Technical Field

[0001] This utility model relates to the field of hose production and processing technology, and in particular to a biomedical hose production feeding device. Background Technology

[0002] Biomedical tubing is a type of flexible tubular device used in the medical field. It is usually made of biocompatible materials such as silicone rubber, polyurethane, and polytetrafluoroethylene. It has core characteristics such as non-toxicity, resistance to body fluid corrosion, and good flexibility. It can be designed with different inner diameters, lengths, and structures according to clinical needs. It is widely used in human fluid delivery, gas exchange, and interventional diagnosis and treatment scenarios, such as infusion tubing, urinary catheters, cardiovascular interventional catheters, and breathing circuit tubing.

[0003] In the production process of biomedical tubing, screw conveyors are often used to transport the raw materials for the tubing. In daily work, it has been found that in the process of feeding existing feeding devices (screw conveyors), due to the large amount of raw materials accumulating in the hopper and then being gradually transported by the screw structure, some raw material particles tend to accumulate at the discharge port. This not only causes discharge blockage but also leads to unstable discharge, affecting subsequent production. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology where a large amount of raw materials accumulate in the hopper and are gradually conveyed by a spiral structure, and some raw material particles tend to accumulate at the discharge port, which not only causes discharge blockage but also leads to unstable discharge and affects subsequent production. Therefore, this invention proposes a feeding device for the production of biomedical tubing.

Each set of rotating sleeves has two sleeves, and a stirring rod is slidably connected to the inner wall of each set of rotating sleeves. The machine body is equipped with a transmission assembly for controlling the rotation of the two sets of rotating sleeves to drive the stirring rods to rotate and stir the raw materials via the rotation of a screw rod. The machine body is also equipped with a pushing assembly for controlling the back-and-forth movement of the stirring rods within the rotating sleeves. A mating assembly is provided between the rotating sleeves and the feed hopper for striking the feed hopper. Through the above components, during use, the motor drives the screw rod to rotate, and during the feeding process, the screw rod can cooperate with the transmission assembly to drive the two sets of rotating sleeves to rotate. The rotating sleeves can drive the stirring rods to rotate synchronously, stirring the raw materials and reducing blockage. At the same time, the pushing assembly can drive the stirring rods to move back and forth within the rotating sleeves, further reducing the phenomenon of raw material blockage.

Two push rods are rotatably connected to the surface of the connecting block. The other end of the push rod is inserted into a rotating sleeve and fixedly connected to the surface of the stirring rod. Through the above components, when the stirring rod rotates, it can drive the push rod to rotate on the connecting block. When the cylinder can drive the connecting block to move and reset, the push rod can drive the stirring rod to move and reset.

The two ends of the spring are fixedly connected to the surfaces of the fixed rods and the frame, respectively. An extrusion wheel is fixedly connected to the surface of the rotating sleeve. Through the above components, the rotating sleeve rotates, which drives the extrusion wheel to rotate. The extrusion wheel extrudes the frame, and the frame can drive the striking rods to move. When the extrusion wheel loses its extrusion on the frame, the spring drives the frame and the striking rods to reset. The striking rods strike the feed hopper to assist in material feeding.

The stirring rod can continuously stir the raw materials in the feed hopper, and at the same time, the pushing component can drive the rotating stirring rod to move back and forth, which can create a more comprehensive disturbance to the raw materials in the feed hopper, so that the raw material particles flow more evenly to the discharge port and reduce the phenomenon of clogging at the discharge port.

[0013] 2. In this utility model, by setting a matching component, the rotating sleeve drives the extrusion wheel to periodically extrude the frame, and then the spring resets to realize the repeated knocking of the tapping rod on the feed hopper. The rubber ball not only reduces the damage to the feed hopper during knocking, but also allows the raw materials attached to the hopper wall to fall off through vibration, further assisting the feeding.
