Description

Roller shaft assembly for cotton carding equipment

Technical Field

The utility model relates to a weaving equipment field especially relates to a roller shaft subassembly for comb and parallel cotton fibers prior to spinning equipment.

Background

The working principle of the carding machine is that cotton (fiber) rolls sent from the previous process or oil cotton (chemical fiber) layers supplied by a cotton box are subjected to opening, carding and impurity removal, all curled blocky cotton rings are made into single fiber shapes which are basically straightened, broken seeds, impurities and short fibers left in the cotton cleaning process are removed in the process, and then cotton slivers with certain specifications are integrated and stored in a cotton cylinder for the drawing process.

The cotton carding equipment mainly comprises three roller parts: an upper roller, a lower roller and a stripping roller; because the bearing sleeve and the roller are assembled to form a gap, cotton or chemical fiber can easily enter the roller shaft through the gap during production, the roller shaft and the bearing sleeve are wound to be dead, and the bearing is burnt out; meanwhile, the running load of the motor is increased, and the motor is possibly overloaded and burnt out finally; in order to prevent the roller shaft from being wound, equipment maintenance personnel are required to clean the wound cotton or chemical fiber between the roller shaft and the bearing sleeve by using a hook knife every day; cleaning frequency: 3 times per day and 20 min per time; when the bearing is burnt out and replaced, the equipment needs to be disassembled and assembled for 2 hours/time. Therefore, the middle-upper roller bearing edge is easy to stop due to winding; meanwhile, the shutdown of the middle and middle upper roller bearing in use can cause the cleaning frequency to be improved, the production efficiency is reduced, and the spinning quality can be influenced. Roller bearing on carding machine comprises bearing rod and axle sleeve, its characterized in that: the sealing ring is arranged at the joint of the bearing rod and the shaft sleeve, one end of the sealing ring is clamped between the bearing rod and the shaft sleeve, the sealing ring is in a step shape, and the thickness of the sealing ring positioned outside is larger than that of the sealing ring positioned between the bearing rod and the shaft sleeve.

Aiming at the situation, a split structure that a nylon shell is sleeved on a pressing sleeve of an upper roller bearing shell in a spinning machine is produced in the market at present, the split structure can play a limited effect temporarily, but the phenomenon that a nylon jacket is shifted or even drops easily occurs during use, the service life of an upper middle roller bearing is greatly reduced, and meanwhile, as the nylon jacket is sleeved on the upper roller bearing shell in a pressing manner, when the outer diameter size and form and position tolerance of the nylon jacket are machined, the nylon jacket slides easily, the accuracy of the nylon jacket is difficult to guarantee, and therefore the spinning quality is influenced.

The patent application document with the name of a carding machine top roller bearing and the patent document publication number of CN203683763U discloses the following technical scheme: the sealing ring between the bearing rod and the shaft sleeve is provided with a convex part which is clamped in a groove of the bearing rod, and the sealing ring cannot rotate out along with the rotation of the bearing rod. The cross section of the sealing ring positioned outside is in a right trapezoid shape, the bevel edge faces outwards, the thrust force for pushing out the sealing ring is increased, and the probability of turning out the sealing ring is reduced. Although this use novel echelonment's that sets up sealing washer has reduced the clearance between axle sleeve and bearing rod to a certain extent, but like the bottle plug and stopped up the clearance mouth, although reduced the emergence of fibre card at the phenomenon of winding bearing rod, this kind of design is unfavorable for rotating on the roller axle, influences the function realization of roller axle, and inconvenient dismantlement is unfavorable for overhauing and maintaining moreover, consequently needs to carry out further improvement to it.
