Embodiment 1

[0041] weft selector, such as figure 1 with figure 2 As shown, the permanent magnet sheet 1 is included. The permanent magnet sheet 1 is a thin sheet with a thickness of 3-5mm. Its specific thickness can be determined according to load-bearing requirements. The permanent magnet piece 1 is embedded with a first permanent magnet block 11 and a second permanent magnet block 12 . The first permanent magnet block 11 has a first pole 111 and a second pole 112 . The polarity of the first pole 111 and the second pole 112 are opposite. figure 1 Taking the counterclockwise direction as standard, the first pole 111 is located in front of the second pole 112 .

[0042] The permanent magnet piece 1 is also embedded with a second permanent magnet block 12 . The second permanent magnet block 12 has a third pole 121 and a fourth pole 122 . The third pole 121 is opposite in polarity to the fourth pole 122 . Based on the counterclockwise direction, the first permanent magnet block 11 i...

Embodiment 2

[0056] Such as Figure 7 As shown, the difference between Embodiment 2 and Embodiment 1 lies in that only the first permanent magnet block 11 is provided on the permanent magnet sheet 1 , and the second permanent magnet block 12 is not provided. All the other structures and methods of use are the same as in Example 1.

[0057] Such as Figure 7 As shown, in the first use state, the electromagnetic sheet 2 is in contact with the second block 14 . When there is a current in the first direction in the coil 23, the first pole 111 attracts the coil 23, and the second pole 112 repels the coil 23, so that the electromagnetic sheet 2 rotates counterclockwise until the electromagnetic sheet 2 is blocked by the first block 13 and cannot continue turn. Such as Figure 8 Shown is the second use state of this embodiment. At this time, if the current in the second direction opposite to the first direction passes through the coil 23, the first pole 111 repels the coil 23, and the second ...

Embodiment 3

[0059] Such as Figure 9 As shown, the difference between Embodiment 3 and Embodiment 1 is that only the second permanent magnet block 12 is provided on the permanent magnet sheet 1 , and the first permanent magnet block 11 is not provided. All the other structures and methods of use are the same as in Example 1.

[0060] Such as Figure 10 As shown, in the first use state, the electromagnetic sheet 2 is in contact with the second block 14 . When there is current in the coil 23 in the first direction, the third pole 121 repels the coil 23, and the fourth pole 122 attracts the coil 23. In this embodiment, it can be set so that the repulsion force of the third pole 121 to the coil 23 is greater than that of the fourth pole 122 to the coil 23 Appeal. Due to the blocking of the second block 14, the electromagnetic sheet 2 cannot rotate clockwise. Therefore, the electromagnetic sheet 2 can only rotate counterclockwise. The electromagnetic sheet 2 rotates counterclockwise until...

Abstract

The invention discloses a weft selector comprising a weft selecting pointer, a permanent-magnet sheet and an electromagnetic sheet, wherein the permanent-magnet sheet and the electromagnetic sheet can be arranged in a relatively-movable mode, a first permanent-magnet block is arranged on the permanent-magnet sheet, a coil is arranged on the electromagnetic sheet, and the coil is provided with a leading-out wire. By using the matching mode of the first permanent-magnet block and the electromagnetic sheet, when the coil is electrified with current of a first direction, the magnetism of the first permanent-magnet block is interactive with the magnetism of the coil to drive the relative movement of the permanent-magnet sheet and the electromagnetic sheet; when the coil is electrified with current of a second direction, the magnetism of the first permanent-magnet block is interactive with the magnetism of the coil in order to drive the permanent-magnet sheet and the electromagnetic sheet to restore a position before the movement, and the first direction is opposite to the second direction; and the weft selecting pointer is arranged on the permanent-magnet sheet or the electromagnetic sheet. In the invention, the weft selector has the advantages of simple structure, small volume, high reciprocating speed and high frequency, can realize high-speed operation and saves electricity and energy when used.

Description

technical field [0001] The invention relates to a weft selector and a weft selector. Background technique [0002] Fabrics are usually woven from warp and weft threads. When weaving fabrics with complex patterns or multiple color combinations, it is necessary to preset the weft threads of various colors to be used. After the warp threads form the shed, introduce the weft threads of the corresponding color or pattern into the shed, and weave gradually to form a certain pattern or color. Combined fabric. When weaving a fabric, first select the weft threads to be used. In the prior art, a weft selection device is used for selection, and the weft selection device is used to guide the selected weft to a designated position. The operating frequency of the weft selection device has a decisive influence on the speed of fabric production. In the process of mass production, the weft selection device needs to move quickly and with high frequency. However, the weft selection device...
