Description

Technical Field

[0001] The utility model relates to the technical field of air jet looms, in particular to an edge cutting structure of an air jet loom. Background Art

[0002] The air jet loom is a shuttleless loom that uses a jet of air to pull the weft yarn through the shed. Air is used as the weft insertion medium, and the compressed air jet generates friction traction on the weft yarn to pull the weft yarn through the shed. The purpose of weft insertion is achieved through the jet generated by the air jet. However, the edges of the fabrics produced by the air jet loom are uneven and prone to defects such as burrs. The edges usually need to be trimmed. At present, the cutting blades of most loom trimming devices on the market will become blunt during use, affecting the subsequent cutting quality. Utility Model Content

Mounting seats are arranged on both sides of the frame, a servo motor is arranged on the upper end of the mounting seat, a rotating shaft of the servo motor faces the inner side of the frame, an eccentric wheel is arranged on the rotating shaft of the servo motor, two guide columns are vertically arranged on the frame below the eccentric wheel, a guide hole is arranged on the slider, the slider is slidably arranged on the guide column through the guide hole, a spring is arranged between the lower side of the slider and the frame, and the eccentric wheel Pressing against the upper end of the slider, a blade is vertically arranged on one side of the slider close to the frame, an electromagnetic heating coil is sleeved on the outer side of the blade and the slider, and the electromagnetic heating coil is fixedly connected to the mounting seat through a No. 1 connecting piece. It should be noted here that the slider and the No. 1 connecting piece are made of non-metallic materials, an air pipe is arranged below the electromagnetic heating coil, and the air outlet of the air pipe is directly facing the blade edge, a scraper is arranged on the lower side of the air pipe, and the scraper contacts the blade edge, the air pipe and the scraper are fixedly connected to the mounting seat through a No. 2 connecting piece, the air pipe is connected to the air pump, the jet loom controller is electrically connected to the servo motor, the electromagnetic heating coil and the air pump respectively, and a collecting box is arranged below the blade.

[0005] When the fabric is being conveyed, the edge of the fabric contacts the blade edge between the air pipe and the electromagnetic heating ring, and the jet loom controller controls the servo motor to rotate, and the slider and the blade move up and down through the eccentric wheel and the spring, and when the blade moves to the top, the jet loom controller controls the electromagnetic heating ring to heat the blade edge, and when the heated blade edge moves to the middle, it contacts the excessively long weft thread at the edge of the fabric, causing the weft thread to melt and break, and the blade edge and the slag on it move to the air pipe and are quickly cooled by the high-pressure gas blown out of the air pipe, and then the cooled slag is scraped off by a scraper when moving downward, and the slag and broken weft threads fall into a collection box for collection.

[0006] In order to reduce the inertia of the slider, a weight-reducing hole is provided on the slider.

[0007] The utility model provides an edge cutting structure for an air jet loom, which has the beneficial effect of melting off excessively long weft threads by heating the blade edge, so that the blade edge is not easily worn, the cutting quality is stable, and the service life is long.
