DETAILED DESCRIPTION

[0014] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0015] See attached Figure 1 With attached Figure 2 A dialyzer tubing curling device includes a curling rotary disk 1, a tube clamp 2, and a tube winding rod 10, wherein the curling rotary disk 1 is driven by a servo motor, the tube clamp 2 is arranged on the curling rotary disk 1 and is used to clamp the front end of the dialyzer main line, the tube clamp 2 is driven by a turntable tube clamping cylinder 2, and the turntable tube clamping cylinder 2 is arranged below the curling rotary disk 1; the tube winding rod 10 adopts three, and three tube winding rods 10 and a tube loosening rod 9 are evenly distributed around the center of the curling rotary disk 1 for winding the dialyzer tubing. On the curling rotary disk 1, the three tube winding rods 10 and the tube loosening rod 9 are used as the four vertices of a square. When the dialyzer tubing is curled, the tube clamp 2 and the turntable tube clamp cylinder 2 are used to clamp one end of the tubing to ensure that the tubing does not fall off during the curling process. The curling rotary turntable 1 automatically curls the tubing according to the predetermined curling speed and number of turns under the action of the servo motor.

[0016] Furthermore, the location of the tube loosening rod 9 is provided with an elongated open slot 3. The vertically arranged tube loosening rod 9 passes through the elongated open slot 3 and is drivingly connected to the turntable tube loosening cylinder below the winding rotary disk 1. The tube loosening rod 9 is adjustable along the elongated open slot 3 under the drive of the turntable tube loosening cylinder 3. When the winding is completed, the turntable tube loosening cylinder 3 drives the tube loosening rod 9 to move within the elongated open slot 3 and approach the center of the winding rotary disk 1, making it convenient for manual labor to easily remove the wound pipeline from the tube winding rod 10.

[0017] A pipeline clamping auxiliary mechanism is provided on one side of the winding rotating turntable 1. The pipeline clamping auxiliary mechanism is actuated to clamp the rear end pipeline to ensure that the dialyzer pipeline is in a straightened state. The pipeline clamping auxiliary mechanism includes a side pressure plate cylinder, an upper pressure plate cylinder, and a tail clamping cylinder. The side pressure plate cylinder is drivably connected to the side pressure plate 5 and the upper pressure plate cylinder is drivably connected to the upper pressure plate 7 to clamp the dialyzer side branch pipeline. The tail clamping cylinder is drivably connected to the tail pressure plate 8 to clamp the rear end of the dialyzer main pipeline.

[0018] The rear side of the tail pressure plate 8 is provided with a clamping part 4, and the clamping part 4 is connected to the pipeline curling upward auxiliary cylinder and drives it to rise slowly. The part of the dialyzer pipeline to be curled rises slowly with the rotation of the curling rotating turntable 1, so that the pipeline can be wound in layers during the curling process, ensuring that the various accessories of the pipeline do not affect the curling effect.

[0019] In the present invention, the control air circuits of all cylinders are connected to the external pneumatic control components through the air slip ring 6 .

[0020] Working process of this utility model:

[0021] The tube feeding mechanism sends the tube to the curling rotary disc 1, and the rotary disc tube clamping cylinder drives the tube clamping fixture 2 to clamp one end of the dialyzer tube. Driven by the servo motor, the curling rotary disc 1 rotates at a predetermined speed and position and rotates a certain angle. After the dialyzer tube water stop clamp and other large accessories pass through the arc-shaped curling channel 11 formed between the upper pressure plate 7 and the side pressure plate 5, the side pressure plate cylinder and the upper pressure plate cylinder are actuated to press the tube on the curling channel 11, ensuring that the dialyzer tube is always in the Straightened state; after the main line is curled, the tail pressing cylinder is activated. At this time, if the tail pressure plate 8 does not press the tail end pipeline, the tail end pipeline will be in a free state driven by the servo motor, and the consistency and stability of the curling effect cannot be guaranteed; when the curling is completed, the pipeline clamping auxiliary mechanism returns to its original position, and the turntable clamping cylinder and the turntable loosening cylinder are opened at the same time, so that the dialyzer pipeline can be easily removed from the curling rotating turntable 1 by manual or automatic tube removal mechanism after curling.
