Detailed Description

In order to make the technical solutions and advantages of the embodiments of the present application more apparent, the following further detailed description of the exemplary embodiments of the present application with reference to the accompanying drawings makes it clear that the described embodiments are only a part of the embodiments of the present application, and are not exhaustive of all embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

In the related art, when the distance between two rollers of a grinding machine is adjusted, an operator usually performs multiple times of debugging according to own experience and the type of a product to determine a proper target distance so as to ensure the production stability of the grinding machine after the machine testing. However, the roller spacing is often changed during operation of the grinding machine, and since the spacing between the rollers is often small, it is difficult for the operator's naked eye to detect the change in the roller spacing in a timely manner.

For example, the distance between the rollers may be gradually increased, and an operator cannot find the phenomenon that the distance between the rollers is increased in time, so that the problem of incomplete grinding is caused, and the quality of the soap is influenced; or the distance between the rollers may be gradually reduced, and the operator cannot find the reduction of the distance between the rollers in time, so that the speed of the grinder is restricted, the productivity is low, and the soap production efficiency is affected.

Moreover, since the operator usually carries out multiple times of adjustment according to own experience, the adjustment takes a long time, which is not favorable for the production efficiency of the soap and is difficult to ensure the processing racing speed. In addition, in the debugging process, an operator usually measures the distance between the rollers by a feeler gauge manually, and the accuracy of measurement is poor due to the problems of operation methods and the like, so that the method is time-consuming, is not favorable for the production efficiency of the soap, is difficult to ensure the processing precision and is not favorable for the quality of the soap.

In order to overcome at least one of the above problems, embodiments of the present application provide a method for controlling a roller spacing, a terminal device, a grinding machine, and a storage medium, where an actual spacing between rollers is obtained through the terminal device, an actual error of an actual spacing property with respect to a standard spacing is determined, and whether the actual error is within a preset error range is determined, so that the terminal device is favorable to find a situation that the actual error exceeds the preset error range in time, generate a grinding stopping instruction and send the grinding stopping instruction to the grinding machine, so that the grinding machine is in a grinding stopping state according to the grinding stopping instruction, and can adjust a gap between the rollers in time. So, too big or when the actual interval at the gyro wheel, terminal equipment can in time discover that the actual error surpasss predetermined error range to control to grind the machine and be in and stop grinding the state, adjust with the actual interval that can in time be to the gyro wheel, grind the machine and just can carry out the grinding operation at predetermined error range until the actual error of the actual interval of gyro wheel, thereby do benefit to the actual interval control that will grind the machine gyro wheel and at predetermined within range, do benefit to the quality of guaranteeing to wait to grind the product.
