Abstract
The utility model relates to a feed throat pipe, particularly relates to a feed throat pipe for an FDM (frequency-division multiplexing)-type 3D printer, and belongs to the field of office supplies. The feed throat pipe is of a hollow structure, the feed throat pipe comprises a feed throat pipe orifice, a feed throat pipe inner wall and a feed thread, wherein the feed thread is arranged on the outer wall of the feed throat pipe and is fixed on a heating aluminum block, and a teflon hose is adhered to the feed throat pipe inner wall or a teflon pattern layer is coated on the feed throat pipe inner wall. According to the feed throat pipe, the teflon hose and the teflon pattern layer are adopted on the inner wall and are used for lubricating the inner wall, so that a friction force between a printed silk and the feed throat pipe inner wall is minimized due to the lubrication effect of the teflon hose, and therefore, a silk outlet is relatively smooth, and a silk blocked symptom uneasily occurs. The feed throat pipe disclosed by the utility model is simple in structure, easy to manufacture, and excellent in application effects.
Description
Technical field
the utility model relates to a kind of charging trunnion, is specifically related to a kind of charging trunnion of FDM type 3D printer, belongs to office appliance field.
Background technology
The selective cladding of filamentary material (Fused Deposition Modeling) rapid prototyping technique is a kind ofly not rely on laser as the moulding energy and by various silk materials, as engineering plastics ABS, polycarbonate etc., heat fused and then heap, long-pending forming method, is called for short FDM.
Table top type FDM three-dimensional printer printing precision is high, and outward appearance is relatively small and exquisite, and installation is easy to carry, most critical, this three-dimensional printer manufacturing cost is lower, for general family can bear, but existing FDM3D printer also fails to solve well while printing the problem of plug wire.
Utility model content
The utility model has designed a kind of charging trunnion, and its object is: the problem of plug wire while printing in order to solve FDM type 3D printer.
The utility model technical solution:
A kind of charging trunnion, described charging trunnion is hollow structure, it is characterized in that: described charging trunnion comprise the feed throat mouth of pipe 1, feed throat inside pipe wall 2 and be arranged on charging trunnion outer wall and for the charging screw thread 3 that is fixed of heating aluminium block, described feed throat inside pipe wall 2 tightens on be sticked Teflon pipe 4 or feed throat inside pipe wall 2 and is coated with Teflon figure layer.
The described feed throat mouth of pipe 1 comprises collar extension and internal orifice, and collar extension diameter is greater than internal orifice diameter, and the mouth of pipe of described internal orifice and Teflon pipe 4 coincide.
the beneficial effects of the utility model:
The utility model has adopted inwall to add Teflon pipe or Teflon figure layer lubricates inwall, utilizes the lubricant effect of Teflon pipe to reduce the frictional force of printing silk material and feed throat inside pipe wall as far as possible, makes wire vent more smooth, and is difficult for occurring plug wire symptom.Of the present utility model simple in structure, easily to make, result of use is splendid.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
below in conjunction with drawings and Examples, the utility model is described in further detail:
Embodiment:
As shown in Figure 1, a kind of charging trunnion, described charging trunnion is hollow structure, described charging trunnion comprise the feed throat mouth of pipe 1, feed throat inside pipe wall 2 and be arranged on charging trunnion outer wall and for the charging screw thread 3 that is fixed of heating aluminium block, described feed throat inside pipe wall 2 tightens on be sticked Teflon pipe 4 or feed throat inside pipe wall 2 and is coated with Teflon figure layer.The described feed throat mouth of pipe 1 comprises collar extension and internal orifice, and collar extension diameter is greater than internal orifice diameter, and the mouth of pipe of described internal orifice and Teflon pipe 4 coincide.
Specific works engineering:
As shown in Figure 1, print silk material from the feed throat mouth of pipe enters, along Teflon pipe, continue transmission, the not viscosity of Teflon pipe and sliding can significantly reduce the frictional force of printing silk material and feed throat inside pipe wall, make wire vent more smooth; In stable condition when the heat resistance of Teflon pipe has also guaranteed to work under continuous high temperature state simultaneously, the mar proof of Teflon pipe has also guaranteed the smooth degree of rear feeding trunnion inwall that works long hours simultaneously, so improve, makes charging trunnion be difficult for occurring plug wire symptom.Thereby guaranteed the service life of three-dimensional printer.
To sum up, the utility model accomplishes the end in view.
