Cotton grasp mechanism adapted for reciprocation bale plucker

Abstract

The invention relates to a cotton picker used in reciprocated cotton picking machine, wherein it comprises cotton picking arm frame (7) combined with rotational tower; under the frame (7), along the length direction, via the longitudinal vibrator (13), two swing rods (16) are parallel suspended; two ends of each swing rod (16) are both fixed with supports (14) for mounting beater; the left and right supports (14) at same end of two swing rods (16) via hinged connectors form the four bar linkage; two beaters (8) are individually arranged in two independent beater cotton picking areas formed by arm frame protect plate (18), inner baffle plate (17) and rib (12), while they are parallel mounted under two swing rods (160 via four bar linkage; and the transmission device for rotating two beaters (8) synchronously at same direction is arranged at the outer end of cotton picker.

Description

technical field [0001] The invention relates to the field of textile machinery, in particular to a cotton catcher mechanism suitable for a reciprocating cotton catcher used in the blowing-carding process. technical background [0002] The reciprocating plucking machine is used in the first process of the combined blowing and carding machine in cotton textile enterprises. The structure of the existing reciprocating plucking machine is shown in Figure 1 and 2, mainly including the turret part 1 and the cotton grabbing arm part 2. Covering tape winding part 3, walking trolley part 4, cotton conveying road and ground rail part 5, and electrical control system 6, etc. At present, the main mechanisms in the reciprocating bale bale machines that are being produced and used at home and abroad, such as ground rails, cotton conveying ducts, walking trolleys, and turrets, are basically the same in structure and application functions, and there is not much difference. There is a big di...

Problems solved by technology

[0006] 1. The single-hand reciprocating plucking machine has only one cotton catching hand, and there is only one grabbing point for fibers, and the captured fiber components are relatively single

Moreover, if the single beater reciprocating plucking machine wants to increase the output and reduce the weight of the captured fiber bundle, it is necessary to increase the speed of the beater and increase the density of the knife teeth, which will inevitably lead to fiber damage and increase the short-lint rate.

[0007] 2. Double thugs reciprocating plucking machine can overcome some shortcomings of single thugs, but because the rotation direction of the two thugs cannot be exactly the same as the walking direction of the machine (as mentioned above), it causes the two thugs to rotate at the same speed, In the case of the same amount of descent (that is, the depth of grasping fibers), the opening and grasping of fibers are different

This setting brings a lot of trouble to the repair, maintenance and replacement of the transmission belt of the mechanism, which is time-consuming and troublesome, often resulting in long downtime and affecting the working efficiency of the entire blowing-carding system
