DETAILED DESCRIPTION
[0023] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.
[0024] like Figures 1 to 4 As shown, a yarn guide device for a double-layer woven surface pattern anti-deviating three-dimensional weaving equipment provided by an embodiment of the utility model comprises: a mounting plate 1 and a support rod 2, one end of the support rod 2 is arranged on the mounting plate 1, and a wire assembly 3 is arranged at the other end of the support rod 2 to limit the yarn, and a limiting sleeve 5 is arranged on the upper surface of the support rod 2; an anti-offline assembly 4, the anti-offline assembly 4 comprises a movable part and a wire fixing part 407, the movable part is arranged at one end of the support rod 2, and one end of the wire fixing part 407 is arranged in correspondence with the wire assembly 3 up and down to prevent the yarn from falling off;
[0025] Specifically, Figures 1 to 4 As shown, when in use, one end of the yarn first passes through the anti-offline component 4, then passes through the wire component 3, and then passes through the limiting sleeve 5. The three are used to perform multiple position limits on the yarn, thereby effectively avoiding deviation and causing problems in wire feeding.
[0026] Before use, the movable parts can be started to align the wire fixing part 407 with the conductor assembly 3 up and down, and then the yarn guide holes between the wire fixing parts 407 can be adjusted to adjust the yarns of different diameters to improve work efficiency. When the yarn breaks during use, the wire fixing part 407 can slide at one end at the same time to clamp and limit the yarn so that the yarn cannot fall down, thereby effectively avoiding the need for staff to search for thread ends on the weaving equipment after the yarn breaks, thereby increasing the speed of reinstallation, reducing the workload and labor intensity of the staff, and at the same time reducing downtime and improving work efficiency.
[0027] By using the conductor assembly 3, the range of yarn movement is adjusted according to the thickness of the yarn during use, so as to avoid the yarn sliding left and right, causing obstruction of the upper line and work errors, thereby achieving an enhanced limiting effect on the yarn.
[0028] Furthermore, the wire assembly 3 includes a first winding wheel 301, which is rotatably installed in the other end of the support rod 2, and the interior of the first winding wheel 301 is concave, and two groups of limit plates 302 are correspondingly arranged at the concave part; multiple groups of through holes 304 are provided on the outer side of the limit plates 302, and adjustment rods 303 are provided at both ends of the first winding wheel 301, and one end of the adjustment rod 303 is rotatably installed in the through hole 304;
[0029] Specifically, Figure 1 and Figure 2 As shown, the inner concave part of the first winding wheel 301 is the movable range of the yarn. When in use, according to the thickness of the yarn, the adjusting rod 303 is rotated to drive the limiting plate 302 to slide and adjust on the first winding wheel 301 to limit the yarn, thereby achieving the convenience of quick adjustment according to the yarn.
[0030] Furthermore, the movable part includes an electric push rod 401, one end of the output shaft of the electric push rod 401 is provided with a fixed seat 402, a second winding wheel 404 is rotatably installed in the fixed seat 402, and one end of the fixed seat 402 is provided with a movable rod 405;
[0031] Specifically, Figure 2 and Figure 3 As shown, before use, the electric push rod 401 can be started to drive the fixed seat 402 to extend, so that after the yarn passes through the limiting rod 4072, the fixed seat 402 extends forward again to adjust the tension of the yarn, thereby achieving the convenience of adjustment according to the usage situation and improving practicality.
[0032] Furthermore, the wire fixing component 407 includes a fixing cylinder 4071 and a plurality of limiting rods 4072. A slot 403 is provided on the lower surface of the fixing seat 402. The fixing cylinder 4071 is arranged in the slot 403. The plurality of limiting rods 4072 are equidistantly arranged in the fixing cylinder 4071. A semicircular slot 4073 is provided at one end of the limiting rod 4072.
[0033] Specifically, Figure 4As shown, the multiple groups of limiting rods 4072 can slide on the inner wall of the fixed cylinder 4071, so that they can also be adjusted according to the yarn before use to limit the yarn. When the thread breaks, the multiple groups of limiting rods 4072 will slide to one end, so that the semicircular grooves 4073 at one end contact each other to limit and fix the yarn, thereby achieving the effect of preventing the yarn from breaking, avoiding one end of the yarn from falling onto the weaving equipment, threatening the other working compartments, causing accidents, and affecting the effect of the weaving operation.
[0034] Furthermore, an electric telescopic rod 4074 is disposed on the upper surface of the limit rod 4072, and one end of the electric telescopic rod 4074 is disposed on the inner wall of the fixed tube 4071; sensors 406 are disposed on both sides of the fixed seat 402, and both ends of the movable rod 405 are respectively disposed on two sets of sensors 406, and the sensors 406 are electrically connected to the electric telescopic rod 4074;
[0035] Specifically, Figure 3 and Figure 4 As shown, during use, when there is no thread breakage, the limit rod 4072 always remains in a stressed and tightened state. Therefore, when the thread breaks, the limit rod 4072 is forced to contact, and one end of the limit rod 4072 will slide downward. At this time, a command will be issued to the sensor 406. At this time, the sensor 406 will start the electric telescopic rod 4074, and the electric telescopic rod 4074 will drive the limit rod 4072 to slide to one end to limit the yarn, thereby achieving a quick response when the thread breaks, thereby improving practicality.
[0036] The monitoring device of the utility model can adopt, for example, the STPO4 intelligent pressure switch sensor of Yatan Instruments.
[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
