[0051] Each of the above embodiments can be implemented individually, or any two or more can be combined.

[0052] The above embodiments will be described in more detail below in conjunction with specific examples.

[0053] Example 1:

[0054] In order to realize the rapid and accurate loading operation of vegetables and the like, the present embodiment provides a vegetable ingredient weighing device, as shown in Figures 1 to 3 and the like, comprising:

[0055] a support frame 1;

[0056] a lower belt conveying mechanism 2 mounted on the support frame 1, which has forward and reverse conveying capabilities and adjustable conveying speed, and can move back and forth along the conveying direction on the support frame 1;

[0057] An upper belt conveying mechanism 3 is arranged above the lower belt conveying mechanism 2, and the conveying speed of the upper belt conveying mechanism 3 is adjustable.

[0058] A roller scale platform 4 is arranged beside the support frame 1 and used for placing the ingredient container 5, and the roller scale platform 4 has a weighing capacity and can receive the vegetables from the upper belt conveying mechanism 3 and the lower belt conveying mechanism 2 when the ingredient container 5 is placed on the roller scale platform 4.

[0059] The upper belt conveying mechanism 3 comprises an upper conveying belt 31 and an upper belt driving motor 32 for driving the upper conveying belt 31 to run through a transmission assembly, and the running speed of the upper belt driving motor 32 is adjustable. It should be noted that the belt conveying process of the upper belt conveying mechanism 3 is a conventional technology in the art, and the specific transmission assembly for realizing the belt conveying is not limited, and a conventional structure can be adopted, for example, a belt conveyor used in the food industry, which will not be described here. Similarly, the lower belt conveying mechanism 2 is the same.

[0060] The upper belt driving motor 32 can be a common conventional motor, which can be adjusted in speed through a frequency converter, thereby having multi-stage speed regulation function, for example, at least having high-speed and medium-speed two-stage speed regulation capacity. During the ingredient operation, the conveying speed of the upper belt driving motor 32 is adjusted to be high speed or medium speed according to the progress. It should be noted that "high speed" and "medium speed" are not used to limit the specific value of the conveying speed, but only to distinguish the conveying speed of the two, and the actual conveying speed can be adjusted adaptively according to the specific situation.

[0061] The lower belt conveying mechanism 2 comprises a lower conveying frame 23, a lower conveying belt 21 and a lower belt driving motor 22 arranged on the lower conveying frame 23, the lower belt driving motor 22 has forward rotation and reverse rotation capacity, the bottom of the lower conveying frame 23 is provided with a sliding roller 24, and the support frame 1 is further provided with a displacement control cylinder 25 connected with the lower conveying frame 23 and used for driving the lower conveying frame 23 to move back and forth along the conveying direction.

[0062] The moving stroke range of the lower belt conveying mechanism 2 satisfies that when the lower belt conveying mechanism 2 moves to the maximum outside the support frame 1, the lower belt conveying mechanism 2 can receive the vegetables sent from the upper belt conveying mechanism 3;

[0063] When the lower belt conveying mechanism 2 is retracted to the maximum inside the support frame 1, the lower belt conveying mechanism 2 completely leaves the path for the upper belt conveying mechanism 3 to feed the ingredient container 5, thereby not affecting the discharging process of the upper belt conveying mechanism 3 at the corresponding time.

[0064] In addition, the lower belt driving motor 22 also has multi-stage speed regulation function. Similarly, a conventional general motor can be adopted, and the speed regulation function can be realized by a device such as a frequency converter. For example, three stages of high speed, medium speed and low speed can be set. As described above for the upper belt driving motor 32, "high, medium and low" are not specific values for limiting the conveying speed, but are only used to distinguish the conveying speeds of the three stages. The actual conveying speed can be adjusted adaptively according to specific conditions.

[0065] The end of the support frame 1 located directly above the rolling track scale table 4 is further provided with two side baffles (divided into a left side baffle 12 and a right side baffle 14) located on both sides and a front baffle 13 located in front. The two side baffles and the front baffle 13 together form a "wide at the top and narrow at the bottom" discharging guide channel 11 for guiding the discharging direction of the vegetable material sent from the upper belt conveying mechanism 3. In addition, the front baffle 13 is detachably arranged on the two side baffles in a pull-out type. The front baffle 13 mainly prevents the vegetable material sent at high speed from splashing out.

[0067] The bottom of the rolling track scale table 4 is provided with a weighing sensor 41. The weighing sensor 41 can record the loading quality of the ingredient container 5 placed on the rolling track scale table 4 in real time. In addition, the upper part of the rolling track scale table 4 is a row of conveying rollers for moving the ingredient container 5. The weighing sensor 41 at the bottom can record the loading quality of the ingredient container 5 after moving onto the rolling track scale table 4 in real time.

[0068] According to the needs of automation modification, the device of the utility model can further include a controller for coordinating the operation of each component. The controller can coordinate the discharging process of the upper belt conveying mechanism 3 and the lower belt conveying mechanism 2.

[0069] The working process of the weighing device of the embodiment is as follows (taking the loading quality of the ingredient container 5 as 5kg as an example):

[0070] The ingredient container 5 is first sent to the rolling track scale table 4 through other conveying tracks. At this time, the ingredient container 5 is positioned at the discharging station (i.e. the loading station) under the guidance of the horizontal guide baffles 42. The display quality of the standard ingredient container 5 without vegetable material on the rolling track scale table 4 is set as 0 in advance.

[0071] First, the upper belt conveying mechanism 3 starts and feeds at high speed, the lower belt conveying mechanism 2 starts synchronously and also runs forward at high speed to send the stored vegetables of the last loading residue, when the loading quality reaches about 3kg, the high-speed loading process ends, at this time, the conveying speed of the upper belt conveying mechanism 3 is adjusted to medium speed, at the same time, the lower belt conveying mechanism 2 extends and runs reversely for a set time (at this time, the conveying speed can be set to medium speed), after receiving a part of the vegetables conveyed by the upper belt conveying mechanism 3, the lower belt driving motor 22 stops and drives the lower belt conveying mechanism 2 to retreat into the support frame 1 under the action of the displacement control cylinder 25.

[0072] Subsequently, under the medium-speed loading of the upper belt conveying mechanism 3, until the loading quality reaches about 4.5kg, the upper belt conveying mechanism 3 stops working, then the lower belt conveying mechanism 2 runs forward and maintains a low-speed state for accurate slow loading of the ingredient container 5. Since the conveying speed of the lower belt conveying mechanism 2 is low at this time, it only needs to stop slightly in advance when the conveying weight reaches the critical value of 5kg, so that the loading quality of 5kg can be accurately achieved, and the loading fluctuation range is reduced. Finally, the loaded ingredient container 5 is moved out of the discharging station under the action of the conveying rollers on the upper part of the roller scale platform 4, and the loading work of the next ingredient container 5 is carried out.

[0073] The existing belt feeding device, such as pure high-speed or medium-speed feeding, has the problem of unstable continuous discharging amount due to inertia when the belt conveying stops, which easily leads to a large fluctuation range of the vegetable quality entering the ingredient container 5. The device of the embodiment divides the loading process into multiple stages and cooperates with high-speed, medium-speed and low-speed belt conveying modes to accurately control the loading quality and also consider the loading efficiency.

[0074] The above description of the embodiments is for the convenience of those skilled in the art to understand and use the utility model. Those skilled in the art can easily make various modifications to these embodiments, and apply the general principles described herein to other embodiments without creative labor. Therefore, the utility model is not limited to the above embodiments, and those skilled in the art can make improvements and modifications within the scope of the utility model without departing from the scope of the utility model.
