A lottery ball machine
is a machine used to shake various prizes. It is suitable for courts,
government agencies, enterprises, parties, bars, shopping malls and other
promotions that need to show fairness and justice, or all activities that have
lottery or number selection links.
machine is divided into stirring lottery machine and air blowing lottery
process of the lottery machine is based on scientific principles, and the
design of this series of lottery machines is completed through repeated
experiments and demonstrations. The performance characteristics of the lottery
machine ensure the fairness of the lottery results. Technical level: With the
continuous improvement of technical level, from the original manual to the
fully automatic lottery. The lottery machine is divided into two forms of
lottery: one is stirring type; the other is blowing type. The lottery is played
in two different techniques and in different ways.
1. The original
manual type: mainly use the turntable type and the box type. The basic
principle of the turntable type is that the object rotates at the center of
2. Box type: As
long as the central axis of the cylinder is used to rotate, the prize balls
inside will be randomly chaotic to achieve a random and fair effect.
3. The principle
of the stirring lottery machine is simply to use the rotation of the stirring
shaft to make all the balls move randomly, open the ball outlet within a
certain period of time, and the ball that just passes through the ball outlet
is regarded as the lucky ball.
First of all,
the lottery ball machine is used to prepare for the lottery. The standard ball
diameter is 4 cm, the surface is non-porous, hollow, non-magnetic,
non-metallic, lightweight, the same material, the same level of unified product
There are three
cantilever scrapers in the stirring area, which are driven by the motor to
rotate clockwise and counterclockwise respectively and directly act on the
prize balls, so no matter the weight of the prize balls, they can be brought to
the same place under the direct action of the scrapers. After a certain height,
it starts to fall, and his falling process is close to the state of free fall.
Compared with a stirring area with a diameter of 60 cm that is the same as the
surrounding gravitational acceleration and filled with natural air, the drop
limit of the prize ball inside is only 60 cm, free fall within this range,
their falling rates are almost the same, no one can occupy a favorable time and
position during the falling process, all the balls have a chance to randomly
land on the plane at the bottom of the stirring zone.
In the process
of taking out each prize ball, the prize ball in the cylinder is continuously
thrown up again by the scraper, and the scraper rotates rapidly forward and
reverse for several seconds, so that each prize ball is stirred with a
difference of 60 cm from top to bottom. The up-throwing and falling in the
barrel are in a natural and random ideal state. The collision between them is a
state of concentric collision, and the chance of repulsion is also equal. On the
plane, there will not be a situation where a certain type of prize balls can be
placed in a particularly advantageous specific position waiting to be
preferentially played due to the quality deviation of the prize balls. In this
way, the fairness of the lottery drawing process is guaranteed, and the
randomness can be said to be double insurance. This form of lottery chance
fully embodies fairness, randomness, science and the uncontrollability of the
The principle of
the air blowing lottery machine is more complicated. Simply put, when the
lottery machine is started, the fan introduces the air into the pressurized
pump, and the pressurized pump blows the compressed air into the stirring
chamber (transparent container) through the air duct, and shakes it. The prize
balls are "stirred" under the action of air flow. The electronic
control module opens the ball valve according to the time setting, and blows
out the specified number of lottery balls in turn. After the lottery is over,
the power is automatically turned off.
the size, direction, and strength of the airflow involve complex physical
principles such as fluid mechanics, kinematics, and cyclotron force fields.
ball machine can customize the different size, different Exterior, also customize
