Description

Automatic mixing, opening and carding complete equipment for multi-component fibers

Technical Field

The utility model relates to a spinning machine technical field, concretely relates to multicomponent fibre automatic mixing opens carding complete sets.

Background

The existing mixing, opening and carding equipment is equipment adopted in necessary processes for processing fibers or wool into strips, the processes are mutually independent, and materials need to be transferred among the processes in the whole production flow. The processing procedures are primary opening, mixing, impurity removing, secondary opening and carding procedures in sequence, after the carding and the web forming, the stripping mechanism strips the doffer into strips, the strips are wound into a strip winding barrel by a strip winding device, the materials need to be manually transferred among stations, the labor intensity is high, time and labor are wasted, and the efficiency is low. When multi-component fibers are mixed, a plurality of wool feeders are needed to feed, primary opening devices are fed through conveying flat curtains to perform primary opening, the plurality of wool feeders feed materials simultaneously, the problem of uneven distribution easily occurs on the conveying flat curtains, the problem of uneven primary opening is caused, the impurity removal effect is poor, especially, metal impurities in materials are difficult to remove, and the damage to equipment is large.

Working rolls of the carding equipment are matched with a large cylinder to continuously comb fibers or wool yarns, the fibers or the wool yarns continuously fall onto rotating shafts at two ends of the working rolls in the carding process, and the fibers or the wool yarns are wound and gradually increased on the rotating shafts due to the fact that the rotating shafts are exposed and continuously rotate. When the number of fibers or wool wound on the rotating shaft is large, the normal operation of equipment can be influenced, certain potential safety hazards exist, the only method is to stop the machine to clean the fibers or wool on the rotating shaft, the manual cleaning has the problems of large cleaning difficulty, high labor intensity, trouble and labor waste and high cost, and particularly, the production efficiency can be seriously influenced by the regular stop of the machine for cleaning.

A doffer, a large cylinder and a working roller of the carding equipment are all installed on a rack through bearings, the doffer is not provided with an independent driving device, the cylinder drives the doffer to rotate through a belt drive and a gear mechanism, and after the working period, the machine needs to be stopped to clean the surfaces of the doffer and the cylinder respectively. Because there is the transmission relation between doffer and the cylinder, in order to improve cleaning efficiency and shorten the time of shutting down, doffer need independently rotate, and the electromagnetic clutch controls for the gear mechanism that drives doffer. Because the carding machine or the carding machine can produce more dust and short fibers in the process of carding fibers or wool, the dust and the short fibers are easy to enter the inside of the electromagnetic clutch to cause the failure of the electromagnetic clutch, the separation of a gear mechanism of a doffer can not be realized in the process of stopping and cleaning, and the electromagnetic clutch has the defects of poor use reliability, instability and low service life. Therefore, the prior art is in need of further improvement.
