Description
Technical Field
The utility model belongs to the technical field of 3D printing apparatus, concretely relates to 3D prints flat belt dustproof construction of S type.
Background
3D printing is a rapid prototyping technique. Based on the digital model file, the hierarchical data of the part is generated by computer aided design and is led into a forming device, and the powder material is sintered layer by layer through a laser so as to realize the forming of the part. In the 3D printing process, powder easily enters a powder laying driving mechanism (such as a guide rail sliding block and a bearing), so that the abrasion of the powder laying driving mechanism is aggravated, the service life is shortened, and the dustproof sealing must be carried out on a printing area and a driving area.
At present, the dust seal of powder actuating mechanism is spread to 3D printer mainly adopts the sealed mode of flat belt, and both sides paste simultaneously in the inboard or the outside of sealed panel beating about the flat belt, always have one side not tight with the laminating of sealed panel beating, and the powder easily gets into the drive region from this breach, leads to actuating mechanism motion jamming, and wearing and tearing are serious.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a 3D prints flat belt dustproof construction of S type has solved the poor problem of current sealing mechanism seal effect.
The utility model adopts the technical proposal that: the utility model provides a 3D prints flat belt dustproof construction of S type, includes the flat belt, and the outside, interior both sides of flat belt direction of advance have set gradually upper seal panel beating and lower seal panel beating, and the lower limb and the laminating of flat belt upper edge of upper seal panel beating, the upper limb and the laminating of flat belt lower limb of lower seal panel beating.
The utility model is also characterized in that,
and sealing rubber strips are adhered to one side, close to the flat belt, of the lower edge of the upper sealing metal plate and one side, close to the flat belt, of the upper edge of the lower sealing metal plate.
The inner sides of the front end and the rear end of the flat belt are respectively sleeved with a longitudinal rotating shaft.
The center of the rotating shaft is provided with an annular guide groove along the circumferential direction, and the center of the inner wall of the flat belt is provided with a guide strip matched with the guide groove along the length direction.
The upper end and the lower end of the rotating shaft are connected with a rotating shaft seat together, and one side of the rotating shaft seat, which is far away from the flat belt, is connected with a pull rod.
The utility model has the advantages that: the utility model relates to a dustproof structure of a 3D printing S-shaped flat belt, which has simple structure, good stability and low cost; the upper side and the lower side of the sealing ring are of S-shaped structures, so that the sealing effect is improved; the problems of movement clamping stagnation, serious flat belt abrasion and shortened service life of a driving part caused by the fact that powder easily enters a driving area in the 3D printing process are solved.
Drawings
Fig. 1 is a schematic structural view of a 3D printing S-shaped flat belt dustproof structure of the present invention;
fig. 2 is the utility model relates to a 3D prints S type flat belt dustproof construction' S cross-sectional view.
In the figure, 1, a rotating shaft, 2, an upper sealing metal plate, 3, a flat belt, 4, a lower sealing metal plate, 5, a rotating shaft seat, 6, a pull rod and 7, sealing rubber strips.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The utility model provides a 3D prints flat belt dustproof construction of S type, as shown in figure 1 and figure 2, by pivot 1, flat belt 3, go up sealed panel beating 2, down sealed panel beating 4, joint strip 7 etc. constitute.
As shown in figure 1, two rotating shaft seats 5 are arranged left and right, a rotating shaft 1 is arranged on each rotating shaft seat 5 to support a flat belt 3, the flat belts 3 can move along with the rotation of the rotating shafts 1, a guide groove is arranged in the middle of each rotating shaft 1, and a guide strip is arranged in the middle of each flat belt 3, so that the flat belts 3 can be prevented from deviating in the moving process.
As shown in figure 2, the belt side is pasted with sealing rubber strip 7 below the upper seal metal plate 2, the belt side is pasted with sealing rubber strip 7 above the lower seal metal plate 4, and sealing rubber strip 7 adopts wear-resistant material, and the surface is smooth, can reduce the wearing and tearing of flat belt.
As shown in fig. 1 and 2, the upper sealing metal plate 2 is arranged on the outer side of the flat belt 3, the sealing rubber strip 7 adhered to the upper sealing metal plate 2 is tightly attached to the outer surface of the flat belt 3, the lower sealing metal plate 4 is arranged on the inner side of the flat belt 3, and the sealing rubber strip 7 adhered to the lower sealing metal plate 4 is tightly attached to the inner surface of the flat belt 3.
As shown in fig. 1, a pull rod 6 is installed outside the rotating shaft seat 5, and the rotating shaft seat 5 can be pulled to drive the rotating shaft 1 to tension the flat belt 3, so that the flat belt 3 is tightly attached to the sealing rubber strip 7 to prevent powder leakage.
The utility model relates to a 3D prints flat belt dustproof construction theory of operation of S type as follows:
when powder in a printing area (the left part of a figure 2) enters a driving area (the right part of the figure 2) through a gap between an upper sealing metal plate 2, a lower sealing metal plate 4, a sealing rubber strip 7 and a flat belt 3, the powder firstly passes through the lower surface of the upper sealing metal plate 2 and then passes through the upper surface of the flat belt 3 from the upper edge seam; from lower seam, need pass through flat belt 3 lower surface earlier, pass through the upper surface of lower sealed panel beating 4 again, no matter from last seam or lower seam, all need around an S type route.
Through the mode, the dustproof structure for the 3D printing S-shaped flat belt has the advantages of simple structure, good stability and low cost; the upper side and the lower side of the sealing ring are of S-shaped structures, so that the sealing effect is improved; the problems of movement clamping stagnation, serious flat belt abrasion and shortened service life of a driving part caused by the fact that powder easily enters a driving area in the 3D printing process are solved.
