Description

one

The invention relates to the textile industry, in particular, to devices for obtsuvu airflow of pressure and the like machines and the simultaneous removal of dust, fluff and sweep from the aisles between the machines.

The weight of the cleaning device. From the down of the spinning machine, containing a duct installed under the machine and connected to the fan and a conveyor inside it, on one branch of which. Blow nozzles are installed, one of which is designed as an asymmetrical diffuser and fiMeeT its turning around, its.

This device allows you to simultaneously blow the floor and reins of the machine, which are located below and inaccessible for blowing by the sleeves of the collector installed above the machine.

However, the use of this device is effective only in conjunction with a collection box that needs to be installed above the machine, which complicates the design as a whole.

The closest to the invention of the technical essence and the achieved result is a device for cleaning the down of the spinning machine, containing an air duct mounted along the machine with two longitudinal channels connected to the fan for supplying and discharging air

10 suction and blowing hoses installed on the duct with the possibility of reciprocating movement along it and connected with it by means of nozzles, and filters dispensed in the suction sleeves 2.

Such a device, due to the presence of channels on the air and a vacuum, can be used for blowing fluff and dust with

2Q machines and at the same time collecting them.

Claims (2)

Onaco, this device does not automatically clean the filters, which complicates its maintenance. The aim of the invention is to simplify maintenance by performing automatic filter cleaning. The goal is achieved by the fact that, in devices for cleaning from the down of the spinning machine, containing, mounted along the machine, a woofer with color connected to the fan, longitudinal channels for supplying and discharging air, suction and blowing hoses installed on the duct with the possibility of reciprocating movement along it and associated with it through nozzles. and filters placed in the suction hoses, the duct additionally contains at least one air supply duct placed on one of the ends of the duct and connected to the fan, with the end part of the duct for diverting the air a made l-shaped and located between the duct at the end of the duct and the scoop part of the longitudinal duct for air supply, and the nozzles of the sleeves are offset one from the other along the length of the duct such that the distance between the centers of the pipes is not less than the sum of the radii of the latter. In FIG. 1 shows a device, a general scheme, side view; in fig. 2 - the same, top view; in FIG-3-Raaz A-A in FIG. one; in fig. 4- section BB in FIG. one . The device contains a duct 2 installed above the machine being cleaned on a bracket 1, inside of which one is installed; - drive 3 and tension 4 bar bans of tr & sprinter, covered by belt 5. Air duct 2 is divided by partition 6 into two longitudinal channels 7 and 8 connected by nozzles 9 and 1O to fan 11 connected to electric motor 12. Channel 7 is intended for air supply, and an 8-channel exhaust duct, Air duct 2 has at least one additional channel 13 for air supply, connected by a branch pipe 14 to a fan 11 and an air duct located at one of the ends. Kondeva part 15 of channel 8 is made -shaped and placed between cava om 13 and the end part 16 of channel 7. On duct 2, they are installed with the possibility of returning, with a stupid, movement along it suction 117 and blowing 18 sleeves connected to the air duct by branch pipes 19 and 2O fixed on the belt 5. Branch pipes 19 and 2 O are offset 4.4 each other . along the length of the duct so that the distance B between their centers is not less than the sum of radii 1 to the nozzles. In the suction hoses near the pipe 19, two filters 21 of bucket-type bump to the pipe are installed. The pipe 19 communicates with the air exhaust duct 8, and the pipe 2 O with the air supply duct 7. The drive drum 3 via a belt drive 22 and gearbox 23 is connected to the electric motor 12, and the duct has guides 24 arranged along its length. When the electric motor 12 is turned on, a fan 11 is turned on, which delivers air flow through pipes 9 and 14 to channels 7 and 13 by creating overpressure in them. At the same time, a vacuum is created in channel 8. The air mixture is sucked through the nozzles 25 on the sleeves 17, passes through the suction 17 sleeves, filters 21, pipe 19, channel 8 and goes to the fan. The impurities that are sucked in with the air are deposited on the filters 21. The air flow blown by the fan into the channel 7 passes through the nozzle 2O, blowing 18 sleeves, nozzles 26 on them and blows off the dust and down from the machine to be cleaned. From motor 12, rotation is transmitted through gear 23 and temporary gear 22 to drive 3 drum. When the drum 3 rotates, the conveyor belt 5 and together with it the blowing 18 and 17 suction hoses with nozzles 25 and 26 move along the air duct 2, blowing and collecting dust and fluff along the entire length of the machine. When the nozzles 25 and 26 reach the end of the duct, a limit switch (not shown) is triggered, as a result of which the tape stops and reverses. When moving the conveyor belt 5 in the opposite direction; suction 17 and blowing e18 sleeves cross channels 8 and 13 and change their mode of operation. Thus, the nozzle 19 of the suction 17 hoses is located above the duct 13, in which an excessive air pressure is created by the fan. The air flow, the exit from the channel 13 passes through the pipe 19 and the filters 21, cleans them and throws out the collected dust, fluff and sweep in the bunker (not shown). At the same time, the nozzle 2O of the blowing 18 sleeves is above the channel 8, and the air flow from the nozzle 2O and channel 8 goes to the fan, ensuring the operation of the system. The tightness of the duct is achieved by the fact that the air flow coming out of the fan presses the belt 5 to the guide 24. the breeder and thus prevents air from escaping. This device provides automatic cleaning of filters and eliminates uncomfortable working conditions associated with manual or semi-automatic cleaning. DETAILED DESCRIPTION OF THE INVENTION A device for cleaning the spinning machine's fuzz, a secondary air duct mounted along the machine with two longitudinal channels connected to the fan for supplying and discharging air, suction and blowing hoses installed on the air duct with the possibility of reciprocating movement along it with n through nozzles, and filters placed in suction hoses, characterized in that, for the purpose of maintenance, by performing automatic cleaning c, the air duct additionally contains at least one air supply duct placed at one of the ends of the duct and connected to the fan at the same time, the joint part of the duct for duct removal is L-shaped and located between the duct at the end of the duct and the end part of the longitudinal the air supply channel, and the branch pipes of the sleeves are displaced one relative to the other along the length of the duct so that the distance between the centers of the branch pipes is not less than the sum of the radii of the latter.
