1.Strictly control the rolling process
conditions, choose the appropriate temperature, speed, pressure and contact
area of the hot roller according to the type, diameter and thickness of the
tube, and adjust the distance between the front and rear rollers at any time.
2. The adhesive tape should maintain a
large and even tension during the rolling process. As the thickness of the
adhesive tape is uneven or there are sampling holes, the adhesive tape of the
same model can be properly inserted.
3. The backing cloth must be flat when it
is inserted, and remove the rewind when there is a discount.
4. The end of the adhesive tape must also
be flat when it is inserted. When it is wrinkled or stuck to the rear roller or
the upper roller, it must be stopped, and the wrinkled part must be removed and
then re-rolled.
5. The temperature of the hot roller should
be measured at any time before and during the coiling process, and should not
be coiled if the temperature does not meet the process regulations.
6. During the rolling process, cooling
water should be passed through the rear roller and the upper roller, and they
should be cleaned with alcohol frequently to prevent the adhesive tape from
wrinkling and foaming.
7. When rolling, the aging, discounting,
curling, joints and sleeve dirt in the tape cloth bundle should be cut off with
a knife. The tape cloth should not stay on the hot roller for too long when the
upper pressure roller is raised.
8. After the rubber cloth tube is rolled
into a blank, it should be rolled for 3~5min to ensure the quality of the
product.
9. When a thick layer of rubber is formed
on the heat roller, it must be stopped and scraped off to prevent the rubber
from being caught in the product. Generally, the rubber cloth tube and glass
cloth tube should be shoveled once every 3 rolls. Otherwise, the rubber skin is
too thick, which will affect the temperature of the hot roller, and the resin
will not melt at low temperature, which will affect the performance.
10. When the tape is slightly skewed, the
end of the laminated tube may be unevenly rolled, you can adjust the tension
roller, generally you can also use a knife to cut one side of the tape to
adjust.
11. In order to clean the rubber skin
conveniently, the surface of the hot roller should be coated with a release
agent; for easy removal of the tube, apply a release agent on the surface of
the tube core.
