seen that the draw frame consists of a feed section, a drafting section, a sliver forming section and some automation. The sliver forming part consists of a bell mouth, a compression roller and a sliver coiler and has the function of pressing a cotton belt into a compact and smooth sliver so as to reduce the accidental elongation of the sliver when the sliver is led out, and the sliver compressed by the compression roller enters an inclined tube gear of the sliver coiler and is coiled into a sliver can in a cycloid shape. In addition, the drawing frame needs to be provided with automatic stop devices with high sensitivity, including automatic stop devices such as winding rollers and broken ends in front of the drawing frame, automatic stop devices for broken ends and broken strips after the drawing frame is manufactured, and safety automatic stop devices.
The pressing roller of the FA306 drawing frame consists of a front pressing roller and a rear pressing roller, wherein the left side of the front pressing roller is provided with a bakelite tooth gear made of bakelite, the right side of the front pressing roller is provided with a rolling bearing, and a shifting block is arranged on a right machine base and is pressed by the rolling bearing in front of a microswitch to work. When the compression roller is continuously wound, the shifting block controls the micro switch to be disconnected through the spring force, and the equipment stops, so that the equipment is protected.
In daily operation, the role of the bakelite tooth gear is: firstly, reduce the equipment noise, secondly in the stop failure, preceding compression roller twines the cotton back, and the bakelite tooth atress is damaged to protection equipment and prevention condition of a fire take place. However, because the existing microswitch seat is unreasonable in design, after the compression roller is wound with the cotton, the microswitch on the switch seat does not have the parking function, and the front compression roller is wound with the cotton continuously, so that bakelite teeth on the front compression roller are twisted, some bakelite teeth are even twisted and bent, the bakelite teeth are difficult to correct, and particularly under the condition that varieties are difficult to open, the damage amount of the bakelite teeth is larger, the loss of accessories of equipment is increased, the operation efficiency is low, and the production is influenced.
disclosure of Invention
The invention aims to solve the technical problem of providing the FA306 drawing frame front press roller microswitch which can thoroughly solve the problem that the bakelite teeth of the FA306 drawing frame are easy to damage, avoid the twisting of the front press roller and eliminate the fire caused by the problem.
In order to solve the technical problem, the front press roller microswitch for the FA306 drawing frame comprises a left base and a right base which are arranged in parallel, wherein the upper parts of the left base and the right base are connected with supporting plates; a front compression roller and a rear compression roller are arranged between the left base and the right base in parallel; the right base is provided with a shifting block, and the shifting block is parallel to the front press roller; a square base is arranged on the right base on one side of the shifting block, and a microswitch is arranged on the square base; the drawing frame operates when the shifting block presses and touches the micro switch, and stops when the shifting block is separated from the micro switch.
The invention changes the operation mode of the existing microswitch from normal open to normal close. When the equipment normally operates, the shifting block continuously presses and touches the microswitch; when the compression roller is wound continuously, the compression roller is disconnected, the shifting block leaves the microswitch, the equipment is stopped, and the damage is avoided.
Preferably, the square base is fixed on the right base through a base set screw; the microswitch is fixed on the square base by a microswitch set screw. The technical scheme is convenient for the quick overhaul and maintenance of the microswitch.
Preferably, the base set screw and the square base connecting part are provided with waist-shaped holes. The waist-shaped hole is arranged, so that the micro switch can be quickly adjusted when the weight is changed.
Preferably, the square base is 70mm long, 28mm wide and 4.5mm thick. By adopting the technical scheme, the convenient and flexible retention in a narrow equipment space can be ensured, the structural strength requirement can be ensured, and the service life is long.
When the equipment runs with small thickness, the shifting block can leave the microswitch, the equipment stops, and the car is driven after the check of a car stop worker, so that the product quality is ensured.

Fig. 2 is a schematic structural diagram of the present invention.
Detailed Description
the invention is further described with reference to the accompanying drawings in which:
As shown in fig. 1 and 2, the FA306 drawing frame front press roller microswitch provided by the invention comprises a left machine base 10 and a right machine base 9 which are arranged in parallel, wherein the upper parts of the left machine base 10 and the right machine base 9 are connected with a supporting plate 2; a front compression roller 7 and a rear compression roller 3 are arranged between the left base 10 and the right base 9 in parallel; the right base 9 is provided with a shifting block 6, and the shifting block 6 is parallel to the front press roller 7; a square base 4 is arranged on a right base 9 on one side of the shifting block 6, and a microswitch 5 is arranged on the square base 4; the drawing frame operates when the shifting block 6 presses and touches the microswitch 5, and the drawing frame stops when the shifting block 6 is separated from the microswitch 5.
Preferably, the square base 4 is fixed on the right base 9 through a base set screw 4 b; the microswitch 5 is fixed on the square base 4 by a microswitch set screw 5 a.
Preferably, the base fastening screw 4b and the square base 4 are provided with a waist-shaped hole 4a at the connection part.
Preferably, the square base 4 is 70mm long, 28mm wide and 4.5mm thick.
