A reed moving raising mechanism

Abstract

The invention relates to a reed moving and fluffing mechanism.An eccentric drive mechanism is hinged to one end of a power rod drive connection rod, the other end of the power rod drive connection rod is hinged to one end of a fixed included angle reserving rod set, the other end of the fixed included angle reserving rod set is hinged to one end of a sley sword drive connection rod, the other end of the sley sword drive connection rod is hinged to one end of a sley sword drive lever, and the other end of the sley sword drive lever is connected with a sley sword adjustable fixed included angle; the non-end point of the fixed included angle reserving rod set is hinged to one end of an adjustable fixed included angle control rod set, the middle of the adjustable fixed included angle control rod set is movably hinged to a loom frame, the other end of the adjustable fixed included angle control rod set is hinged to one end of an eccentric connection rod, the other end of the eccentric connection rod is connected with a numerical control execution mechanism, the numerical control execution mechanism is provided with an original point signal acquisition mechanism, and both the numerical control execution mechanism and the original point signal acquisition mechanism are connected with a control electricity box.

Description

technical field [0001] The invention relates to a loom, in particular to a reed moving raising mechanism of the loom. Background technique [0002] In the existing reed moving towel loom, in order to meet the requirements of different pile heights, it is necessary to change the swing angle of the reed to achieve long and short beating. For example, a reed moving air jet towel loom with a patent number of 201420200844.6 adopts a fixed angle The first and second pendulum rods drive the sley legs, and the rotation points of the first and second pendulum rods with a fixed angle are changed by the looping crankshaft to drive and control the sley legs to achieve different angles of rotation and beat-up of the sley legs, but the first 1. The second pendulum itself fixes the included angle, and its connection point is used as the rotation point to control the rotation period of the coil crankshaft. When controlling the coil coil cycle, the rotation axis of the coil crankshaft is mis...

AI Technical Summary

Problems solved by technology

[0002] Existing reed moving towel looms, in order to meet the requirements of different terry fluffing heights, need to realize long and short weft beating by changing the swing angle of the reed, such as a kind of reed moving air-jet towel loom with patent No. 201420200844. The first and second pendulum rods drive the sley legs, and the rotation points of the first and second pendulum rods with a fixed angle are changed by the loop crankshaft to drive and control the sley legs to achieve different angles of rotation and beat-up of the sley legs, but the first 1. The second pendulum itself fixes the included angle, and its connection point is used as the rotation point to control the rotation period of the coil crankshaft. When the coil coil cycle is controlled, the rotation axis of the coil crankshaft is misaligned with the hinge point of the first and second pendulum rods on the coil crankshaft. The force of the pendulum at the rotation point is large. In the long-term and high-speed beating environment, the service life of the pendulum is short, which affects the stability and safety of the loom.
