Description

Technical Field

[0001] The present invention relates to the technical field of textile equipment, and particularly relates to a yarn centralized guiding device for textile machinery. Background Art

[0002] With the development of the economy, people's demand for textile products is increasing. The improvement of textile equipment plays a great role in promoting the efficiency of textile production. A textile factory refers to a workshop that manufactures production materials or means of livelihood with machinery. Yarn is a kind of textile product, which is made from various textile fibers processed into products of a certain fineness and is used for weaving, rope making, thread making, knitting, embroidery, etc. It is divided into short fiber yarn, continuous filament, etc.; Before the finished product, the yarn needs to be wound into a bobbin for easy packaging and use of the yarn. The yarn is generally wound on a textile reel, and the entire winding process is an automated operation. After the winding is completed, only the textile reel needs to be manually taken and placed.

[0003] In the process of yarn conveying of existing textile machinery, a guiding device is needed to gather multiple yarns together to facilitate the subsequent rope twisting work. However, if the yarns become loose during the guiding and gathering process, the subsequent rope twisting work cannot proceed normally. Therefore, a tension adjusting mechanism needs to be set up. Most of the existing tension adjusting mechanisms are tension adjusting rollers. When the yarns become loose, manual adjustment is required, and the loose situation cannot be known in advance, which will surely cause rope twisting disorders and affect the quality.

[0004] To solve the above problems, we propose a yarn centralized guiding device for textile machinery. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems in the background art, and to propose a yarn centralized guiding device for textile machinery.

[0006] To achieve the above purpose, the present invention adopts the following technical solutions:

Each button is electrically connected to the corresponding indicator light.

[0009] In the above-mentioned yarn centralized guiding device for textile machinery, a pulley is provided at the lower end of the lower slider, and the pulley is in rolling contact with the chute.

[0010] In the above-mentioned yarn centralized guiding device for textile machinery, a movable groove is formed in the inner top wall of the upper chute. A positioning plate is provided in the movable groove. A plurality of longitudinally and uniformly spaced positioning card slots are formed at the lower end of the positioning plate.

[0011] In the above-mentioned yarn centralized guiding device for textile machinery, a movable cavity is formed at the upper end of the thread passing block and at the corresponding position of the slider. A push plate is horizontally inserted at the left end of the thread passing block. The right end of the push plate extends into the movable cavity and is fixedly connected with the right inner wall of the movable cavity by a second spring.

[0017] 1. In the present invention, by providing a lifting cavity, a third spring, a lifting rod, a lifting plate, and a third wire loop, during the centralized guiding work of the yarn, when the tension of any one yarn is insufficient, the third spring contracts, driving the lifting rod to move upward. Subsequently, the third wire loop pulls the yarn with insufficient tension upward to bend, compensating for the lost tension and enabling it to continue being transported while maintaining a taut state.

[0018] 2. When the tension of any one yarn is insufficient in the present invention, the third wire loop moves upward to supplement the tension. At the same time, the lifting rod can drive the lifting block to move upward, and the amount of upward movement represents the magnitude of the tension loss. Therefore, the corresponding button will be pressed to light up the corresponding indicator light, thereby reminding the operator which yarn is loose and the degree of looseness, so as to facilitate timely processing to restore the tension.

Specific implementation manner

[0025] The following embodiments are only for illustrative purposes and are not intended to limit the scope of the present invention.

[0026] Embodiment

[0027] Referring to Figures 1-5 , a yarn centralized guiding device for textile machinery, includes a workbench 1. The left and right sides of the upper end of the workbench 1 are respectively fixedly connected with an incoming wire board 2 and a wire block 3. An installation opening 4 is opened at the front end of the wire block 3. A plurality of wire threading blocks 5 are arranged in the installation opening 4. A wire threading opening is horizontally opened at the center position of the wire threading block 5 for passing through the textile yarns to be centralized. Sliding grooves 6 are longitudinally opened on the upper and lower inner walls of the installation opening 4. Sliders 7, whose one ends are slidably connected in the corresponding sliding grooves 6, are fixedly connected to the upper and lower ends of each wire threading block 5, so that the wire threading block 5 can longitudinally move in the installation opening 4. A pulley is arranged at the lower end of the slider 7 located below, and the pulley is in rolling contact with the sliding groove 6 to facilitate better movement. The number of wire threading blocks 5 is determined according to the number of yarns to be used.

[0028] On the inner top wall of the upper chute 6, there is an activity groove 8. Inside the activity groove 8, there is a positioning plate 9. At the lower end of the positioning plate 9, there are a plurality of positioning card slots 10 arranged longitudinally and evenly spaced. At the upper end of each slider 7 located above, there is a telescopic groove 11. Inside the telescopic groove 11, there is a positioning card block 12 slidably connected. The upper end of the positioning card block 12 is inserted into one of the positioning card slots 10. Between the lower end of the positioning card block 12 and the inner bottom wall of the telescopic groove 11, there is a first spring 13 fixedly connected. At the upper end of the wire threading block 5 and at the corresponding position of the slider 7, there is an activity cavity 14. Horizontally inserted into the left end of the wire threading block 5 is a push plate 15. The right end of the push plate 15 extends into the activity cavity 14 and is fixedly connected with a second spring 17 between the right inner wall of the activity cavity 14. At the upper end of the push plate 15 and inside the activity cavity 14, there is a trapezoidal block 16 with a left-side inclined surface fixedly connected. At the lower end of the positioning card block 12, there is a vertical rod 18 fixedly connected. The lower end of the vertical rod 18 penetrates through the inner bottom wall of the telescopic groove 11 and extends into the activity cavity 14. The lower end of the vertical rod 18 is in sliding contact with the inclined surface on the trapezoidal block 16. The elastic force of the second spring 17 is greater than that of the first spring 13. Under the condition of no external force, the second spring 17 maintains its original length. At this time, the lower end of the vertical rod 18 contacts the uppermost end of the trapezoidal block 16. The positioning card block 12 is pushed out of the telescopic groove 11 and is clamped into the corresponding positioning card slot 10. Subsequently, the position of the wire threading block 5 cannot move and remains in a fixed state. When the corresponding push plate 15 is pushed, the second spring 17 can be pressed, so that the trapezoidal block 16 moves to the right. The vertical rod 18 stably moves downward under the action of the first spring 13, so that the positioning card block 12 is received into the telescopic groove 11, and thus the corresponding wire threading block 5 can be moved, facilitating the fine adjustment of the position of the wire threading block 5, changing the interval between the wire threading blocks 5, or adding wire threading blocks 5, so as to better conduct the guiding work of the yarn.

[0029] At the upper end of the positioning plate 9, there is a threaded rod 19 rotatably connected. The upper end of the threaded rod 19 is threadedly penetrated through the inner top wall of the activity groove 8 and is fixedly sleeved with a rotating block 20. By rotating the threaded rod 19 through the rotating block 20, the position height of the positioning plate 9 can be adjusted, so as to play the role of fixing the wire threading block 5. When the positioning plate 9 moves upward, some wire threading blocks 5 can be directly released, and thus the replacement and maintenance work of the wire threading blocks 5 can be directly carried out.

[0030] On the upper end of the workbench 1 and at the position between the wire inlet plate 2 and the wire guiding block 3, there is a top block 21 whose top view is an isosceles trapezoid fixedly connected. At the lower end of the top block 21 and at the position close to the wire inlet plate 2, there are a plurality of first wire guiding rings 22 fixedly connected. The first wire guiding rings 22 correspond to the wire threading ports. At the lower end of the top block 21 and at the position close to the wire guiding block 3, there is a second wire guiding ring 23 for the wire guiding work of the yarn.

[0031] Inside the top block 21, there are vertically provided a plurality of lifting cavities 24 which are evenly distributed longitudinally. A lifting plate 25 is slidably connected inside the lifting cavity 24. A third spring 28 is fixedly connected between the lifting plate 25 and the inner top wall of the lifting cavity 24. A lifting rod 26 is vertically and fixedly penetrated through the center position of the lifting plate 25. The lower end of the lifting rod 26 penetrates through the inner bottom wall of the lifting cavity 24 and is fixedly connected with a third wire ring 27. The diameter of the second wire ring 23 is larger than that of the first wire ring 22 and the third wire ring 27. The number of the lifting cavities 24 and the first wire rings 22 is the same as that of the threading blocks 5. The yarn passes through the corresponding threading blocks 5, the first wire rings 22 and the third wire rings 27 and then jointly passes through the second wire ring 23, and finally passes through the wire block 3 and is connected with the rope twisting device. The rope twisting device is a prior art and will not be described herein.

[0032] The third spring 28 can be kept in a stretched state under the tension of the yarn. When the tension is insufficient, the third spring 28 contracts, driving the lifting rod 26 to move upward. Then, the third wire ring 27 pulls the yarn with insufficient tension, bends upward, supplements the lost tension, and enables it to continue to be conveyed in a taut state.

[0033] At the upper end of the top block 21 and at the corresponding positions of each lifting cavity 24, an indicating block 29 is fixedly connected. An upward opening 30 is vertically provided on the indicating block 29. The upper end of the lifting rod 26 penetrates through the inner top wall of the lifting cavity 24 and extends into the upward opening 30. The upper end of the lifting rod 26 is fixedly connected with a lifting block 31. The lifting block 31 is in sliding contact with the inner wall of the upward opening 30. Three indicator lights 32 are provided on one side of each indicating block 29. Three buttons 33 which are arranged at intervals up and down are provided on the inner wall of the upward opening 30 close to the indicator lights 32. Each button 33 is electrically connected with the corresponding indicator light 32. The colors of the three indicator lights 32 on the same indicating block 29 are red, yellow, and green from top to bottom in sequence. When the tension of any one yarn is insufficient, the third wire ring 27 moves upward to supplement the tension. At the same time, the lifting rod 26 can drive the lifting block 31 to move upward. The amount of upward movement represents the magnitude of the tension loss. Therefore, the corresponding button 33 will be pressed to light the corresponding indicator light 32. Thus, it reminds the worker which yarn is loose and the degree of looseness, so as to facilitate timely treatment to restore the tension.

[0034] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
