[0002] In peritoneal dialysis treatment, the dialysate bag needs to be connected to the patient's abdominal cavity through the dialyzer to store and transport the dialysate. It is widely used in hospitals, clinics and other places. It mainly consists of two parts: the bag body and the soft catheter.

[0003] In the prior art, dialysis fluid bags are manufactured by separately manufacturing the bag body and the flexible catheter, which are then heat-pressed and sealed together. However, when assembling the bag body and the flexible catheter, the double-layer bag body needs to be opened manually before the intubation operation is performed, which not only affects production efficiency but also leads to high manual production costs.

[0004] To this end, we propose a conveying structure for a peritoneal dialysis fluid bag making machine tooling to solve the above problems. Utility Model Content

Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-4 A conveying structure of a peritoneal dialysis fluid bag making machine tooling includes a discharge rack 1, a tensioning roller 2, a support platform 1 3, and a support platform 2 4 arranged in sequence along the conveying line direction. Guide rollers 6 are symmetrically installed at both ends of the support platform 1 3 for rotation. A traction roller 5 is rotatably installed at the output end of the support platform 2 4, and a motor 3 9 is installed on the side of the support platform 2 4 to drive the traction roller 5 to rotate. A material separation roller 7 is also rotatably installed on the support platform 2 4. The double-layer film material is installed on the discharge rack 1. After the double-layer film material on the discharge rack 1 is rotated and released, it first passes under the tensioning roller 2. Then it is spread flat on the support platform 3 and the guide roller 6, and is divided into two layers, upper and lower, when passing through the dividing roller 7. Then, the dividing roller 7 forms a tube insertion space between the two layers of membrane material, which is convenient for the placement of the soft catheter and the assembly of the membrane material. The assembled double-layer membrane material and the soft catheter are transported on the support platform 4. Under the action of the gravity of the membrane material itself, when it is farther and farther away from the dividing roller 7, the space between the double-layer membrane material gradually closes, thereby fitting together with the soft catheter to achieve re-closing. When the traction roller 5 rotates, it can assist in the transmission of the re-closed double-layer membrane material and the soft catheter.

[0025] Considering that in order to facilitate the replacement of the double-layer film roll, the unwinding rack 1 is provided, which includes a fixed rack 11 and a movable rack 12. Among them, the fixed rack 11 is an L-shaped structure, and the opposite surfaces of the fixed rack 11 and the movable rack 12 are symmetrically rotated and installed with end plates 13. The end plates 13 are used to clamp at both ends of the reel of the double-layer film roll, thereby clamping and fixing the double-layer film roll. At the same time, a motor 14 for driving the end plates 13 to rotate is also installed on the fixed rack 11, which is convenient for controlling the unwinding of the double-layer film roll. A screw 15 and a polished rod 16 parallel to each other are installed under the fixed rack 11. The two ends of the screw 15 are rotatably connected to the fixed frame 11, and one end of the screw 15 passes through the side of the fixed frame 11 and is installed with a second motor 17. The screw 15 and the polished rod 16 both pass through the bottom of the movable frame 12, and the screw 15 and the movable frame 12 are threadedly connected, so that when the motor 2 17 drives the screw 15 to rotate, the movable frame 12 can move axially along the polished rod 16 and the screw 15 under the limiting action of the polished rod 16, thereby adjusting the distance between the end plate 13 between the fixed frame 11 and the movable frame 12, so as to facilitate the replacement of the double-layer film material roll.

[0026] Furthermore, an insert block 131 is provided on the opposite side of the end plate 13, and the insert block 131 adopts a non-cylindrical structure, so that when the end plate 13 clamps the double-layer film roll, the insert block 131 can be inserted into the inner groove of the roll drum of the double-layer film roll, thereby effectively preventing the double-layer film roll from slipping when unwinding.

[0027] In order to facilitate the adjustment of the tension during film material transportation, a bracket 21 is installed under the tensioning roller 2, and the tensioning roller 2 is rotatably connected to the bracket 21. A vertically lifting telescopic member 8 is installed under the bracket 21. The telescopic member 8 can be but is not limited to one of a cylinder, a hydraulic cylinder, and an electric push rod. The telescopic member 8 drives the tensioning roller 2 to rise and fall, so as to adjust the tension during film material discharge.

[0028] In order to improve the traction effect of the traction roller 5, a plurality of anti-slip strips 51 are provided on the outer surface of the traction roller 5 along the circumferential direction, and the anti-slip strips 51 are parallel to the axial direction of the traction roller 5. The anti-slip strips 51 are made of silicone material, so that when they come into contact with the surface of the film material, the traction effect on the film material is enhanced to prevent the film material from slipping with the traction roller 5.

[0029] In order to reduce the friction damage of the film material during transportation, the horizontal plane height of the upper edge of the guide roller 6 is set to be 1-2mm higher than the upper surface height of the support platform 3, thereby reducing the direct friction contact between the film material and the upper surface of the support platform 3 during transportation. Similarly, the horizontal plane height of the upper edge of the guide roller 6 is set to be equal to the horizontal plane height of the axis of the dividing roller 7, and the horizontal plane height of the lower edge of the dividing roller 7 is 4-5mm higher than the upper surface height of the support platform 2 4, thereby reducing the contact area of ​​the film material on the upper surface of the support platform 2 4, thereby reducing friction damage.

[0030] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0031] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
