Description

Technical Field

[0001] This utility model relates to the technical field of texturing yarn production equipment, and in particular to a warp-break self-stopping slitting and warping device for texturing yarn production. Background Technology

[0002] In the production of textured yarn, the slitting warping machine is a crucial upstream piece of equipment. Its core function is to evenly arrange multiple textured yarns according to the required number, length, and tension, and then wind them into a warp beam. Because subsequent weaving processes demand extremely high consistency in warp tension and regularity of arrangement, directly using loose textured yarns for weaving would result in yarn entanglement and uneven tension, leading to fabric defects and even halting production. Through the slitting warping machine's combing and constant-tension winding, the textured yarns are ensured to form a structurally regular warp beam, providing qualified warp raw materials for subsequent weaving and guaranteeing fabric quality and production efficiency.

[0003] In existing applications of slitting and warping machines, the high-speed rotation of the large warping rollers creates a strong negative pressure field and generates mechanical entanglement force. This mechanical effect makes it extremely easy for clothing or limbs to become entangled and dragged by the rotating parts when people approach the equipment, ultimately leading to entanglement accidents. In the initial stage of an accident, some of the texturing yarns on the machine will break due to the entanglement and pulling force. However, current technology lacks an immediate shutdown trigger mechanism for such sudden accidents, allowing the equipment to continue operating. The unbroken texturing yarns can then cause secondary and multiple entanglements to the victim, further aggravating the severity of the injury. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a warp-break self-stopping slitting and warping device for the production of textured yarn.

[0006] Optionally, the protective mechanism includes a first guard rod and a second guard rod that block the warping roller. The first guard rod and the second guard rod are positioned vertically opposite each other. Both ends of the first guard rod are fixedly connected to a rotating frame. The rotating frame has a limiting groove. T-shaped clamping plates that are fixedly connected to the ends of the second guard rods are slidably connected inside the limiting grooves. A second spring is provided at the top of each limiting groove. One end of the second spring is fixedly connected to the inner wall of the limiting groove, and the other end of the second spring is fixedly connected to the corresponding T-shaped clamping plate. A spiral abutment rod that abuts against the rotating frame is spirally inserted into one of the T-shaped clamping plates.

[0007] Optionally, the stop triggering mechanism includes a rectangular slide groove formed on a U-shaped bracket, a U-shaped slide frame slidably connected inside the rectangular slide groove, two ends of the U-shaped slide frame being rotatably connected to corresponding rotating frames, a pair of inclined pull plates being fixedly connected to both ends of the U-shaped slide frame, and a pair of first springs corresponding to the inclined pull plates being fixedly connected to the outer wall of the end of the rotating frame near the U-shaped slide frame, and the ends of the first springs away from the rotating frame being fixedly connected to the corresponding inclined pull plates.

[0008] Optionally, the stop trigger mechanism further includes a contact sensor, which is fixedly connected to a slant plate on one of the U-shaped carriages. A switch button is provided on the bottom outer wall of the slitting and warping machine. An L-shaped bracket is fixedly connected to the outer wall of the slitting and warping machine.

[0009] Optionally, the lifting mechanism includes a protrusion fixedly connected to the middle of the U-shaped bracket, a multi-stage cylinder fixedly connected to the upper surface of the protrusion, a convex plate fixedly connected to the middle of the U-shaped slide, and the piston rod of the multi-stage cylinder fixedly connected to the convex plate.

[0010] Optionally, the pair of inclined plates and the first spring are symmetrically arranged with the connection end of the U-shaped carriage and the rotating frame as the center.

[0011] Optionally, both of the aforementioned rotating frames are symmetrically arranged with the first guard post and the second guard post as the center.

[0012] Optionally, the first guard post and the second guard post have the same cross-sectional diameter, and the first guard post and the second guard post have the same length.

[0013] In summary, this application includes at least one of the following beneficial technical effects: This invention utilizes a combination of protective mechanisms, a stop triggering mechanism, and a lifting mechanism. When in use, a multi-stage cylinder first moves the U-shaped slide, adjusting the height of the first and second guardrails to shield the warping roller.

The controller then activates the cylinder to press the switch button, stopping the slitting and warping machine. Simultaneously, the first spring acts as a buffer, ensuring the rotating frame automatically returns to its original position after a collision, preventing component damage, effectively preventing entanglement accidents and secondary injuries, and improving production safety.

Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiments or examples. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Example like Figures 1 to 3As shown, the warp breakage self-stop slitting and warping device for producing textured yarn proposed in this utility model includes a slitting and warping machine 1 and a large warping roller 11 mounted on the slitting and warping machine 1. The large warping roller 11 is a key component for achieving the winding of textured yarn during the slitting and warping process, and its high-speed rotation completes the regular winding operation of the warp yarn. A U-shaped bracket 2 is fixedly connected to the outer wall of the slitting and warping machine 1. The U-shaped bracket 2 provides a mounting support foundation for components such as the protective mechanism and the lifting mechanism, ensuring the stable operation of each mechanism. The bottom of the U-shaped bracket 2 is provided with a protective mechanism to block the large warping roller 11. The protective mechanism includes a first guard rod 6 and a second guard rod 7 that block the large warping roller 11. The first guard rod 6 and the second guard rod 7 are vertically opposite each other. Both ends of the first guard rod 6 are fixedly connected to a rotating frame 5. The rotating frame 5 carries the relevant components of the first guard rod 6 and the second guard rod 7 and can rotate when it is hit to trigger the stop trigger mechanism. The rotating frame 5 has a limiting groove 51. Inside the limiting groove 51, there is a T-shaped card plate 71 that is fixedly connected to the end of the second guard rod 7. The T-shaped card plate 71 is used to connect the second guard rod 7 and the rotating frame 5 to realize the position adjustment and fixation of the second guard rod 7.

[0023] Among them, such as Figures 1 to 3 As shown, each limiting groove 51 is equipped with a second spring 52 at its top. The second spring 52, in conjunction with the T-shaped clamping plate 71, enables elastic adjustment of the position of the second guard rod 7. One end of the second spring 52 is fixedly connected to the inner wall of the limiting groove 51, and the other end is fixedly connected to the corresponding T-shaped clamping plate 71. One of the T-shaped clamping plates 71 is screwed with a spiral abutment rod 72 that abuts against the rotating frame 5. When the spiral abutment rod 72 abuts against the rotating frame 5, it can fix the distance between the second guard rod 7 and the first guard rod 6, ensuring the stability of the protective mechanism structure. The pair of rotating frames 5 are symmetrically arranged with the first guard rod 6 and the second guard rod 7 as the center. The cross-sectional diameters of the first guard rod 6 and the second guard rod 7 are the same, and the lengths of the first guard rod 6 and the second guard rod 7 are the same.

[0024] In addition, such as Figures 1 to 3As shown, the protective mechanism is equipped with a stop trigger mechanism, which is activated after a collision. The stop trigger mechanism includes a rectangular slide groove 21 on the U-shaped bracket 2. The rectangular slide groove 21 provides sliding guidance for the U-shaped slide 3, ensuring that the U-shaped slide 3 can move smoothly up and down to adjust the position of the protective mechanism. The U-shaped slide 3 is slidably connected inside the rectangular slide groove 21. The U-shaped slide 3 supports the relevant components of the protective mechanism and, driven by the lifting mechanism, realizes the height adjustment of the protective mechanism. The two ends of the U-shaped slide 3 are rotatably connected to the corresponding rotating frame 5. A pair of inclined plates 32 are fixedly connected to both ends of the U-shaped slide 3. The inclined plates 32 are fixedly connected to the first spring 33 on one hand and are used to install the contact sensor 34 on the other hand, which can be triggered when the rotating frame 5 rotates. A pair of first springs 33 corresponding to the inclined plates 32 are fixedly connected to the outer wall of the rotating frame 5 near the U-shaped slide 3. The first springs 33 are normally in a taut state and are symmetrically arranged on both sides of the rotating frame 5, with the elastic force on both sides always balanced. When the end of the rotating frame 5 rotates, the pair of first springs 33 will automatically drive the rotating frame 5 to return to its initial position. The first springs 33 act as a buffer, ensuring that the rotating frame 5 can automatically return to its original position after a collision and rotation, thus preventing damage to the components. The ends of the first springs 33 away from the rotating frame 5 are fixedly connected to the corresponding inclined plates 32. The pair of inclined plates 32 and the first springs 33 are symmetrically arranged with the connection end of the U-shaped slide 3 and the rotating frame 5 as the center.

[0025] It is worth noting that, such as Figure 1 and Figure 2As shown, the shutdown trigger mechanism also includes a contact sensor 34. The contact sensor 34 is positioned within the rotating area of ​​the rotating frame 5 such that it can be pressed against the rotating frame 5 when it rotates. In the prior art, workers typically operate outside the first guardrail 6 and the second guardrail 7. Therefore, when a high-speed rotation of the warping roller 11 causes a entanglement accident, the worker is in a relatively safe area outside the guardrails. When the contact sensor 34 is triggered by the movement of the rotating frame 5, it sends a signal to the controller to initiate the shutdown process. The contact sensor 34 is a detection element that senses the presence, position, pressure, or state change of a target object through physical contact and converts it into a recognizable electrical signal. Its core function is to achieve accurate monitoring and signal feedback of the object's contact state. The contact sensor 34 is fixedly connected to the inclined plate 32 on one of the U-shaped slides 3. A switch button 8 is provided on the bottom outer wall of the slitting warping machine 1. An L-shaped bracket 9 is fixedly connected to the outer wall of the slitting warping machine 1. The L-shaped bracket 9 provides mounting support for the cylinder 10, ensuring that the cylinder 10 is stably fixed and that the piston rod is aligned with the switch button 8. A cylinder 10 is fixedly connected to the L-shaped bracket 9. The cylinder 10 starts after receiving a signal from the controller, and stops the slitting and warping machine 1 by pressing the switch button 8. The piston rod of the cylinder 10 moves through the L-shaped bracket 9 and aligns with the switch button 8. When the switch button 8 is pressed by the piston rod of the cylinder 10, the slitting and warping machine 1 is stopped. The cylinder 10 is electrically connected to the output of the controller, and the input of the controller is electrically connected to the contact sensor 34.

[0026] Furthermore, such as Figure 1 and Figure 2 As shown, a lifting mechanism that drives the protective mechanism to move up and down is installed on the U-shaped bracket 2. The lifting mechanism includes a protrusion 22 fixedly connected to the middle of the U-shaped bracket 2. The protrusion 22 provides a mounting carrier for the multi-stage cylinder 4, ensuring that the multi-stage cylinder 4 is stably fixed on the U-shaped bracket 2. The multi-stage cylinder 4 is fixedly connected to the upper surface of the protrusion 22. The multi-stage cylinder 4 provides driving force for the height adjustment of the protective mechanism and drives the U-shaped slide 3 to move up and down through extension and retraction. The multi-stage cylinder 4 is a reciprocating motion actuator that achieves different strokes and thrust outputs through the nested combination of multiple pistons (or plungers). It belongs to an important type of pneumatic or hydraulic actuator. Its core feature is the use of a piston cascade structure to adapt to diverse working conditions. A protruding plate 31 is fixedly connected to the middle of the U-shaped slide 3. The protruding plate 31 serves as a transmission component for the driving force of the multi-stage cylinder 4, driving the U-shaped slide 3 to move. The piston rod of the multi-stage cylinder 4 is fixedly connected to the protruding plate 31.

[0027] In this embodiment, when using the warp breakage self-stopping slitting and warping device for texturing yarn production, the position of the protective mechanism is first adjusted by the lifting mechanism, and the multi-stage cylinder 4 is started. Its piston rod pushes the convex plate 31, which drives the U-shaped slide 3 to slide in the rectangular slide groove 21 of the U-shaped support 2. Then, the rotating frame 5 and the first guard rod 6 and the second guard rod 7 move up and down accordingly, adjusting the protective mechanism to a suitable height that can effectively block the warping roller 11, thus protecting the personnel.

[0028] When clothing or limbs of personnel approach the warping roller 11 and touch the first guard bar 6 or the second guard bar 7, the protective mechanism is subjected to a collision force. If the collision force acts on the first guard bar 6 or the second guard bar 7, it will rotate around the connection end of the rotating frame 5 and the U-shaped slide 3. The movement of the rotating frame 5 will press against the contact sensor 34. When the contact sensor 34 triggers the preset sensing condition, it will transmit a signal to the controller. After receiving the signal, the controller controls the cylinder 10 to start. The piston rod of the cylinder 10 passes through the L-shaped bracket 9, aligns with and presses the switch button 8, realizing the immediate stop of the slitting warping machine 1, avoiding secondary and multiple entanglement injuries caused by continuous operation of the equipment.

[0029] Furthermore, the cooperation between the second spring 52 and the T-shaped clamp 71 within the limiting groove 51 ensures that the distance between the second guard rod 7 and the first guard rod 6 is adjustable. After adjustment, the second guard rod 7 only needs to have its spiral abutment 72 rotated. Since the spiral abutment 72 and the T-shaped clamp 71 are spirally connected, the end of the spiral abutment 72 tightly abuts against the rotating frame 5, thus fixing the distance between the second guard rod 7 and the first guard rod 6. When the fault is cleared, the multi-stage cylinder 4 can be controlled to reset, driving the protective mechanism back to its initial position. The first spring 33 will also drive the rotating frame 5 to return to its original state, and the contact sensor 34 will then disengage from the trigger state, allowing the equipment to restart production.

[0030] The preferred embodiments of this utility model described above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
