SU1440970A1 - Apparatus for forming fibrous sliver in carding machines - Google Patents

Abstract

A sliver guide comprises a fibre guide element (9) which is closed on at least three sides, and is disposed, in the operating position, above the line of connection between the take down roller gap (17) and the supply roller gap (18) and by means of which the fibre fleece is guided approximately perpendicularly upwards from the take down roller gap. This locates the fleece very close to the output side of the take down rollers and maintains the edge zones of the fleece on the fibre assembly in a reliable manner. Obstructions move the guide and switch off the machine. <IMAGE>

Description

The invention relates to the textile industry.

A similar device is known (French Patent No. 23840415 Cl, D 01 G 14/46, 1978), where there are a pair of outgoing shafts, a pair of feed shafts and a carrier of fibrous tape located between them with a guiding element with a funnel-shaped part closed on three sides and ribbon sealing funnel.

This device is not very reliable in operation and has low operational properties.

The purpose of the invention is to improve performance and reliability.

FIG. 1 shows the proposed device; FIG. 2. - drove a fiber tape, front view.

The device contains a carding drum 1 with an ash blade 2 and a removable drum 3, behind which a pair of 4 exhaust shafts 5 and 6 is located. Shaft 6 is located above and shaft 5 below it below. On the axis 7 of the lower shaft 5, the carrier of the fiber strip 8 is mounted for rotation. It contains a guide element with a funnel-shaped part 9 closed on three sides.

Part 9 is located in the middle of the upper part of the guide element, which is made in the form of a trough-shaped plate 10. Instead of part 9, a conventional rifle can be used, and instead of plate 10, a wire clamp that carries part 9. Plate 10 has fins 11 .

The carrier 8 may be rotated from operating position 12 to service position 13 and vice versa. A spring-loaded stop pin 14 is installed on the frame to stop the plate 10. To rotate the plate 10, a lever 15 is provided. In the working position the plate presses the limit switch 16 connected to the main drive of the machine (not shown), In the working position 12 drove its guide element 8 is above the connecting lip between the tip of the 17 exhaust shafts and the tip of the 18 feed va

fishing, i.e., above the plane passing between the tip of the discharge and supply shafts, above the upper shaft 6 of the upper pair 4, In the service position 13, the guide element is located behind

a connecting line 19 of the exhaust shafts -4 directly in front of the belt-sealing funnel 20. Behind the funnel 20 are a pair of feed shaft 21 and 22

The device works as follows.

When the machine is running, the web 23 comes from the drum 1 to the removable drum 3 and is removed by a pair of exhaust shafts 4. In the normal operation of the head drum, the carrier 8 is in the working position 12, therefore the web 23 goes almost vertically upwards after the exhaust pair 4 to the guide member in its part 9, where it is converted into fiber tape 24, which then flows through the funnel 20 to the pairs of feed rolls 21 and 22. In the case of breaks, fiber accumulates in the area of the tray-shaped plate 10, she is turns, stops acting on switch 16 and the machine stops. The plate 10 is rotated into a plane passing through the sting of the discharge and supply shafts, due to its installation on the axis. When re-laying the fibrous tape, the carrier 8 rotates in position 13, Formula 1 and 1, the device for forming a fibrous tape on carding machines, containing a pair of ejectors. Pairs of feed rolls, located between them, drove a fibrous tape, having a guide element with a funnel-shaped part closed on three sides, and a tape sealing characterized by

funnel,

By the fact that, in order to improve the operational properties and increase the operating reliability, the guide element of the carrier of the fiber tape is located above the plane passing between the sting of the discharge and feed shafts, the upper shaft of the high-speed pair,

2, the device according to claim 1, characterized in that the guiding element of the carrier of the fibrous tape is made in the form of a tray-shaped plate mounted on an axis with the possibility of its rotation into a plane passing through the sting of the output and feed shafts The funnel-shaped part is located in the middle of the upper part of the plate.

Claims (2)

Claim 1. A device for forming a fibrous tape on a card machine, comprising a pair of exhaust shafts, a pair of feed shafts, a carrier of a fibrous tape located between them, having a guide element 4Q with a funnel-shaped part closed on three sides, and a tape sealing funnel, characterized in that, with In order to improve operational properties and increase reliability, the guide element of the carrier of the fiber tape is located above the plane passing between the tip of the exhaust and feed shafts, above the upper shaft of the exhaust oh couples. 2. The device according to claim 1, characterized in that the guide element of the carrier of the fibrous tape is made in the form of a tray-shaped plate mounted on an axis with the possibility of its rotation into a plane passing through the tip of the exhaust and feed shafts, and the funnel-shaped part closed on three sides is located in middle of the top of the plate.
