Fiber shuffling machine

In recent years, due to the advent of low-loss optical fibers and the development of special optical fibers for detection, a new fiber-optic sensor engineering technology has emerged in the field of optical fiber applications following the optical fiber communication technology. Fiber optic sensors are available in both functional and transmission types. The reflective fiber sensor is a transmission type fiber sensor. Optical fibers are a medium that transmits light waves using the principle of complete internal reflection of light. It consists of a high refractive index core and cladding. The refractive index of the cladding is smaller than the refractive index of the core, and the diameter is approximately 0.1 mm to 0.2 mm. When light passes through the end face into the core, when it reaches the interface with the cladding, the light is reflected back to the core layer due to complete internal reflection of the light. This way, after constant reflection, light can travel forward along the core. Due to the influence of external factors (such as temperature, pressure, electric field, magnetic field, vibration, etc.) on the optical fiber, the optical wave characteristic parameters (such as amplitude, phase, polarization state, etc.) are changed. Therefore, as long as people measure the relationship between these parameters and external factors, they can detect changes in external factors through changes in optical characteristics. This is the basic working principle of fiber-optic sensors. The reflective fiber sensor is a transmission type fiber sensor. The fiber adopts a Y-shaped structure, and two ends of the two fibers are combined to form a fiber probe, and the other end is divided into two, which are respectively used as a light source fiber and a receiving fiber. Light is coupled from the light source to the light source fiber, transmitted through the fiber, directed to the reflective sheet, and then reflected to the receiving fiber, and finally received by the photoelectric converter. The light source received by the converter is related to the surface properties of the reflector and the distance from the reflector to the fiber probe. . When the position of the reflective surface is determined, the intensity of the received reflected light changes as the distance from the fiber optic probe to the reflector changes. Obviously, when the fiber optic probe is placed against the reflector, the receiver receives zero light. As the distance between the fiber optic probe and the reflecting surface increases, the received light intensity gradually increases, and after reaching the maximum point, it decreases as the distance between the two increases. Reflective fiber optic sensor is a non-contact measurement with small probe, fast response, linear measurement (within a small displacement range), and high-speed displacement detection in a small displacement range. From the structural principle of the fiber optic sensor, it can be seen that the reason why the fiber shuffling machine can respond to the information quickly and transmit information quickly is entirely due to the fiber sensor.

Poker shuffling machine

The automatic poker shuffling machine belongs to the technical field of entertainment equipment, and has a left and right card box, an intermediate card box and a control module. The upper and lower cards are arranged on the partition between the middle card box and the left and right card boxes. There is a tray in the middle card box. The card holder is mounted on the lifting mechanism. The bottom of the left and right cards is equipped with a friction plaque mechanism. The left and right card boxes are symmetrically arranged on both sides of the middle card box. The lower pass is located at the junction of the left and right cards and the partition. The bracket is equipped with a friction plaque mechanism, the bottom surface of the left and right cards, the upper surface of the tray and the side of the tray. With the sensor, the sensor on the side of the card holder corresponds to the three sensing points arranged in the vertical direction on the side of the middle card box. The utility model does not have the phenomenon of listing and card in the process of shuffling, and the operation is stable and reliable, and the number of times of continuous reshuffle can be set as needed.

Non-magnetic automatic shuffling machine

The non-magnetic automatic shuffling machine is a manufacturing field of a shuffling machine which is a building block-shaped playing card, comprising a table top, a shuffling device placed on the lower part of the table top and a conveying device placed around the lower part of the table top; the shuffling device comprises a tray a shuffling bucket placed thereon and a shuffling cap placed in the shuffling bucket with a card slot; the conveying device includes a card conveyor belt that is coupled with the card outlet port and a card transport conveyor placed under the three-dimensional connection The grooving device is provided with a flop at the intersection of the delivery tray and the delivery conveyor belt; the invention is rotated by the shuffling cap to drop the card into the card slot, and after being recognized by the identifier, the flop is turned over by the flopper. The card does not need to be originally loaded through the magnetic body of the card and the corresponding magnetic material system; the overall design of the invention is reasonable, compact, high degree of automation, convenient to install and use, and can meet the requirements of various building-like playing cards.

Fully automatic mahjong shuffling machine

The fully automatic mahjong machine originated in Japan. After the reform and opening up, it was introduced to China. It was first operated by some high-end hotels. Later, some merchants saw business opportunities, so they began to copy, and the first recognized mahjong machine imitation in China. The success was succeeded by Hangzhou Songgang Electromechanical, namely the Queyou brand. Later, there were Dafeng enterprises, and the Dalu and other enterprises followed up. Then they entered the era of the group and the drama. The card was also introduced to China’s 30# small The card was gradually successfully transformed into 42#, 44#, and even the big name of No. 46. And the mahjong machine may be a very special one among many home appliance machines. It was invented by Japan, but it did not enter the Chinese market.

The veneer on the back of the mahjong tile is magnetic, the front is not, the card is rotated with the disk on a sloping disk. When the card rises to the height, the card with the magnetic side is sucked by the iron ring above the disk. And as the ring rotates, it is sent to a slot and pushed away by the lever. The card without magnetic on the front continues to rotate on the disk. The cards on the slot are doubled and then distributed by the pusher to the four sides. There is a small spring on the disc to turn the card, so that the front card is turned down, and the magnetic ring is sucked up by the iron ring until all the cards are sent to the trough. After the number of cards on all sides is sufficient, the button is operated by a person, and the pallet below the card sends the cards stacked on the table.

Inside the mahjong table, there are five electric motors that drive the turntable and the chain (the push rod on the chain) to rotate and are automatically controlled by the electronic chip.
