Adjustable wire extrusion monitoring alarm device

Abstract

The invention discloses an adjustable wire extrusion monitoring alarm device. The device consists of a wire extrusion monitoring component, a tensioning regulation component and a motor component. Thewire extrusion monitoring component comprises a grooved wire extrusion wheel and a wire extrusion wheel without groove, a limit screw rod is inserted in the wire extrusion wheel, a code disc is fixedon a step at the end of the limit screw rod, holes are evenly distributed on the code disc, a photoelectric switch signal can be emitted after rotation of the code disc, through computing processingof the signal, wire material monitoring of the wire extrusion system can be realized. The tensioning regulation component comprises two tension springs arranged inside a motor support, a tensioning support is sleeved to one ends of the tension springs, a screw hole and a blind hole are respectively disposed at the central positions on the end faces of a tensioning regulation mechanism and the tensioning support, a knurling adjustment bolt is screwed into the screw hole of the tensioning regulation mechanism and abuts in the blind hole of the tensioning support, thus realizing the tensioning adjustment function on the wire material. The device provided by the invention improves the 3D printing precision and the printing model quality of, and increases the equipment reliability.

Description

technical field [0001] The invention relates to an adjustable wire extrusion monitoring and alarm device, which belongs to the technical field of 3D printing. Background technique [0002] At present, the general wire extrusion device only plays the role of tension wire, and after a period of time, the spring force is insufficient and the wire extrusion becomes loose. In addition, the parallelism between the flange bearing and the stepper motor shaft is insufficient, and the positive pressure of the tension wire decreases. Due to the situation, the quality of the printed model is getting worse and worse over time, and the problems of wire blocking and broken wires during the printing process cannot be handled well, resulting in a lot of waste of consumables for printing failures. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art, provide an adjustable wire extrusion monitoring and alar...

[0002] At present, the general wire extrusion device only plays the role of tension wire, and after a period of time, the spring force is insufficient and the wire extrusion becomes loose. In addition, the parallelism between the flange bearing and the stepper motor shaft is insufficient, and the positive pressure of the tension wire decreases. As a result, the quality of the printed model is getting worse and worse over time, and the problems of wire blocking and broken wires during the printing process cannot be handled well, resulting in more waste of consumables due to printing failures.
