Technical Field

[0001] The utility model relates to textile equipment, in particular to a self-adaptive tension regulating structure of a covered yarn machine. Background Art

[0002] Covered yarn, also known as wrapped yarn, is a new type of yarn structure. It uses filament or staple fiber as the yarn core, and is wrapped with another type of filament or staple fiber yarn. The outer yarn wraps the core yarn in a spiral manner. It has the advantages of uniform yarn length, fullness, smooth yarn with less hairiness, high strength and less breakage.

[0003] Among them, when the covering yarn machine covers the yarn core, the originally adjusted yarn core tension is affected due to the vibration of the mechanical device and other reasons, causing the yarn to be too loose or too tight, resulting in uneven covering. Utility Model Content

[0004] In order to solve the technical problem that after the tension adjustment of the existing yarn core is completed, the yarn is subjected to mechanical vibration, resulting in the yarn being too loose or too tight and uneven coating, the utility model provides an adaptive tension adjustment structure for a covering yarn machine, which has the advantage of being able to adaptively adjust the yarn core tension according to mechanical vibration.

[0005] The technical solution of the utility model is:

[0006] An adaptive tension adjustment structure for a coated yarn machine, comprising a frame and:

[0007] a slide, connected to the frame, wherein one end of the slide is L-shaped and has a through hole;

[0008] a sliding rod, slidably disposed in the through hole;

[0009] A support frame is provided on one end of the slide bar;

[0010] A spring is sleeved on the slide rod, with two ends of the spring respectively abutting against the support frame and the slide frame;

[0011] A guide wheel is rotatably mounted on the support frame, and the wheel surface of the guide wheel is a concave structure;

[0012] Wherein, when the yarn core of the covering yarn machine passes above the guide wheel, the spring is located below the support frame; when the yarn core of the covering yarn machine passes below the guide wheel, the spring is located above the support frame.

[0013] Optionally, both ends of the slide are L-shaped, and each end is provided with a through hole, and a sliding rod is slidably provided in each of the two through holes;

[0014] The two slide bars are arranged along the same straight line direction, and the ends of the two slide bars close to each other are respectively arranged at the top and bottom of the support frame, and a spring is respectively sleeved on the two slide bars.

[0015] Optionally, the support frame includes a connecting plate and two supporting plates arranged on the connecting plate, and the guide wheel is rotatably arranged between the two supporting plates;

[0016] The ends of the two sliding rods are respectively fixed on the top surface and the bottom surface of one end of the connecting plate.

[0017] Optionally, it also includes:

[0018] A guide rail is fixedly mounted on the frame, the slide is slidably mounted on the guide rail, and the slide rod is parallel to the guide rail;

[0019] an adjustment plate, disposed on a side of the slide, the adjustment plate having a threaded hole;

[0020] The screw rod matches the threaded hole on the adjustment plate, and two ends of the screw rod are rotatably arranged on the top and bottom of the frame respectively.

[0021] Optionally, the guide rails, slides, slide rods, support frames and springs are symmetrically arranged on the frame, and both ends of the adjustment plate are respectively connected to the two slides.

[0025] Optionally, the distance between the two ends of the slide is smaller than the sum of the lengths of the two slide rods.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] A slide rod is installed on the support frame, and the slide rod is slidably set in the through hole at the end of the slide frame. At the same time, a spring is set on the slide rod, and the position relationship between the slide frame and the support frame is adjusted by the spring. At the same time, the guide wheel is installed on the support frame.

[0028] During operation, the yarn core is passed around the guide wheel so that the yarn core passes through the concave wheel surface of the guide wheel. When the tension of the yarn core increases, the guide wheel and the support frame will be pulled. At this time, the guide wheel moves, which relieves the tension of the yarn core and also produces an extrusion effect on the spring. When the tension of the yarn core decreases, the spring drives the guide wheel and the support frame to move, generating a pulling force on the yarn core, thereby increasing the tension of the yarn core.

[0029] Through this technical solution, the change of yarn core tension can be adaptively responded to, so that the tension of the yarn core is within the reasonable required range, thereby avoiding the technical problem of uneven covering caused by the yarn being too loose or too tight.

[0033] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0034] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or reference letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides examples of various specific processes and materials, but a person of ordinary skill in the art will recognize the application of other processes and / or the use of other materials.

[0035] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0036] Example:

[0037] See also Figure 1 and Figure 2 An adaptive tension adjustment structure for a filament covering machine includes a frame, a carriage 1, a slide rod 2, a support frame 3, a spring 4, and a guide wheel 5. Specifically, the carriage 1 is connected to the frame. The end of the carriage 1 is L-shaped and has a through hole defined therein, with the axis of the through hole extending vertically. A slide rod 2 slides within the through hole, with its length extending vertically.

[0038] Among them, one end of the sliding rod 2 has a limit plate with a diameter larger than the diameter of the through hole, and the other end of the sliding rod 2 is fixedly set on the support frame 3. A guide wheel 5 is also rotatably set on the support frame 3. The wheel surface of the guide wheel 5 is a concave structure, and the rotation axis of the guide wheel 5 is on the horizontal plane.

[0039] In addition, the spring 4 is sleeved on the slide rod 2 , so that one end of the spring 4 abuts against the support frame 3 , and the other end abuts against the slide frame 1 .

[0040] When the yarn core is installed on the adjusting mechanism, if the yarn core passes over the top of the guide wheel 5, the spring 4 is located below the support frame 3 and the guide wheel 5 is located above the support frame 3. If the yarn core passes over the bottom of the guide wheel 5, the spring 4 is located above the support frame 3 and the guide wheel 5 is also located above the support frame 3.

[0041] When this embodiment is working, the yarn core is passed around the guide wheel 5 so that the yarn core passes through the concave wheel surface of the guide wheel 5. When the tension of the yarn core increases, the guide wheel 5 and the support frame 3 are pulled. At this time, the guide wheel 5 moves, which relieves the tension of the yarn core and also produces an squeezing effect on the spring 4. When the tension of the yarn core decreases, the spring 4 drives the guide wheel 5 and the support frame 3 to move, generating a pulling force on the yarn core, thereby increasing the tension of the yarn core.

[0042] Through this technical solution, the change of yarn core tension can be adaptively responded to, so that the tension of the yarn core is within the reasonable required range, thereby avoiding the technical problem of uneven covering caused by the yarn being too loose or too tight.

[0043] In one embodiment of the invention:

[0044] Both ends of the slide 1 are L-shaped, with a through hole provided at each end. A slide rod 2 slides through each through hole. The lengths of the two slide rods 2 are aligned, and the ends closest to each other are connected to the top and bottom of the support frame 3, respectively.

[0045] In addition, a spring 4 is respectively sleeved on the two slide bars 2. In addition, the spacing between the two ends of the slide 1 is less than the length of the two slide bars 2, so that the two ends of the slide 1 are respectively located in the middle of the two slide bars 2.

[0046] In this embodiment, by providing multiple springs 4, when the tension of the yarn core increases or decreases, the support frame 3 and the guide wheel 5 can be affected by the multiple springs 4, so that when the tension of the yarn core changes, the position of the support frame 3 changes and remains in the changed position.

[0047] Furthermore, the position of the support frame 3 can be changed in real time as the tension of the yarn core changes.

[0048] In another specific embodiment:

[0049] The support frame 3 includes a connecting plate and two supporting plates arranged on the connecting plate. The two supporting plates are parallel to each other on the connecting plate, and the supporting plate and the connecting plate are perpendicular to each other.

[0050] The guide wheel 5 is rotatably arranged between the two support plates, and the ends of the two slide rods 2 are respectively fixed on the top surface and the bottom surface of one end of the connecting plate.

[0051] A support plate and a connecting plate are provided to connect the slide bar 2 and the guide wheel 5 .

[0052] In another specific embodiment:

[0053] The adjustment structure further comprises a guide rail 6, an adjustment plate 7 and a screw rod 8. Specifically, the guide rail 6 is vertically arranged on the frame, the slide 1 is slidably arranged on the guide rail 6, and the length direction of the slide rod 2 is parallel to the length direction of the guide rail 6.

[0054] An adjustment plate 7 is fixed to the carriage 1, near its bottom. It has a threaded hole with its axis oriented vertically. A screw 8 fits within the threaded hole. The top and bottom ends of screw 8 are rotatably connected to the frame. A gap exists between the top of screw 8 and the horizontal plane of the bottom of guide wheel 5.

[0055] In this embodiment, by rotating the screw 8, the position of the adjustment plate 7 is driven to change, thereby driving the position change of the support frame 3 and the guide wheel 5, thereby adjusting the tension of the yarn core by the guide wheel 5 in the initial state, and then the subsequent adaptive adjustment of the tension can be within a reasonable range.

[0056] Preferably, to enhance the stability of the support frame 3 and guide wheel 5, the guide rail 6, carriage 1, slide rod 2, support frame 3, and spring 4 are symmetrically arranged. The ends of the adjustment plate 7 are connected to the two carriages 1. Furthermore, two slide rods 2 are provided at each end of the connecting plate, running along the same straight line. Each slide rod 2 is fitted with a spring 4.

[0057] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
