Model JWF1418A Automatic Doffing Roving Frame

< p > > a href= "http://www.91se91.com/news/index_c.asp" > JWF1418A type < /a > automatic doffing roving machine has used the doffing form which is automatically filled with yarn from the flyer on both sides of the flyer frame, and adopts the built in automatic doffing system. The automatic spinning of the roving frame is realized from the doffing, changing the pipe, generating the head and driving automatically.

The full tube roving is automatically conveyed to the JWF9562 coarse and fine conveying system through the empty and full tube exchange device of the machine, and the coarse and fine yarn is connected with the spinning frame.

< p > the remarkable feature of the machine is automation and intellectualization. Automation is mainly reflected in its built-in automatic doffing system, "empty full tube exchange device", < a href= "http://www.91se91.com/news/index_c.asp" > roving "/a" and full yarn, and the way to do the roving winding and shaping through the "bow tie" above the tube yarn shoulder, as well as the automatic monitoring system in the automatic spinning process.

< p > EJK 212 roving machine integrates multi unit pmission, field control bus and optical mechatronics technology.

The flyer and bobbin are directly driven by the motor group, and a group of spindles or bobbins are used as a group. The asynchronous motor is driven by synchronous belt respectively. The flyer and the bobbins of each group are connected by synchronous belt respectively to increase pmission efficiency, save energy and reduce consumption, reduce noise. The production efficiency of coarse yarn spinning is increased by more than 50% compared with the traditional roving frame, achieving high speed, high yield, high quality and flexibility.

< p > the equipment control system is equipped with a human-machine interface, which can provide functions including parameter setting, operation display, fault reason hints, class production statistics and so on. The spindle number of the whole machine is 156 spindles, which is the longest roving frame in China.

The flyers and bobbins are separately driven by motors, saving energy consumption by 10%.

The drafting and dragline lifting are directly driven by the motor, and the maximum mechanical speed can reach 1500 rpm.

< p > HY-Auto498 fully automatic doffing roving machine is designed with high speed, high efficiency and intelligence. The doffing process of the equipment is accurate and stable, and the seamless pmission of thickness and thickness can be realized.

The layout of the fuselage is reasonable, and the head pmission is stable, reliable and easy to operate. It is suitable for high-speed operation.

The four main pmission and draft systems of spinning adopt mature control technology and pmission mode, and the drafting four rows of rollers are 32mm in diameter.

< p > automatic doffing structure is made up of an external collective doffing structure and a two degree of freedom Xialong rib. The doffing time is not limited by the number of vehicle spindles, and the automatic doffing time is about 2 minutes.

Multi motor frequency conversion synchronous control, automatic doffing success rate, ATC replacement success rate and automatic birth success rate of nearly 100%.

< p > color touch screen is used as man-machine dialogue window. The production process parameters are convenient to input, the roving tension control and adjustment are convenient and simple, and the doffing parameters can be flexibly adjusted according to the needs of customers.

Seamless connection with the coarse and fine conveying system, the free pfer of full yarn and ATC between the roving frame and the spinning frame can be realized by hanging the pmission track, thus saving the workshop space and eliminating the quality defects such as yarn defects and Mao Yu caused by humans.
