Description

A device for cottonless cotton combing machines is known, comprising a vertical rectangular section bunker, a chamber located under the bin, in the upper part of which a loosening drum is mounted and in the lower part a mesh drum to form a layer of cotton fiber on it. In the known device, the feed rate of the cotton fiber layer to the take-up drum varies and depends on the layer thickness.

In the device being described, the supply of cotton fiber layer to an attractive drum occurs at a constant speed, which improves the flatness of the layer.

To this end, the front and rear walls of the bunker receive a vibrating movement from the eccentrics, and above the loosening drum, moving grates are horizontally arranged, kinematically connected with suspended vertical shields deflecting the cotton fiber to the front or rear surface of the mesh drum with a roller controlling the thickness of net drum.

The grate bars are hinged at one end, and at the other end they rest on eccentrics that are rotated using a lever system connected to a hingedly reinforced rear vertical shield.

In the modified device, the grate with a fixed rear vertical shield is kinematically connected with a front vertical shield that receives movement through a system of levers from the roller.

FIG. 1 shows a diagram of the device; in fig. 2 is a diagram of a modified device.

The front wall 1 and the rear wall 2 of the vertical bunker, having a rectangular cross-section, are highlighted by the upper ends on the hinges and receive a vibrating motion from the eccentrics 3.

Under the bunker there is a chamber with a loosening drum 4 located in its upper part, and a mesh drum 5 for forming on it a layer of cotton fiber located in the lower part of the chamber.

Between the loosening drum 4 and the bunker, a grate is mounted, consisting of approximately five sections. The grate 6 of this grating, in order to control the size of the immersion of the needle of the drum in the intervals between the grate, one ends mounted on hinges 7, and the other ends rely on eccentrics 8. Eccentric number 119461-2 -

tricks 8 by means of levers 9 are connected to a hinged mounted rear rear flap 10, which, in the vertical plane of the grate, deviates or is lowered in the vertical plane of the grate, and this changes the size of the needles of the drum 4 in between the grates and, consequently, the amount of cotton trapped from the bunker.

The middle grate 1} in each section of the grate is movable in a horizontal plane and at one end through a system of levers 12 is connected with a winding roller 13 mounted on an axis connected by a lever 14 with a hinge 15 and based on the riOBepxity of the mesh drum 5 - Roller 13 controls the thickness of the cotton layer on the drum 5.

A roller cleaner 17 is mounted at the bottom of the fixed wall 16. The other end of the grate 11 is kinematically connected with a pivotally mounted suspended front flap 18, when deflected in a vertical plane, the cotton fiber advances to the front or rear surface of the mesh drum 5.

The cotton from the bunker is captured through the grate by the drum 4 and loosened to be sucked to the surface of the mesh drum 5. The amount of cotton fed to the drum 5 is adjusted by the position of the rear flap 10. The control roller 13 rises or lowers on the drum 5 upon the result is that the front flap is deflected to one side or the other and cotton is evenly distributed on the drum 5.

During device operation, the fiber is fed to the receiving drum of the carding machine at a constant speed.

In the modified device (Fig. 2), the rear flap 19 is mounted stationary, and the control roller 13 simultaneously controls, through the eccentric 20 and the system of levers, the raising and lowering of the grate 21 and the deflection of the front movable flap 18.

Subject invention

Claims (3)

1. A device for cottonless cotton combing machines, including a vertical rectangular section bunker, a chamber located under the bunker, in the upper part of which a loosening drum is mounted, and in the lower part there is a mesh drum to form a layer of cotton fiber on it, characterized in that the purpose of supplying a layer of cotton fiber to the receiving drum at a constant speed, the front and rear walls of the bunker receive a vibrating movement from the eccentrics, and above the loosening drum there is a horizontal The grate bars are kinematically connected with suspended vertical brushes deflecting cotton fiber to the front or rear surface of the mesh drum with a roller controlling the thickness of the layer on the mesh drum. 2. The device according to claim 1, which is designed so that, in order to control the immersion size of the loosening drum needles in the intervals between the grate bars, the latter are reinforced with one end and the other end is supported by lever a system connected to a hingedly reinforced rear vertical shield. 3. Video change of a device according to claim 2, characterized in that the grate bars with a fixed rear vertical shield are kinematically connected with a front vertical shield receiving movement through a system of levers from the roller.
