Description

FIELD OF THE INVENTION This invention relates to spinning production of the textile industry, in particular to devices for removing fiber from a combing drum of a textile machine, for example a carding machine, when high fiber parallelization is required during pneumatic removal of fiber.

The purpose of the invention is to improve the quality of the resulting fibrous product.

In FIG. 1 schematically shows a device for removing fiber from a combing drum (side view); in FIG. 2 - the same, top view; in FIG. 3 is a section AA in FIG. 1.

The device for removing fiber from the combing drum includes a combing drum 1. mounted rotatably, for example, clockwise (the main drum of the carding machine or the combing drum following it in the technological process), and a pneumatic chamber 2 located over the entire working width the machine along the generatrix of the combing drum 1 and hermetically connected to the suction nozzle 3. The chamber 2 is located vertically inside the skeleton of the machine with the possibility of feeding the filmed fiber to the horizon the upper upper branch of the mesh conveyor 8, and the air velocity in the removal nozzle at the fiber removal point is higher than the rotation speed of the combing drum 1 (or the combing drum 1 rotates clockwise, marked in Fig. 1, in the opposite direction of air movement), which ensures fiber removal from the combing drum 1, covered with an all-metal serrated tape from the back of the tooth nape. The suction nozzle 3 is constricted and

connected to the fan 4, connected to the electric motor 5 by means of a belt drive with pulleys b and 7. The upper branch of the mesh conveyor 8, leading the fiber formed on it and in the form of a tape across the axis of the carding machine from the skeleton of the machine, is mounted with the possibility of movement at the bottom of the nozzle. At the end of the exit of the upper branch of the conveyor from the skeleton of the machine, there is a removable mechanism for the tape 9, made in the form of a system of horizontal and vertical rollers, for example, two pairs of horizontal rollers 10 and 11 and one pair of vertical rollers 12 that remove fiber from the mesh conveyor 8 and form into the tape. The removable mechanism 9 may be provided internally with funnels 8 and 14, helping the rolls to form the tape. The removable mechanism 9 is connected to the tape layer (not shown in the drawings) and can be equipped on this way with a device for controlling the breakage of the tape entering the head of the tape layer, for example a reed switch .. The side walls of the lower part of the fiber-removing nozzle 2 form metal conveyors 15 and 16, the axes of which are inclined in a vertical plane, and the internal branches move in the direction opposite to the movement of the output mesh conveyor 8 (FIG. 3), the conveyors being installed with the possibility of contact with; their smooth metal Rear ends of the second surface moving with the air in the chamber 2 of fibers removed from the opener ies drum 1, and the stretching in the transverse direction (parallelisation before forming them on a moving conveyor .setchatom 8).

A device for removing fiber works as follows.

A fiber combed by a carding machine, usually divided into individual fibers or small fiber complexes, from which the main mixture of litter and small fibers are removed, for example, the receiving unit of the carding machine and the main drum unit with combing organs (flakes, segments or working pairs of rollers) enters the combing drum 1, mounted for rotation (the main drum of the machine or the last drum of the machine that received this fiber in the course of the product), for example, clockwise (possible of movement and counter-clockwise) with Fiber opener drum 1 is removed pneumatic chamber nozzle 2 located across the working width of the machine along a generator opener drum 1 "due to the fact; that from it a nozzle 3, hermetically connected to the chamber 2, and a fan 4, connected to the electric motor 5 by a belt drive through pulleys b, 7, suck air. The fiber, shot by a camera 2, located vertically inside the skeleton of the machine, is fed onto a horizontal branch (upper) of the mesh conveyor 8, whereby the fiber is transferred by its cross section perpendicular to the flow and is formed on the mesh in the direction perpendicular to the axis of the carding machine, i.e. parallel to the generatrix of the combing drum 1. Moreover, it is formed mainly with a parallelized arrangement of fibers perpendicular to the axis of the machine, and it is in this direction that it is brought to the mechanism for removing the webs 9, High-quality parallelization of the fibers in the formed belt on the mesh conveyor 8 is facilitated by vertical conveyors 15 and 16 (Fig. 2), whose axes are inclined in the vertical plane and the inner branches moving in the opposite direction of the output mesh conveyor 8. In this case, the rear ends of the fibers moving with air in the removal nozzle 2, removed from the combing drum 1, are in contact with the smooth metal surface of the conveyors 15 and 16, also pulled in the transverse direction, i.e. d forming them on a moving conveyor belt 8. Next, the rear pair of rollers 10 detachable mechanism 9 (the upper roller of which may be rubberized and the bottom. - corrugated) removes the formed tape from the mesh conveyor 8. Moreover, the upper roller of the .1.0 pair is pressed against the lower by adjustable springs acting on its lateral supports (Figs. 2 and 3). A vertical pair of rollers 12 seals the tape in a horizontal plane, and the front pair 12 helps to further seal before feeding the tape to the tape head (not shown in the drawings). Funnels 15-16 help the rollers to form the tape and can be located inside the removable mechanism 9. The tape on its way from the removable mechanism 8 to the tape stacker can be controlled, for example, by a reed switch of the tape break control device.
