Description

Technical Field

[0001] This utility model relates to the technical field of weighing and packaging devices, specifically a high-purity material anti-mixing impurity purification weighing and packaging device. Background Technology

[0002] Solid powders include both metallic and non-metallic powders. Metallic powders mainly include copper-based and iron-based metal powders, as well as powders of Sn, Zn, Al, Ni, Co, and Ag. Non-metallic powders mainly include graphite powder, organic pharmaceutical powders, non-metallic mineral powders, and food powders. The manufacturing processes for these powders are diverse. For example, the production methods for metallic powders mainly include electrolysis, atomization, reduction, diffusion sintering, wet processing, and mechanical methods; the production methods for non-metallic powders mainly include chemical methods, mechanical methods, and granulation methods. Regardless of the method, the metering and packaging of powder products is the final and crucial step in the production process. The main types of powder packaging include: iron drums lined with plastic bags, cardboard boxes lined with plastic bags, vacuum packaging using aluminum foil and plastic bags, and ton bags (such as woven plastic bags).

[0003] For example, the authorization announcement number CN104058114A discloses a packaging device for metal or non-metal powders, in which the lower part of the hopper is connected to the inlet end of a screw feeder, a stepper motor is connected to the outlet end of the screw feeder through a discharge device, and a packaging device is installed below the discharge pipe of the lower part of the discharge device.

[0004] This invention relates to a packaging device for metal or non-metal powders. It enables quantitative or semi-quantitative packaging of metal or non-metal powder products. The entire device can be configured according to specific production conditions. It is simple to process and install, easy to operate, and easy to automate, thereby reducing the labor intensity of workers and ensuring powder quality.

[0005] As can be seen from the solutions disclosed in the existing patent documents, there is a drop distance between the unloading device and the packaging device. When the powdered material falls from the unloading device into the packaging device, a large amount of dust will be raised, polluting the surrounding environment and endangering the health of the operators. In addition, it is inconvenient to dry the water stains inside the hopper, which leads to the powdered material clumping and reduced flowability, thereby causing problems such as material blockage and unstable conveying volume. Therefore, it is necessary to improve the existing technology. Utility Model Content

[0010] Preferably, the lower end face of the cover plate is in close contact with the material bucket, and a cloth bag is inserted inside the material bucket.

[0011] Preferably, the upper end of the hopper is provided with an annular pipe, and the inner wall of the upper end of the hopper is tightly attached with an air outlet pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This high-purity material anti-mixing impurity purification weighing and packaging device uses a connecting ring to clamp the discharge pipe and the outside of the screw, and rotates the tightening nut to drive the gasket to press the connecting ring to the outside of the discharge pipe, which facilitates quick and easy installation of the cloth bag. The design of the cloth bag and cover plate can shield the powdery high-purity material from being transported into the material bucket, preventing dust from flying and polluting the surrounding environment and harming the health of the operator.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-3 The diagram illustrates a high-purity material anti-mixing impurity purification weighing and packaging device, comprising a hopper 1, a conveying mechanism on one side of the hopper 1 for conveying high-purity materials, a conveying cylinder 11 on one side of the hopper 1, and a motor 12 on one side of the conveying cylinder 11. The shaft of the motor 12 is connected to an auger 13, which serves as the power source for the auger conveying. The rotating helical blades push the material along the inner wall of the conveying cylinder 11. Due to its own weight and the friction of the casing, the material does not rotate synchronously with the blades. It moves along a spiral path to convey high-purity materials. A discharge pipe 14 is provided at the lower end of the conveying cylinder 11. Screws 15 are symmetrically arranged on the outer side of the lower end of the discharge pipe 14. A gasket 16 is sleeved on the outer side of the screw 15. A nut 17 is threadedly connected to the outer side of the screw 15. A connecting ring 18 is sleeved on the outer side of the screw 15. A cloth bag 19 is connected to the lower end of the connecting ring 18. A cover plate 110 is connected to the outer side of the cloth bag 19. The lower end of the cover plate 110 covers the material barrel 111. An electronic scale 112 is placed on the lower end of the material barrel 111. Electronic scale 112 working process: Gravity transfer: After the object is placed on the weighing pan, the load-bearing system applies gravity to the weighing sensor through the force transmission mechanism.

[0017] Signal conversion: When the load cell is subjected to force, it deforms, causing changes in its internal resistance and voltage, and outputs an analog signal proportional to the weight.

[0018] Signal processing: After analog signals are amplified, filtered, zeroed, etc., they are converted into digital signals by analog-to-digital converters.

[0019] Data processing and display: Digital signals are input to the microprocessor, and after processing in combination with preset programs and keyboard commands, the results are transmitted to the display for intuitive presentation.

[0020] A drying mechanism is provided on the outside of the hopper 1. The drying mechanism is used to dry the inside of the hopper 1 and the conveying cylinder 11. The drying mechanism includes a dryer 2 provided on one side of the hopper 1. A drying pipe 21 is connected to one side of the dryer 2. A drying pipe 22 is connected to the upper end of the drying pipe 21. An annular pipe 23 is connected to the upper end of the drying pipe 22. An air outlet pipe 24 is provided at the lower end of the annular pipe 23.

[0021] Please see Figure 1-3 The auger 13 is internally connected to the hopper 1, and the auger 13 is internally connected to the conveying cylinder 11; With this setup, the auger 13 is driven to rotate by starting the motor 12, thereby conveying the high-purity material inside the hopper 1 through the conveying cylinder 11, the discharge pipe 14 and the cloth bag 19 to the inside of the material barrel 111 for easy loading.

[0022] Please see Figure 1 and Figure 3 The inner side of the nut 17 presses against the washer 16, the inner side of the washer 16 presses against the connecting ring 18, and the inside of the connecting ring 18 is tightly attached to the discharge pipe 14. With this setup, by attaching the connecting ring 18 to the outside of the discharge pipe 14 and the screw 15, and by rotating the tightening nut 17, the washer 16 is pressed against the outer side of the discharge pipe 14, making it easy to quickly and securely install the cloth bag 19.

[0023] Please see Figure 1 and Figure 3 The lower end face of the cover plate 110 is in close contact with the material bucket 111, and the inside of the material bucket 111 is fitted with a cloth bag 19; With this setup, the bag 19 and cover 110 are designed to shield the powdery high-purity material as it is conveyed into the hopper 111, preventing dust from drifting, polluting the surrounding environment, and harming the operator's health.

[0024] Please see Figure 1 An annular pipe 23 is provided at the upper end of the hopper 1, and the inner wall of the upper end of the hopper 1 is tightly attached to the air outlet pipe 24. With this setup, by starting the dryer 2, hot air is delivered into the drying pipe 1 21 and the drying pipe 22, thereby drying the inside of the conveying cylinder 11 and the hopper 1. This prevents water stains from adhering to the inside of the conveying cylinder 11 and the hopper 1, which would cause the powdered material to clump together, reduce its flowability, and lead to problems such as material blockage and unstable conveying volume.

[0025] The working principle of this embodiment is as follows: This high-purity material anti-mixing impurity purification weighing and packaging device uses the connecting ring 18 to clamp the discharge pipe 14 and the outside of the screw 15, and rotates the tightening nut 17 to drive the washer 16 to press the connecting ring 18 to the outer side of the discharge pipe 14, which facilitates quick and easy installation of the cloth bag 19. The design of the cloth bag 19 and the cover plate 110 can shield the powdery high-purity material from being transported into the material barrel 111, preventing dust from flying and polluting the surrounding environment and harming the operator's health.

[0026] By starting the motor 12 to drive the auger 13 to rotate, the high-purity material inside the hopper 1 is transported to the material barrel 111 through the conveying cylinder 11, the discharge pipe 14 and the cloth bag 19, which facilitates the loading of materials.

[0027] As the amount of high-purity material inside the material hopper 111 increases, the value of the electronic scale 112 increases accordingly. When the value reaches the expected weight, the motor 12 and the auger 13 stop running, thus completing the loading and weighing process for subsequent sealing and encapsulation.

[0028] By starting the dryer 2, hot air is delivered into the drying pipe 1 21 and the drying pipe 22, thereby drying the inside of the conveying cylinder 11 and the hopper 1. This prevents water stains from adhering to the inside of the conveying cylinder 11 and the hopper 1, which would cause the powdered material to clump together, reduce its flowability, and lead to problems such as material blockage and unstable conveying volume.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
