Problems solved by technology

But it still has the following defects: because the air suction seam gradually approaches each other until the nip according to the moving direction of the conveyor belt, the fiber strips on the two air suction seams with opposite angles have at least one fiber strip with the direction of hairiness and compact spinning The twist direction of the strands is inconsistent, which causes the hairiness of the compact spun strands to increase and the strength to decrease, which affects the product quality of the compact spun strands
It has the following defects: since the air suction seam and the moving direction of the conveyor belt are parallel to each other until the jaws, the width of the air suction seam is much larger than the fiber strips, so that the fiber strips on the two air suction seams cannot be closely attached to the air suction seam On the side, the accumulation effect becomes worse, which also causes the hairiness of the compact spun strands to increase, and the strength is reduced, which affects the product quality of the compact spun strands

Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] A compact spun yarn spinning device mainly includes a drafting device, a gathering device and a twisting device arranged downstream of the drafting device.

[0021] Figure 1 shows part of the drafting device and the gathering device of the compact spun yarn spinning device. The gathering device is between the drafting device and the twisting device, and it mainly includes: a gathering with a suction channel 8 and an air suction slot 12 Tube 9, a gas-permeable conveyor belt 7 fitted on the collecting tube and transported by tensioning pulley 6 and collecting roller 1, and a friction-reducing reinforcing member 10 arranged in the conveying area on the collecting tube.

[0022] Fig. 1 also shows part of the mechanism of the drafting device: a pair of output drafting rollers 2, 5 and a pair of front apron pairs 3, 4, which transport the fib...

Abstract

The invention relates to a compactness strand spinning device that includes a drafting assembly, two fiber sticks, a gathering area, a conveyer belt, air intake sew and twister. Two paralleled air intake sews are not paralleled to the moving direction of conveyer belt. The advantages of the invention are low yarn faults, better bar, and stronger brute force. It could also be used to produce compactness strand spinning composite yarn and worsted spinning strand and chemical fiber. The application value of spinning fiber would be improved.

Description

technical field [0001] The present invention relates to a production device for strands, in particular to a spinning device for compact spun strands, which comprises a drafting device, whose front roller pair outputs two stretched fiber strips, and there is a gathering area downstream of it , There is a breathable conveyor belt in the accumulation area, conveying two fiber strips through the adjacently arranged suction slots, and twisting the fiber strips together in the twisting device set downstream of the accumulation area. Background technique [0002] Existing strand spinning device mainly contains following two classes: [0003] A kind of device for producing strands disclosed in Chinese patent document CN1453405A, the device is equipped with a drafting device, and its downstream has a gathering zone and a twisting device that twists two stretched and gathered fiber strips together. device, an air-permeable conveyor belt transports the stretched and gathering fiber st...
