Digital cotton-carding tester

Abstract

The invention discloses a digital cotton-carding tester, which comprises a cotton-delivering mechanism, an opening and cleaning mechanism, a combing and mixing mechanism, a cotton-stripping and winding mechanism, and a digital control system taking a touch screen as an operation interface, and is characterized in that: the cotton-delivering mechanism, the opening and cleaning mechanism, the combing and mixing mechanism and the cotton-stripping and winding mechanism are driven by adopting a synchronous belt; and a cotton-delivering motor, a licker-in motor, a cylinder motor and a doffer motor are independent variable frequency motors, and are respectively driven and controlled by a cotton-delivering frequency converter, a licker-in frequency converter, a cylinder frequency converter and a doffer frequency converter in the digital control system through the touch screen. The digital cotton-carding tester can meet the requirement on rapid test of various cotton-carding small samples.

Description

technical field [0001] The invention relates to a textile machine, in particular to a digital carding testing machine for carding raw cotton in the carding process. Background technique [0002] Carding is an important process in the spinning process. The traditional carding machine is driven by a main motor. In order to realize the transmission of fibers, opening and removing impurities, carding and mixing, and the transmission of the stripping and winding mechanism, the mechanical transmission structure of the carding machine is very complicated. The main motor is driven by a belt. The cylinder and the cylinder are driven by multiple flat belts and gears to the cotton rollers, licker-in rollers, doffers, cotton stripping devices, etc. The transmission is complicated and inefficient, especially in order to meet the requirements of the speed Group and worm gear to achieve deceleration, sudden change, unstable. The transmission mode of the existing carding machine has many ...

The traditional carding machine is driven by a main motor. In order to realize the transmission of fibers, opening and removing impurities, carding and mixing, and the transmission of the stripping and winding mechanism, the mechanical transmission structure of the carding machine is very complicated. The main motor is driven by a belt. The cylinder and the cylinder are driven by multiple flat belts and gears to the cotton rollers, licker-in rollers, doffers, cotton stripping devices, etc. The transmission is complicated and inefficient, especially in order to meet the requirements of the speed Group and worm gear to achieve deceleration, sudden change, unstable

The transmission mode of the existing carding machine has many shortcomings, especially it is not suitable for the rapid test of small samples of carding, mainly in the following points: (1) The long transmission adopts a flat belt, and the flat belt slips unavoidably, which affects the transmission efficiency and test accuracy ; (2) The short transmission gear has many transmission stages, the cumulative backlash error is large, and the transmission accuracy and transmission efficiency are low; (3) When the process speed needs to be adjusted, some parts, such as gears, need to be replaced first, which is troublesome to operate and inconvenient to test. Difficult to be fast; (4) Maintenance and repair workload is heavy, time-consuming and labor-intensive
