Leather measuring machine, measuring machine, measuring machine is a
kind of equipment that needs to be purchased as raw materials for shoe
factories, leather goods factories, luggage factories, handbag
factories, furniture factories, car seat factories, leather factories,
etc. Leather machine, measuring machine for these factories plays a
vital role in leather cost accounting, open source throttling and
optimal utilization of leather As the saying goes, buying a leather machine is equivalent to a BMW car. Since the leather machine is so important, do you know the working principle?
Measuring leather area is a two-dimensional plane measurement problem.
Due to the irregular shape of the leather, the system uses the grid
accumulation method in the measurement, that is, the leather is divided
into small cells of equal area (in this system, each small area is
4cm2), and a unit of leather is synthesized. The number of leather can
be obtained. Use a motor-controlled conveyor belt to pass the
leather through the incandescent tubes and phototransistors located
above and below the two columns. The number of photocells is blocked by
the leather. Since the adjacent phototransistors are separated by 2 cm,
the area of the cells corresponding to each of the blocked photocells
is 4 cm2. Therefore, when a piece of leather passes completely, the
leather is blocked. The total number of photocells is multiplied by the
corresponding coefficient of the system to determine the actual area of
the sheet of leather. However, the edge portion of the leather
generally cannot completely fill the entire cell. The part that may be
covered during the measurement covers the illumination. It is considered
to be the area of a cell, and some parts are not covered by the
illumination. Going, this caused a certain measurement error. In theory,
further subdivision of the cell can improve the measurement accuracy,
but in fact, due to the sensor installation space and the operation
speed of the microcontroller, the subdivision of the cell is limited.
However, due to the fact that the accuracy of the corresponding area is
not very high during the leather industry transaction process, the
system as a commodity is able to meet all user needs and standards.
