Abstract

The invention relates to the technical field of spinning machines, and provides a turnover control roller which is arranged on a spinning machine bracket and comprises a movable plate movably hinged with the bracket, wherein a compression roller is rotatably connected to the movable plate; the pressing roller abuts against the leather ring under the action of gravity; and the bracket is also provided with a fixing component for fixing the pressing roller after the pressing roller is separated from the leather ring. When the yarn broken end, only need rotate the fly leaf to it is fixed through fixed subassembly, just can make the pinch roller break away from the leather collar, thereby effectual liberation operating personnel's both hands have improved work efficiency, and the yarn quality is better.

Description

Roll-over control roller

Technical Field

The invention relates to the technical field of spinning machines, in particular to a turnover control roller.

Background

In the process of drafting, the fiber needs to carry out necessary control on the yarn, so that the yarn thickness is more uniform, the yarn quality is better, the control roller is an important part in the spinning process, the clamping point of the feeding roller and the drafting roller is called a feeding jaw and a drafting jaw, the area between the two jaws is called a drafting area, the drafting area is provided with a apron part for supporting and holding the roving, the apron part has certain speed difference relative to the feeding roller, namely the apron speed is slightly higher than the linear speed of the feeding roller, so that the roving is subjected to certain pre-drafting, the drafting roller speed is higher than that of the apron, so that the yarn is gradually lengthened, the process is called drafting, and a set of rollers are generally used for applying certain pressure on the yarn on the apron. In order to prevent the yarn from being drawn more finely at the fine spots in the process, which results in fine details and poor quality of the finished yarn, a set of control rollers needs to be added. Traditional control roller needs operating personnel to take off when the yarn broken end to need reserve the space of placing, then connect, still need to put the roller back to original position at last, so not only complex operation, inefficiency moreover still can influence the yarn quality.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: the technical problems that the traditional control roller is complex in operation and low in efficiency when the yarn is broken and the quality of the yarn is affected are solved.

The invention provides a turnover control roller which is arranged on a frame and comprises a movable plate movably hinged with the frame, wherein a compression roller is rotatably connected on the movable plate; the pressing roller abuts against the leather ring under the action of gravity;

and the bracket is also provided with a fixing component for fixing the pressing roller after the pressing roller is separated from the leather ring.

When the yarn broken end, only need rotate the fly leaf to it is fixed through fixed subassembly, just can make the pinch roller break away from the leather collar, thereby effectual liberation operating personnel's both hands have improved work efficiency, and the yarn quality is better.

Further, the hinge shaft of the movable plate is provided with a screw in threaded connection with the bracket. So set up, simple structure not only, fly leaf easy dismounting moreover.

Further, the hinge point of the movable plate is located above the pressure roller. So set up, the stable support of the pinch roller of being convenient for is on the leather collar to make leather collar pressure remain stable.

Because the fly leaf rotates the back, resets under the action of gravity easily, so further improve and solve this problem, specifically, still be equipped with fixed subassembly on the support for the compression roller breaks away from leather collar after-fixing.

In order to explain the specific structure of the fixing component, in the scheme, the fixing component is a spring plate, and a curled edge is arranged on the inner side of the spring plate; the movable plate is provided with two fixed rods which are arranged in parallel and respectively abut against the support and the turned edge, so that the movable plate is turned and fixed.

Further, the elastic sheet is located above the movable plate. So set up, the interval between pinch roller and the leather collar is bigger to make workman's operating space bigger.

Drawings

The invention is further explained below with reference to the figures and examples;

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is an enlarged view at A in FIG. 1;

in the figure: 1. A support; 2. a movable plate; 3. a pressure roller; 4. a screw; 5. a spring plate; 6. and (5) fixing the rod.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.

As shown in fig. 1, the invention is a roll-over control roller, which is installed on a frame 1 of a spinning machine, and as shown in fig. 2, the roll-over control roller comprises a movable plate 2, the upper end of which is hinged with the frame 1, and a hinged shaft of the movable plate 2 is provided with a screw 4 in threaded connection with the frame 1, so that the arrangement is simple in structure and the movable plate 2 is convenient to disassemble and assemble.

A connecting plate is led out from the middle of the movable plate 2 in the vertical direction and is used for installing a rotatably connected compression roller 3; the lower end of the movable plate 2 is led out of the mounting plate in the vertical direction, the mounting plate is back to the connecting plate, and two fixed rods 6 which are arranged in parallel are mounted on the mounting plate. The support 1 is provided with an elastic sheet 5, and the inner side of the elastic sheet 5 is provided with a turned edge and forms a cylinder shape. When the pressing roller 3 needs to be separated from the leather ring, the movable plate 2 is rotated, the fixing rod 6 above the movable plate abuts against the support, and the fixing rod 6 below the movable plate abuts against the upper end of the turned edge, so that the movable plate 2 is turned and fixed. And after the operation is finished, the spring plate can slide out of the spring plate 5 with little force and return to the control position.

The pressing roller 3 abuts against the leather ring under the action of gravity; when the yarn broken end, only need rotate fly leaf 2, just can make compressing roller 3 break away from the leather collar to effectual liberation operating personnel's both hands have improved work efficiency, and the yarn quality is better.

Example two:

compared with the first embodiment, the differences are as follows: the elastic sheet 5 is located above the movable plate 2. So set up, the interval between pinch roller 3 and the leather collar is bigger to make workman's operating space bigger.

Example three:

compared with the first embodiment, the differences are as follows: the screw 4 is located above the pressure roller 3. So set up, be convenient for the stable support of pinch roller 3 and lean on the leather collar to make leather collar pressure remain stable.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
