[0002] In order to further enhance the rigidity and prevent bending during the use of medical composite tubes, a layer of stainless steel wire is woven on the outer surface. After weaving, the stainless steel wire layer is coated on the outer surface and cannot be used directly. On this basis, the surface of the composite tube needs to be pulled and reflowed. The purpose is to melt the outer tube material so that the stainless steel layer can be integrated into the outer tube due to the tension, and the surface is shaped and treated to meet the use requirements. The current process is to separate the weaving and reflowing. During this period, the woven steel wire needs to be fixed and drawn, and the composite tube needs to be protected during transportation to prevent damage to the braided wire. In addition, a separate device is required to perform hot reflow on the woven composite tube.

[0003] At present, the existing process requires separate equipment to complete weaving and reflow, which increases equipment, personnel costs and site occupancy. Utility Model Content

[0007] On the basis of the above technical solution, the medical tube braided reflux device of the utility model can also be improved as follows:

[0008] Wherein, the heating unit is arranged on the right side of the heating chamber, and the heating unit is connected to the heating chamber through a hot air inlet.

[0014] Compared with the prior art, the medical tube braiding and reflux integrated device provided by the utility model has the following beneficial effects: by setting a heating chamber, the composite tube is locally heated, the heating temperature can reach the melting point of the composite tube material, and at the same time, the stainless steel wire on the braiding machine head melts in the outer layer and merges with the outer layer of the composite tube; by setting a tractor, the composite tube is pulled through the shaping port by traction force, so that the excess plastic particles on the outer layer of the composite tube are scraped off, and the size of the composite tube is shaped to maintain the surface finish of the composite tube; the utility model

[0022] In order to make the purpose, technical solution and advantages of the implementation mode of the present invention clearer, the technical solution in the implementation mode of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the implementation mode of the present invention.

[0023] like Figure 1-3 As shown, it is a structural schematic diagram of a medical tube braiding reflux device provided by the utility model. In this device, there are a braiding head 1, a heating unit 2, a steel wire braiding position 3, a heating chamber 4, a shaping port 5, a cooling port 6, a tractor 7 and a composite tube 8; the composite tube 8 passes through the braiding head 1, the heating chamber 4, the cooling port 6 and the tractor 7 in sequence; the front end of the composite tube 8 is connected to the tractor 7, and the tractor 7 is used to pull the composite tube 8 forward; the braiding head 1 is used to braid stainless steel wire for the outer layer of the composite tube 8; the heating chamber 4 is used to melt the outer layer of the composite tube 8; the shaping port 5 is used to scrape off excess plastic particles on the outer layer of the composite tube 8 and shape the size of the composite tube 8; the cooling port 6 is used to cool the composite tube 8.

[0024] When in use, the whole device is powered by the tractor 7 for the overall forward displacement of the composite tube 8. The whole process is as follows: the heating unit 2 blows hot air into the heating chamber 4, and the hot air temperature can be adjusted according to different materials. When the hot air enters the heating chamber 4, the heat of the hot air is evenly covered on the surface of the composite tube 8 due to the guide groove inside the heating chamber 4. When the hot air is discharged from the outlet of the heating chamber, the outlet temperature is basically close to the internal temperature after the internal temperature accumulation, so that the surface plastic of the composite tube 8 is basically softened before entering the heating chamber;

[0025] When the braided composite tube 8 enters the heating chamber, the temperature is maintained and the plastic continues to soften. Due to the tension on the surface of the steel wire, the steel wire is completely embedded in the outer layer.

[0026] When the composite tube 8 passes through the end of the heating chamber, it passes through the shaping port 5, so that the surface size of the composite tube 8 is reshaped, and the plasticized outer layer of plastic is covered with the braided layer;

[0027] When the composite pipe 8 passes through the cooling port 6, the compressed air flows out of the cooling port to cool the composite pipe 8. At this time, after passing through the cooling port 6, the composite pipe 8 is cooled and shaped.

[0028] Among them, in the above technical solution, the heating unit 2 is arranged on the right side of the heating chamber 4, and the heating unit 2 and the heating chamber 4 are connected through the hot air inlet.

[0029] Furthermore, in the above technical solution, a vortex guide block is provided at the hot air inlet.

[0030] Furthermore, in the above technical solution, the shaping port 5 is arranged at the front end outlet of the heating chamber 4 , and a sizing sleeve is arranged on the inner wall of the shaping port 5 .

[0031] Furthermore, in the above technical solution, the wire braiding position 3 is located at the front end of the braiding machine head 1.

[0032] Furthermore, in the above technical solution, a heating cavity is provided inside the heating cavity 4 .

[0033] Furthermore, in the above technical solution, a guide groove is provided inside the heating chamber of the heating chamber 4 .

[0034] Specifically, the principle of the utility model is: the whole device is powered by the tractor 7 for the overall forward displacement of the composite tube 8. The whole working process is as follows: the heating unit 2 blows hot air into the heating chamber 4, and the hot air temperature can be adjusted according to different materials. When the hot air enters the heating chamber 4, due to the guide groove inside the heating chamber 4, the heat of the hot air is evenly covered on the surface of the composite tube 8. When the hot air is discharged from the outlet of the heating chamber, the outlet temperature is basically close to the internal temperature after the internal temperature accumulation, so that the surface plastic of the composite tube 8 is basically softened before entering the heating chamber;

[0035] When the braided composite tube 8 enters the heating chamber, the temperature is maintained and the plastic continues to soften. Due to the tension on the surface of the steel wire, the steel wire is completely embedded in the outer layer.

[0036] When the composite tube 8 passes through the end of the heating chamber, it passes through the shaping port 5, so that the surface size of the composite tube 8 is reshaped, and the plasticized outer layer of plastic is covered with the braided layer;

[0037] When the composite pipe 8 passes through the cooling port 6, the compressed air flows out of the cooling port to cool the composite pipe 8. At this time, after passing through the cooling port 6, the composite pipe 8 is cooled and shaped.
