Detailed Description

The present invention will be described with reference to specific examples.

Fig. 1 is a front view of a stent graft of the present invention, and fig. 2 is a structural view of the stent graft of the present invention, and as shown in fig. 1 and 2, the stent graft of the present invention comprises: the film laminating machine comprises a conveying frame 1, a bridge type film laminating frame 3 erected above the conveying frame 1, a feeding roller 4 installed on the film laminating frame 3, and film laminating paper 5 wound on the feeding roller 4. From last down including in proper order on the lateral wall of tectorial membrane frame 3: a plurality of first brackets 31, a plurality of second brackets 32, a plurality of third brackets 33 and a plurality of fourth brackets 34 which are all symmetrically arranged.

The feeding roller 4 comprises a third roller 43 arranged on the third bracket 33, a fourth roller 44 and a fifth roller 45 arranged on the fourth bracket 34, fig. 4 is a partial view A of fig. 1, as shown in fig. 4, the centers of the fourth roller 44 and the fifth roller 45 are equal in height, the radius of the fifth roller 45 is larger than that of the fourth roller 44, the coated paper 5 is sequentially wound on the outer sides of the fourth roller 44 and the fifth roller 45 according to the paper feeding sequence, the included angle formed by the coated paper 5 and the horizontal plane is β, and the value range of β is greater than or equal to 12 degrees and less than or equal to β degrees and less than or equal to 30 degrees.

The device utilizes the film covering frame 3 to realize the whole film covering process of the film covering paper 5, the slurry 22 moves towards the film covering frame 3 along the conveying belt 13, the slurry 22 is gradually and uniformly spread in the process, when the film covering is received, the slurry 22 is pressed by the film covering paper 5 to be filled under the film covering paper 5, and no empty slurry exists, the fourth roller 44 and the fifth roller 45 are arranged for final film covering of the paper surface, an angle β is arranged, the slurry 22 is gradually pressed and flattened along with the movement of the conveying belt 13, and the film covering paper 5 is covered, the slurry can be uniformly distributed under the paper material, the limits of 12 degrees and 30 degrees are the best ranges obtained by debugging according to the processing experience, the excessive upwelling of the slurry 22 and foaming of the paper surface can be prevented, or enough angle space can be ensured, and the upwelling of the slurry 22 can be contained.

An angle formed by the coated paper 5 wound around the outer side of the third roller 33 is alpha, and the range of the angle alpha is 60 degrees to 90 degrees. The angle is set to flatten the coated paper and play a role in adjusting the tension degree of the coated paper. Alpha is larger than 90 degrees, the tension of the coated paper 5 is insufficient, the action of the third roller 43 is reduced, and the coated paper 5 can be folded, so that the coated paper cannot be smoothly coated during coating. Less than 60 degrees, the coated paper 5 is excessively tensioned and has too large pulling force, so that the coated paper 5 cannot be coated on the surface of the slurry 22 in time, and sometimes the coated paper is pulled back. This is a range of angles suitable for industrial processing, both empirically and by tuning.

The feed roller 4 includes: a first roller 41 installed on the first bracket 31, and a second roller 42 installed on the second bracket 32. The first roller 41 and the second roller 42 have the same diameter, and the centers thereof are located on the same vertical line. The coated paper 5 is wound on the side of the first roller 41 and the second roller 42 close to the coating frame 3, and the coated paper 5 is perpendicular to the horizontal plane. This section's setting is in order to let laminating paper 5 can from the top down transition, and the tensioning degree when making the below roller of transmission can not influence laminating paper 5 and get into. The second roller 42 also performs the transition to the third roller 43, which adjusts the tension.

The first stent 31, the third stent 33 and the fourth stent 34 are all arranged perpendicular to the tectorial membrane frame 3, and the second stent 32 is arranged perpendicular to the third stent 33. Set up like this, be convenient for install the running roller that accords with the condition.

A slurry machine 2 is fixed on the conveying frame 1, and a nozzle 21 is arranged on the slurry machine 2. A plurality of conveying rollers 12 are installed on the conveying frame 1, and conveying belts 13 are connected to the conveying rollers 12 in a rolling mode. The nozzle 21 is located above the conveyor belt 13, proximate to the conveyor belt 13. This arrangement avoids splattering of the slurry 22 and maximizes the width distribution of the slurry 22.

Along the conveying direction of the conveyor belt 13, the pulp machine 2, the film frame 3 and the leveling bridge 14 are arranged in sequence. Fig. 3 is a structural view of a leveling bridge, and as shown in fig. 3, the leveling bridge 14 is erected on the conveying frame 1, and the leveling bridge 14 is positioned right above the laminating paper 5. The height from the bridge bottom surface of the leveling bridge 14 to the top surface of the conveyor belt 13 is a standard height determined by the processing. The surface of the coated paper 5 is flattened by using the flattening bridge 14, so that the flattening effect is achieved.

A paper outlet machine 51 is connected above the film covering frame 3. A control system 6 is connected above the paper outlet machine 51.

It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
