Description

Technical Field

[0001] The utility model relates to the field of 3D printing equipment, in particular to a 3D printing wire management mechanism. Background Art

[0002] As is known, the most widely used 3D printer molding technology on the market is the FDM fused deposition modeling technology 3D printer, which has the highest market share. This type of 3D printer uses different raw materials to make filamentary materials as the basic printing materials of the 3D printer according to different working conditions and characteristics. The market standard of filament materials is mostly 1Kg-10KG per tray. The weight of the material used to meet the needs of models of different sizes and weights is also different. At the same time, the installation position of the tray designed by the 3D printer is also different;

[0003] If the material tray of a frame-type 3D printer is on the outside of the bottom frame, the filament may collapse above the printer when it is guided to the nozzle, affecting the normal operation of the nozzle and the platform. The existing solution is to balance the rigidity and flexibility of the material tube so as not to affect the adjustment and movement of the filament guide tube following the nozzle, and select a suitable material tube with less obvious collapse. However, this increases the cost of material selection, and it also needs to be replaced when changing materials or when the performance deteriorates after long-term use, which is very inconvenient. Utility Model Content

[0004] In order to overcome the deficiencies in the background technology and solve the existing technical problems, the utility model discloses a 3D printing wire management mechanism, which does not affect the flexible movement of the nozzle and can provide long-term and effective support for the material line.

[0005] In order to achieve the above-mentioned invention object, the utility model adopts the following technical solutions:

[0006] A 3D printing cable management mechanism comprises a support rod and a cable sleeve with elasticity and used to cover a material tube above a printer frame, wherein the bottom end of the support rod is installed on the printer frame, and the top end of the support rod is universally connected to the outer wall of the cable sleeve; the sleeve wall of the cable sleeve is provided with an insertion slot passing through the two ends of the cable sleeve, and the edges of the two sleeve walls of the cable sleeve corresponding to the insertion slot on both sides are turned outward to form a flange portion.

[0007] Furthermore, a universally connected ball head and a ball head cover are respectively fixed to the top end of the support rod and the outer wall of the middle sleeve body of the cable sleeve.

[0008] Furthermore, both ends of the cable tie sleeve are provided with annular grooves along the circumference of the cable tie sleeve.

[0009] Furthermore, the cable tie sleeve walls corresponding to the outer sides of the two flanged portions are provided with through grooves along the length direction of the flanged portions.

[0010] Furthermore, the material tube is bundled with cables in parallel, and the cable sheath is sleeved outside the cables.

[0011] Furthermore, a steel wire is passed through the cable.

[0012] Furthermore, a flexible wire trough is fixed on the printer frame at the feeding end of the material tube.

[0013] Furthermore, a suction cup or a clamp is fixed to the bottom end of the support rod.

[0014] Due to the adoption of the above-mentioned technical solution, the utility model has the following beneficial effects:

[0015] The 3D printing wire management mechanism disclosed by the utility model holds the material tube by a wire harness and supports the material tube by a support rod, thereby preventing the wire tube from collapsing and affecting the operation of the nozzle and the platform; the support rod and the wire harness are universally connected, which can ensure that the consumable material tube can be turned and adjusted with the movement of the nozzle, preventing winding and clogging of consumables. Compared with the prior art, the utility model effectively solves the problem of consumable material tube collapse at a low cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solution of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" and the like indicating directions or positional relationships, they are only corresponding to the drawings of the present invention, for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific direction: Embodiment 1:

[0020] Combined with Figure 1 and 2The 3D printing cable management mechanism includes a support rod 3 and a cable sleeve 2 which is elastic and is used to fit the material tube 1 above the printer frame 4. The elastic cable sleeve 2 is convenient for deformation placement and tightening of the material tube 1. The bottom end of the support rod 3 is fixed to the printer frame 4. The top end of the support rod 3 is universally connected to the outer wall of the cable sleeve 2 to ensure that the cable sleeve 2 can be horizontally rotated relative to the support rod 3 and flipped up and down at both ends. There are many conventional universal connection structures, such as a cross-axis universal joint or a ball head universal structure, etc. According to the needs, the present application can fix a universally connected ball head 6 and a ball head sleeve 7 at the top end of the support rod 3 and the outer wall of the middle sleeve of the cable sleeve 2, respectively, which is low in cost, easy to assemble, and reduces the connection shaking of the cable sleeve 2.

[0021] The sleeve wall of the cable sleeve 2 is provided with an insertion slot 201 that passes through the two ends of the cable sleeve 2. The edges of the two sleeve walls of the cable sleeve 2 corresponding to the insertion slot 201 on both sides are turned outward to form a flange portion 202. The material tube 1 of the consumable material can be inserted into the cable sleeve 2 from the insertion slot 201, and the expanded flange portion 202 has the effect of facilitating the insertion; as needed, both ends of the cable sleeve 2 are provided with an annular groove 203 along the circumference of the cable sleeve 2. In order to prevent the material tube 1 from detaching, an annular cable tie can also be provided in the annular groove 203 for fastening; in addition, the sleeve walls of the cable sleeve 2 corresponding to the outer sides of the two flange portions 202 are provided with a through groove 204 along the length direction of the flange portion 202. In order to increase the structural strength, the sleeve wall of the cable sleeve 2 is thicker. The provision of the through groove 204 can not only reduce consumables, but also facilitate the elastic expansion of the two flange portions 202, which is more conducive to the insertion of the material tube 1.

[0022] To implement the 3D printing wire management mechanism of the utility model, it is only necessary to fix the lower end of the support rod 3 at the middle position of the printer frame 4 corresponding to the maximum extension of the material tube 1, and then insert the material tube 1 into the cable sleeve 2 through the insertion slot 201; in order to prevent the feed end of the material tube 1 from being excessively bent, a flexible wire trough 5 can be fixed at the printer frame 4 corresponding to the feed end of the material tube 1, and the feed end of the material tube 1 can be appropriately bent and supported. Embodiment 2:

[0023] The difference from the first embodiment is that the material tube 1 is designed to be bundled with cables in parallel, and the cable sleeve 2 is sleeved outside the cable to reduce the direct clamping of the material tube 1. At the same time, the material tube 1 and the signal cable are parallel, which can also prevent collapse. According to needs, steel wires are passed through the cables to enhance the overall supporting effect. Embodiment three:

[0024] The difference from the first embodiment is that a suction cup or a clamp is fixed to the bottom of the support rod 3, which can be quickly sucked and clamped into the frame, making it easy to disassemble and assemble, and the installation position of the support rod 3 can be adjusted according to the needs of different machine models and material pipes 1.
