Description

one

A well-known line for the manufacture of a nonwoven material comprising a pile of parallel-installed carding machines with a web converter and a common backup conveyor.

In the famous Linny, the semi-finished product at intermediate operations: rolling and laying cotton from card machines to obtain a material of a given thickness, transferring duplicated canvases to the conveyor of a universal scrolling machine, acid and shaft machine, to a device for cutting a sheet, is done using manual labor, which is a very laborious process.

In order to increase productivity, the proposed production line is equipped with a continuous sealing machine behind the duplicating transnorter, a tiled loading machine, a multi-shaft shaft reversing machine and devices for cutting and removing the nonwoven material, while between the passing machines and the batch machines the material length compensators are located control sensors, and the multi-shaft axle machine is equipped with a command device for communicating work rollers and reversing motion outcoupling conveyor, and for

for rational use of areas, the production line is equipped with iris tools for bezelless rotation of the web by 90 °, consisting of a conveyor belt and located on it at an angle of 45 ° to its shaft axis, receiving and lifting points, them to the grid graters and roll bars that are installed in front of the tiled sheet machine .

FIG. 1 shows the proposed production line, side view (deployed in one lnnnyu); in fig. 2 - the same view in Ylan; on fng. 3 is an attachment for the non-return rotation of the web; a) with a left turn, b) with a right turn.

The continuous line contains a group of napa.filno installed carding machines 1 with a converter 2 braces. Each combing machine is equipped with a hopper 3 for a self-weighing 4. The hopper is a chamber equipped with a scatterer of incoming fibers, a cargo conveyor 5, a fiber grab with needle shield 6 with a baffle and level sensors - the upper 7-down 8 and a load-level sensor 9 of the gravity load 4. Transducer 2 lanes consists of m transmitting conveyor 10 and two mobile transnorters - room 11 and folding cotton 12.

To receive the fleece from the combing machines and transferring the canvas, there is a duplicating plank conveyor 13, which is located along the front of the combing machines and receives from the general drive 14, equipped with a speed variator and transfer, its movement located behind the conveyor 13 through the sealing machine 15, consisting of two belt conveyors arranged one above the other, and mite 16 of the lower conveyor is located above the sub-pair (the perforated plate 17 and covers the compaction pipe 18). The tape 19 of the upper conveyor The tube passes over the lower transnorter belt 16 under the pre-compaction plate 20 and under the sealing concave plate 21 above the drum 18. The articulated plates 20 and 21 are interconnected and they are reciprocated in opposite directions with oscillatory movements of the drum. driven through a crankshaft gear 22. The drum and slab are hollow, steamed and provided on the surface with grooves directed along the semi-finished product.

A transmission conveyor 23 or, for rational use of space, a device 24 for unsupervantly turning the web to the left or right at an angle of 90 °, consisting of conveyor 25 and disposed at 45 ° freely rotating in supports a rotary shaft 26, receiving and adjacent to the conveyor guide grating 27 and a pair of rollers 28, installed in front of the pltoptochnoy mask 29, which consists of a periodically moving floor conveyor 30 the product, the steaming plate 31, the bottom 32 and the top 33 of the loading plates and the upper belt conveyor 34. The upper plate 33 is predominantly in circular motion for compacting the semifinished product.

A locking acid machine 35, consisting of a bath 36 with an acidic solution, two conveying drums 37, and a guide roller 38 and pressing rollers 39, is installed behind the loading machine 29.

At the same time between the continuous sealing machine 15 and the periodic intermittent lashing machine 29, as well as between the last and passing acid machine 35, there are compensators for the semi-finished product, respectively 40 and 41, made in the form of a shaft, in which the control sensors are mounted: but at the top level of the photodetector 42 and - according to the pizhnem - photorelay 43.

Above the shafts, rollers 28 are located along the semifinished product, feeding the semi-finished product into and out of the shaft, and the pulling rollers rotate periodically to take a loop of material from the sensor 43 command to the beginning of the sample and the sensor 42 to the end of the sample.

Behind the acid machine 35 in the production line, a multi-shaft flax shaft is installed, a batch machine 44, which consists of twenty whole corrugated work shafts 45, arranged in three rows, roller 46 and the conveyor 47 underneath it. The middle row of working rollers jointly reciprocating movement, the effect of which on the semi-finished product is the subsequent roll. The movement of the semi-finished product in the car occurs reversivio with a maximum; forward movement over the course back. To communicate the reverse movement of the work rollers, the machine is equipped with a command annarate, such as a time relay, with an electric motor (not shown in the drawing) for the drive of the rollers and the discharge conveyor.

Behind the multi-shaft shaft with a flax machine 44, there is a device 48 for cutting and removing nonwoven material, which consists of a drive roller table 49, a table 50 and a self-propelled cutter 51 equipped with a circular knife 52. Turning on the cutter is a time relay configured to receive pieces of material and the required length.

Between the subsequent machines there are also compensators 53 and 54.

The proposed line works as follows.

From the mechanized laboratories, the fiber periodically enters the buicker 3 but the commands of the sensors 8 of the lower level are fully filled but the sensors 7 of the upper level. From the bins, the fiber is periodically supplied to the drawers of the self-weights 4 according to the commands of the gauges 9 filling the latter. The batt from each carding machine 1 by the combing machine 2 is laid out on the backup conveyor 13. On the cotton canvas laid from the first carding machine, the canvas is applied from the second carding machine, then from the third one, etc. The addition of wat that comes from all carding machines is made strictly according to the coitur, which is achieved by adjusting the span of the laying conveyors 10-12 bypass converter. Thus, a wadded semi-finished product folded from watts received from the entire group of carding machines leaves the exit end of the duplicating conveyor 13.

Next, the cotton semi-finished product enters the preliminary compaction on the non-continuous sealing machine 15, and from there through the compensator 40 the length of the semi-finished product is periodically fed to the tile masking machine, where it is finally compacted. Then the compacted prefabricated product through the compensator 41 periodically enters the acid machine 35, where it is soaked with a solution of sulfuric acid and pressed.

Then the semi-finished product enters the multi-shaft shaft machine 44, where its roll is made between three rows of work rolls 45 with reverse-return

stepping movement of them. In this case, compensators 53 and 54 are used simultaneously as accumulators of a semi-finished product periodically supplied and removed from them.

Then, through the compensator 54, the dumped material is periodically pulled onto a roller conveyor 48 for a certain length specified by a time relay, cut into pieces, which are folded into layers 55 and transferred to further processing.
