(1) Structure and working principle of MY-96 sawtooth gin
The structure diagram of MY-96 sawtooth gin is shown in Figure 8-14, and the working principle is as follows:
The cotton enters the workshop through the conveying system, and then After separation, cleaning, storage and distribution, the cotton is sent to the cotton storage box of the gin. The variable frequency speed drive drives the cotton feeding roller through the cycloidal pinwheel reducer to feed the cotton. According to the working pressure and density feedback current, the frequency conversion speed regulation is used to automatically control the amount of cotton feeding. The sub-cotton is first cleaned by the cleaning nail roller, and is thrown on the U-shaped rake roller in a fluffy state. It is blocked by the steel wire row. After being evenly pulled by the U-shaped thorn bars, after removing impurities and stiffness, it is evenly brushed on the cotton dripping board by the cotton brushing roller. Before feeding into the gin, when the cotton passes through spikes and U-shaped licker-in rollers, the discharged effective single particles of cotton are recovered by the U-shaped thorn bar recovery roller, and are fed to the cotton dripping plate by the cotton brushing roller. The remaining impurities, infertile children, dead pigtails and dust will be discharged from the machine through the impurity discharge auger.
The cotton fed into the front box of the gin is sent to the gin saw blade through the licker-in roller. The teeth of the saw blade pull the cotton into the working box through the barrier ribs. At this time, the running speed of the cotton in the working box is equal to the linear speed of the saw blade. When passing through the rib working point, the saw blade will pull away the fiber embedded in the saw teeth, and the rest will continue to run with the cotton roll. At this time, the sub-cotton stays in the working box for about 1 minute. Due to the repeated pulling effect of the saw blade, the pulled sub-cotton continues to enter the working box. A gap formed by the speed difference is generated at this position and is rolled clean. The cotton seeds are continuously squeezed out of the working box from here, and discharged along the middle of the embossing rib and the barrier rib.
The fibers pulled by the saw teeth are brushed into the lint passage through the back box with a brush that is several times faster than the linear speed of the saw blade, and are sent to the lint cleaning machine. After cleaning, they are sent to the lint collection cage for packaging.
The MY-96 gin machine has made major improvements to the breast plate and the holding plate of the gin machine, and installed a row tube in the working box.
The row tube is located at the appropriate position in the working box, so that the hair clumps in the cotton roll area under working conditions become loose, and the hair smoothly breaks away from the constraints of the cotton roll and falls down quickly; at the same time, the row tube removes the hair clumps A considerable part of the wool in the cotton roll is rolled into the tube and discharged by the auger, which increases the amount of cotton rolls and greatly reduces the number of photons; in addition, the row tube drives the cotton rolls to rotate, which greatly reduces the stalling of the cotton rolls. phenomenon, which greatly improves the rolling range of the cotton gin.
(2) Main technical characteristics of the MY-96 sawtooth gin
The main technical characteristics of the MY-96 sawtooth gin are shown in Table 8-5.
(3) MY-96 sawtooth gin Electrical control system
(1) In order to adapt to the large-scale development of the cotton processing industry, many equipments currently adopt the advanced OPENPLC programmable control system, which will start, output, alarm, manual, etc. in the circuit Some parts are edited into corresponding programs, and the original button console is replaced by a touch screen, which truly realizes human-machine dialogue, implements automatic startup, automatic shutdown, fault alarm, and mutual interlocking, effectively protecting the motor and making operation convenient. ,Monitoring is intuitive.
(2) The control of the flower feeding motor uses a high-reliability frequency converter for intelligent control, which can achieve various protections for the ginning process.
(3) An electric push rod is used to open and close the working box of the gin machine, making the operation more convenient and the execution structure simpler and more reliable. The electric push rod is equipped with an overload protection device to protect the machine parts at any time during use. or other devices.
(4) For safety and ease of use, the entire ginning workshop is centrally controlled by the master console. The main console is equipped with buttons, switches, indicator lights and ammeters with various functions.
