Description

(B) VALUE JIN.

one

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

The known roller gin contains a working drum, a presser knife and a fender body, which includes a plate in contact with the surface of the drum and having openings for prozhdinzhirovannyh seeds, and a drive for the oscillatory movement of the plate 11 ..

The undoing of the shaft gin, the suctioned organ, is the periodic overlapping of the knife edge, the presence of a gap between the knife, the work roll and the baffle body, the ssuch fiber, which reduces the quality of the fiber and seed.

The purpose of the invention is to increase the productivity of gin and improve the quality of the produced fiber and seeds.

The goal is achieved by the fact that the fender body plate is located radially to the drum, is spring-loaded to its surface and is installed with the possibility of oscillatory movement in the direction perpendicular to the radial one. In this case, the plate is mounted on a lever, freely mounted on the shaft of the drum.

FIG. 1 shows the roller

10 gin; in fig. 2 shows view A in FIG.

The great gin contains a working drum 1, a presser knife 2 fixedly mounted in deck 3, a plate 4 of a breaker body in contact with the drum, a lever 5 connecting the breaker arm with the axis of the drum, a drive 6 for oscillating movement of the plate, a spring 7 of the gate of the breaker organ and device 8, preserving the condition of constant pressure. The k plate of the fender body contains stiffening ribs 9, between which the windows 10 are cut down so that on the side of contact with the drum a strip of width is formed that is commensurate with the seed,

Valicny JIM works as follows.

The working drum 1, rotating in the direction of the arrow (Fig. 1), captures the fiber fibers of the raw cotton and pulls them under the plate 4 and. knife 2. The oscillatory movement of the plate transmitted from the actuator 6 disrupts the connection between the seed and the fiber, and the last drum-knife held by the pair, when separated from the seeds, is carried away from the machine, the seeds being at the edge of the plate until they are completely bare, after which they fall through windows 10,

In order to move in the direction perpendicular to the radial, the baffle body is connected with the axis of the drum by lever 5 so that the shaft of the drum is a hinge link of the swing assembly.

To ensure sufficient rigidity of the plate, the latter is provided with stiffening ribs.

The contact oscillating movement of the baffle body eliminates the influence on the ginning process of the periodic overlapping of the working edge of the fixed knife, since the rebound element is pressed against the surface of the working drum and therefore promotes the gripping and pulling of the fiber under the knife.

The consequence of the constant contact of the fender body plate with the working drum is the elimination of the most important negative factor affecting the quality of the processed wear product,

In the proposed genie, a baffle body is pivotally connected to the shaft of the working drum, and the latter is a wasp. the basic detail of the node ginishing

The bumper body that seizes and prepares for the ginning of raw cotton fibers fundamentally changes the process of fiber separation, transforming the nature of its flow from intermittent to continuous, with

It lasts until the seeds are completely bare in one cycle of staying the bat at the edge of the knife (i.e., with the contact-oscillating rebound, communication with the ginning unit is not lost).

For the ginning are two elements that are equally capable of capturing the fiber (knife 2 Ti

plate k} and not interfering with the filament process, and their interaction contributes to breaking the bonds of the fiber with the seed.

The absence of non-working areas, gaps between the fender and the working drum, regulation of the plate feed depending on the degree of wear of the drum surface, shaking of the voltages and complete exposure

seeds in one treatment cycle provides an increase in gin productivity, a reduction in seed damage, and an increase in fiber quality.
