Description

Weighing device for metal powder materials

technical field

The utility model relates to the technical field of metal powder processing, in particular to a weighing device for metal powder materials.

Background technique

In metal powder processing, metal powder is usually used as raw material. For example, in powder metallurgy, metal powder is taken through sintering and other molding processes to produce metal materials, composite materials, etc.; Quantitative weighing is a very important link. Only by accurately weighing metal powder raw materials can we ensure that the properties of metal products such as density, strength, and stiffness meet the requirements.

Traditional powder weighing methods are mostly done manually, requiring the operator to pour metal powder from a large powder bucket into a small bucket, and then scoop from the small bucket to a plate placed on the weighing device After weighing, pour it from the pan into the mold. Due to the smaller powder particles and lighter weight, during the above-mentioned weighing operation, the raised metal powder is easily inhaled by the operator into the lungs, causing greater damage to the human body. At the same time, manual operation still exists Low efficiency, serious material waste and other problems.

At this stage, there are also some powder weighing devices that can overcome the above problems. Specifically, pressure sensors are used to measure the weight of metal powder, but the structure is relatively complicated and the operation is inconvenient.

Utility model content

Aiming at the deficiencies of the prior art, the purpose of this utility model is to provide a weighing device for metal powder materials, which has simple structure, convenient operation, high efficiency and can avoid manual operation.

In order to achieve the above object, the utility model adopts the following technical solutions:

Weighing apparatus for metal powder materials, including,

A base, the base is provided with a first support column and a second support column respectively located on both sides of the base, and a pressure sensor is provided on the first support column;

A hopper arranged on the base, one side of the hopper is hinged to the second support column, and the other side is provided with a pressure plate abutting against the pressure sensor;

The storage tank is arranged directly above the hopper;

The screw feeding mechanism includes a feeding tube extending from the bottom surface of the storage tank to the opening of the hopper, a feeding screw placed in the feeding tube and pivotally connected to the storage tank, and a motor driving the feeding screw.

A mounting frame is arranged in the material storage barrel, the body of the motor is fixed on the mounting frame, and the top of the feeding screw is pivotally connected to the mounting frame through a bearing and synchronously connected with the rotating shaft of the motor.

The bottom wall of the material storage tank is conical with a low center and high edges, and the top of the feed pipe is connected to the middle part of the bottom wall.

The beneficial effects of the utility model are:

Compared with the prior art, the utility model can prevent the raised dust from being inhaled into the lungs of the operator, ensuring the personal safety of the operator. At the same time, the utility model has a simple structure, can accurately weigh the weight of the metal powder, and is easy to operate. Has higher efficiency.

detailed description

Below, in conjunction with accompanying drawing and specific embodiment, the utility model is described further:

As shown in Figure 1, it is a weighing device for a metal powder material of the present utility model, which includes a base 10, a hopper 20, a storage tank 30 and a screw feeding mechanism 40, and the base 10 is provided with a first support column 11 and The second support column 13, the first support column 11 and the second support column 13 are respectively located on both sides of the base 10, and a pressure sensor 12 is arranged on the top of the first support column 11; the hopper 20 is installed on the base 10, specifically One side of the hopper 20 is hinged on the second support column 13, and the other side is provided with a pressing plate 21, and the pressing plate 21 abuts on the pressure sensor 12, that is, abuts on the trigger end of the pressure sensor 12; the storage tank 30 Arranged directly above the hopper 20, the screw feeding mechanism 40 is used to transport the metal powder in the storage tank 30 into the hopper 20. The pipe 41 , the feeding screw 42 placed in the feeding pipe 41 and pivotally connected to the storage barrel 30 , and the motor 43 driving the feeding screw 42 .

When the utility model is in use, the metal powder is added to the storage barrel 30, the motor 43 is started, and the feeding screw 42 is driven to rotate, and the metal powder located in the storage barrel 30 is forced to pass through the feeding pipe 41 along with the rotation of the feeding screw 42. As the metal powder in the hopper 20 continues to increase, the pressure of the pressure plate 21 on the pressure sensor 12 also increases continuously. When the pressure reaches the set value, the pressure sensor 12 sends a signal to a controller , the controller controls the motor 43 to stop rotating, and now the quantitative weighing of the metal powder is completed. Compared with the prior art, the utility model can prevent the raised dust from being inhaled into the lungs of the operator, ensuring the personal safety of the operator. At the same time, the utility model has a simple structure, can accurately weigh the weight of the metal powder, and is easy to operate. Has higher efficiency.

In order to facilitate the installation of the motor 43 and the feeding screw 42, a mounting frame 31 is arranged in the above-mentioned storage tank 30, the body of the motor 43 is fixed on the mounting frame 31, and the top of the feeding screw 42 is pivotally connected to the mounting frame 31 through a bearing. And be connected synchronously with the rotating shaft of motor 43.

In addition, the bottom wall of the storage tank 30 is conical with a low middle and high edges, and the top of the feeding pipe 41 is connected to the middle of the bottom wall, so that the metal powder can smoothly enter the feeding pipe 41 when being squeezed. middle.
