Description

A quick-release structure for a dual-row needle selector Technical Field

[0001] This utility model relates to the field of dual-row needle selector technology, and in particular to a quick-release structure for a dual-row needle selector. Background Technology

[0002] Electromagnetically driven double-row needle selectors are an important needle selection device commonly used in circular knitting machines. Their structure generally includes an electromagnet that generates a magnetic field to drive the needle selection action, a needle selector plate that moves under the influence of the magnetic field and selects the needle, a circuit board that controls the current direction of the electromagnetic coil, and a mounting base that fixes the various components of the needle selector. During operation, the needle selector receives a voltage signal from the circuit board. The iron core in the electromagnet is magnetized and interacts with the permanent magnet in the needle selector plate, pushing the needle selector blade in the plate to rotate. By changing the current direction in the coil of the electromagnet, the needle selector blade can swing between two extreme positions, thereby controlling the movement of the knitting needle and realizing the needle selection function. It has advantages such as compact structure, convenient installation, rapid heat dissipation, and low interference.

[0003] In existing dual-row needle selectors, the mounting structure for mounting the electromagnet is generally integrally formed with the mounting base for fixing the other components of the needle selector, which is not conducive to the assembly, maintenance and replacement of the electromagnet. Summary of the Invention

[0004] The purpose of this invention is to propose a quick-assembly structure for a double-row needle selector, which facilitates the rapid assembly, repair, and replacement of electromagnets, thereby overcoming the shortcomings of the existing technology.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A quick-release structure for a dual-row needle selector includes a fixed frame, a needle selector plate, a first electromagnet group, and a second electromagnet group.

[0007] The needle selection plates are provided in an even number, and the needle selection plates are evenly installed in two rows on the top of the fixed frame, and the needle selection plates swing relative to the fixed frame.

[0008] The first electromagnet group and the second electromagnet group have the same structure. Both the first electromagnet group and the second electromagnet group include a mounting base, an electromagnet and a circuit board. The electromagnet is mounted on the mounting base and is electrically connected to the circuit board.

[0009] The first electromagnet group and the second electromagnet group are installed side by side below the selection needle plate, and the mounting base of the first electromagnet group is integrally formed with the fixed frame, while the mounting base of the second electromagnet group is detachably installed on the fixed frame.

[0010] The number of electromagnets in the first electromagnet group and the second electromagnet group is the same as the number of the needle selection plates, and each electromagnet corresponds to a permanent magnet in one of the needle selection plates.

[0011] Preferably, it also includes a magnetic shielding sheet, which is detachably installed between the electromagnets of the first electromagnet group and the electromagnets of the second electromagnet group.

[0012] Preferably, the magnetic shielding sheet is U-shaped;

[0013] One end of the magnetic shielding sheet is fitted between the mounting base in the first electromagnet assembly and the electromagnet located at one end of the mounting base;

[0014] The other end of the magnetic shielding sheet is fitted between the mounting base in the first electromagnet assembly and the electromagnet located at the other end of the mounting base.

[0015] Preferably, the side wall of the mounting base is recessed inward and provided with a positioning groove, and the electromagnet is accommodated inside the positioning groove.

[0016] Preferably, multiple positioning slots are provided, and the positioning slots are evenly distributed on two opposite sidewalls of the mounting base, with all the positioning slots arranged alternately.

During electromagnet assembly, the electromagnets of both the first and second groups can be installed simultaneously, along with the electrical connections between each electromagnet and the circuit board. After the module structures of the first and second electromagnet groups are assembled, the second electromagnet group is then mounted on the fixed frame, enabling rapid installation of the double-row needle selector.

[0026] The components include: a fixed frame 1, a pin selection plate 2, a permanent magnet 21, a first electromagnet group 3, a mounting base 31, a positioning groove 311, an electromagnet 32, a circuit board 33, a second electromagnet group 4, and a magnetic shielding sheet 5. Detailed Implementation

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0028] This technical solution provides a quick-assembly structure for a dual-row needle selector, including a fixed frame 1, a needle selector plate 2, a first electromagnet group 3, and a second electromagnet group 4.

[0029] The needle selection plates 2 are provided in an even number, and the needle selection plates 2 are evenly installed in two rows on the top of the fixed frame 1, and the needle selection plates 2 swing relative to the fixed frame 1.

[0030] The first electromagnet group 3 and the second electromagnet group 4 have the same structure. Both the first electromagnet group 3 and the second electromagnet group 4 include a mounting base 31, an electromagnet 32 ​​and a circuit board 33. The electromagnet 32 ​​is mounted on the mounting base 31 and is electrically connected to the circuit board 33.

[0031] The first electromagnet group 3 and the second electromagnet group 4 are installed side by side below the needle plate 2, and the mounting base 31 of the first electromagnet group 3 is integrally formed with the fixed frame 1, and the mounting base 31 of the second electromagnet group 4 is detachably installed on the fixed frame 1.

[0032] The number of electromagnets 32 in the first electromagnet group 3 and the second electromagnet group 4 is the same as the number of the needle selection plate 2, and each electromagnet 32 ​​corresponds to a permanent magnet 21 in one of the needle selection plates 2.

[0033] In existing dual-row needle selectors, the mounting structure for installing the electromagnet is generally integrally formed with the mounting base for fixing the other components of the needle selector, which is not conducive to the assembly, maintenance, and replacement of the electromagnet. Therefore, in order to achieve rapid assembly, maintenance, and replacement of the electromagnet, this technical solution proposes a quick-assembly structure for a dual-row needle selector, as shown in Figures 1-4, including a fixing frame 1, a needle selector plate 2, a first electromagnet group 3, and a second electromagnet group 4.

[0034] Specifically, in this design, the mounting base 31 of the first electromagnet group 3 is integrally formed with the fixed frame 1, and the mounting base 31 of the second electromagnet group 4 is detachably installed on the fixed frame 1. During the assembly of the electromagnets 32, the electromagnets 32 of the first electromagnet group 3 and the second electromagnet group 4 can be installed simultaneously, and the electrical connections between each electromagnet 32 ​​and the circuit board 33 can be established. After the module structures of the first electromagnet group 3 and the second electromagnet group 4 are assembled, the second electromagnet group 4 is then installed on the fixed frame 1, thus achieving rapid installation of the double-row needle selector. Furthermore, when the electromagnets 32 of the needle selector need repair or replacement, specific electromagnets can be quickly repaired or replaced, which helps improve the repair speed of the large circular knitting machine and thus improves its production efficiency.

[0035] Furthermore, it also includes a magnetic shielding sheet 5, which is detachably installed between the electromagnet 32 ​​of the first electromagnet group 3 and the electromagnet 32 ​​of the second electromagnet group 4.

[0036] In a preferred embodiment of this technical solution, in order to prevent mutual interference between the electromagnets 32 of the first electromagnet group 3 and the second electromagnet group 4, a magnetic shielding sheet 5 is added between the first electromagnet group 3 and the second electromagnet group 4 to avoid electromagnetic interference.

[0037] It should be noted that the magnetic shielding sheet 5 in this solution can be made of non-magnetic or weakly magnetic materials such as aluminum or stainless steel, and there are no restrictions here.

[0038] To further explain, the magnetic shielding sheet 5 is U-shaped;

[0039] One end of the magnetic shielding sheet 5 is fitted between the mounting base 31 in the first electromagnet group 3 and the electromagnet 32 ​​located at one end of the mounting base 31.

[0040] The other end of the magnetic shielding sheet 5 is fitted between the mounting base 31 in the first electromagnet assembly 3 and the electromagnet 32 ​​located at the other end of the mounting base 31.

[0041] As a specific embodiment of the above, the magnetic shielding sheet 5 of this solution is U-shaped, which facilitates the quick installation and disassembly of the magnetic shielding sheet 5.

[0042] Furthermore, the mounting base 31 has an inwardly recessed positioning groove 311 on its side wall, and the electromagnet 32 ​​is accommodated inside the positioning groove 311. This allows for more accurate assembly and positioning of the electromagnet 32, making assembly during production easier and more convenient, and also facilitating rapid installation and disassembly during product maintenance and replacement.

[0043] To further explain, multiple positioning grooves 311 are provided, and the positioning grooves 311 are evenly distributed on the two opposite side walls of the mounting base 31, with all the positioning grooves 311 being staggered.

[0044] The electromagnet 32 ​​is housed inside the positioning groove 311. This allows for a more compact needle selector.

[0045] Furthermore, the circuit board 33 is provided with one piece, and all the electromagnets 32 are electrically connected to the circuit board 33. This simplifies the composition of the first electromagnet group 3 and the second electromagnet group 4.

[0046] To further explain, the mounting base 31 of the second electromagnet assembly 4 is connected to the fixed frame 1 by screw threads. This facilitates the quick and stable installation of the second electromagnet assembly 4.
