Intelligent controller for steamed bun cutter

Abstract

Disclosed is an intelligent controller for a steamed bun cutter. A counter and an electromagnetic clutch controller conventionally controlled by a cutting motor are controlled by a stepping motor instead. Rolling motor control and pressing motor control are integrated. All-digital speed regulation is adopted. Therefore, cost is lowered, energy consumption is lowered, noise is reduced, and weight is reduced. Double closed-loop control of a pressing motor and a rolling motor is implemented, so that steamed buns are equal in shape and size. A photoelectric ranging sensor is installed below a cutter, so that counting the number of the steamed buns is achieved and management mechanism is added on the basis of operations of the rolling motor, the cutting motor and the photoelectric ranging sensor. Records can be inquired conveniently with an added calender clock. The intelligent controller has the functions of power failure detection, zero-cross detection, continuous operation between power failure and power up, delay startup of initial operation and the like. In addition, all operating modules are weak current buttons, so that safety is increased. The whole intelligent controller integrates software and hardware and is controlled highly intelligently. Animation on color screen enhances man-machine interface effect.

Description

technical field [0001] The invention relates to a control device, in particular to an intelligent controller for a knife-cut steamed bun machine. Background technique [0002] The working principle of the existing conventional steamed bun machine in the market is as follows: First, the flour is mixed with suitable water, and the regular dough cake is processed by the steamed bun machine or an additional dough mixer, and the dough cake is put into the pressing surface, and then the dough is put into the pressing place, The noodle-pressing motor controls the noodle-pressing mechanical device to make dough cakes of appropriate thickness, which are transported to the rolling place through the conveyor belt; the noodle-rolling mechanical device driven by the rolling motor rolls the noodle cake into a cylinder; driven by the conveyor belt to the cutting surface Running, the movement of the noodle-cutting mechanism is controlled by the counter at regular intervals. When the time is...

AI Technical Summary

Problems solved by technology

[0006] There are three insurmountable shortcomings in the knife-cut steamed bun control system of the modified counter: 1) During the counting value period when setting the counter, the output form of the counter is the same as the output form of the counting end, which makes the cutter work all the time and wastes energy; 2. ) In the event of a power failure, and the proximity switch is close to the low level position of the turntable output or offset from the correct position, an inaccurate count value will be generated for cutting steamed buns. Low level position, so that the proximity switch always outputs low level. When the power is turned on again, the external signal keeps resetting the counter, and the counter cannot work. At this time, the power needs to be cut off. Turn the turntable half a circle to the position and then power on.

[0012] In order to raise the product to a higher level, some manufacturers use a larger touch screen to set the timing parameters in the counting control part. This product has a good visual effect, but it has not been integrated, the function is not strong, and the degree of intelligence is not good. Not high, no application prospects, high cost

[0013] The main disadvantage of the steamed bun machine control system described above is that it is limited to the transformation and design of the knife-cut steamed bun control

Retrofitting with conventional counters has many disadvantages, and the cost has no advantage

Although the self-developed controller has added some functions, it has not really realized intelligent control, so it can only be developed and used by itself, and it has not been well promoted.
