Embodiment Construction

[0007] Such as figure 1 As shown, the pipe-type weft detector consists of the weft detector casing (1), the casing cover (2), the photoelectric cell (3), the photoelectric cell connection line (4), the control circuit board (5), the cable (6) composed of. The shape of the casing (1) of the weft finder is the same as that of the pipe piece (see A-A view), and it is formed by one-time pressing, and there is an "E"-shaped groove in the middle G pressing, which is used to accommodate the photoelectric cell connection line and the control circuit board and cables; two round holes with a diameter of d3 are processed on the top of the groove, which are used to install photoelectric tubes (one for the light-emitting tube and one for the receiving tube). The included angle is β to ensure that the reflective point is located on the inner arc surface of the "O" airflow channel of the casing; the two photocells do not expose the "O" shaped airflow channel and are hidden outside the chann...

Abstract

The invention relates to a special conduit sheet type weft finder for a jet loom, which consists of a weft finder shell, a shell cover plate, a photoelectric tube, a photoelectric tube connecting line, a control circuit board and a cable conductor. The photoelectric tube, the control circuit board, the connecting line and so on are hermetically arranged inside the shell the shape of which is the same with that of a conduit sheet, and an inner circular surface of an 'O'-shaped gas channel of the shell is utilized for light reflection, so that the special conduit sheet type weft finder for the jet loom has short reflection path, and is difficult to be interfered, accurate to position and difficult to generate misoperation; and the 'O'-shaped gas channel of the shell of the conduit sheet type weft finder simultaneously has the functions of extending an auxiliary spraying gas channel and improving the flow convergence, so that the special conduit sheet type weft finder for the jet loom is favorable for smooth flying of weft yarns, reduces looped wefts, and improves the product quality of textile fabrics.

Description

Technical field [0001] The invention relates to a pipe-type weft detector used on an air-jet loom, which belongs to a detection device of a new type of weaving equipment for weaving fabrics in a textile mill. technical background [0002] The weft detector is a signal detection device of the air-jet loom, which is used to detect whether the weft yarn flies out of the shed on time during the air-jet weft insertion process. Air-jet looms can be divided into two categories according to their air flow channels: special-shaped reed-type air-jet looms and pipe-type air-jet looms. At present, the existing special-shaped reed-type air-jet looms at home and abroad all adopt the principle of photoelectric detection. After the light emitted by the luminous tube is reflected by the reed, it is received by the receiving tube, and the signal is transmitted to the control circuit board for processing. It is an open type. , the light is susceptible to interference during use, resulting in ...
