Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, specifically to a thread feeding mechanism for textile processing. Background Technology

[0002] Textiles are a process and industry involving the processing of fibers into yarns, and then weaving or knitting the yarns into fabrics. Commonly used raw materials include natural fibers and chemical fibers. The textile products manufactured are widely used in the fields of clothing, home textiles, and industrial textiles, and are essential products for modern life. Textiles require feeding the yarn to be woven into textile equipment. In order to ensure the efficiency and stability of the conveying, the yarn needs to be wound around the yarn feeding equipment to ensure sufficient friction and avoid slippage. However, this makes the threading work cumbersome, requiring manual winding inside the equipment, which is inefficient. Utility Model Content

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a thread feeding mechanism for textile processing, which has the following beneficial effects:

[0016] 1. By setting up a flipping component and a threading component, when it is necessary to thread the wire into the device, the flipping component drives the tension wheel to rotate upward, so that the tension wheel moves onto the driven wheel, and then fixes the wire inside the threading component. Then the threading component moves horizontally and pulls the wire to rest on the driving wheel and the driven wheel. Then the flipping component drives the tension wheel to rotate downward, so that the tension wheel moves between the driving wheel and the driven wheel, and squeezes the wire resting on it downward, so that the wire adheres to the lower part of the tension wheel. On the one hand, the wire is tightened, and on the other hand, the path of the wire is changed, so that the wire has a sufficient wrap angle with the driving wheel and the driven wheel, thus achieving the purpose of automatic threading.

By setting up a self-locking transmission component and a clutch transmission component, the clutch transmission component can transmit the power of the driven wheel's rotation to the self-locking transmission component after being energized, so that the self-locking transmission component drives the flipping component to achieve the purpose of flipping up and down. When the clutch transmission component is de-energized, it will not transmit to the self-locking transmission component. At this time, the self-locking transmission component uses the characteristics of its own mechanism to remain fixed and fix the flipping component, so that the flipping component can drive the tension wheel to a stable position.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-7A yarn feeding mechanism for textile processing includes a base 1, a housing 2 on the base 1, a drive wheel 10 and a driven wheel 12 rotatably mounted on the side of the housing 2, a pulley group 9 between the drive wheel 10 and the driven wheel 12, a drive motor 11 on the end face of the drive wheel 10, a flipping component 6 mounted on the shaft of the driven wheel 12, a tensioning wheel 4 rotatably mounted on the top of the flipping component 6, a flipping drive component 5 for driving the flipping component 6 to rotate on the other side of the driven wheel 12, a threading component 3 on the side of the housing 2, the threading component 3 being located between the tensioning wheel 4 and the driven wheel 12, and a transparent protective plate 8 on the base 1 located outside the drive wheel 10 and the driven wheel 12.

[0028] By setting up the flipping component 6 and the threading component 3, when the wire needs to be threaded into the equipment, the flipping component 6 drives the tension wheel 4 to rotate upward, so that the tension wheel 4 moves onto the driven wheel 12, and then fixes the wire inside the threading component 3. Then the threading component 3 moves horizontally and pulls the wire to rest on the driving wheel 10 and the driven wheel 12. Then the flipping component 6 drives the tension wheel 4 to rotate downward, so that the tension wheel 4 moves between the driving wheel 10 and the driven wheel 12, and squeezes the wire resting on it downward, so that the wire adheres to the lower part of the tension wheel 4. On the one hand, the wire is tightened, and on the other hand, the path of the wire is changed, so that the wire has a sufficient wrap angle with the driving wheel 10 and the driven wheel 12, achieving the purpose of automatic threading. In addition, the transparent protective plate 8 can protect the movement of the driving wheel 10 and the driven wheel 12, prevent personnel from accidentally touching them and causing mechanical injury, and its transparent characteristics can be used to observe the status of the wire conveying, which is convenient for technicians to manage.

[0029] The flipping component 6 includes a flipping frame 601 sleeved on the shaft of the driven wheel 12. The top end of the flipping frame 601 is connected to the tension wheel 4. The bottom end of the flipping frame 601 is provided with a gear ring 602 that meshes with the flipping drive component 5. The flipping frame 601 is provided with a second bearing seat 603. The second bearing seat 603 is provided with a linkage component 7 that is connected to the driven wheel 12 and the tension wheel 4.

[0030] By setting up a flipping frame 601 and a gear ring 602, the flipping frame 601 is sleeved on the shaft of the driven wheel 12. When the driven wheel 12 rotates, the flipping frame 601 is fixed and cannot rotate due to the meshing of the gear ring 602 with the flipping drive component 5. When the flipping drive component 5 drives the flipping frame 601 through the gear ring 602, the flipping frame 601 will drive the tension wheel 4 to rotate, thereby changing the position of the tension wheel 4 and facilitating the threading and tensioning work.

[0031] The linkage component 7 includes a third drive shaft 701 disposed in the second bearing housing 603. A second bevel gear set 702 is provided between one end of the third drive shaft 701 and the driven wheel 12, and a third bevel gear set 703 is provided between the other end of the third drive shaft 701 and the tension wheel 4.

[0032] By setting a third drive shaft 701, which is connected to the second bevel gear set 702 and the third bevel gear set 703, the third drive shaft 701 is positioned between the driven wheel 12 and the tension wheel 4, so that the tension wheel 4 can rotate synchronously with the driven wheel 12 in opposite directions. This allows the tension wheel 4 to use rotation to transport the thread, further improving the efficiency of thread transport.

[0033] The flipping drive component 5 includes a self-locking transmission assembly 501 that meshes with the gear ring 602. The self-locking transmission assembly 501 is provided with a clutch transmission assembly 502, and the top end of the clutch transmission assembly 502 is connected to the driven wheel 12 for transmission.

[0034] By setting up a self-locking transmission component 501 and a clutch transmission component 502, the clutch transmission component 502 can transmit the power of the driven wheel 12 to the self-locking transmission component 501 after being energized, so that the self-locking transmission component 501 drives the flipping component 6 to achieve the purpose of flipping up and down. When the clutch transmission component 502 is de-energized, it will not transmit to the self-locking transmission component 501. At this time, the self-locking transmission component 501 uses the characteristics of its own mechanism to remain fixed and fix the flipping component 6, so that the flipping component 6 can drive the tension wheel 4 to a stable position.

[0035] The self-locking transmission assembly 501 includes a first transmission shaft 5011 rotatably disposed inside the housing 2. One end of the first transmission shaft 5011 is provided with a transmission gear 5014 that meshes with the gear ring 602, and the other end is provided with a worm gear 5012. The side of the worm gear 5012 is meshed with a worm 5013 that is connected to the clutch transmission assembly 502.

[0036] By setting up a worm gear 5012 and a worm 5013, the worm gear 5012 and the worm 5013 mesh with each other, and their own structure has the characteristics of deceleration and self-locking. This means that only by relying on the drive of the clutch transmission component 502 can the first transmission shaft 5011 and the transmission gear 5014 be driven to rotate. This setting can ensure the stability of the tilting frame 601 and prevent the tilting frame 601 from being directly driven to rotate by the driven wheel 12.

[0037] The clutch transmission assembly 502 includes a first bearing seat 5021 disposed in the housing 2, a second transmission shaft 5022 disposed in the first bearing seat 5021, a first bevel gear set 5023 connected to the driven wheel 12 disposed at the top end of the second transmission shaft 5022, and an electromagnetic force coupler 5024 connected to the worm gear 5013 disposed at the bottom end of the second transmission shaft 5022.

[0038] By setting up an electromagnetic coupler 5024, which uses an electromagnet instead of the original permanent magnet, magnetic transmission coupling can only be generated when energized. When the tilting frame 601 needs to be driven, the power is transmitted from the driven wheel 12 through the energized coupling. When the tilting frame 601 does not need to be driven, the power is cut off, thus cutting off the transmission. It should also be noted that the power transmission method for the electromagnetic coupler 5024 includes, but is limited to, slip ring transmission and induction transmission.

[0039] The threading component 3 includes a linear motor 301 located on the side of the housing 2. The linear motor 301 is provided with a slide 302. The slide 302 is provided with a threading rod 303. The end face of the threading rod 303 is provided with a slot 304. A clip 305 is provided in the slot 304.

[0040] By setting a linear motor 301 and a threading rod 303, the linear motor 301 can drive the slide 302 to move horizontally and drive the threading rod 303 to move, so that the threading rod 303 can bring the thread into the driving wheel 10 and the driven wheel 12. The front end of the threading rod 303 is provided with a slot 304 and a clamping piece 305. When fixing, the thread can be put into the slot 304 and the clamping piece 305 can be used to clamp and fix the thread.

[0041] The pulley assembly 9 includes a first synchronous pulley 901 on the driving pulley 10 and a second synchronous pulley 903 on the driven pulley 12, with a synchronous belt 902 between the first synchronous pulley 901 and the second synchronous pulley 903;

[0042] By setting a synchronous belt 902, which has teeth that mesh with the first synchronous pulley 901 and the second synchronous pulley 903, power transmission can be carried out precisely, avoiding elastic slippage and generating excessive noise.

[0043] Working principle:

[0044] The thread is placed into the threading component 3, which then feeds the thread to the drive wheel 10 and the driven wheel 12. Subsequently, the drive motor 11 drives the driven wheel 12 to rotate through the drive wheel 10 and the pulley group 9. The driven wheel 12 then drives the flipping component 6 to rotate through the flipping drive component 5, causing the flipping component 6 to move the tensioning wheel 4 between the drive wheel 10 and the driven wheel 12. This allows the thread to pass through the drive wheel 10, the tensioning wheel 4, and the driven wheel 12 in a curved path, ensuring that the thread has sufficient wrap angle and achieving the purpose of fast threading. In addition, after the thread passes through the drive wheel 10, the tensioning wheel 4, and the driven wheel 12, the thread material can be dragged to tighten it and prevent the thread from slack.

[0045] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
