Description

Technical Field

[0001] This utility model relates to the field of medical soft catheter manufacturing, and specifically to a device for precision cutting of medical soft catheters. Background Technology

[0002] In the field of medical catheter manufacturing, extremely high precision and quality are required for catheter cutting. Traditional medical catheter cutting devices have several problems. For example, they cannot effectively clean and dry the catheters before cutting, resulting in residual moisture and impurities on the catheter surface, affecting subsequent cutting precision and product quality. Furthermore, traditional devices use conventional pushing mechanisms to move the cut catheters to the collection platform, which is slow and inefficient. Therefore, to overcome the shortcomings of existing technologies, a simple, efficient, and dryable device for precision cutting of medical catheters needs to be designed. Utility Model Content

[0003] This invention addresses the problems of existing technologies by providing a device for precisely cutting medical soft catheters.

[0004] The objective of this utility model can be achieved through the following technical solution: A device for precision cutting of medical flexible catheters includes a water-cooled box, a water blowing assembly, a cutting assembly, and a blowpipe assembly arranged sequentially. The water-cooled box is equipped with a guide wheel for the flexible catheter. The water blowing assembly is located at the discharge end of the water-cooled box. The water blowing assembly includes a water blowing plate, an air bladder, and a first compressed air assembly. The water blowing plate has a channel in the middle and air passages are evenly distributed on the water blowing plate. The tail end of the air passage is connected to the air bladder. The front end of the air passage is connected to the channel and the air passage is inclined towards the center of the channel. The air inlet direction of the air passage is opposite to the moving direction of the flexible catheter. The air bladder is connected to the first compressed air assembly through a pipe. The cutting assembly is equipped with a power wheel and a cutting blade for driving the flexible catheter forward. The blowpipe assembly includes a conveyor belt, a catheter, a second compressed air assembly, and a collection platform. The conveyor belt is located on the right side of the cutting assembly. The catheter is arranged parallel to one side of the conveyor belt and has evenly distributed air holes. One end of the catheter is connected to the second compressed air assembly through a pipe. The collection platform is arranged parallel to the other side of the conveyor belt.

[0005] In a further improvement, the water-cooled box is provided with a water tank at the bottom, and a water pump is provided in the water tank. The water-cooled box includes an inlet chamber and an outlet chamber. The outlet chamber is located at both ends of the inlet chamber. The liquid level in the outlet chamber is lower than that in the inlet chamber. The outlet chamber is connected to the water tank through an inlet pipe. The inlet chamber is connected to the output end of the water pump through an outlet pipe.

[0006] In a further improvement, the blowing plate is evenly distributed with eight rows of air channels, and each row of air channels has four channels.

[0007] As a further improvement, an inclined conveyor plate is provided between the collection platform and the conveyor belt.

[0008] In a further improvement, a guide frame is provided between the water blowing assembly and the cutting assembly, and two sets of guide rollers are symmetrically arranged on the guide frame.

[0009] In a further improvement, the guide wheels are arranged sequentially and spaced vertically within the water-cooled box.

[0010] Compared with existing technologies, the advantages of this utility model for precision cutting of medical flexible catheters are as follows:

[0011] The flexible conduit is cooled by passing through a water-cooling box. After exiting the water-cooling box, it enters the water blowing assembly. The air passage of the water blowing plate is connected to the air bag. The compressed air assembly supplies air to the air bag. The air is blown out from the channel through the air passage. Since the air passage is inclined towards the center of the channel and the air intake direction is opposite to the moving direction of the flexible conduit, the water droplets on the surface of the flexible conduit can be effectively blown off, thus drying the flexible conduit and ensuring the quality of subsequent products.

[0012] The flexible conduit then enters the cutting assembly, where a power wheel drives it forward, and the cutting blade cuts it. The cut conduit falls onto the conveyor belt, where a compressed air assembly supplies air to the conduit. The airflow through the vents quickly blows the conduit towards the collection platform, improving production efficiency. Attached Figure Description

[0021] The following is a description of the embodiments and appendices. Figures 1-5 The technical solution of this utility model will be further described below.

[0022] Example 1

[0023] A device for precision cutting of medical flexible catheters includes a water-cooled box 1, a water blowing assembly 2, a cutting assembly 4, and a blow tube assembly 5 arranged sequentially. The water-cooled box 1 contains guide wheels 17 for the flexible catheter. The water blowing assembly 2 is located at the outlet end of the water-cooled box 1. The water blowing assembly 2 includes a water blowing plate 21, an air bag 22, and a compressed air assembly 23. The water blowing plate 21 has a channel 211 in the middle, and air passages 212 are evenly distributed on the water blowing plate 21. The tail end of each air passage 212 is connected to the air bag 22, and the front end of each air passage 212 is connected to the channel 211 and is inclined towards the center of the channel 211. The air intake direction is opposite to the moving direction of the flexible conduit. The airbag 22 is connected to the compressed air assembly 23 through a pipe. The cutting assembly 4 is equipped with a power wheel 41 and a cutting blade 42 that drive the flexible conduit forward. The blowing assembly 5 includes a conveyor belt 51, a conduit 52, a compressed air assembly 53, and a collection platform 54. The conveyor belt 51 is located on the right side of the cutting assembly 4. The conduit 52 is arranged parallel to one side of the conveyor belt 51. Air holes 521 are evenly distributed on the conduit 52. One end of the conduit 52 is connected to the compressed air assembly 53 through a pipe. The collection platform 54 is arranged parallel to the other side of the conveyor belt 51.

[0024] like Figures 1-5 As shown, the working principle of this utility model is as follows: The flexible conduit is cooled sequentially by the water-cooling box 1. After exiting the water-cooling box 1, it enters the water blowing assembly 2. The air passage 212 of the water blowing plate 21 is connected to the air bag 22. The compressed air assembly 23 supplies air to the air bag 22. The air is blown out from the channel 211 through the air passage 212. Since the air passage 212 is inclined towards the center of the channel 211 and the air intake direction is opposite to the moving direction of the flexible conduit, the water droplets on the surface of the flexible conduit can be effectively blown off. Then the flexible conduit enters the cutting assembly 4. The power wheel 41 drives the flexible conduit to move forward, and the cutting blade 42 cuts it. The cut flexible conduit falls onto the conveyor belt 51. The compressed air assembly 53 supplies air to the conduit 52. The airflow blown out through the air hole 521 can quickly blow the flexible conduit to the collection platform 54 for collection.

The water-cooled box 1 includes an inlet chamber 11 and an outlet chamber 12. The outlet chamber 12 is located at both ends of the inlet chamber 11. The liquid level in the outlet chamber 12 is lower than that in the inlet chamber 11. The outlet chamber 12 is connected to the water tank 13 through an inlet pipe 15. The inlet chamber 11 is connected to the output end of the water pump 14 through an outlet pipe 16, ensuring the circulation of water in the water-cooled box 1, so that the flexible conduit is fully cooled, and improving the cooling efficiency and uniformity.

[0027] As a further preferred embodiment, the water blowing tray 21 is evenly distributed with eight rows of air channels 212, with four air channels in each row, to enhance the water blowing effect, ensure that water droplets on the surface of the soft tube are completely removed, provide a dry soft tube for subsequent cutting, and improve the cutting quality.

[0028] As a further preferred embodiment, an inclined conveying plate 55 is provided between the collection platform 54 and the conveyor belt 51, so that the soft tube can be smoothly transferred from the conveyor belt 51 to the collection platform 54, avoiding the soft tube from falling or stacking during the transfer process, and ensuring the orderly collection.

[0029] As a further preferred embodiment, a guide frame 3 is provided between the water blowing assembly 2 and the cutting assembly 4. Two sets of guide rollers 31 are symmetrically provided on the guide frame 3, which guide and limit the soft tube after water blowing, ensuring that the soft tube accurately enters the cutting assembly 4.
