Device and method for nozzle adjustment
A nozzle adjustment device for a three-dimensional forming equipment assembly includes a first guiding block, a second guiding block, and a moving block. The first guiding block has a first inclined surface and a first bottom surface which is parallel to a printing platform. The first inclined surface and the first bottom surface form an acute angle therebetween. The second guiding block has a second inclined surface. The moving block is located between the first guiding block and the second guiding block. The moving block has a third inclined surface, a fourth inclined surface, and a second bottom surface. The second bottom surface is parallel to the printing platform, and has a nozzle disposed thereon.
1. A nozzle adjustment device for a three-dimensional forming equipment assembly, the nozzle adjustment device comprising:
a first guiding block having a first inclined surface and a first bottom surface which is parallel to a printing platform, the first inclined surface and the first bottom surface forming an acute angle therebetween;
a second guiding block having a second inclined surface; and
a moving block located between the first guiding block and the second guiding block, the moving block having a third inclined surface, a fourth inclined surface, and a second bottom surface which is parallel to the printing platform and has a nozzle disposed thereon.
2. The nozzle adjustment device of claim 1 , wherein the first inclined surface, the second inclined surface, the third inclined surface, and the fourth inclined surface are parallel to each other, and the third inclined surface contacts the first inclined surface, and the fourth inclined surface contacts the second inclined surface.
3. The nozzle adjustment device of claim 1 , further comprising a position-limiting device configured to limit a shortest limiting distance between the second bottom surface of the moving block and the printing platform.
4. The nozzle adjustment device of claim 3 , wherein when a distance between the second bottom surface of the moving block and the printing platform is the shortest limiting distance, the nozzle is located at a printing position.
5. The nozzle adjustment device of claim 3 , wherein the position-limiting device is a limiting block, a top surface of the limiting block is located above the printing platform by the shortest limiting distance, and when a distance between the second bottom surface of the moving block and the printing platform reaches the shortest limiting distance, the second bottom surface and the top surface of the limiting block are in contact.
6. The nozzle adjustment device of claim 1 , further comprising a driving device connected to the moving block and configured to drive a displacement of the moving block between the first guiding block and the second guiding block.
7. The nozzle adjustment device of claim 6 , wherein the driving device comprises an electric motor and a driving element driven by the electric motor, and the driving element is connected to the moving block.
8. A nozzle adjustment method for a three-dimensional forming equipment assembly, suitable for use in the nozzle adjustment device of claim 1 , the nozzle adjustment method comprising:
controlling a displacement of the moving block between the first guiding block and the second guiding block, so as to allow the nozzle installed on the second bottom surface of the moving block to carry out printing when a distance between the second bottom surface of the moving block and the printing platform is a shortest limiting distance; and
moving the moving block between the first guiding block and the second guiding block after the nozzle installed on the second bottom surface of the moving block stops printing, so as to make the distance between the second bottom surface of the moving block and the printing platform greater than the shortest limiting distance.
9. The nozzle adjustment method of claim 8 , wherein the nozzle adjustment device comprises a position-limiting device, and when the distance between the second bottom surface of the moving block and the printing platform is the shortest limiting distance, the second bottom surface and a top surface of the position-limiting device are in contact.
10. A three-dimensional forming equipment assembly comprising:
a frame;
a printing platform;
a motor assembly; and
a nozzle assembly connected to the motor assembly, the nozzle assembly comprising:
the nozzle adjustment device of claim 1 ; and
at least two nozzles including a first nozzle and a second nozzle, the first nozzle defined by the nozzle disposed on the second bottom surface.
11. The three-dimensional printing equipment assembly of claim 10 , wherein the second nozzle is fixed and connected to the motor assembly.
