Abstract
Description
Technical Field
[0001] This application relates to the field of needle technology for circular knitting machines using the shift loop jacquard technique, specifically to a needle-shifting device for such machines. Background Technology
[0002] In weft knitting, loop transfer is a knitting technique that changes the position of a loop by transferring it from one needle to another. This operation is mainly used to achieve pattern design, structural changes, or functional knitting effects.
[0003] In a circular knitting machine, loops can be transferred between the cylinder and the needles on the dial to create double-sided patterns or three-dimensional structures. During the transfer process, as the original needle of the transferred loop descends, the latch, which is close to the needle bar, will automatically spring back, gradually rotating upwards towards the needle hook to close it. If the yarn is thick, the latch may easily puncture the transferred loop during the upward closing process, causing the loop to split and resulting in an incomplete transfer. Alternatively, some needles may be old and have poor self-rebound, failing to rebound in time. As the needle descends, it may snag the yarn, causing the loop to split and resulting in an incomplete transfer. Utility Model Content
[0004] Therefore, a needle-shifting device is needed for a circular knitting machine to solve the problem of yarn snagging and splitting when the knitting needles spring back in the existing technology.
[0005] To achieve the above objectives, the inventor provides a needle-setting device for a circular knitting machine, comprising:
[0006] The needle-shifting unit includes a mounting frame and a shift lever. The mounting frame is installed on the frame of the circular knitting machine. One end of the shift lever is connected to the mounting frame, and the other end of the shift lever is provided with a needle-shifting part, which has a needle-shifting surface. When the needle tongue needs to rebound, the position where the end of the needle tongue and the gap of the needle bar are located is the intersection position. The needle-shifting part is staggered with the intersection position, and the needle-shifting surface faces the needle tongue, so as to shift the needle tongue during the movement of the knitting needle.
[0007] In some embodiments, the needle-pulling surface is inclined to the needle tongue, and the inclination direction is the direction in which the needle tongue will be pulled up during the movement of the knitting needle.
[0008] In some embodiments, the needle-pulling portion is orthogonal to or inclined to the needle tongue that needs to rebound.
[0009] In some embodiments, the mounting bracket includes:
[0010] A base, which is installed on the frame of a circular jacquard knitting machine;
[0011] A rod frame, which is connected to a base and to one end of a lever.
[0012] In some embodiments, the lever is movable up and down and rotatably connected to the lever holder, and is locked by a first locking element.
[0013] In some embodiments, the lever is provided with a through-rod groove, the lever is movable up and down and rotatably inserted into the through-rod groove, and is locked by a first locking member.
[0014] In some embodiments, the side wall of the through-rod groove is provided with a first threaded hole, and the first locking member is a first bolt. The first bolt is screwed into the first threaded hole and locks the lever when tightened.
[0015] In some embodiments, the base is movably disposed radially along the needle plate at the frame of the circular knitting machine and locked by a second locking element.
[0016] In some embodiments, the base is provided with a strip-shaped adjustment hole, which is arranged radially along the needle plate; the second locking member is a second bolt, and the frame of the circular knitting machine is provided with a second threaded hole; the second bolt passes through the strip-shaped adjustment hole, is screwed into the second threaded hole, and is tightened to lock the base after adjusting the distance between the lever and the knitting needle.
[0017] In some embodiments, the needle-pulling unit is provided in two sets, and the two sets of needle-pulling units are respectively used to pull up the needle tongue of the upper needle plate knitting needle and the needle tongue of the lower needle plate knitting needle.
[0018] Unlike existing technologies, the needle-shifting device of the above-described jacquard circular knitting machine has a mounting bracket that mounts the shifting lever to the frame of the machine, allowing the lever to act on the needle tongue. The shifting part of the lever is staggered with the intersection position, so that when the needle tongue should rebound, the shifting part can enter the gap between the needle tongue and the needle bar. The shifting lever has a shifting surface that can lift the needle tongue. Under the drive of the needle disc, when the knitting needle moves to the position where the needle tongue should rebound, the shifting part is in the state of penetrating the gap between the needle tongue and the needle bar. As the needle disc continues to drive, the shifting part and the knitting needle move in opposite directions, and the movement of the needle tongue is hindered. The needle tongue is lifted by the shifting surface of the shifting part, thereby triggering the mechanism of the needle tongue's autonomous rebound. The needle tongue can then rebound smoothly and in a timely manner, ensuring that the needle tongue of the knitting needle gradually rebounds to the closed needle hook before contacting the loop, so that the needle tongue will not prick the transferred loop and avoid being split. Therefore, the needle-shifting device of the circular knitting machine described in this utility model can assist the knitting needle in rebounding the needle tongue, enabling the needle tongue to rebound in a timely manner or even in advance, thereby solving the problem of insensitive and delayed rebound of old knitting needles and needle tongues. It can also adjust the timing of the needle tongue rebound according to the yarn thickness to adapt to the shifting operation of different yarn thicknesses and ensure clean shifting.
[0019] The above description of the utility model is merely an overview of the technical solution of this application. In order to enable those skilled in the art to better understand the technical solution of this application and to implement it based on the description and drawings, and to make the above-mentioned objectives and other objectives, features and advantages of this application easier to understand, the following description is provided in conjunction with the specific embodiments and drawings of this application.

[0057] In weft knitting, loop transfer is a knitting technique that changes the position of a loop by transferring it from one needle to another. This operation is mainly used to achieve pattern design, structural changes, or functional knitting effects.
[0058] In a circular knitting machine, loops can be transferred between the cylinder and the needles on the dial to achieve double-sided patterns or three-dimensional structures. Typically, during the transfer process, as the original needle of the transferred loop descends, the needle tongue 400, which is close to the needle bar 401, will automatically spring back, gradually rotating from bottom to top towards the needle hook 402 to close it. If the yarn is relatively thick, the needle tongue 400 may easily pierce the transferred loop during its upward closing process, causing the loop to split and resulting in an incomplete transfer. Alternatively, some needles may be old and have insensitive self-rebound mechanisms, failing to rebound in time. As the needle descends, it may snag the yarn, causing the loop to split and resulting in an incomplete transfer.
[0059] Therefore, this utility model provides a needle-pulling device for a circular knitting machine, which is used to pull up the needle tongue 400 when it needs to spring back, so that the needle tongue 400 can be flipped in time or even in advance, ensuring that the needle tongue 400 will not snag the yarn and ensuring a clean transfer.
[0060] Please see Figure 1 and Figure 2 In a specific embodiment, the needle-shifting device of the circular knitting machine includes a needle-shifting unit, which includes a mounting frame and a shifting rod 3. The mounting frame is installed on the frame 8 of the circular knitting machine. One end of the shifting rod 3 is connected to the mounting frame, and the other end of the shifting rod 3 is provided with a needle-shifting part 300. The needle-shifting part 300 is provided with a needle-shifting surface 301. When the needle tongue 400 needs to rebound, the position where the end of the needle tongue 400 and the gap of the needle bar 401 are located is the intersection position 5. The needle-shifting part 300 is staggered with the intersection position 5, and the needle-shifting surface 301 faces the needle tongue 400, so as to lift the needle tongue 400 during the movement of the knitting needle 4.
[0061] The mounting bracket of the needle-shifting unit mounts the shift lever 3 onto the frame 8 of the circular knitting machine, allowing the shift lever 3 to be mounted at a position where it can act on the needle tongue 400 of the knitting needle 4. The needle-shifting part 300 of the shift lever 3 is staggered with the intersection position 5, so that when the needle tongue 400 should rebound, the needle-shifting part 300 can enter the gap between the needle tongue 400 and the needle bar 401. The needle-shifting part has a needle-shifting surface 301 that can lift the needle tongue 400. When the knitting needle 4 moves to the position where the needle tongue 400 should rebound under the drive of the needle plate, the needle-shifting part 300... The needle 400 is in the gap between the needle tongue 400 and the needle bar 401. As the needle plate continues to move, the needle-pulling part 300 and the knitting needle 4 move in opposite directions. The movement of the needle tongue 400 of the knitting needle 4 is hindered and is pulled up by the needle-pulling surface 301 of the needle-pulling part 300, thereby triggering the mechanism of the needle tongue 400's autonomous rebound. The needle tongue 400 can then rebound smoothly and in a timely manner, thus ensuring that the needle tongue 400 of the knitting needle 4 gradually rebounds to the closed needle hook 402 before contacting the loop, so that the needle tongue 400 will not prick the transferred loop and avoid being split. Therefore, the needle-shifting device of the circular knitting machine described in this utility model can assist the knitting needle 4 in rebounding the needle tongue 400, so that the needle tongue 400 can rebound in a timely manner or even in advance, thereby solving the problem of the old knitting needle 4 and the needle tongue 400 being insensitive and lagging in rebound. It can also adjust the timing of the needle tongue 400 rebounding according to the yarn thickness to adapt to the transfer operation of different yarn thicknesses and ensure clean transfer.
[0062] In a specific embodiment, the time when the needle tongue 400 should spring back (when the needle tongue 400 needs to spring back) is the critical moment when the needle tongue 400 of the knitting needle 4 is about to contact but has not yet contacted the yarn; the time when the needle tongue 400 should spring back (when the needle tongue 400 needs to spring back) can be determined according to the specific thickness of the yarn.
[0063] Some processes of the circular knitting machine require the coil of the upper needle to be transferred to the lower needle, or the coil of the lower needle to be transferred to the lower needle. Other processes of the circular knitting machine require the upper needle plate 6 and the lower needle plate 7 to transfer the coil at the same time.
[0064] Therefore, in some embodiments, only one set of the needle-shifting unit may be provided. The needle-shifting unit is located at the upper needle plate or the lower needle plate to be used in processes that require the transfer of the loop of the upper needle plate to the lower needle plate, or the transfer of the loop of the lower needle plate to the lower needle plate, so as to shift the needle tongue 400 of the upper needle plate 6 needle 4 or the needle tongue 400 of the lower needle plate 7 needle 4.
[0065] In some embodiments, the needle-shifting unit is provided in two sets, which are respectively located at the upper needle plate and the lower needle plate to be used in processes that require the upper needle plate 6 and the lower needle plate 7 to transfer the coil at the same time. The two sets of needle-shifting units are respectively used to shift the needle tongue 400 of the needle 4 on the upper needle plate 6 and the needle tongue 400 of the needle 4 on the lower needle plate 7.
[0066] In some embodiments, the pin portion 300 is formed by bending the end of the lever 3 that is not connected to the mounting bracket.
[0067] In some embodiments, the needle-pulling unit is used to pull up the needle tongue 400 of the lower disc needle, and the lever 3 is bent so that the needle-pulling part 300 can extend to the intersection position 5.
[0068] In some embodiments, the needle-pulling unit is used to pull up the needle tongue 400 of the lower needle plate, and the lever 3 is inclined to the axis of the lower needle plate 7 so that the needle-pulling part 300 can extend to the intersection position 5.
[0069] The needle-pulling part 300 can be set at various angles, and various angles can ensure that the needle-pulling part 300 can be inserted into the gap between the needle tongue 400 and the needle bar 401, as shown in the following embodiments:
[0070] Example 1: Please refer to Figure 3 or Figure 4 The needle-pulling part 300 can be orthogonally set to the needle tongue 400 that needs to rebound. When the knitting needle 4 reaches the position where the needle tongue 400 should rebound, the lower needle continues to move down and rotate around the needle plate (the upper needle continues to move radially and rotate around the needle plate). During this process, the needle-pulling part 300 continuously shuttles between the needle tongue 400 and the needle bar 401. The needle tongue 400 will flip over due to the continuous obstruction of its movement.
[0071] Example 2: Please refer to Figure 5 The needle-pulling part 300 is inclined to the needle tongue 400 that needs to rebound, and the inclination direction is gradually inclined towards the needle hook 402 along the rotation direction of the knitting needle 4.
[0072] Example 3: Please refer to Figure 6 The needle-pulling part 300 is inclined to the needle tongue 400 that needs to rebound, and the inclination direction is gradually inclined away from the needle hook 402 along the rotation direction of the knitting needle 4.
[0073] Taking the needle latch 400 of the needle-raising unit used to raise the lower needle plate as an example, the knitting needle 4 will move up and down and rotate around the lower needle plate 7. The knitting needle 4 will gradually move to the position where the needle latch 400 should spring back. When the knitting needle 4 moves to the position where the needle latch 400 should spring back, the needle-raising part 300 passes between the needle latch 400 and the needle bar 401. The knitting needle 4 is in a state of downward movement and continued rotation. During this process, the needle-raising part 300 continuously shuttles between the needle latch 400 and the needle bar 401. When the needle tongue 400 is blocked from moving, the needle-pulling surface 301 gradually pulls up the needle tongue 400 until the needle-pulling part 300 leaves the gap between the needle tongue 400 and the needle bar 401. The needle-pulling part 300 will continue to pull up the subsequent needle 4. The needle-pulling surface 301 pulls up the needle tongue 400 so that the needle tongue 400 is slightly away from the needle bar 401. A gap is formed between the needle tongue 400 and the needle bar 401 for the loop to enter, so that it will not prick the transferred loop, avoid the lower end of the needle tongue 400 from getting caught on the loop, and avoid the yarn from being split.
[0074] The angle of the needle-pulling surface 301 can be varied, and various angles can ensure that the needle-pulling surface 301 will pull up the needle tongue 400, as shown in the following embodiments:
[0075] Example 4: The needle-pulling surface 301 can be arranged parallel to the needle tongue 400 to be pulled up. The needle-pulling unit located on the lower needle plate 7 has its needle-pulling surface 301 parallel to the circumference of the lower needle plate 7, and the needle-pulling unit located on the upper needle plate 6 has its needle-pulling surface 301 parallel to the plate surface of the upper needle plate 6. As long as the needle-pulling part 300 passes through the gap between the knitting needle 4 and the needle bar 401, it can prevent the needle tongue 400 from moving with the knitting needle 4, thus pulling up the needle tongue 400. Therefore, this arrangement also allows the needle tongue 400 to be pulled up during the movement of the knitting needle 4.
[0076] Example 5: The needle-pulling surface 301 can be tilted relative to the needle tongue 400 to be rebounded, and the tilting direction is the direction in which the needle tongue 400 will be pulled up during the movement of the knitting needle 4, such as... Figure 7 or Figure 8 The needle-shifting unit located on the lower needle plate 7 has a needle-shifting surface 301 parallel to the tangent of the lower needle plate 7 and inclined to the needle tongue 400; for example Figure 9 The needle-shifting unit located on the upper needle plate 6 has its needle-shifting surface 301 inclined to the surface of the upper needle plate 6. After the needle-shifting part 300 passes through the gap between the knitting needle 4 and the needle bar 401, the needle-shifting surface 301 can lift the needle tongue 400 as the knitting needle 4 moves.
[0077] Please see Figure 1 In some embodiments, the mounting frame includes a base 1 and a rod 2. The base 1 is mounted on the frame 8 of the jacquard circular knitting machine. The rod 2 is connected to the base 1 and is connected to one end of the lever 3.
[0078] In some embodiments, the lever 3 is movable up and down and rotatably connected to the rod frame 2, and locked by the first locking member. The user can adjust the height and direction of the lever 3 according to the actual height of the intersection position 5, so that the needle-pulling part 300 can be accurately located at the intersection position 5, and the angle between the lever 3 and the knitting can be precisely controlled, so as to more accurately move the needle tongue 400.
[0079] In some embodiments, the lever 3 is provided with a through-rod groove, the lever 3 is movable up and down and rotatably inserted into the through-rod groove, and is locked by a first locking member.
[0080] Please see Figure 1 In some embodiments, the side wall of the through-rod groove is provided with a first threaded hole, and the first locking member is a first bolt 200. The first bolt 200 is screwed into the first threaded hole and locks the lever 3 when tightened, so as to conveniently adjust the installation height of the lever 3.
[0081] In some embodiments, the base 1 is movably disposed on the frame 8 of the circular knitting machine along the needle plate and locked by a second locking member. The user can adjust the distance of the lever 3 from the needle plate according to the actual intersection position 5 so that the needle-pulling part 300 can be accurately positioned at the intersection position 5.
[0082] Please see Figure 2 In some embodiments, the base 1 is provided with a strip-shaped adjustment hole 100, which is arranged radially along the needle plate; the second locking member is a second bolt 101, and the frame 8 of the circular knitting machine is provided with a second threaded hole; the second bolt 101 passes through the strip-shaped adjustment hole 100, is screwed into the second threaded hole, and after adjusting the distance between the lever 3 and the knitting needle 4, it is tightened to lock the base 1, so as to conveniently adjust the installation position of the lever 3.
[0083] In some embodiments, the strip-shaped adjustment hole 100 may be a waist-shaped hole.
[0084] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application.
