Description

Technical Field

[0001] The utility model relates to the field of weft yarn frames, in particular to a weft yarn frame feeding structure. Background Art

[0002] The weft frame is a key component in textile machinery, mainly used to support and control the tension and position of the weft yarn. It ensures that the yarn enters the textile machine with appropriate tension and correct position through precise structural design, such as base, support rod and weft sleeve rod, thereby improving textile efficiency and product quality. The weft frame is widely used in various textile machinery, such as air-jet looms, warp knitting machines, etc. It is an indispensable part of the textile process. In the market, many textile machinery suppliers provide various types of weft frames to meet the needs of different customers. Its importance in the textile industry is self-evident.

[0003] Although the weft yarn frames currently in use are usually designed to facilitate the oblique placement of the weft yarns for ease of use, there is still a significant problem in actual use. Specifically, these weft yarn frames provide a relatively limited adjustment range for the placement angle of the weft yarns, and are often limited to one or fixed placement angle. In a variety of processing environments and conditions, this design limits the rapid adjustment of the weft yarn placement angle, thereby affecting the flexibility and convenience of the weft yarn frame. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a weft yarn frame feeding structure to solve the technical problem that the current weft yarn frame is limited in the placement angle of the weft yarn and is not convenient for quickly adjusting the placement angle of the weft yarn.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a weft yarn frame feeding structure, comprising a support rod, a support arm is arranged on the outer side of the support rod, an extension arm is arranged on the other end of the support arm, a placing rod is installed on the outer side of the extension arm through a mounting ring and a clamping seat, a clamping mechanism is arranged on the inner side of the mounting ring, the clamping mechanism comprises a fixed ring, a plurality of clamping grooves are provided on the outer side of the extension arm, three through grooves are provided on the surface of the fixed ring, clamping teeth are provided inside the through grooves, a rotating ring is provided on the outer side of the fixed ring, a groove is provided on the inner side of the rotating ring, and a magnetic ring is provided on the outer side of the rotating ring.

[0006] By adopting the above technical solution, the paddle can be turned to cause the rotating ring to rotate. This action causes the abutment force of the groove on the latch tooth to gradually weaken. At the same time, due to the magnetic adsorption between the magnetic ring and the latch tooth, the latch tooth can be smoothly detached from the latch groove, thereby unlocking the clamping seat and the placement rod. Subsequently, the angle of the clamping seat and the placement rod can be easily adjusted to the desired position. When the ideal angle is reached, the paddle is turned again to make the rotating ring rotate in the opposite direction. At this time, the groove will abut against the latch tooth again to ensure that the latch tooth is tightly combined with the corresponding latch groove, thereby completing the angle adjustment and locking of the placement rod.

[0007] Furthermore, a paddle is fixedly connected to one side of the rotating ring to provide a support point for the user to act on the rotating ring.

[0008] By adopting the above technical solution, the user can easily control the rotation of the rotating ring by turning the paddle without directly touching the rotating ring itself, thereby simplifying the operation process.

[0009] Furthermore, the material of the latching teeth is magnetic metal, the latching teeth are magnetically attracted to the magnetic ring, and the two sides of the rotating ring are in contact with the inner wall of the mounting ring to provide a rotational friction coefficient of the rotating ring.

[0010] By adopting the above technical solution, the latch tooth, as a magnetic metal, can produce a magnetic attraction with the magnetic ring, so that the latch tooth can be more stably and accurately aligned with and disengaged from the latch groove during the unlocking and locking process, thereby improving the reliability and efficiency of the operation.

[0011] Furthermore, the outer side surface of the latch tooth is an inclined structure, and the outer side surface of the latch tooth abuts against the inner wall of the groove.

[0012] By adopting the above technical solution, the latching teeth can be unlocked and locked more smoothly when subjected to the abutment force of the inner wall of the groove. This structure reduces the friction resistance between the latching teeth and the groove, making the operation easier.

[0013] Furthermore, the plurality of engaging grooves are arranged linearly and equidistantly along the central axis of the extension arm, and the engaging grooves are engaged with the engaging teeth.

[0014] By adopting the above technical solution, the equidistant linearly arranged snap-in grooves provide multiple fixed position options for adjusting the angle of the placement rod, which means that the user can accurately adjust the placement rod to any preset angle position according to actual needs, thereby meeting the needs of different weft yarn processing or installation.

[0015] Furthermore, the support arm is rotatably connected to the extension arm via a swivel joint, and the mounting ring and the extension arm are in a coaxial sleeve structure.

[0016] By adopting the above technical solution, the connection of the rotating joint, the support arm and the extension arm can rotate flexibly, which increases the freedom and adjustability of the weft rack. The user can easily adjust the angle of the extension arm to adapt to different working environments and needs.

[0017] Furthermore, a yarn guide rod is installed on the upper outer side of the support rod, a yarn guide plate is installed on the yarn guide rod, and a base is arranged at the bottom end of the support rod.

[0018] By adopting the above technical solution, the arrangement of the yarn guide rod and the yarn guide plate provides a clear guide for the weft yarn, helps to keep the weft yarn neat and orderly, reduces the confusion and entanglement of the weft yarn during the conveying process, and thus improves production efficiency.

[0019] In summary, the utility model mainly has the following beneficial effects:

[0020] The utility model can easily unlock the installation ring by toggling the paddle through the clamping mechanism. This is because the action of the paddle causes the rotating ring to rotate, thereby weakening the abutment force of the groove on the clamping tooth. At the same time, the magnetic adsorption effect of the magnetic ring and the clamping tooth causes the clamping tooth to disengage from the clamping groove, so that the clamping seat and the placement rod can rotate freely. When the placement rod is adjusted to a desired angle, the paddle is toggled again to cause the rotating ring to rotate in the opposite direction, the groove abuts against the clamping tooth again, and the clamping tooth is tightly combined with the corresponding clamping groove to complete the locking. This process simplifies the unlocking and locking operations of the installation ring, improves the convenience of adjusting the angle of the placement rod, and expands the adjustment range, so that the installation of the weft yarn can better adapt to changing environments and working conditions.

[0029] The following describes an embodiment of the utility model based on its overall structure.

[0030] Embodiment 1:

[0031] A weft frame feeding structure, such as Figure 1-Figure 4As shown, it includes a support rod 1, a support arm 201 is arranged on the outer side of the support rod 1, an extension arm 202 is arranged on the other end of the support arm 201, a placement rod 204 is installed on the outer side of the extension arm 202 through a mounting ring 203 and a clamping seat 6, a clamping mechanism 5 is arranged on the inner side of the mounting ring 203, and the clamping mechanism 5 includes a fixed ring 501, a plurality of clamping grooves 502 are provided on the outer side of the extension arm 202, three through grooves 503 are provided on the surface of the fixed ring 501, and latch teeth 504 are arranged inside the through grooves 503, a rotating ring 505 is arranged on the outer side of the fixed ring 501, a groove 506 is provided on the inner side of the rotating ring 505, and a magnetic ring 508 is arranged on the outer side of the rotating ring 505, and the rotating ring 505 can be caused to rotate by turning the paddle 507, and this action causes the abutment force of the groove 506 on the latch teeth 504 to gradually weaken. At the same time, due to the magnetic ring 508 Due to the magnetic attraction between the latch tooth 504, the latch tooth 504 can be smoothly disengaged from the latching groove 502, thereby unlocking the clamping seat 6 and the placement rod 204. Subsequently, the angle of the clamping seat 6 and the placement rod 204 can be easily adjusted to the desired position. When the ideal angle is reached, the paddle 507 is toggled again to make the rotating ring 505 rotate in the opposite direction. At this time, the groove 506 will re-engage the latch tooth 504 to ensure that the latch tooth 504 is tightly combined with the corresponding latching groove 502, thereby completing the angle adjustment and locking of the placement rod 204. The installation ring 203 can be quickly unlocked and locked by simply toggling the paddle 507. This not only improves the convenience of adjusting the angle of the placement rod 204, but also significantly expands the range of its angle adjustment. Therefore, this structure is conducive to improving the installation applicability of the weft yarn frame for different usage environments and working conditions.

[0032] See also Figure 3 , Figure 4 A paddle 507 is fixedly connected to one side of the rotating ring 505, which is used to provide a support point for the user to act on the rotating ring 505. The user can easily control the rotation of the rotating ring 505 by paddle 507 without directly touching the rotating ring 505 itself, thereby simplifying the operation process. At the same time, the design of the paddle 507 also enhances the stability and accuracy of the operation. Since the paddle 507 is fixedly connected to the rotating ring 505, the user can more easily control the force and direction of the rotation, avoiding possible sliding or misoperation caused by directly acting on the rotating ring 505, thereby improving the efficiency and accuracy of adjusting the angle of the placement rod 204.

[0033] See also Figure 3 , Figure 4The material of the latch tooth 504 is magnetic metal, and the latch tooth 504 is magnetically attracted to the magnetic ring 508. The two sides of the rotating ring 505 abut against the inner wall of the mounting ring 203 to provide a rotational friction coefficient of the rotating ring 505. The latch tooth 504, as a magnetic metal, can produce a magnetic attraction with the magnetic ring 508, so that the latch tooth 504 can be more stably and accurately aligned with and disengaged from the latching groove 502 during the unlocking and locking process, thereby improving the reliability and efficiency of the operation. At the same time, the abutment between the two sides of the rotating ring 505 and the inner wall of the mounting ring 203 increases the rotational friction coefficient of the rotating ring 505, which ensures that when the user turns the paddle 507, the rotating ring 505 can rotate smoothly and controllably, avoiding excessively fast or excessively slow rotation due to insufficient friction, thereby further improving the stability of the operation and the user experience, and at the same time avoiding the mis-locking of the latch tooth 504.

[0034] See also Figure 3 , Figure 4 The outer side surface of the latch tooth 504 is an inclined structure, and the outer side surface of the latch tooth 504 abuts against the inner wall of the groove 506, so that the latch tooth 504 can unlock and lock more smoothly when subjected to the abutment force of the inner wall of the groove 506. This structure reduces the friction resistance between the latch tooth 504 and the groove 506, making the operation easier. At the same time, the close abutment between the latch tooth 504 and the inner wall of the groove 506 ensures that the placement rod 204 can be firmly locked at the desired angle after adjustment, provides a stable supporting force, and prevents accidental movement or loosening during use, thereby enhancing the stability and safety of the overall structure.

[0035] See also Figure 3 , Figure 4 , multiple snap-in grooves 502 are arranged equidistantly linearly along the central axis of the extension arm 202, and the snap-in grooves 502 are engaged with the latch teeth 504. The equidistant linearly arranged snap-in grooves 502 provide multiple fixed position options for the angle adjustment of the placement rod 204, which means that the user can accurately adjust the placement rod 204 to any preset angle position according to actual needs, thereby meeting the needs of different weft yarn processing or installation. At the same time, the tight engagement of the latch teeth 504 and the snap-in grooves 502 ensures that the placement rod 204 can be firmly locked in the selected position after adjustment, and will not be easily moved or deflected due to external factors, thereby ensuring the accuracy and stability of the weft yarn processing.

[0036] Embodiment 2:

[0037] See also Figure 1 , Figure 2The support arm 201 is rotatably connected to the extension arm 202 through a rotating joint, and the mounting ring 203 and the extension arm 202 are in a coaxial sleeve structure. Due to the connection of the rotating joint, the support arm 201 and the extension arm 202 can rotate flexibly, which increases the freedom and adjustability of the weft yarn frame. The user can easily adjust the angle of the extension arm 202 to adapt to different working environments and needs. At the same time, the coaxial sleeve structure of the mounting ring 203 and the extension arm 202 enables the mounting ring 203 to be stably fixed on the extension arm 202 and can rotate with the rotation of the extension arm 202, ensuring that the mounting ring 203 and the placement rod 204 thereon can always remain in the appropriate position, thereby improving the stability and ease of use of the weft yarn frame.

[0038] See also Figure 1 , Figure 2 A yarn guide rod 3 is installed on the upper outer side of the support rod 1, and a yarn guide plate is installed on the yarn guide rod 3. A base 4 is provided at the bottom end of the support rod 1. The setting of the yarn guide rod 3 and the yarn guide plate provides a clear guide for the weft yarn, which helps to keep the weft yarn neat and orderly, and reduces the confusion and entanglement of the weft yarn during the transportation process, thereby improving production efficiency. At the same time, the setting of the base 4 enhances the stability of the entire weft yarn frame. The base 4 can provide a firm support for the support rod 1, prevent the weft yarn frame from tilting or moving during operation, and ensure the accuracy and safety of weft yarn processing.

[0039] The implementation principle of the utility model is as follows: when the weft yarn needs to be adjusted in angle, first, the paddle 507 is toggled to cause the rotating ring 505 to rotate, so that the inner groove 506 gradually loses its abutment force on the latching tooth 504. At the same time, due to the magnetic attraction between the outer magnetic ring 508 and the latching tooth 504, the inner latching tooth 504 is separated from the latching groove 502, and then the clamping seat 6 and the placing rod 204 are rotated in an angle. When the rotation reaches the desired angle, the paddle 507 is toggled to cause the rotating ring 505 to rotate. When the movable ring 505 rotates in the opposite direction, the inner groove 506 makes an inclined abutment against the latch tooth 504, causing the latch tooth 504 to re-engage with the corresponding latch groove 502, completing the angle adjustment operation of the placement rod 204. Through this process, the unlocking and locking operations of the installation ring 203 can be completed by simply turning the paddle 507, which improves the convenience of angle adjustment of the placement rod 204 and increases its angle adjustment range, which is beneficial to improving the installation applicability of the weft yarn for different usage environments and working conditions.
