Abstract

The utility model discloses a 3D printer feeding box. The feeding box comprises a casing, a feeding port, a discharging port, a seal ring, a rubber layer, a spring layer and a supporting layer. The casing is in a cavity structure, and powder is arranged in the cavity. The feeding port is arranged at the upper end of the casing, and the discharging port is arranged at the lower end of the casing. The seal ring is fixed at the edge of the discharging port and in a hollow circular structure. The rubber layer is arranged on the outermost side of the seal ring, the spring layer is attached to the inner side of the rubber layer, and the supporting layer is arranged in the hollow circular structure of the seal ring and is attached to the inner side of the spring layer and is formed by a plurality of honeycomb single-edge thin sheets. Each of the honeycomb single-edge thin sheets comprises a plurality of grooves and a plurality of connection portions, any two grooves are fixedly connected at the bottoms of the grooves to form honeycomb holes, and the single-edge thin sheets are elastic. The feeding box has the advantages of being long in service life, not prone to deform, anti-abrasion, capable of preventing powder from leaking easily and performing feeding accurately for the 3D printer and the like.

Description

A kind of 3D chopping machine feed box

Technical field

The utility model relates to a kind of 3D chopping machine feed box.

Background technology

Between feed box lower ending opening edge and 3D chopping machine work top, there is spilling of powder materials in order to prevent in the mechanism that existing 3D chopping machine carries out quantitative feed; thereby ensure the each accurate feeding of feeding to 3D chopping machine; conventionally can be at the lower port edge of feed box fixed seal ring; under the occasion that existing seal ring is had relatively high expectations at some temperature, pressure, rotating speed; its sealing effectiveness is difficult for guarantee, and service life is short, yielding; not wear-resisting, affect operational effect.

Utility model content

The utility model provides a kind of for 3D chopping machine feed box in order to solve prior art problem, and in order to solve the problems of the technologies described above, 3D chopping machine feed box of the present utility model, is characterized in that, comprising:

Housing, its structure that is cavity, places powder in described cavity;

Inlet point, it is arranged on the upper end of described housing;

Discharging opening, it is arranged on the lower end of described housing;

Seal ring, it is fixed on described discharging opening edge, is the loop configuration of hollow;

Rubber layer, its outermost that is described seal ring;

Spring layer, it is close to the inner side of described rubber layer;

Supporting layer, it is arranged in the loop configuration of hollow of described seal ring, be close to described spring layer inner side, formed by the monolateral thin slice of plural pieces honeycomb, the every monolateral thin slice of honeycomb comprises multiple grooves and multiple connecting portion, between any two grooves, by the honeycomb hole that is fixedly connected to form between described channel bottom, described monolateral thin slice has elasticity.

Preferred version: described rubber layer is polytetrafluoroethylene.

Preferred version: described spring layer is that spring leaf is made.

Preferred version: described monolateral thin slice is that elastic sheet metal is made.

A kind of 3D chopping machine feed box long service life that the utility model provides, not yielding, wear-resisting, can realize powder materials and be difficult for spilling, can be to features such as 3D chopping machine accurate feeding.

Detailed description of the invention

Below in conjunction with the drawings and the specific embodiments, the utility model is described in further detail:

As shown in Figure 1, the loop configuration that described seal ring is hollow, rubber layer 1, its outermost that is described seal ring; Spring layer 2, it is close to the inner side of described rubber layer 1, and described spring layer 2 is made for spring leaf; Supporting layer 3, it is arranged in the loop configuration of hollow of described seal ring, be close to described spring layer 2 inner sides, formed by the monolateral thin slice 4 of plural pieces honeycomb, the every monolateral thin slice 4 of honeycomb comprises multiple grooves 5 and multiple connecting portion 6, between any two grooves 5, by being fixedly connected to form honeycomb hole 7 between described channel bottom, described monolateral thin slice has elasticity, can be elastic sheet metal and makes.It is material that rubber layer of the present utility model can be selected polytetrafluoroethylene, and polytetrafluoroethylene can make that the antiseptic power of seal ring is strong, good stability of the dimension, and can bear hurried temperature traverse.

As shown in Figure 2, get a sheet metal, strike out the monolateral thin slice 4 of honeycomb, the monolateral thin slice 4 of honeycomb comprises multiple grooves 5 and multiple connecting portion 6, this groove 5 is shaped as isosceles trapezoid groove, in fact connecting portion 6 is exactly the part that sheet metal is not stamped, and pass through connecting portion 6 transition, or also any two connecting portions 6 carries out transition by groove 5 between any two grooves 5.Foil material select deironing outer, can aluminium, the material such as corrosion-resistant steel, there is the advantages such as lightweight and low price.

As shown in Figure 3, use two monolateral thin slices 4 of honeycomb to dock mutually and fasten, form wall scroll honeycomb structure supporter.Now, multiple honeycomb holes 7 have been formed along monolateral thin slice 4 length directions of honeycomb.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
