Description

The present invention relates to scaffolding controllers with a canvas of a carding machine that provide a uniform supply of cotton to the machine. At a distance from the feed cylinder, a cylinder is placed that extends over the entire width of the table. Above the cylinder there is a row of rollers, the raising and lowering of which is fixed by a lever mechanism, the resulting movement of which by means of levers sets, depending on the thickness of the canvas, movable rods located along the periphery of the rotating disk. These rods are used to move the two shoulders of the lever connected to the conoids.

In the schematic drawing of FIG. 1 is a sectional front view of a feed control with a carding card; FIG. 2 - view from the left side; FIG. 3 - the resulting lever mechanism in the section.

Adjusting the supply of an equal amount of cotton at each time point is carried out on the carding machine using the following mechanism. On the feeding table 1 of the card machine, in front of the feeding cylinder 2, an intermediate cylinder 3 is placed, which has a permanent gearing with the feeding cylinder. On the cylinder 3 are free metal rollers 4 close to each other across the entire width of the machine. The rollers are enclosed in a box in which the lever mechanism 5 (Fig. 3) is located, which is a lever system that reduces all the movements of the rollers vertically into one resultant movement. The canvas feeding the machine passes between cylinder 3 and rollers 4. All irregularities of the canvas cause the rollers under which it passes to move vertically inside the resultant mechanism 5 (Fig. 3). Since the thickness of the canvas layer is in direct proportion to the amount of cotton fed to the machine, in order to evenly feed the machine with a thin layer, it is necessary to give a greater rate of its entry into the machine than with a thick one, i.e. for uniform feeding of cotton into the machine, the condition 2- - const should be observed where v is the feed rate of the feeding cylinder and q is the cross-sectional area of the canvas. The change in feed rate, depending on the thickness of the canvas, is carried out as follows. The change in the thickness of the canvas is fixed by the lever mechanism 5 (Fig. 3), the resulting movement of which is transmitted by a loaded lever 6 to the lever 7, which, having a movement, acts on the metal rods 8, the disc 9 having a circumferential speed, p &; a clear speed of the intermediate cylinder 3 (Fig. 1 and 2). The rods 8, set by the lever 7 in a certain position corresponding to the given section of the canvas, upon leaving the lever, remain in the set position, rotating with the disk 9. As they pass, the distance between the clamps of the intermediate cylinder 3 and the nutrient 2 or rather, from the clamping by cylinder 3 to the edge edge BHytpeHHefi, i.e. at the moment the layer corresponding to each rod enters into the machine, the rods 8 fall under the action of the spring which fits tightly to them and thereby prevents them from moving along its axis. At the same time, the rod 8 begins to come into contact with the rod 10, which by the spring 16 all the time is pressed against the rods 8 of the disk 9 and under their action moves back and forth along its axis. These movements of the rod 10 correspond sectically to the movements of the lever 6, only with being late against its action, just at the time of the journey of the corresponding section of the canvas under the action of the feeding cylinder. Upon leaving the clamping spring 16, the rods 9 become in the appropriate position, coming into contact with the guide lever 7, the Rod 10, moving under the action of the rods 8, causes the double-arm lever 11 to swing, the slot of which includes the pin of the rod 10 the other end is connected to the belt slider 12, which moves the belt on the hyperboloidal drums 13, from

the lower drum has a constant speed, and the upper variable, depending on the position of the belt on the drums (Fig. 1 and 2). The lower conical drum receives rotation through gear 15 from the major shaft 14. The upper conical drum transmits movement to the feed cylinder 2 by means of a screw and helical gear. Thus, the resulting swing of the lever 6 reflects the movement of the belt along the hyperboloidal drums, which in turn gives change in the speed of the feed cylinder 2, i.e. the condition of uniform feeding of cotton into the machine is realized.

The subject matter of the invention.

A card feed regulator consisting of a lower roller, a series of upper rollers and a resultant lifting of the latter lever mechanism connected to the outlet of the hyperboloidal drums, characterized by the use of a rotating disk 9 fitted with movable rods 8 positioned on its periphery, installed in a specific position , depending on the thickness of the canvas, by means of levers 6 and 7, pivotally connected to the resulting lever mechanism 5, which rods 8 serve to move the pressing by the action of the spring 16 of the rod 10, the finger of which enters the slot of the end of the lever 11, the other end of which is connected to the belt branch of the hyperboloidal drums. to the author's testimony of V.
