Description

Technical Field

[0001] This invention belongs to the field of mechanical technology and relates to a needle plate with a twisted needle, particularly a needle plate with a twisted needle that has good structural performance. Background Technology

[0002] Computerized flat knitting machines use a starting device to start the fabric, allowing the fabric to be pulled evenly from the start, thus effectively pulling the subsequent fabric and reducing yarn consumption. With the rapid development of computerized flat knitting machines, the starting and pulling technology has become increasingly sophisticated.

[0003] The base-raising device generally uses a needle plate mounted on the base plate of the threading plate, with steel wires passing through the needle plate to pull the fabric. Existing needle plates are usually integrated with the threading plate, and the threading needles on the needle plate are basically welded to the needle plate (threading plate) individually. After long-term use, the threading needles are prone to breakage. In this case, replacing the threading needles requires replacing the entire threading plate, which is inconvenient for installation and disassembly. In addition, the positional relationship between the needle plate and other components needs to be repositioned, making the operation inconvenient.

[0004] In summary, to address the shortcomings of existing needle plate structures, this invention designs a needle plate with a twisted needle that has a reasonable structure and good performance. Summary of the Invention

[0005] To address the problems existing in the prior art, this invention provides a needle plate with a twisted needle that has a reasonable structure and good performance.

[0006] The objective of this invention can be achieved through the following technical solution: a needle plate with a twisted needle, mounted on a threading plate, the needle plate comprising:

[0007] The main body has several snap-fit ​​slots on both the left and right sides;

[0008] The threading needles are arranged in a row on the top of the main body, and each threading needle is integrally set with the main body. Each threading needle includes a needle part and a twisting part. The twisting part is connected to the main body. A threading hole is opened through the needle part, and each threading hole is coaxially arranged.

[0009] As a further improvement to this design, the threading needles are spaced at equal intervals, and a groove is provided between two adjacent threading needles.

[0010] As a further improvement in this case, the plane where the needle is threaded is perpendicular to the plane where the main body is located.

[0011] As a further improvement to this design, the upper end of the needle-threading section is wedge-shaped, and the thread-threading hole is located close to the upper end of the needle-threading section.

[0012] As a further improvement in this case, the bottom part of the main body extends downward to form a pulling part, and a notch is opened on one side of the pulling part.

[0013] A method for manufacturing a needle plate with a twisted needle, the specific steps of which are as follows:

[0014] S1: The body is formed by stamping or laser cutting of steel sheet;

[0015] S2: Round off the needle-threading part of the threading needle;

[0016] S3: Twist the threading needle by clamping the needle-threading part;

[0017] S4: Calibrate the threading hole.

[0018] As a further improvement to this case, in step one, the threading hole and the body are formed in one piece.

[0019] Compared with the prior art, the present invention has a reasonable structural design. By twisting the threading needles integrated with the needle plate, the threading needles are arranged in a longitudinal row, making the threading holes on the needles coaxial. This facilitates the steel wire on the threading plate to pass through the threading holes for the initial lifting work. At the same time, the twisted structure can enhance the structural strength of the threading needles, further ensuring the overall structural stability of the needle plate, which is beneficial for long-term use and reduces the number of needle plate replacements.

[0029] The technical solution of the present invention will be further described below with reference to the embodiments and accompanying drawings.

[0030] like Figures 1 to 3 As shown in Embodiment 1 of the present invention:

[0031] This needle plate with twisted needles is mounted on the threading plate. The needle plate includes:

[0032] The main body 10 has multiple snap-fit ​​slots 11 on its left and right sides respectively;

[0033] The threading needles 20 are arranged in a row on the top of the main body 10, and each threading needle 20 is integrally set with the main body 10. Each threading needle 20 includes a needle part 21 and a twisting part 22. The twisting part 22 is connected to the main body 10. A threading hole 211 is provided through the needle part 21, and each threading hole 211 is coaxially arranged.

[0034] Existing needle plates are usually integrated with threading plates. The threading needles 20 on the needle plate are basically welded onto the needle plate (threading plate) as individual needles. After long-term use, the threading needles 20 are prone to damage. In this case, replacing the threading needles 20 requires replacing the entire threading plate, which is inconvenient for installation and disassembly. In addition, the positional relationship between the needle plate and other components needs to be repositioned, which is inconvenient for operation.

[0035] To address this, the present invention provides a needle plate with twisted needles. By twisting the threading needles 20 integrally set with the needle plate, the threading needles 20 are arranged in a longitudinal row, making the threading holes 211 on the threading needles 20 coaxial. This facilitates the steel wire on the threading plate to pass through the threading holes 211 for the initial lifting work. At the same time, the twisted structure can enhance the structural strength of the threading needles 20, further ensuring the overall structural stability of the needle plate, which is beneficial for long-term use and reduces the number of times the needle plate needs to be replaced.

[0036] Specifically, when the needle plate is actually installed on the threading plate, two adjacent needle plates are interlocked and snapped together. At the same time, the needle plate and the threading plate can also be snapped together. Multiple snapping grooves 11 on the left and right sides of the needle plate facilitate the interlocking and snapping between the needle plate and the needle plate or the threading plate to achieve a tenon and mortise joint. Finally, the clamping block 30 is used to securely snap together. The shape of the clamping block 30 can also be selected as needed and is not limited here.

[0037] The threading needle 20 is integrally set with the body 10. The upper part of the threading needle 20 is the threading part 21, and the threading hole 211 is opened on the threading part 21 to facilitate the passage of steel wire. The lower part is connected to the body 10 and forms a twisting part 22 after twisting. The threading part 21 always remains flat, which makes it easy for each threading hole 211 to remain in a round hole state, which is conducive to the passage of steel wire.

[0038] Preferably, each threading needle 20 is arranged at equal intervals, and a groove 23 is provided between two adjacent threading needles 20.

[0039] In this invention, grooves 23 are preferably provided between the threading needles 20 to provide sufficient space for operation when the threading needles 20 are twisting. In addition, the equal spacing of each threading needle 20 can also reduce the risk of the wire accidentally touching the threading needle 20 to a certain extent.

[0040] Furthermore, the plane where the needle-threading part 21 is located is perpendicular to the plane where the body 10 is located.

[0041] In the initial state, such as Figure 3 As shown, the threading needle 20 and the body 10 are on the same plane. After the twisting operation, the twisting part 22 on the threading needle 20 is twisted, and the threading part 21 remains in a planar state, but the plane where the threading part 21 is located is perpendicular to the plane where the body 10 is located, so that each threading hole 211 is on the same axis, which makes it easier for the steel wire to pass through.

[0042] Preferably, the upper end of the needle-threading portion 21 is wedge-shaped, and the thread-threading hole 211 is located close to the upper end of the needle-threading portion 21. Here, it is preferable that the thread-threading hole 211 is located close to the upper end of the needle-threading portion 21, that is, relatively far away from the twisting portion 22, so as to avoid affecting the structure of the thread-threading hole 211 during twisting operation.

[0043] The upper end of the needle threading section 21 is wedge-shaped, which helps to reduce the resistance of the needle plate when threading the yarn and helps to maintain the stability of the steel wire.

[0044] It is worth mentioning that there is actually a small distance between the torsion part 22 and the body 10. That is, the length of the torsion part 22 in the initial state is sufficient for the torsion work. After the torsion is completed, the part at the bottom of the torsion part 22 where it connects with the body 10 still remains on the same plane as the body 10. This avoids the torsion part 22 from starting to twist from the connection point with the body 10 (the groove 23 position), thus avoiding the risk of the torsion part 22 breaking after the torsion work.

[0045] Furthermore, the actual degree of twist (twist angle) of the twisting part 22 can be determined as needed, as long as the threading holes 211 on the needle part 21 are coaxial. However, in order to ensure the structural stability of the twisting part 22 (the entire threading needle 20) and avoid unnecessary excessive twisting, it is preferable that the twisting part 22 rotates through a small angle so that the threading holes 211 are coaxial. In this embodiment, it is preferable that the twisting part 22 rotates through 90 degrees.

[0046] Furthermore, the bottom part of the main body 10 extends downward to form a pulling part 12, and a notch 121 is provided on one side of the pulling part 12.

[0047] After the needle plate is installed on the threading plate, it will be subjected to vertical pulling force during operation. The setting of the pulling part 12 here facilitates the extension of the needle plate length in the vertical direction (i.e., the span in the vertical direction), and avoids the needle plate being too short and swinging back and forth under the action of pulling force. At the same time, a notch 121 is opened on one side of the pulling part 12, and the bottom of the needle plate is also locked to the threading plate by the clamping block 30 to ensure that the connection between the needle plate and the threading plate is stable.

[0048] If the overall length of the needle plate in the vertical direction is directly increased, the total area of ​​the needle plate will increase, which will require a larger mounting groove to be opened on the threading plate. This will reduce the structure of the threading plate and affect the overall stability of the threading plate. Therefore, the setting of the pulling part 12 can increase the vertical span of the needle plate without affecting the structural stability of the threading plate.

[0049] like Figure 8 As shown in Embodiment Six, the preferred shape of the pulling part 12 can also be set as a teardrop or a partially circular structure. The threading plate can be equipped with a matching structure to form a nested form, which improves the stability of the assembly and resists some external forces.

[0050] like Figures 4 to 7 As shown in Embodiments 2 to 5, the snap-fit ​​grooves 11 on both sides of the needle plate can also adopt various other structures, which are not limited by the present invention.

[0051] The present invention also provides a method for manufacturing a needle plate with a twisted needle, the specific steps of which are as follows:

[0052] Step 1: Form the body 10 by stamping or laser cutting steel sheet;

[0053] Preferably, in the first step, the thread hole 211 and the body 10 are formed in one piece.

[0054] Specifically, during production, the initial structure of the body 10 is formed by stamping thin steel sheets on a stamping machine, and the snap-fit ​​groove 11 and the wire hole 211 on the body 10 are completed in one stamping; or the body 10 is formed by laser cutting thin steel sheets, and the snap-fit ​​groove 11 and the wire hole 211 are also formed in one stamping.

[0055] Step 2: Round off the needle part 21 on the threading needle 20;

[0056] Next, the top of the threading needle 20 is polished and rounded.

[0057] Step 3: Twist the threading needle 20 by clamping the needle part 21;

[0058] During the twisting operation, the needle plate body 10 is flattened, and the needle part 21 of each threading needle 20 is clamped by a robot or manually and rotated at a certain angle so that the needle part 21 is perpendicular to the body 10. At this time, the twisting part 22 of the threading needle 20 is formed.

[0059] Step 4: Calibrate thread hole 211.

[0060] Finally, the threading holes 211 on each threading needle 20 are calibrated. For any threading needle 20 that does not conform, the third step is repeated until all threading holes 211 are coaxial.

[0061] The needle plate with twisted needles has a reasonable structure. The threading needles 20, which are integrally set with the needle plate, are twisted to make the threading needles 20 arranged in a longitudinal row. This makes it possible for the threading holes 211 on the threading needles 20 to be coaxial, which facilitates the steel wire on the threading plate to pass through the threading holes 211 for the bottoming work. At the same time, the twisted structure can enhance the structural strength of the threading needles 20, further ensuring the overall structural stability of the needle plate, which is conducive to long-term use and reduces the number of needle plate replacements.

Any modifications, additions, or substitutions made by those skilled in the art to the specific embodiments described herein, or similar substitutions, should be covered within the scope of protection of the present invention.
