Description

Technical Field

[0001] The present invention relates to the technical field of yarn guiding structures, and particularly to a yarn guiding device based on automatic lubrication. Background Art

[0002] Yarns are products processed from various textile fibers into a certain fineness and are used for weaving, rope making, thread making, knitting, embroidery, etc. Yarns are divided into: ① staple fiber yarns, which are processed from staple fibers (natural staple fibers or cut chemical fibers) and are divided into ring-spun yarns, open-end spun yarns, self-twist yarns, etc. ② continuous filaments, such as natural silk and chemical fiber filaments, which are divided into twisted or untwisted, smooth filaments or textured filaments, etc. ③ combined yarns of staple fibers and continuous filaments, such as polyester-cotton filament core-spun yarns, etc. Threads are formed by combining two or more single yarns and twisting them together;

[0003] When the above various yarns are wound up, they are guided by a guiding device so that they can be stably wound up. The existing guiding device is driven by a reciprocating lead screw and a reciprocating block, which reciprocally drives the yarn to move back and forth. In order to improve the feel of the yarn, a lubrication module is also added for lubrication operations; and the existing lubrication module, tension control module, winding group and guiding device are all separately arranged on the side of the mechanism, which will cause a large occupied area of the frame; and the control of the components inside each module and device is separately arranged and used in combination, resulting in a high complexity in programming and a long programming time when replacing new products, affecting work efficiency; more driving parts will also increase the failure rate and cost of use.

[0015] Compared with the prior art, the beneficial effects that the present invention can achieve are as follows:

[0016] 1. By setting the driving mechanism and the guiding mechanism, the present invention can integrate the components for lubricating the yarn and controlling the tension at the guiding device, making the device more concentrated and reducing the occupied area. More winding groups can be arranged on the side of the same-volume frame for cooperation, increasing the winding efficiency of the yarn. Moreover, through multi-state driving control, the yarn can be stably guided and constrained, and when the yarn breaks, it can also be clamped and continue to be wound, facilitating the subsequent repair and wiring operations of the yarn.

[0017] 2. By setting the driving mechanism, the present invention can be used in a multi-state driving mode, adapting to various situations during yarn guiding, ensuring the stability during yarn guiding and triggering operations such as stable winding after the yarn breaks. And only one set of driving motors is needed to drive each component to rotate, reducing the continuous energy consumption of the device.

[0018] 3. By setting the matching block and its surrounding components, when the matching block is not squeezed by the triggering block, part of it is arranged inside the second gear, which can constrain the second gear, so that the second gear will not shift its position when rotating, playing a bearing effect. When the matching block is squeezed by the triggering block, it fits inside the second gear, enabling the second gear to drive the corresponding driving rod or movable frame to rotate. In this way, multiple driving states are generated to adapt to various subsequent situations, and the control logic is simple and the programming is not complex.

[0019] 4. By setting the guiding mechanism, using the supply of lubricating oil as the driving force, centralized lubrication and tension control can be carried out, adapting to the driving mechanism for auxiliary guiding, so that the yarn can be stably constrained and lubricated. Moreover, the lubricating oil can lubricate all internal components, reducing the wear rate of the components. Without the need for other driving parts, tension control and lubrication supply can be completed, the control logic is simple, reducing the programming complexity, making its movement more stable and reducing the error failure rate.

[0020] 5. In the present invention, by providing a restraint block and its peripheral components, when the slider slides inside the chute, the rotation between the guide block and the restraint rod can be limited. When the restraint rod is not driven, the guide block can drive the restraint rod to rotate cooperatively. When meeting the normal guide shaft, the restraint rod can actively drive the guide block to rotate when being driven, which can compensate for the insufficient traction of the yarn. The restraint block can extend the extrusion time of the plug block, so that the lubricating oil supply will not be interrupted. And when the slider passes through the corresponding connection cavity position, the lubricating oil can slightly overflow, producing a lubricating effect on the slider, reducing wear and providing a longer service life.

[0021] 6. In the present invention, by providing a movable column and its peripheral components, the movable column only needs to cooperate with the change of the lubricating oil pressure to change the distance it slides out inside the restraint cavity, forming a change in diameter, thereby changing the tension control of the yarn. And when the movable column slides, it can be lubricated by the lubricating oil, realizing the triggering of multiple effect controls by a single lubricating oil supply, without the need for redundant control components, reducing the equipment setting cost.

[0022] 7. In the present invention, by providing a first partition block and a second partition block and their peripheral components, when the first partition block and the second partition block are triggered, they can produce a restraint and block effect on the yarn at both sides of the liquid guide plate, keeping the yarn on the side of the liquid guide plate for lubricating and smearing. And subsequently, when the first partition block and the second partition block are triggered to approach, they can elastically clamp the yarn. Synchronously, the restraint rod actively drives the guide block to rotate for winding, avoiding the broken yarn from running around randomly.

[0023] 8. In the present invention, by providing a guiding groove and its peripheral components, the lubricating oil can slowly flow out through the guiding groove, enabling the other components to be triggered to slide by the lubricating oil pressure. And when the liquid guide plate resets, the guiding groove can still overflow the lubricating oil into the installation groove. When the liquid guide plate slides, it is pushed into the movable groove accordingly, meeting the lubrication requirements for the subsequent sliding of the liquid guide plate and the movable block, improving the utilization efficiency of the lubricating oil and avoiding waste.

[0038] As Figures 2 to 4 shown in the figure, the driving mechanism 3 includes a first gear 31 movably arranged on the side surface of the mounting frame 1. The first gear 31 is a circular gear. A micro-motor 311 is fixedly installed on the side surface of the first gear 31, and the micro-motor 311 is fixed on the side surface of the mounting frame 1 through a rectangular plate. Second gears 32 are symmetrically arranged on both sides of the first gear 31, and the second gears 32 are movably arranged on the side surface of the mounting frame 1. The second gear 32 is an annular gear with a concave cross-section. A toothed belt 33 is meshed and sleeved on the side surfaces of the second gear 32 and the first gear 31, and the toothed belt 33 is movably arranged on the side surface of the mounting frame 1. The toothed belt 33 is an "O"-shaped belt with teeth on its inner side. A driving rod 34 is arranged inside the mounting frame 1, and the driving rod 34 penetrates through the mounting frame 1 and is movably installed inside the second gear 32 at the upper position. The driving rod 34 is a reciprocating lead screw with threaded grooves staggered on its side surface. A movable frame 35 is movably sleeved on the side surface of the driving rod 34, and the movable frame 35 is slidably installed inside the rectangular groove on the inner side of the mounting frame 1. The movable frame 35 is a convex-shaped "C"-shaped frame. An arc-shaped block is rotatably installed inside the movable frame 35 and is movably arranged inside the threaded groove on the side surface of the driving rod 34. The movable frame 35 can be driven by the driving rod 34 to move reciprocally. A constraint rod 36 is arranged inside the mounting frame 1, and the constraint rod 36 penetrates through the movable frame 35 and the mounting frame 1 and is movably installed inside the second gear 32 at the lower position. The constraint rod 36 is a cylindrical rod; specifically, the micro-motor 311 drives the first gear 31 to rotate. Driven by the toothed belt 33, the two second gears 32 rotate synchronously. Combined with subsequent components, the driving rod 34 or the movable frame 35 can be selectively driven to rotate. The driving rod 34 can cooperate with the movable frame 35 to make it move reciprocally. The constraint rod 36 further constrains the movable frame 35;

[0039] The driving rod 34 and the movable frame 35 are respectively provided with an installation cavity 37 on the side corresponding to the second gear 32. The installation cavity 37 is a cylindrical cavity. An electric push rod 371 is fixedly installed on the wall surface of the installation cavity 37. A trigger block 372 is fixedly installed at the output end of the electric push rod 371, and the trigger block 372 is movably installed inside the installation cavity 37. The trigger block 372 is a cylindrical block with tapered sides on both sides. Corresponding to the center position of the second gear 32, a through activity cavity 38 is equidistantly opened on the wall surface of the installation cavity 37. The activity cavity 38 is a cross-shaped groove. A matching block 381 is movably installed inside the activity cavity 38, and both ends of the matching block 381 respectively extend to the inside of the installation cavity 37 and the inner side position of the second gear 32. The matching block 381 is a cross-shaped block made of elastic material. Symmetrically fixed to the side surface of the matching block 381 and the wall surface of the activity cavity 38 are first support blocks 382. The first support blocks 382 are elastic material blocks with a cross-section in a continuous "W" shape. Specifically, the electric push rod 371 can drive the trigger block 372 to move reciprocally. The trigger block 372 presses on the side surface of the matching block 381 to make it slide inside the activity cavity 38. The matching block 381 fits on the inner side of the second gear 32. At this time, the second gear 32 can drive the corresponding driving rod 34 or the movable frame 35 to perform synchronous rotational motion. On the contrary, when the trigger block 372 is not on the side surface of the matching block 381, under the elastic force of the first support block 382, the matching block 381 is reset. Part of the matching block 381 is arranged at the inner side position of the second gear 32 to restrict it. At this time, the second gear 32 will not drive the corresponding driving rod 34 or the movable frame 35 to perform rotational motion;

[0040] The guiding mechanism 4 provided can cooperate with the driving mechanism 3 to guide the yarn. While guiding, it can automatically lubricate the yarn, and when the yarn breaks, it can clamp the yarn and cooperate with the guiding mechanism 4 to wind up the broken yarn, which is convenient for subsequent maintenance operations by manual workers;

[0041] Such as Figures 5 to 10As shown in the figure, the guiding mechanism 4 includes a guiding block 41 movably sleeved on the side surface of the restraining rod 36, and the guiding block 41 is arranged inside the movable frame 35. The guiding block 41 is an annular block, and an inner cavity 411 is formed inside the guiding block 41. The inner cavity 411 is an annular cavity. A sliding groove 42 is formed on the side surface of the restraining rod 36. The sliding groove 42 is a rectangular groove. A sliding block 421 is movably installed inside the sliding groove 42, and the sliding block 421 is fixedly installed at the inner side position of the guiding block 41. The sliding block 421 is a rectangular block. A matching cavity 422 is formed at the lower side of the sliding block 421, penetrating through the sliding block 421 and the guiding block 41 to the inside of the inner cavity 411. The matching cavity 422 is a cylindrical cavity. A restraining block 423 is fixedly installed on the inner wall of the sliding block 421. The restraining block 423 is an arc-shaped block. A liquid guiding cavity 43 is formed on the side surface of the restraining rod 36 away from the second gear 32, and the liquid guiding cavity 43 is connected to a lubricating oil supply module through a rotatable pipeline. This module can supply lubricating oil and adjust the liquid supply pressure. The liquid guiding cavity 43 is a cylindrical groove. Connecting cavities 431 penetrating through the restraining rod 36 to the inside of the liquid guiding cavity 43 are equidistantly formed on the bottom wall of the sliding groove 42. The connecting cavities 431 are cylindrical grooves with a cross-section in the shape of a Chinese character 'tu'. A blocking block 432 is movably installed inside the connecting cavity 431. The blocking block 432 is a cylindrical block in the shape of a Chinese character 'tu' with a tapered upper side. A first spring 433 is fixedly connected between the side surface of the blocking block 432 and the wall surface of the connecting cavity 431. Specifically, by default, the restraining block 423 can elastically support the first spring 433 to make it fit against the wall surface of the connecting cavity 431, blocking and isolating the connecting cavity 431. The first spring 433 corresponding to the position of the sliding block 421 is pushed by the restraining block 423, and a part of the first spring 433 slides out of the inside of the connecting cavity 431. At this time, the connecting cavity 431 is in a linked state, and the supplied lubricating oil flows into the inside of the liquid guiding cavity 43, passes through the connecting cavity 431 and the matching cavity 422, and fills the inside of the inner cavity 411. When the movable frame 35 is driven by the driving rod 34 to move, the movable frame 35 drives the guiding block 41 to slide on the side surface of the restraining rod 36. Synchronously, the sliding block 421 slides inside the sliding groove 42 to generate a constraint on it. When the restraining rod 36 is not driven by the second gear 32, it can rotate in cooperation with the guiding block 41. When the restraining rod 36 is driven by the second gear 32, it can actively drive the guiding block 41 to perform a rotational motion;

[0042] The outer circumference of the guide block 41 is equidistantly provided with constraint cavities 44 in an array, the constraint cavity 44 is a convex cavity, a movable column 441 is movably installed inside the constraint cavity 44 and the movable column 441 is tightly fitted to the wall of the constraint cavity 44, the movable column 441 is an I-shaped block with a rubber ring on the side, and a second spring 442 is equidistantly fixedly connected between the side of the movable column 441 and the wall of the constraint cavity 44, a connecting groove 443 that penetrates the guide block 41 to the inside of the inner cavity 411 is opened on the bottom wall of the constraint cavity 44, and the connecting groove 443 is a funnel-shaped circular groove, and a mounting groove 45 is opened on the side of the movable column 441 away from the constraint rod 36, and the mounting groove 45 is A convex groove, a liquid guide plate 451 is movably installed inside the installation groove 45, and the liquid guide plate 451 is a convex block with inclined surfaces on both sides. A movable groove 46 is mirrored on the wall surfaces on both sides of the installation groove 45, and the movable groove 46 penetrates the guide block 41. The movable groove 46 is a convex groove, and a movable block 461 is movably installed inside the movable groove 46, and the movable block 461 partially extends to the side position of the guide block 41. The movable block 461 is an "L"-shaped block with an inclined surface on one side. A second support block 462 is symmetrically fixedly connected between the side of the movable block 461 and the wall surface of the movable groove 46, and the second support block 462 is an elastic material block with a continuous "W"-shaped cross section A first spacer 463 and a second spacer 464 are mirror-imaged on the side of the guide block 41 corresponding to the position of the movable block 461. The first spacer 463 is a rectangular block, and the second spacer 464 is an "L"-shaped block. The first spacer 463 and the second spacer 464 can be close to each other. Elastic rods 465 are symmetrically arranged on the sides away from the first spacer 463 and the second spacer 464, and the elastic rods 465 penetrate the movable block 461. The elastic rods 465 are composed of a "T"-shaped round rod and a spring. The first spacer 463 and the second spacer 464 are constrained by the "T"-shaped round rod, and the spring plays an elastic support to them. A through hole is opened on the bottom wall of the mounting groove 45. The slot 47 passing through the movable column 441 is a cylindrical slot with a cross section in the shape of a Chinese character "土". A movable rod 471 is movably installed inside the slot 47 and the movable rod 471 is fixedly installed at the lower side of the mounting slot 45. The movable rod 471 is a "T"-shaped round rod with a rubber ring on the side. A support tube 472 is fixedly connected between the side of the movable rod 471 and the wall of the slot 47 and the support tube 472 is movably sleeved on the side of the movable rod 471. The support tube 472 is a cylinder made of elastic material with a continuous "W"-shaped cross section. A guide groove 48 is opened on the lower side of the movable rod 471 to penetrate it and the mounting slot 45. The guide groove 48 is a cylindrical groove of more than one centimeter.Specifically, the lubricating oil inside the inner cavity 411 can be guided by the guiding groove 48 to flow to the side position of the installation groove 45 to lubricate the yarn, and the excess lubricating oil can perform appropriate lubrication operations on the remaining components. The lubricating oil under the synchronous belt pressure can first push the movable rod 471 to make the installation groove 45 slide to be flush with the side of the guiding block 41. The installation groove 45 squeezes and pushes the movable block 461 to move away from each other, so that the first partition block 463 and the second partition block 464 are arranged on both sides of the installation groove 45 to block and restrain the yarn. Then, the movable column 441 can continue to be pushed to slide inside the restraining cavity 44. By changing the oil pressure of the lubricating oil, the distance that the movable column 441 slides out of the restraining cavity 44 can be adjusted, so as to adjust the tension of the yarn on the side of the movable column 441. In addition, when the yarn breaks, the tension sensor detects that the yarn loses tension. At this time, the supply of the lubricating oil is stopped and it flows back. Under the elastic force of the second support block 462, the support cylinder 472 and the second spring 442, the movable column 441 and the installation groove 45 are reset, and the corresponding two groups of movable blocks 461 move closer to reset. At this time, the first partition block 463 and the second partition block 464 cooperate to clamp and restrain the yarn. The first partition block 463 and the second partition block 464 elastically clamp the yarn through the elastic support of the elastic rod 465. At this time, the constraint rod 36 is driven to rotate, and the guiding block 41 can wind up the broken yarn to prevent it from running around randomly.

[0043] Working principle:

[0044] During use: First, the lubricating oil supply module supplies lubricating oil to the inside of the liquid guiding cavity 43. The oil pressure of the lubricating oil pushes the movable rod 471 to make the installation groove 45 flush with the side of the guiding block 41. The movable groove 46 is pushed by the installation groove 45 to make the first partition block 463 and the second partition block 464 move away from each other to both sides of the installation groove 45. The yarn is arranged on the sides of the movable column 441 and the installation groove 45 and is tensioned by the guiding roller 2 arranged outside.

[0045] Then, the winding operation is performed at the rear end. At this time, the electric push rod 371 on the side of the driving rod 34 pushes the trigger block 372 to fit on the side of the mating block 381. The driving rod 34 is driven to rotate by the corresponding second gear 32, and the movable frame 35 is driven to move reciprocally. When the yarn is wound, it is guided by the traction force to rotate the guiding block 41. At this time, the constraint rod 36 is not driven by the second gear 32 and rotates adaptively with the guiding block 41. The yarn is stably guided. The lubricating oil discharged from the guiding groove 48 is smeared on the side of the yarn, and at the same time, appropriate lubrication operations are performed on the remaining components.

[0046] When the guiding block 41 slides on the side of the constraint rod 36, the slider 421 slides inside the chute 42 to constrain and guide it. The slider 421 slides inside the chute 42, and the blocking block 432 that the slider 421 can correspondingly squeeze and contact slides inside the connection cavity 431 to make it communicate. The constraint block 423 can keep the connection cavity 431 communicating continuously when the slider 421 passes through the position of the blocking block 432. On the contrary, under the elastic force of the first spring 433, the blocking block 432 resets to block the connection cavity 431. The lubricating oil overflowing from the connection cavity 431 during sliding can also lubricate the slider 421 to reduce the friction of the slider 421 sliding inside the chute 42;

[0047] Finally, by changing the oil pressure of the lubricating oil, the distance that the movable column 441 slides out of the constraint cavity 44 can be adjusted to adaptively adjust and control the tension of the yarn. And when the traction force of the yarn is insufficient, at this time, the trigger block 372 on the side of the constraint rod 36 fits against the side of the mating block 381. The constraint rod 36 is driven by the corresponding second gear 32, and the constraint rod 36 can actively drive the guiding block 41 to rotate, so as to compensate for the traction force on the yarn;

[0048] When the yarn breaks: When it is detected that the yarn loses tension, the lubricating oil supply module stops supplying lubricating oil, so that the lubricating oil can flow back. At this time, the slider 421 stops at the corresponding connection cavity 431 position, and the driving rod 34 switches to the state of not being driven by the second gear 32. Through the elastic force of the second support block 462 and the support cylinder 472, the movable rod 471 pulls the liquid guide plate 451 to slide into the installation groove 45. At the same time, the guiding groove 48 will overflow lubricating oil into the installation groove 45 for subsequent component sliding lubrication. The first partition block 463 and the second partition block 464 are driven by the movable block 461 to move closer to elastically clamp the yarn. The constraint rod 36 is driven by the corresponding second gear 32 to actively drive the guiding block 41 to rotate, and the yarn is wound up, which is convenient for subsequent yarn processing and avoids it running around randomly after breaking.

[0049] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to this. Various changes can be made without departing from the spirit of the present invention within the knowledge scope of those skilled in the art.
