Description

Technical Field

[0001] This utility model belongs to the field of quantitative weighing technology, specifically relating to an automated quantitative weighing device for powder materials. Background Technology

[0002] Aluminum powder, commonly known as "silver powder," is a silvery-white metallic pigment. It is essentially made by adding a small amount of lubricant to pure aluminum foil, crushing it into a scaly powder, and then polishing it. After production, aluminum powder generally needs to be filled into corresponding packaging bags by workers. The traditional method is for workers to weigh it manually, which is inefficient and may even cause the aluminum powder to scatter. It is also difficult for workers to accurately weigh the powder manually, requiring them to repeatedly place the packaging bags containing aluminum powder on the weighing structure for weighing, which is quite cumbersome. Therefore, a device that can weigh aluminum powder quantitatively is needed.

[0003] Chinese patent CN205931317U discloses an automated packaging production line aluminum powder quantitative weighing device. It includes a hopper with a guide pipe connected to its lower part. A screw conveyor is installed inside the guide pipe, with a large pulley connected to one end of the screw conveyor. The large pulley is connected to a small pulley via a transmission belt, and a servo motor is connected to the small pulley. A discharge port is located at the lower side of one end of the guide pipe, and a fixed frame is connected to the lower side of the discharge port. A hopper is suspended below the fixed frame, and a weighing sensor is installed between the fixed frame and the hopper. A conveying device is located below the hopper. This invention has the advantages of reasonable structure, simple installation, and convenient operation, achieving automated operation and reducing labor intensity.

[0004] However, while the above-mentioned technical solution can achieve the purpose of weighing aluminum powder, it requires workers to place the packaging bag on the flange of the hopper and then fix it with a corresponding fixing structure. However, after the packaging bag is filled with a certain amount of aluminum powder, workers need to support the packaging bag containing aluminum powder beforehand and then loosen the edge of the packaging bag fixed on the flange of the hopper. This makes it difficult for workers to operate, and one-handed operation can easily cause the packaging bag containing aluminum powder to tip over, resulting in aluminum powder spillage and increasing the difficulty of cleanup. Therefore, it has certain limitations in use. Utility Model Content

[0005] The purpose of this invention is to provide an automated powder quantitative weighing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An automated powder quantitative weighing device includes: a base, a feeding chamber fixedly connected to one side of the top of the base, a material hopper fixedly and penetrating the interior of the feeding chamber, a support platform fixedly connected to one side of the inner bottom wall of the base, a weighing sensor fixedly connected to the top of the support platform, protective plates fixedly connected to both sides of the top of the weighing sensor, a hydraulic telescopic rod fixedly connected to the inner side wall of the protective plate, a first sleeve fixedly connected to the output end of the hydraulic telescopic rod, the first sleeve slidably connected to the top of the weighing sensor, an L-shaped rod fixedly connected to the surface of the first sleeve, an electric slide rail fixedly connected to one side of the L-shaped rod, an electric slider slidably connected inside the electric slide rail, a connecting rod fixedly connected to one side of the electric slider, a connecting rod fixedly connected to the bottom end of the connecting rod, a pressing ring fixedly connected to the top end of the connecting rod, and a second sleeve slidably connected to one side of the top of the weighing sensor.

[0008] Preferably, an electric push rod is fixed inside and passes through the base, and a push plate is fixedly connected to the output end of the electric push rod.

[0009] Preferably, the base has a conveying groove inside, and a conveyor belt is fixedly connected inside the conveying groove.

[0010] Preferably, a protective shell is fixedly connected to the middle of the top of the hopper, a drive motor is fixedly connected inside the protective shell, a transmission rod is fixedly connected to the output end of the drive motor, and a conveying auger is fixedly connected to the bottom end of the transmission rod.

[0011] Preferably, a guide platform is fixedly connected to one side of the protective plate, and seven guide rollers are rotatably arranged on the inner bottom wall of the guide platform.

[0012] Preferably, the surface of the hopper has two observation ports, a feeding port is fixedly connected to one side of the top of the hopper, a sealing cap is threaded onto the surface of the feeding port, and a sealing door is connected to the back of the base via a hinge.

[0013] Preferably, a control panel is fixedly connected to the top of one side of the base surface, and the control panel is electrically connected to the weighing sensor, the hydraulic telescopic rod, the electric slide rail, the electric push rod, the conveyor belt and the drive motor respectively.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) By automating the weighing and filling process, the tediousness and error of manual weighing are avoided, and the weighing efficiency and accuracy are significantly improved. The weighing sensor monitors the weight of aluminum powder in the packaging bag in real time. When the preset value is reached, the filling is automatically stopped, ensuring the consistency of the weight of each bag of aluminum powder. The device realizes automated operation, reduces the number of manual operation steps for staff, and reduces labor intensity. Staff only need to put the packaging bag on the sleeve tube. The subsequent weighing, filling and separation processes are all completed automatically by the device. The operation is simple. The pressing ring presses the top of the packaging bag against the protruding edge of the sleeve tube, preventing the aluminum powder from spilling during the filling process. It avoids the problem of the packaging bag tipping over and aluminum powder spilling due to single-handed operation when the staff unpacks the edge of the packaging bag, and reduces the difficulty of cleaning work.

[0016] (2) When the packaging bag is transferred to the conveyor belt after being filled with aluminum powder, the guide table can play a certain guiding role. At the same time, the guide roller can make its movement smoother and avoid jamming and packaging bag accumulation. Attached Figure Description

Detailed Implementation

[0022] 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.

[0023] Example 1:

[0024] Please see Figures 1 to 4As shown, an automated powder quantitative weighing device includes a base 1. A feeding chamber 2 is fixedly connected to one side of the top of the base 1. A hopper 3 is fixedly connected inside and passes through the feeding chamber 2. A support platform is fixedly connected to one side of the inner bottom wall of the base 1. A weighing sensor 4 is fixedly connected to the top of the support platform. Protective plates 5 are fixedly connected to both sides of the top of the weighing sensor 4. A hydraulic telescopic rod 6 is fixedly connected to the inner side wall of the protective plate 5. A first set of feeding cylinders 7 is fixedly connected to the output end of the hydraulic telescopic rod 6 and is slidably connected to the top of the weighing sensor 4. An L-shaped rod is fixedly connected to the surface of the first set of feeding cylinders 7. An electric slide rail 8 is fixedly connected to one side of the L-shaped rod. An electric slider is slidably connected inside the electric slide rail 8. A connecting rod is fixedly connected to one side of the electric slider. A connecting rod 9 is fixedly connected to the bottom end of the connecting rod. A pressing ring 10 is fixedly connected to the top end of the connecting rod 9. A second set of feeding cylinders is slidably connected to one side of the top of the weighing sensor 4.

[0025] The feeding chamber 2 allows the aluminum powder inside the hopper 3 to flow downwards, while also providing some support to the hopper 3. The weighing sensor 4 detects the weight of the aluminum powder inside the packaging bag. The protective plate 5 secures the hydraulic telescopic rod 6. It should be noted that the hydraulic telescopic rod 6 is fixed to the inner wall of the protective plate 5 near the first set of feeding cylinders 7. The hydraulic telescopic rod 6 provides a certain pushing force for the movement of the first set of feeding cylinders 7. The second set of feeding cylinders and the first set of feeding cylinders 7 form a closed cylindrical tube, facilitating the wrapping of the packaging bag. The first set of feeding cylinders 7 and the second set of feeding cylinders... The top edge of the tube has a flat protrusion, which makes it easy to roll the top of the packaging bag onto its surface. The electric slide rail 8 drives the electric slider to move up and down, which in turn causes the connecting rod to move up and down, then the connecting rod 9 to move up and down, and finally the pressing ring 10 to move up and down, pressing the rolled-up packaging bag, which then facilitates the filling of aluminum powder. The other side of the inner wall of the protective plate 5 is also fixedly connected to a hydraulic telescopic rod 6, and the output end of the hydraulic telescopic rod 6 is fixedly connected to the surface of the second set of tubes, which facilitates its movement and makes it easy to separate the first set of tubes 7 and the second set of tubes.

[0026] An electric push rod 11 is fixed inside and passes through the base 1, and a push plate 12 is fixedly connected to the output end of the electric push rod 11. The electric push rod 11 is designed to drive the push plate 12 to move left and right, thereby making it easier to push the packaging bag to the right after it has been filled with aluminum powder.

[0027] The base 1 has a conveying groove 13 inside, and a conveyor belt 14 is fixedly connected inside the conveying groove 13. The opening of the conveying groove 13 allows the conveyor belt 14 to be fixed inside, and the conveyor belt 14 can transport the packaging bag containing aluminum powder after it falls.

[0028] A protective shell is fixedly connected to the center of the top of the hopper 3. A drive motor 15 is fixedly connected inside the protective shell. A transmission rod is fixedly connected to the output end of the drive motor 15. A conveying auger 16 is fixedly connected to the bottom end of the transmission rod. The drive motor 15 provides a certain driving force for the rotation of the transmission rod, which in turn drives the conveying auger 16 to rotate, facilitating the downward conveying of aluminum powder.

[0029] A guide platform 17 is fixedly connected to one side of the protective plate 5, and seven guide rollers 18 are rotatably installed on the inner bottom wall of the guide platform 17. The guide platform 17 provides a certain guiding effect when the packaging bag containing aluminum powder is pushed downwards, and the guide rollers 18 make its movement smoother.

[0030] Two observation ports are provided on the surface of the hopper 3. A feeding port is fixedly connected to one side of the top of the hopper 3, and a sealing cap is threaded onto the surface of the feeding port. A sealing door is connected to the back of the base 1 via a hinge. The observation ports allow workers to observe the amount of aluminum powder inside the hopper 3, the feeding port facilitates the subsequent addition of aluminum powder, and the sealing door allows workers to close the packaged bags containing aluminum powder. The packaging bags can be constructed with interlocking button buckles on both sides of the inner wall. The top of both sides of the inner wall of the packaging bag is provided with matching grooves and protrusions. When the two sides are pressed together, the protrusions insert into the grooves, thereby securing the packaging bag. This is existing technology and will not be described in detail.

[0031] A control panel is fixedly connected to the top of one side of the base 1, and the control panel is electrically connected to the weighing sensor 4, the hydraulic telescopic rod 6, the electric slide rail 8, the electric push rod 11, the conveyor belt 14 and the drive motor 15 respectively.

[0032] The working principle of this utility model is as follows: The operator first opens the sealed door, then places the packaging bag over the protrusions on the upper edges of the first and second sleeve cylinders 7 and 8. The operator then controls the electric slide rail 8 to lower the electric slider, which in turn lowers the connecting rod and linking rod 9. This causes the linking rod 9 to lower the pressing ring 10, pressing the top of the packaging bag onto the protrusions on the edges of the two sleeve cylinders. The operator then closes the sealed door and controls the drive motor 15 and conveyor belt 14. The output of the drive motor 15 rotates the transmission rod, which in turn rotates the conveyor auger 16, causing the aluminum powder inside the hopper 3 to be conveyed downwards. Once a certain amount of aluminum powder is placed inside the packaging bag and reaches the preset value of the weighing sensor 4, a signal is transmitted to the control panel. The control panel then controls the drive motor 15 to stop working. At this time, the operator opens the sealing door, lifting the top two sides of the inner wall of the packaging bag, causing the pressing buckle structure to engage. Then, the hydraulic telescopic rod 6 is activated, and the output ends of the two hydraulic telescopic rods 6 drive the first set of feeding cylinders 7 to separate from the second set of feeding cylinders. Subsequently, the electric push rod 11 is activated, and the output end of the electric push rod 11 drives the push plate 12 to move to the right, causing it to roll downwards through the guide table 17 and guide roller 18, moving it onto the conveyor belt 14. The operator can then collect it using the appropriate device.
