3D printer material tray fixing device

Abstract

The invention provides a 3D printer material tray fixing device. According to the device, a material tray is inserted and clamped in a material frame mounting hole in the right side face of a rack, and the material tray fixing device solves the problem that empty printing is caused by too large material tray hanging friction force and wire rod coiling friction force before a printing wire rod enters a feeding device. The invention also provides a vertical material tray fixing device. The material tray fixing device is mounted on the rack upper end edge at the vertex angle of the upper plane of the rack, a material rod of the vertical material tray fixing device can be matched with a material tray assembly of the above material tray fixing device through simple structural changes, a smoother material conveying manner can be provided, and meanwhile the range of wire rods of printing capable of being supported by a 3D printer can be expanded. The design of appearance modeling of lotus seedpods and lotus flowers is adopted, the expected protection function of a motion device is guaranteed, and meanwhile the product quality and grade of the device are greatly improved.

Description

technical field [0001] The invention relates to the technical field of special fixtures, in particular to a 3D printer tray fixing device. Background technique [0002] Raise3D's rectangular box-type desktop 3D printer adopts the fusion filament manufacturing technology to stack melted thermoplastic composite wires, such as ABS, PLA, and TPU, into a 3D solid model. It is different from traditional mechanical processing and abrasive casting. It can directly use CAD graphic data to add material to manufacture molded solid parts. It is easy to obtain a balance between structural complexity and light weight in parts manufacturing. Its manufacturing speed is high and its precision is high. , low price and high ease of use. [0003] Patent CN206544317U discloses a desktop-level 3D printer, which describes a series of models, such as figure 1 , the material tray 7 used to store the printing wire 5 is directly suspended on the material rack 9; The feed conduit 6 on the upper righ...

AI Technical Summary

Problems solved by technology

[0004] It has been found through actual use that during the transmission process of the wire 5, the friction between the feed conduit 6 and the wire 5 is relatively large; and the configuration of the wire transmission mechanism in which the tray 7 is attached to the material rack 9 by gravity increases the speed of the wire passing through the feed conduit 6. The resistance; especially the full new tray, will also increase the effective continuous delivery of the wire because of the random winding of the wire 5 on the tray 6; so that the hot-melt wire at the outlet of the nozzle cannot be supplied enough, thus affecting Buildup of fully formed parts on the build platform 2, resulting in a so-called "empty print"
