[0002] The core function of the needle selector, as an indispensable electromagnetic component in textile machinery, is to accurately select and drive the needles on the textile machine through precise electromagnetic control technology to achieve complex textile patterns and designs. Electromagnetic needle selectors are widely used in automation equipment and textile processing industries. It not only improves production efficiency, but also ensures the consistency and accuracy of textiles. The working principle of the electromagnetic needle selector is based on the principle of electromagnetic induction, that is, the corresponding magnetic field changes are generated by changing the intensity and direction of the current. This changing magnetic field acts on the armature, causing it to produce corresponding actions, thereby achieving accurate selection and control of the needle.

[0003] There are still some shortcomings in the needle selectors currently on the market. For example, a Chinese patent with the announcement number CN207159501U discloses a strong magnetic needle selector, which includes a box body, a chip, a plurality of electromagnets and a corresponding plurality of cutter heads, each of which includes a frame, a coil and an iron core, the coil is wound around the outside of the frame, the iron core is inserted into the inside of the frame, the front end of the iron core faces the magnet on the cutter head, and a magnetic enhancement block with magnetism is placed at the tail end of the iron core.

[0004] The placement mechanism of the core coil of the existing strong magnetic needle selector has some limitations, which increases the production cost. The complex structure also means that more expertise and time are required for maintenance and repair, which may also affect production efficiency. Summary of the invention

The semicircular area surrounded by the two magnetic isolation sheets will form a relatively independent magnetic isolation environment. S2, fasten the iron core coil into the needle selector housing through the fixing block; S3. Install the front and rear covers so that each coil is in a closed magnetic isolation space to enhance the magnetic field strength.

[0007] To implement the above technical solution, a relatively independent magnetic isolation environment is created by utilizing magnetic isolation sheets and support blocks, which effectively isolates external magnetic field interference, strengthens the magnetic field strength and stability generated by the iron core coil, thereby improving the performance and accuracy of the needle selector, and reducing equipment failure rates and maintenance costs due to unstable magnetic fields. At the same time, it simplifies the assembly process, improves production efficiency, and brings significant economic benefits to the enterprise.

It not only provides stable and reliable support for the core coil and effectively disperses the pressure, but also significantly enhances the performance of the electromagnetic equipment and reduces magnetic leakage. It embodies the exquisite design of structural details and in-depth consideration of technical optimization, and lays a solid foundation for performance improvement and reliability assurance of electromagnetic equipment.

[0025] The specific implementation modes of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.

[0026] A novel needle selector core coil placement method comprises the following steps: S1, placing the magnetic isolation sheets 5 on the support block in sequence, and the semicircular area surrounded by the two magnetic isolation sheets 5 will form a relatively independent magnetic isolation environment; S2, fasten the iron core coil 3 to the needle selector housing 2 through a fixing block; S3. Install the front and rear covers so that each coil 32 is in a closed magnetic isolation space to enhance the magnetic field strength.

[0027] A novel needle selector iron core coil placement mechanism, which is square in shape. It includes a T-block 1, a needle selector housing 2 and an iron core coil 3. A support rod 4 is horizontally arranged on the inner wall of the needle selector housing 2. The bottom wall of the T-block 1 is fixedly connected to the top wall of the support rod 4. There are multiple T-blocks 1 and they are arranged in a horizontal position. The T-blocks 1 are arranged in two groups, front and back, and are placed in a staggered manner to avoid direct contact between magnetic isolation sheets 5. The outer wall of the T-block 1 is provided with a magnetic isolation sheet 5. The magnetic isolation sheet 5 includes a connecting portion 51, two vertical portions 52 and two arc portions 53. The two sides of the connecting portion 51 are respectively connected to the two vertical portions 52, and the arc portion 53 is connected to one end of the vertical portion 52 away from the connecting portion 51.

[0028] The outer wall of the support rod 4 is provided with a slot body 6 for placing the core coil 3, thereby limiting the core position of the coil 32. The fixing block 8 fixes the core coil 3 in the slot body 6 and fixes it by screws. The top walls at both ends of the support rod 4 are fixedly connected with edge support blocks 7, and the edge support blocks 7 cooperate with the magnetic isolation sheet 5 to support the core coil 3 at the edge. The core coil 3 includes a rod body 31 and a coil 32. The coil 32 is fixedly arranged on the outer wall of one end of the rod body 31, and the rod body 31 is fixed in the slot body 6.

[0029] The edge support block 7 is arranged in an arc shape toward the core coil 3 , and the arc shape cooperates with the magnetic isolation sheet 5 to stably support the core coil 3 .

[0030] The outer wall of the T-block 1 matches the outer wall of the magnetic isolation sheet 5, and can better fit the magnetic isolation sheet 5 to reduce magnetic field leakage. The structural sealing is enhanced to prevent erosion by external factors, while optimizing the assembly process and improving efficiency and accuracy. It provides precise positioning and stable support for the core coil 3, effectively preventing shaking and ensuring the precise operation of the needle selector. At the same time, it optimizes the heat dissipation effect, simplifies the assembly process, and enhances the overall structural strength, comprehensively improving the performance, durability and reliability of the needle selector.

[0031] By utilizing the fixed connection between the T-block 1 and the needle selector housing 2 and the cooperation of the magnetic isolation sheet 5, a stable and accurate coil 32 positioning mechanism is formed. The T-block 1 is arranged in a horizontal position, and the circular groove formed between the magnetic isolation sheets 5 ensures the precise placement of the coil 32. The synergistic effect of the edge support block 7 and the magnetic isolation sheet 5 enhances the stability of the outermost coil 32. At the same time, it has the flexibility of modular design and the number of coils 32 can be easily adjusted as needed. The use of the magnetic isolation sheet 5 optimizes the magnetic isolation effect and reduces electromagnetic interference, thereby improving the accuracy and performance of the needle selector.

[0032] When in use, the T-block 1 must first be evenly and horizontally fixedly connected to the top wall of the support rod 4. Note that it should be set into two groups, front and back, and placed alternately to avoid direct contact with the magnetic isolation sheets 5. Subsequently, a magnetic isolation sheet 5 is sleeved on the outer wall of each T-block 1, and a circular groove will be formed between the magnetic isolation sheets 5 to limit the position of the core coil 3. Finally, the core coils 3 are placed one by one in the two magnetic isolation sheets 5, and the rod body 31 is fixed in the groove body 6. At the same time, the edge support block 7 is used in conjunction with the magnetic isolation sheet 5 to support the four core coils 3 at the edge to complete the installation. The mechanism is cleverly designed, easy to install and disassemble, and can ensure the precise operation of the needle selector.

[0033] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
