Description

Embedded direct-drive jacquard machine head Technical Field The utility model relates to the technical field of jacquard heads, in particular to an embedded direct-drive jacquard head. Background At present, jacquard has important position in textile industry with the advantages of high working efficiency, proper cost performance and the like in the textile industry of China. With globalization of international trade, export and production of jacquard machines have been greatly developed. The power system of the jacquard mainly depends on a motor to control two main shafts to rotate through gear transmission so as to realize the up-and-down swing of a first swing rod and a second swing rod which are respectively driven by the two main shafts to finish the jacquard function. Disclosure of utility model The utility model provides an embedded direct-drive jacquard machine head, which has the advantages of high transmission efficiency, low energy loss, stable swing precision and low noise. The utility model provides an embedded direct-drive jacquard machine aircraft nose, which comprises a frame, the inside tubular first main shaft that is equipped with of frame, first swinging arms swing of first main shaft drive, the inside second main shaft that is equipped with of first main shaft, second main shaft drive second swinging arms swing, first cam swing arm is connected to first main shaft axial, first cam swing arm cooperation first cam, the hole lug connection motor main shaft of first cam, second cam swing arm is connected to second main shaft axial, second cam swing arm cooperation second cam, the hole lug connection motor main shaft of second cam, the permanent magnet motor rotor of permanent magnet has been inlayed in motor main shaft periphery connection, permanent magnet motor rotor periphery is equipped with the stator, motor main shaft axial one end is equipped with the encoder, the other end is equipped with the impeller. The motor main shaft that this kind of embedded direct drive jacquard machine aircraft nose passes through permanent magnet motor rotor and connects directly reads motor main shaft rotational speed through the encoder, and control drive first cam, the synchronous rotation of second cam realize the synchronous technical effect of swinging from top to bottom of first cam swing arm that first main shaft is connected and the synchronous vertical hunting of second cam swing arm that second main shaft is connected, avoid reducing transmission parts such as gear and reduced equipment drive energy consumption, improved the rotation precision of first cam swing arm, second cam swing arm.
