Problems solved by technology

Shuttle looms are often projected back and forth repeatedly due to the large size and weight of the shuttle, which brings about a series of problems such as large vibration, high noise, slow speed, and low efficiency of the loom
However, the weft insertion methods of shuttleless looms have their own disadvantages and have their own weaving types that cannot be applied.
Especially in terms of the width of the door, most of the weft insertion pieces of shuttleless looms at present have a trend of decreasing from strong to weak during the weft insertion process. Therefore, there is a certain limit weaving width, which cannot meet the requirements of larger weaving. Width Requirements

Embodiment 1

[0031] A variable reluctance magnetic levitation weft insertion device, the main structure includes a base 3, an electromagnetic assembly 1 installed on the base 3, and an electromagnetic controller 2 for controlling the power on and off of the electromagnetic assembly 1. The electromagnetic assembly is composed of an electromagnet coil 11, a magnetically conductive column 12 and a mover weft insertion sheet 13; wherein the number of the electromagnet coil 11 and the magnetically conductive column 12 is designed to be 8 groups, and they are arranged in a straight line on the base 3 , The mover weft insertion piece 13 is erected on the top of the electromagnet coil 11 through the magnetic conduction column 12 . Each electromagnet coil 11 is composed of an internal iron core and a coil wound around the periphery of the iron core; each magnetically conductive column 12 is composed of a pair of oppositely arranged columns 12a, and the magnetically conductive column 12 is made of an...

Embodiment 2

[0033] The difference between this embodiment and the first embodiment is that the mover iron piece 13b of the mover weft insertion piece 13 adopts a prismatic shape.

Embodiment 3

[0035] The difference between this embodiment and Embodiment 1 is that three mover iron pieces 13b are evenly distributed on the wear-resistant casing 13a of the mover weft insertion piece 13, and the shape of the mover iron pieces 13b is hexagonal The two sides of the mover iron piece 13b have gradually changing arc segments or straight line segments, thereby forming a gradually changing air gap between the mover iron piece 13b and the end of the column to provide magnetic power. The energization mode of the electromagnetic controller 2 in this embodiment is that each adjacent three groups of electromagnet coils are energized alternately in order to meet the normal travel of the mover weft insertion piece.

Abstract

The invention relates to a magnetic suspension weft insertion device with variable magnetic resistance. The magnetic suspension weft insertion device is characterized by comprising an electromagneticassembly and an electromagnetic controller; the electromagnetic assembly comprises electromagnet coils, magnetic conduction columns and mover weft insertion pieces; the electromagnet coils and the magnetic conduction columns are linearly arranged and are matched in arrangement number, and each electromagnet coil is composed of an inner iron core and a coil wound around the periphery of the iron core; the tops of the magnetic conduction columns extend oppositely to form a horizontal magnetic suspension track; each mover weft insertion piece is composed of an abrasion-resistant shell and a moveriron piece embedded on the abrasion-resistant shell; the electromagnet coils are clamped in the middles of the magnetic conduction columns, and the two ends of the iron core of each electromagnet coil and the magnetic conduction columns form an integral forming structure or are connected in a close contact way without air gaps. According to the magnetic suspension weft insertion device, acceleration and deceleration movements of the weft insertion pieces are driven through the magnetic resistance change, and thus front and back movements of the weft insertion pieces are controlled. The moverweft insertion pieces can be designed as weft feeders and weft receivers as required, and the delivery between fed wefts and received wefts is formed in the middle of a weaving machine.

Description

technical field [0001] The invention relates to a weft insertion device of a loom, in particular to a magnetic levitation weft insertion device of a loom, and belongs to the technical field of textile machinery. Background technique [0002] At present, the looms on the market can be divided into two categories: shuttle looms and shuttleless looms according to the different weft insertion methods. Shuttle looms are looms that use traditional shuttles (wooden shuttles or plastic shuttles) for weft insertion; shuttleless looms have a variety of weft insertion methods, mainly including rapier, jet (air jet, water jet), sheet Shuttle, multi-shed (multiphase) and weaving. Shuttle looms are often projected back and forth repeatedly due to the large size and weight of the shuttle, which brings about a series of problems such as large vibration, high noise, slow speed, and low efficiency of the loom. However, the weft insertion methods of the shuttleless loom have their own disa...
