Description

Technical Field

[0001] The utility model relates to the technical field of automatic doors, in particular to an automatic door device and an automatic coffee vending machine. Background Technique

[0002] With the improvement of people's living standards and the continuous improvement of the requirements for the quality of life, more and more people will buy some beverages to meet their own needs, and coffee is one of them.

[0003] Coffee refers to a beverage made from roasted and ground coffee beans. Together with cocoa and tea, it is one of the main beverages popular in the world. In order to meet the needs of a large number of white-collar workers in office buildings to drink coffee, coffee vending machines will be set up in office buildings. White-collar workers can quickly get a cup of coffee they want by paying. In general, coffee capsules in the coffee vending machine are brewed with water, and then the brewed coffee is pushed out of the coffee outlet to the outside of the coffee vending machine. An automatic door is installed at the coffee outlet.

[0004] Although the existing automatic doors can be opened and closed, they have a complex structure and do not have an anti-pinch function, which poses a potential risk of pinching the customer's body or items. Content of the Utility Model

[0005] To achieve the above object, the utility model provides the following technical solutions:

[0006] An automatic door device includes a control board, a fixed shaft, and a motor. The motor is fixed on the front cover, and a rear cover is installed at the rear end of the front cover. The front cover and the rear cover form a cavity for installing components. The number of fixed shafts is two, and a window door is installed between the two fixed shafts through a window door fixing plate. Grooves conforming to the shape of the window door are provided on both the front cover and the rear cover. The two fixed shafts are respectively installed on the left and right sides of the front cover. Sliders are installed at the four corners of the window door fixing plate, and the sliders are slidably installed on the fixed shafts. A guide rail is connected between the two sliders on the same fixed shaft, and both sides of the window door fixing plate are installed on the guide rail. An upper limit sensor and a lower limit sensor are respectively installed at the upper and lower ends of the front cover. Optocoupler sensors are installed at the upper ends of the two fixed shafts, and the optocoupler sensors on the two fixed shafts are at the same height. Each optocoupler sensor is fixedly connected to the slider. The output end of the motor is connected to the slider. The control board is electrically connected to the optocoupler sensors, the motor, the upper limit sensor, and the lower limit sensor. When starting to work, the control board sends instructions to the two optocoupler sensors, and the two optocoupler sensors emit laser light. When the two laser lights are successfully opposed, the optocoupler sensors send signals to the control board, and the control board sends instructions to the motor. The motor rotates forward and drives the slider to move downward. The slider drives the guide rail and the window door to move downward synchronously along the fixed shaft until the slider moves to the lower limit sensor. The lower limit sensor sends a signal to the control board, and the control board sends a signal to the motor, and the motor stops working. At this time, the automatic door device is in the open state, and the customer can take out the coffee. After the coffee is taken away, the control board sends instructions to the motor, and the motor rotates reversely and drives the slider to move upward. The slider drives the guide rail and the window door to move upward synchronously along the fixed shaft until the slider moves to the upper limit sensor. The upper limit sensor sends a signal to the control board, and the control board sends a signal to the motor, and the motor stops working. At this time, the automatic door device is in the closed state. At the same time when the window door starts to move upward along the fixed shaft, the control board sends instructions to the two optocoupler sensors, and the two optocoupler sensors emit laser light. When the two laser lights are successfully opposed, the motor is in the reverse rotation state. When the customer's body or other foreign objects are placed at the window door, the two laser lights being opposed are blocked, and the optocoupler sensors send signals to the control board. The control board sends instructions to the motor, and the motor rotates forward, thereby driving the window door to move downward. This function is to prevent the customer's body or items from being pinched or damaged. During the process of the window door moving downward, the two optocoupler sensors are always in the state of emitting laser light. Only when it is detected that the laser lights are successfully opposed again, the optocoupler sensors send signals to the control board, and the control board sends instructions to the motor, and the motor rotates reversely, thereby driving the window door to move upward. In this device, the optocoupler sensors, the sliders, the guide rail, and the window door form a whole, moving upward and downward simultaneously, and the motor does not move. The role of the fixed shaft is to provide a fixed direction and stroke for the upward and downward movement of the window door. When assembling this device, first fix the internal components on the front cover, then fix the front cover as a whole on the inner side of the coffee outlet, and finally install the rear cover.

[0007] As a further solution of the utility model: The motor is installed on the front cover through a motor fixing plate, with good connection stability, ensuring that the motor will not move and will not fall off the front cover.

[0008] As a further solution of the utility model: The surface of the motor is covered with a motor cover, which can protect the motor, thus ensuring that the motor can work continuously.

[0009] As a further solution of the utility model: The window door is made of acrylic material, with high brightness and smoothness, not easy to break, and convenient for processing.

[0010] As a further solution of the utility model: A window groove is provided on the window door fixing plate, and the window door is fixed in the window groove. The four corners of the window door fixing plate are all connected to the fixed shaft.

[0011] As a further solution of the utility model: A limiting piece is connected to the slider at the lowermost end of a fixed shaft, which can limit the movement of the slider, thereby ensuring that the slider will not fall off the fixed shaft and enabling the window door to always maintain its working state.

[0012] An automatic coffee vending machine includes the above-mentioned automatic door device.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The product is reasonably designed and has a simple structure. It uses the cooperation of components such as optocoupler sensors, sliders, and motors to realize the automatic up and down movement of the window door. By judging whether the laser of the optocoupler sensor is successfully emitted during the up movement of the window door, the change of the motor is determined, thus avoiding the customer's body or items being pinched by the up-moving window door, and having a good anti-pinch effect.
