          leather measuring machine

          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.
