Description

TECHNICAL FIELD

[0001] The utility model relates to food cooking processing articles, especially a food making mechanism of food vending machine with temperature detection structure. BACKGROUND

[0002] There are many heating methods for cooking food containers, such as electric heating, microwave heating, gas heating and steam heating. When cooking food by steam heating, the food container and soup are placed in the container after being cooked, and then placed in the heating space (the heating space also serves as the output chamber). A steam inlet hole is provided on the wall of the heating space, and steam is input into the heating space through the steam inlet hole to heat the entire heating space to cook the food container. In order to meet the needs of selling instant food, the skilled person in the art tries to design a food making and selling machine that stores raw food containers and cooks raw food containers. During the process of food making, the temperature of the food needs to be detected. For steam heating, the temperature sensor is inserted into the meal box through the hole of the steam pipe to detect the temperature. For microwave ovens and other electrical appliances, the thermometer needs to be in contact with the surface of the meal box to detect the temperature accurately. Since the height of the meal box is different, the existing making unit cannot detect the temperature by contact. SUMMARY

[0003] The utility model aims at providing a food making mechanism of food vending machine with temperature detection structure, which can detect the temperature of meal boxes with different heights by the temperature sensor, and solves the problem that the existing food making and selling machine can only detect the temperature non-contact.

[0004] The above technical problems are solved by the following technical solution: a food preparation mechanism for a food vending machine with a temperature detection structure, comprising a heating unit, a temperature sensor for measuring the temperature of a lunchbox located on the heating unit, a robotic arm for transferring the lunchbox, and a driving mechanism for driving the robotic arm, characterized in that it includes an anti-detachment structure and a vertical sliding sleeve located above the portion of the heating unit supporting the lunchbox. The temperature sensor is vertically and flexibly inserted into the vertical sliding sleeve. The anti-detachment structure is used to prevent the temperature sensor from detaching from the vertical sliding sleeve. The temperature sensor is provided with a sensor lifting member, and the robotic arm is provided with a robotic arm lifting member. During the process of the driving mechanism driving the robotic arm to drive the lunchbox to the portion of the heating unit supporting the lunchbox, the robotic arm lifting member lifts the sensor lifting member to raise the temperature sensor and avoids interfering with the movement of the lunchbox. When the robotic arm is in the position of driving the lunchbox to the portion of the heating unit supporting the lunchbox, the robotic arm lifting member loses its lifting effect on the sensor lifting member, and the temperature sensor is supported on the lunchbox. When the height of the lunch box is different, the temperature sensor can be supported on the top wall of the lunch box to measure the temperature, and the temperature measurement is reliable.

[0005] Preferably, the lifting component of the robotic arm has a front lifting ramp and a rear lifting ramp distributed along the moving direction of the robotic arm. The highest points of the front lifting ramp and the rear lifting ramp are aligned together. The lifting component of the robotic arm cooperates with the top block through the front and rear lifting ramps. This ensures good stability when the temperature sensor is lifted and lowered, thus reducing the risk of damage to the temperature sensor or it puncturing the food container.

[0006] Preferably, the sensor unit lifting component is equipped with rollers that cooperate with the front and rear lifting ramps. This reduces wear.

[0007] Preferably, the lifting component of the robotic arm includes a front tilting rod and a rear tilting rod, with the high ends of the front tilting rod and the rear tilting rod connected together. The front lifting ramp is disposed on the upper surface of the front tilting rod, and the rear lifting ramp is disposed on the upper surface of the rear tilting rod. This provides a specific technical solution for a lifting component of the robotic arm, which has a simple and compact structure.

[0008] Preferably, the robotic arm includes a pusher and a connecting rod connecting the pusher to a drive mechanism. The pusher includes a push rod and a stop bar connected to the push rod, with the angle between the push rod and the direction of movement of the robotic arm being less than 90°. In use, the lunchbox is moved by pushing it with the push rod, and the stop bar prevents the lunchbox from shifting.

[0009] Preferably, the driving mechanism comprises a slide rail extending along the moving direction of the mechanical arm, a sliding seat connected to the slide rail, and a sliding seat translation mechanism for driving the slide rail to move on the sliding seat, and the mechanical arm is connected to the sliding seat.

[0010] Preferably, the sliding seat translation mechanism comprises a belt, a driving pulley arranged at one end of the slide rail, a driven pulley arranged at the other end of the slide rail, and a driving motor for driving the driving pulley to rotate, and one end of the belt is connected to the sliding seat, and the other end of the belt is sequentially wound around the driven pulley and the driving pulley and then connected to the sliding seat.

[0011] Preferably, the inner circumferential surface of the vertical sliding sleeve is provided with a sliding sleeve rotation-stopping plane extending vertically, and the surface of the temperature sensor is provided with a temperature sensor rotation-stopping plane matched with the sliding sleeve rotation-stopping plane. The rotation displacement of the temperature sensor can be avoided.

[0012] The utility model has the advantages that when the meal box arrives, the temperature sensor can synchronously avoid, so that the temperature sensor can always abut on the meal box to measure the temperature, and the reliability during temperature detection is good.
