Technical Field

[0001] The utility model relates to the technical field of covered yarn machines, in particular to a covered yarn machine for producing Oxford cloth. Background Art

[0002] Oxford cloth is a wear-resistant and waterproof fabric. Oxford cloth is made of warp and weft. In order to improve the wear resistance of Oxford cloth, a layer of wear-resistant yarn is often coated on the surface of the warp or weft. When coating, a coating yarn machine is required. The two yarns are respectively drawn out from the two spindles and guided through the guide ring. The wear-resistant yarn is coated on the main yarn, and then the coated yarn is finally collected.

[0003] After searching, the Chinese patent with the authorization announcement number CN214244713U discloses a covering yarn machine, including a main unit for supporting, and also including an outer covering yarn device for supporting the outer fiber filament. The bottom of the main unit is evenly distributed with a number of winding devices for winding the finished product, and the main unit is equipped with a drive device for driving the winding device to rotate. The automatic sliding setting of the winding device facilitates the disassembly and replacement of the winding roller, improving the convenience of use; the automatic reset setting of the winding device facilitates the individual disassembly and replacement of each winding roller, ensuring the efficiency of the covering yarn; the unified setting of the drive device simplifies the structure and ensures the smooth operation of other covering yarns when the winding roller is replaced.

[0004] The above patent uses a guide ring to guide the passing silk thread, but as the use time increases, the silk thread contacts the same position of the inner wall of the guide ring for a long time, causing wear of the inner wall of the guide ring. After wear, the friction between the contact position between the inner wall of the guide ring and the silk thread increases, which easily causes roughness on the surface of the silk thread and affects the subsequent coating quality. Therefore, the present application provides a silk coating machine for Oxford cloth production to meet the needs. Utility Model Content

[0029] like Figures 1-4 As shown, the embodiment of the present invention provides a covered yarn machine for Oxford cloth production, comprising a machine body 1, a mounting seat 2 is mounted on the side of the machine body 1, two connecting blocks 3 are fixed on the side of the mounting seat 2, a guide ring 4 is provided on the side of the connecting block 3 away from the mounting seat 2, the number of the guide rings 4 is two, and the two guide rings 4 guide the two silk threads respectively, an arc groove is provided on the side of the connecting block 3 away from the mounting seat 2, the inner wall of the arc groove is rotatably connected to the surface of the guide ring 4, the inner wall of the guide ring 4 is provided with a curved surface 5, and a plurality of arc notches 6 are provided on the curved surface 5, and a plurality of arc notches 6 are provided on the curved surface 5. The arc-shaped notches 6 are distributed in a circular array with the center of the guide ring 4 as the center of the array, so that several arc-shaped notches 6 contact the wire in turn to prevent excessive wear at the same arc-shaped notch 6, thereby preventing the surface of the wire from being rough and ensuring the subsequent coating quality. The opposite sides of the inner wall of the arc-shaped notch 6 are provided with inclined surfaces 7, and the inclined surfaces 7 are used to guide the wire stuck in the arc-shaped notch 6, so as to facilitate the wire to be stuck in the arc-shaped notch 6. A groove 12 is provided on the circumferential surface of the guide ring 4, and a positioning member 13 is provided in the connecting block 3. The positioning member 13 is stuck in the groove 12 for positioning the guide ring 4.

[0030] like Figure 4 As shown, in this embodiment, arc-shaped strips 10 are fixed to the top and bottom of the inner wall of the arc-shaped groove, and annular grooves 8 are provided on the top and bottom of the guide ring 4. The inner wall of the annular groove 8 is rotatably connected to the side of the arc-shaped strip 10. When the guide ring 4 rotates, the annular groove 8 is driven to rotate along the surface of the arc-shaped strip 10, and the rotation of the guide ring 4 is made smoother and more stable by the arc-shaped strip 10.

[0031] like Figure 2As shown, in this embodiment, both ends of the arc strip 10 are provided with circular chamfers, which reduce the sticking between the inner wall of the annular groove 8 and the end edge of the arc strip 10 when the guide ring 4 rotates, making the rotation of the guide ring 4 more stable and smooth.

[0032] like Figure 4 As shown, in this embodiment, an annular groove 29 is provided on the circumferential surface of the guide ring 4, and an arc-shaped strip 211 is fixed to the inner wall of the arc-shaped groove. The side surface of the arc-shaped strip 211 is rotatably connected to the inner wall of the annular groove 29. When the guide ring 4 rotates, it rotates along the arc-shaped strip 211, and the rotation of the guide ring 4 is further guided by the arc-shaped strip 211, so that the rotation of the guide ring 4 is more stable and smooth.

[0033] like Figure 4 As shown, in this embodiment, the inner wall of the annular groove 2 9 is provided with an arc surface, and the shape of the arc strip 2 11 is adapted to the shape of the arc surface. Through the design of the arc surface, the contact area between the inner wall of the annular groove 2 9 and the arc strip 2 11 is increased, thereby improving the guiding ability of the arc strip 2 11 to the guide ring 4.

[0034] like Figure 2 and Figure 4 As shown, in this embodiment, the central axis of the annular groove 2 9 coincides with the central axis of the guide ring 4 , and when the guide ring 4 rotates, the annular groove 2 9 is driven to rotate smoothly along the arc strip 2 11 .

[0035] like Figure 3 and Figure 4 As shown, in this embodiment, the positioning member 13 includes a square cavity 16 opened inside the connecting block 3, and a connecting plate 15 is slidably connected in the square cavity 16. A tension spring 17 and two bayonet pins 14 are fixed on one side of the connecting plate 15 close to the guide ring 4. The tension spring 17 is located between the two bayonet pins 14. One end of the bayonet pin 14 away from the connecting plate 15 movably penetrates the connecting block 3 and fits against the inner wall of the groove 12. The end of the tension spring 17 away from the connecting plate 15 is fixedly connected to the side of the inner wall of the square cavity 16 close to the guide ring 4. Rotating the guide ring 4 drives the groove 12 to rotate, and the inner wall of the groove 12 squeezes the bayonet pin 14. The end of the bayonet 14 is hemispherical, and the shape of the groove 12 is adapted to the shape of the bayonet 14, so that the bayonet 14 drives the connecting plate 15 to move along the inner wall of the square cavity 16, and the connecting plate 15 drives the tension spring 17 to be in a stretched state. When the bayonet 14 is separated from the groove 12, the guide ring 4 can be rotated smoothly. After rotating to the appropriate position, the bayonet 14 is stuck in the corresponding groove 12 under the tension of the tension spring 17, thereby realizing the positioning of the guide ring 4. The end of the bayonet 14 is hemispherical, and the shape of the groove 12 is adapted to the shape of the bayonet 14, thereby preventing the bayonet 14 from being stuck in the groove 12 and causing the guide ring 4 to be unable to move.

[0036] Working principle: When the silk thread passes through the guide ring 4, it fits with the inner wall of the arc-shaped notch 6. After using it for a period of time, the guide ring 4 is rotated to make the guide ring 4 rotate along the surface of the arc-shaped strip 10 and the arc-shaped strip 2 11. At this time, the guide ring 4 drives the inner wall of the groove 12 to squeeze the pin 14, so that the pin 14 drives the connecting plate 15 to move along the inner wall of the square cavity 16. The connecting plate 15 drives the tension spring 17 to be in a stretched state. After rotating the guide ring 4 to a suitable angle, the silk thread is stuck in the corresponding arc-shaped notch 6. At the same time, the pin 14 is stuck in the corresponding groove 12 under the tension of the tension spring 17, so as to realize the positioning of the guide ring 4, and then the silk thread can continue to be guided. When the guide ring 4 needs to be rotated again, the above steps can be repeated, and the inclined surface 7 in the arc-shaped notch 6 is used to guide the silk thread to be placed in the arc-shaped notch 6, thereby facilitating the placement of the silk thread in the arc-shaped notch 6.

[0037] The present invention encompasses any substitutions, modifications, equivalent methods, and solutions that are not within the spirit and scope of the present invention. To provide a thorough understanding of the present invention, specific details are described in detail in the preferred embodiments of the present invention above, but those skilled in the art can fully understand the present invention without these detailed descriptions.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
