The function of the weft insertion mechanism of the quilt is to introduce the weft yarn into the shed so that it can be interwoven with the warp yarn to form a fabric. The structure of the double twisting unit of the double twisting machine mainly includes the spindle braking device, the spindle part of the double twisting machine, the yarn winding device, and the special device of the double twisting unit. 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). 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. The oldest, and still in use, weft insertion mechanism is the shuttle mechanism, which utilizes the shuttle's reciprocating motion to introduce the weft into the shuttle. The shuttle mechanism of the quilt production line makes the shuttle rotate 40-50 degrees around the main shaft.
For a short period of time, enough speed to cross the shuttle (about 8-15 meters per second). The dynamic load at the start of the space shuttle is one of the reasons for the damage of the parts of the space shuttle mechanism. The space shuttle also has a lot of speed after flying out of the space shuttle.
It is a pity that most of the remaining energy of the space shuttle is converted into useless heat, vibration, noise, and disappears into the air through friction and impact between the space shuttle and the parts of the space shuttle mechanism, skin knots and space shuttle plums and leather rings . At the same time, due to impact and friction, it will also cause damage to the machine material and failure of the rear mechanism. Due to the above-mentioned shortcomings, the shuttle machine constitutes the main obstacle to the construction of the loom.
At present, the quilt production line has replaced the shuttle picking mechanism, including pit picking, jet (water) picking, projectile picking and multi-section shuttle picking! Weft mechanism. The common features of these new finding l mechanisms are: (1) the old shuttle is large and heavy, because the small female crab weft l“Engaging a rapier head, a gripper, or even the complete elimination of a mechanical weft insertion device, with air or water to deliver the weft yarn so reduces weft yarn abolition and power mechanism glucosidase negative Yinshen device, increases speed and reduces power consumption of weft yarn Aroma generation machine leather material.
