The mechanism and function of the winding and forming part of the carding machine

(1) The iron gun of the carding machine The iron gun of the carding machine is responsible for the management and control of the speed of the bobbin winding system (variable speed and part) and the transmission of the upper dragon tendons in the carding machine. 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. Special equipment for the textile industry on the winder.

As the last process of spinning and the first process of weaving, winding is the link between the past and the next.“bridge”Therefore, it occupies an important position in the textile field. 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. At present, most of the enterprises adopt a hyperbolic iron cannon, which is composed of a pair of Chinese upper and lower iron cannons (see Figure 7-19). Cannon, when changing the position of the belt, you can change the transmission ratio of the company's upper and lower iron cannons to make the lower iron cannon change speed.

The theoretical requirements for the shape curve of the iron gun of the carding machine should meet the following conditions: (1) After each turn of the bobbin, the iron gun belt should move a certain distance to the small diameter end of the movable iron gun (the upper iron gun), and each time The distances moved should be equal. (2) The sum of the corresponding radii of the upper and lower iron guns should be equal to a constant, so that the iron gun belts must always be under relatively uniform tension control. (3) When the synthetic development speed obtained by the last wheel of the differential protection device of the swing device of the carding machine is transmitted to the bobbin, since the upper dragon tendons drive the bobbin to move up and down, we need to establish a special mechanism to Transmission bobbin, this research mechanism can be called swing device.

Figure 7-21 Swing device introduced by the universal joint is the new model and the most commonly used. It consists of spindle flower, sleeve spindle and spider two trunnions. On the right side of the gear shaft, the gear and its meshing line are eaten at a fixed position for rotation; on the left side gear train and reel shaft or with LONG elevator, etc.

Flowers in the main shaft sleeve are stretched with variable transmission distance to the main shaft to compensate for the lift generated by LONG; the universal self-adjusting crosshead shifts to adapt to the lift generated when the driving direction changes. In order to prevent students from generating additional speed, the following two important conditions must be met: (1) The input shaft, output sleeve, ingot auxiliary head and two universal cross heads must move on the same plane. (2) The input sleeve must be parallel to the output shaft, ie 1 = revenge.

For this reason, when the carding machine is installed, it is necessary to ensure that the a-axis and the b-axis are horizontally parallel in space, and to ensure that the two crosshead forks of the enterprise correspond to different positions.
