Description

one

The invention relates to the textile industry, in particular to cotton ginning, and can be used in the ginning of fine-fiber raw cotton.

The purpose of the invention is to increase the reliability of the available gin in operation by maintaining a constant amplitude of oscillation of the breaker plate with a change in the diameter of the working drum.

In FIG. schematically shows the proposed gin; figure 2 is the same, top view; figs. 3 and 4 show details of the gin baffle body, variants of mutual arrangement in operation; FIG. 3 shows the assembly for connecting parts of the breakaway body, axonometrics; 6–8 are a kinematic diagram of a four-hinge mechanism.

The lapie gin contains a working drum 1 with a fixed knife 2 installed in the housing, and a fender body made in the form of a fender plate 3 with a working edge facing the drum surface and means for its oscillatory movement J having a double-arm lever 4 (there may be two each end side of the drum), mounted with the possibility of swinging from the vibrator 5 on the axis of the drum 1, the yoke 6, hingedly connected with the baffle plate 3 on the side of its non-working section, and the support bar for the plate 7 rigidly connected by adjusting screws with the plate 3 and the hinge. connected to the drive lever 4

- When the gin is working, the work drum sucks the cotton fiber under the baffle plate 3 and the fixed knife 2, and the squeezing process lasts until this cotton is pressed into the working edge of the baffle plate. Due to the oscillating movement of the drive lever 4 connected to the vibrator 5, the baffle plate 3 moves relative to the fixed knife 2, bouncing off the seeds extending to the edge of the latter. The fibers cut off from the seeds are carried away by the drum surface under the knife and out of the machine. The presence of the rocker support for the plate in the form of a beam 7 and the rocker arm 6 allows for a complex movement of the fender plate: during movement: from the knife edge 2 the plate rotates with the rocker support

 at some angle, since the yoke keeps its non-working section, while the angle of rotation of the baffle plate is inversely proportional to the ratio

The 5 lengths of the baffle plate 3 and the working arm of the lever 4. The angular rotation of the baffle plate allows to separate the ginned seeds at positions remote from the edge of the knife 2 when

0 the bond between the fiber and the knife is minimal, which excludes their pinching in the ginning area, and the reverse rotation of the plate at the knife edge improves the grip of the fibers due to

15 wedge givani.

Adjusting the position of the baffle plate relative to the surface of the drum is made by moving it along the beam 7, thanks to the gift of adjusting grooves and displacement of the connecting hinge of the beam along the lever 4. the angle of rotation of the fender plate, for which it is necessary to change the working lengths of the bar 7, the fender plate 3 and the lever 4, and the smaller the value of their ratio 30, the greater the angle of rotation of the fender plate and accordingly oscillation .amplituda its working edge. Vibrator. 5 provides the swinging movement of the lever 4 (link J on

J, Fig. 6) of the support link consisting of the swinging bar 7 and the fender plate 3 (link b) and the rocker arm 6 (link c) / and at the hinge 0 a four-star break occurs; when

40. The link moves with the lift of the hinge 0 (0. moves counter-clockwise), the link b, composed of a swinging beam and a baffle plate, moves clockwise, rotating around the hinge 0.

The use of a four-hinged mechanism in the proposed breaker shaft allows for an exception.

The need is fulfilled. And a baffle plate with holes, since

50 is turned in antiphase to the lever 4, the working plane of the plate does not interfere with the separation of seeds, and to reduce the inertial loads on the drive of the fender plate. In this case, the baffle plate is technologically activated, since the force of pushing the seeds H into the holes is replaced by their discharge along the swinging plane, and the translational 3. 12442, thoroughly moving it over the surface of the working drum increases the effectiveness of applying vibration. and also eliminates the significant movement of the non-working 5 section of the baffle plate, which reduces the mechanical damage to the fiber and seed. In addition, the reliability of a gin in work is enhanced by maintaining a constant amplitude.

7 and 8) oscillations of the fender plate due to a change (decrease) in the diameter of the working drum due to the wear of its surface. In order to provide a given plate oscillation amplitude, it is necessary to adjust the position of the pivot hinge on the beam lever (point K in Figs. 7 and 8) relative to the working edge of the fender plate.
