Description

Technical Field

[0001] This utility model relates to the field of weighing equipment technology, specifically to a quantitative weighing device for fruits and vegetables. Background Technology

[0002] As people's living standards improve, they are transitioning from simply focusing on basic needs to prioritizing health. When purchasing fruits and vegetables, people are increasingly demanding higher standards in terms of both variety and quantity. In the process of automated production and packaging of fruits and vegetables, it is necessary to weigh them quantitatively to meet customer needs.

[0003] Chinese Patent No. CN216846486U discloses a quantitative weighing device for fruits and vegetables. The device first places the fruits and vegetables on a conveyor belt, which then moves them along the belt. When the fruits and vegetables reach a guide plate, they move along the guide plate. When they move out of the guide plate, they move onto a weighing plate. When the pressure sensor reaches the required weight, it sends a signal to the controller. The controller then controls the first hydraulic rod to descend and simultaneously controls the rotator to open. Rotating the rotator causes a baffle to block the fruits and vegetables on the conveyor belt. As the first hydraulic rod descends, the weighing plate tilts to form a ramp with the collection plate, causing the fruits and vegetables to fall onto the cushioning cotton. At this point, the controller controls the second hydraulic rod to push the push plate, causing the vegetables to fall into the collection box. Simultaneously, the controller controls the first hydraulic rod to rise, and the rotator operates to open the baffle, allowing for a second weighing. This device achieves automatic weighing and collection, greatly improving the operator's efficiency in weighing fruits and vegetables.

[0030] Reference Figures 1-4 A quantitative weighing device for fruits and vegetables includes a conveyor frame 1, on which a speed matching section 2, a weighing section 3, and a rejection section 4 are sequentially arranged. The rejection section 4 includes a rejection component 401 and a feeding component 402. The feeding component 402 includes a feeding rack 40201, a rotating frame 40202, and a drive component 40203. The feeding rack 40201 is inclined on one side of the conveyor frame 1, and feeding slides 402 are respectively arranged on its opposite sides. 0101, a rotating frame 40202 is rotatably provided between adjacent feeding chutes 4020101. The rejection component 401 is provided on the conveyor frame 1 and can push fruits and vegetables into the feeding frame 40201. The rotating frame 40202 can block either feeding chute 4020101 so that fruits and vegetables slide down from the other feeding chute 4020101. The driving component 40203 is provided on the feeding frame 40201 to drive the rotating frame 40202 to rotate.

[0031] This application uses a speed matching section 2 to create distance between the conveyed fruits and vegetables, specifically by setting the conveyor speed to be greater than the conveyor belt speed of the fruits and vegetables. A weighing section 3 weighs the conveyed fruits and vegetables and transmits the weight information to a rejection section 4, specifically through gravity sensing and photoelectric sensing. Finally, the rejection component 401 determines whether to feed the fruits and vegetables onto the unloading rack 40201 based on the weight information transmitted from the weighing section 3. When the fruits and vegetables in the fruit and vegetable basket at the outlet of any unloading chute 4020101 accumulate to a certain extent, the drive component 40203 is activated to rotate the rotating frame 40202, thereby blocking the unloading chute 4020101 and causing the fruits and vegetables to slide out from another unloading chute 4020101 into another fruit and vegetable basket. This achieves the goal of preventing the fruits and vegetables from falling to the ground or injuring the handler without needing to close the device.

[0032] Reference Figure 5 and Figure 6 The drive assembly 40203 includes a first linear driver 4020301 and a drive rod 4020302. The first linear driver 4020301 is hinged to the unloading frame 40201 away from its output end, and the drive rod 4020302 is coaxially arranged at its output end. The end of the drive rod 4020302 away from the first linear driver 4020301 is hinged to one side of the rotating frame 40202.

[0033] This application activates the first linear driver 4020301 to drive the drive rod 4020302 to extend and retract, thereby driving the rotating frame 40202 to rotate reciprocally.

[0034] Reference Figure 5 and Figure 6 The rotating frame 40202 is rotatably provided with a rotating wheel 4020201 and a transmission wheel 4020202 at opposite ends. The transmission belt 4020203 is sleeved on the rotating wheel 4020201 and the transmission wheel 4020202 at opposite ends. The rotating frame 40202 is also provided with a rotary driver 4020204 for driving the rotating wheel 4020201 to rotate.

[0035] This application prevents fruits and vegetables from accumulating and clogging on the feeding rack 40201 by activating the rotary driver 4020204 to drive the rotating wheel 4020201 to rotate via the transmission belt 4020203.

[0036] Reference Figure 5 The outer side of the 4020203 transmission belt is equipped with several actuating feeding blocks.

[0037] This application uses this design to prevent the transmission belt 4020203 from slipping between itself and the fruits and vegetables, thus preventing the fruits and vegetables from sliding out of the feeding chute 4020101.

[0038] Reference Figure 4 and Figure 5 A rotating ring groove 4020205 is provided at the rotatable connection between the rotating frame 40202 and the unloading frame 40201, and a rotating ring block 4020102 adapted to the rotating ring groove 4020205 is provided on the unloading frame 40201.

[0039] This application employs a design to ensure that the rotating frame 40202 can be stably rotatably mounted on the unloading frame 40201.

The second linear driver 40101 is disposed on one side of the conveyor frame 1, and the pusher frame 40102 is disposed at its output end facing the opening of the unloading frame 40201.

[0041] This application pushes fruits and vegetables onto the unloading rack 40201 by activating the second linear drive 40101 to extend and retract the pusher frame 40102.

[0042] Reference Figure 3 The rejection section 4 is equipped with a height restriction structure 403 on the side away from the weighing section 3.

[0043] This application achieves the multi-purpose nature of the device by setting a height limit frame 403 to sort larger fruits and vegetables onto the unloading rack 40201, and can also sort out larger fruits and vegetables.

[0044] Reference Figure 2 The conveyor frame 1 is provided with a control panel 101 on one side for controlling the speed matching section 2, the weighing section 3 and the rejection section 4.

[0045] This application uses the control panel 101 to control the speed matching section 2, the weighing section 3, and the rejection section 4, thereby realizing the linkage control and information transmission of multiple parts.

[0046] In use, the device provided by this utility model uses a speed matching section 2 to create distance between the conveyed fruits and vegetables, specifically by setting the conveying speed to be greater than the conveying speed of the conveyor belt carrying the fruits and vegetables; a weighing section 3 weighs the conveyed fruits and vegetables and transmits the weight information to a rejection section 4, specifically through gravity sensing and photoelectric sensing; finally, the rejection component 401 determines whether to feed the fruits and vegetables onto the unloading rack 40201 based on the weight information transmitted from the weighing section 3; when the fruits and vegetables in the fruit and vegetable frame at the outlet end of any unloading chute 4020101 accumulate to a certain extent, the drive component 40203 is activated to drive the rotating frame 40202 to rotate, thereby blocking the unloading chute 4020101 and causing the fruits and vegetables to slide out from another unloading chute 4020101 into another fruit and vegetable frame, so that the device does not need to be shut down and the fruits and vegetables will not fall to the ground or injure the handler.
