Description
Technical Field
The invention belongs to the technical field of non-woven machinery, and particularly relates to a doffer cleaning device of a carding machine.
Background
The above-mentioned carding machine is an indispensable component of the entire production system of nonwoven products, because nonwoven products such as nonwoven fabrics, nonwoven felts and the like are subjected to opening by an opener, carding by a carding machine, lapping by a lapping machine and needling by a needle loom (or hydroentangling by a hydroentangling machine) in this order.
Technical information relating to carding machines is largely found in published chinese patent documents, such as CN202671748U (non-woven high speed scrambled output carding machine), CN202671744U (non-woven high speed scrambled carding machine), CN115648582a (non-woven fiber carding equipment), CN104312788a (high performance fiber carding machine for carding blended fabrics and carding method thereof), CN1313660C (flat card for multi-feeding fibers in the form of fiber mats) and CN2816061Y (full fixed flat card), to name a few.
During the working process of the carding machine, triangular areas are respectively arranged between a main carding roller serving as a main cylinder and an upper cotton outlet roller serving as an upper doffer and a lower cotton outlet roller serving as a lower doffer, specifically, an area between the main cylinder and the upper doffer is called an upper triangular area, and an area between the main cylinder and the lower doffer is called a lower triangular area. Because the existence of the triangle area which cannot be eliminated can generate cyclone effect (namely airflow vortex effect), the cyclone can affect the cotton outlet effect and the cotton outlet efficiency, and wind blocking rollers or wind blocking plates are generally adopted to solve the technical problem, such as CN200958134Y (carding device of carding machine) and CN206089904U (carding machine) are used for relieving the airflow by arranging the wind blocking rollers; also CN202466005U (non-woven fabric carding machine) is used to alleviate air flow by providing wind shields, i.e. to prevent cyclone phenomenon. In addition, the high-speed carding machine proposed by the applicant and recommended by the grant publication number CN106222812B can effectively eliminate airflow vortexes in the triangular area by using the upper triangular area airflow decomposition mechanism and the lower triangular area airflow decomposition mechanism, and has positive significance for reducing carding rings, reducing CV values and improving the lapping quality of subsequent processes.
However, since the surfaces of the upper and lower doffers are respectively wrapped with the card clothing, the card clothing on the surfaces of the upper and lower doffers are wrapped with the fiber flocks including short fibers, so that the cleaning is relatively easy for the upper doffer at regular or irregular intervals because the card clothing is positioned above the card clothing during the operation, but the cleaning is troublesome for the lower doffer because the card clothing is positioned below the carding machine, and the cleaning is required after the relevant parts are removed, so that the production efficiency is affected due to long downtime on one hand, and the working strength of the equipment maintainer is increased on the other hand. Further, if the next doffer cannot be cleaned well as required, the fibers transferred from the next doffer are difficult to satisfy the level required for the process, for example, the grammage of the product is affected by the reduction of the fibers, because the fiber flocks (including short fibers) are embedded in the clothing covering the surface of the next doffer. Yet another situation is: if the foreign dust which is originally entangled and embedded in the card clothing is brought out at a glance during the fiber transfer process, the subsequent processes such as the lapping effect of a lapping machine and finally the quality of the product are affected, and the product is even a defective product. Therefore, how to keep the next step in a good cleaning state basically all the time has long been a technical problem which is concerned by the industry and is expected to be solved, and the technical scheme which is described below is generated under the background.
