Description

Technical Field

[0001] The utility model relates to the technical field of rice weighing and packaging, in particular to a rice weighing and packaging device. Background Art

[0002] At present, rice weighing and packaging devices play an important role in the field of grain processing and packaging. Although most of the existing rice weighing and packaging devices on the market can realize basic weighing and packaging functions, they still have some obvious shortcomings in practical applications.

[0003] First, existing devices often cannot adapt to packaging bags of different heights, which requires operators to perform tedious manual adjustments every time they change packaging bags, greatly reducing work efficiency. Second, existing devices often lack effective clamping of the bag opening during the packaging process, which causes the packaging bag to easily slip or the bag opening to spread when filling rice, affecting the accuracy and efficiency of packaging.

[0004] Therefore, it is necessary to design a rice weighing and packaging device that can be raised and lowered to match packaging bags of different heights and has a bag opening clamping mechanism to solve the shortcomings of the existing technical solutions. Utility Model Content

[0005] The purpose of the utility model is to provide a rice weighing and packaging device to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rice weighing and packaging device, comprising a base frame, a top frame and an electronic quantitative scale, two groups of hydraulic push rods are installed inside the base frame, a top frame is arranged on the top of the base frame, the output end of the hydraulic push rod is fixed to the bottom end of the top frame, an electronic quantitative scale is arranged inside the top frame, a discharge port is installed at the bottom of the electronic quantitative scale, a mounting frame is installed outside the electronic quantitative scale, two clamping arms are installed on both sides of the mounting frame through a rotating shaft, and an electric push rod is arranged between the two clamping arms through a rotating shaft.

[0007] When in use, rice is put into the electronic quantitative scale from the top. The electronic quantitative scale is a kind of electronic quantitative scale widely used in agricultural production, scientific research, seed processing and other fields in the prior art. Its main function is to accurately weigh the specified weight of the product according to the needs of the user. This weighing process is usually automated and can be accurately controlled by an electrical control system to ensure the accuracy of each weighing. The packaging bag is placed directly below the electronic quantitative scale, and the weighed rice is discharged into the bag through the discharge port. In this process, the bottom of the clamping arm can be squeezed toward the middle by the contraction of the electric push rod to clamp the mouth of the rice bag to facilitate the entry of rice. The height of the electronic quantitative scale can be controlled by the extension and retraction of the hydraulic push rod so as to be suitable for packaged rice bags of different heights and batches, thereby improving the versatility of the device. The electronic quantitative scale adopts technical means known to existing technicians, so it is not described in detail in the manual.

[0008] Preferably, the hydraulic push rod, the electronic quantitative scale and the electric push rod are all electrically connected to the peripheral control unit, and a bracket is installed at the bottom of the chassis.

[0009] Since the hydraulic push rod, electronic quantitative scale and electric push rod are all electrically connected to the external control unit, the external control unit can control the coordinated operation of the internal electrical equipment of the device, and the design of the bracket can improve the stability of the device when it is placed.

[0010] Preferably, a telescopic rod is installed at the bottom of the top frame, and the telescopic rod is movably extended to the inside of the hydraulic push rod.

[0011] The telescopic rod can move inside the bottom frame, and the top frame is connected to the bottom frame through the telescopic rod, so as to increase the stability of the top frame when it is vertically lifted or lowered.

[0012] Preferably, a feed hopper is installed on the top of the electronic quantitative scale.

[0013] Rice can be put in through the feed hopper, and the electronic quantitative scale can accurately weigh the rice, and the weighed rice can be discharged from the discharge port for subsequent packaging operations.

[0014] Preferably, a clamping plate is installed at the bottom of the clamping arm.

[0015] The design of the clamping plate enables the clamping arm to better clamp the rice packaging bag, so that the rice packaging operation can proceed steadily.

[0016] In summary, this application includes the following beneficial technical effects:

[0017] 1. During the weighing process, the utility model can squeeze the bottom of the clamping arm toward the middle through the contraction of the electric push rod to clamp the mouth of the rice bag, making it convenient for rice to enter, ensuring the stability of the packaging bag when filling the rice, effectively preventing the bag mouth from spreading or the packaging bag from slipping, and improving the accuracy and efficiency of packaging.

[0018] 2. When the height needs to be adjusted, the utility model can be controlled by extending and retracting the hydraulic push rod, so that the device can adapt to packaging bags of different heights, without the need for frequent manual adjustments by the operator, thereby improving work efficiency.
