Ascending and descending mechanism of 3D printer and ascending and descending method thereof

Abstract

The invention discloses an ascending and descending mechanism of a 3D printer and an ascending and descending method thereof. The ascending and descending mechanism of the 3D printer comprises a support seat, wherein a high-elasticity rubber buffer pad is fixedly connected to the middle of the upper surface of the support seat; a support plate is also fixedly connected to the upper surface of thehigh-elasticity rubber buffer pad; vibration reduction springs are fixedly connected between the support plate and the support seat; the upper surface of the support plate is fixedly connected to a printing cabin; a fixing plate is fixedly connected to the lower surface of the inside of the printing cabin; the two ends of the fixing plate are fixedly connected with a rotating seat; a lead screw isrotationally connected onto the rotating seat; a motor is fixedly connected to a position, corresponding to the lead screw, of one side of the printing cabin; the output end of the motor is fixedly connected with the lead screw; a printing platform is glidingly connected inside the support seat; the lower surface of the printing platform is fixedly connected with a slide plate; a first slide block is glidingly connected inside the slide plate; and two sliding seats are rotationally connected onto the lead screw. The ascending and descending mechanism has the advantages that the use is convenient; the structure is simple; the ascending and descending movement is stable; the printing effect is not influenced; meanwhile, a spray head can be conveniently dismounted and repaired; and the vibration reduction effect is good.

Description

technical field [0001] The invention relates to the technical field related to 3D printers, in particular to a 3D printer lifting mechanism and a lifting method thereof. Background technique [0002] 3D printer, also known as three-dimensional printer, is a kind of cumulative manufacturing technology, that is, a machine of rapid prototyping technology. It is based on a digital model file, using special wax, powdered metal or plastic and other bondable materials. Print layers of adhesive materials to make three-dimensional objects. At present, three-dimensional printers are used to manufacture products. The existing 3D printers need to adjust the height of the printing platform when using them. However, the existing lifting mechanism is inconvenient to use. , the structure is complex, the lifting movement is unstable, which affects the printing effect. At the same time, the nozzle is prone to clogging, which is not easy to disassemble and maintain. It is easy to design a 3D p...

[0002] 3D printer, also known as three-dimensional printer, is a kind of cumulative manufacturing technology, that is, a machine of rapid prototyping technology. It is based on a digital model file, using special wax, powdered metal or plastic and other bondable materials. Print layers of adhesive materials to make three-dimensional objects. At present, three-dimensional printers are used to manufacture products. The existing 3D printers need to adjust the height of the printing platform when using them. However, the existing lifting mechanism is inconvenient to use. , the structure is complex, the lifting movement is unstable, which affects the printing effect. At the same time, the nozzle is prone to clogging, which is not easy to disassemble and maintain. It is easy to design a 3D printer lifting mechanism here to solve the above problems.
