Description

Technical Field

[0001] The utility model relates to the technical field of cooking machines, in particular to a weighing device for cooking machines. Background Art

[0002] In the actual application of the cooking machine, in order to count the consumption of ingredients and realize the intelligent process adaptation of the machine, a weighing device is installed, and the power is also output through the weighing device to realize the rotational positioning of the feeding. In traditional weighing devices, a multi-sensor cascade method is often used, with a weighing plate placed on it, and the measured weight is placed on the weighing plate to realize static weighing, such as a human scale, an electronic balance, etc. Another method uses a hub structure, which has a middle hole structure, which can realize the weight weighing of the heavy object hanging down or pressing up. The above weighing methods are all static measurement methods, that is, the measured object is placed statically. In the actual application of the cooking machine, the weight of the measured ingredients not only needs to be measured, but also the ingredients need to be positioned and placed, and the feeding box containing the ingredients needs to be rotated. To realize dynamic measurement, its structural form needs to be redesigned.

[0003] The multi-sensor cascade method is adopted, which has a complex structure and an integrated structure with an output shaft hole. It is large in size and the installation size cannot meet the requirements. The hub-type weighing sensor is used. Although the structure is simple and the size can meet the requirements, it is limited by the sensor itself, the accuracy requirements cannot be met, and the four-corner calibration cannot be achieved. The measurement of eccentric weights will produce a large error. The above structural method cannot meet the actual measurement requirements. If all the components of the weighing mechanism are placed independently on the load-bearing end of the sensor, some slight vibrations will be generated along with the operation of the cooking machine. The uninterrupted weighing of the sensor can easily cause damage to the weighing sensor. Utility Model Content

Compared with the weighing device of the cooking machine in the prior art, the present application can realize dynamic measurement while avoiding the problem that some slight vibrations cause the sensor to weigh continuously, which easily causes damage to the weighing sensor.

[0035] Intermediate fixing plate 100;

[0036] The rotating shaft 101 is arranged on the middle fixed plate 100;

[0039] A power output component is provided between the intermediate fixing plate 100 and the rotating shaft 101, and is used to provide a driving force for the rotating shaft 101 to rotate;

[0040] A lifting component is provided between the bottom fixing plate 102 and the middle fixing plate 100, and is used to lift the position of the middle fixing plate 100 so that a preset gap is generated between the middle fixing plate 100 and the weighing sensor 103;

[0041] By setting a bottom fixing plate 102, the weighing sensor 103 is fixed on the bottom fixing plate 102 through a connecting mechanism, and then an intermediate fixing plate 100 is set on the weighing sensor 103, and a power output component is set on the intermediate fixing plate 100 to provide a driving force for rotation to the rotating shaft 101. The intermediate fixing plate 100 is used to form the above mechanism into a whole, and power output is realized. When the intermediate fixing plate 100 is connected to the weighing end of the weighing sensor 103, all the components constituting the weighing mechanism are independently placed on the weighing end of the weighing sensor 103. When used, the weighing sensor 103 can adopt a parallel beam structure sensor, which has high measurement accuracy, simple structure, and four-corner pressure deviation compensation capabilities, thereby improving the accuracy of weighing. The power output component is placed on the intermediate fixing plate 100, and the weighing sensor 103 can weigh the intermediate fixing plate 100, and provide a rotating force to the rotating shaft 101. The output of force is used to drive the external feeding device and also realize dynamic measurement. After the rotating shaft 101 rotates and passes through the feeding device to feed the food, the lifting component can be used to lift the position of the middle fixed plate 100 upward, so that a preset distance is generated between the middle fixed plate 100 and the weighing sensor 103, that is, the middle fixed plate 100 is not in contact with the weighing sensor 103 at present, and the weighing sensor 103 is no longer weighed without affecting the power output component to provide the rotating shaft 101 with a rotational driving force, thereby avoiding the slight vibration caused by the motor rotating the rotating shaft 101 and the vibration generated when the cooking machine is working being transmitted to the sensing end of the weighing sensor 103, thereby reducing the pressure burden and work burden of the weighing sensor 103. Compared with the weighing device of the cooking machine in the prior art, the present application can realize dynamic measurement while avoiding the problem that some slight vibrations cause the sensor to weigh continuously, which easily causes damage to the weighing sensor 103.

When the horizontal plane height of the first support block 300 or the horizontal plane height of the second support block 302 remains unchanged, the connecting rod 301 gradually tends to be vertical, and one of the support blocks can be moved longitudinally to make the bottom fixing plate 102 or the middle fixing plate 100 move longitudinally, so that a preset gap can be generated between the middle fixing plate 100 and the weighing sensor 103, that is, the middle fixing plate 100 no longer contacts the weighing sensor 103, thereby achieving the purpose of reducing the working intensity of the weighing sensor 103.

[0052] As a further feature of the present invention, the connection mechanism includes a bolt 400 connected to the bottom fixing plate 102, and the bolt 400 is threadedly connected to the weighing sensor 103;

[0056] By setting the first axis 403 and the second axis 404, when one of the middle fixed plate 100 or the bottom fixed plate 102 is displaced, the first axis 403 or the second axis 404 moves accordingly. After ensuring that the middle fixed plate 100 or the bottom fixed plate 102 moves, the brushless motor 202 can also provide a rotational driving force for the rotating shaft 101.
