Embodiment Construction

[0021] combine Figure 1 to Figure 3 As shown, a double crank weft guide aluminum block driving device of the present invention includes a main shaft 1, an eccentric 2, a connecting shaft 3, a double crank 4, an aluminum weft guide aluminum block 5, a drive shaft 6, and a connecting block 7 , block 8 and needle bearing 9,

[0022] The main shaft 1 runs through the eccentric 2 and the double crank 4 in turn,

[0023] The connecting shaft 3 connects the connecting block 7 and the double-ended crank 4 by passing through the inner hole on the needle bearing 9, the connecting block 7 and the double-ended crank 4, and the connecting block 7 is connected to the weft-guiding aluminum block 5 through the driving shaft 6.

[0024] When the machine is working normally, when the double-headed crank 4 drives the connecting block 7 to reciprocate up and down at high speed

[0025] The resulting shock load acts in balance on the two needle bearings 9 on the double crank 4 . In...

Abstract

The invention discloses a double-end crank weft guide aluminum block drive device which comprises a main shaft, an eccentric block, a connection shaft, a double-end crank, a weft guide aluminum block, a drive shaft, a connection block, sealing blocks and needle bearings, wherein the main shaft sequentially penetrates through the eccentric block and the double-end crank, the connection block is clamped between two sides of a protruding end of the double-end crank, two side surfaces of a joint of the protruding end of the double-end crank and the connection block are respectively provided with a set of needle bearings provided with the sealing blocks, the connection shaft is used for connecting the connection block with the double-end crank through penetrating through the needle bearings, the connection block and an inner hole of the double-end crank, and the connection block is connected to the weft guide aluminum block through the drive shaft. The invention is applied to devices special for spinning and light industry profession, and prevents the bearings on the crank from being frequently damaged due to the use of the double-end crank so that a weft drive device and a warp drive device work and operate more stably, thus the quality and the stability of a machine are improved, the service life of the machine is prolonged, the working efficiency of the device is increased, and the maintenance cost of the device is reduced.

Description

technical field [0001] The invention relates to the field of textile machinery, in particular to a double crank weft guiding aluminum block driving device. Background technique [0002] The drive of the existing weft guiding aluminum block mainly utilizes eccentrically driven iron single-head crank to move, and utilizes connecting bolts to connect the single-head crank and the connecting block to drive the weft guiding aluminum block to reciprocate up and down. [0003] Because the crank is only stressed on one side when the single-head crank is connected with the connecting block. When the machine is working normally, the mechanism of this part is reciprocating up and down at high speed, so it will generate a large impact load. Thereby it is easy to make the needle roller bearing installed on the crank be damaged due to the influence of larger impact force, and the dismounting and installation of the bearing on this crank are very inconvenient again. The connecting bo...
