(1) U-shaped non-return flower double hopper, can feed cotton in both forward and reverse directions, by acceleration/separation plate, one or two species can be fed at the same time, and can be flexibly adjusted with the number of units for each species . 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). 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.
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. (2) A differential pressure switch is arranged on the pipeline on the input side of the cotton box of the first card, which is used to control the stop and start of the feeding mechanism of the front machine (the last card).
By manually setting the cooperation of the stepper potentiometer, the number of free cotton can be adapted to the number of carding machines. (3) The airflow escaping from the mesh plate in the upper cotton box is collected by the students. In the pressure-stabilizing control box of the exhaust system designed by the students at the opening of the upper cotton box, the swing valve at the side exit of the pressure-stabilizing box can be adjusted by the market to ensure the airflow. Under a constant variety of social pressures, it can be discharged evenly through the upper cotton boxes of the teacher, so as to ensure the required drop distribution rate of each upper cotton box, so that the falling amount of each upper cotton box with the cotton head is equal. (4) The fibers of the upper cotton box pass through a pair of feeding rollers and open in the middle: the device enters the lower cotton box, and two soil and lower photoelectric tubes control the stop and rotation of the cotton feeding rollers (A7/C type cotton box has upper , The height detection reel composed of 8 tight-row photocells controls the feeding roller (multi-stage speed regulation) to adjust the fiber filling height of the lower cotton box. As long as the filling height is constant, under the action of the fiber self-weight and the beater airflow The cotton capacity and density of the cotton box can be constant, so that the fiber layer conveyed by the conveyor system to the card can be uniform.
(2) The FBK533 cotton feeding box of Truetzschler Company (1) is a double-section cotton box without back-flowering, and the lower cotton box adopts the fan circulating type continuous blowing. (2) The cotton conveying air hang with the yuan-level speed regulation continuously absorbs other fibers from the last cotton cleaning machine, and can be distributed to the upper cotton box of FBK533 through the cotton conveying pipeline. The air escapes from the filter screen and passes through the vacuum pipe Lead to the dust filter system, and the fibers fall into the upper cotton box. (3) Pressure and sensors are installed on the input side pipeline of the first upper cotton box; the feeding roller of the last cotton cleaning machine is driven by a variable frequency control motor.
In normal production, by inputting the rated working pressure value of the cotton conveying pipeline and the motor as the basic required speed value, the controller can directly adjust the pressure value of the variable frequency motor directly according to the pipeline learning pressure value transmitted by the student's pressure and temperature sensor. The rotation speed makes the feeding roller change speed, and realizes the purpose of feeding the cotton continuously and evenly in the blowing and carding unit. Due to the pressure value in the cotton conveying pipeline and the development of the fibers in the upper cotton box, China's high economic fluctuations are small, and the fiber cell density in the upper cotton box is relatively constant. (4) The roller is driven by a variable speed motor to keep the cotton warm, and the cotton fiber is continuously supplied to the tank opening beater, and then dried into a hopper after opening, and the circulating air of the continuous fan under the beater flows through the fiber at a certain pressure, and maintain a certain density.
The hopper pressure signal is fed by the controller in the pressure sensor, so that the step-by-step feeding feeds the roller element, in fact, it is a self-leveling system. The conveying speed of the rollers is also controlled by the conveying speed of the card, to match the output card.
