[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides an automatic weighing machine, such as Figure 1-Figure 5 As shown, it includes a loading module 1 for temporary storage and belt conveyor loading. The top of the loading module 1 is connected to a conveying module 2. A weighing module 3 is arranged at the bottom of one end of the conveying module 2 for receiving weight changes and feeding back to a weighing control panel 6. A finished product conveyor 5 is installed on the top of the weighing module 3. The conveying module 2 includes a frame 205. A lower conveyor belt 203 and an upper conveyor belt 204 are installed on the inner side of the frame 205. The lower conveyor belt 203 and the upper conveyor belt 204 are arranged in parallel. The width of the lower conveyor belt 203 is greater than that of the upper conveyor belt 204. The lower conveyor belt 203 is responsible for rapid canning to a certain value below the calibration value, and the upper conveyor belt 204 is responsible for accurate canning to a target value. An upper box module 4 is arranged on the outer side of one end of the finished product conveyor 5.

[0024] In this embodiment, the feeding module 1 includes a feeding conveyor belt, and feeding guard plates 101 are installed on both sides of the feeding conveyor belt to prevent the upper material from falling to the ground due to instability. A feeding storage bin 103 is installed at the bottom end of the feeding conveyor belt. With the transportation of the conveying module 2, the conveyor belt in the feeding module 1 starts and stops. When there is a lot of material, part of the raw materials are temporarily stored. A feeding flow limiting plate 102 is installed above the bottom of the feeding conveyor belt to prevent excessive feeding.

[0025] Specifically, a control cabinet 201 is installed below the conveying module 2 for installing other electrical equipment.

[0026] Furthermore, the upper box module 4 includes a horizontal conveyor belt, on which are installed several infrared sensors, which monitor the position of the carton through the infrared sensors, thereby transmitting the data to the weighing control panel 6, and controlling the horizontal conveyor belt through the weighing control panel 6 so that the discharge end of the conveying module 2 is facing the center of the carton.

[0027] Furthermore, a flow limiting paddle 202 is installed in the middle of the upper part of the upper conveyor belt 204. The flow limiting paddle 202 is installed on a side panel of the frame 205 close to the upper conveyor belt 204, and there is a 1mm gap between the bottom and the upper conveyor belt 204, which is used to reduce the feeding quantity and density in the precise canning stage to gradually reach the target value.

[0028] Furthermore, the weighing module 3 is located below the discharge end of the conveying module 2 , and the weighing module 3 includes a bottom frame 301 , a weighing sensor 302 is installed on the top of the bottom frame 301 , and an upper frame 303 is installed on the top of the weighing sensor 302 .

[0029] Furthermore, the finished product conveyor 5 is installed on the upper rack 303, and cartons are placed on the top of the finished product conveyor 5. The finished product conveyor 5 is flush with the upper box module, which is convenient for receiving the cartons provided by the upper box module 4 before weighing begins. After weighing, the finished products are conveyed to the roller module at the other end of the finished product conveyor 5 or the customer's platform.

[0030] Furthermore, a weighing control panel 6 is installed at the outer end of the frame 205 of the conveying module 2 for data display and control.

[0031] When the automatic weighing machine of the utility model is used, the dried fruit and vegetable raw materials are first stored in the feeding storage bin 103 of the feeding module 1. When feeding is required, the feeding conveyor belt is started to convey the raw materials from the storage bin. In this process, the feeding guard plate 101 effectively prevents the raw materials from falling from both sides of the conveyor belt, and the feeding flow limiting plate 102 ensures the uniformity of feeding and prevents excessive feeding at one time.

[0032] Next, the raw materials enter the conveying module 2. The conveying module 2 consists of a lower conveyor belt 203 and an upper conveyor belt 204, which are arranged in parallel and the width of the lower conveyor belt 203 is greater than that of the upper conveyor belt 204. In the initial stage, the lower conveyor belt 203 runs quickly and quickly fills the raw materials to a certain value below the calibration value. Subsequently, the upper conveyor belt 204 starts to fill the raw materials to the target value in a more precise manner. In this process, the flow limiting paddle 202 plays a key role, which reduces the amount and density of the material to be fed, thereby ensuring the accuracy of the filling.

[0033] The loading module 4 is also in operation. It monitors the position of the carton through a horizontal conveyor belt and several infrared sensors. When the carton moves to the appropriate position, the infrared sensor transmits this information to the weighing control panel 6. The weighing control panel 6 then controls the horizontal conveyor belt to ensure that the discharge end of the conveying module 2 is facing the center of the carton and the material is filled into the carton.

[0034] During filling, the weighing module 3 is used for weighing. The weighing sensor 302 can accurately measure the weight of the raw material and feed this information back to the weighing control panel 6. When the raw material filling reaches the predetermined weight, the finished product is conveyed to the roller module at the other end of the finished product conveyor 5 or the customer's platform, and the filling of the next carton is started.

[0035] Finally, it should be noted that the electronic components in the upper box module 4, finished product conveyor 5, etc. in this embodiment are all universal standard parts or parts known to technical personnel in this field, and their structures and principles can be known to technical personnel in this field through technical manuals or through conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components are connected by wires respectively. The specific connection means should refer to the working sequence between the electrical components in the above-mentioned working principle to complete the electrical connection, which are all well-known technologies in the field.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
