Description

Technical Field

[0001] The invention belongs to the technical field of polyester yarn production, and in particular relates to a feeding guide device used for cationic polyester yarn processing. Background Art

[0002] Polyester is a synthetic fiber made of polyester ingredients. It is widely used in various textiles and industrial applications due to its good strength, durability and breathability. Polyester fiber can be produced through different processes, and polyester spinning process is a common textile process. The cationic polyester spinning process uses cationic polyester as raw material and spins it into yarn through a series of processing techniques. The yarn feed guide structure is required in the cationic polyester spinning process.

[0003] In the prior art, the tension of the conveyed yarn is generally adjusted by changing the distance between two guide wheels. During the conveying process of polyester yarn, the polyester yarn presents an M-shaped conveying trajectory, that is, a guide wheel is arranged on the left and right sides above a guide wheel. When the conveyed polyester yarn becomes loose, the yarn tension is adjusted by adjusting the distance between the guide wheels on the left and right sides above.

[0004] However, in the process of adjusting the distance between the two guide wheels, the polyester yarn is easily deviated from the middle position of the guide wheel. At the same time, it is inevitable that the yarn deviates from the middle position of the guide wheel during the yarn transportation process, thereby affecting the normal production of cationic polyester yarn. To this end, we provide a feeding guide device for cationic polyester yarn processing to solve the above problems. Summary of the invention

[0016] The present invention has the following beneficial effects:

[0017] 1. When the present invention detects that the polyester yarn is loose, the tension regulating part is controlled to move upward to push the second tensioning assembly to rotate upward. The annular tensioning wheel that rotates upward along the circumference of the first yarn guide wheel makes the polyester yarn further wound around the first yarn guide wheel. In this process, the rotation of the annular tensioning wheel is realized by the rotation of the running gear on the vertical gear seat. When the tension regulating part stops moving upward, the two horizontal tensioning wheels are controlled to move away from each other, so that the horizontally moving horizontal tensioning wheel gradually pushes the polyester yarn until the tension adjustment of the polyester yarn is completed.

[0018] 2. In the present invention, the inner inclined surfaces of the two annular tensioning wheels on the left and right sides of the first yarn guide wheel extend in opposite directions, and two conical rings are arranged inside the second yarn guide wheel. Through the action of the two relatively arranged annular tensioning wheels, the polyester yarn can be attached between the inner inclined surfaces of the two annular tensioning wheels, which can effectively prevent the polyester yarn from being greatly displaced during transportation. By arranging the two conical rings inside the second yarn guide wheel, it can be ensured that the polyester yarn is confined between the two conical rings during the polyester yarn guiding and conveying process, which can further prevent the polyester yarn from being greatly displaced during the feeding and guiding process.

[0019] 3. In the process of controlling the upward movement of the lifting and regulating frame, the present invention realizes the rotation of the annular tensioning wheel by the rotation of the traveling gear on the vertical gear seat, so that the polyester yarn attached to the inner wall of the first yarn guide wheel is gradually tightened. Since the length of the polyester yarn wound on the inner wall of the first yarn guide wheel gradually increases, the tension of the polyester yarn can be adjusted. In the process of driving the two horizontal moving seats away from each other, the polyester yarn is further pushed horizontally by the horizontal tensioning wheel, so as to achieve the tightening of the polyester yarn again. Under the horizontal pushing action of the horizontal tensioning wheel, the amount of polyester yarn attached to the second yarn guide mechanism is gradually increased, that is, the contact area between the polyester yarn and the second yarn guide mechanism is increased, so as to improve the stability of the polyester yarn guiding and conveying, thereby achieving the tension adjustment of the polyester yarn.

In this process, the first reset seat 802 is driven to slide along the first installation cavity 409 by the action of the oblique lifting frame 707, and then the upwardly moved oblique lifting frame 707 pushes the radial extension frame 703 to rotate upward, and the annular tensioning wheel 701 that rotates upward along the circumference of the first yarn guide wheel 401 makes the polyester yarn 11 further wound and attached to the inner wall of the first yarn guide wheel 401. In this process, the vertical support plate 503 The first tensioning assembly 6 is driven to move up to the specified position by the action of the traveling gear 702, and the annular tensioning wheel 701 is rotated by the rotation of the vertical gear seat 801, so that the polyester yarn 11 attached to the inner wall of the first yarn guide wheel 401 is gradually tightened (because the length of the polyester yarn 11 wound on the inner wall of the first yarn guide wheel 401 is gradually increased, the tension of the polyester yarn 11 can be adjusted), and then the tensioning control motor 606 is started by the controller to control the bidirectional screw 605 to run forward, and the bidirectional screw 605 and the water With the threaded cooperation of the translational moving seat 603, the two horizontal moving seats 603 are driven away from each other.

During the feeding and guiding process, the polyester yarn 11 is guided according to the attached Figure 1 and attached Figure 2 The feeding and conveying is carried out according to the conveying trajectory shown. During the guided conveying process, the stretched polyester yarn 11 generates a downward squeezing force on the arc-shaped pressure-bearing part 1002, and the squeezing force is transmitted to the pressure sensor 1004 through the pressure trigger disk 1003.

When the pressure value monitored by the pressure sensor 1004 drops below the set pressure value, it means that the polyester yarn 11 being fed and conveyed becomes loose. At this time, the controller receives the pressure value signal and starts the telescopic cylinder 504 to extend upward to drive the lifting and regulating frame 502 to move upward, and the tension adjustment of the polyester yarn 11 is completed through the above-mentioned tension control method.
