Description

Slip mechanism of single spindle cotton suction pipe of compact spinning frame

Technical Field

The utility model relates to a slip mechanism of a single spindle cotton suction pipe of an integrated compact spinning frame, belonging to the technical field of spinning frames.

Background

The spinning machine drafts the roving sliver to the required number, then twists the roving sliver to make the roving sliver have certain strength, elasticity and luster, and finally winds the spun yarn into a cop. The drafting mechanism of spinning frame generally adopts several groups of roller mechanisms to draft, and a negative pressure pneumatic gathering device for fibre sliver aggregation is added in the lower portion of main drafting, and the lower portion of said pneumatic gathering device is equipped with a cotton-sucking flute tube, on the cotton-sucking flute tube several cotton-sucking ports are set, every cotton-sucking flute tube is communicated with negative pressure suction cabin by means of air channel, and can be used for sucking away the fibre spun from roller when it is damaged or the broken end of yarn spun from roller so as to reduce flying and improve the quality of spun yarn, at the same time can be winded on the driving roller for preventing broken end produced in spinning process. The existing ultra-high speed and ultra-long spindle number becomes the mainstream of the development of spinning equipment, but each cotton suction flute pipe corresponds to one negative pressure pneumatic gathering device, one negative pressure pneumatic gathering device corresponds to 8 spindles and other ultra-long spindle numbers, and the negative pressure loss of the cotton flute pipe far away from a fan is more serious, so that the cotton suction capacity is reduced and is unstable. In order to solve the problems, the prior cleaning device adopts a plurality of independent cotton suction pipes arranged on an air duct, so that the negative pressure in the cotton suction pipes is basically the same, and the cotton suction capacity can be improved.

At present to the installation of inhaling cotton pipe a inhale cotton pipe dead lever fixed structure, be about to inhale cotton pipe demountable installation on inhaling the cotton pipe seat, inhale the cotton pipe seat on inhaling cotton pipe dead lever, and inhale cotton pipe dead lever and then install at two dead lever supports, two dead lever supports are packed into the junction of roller stand and are fixed with holding screw, this kind of structure only adopts a screwed connection of tip, it is not hard up easily to appear in the driving in-process in later stage, cause dead lever support displacement, and lead to inhaling cotton pipe dead lever and appear the phenomenon that both ends are highly uneven, and then can lead to inhaling cotton pipe and enclose the wearing and tearing to the net, and improve use cost. Then, because of the cotton suction tube dead lever position is fixed knot structure, the cotton suction tube dead lever is the operating position during spinning only, and the position is interior partially, when wiping the car and changing the cotton suction tube of damage, operating space is little, can influence the work progress because of the inconvenient operation, especially when changing apron down, still need pull down each cotton suction tube, just has operating space, stretches into the below of round pin, back roller and special-shaped pipe down with the hand, changes apron down, and the operation is wasted time and energy. Therefore, the cotton suction pipe fixing mechanism has the problems of long installation and debugging time in the early stage and inconvenient operation of cleaning, maintaining and replacing leather rings in the later stage. The other structure is that the cotton suction pipe fixing rod is of a sliding structure, the cotton suction pipe is detachably mounted on a cotton suction pipe seat, the cotton suction pipe seat is mounted on a fixing rod support, two ends of the cotton suction pipe fixing rod are connected with plugs, the plugs are arranged in sliding grooves of the fixing support, the cotton suction pipe fixing rod is connected onto the fixing rod support, and the cotton suction pipe fixing rod is enabled to be in working positions and non-working positions at two ends of the sliding grooves, so that the problems of single-spindle suction nozzle replacement and inconvenience in cleaning are solved. However, the two ends of the fixing rod of the cotton suction pipe are connected through the plugs, the plugs of the fixing support are arranged in the sliding grooves, so that the installation accuracy of the plugs and the looseness appearing in the later driving process can cause the position change of the cotton suction pipe, and then the cotton suction effect is influenced. And moreover, due to the inconvenience in integral disassembly and assembly, when the lower leather collar is replaced, the cotton suction pipes still need to be disassembled, so that the operation is time-consuming and labor-consuming.
