Description

Technical Field

[0001] The invention relates to the technical field of knitting machinery, in particular to a magnetic isolation structural component for an electromagnet needle selector. Background Art

[0002] Common needle selectors include 8-knife head, 10-knife head, 12-knife head and 16-knife head needle selectors, etc. They have different selection performances according to the number of knife heads. In order to ensure that the needle selector can operate accurately, the positioning accuracy of the coil core is very important. If the distance between the coil core and the knife head position is not appropriate, too far or too close, it may cause the needle selector to have insufficient or excessive action force, resulting in fabric defects. At the same time, the fixing method of the coil core is also very important. It needs to be fixed and stable and will not shift due to vibration. Magnetic isolation is to suppress the spread of the magnetic field by placing a magnetic isolation shield around the electromagnet, such as an iron plate or other non-magnetic material. The magnetic isolation shield can effectively prevent the magnetic field of the electromagnet from affecting the surrounding objects, especially those objects that do not want to be selected. Through the magnetic isolation shield, we can control the selection range of the needle selector to ensure that only the target needle or magnetic material is affected by the electromagnet, and other non-magnetic materials will not be misselected or interfered. This helps to improve the accuracy and efficiency of the needle selector.

[0003] At present, a Chinese patent with authorization announcement number CN209508547U discloses a magnetic isolation structure for an electromagnet needle selector, which is used to isolate the magnetic field between coil cores. The magnetic isolation structure includes a first partition and several second partitions. A plurality of first grooves are formed between the first partition and two adjacent second partitions. The several second partitions are connected to the first partition. The coil core is placed in the first groove. The magnetic rod of the coil core is fixed to the needle selector through a fixed pressing plate. The two ends of the fixed pressing plate have second grooves. The second grooves are fitted with the magnetic rod of the coil core. The fixed pressing plate and the needle selector are both provided with holes. The holes of the fixed pressing plate are fitted with the holes of the needle selector for fixation. The magnetic isolation structure facilitates the installation of the coil core, has high installation positioning accuracy, and has good heat dissipation performance.

[0004] However, the magnetic isolation structure used for the electromagnetic needle selector is block-shaped as a whole, uses more resources and has a high production cost. Summary of the invention

[0005] In view of this, an object of the present invention is to provide a magnetic isolation structure for an electromagnet needle selector to achieve the purpose of reducing costs.

[0006] In order to solve the above technical problems, the technical solution of the present invention is: a magnetic isolation structure for an electromagnet needle selector, comprising an iron partition, wherein the iron partition is folded along its own length direction to form a plurality of first grooves, and the end of the iron partition has a folded section, and the folded section is bent at one end away from the iron partition to form a plurality of second grooves, the first grooves and the second grooves are staggered, and the first grooves and the second grooves are both used to place the coil core.

[0007] To implement the above technical solution, the iron partition is bent to obtain multiple first grooves, and the folded section is bent to obtain multiple second grooves. The coil core is placed in the first grooves and / or the second grooves. Since the iron partition and the folded section are in sheet form, materials can be greatly saved and production costs can be reduced.

[0008] As a preferred solution of the present invention, a first positioning hole is formed at the end of the iron partition, and a second positioning hole is formed at one end of the folded section close to the first positioning hole.

[0009] To implement the above technical solution, screws are passed through the first positioning hole and the second positioning hole to fix the iron partition and the folded section to the needle selector housing.

[0010] As a preferred solution of the present invention, a first connecting groove and a second connecting groove are provided on the folded section, and the first connecting groove corresponds to the second connecting groove after the folded section is folded.

[0011] To implement the above technical solution, the first connecting groove and the second connecting groove are opened on the folded section. After the folded section is folded, the first connecting groove and the second connecting groove can correspond to each other, so that the connection between the folded section and the needle selector housing is tighter.

[0012] As a preferred solution of the present invention, the cross-sections of the first connecting groove and the second connecting groove are both arched.

[0013] The above technical solution is implemented so that the screws can be placed in the first connecting groove and the second connecting groove to fix the folded section on the needle selector housing.

[0014] In summary, the present invention has the following beneficial effects: The magnetic isolation structure adopts an integrated iron partition design, which improves the integrity and durability of the product, simplifies the production process, reduces the manufacturing difficulty, and realizes convenient installation and precise positioning of the coil core. At the same time, it has the advantages of low cost, light weight, and less space, and has good heat dissipation performance. BRIEF DESCRIPTION OF THE DRAWINGS
