Description

The subject of the invention is a base sizing machine, in which a device is used to install and brake warping rollers using brake shoes, a glue trough with a mechanism for immersing the base in dressing, steam from impellers, a drying device with pressure boxes and nozzles for blowing the mountain base with air, an electric drive with electric machine amplifiers and a tachogenerator, and a navival device.

The proposed machine, in comparison with the known similar machines of the same designation, allows to increase the speed of sizing, automate the sizing process and improve the quality of the base.

The design features of the machine are as follows.

Brake pads are equipped with rods, at the ends of which are mounted nanaravnyh rollers that interact with a flexible cable; the load lifted by the action of compressed air through the pneumatic relay when the machine is started is suspended to the free end of the cable.

Adjustable levers are used in the braking device of the machine, the free ends of which are provided with guide rollers that interact with the cable.

The bearings of the upper squeeze shaft are connected by means of rods to pistons installed in cylinders filled with oil and separated by diaphragms into which compressed air is supplied.

The drying device is made in the form of two chambers successively along the drying process, consisting of separate sections placed one above the other, in which the swivel rollers are installed for the two branches of the base; pressure boxes with nozzles in one chamber are shifted vertically relative to pressure boxes with nozzles in another chamber.

A navival device is used in the machine, which is designed in the form of telescopically supported support centers, which are telescopically pulled out with the help of compressed air, which support and clamp the clamping of the pinch as it rotates.

FIG. 1 shows a general schematic diagram of the machine; in fig. 2-diagram of the assembly of warp rollers

brake device; in fig. 3 - wringing device; in fig. 4 is a diagram of a navival device; in fig. 5 is a diagram of a drying device.

The machine includes the knot / warp rollers, the knot // of the roll shaft, the knot /// - the sizing part, the knot IV - the drying device, the knot V - the winding part, the knot VI - the drive, the hind VII - the electrical part and the vapor-pneumatic part .

Warping rollers / for rolling are mounted on racks, made in the form of cast-iron frames, arranged on the sides of the warp rollers and fastened by ties. The frames are assembled from individual elements at the rate of one frame on two warp rollers; the frame elements are fixed to the floor with the fundamental bolts 2. The knuckles of the warping rollers / are laid through the guides 5 racks onto two roller bearings. Warp rollers pulleys on brake pads 4.

In order to brake NIN again on the rollers at the same time during automatic braking and when the machine is stopped, the brake pads 4 are equipped with rods 5. At the ends of the rods, the guide rollers 5. are curved around the cable 7. By the free end of the cable there is a suspension 8 suspended up and down under the action of compressed air when starting the machine. The load 8 is located on the plate, attached to the rod 9 of the piston 10 of the pneumatic cylinder.

Regulation of the braking force of the 1st warp roller by changing the angle of coverage of the guide rollers 6 by the cable 7 is achieved by using adjustable arms //, on the free ends of which there are guide rollers 12 skirted by the cable 7.

When the piston 10 is moved down by the action of the load 8, the cable pulls up, the rods 5 move upwards, as a result of which the brake pads: 4 retard the warping rollers. When the compressed air is launched into the pneumatic cylinder through the nozzle 13, the piston 10 moves up, the cable 7 weakens and the rods 5 with the pads 4 lower, release the warping rollers.

The deceleration of the rollers is controlled automatically by a pneumatic relay included in the control panel of the main control panel.

The yarn is squeezed out by a squeezing device located in the dressing parts of the machine with squeezing shafts 14 and 15.

To regulate the pressure between the squeezed shafts and to "absorb the vibration of the upper shaft 14 at a high rate of sizing, the pods 16 of the upper squeeze shaft are connected via rod 17 to the norm 18. The latter are installed in cylinders 19 filled with oil and separated by diaphragms 20 used as dampers . The movement of the pistons 18 is carried out with compressed air supplied in the cylinder cavities.

By adjusting the air pressure in the cylinder cavity, the pressure acting on the shaft 14 is established, and hence the degree of spinning of the base after passing it through the adhesive trough of the sizing part of the machine.

To facilitate the weaving of the weaves and to remove them after winding, a navival device was used, consisting of two telescopically extendable support centers made in the form of penoles 21 and 22, between which weave 23 was placed.

When compressed air is supplied through the nozzle 24 into the cylinder 25, the porosity 2o pushes the foam 21, fixing the YING one tweez of the weaver. At the same time, the compressed air supplied through the nozzle 27 acts on the piston, which advances the foam 22, which secures the other spike of the weaving fabric. The rotation is carried out with the help of a finger from a pinion mounted on the foam.

For removal, the compressed air is directed through nozzles 28 and

29, as a result of which the pistons move in the opposite direction and are free from fastening.

The drying device is represented by two chambers L and B, installed successively one after the other in the course of the suipcha process.

Chambers A and B have several separate sections a, one above the other, and supplied with pressure ducts 30 with nozzles arranged in a staggered order, with heated air / direction of movement of which is shown in the drawing by arrows.

In order to ensure that the base is blown with hot air from its two sides, chambers A and B are equipped with directional rollers 31 and rotary rollers 32, which are rotated from the actuator of the actuator.

Pressure tanks 30 with sleepers. In chamber B are replaced vertically, approximately by half of the diameter of rol1-1KOV 32 in respect of pressure boxes in chamber A.

Between the chambers L and in the upper part: supgi.; Or another device, three guide rollers are mounted, of which the middle roller is compensated. The purpose of these ROLLERS015 is to create a support for the base of a large length of 1N: when moving it from the camera / 1 to camera B.

Ospova 33 enters in the direction of the arrow C in the lower part of chamber A and makes a zigzag movement through the sections of this chamber, shifting into the BepXHKiio part of the chamber; in each section, only one side of the base is exposed to air blowing. From the chamber L, the base enters the chamber -B, in which the other, the reverse side of the base, is subjected to air blowing. Thus, when the base is passing through the drying device, it turns from one side to the other, which speeds up the drying process.

In the scheme of the electric drive of the machine, with the aim of creating an automatic speed control and maintaining a constant tension base.

electromechanical usi connected / plug with tachogenerator.
