The structural design and transformation of the production line drafting and twisting pipe for the quilt

Author:Xinjinlong Machinery-Fabric Recycling Machine Manufacturer

Improvement of the structure of the quilt production line pulling and twisting cylinder (1) The quilt production line system drive base and tube flag are made into one piece. The drive base and core material of the ordinary strip extension twisting tube are made into two pieces, and the two materials are different. Grinder A spinning machine that turns fiber strands into rovings. The main function is to draft and twist, and to wind the roving into a certain package to meet the processing requirements of the spinning frame.

Carding machines are used to process cotton fibers and chemical fibers and belong to textile machinery. According to the spinning process, carding is an important process. The front process of the carding machine is the opening and cleaning machine, and the latter process is the drawing frame (carding process) or the sliver coiler (combing process).

During the spinning process of the spinning frame, the semi-finished roving or sliver is drafted, twisted, and wound into a spinning machine. The combed sliver and the needle-carding machine combine the sliver, the needle row is drafted to improve the sliver structure, and the roving is further spun into spun yarn on the ring spinning frame, which is the main spinning machine. They are attached to the drilling agent. This method is common, but when the high method is running, it is easy to create relative slip between the transfer bottom and the die, making it unusable.

To overcome this shortcoming, the transmission base and the core can be made in one piece, made of wire mesh, as shown in Figure 4-43. The processing technology of the drafting and twisting tube of this quilt production line is as follows: the sea brocade plate or thin copper plate is punched into the silver metal sheet and pressed into the cup-shaped gold cylinder. . This is because the gear extension seat tube and the residence twist belt are integrally formed into a mold, these two do not exist, but the sliding between the two also reduces the retraction component Li Ying twist tube manufacturing steps, simple handling, reduce labor intensity, reduce Products into surgery.

In addition, because of the processing method used, the surface hardness is high, and the mechanical strength is also increased accordingly. (2) The center of the quilt production line and the bottom-loaded mold-like metal ring quilt gravity line drawing torsion tube is basically exhausted in the middle of the longitudinal direction, and it is not stable enough with large amplitude at high speed. Reference tubes are typically stretched requiring twisting at speeds of 8,000-12,000 rpm, with head dampened vibrations within 0.3 mm.

Twisted tubes are normally drafted to meet this requirement, which has been compared to reluctance, and produced with manmade fibers, with the development of Niagara drawing machine speeds, which have a tendency to advance to 20,000 rpm, thereby causing the twisted tubes to become incompatible. At the same time, the cylindrical plastic sleeve is easy to stretch and deform during use, especially recently, in order to increase the capacity of the package, the stretch and deformation are more serious. If the mold metal is broken on the bottom bag of the tube, expand both the core and the bottom of the casing into a cone, and you can solve our two main problems at the same time.

Die metal rings are two forms of steel, as shown in Figure 4-44. The length of the plastic sleeve must exceed the long skin of the four parts of the tube core, so that the lower part of the sleeve is also affected by the metal ring of the mold, forming a prototype, which is elongated and deformed when winding high-strength filaments such as nylon. After the steel is installed in the court, the impact center position of the drafting strand is moved down, improving the angry quality at high speed.

In the second form of Figure 4-44, the center of gravity is lower and the effect is more pronounced.
