Description

Technical Field

[0001] This invention relates to the field of heddle wire production technology, and in particular to a fine processing system and method for sliced ​​plastic heddle wire. Background Technology

[0002] Currently, some heddles are produced through injection molding. Due to mold, casting, or other issues, a significant amount of flash may form after demolding. Flash is a major factor affecting the usability of heddles, necessitating polishing. Because the heddle eyes are small, polishing is currently done manually with tools, resulting in poor polishing quality and impacting usability. Furthermore, the inner walls of the heddle eyes are generally straight. Since the heddle needs to move the yarn up and down during use, the cross-sectional shape at the junction of the heddle eye and the heddle surface is right-angled, easily leading to yarn wear and breakage, thus affecting production. Summary of the Invention

[0003] This invention proposes a precision processing system and method for sliced ​​plastic heddles, which solves the problems of poor polishing quality, low efficiency, and easy wear and tear on yarns from heddle eyes.

[0004] The technical solution of this invention is implemented as follows:

[0005] A precision processing system for slicing plastic heddles includes a fixed frame and a first slide rail and a second slide rail arranged opposite each other. Each of the first and second slide rails is equipped with several fourth sliders, and a limiting mechanism is provided between two fourth sliders. A scraping device, an inner polishing device, and an outer polishing device are symmetrically arranged at the upper and lower ends of the two slide rails. The scraping device is used to change the shape of the heddle eye, the inner polishing device is used to polish the heddle eye after its shape has been changed, and the outer polishing device is used to polish the right-angled edges of the heddle wire. Several devices are sequentially arranged on the fixed frame at the upper end of the slide rails. The scraping device includes a first hydraulic cylinder with a scraper rotatably mounted at its end. The inner polishing device includes a second hydraulic cylinder with a polishing head rotatably mounted at its end. The polishing head contains polishing fluid and has several through holes. The outer polishing device includes a third hydraulic cylinder with a support plate at its end. Polishing wheels are symmetrically tilted and rotated on the support plate, with the two polishing wheels forming a figure-eight shape.

[0006] The fixed frame is also equipped with a coating device, which includes a fourth hydraulic cylinder. The end of the fourth hydraulic cylinder is equipped with a coating rod, and the coating rod is equipped with a brush roller with coating material. This improves the wear resistance of the heddle eye, avoids the problem of the yarn wearing the heddle eye for a long time, and thus increases the roughness of the heddle eye, thereby improving the service life of the heddle yarn.

[0007] The limiting mechanism includes a connecting block connected to the fourth slider. The connecting block has a U-shaped groove, and a strap is provided on one side of the U-shaped groove to facilitate workers to quickly fix the workpiece.

[0008] The fixed frame is equipped with a connecting plate, and the connecting plate is equipped with several hot air guns. The hot air guns are located behind the coating device to facilitate the rapid drying of the workpiece after coating and improve the overall processing efficiency.

[0009] The scraping device is equipped with an infrared sensor for detecting workpieces, which can improve the overall automation level of the equipment and reduce the labor intensity of workers.

[0010] When the two scrapers and two polishing heads come into contact, their side lines form a semi-circle.

[0011] The two slide rails are symmetrically arranged with several first slide rails, second slide rails and third slide rails at their upper and lower ends. The scraping device is located on the first slide rail, the inner polishing device is located on the second slide rail, the outer polishing device is located on the third slide rail, and the slide rails are also provided with a fourth slide rail. The coating device is located on the fourth slide rail, which facilitates the processing of the hemmed holes and improves the versatility of the equipment.

[0012] One method for fine processing of sliced ​​plastic heddles includes the following steps:

[0013] (1) First, fix the workpiece on the limiting mechanism between the two fourth sliders, and then control the fourth slider to drive the workpiece to move.

[0014] (2) The workpiece is first moved to the scraping device and stopped. At the same time, the heddle of the workpiece is aligned with the scraper. The two first hydraulic cylinders are controlled to extend. The scraper contacts the heddle and then rotates to process the heddle, so that the inner wall of the heddle changes from a linear shape to an outer arc shape. After the processing is completed, the first hydraulic cylinder is reset.

[0015] (3) Then the workpiece is moved to the inner polishing device and stopped. The second hydraulic cylinder is extended so that the polishing head is inserted into the heddle eye and contacts the inner wall. At the same time, the polishing head is rotated. The polishing liquid is thrown out through the through hole by centrifugal force. The polishing head and polishing liquid polish the heddle eye. After polishing is completed, the second hydraulic cylinder is reset.

[0016] (4) Then move the workpiece to the outer polishing device and stop. The third hydraulic cylinder extends so that the polishing wheel contacts the right angle on the outside of the workpiece. Then rotate the polishing wheel to chamfer and polish the outside of the workpiece. After the processing is completed, the third hydraulic cylinder is reset and the workpiece is taken out.

[0017] Beneficial effects

[0018] This invention is rationally designed. By setting the waistline connecting line of the scraper and polishing head to be arc-shaped, the inner wall of the cylindrical heddle eye can be transformed into an outer arc shape. By changing the shape of the heddle eye, the smoothness of the heddle eye inlet and outlet and the inside of the heddle eye is greatly improved, reducing wear on the yarn and reducing the occurrence of yarn breakage. At the same time, the polishing liquid improves the polishing quality of the heddle wire, making the inside of the heddle eye smoother. In addition, the inlet and outlet of the heddle eye become trumpet-shaped, which facilitates the threading work. Furthermore, the external polishing device bevels the right-angled edges of the outer side of the heddle wire, preventing the heddle wire from cutting off adjacent yarns and ensuring the stable operation of the loom.
