Abstract

The utility model relates to a negative pressure air suction system of ring spinning frame among textile machinery, ring spinning frame need a negative pressure air suction system at the spinning in-process, and when spinning broken end, can inhale the cotton mouth of inhaling with the tow that the draft part was told, avoid winding the roller, also avoid breaking adjacent yarn. This negative pressure air suction system generally sets up a negative pressure storehouse of induced drafting at the rear of a vehicle, set up a negative pressure fan in the negative pressure storehouse of induced drafting, set up the filter screen before negative pressure fan, the tuber pipe is connected with bellows, arranges to the direction of disconnected length of spinning, has the cotton suction pipe with the roller correspondence position, and cotton suction pipe front end has the inlet scoop, and when the spinning is broken end, the tow gets into through the inlet scoop and inhales the cotton pipe then gets into bellows through the tuber pipe. When the ring spinning frame equipment is gradually lengthened, the negative pressure difference at the far and near fan ends is gradually increased, and the energy loss is increased.

Description

Negative pressure air suction system of ring spinning frame

Technical Field

The utility model relates to a machine-building trade, concretely relates to ring-spinning frame negative pressure air suction system among the textile machinery.

Background

In textile machinery, a ring spinning frame is spinning equipment from roving to spun yarn, the ring spinning frame needs a negative pressure air suction system in the spinning process, and the ring spinning frame is mainly used for sucking a fiber bundle discharged by a drafting part into a broken end cotton suction port in time when a broken end is spun, so that a roller is prevented from being wound, and adjacent yarns are prevented from being broken. This negative pressure air suction system generally sets up a negative pressure storehouse of induced drafting at the rear of a vehicle, set up a negative pressure fan in the negative pressure storehouse of induced drafting, set up the filter screen before negative pressure fan, prevent the fibre to get into the fan, the tuber pipe that is connected with bellows links to each other one by one and links to each other along the disconnected length of spinning to arrange, it has the cotton suction pipe to correspond the position design with the roller, the cotton suction pipe passes through the connecting pipe with the tuber pipe and links to each other, some cotton suction pipes are one for every spindle, some cotton suction flute pipes of one of six spindles or one of eight spindles, it has the inlet scoop to correspond every spindle roller position design on the cotton suction pipe, when taking place the spinning broken end, the tow gets into the cotton suction pipe through the inlet scoop and then goes into the tuber pipe, and then gets into bellows. The negative pressure requirement on the cotton suction pipe mouth cannot be too large or too small, when the negative pressure requirement is too large, the yarn is easy to suck and break, and when the negative pressure requirement is too small, the broken end cannot be sucked into the air suction port to cause the fiber bundle to wind the roller or form a large broken end, so that the smaller the negative pressure difference of the whole machine is, the better the negative pressure difference is. When the spinning frame equipment is gradually lengthened from 516 spindles to 2016 spindles, textile machinery manufacturers also take a series of measures to increase the power of a fan; enlarging the section of the cotton suction duct; the cotton suction air pipe is designed with variable diameters, the section of the air pipe close to the head is small, and the section of the air pipe close to the tail of the vehicle is large; the cotton suction pipe joint is reduced in diameter, the cotton suction pipe joints with different calibers are adopted in sections, the use requirement is really met when the equipment is lower than a 1200 ingot, but when the equipment is lengthened to a 1600-fold 2016 ingot, the negative pressure difference requirement of the whole machine cannot be well controlled by using the scheme or the schemes at the same time.

Disclosure of Invention

The utility model discloses a solve prior art and have the great problem of head and the tail negative pressure difference, with the big problem of burden machine power consumption.

The utility model adopts the technical proposal that: two negative pressure air boxes are respectively arranged at the head and tail of a spinning frame, fans are respectively arranged in the air boxes, filter screens are respectively arranged at the front ends of the fans, air pipes connected with the air boxes are connected section by section and are arranged along the length direction of a spinning section, cotton suction pipes are designed at positions corresponding to rollers and are connected with the air pipes, and cotton suction ports are formed at positions of the cotton suction pipes corresponding to the output positions of the rollers.

The middle of the air pipe is communicated.

The middle of the air pipe is disconnected.

The cotton suction pipe is a cotton suction pipe with six spindles.

The cotton suction pipe can be eight spindles with one cotton suction pipe.

The cotton suction pipe can be one cotton suction pipe for each spindle.

The air pipe joint is a reducing joint.

The reducer union has various specifications.

The specifications of the reducing joint are phi 25, phi 20, phi 18, phi 16 and phi 13.

The invention has the beneficial effects that: the air suction at two sides is more than that at one side, the air suction pipe of the ring spinning frame has uniform negative pressure, and the total power of the fans at two sides is less than that of the air suction at one side under the condition that the negative pressure at the air suction inlet is the same.
