This type of device also has various, gathers but all can produce flyings at the suction slot afterbody that gathers pipe.Take several different methods to attempt to remove the influence of long-pending lace at present, as the disclosed device of Chinese invention patent application CN1367281A at a fiber of a spinning machine upper set, it is in order to reduce the danger that flyings gather at the suction slot afterbody, the suction slot terminal is widened, promptly strengthened the space of suction slot afterbody, preventing that as far as possible terminal at suction slot from producing this fiber and gathering, but actual contrast test shows that to remove the flyings effect not remarkable.

Simultaneously, discover that conveyer belt is that the tightness degree that contacts behind the jaw line reduces with gathering pipe after gathering the roller contact-making surface, easier at this sticking flower of removing belt inner surface.

Summary of the invention

Technical problem to be solved by this invention is to overcome the above-mentioned defective of prior art and a kind of pipe that gathers that ribbon uses that gathers is provided, suction slot terminal fiber accumulation phenomena is eliminated, at any time easily remove the sticking flower of ventilative belt inner surface, make the gap periods of cleaning work of compact spinning apparatus prolong the fibrous index optimization of resultant yarn.

The present invention solves the problems of the technologies described above the technical scheme that is adopted:

Gather the pipe that gathers that ribbon uses, several suction slots are arranged on its surface, and the other end that described suction slot contacts with roller is provided with a fixedly groove of connectedness, and described connectedness is fixed in the groove, described connectedness is provided with an air duct, and communicates with the suction slot afterbody.

Above-mentionedly particularly behind the jaw line of connectedness, air duct is set, can removes the flyings that accumulate in belt inner surface more up hill and dale like this gathering the air duct that setting communicates with the suction slot afterbody on the connectedness of pipe.

The width of the afterbody of the above-mentioned air duct that is provided with on connectedness cans be compared to the tail width of suction slot most and also wants big, so more helps forming preferable air-flow, improves the efficient of removing flyings.

Gas channel on the connectedness constitutes whole gas channel with the afterbody that gathers the suction slot of pipe, under the effect of gathering pipe internal negative pressure air-flow, has formed from atmosphere and has taken the gas channel end to and enter the air-flow of the inside of gathering pipe to suction slot again through ventilative the conveying.This air-flow is brought the sticking flower of ventilative belt inner surface and the flyings that may fall suction slot terminal below into and is gathered pipe inside and be transported to the outer special flyings gatherer of device via gathering pipe.

Also can carry out specialized designs to obtain better effect to the shape and size of gas channel, the extra negative-pressure air-flow that gas channel consumed simultaneously also seldom.

Compared with prior art, the invention has the advantages that: by gas channel is set in connectedness, suction slot terminal fiber accumulation phenomena is eliminated, can play simultaneously the sticking flower of removing ventilative belt inner surface at any time, make the gap periods of cleaning work of compact spinning apparatus prolong the fibrous index optimization of resultant yarn.Also since conveyer belt behind the jaw line with gather pipe contact not too tight, so easier gas channel that enters on the connectedness of the sticking flower of its inner surface, therefore easier except that spending.
