Italian company, darcy new flat wire processing equipment and the product characteristics are introduced

Release Time：2022/09/13

As is known to all, main combed cotton carding machine is between the cloth and the cylinder cover needle cloth. Both matter, is the key to realize high quality components. Textile experts at home and abroad, manufacturers, deepening the study of both in order to achieve its optimum spinning adaptability, higher is better. Our country the earliest introduction of flat wire production line is wuxi spinning apparatus in the 80 s, the introduction of the Swiss graff equipment technology; Followed by gansu silver also introduce some; Until 2000, and by shanxi Venus spinning apparatus company introduced Italy, darcy (scardassi) flat clothing production equipment and technology of the company.

Now will I company introduced Italy, darcy's new flat clothing production technology, equipment, products are mainly summarized specifications, using range and its characteristics of, for your reference.

1. The main process equipment:

1.1. Process there are three major features:

A. plant needle machine computer control, from the mechanization to the electromechanical transition;

B. all needle machine coated hone, break through the pattern of the past, with small, fine, fine development;

C. the H2 quenching, air cooling process, a new quenching process, to the use of different effects.

1.2 characteristics of the equipment:

Point device name the name of the company

Darcy by planting needle machine

Controlled by computer, can make the tip longitudinal not equidistant array. Programmable 100 models, output by the computer, modification and quick.

Ascending part of the computer control, the longitudinal error is small. Various technical parameter programming. There are 20 kinds of model, to choose from.

Grinding needle machine turnkey hone drum, a pair at a time, two grinding head, computer control, frequency control of motor speed.

Hardening machine H2 and compressed air quenching, compressed air cooling, polishing machine configuration

2. The new type of flat wire specifications

Type, serial number of the wire tip number column optimal spinning range

30/34 SXJT 46 460 full arc satin high count and high yield

42 28/32 420 fine yarn, in the fine in full arc satin synthetic fiber

30 27/31 300 full arc satin in the coarse yarn, synthetic fiber

In 28/32 SXST 45 450 satin fine yarn and high yield

36 28/32 360 fine yarn, chemical fiber in the satin

29 27/31 290 satin in the coarse yarn, cotton type chemical fiber

SXRT 40 28/32 400 horizontal fine yarn in the light

33 28/32 330 horizontal light coarse yarn, cotton type chemical fiber

3. The new plant needle arrangement improve carding quality

Conditions at home and from abroad, the classification of the new type of flat clothing has two big characteristics: one is the needle is arranged, can be divided into horizontal dense type, light type, dense, uniform dense gradually. 2 it is flat wire lateral tip the change of the distance, in order to improve carding effect. Cut-off for 0.5 mm, not more than 0.5 mm for the new flat clothing, conversely for ordinary flat clothing.

3.1 uniform dense type: transverse, longitudinal from needlepoint equally arranged, lateral tip from larger at the same time, such as

709 lateral tip distance of 0.94 mm; 715 is 1.06 mm; 702 is 1.06 mm; Also belong to the previous common flat clothing.

3.2 horizontal dense type: lateral tip distance not greater than 0.5 mm, is also a new type of flat clothing, such as SXST, MCC series, my company's SXST45, SXST36, SXST29 its lateral tip distance of 0.3528 mm and 0.3629 mm were smaller than the same type of graff. (0.4233 mm)

3.3 light type: thin area and area, from its lateral tip for 2, such as my company SXRT40, SXRT33, its lateral tip from 1.41 ~ 0.94 mm. In carding fiber from the loose zone, comb out the dense area, fiber is gradually opening.

3.4 gradually close type: vertical wire tip from the gradient or part of a gradient. At present can be divided into two kinds, one kind is the needle density of districts, dense area of needlepoint evenly arranged, dilute zone needlepoint for arc type. Such as SXPT52, 46, 37 and domestic JPT52, etc; From the first line is a kind of tip density change, arrange for the whole arc tip, such as the production of the company introduced Italy SXJT46, SXJT42, SXJT30, etc. The lateral tip from SXPT series of 0.3528, SXJT series is 0.3175 mm. Italian SXPT its dense region accounts for a third series, loose area accounts for two-thirds of; Graff JPT series dense area accounts for two-thirds, loose area accounted for a third.

New flat clothing from lateral tip encryption, longitudinal tip from dilute gradually, make the fiber from the loose zone, comb out the dense area, gradually increased the carding effect and avoid local carding, reduce fiber damage, to improve carding effect reducing neps, remove impurities, can be spun yarn count, can be applied to domestic and foreign various high-speed carding clothing and carding.

4. Improve the flat clothing wear-resisting degree, sharpness, flatness and roughness.

4.1 wear resistance

Using hydrogen and compressed air, air cooling quenching, special quenching process, greatly improve the hardness and the needle quenching evenness, through actual measurement, the hardness is as follows:

Depth of hardening quenching hardness of single error of steel wire

0.1 ~ 0.5 of 880 ~ 920 HV 60 HV or less 100% Belgium and domestic steel wire

0.6 ~ 1.0 of 850 ~ 900 HV 50 HV 96% or less

1.1 ~ 1.2 900 HV 40 HV 80% or less

1.5 ~ 2.0 426 hv

The original wire hardness is 593 hv

Note: foreign clothing needlepoint hardness is generally in the 850 hv (0.1 0.4).

4.2 sharpness

Side grinding fineness of 0.16 0.19 mm, side grinding depth in 2.7-3.0 mm, blade shape R 0.6 0.8 mm. The edge depth of 0.5 0.6 mm, through the rough side and side pressure grinding, fine grinding process control.

4.3 finish

In addition to the role of needle process increasing fine side grinding, improve surface finish, remove the burr on both sides, and after polishing treatment after quench the fire. In grinding needle, the steel wire is about 550 hv, toughness, hardness or brush light could not remove burrs in the grinding needle, only after quenching harden and removed by polishing.

4.4 the flatness

With one pair of turnkey hone mixing mill for grinding needle, and include other domestic import equipment, also is a big and a small two roller grinding needle hold tight. All close to the drum surface finish, flatness test after the grinding needle, the pay is 0.05 mm to 0.06 mm, single for 0.03-0.04 mm, demand for single flatness, no industry standard. But using unit is strict, on a frame to test single effect.

5. Use of raw materials

5.1 import process equipment production imported plate with material steel wire for Belgium, high wear-resisting level B "are: 30/34, 28/32, 28/32, for double convex wire, the steel wire ingredients:

C Mn Si P S

0.70 0.80 0.90 1.20 0.15 0.35 0.025 0.025 or less or less

5.2 steel strip for two kinds of imported Japan and Italy, a light, a galvanized,

5.3 backing by wuxi letter a domestic textile equipment factory production of five pairs of rubber and six layers of rubber cloth
