Description

Technical Field

[0001] This utility model relates to textile equipment parts, and more particularly to a yarn guiding device. Background Technology

[0002] In modern textile equipment, device design is developing towards higher precision and intelligence, significantly improving the automation level and reliability of textile production. In textile equipment, the yarn guide device (or yarn guide disc, thread guide disc) is a key component, mainly used for guiding, tension control, and uniform distribution of yarns (yarn, chemical fibers, etc.). When textile equipment malfunctions, the yarns are prone to tangling on the yarn guide disc of the yarn guide device.

[0003] In existing technologies, when equipment malfunctions, the wire gets tangled in the wire guide plate of the wire guide device. Even with a detection and control device, it can only be detected when the accumulated wire reaches a certain thickness, causing the motor to stop rotating. Then, manual operation is required to handle the fault, resulting in additional waste wire accumulation and material waste, prolonging the downtime and increasing cost.

[0004] In order to overcome the above-mentioned defects of the existing technology, there is an urgent need in the field for a yarn guiding device that can sense when a small amount of yarn is wrapped and accumulated on the side wall of the yarn guiding disc, thereby triggering the motor of the yarn guiding device to stop rotating, reducing waste and material waste, shortening downtime, reducing costs and improving textile production efficiency. Utility Model Content

[0005] The following provides a brief overview of one or more aspects to offer a basic understanding of them. This overview is not an exhaustive summary of all conceived aspects, nor is it intended to identify key or decisive elements of all aspects, nor to define the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form to prepare for the more detailed descriptions that follow.

[0006] To overcome the aforementioned defects in the prior art, this utility model provides a yarn guiding device for textile equipment, including a motor, a yarn guiding disc, a control unit electrically connected to the motor, and an elastic lever. The motor drives the yarn guiding disc to rotate. The elastic lever is positioned such that when the yarn is wound on the yarn guiding disc, the yarn accumulates on the side wall of the yarn guiding disc, causing the elastic lever to move. The movement of the elastic lever triggers the control unit to stop the motor from working, thereby stopping the rotation of the yarn guiding disc.

[0007] In one embodiment, preferably, the wire guide device provided by the present invention further includes a deflector block connected to the elastic paddle. The deflector block is positioned such that when the wire is wound on the wire guide disc, the wire accumulates on the side wall of the wire guide disc to abut against the deflector block, causing the deflector block to move outward along the radial direction of the wire guide disc, thereby driving the elastic paddle to move.

[0008] In one embodiment, preferably, the actuating block has a contact surface that is close to the sidewall of the guide wire disc, and the contact surface is parallel to the axis of the guide wire disc.

[0009] In one embodiment, more preferably, the distance between the contact surface of the actuating block and the sidewall of the guide wire disc does not exceed 2 mm.

[0010] In one embodiment, preferably, the wire guide device provided by the present invention further includes a mounting frame, which includes a collar portion and a mounting portion. The collar portion is connected to the mounting portion, and the collar portion is used to fit the mounting frame onto the outer periphery of the motor. The mounting portion extends radially outward from the collar portion to form a mounting portion, and the mounting portion is used to mount the control unit.

[0011] In one embodiment, preferably, the guide wire device provided by the present invention may further include a protective shell disposed on the mounting bracket, and a cavity is formed between the protective shell and the mounting bracket to accommodate at least a portion of both the control unit and the elastic lever, with one end of the elastic lever extending out of the cavity.

[0012] In one embodiment, optionally, the circuit switch is located on the power supply circuit of the motor, and the movement of the elastic lever triggers the circuit switch to cut off the power supply to the power supply circuit.

[0013] In one embodiment, the control unit optionally includes a micro switch and a controller connected in communication. The movement of the elastic paddle triggers the micro switch to send an electrical signal to the controller, which then controls the motor to stop working.

[0014] In one embodiment, the control unit optionally includes a sensor and a controller connected in communication, the sensor sending an electrical signal to the controller when it detects movement of the elastic paddle, the controller controlling the motor to stop working.

[0015] Another aspect of this utility model provides a textile device including the yarn guiding device described in any of the above claims. Through ingenious design of its structure, this yarn guiding device allows a small amount of yarn to become entangled on the yarn guiding disc. The accumulated yarn on the side wall of the disc causes the elastic lever to move, and the control unit, triggered by the slight movement of the elastic lever, stops the motor and the yarn guiding disc from rotating. This reduces waste and material waste, shortens downtime, lowers costs, and improves textile production efficiency. Attached Figure Description

To provide a deep understanding of this utility model, many specific details will be included in the following description. This utility model may also be implemented without using these details. Furthermore, to avoid confusion or obscuring the focus of this utility model, some specific details will be omitted in the description.

[0056] 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.

[0058] It is understood that although terms such as "first," "second," and "third" may be used herein to describe various components, regions, layers, and / or parts, these components, regions, layers, and / or parts should not be limited by these terms, and these terms are only used to distinguish different components, regions, layers, and / or parts. Therefore, the first component, region, layer, and / or part discussed below may be referred to as the second component, region, layer, and / or part without departing from some embodiments of this utility model.

[0059] In order to overcome the above-mentioned defects in the existing technology, this utility model provides a yarn guiding device that can sense when a small amount of yarn accumulates on the side wall of the yarn guiding disc, thereby triggering the motor of the yarn guiding device to stop working and the yarn guiding disc to stop rotating, thereby reducing waste and material waste, shortening downtime, reducing costs and improving textile production efficiency.

[0060] The yarn guiding device of the textile equipment provided by this utility model may include a motor, a yarn guiding disc, a control unit electrically connected to the motor, and an elastic lever. The motor drives the yarn guiding disc to rotate. The elastic lever is positioned such that when the yarn is wound on the yarn guiding disc, the yarn accumulates on the side wall of the yarn guiding disc, causing the elastic lever to move. The movement of the elastic lever triggers the control unit to control the motor to stop working, thereby stopping the rotation of the yarn guiding disc.

[0061] In a preferred embodiment, the wire guide device provided by this utility model may further include a deflector block connected to the elastic lever. The deflector block is positioned such that when the wire is wound on the wire guide disc, the wire accumulates on the side wall of the wire guide disc to abut against the deflector block, causing the deflector block to move outward along the radial direction of the wire guide disc, thereby driving the elastic lever to move. A detailed description follows with reference to the accompanying drawings.

[0062] Figure 1 This is a schematic diagram of the guide wire device according to an embodiment of the present invention.

[0063] Please refer to Figure 1 In this embodiment, the wire guiding device 100 provided by the present invention includes a motor 101, a wire guiding disk 102, a toggle block 103, and a control unit 104 electrically connected to the motor. The motor 101 drives the wire guiding disk 102 to rotate. The control unit 104 is provided with an elastic toggle 105, which is connected to the toggle block 103. The position of the toggle block 103 is configured such that when the wire is wound on the wire guiding disk 102, the wire accumulates on the side wall 107 of the wire guiding disk 102, abuts against the toggle block 103 and moves outward along the radial direction of the wire guiding disk 102, thereby causing the elastic toggle 105 to move and triggering the control unit 104 to control the motor 101 to stop working, so that the wire guiding disk 102 stops rotating.

[0064] In a preferred embodiment, such as Figure 1 As shown, in the wire guiding device 100 provided by this utility model, the actuating block 103 is mounted close to the side wall 107 of the wire guiding disk 102, so that after the wire is wound around the side wall 107 of the wire guiding disk 102, it abuts against the actuating block 103 and moves outward along the radial direction of the wire guiding disk 102.

[0065] Understandable, Figure 1 In the illustrated embodiment, when the equipment malfunctions, the wire gets tangled on the side wall 107 of the wire guide disc 102. As the wire accumulates and reaches a certain thickness, it presses against the actuating block 103, exerting pressure and downward thrust on it. This causes the elastic actuating plate 105 to move downward. The control unit 104 is triggered by the movement of the elastic actuating plate 105 to stop the motor 101 from working, so that the wire guide disc 102 stops rotating, thereby reducing the generation of waste wire.

[0066] Figure 2A , Figure 2B This is a schematic diagram of the device structure of the guide wire device at different angles of the actuating block structure, according to an embodiment of the present invention.

[0067] Please refer to Figure 2A , Figure 2B You can also refer to the following: Figure 1 In a preferred embodiment of the present invention, the actuating block 200 is provided with a contact surface 201 to be close to the side wall of the guide wire disc, and the contact surface 201 is parallel to the axis of the guide wire disc.

[0068] More specifically, such as Figure 2B As shown, the mounting surface of the actuating block 200 is provided with a mounting hole 202 for mounting a flexible paddle. The flexible paddle is inserted into the mounting hole 202.

[0069] Understandably, the actuating block is a preferred embodiment of this invention as it better responds to wire tangling and accumulation on the wire guide disc. In fact, using only an elastic lever is also sufficient to respond to wire tangling and accumulation issues on the wire guide disc. The actuating block more stably converts wire tangling and accumulation into the movement of the elastic lever.

[0070] It should be noted that the shape and structure of the actuating block described here are merely illustrative examples and are not intended to limit the scope of protection of this utility model. Other structures that can achieve similar effects can be applied to the wire guide device provided by this utility model and should also be included within the scope of protection of this utility model.

[0071] Figure 3 This is a side view of the device structure of a guide wire device according to an embodiment of the present invention.

[0072] You can refer to the following: Figure 3 In a more preferred embodiment of the present invention, the distance between the contact surface 308 of the actuating block 305 and the side wall 309 of the guide wire disc 306 does not exceed 2mm.

[0073] Understandably, the design of the contact surface 308 of the actuating block 305 makes the position of the actuating block 305 more stable, while the appropriate spacing makes the device structure more sensitive and effective in responding to faults caused by the accumulation of tangled threads. The specific values ​​of the spacing here are only illustrative examples; in practical applications, they can be adjusted according to the type of equipment and the type of textile thread to adapt to the usage requirements of different scenarios.

[0074] Compared to some existing motor braking schemes that require a large amount of yarn to accumulate before the actuating block can move and the motor can stop, the yarn guiding device provided by this utility model, through the ingenious design of the actuating block structure and position, can promptly and accurately detect faults and abnormalities when a small amount of yarn begins to accumulate and become entangled. This allows for more timely fault detection, reduces waste generation, shortens equipment downtime, and improves the production efficiency of textile equipment.

[0075] Please continue to refer to this. Figure 1 In a preferred embodiment of the present invention, the wire guide device provided by the present invention further includes a mounting bracket 106 for mounting a control unit.

[0076] Figure 4 This is a schematic diagram of the mounting bracket in a wire guide device according to an embodiment of the present invention.

[0077] Please refer to the reference. Figure 4 and Figure 1 ,like Figure 1 As shown, in one embodiment, the mounting bracket 106 is fitted around the outer periphery of the motor 101. Figure 4 As shown, the mounting bracket 106 includes a collar portion 1062 and a mounting portion 1061 connected to each other. The collar portion 1062 is used to fit the mounting bracket onto the outer periphery of the motor. The mounting portion 1061 extends radially outward from the collar portion 1062 to form the mounting portion 1061, which is used to mount the control unit.

[0078] It should be noted that the assembly method of the control unit is only an exemplary description, intended to clearly illustrate the device structure in the preferred embodiment provided by this utility model, and not to limit the protection scope of this utility model. In actual applications, the control unit can also adopt other similar assembly forms, and the mounting bracket can also be other structures and assembly methods. Device structures that can perform similar functions can be applied to the wire guide device provided by this utility model, and should also be included within the protection scope of this utility model.

[0079] You can refer to the following: Figure 3 ,like Figure 3 As shown, in one embodiment, more preferably, the control unit 301 is fixedly mounted on the mounting part 302, the elastic lever 303 extends along the output side of the motor 304 to connect the toggle block 305, and the control unit 301 is also electrically connected to the motor 304 through the wiring harness 307.

[0080] Preferably, in one embodiment, the wire guide device provided by the present invention further includes a protective shell, which is disposed on the mounting bracket, and a cavity is formed between the protective shell and the mounting bracket to accommodate at least a portion of the control unit and the elastic lever, with one end of the elastic lever extending out of the cavity.

[0081] Figure 5 This is a schematic diagram of the device structure after the guide wire device is fitted with a protective shell, according to an embodiment of the present invention.

[0082] exist Figure 5 In the illustrated embodiment, the wire guide device provided by this utility model further includes a protective shell 501. The protective shell 501 is disposed on the mounting bracket 502 and covers the outside of the control unit 503, forming a cavity 505 with the mounting bracket 502. Parts of the control unit 503 and the elastic lever 504 are located in the cavity 505, thereby protecting the connection between the control unit 503 and the elastic lever 504.

[0083] In the wire guide device provided by this utility model, the control unit can be a circuit switch or a sensor. Understandably, since the control unit is triggered by the slight movement of the elastic lever, it has high sensitivity. Adding a protective shell to the outside of the control unit can prevent it from being falsely triggered by other interferences, and also effectively protects the connection between the control unit and the elastic lever, making the device structure more reliable.

[0084] The control unit in this utility model will now be described in detail.

[0085] In an optional embodiment, in the wire guide device provided by the present invention, the control unit is a circuit switch, which is located on the power supply circuit of the motor. The movement of the elastic lever triggers the circuit switch to cut off the power supply to the power supply circuit.

[0086] In another optional embodiment, the wire guide device provided by this invention includes a control unit comprising a microswitch and a controller connected in communication. The movement of the elastic lever triggers the microswitch to send an electrical signal to the controller, thereby controlling the motor to stop operating. (See reference...) Figure 6 .

[0087] Figure 6 This is a schematic diagram illustrating the structure of a wire guide device controlled by a micro switch and a controller according to an embodiment of the present invention.

[0088] exist Figure 6In the illustrated embodiment, the control unit of the wire guide device 600 includes a controller 601 integrated at the motor and a micro switch 602. The micro switch 602 is triggered by a slight movement of the elastic paddle 603 to send an electrical signal to the controller 601, thereby controlling the motor to stop working.

[0089] In another alternative embodiment, the control unit includes a sensor and a controller with communicative connectivity. The sensor sends an electrical signal to the controller when it detects movement of the resilient paddle, and the controller then stops the motor. The controller can be integrated into the motor.

[0090] For example in Figure 6 In the illustrated embodiment, the micro switch 602 can also be replaced by a sensor, which sends an electrical signal to the motor controller when the sensor detects that the elastic lever is moving, and the controller controls the motor to stop working.

[0091] Furthermore, the sensor can be a photoelectric sensor or an infrared sensor, capable of detecting movement of the elastic lever and sending an electrical signal to the motor controller, thereby controlling the motor to stop working. Understandably, the sensor's detection can be more sensitive, allowing the motor to stop working and the guide disc to cease rotation as soon as a small amount of wire begins to accumulate and press against the elastic lever, further reducing waste and shortening downtime.

[0092] The type of control unit described herein is merely illustrative, intended to clearly illustrate the working principle of the wire guide device provided by this utility model. A small accumulation of wire winding on the wire guide disc causes the elastic lever to move, and the movement of the elastic lever triggers the control unit to stop the motor. This is not intended to limit the scope of protection of this utility model. Other control unit types that can perform similar functions can be applied to the wire guide device provided by this utility model and should also be included within the scope of protection of this utility model.

[0093] Another aspect of this utility model provides a textile device including the yarn guiding device described in any of the above claims. Through a clever design of its structure, this yarn guiding device ensures that when yarn entangles on the yarn guide disc and accumulates on its side wall, an elastic lever is activated, triggering the control unit to stop the motor, thereby stopping the yarn guide disc from rotating.

[0094] For example, the textile equipment can be a high-speed texturing machine. During the texturing process of chemical fibers, the yarn is prone to breakage due to high-speed movement. The yarn guiding device provided by this utility model can achieve rapid yarn splicing. Alternatively, the textile equipment can be a winding machine. When misalignment occurs, the yarn guiding device, in conjunction with an electronic yarn clearer, removes the defect and rewinds the yarn.

[0095] These examples are intended to illustrate that the yarn guiding device provided by this utility model can be widely used in textile equipment, has a wide range of practical performance, can effectively reduce waste generation and material waste, shorten downtime, reduce costs and improve textile production efficiency.

[0096] The prior description of this disclosure is provided to enable any person skilled in the art to make or use this disclosure. Various modifications to this disclosure will be apparent to those skilled in the art, and the general principles defined herein may be applied to other variations without departing from the spirit or scope of this disclosure. Therefore, this disclosure is not intended to be limited to the examples and designs described herein, but should be accorded the widest scope consistent with the principles and novel features disclosed herein.
