Description

The invention relates to machines for separating spine and coarse hair from the main mass of wool fiber.

The described Lashina is designed as a fixed feeding table interacting with each other with a hollow feeding corrugated cylinder located at its end with perforated walls; a hollow receiving drum mounted behind the hollow cylinder and covered with a serrate or needle-type headset and also having perforated walls; a combing drum located in the same horizontal plane with the receiving drum, and a bogie roller mounted under the receiving drum, rotating towards it and covered with a needle headset. The cavities of the perforated feed cylinder and the receiving drum are attached to the suction pneumatic system, and inside these bodies, fixed arcuate plates are installed in the fiber removal areas, partially covering the perforations of the walls.

The stationary feeding table is made of two plates arranged one above the other, between which a curvilinear channel is formed for supplying compressed air into it. The output of the channel is directed tangentially to the surface of the receiving drum. The bottom plate is mounted with the possibility of vertical movement.

The lower part of the take-up drum and the baffle roller are enclosed inside a duct under vacuum and having a damper for controlling the amount of air entering it. Inside the duct mounted interacting1, not with the receiving drum and the fender roller jacks.

FIG. 1 shows a schematic machine; in fig. 2 - non-transverse incision of the supply cylinder; in fig. 3 - iops) an incision receiver drum.

The machine includes interconnected stationary feeding table 1, feeding corrugated cylinder 2, receiving drum 3, combing drum 4 and baffle roller 5. Feeding cylinder 2 and receiving drum 3 are hollow with perforated walls. Their internal cavities are connected to the suction pneumatic system and are provided in the fiber removal areas with fixed arcuate plates 6, which block the perforation of the walls in these areas to stop the flow.

The feeding table / consists of two, one above the other plates, between which a channel 7 is formed for supplying air under pressure. To adjust the amount of air supplied, the bottom plate is mounted for vertical movement. The output part of the channel 7 is directed tangentially to the surface of the receiving drum 3.

The impeller roller 5, the combing drum 4 and the receiving drum 3 are covered with a needle or serrate headset. The feed cylinder 2, the take-up reel 3 and the baffle roller 5 rotate in the same direction, and the punching drum 4 in the opposite direction.

The pizh part of the receiving drum 3 and the baffle roller 5 are enclosed within the duct 8, which is under vacuum and has a flap 9 for adjusting the amount of air entering it. Inside the duct 8 mounted partition 10 and interacting with the baffle roller and the receiving drum, the blades 11, 12 and 13, and the blades 12 and 13 vibrate along the axis.

Above the carding drum 4, a suction duct 14 is mounted, near the outlet of which a feed corrugated cylinder 15 and a feed table 16 of the next similar section of the machine are located.

Maschina hermetically sealed housing 17.

The operation of the maschine is carried out as follows.

Wool fiber is tucked between the feed table / and the grooved cylinder 2. Under the action of air dilution in the internal cavity of cylinder 2, the fiber sticks to its surface, and coarse hair, unlike the bulk of the fiber, is less sensitive to the effect of suction, furiously and partially protrudes from it.

Near the receiving drum 3, the flap 6 closes the perforations in the wall of the cylinder 2 and stops the action of the slice in this area, whereby the fiber layer is removed from the cylinder 2 by the headset of the receiving drum 3 and transferred to it. In this case, the layer is loosened and thinned. The bulk of the fiber is suctioned onto the surface of the perforated drum 3, and the axis and the coarse hair, due to their special properties, partially fall out and get carried away by the stream of air leaving the channel 7, partially held on the outer surface of the layer. This part of the coarse hair remaining in the layer is removed from the receiving drum 3 by the impact of the fender roller 5 and the firing blades 11, 12 and 13, and is carried away by the air flow to the duct 8.

Remaining on the receiving drum 3, the main mass of the fiber is removed by the combing drum 4. This is assisted by a flap 6, which overlaps holes in the wall of the receiving drum 3 in the area adjacent to the combing drum.

Under the action of the centrifugal force developed by the carding drum 4, the fiber is discharged from it and enters the suction duct 14, through which air is directed to the feed mechanism 15, 16 of the next similar section of the machine.
