Non-chain revolve flat of carding machine

Abstract

The invention discloses a chainless rotary cover plate for carding machines. The cover plate, comprises a rotary cover plate and working flexible rails that movably support the rotary cover plate; front drive wheels and rear drive wheels, to handle the rotary cover plate, are arranged respectively outside the front end and rear end of the working flexible rails; above the rear drive of the front drive wheel mount back guide rails; both front and rear ends of the back guide rails are respectively adjacent with the front drive wheels and the rear drive wheels; the front sides of the front drive wheels are also composed with front steering rails; the rear sides of the rear drive wheels are composed of rear steering rails. The working flexible rails are movably full of rotary cover plates that are arranged in parallel and press with each other; however, the back guide rails are movably scattered with rotary cover plates. The back guide rails appear in polygonal line shape. The chainless rotary cover plate for carding machines has advantages of stable running, no additional force or deformation, stable cover plate space and excellent carding performances.

Description

technical field [0001] The invention relates to a carding machine for carding textile fibers, in particular to the improvement of the structure of the cover plate mechanism of the carding machine. Background technique [0002] The carding machine flat mechanism is one of the core components of the carding machine for textile fiber carding. When working, the carding machine cover plate and the cylinder will further carefully comb the cotton bundles and loose fibers after the initial carding of the licker-in rollers, so that they can basically reach the state of single fibers, and remove some small impurities in the fibers. Textile processing creates basic conditions. [0003] The carding form of the carding machine has evolved from the initial fixed flat carding machine to the roller carding machine, and then developed to the rotary flat carding machine that is still commonly used today. This rotary flat plate is composed of flat bone and flat card clothing. The cross secti...

Problems solved by technology

[0004] Although the rotary flat carding machine has the advantages of fine carding and uniform mixing under certain conditions, it also has some serious shortcomings; The traction is carried out on the sliding surface of the curved track. On the one hand, the chain provides the traction force to the cover plate, and also exerts a normal pressure on the cover plate. This additional normal pressure increases the distance between the cover plate and the curved track. The friction resistance between the rails intensifies the wear between the heel and toe surface of the flat and the sliding surface of the curved rail, thereby reducing the stability of the flat gauge, which is extremely unfavorable for the carding machine to maintain good carding performance; on the other hand, Due to the difference in the arc of the sliding surface of the curved track and the height between the heel and toe surface of the cover plate and the sliding surface of the curved track, the additional normal force of the traction chain at both ends of the cover plate will cause the flexible bending and / or twisting deformation of the cover plate bone, Seriously affect the stability of the flat gauge, which seriously reduces the carding performance of the carding machine

Although the existing cover plates all use "T"-shaped cross-sections in an attempt to enhance the bending strength of the cover plates, this does not fundamentally change the deformation of the cover plates

Secondly, the actual utilization rate of the existing rotary flats is extremely low. The traditional rotary flat carding machine has a total of 106 flats, of which only 40 are working flats, even among the 85 flats of the high-production carding machine , there are only about 30 working cover plates, so the actual utilization rate of the cover plates is lower than 40%, and the other 60% of the cover plates are running empty.

In addition, the sliding structure of the heel and toe surfaces at both ends of the cover not only increases the friction resistance and wear, but also affects the service life of the cover bone
