Description

A suction device for powder sieving machine

technical field

The invention belongs to the technical field of powder conveying devices, in particular to a material suction device for a powder sieving machine.

Background technique

3D printing has been widely used in military industry, aerospace, medicine, construction, automobile, electronics, clothing, jewelry and other fields. At present, when using PS (polyethylene) powder for 3D printing, fine particles will be formed after printing, so the powder needs to be re-sieved for use. All the powder sifters on the market need to manually add powder, which not only increases the workload of the staff, affects the efficiency, but also produces a lot of dust, which damages the health of the staff, pollutes the environment and causes waste. In addition, because the powder is manually pulled out from the 3D printer, residues are likely to be left on the corners, which will affect the effect of 3D printing again.

After retrieval, the patent applications related to the present invention include: a material suction pulverizer (publication number: CN204892093), and a suction pulverizer is invented, which is characterized in that it does not require manual feeding by an operator and is convenient to operate, but the The invention can only absorb material from a fixed point, but cannot move the material, which limits the working range.

Contents of the invention

The invention provides a material suction device to solve the problem that materials need to be manually removed from the 3D printer and manually added to the powder sieving machine during 3D printing.

A material suction device for a powder sifter, including a powder sieve, a clamp, a dust cover, a dust cloth, a material storage box, a suction pump, a steel plate, a suction pipe, a bracket, anchor bolts, a powder collection The barrel, rubber tube, and powder sieving machine are placed on the ground, the dust cover is placed on the powder sifter, clamped by the clamp, the dust cloth is connected to the dust cover and the storage box, the suction pump is fixed on the bracket, and the material is sucked One end of the tube is connected to the material storage box, the bracket is used to support the material storage box, and the bottom end of the bracket is fixed on the ground through anchor bolts.

Further, the material storage box is a trapezoidal box, which facilitates the falling of the powder material. There is a steel plate at a distance of 20mm from the bottom of the material storage box, and the steel plate can be freely pulled to control the falling speed of the powder material.

Further, the support is two 15mm thick steel plates, arranged at both ends of the storage box, the upper end of the steel plate and the storage box are fixed by welding, and the bottom end is fixed on the ground by anchor bolts.

Further, the suction pipe is made of soft plastic material, and there is a suction pump on the suction pipe. The suction pump is fixed on the bracket, and the other end is manually sucked by hand. The inlet of the suction pump is equipped with a one-way valve to prevent powder Backflow.

Further, the powder collecting bucket is equipped with a powder collecting bucket cover, which is made of transparent plastic, which can conveniently observe the powder content in the powder collecting bucket. The material port is connected, and the other end extends into the powder collecting bucket through the rectangular hole on the powder collecting bucket cover, which can effectively prevent the powder from floating during the falling process, which is not only harmful to the human body, but also causes waste and pollutes the environment.

The beneficial effects of the invention are: the material suction device avoids manual addition of powder, reduces the workload of workers, improves the efficiency of powder screening, reduces dust, protects the health of workers, and avoids waste. In addition, the suction device can clean the powder particles in the 3D printer, which is beneficial to improve the quality of the next 3D printing.
