Roller is one of the carding machine, the main components.
Taking opening, removing impurity, transfer of fiber.
Its role to play good or bad, directly affect the cylinder and flat area of the carding and the quality of the cotton net.
But for various reasons, many units only attaches great importance to the cylinder, doffer and flat clothing SanPeiTao.
With less concern for roller rack, generally used for a long time, and in the process of licker in lapped, due to the structure of roller and the influence of lapped quality had to take the weight of grinding to ensure smoothness and roundness.
Such serious impact roller tooth sharpness, short service life, in addition to the noise effect is poor, after more than belly noil phenomenon.
If you want to ensure the sharpness, can only light grinding.
Cannot ensure that separation, separation process on sizes and affect the quality of article transfer and raw.
The current series of A186 carding machine roller eccentricity is relatively common, is also cotton carding process on one of the main problems.
Most manufacturers are using (
113608 k)
Bearing, even in the roller itself roundness good circumstances, set (
113608 k)
Bearing, eccentric obvious increase, and the position of the eccentric changed with the change of the position of bearing.
Under some special unit is used to pull the bearing pack again after grinding roller, problem is obvious.
Feeling after grinding needle cloth smoothness is better, but the car with the bearing, eccentric is created, and some bigger.
So experienced Lao shifu, is known around the bearing and the original location for installation, to reduce eccentric, it brought a lot of trouble to carding process on and influence.
The key element of affecting roller eccentricity according to the above situation analysis are as follows: (
1)
113608 k is ball bearing and taper sleeve opening, loaded on the thorn roll shaft concentricity is not too accurate.
(
2)
Taper sleeve and the shaft with push-pull cause deformation and tighten prison for many times, in the process of high-speed operation, loose caused by wear and tear.
(
3)
Sting roll shaft head partial bending is due to the eccentric.
Processing after using 3608 or 223608 bearing, collar diameter, is based on tire cylindrical roller iron as a benchmark, to fix the top pinhole after processing, small eccentricity.
General eccentric shaft and shaft sleeve, repair processing, can achieve good effect.
Now series of A186 carding machine are improved after this kind of structure, so the eccentricity is small, get the user's consistent approval.
In order to improve the licker in roundness, solve the problem of the eccentricity of the roller, prolong the service life of roller rack, making the following modifications for your reference.
Method is as follows: the original (
113608 k)
Bearing off, switch to 3608 or 223608 without taper sleeve bearing.
Check the roller eccentricity and wear, the necessary calibration and repair, two shaft sleeve on a lathe processing, as shown in figure 1.
According to the roller outer end face and bearing the actual location of the (
Actual location of the bearing in the car)
Do a card board position, as shown in figure 2.
After processed collar oil heating, respectively according to the position of the roller bearing the original set of spindle head, in front of the bushings, must place card board on the shaft, to determine the correctness of the roller bearing location, convenience of taker-in installed, as shown in figure 3.
Figure 1 collar figure 2 positioning card board for collar after cooling, the roller on the lathe processing.
Processing, with iron roller tyres as a benchmark, the cylindrical revised pinhole, ensure the licker in tire iron surface and pinhole concentricity and then respectively according to the revised top pinhole processing on the roller shaft sleeve, the shaft sleeve's outside diameter size bearings inside diameter size (
Tight fit)
。
Position in the same way, the card boards on the shaft, to avoid in the set of bearing collar position move inward, the bearing oil respectively after heating.
